Description

Technical Field

[0001] The utility model relates to the technical field of torque wrench detection, in particular to a torque wrench calibration platform and a torque wrench detection device. Background Art

[0002] A torque wrench is a tool that uses torque to tighten bolts and nuts. It can be divided into electric torque wrenches, pneumatic torque wrenches, hydraulic torque wrenches and manual torque wrenches according to the power source. Among them, torque wrenches such as electric torque wrenches, pneumatic torque wrenches and hydraulic torque wrenches can automatically control torque and are automatic construction tools for assembling threaded parts and bolts. Torque wrenches are widely used in automobile manufacturing and maintenance, aerospace, industrial assembly, bolted and welded structure bridge erection, factory facility installation and other fields, as well as occasions with strict requirements on the torque and axial tension of threaded fasteners.

[0003] Torque wrenches need to be calibrated before leaving the factory and after extended use to ensure the accuracy and stability of the torque output. Current torque wrench calibration is typically performed using calibration equipment, which includes a calibration platform, a torque sensor, and a stopper mounted on the platform. During calibration, the head of the torque wrench is docked against the torque sensor, and the handle of the torque wrench is placed against the stopper. The torque wrench is then started, causing the head of the torque wrench to rotate the torque sensor while the handle remains in contact with the stopper. The torque sensor then compares the torque wrench's output torque with a known standard torque, completing the calibration.

[0004] Currently, torque wrenches come in a variety of specifications, and the handle length of each specification is different. Therefore, multiple sets of equipment are required to calibrate torque wrenches of various specifications, resulting in high production costs for enterprises. Utility Model Content

[0033] Refer to the following Figures 1 to 3 The torque wrench calibration platform and torque wrench detection equipment provided by the utility model are described.

[0034] The torque wrench testing device includes a testing device body and a torque wrench calibration platform. The testing device body is a device capable of performing any test on the torque wrench, such as an appearance inspection platform or a power-on inspection platform. This embodiment uses the appearance inspection platform as an example. The torque wrench calibration platform is located on one side of the appearance inspection platform and is used to calibrate the torque wrench.

[0035] It should be noted that the torque wrench calibration platform is designed to be compatible with the calibration of torque wrenches with a variety of different handle lengths, so as to reduce the number of torque wrench calibration platforms that the enterprise needs to equip to a certain extent, thereby reducing the cost of the enterprise. Please refer to the following embodiments for the exemplary structure of the torque wrench calibration platform.

[0036] Example 1

[0037] Reference Figures 1 to 3 The torque wrench calibration platform includes a platform body 100, a stopper 200 and a torque sensor. The stopper 200 and the torque sensor are both arranged on the platform body 100, and the position of the stopper 200 can be adjusted along the longest straight path 103 on the platform body 100; the torque sensor is located on one side of the longest straight path 103.

[0038] Specifically, the platform body 100 in this embodiment is a square plate and is arranged horizontally, and its longest straight path 103 is the diagonal of the square plate; in some other embodiments, the platform body 100 can also be a circular plate or other polygons, and can be tilted at a certain angle.

[0039] In addition, at least three support members 300 are provided at the bottom of the platform body 100 to support the platform body 100, leaving a gap between the platform body 100 and the components below it to facilitate the removal of the platform body 100. In addition, the torque sensor can be made to protrude from the bottom of the platform body 100 to accommodate different types of torque sensors.

[0040] For example, in this embodiment, there are four support members 300, which are distributed at the four corners of the platform body 100. Each support member 300 is arranged in a truncated cone shape, and the diameter of the support member 300 gradually decreases from top to bottom.

[0041] In addition, each support member 300 is detachably connected to the platform body 100, which is specifically a threaded connection in this embodiment, that is, the support member 300 is threadedly connected to the platform body 100, so that when some support members 300 are worn or otherwise damaged, the damaged support members 300 can be replaced.

[0042] Furthermore, the platform body 100 is provided with multiple mounting areas evenly distributed along the longest straight path 103, and the retaining members 200 are detachably connected to the mounting areas. By evenly distributing the multiple mounting areas along the longest straight path 103 on the platform body 100, a greater number of mounting areas can be provided while maintaining the size of the platform body 100 and the spacing between adjacent mounting areas. This increases the adaptability of torque wrench handle lengths and minimizes the number of torque wrench calibration platforms required by the enterprise.

[0043] Specifically in this embodiment, each mounting area is provided with a connection hole 101. The retaining member 200 is cylindrical and provided with a connecting rod 201, which is threadedly connected to the connection hole 101. This achieves a detachable connection between the retaining member 200 and the platform body 100, making it easy to adjust the retaining member 200 to a desired position. The threaded connection also has a certain self-locking effect, which prevents the retaining member 200 from loosening during operation.

[0044] In addition, it should be noted that a positioning ring groove 1011 is provided at the top of each connecting hole 101 in this embodiment. In this embodiment, the diameter of the retaining member 200 is larger than the diameter of the connecting rod 201, and the bottom end of the retaining member 200 cooperates with the positioning ring groove 1011 plug-in, thereby utilizing the retaining member 200 with a larger diameter to withstand the radial force of the torque wrench acting on the retaining member 200, making the retaining member 200 work more stably.

[0045] Optionally, in some other embodiments, the blocking member 200 may be provided in a block shape; or the connecting rod 201 may be directly plugged into the connecting hole 101 .

[0046] In addition, in some other embodiments, a connecting column may be provided in the installation area, and a connecting groove may be provided on the retaining member 200, and the connecting column and the connecting groove may be plugged in or threadedly connected; plugging or threading the connecting column and the connecting groove may also realize a detachable connection between the retaining member 200 and the platform body 100.

[0047] Furthermore, a positioning hole 102 is provided on the platform body 100, and the torque sensor is positioned inside the positioning hole 102. In this embodiment, there are three positioning holes 102, and the three positioning holes 102 are respectively a hexagonal through hole, a quadrilateral through hole and a hexagonal countersunk hole, so as to adapt to different types of torque sensors.

[0048] Based on the above content, when the torque wrench calibration platform is used, the position of the torque sensor is first determined, and the torque sensor is installed at the positioning hole 102, and then the position of the stopper 200 is adjusted according to the size and length of the torque wrench handle; then the head of the torque wrench is docked with the torque sensor, the tail end of the torque wrench handle is fitted with the stopper 200, and the rotation direction of the torque wrench is set; finally, the tightening operation is started, and the output torque of the torque wrench is compared with the known standard torque through the torque sensor, thereby completing the calibration of the torque wrench. The entire calibration process realizes the precise control and recording of the torque, ensuring the accuracy and traceability of the calibration operation.

[0049] Example 2

[0050] This embodiment differs from the first embodiment in that a guide rail is provided on the platform body 100 of this embodiment. The guide rail is arranged along the longest straight path 103. A slider is slidably provided on the guide rail, and the slider can be positioned at any position on the guide rail. The specific positioning method can adopt any method in the prior art, such as threaded connection of the slider with a bolt and abutment against the guide rail. The bottom end of the retaining member 200 is connected to the slider. The sliding of the slider allows for stepless adjustment of the position of the retaining member 200, thereby increasing the adaptability range of the torque wrench length.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
