Description

Technical Field

[0001] The utility model relates to the technical field of robot grippers, in particular to a robot gripper that is easy to maintain. Background Art

[0002] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. The fixture is usually composed of positioning elements, clamping devices, connecting elements and fixture bases. Among them, gripper fixtures are often required in some stacking operations of workpieces.

[0003] Publication No. CN214981116U discloses a robot clamp gripper, including a fixed plate, a rotating mechanism is arranged at the upper end of the fixed plate, a bidirectional threaded rod is arranged inside the fixed plate, a threaded connection block is arranged at one end of the bidirectional threaded rod, a clamp is arranged at the lower end of the threaded connection block, a telescopic rod is arranged at one side of the clamp, a protrusion is arranged at the other side of the clamp, and a support plate is arranged at one end of the telescopic rod. The robot clamp gripper can improve the clamping stability of irregular objects when clamping irregular objects by arranging the clamp, the bidirectional threaded rod, the threaded connection block, the protrusion, the reset spring, the slot, the support plate, the telescopic rod, the fixing hole and the positioning hole, which can effectively avoid the situation that the object is damaged due to the excessive clamping force, and improve the clamping efficiency of the gripper. At the same time, when clamping relatively square objects, it can effectively avoid the situation that the object slips due to wetness and slipperiness, and improve the safety of the gripper during use. Although the robot clamp gripper uses a motor to drive the clamping plates to move closer together to clamp the placed objects, it can effectively avoid slipping due to wet objects, avoid damage to the clamped objects, and improve safety in use. However, the gripper needs to be maintained regularly, otherwise it will affect the clamping effect. The robot clamp gripper is not easy to disassemble and is not convenient for staff to maintain, so it needs to be improved. Utility Model Content

[0028] Embodiment 2

[0029] See also Figure 5-6 A support plate 7 is provided on the surface of the splint 6, and a fixing hole 8 is opened on the surface of the support plate 7. Round sleeves 18 are fixedly installed on both sides of the splint 6, and a connecting rod 20 is provided on the surface of the round sleeve 18. A circular plate 17 is fixedly installed on the end of the connecting rod 20 close to the fixing hole 8, and a fixing column 16 is fixedly installed on the end of the circular plate 17 away from the connecting rod 20. A handle 21 is fixedly installed on the end of the connecting rod 20 away from the circular plate 17, and a spring B19 is sleeved on the surface of the connecting rod 20, which can fix the support plate 7 and the splint 6 together, and the specifications of the fixing hole 8 and the fixing column 16 match, and the fixing hole 8 and the fixing column 16 are slidingly connected.

[0030] Working principle: When clamping an object, first adjust the length of the support plate 7, pull the handle 21 to make the fixing column 16 leave the fixing hole 8, and then adjust the position of the support plate 7. After adjustment, release the handle 21, insert the fixing column 16 into the fixing hole 8 through the rebound force of the spring B19, fix the support plate 7 and the clamping plate 6 together, and then start the motor 3, the bidirectional threaded rod 10 rotates and drives the two connecting plates 5 to move in opposite directions or relative directions along the slide groove 9, and the connecting plate 5 drives the clamping plates 6 to close to each other. The gripper is used to clamp items. After using it for a period of time, the gripper needs to be maintained. Press the card block 14, and the card block 14 retracts into the interior of the connecting block 11, releasing the fixation of the splint 6. At this time, the splint 6 can be removed for maintenance. After maintenance, align the card slot 15 with the connecting block 11 and insert it. The card block 14 will shrink backwards under pressure, and when the splint 6 and the connecting plate 5 are attached together, the rebound force of the spring A12 can pop the card block 14 out of the connecting block 11, thereby fixing the splint 6 and the connecting plate 5 together.
