Abstract
The utility model discloses a welding strength detection device. The device comprises two cylinder-structure detection rods, namely a bolt detection rod and a nut detection rod; a threaded hole is formed at one end of the bolt detection rod, and a counter bore is formed at the other end of the bolt detection rod; and a convex threaded column is arranged at one end of the nut detection rod, and a counter bore is formed at the other end of the nut detection rod. The device has the advantages that the device can detect the welding quality of projection-welding nuts, bolts and studs rapidly, conveniently and effectively, requires low device cost, has a simple structure, and is easy to produce and manufacture.
Description
Technical field
The utility model relates to welding strength inspection tool, especially relates to the instruments of inspection of project-welding nut, bolt and arc stud welding weld strength.
Background technology
In the body of a motor car manufacture process, because the needs of car load part assembling, the welding of project-welding nut, bolt and double-screw bolt is adopted at a lot of positions at present, and these welding cause the instrument of check weld strength also different because welding technology is different with kind.When carrying out ruggedness test, need to prepare the instrument of multiple nut bolt as check, it is low to carry easy confusion and serviceable life, causes cost waste, and efficiency is low simultaneously.The comparatively advanced device in this field is tested for using special dial torque wrench at present.But this kind instrument is because the costliness of price is not suitable for multistation employee's check.
The utility model content
The technical problems to be solved in the utility model be realize a kind of simple in structure, be easy to processing realize, with low cost, portably use weld strength pick-up unit easily.
To achieve these goals, the technical solution adopted in the utility model is: a kind of weld strength pick-up unit, this device is made of two cylindrical structure test bars, be respectively bolt test bar and nut test bar, described bolt test bar one end is a threaded hole, the other end is a counterbore, and described nut test bar one end is the convex thread post, and the other end is a counterbore.
The threaded hole on the described bolt test bar and the screw thread of the convex thread post on the nut test bar cooperatively interact.
The aperture of the counterbore on described bolt test bar and the nut test bar is slightly larger than tested projection welding double-screw bolt external diameter.
The bolt test bar of stating and the degree of depth of the counterbore on the nut test bar are slightly larger than tested projection welding double-screw bolt length.
Advantage of the present utility model is: can quick and easy, effectively detect project-welding nut, bolt and stud welding quality, and installation cost cheap, simple in structure, be easy to processing and manufacturing.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model instructions and the mark among the figure are made brief description:
Fig. 1 is the utility model weld strength pick-up unit structural representation;
Fig. 2 is device bolt test bar shown in Figure 1 and nut test bar combinatorial construction synoptic diagram;
Mark among the above-mentioned figure is: 1, bolt test bar; 2, nut test bar.
Embodiment
According to the described weld strength pick-up unit of Fig. 1, Fig. 2 structural representation as can be known, this pick-up unit is made of two cylindrical structure test bars, be respectively bolt test bar 1 and nut test bar 2, described bolt test bar 1 one ends are threaded hole, the other end is a counterbore, described nut test bar 2 one ends are the convex thread post, and the other end is a counterbore.The screw thread of the convex thread post on threaded hole on the bolt test bar 1 and the nut test bar 2 cooperatively interacts, two test bars can be linked into an integrated entity, the aperture and the degree of depth of the counterbore on bolt test bar 1 and the nut test bar 2 are slightly larger than tested projection welding double-screw bolt external diameter and length.This instruments of inspection material is a mild carbon steel, and through surface hardening thermal treatment, hardness has reached request for utilization, and actual parameter reaches 25N/m for using moment of torsion.
This weld strength testing tool mainly is to detect at project-welding nut, bolt and arc stud welding weld strength, and concrete using method is as follows:
1, for the check of project-welding nut: convex thread post one end that uses nut test bar 2, in the project-welding nut on its screw-in projection welding plate material, vertically knock the test weld strength of project-welding nut of nut test bar 2 with iron hammer, the characteristics of utilizing this instrument to be convenient to operate, effectively avoided the check of former project-welding nut directly in the side with chisel half damage type check by force, cause the mass defect of distortion to workpiece.
2, for the check of projection welding double-screw bolt: the counterbore end that uses bolt test bar 1 or nut test bar 2, because the counterbore degree of depth of the instruments of inspection is slightly larger than the degree of depth of double-screw bolt, and counter bore hole diameters is slightly larger than the Major Diam of double-screw bolt, making the gap of assembling check is transition fit, during check bolt test bar 1 is combined with nut test bar 2, again double-screw bolt is inserted counterbore, rock back and forth with hand and check weld strength whether qualified.
3, for the check of projection welding bolt: the threaded hole one end weldering bolt instruments of inspection that uses bolt test bar 1, the projection welding bolt is screwed in the threaded hole of bolt test bar 1, vertically knock the test weld strength of projection welding bolt of bolt test bar 1 with iron hammer, the characteristics of utilizing this instrument to be convenient to operate, effectively avoided the check of former projection welding double-screw bolt directly in the side with chisel half damage type check by force, cause the mass defect of distortion to workpiece.
