Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to a high-precision testing device. Background Technology

[0002] In the automotive manufacturing industry, the car seat frame, as the core support structure of the seat, directly affects the safety, comfort, and lifespan of the seat, thus impacting the overall quality and market competitiveness of the vehicle. Car seat frames are typically assembled from various metal tubing and sheet metal through welding, riveting, and other processes. Their complex structure and high precision requirements mean that even minor dimensional deviations or structural defects can lead to serious problems such as loosening, abnormal noises, or even breakage during use, threatening the safety of passengers.

[0003] Currently, the inspection of car seat frames mainly relies on traditional manual inspection. Manual inspection depends primarily on the experience and visual observation of the inspectors. This method is not only inefficient, but also easily affected by various factors such as the inspector's subjectivity, fatigue level, and ambient lighting, making it difficult to guarantee the accuracy and consistency of the inspection results.

[0004] Therefore, it is necessary to invent a high-precision detection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision detection device to solve the problems in the above-mentioned technology.

The top of the base plate is also provided with an auxiliary pressing component, a top hole position detection component, a side hole position detection component, a contour detection component, and a gap detection component. The auxiliary pressing component and the gap detection component are both located on one side of the support reference, and the top hole position detection component, the side hole position detection component, and the contour detection component are all located on the other side of the support reference.

[0007] By integrating multiple functional modules such as top hole position detection component, side hole position detection component, contour detection component and gap detection component, it is possible to accurately detect multiple key parts of the product under test.

[0008] Preferably, the auxiliary clamping assembly includes a first column fixedly installed on the top of the base plate, and a quick clamp for clamping the product to be tested is fixedly installed on the top of the first column.

[0009] The quick clamp in the auxiliary clamping assembly can quickly and firmly clamp the product to be tested, preventing the product from moving or shifting during the testing process, thereby ensuring the stability and accuracy of the test.

[0010] Preferably, the top hole position detection component includes a uniform positioning seat fixedly installed on the top of the base plate, and a top hole position detection pin is inserted into the top of the uniform positioning seat. The uniform positioning seat is used for uniformly inserting and placing the top hole position detection pin when not in use.

[0011] The unified positioning seat in the top hole position measurement component provides a unified placement location for the top hole position measurement pin, which facilitates the management and retrieval of the pin and avoids random placement and loss of the pin.

One end of the first spring is fixedly connected to the surface of the carrier plate, and the other end of the first spring is fixedly connected to the tail end of the first pin.

[0015] By using a manual translation stage and pin number one, the side hole position detection plug can be moved to detect the side hole position. At the same time, the design of spring number one acts as a buffer, improving the flexibility and safety of operation.

[0016] Preferably, the contour detection component includes a second column fixedly installed on the top of the base plate. A second pin, which can slide back and forth, is provided through the top of the second column.

[0019] The elastic buckle can lock the grip handle of the detection probe, making it easy to pick up and put back the detection probe.

[0020] Preferably, a temporary positioning seat is also fixedly installed on the top of the base plate. The temporary positioning seat is set near the top hole position detection socket of the support reference. The temporary positioning seat is used for temporary insertion and placement of the top hole position detection pin during use.

[0021] The temporary positioning seat is used to temporarily place the top hole position detection pin, which facilitates quick access to the top hole position detection pin during continuous testing.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. By integrating multiple detection components, such as top hole position detection component, side hole position detection component, contour detection component and gap detection component, multiple key parts of the product under test can be accurately detected. This integrated design significantly reduces the errors and subjectivity that may occur during manual inspection, thereby greatly improving the accuracy and consistency of the inspection.

[0024] 2. By setting up temporary positioning seats and unified positioning seats, the temporary positioning seats are used to temporarily place the top hole position detection pins, which facilitates quick access to the top hole position detection pins. The unified positioning seats are used to return the top hole position detection pins to their original positions after the detection is completed, thereby maintaining the overall neatness of the device and facilitating subsequent unified management.

The top of the support reference 2 has a top hole position detection socket 201 that matches the opening on the top of the product under test. The hole position detection pin 402 can pass through the top opening of the product under test and be inserted into the top hole position detection pin 201. The side hole position detection assembly 5 includes a manual translation stage 501 fixedly installed on the top of the base plate 1. A carrier plate 502 is installed at the moving end of the manual translation stage 501. A first pin 503 that can slide back and forth is provided through the middle of the carrier plate 502. A side hole position detection plug 504 that matches the side opening of the product under test is installed at the head end of the first pin 503. A first spring 505 is sleeved on the surface of the first pin 503. One end of the first spring 505 is fixed to the surface of the carrier plate 502. The connection is as follows: the other end of spring 505 is fixedly connected to the tail end of pin 503; the contour detection component 6 includes a second column 601 fixedly installed on the top of the base plate 1; a second pin 602 that can slide back and forth is provided through the top of the second column 601; a contour detection block 603 matching the side contour of the product to be tested is installed at the head end of the second pin 602; a second spring 604 is sleeved on the surface of the second pin 602; one end of the second spring 604 is fixedly connected to the surface of the second column 601; and the other end of the second spring 604 is fixedly connected to the tail end of the second pin 602; the gap detection component 7 includes a fixed...

There is a gap between the support reference 2 and the bending part of the product under test. The detection probe 702 is used to detect the size of the gap to determine whether it is qualified. A temporary positioning seat 8 is also fixedly installed on the top of the base plate 1. The temporary positioning seat 8 is set near the top hole position detection insertion hole 201 of the support reference 2. The temporary positioning seat 8 is used for temporary insertion and placement of the top hole position detection pin 402 during use.

[0041] The quick clamp 302 and manual translation stage 501 mentioned above are existing technology products, and their specific structures and functions will not be described in detail here.

[0042] Working principle of this utility model:

[0043] Refer to the instruction manual appendix Figure 1-11When using this utility model, firstly, the product to be tested is placed stably on the support reference 2 on the top of the base plate. Then, the product to be tested is clamped and fixed using the auxiliary clamping assembly 3. The quick clamp 302 applies an appropriate clamping force to the product to be tested, so that it is firmly fixed on the support reference 2, preventing movement or displacement during subsequent testing, thereby ensuring the accuracy of the test.

[0044] Remove the top hole position detection pin 402 from the unified positioning seat 401. Pass the top hole position detection pin 402 through the top opening of the product under test and try to insert it into the top hole position detection socket 201 on the top of the support reference 2. Observe the insertion of the pin. If the pin can be inserted smoothly without obvious looseness, it means that the top hole position of the product under test meets the design requirements. If the pin is difficult to insert or is obviously loose after insertion, it means that there is a deviation in the top hole position.

[0045] Adjust the position of the carrier plate 502 using the manual translation stage 501, so that the side hole position detection plug 504 at the head of the first pin 503 is close to and attempted to be inserted into the side opening of the product under test. Observe the insertion of the side hole position detection plug 504. If the side hole position detection plug 504 can be inserted smoothly, it indicates that the side hole position is qualified; if the side hole position detection plug 504 is blocked from insertion, it indicates that the side hole position does not meet the requirements.

[0046] Push the second pin 602 to gradually bring the contour detection block 603 closer to and attempt to contact the side contour of the product under test. Observe the movement of the second pin 602 and the degree of contact between the contour detection block 603 and the side contour of the product under test. If the contour detection block 603 can fit tightly with the side contour of the product under test and the second pin 602 moves smoothly, it indicates that the side contour meets the design requirements. If there is a loose fit or the pin movement is obstructed, it indicates that there is a deviation in the side contour.

[0047] Remove the test probe 702 from the elastic buckle 701, hold the handle 703, and try to insert the tip of the test probe 702 into the gap between the support reference 2 and the bend of the product to be tested. If the test probe 702 can be smoothly inserted into the gap and there is no looseness after insertion, it means that the gap size meets the requirements. If the test probe 702 is difficult to insert or does not fit tightly after insertion, it means that the gap size does not meet the design requirements.

[0048] After completing the inspection of the current product, before inspecting the subsequent products, the operator needs to remove and put back all the inspection tools and remove the current product. Among them, the top hole position detection pin 402 can be temporarily inserted into the corresponding temporary positioning seat 8 after being removed. Since the temporary positioning seat 8 is set close to the top hole position detection pin 201 at the top of the support reference 2, it is convenient to quickly use the top hole position detection pin 402 during subsequent inspections.

[0049] After all products have been tested, the operators must return each testing tool to its proper place according to regulations. At this time, the top hole position detection pin 402 must be inserted back into the corresponding unified positioning seat 401 to keep the device in good order and facilitate subsequent unified management.
