Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, specifically relating to a fixing clamp for testing the wear resistance of power fittings. Background Technology

[0002] Power fittings are metal accessories used to connect and assemble various devices in a power system, serving to transmit mechanical loads, electrical loads, and provide certain protective functions. Based on their function and structure, they can be categorized into suspension clamps, tension clamps, UT clamps, connecting fittings, splicing fittings, protective fittings, equipment clamps, T-clamps, busbar fittings, and guy wire fittings, among others. After production, power fittings require abrasion resistance testing. However, due to the irregular shapes of these fittings, the clamping stability is often insufficient, and they are not adaptable to different types of power fittings. Utility Model Content

[0008] Preferably, the built-in slide groove is provided with a limiting slide rail, and the threaded rod is fixedly provided with a slider that is slidably connected to the limiting slide rail.

[0009] Preferably, the outer wall of the fixed tube is connected to the drive structure.

[0010] The beneficial effects of this utility model are: simple structure, suitable for small power fittings, can clamp fittings in multiple ways, strong adaptability, and the clamping mechanism is driven by a screw, which can keep it fixed when the operation stops, making it highly practical, as detailed below:

[0011] (1) This utility model is equipped with clamping claws. When the clamping device clamps the power fittings, the clamping frame can be selectively installed. For flat power fittings, two clamping claws can be installed on the left and right sides. For cylindrical or hole-shaped power fittings, four circling clamping claws can be installed. The translation frame and the clamping frame are fixed by driving in fixing bolts. The clamping frame can be installed according to the specific size of the power fittings. The bending arm can be selected to be outward or inward, so as to adapt to more power fittings of different shapes.

[0012] (2) This utility model is provided with a threaded rod. When it is necessary to clamp the clamping claw, the motor drives the rotating column to rotate, which in turn drives the threaded rod to rotate. Under the twisting of the thread, the threaded rod moves along the threaded hole seat. When it moves, it drives the rotating seat to move. The rotating seat pulls the sliding frame to slide on the gathering cavity. When the sliding frame slides, the clamping claw connected to it opens or closes. After the clamping claw clamps the power fitting, the motor stops running. At this time, the pushing thread of the threaded rod is stuck on the threaded hole seat, which can maintain the clamping state of the clamping claw. Attached Figure Description

A circumferential array of sliding frames 5 is provided on the inner wall of the convergence cavity 3 via a slide rail. The sliding frames 5 slide on the convergence cavity 3, causing the clamp to clamp. The sliding frames 5 are detachably provided with clamping claws 9 via a support mechanism. Side rails 19 are fixed on both sides of the sliding frames 5. The sliding frame 5 is slidably connected to the receiving cavity 3, so that the sliding frame 5 slides against the receiving cavity 3.

The clamping claw 9 is integrally connected with the bending arm 8. Friction surfaces 10 are provided on both sides of the front end of the clamping claw 9.

[0024] See Figure 2-4 A motor 4 is fixedly installed at the rear end of the fixed tube 1. The output end of the motor 4 is connected to a rotating column 15 inserted into the fixed tube 1. The motor 4 drives the rotating column 15 to rotate. The rotating column 15 is slidably provided with a threaded rod 17 through an internal slide groove 16.

The rotating seat 13 pulls the sliding frame 5 to slide on the gathering cavity 3. When the sliding frame 5 slides, the clamping claw 9 connected to it opens or closes. After the clamping claw 9 clamps the power fitting, the motor 4 stops running. At this time, the push thread 21 of the threaded rod 17 is stuck on the threaded hole seat 18, maintaining the clamping state of the clamping claw 9.

[0027] Reference Figure 1-2 When the clamp is used to grip the power fittings, the clamping frame 7 can be selectively installed. For flat power fittings, two clamping claws 9 can be installed on the left and right sides. For cylindrical or hole-shaped power fittings, four circumferential clamping claws 9 can be installed. The translation frame 6 and the clamping frame 7 are fixed by driving in the fixing bolts 11. The clamping frame 7 can be installed according to the specific size of the power fitting.
