Abstract
The utility model provides a stud welding quality inspection tool uses this instrument inspection stud welding quality, can not receive the restriction in narrow and small space, overcomes the defect that detection method can damage the double-screw bolt screw thread and damage the panel beating in the past, detection tool includes: one end of the stud sleeve is provided with a detection hole with a reserved depth for being sleeved into the stud to be detected, and the other end of the stud sleeve is used for manual operation; the support body is positioned on the side face of the stud sleeve and connected with the stud sleeve through a length-adjustable device, or the support body is replaced with different lengths, so that the length of the support body is easy to adjust. Therefore, the special tool for inspecting the welding quality of the stud can detect stud welding points with different process requirements.
Description
Technical Field
The utility model relates to a welding detects technical field, especially indicates a double-screw bolt welding quality inspection tool.
Background
In daily life, different parts are connected by studs and nuts, for example, the connection between interior trim parts, wiring harnesses, heat insulation plates and other accessories on automobiles and automobile body metal plates. However, the stud is connected to the metal plate through welding and has a falling phenomenon, and the current stud welding quality inspection method is that 1, a nut is screwed on a screw to check whether the stud can bear the corresponding screwing torque; 2. knocking the stud by using a hammer and the like to check whether the welding is firm; in the method 1, the nut needs to be screwed up manually, so that the detection work cannot be finished at a position with a small space, and in addition, the nut needs to be screwed up by adopting a large external force during detection, so that threads can be damaged, and the root metal plate can be deformed; the method 2 also has the defects of space limitation, screw damage and metal plate deformation at the welding position during detection.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a stud welding quality inspection tool, it has the limited, damage welding stud external screw thread of operating space or causes the welding department panel beating to warp the scheduling problem to solve among the prior art inspection stud welding quality.
In order to solve the technical problem, an embodiment of the utility model provides a stud welding quality inspection tool, include: one end of the stud sleeve is used for manual operation, and the other end of the stud sleeve is provided with a check hole with a reserved depth; the support body is connected to the side face of the stud sleeve, the length of the support body meets the requirements of design and process specifications, namely the length b = a tan x of the support body required by the inspection process specifications (wherein a represents the length of a stud at a welding position, and x represents the angle deviating from the original central line when the stud is bent).
Furthermore, the support body is fixedly connected with the stud sleeve through threads.
Furthermore, the stud sleeve or the support body can be made into a cylinder, a cuboid, an ellipsoid and the like respectively or simultaneously.
Further, the support body can be changed into different lengths according to needs.
Furthermore, the diameter of the stud sleeve is larger than that of the inspection hole and larger than that of the stud to be detected.
Furthermore, the diameter of the screw sleeve is larger than that of the support body position cylinder.
Further, the preset depth of the screw sleeve inspection hole is larger than the length of the detected stud.
The utility model discloses through the design supporter, whether convenient and fast judgement stud welding exists the unqualified quality defect of desoldering, and does not damage double-screw bolt screw thread, welding department panel beating.
Furthermore, because support piece is removable, adjustable length, the stud welding strength that can detect various regions in stud welding quality inspection instrument fast can be used to the stud and resume the original position simultaneously.

Detailed Description
The invention is further explained below with reference to fig. 1 and 2:
the utility model discloses a special tool for stud welding quality inspection, which comprises a screw sleeve 1, wherein one end of the screw sleeve is provided with an inspection hole 3 with a reserved depth, a screw of a welding part to be inspected can be sleeved in the inspection hole, and the other end of the screw sleeve can be used for applying pressure; and the support 2 is used for positioning and checking the bending amplitude of the stud during welding, namely the tangent value of the angle of the stud from the center line when the stud at the welding position is pressed is tanx = b/a (wherein a represents the length of the stud at the welding position, b represents the length of the support, and x represents the angle of the stud from the original center line when the stud is bent). The support piece 2 is connected to one side of the stud sleeve 1 and can be installed on one side of the stud sleeve in a threaded matching mode. For a certain common specification, the supporting piece can also be connected with the screw sleeve in a fixing mode such as welding.
The specific operation and implementation are as follows: inserting a stud sleeve with one end provided with an inspection hole 3 into the detected welded stud, manually applying pressure to bend the stud until the support body 2 is contacted with the sheet metal part, stopping applying pressure, taking out the tool, observing that no macroscopic cracks exist on a welding seam between the stud and the base metal and a heat affected zone, judging that the stud welding quality is qualified, recovering the qualified stud by using the tool, and otherwise, judging that the stud is unqualified.
The length of the support 2 needs to be adjusted for different process inspection specification requirements. The invention can achieve the purpose of adjusting the length by replacing the supporting piece 2 with different lengths, and can also adjust the length of the supporting piece 2 by connecting threads of the supporting piece 2 and the screw column.
While the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
