Description
Technical field
The present invention relates to a kind of instruments of inspection, be specifically related to a kind of T sprig welding strength inspection tool.
Background technology
In the field of machining; Usually need test to the welding quality of the T sprig that is welded on plate surface; Existing check system is to utilize instrument such as flat chisel etc. to knock the ad-hoc location of T sprig from specific direction, if when plate just is out of shape, the T sprig does not come off yet; Judge that then welding quality is qualified, on the contrary then defective.This mode is difficult to accurately control size, direction and the application point of percussion power in checkout procedure, thereby can't guarantee that assay is accurate; In addition; Because the size of the application of force, direction, application point all are difficult to control in the process of knocking; If the application of force is excessive or the direction of the application of force, application point are inaccurate, will also possibly make the surface around plate and the T sprig weld produce buckling deformation, thereby influence welding quality.
Summary of the invention
The purpose of this invention is to provide a kind of T sprig welding strength inspection tool, when using inspection of tools T sprig weld strength of the present invention, assay is accurate, and can avoid making plate to produce buckling deformation, and then has guaranteed welding quality.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: a kind of T sprig welding strength inspection tool; This instruments of inspection comprises that a bottom has the sliding part of claw; Sliding part is positioned at the cavity of support member and can moves along the spacing direction of support member; The claw of sliding part at one end towards the bottom accent of the cavity of support member and can catch the termination of T sprig, the other end of sliding part is provided with and is used to drive the travel mechanism that sliding part moves, the support member bottom be provided with supply the T sprig through and place the opening in it.
Can know by technique scheme, when using T sprig welding strength inspection tool of the present invention, the T sprig got in the support member through the opening of support member bottom; By claw the termination of T sprig is caught, moved through the spacing direction of travel mechanism's drive sliding part along support member, at this moment travel mechanism moves sliding part through the spacing direction at support member; Then to the T sprig application of force, in this process, the big I of power is preestablished by travel mechanism; The application point of power is the contact position of the termination of claw and T sprig; The direction of power all the time along the spacing direction of cavity and towards the top of support member cavity accent, that is to say in whole checkout procedure the accurately size of control, direction and application point, just guaranteed that also assay is accurate; Simultaneously also avoid making plate to produce buckling deformation, guaranteed welding quality.
