According to this embodiment, the moving plate 212 is made linearly movable in the vertical direction by the driving of the driving device 213. At the same time, the clamp 30 can clamp the piston pin during drilling operation. Compared with the traditional mode, the utility model adds more processing stations by arranging a plurality of drilling tool assemblies 20 and a plurality of clamps 30 on the base 10, thereby reducing the occupied space. The utility model can not only adjust the distance between the drilling tool assembly 20 and the clamp 30, but also drive the drilling tool assembly 20 to perform drilling operation by matching the connecting part 2122, the executing part 2123 and the driving component 2131.

It is understood that the connection portion 2122 may be a connection seat or a nut seat, etc. The rotary drive mechanism 21312 is a motor; for example, a gear motor, a servo motor, a stepper motor, or the like. The drive assembly 2131 may also be a linear drive mechanism; the linear driving mechanism can be a linear motor, a hydraulic cylinder or an air cylinder, etc. When the driving assembly 2131 is a linear driving mechanism, the connection 2122 is a connection base; the nut seat is adapted to the first screw 21311. The actuator 2123 may be a guide holder, a rail, a slide rail, or the like. The guide 2132 may be a guide bar, a slide or a slideway, etc. The guide portions 2132 and the members of the execution portion 2123 are sequentially in one-to-one correspondence. For example, when the guide 2132 is a guide bar, the actuator 2123 is a guide holder.

According to this embodiment, the rotation driving mechanism 21312 drives the first screw 21311 to rotate, and the cooperation of the execution portion 2123 and the guide portion 2132 can prevent the moving plate 212 from rotating along with the first screw 21311, so as to realize lifting of the moving plate 212.

Referring to fig. 1 and 4, in some embodiments, the drilling assembly 20 includes a damping member 230 removably coupled to the exterior of the drilling member 220, the damping member 230 including a mounting plate 231, an end plate 232 proximate a bit portion of the drilling member 220, at least two legs 233 positioned between the mounting plate 231 and the end plate 232 and spaced apart circumferentially, and a resilient member 234 positioned between each leg 233 and the end plate 232. Alternatively, the elastic member 234 may be a spring or elastic rubber, or the like. Preferably, the elastic member 234 is a spring.

According to this embodiment, the engagement of the end plate 232 and the resilient member 234 during the drilling operation of the drilling assembly 20 causes the resilient member 234 to deform and cushion. And thus, errors or damage to the work piece caused by the drill assembly 20 may be avoided.

Referring to fig. 1 and 5-6, in some embodiments, the clamp 30 includes at least two support plates 31 disposed opposite each other, a plurality of support seats 32 disposed between the at least two support plates 31 and circumferentially spaced apart, and a clamping assembly 33 disposed between each adjacent two of the support seats 32, the support plates 31 adjacent to the drill member 220 having axially extending receiving holes 311.

According to this embodiment, by so doing, it is possible to facilitate the operation of the second screw 333 by the worker, thereby improving the processing efficiency.

Specifically, the working principle of the multi-station piston pin machining device is as follows: the workpiece is placed in the accommodating hole 311, and the second screw 333 is rotated by the handle 334 to cause the clamp block 332 to clamp the workpiece around the base 331 with a rotational movement facing the accommodating hole 311. The rotation driving mechanism 21312 drives the first screw 21311 to rotate, and the cooperation of the executing portion 2123 and the guiding portion 2132 can prevent the moving plate 212 from rotating along with the first screw 21311, so that the drilling assembly 20 continuously moves linearly towards the workpiece, and thus the drilling assembly 20 can perform drilling operation on the workpiece.

It should be noted that, the model specifications of the rotary driving mechanism 21312 and the linear driving mechanism need to be determined according to the actual specifications of the device, and the specific model selection calculation method adopts the prior art in the field, so detailed description thereof is omitted.

The power supply of the rotary drive mechanism 21312 and the linear drive mechanism and the principles thereof will be apparent to those skilled in the art and will not be described in detail herein.

The foregoing is only illustrative of the present utility model and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present utility model.
