As shown in fig. 1, the mounting apparatus 10 of the present utility model includes a pin mounting device 100 and a clamp. The pin mounting device 100 has a first mounting member 110 and a second mounting member 120, and the clamp may be, for example, a flat nose pliers (also referred to as a vice) or other clamping device, the clamp has a first jaw and a second jaw, the pin mounting device 100 is disposed between the first jaw and the second jaw, and the first mounting member 110 and the second mounting member 120 are respectively pushed by the first jaw and the second jaw to close to each other, so as to mount the pin 20 on the workpiece 30.
As shown in fig. 1, the installation apparatus 10 of the present utility model is illustratively described with respect to the installation of a double-ended stepped pin, and should not be construed as limiting the installation apparatus 10 of the present utility model.
As shown in fig. 1, a positioning portion 31 is provided on the outer peripheral surface of the workpiece 30, the positioning portion 31 is convex, a pin hole 32 is provided on the positioning portion 31 in the axial direction of the workpiece 30, and the pin 20 is interference fit with the pin hole 32.
As shown in fig. 1, the pin mounting device 100 of the present utility model includes a first mounting member 110 and a second mounting member 120, the first mounting member 110 having a first contact surface 111 and a second contact surface 112, and the second mounting member 120 having a third contact surface 121 and a fourth contact surface 122. Wherein, the first mounting piece 110 is located at one side of the positioning portion 31 along the axial direction of the workpiece 30, and the second mounting piece 120 is located at the other side of the positioning portion 31 along the axial direction of the workpiece 30. The first contact surface 111 abuts against the positioning portion 31 of the workpiece 30, the third contact surface 121 abuts against one end of the pin 20, the first and second binding clip approaches, and when the other end of the pin 20 is pushed into the pin hole 32 of the workpiece 30 to a predetermined position, the second contact surface 112 abuts against the fourth contact surface 122. Thus, when the pin 20 is mounted using the first mounting piece 110 and the second mounting piece 120, the third contact surface 121 is brought into contact with one end of the pin 20, and the other end of the pin 20 is pushed into the pin hole 32. The first contact surface 111 is brought into contact with the workpiece 30, so that the second mount 120 can be positioned by the first mount 110, and when the second contact surface 112 is brought into contact with the fourth contact surface 122, it is indicated that the other end of the pin 20 has entered the predetermined position in the pin hole 32. Therefore, the mounting position of the pin 20 can be positioned, the mounting precision of the pin 20 is improved, and the problems that the mounting depth is insufficient, the assembly precision is affected or the head of the pin 20 is extruded and deformed due to excessive mounting are avoided when the pin 20 is mounted.
As shown in fig. 1, 2 and 3, the first mounting member 110 and the second mounting member 120 are respectively provided with a guide rod 123 and a guide hole 113, the guide rod 123 and the guide hole 113 extend along a direction L in which the pin 20 enters the pin hole 32, and the guide rod 123 is inserted into the guide hole 113 to slidably connect the first mounting member 110 and the second mounting member 120. Thus, the moving direction between the first and second mounting members 110 and 120 can be guided by the engagement between the guide rod 123 and the guide hole 113, so that the first and second mounting members 110 and 120 can be moved in the direction in which the pin 20 enters the pin hole 32, and thus the direction of the force applied to the pin 20 by the second mounting member 120 can be maintained when the pin 20 is mounted using the first and second mounting members 110 and 120, preventing the pin 20 from being biased or inclined during the mounting process.
As shown in fig. 1 to 3, the guide rod 123 and the guide hole 113 are disposed on the second contact surface 112 and the third contact surface 121, respectively. Thus, the first mount 110 and the second mount 120 can be guided at the position where the first mount 110 and the second mount 120 abut. This allows the second contact surface 112 and the fourth contact surface 122 to be positioned, thereby improving the positioning accuracy of the first mount 110 and the second mount 120, and further improving the mounting accuracy of the pin 20.
As shown in fig. 1 to 3, the first contact surface 111, the second contact surface 112, the third contact surface 121, and the fourth contact surface 122 are perpendicular to the guide bar 123. By this, the first contact surface 111, the second contact surface 112, the third contact surface 121, and the fourth contact surface 122 are perpendicular to the guide rod 123, so that the urging force between the first contact surface 111 and the workpiece 30 can be perpendicular to the first contact surface 111, and the stability of the first attachment 110 can be improved.

The moving direction of the first mounting member 110 and the second mounting member 120 may be perpendicular to the second contact surface 112 and the fourth contact surface 122, so as to avoid sliding after the second contact surface 112 abuts against the fourth contact surface 122.
As shown in fig. 1, after the guide rod 123 is inserted into the guide hole 113, the second contact surface 112 is closer to the fourth contact surface 122 than the first contact surface 111. Thus, the first contact surface 111 and the second contact surface 112 can be formed in a stepped shape, and after the first contact surface 111 abuts against the workpiece 30, the portion between the second contact surface 112 and the first contact surface 111 abuts against the workpiece 30, thereby improving the stability of the first mount 110.
As shown in fig. 3, the third contact surface 121 is provided with an auxiliary hole 124, and the auxiliary hole 124 extends in a direction L in which the pin 20 enters the pin hole 32. Thus, when the third contact surface 121 abuts against one end of the pin 20, the pin 20 can be inserted into the auxiliary hole 124, and the auxiliary hole 124 limits the pin 20, so as to avoid the pin 20 from being deviated or inclined during the installation process.
As shown in fig. 3, the auxiliary hole 124 is shaped to fit the pin 20. Thus, by adapting the auxiliary hole 124 to the pin 20, stability of the pin 20 can be improved after the pin 20 enters the auxiliary hole 124, and rattling of the pin 20 when entering the pin hole 32 can be avoided, so that the pin 20 can be prevented from being deviated or inclined during installation.
As shown in fig. 1 and 2, the first contact surface 111 is provided with a receiving hole 114, and after the first contact surface 111 abuts against the workpiece 30, the receiving hole 114 communicates with the pin hole 32. By communicating the accommodation hole 114 in the first contact surface 111 with the pin hole 32, it is possible to provide an accommodation space for the pin 20 when the other end of the pin 20 is exposed through the pin hole 32, thereby avoiding the failure of the pin 20 to be attached to the correct position.
When the pin 20 is mounted by using the mounting apparatus 10 of the present utility model, the workpiece 30 is first fixed so that the axial direction of the pin hole 32 is the same as the moving direction of the first and second bits. The guide rod 123 is inserted into the guide hole 113 to slidably couple the first mount 110 with the second mount 120. One end of the pin 20 is inserted into the auxiliary hole 124, and the other end of the pin 20 is aligned with the pin hole 32, so that the first mounting member 110 and the second mounting member 120 are respectively located at two sides of the positioning portion 31, that is, corresponding positions at two ends of the pin hole 32. The first contact surface 111 is abutted against the positioning portion 31, the first clamp head is abutted against the first mounting member 110 on the side opposite to the first contact surface 111, the second clamp head is abutted against the second mounting member 120 on the side opposite to the third contact surface 121, the second mounting member 120 is pushed to move along the guide rod 123 toward the first mounting member 110 by the first clamp head and the second clamp head, and the other end of the pushing pin 20 is inserted into the pin hole 32 and is in interference fit with the pin hole 32.
