Abstract

The utility model discloses a sleeve for detecting the strength of a projection welding nut, solving the problems of inaccurate detection results, poor stability and poor generality of the conventional projection welding nut strength detection sleeve. The sleeve comprises a mounting head, an adapter and a connection block. The adapter is fixed on the mounting head and is provided with a connection hole matching with a torque wrench. The mounting head is provided with a mounting hole, and the connection block is arranged in the mounting hole, matching with the mounting hole. The connection block is provided with a clamping hole matching with the projection welding nut. A locking mechanism for locking the connection block is arranged on a side face of the mounting head. The sleeve provided by the utility model has good stability and generality, improves the accuracy of the strength detection of the projection welding nut, and is simple in structure and convenient to use.

Description

A kind of project-welding nut ruggedness test sleeve
Technical field
The utility model relates to a kind of project-welding nut intensity detection instrument, especially relates to a kind of sleeve for detection of project-welding nut intensity.
Background technology
At present, in the automobile welding technology, often nut need be welded on the vehicle body steel plate with projection welder, be used for assembling, the fixing part on the vehicle body.In welding process, intensity to the nut welding has technological requirement, therefore, need carry out ruggedness test to the part after the welding, nut after we use dial torque wrench to welding is usually beaten moment of torsion and is tested, but because the project-welding nut profile is different from plain nut, general Hexagonal jacket can't entangle project-welding nut restriction and rotate, and therefore need limit the rotation of project-welding nut with homemade sleeve.
Granted publication CN201331405Y, the Chinese patent in October 21 2009 Granted publication day discloses a kind of project-welding nut moment of torsion and has detected socket wrench specially adapted for it, one end of sleeve is the sleeve hole that cooperates with project-welding nut to be measured, the other end of sleeve is the outer body in many ways that cooperates with dial torque wrench, and the core of sleeve is provided with the step through-hole that can put into the bolt that cooperates with project-welding nut to be measured.This sleeve needs by bolt project-welding nut to be measured and muff coupling to be integral earlier in use, the moment of torsion of project-welding nut is to pass to dial torque wrench indirectly by bolt, this just can cause the inaccurate of testing result, this sleeve has shallow slot in the lower end of square hole simultaneously, easily cause the deformation of sleeve, poor stability, in addition, the versatility of this sleeve is poor.
The utility model content
The utility model is can cause the inaccurate of testing result for the project-welding nut intensity detection sleeve that solves prior art, the problem of stability and versatility difference, provide a kind of simple in structure, easy to use, stability is good with versatility, and testing result is accurately for detection of the sleeve of project-welding nut intensity.
To achieve these goals, the utility model is by the following technical solutions:
A kind of project-welding nut ruggedness test sleeve, comprise head, adapter and contiguous block are installed, described adapter is fixed on to be installed on the head, described adapter is provided with the connecting hole that matches with dial torque wrench, described installation head is provided with mounting hole, described contiguous block is positioned at mounting hole and mounting hole is suitable, and contiguous block is provided with the hole clipping that matches with project-welding nut, and a described installation side is provided with the latch mechanism for the locking contiguous block.Adapter is used for and the dial torque wrench socket; Contiguous block is provided with the hole clipping that matches with project-welding nut, and contiguous block is positioned at mounting hole and mounting hole is suitable, and fixedly connected by being positioned at holding screw that a side is installed and installation, be convenient to change the contiguous block with hole clipping like this, can improve versatility of the present utility model, put into mounting hole as long as will have the contiguous block of the hole clipping of required form during use, by latch mechanism that contiguous block is fixing with the installation head, then contiguous block is snapped in project-welding nut, at last dial torque wrench is packed in the connecting hole of adapter, the driving torque spanner, if dial torque wrench reaches regulation numerical value, then the project-welding nut welding quality is qualified, and namely intensity is qualified, otherwise, then be defective.
As preferably, described mounting hole is square opening.Square opening is difficult for skidding, and easy to process.
As preferably, the degree of depth of described hole clipping is greater than the thickness of project-welding nut.The assurance project-welding nut can be put into hole clipping fully, guarantees the stressing conditions of project-welding nut, improves the accuracy of testing result.
As preferably, the inwall of described hole clipping is provided with the convex tendon that contacts with the project-welding nut outside wall surface.Convex tendon contacts with the project-welding nut outside wall surface, make the gap between hole clipping and the convex tendon just hold weld seam like this, simultaneously convex tendon also can stressed transmission moment of torsion, avoid owing to have only the stressed solder joint that causes of weld seam to damage, and make project-welding nut stressed more even, can not shake can be with the moment of torsion of the solder joint complete moment of torsion handle that passes to, improve the accuracy that detects, can improve the stability of use again.
As preferably, described convex tendon has four, is separately positioned on the axial centre position of hole clipping inwall.
As preferably, described latch mechanism is holding screw, and described holding screw is positioned to be installed a side and pass a sidewall and contiguous block butt are installed.Clamping screw easy accessibility and simple in structure.
As preferably, described installation head removably connects with adapter.Be convenient to dismounting and to change head or adapter be installed, with contiguous block or the dial torque wrench that is applicable to the different size shape, improve versatility.
As preferably, described installation head is threaded with adapter.
Therefore, the utlity model has following beneficial effect:
(1) stability is good with versatility;
(2) accuracy of raising project-welding nut intensity detection;
(3) simple in structure, easy to use.
