Description

Technical Field

[0001] This utility model relates to the field of withstand voltage testing technology, specifically a power module withstand voltage testing fixture. Background Technology

[0002] A withstand voltage test is a test in which a specified AC or DC high voltage is applied between the live and non-live parts of an electrical appliance to check the withstand voltage capability of the appliance's insulation material. The test checks whether the insulation performance of the product meets safety standards. Withstand voltage testers have high-speed and high-precision measurement performance and are widely used in the field of motors and electronics for withstand voltage testing. In the actual operation of a withstand voltage tester, a withstand voltage test fixture is an essential tool. Its operability and accuracy directly affect its accuracy. In current power supply withstand voltage testing, fixtures are required.

[0003] In the prior art, the fixtures used for power supply withstand voltage testing usually use a two-sided clamping method to hold and fix the power supply. This clamping method has good stability for normal power supplies, but the clamping effect is poor when clamping power supplies with irregular shapes, which can easily affect the withstand voltage test results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a power module withstand voltage test fixture, including a placement platform, and an auxiliary clamping mechanism is provided on the top of the placement platform;

[0006] The auxiliary clamping mechanism includes mounting blocks. Multiple evenly distributed sliding grooves are provided on the middle of the sidewalls of two sets of mounting blocks that are close to each other. A top rod is slidably connected to the inner side of each sliding groove. Limiting grooves are provided on both the front and rear walls of the inner side of each sliding groove. Limiting blocks are slidably connected to the inner side of each limiting groove. Each limiting block is fixedly connected to the front and rear walls of the top rod on the side away from the center of the placement platform. A bearing is provided at the end of each sliding groove away from the center of the placement platform. An adjusting knob is passed through and fixedly connected to the inner side of each bearing. A screw is fixedly connected to the end of each adjusting knob near the sliding groove. The screw is threaded into the inner side of the threaded groove.

[0007] As a preferred technical solution of this utility model, the threaded grooves are all set at the middle of the ends of the top rods on the left and right sides, and the front and rear sides, left and right ends of the placement platform are all provided with connecting grooves.

[0008] As a preferred embodiment of this utility model, each of the inner sides of the connecting groove is slidably connected to a connecting block, and each connecting block is fixedly connected to the front and rear sides of the middle part of the bottom wall of the mounting block.

[0009] As a preferred technical solution of this utility model, a movable plate is fixedly connected to the lower side of both the front and rear sets of connecting blocks, and the movable plate is fixedly connected to the output end of the bidirectional cylinder.

[0010] As a preferred embodiment of this utility model, the bidirectional cylinder is fixedly connected to the bottom of the fixing block, and the fixing block is fixedly connected to the middle of the bottom wall of the placement platform.

[0011] As a preferred embodiment of this utility model, the mounting blocks are all located on the left and right sides of the top of the placement platform, and the mounting blocks are all fitted with the placement platform with a clearance.

[0012] As a preferred embodiment of this utility model, the limiting blocks are all fitted with the limiting grooves with clearance, and the top rods are all fitted with the sliding grooves with clearance.

[0013] The beneficial effects of this utility model are:

[0014] 1. This power module withstand voltage test fixture, when the power module needs to be clamped, is placed in the middle of the placement platform and then the bidirectional cylinder is activated. During the operation of the bidirectional cylinder, the output end retracts, causing the two moving plates on both sides to move closer to each other. During the movement of the moving plates, the top mounting block moves closer to each other through the connecting block, thus clamping the inner power module.

[0015] 2. This power module withstand voltage test fixture, when clamping power supplies of different shapes, rotates the corresponding adjustment knob to rotate the screw. During the rotation of the screw, the push rod slides inside the slide groove, thereby changing the length of the push rod extending out of the slide groove. This allows the push rod to fit against the outer wall of the power module, making it easy to clamp and fix irregularly shaped power modules and improving the practicality of the fixture.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a power module withstand voltage test fixture, including a placement platform 1, and an auxiliary clamping mechanism 2 is provided on the top of the placement platform 1;

[0024] The auxiliary clamping mechanism 2 includes a mounting block 3. The auxiliary clamping mechanism 2 is provided on the inner side of the mounting block 3, which can better clamp and fix power supplies of different shapes. Multiple sets of evenly distributed sliding grooves 4 are provided on the middle of the side wall of the two sets of mounting blocks 3 that are close to each other. The inner side of each sliding groove 4 is slidably connected to a top rod 5. The top rod 5 can contact and fix with different points of the power supply. The front and rear walls of the inner side of the sliding groove 4 are provided with limit grooves 10. The inner side of each limit groove 10 is slidably connected to a limit block 9. The limit block 9 is fixedly connected to the front and rear walls of the top rod 5 on the side away from the middle of the placement platform 1. The limit block 9 and the limit groove 10 cooperate to restrict the top rod 5 and prevent it from rotating with the screw 8. The end of the sliding groove 4 away from the middle of the placement platform 1 is provided with a bearing 6. The inner side of each bearing 6 is connected to an adjustment knob 7 through and fixedly connected. The end of each adjustment knob 7 near the sliding groove 4 is fixedly connected to a screw 8. The screw 8 is threadedly connected to the inner side of the threaded groove 16.

[0025] Among them, the threaded grooves 16 are all set at the middle of the opposite end of the top rods 5 on the left and right sides. The front and rear sides, left and right ends of the placement platform 1 are all provided with connecting grooves 11, which provide space for the connecting block 12 to move.

[0026] In this device, connecting blocks 12 are slidably connected to the inner side of the connecting groove 11. The connecting blocks 12 are fixedly connected to the front and rear sides of the middle part of the bottom wall of the mounting block 3. The connecting blocks 12 serve to connect and fix the movable plate 13 and the mounting block 3.

[0027] Among them, a movable plate 13 is fixedly connected to the lower side of the two sets of connecting blocks 12. The movable plate 13 is fixedly connected to the output end of the bidirectional cylinder 14. During the operation of the bidirectional cylinder 14, the two movable plates 13 can move away from each other or move closer to each other.

[0028] The bidirectional cylinder 14 is fixedly connected to the bottom of the fixing block 15, and the fixing block 15 is fixedly connected to the middle of the bottom wall of the placement platform 1. The fixing block 15 serves to connect and fix the bidirectional cylinder 14 and the placement platform 1.

[0029] Among them, the mounting blocks 3 are all located on the top left and right sides of the placement platform 1, and the mounting blocks 3 are all fitted with the placement platform 1 with a clearance, and the mounting blocks 3 can slide left and right on the top of the placement platform 1.

[0030] Among them, the limiting blocks 9 are all in clearance fit with the limiting grooves 10, and the push rods 5 are all in clearance fit with the sliding grooves 4.

[0031] Working principle: When clamping the power supply is required, the power module is placed in the middle of the placement platform 1 and the bidirectional cylinder 14 is activated. During the operation of the bidirectional cylinder 14, the output end retracts, causing the two moving plates 13 to move closer to each other. During the movement of the moving plates 13, the top mounting block 3 is driven to move closer to each other through the connecting block 12, clamping the inner power module. When clamping power supplies of different shapes, the corresponding adjustment knob 7 is rotated to rotate the screw 8. During the rotation of the screw 8, the push rod 5 slides inside the slide groove 4, thereby changing the length of the push rod 5 extending out of the slide groove 4, so that the push rod 5 can fit against the outer wall of the power module, which is convenient for clamping and fixing irregularly shaped power modules and improves the applicability of the clamp.
