[0031] like Figure 1-Figure 3 As shown, a robot arm clamp for camshaft processing of the utility model includes a first clamping mechanism 1, a second clamping mechanism 2 and an adjustment component arranged at the end of the robot arm, the first clamping mechanism 1 includes a first plate body 11 and a first clamping component 12, the second clamping mechanism 2 includes a second plate body 21 and a second clamping component 22, the first clamping component 12 and the second clamping component 22 are both used to clamp the camshaft 4, and there is an angle between the first clamping component 12 and the second clamping component 22. When the robot arm is working, the unprocessed camshaft 4 can be clamped by the first clamping mechanism 1 in advance. After the unprocessed camshaft 4 is transferred to the gear hobbing machine, the processed camshaft 4 on the gear hobbing machine is clamped by the second clamping mechanism 2. The robot arm controls the first clamping mechanism 1 to rotate, and the rotation angle is the angle between the first clamping component 12 and the second clamping component 22, driving the second clamping mechanism 2 to rotate, so that the camshaft 4 clamped by the second clamping mechanism 2 rotates away from the gear hobbing machine, and the camshaft 4 clamped by the first clamping mechanism 1 rotates toward the gear hobbing machine, and the unprocessed camshaft 4 clamped by the first clamping mechanism 1 is placed on the gear hobbing machine, and the robot arm then drives the first clamping mechanism 1 and the second clamping mechanism 2 to leave the gear hobbing machine. The posture adjustment of the robot arm is effectively reduced, and the feeding efficiency is increased.

[0032] In this embodiment, the adjustment component is arranged on the first plate body 11, and the adjustment component is used to adjust the angle between the first clamping component 12 and the second clamping component 22. Specifically, the adjustment component includes a first driving member 3, and a mounting groove 111 is provided on the first plate body 11, and the first driving member 3 is fixedly installed in the mounting groove 111. In other embodiments, it is also not necessary to provide the mounting groove 111 on the first plate body 11, and the first driving member 3 is directly fixedly installed on the first plate body 11, and then a corresponding receiving groove is provided on the second plate body 21. The first driving member 3 is a servo motor, and the first driving member 3 is provided with a driving shaft 31, and a driving groove 211 is provided on the second plate body 21, and the driving shaft 31 is inserted in the driving groove 211. When the first driving member 3 is working, the second plate body 21 is driven to rotate by the driving shaft 31, thereby driving the second clamping component 22 on the second plate body 21 to rotate, and changing the angle between the first clamping component 12 and the second clamping component 22 to adapt to different models of camshafts 4. It should be noted that a limit block 32 is disposed at the end of the driving shaft 31 to prevent the second plate 21 from falling off the driving shaft 31 .

[0033] In this embodiment, two groups of first clamping components 12 are provided, and the two groups of first clamping components 12 are respectively provided at both ends of the first plate body 11; two groups of second clamping components 22 are provided, and the two groups of second clamping components 22 are respectively provided at both ends of the second plate body 21. When the robotic arm is working, the corresponding clamping component can be selected for clamping according to actual conditions, thereby further reducing the posture adjustment of the robotic arm.

[0034] In this embodiment, a rotating connection column 112 is provided on the first plate body 11, and the rotating connection column 112 is used for transmission connection with the mechanical arm. The axial distance between the first clamping component 12 and the rotating connection column 112 is equal to the axial distance between the second clamping component 22 and the rotating connection column 112, and the axis of the driving shaft 31 is colinear with the axis of the rotating connection column 112. When the mechanical arm controls the first rotating mechanism to rotate, it can ensure that the second clamping component 22 rotates to overlap with the original position of the first clamping component 12, so as to quickly pick up and put down materials.

[0035] In this embodiment, the first clamping assembly 12 has the same structure as the second clamping assembly 22. The first clamping assembly 12 includes a mounting block 51, a first clamping block 52, a second clamping block 53 and a second driving member 54, and the second driving member 54 is a micro motor. The mounting block 51 is fixedly connected to the first plate 11, and a slide groove 511 is provided on the mounting block 51.

The second driving member 54 is fixedly installed on the mounting block 51, and the second driving member 54 is transmission-connected with the double-headed screw 512. When the micro motor works, it drives the double-headed screw 512 to rotate, so that the first clamping block 52 and the second clamping block 53 can clamp and take materials or loosen and release materials. In some other embodiments, the second driving member 54 and the double-headed screw 512 can also be replaced by a telescopic cylinder to push the first clamping block 52 and the second clamping block 53 to move.

[0036] The method of using the utility model is as follows:

[0037] First, the robot arm works to control the corresponding micro motor of the first clamping assembly 12 to work, so that the first clamping block 52 and the second clamping block 53 of the first clamping assembly 12 clamp the unprocessed camshaft 4 on the material rack and transfer the unprocessed camshaft 4 to the gear hobbing machine. At the same time, the second clamping assembly 22 moves to the processed camshaft 4.

[0038] Then, the robot arm controls the corresponding micro motor of the second clamping assembly 22 to work, so that the first clamping block 52 and the second clamping block 53 of the second clamping assembly 22 clamp the processed camshaft 4 on the gear hobbing machine;

[0039] Finally, the robotic arm controls the rotating connecting column 112 to rotate, driving the first clamping component 12 to rotate, thereby driving the second clamping component 22 to rotate, so that the camshaft 4 clamped by the second clamping component 22 rotates away from the gear hobbing machine, and at the same time, the camshaft 4 clamped by the first clamping component 12 rotates toward the gear hobbing machine, and the unprocessed camshaft 4 clamped by the first clamping component 12 is placed on the gear hobbing machine, and the robotic arm then drives the first clamping component 12 and the second clamping component 22 to leave the gear hobbing machine.
