Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bolt welding strength detection, in particular to a universal bolt anti-torsion moment detection device. Background Art
[0002] Testing the welding quality of projection welded bolts is a key link in the production process.
[0003] In the prior art, several methods for detecting the torque of projection weld bolts are used. The first method involves welding the projection weld bolts to the sheet metal parts, and then testing the welding strength of the bolts in a destructive manner by tapping them with a hammer or other tool. However, this method has limitations, because sheet metal parts of different materials and thicknesses will lead to differences in welding torque, and can only be qualitatively detected, but cannot provide quantitative test data as a reference.
[0004] The second method is to use a special sleeve with a nut and a digital torque wrench to achieve destructive and non-destructive quantitative detection: in order to measure the bolt torque, the corresponding specification nut needs to be arc welded to the bolt first, and then the corresponding specification sleeve is put on the nut, and finally the torque wrench is turned to measure the torque. Although this method can achieve detection, there are some problems. First, different specifications of nuts and sleeves are required for different bolts, which increases the detection cost. The use of detection nuts requires frequent replacement, which also increases the detection cost; secondly, the contact surface between the nut and the bolt is too small, resulting in instability, affecting the torque transmission, and causing the accuracy of the measured value to decrease; finally, the process of disassembling the detection nut is time-consuming and laborious, affecting the efficiency of the operation process.
[0005] The third method is to achieve quantitative torque detection by using special sockets and torque wrenches: in order to measure the bolt torque, you need to prepare a socket of corresponding specifications with an opening at the top of the socket, and saw the bolt head to prevent the screw from breaking and being unable to be removed. Then screw the socket onto the bolt and apply torque to measure the torque. Although this method is suitable for large-scale and rapid detection, there are still some problems. First, different specifications of sockets are required for different bolts, and each specification of socket is dedicated, which increases the detection cost; secondly, in order to prevent the bolt from breaking and being unable to be removed in the socket when detecting the bolt torque, one end of the screw needs to be sawed before the test, which makes the test process time-consuming and laborious, affecting the efficiency of the operation process.

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0031] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0032] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0034] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.
[0035] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0036] Example
[0037] like Figures 1 to 5 The universal bolt anti-torsion torque detection device shown includes a sleeve 1, a rectangular connecting groove 11 is opened at one end of the sleeve 1, and a hexagonal sleeve groove 12 is opened at the other end of the sleeve 1. A detachable hexagonal bushing assembly 2 is installed in the sleeve groove 12, and an internal thread matching the external thread of the bolt to be detected is provided on the inner wall of the bushing assembly 2.
[0038] The bushing assembly 2 is composed of a first bushing 21 and a second bushing 22. The first bushing 21 and the second bushing 22 are both U-shaped structures. The top surfaces of the two vertical arms of the first bushing 21 are both provided with protrusions 211, and the top surfaces of the two vertical arms of the second bushing 22 are both provided with grooves 221 that cooperate with the protrusions 211. When the first bushing 21 and the second bushing 22 are spliced, a pin 23 is provided through the protrusion 211 of the first bushing 21 and the vertical arm of the second bushing 22 to fix the protrusion 211 and the groove 221.
[0039] The following describes the process flow of the utility model when it works:
[0040] like Figure 6 As shown, the projection welding bolt to be tested is welded to the welded part, and the bushing assembly 2 with the corresponding specifications of the bolt to be tested is placed into the sleeve 1 through the sleeve groove 12. The sleeve 1 with the installed bushing assembly 2 is screwed into the bolt to be tested, and the torque wrench connector is placed into the connecting groove 11 to set the torque standard value.
[0041] Then apply torque to the torque wrench and observe the torque wrench. When the torque exceeds the set standard value, it proves that the projection weld bolt to be tested meets the production requirements. If the projection weld bolt rotates before the torque exceeds the set standard value, it proves that the torque of the projection weld bolt does not meet the production requirements.
[0042] The bolt to be inspected is taken out from the sleeve 1 together with the bushing assembly 2, and then the latch 23 is taken out and the bushing assembly 2 is separated into the first bushing 21 and the second bushing 22, and the inspected bolt can be taken out.
