Description

Technical Field

[0001] This utility model relates to the technical field of automobile design and manufacturing, and more specifically, to a welding torque detection sleeve for a grounding bolt and nut assembly. Background Technology

[0002] In the existing technology, after the grounding bolt and nut assembly is welded to the body parts of the aluminum body, the welding torque needs to be tested. Since the six sides of the bolt are smaller than the truncated cone at the bottom of the nut, it is inconvenient to directly test the bolt with tools such as sockets. The torque test is directly performed on the nut of the grounding bolt and nut assembly. After the test is completed, the nut is loosened and then tightened back to the specified torque, which results in low operation efficiency. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, the purpose of this utility model is to provide a welding torque detection sleeve for grounding bolt and nut assembly.

[0004] This utility model discloses a welding torque testing socket for a grounding bolt and nut assembly, comprising a torque wrench and a combined socket. The torque wrench includes a wrench body and a connector disposed at the front end of the wrench body. The combined socket includes an outer socket, a first split bit, and a second split bit. The upper inner end of the outer socket is provided with a wrench connecting cavity, while the lower inner end of the outer socket is provided with a fixed cavity. The first split bit and the second split bit are disposed in the fixed cavity. The connector is assembled in the wrench connecting cavity of the outer socket, and the first split bit and the second split bit are assembled and securely installed in the fixed cavity. The first split bit and the second split bit are combined internally to form a cylindrical countersunk hole and a hexagonal countersunk hole from top to bottom. The cylindrical countersunk hole is used to avoid the grounding bolt and nut assembly, while the hexagonal countersunk hole mates with the grounding bolt of the grounding bolt and nut assembly.

[0005] The fixed cavity has an inner wall structure that mates with the outer surfaces of the first and second split bits.

[0006] The outer sleeve is a cylindrical structure.

[0007] The connector is a square connector.

[0008] The cross-section of the wrench body is rectangular or circular.

[0009] The first split bit and the second split bit have a symmetrical structure.

[0010] Compared with the prior art, the welding torque detection sleeve of the grounding bolt and nut assembly of this utility model has the following advantages:

[0011] This invention utilizes a split-type screwdriver bit that directly engages with the hexagonal head of the grounding bolt. An external socket further transmits the torque from the wrench to the grounding bolt, enabling direct torque testing. This eliminates the need for tightening and re-tightening or disassembling the grounding nut for welding torque testing, significantly improving the efficiency of welding torque testing for grounding bolt and nut assemblies.

[0017] The following will further elaborate on the welding torque detection sleeve of the grounding bolt and nut assembly of this utility model with reference to specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of this utility model.

[0018] Example 1

[0019] like Figure 1-5 As shown, the welding torque detection socket for the grounding bolt and nut assembly in this embodiment includes a torque wrench 10 and a combined socket 20. The torque wrench 10 includes a wrench body 11 and a connector 12 disposed at the front end of the wrench body 11. The combined socket 20 includes an outer socket 21, a first split bit 24, and a second split bit 25. The upper inner end of the outer socket 21 is provided with a wrench connecting cavity 22, and the lower inner end of the outer socket 21 is provided with a fixing cavity 23. The first split bit 24 and the second split bit 25 are disposed in the fixing cavity 23. The connector 12 is assembled in the wrench connecting cavity 22 of the outer socket 21. The connector 12 is a square connector. In the figure, the cross-section of the wrench body 11 is rectangular, but it can also be circular or other shapes.

[0020] The first split-type screwdriver bit 24 and the second split-type screwdriver bit 25 are assembled and securely installed within the fixed cavity 23. The first split-type screwdriver bit 24 and the second split-type screwdriver bit 25 have a symmetrical structure. Internally, the first split-type screwdriver bit 24 and the second split-type screwdriver bit 25 are combined to form a cylindrical countersunk hole and a hexagonal countersunk hole sequentially from top to bottom. The cylindrical countersunk hole avoids the grounding bolt and nut assembly 31, while the hexagonal countersunk hole mates with the grounding bolt of the grounding bolt and nut assembly 31. The fixed cavity 23 has an inner wall structure that mates with the outer surface of the first split-type screwdriver bit 24 and the second split-type screwdriver bit 25. The outer sleeve 21 has a cylindrical structure. The grounding bolt and nut assembly 31 is welded to the vehicle body part. The outer sleeve is fitted onto the inner split-type screwdriver bit, ensuring a tight fit between the inner split-type screwdriver bit and the outer sleeve, and ensuring the wrench can detect the welding torque.

[0021] For those skilled in the art, the specific embodiments are merely exemplary descriptions of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention are within the protection scope of the present invention.
