Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1 to Figure 3, the device of the pump cover for dismantling automobile electric fuel pump of the present invention, comprise matrix 4, matrix 4 is provided with driving gear 1, circumference along driving gear 1 is evenly equipped with at least 2 driven gears 2 engaged with driving gear be arranged on matrix, each driven gear 2 is all connected with grabs bar 3, described bar 3 of grabbing comprises the connecting portion 5 be connected with corresponding driven gear 2 and the pump cover grasping part 6 be connected with connecting portion 5 be positioned at outside matrix, described driving gear 1 drives each pump cover grasping part 6 to be synchronized with the movement by each driven gear to make each pump cover grasping part 6 remain identical apart from the distance of the axial line of driving gear.When arranging, the type of each driven gear selected is all identical with size, and each pump cover grasping part is uniform along the circumference of driving gear.During use, by rotating driving gear 1, each driven gear 2 synchronous axial system can be driven simultaneously, and then each pump cover grasping part 6 can be driven to be synchronized with the movement, pump cover grasping part 6 can gradually near driving gear under the drive of driven gear 2, also can gradually away from driving gear, namely pump cover grasping part 6 can become large gradually apart from the distance of the axial line of driving gear, also can diminish gradually.Further, adopt said apparatus, each pump cover grasping part 6 moves to any position all can ensure that each pump cover grasping part 6 is positioned at one circumferentially.Pump cover grasping part 6 can be determined according to the size of the pump cover of automobile electric fuel pump apart from the distance of the axial line of driving gear.The extracting tool that one is applicable to the above-mentioned pump cover of dismounting can be formed after pump cover grasping part 6 is apart from the distance adjustment of the axial line of driving gear.When above-mentioned matrix 4 is arranged, be preferably arranged to circle.Be convenient to like this observe the distance of each pump cover grasping part 6 apart from driving gear.Thus be convenient to the size confirming the final extracting tool formed.
The present invention in use, can first according to the size adjusting of pump cover, each grabs the position of bar 3, make the size of device of the present invention and pump cover adaptive.Then syndeton corresponding with on pump cover for the pump cover grasping part 6 of grabbing bar 3 is connected, the embodiment of above-mentioned pump cover grasping part 6 has multiple, and such as, shown in Fig. 4, pump cover grasping part 6 comprises a draw-in groove, pump cover is provided with corresponding floor 8, by draw-in groove and floor 8 clamping.Then by rotating driving gear 1, driven gear 2 can be driven to rotate, and driven gear 2 can drive corresponding pump cover grasping part 6 to be unscrewed by pump cover, and then pump cover can be dismantled.
Although can directly drive driving gear 1 to rotate by the gear teeth stirring driving gear 1, adjustment driving gear 1 be convenient not like this.For the ease of adjustment driving gear 1, be namely convenient to adjust the pump cover extracting tool that device of the present invention makes it to be formed required size, described driving gear 1 is connected with drive unit.This drive unit can be a handle be connected with the driving shaft of driving gear, by turning handle, driving gear 1 can be driven to rotate.This drive unit also can be a device with motor.Driven the rotating shaft of driving gear 1 by motor, and then drive driving gear 1 to rotate.Like this can be more laborsaving, and it is faster to regulate the speed.
On the basis of the above, in order to increase the scope of application of device of the present invention further, also in order to finely tune apart from the distance of the axial line of driving gear each pump cover grasping part 6, described connecting portion comprises along adjustment section 7 telescopic with the axial line vertical direction of driving gear.Above-mentioned adjustment section 7 can be one section of telescopic sleeve, by arranging locking mechanism to limit the distance of stretch out and draw back of sleeve on sleeve.Above-mentioned adjustment section 7 also can be the mechanisms such as the expansion link of air cylinder driven.Due to reasons such as the wear errors that produces after alignment error or Long-Time Service, may cause certain pump cover grasping part 6 can not synchronous adjustment apart from the distance of the axial line of driving gear apart from the distance of the axial line of driving gear and other pump cover grasping part 6, at this moment by above-mentioned adjustment section 7, this pump cover grasping part 6 is finely tuned apart from the distance of the axial line of driving gear, thus the accuracy that device of the present invention uses and reliability can be guaranteed.On the basis of the above, as shown in Figure 3, described connecting portion also comprise be connected with pump cover grasping part 6 along the supporting section 9 arranged with the axis parallel direction of driving gear 1, one end and the supporting section 9 of described adjustment section 7 are rotatably assorted.Be convenient to the adjustment of floor angle on the draw-in groove of pump cover grasping part 6 and pump cover like this.Similar, in order to further facilitate adjustment, described connecting portion also can comprise along vertical adjustment section telescopic with the axis parallel direction of driving gear.
The number of above-mentioned driven gear can be 2,3,4 etc.Found through experiments, when the number of described driven gear 2 is 3, dependability is higher, and whole apparatus structure is simple, is convenient to dismounting and maintenance.
