The invention has the advantages that: 1, the sample plate can be used in the offset distance range of 0 to 90mm, and the adjusting process is simple; 2, the sample plate has small volume and light weight and is fixed reliably, so the sample plate is convenient to carry in the using process; and 3, the sample plate can achieve a multi-purpose effect, so convenience is brought to the management of sample plates in a workshop.

Description

Adjustable top bow sample plate for steel rails

Technical field

The present invention relates to a kind ofly can adjust flexibly according to the production and application requirement, fixing reliable, again can be in 0～90mm scope adjustable supporting apart from, satisfy existing track switch product rail spare Production requirement, realize with the many adjustable top bow sample plate for steel rails of a generation, be mainly used in the bending process control such as rail spare, plate, to improve production quality and production efficiency, realization is with the many functions of a generation, reduce the model manufacturing cost, facilitated simultaneously the management of model, belonged to field of measuring technique.

Background technology

Production scale constantly enlarges in enterprise, and product category increases, and for satisfying the requirement of production duration and the quality of production, just must make special-purpose auxiliary detection instrument comes the production control quality, enhances productivity simultaneously.Produce ranks at track switch, in the process of the rail spares such as tongue, heart rail, wing rail, in order to satisfy the requirement of rail spare line style, need to be with rail spare bending certain angle.Usually in the process of basketry file, respectively bend the offset distance value according to rail spare in drawing, convert and make the bending model of 1.2 meters of length, so that production and application.Because product category is many, need to make large batch of bending model, cause using and manage not convenient.

Summary of the invention

Purpose of design: avoid the weak point in background technology, design a kind ofly can require to adjust flexibly according to production and application, fixing reliable, again can be in 0～90mm scope adjustable supporting apart from, satisfy existing track switch product rail spare Production requirement, realize with the many adjustable top bow sample plate for steel rails of a generation.

Design proposal: in order to realize above-mentioned purpose of design.This detection model can be used for the bending of all kinds of rail spares in track switch to be used.In rail spare bending process, take the bending model as with reference to the bending of rail spare.

Detection method: this detection model is a kind of auxiliary detection frock, is mainly used in the site operation process, to the control of rail bending angle, with this improve production efficiency and product quality.When rail spare is carried out bending, use have certain bending angle model as a reference, take the inflection point as the summit, contrast both registrations, judge whether to reach bending angle with this.

Operation steps is as follows:

The first step, according to the requirement of product construction drawing and technical papers, adjust offset distance value h, as shown in Figure 2;

Second step, as shown in Figure 1 utilizes nut 1-2 and 1-3, and being fixed becomes the bending model with certain angle;

The 3rd step, take the bending model as reference, use bending lathe bending rail.

This programme is in design process, and mainly consider from following several respects: the first, model length is 1.2 meters, and can be bent into multiple angles from midpoint; The second, after being bent into certain angle, can be fixed, no longer rotate around central point; Three, material rigidity wants large, avoids being out of shape in the process of using; Four, volume is little, quality is light.

Technical scheme: adjustable top bow sample plate for steel rails, two check-out consoles connect by bearing pin, can rotate around bearing pin and adjust the offset distance value, and fastening by double nut detects models with two and fixes.The key position of present design is locking device, because two check-out consoles are elongate in shape, has the larger arm of force after connecting.For can either be around center coupling shaft rotation, and reliable lock.Select the friction force locking mode in design, designed otic placode on check-out console B, enlarge active surface, simultaneously also form certain arm of force, processed arc groove on check-out console A, by the snap-in force of fastening screw order I, II, make between otic placode and check-out console A and produce friction force, reach fixing purpose.

The present invention compares with background technology, and the one, can satisfy offset distance model within 0～90mm scope and use, adjustment process is simple; The 2nd,, quality little because of its volume is light, fixing reliable, and be easy to carry in the process of using; The 3rd, owing to can realizing having brought facility for the management of workshop model with the many effects of a generation.

Embodiment

Embodiment 1: with reference to accompanying drawing 1-3.Adjustable top-bending sample plate outside drawing as shown in Figure 1, two check-out consoles connect by bearing pin, and adjust the offset distance value around its rotation, fastening by double nut detects models with two and fixes.

Embodiment 2: on the basis of embodiment 1, a kind of detection method of adjustable top bow sample plate for steel rails is characterized in that: this detection model is a kind of auxiliary detection frock, is mainly used in the site operation process, control to the rail bending angle, with this improve production efficiency and product quality, when rail spare is carried out bending, use have certain bending angle model as a reference, take the inflection point as the summit, contrast both registrations, judge whether to reach bending angle with this, operation steps is as follows:

The first step, according to the requirement of product construction drawing and technical papers, adjust offset distance value h, as shown in Figure 2;

Second step, as shown in Figure 1 utilizes nut 1-2 and 1-3, and being fixed becomes the bending model with certain angle;
