Description

A kind of assembling cushion block used when rivet welding

Technical field

The utility model relates to welding tooling technical field, a kind of used when more particularly to rivet welding assembling cushion block.

Background technique

Be conducive to the characteristic of metal material, the angle of bending part is difficult to unification, and low precision causes part bending part assembling When due to bending angle error problem, assembly clearance cannot be guaranteed after tooling clamping, in two workpiece junction some places Gap is big, and some places gap is small, or even situation very close to each other occurs, affects the welding quality and precision of assembling.

It is excessive that overlap, weld seam welding angle are easy to appear when assembly clearance is excessive, so as to cause the serious problem of welding deformation, and When assembly clearance is too small, weld seam is easy to appear the defects of lack of penetration, root of weld fusion is bad, if can guarantee the big of assembly clearance It is small uniformly and suitable, then it can greatly improve weldquality.

Utility model content

The assembling cushion block that the utility model uses when mainly solving the technical problems that providing a kind of rivet welding carries out two workpiece The gap of junction limits, and promotes working efficiency and welding quality.

In order to solve the above technical problems, the technical solution that the utility model uses is: use when providing a kind of rivet welding Assembling cushion block, comprising: gap is inserted into piece, link block and taps force block, gap insertion piece and taps force block difference For square, the link block setting is inserted into piece in gap and is tapped between force block, and the thickness of the gap insertion piece, which is less than, to be struck The thickness of force block is hit, the bottom of the link block is provided with an inclined-plane, and the inclined-plane extends obliquely and is connected to gap It is inserted into piece bottom surface rear end and taps between force block front end face.

In one preferred embodiment of the utility model, the gap insertion piece, link block and the top surface for tapping force block It is flush.

In one preferred embodiment of the utility model, the gap insertion piece, link block and percussion force block are integrated Change steel construction.

In one preferred embodiment of the utility model, the setting of gap insertion piece the first workpiece and second workpiece it Between carry out gap determination.

In one preferred embodiment of the utility model, gap insertion piece two sides respectively with the first workpiece and second Workpiece is in contact.

In one preferred embodiment of the utility model, the second workpiece is bending part, first workpiece and second It is provided with several gap insertion pieces between workpiece and carries out gap limit.

The beneficial effects of the utility model are: the utility model point out a kind of rivet welding when the assembling cushion block that uses, selection Piece is inserted into thickness and the consistent gap of required assembly clearance, and gap insertion piece is inserted between the first workpiece and second workpiece The restriction for carrying out gap, when tooling clamps, the first workpiece and second workpiece stress and piece guarantee workpiece group is inserted by gap The size in gap is filled, and ensures gap uniformity, after assembling tack welding, it is quick that percussion force block can be beaten by awl Taking-up gap be inserted into piece, operate conveniently, assembly clearance size is uneven when avoiding bending part assembling or gap is too small and leads Lack of penetration situation is caused, is conducive to promote welding quality and assembling product precision.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

The structural schematic diagram for assembling one preferred embodiment of cushion block that Fig. 1 is used when being a kind of rivet welding of the utility model；

The assembling cushion block that Fig. 2 is used when being a kind of rivet welding of the utility model is in the first workpiece and second workpiece peace when assembled Fill schematic diagram；

Fig. 3 is the sectional view along A-A of Fig. 2.

Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Fig. 1 ~ Fig. 3 is please referred to, the utility model embodiment includes:

The assembling cushion block used when a kind of rivet welding, comprising: gap is inserted into piece 11, link block 12 and taps force block 13, institute Stating gap insertion piece 11 and tapping force block 13 is respectively square, the link block 12 setting gap insertion piece 11 and tap by Between power block 13, the gap insertion piece, link block and percussion force block are integrated steel construction, the group used when forming rivet welding Fill cushion block 1.

The determination that gap is carried out between the first workpiece 2 and second workpiece 3, the gap is arranged in the gap insertion piece 11 Insertion 11 two sides of piece are in contact with the first workpiece 2 and second workpiece 3 respectively, and when assembling is constructed, clamping tool is until the first work Part 2 and second workpiece 3 come into full contact with gap insertion 11 two sides of piece respectively, and reselection suitably clicks through after rechecking relative dimensions Row spot welding is fixed.

The thickness of the gap insertion piece 11 is less than the thickness for tapping force block 13, due between the workpiece group clock synchronization root of weld Gap is generally 0-3mm, relatively small, so the thickness of gap insertion piece 11 is relatively small, and the thickness for tapping force block 13 is big, Resistance to beating effect is good.

The bottom of the link block 12 is provided with an inclined-plane 14, and the inclined-plane 14 extends obliquely and is connected to gap and inserts Enter 11 bottom surface rear end of piece and tap between 13 front end face of force block, inclined-plane 14 carries out the evacuation of groove, so that piece 11 is inserted into gap Between 3 junction of the first workpiece 2 and second workpiece, the connection for strengthening gap insertion piece 11 and percussion force block 13 is strong Degree.

The top surface of the gap insertion piece 11, link block 12 and percussion force block 13 is flush, so that built-up time gap is inserted Enter piece 11, link block 12 and the top surface abutting second workpiece 3 for tapping force block 13, the front end face for tapping force block 13 is close to first Workpiece 2 carries out the quick fixation of assembling 1 position of cushion block, reduces shaking problem.

The second workpiece 3 is bending part, and due to bending material and technical problem, the angle of second workpiece 3 is difficult to ensure, When assembling, needs to be provided with multiple gap insertion pieces 11 between the first workpiece 2 and second workpiece 3 and carry out gap limit, then The first workpiece 2 and second workpiece 3 are clamped, progress spot welding is fixed after rechecking relative dimensions, taps force block 13 finally by beaing And take out assembling cushion block 1.Uniform ideal assembly clearance is obtained, guarantees the welding quality of weld seam.

In conclusion the utility model point out a kind of rivet welding when the assembling cushion block that uses, it is easy to operate, be conducive to obtain Uniform ideal assembly clearance, guarantees the welding quality of weld seam.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass, is also included in the patent protection scope of the utility model.
