Description

Technical Field

[0001] The utility model belongs to the field of robots, and more specifically, relates to a robot variable-spacing framing fixture. Background Art

[0002] An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device widely used in the industrial field. It has a certain degree of automation and can rely on its own power source and control ability to achieve various industrial processing and manufacturing functions. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemical industry. The end of the robot often adopts a detachable structure to facilitate the replacement of different fixtures for grasping different parts.

[0003] In the existing robot fixture, during long-term use, the suction cup will cause the folding part to move through suction and deflation. Due to the stretching force, the folding part will be damaged and the suction force will become weaker. It is very easy for the object to fall due to insufficient suction force of the suction cup. The staff cannot quickly replace the damaged suction cup. The replacement space of the robot fixture is small, which is inconvenient for the staff to operate, thus affecting the normal use of the robot fixture and reducing the working efficiency of the robot.

[0027] Please refer to Figures 1-3 As shown, in this embodiment, a robot variable pitch framing jig is provided, which includes a jig main body 1. A transmission device is installed on the top of the jig main body 1, a slide rail 8 is installed on the bottom of the jig main body 1, a slider 9 is slidably fitted on the surface of the slide rail 8, a support rod 10 is installed at the bottom of the slider 9, and a fixing device 15 is installed inside the support rod 10;

[0028] The fixing device 15 includes a fixing component and a limiting component. The fixing component includes a plurality of mounting blocks 16. The mounting blocks 16 are installed on one side of the support rod 10. A first clamping groove 17 is opened inside the mounting block 16. A first spring 37 is installed inside the first clamping groove 17. A clamping rod 18 is slidably fitted inside the mounting block 16. A first limiting block 19 is installed at one end of the clamping rod 18. A first limiting groove 20 is opened inside the first limiting block 19. A connecting block 21 is installed on one side of the mounting block 16. A threaded groove 22 is opened inside the connecting block 21. A rotating bolt 23 is slidably fitted inside the connecting block 21. The rotating bolt 23 is clamped with the first limiting block 19 through the first limiting groove 20.

[0029] One application of this embodiment is as follows: When it is necessary to adjust the distance between the two support rods 10, the staff activates the cylinder 4. The output end of the cylinder 4 drives the fixed plate 5 to move. The movement of the fixed plate 5 drives one of the support rods 10 to move. The movement of one of the support rods 10 drives the first fixing block 12 and the first limiting rod 13 to move. The movement of the first limiting rod 13 drives the connecting plate 14 to move. The movement of the connecting plate 14 drives the other support rod 10 to move, so that the support rod 10 drives the slider 9 to move on the surface of the slide rail 8, thereby enabling the adjustment of the support rod 10. When the suction cup 11 at the bottom of the support rod 10 is damaged, the staff rotates the rotating bolt 23 so that the rotating bolt 23 disengages from the inside of the threaded groove 22. At this time, the staff pulls the rotating bolt 23. When the rotating bolt 23 disengages from the inside of the first limiting groove 20, the limitation on the first limiting block 19 can be released. Under the action of the first spring 37, the first limiting block 19 moves to drive the clamping rod 18 to move. When the clamping rod 18 disengages from the inside of the first clamping groove 26, the fixation of the sliding rod 25 can be released. The staff pulls the second fixing block 27 so that the movement of the second fixing block 27 drives the sliding rod 25 to move out of the inside of the sliding groove 24. The staff rotates the suction cup 11 so that the rotation of the suction cup 11 drives the threaded block 29 to rotate. When the threaded block 29 moves out of the inside of the installation groove 28, the disassembly of the suction cup 11 can be completed. When the sliding rod 25 moves out of the inside of the sliding groove 24, under the action of the second spring 35, the U-shaped rod 34 moves downward. When the clamping rod 18 moves to one side of the U-shaped rod 34, the limitation on the clamping rod 18 can be completed.

[0030] The limiting component of this embodiment includes a U-shaped rod 34. The U-shaped rod 34 is slidably fitted inside the support rod 10. A sliding groove 24 is formed inside the support rod 10. One end of the U-shaped rod 34 extends into the inside of the sliding groove 24, and the other end of the U-shaped rod 34 is in contact with the clamping rod 18. A second spring 35 is installed inside the support rod 10. One end of the second spring 35 close to the U-shaped rod 34 is fixedly connected to the U-shaped rod 34. Under the action of the second spring 35, the U-shaped rod 34 moves downward. When the clamping rod 18 moves to one side of the U-shaped rod 34, the limitation on the clamping rod 18 can be completed.

[0031] The transmission device of this embodiment includes a cylinder 4. An installation plate 3 is installed on the top of the fixture main body 1. The cylinder 4 is installed on the top of the fixture main body 1 through the installation plate 3. A fixed plate 5 is installed on one side of the cylinder 4. The fixed plate 5 is fixedly connected to the support rod 10. A first fixed block 12 is installed on the top of the support rod 10. A first limiting rod 13 is installed on the top of the first fixed block 12. A connecting plate 14 is slidably fitted between the two first limiting rods 13. A moving groove 38 is formed inside the connecting plate 14. The first limiting rod 13 is slidably fitted with the connecting plate 14 through the moving groove 38. The connecting plate 14 is installed at different positions between the two support rods 10. When the staff starts the cylinder 4, the output end of the cylinder 4 drives the fixed plate 5 to move. The movement of the fixed plate 5 drives one of the support rods 10 to move. The movement of one of the support rods 10 drives the first fixed block 12 and the first limiting rod 13 to move. The movement of the first limiting rod 13 drives the connecting plate 14 to move. The movement of the connecting plate 14 drives the other support rod 10 to move, so that the support rod 10 drives the slider 9 to move on the surface of the slide rail 8, thereby enabling the adjustment of the support rod 10.

[0032] A sliding rod 25 is slidably fitted inside the sliding groove 24 of this embodiment. A second clamping groove 26 is formed inside the sliding rod 25. The clamping rod 18 is clamped with the sliding rod 25 through the second clamping groove 26. A second fixed block 27 is installed at the bottom of the sliding rod 25. An installation groove 28 is formed inside the second fixed block 27. A threaded block 29 is in threaded fit inside the installation groove 28. A suction cup 11 is installed at the bottom of the threaded block 29. Air vent grooves 30 are formed inside the sliding rod 25, the second fixed block 27 and the threaded block 29. An air vent groove 31 is formed inside the support rod 10. The air vent groove 30 is communicated with the air vent groove 31. When the staff pulls the second fixed block 27, the movement of the second fixed block 27 drives the sliding rod 25 to move out of the inside of the sliding groove 24. The staff rotates the suction cup 11, so that the rotation of the suction cup 11 drives the threaded block 29 to rotate. When the threaded block 29 moves out of the inside of the installation groove 28, the disassembly of the suction cup 11 can be completed.
