Description

Technical Field

[0001] The utility model relates to the technical field of manipulator maintenance, in particular to a fixing device for manipulator maintenance. Background Art

[0002] A manipulator is an automatic device that can imitate certain movements of human hands and arms and is used to grab, move objects or operate tools according to a fixed procedure. Its characteristic is that it can be programmed to complete various expected tasks, and its structure and performance combine the advantages of both human and mechanical machines.

[0003] After searching, a Chinese patent with publication number CN213946179U discloses a fixing device for repairing a manipulator. The technical point is that it solves the problem that there are many existing fixing devices, but most of these fixing devices are inconvenient to use, and the cost is too high. They cannot be adjusted according to the mechanical parts that need to be repaired, which brings unnecessary trouble to the operators.

[0004] However, during the implementation of the above scheme, when it is necessary to repair the remaining positions of the manipulator after clamping, the manipulator needs to be disassembled and clamped again to change the repair position. The operation is cumbersome and it is not convenient to adjust the angle of the manipulator after clamping. Therefore, it is not convenient to repair different positions of the manipulator and has low applicability.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the disadvantages of being inconvenient to repair different positions of the manipulator and having low applicability.

[0007] The utility model discloses a fixing device for repairing a manipulator, comprising a worm and two fixing parts, wherein the outer surface of the worm is meshed with a worm wheel, the inner wall of the worm wheel is fixedly connected with a rotating shaft, the inner wall of each of the fixing parts is provided with an annular groove, the inner wall of each of the annular grooves is slidably connected with an annular part, the inner wall of each of the annular parts is fixedly connected with a connecting part, the right side surface of one of the connecting parts is fixedly connected with the left end of the rotating shaft, and each of the connecting parts is fixedly connected with a clamping part on a side close to each other.

[0008] Furthermore, a sliding block is fixedly connected to the bottom surface of each of the fixing members, and a supporting block is fixedly connected to the right side surface of one of the sliding blocks.

[0009] Furthermore, the inner wall of the support block is rotatably connected to the outer surface of the worm, and a support platform is provided below the worm.

[0010] Furthermore, two sliding grooves are provided on the upper surface of the support platform, and the inner wall of each sliding groove is slidably connected to the outer surface of the corresponding sliding block.

[0011] Furthermore, the left side and right side of the support platform are both fixedly connected to support frames, the right side of one of the support frames is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to a bidirectional threaded rod.

[0012] Furthermore, the other end of the bidirectional threaded rod is rotatably connected to the left side surface of the corresponding support frame, the outer surface of the bidirectional threaded rod is rotatably connected to the inner wall of the support platform, and the inner wall of each sliding block is threadedly connected to the outer surface of the bidirectional threaded rod.

[0013] Furthermore, the bottom surface of the support platform is fixedly connected with threaded barrels arranged at equal distances, and the inner wall of each threaded barrel is threadedly connected with a threaded base.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model is provided with components such as a worm, a worm wheel, a connecting piece, and a clamping piece. When the two clamping pieces clamp the manipulator, the worm is rotated to engage with the worm wheel to achieve the rotation effect of the worm wheel. The worm wheel drives the connecting piece to rotate through the rotating shaft, and the connecting piece is limited by the annular piece and the annular groove. At this time, the connecting piece drives the clamping piece to rotate, and the two clamping pieces clamp the manipulator to achieve the effect of synchronous rotation of the two clamping pieces, thereby achieving the effect that the device can adjust the angle of the manipulator after clamping, which is convenient for maintenance of different positions of the manipulator and improves the applicability of the device.

[0016] 2. The utility model places the manipulator between the two clamping parts by setting up clamping parts, sliding blocks, bidirectional threaded rods, motors and other components, and drives the bidirectional threaded rods to rotate through the motor. At this time, the two sliding blocks are driven to move relative to each other through the threaded connection between the bidirectional threaded rods and the corresponding sliding blocks. The sliding grooves are opened on the surface of the support platform, and the sliding grooves and the sliding blocks are set as sliding connections to achieve a limiting effect on the sliding blocks. At this time, the two sliding blocks drive the corresponding clamping parts to clamp the manipulator, thereby achieving the effect that the device can achieve the relative movement of the two clamping parts to clamp the manipulator, and the setting of the threaded barrel and the threaded base can achieve the effect of adjusting the height of the support platform, and the height of the threaded base can be adjusted according to the placement surfaces with different flatnesses, thereby improving the practicality of the device.
