[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Example 1
[0021] like Figure 1 , Figure 2As shown, the piston pin processing mechanism with adjustable chamfering angle in this example includes a base 1, a clamping mechanism 2, a shifting mechanism 9, a power mechanism 3, and a chamfering cutter 6. The clamping mechanism 2 is installed on the left top surface of the base 1, and the shifting mechanism 9 is installed on the right top surface of the base 1.
[0022] A power mechanism 3 is installed between the clamping mechanism 2 and the shifting mechanism 9. The shifting mechanism 9 is a telescopic cylinder type. The shifting mechanism 9 moves the power mechanism 3 toward the clamping mechanism 2 or away from the clamping mechanism. In this example, a T-shaped slide groove is formed on the top surface of the base 1, and the slide groove extends along the moving direction of the moving end of the shifting mechanism. A second slide is added, and the bottom of the second slide 8 is T-shaped to slide with the T-shaped slide groove. The power mechanism 3, such as a drive motor, is fixed on the second slide 8. The second slide 8 is connected to the moving end of the shifting mechanism 9.
[0023] In this example, a slide 7, a tool holder 4 and a connector 5 are added. The bottom of the slide 7 is also T-shaped and slides with the T-shaped slide groove. The slide 7 and the slide 2 8 slide back and forth on the same straight line. The slide 1 7 is between the clamping mechanism 2 and the slide 2 8. The tool holder 4 is installed on the top surface of the slide 7. If plugged in, a socket is formed on the top surface of the slide 1 7, and a column 41 is formed on the bottom surface of the tool holder 4. The column 41 is inserted into the socket to place the tool holder 4 on the top surface of the slide 1 7.
[0024] The chamfering knife 6 is rotatably connected to the knife seat 4. For example, the chamfering knife is rotatably connected to the knife seat through a bearing, etc., and the front and rear ends of the chamfering knife 6 extend from the front and rear ends of the knife seat 4. The plug-in component 5 is fixed at the output end of the power mechanism 3. For example, the plug-in component is cylindrical, which is sleeved at the output end of the power mechanism and fastened by screws, etc.
[0025] The tail end of the chamfering knife 6 is plugged into and matched with the connector 5 along the axial direction and the two are constrained circumferentially. Specifically, the tail end of the chamfering knife 6 is rectangular, and the corresponding connector barrel cavity is also rectangular. The tail end of the chamfering knife 6 is inserted in the barrel cavity of the connector 5, and the two can slide along the axial direction, but the two rotate synchronously in the circumferential direction to form a constraint.
[0026] In this example, an elastic member 10 is added between the slide 1 7 and the base 1, and the elastic member 10 is used to push the slide 1 7 toward the power mechanism 3. For example, the clamping mechanism 2 includes a bracket 21, a clamp block 1 23, a clamp block 24, a support seat 25, and a telescopic mechanism 22. The support seat 25 and the bracket 21 are fixed on the base 1, and the clamp block 24 is fixed on the top surface of the support seat 25. The telescopic mechanism 22 is installed at the horizontal end of the bracket 21 above the clamp block 24, such as a telescopic cylinder type. The clamp block 1 23 is fixed at the moving end of the telescopic mechanism 22, and the clamp block 1 23 is reciprocated by the telescopic mechanism 22 toward the clamp block 24, so that the clamp block 1 and the clamp block 2 cooperate to clamp the piston pin, etc.
[0027] In this example, the elastic member is a spring, and the elastic member 10 is located between the slide 1 7 and the support seat 25. Under the action of the elastic member, the slide 1 is pushed toward the slide 2 to keep the tail end of the chamfering knife and the connector in an inserted state.
[0028] Driven by the power mechanism, the chamfering knife rotates, and the shift mechanism drives the chamfering knife to move to the clamping mechanism for chamfering operation. When the chamfering knife needs to be replaced, the slide seat 1 is moved forward to disengage the chamfering knife from the connector, and the knife holder is disengaged from the slide seat 1. Then, the knife holder equipped with another type of chamfering knife is inserted on the slide seat 1.

All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
