[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figure 1-4 This utility model provides a fixture and robot for use, comprising a support frame 1, a connecting plate 2 fixedly connected to the support frame 1 for easy and secure installation of the connecting plate 2 to the end effector of the robot, a sliding block 4 movably connected through the support frame 1, a fixing block 5 fixedly connected to the support frame 1, a side plate 8 fixedly connected to the side of the support frame 1, a threaded adjusting rod 11 movably connected through the support frame 1, and multiple connecting bolts 3 fixedly connected to the connecting plate 2. The threaded adjusting rod 11 is used to drive the sliding block 4 to move.
[0025] Specifically, a rotary motor 9 is movably connected through the side of the side plate 8, and a first rotating wheel 14 is rotatably connected to the side of the rotary motor 9. A second rotating wheel 15 is fixedly connected to one end of the threaded adjusting rod 11. A pulley 10 is movably connected to the first rotating wheel 14 and the second rotating wheel 15. The first rotating wheel 14 drives the second rotating wheel 15 to rotate through the pulley 10, which in turn drives the threaded adjusting rod 11 to rotate.
[0026] Specifically, the lower end of the connecting plate 2 is fixedly connected to an extension block 23, and a second limiting groove 19 is provided in the extension block 23. A first limiting groove 17 is provided on the support frame 1. The two are used together to limit the movement of the threaded adjusting rod 11.
[0027] Specifically, a first limiting block 18 is fixedly connected to the threaded adjusting rod 11, and a second limiting block 20 is fixedly connected to the threaded adjusting rod 11. The first limiting block 18 is movably connected to the first limiting groove 17, and the second limiting block 20 is movably connected to the second limiting groove 19. Through the cooperation of the first limiting block 18 with the first limiting groove 17 and the second limiting block 20 with the second limiting groove 19, the rotation range of the threaded adjusting rod 11 can be limited, thus preventing the threaded adjusting rod 11 from deviating.
[0028] Specifically, the support frame 1 has a slide bar hole 12 symmetrical to the threaded adjustment rod 11. Multiple slide rods 13 are fixedly connected to both sides of the sliding block 4. The slide rods 13 are movably connected to the slide bar hole 12, which can ensure the stability of the sliding block 4 when it moves and prevent the sliding block 4 from tilting during the movement.
[0029] Specifically, a threaded bushing 16 is fixedly connected to the upper end of the sliding block 4. The threaded bushing 16 is movably connected to the threaded adjusting rod 11, which drives the sliding block 4 to move synchronously, thereby adjusting the position of the sliding block 4.
[0030] Specifically, the lower end of the sliding block 4 is provided with a first connecting groove 21, and the lower end of the sliding block 4 is movably connected to a sliding kneading claw 6. The upper end of the sliding kneading claw 6 is movably connected through the first connecting groove 21, so as to facilitate the replacement of different sliding kneading claws 6 according to the shape and size of the workpiece.
[0031] Specifically, the lower end of the fixed block 5 is provided with a second connecting groove 22, and the lower end of the fixed block 5 is movably connected to a fixed kneading claw 7. The upper end of the fixed kneading claw 7 is movably connected through the second connecting groove 22, which facilitates the replacement of the sliding kneading claw 6 and adapts to different workpieces.
[0032] Specifically, this includes robot 24, which performs operations such as grasping and transporting different workpieces.
[0033] Working principle:
[0034] The connecting plate 2 is fixed to the end of the robot using connecting bolts 3, and the support frame 1 serves as the foundation to support all components. The rotary motor 9 is started, which drives the first rotating wheel 14 to rotate. The first rotating wheel 14 drives the second rotating wheel 15 to rotate via the pulley 10, which in turn drives the threaded adjusting rod 11 to rotate. When the threaded adjusting rod 11 rotates, the threaded bushing 16 drives the sliding block 4 to move. The sliding rods 13 on both sides of the sliding block 4 slide along the sliding bar holes 12, ensuring stable movement. Simultaneously, the first limiting block 18 on the threaded adjusting rod 11 moves along the first limiting groove 17, and the second limiting block 20 moves along the second limiting groove 19, limiting the offset of the threaded adjusting rod 11. The movement of the sliding block 4 changes the distance between the sliding claw 6 and the fixed claw 7 on the fixed block 5. The sliding claw 6 can be replaced through the first connecting groove 21, and the fixed claw 7 can be replaced through the second connecting groove 22, thereby enabling the gripping of different workpieces.
[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
