Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts detection device, concretely is automobile front beam testing fixture. BACKGROUND

[0002] In the automobile body structure, the automobile front cross beam is a vital component. It spans the front end of the vehicle, like a bridge connecting the left and right front side members, and together with other body parts, it builds a stable body frame.

[0003] The front cross beam resists the vibration and impact brought by various complex road conditions during vehicle driving, ensuring the stability of the vehicle body. At the same time, when the vehicle encounters a collision, the front cross beam also plays a key role in dispersing and absorbing collision energy, which is crucial for protecting the safety of the passengers inside the vehicle. Therefore, it is particularly important to accurately detect it. For example, the dimensional deviation of the front cross beam may cause the connected components to be incorrectly installed, damaging the integrity of the vehicle body structure; hidden internal defects may cause structural failure during vehicle driving. Therefore, in order to ensure that the quality of the front cross beam meets strict standards, efficient and accurate detection is essential.

[0004] To meet the detection needs of the front cross beam, the prior art "a kind of automobile front cross beam testing fixture" (publication number: CN105588483A) discloses a detection device, which fixes the front cross beam and then sequentially passes through detection pins, marking seats, dial gauges, go-no-go gauges and other detection tools to realize various dimensional accuracy detection of the front cross beam, and uses the positioning holes on the mounting seat to realize the guidance of the detection tools, achieving the purpose of improving the detection convenience. However, the prior art still has the following technical problems:

[0005] Because the front cross beam is relatively long, there are many holes on the entire beam that need to be detected, and the detection method in the prior art needs to use detection tools to detect the holes on the front cross beam step by step, which is tedious, time-consuming and inefficient. UTILITY MODEL CONTENTS

[0006] The utility model provides automobile front beam testing fixture, can solve the detection device in prior art when detecting the multiple holes on front beam, needs to use detection tool to detect step by step, causes the detection process workload big, detects the problem of low efficiency.

[0007] The application provides the following technical scheme: a vehicle front beam testing fixture, comprising a testing table and a sliding testing unit located above the testing table; the sliding testing unit comprises sliding rails fixed on the testing table, sliding blocks slidingly connected to the sliding rails, a sliding plate fixed on the sliding blocks, and a plurality of support assemblies fixed above the sliding plate, the support assemblies being arranged along the length direction of the sliding plate; each support assembly comprises a support arm fixed on the sliding plate, a guide block fixed on the support arm, and a horizontal testing pin slidingly connected to the guide block, the testing end of the horizontal testing pin being provided with an annular limiting portion, and a compression spring being further sleeved on the rod portion of the horizontal testing pin and located between the annular limiting portion and the guide block.

The plurality of support assemblies are arranged on the sliding plate, and the horizontal testing pin is arranged on each support assembly. By moving the sliding plate, all the horizontal testing pins can be simultaneously moved close to the front beam and inserted into the holes on the front beam for precision detection. Therefore, the detection steps are greatly reduced. When the position precision of the holes on the front beam deviates and the horizontal testing pins cannot be inserted into the holes, the compression spring is compressed. By checking whether the compression spring is compressed, it can be determined which holes on the front beam have precision errors. Therefore, the holes with machining errors can be quickly identified, the rapid and convenient detection is achieved, and the detection efficiency is effectively improved.

Next, the flipping blocks 402 of the fixed testing unit 4 are sequentially adjusted to a horizontal position, aligning the vertical testing pins 404 on the testing block 403 with the testing position of the hole above the front beam 3. At this point, the hole above the front beam 3 can be precisely tested by sequentially pressing down the vertical testing pins 404. Push the slide plate 55 towards the front beam 3 using the handle 54, so that all the horizontal detection pins 62 move towards the front beam 3 simultaneously and are inserted into the holes on the front beam 3 for precision testing. Control the slide rail pin 53 to insert into the pin block 52 to lock the slide plate 55. At this time, it is possible to quickly check whether all the horizontal detection pins 62 are inserted into the holes on the front beam 3, so as to achieve rapid testing and improve the convenience and efficiency of testing. After the test is completed, reset the slide plate 55, the fixed detection unit 4 and the clamping unit 2 in sequence, and then remove the front beam 3.
