Description
Technical field
The present invention relates to a kind of welding tooling of workpiece, specifically a kind of loading space crossbeam anti-deformation welder.
Background technique
Middle-size and small-size truck cargo compartment crossbeam is the weighing and support member of loading space bottom, the crossbeam by cornual plate, U-shaped etc. even
It connects positioning element to connect with other crossbeams, and supports the carriage body structure on loading space top jointly.
Currently, the welding of the components such as the welding piece on crossbeam top is mainly completed by human weld, due to the ruler of crossbeam
It is very little longer, and the quantity of intermediate connector is more, under the conditions of crossbeam does not apply prestressed, the crossbeam after the completion of welding is even
Fitting stress can generate bending deformation under shrinking.Although above-mentioned deformation is less, the company of crossbeam and upper box body will affect
Precision is connect, concentrated stress, the final service life for influencing loading space are generated.
For this purpose, the defect based on existing welding technique, applicant proposed a kind of technical solution, which can be to not
Crossbeam with length generates opposite stress deformation before welding, to compensate the deflection after welding, and after the completion of ensureing welding
Crossbeam bend amount in allowed limits.The erecting and welding precision that ensure that loading space, improves the service life of product.
Summary of the invention
The purpose of the present invention is to provide a kind of loading space crossbeam anti-deformation welder, which can be to the crossbeam of welding
Pressure in advance, the stress deformation of compensation welding rear cross beam.
To achieve the above object, technical scheme is as follows:
The device includes frame body, and the right end on the frame body top is equipped with the positioning device that workpiece end is fixed, and the left end of frame body is set
There are moveable workpiece end hold-down devices, it is removable equipped with being connect with frame body upper end between the positioning device and hold-down devices
Movable support device.According to the length of crossbeam, support device is moved to the intermediate section of crossbeam, then passes through one end of crossbeam
Positioning device is fixed, at this point, the other end of crossbeam is upturned under the action of support device.Hold-down devices are moved to crossbeam
It tilts end then to push, be depressed into bending compensation range.Crossbeam is under the cooperation of above-mentioned apparatus in the arc to arch upward upwards at this time
Shape.It then can be by the upper end for being welded on crossbeam of all parts for needing to weld respectively.Each component is due to answering when the welding is completed
Power is shunk, and is had the reclinate stress trend of crossbeam, therefore, the amount of bow of preparatory application just can compensate for beam welding and cause
Stress deformation.
Further, the hold-down devices include moving trolley, which is connected with expansion bracket by fixed frame, should
The upper end of expansion bracket is equipped with down transverse beam.It can also be such as arranged directly on fixed frame by the hold-down devices of other structures downward
Flexible air cylinder structure completes pressing action.
Preferably, the expansion bracket includes the U-shaped frame connecting with fixed frame, which is socketed with rectangle rack, the square
The lower end of shape frame is connect with the lower end of U-shaped frame by lower air cylinder.Hold-down devices are located at the lower part of frame body by above-mentioned structure, only
The upper end of rectangle rack is located to the upper end of frame body, saves the space on top.
When crossbeam pushes, the upper surface of crossbeam is contacted at certain gradient in order to which crossbeam is consistently formed with down transverse beam
Face, further preferred, the upper end of the U-shaped frame and the two sides of fixed frame are rotatably connected.
Further, the moving trolley includes car body, the decelerating motor for being fixedly connected on car body upper end, the front and back of car body
Both ends top is connected with by bearing block and walks wheel, the lower part of rear and front end is connected with down wheel by bearing block, in car body
Left and right sidewall is connected with guide roller by mounting base.The upper end of frame body is equipped with station, and the downside of the station is fixed to be connected
Be connected to track girder, it is described on walk wheel, under walk the lower end that wheel is respectively fitting into the upper end and track girder of track girder, guide roller is matched
Close the inner sidewall in track girder.Decelerating motor connection has driving gear, which matches with the rack gear of track girder lower end.
Above-mentioned structure ensure that the steady of trolley travelling, and can share depressing force on track girder, improve moving trolley
Service life.
Further, the positioning device includes locating rack, and the upper end of the locating rack is equipped with positioning cylinder, the positioning gas
The lower end of cylinder is equipped with L-type positioning plate.Place loading space crossbeam when, by one end of loading space crossbeam be placed on L-type positioning plate lower end and and its
It coincide, then L-type positioning plate declines under the action of positioning cylinder, and positions through loading space crossbeam.
In order to avoid L-type positioning plate contacts firmly with crossbeam, further, the telescopic end of the positioning cylinder is by compressing bullet
Spring is connected with telescopic shaft.The lower end of the telescopic shaft is rotatably connected with L-type positioning plate, guarantee crossbeam bending engineering in always with
L-type positioning plate coincide.
Further, the support device includes movable plate, and the upper end of the movable plate is connected with support plate by guide post,
The stackable adjustable plate of multilayer is equipped between support plate and movable plate.
In order to avoid beam surface is not scratched, increase the stress that supporting point shares pushing, further, the support plate
Both ends supporting block is connected with by torsionspring and shaft, the both ends of supporting block are equipped with support roller, set on the inside of supporting block
There is the limited block for being fixed on support plate upper end.
Due to the adoption of the above technical scheme, the invention has the benefit that the bending of application that can be preparatory to loading space crossbeam
Amount, and can compensate for stress deformation caused by beam welding.
