Patent document 201410807276.0 discloses a kind of racing car welding clamp of vehicle frame, including platform, platform are equipped with Inverted T shaped groove, is equipped with 4040 aluminium section bar of level, 4040 aluminium section bar both ends of level are respectively by T-shaped solid on the inverted T shaped groove face of platform Clamp plate is fixedly connected with platform；It is opposite on 4040 aluminium section bar of level to be equipped with L-type gusset joint plate, two with respect to L-type gusset joint plates it Between be connected with vertical 4040 aluminium section bar；Be equipped with arc groove strap on vertical 4040 aluminium section bar, arc groove strap by Arc groove fixed plate and U-bolt composition, when use, are fastened vehicle frame steel pipe clamp with arc groove strap.

Patent document 201220113121.3 discloses a kind of auxiliary frame welding fixture, including positioner, pressing device；Also Including turnover device, mobile running gear；Mobile running gear can horizontal level movement, mobile running gear includes removable bottom Seat, column, column are installed on movable pedestal；There is bearing hole on column；Include swing bolster and main branch on turnover device Support, rotation axis, rotating disk, clump weight；Rotation axis is slidably matched with the swivel bearing on column；Rotating disk and swing bolster and master Support is fastenedly connected by rotation axis；Clump weight is installed on the rotating pan；It is horizontal that positioner, pressing device are fixed on rotation On beam and main support；Rotating disk, which rotates, drives rotation axis, swing bolster and main support both circumferentially to rotate upset work with clump weight Part indexing, clump weight, to equilbrium position, implement welding with swing bolster and main support and workpiece turning.

Body of a motor car is generally made of outer covering piece, internal covering part and skeleton, and the steel plate thickness of covering is generally 0.8-1.2mm, the steel plate thickness of skeleton is mostly 1.2-2.5mm, that is to say, that they are mostly sheet member.Welding fixture is set For meter, the objective of design of welding jig is to limit the free degree of 6 direction movements.There are following for existing welding fixture anchor point Deficiency, on the one hand, cause vehicle frame to be deformed since workpiece is acted on by clamping force at anchor point；On the other hand, the number of positioning surface Measure and than more conservative, it is peaceful how not few, cause easy generation interference, pitch of holes deviation between anchor point and anchor point to be up to L ±0.03。

Utility model content

The utility model aim, which is intended to provide between a kind of reduction anchor point and anchor point, produces interference, avoids positioning Cause the Frame Welding fixture of the deformation of vehicle frame at point because of stress effect.

To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：

Frame Welding fixture, including angle bearing, different in nature connecting plate, hydraulic cylinder, lower positioning collet, upper positioning collet, Crossbeam is compressed, the opposite sex connecting plate lower left is equipped with the first screw hole for joint angle bearing, the opposite sex connecting plate bottom right Side is equipped with the first through hole for being used for connecting hydraulic cylinder, and the opposite sex connecting plate upper left side, which is equipped with, to be used to place lower positioning collet First notch；

The hydraulic cylinder includes cylinder Part I and cylinder Part II, and the cylinder Part I is built-in with energy Lower movable cylinder Part II, the cylinder Part II top pass through movable part and connect compression crossbeam.

Using the utility model of above-mentioned technical proposal, different in nature connecting plate is added, folder is reasonably arranged by different in nature connecting plate The unitary construction of tool, it is ensured that lower positioning collet and each division of upper positioning collet apart from gap, avoid repeatedly dividing at anchor point Close, the different clamping forces effect that workpiece is subject to after division repeatedly, and cause the deformation of vehicle frame；Reduced and positioned by adjustment angle bearing Interference is produced between point and anchor point, control hole spacing deviation is less than L ± 0.02.

When specifically used, cylinder Part II moves upwards, closes lower positioning collet and upper positioning collet, similarly, Cylinder Part II moves downward, positioning collet and upper positioning collet under opening, and after opening, changes the tack weld of vehicle frame.

Further limit, the angle bearing includes bearing Part I, bearing Part II, and bearing Part III is described Bearing Part I and bearing Part II form L-shaped, and the bearing Part III is right angled triangle, the bearing the 3rd Divide long side connects bearing Part I, its short side connects bearing Part II.

Pass through bearing Part I, bearing Part II, the angle bearing that bearing Part III is formed, Quick-positioning clamp.

Further limit, the movable part includes I-shaped type bearing support, and movable rotation-shaft, the compression crossbeam rear end, which is equipped with, to be used In the first circular hole of insertion movable rotation-shaft.

Further limit, the opposite sex connecting plate upper right side is equipped with gib block.

Further limit, the cylinder Part I upper end is equipped with outlet pipe, and the cylinder Part I lower end is equipped with Admission line.

Further limit, the compression crossbeam inner wall is equipped with the first pad.

The first pad is added, the abrasion of lower positioning collet and upper positioning collet is reduced, improves repeat usage；Meanwhile keep away Exempt from the deformation for causing vehicle frame at anchor point because of stress effect.

Compared with prior art, each component of the fixture is cheap for the utility model, and convenient dismounting, can reuse, make With long lifespan, cost is greatly reduced.
