Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a mechanical claw for automation equipment. Background Art

[0002] A robotic gripper generally refers to a mechanical device used to grasp, clamp or manipulate objects. It is commonly found in industrial production lines, robots and automated equipment. They are usually made of various materials, such as metal, plastic or composite materials, and have different shapes and functions to adapt to various application scenarios. Robotic grippers can be integrated into automated systems to perform various tasks, such as assembly, packaging, and handling. By combining sensors, control systems and programmed instructions, robotic grippers can achieve precise movements and operations, thereby improving production efficiency, reducing costs, and reducing human intervention. In automated equipment, robotic grippers are often used to achieve unmanned or semi-automated production processes, making the production process more efficient, reliable and flexible.

[0003] At present, an existing device (such as patent number: CN214352514U) discloses a mechanical claw for mechanical automation equipment. The device can facilitate the staff to fix the mechanical claw on the relevant equipment by elastically supporting the positioning bracket through the reset spring, and then when the staff turns the knob to drive the fastening screw to abut and position the positioning bracket again, it can facilitate the staff to firmly fix the mechanical claw on the relevant equipment. In addition, during the use of the mechanical claw, the matching combination of the elastic clamping handle and the positioning clamping claw can facilitate the staff to regularly replace the clamping claw of the mechanical claw, thereby avoiding the wear of the mechanical claw during long-term use, resulting in low clamping and positioning ability.

[0004] However, during the implementation of the above technical solution, it was found that at least the following technical problems exist: when the mechanical claw is in use, the clamping position of the mechanical claw cannot be further extended. When the size of the clamped workpiece changes, the mechanical claw of the device can only be replaced. Therefore, the user needs to prepare a variety of mechanical claws of different specifications, and the applicability needs to be improved. Utility Model Content

[0025] The embodiment of the present application effectively solves the technical problem of insufficient applicability of existing devices by providing a mechanical claw for automation equipment. By inserting the end of a straight-ended gear into a straight-ended groove and rotating it, the rotating shaft as a whole drives the active bevel gear to rotate in the expansion groove and the slide groove respectively. At this time, the active bevel gear will mesh with the driven bevel gear, so that the driven bevel gear drives the lead screw to rotate and transmit threaded transmission to the slider, and then can drive the slider to extend along the path of the clamping claw, thereby further increasing the clamping distance of the clamping claw and further improving applicability. By using Velcro to bond the anti-slip pad, the overall thickness of the subsequent bonding of the anti-slip pad can be kept parallel to the anti-slip pad on the clamping claw, thereby improving the clamping quality and facilitating disassembly. When the slider moves, the slider will drive the limit block to slide downward in the slide groove and the limit groove respectively, thereby providing multi-party limit and increasing stability.

[0026] Example

[0027] like Figure 1-Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient applicability of the existing device, and the overall idea is as follows:

[0028] In view of the problems existing in the prior art, the utility model provides a mechanical gripper for automation equipment, including a mechanical gripper body 11, a connecting rod group 12 is symmetrically arranged inside the mechanical gripper body 11, a clamping jaw 13 is arranged between each connecting rod group 12, a slide groove 14 is opened inside the two clamping jaws 13, and the inner walls of the two slide grooves 14 are symmetrically provided with a limiting groove 15;

[0029] Adjustment mechanisms are rotatably mounted inside the two slide slots 14;

[0030] The adjusting mechanism includes a screw rod 16, a driven bevel gear 17 is fixedly installed on the circumferential surface of the screw rod 16, a limiting block 18 is slidably installed inside each limiting groove 15, a slider 19 is fixedly installed between each group of limiting blocks 18, and the two sliders 19 are threadedly installed with the screw rod 16. The adjusting mechanism also includes Velcro 21, an anti-slip pad 22, a rotating shaft 24, an active bevel gear 25, and a slot 26. By inserting the end of the slot 26 into the slot 26 and rotating it, the rotating shaft 24 as a whole drives the active bevel gear 25 to rotate in the expansion slot 23 and the slide slot 14 respectively. At this time, the active bevel gear 25 will mesh with the driven bevel gear 17, so that the driven bevel gear 17 drives the screw rod 16 to rotate and transmit threaded transmission with the slider 19, and then the slider 19 can be driven to extend along the path of the clamping jaw 13, thereby further increasing the clamping spacing of the clamping jaw 13 and further improving the applicability.

[0031] The Velcro 21 is located on the side wall of the slider 19, and the Velcro 21 is fixed to the slider 19. The two anti-slip pads 22 are respectively located on the side wall of the Velcro 21 and the side wall of the clamping jaws 13. The anti-slip pads 22 on the two clamping jaws 13 are fixed to the clamping jaws 13. The anti-slip pads 22 on the two Velcros 21 are bonded to the Velcro 21. By using the Velcro 21 to bond the anti-slip pad 22, the overall thickness of the subsequent bonding of the anti-slip pad 22 can be kept parallel to the anti-slip pad 22 on the clamping jaw 13, thereby improving the clamping quality and facilitating disassembly.

[0032] An expansion slot 23 is provided through the inner wall of the two slide grooves 14, and two rotating shafts 24 are both located inside the expansion slots 23. The two rotating shafts 24 are rotatably installed with the expansion slots 23. The two active bevel gears 25 are both located on the circumferential surface of the side wall of the rotating shaft 24. The two active bevel gears 25 are both fixedly installed with the rotating shaft 24. The two active bevel gears 25 are both meshed and installed with the driven bevel gear 17. The two active bevel gears 25 are both located inside the slide groove 14. Two straight grooves 26 are both provided inside the rotating shaft 24. When the slider 19 moves, the slider 19 will drive the limit block 18 to slide downward in the slide groove 14 and the limit slot 15 respectively, thereby providing multi-directional limit and increasing stability.

[0033] Working principle:

[0034] In the first step, when the extension length of the clamping jaw 13 needs to be adjusted, the end of the screwdriver can be inserted into the slot 26 and rotated, so that the rotating shaft 24 as a whole drives the active bevel gear 25 to rotate in the expansion slot 23 and the slide slot 14 respectively. At this time, the active bevel gear 25 will mesh with the driven bevel gear 17, so that the driven bevel gear 17 drives the screw rod 16 to rotate and generate threaded transmission with the slider 19;

[0035] In the second step, the slider 19 will drive the limit block 18 to slide downward in the slide groove 14 and the limit groove 15 respectively. When the slider 19 is extended to a suitable position, the anti-slip pad 22 matched with the extended length of the slider 19 can be glued to the Velcro 21 (the other side wall of the anti-slip pad 22 connected to the Velcro 21 is provided with a pasted surface matched with the Velcro 21), and then the above steps can be repeated to adjust the other clamp 13.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
