Description
Technical field
The present invention relates to laser welding T connector fields, in particular to the fixture for laser welding T connector.
Background technique
There are the floor and bottom plate of many thinner thicknesses in structure in rail vehicle, is usually in one between floor and bottom plate
Kind T font state needs to weld the two when car body is processed in manufacture, and the fixture for being suitable for T-type welding point at present is also less.
After welding between floor and bottom plate, a kind of T font welding point is just formed.Because this T-type structure component belongs to greatly thin
Wall-like state, so being easy to produce deformation in the welding process.Since laser welding is concentrated with energy, welding deformation is small to wait spies
Point, so it is particularly suitable to use it to T-type Member Welding.Laser welding has higher requirement to weld seam assembly precision, so to sum up
A kind of structure of two point designs is simple, and assembly precision is high, and operation difficulty is small, can quickly be accurately positioned the T-type of suitable laser welding
Joint clamp is necessary.There is presently no a kind of T connector welding fixtures to be able to satisfy above-mentioned requirements.
Summary of the invention
The main purpose of the present invention is to provide the fixtures for laser welding T connector, to solve T-type in the prior art
The problem of connector deforms in the welding process.
To achieve the goals above, the present invention provides a kind of fixtures for laser welding T connector.This is used for laser
The T connector that the fixture of welding T connector is targeted includes orthogonal bottom plate and floor, and the fixture, which is included in, to be welded
Make the bottom plate and the orthogonal positioning mechanism of floor in journey, the positioning mechanism include pedestal, it is vertical with the pedestal simultaneously
Be located at the pedestal axial sides two columns and with the pedestal and the matched pressing device of column；The compression
Device includes two grasping plates being oppositely arranged, the connection connecting between described two grasping plates and with one end of the grasping plate
Plate, positioned at described two grasping plates the other end protrusion or groove and through the connecting plate and with the connecting plate screw thread connect
The hold-down column connect；The pressing device is connect by the protrusion or groove with the column and pedestal, and the pressing device can
Along the axial movement of the pedestal, the pressing device can moving up and down along the column.
The structure of fixture for laser welding T connector of the invention is very simple, fixed and compression floor and bottom plate
It is very easy to use using same pressing device.Pressing device realizes mobile and dismounting using protrusion or groove, is more convenient
Management and use.The present invention is very suitable for the T-type of the floor of thinner thickness and bottom plate in rail vehicle and welds, and can effectively prevent
Weld the generation of deformation.
Further, the pressing device be three, connect respectively with described two columns, and the column on the left of bottom
Seat is connected and is connect with the pedestal on the right side of the column.As a result, when the bottom plate be two when, can be to floor at left and right sides of
Bottom plate is all positioned and is compressed.
Further, the opposite face of described two columns is equipped with axial vertical slot, is equipped between described two columns
The backing plate for matching and being moved up and down along the vertical slot with the vertical slot.As a result, can preferably support rib, prevent floor
The bending deformation under the active force of hold-down column.
Further, the column is axially arranged with scale；The backing plate is axially arranged with scale.It is precisely controlled as a result,
The position of floor.
Further, when the other end of described two grasping plates is provided that protrusion, on the axial sides face of the pedestal
Match equipped with the width with the matched transverse groove of protrusion, the protrusion and the distance between connecting plate and the column.
Structure is simple as a result, production easy to process.
Further, the pedestal is equipped with and the matched concave surface of the base plate thickness.Make matching for bottom plate and pedestal as a result,
It closes more closely, further suppresses welding deformation.
Further, the pedestal is axially arranged with scale；The connecting plate is axially arranged with scale.
Further, the hold-down column is at least two and is evenly distributed along the axial direction of the connecting plate.Make rib as a result,
Being more uniformly stressed for plate and bottom plate, further suppresses welding deformation.
Further, the hold-down column include set the threaded body of rod, set on the post seal face and be set to
Rotation section at the top of the body of rod, the diameter of the seal face are greater than the diameter of the body of rod.Increase the effect of hold-down column as a result,
Face prevents pressing force from concentrating and being deformed.
As it can be seen that structure of the invention it is very simple, it is very easy to use, conveniently manage and maintain.The present invention is very suitable to
The T-type of the floor of thinner thickness and bottom plate welds in rail vehicle, can effectively prevent the generation of welding deformation.
The present invention is described further with reference to the accompanying drawings and detailed description.The additional aspect of the present invention and excellent
Point will be set forth in part in the description, and partially will become apparent from the description below, or practice through the invention
It solves.
