Description

Technical Field

[0001] The utility model relates to the technical field of wear test equipment, in particular to a wear test device for electric hardware. Background Art

[0002] In the power system, power fittings are key components, and their performance stability and durability are crucial to the normal operation of the power system.

[0003] In order to ensure the quality of electrical fittings, a series of tests are usually carried out before they are put on the market, including an assessment of their wear resistance.

[0004] Although the existing electrical fitting wear test device can achieve the purpose of wear test to a certain extent, there are some problems in the test process, especially the inconvenience of adjusting the position of the electrical fitting, which leads to the incompleteness and inaccuracy of the wear test.

[0005] Specifically, existing electrical fittings wear test devices often use a fixed installation method, which makes it inconvenient to adjust the position of the electrical fittings, resulting in an incomplete wear test. This means that during the test, the wear condition of the electrical fittings may not truly reflect their actual conditions in use, and the obtained wear test results may not accurately reflect the true performance of the electrical fittings.

[0006] In view of this, this application is hereby filed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: an electric hardware wear test device, comprising a test bench 1 and a reciprocating assembly mounted thereon for controlling the displacement of a cable, an angle adjustment frame 2 rotatably mounted on the test bench 1, a clamping assembly for fixing the electric hardware is arranged inside the angle adjustment frame 2, an adjusting screw 9 for adjusting the vertical displacement of the clamping assembly is threadedly connected on the top wall of the angle adjustment frame 2, the clamping assembly comprises a sliding frame 3 symmetrically slidably mounted inside the angle adjustment frame 2, two bidirectional screw rods 5 are rotatably mounted on the two sliding frames 3, a clamping arm 4 is threadedly connected on the bidirectional screw rod 5, the bottom end of the adjusting screw 9 is rotatably connected to the top surface of the sliding frame 3, and the bottom wall of the angle adjustment frame 2 is threadedly connected to the bottom wall of the angle adjustment frame 2. A sector gear 10 is fixedly installed, and an electric push rod 11 is fixedly installed inside the test bench 1. A transmission rack 12 meshing with the sector gear 10 is fixedly installed at the telescopic end of the electric push rod 11. The clamping assembly as a whole can be driven to vertically displace along the inner wall of the angle adjustment frame 2 by rotating the adjusting screw 9. The transmission rack 12 can be driven to displace by telescoping the electric push rod 11. The transmission rack 12 drives the sector gear 10 meshing with it to rotate. The sector gear 10 drives the angle adjustment frame 2 to rotate, and then drives the clamping assembly to adjust the angle. The position of the clamping assembly can be adjusted by adjusting the position of the electric hardware fixed inside the clamping assembly, thereby improving the comprehensiveness of the wear test.

[0023] See also Figure 1 The reciprocating assembly includes a fixed seat 14 fixedly mounted on the top surface of the test bench 1 and a sliding seat 15 slidably mounted on the top surface of the test bench 1. The fixed seat 14 and the sliding seat 15 are arranged opposite to each other, and both the fixed seat 14 and the sliding seat 15 are provided with through holes for the cable to pass through. The fixed seat 14 and the sliding seat 15 are both threadedly connected with positioning bolts passing through the through holes. A cylinder 16 for pushing the sliding seat 15 to linearly move is fixedly mounted on the top of the test bench 1. When it is necessary to perform a wear test on the electric hardware fixed on the clamping assembly, the cable end is held and passed through the through hole on the fixed seat 14, and then the cable is passed through the electric hardware and the through hole on the sliding seat 15, and the cable is fixed between the fixed seat 14 and the sliding seat 15 by tightening the positioning bolt. During the wear test, the sliding seat 15 is controlled to move back and forth by the cylinder 16. During the displacement of the sliding seat 15, the cable is driven to move synchronously, thereby causing wear between the cable and the electric hardware during the wear test.

[0024] See also Figure 4 A clamping pad 13 is fixedly installed on the inner wall of the clamping arm 4. The material of the clamping pad 13 is rubber, and the outer surface of the clamping pad 13 is integrally formed with anti-slip patterns. The arrangement of the clamping pad 13 can improve the stability of the clamping assembly in clamping and fixing the power fitting.

[0025] See also Figure 4 A straight slot is provided on the side wall of the angle adjustment frame 2 for the bidirectional screw rod 5 to pass through, and the end of the bidirectional screw rod 5 passes through the straight slot. The straight slot allows the clamping assembly to slide vertically along the angle adjustment frame 2, and at the same time, it can also improve the stability of the clamping assembly during vertical sliding.

[0026] See also Figure 4 The outer ends of the two bidirectional screw rods 5 passing through the straight slot are fixedly installed with synchronous wheels 6, and a synchronous belt 7 is installed between the two synchronous wheels 6. A knob 8 is fixedly installed on the end of one of the bidirectional screw rods 5. When the power hardware needs to be clamped and fixed, the knob 8 is turned. Under the transmission cooperation of the synchronous wheel 6 and the synchronous belt 7, the two bidirectional screw rods 5 can rotate synchronously, and then the upper and lower parts of the two clamping arms 4 can be synchronously displaced relative to each other, thereby improving the stability of the clamping arms 4 during relative displacement.

[0027] Working principle: When in use, place the power fitting between the two clamping arms 4, turn the knob 8, and the two bidirectional screws 5 can be rotated synchronously under the transmission cooperation of the synchronous wheel 6 and the synchronous belt 7, so that the upper and lower parts of the two clamping arms 4 can be synchronously displaced relative to each other to clamp and fix the power fitting. Then, the operator holds the cable end and passes it through the through hole on the fixed seat 14, then passes the cable through the power fitting and through the through hole on the sliding seat 15, and fixes the cable between the fixed seat 14 and the sliding seat 15 by tightening the positioning bolt. During the wear test, the sliding seat 15 is controlled to reciprocate by the cylinder 16 Displacement, the sliding seat 15 drives the cable to move synchronously during displacement, thereby causing wear between the cable and the power fittings during the wear test. By rotating the adjusting screw 9, the clamping assembly as a whole can be driven to move vertically along the inner wall of the angle adjustment frame 2. The electric push rod 11 can be extended and retracted to drive the transmission rack 12 to move. The transmission rack 12 drives the fan gear 10 meshing with it to rotate, and the fan gear 10 drives the angle adjustment frame 2 to rotate, thereby driving the clamping assembly to adjust the angle. By adjusting the position of the clamping assembly, the position of the power fittings fixed inside the clamping assembly can be adjusted, thereby improving the comprehensiveness of the wear test.
