Description

Technical Field

[0001] The utility model relates to a mechanical detection technology, in particular to an adjustable benchmarking plate. Background Art

[0002] The tapered roller bearing assembly line is equipped with a parts inspection device before riveting and assembly, that is, an automatic inspection process for the outer dimensions of the inner and outer rings. The production line is equipped with an automatic inspection and benchmarking device. During the inspection, when X items are detected in the system or equipment, a benchmarking operation will be automatically performed to ensure measurement accuracy;

[0003] During the benchmarking test, it is necessary to use a benchmarking plate to push the benchmarking part for benchmarking. The benchmarking plate is set at one end of the push plate. The benchmarking plate is provided with a benchmarking groove that matches the benchmarking part. The benchmarking part is placed in the benchmarking groove on the benchmarking plate (the benchmarking part is a product that has been tested in advance). The benchmarking groove plays a positioning role for the benchmarking part to prevent misalignment when the benchmarking part moves, avoid collision between the benchmarking part and the probe and affect the accuracy of the benchmarking. The benchmarking plate and the benchmark in the groove are pushed to the bottom of the probe by the push plate, and the probe is used for benchmarking. Figure 3 and Figure 4 As shown in the figure; after alignment, the push plate drives the standard plate and the standard part to move away from the probe, and the undetected workpieces are taken and placed under the probe one by one by the manipulator for detection;

[0004] The size of the alignment groove on the existing alignment plate is fixed, and it can only be used to load matching matching parts. There are 5 alignment points on an assembly line (the five alignment points are: inner diameter size of the inner sleeve, inner raceway size, outer diameter of the outer sleeve, outer raceway of the outer sleeve, and assembly height alignment). The matching alignment plate must be replaced once the model is changed, which is inefficient. Utility Model Content

[0005] The utility model aims to provide an adjustable marking plate, which is an adjustable marking plate with simple structure, strong versatility and good adaptability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable marking plate, comprising a marking plate body, the marking plate body is a frame structure, two mutually corresponding clamping plates are arranged inside the frame of the marking plate body; two opposite frames of the marking plate body are respectively provided with slide grooves, and the two ends of the clamping plate are connected to the slide grooves by locking bolts; the two clamping plates are provided with mutually corresponding clamping grooves;

[0007] Preferably, the clamping groove is V-shaped, which makes the clamping stable and satisfies the clamping and fixation of different models.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The utility model can clamp and fix the marking part by adjusting the distance between the two clamping plates so that the inner sides of the two clamping grooves are in close contact with the marking part. When changing the model, there is no need to disassemble the entirety, only the locking bolt needs to be loosened, the distance between the two limit plates needs to be adjusted again, the new marking part can be put back in, and the clamping plates can be fixed with the locking bolt again, thus completing the model change. The marking plate has a simple structure and strong versatility, can meet the needs of loading marking parts of different models, has good adaptability, and improves efficiency.

[0017] Select the matching calibration plate body 1 according to the model of the calibration piece 8 to be loaded, and install the calibration plate body 1 on the pushing plate 6. Specifically, the calibration piece 8 is placed between the two clamping plates 2, and the distance between the two clamping plates 2 is adjusted by sliding, so that the inner side of the clamping groove 5 is in close contact with the calibration piece 8, and the clamping plate 2 is fixed with the locking bolt 4. The clamping groove 5 plays a positioning role for the calibration piece 8, avoiding the misalignment phenomenon when the calibration piece 8 moves, improving the detection accuracy of the calibration piece 8, and avoiding the collision between the calibration piece 8 and the probe 7;

[0018] The push plate 6 pushes the calibration plate body 1 to move, so that the calibration piece 8 moves to the bottom of the measuring head 7, and the measuring head 7 aligns the calibration piece 8; after the alignment, the push plate 6 pushes the calibration plate body 1 and the calibration piece 8 to move, so that the calibration piece 8 is away from the measuring head 7, and the untested products are taken and placed under the measuring head 7 one by one by the manipulator for inspection;

[0019] The two clamping plates 2 of the utility model are fixed to the slide groove 3 by the locking bolt 4. The locking bolt 4 can be loosened to adjust the distance between the two clamping plates 2, so that the two clamping plates 2 can meet the requirements of loading different types of standard parts 8, and have good adaptability.

[0020] The clamping groove 5 of the utility model is V-shaped, and the inner wall of the clamping groove 5 is in contact with the outer wall of the alignment piece 8 at four points. The clamping groove 5 can stably clamp the alignment piece 8, and the clamping groove 5 can meet the requirements of clamping and fixing alignment pieces 8 of different models.
