Abstract

The utility model relates to a fixture for the full welding of a brake beam. The fixture includes a base; a stand column is arranged on the base, a position changing device including a working table is arranged on the stand column, and a coaxially positioning and clamping device, which includes two V-shaped positioning blocks, two V-shaped clamping blocks, four shaping and clamping blocks and a gasket block, is arranged on the working table of the position changing device; and the two V-shaped positioning blocks and the two V-shaped clamping blocks are connected with bolts to position the end shaft of the brake beam, the two V-shaped positioning blocks are fixed at two ends of the working table, the four shaping and clamping blocks are fixed at the parts near to the two ends of the working table, bolts are welded with the gasket block through the shaping and clamping blocks wholly as to fix the brake beam. The fixture for the full welding of the brake beam prevents the deformation after the full welding, improves the welding quality of the brake beam and the production efficiency, and is convenient to operate.

Description

Brake beam full weld jig

Technical field

The utility model relates to a kind of rolling stock maintenance jig, the novel jig of particularly a kind of end axle of brake beam location welding.

Background technology

In the brake beam welding procedure of rolling stock, adopt at present and earlier it is carried out spot welding, and then carry out full weld.Spot welding is for the length overall of determining brake beam and the horizontal five equilibrium of end axle.But when ignoring full weld brake beam is produced the influence of micro-strain, influence welding quality, caused the potential danger of car accident.And production efficiency is low, operation inconvenience.

The utility model content

The technical problem that the utility model solved provides the novel jig of a kind of end axle of brake beam location welding, has effectively prevented the distortion behind the full weld, improves the brake beam welding quality, has improved production efficiency, and is easy to operate.

The technical solution of the utility model: a kind of brake beam full weld jig, it comprises base, column is installed on base, column is provided with displacement device, displacement device comprises work top, the coaxial positioning clamping device is set on the work top of described displacement device, and described coaxial positioning clamping device comprises two V-type locating pieces, two each and every one V-type clamps and four setting grip blocks and cushion blocks; Two V-type locating pieces and two V-type clamps are located end axle of brake beam with bolted on connection, two V-type locating pieces are fixed by bolts on the work top two ends, four setting grip blocks are fixed by bolts to proximal end, two ends on the work top, by setting grip block and cushion block welding one, be used for fixing the brake beam body with bolt.

As a kind of improvement of the present utility model, another coaxial positioning clamping device also is set on the work top of described displacement device, two coaxial positioning clamping devices are symmetrically distributed on the work top.

Described displacement device comprises major axis and minor axis, and described major axis and minor axis are installed in the bearing block, and major axis is connected with flange by key, is fixed on the column with the hole of pin by the flange hole diverse location.

The utility model has effectively prevented the distortion behind the full weld, improves the brake beam welding quality, has improved production efficiency, and is easy to operate.

The specific embodiment

Now by following preferential embodiment the utility model is carried out non-limitative illustration and explanation, these embodiment only provide as an example with reference to accompanying drawing.

See Fig. 1,2,6, concrete structure is as follows: column 2 is installed on base 1, displacement device is installed on column again.The work top 12 of displacement device is by welding with axle 5,15, and axle 5,15 is installed on the column 2,17 by

bearing block

6,16 respectively.See Fig. 7, major axis 5 is connected with flange 3 by key 19.See Fig. 3, at work top 12 upper and lower faces coaxial positioning clamping device 20 and coaxial positioning clamping device 21 are installed, both are symmetrically distributed on the work top 12.4 V-arrangement locating pieces 7 are fixed on work top 12 two ends with bolt 14 respectively, and 8 eight setting grip block 9 (see figure 4)s are fixed on the work top proximal end with bolt 10 respectively.As Fig. 4, cushion block 18 is integrally welded with the bolt 13 that is installed on the setting grip block.Regulate the position of cushion block 18 by adjusting bolt 13, thereby play the position of regulating brake beam body 11.

Simple operation principle: 2 brake beams 11 can be put on the V-arrangement locating piece 7, clamp (see figure 5),, regulate the position of brake beam body, clamp, prevent draw ring behind full weld, produce deformation by regulating the position of bolt 13 by V-type clamp 8.Then, rotary work table top 12 is that the brake beam body is adjusted to suitable welding position, is fixed on column 2 with pin 4 by flange 3, can carry out brake beam and form full weld.

In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of this patent requirement.
