The projection welding bolt testing tool disclosed by the utility model has a simple structural design, has high repeated utilization rate; and by adopting the standard component, the projection welding bolt testing tool reduces the labor intensity of testing personnel, improves the testing effect and testing quality, and has stronger applicability.
Description
Technical field
The utility model relates to bolt and detects the frock technical field, especially designs a kind of projection welding bolt testing tool.
Background technology
At automobile manufacturing enterprise, many parts need use welding fixing, and wherein the use of sealing-off bolt is comparatively extensive.After protruding bolt welding is finished, need to detect projection welding bolt weld seam twisting resistance intensity, to guarantee the constant intensity of projection welding bolt.
At present, when detecting projection welding bolt weld seam twisting resistance intensity, generally be directly to use nut to be placed on the projection welding bolt to be measured, use the digital display spanner to revolve peaceful nut then and detect.Along with the increase of revolving Ning Li, the pressure of nut is big more, can't directly react projection welding bolt weld seam twisting resistance intensity.In addition, above-mentioned testing process causes the damage that detects with nut easily, has increased the detection cost, and detects very difficulty of nut dismounting, has increased testing staff's labour intensity, has reduced detection efficiency.
Summary of the invention
It is a kind of simple in structure, easy to operate that the utility model provides, and can guarantee the projection welding bolt testing tool of detection efficiency and detection quality simultaneously.
A kind of projection welding bolt testing tool comprises the sleeve of vertical setting and the test section that the sleeve lower end vertically is provided with, and described test section comprises top and the fixing fixing standard component of adapter and top and adapter bottom of sleeve; Center, described sleeve top is provided with locating slot, is used for engaging with the port of digital display torque spanner; Described adapter bottom center is provided with the mounting groove that cooperates with standard component; Described standard component bottom center is provided with screw, is used for and the projection welding bolt.
Sleeve can be selected standard cartridges common on the market for use, and the specification of sleeve can determine according to the size of digital display torque spanner port size and adapter, adjusts according to actual needs and selects, and is easy to assembly.The center of commercially available standard cartridges generally is provided with the similar and different through hole of two ends shape.For making things convenient for the fixing of adapter and sleeve, adapter top end generally is provided with cylindrical, square or rectangular fixing lug boss, and the shape in the bottom center hole of the sleeve of selection and the shape of fixing lug boss will be consistent, so that welding.Can select the fixing or bolt of welding between sleeve and the adapter, generally select for use welding fixing.
Standard component can be selected common square weld nut for use, and strength grade is 8 grades, guarantees the intensity of nut thread when bolt and nut is tightened.The big I of square weld nut is determined according to the size of reality projection welding bolt double-screw bolt to be measured, is generally supporting selection.Generally between standard component and the adapter select welding fixing, also can select other fixed forms to replace welding fixing, for example also can by screw thread fix or key fixing etc.
The digital display torque spanner can be selected digital display torque spanner common on the market for use, and the xsect of the port of digital display torque spanner commonly used is a square, and for ease of detecting, can select an end locating slot for use is that xsect is the sleeve of foursquare rectangular parallelepiped groove.
During the actual use of projection welding bolt testing tool of the present utility model, at first the standard component with testing tool is screwed on the double-screw bolt of the projection welding bolt that welds, the port of digital display torque spanner is inserted in the locating slot of sleeve, with the digital display torque spanner projection welding bolt testing tool is screwed onto prescribed torque then; Do not have obvious distortion, crackle as the projection welding bolt less than loosening and bolt root welded seam area, then this projection welding stud weld engages lattice; As bolt falling, welded seam area obvious crackle or significantly protruding is arranged, then this projection welding bolt welding is defective.
Projection welding bolt testing tool of the present utility model, structural design is simple, the repeat usage height; The employing of standard component has reduced testing staff's labour intensity, the detection efficiency of raising and detection quality, and applicability is stronger.
