Description

Technical Field

[0001] The utility model relates to a track link size detection device, in particular to a track link position detection device. Background Art

[0002] The track links in bulldozer and excavator tracks are rotatable track links fixed to the tracks, similar to belt drives and chain drives in mechanical equipment. The most important structure of the track chain is the track link. The track link structure and dimensions are complex, and the track is designed as an integral structure. If the track link dimensions are abnormal, it will cause problems with the excavator's track operation, which may cause the entire chain to fail, making repair difficult and costly. Therefore, it is important to detect the position, size and structure of the track link during processing. It is necessary to ensure the product qualification rate by increasing the frequency of product measurement. However, the existing technology usually uses a square box clamp with a positioning bolt hole hanging plate installed on it. It is time-consuming and labor-intensive to hold the chain link with one hand to fix it, resulting in large measurement errors. After measurement, the measured dimensions need to be recorded and converted, which is time-consuming and inefficient. Therefore, the existing technology needs a track link detection device and a track link detection method that are easy to process, simple to clamp and fix, and only requires calibration when changing models, simple and quick to measure, and doubling the measurement efficiency.

[0003] Traditional measurement method: 1. Measure the diameters of the two bolt holes, measure the up, down, left, and right position dimensions of the bolt holes, and then convert them to get the center distance. 2. Measure the two diameters of the chain pin in the same way, measure the left and right position dimensions, and then convert them to get the pitch. 3. Use advance payment to fix the measurement of the up, down, left, and right position dimensions of the bolt holes and chain pin holes, and then calculate the measured data, compare and analyze the data with the standard dimensions, or perform a simple calculation on them. Products within the normal drawing range are qualified. Disadvantages: The measurement is relatively complicated and requires professional inspectors, there are many inspection dimensions, conversion is prone to errors, the cumulative error is large, and the efficiency is low. The present invention provides a rail chain link detection method and detection device, which greatly improves work efficiency compared to traditional measurements, can increase product detection frequency, and improve product qualification rate. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the present utility model is: a track link position detection device, comprising a bolt hole hanging plate and a pass / stop positioning plate;

[0006] The bolt hole hanging plate is grooved and fixed with a magnetic strip, and the bolt hole hanging plate is also provided with a plurality of bolt positioning pins, which are vertically distributed and located below the magnetic strip;

[0007] There are several bolt holes on the bolt hole hanging plate, and the bolt holes are used to fix the bolt hole hanging plate to the wall of the square box fixture through bolts. The square box fixture is a fixture with vertical and horizontal fixed at right angles, which is used to ensure the right angle between the working surface and the vertical surface.

[0008] A chain pin hole go / no-go gauge and a chain through hole go / no-go gauge are fixed to one side wall of the go / no-go gauge positioning plate. The go / no-go gauge positioning plate is also provided with a plurality of positioning holes for adjusting the installation distance between the chain pin hole go / no-go gauge and the chain through hole go / no-go gauge.

[0009] Furthermore, the bottom reference surface of the bolt hole hanging plate seamlessly coincides with the work surface.

[0010] Furthermore, a base is provided at the bottom end of the pass / stop positioning plate, and the bottom reference surface of the base seamlessly overlaps with the work surface.

[0011] The bolt hole hanging plate is fixed to the box fixture. The bolt locating pins and magnetic strips can be used to quickly fix the track link. The fixed positioning plate is used to move and measure the size and position of the holes on the track link. As can be seen from the above description of the structure of the utility model, compared with the existing technology, the utility model has the following advantages: compared with traditional measurement, it greatly improves work efficiency, can increase the frequency of product testing, and improves the product qualification rate.
