Description

A testing device for automotive water pump pulleys Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a testing device for automotive water pump pulleys. Background Technology

[0002] The water pump pulley is used to drive the water pump impeller and is one of the core components of the water pump. Before the water pump pulley is produced, the height of the center tooth of the pulley needs to be tested to ensure that the water pump pulley can rotate stably. The existing method for testing the height and runout of the water pump pulley is to first use an auxiliary fixture to position the product, then use a height gauge to measure the height of the pulley, and use a magnetic dial indicator to measure the axial and radial runout of the pulley. However, this method leads to unstable test results. The dial indicator is installed in a fixed position to test the pulley height and axial runout. The fixed fixture form can only test a single dimension and cannot achieve multi-dimensional inspection. It cannot effectively cope with the complex application scenarios in the production process. Moreover, the dial indicator needs to be recalibrated for each test, resulting in large differences in test results between water pumps in the same batch. The test process has a significant impact on the results and the operation is cumbersome. Therefore, this technical solution is proposed to improve the method. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies in the detection of automobile pulleys, which involve large differences and cumbersome processes, and to provide an automobile water pump pulley detection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for automotive water pump pulleys, comprising a support platform, a slide table slidably disposed on the upper part of the support platform, a positioning pin for fixing the pulley body disposed on the upper surface of the slide table, a mounting frame disposed on one side of the support platform, a testing instrument disposed on the mounting frame, and a clamping device for pressing the pulley body disposed on the side of the slide table.

[0005] Furthermore, the upper part of the support platform is provided with a guide rail, and the lower part of the slide table is provided with a slider that cooperates with the guide rail.

[0006] Furthermore, a fixing plate is provided on the side of the support platform, and a push rod is provided on the side of the fixing plate. The end of the push rod is connected to the side of the slide table, and the end of the push rod is provided with a screw for adjusting the length.

[0007] Furthermore, the testing instrument is a dial indicator, and dial indicators are provided on the upper part and the side of the mounting bracket.

[0008] Furthermore, the clamping device includes a connecting seat disposed on the slide table, a pressing strip is hinged to the upper part of the connecting seat, a pressing rod is hinged to the upper part of the pressing strip, an adjusting rod is disposed at the end of the pressing strip, and a pressing joint is disposed at the bottom of the adjusting rod that abuts against the pulley body.

[0009] The beneficial effects of this utility model embodiment are as follows: The upper and lower parts of the mounting frame are detachable and connected by bolts, allowing the position of the dial indicator to be changed according to the pulley body at different positions, thus improving applicability. By setting dial indicators at different positions on the mounting frame, the height and runout of different parts of the pulley can be detected, effectively solving the problem that traditional fixed inspection fixtures can only detect a single size. It can adapt to complex application scenarios in the production process, realize multi-size inspection, and reduce inspection costs. The push rod passes through the fixed plate, and the other end of the push rod is provided with a handle. The push rod can be extended or retracted by swinging the handle. The other end of the push rod is connected to the side of the slide table. The top of the push rod is also provided with a screw for adjusting the length.

[0014] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] Referring to Figures 1 to 3, this utility model embodiment discloses an automotive water pump pulley testing device, mainly including a support platform 1, a slide 2, a positioning pin, a mounting bracket 3, testing instruments, and a clamping device. The support platform 1 serves as the basic support structure of the entire device, and a guide rail 101 is provided on its upper part. The guide rail 101 provides guidance for the sliding of the slide 2. The slide 2 can slide smoothly on the support platform 1 through a slider 102 provided at the lower part that cooperates with the guide rail 101. A positioning pin is provided on the upper surface of the slide 2. The positioning pin is used to fix the pulley body 4, ensuring that the pulley maintains a stable position during the testing process. The positioning pin is detachable, and different hole positions can be selected for positioning according to different models of pulley bodies 4, improving the use effect and convenience in the testing process.

[0016] A mounting frame 3 is provided on one side of the support platform 1. A testing instrument, namely a dial indicator 301, is installed on the mounting frame 3. To meet different testing needs, dial indicators 301 are provided on the upper and side of the mounting frame 3. The upper and lower parts of the mounting frame 3 are detachable and connected by bolts. The position of the dial indicator 301 can be changed according to the different positions of the pulley body 4, thereby improving applicability. By setting dial indicators 301 at different positions on the mounting frame 3, the height and runout of different parts of the pulley can be detected. This effectively solves the problem that traditional fixed inspection tools can only detect a single size. It can adapt to complex application scenarios in the production process, realize multi-size inspection, and reduce testing costs.

[0017] To facilitate the movement of the slide table 2, a fixed plate 5 is provided on the side of the support platform 1. A push rod 501 is installed on the side of the fixed plate 5, passing through the fixed plate 5. A handle 502 is provided at the other end of the push rod 501. By swinging the handle 502, the push rod 501 can be extended or retracted. The other end of the push rod 501 is connected to the side of the slide table 2. A screw for adjusting the length is also provided at the top of the push rod 501. By rotating the screw, the length of the push rod 501 can be finely adjusted, changing the forward sliding distance of the slide table 2. This achieves precise control of the sliding distance of the slide table 2, allowing the pulley to move accurately to the detection position, ensuring the detection results of the dial indicator 301. Furthermore, in the same batch of tests, the position of the dial indicator 301 does not need to be changed, improving detection efficiency.

[0018] A clamping device is provided on the side of the slide table 2 to clamp the pulley body 4 and prevent it from shaking during the testing process. The clamping device includes a connecting seat 201 on the slide table 2. A pressing strip 202 is hinged to the upper part of the connecting seat 201, and a pressing rod 203 is hinged to the upper part of the pressing strip 202. By operating the pressing rod 203, the pressing strip 202 can be rotated around the connecting seat 201. An adjusting rod 205 is provided at the end of the pressing strip 202, and a pressing head that abuts against the pulley body 4 is provided at the bottom of the adjusting rod 205. During the clamping process, the length of the adjusting rod 205 can be adjusted according to the actual size of the pulley to make the pressing head fit tightly against the pulley body 4, ensuring that the pulley is firmly clamped.

[0019] In the actual testing process, the pulley body 4 to be tested is first placed on the slide table 2 and fixed in position using a positioning pin to complete the initial positioning. Then, the clamping device is operated, and the pressing rod 203 drives the pressing strip 202 to rotate, so that the pressing joint abuts against the pulley body 4. The length of the adjusting rod 205 is adjusted to firmly press the pulley body 4. Next, the push rod 501 is pushed, so that the slide table 2 slides along the guide rail 101, moving the pulley to the testing position. At this time, the dial indicator 301 on the mounting bracket 3 can detect the center tooth height, axial and radial runout of the pulley. Because the dial indicator 301 is flexibly installed, it can realize comprehensive testing of different parts of the pulley, and there is no need to recalibrate the dial indicator 301 for each test, which effectively reduces the difference in test results between pumps in the same batch and improves the stability and accuracy of the test. After the inspection is completed, the clamping device is released, and the inspected pulley is removed so that the next pulley can be inspected. This achieves accurate and efficient inspection of water pump pulleys, and features simple operation, stable test results, and the ability to perform multi-dimensional inspection, which can effectively improve production efficiency and product quality.
