Abstract
The utility model discloses an elasticity pin for in welding frock, this elasticity pin is including pin body (1), axial aperture (2) are established at pin body (1) bottom center, four equipartitions were established to pin body (1) bottom radial slot (3) lead to axial aperture (2), establish 30 cone angle circular conical surface (4) on the bottom face of cylinder of pin body (1), 30 cone angle circular conical surface (4) upper band one number 45 chamfer (5), establish 16 cone angle circular conical surface (6) on the top face of cylinder of pin body (1), 16 cone angle circular conical surface (6) upper band two numbers 45 chamfer (7), be equipped with on the face of cylinder of pin body (1) one V -arrangement groove (8). The utility model provides an among the welding fixture because the work piece is big, the locating hole precision is poor, pin positioning is difficult, during the installation fee, the tight reliability subalternation problem of locating clip, reduced welding support time, improved weld forming's work efficiency, fixture is reliable more stable good, has improved product quality.
Description
Technical field
The utility model relates to tower machine parts, is specifically related to the Elastip pin for welding tooling.
Background technology
Welding tooling also claims weld jig, is the one equipment of determining position relationship while welding for parts. Pin is folderConventional setting element in tool, pin has straight pin, rhombus pin etc., different pins role in work piece positioning is tight is also eachThere is difference. Because the parts volume of the required location of welding tooling is often larger, and the different machining of positioning precisionSuch height that fixture used requires, therefore its setting element has its certain particularity.
Summary of the invention
The purpose of this utility model is: a kind of Elastip pin for welding tooling is provided, realizes positioning function, guaranteeIn welding process, location is reliable and stable, reduces workpiece installation difficulty.
Technical solution of the present utility model is: this Elastip pin comprises pin body, the bottom center of pin bodyIf axial aperture, four uniform radial slots are established in the bottom of pin body, and radial slot connects axial aperture, the bottom of pin bodyOn the face of cylinder, establish 30 ° of cone angle taper seats, on 30 ° of cone angle taper seats, be with 45 ° of chamferings No. one, on the face of cylinder, top of pin body, establish16 ° of cone angle taper seats, are with 45 ° of chamferings No. two on 16 ° of cone angle taper seats, the face of cylinder of pin body is provided with a V-shaped groove.
The utlity model has following obvious advantage: 1, Elastip pin is by 45 ° of chamferings and 16 ° of cone angle taper seats and 30 °Cone angle taper seat, relative with the locating hole of workpiece fast, positioning stablity is reliable; 2, four radial slots and axial aperture make pin toolHave certain elasticity, automatic fine tuning, eliminates the location difficulty that four position of positioning hole errors of upper rotary tower body are brought; 3, V-shaped grooveOutlet passageway when installing with locating hole, guarantees that position fixing process completes smoothly, improves the efficiency that workpiece is installed; 4, structure letterSingle, design science, with low cost, be convenient to promote the use of.

In figure: 1 pin body, 2 axial aperture, 3 radial slots, 430 ° of cone angle taper seats, No. 5 45 ° of chamferings, 616 °Cone angle taper seat, 7 No. two 45 ° of chamferings, 8V shape groove.
Detailed description of the invention
As shown in Fig. 4-5, this Elastip pin comprises pin body 1, and the bottom center of pin body 1 is established axial aperture 2, pinFour uniform radial slots 3 are established in the bottom of nail body 1, and radial slot 3 connects axial aperture 2, on the face of cylinder, bottom of pin body 1If be with 45 ° of chamferings 5 No. one on 4,30 ° of cone angle taper seats 4 of 30 ° of cone angle taper seats, establish 16 ° on the face of cylinder, top of pin body 1On 6,16 ° of cone angle taper seats 6 of cone angle taper seat, be with No. two 45 ° of chamferings 7, the face of cylinder of pin body 1 is provided with a V-shaped groove 8.
As Figure 1-3, in the welding tooling of engaging lug sheet metal forming, welding tooling below and the upper bracket that seam is goodSoldering member monaural plate is connected, and top is connected by the ears plate of seam with upper rotary tower body; The bottom of this Elastip pin is contained inIn four holes of clamp body, insert in four locating holes of upper rotary tower body main body with the top of 30 ° of cone angle taper seats 4, determineUpper rotary tower body main body and clamp body relative position, by 7,16 ° of cone angle taper seats of No. two 45 ° of chamferings 6 fast and the determining of workpieceHole, position is relative, eliminates the site error of upper rotary tower body four locating holes by Elastip pin automatic fine tuning, V-shaped groove 8 as withOutlet passageway when locating hole is installed guarantees that position fixing process completes smoothly.
The utility model efficiently solves in welding tooling fixture because workpiece is large, locating hole low precision, pin location are difficult,When installation fee, location clamps the problem such as poor reliability, reduced welding non-cutting time, improved the operating efficiency of welding fabrication,Fixture locates that reliability and stability is good more, has improved product quality.
