However, when clamping the objects, the objects are generally clamped on the upper surface of the workbench, and some surfaces are blocked during the clamping process, thereby reducing the surfaces that can be grinded by the robot arm. Sometimes, in order to complete the grinding, the user needs to change the clamping position of the object many times, which wastes time and affects work efficiency. In order to solve this technical problem, the utility model proposes a grinding robot arm for a grinder. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, a grinding robot arm for a grinder includes a workbench 1, a slide groove 2 is opened inside the workbench 1, the inner wall of the slide groove 2 is slidably connected to a limit block 3, the inner wall of the slide groove 2 is relatively smooth, and the limit block 3 is subject to less friction when moving in the slide groove 2.

[0025] The outer surface of the limit block 3 is fixedly connected to the support plate 4, and the inside of the support plate 4 is slidably connected to the cross plate 5. The limit block 3 will fix the position of the support plate 4, and the limit block 3 cannot be detached from the slide groove 2, thereby limiting the position of the support plate 4. The support plate 4 will limit the direction in which the cross plate 5 can move, thereby avoiding deviation in the moving position of the cross plate 5.

[0026] A power mechanism 6 is provided inside the support plate 4, and a threaded rod 7 is connected to the inside of the cross plate 5 by a thread. A sliding rod 8 is rotatably connected to the inside of the threaded rod 7 and can move when the threaded rod 7 rotates. When the threaded rod 7 moves, the sliding rod 8 moves with it. The sliding rod 8 can rotate inside the threaded rod 7 but cannot be pulled out of the threaded rod 7.

[0027] One end of the slide bar 8 is fixedly connected to a splint 9, and the interior of the cross plate 5 is rotatably connected to a rotating rod 10. The slide bar 8 will fix the position of the splint 9. When the slide bar 8 moves, it will move with the splint 9. The other cross plate 5 will limit the position of the rotating rod 10, so that the rotating rod 10 can only rotate but not move.

[0028] A spring 11 is fixedly connected to the inside of the rotating rod 10, and a gear 12 is slidably connected to the inside of the rotating rod 10. A limiting mechanism 13 is arranged inside the support plate 4. The rotating rod 10 will fix the position of the spring 11. The rotating rod 10 can limit the direction in which the gear 12 can move, so that the gear 12 cannot rotate alone. A sleeve is arranged on the outer surface of the gear 12 for facilitating its pulling.

[0029] The power mechanism 6 includes a transmission plate 601, the outer surface of the transmission plate 601 is slidably connected to the inside of the support plate 4, the upper surface of the transmission plate 601 is fixedly connected to the bottom surface of the cross plate 5, the support plate 4 will limit the position to which the transmission plate 601 can move, thereby avoiding deviation in the position of the transmission plate 601, the transmission plate 601 will fix the position of the cross plate 5, and will move with the cross plate 5 when the transmission plate 601 moves.

[0030] The outer surface of the transmission plate 601 is slidably connected to the limit frame 602, and the outer surface of the limit frame 602 is slidably connected to the inside of the workbench 1. When the limit frame 602 moves up and down, it will move with the transmission plate 601, and the workbench 1 will limit the position to which the limit frame 602 can move.

[0031] The bottom surface of the limiting frame 602 is fixedly connected with a cylinder 603 , which is installed inside the workbench 1 . The workbench 1 can fix the position of the cylinder 603 , and when the cylinder 603 is started, the limiting frame 602 can be moved upward.

[0032] The limiting mechanism 13 includes a transmission rod 1301, the outer surface of which is slidably connected to the inside of the support plate 4, and one end of the transmission rod 1301 is fixedly connected to a chuck 1302. The support plate 4 limits the direction in which the transmission rod 1301 can move, thereby avoiding deviation in the position of the transmission rod 1301. When the transmission rod 1301 moves, it will move with the chuck 1302.

[0033] The outer surface of the chuck 1302 is engaged with the interior of the workbench 1, and a spring 2 1303 is fixedly connected to the outer surface of the chuck 1302. The end of the spring 2 1303 away from the chuck 1302 is fixedly connected to the outer surface of the support plate 4. The position of the chuck 1302 is limited by the engagement of the workbench 1 and the chuck 1302, so that the transmission rod 1301 cannot move along the workbench 1. The spring 2 1303 is used to provide thrust for the chuck 1302, so that the chuck 1302 can engage with the workbench 1 when not subject to external force, and the support plate 4 will fix the position of the spring 2 1303.

[0034] The outer surface of the support plate 4 is slidably connected to the outer surface of the workbench 1, and the end of the spring 11 away from the rotating rod 10 is fixedly connected to the outer surface of the gear 12. One end of the rotating rod 10 is fixedly connected to the outer surface of the splint 9. The spring 11 can provide thrust for the gear 12. When the rotating rod 10 rotates, it can rotate with another splint 9. The outer surface of the splint 9 is relatively rough, and other objects are not easy to slide from the surface of the splint 9.

[0035] The outer surface of the gear 12 is slidably connected to the outer surface of the horizontal plate 5. The outer surface of the workbench 1 is installed with a mechanical arm body 14. When the gear 12 is inserted into the horizontal plate 5, the rotating rod 10 cannot rotate. A handle is installed at one end of the rotating rod 10, which can facilitate the user to rotate the rotating rod 10.

[0036] Working principle: When using the device, first start the cylinder 603 to move the limit frame 602. The movement of the limit frame 602 will move the transmission plate 601. The movement of the transmission plate 601 will move the cross plate 5 to a suitable position. Then pull the transmission rod 1301 outward to separate the chuck 1302 from the workbench 1. Then move the support plate 4. The movement of the support plate 4 will move the slide bar 8, the clamping plate 9 and the rotating rod 10. After the two clamping plates 9 move to a suitable position, release the transmission rod 1301. 01, spring two 1303 will push the chuck 1302 to re-engage with the workbench 1, and then put the object between the two clamps 9, and rotate the threaded rod 7 to make the clamps 9 clamp the object, then start the robot arm body 14 to grind the object. When the direction of the object needs to be changed, the gear 12 can be pulled out from the horizontal plate 5, and then the rotating rod 10 can be rotated to make the clamps 9 rotate with the object and the slide bar 8. After adjustment, release the gear 12, and the spring one 11 will push the gear 12 to insert into the horizontal plate 5.
