Adjustable sample plate for backing plate marking-out

Abstract

The invention relates to the machining technology of railway track equipment, and aims to provide an adjustable sample plate for backing plate marking-out. The adjustable sample plate comprises a sample plate body with a central hollow square frame-shaped structure, wherein slideways are arranged on frames at the two sides of a hollowed-out part correspondingly, the positioning plate and the at least one leaning ruler are arranged on the sliding ways at the two sides, the end parts of a locating plate and at least one guiding rule are arranged on the slideways on both sides, the supporting rule and the locating plate are both adjustably and fixedly arranged on the slideways; and a locating hole is formed in one end of the sample plate body, and the locating plate is arranged at the other end of the sample plate body and is provided with the locating hole. According to the adjustable sample plate, the marking-out operation on various backing plates can be realized through the guiding rule and the locating plate which are adjustably arranged, and various types of backing plates can be applicable to the maximum degree, so that waste of sample making materials in the application rangeis greatly reduced, and the production cost is saved; the manufacturing period and the application period of the sample plate is shortened, and the production efficiency is improved; and the problemsof various types and large number of old sample plates are solved, the pressure of an enterprise storing the sample plate is reduced, and the maintenance cost is lowered.

Description

Technical field [0001] The invention relates to the processing technology of railway track equipment, in particular to an adjustable backing plate template for scribing a backing plate. Background technique [0002] The backing plate is a key part of the railway system. During the processing of the backing plate, the table plate, iron seat, shoulder and other components need to be welded at a specific position. In order to ensure the welding accuracy, the bottom plate will be marked in advance during the production process to determine Position of welding. Therefore, it is necessary to use a template for marking different welding positions, different welding angles, and different hole distances of the same width backing plate. [0003] The template used in the prior art for scribing the backing board is such as figure 2 As shown, it is a rectangular material whose size is basically the same as that of the backing plate. Positioning holes and marking frames are made on the template...

AI Technical Summary

Problems solved by technology

However, in actual production, due to the diversification of backing plate models due to technological development, the probability of repeated occurrence of backing plates of the same size is not high

This also leads to more and more samples for scribing, which not only increases the cost of manufacturing samples, but also makes it more and more difficult to store and classify samples
