[0002] The industrial robot fixture module is a key configurable component of the automation system. The industrial robot fixture module is an actuator with a gripper. Its main application is to pick up, transfer and place objects. The industrial robot fixture can be standardized or custom-designed to adapt to the physical specifications of the workpiece that the robotic equipment must grasp. The industrial robot fixture has features such as adjustable force and stroke characteristics, enabling the robotic equipment to perform tasks with human-like precision and dexterity.

[0003] In the existing technology, industrial robot clamps are usually driven by cylinders, which drive the clamps to rotate so that the ends of the clamps turn from the outside to the inside, and the clamps are used to fix the items to be clamped. However, in actual use, when the industrial robot clamps need to be used to clamp different items, it is usually necessary to disassemble the clamps and replace them with different clamps to clamp the new items. However, the process of disassembling and assembling the clamps is relatively cumbersome and usually takes a lot of time, affecting production efficiency. Therefore, it is necessary to improve an industrial robot clamp to solve the above problems. Utility Model Content

[0028] Furthermore, the outward expansion component 21 includes a motor 211, which is fixedly mounted on the left side of the fixed plate 1. A bidirectional threaded rod 212 is fixedly mounted on the right side of the transmission shaft of the motor 211.

A limiting rod frame 214 is mounted on the internal sliding of the moving block 213 to facilitate adjustment of the spacing between the fixed clamps 223 on both sides through the outward expansion component 21.

[0029] Furthermore, two limiting rod frames 214 are provided, and the inner sides of the two limiting rod frames 214 are fixedly mounted to the outer side of the fixing plate 1 , thereby improving stability.

[0030] Furthermore, the clamping assembly 22 includes a limiting connecting plate 221, which is fixedly installed on the bottom of the moving block 213.

[0032] Embodiment 2:

[0033] See also Figure 5 , and combined with Example 1, it is further obtained that the quick-install claw mechanism 3 includes a fixed positioning slot block 31, the fixed positioning slot block 31 is fixedly installed on the front and back of the rotating shaft 222, a cross plug block 32 is slidably installed inside the fixed positioning slot block 31, a mounting shaft 33 is fixedly installed on the outside of the cross plug block 32, an external positioning slot block 34 is fixedly installed on the outside of the mounting shaft 33, an external clamping claw 35 is fixedly installed on the outside of the mounting shaft 33, a bolt 36 is provided inside the fixed positioning slot block 31, and a nut 37 is threadedly installed on the outside of the bolt 36, which facilitates the installation of the external clamping claw 35 through the quick-install claw mechanism 3.
