Abstract
The utility model relates to a welding fixture for a grid-type bottom frame of a full-load bus. First and second guide rails parallel to each other are arranged on a base; a clamp body is provided with first and second clamping grooves respectively; the sections of the first and second clamping grooves are inversely U-shaped, and the first and second guide rails are respectively clamped in the first and second clamping grooves; a positioning locking mechanism and a compacting mechanism matched with the first and second guide rails are respectively arranged in the first and second clamping grooves; and the positioning locking mechanism and the compacting mechanism are respectively fixed with the clamp body. According to the technical scheme, the first and second guide rails are arranged on the base, the clamp body is provided with the first and second clamping grooves matched with the first and second guide rails, the first and second guide rails are fixed in the first and second clamping grooves through the positioning locking mechanism and the compacting mechanism, and only the positioning locking mechanism and the compacting mechanism are operated when the clamp body is required to be replaced, so the welding fixture is simple, convenient and wide in applicability.
Description
Technical field
The utility model relates to a kind of all-loading coach, relates to specifically a kind of all-loading coach grating type underframe welding tooling.
Background technology
All-loading coach grating type underframe is by cutting section bar and the little assembly of tie-beam that the rectangular tube assembly welding becomes, finish by assembling, welding, correction, the little assembly of a underframe has more than 100, the assembly working amount is large, must in frock, assemble and weld, like this guarantee product quality and production efficiency.At present, frock commonly used is: weld a rectangular tube base, clamp body is welded on the base again, because the passenger vehicle demand is personalized more, such as the selection of front-rear axle, front and rear suspension, the selection of engine, gearbox, the selection of fuel tank position, the selections of steering wheel etc. all can cause the difference of underframe corresponding site, and this frock can only be produced the part of underframe, other parts still need manual the assembling, cause workload to increase, and the uniformity of product can not get ensureing, quality is also unstable.
The utility model content
The purpose of this utility model is to provide a kind of all-loading coach grating type underframe welding tooling, and these welding tooling mounting or dismounting are convenient, and applicability is wide.
For achieving the above object, the utility model has adopted following technical scheme: the clamp body that comprises base and base top, described base be provided be parallel to each other first, the second guide rail, be respectively equipped with first on the described clamp body, the second draw-in groove, described first, the cross section of the second draw-in groove is inverted U-shaped, and first, the second guide rail is fastened on respectively first, in the second draw-in groove, described first, also be respectively equipped with and first in the second draw-in groove, the location locking mechanism that the second guide rail matches and hold-down mechanism, described location locking mechanism and hold-down mechanism fix with clamp body respectively.
The cross section of the first guide rail of the present utility model is that chamfer is trapezoidal, described location locking mechanism comprises the wedge that matches with the first guide rail, and wedge is fixed on the first bolt on the clamp body, the hypotenuse of wedge matches with the hypotenuse of the first guide rail, the cross section of described the second guide rail is inverted L-shaped, and described hold-down mechanism comprises the L shaped briquetting that matches with the second guide rail and L shaped briquetting is fixed on the second bolt on the clamp body.
First, second draw-in groove of the present utility model and clamp body are welded and fixed.
Be respectively equipped with first, second backing plate between first, second guide rail of the present utility model and the base.
First, second guide rail of the present utility model links to each other with first, second backing plate and base by bolt.
As shown from the above technical solution, the utility model is by arranging first, second guide rail at base, first, second draw-in groove match with first, second guide rail is set at clamp body, by location locking mechanism and hold-down mechanism first, second guide rail is fixed in first, second draw-in groove, when needs are changed clamp body, only need location locking mechanism and hold-down mechanism operated and get final product, simple and convenient, applicability is wide.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of all-loading coach grating type underframe welding tooling as shown in Figure 1, the clamp body 2 that comprises base 1 and base 1 top, described base 1 is provided with first, second guide rail 3,4 that is parallel to each other, first, second guide rail 3,4 and base 1 between be respectively equipped with first, second backing plate 11,12, first, second guide rail 3,4 by bolt and first, second backing plate 11,12 and base 1 link to each other.Be welded with respectively first, second draw-in groove 5,6 on the clamp body 2, first, second draw-in groove 5,6 cross section are inverted U-shaped, and first, second guide rail 3,4 is separately positioned in first, second draw-in groove 5,6, also be respectively equipped with location locking mechanism and the hold-down mechanism that matches with first, second guide rail 3,4 in first, second draw-in groove 5,6, described location locking mechanism and hold-down mechanism fix with clamp body 2 respectively.Specifically be exactly, the cross section of the first guide rail 3 is that chamfer is trapezoidal, location locking mechanism comprises the wedge 7 that matches with the first guide rail 3, and wedge 7 is fixed on the first bolt 9 on the clamp body 2, the hypotenuse of wedge 7 matches with the hypotenuse of the first guide rail 3, the cross section of the second guide rail 4 is inverted L-shaped, and hold-down mechanism comprises the L shaped briquetting 8 that matches with the second guide rail 4 and L shaped briquetting 8 is fixed on the second bolt 10 on the clamp body 2.
Briefly, clamp body of the present utility model and first, second draw-in groove are connected as a single entity, base, first, second backing plate and first, second guide rail are connected, when assembling, by location locking mechanism and hold-down mechanism both are assembled into an integral body, when needs are changed clamp body, only need first, second bolt of dismounting can finish the dismounting of clamp body; During installation, need to tighten the installation that first, second bolt can be finished a clamp body for same.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
