Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically to a testing fixture for a generator. Background Technology

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, which converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and then transmits it to the generator, which then converts it into electrical energy. After the generator is developed, it usually needs to be tested. However, some generators are large in size, and when they need to be monitored, it may be necessary for many people to lift and move them to the testing device. During the movement, the generator may be bumped or knocked.

[0003] A search for the aforementioned issues revealed that, among the existing technologies, such as the mobile platform for generator testing disclosed in CN218703312U, the device involves installing threaded rods on both sides of a mobile plate, sliding a placement plate between the two threaded rods, and mounting several rotating cylinders on the placement plate. When testing the generator, the placement plate is lowered below the mobile plate, the generator is placed on it, and the generator can be rolled up using the rotating cylinders. Then, the mobile plate is raised again to move the generator up for testing. However, this device may cause bumps during movement, or the testing instruments may vibrate under the action of the motor during testing, causing the generator to shake, which may affect the testing process. Utility Model Content

[0004] This utility model proposes a testing fixture for generators, which solves the problem in the prior art that generators may cause bumps when moved, or that the testing instruments may cause vibrations under the action of the motor during testing, thus causing the generator to shake and potentially affecting the testing process.

[0005] The technical solution of this utility model is as follows:

[0006] A testing fixture for a generator includes a test bench, a movable plate, a support frame, a conveying assembly, a moving assembly, and a clamping assembly.

The conveying assembly is disposed on the test bench. The moving assembly is disposed on the support frame. The clamping assembly is disposed on the moving assembly.

[0007] Furthermore, the conveying assembly includes a conveying plate, conveying rollers, and a protective frame. The conveying plate is obliquely and fixedly installed on the side of the test bench, and the conveying plate has several grooves. Several conveying rollers are provided and are rotatably installed in the grooves of the conveying plate. The protective frame is fixedly installed on the conveying plate.

[0008] Furthermore, the moving component includes a support cover, a reciprocating screw, a screw nut, and a motor. The support cover is fixedly mounted on the support frame, the reciprocating screw is rotatably mounted inside the support cover, the screw nut is threadedly connected to the reciprocating screw, the motor is fixedly mounted on the support cover, and the output end of the motor is fixedly connected to the reciprocating screw.

[0009] Furthermore, the clamping assembly includes a connecting rod, a movable box, a clamping plate, and a limiting block. The connecting rod is fixedly mounted on the lead screw nut, and the movable box is fixedly mounted on the connecting rod. The movable box has a sliding groove, and the top of the movable box has several limiting through holes. The clamping plate is slidably mounted in the sliding groove of the movable box, and the top of the clamping plate has a limiting hole that matches the limiting through holes. The limiting block is adapted to the limiting through holes and the limiting holes.

[0010] Furthermore, it also includes a positioning component, which includes a fixing rod, a positioning cylinder one, and a positioning cylinder two. The fixing rod is fixedly installed on the support frame, the positioning cylinder one is fixedly installed on the fixing rod, and the positioning cylinder two is slidably installed inside the positioning cylinder one.

[0011] Furthermore, the first positioning cylinder and the second positioning cylinder are at the same horizontal position as the positioning hole on the moving plate, and the second positioning cylinder matches the positioning hole.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, by moving the generator on the conveyor roller, the generator can be conveyed to the top of the test platform, avoiding the need for manual lifting of it to the top of the test platform and preventing damage to the generator during the lifting process, which would affect subsequent testing;

[0014] 2. In this utility model, the clamping component can be moved closer to or further away from the generator by the movable component. The position of the clamping component and the generator can be adjusted according to the size of the generator, which avoids the difficulty of the clamping component clamping the generator when the generator is too large or too small.

[0015] 3. In this utility model, the generator can be clamped and fixed by the clamping component, which avoids the generator shaking during testing or movement.

[0016] In summary, through the cooperation of the test bench, moving plate, support frame, conveying assembly, moving assembly, and clamping assembly, this device can fix the generator during the testing and movement of the generator, thus avoiding inaccurate testing caused by the shaking of the generator.

The conveying component is set on the test bench 1, the moving component is set on the support frame 3, and the clamping component is set on the moving component.

[0026] In this embodiment, the conveying assembly includes a conveying plate 101, a conveying roller 102, and a protective frame 103. The conveying plate 101 is obliquely and fixedly installed on the side of the test bench 1, and a plurality of grooves are provided on the conveying plate 101. A plurality of conveying rollers 102 are provided, and the conveying rollers 102 are rotatably installed in the grooves of the conveying plate 101. The protective frame 103 is fixedly installed on the conveying plate 101.

[0027] In this embodiment, the moving component includes a support cover 201, a reciprocating screw 202, a screw nut 203, and a motor 204. The support cover 201 is fixedly mounted on the support frame 3. The reciprocating screw 202 is rotatably mounted inside the support cover 201.

The motor 204 is fixedly mounted on the support cover 201, and the output end of the motor 204 is fixedly connected to the reciprocating screw 202.

[0028] In this embodiment, the clamping assembly includes a connecting rod 301, a movable box 302, a clamping plate 303, and a limiting block 304. The connecting rod 301 is fixedly installed on the lead screw nut 203, and the movable box 302 is fixedly installed on the connecting rod 301. The movable box 302 has a sliding groove, and the top of the movable box 302 has several limiting through holes. The clamping plate 303 is slidably installed in the sliding groove of the movable box 302, and the top of the clamping plate 303 has a limiting hole that matches the limiting through hole. The limiting block 304 is adapted to the limiting through hole and the limiting hole.
