Abstract
The utility model discloses a tool used for measuring the torque of a projection welded bolt or stud, and the tool comprises a torque wrench and a switch sleeve. The switch sleeve is provided with a joining part and a connection part; an axial joining hole is formed on the end surface of the joining part; an axial connection hole is formed on the end surface of the connection part; the torque wrench is connected selectively onto the joining part of the switch sleeve through the joining hole; and the connection hole is provided with screw threads. The actual condition of the projection welded bolt or stud to be measured can be accurately simulated by connecting the joining hole at the upper end of the switch sleeve with the wrench head of the torque wrench and connecting the connection hole at the lower end of the switch sleeve with the projection welded bolt or stud. Therefore, the torsional strength of the projection welded bolt or stud can be safely and accurately measured.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly relates to the torque measurement instrument that is used for a kind of projection welding bolt of body of a motor car double-screw bolt.
Background technology
A large amount of projection welding bolt, double-screw bolt are arranged on the automobile body-in-white, and whether its torque meets the requirements extremely important to postorder assembling influence, and moment of torsion how effectively to measure projection welding bolt, double-screw bolt becomes a problem that is worth discussion.
" (Chen Zhunian writes welding engineer's handbook, China Machine Press, 2002.1) a kind of double-screw bolt, bolt welding strength detecting method are disclosed on the 465th page, promptly adopt and knock or pull curved method, referring to Fig. 4, by a sleeve A projection welding bolt B 1 is pulled and to curve B2, tilt to an angle [alpha], weld strength meets the requirements if weld seam does not destroy.But because the welding quality characteristic of projection welding bolt, double-screw bolt is a twisting strength, what curved inspection was knocked, pulled in employing is the tensile strength of projection welding bolt, adopts this method can not accurately measure the twisting strength of projection welding bolt, double-screw bolt.
The angle of knocking destruction in addition need obtain through a large amount of experiments, and part is destroyed, and cost is bigger, also is not easy control in the real operation.
If test on welding finished product spare, double-screw bolt must carry out repair welding after destroying, and influences outward appearance, has also reduced work efficiency.
The utility model content
The purpose of this utility model is to provide the torque measurement instrument of a kind of features simple structure, easy to use, the projection welding bolt double-screw bolt that can effectively improve the torque measurement accuracy, has solved technical matterss such as existing torque measurement is inaccurate, inefficiency.
Technical solutions of the utility model are: a kind of torque measurement instrument of projection welding bolt double-screw bolt, comprise torque spanner and a switching sleeve, and described switching sleeve is provided with a convergence part and a connecting portion; On the end face of described convergence part, be provided with an axial convergence hole; On described connecting portion end face, be provided with an axial connecting hole; Described torque spanner selectively is connected on the convergence part of described switching sleeve by described convergence hole; Described connecting hole is provided with screw thread.By a switching sleeve, the convergence hole of its upper end is connected with the spanner of described torque spanner, the connecting hole of its lower end is connected with tested projection welding bolt or double-screw bolt, can accurately simulate the actual condition of projection welding bolt or double-screw bolt, under non-destructive situation, can obtain projection welding bolt double-screw bolt twisting strength accurately.
As a kind of preferred version of the present utility model, described convergence hole has a polygonal xsect, and is consistent with spanner on the described torque spanner.
As a kind of further preferred version of the present utility model, on the convergence part of described switching sleeve, also be provided with a pilot hole that radially runs through, described pilot hole is near the end face of described convergence part.Described convergence hole is provided with the bottom, the locking ball position consistency of described pilot hole on the distance of this bottom and the described torque spanner spanner.Position handled easily personnel's proper operation by the locking ball on the spanner of this pilot hole and described torque spanner.
As a kind of further preferred version of the present utility model, the xsect of described convergence hole is a square.The spanner of this foursquare convergence hole and conventional torque spanner is adaptive, can better use conventional torque spanner.The shape of this convergence hole also can be other and the adaptive shape of described torque spanner spanner.
The degree of depth of described connecting hole is less than the length of tested projection welding bolt, make the end of described tested projection welding bolt prop up the described bottom of connecting hole that is, at this moment, be rotated further described switching sleeve, described tested projection welding bolt or double-screw bolt are produced a power of reversing, this tested projection welding bolt is carried out the test of twisting strength by the torque spanner that connects on the described switching sleeve convergence hole.
