Description

Technical Field

[0001] This utility model relates to the field of pressure resistance testing technology, specifically a pressure resistance testing device. Background Technology

[0002] Withstand voltage testing generally refers to a voltage withstand test, which involves applying a specified AC or DC high voltage between the live and non-live parts (usually the casing) of an electrical appliance to check the insulation material's ability to withstand voltage. Withstand voltage testing tests the insulation performance of equipment under transient overvoltage by applying a high voltage several times the rated voltage. The combination of power frequency and DC testing ensures safety. Withstand voltage testing can detect potential insulation defects in advance and prevent electric shock caused by electrical gaps being broken down due to dust and moisture.

[0003] Before conducting a pressure test on a product, it is necessary to fix the product in place. However, the current methods for fixing products are generally to use a fixed bracket or a clamping frame. Fixed brackets can only support a single product, and clamping frames generally use clamping plates to hold the product in place. This is mainly for products with flat structures. However, when clamping some irregularly shaped products (such as aluminum housings for automobile engines), the flat clamping plates do not provide high stability, resulting in poor safety and stability of the product in place during the pressure test.

[0004] For example, the aforementioned problem exists in patent (CN223107961U); it describes "an aluminum substrate pressure resistance testing device, including an operating table, an aluminum substrate adjustment component, and a pressure resistance testing component, wherein the pressure resistance testing component includes a test frame, a first electrically adjustable telescopic rod is installed at the upper end of the test frame, a test head is installed at the lower end of the first electrically adjustable telescopic rod, the test head includes a mounting base, a pressure sensor is installed on the upper side of the mounting base, a magnetic head is provided on the lower side of the mounting base, an adsorption seat is provided on the outer side of the magnetic head, and a first mounting plate is provided on the lower side of the adsorption seat." This utility model... The design involves detecting images of an aluminum substrate using an image probe, automatically adjusting the test points on the aluminum substrate based on image analysis using an aluminum substrate adjustment component to improve test accuracy, disassembling the pressure-resistant test component using a limiting plate and pressure plate, and replacing the test probe using a magnetic head and adsorption seat to improve the convenience of test probe replacement. The design primarily utilizes a flat clamping plate within the aluminum substrate adjustment component to clamp and fix the product under test. However, when clamping irregularly shaped products (such as aluminum housings for automotive engines), the flat clamping plate offers low stability, resulting in poor safety and stability of the product under test during pressure resistance testing.

[0005] To address the aforementioned issues where clamping devices typically employ clamping plates to hold the product under test, and where planar clamping plates offer low stability when holding irregularly shaped products (such as aluminum housings for automotive engines), resulting in poor safety and stability of the product under test during pressure testing, we propose a pressure testing device. Utility Model Content

[0006] The purpose of this invention is to provide a pressure resistance testing device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pressure resistance testing device, including a test cabinet, a test frame inside the test cabinet, a support plate, a clamping frame on the top of the support plate, the clamping frame including two slidably symmetrically arranged clamping plates, a plurality of movably connected elastic clamping components on the outer wall of the clamping plate, the elastic clamping components including a push rod and a spring, one end of the spring being fixedly connected to one end of the push rod, the other end of the spring being fixedly connected to the clamping plate, and one end of the push rod extending through the clamping plate to the space between the two clamping plates.

[0008] Furthermore, the clamping plate has through holes on its surface that match the push rod, and the spring is sleeved on the outer wall of the push rod.

[0009] Furthermore, one end of the spring is fixedly connected to one end of the push rod via a fixed plate, and the other end of the spring is fixedly connected to the outer wall of the clamping plate via a guide ring, with the push rod sliding through the guide ring.

[0010] Furthermore, the test frame also includes a support frame and a front and rear transfer mechanism. The top of the outer wall of the support frame is horizontally provided with a left and right transfer mechanism. The outer wall of the moving output end of the left and right transfer mechanism is provided with an up and down transfer mechanism. The moving output end of the up and down transfer mechanism is provided with a test probe. The moving output end of the front and rear transfer mechanism is fixedly connected to the bottom of the support plate.

[0011] Furthermore, the test fixture also includes a sliding matching first guide rail and a first slider, the first guide rail being located below the support plate and the first slider being located at the bottom of the support plate.

[0012] Furthermore, the clamping plate has a base plate at its bottom, and the support plate has a gear rotatably connected between the two base plates at its top. The base plate has a rack horizontally positioned at its bottom that meshes with the gear, and the two racks are respectively located on both sides of the gear.

[0013] Furthermore, a servo motor is provided at the bottom of the support plate, and the output shaft of the servo motor is fixedly connected to a gear.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model comprises a test frame, a clamping frame, a clamping plate, an elastic clamping assembly, a push rod, and a spring. The clamping plate in the clamping frame clamps and fixes the product to be tested through the elastic clamping assembly. The push rod on the surface of the clamping plate moves towards the product to be tested along with the clamping plate. When the end of the push rod contacts the surface of the product to be tested, as the clamping plate continues to move, the end of the push rod presses against the surface of the product to be tested. As the clamping plate continues to move, the push rod pushes open and stretches the spring. The end of the push rod elastically expands and contracts according to the surface shape of the product to be tested, so that the push rod provides a wrap-around clamping and support for the product to be tested. This allows for adaptive clamping of the product to be tested, making it convenient for clamping and fixing products with irregular structures, and effectively ensuring the safety and stability of the product to be tested.

[0017] 2. In this utility model, the servo motor drives the gear to rotate, and the rotation of the gear can drive the rack to move horizontally. The rack drives the clamping plate to move horizontally through the base plate, so that the two clamping plates move simultaneously to realize the clamping and releasing operation of the clamping frame. The through holes on the surface of the clamping plate provide a channel for the push rod to move through and extend. The spring provides elastic extension and extension support for the push rod, the fixed plate ensures that the push rod can drive the spring to move in and out of extension after being subjected to force, and the guide ring provides guidance and support for the push rod to ensure the stability of the push rod.

One end of the spring 402 is fixedly connected to one end of the push rod 401, and the other end of the spring 402 is fixedly connected to the clamping plate 301. One end of the push rod 401 extends through the clamping plate 301 and between the two clamping plates 301.

[0028] In one embodiment, the test frame 2 further includes a support frame 202 and a front-rear transfer mechanism 203. A left-right transfer mechanism 204 is horizontally arranged on the top of the outer wall of the support frame 202. An upper-lower transfer mechanism 205 is arranged on the outer wall of the moving output end of the left-right transfer mechanism 204. A test probe 206 is arranged on the moving output end of the upper-lower transfer mechanism 205. The moving output end of the front-rear transfer mechanism 203 is fixedly connected to the bottom of the support plate 201. The front-rear transfer mechanism 203 can drive the support plate 201 to move back and forth, thereby driving the product to be tested on the support plate 201 to move back and forth. The support frame 202 controls the left-right transfer mechanism 204, the upper-lower transfer mechanism 205, and the test probe 206. The test probe 206 is supported in the air. The left and right transfer mechanism 204 adjusts the up and down transfer mechanism 205 left and right, thereby adjusting the left and right movement of the test probe 206. The up and down transfer mechanism 205 can drive the test probe 206 to move up and down, so that the test probe 206 can perform pressure resistance testing on different positions of the product under test. The front and rear transfer mechanism 203 can use an electric lead screw assembly for front and rear movement, or other linear drive mechanisms.

The clamping plate 301 in the clamping frame 3 clamps and fixes the product under test through the elastic clamping assembly 4. During clamping operations, both clamping plates 301 move simultaneously towards the center, and the elastic clamping assembly 4 moves with the clamping plates 301. The push rod on the surface of the clamping plate 301... As the clamping plate 301 moves toward the product to be tested, when the end of the push rod 401 contacts the surface of the product to be tested, as the clamping plate 301 continues to move, the end of the push rod 401 presses against the surface of the product to be tested. As the clamping plate 301 continues to move, the push rod 401 pushes open and stretches the spring 402. The end of the push rod 401 elastically expands and contracts according to the surface shape of the product to be tested, so that the push rod 401 provides a wrap-around clamping and support for the product to be tested. This allows for adaptive clamping of the product to be tested, making it convenient for clamping and fixing products with irregular structures, and effectively ensuring the safety and stability of the product to be tested.

[0035] In one embodiment, the bottom of the base plate 302 is provided with a second slider 303, and the top of the support plate 201 is provided with a second guide rail 304 that matches the second slider 303. When the base plate 302 is moved and adjusted, the second slider 303 at the bottom of the base plate 302 slides along the second guide rail 304, which can effectively improve the safety and stability of the movement adjustment of the base plate 302. The top rod 401 is parallel to the rack 306, and the second guide rail 304 is parallel to the rack 306, ensuring that the length direction of the top rod 401 is parallel to the moving direction of the clamping plate 301, so that the clamping of the product to be tested by the top rod 401 is more stable.

[0036] The working principle of this utility model:

[0037] Refer to the instruction manual appendix Figures 2-3 In this utility model, the base plate 302 supports the bottom of the clamping plate 301. The servo motor drives the gear 305 to rotate.
