Problems solved by technology

[0002] At present, for the turnout products of high-speed railway and urban rail transit in China, tape measure or ordinary caliper is mainly used in the process of measuring the machining size of its spacer iron parts. The measuring tools have poor adaptability and low work efficiency. The quality of the product cannot be effectively controlled, and the stability and accuracy are not reliable. In the final assembly process, there are often contour mismatches and dimension out-of-tolerance, which seriously affect the assembly efficiency.

Embodiment Construction

[0024] like figure 1 As shown, the switch interval iron detection ruler of the present invention includes a main ruler 1 , a vernier ruler 2 , a left measuring claw 3 and a right measuring claw 4 .

[0025] The main ruler 1 is a rectangular strip structure, and two rows of main ruler scales are symmetrically arranged on the front upper side and the front lower side along the length direction.

[0026] The vernier scale 2 is slidingly fitted with the main scale 1, and it includes a rectangular base 21 and a rectangular measuring portion 22 connected to the middle of one end of the base; the upper and lower sides of the front of the measuring portion 22 are symmetrically fixed with a pair of upper and lower sides by screws. Symmetrically arranged slideways spaced apart from each other, the measuring part 22 is connected to the main scale 1 through a sliding fit through the upper and lower slideways, and the outer walls of the upper and lower slideways of the measuring part 22 ar...

Abstract

The invention relates to a track switch filler detection ruler which comprise a main ruler and a vernier scale assembled on the main ruler. The detection ruler further comprises left and right measuring claws; the left measuring claw is detachably assembled in the head end of the main ruler, and a left clamping groove matching the contour of one end of a filler is formed in one end, opposite to the head end of the main ruler, of the left measuring claw; and the right measuring claw is detachably assembled on the vernier scale, and a right clamping groove matching the contour of the opposite end of the filler is formed in the end of the end, facing the left clamping groove, of the right measuring claw. The track switch filler detection ruler is simple in structural design, rapid, convenientand precise in measurement, and can be used to measure the filler spacing accurately in the manufacturing and assembling process of track switch filler components of high-speed railway and urban railway.

Description

technical field [0001] The invention relates to a detection ruler, in particular to a switch interval iron detection ruler. Background technique [0002] At present, for the turnout products of high-speed railway and urban rail transit in China, tape measure or ordinary caliper is mainly used in the process of measuring the machining size of its spacer iron parts. The measuring tools have poor adaptability and low work efficiency. The quality of the product cannot be effectively controlled, and its stability and accuracy are unreliable. In the final assembly process, there are often contour mismatches and out-of-tolerance dimensions, which seriously affect the assembly efficiency. Spacer iron is an important part of turnout products. It is generally a cast or welded structural part. It must be precisely processed before assembly. Its main function is to connect various types of rails as a whole. At the same time, in order to ensure the safety of train crossings, The backoff...
