Abstract

A rapid torque testing device for aluminum studs includes a first clamping block and a second clamping block. The first clamping block has a first stud relief groove at its front end and a wrench connecting block at its rear end, with connecting holes for connection to a torque wrench. The left and right sides of the second clamping block are higher than its center, and a second stud relief groove is located in its center. The center of the second clamping block is flush with the front end of the first clamping block. The left and right sides of the front end of the first and second clamping blocks are connected and fixed to each other. The first and second stud relief grooves combine to form an octagonal clamping groove, which clamps the octagonal structure at the bottom of the stud. This device solves the problems of existing aluminum stud torque testing processes involving numerous steps, long inspection times, many required tools, and high post-test quality risks.

Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production and manufacturing, specifically to a rapid detection device for the torque of aluminum studs. Background Technology

[0002] Aluminum studs mainly consist of two parts: the stud and the nut. The stud and nut are secured by threads. The nut diameter is 16.5mm, and the octagonal section at the bottom, used for torque measurement, is 15mm. Because the nut diameter is larger than the octagonal section, the socket cannot be directly installed from the top for measurement; the nut must be removed. Furthermore, after welding, the octagonal section is approximately 7mm from the part surface. Since the insert head of a typical open-end torque wrench is 8-12mm thick, it's impossible to insert the stud from the side without removing the nut to measure the torque.

[0003] The existing method for measuring the torque of aluminum studs after welding mainly involves three steps: First, use a wrench to remove the nut from the aluminum stud and place it in the designated position. Second, use a torque wrench and a special socket to measure the torque of the stud. Third, screw the nut back onto the stud and then use a torque wrench to tighten the nut to the required torque.

[0004] The measurement process is complex and time-consuming. Furthermore, there is a risk of forgetting to tighten the nut after measuring the stud torque, which could lead to assembly problems at the client end. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rapid testing device for the torque of aluminum studs. This device solves the problems of numerous steps, long inspection time, many required tools, and high quality risks associated with existing aluminum stud torque testing processes.

[0006] The purpose of this utility model is achieved by the following solution: A rapid torque detection device for aluminum studs, comprising a first clamping block and a second clamping block. The front end of the first clamping block is provided with a first stud relief groove, and the rear end of the first clamping block is provided with a wrench connecting block. The wrench connecting block is provided with a connecting hole for connecting with a torque wrench. The left and right sides of the second clamping block are higher than the middle part, and the center of the second clamping block is provided with a second stud relief groove. The middle part of the second clamping block is flush with the front end of the first clamping block. The left and right sides of the front end of the first clamping block are connected and fixed to the left and right sides of the front end of the second clamping block. The first stud relief groove and the second stud relief groove are combined to form an octagonal clamping groove, which clamps the octagonal structure at the bottom of the stud.

[0007] The first clamping block and the second clamping block are provided with connecting through holes on the left and right sides of their front ends. Connecting pins pass through the connecting through holes to connect and fix the first clamping block and the second clamping block.

[0008] The connection hole is a 1 / 4 adapter connection hole.

[0009] The advantages of this invention are: the rapid aluminum stud torque testing device does not require disassembling the nut during the testing process, enabling rapid measurement of the stud torque of projection-welded aluminum studs. Furthermore, since the nut does not need to be disassembled, it avoids the quality risks associated with loose or improperly installed nuts. The rapid aluminum stud torque testing device has a simple structure and is easy to operate, reducing the operational difficulty for employees. It also uses a 1 / 4" interface, directly compatible with torque wrenches ranging from 0-30 N.m, requiring no special tools and exhibiting strong versatility. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the first clamping block structure; Figure 3 This is a schematic diagram of the second clamping block structure. Detailed Implementation

[0011] like Figures 1 to 3 As shown, a rapid torque testing device for aluminum studs includes a first clamping block 1 and a second clamping block 2. The front end of the first clamping block 1 is provided with a first stud relief groove 1-1, and the rear end of the first clamping block 1 is provided with a wrench connecting block 1-2. The wrench connecting block 1-2 is provided with a connecting hole 1-3 for connecting to a torque wrench; the connecting hole 1-3 is a 1 / 4" adapter connecting hole. The left and right sides of the second clamping block 2 are higher than the middle part, and the center of the second clamping block 2 is provided with a second stud relief groove 2-1. The middle part of the second clamping block 2 is flush with the front end of the first clamping block 1. The left and right sides of the front end of the first clamping block 1 are connected and fixed to the left and right sides of the front end of the second clamping block 2. Connecting through holes are provided on the left and right sides of the front end of the first clamping block 1 and the second clamping block 2, and connecting pins 3 pass through the connecting through holes to connect and fix the first clamping block 1 and the second clamping block 2. The first stud relief groove 1-1 and the second stud relief groove 2-1 combine to form an octagonal clamping groove. The octagonal clamping groove clamps the octagonal structure at the bottom of the stud to prevent slippage when measuring torque and improve the stability of the measurement.

[0012] First, install the first clamping block 1 onto the torque wrench (the torque wrench head is a 1 / 4" adapter). Then, clamp the first clamping block 1 into the octagonal position under the stud. Next, rotate the second clamping block 2 to fit the shape of the octagonal structure at the bottom of the stud. Insert the connecting pin to secure it. Rotate the torque wrench to complete the torque measurement. After completion, rotate the torque wrench in the opposite direction to remove the connecting pin, and then remove the torque wrench to complete the measurement.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
