[0021] Figure 6 This is a schematic diagram of the connection between the present invention and a robot. Detailed Implementation

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] See Figure 1This utility model is a robot integrated gripper for picking up intermediate shafts, including a fixed fork gripper, a finished workpiece gripper, a shaft tube gripper, a gripper base, and a pneumatic module. Three pneumatic modules 2 are installed on the bottom connecting plate of the gripper base 1. The fixed fork gripper 5, the finished workpiece gripper 6, and the shaft tube gripper 7 are respectively installed on the bottom of the corresponding pneumatic module 2.

[0024] See Figure 6 The upper end of the gripper base 1 is connected to the end of the robot 9. The robot 9 is mounted on the base 10 and the pneumatic module 2 is opened and closed by the PLC, thereby realizing the opening and closing of different grippers of the integrated gripper 11.

[0025] Two pneumatic modules 2 are arranged along the length of the connecting plate of the claw base 1, and one pneumatic module 2 is arranged along the width of the connecting plate of the claw base 1 to save space.

[0026] The pneumatic module 2 includes a connector 21 and a pneumatic clamp 22. The connector 21 is installed on the bottom connecting plate of the claw base 1, and the pneumatic clamp 22 is installed on the bottom of the connector 21.

[0027] See Figure 2 , Figure 3 The fixed fork gripper 5 includes a guide rod 51, a spring 52, a floating guide plate 53, a center positioning block 54, and clamping plates 55. The guide rod 51 is fixed to the bottom of the pneumatic module 2, and the lower end of the guide rod 51 passes through the center positioning block 54. The spring 52 is sleeved on the outside of the guide rod 51, and the two ends of the spring 52 abut against the boss of the guide rod 51 and the top surface of the center positioning block 54, respectively. The middle part of the floating guide plate 53 is sleeved on the outside of the guide rod 51 and is located above the center positioning block 54. The two ends of the floating guide plate 53 pass through the through holes on the surface of the clamping plates 55. The upper ends of the two clamping plates 55 are connected to the movable end of the pneumatic module 2, and the lower parts of the two clamping plates 55 are located on both sides of the center positioning block 54.

[0028] Limiting blocks are provided at the lower end of the guide rod 51 and at both ends of the floating guide plate 53 to prevent the center positioning block 54 from falling off the lower end of the guide rod 51 and the two ends of the floating guide plate 53 from coming out of the clamping piece 55.

[0029] When the fixed fork gripper 5 grasps the fixed fork 8, the two gripping plates 55 are in the open state under the action of the pneumatic gripper 22. The robot 9 drives the gripper to move downward, and the center positioning block 54 pushes into the spline of the fixed fork 8. The center positioning block 54 moves upward along the guide rod 51, the spring 52 is compressed, and the floating guide plate 53 moves upward, so that the fixed fork 8 enters the clamping area between the two gripping plates 55. The pneumatic gripper 22 drives the two gripping plates 55 to clamp the fixed fork 8.

[0030] When the fixed fork 8 is placed, after the robot 9 moves the gripper to the designated position, the pneumatic clamp 22 drives the two clamping plates 55 to open. The elastic force of the spring 52 provides axial thrust to the fixed fork 8. Combined with the weight of the fixed fork 8, the fixed fork 8 is released, so that the fixed fork 8 can be accurately placed with the positioning fixture.

[0031] The cooperation between the center positioning block 54 and the floating guide plate 53 enables floating centering, which can play a vertical centering role for fixed forks of different sizes and specifications.

[0032] See Figure 4 The finished workpiece gripper 6 includes a connecting positioning block 61, a finished workpiece gripper body 62, an ear hole positioning block 63, an anti-rotation block 64, and a bracket 65. The upper end of the bracket 65 is fixed to the bottom rear side of the pneumatic module 2, and the anti-rotation block 64 is installed on the lower front side of the bracket 65. The upper ends of the two finished workpiece gripper bodies 62 are connected to the movable end of the pneumatic module 2 by the connecting positioning block 61. The lower inner side of the two finished workpiece gripper bodies 62 is respectively equipped with an ear hole positioning block 63, and the anti-rotation block 64 is located between the two ear hole positioning blocks 63.

[0033] See Figure 2 When the finished workpiece gripper 6 grasps the finished workpiece 3, the finished workpiece gripper body 62 is in the open state under the action of the pneumatic clamp 22. When the robot 9 moves to the gripping position, the pneumatic clamp 22 drives the finished workpiece gripper body 62 to close, the ear hole positioning block 63 is inserted into the fixed fork ear hole of the finished workpiece 3, and the finished workpiece gripper body 62 clamps and fixes it.

[0034] When the finished workpiece 3 is placed in the finished workpiece gripper 6, the pneumatic clamp 22 drives the finished workpiece gripper body 62 to open, and the finished workpiece 3 falls into the placement area under its own gravity.

[0035] The ear hole positioning block 63 has the function of detecting the deformation of the ear hole during pressing of the finished workpiece 3. If the ear hole structure is abnormal, the ear hole positioning block 63 cannot be inserted. The anti-rotation stop block 64 can prevent the finished workpiece 3 from rotating and tipping due to its own weight, thus avoiding the problem of the finished workpiece colliding with the machine.

[0036] See Figure 5 The shaft tube gripper 7 includes a connecting positioning block 2 71 and a shaft tube gripper body 72. The upper ends of the two shaft tube gripper bodies 72 are connected to the movable end of the pneumatic module 2 by the connecting positioning block 2 71. The lower inner side of the two shaft tube gripper bodies 72 is V-shaped.

[0037] See Figure 2When the shaft and tube gripper 7 grasps the shaft or tube part 4, the gripper body 72 is in the open state under the action of the pneumatic gripper 22. When the robot 9 moves to the grasping position, the pneumatic gripper 22 drives the gripper body 72 to close, and the gripper body 72 clamps the shaft or tube part 4.

[0038] When placing shaft or tube parts 4, the pneumatic clamp 22 drives the shaft or tube clamp body 72 to open, and the shaft or tube parts 4 fall into the placement area under their own gravity.

[0039] The V-shaped shaft and tube gripper body 72 can adaptively grip shaft or tube parts 4 of different sizes without requiring the shaft or tube part 4 to be changed due to different sizes.

[0040] This invention integrates a fixed fork gripper, a shaft tube gripper, and a finished workpiece gripper onto a single gripper base, enabling the gripping and placement of multiple parts of different specifications. This replaces manual loading and unloading, improves the assembly efficiency of the intermediate shaft, and reduces costs.
