Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, in particular to a manipulator clamp which is anti-clamping damage. Background Art

[0002] The manipulator clamp is a part of the robot arm, which is used to clamp, grab, operate and process objects in automation and robot applications. Announcement No. CN215968836U announces a manipulator clamp, including a clamp housing, a drive mechanism and a clamping mechanism. The clamp housing is provided with a drive mechanism, and two fixed plates are provided on the drive mechanism. The left surface of the fixed plate is provided with a fixed groove, and the two fixed grooves are provided with a clamping mechanism. The clamp housing is connected to the two fixed plates and the two clamping mechanisms by fastening nuts; this practical and effective solution solves the problem that the existing manipulator clamp cannot fully contact the surface of the clamped object when clamping the object on the inclined surface, so that the object cannot be stably clamped during the clamping process, and the object is easy to fall. However, the clamp is not provided with an anti-clamping damage mechanism, which makes it easy for the clamp to clamp the object when clamping the object, thereby reducing the protective effect of the object when being clamped. The clamp still has shortcomings and needs to be improved. Utility Model Content

[0033] The protective pad 9 improves the protective effect when the object is clamped, thereby effectively preventing the clamping plate 5 from easily damaging the object. At the same time, when the protective pad 9 is damaged and needs to be disassembled and replaced, the two sets of slide plates 15 can be pushed toward the fixed plate 12 at the same time. In the process of pushing the slide plate 15, the slide plate 15 will slide on the outer wall of the cylinder 13 and the inside of the fixed frame 11. In the process of sliding, the slide plate 15 will compress the spring 14 toward the fixed plate 12. After being compressed for a certain distance, the limit column 16 will move away from the limit hole 10. After moving away, the plug block 8 is pushed again, so that the plug block 8 slides inside the slot 7. After sliding a certain distance, the plug block 8 and the damaged protective pad 9 can be removed for replacement, thereby improving the replacement efficiency of the damaged protective pad 9 and facilitating the operation of the operator.

[0034] In another embodiment, the limiting rod 6 is slidably connected to the clamping plate 5, and the anti-deflection effect of the clamping plate 5 during adjustment is improved through the sliding connection.

[0035] In another embodiment, the slide plate 15 is slidably connected to the fixing frame 11 , and the limiting column 16 is slidably connected to the limiting hole 10 . The fixing effect of the protective pad 9 is improved by the slidably connecting between the limiting column 16 and the limiting hole 10 .

[0036] In another embodiment, one end of the spring 14 is fixedly connected to the fixed plate 12, and the other end of the spring 14 is fixedly connected to the slide plate 15, and the use effect of the spring 14 is improved by the fixed connection.

[0037] In another embodiment, connecting plates 21 are fixedly installed on both sides of the housing 1, and mounting holes 22 are symmetrically opened through the surface of the connecting plates 21, so that the fixture as a whole can be conveniently fixed to other equipment through the mounting holes 22.

[0038] In another embodiment, a rotating shaft 17 is installed inside the shell 1, and a gear 18 is fixedly installed on the top of the rotating shaft 17. A motor 2 19 is fixedly installed on the inner surface of the shell 1, and a gear 2 20 is fixedly installed on the output end of the motor 2 19. By starting the motor 2 19, the gear 2 20 is driven to rotate. During the rotation process, the gear 2 20 will drive the gear 1 18 to rotate. During the rotation process, the gear 1 18 will drive the rotating shaft 17 to rotate inside the shell 1. During the rotation process, the rotating shaft 17 will drive the frame 2 and the clamped object to rotate, thereby improving the angle adjustment effect of the clamped object, and effectively avoiding the need to remove the object and re-clamp it when adjusting the processing angle of the object.

[0039] In another embodiment, gear 2 20 and gear 1 18 are meshed with each other, the rotating shaft 17 is connected to the housing 1 through a bearing, and the bottom end of the rotating shaft 17 is fixedly connected to the frame 2. The rotation effect of the rotating shaft 17 is improved by the mutual meshing and bearing connection.

[0040] Working principle: when in use, first put the object in the middle of the two groups of clamping plates 5, and then start the motor 3 after placing it. When the motor 3 is working, it will drive the bidirectional screw 4 to rotate. During the rotation process, the bidirectional screw 4 will drive the two groups of clamping plates 5 to slide on the outer wall of the limit rod 6 toward the location of the object. After sliding a certain distance, the two groups of clamping plates 5 will clamp and fix the object. In the process of clamping and fixing the object, the protective pads 9 installed on the inner sides of the two groups of clamping plates 5 will protect the object, thereby effectively preventing the clamping plates 5 from easily damaging the object, thereby improving the protective effect when the object is clamped. At the same time, when the protective pads 9 are damaged When disassembly and replacement are required, the two sets of slides 15 can be pushed toward the location of the fixed plate 12 at the same time. In the process of pushing the slide 15, the slide 15 will slide on the outer wall of the cylinder 13 and the inside of the fixed frame 11. In the process of sliding, the slide 15 will compress the spring 14 toward the location of the fixed plate 12. After being compressed for a certain distance, the limit column 16 will move away from the limit hole 10. After moving away, the plug block 8 is pushed again to make the plug block 8 slide inside the slot 7. After sliding for a certain distance, the plug block 8 and the damaged protective pad 9 can be removed for replacement, thereby improving the replacement efficiency of the damaged protective pad 9 and facilitating the operation of the operator. When the processing angle of the object needs to be adjusted, the motor 2 19 can be started, and the motor 2 19 can drive the gear 2 20 to rotate. The gear 2 20 will drive the gear 1 18 to rotate during the rotation. The gear 1 18 will drive the rotating shaft 17 to rotate inside the shell 1 during the rotation. The rotating shaft 17 will drive the frame 2 and the clamped object to rotate during the rotation, thereby improving the angle adjustment effect of the clamped object, and effectively avoiding the need to remove the object and re-clamp it when adjusting the processing angle of the object.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
