Description

Technical Field

[0001] This utility model belongs to the field of robotic arm technology, specifically relating to a robotic arm gripping device. Background Technology

[0002] Application number 202122163412.5 discloses a robotic arm gripping device. The output rod of an electric telescopic rod extends, and under the meshing action of a worm gear and a worm wheel, the worm wheel drives a second rotating rod to rotate. Under the linkage of the first rotating rod, the second rotating rod, and the rotating gripping rod, the two rotating gripping rods open. The robotic arm drives the gripping device to move to the position of the object to be gripped, so that the rotating gripping rods are positioned on both sides of the object. The output rod of the electric telescopic rod retracts, and under the meshing action of the worm gear and the worm wheel, the worm wheel drives the second rotating rod to rotate in the opposite direction. Under the linkage of the first rotating rod, the second rotating rod, and the rotating gripping rod... Under the action, the two rotating clamping rods retract, and the rotating clamping rods clamp the items. Compared with the traditional method of directly connecting the electric telescopic rod and the second rotating rod, this device adds a worm gear and worm structure at the connection point. Through the meshing of the worm gear and worm, the pushing force of the output rod of the electric telescopic rod is converted into the force that drives the worm to rotate, thereby completing the rotation of the second rotating rod. The amount of rotation is more controllable. This solves the problem that when the current clamping device for small items uses the linkage structure between the electric telescopic rod and the rod body to clamp the items, it is not easy to control the extension of the electric telescopic rod consistently, resulting in over-clamping or under-clamping. However, when the device moves the push plate outward via the electric telescopic rod, the worm gear drives the rotating rod to rotate outward through the worm wheel. Conversely, when the push plate moves inward, the rotating rod rotates inward to clamp the item. At this time, due to the push plate moving back, the item lacks the support of the push plate inside, and the clamping surface of the item is only the two clamping surfaces. The clamping stability is worse than that of three-sided clamping. Utility Model Content

The roller 6 is attached to the outer wall of the inclined plate 3. When the sliding member 2 moves, the rotating rod 4 is rotated through the inclined plate 3, so that the sliding member 2 and the two rotating rods 4 on both sides retract inward synchronously to grip the object.

[0014] As a preferred embodiment, a set of side baffles 7 are installed on the inner top of the outer shell 1, and a set of side baffles 12 are installed on the inner bottom of the outer shell 1. A sliding member 2 is slidably installed between the side baffles 7 and the side baffles 12. A motor 9 is installed on the inner top of the outer shell 1. One end of a screw 8 is installed at the output end of the motor 9, and the other end of the screw 8 is threaded with the sliding member 2. The motor 9 drives the screw 8 to rotate, so that the screw 8 drives the sliding member 2 to slide under the limitation of the side baffles 7 and the side baffles 12.

[0015] As a preferred embodiment, the bottom of the slider 2 extends out of the outer shell 1. A groove 13 is provided at the bottom of the slider 2. One end of a spring 14 is welded to the top of the inner side of the groove 13. One end of a slider 15 is installed at the other end of the spring 14. The other end of the slider 15 extends out of the groove 13 and is equipped with a push plate 16. The spring 14 drives the slider 15 to move outward, so that the push plate 16 fits tightly with the object.

[0016] As a preferred option, further, limit blocks 17 are symmetrically installed on both sides of slider 15, and limit grooves 18 are opened on both sides of slide groove 13. The limit blocks 17 are slidably installed in the limit grooves 18. By setting the limit blocks 17 and the limit grooves 18, the sliding distance of slider 15 is limited.

[0017] As a preferred embodiment, furthermore, a clamping plate 10 is installed at the bottom of the rotating rod 4. Slots are formed at opposite ends of both clamping plates 10. A fixing plate 11 is rotatably installed within the slots of the clamping plates 10. A mounting shell 19 is installed on the inner wall of the slots of the clamping plates 10. One end of a spring 20 is welded to the bottom inner side of the mounting shell 19. One end of a sliding plate 21 is installed at the other end of the spring 20. One end of a connecting block 22 is installed at the other end of the sliding plate 21. A rectangular slot 23 is formed on the side of the fixing plate 11 opposite to the mounting shell 19. A slide rod 24 is installed on the inner side of the groove 23. A slider 25 is slidably installed on the surface of the slide rod 24. A spring 3 26 is sleeved on the surface of the slide rod 24. The other end of the connecting block 1 22 is hinged to the opposite end of the slider 25. Buffer pads 27 are installed on the opposite ends of the two fixing plates 11. When the fixing plate 11 is in contact with the object, it rotates, causing the fixing plate 11 to press the connecting block 1 22 inward, causing the connecting block 1 22 to press the sliding plate 1 21 and the spring 20 inward. The slider 25 slides on the surface of the slide rod 24, pressing the spring 3 26, so that the fixing plate 11 is in close contact with the object.

[0018] As a preferred embodiment, furthermore, mounting shells 28 are installed on both inner walls of the outer shell 1. One end of spring 4 29 is welded to the bottom inner side of mounting shell 28. One end of sliding plate 2 30 is installed on the other end of spring 4 29. One end of connecting block 2 31 is installed on the other end of sliding plate 2 30. The other end of connecting block 2 31 extends out of mounting shell 28 and is rotatably mounted with roller 2 32. Roller 2 32 is in contact with one side of rotating rod 1 4. Spring 4 29 drives connecting block 2 31 and roller 2 32 to be in contact with rotating rod 1 4, so that roller 1 6 of rotating rod 1 4 is always in contact with inclined plate 3, which facilitates the movement of sliding component 2 to drive rotating rod 1 4 to rotate.

[0019] As a preferred embodiment, furthermore, one end of a rotating rod 33 is rotatably mounted on the top of both sides of the outer casing 1, and the other end of the rotating rod 33 is rotatably connected to one side of a rotating rod 4. A connector 34 is mounted on the top of the outer casing 1, and the connector 34 is used to connect to the equipment.

[0020] The outer casing, rotating rod, clamping plate, fixing plate, push plate, buffer pad, and motor in this case are existing technologies. The outer casing, rotating rod, clamping plate, fixing plate, push plate, and buffer pad are all the same structure and connection method as those in the prior art. The motor is a three-phase motor. As long as the outer casing, rotating rod, clamping plate, fixing plate, push plate, buffer pad, and motor meet the requirements of this case, they are all acceptable.

[0021] Working principle: The electrical components mentioned in this application are all connected to an external power supply and control switch during use. After the utility model is installed, first check the installation, fixation, and safety protection of the utility model, and then it can be used. During use, the motor 9 drives the screw 8 to rotate, and the screw 8 drives the slider 2 to slide under the limit of the side baffle. The movement of the slider 2 drives the inclined plate 3 to move. The roller 6 on the surface of the inclined plate 3 drives the rotating rod 4 to rotate around the rotating rod 5. The clamping plate 10 clamps the item through the fixed plate 11, and the slider 2 clamps the item through the push plate 16. The fixed plate 11 and the push plate 16 retract inward synchronously, so that the fixed plate 11 and the push plate 16 clamp the item on three sides, improving the clamping stability of the item.

[0022] When the fixing plate 11 clamps the item, the fixing plate 11 presses the connecting block 22 inward, causing the connecting block 22 to drive the sliding plate 21 to press the spring 20 inward. At the same time, the slider 25 slides on the surface of the sliding rod 24, causing the slider 25 to press the spring 36, so that the fixing plate 11 firmly clamps the surface of the item.

[0023] When the push plate 16 contacts the object, the push plate 16 drives the slider 15 to slide inward, compressing the spring 14 and making the push plate 16 firmly contact the object.

[0024] Roller 2 32 is attached to the side wall of rotating rod 1 4. Driven by spring 4 29, connecting block 2 31 drives roller 2 32 to fit tightly against rotating rod 1 4, so that rotating rod 1 4 fits tightly against inclined plate 3 through roller 1 6.
