Description

Impact device and its linkage assembly for impact

The present invention relates to an impact device for generating impact force, in particular to an impact linkage component of the impact device.

At present, the use of impact-actuated devices is widely used, such as power generation, spray guns, spray heads, object conveying, toy guns, and others. When a general device generates an impact force, it needs to use a complicated mechanism to release the accumulated energy to generate the impact force and return to its original state for the next operation.

However, in the conventional device, in the process of repeatedly generating the impact force, the interval time between each impact force is too long, so a manual operation method is generally adopted to shorten the interval time between each impact force, which is not conducive to the automatic operation process.

Furthermore, although the conventional device adopts an automatic design, it needs to configure a plurality of actuators to achieve the functions of accumulating and releasing energy respectively, which makes the overall configuration complicated and increases the complexity of the actuator control.

Therefore, how to overcome the above-mentioned various problems of the conventional technology has become an urgent problem to be solved at present.

In view of the above-mentioned deficiencies in the prior art, the present invention provides a linkage assembly for impact, which includes: a base; a first acting member pivotally connected to the base; and a second acting member pivotally connected to the first acting member ; And the clutch member is arranged on the base in a displaceable manner.

In the aforementioned impact linkage assembly, the first acting member is a rocker structure.

In the aforementioned impact linkage assembly, the first acting member is pivotally connected to the base through a first shaft member. For example, the first shaft member is sleeved with a first elastic element fixed to the first action member.

In the aforementioned impact linkage assembly, the second acting member is a rocker structure.

In the aforementioned impact linkage assembly, the second acting member is pivotally connected to the first acting member through a second shaft member. For example, the second shaft member is sleeved with a second elastic element fixed to the second acting member.

In the aforementioned impact linkage assembly, the base is provided with a groove, so that the clutch member is slidably connected to the groove. For example, the clutch element is connected to the base through a telescopic element.

The present invention also provides an impact device, which includes: the aforementioned impact linkage assembly; and an actuator, which is fastened to the base.

In the aforesaid impact device, an impact component arranged corresponding to the second acting member is further included. For example, the impact component includes a fixed seat, a power member disposed on the fixed seat, and a target member disposed on the power member, so that the target member abuts against the second acting member. The power element is a spring and/or the target element is a cylinder. In addition, the actuator drives the base to displace, and displaces the second action piece together, so that the impact component generates power.

In the aforementioned impact device, a stopper disposed corresponding to the base is further included to drive the base to displace by the actuator, and the stopper blocks the clutch element.

As can be seen from the above, the impact device and its impact linkage assembly of the present invention mainly rely on the design of the double pivot structure of the first acting member and the second acting member, so that the second acting member can actuate the impact member. The target piece produces impact action, and the second action piece can bypass the target piece and return to its original state, so the impact linkage component of the impact device of the present invention can not only release the target piece to generate impact action, but also return to its original state.

Furthermore, the impact device and its impact linkage assembly of the present invention can simplify the overall configuration and reduce the complexity of actuator control by means of mechanism design.
