Description

Technical Field

[0001] This utility model relates to the field of torque measurement technology, and more specifically, to a welding torque measuring fixture. Background Technology

[0002] Welding of automotive connector nuts is a key process in automobile manufacturing to achieve a rigid connection between the nut and the body, frame, or other components. Its core is to use welding technology to fuse the nut to the surface of the target workpiece, providing a stable threaded connection foundation for subsequent bolt assembly. This directly affects the structural strength, assembly accuracy, and driving safety of the automobile.

[0003] Currently, torque measurement after nut welding is a key testing step to verify welding quality and ensure the reliability of connector assembly. The core is to simulate the tightening process of the welded nut using torque measuring tools to test the nut's performance under specific torque.

[0004] However, the torque measurement of welded nuts is generally carried out manually using handheld measuring tools, which is time-consuming, labor-intensive, and inefficient. To address these issues, a welding torque measurement fixture is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding torque measuring fixture.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A welding torque measuring fixture includes a worktable, a detection component is disposed on the top of the worktable, a workpiece is disposed below the detection component, and a placement component is disposed on one side of the detection component.

[0007] The detection component includes a detection mechanism for detecting the torque of the workpiece.

[0008] The detection mechanism includes a rotary cylinder, the output end of which is connected to a connecting plate, and a detection head is provided at the end of the connecting plate away from the rotary cylinder.

[0013] By adopting the above technical solution, the third electric slide rail can drive the connecting seat to move horizontally, thereby realizing the position adjustment of the workpiece. By controlling the movement of the third electric slide rail, each set of nuts on the workpiece can be aligned with the detection mechanism, improving the detection efficiency. In addition, the design of the clamping mechanism allows the workpiece to run stably during movement, reducing the possibility of detection errors caused by positional deviation. This structure is not only easy to operate, but also greatly reduces manual intervention, providing reliable support for automated detection.

[0014] The present invention is further configured such that: the clamping mechanism includes a mounting plate, the mounting plate is disposed on the top of the connecting seat, and the shape of the mounting plate is L-shaped.

[0016] The present invention is further configured such that: the two sets of grippers are arranged opposite each other, and a workpiece is arranged at the middle position of the two sets of grippers.

[0017] By adopting the above technical solution, the clamping mechanism mainly consists of a mounting plate, a clamping cylinder, and a gripper assembly. The mounting plate adopts an L-shaped structural design, which not only provides structural strength for the connection of the device but also facilitates the installation and arrangement of other components. A clamping cylinder is installed on one side plane of the mounting plate. The cylinder serves as a power source, and its output end is connected to a set of movable grippers. The two sets of grippers are arranged symmetrically and opposite to each other. A space for clamping the workpiece is reserved at the center between the two sets of grippers. When the clamping cylinder is activated, the two sets of grippers can move synchronously towards or away from each other, thereby achieving reliable clamping or release of the workpiece. The entire clamping mechanism has a compact structure and flexible operation.

[0018] In summary, this application includes at least one of the following beneficial technical effects: The third electric slide rail of the placement component can drive the workpiece to move horizontally. Together with the first and second electric slide rails of the detection component, it can achieve the positioning of the detection head in the up, down, left, and right directions. The rotary cylinder drives the detection head to rotate automatically for detection, reducing manual intervention and improving the detection efficiency of nut torque. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] Please see Figures 1-4 The present invention provides the following technical solution: Example 1, see Figure 1 A welding torque measuring fixture includes a worktable 1, a detection component 2 is provided on the top of the worktable 1, a workpiece 3 is provided below the detection component 2, and a placement component 4 is provided on one side of the detection component 2.

[0027] The workpiece 3 can be clamped by the placement component 4, so that the workpiece 3 can be inspected under stable support. A welded nut is placed on top of the workpiece 3, and the workpiece 3 can be inspected by the inspection component 2.

[0028] The specific structure of detection component 2 is as follows: See Figure 2 and Figure 3The detection component 2 includes a detection mechanism 25, which is used to detect the torque of the workpiece 3.

[0029] See Figure 2 and Figure 3 The detection mechanism 25 includes a rotary cylinder 251, the output end of which is connected to a connecting plate 252, and a detection head 253 is provided at the end of the connecting plate 252 away from the rotary cylinder 251.

[0030] When the rotary cylinder 251 is activated, it can drive the connecting plate 252 to rotate, and the detection head 253 can rotate and move under the drive of the connecting plate 252.

[0031] The shape of the detection head 253 is adapted to the shape of the nut on the workpiece 3. The nut can be detected through the detection head 253. A torque sensor is installed on the detection head 253. The torque sensor can directly contact the workpiece 3 and convert the mechanical torque signal into a measurable electrical signal. The detection head 253 can be connected to an external data acquisition system. The data acquisition system includes a data collection module and a data display module. The data collection module can collect the detection data of the torque sensor on the detection head 253 and transmit the relevant collected content to the data display module. The data display module processes the collected data and outputs the relevant processed content in the form of a report.

[0032] The detection component 2 also includes a mounting bracket 22, which is located on the top of the workbench 1. A first electric slide rail 21 is provided on one side of the mounting bracket 22, and a second electric slide rail 23 is provided on the side of the first electric slide rail 21 away from the mounting bracket 22.

[0033] See Figure 2 and Figure 3 The second electric slide rail 23 is slidably connected to the mounting base 24 on the side away from the mounting bracket 22, and the detection mechanism 25 is located at the bottom of the mounting base 24.

[0034] The working principle of the first electric slide rail 21 and the second electric slide rail 23 is that the motor provides power, and the reducer and ball screw convert the rotational motion of the motor into linear motion, which drives the slider on the slide rail to move along the track.

[0035] The first electric slide rail 21 mainly enables the horizontal movement of the second electric slide rail 23, the mounting base 24, and the detection mechanism 25. The second electric slide rail 23 mainly enables the vertical movement of the mounting base 24 and the detection mechanism 25. In practical applications, the first electric slide rail 21 and the second electric slide rail 23 can be used to adjust the up, down, left, and right positions of the detection mechanism 25. When the detection mechanism 25 corresponds to the nut, the detection head 253 cooperates with the nut and starts the rotary cylinder 251. Under the drive of the rotary cylinder 251, the detection head 253 will rotate and move. Under the drive of the detection head 253, the torque of the nut can be detected.

[0036] The specific structure of component 4 is as follows: See Figure 2 and Figure 3 The placement component 4 includes two sets of clamping mechanisms 42, which are located at both ends of the workpiece 3.

[0037] See Figure 2 and Figure 3 The placement component 4 also includes a third electric slide rail 41, which is located on the top of the worktable 1. A connecting seat 43 is slidably connected above the third electric slide rail 41, and two sets of clamping mechanisms 42 are located above the connecting seat 43.

[0038] Since multiple sets of nuts are installed on the top of workpiece 3, the position of workpiece 3 needs to be moved during the inspection process to adjust the position of workpiece 3 to match the position of the inspection mechanism 25, so as to facilitate the inspection of the nuts at other positions of workpiece 3.

[0039] The working principle of the third electric slide rail 41 is to use a motor to provide power, and the rotational motion of the motor is converted into linear motion through a ball screw, which drives the slider on the slide rail to move along the track.

[0040] The third electric slide rail 41 can drive the clamping mechanism 42 and the connecting seat 43 to move horizontally as a whole. Then, the workpiece 3 in the middle position of the two clamping mechanisms 42 moves with it, which can move the position of the nut on the workpiece 3, making it easier to detect the nuts in multiple positions on the workpiece 3 and improving the detection efficiency.

[0041] See Figure 4 The clamping mechanism 42 includes a mounting plate 421, which is disposed on the top of the connecting seat 43, and the shape of the mounting plate 421 is L-shaped.

[0042] See Figure 4 A clamping cylinder 422 is provided on one side of the mounting plate 421, and a set of grippers 423 are connected to the output end of the clamping cylinder 422.

[0043] See Figure 4Two sets of grippers 423 are positioned opposite each other, and a workpiece 3 is positioned in the middle of the two sets of grippers 423.

[0044] The clamping mechanism 42 mainly consists of a mounting plate 421, a clamping cylinder 422, and grippers 423. The mounting plate 421 adopts an L-shaped structural design, which provides structural strength for the connection of the device and facilitates the installation and arrangement of other components. A clamping cylinder 422 is installed on one side plane of the mounting plate 421. The cylinder serves as a power source, and its output end is connected to a set of movable grippers 423. The two sets of grippers 423 are arranged symmetrically and opposite to each other. A space for clamping the workpiece 3 is reserved at the center position between the two sets of grippers 423. When the clamping cylinder 422 is activated, the two sets of grippers 423 can move synchronously towards or away from each other, thereby achieving reliable clamping or release of the workpiece 3. The entire clamping mechanism 42 has a compact structure and flexible operation.

[0045] The working process of clamping mechanism 42 is as follows: The output end of the clamping cylinder 422 is connected to a set of grippers 423. When the clamping cylinder 422 is started, the clamping cylinder 422 can drive the two sets of grippers 423 to move towards each other. When the two sets of grippers 423 move towards each other, the two sets of grippers 423 can clamp the workpiece 3.

[0046] The third electric slide rail 41 of the placement component 4 can drive the workpiece 3 to move horizontally. Together with the first electric slide rail 21 and the second electric slide rail 23 of the detection component 2, the detection head 253 can be positioned up, down, left, and right, reducing the possibility of manually adjusting the position of the workpiece 3 and the detection head 253. The rotary cylinder 251 drives the detection head 253 to rotate automatically for detection, reducing manual intervention and improving the detection efficiency of nut torque.

[0047] Specifically, the clamping cylinder 422 is activated. Driven by the clamping cylinder 422, the two sets of grippers 423 are in a state of separation. The workpiece 3 is then placed in the middle position of the two sets of grippers 423. The clamping cylinder 422 is activated again. Driven by the clamping cylinder 422, the two sets of grippers 423 move towards each other and clamp the workpiece 3. Since there are two sets of clamping mechanisms 42, the two sets of clamping mechanisms 42 can clamp both ends of the workpiece 3.

[0048] The third electric slide rail 41 is activated. Driven by the third electric slide rail 41, the connecting seat 43 and the clamping mechanism 42 move to the lower position of the detection position. At this time, the first electric slide rail 21 is activated. Driven by the first electric slide rail 21, the detection mechanism 25 moves to the upper position of the workpiece 3. Then the second electric slide rail 23 is activated. Driven by the second electric slide rail 23, the detection head 253 of the detection mechanism 25 engages with the nut on the upper position of the workpiece 3. After the nut engages with the detection head 253, the rotary cylinder 251 included in the detection mechanism 25 is activated. Driven by the rotary cylinder 251, the detection head 253 can detect the torque of the nut.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
