[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The calibration of ordinary torque wrenches is based on the relevant requirements of JJG707-2014 "Verification Procedure for Torque Wrenches". Calibration of ordinary torque wrenches is usually completed in experiments at metrology institutions. Torque calibration is achieved using a torque wrench calibrator. The calibration of electric and pneumatic torque wrenches is based on JJF1610-2017 "Calibration Specification for Electric and Pneumatic Torque Wrenches". The calibration of electric and pneumatic torque wrenches is relatively complex, requiring an external power supply or air source. The electric and pneumatic wrench connectors are connected to a standard torque sensor, and high-thrust and low-thrust simulators are needed to simulate calibration under dynamic conditions. To meet the above testing and calibration standards and enable on-site torque testing and calibration within the wrench-using factory area, a mobile torque testing platform is proposed in this embodiment.

[0021] like Figures 1-3 The diagram shows the overall structure of the mobile torque testing platform proposed in this embodiment. The platform's operating console 1 is equipped with a torque meter 2, a display 3, and a human-machine interface screen 4. A computer host 5 and a controller 6 are located below the operating console 1. Additionally, the operating console 1 is equipped with a handheld torque meter 9 and a barcode scanner 10 for scanning wrench information codes. The barcode scanner 10 establishes a wireless data transmission connection with the computer host 5. The handheld torque meter 9 can easily and quickly measure torque. Before torque testing, the barcode scanner 10 scans the QR code identification information affixed to the wrench to be tested, ensuring that subsequent torque testing data corresponds to the wrench's identification information, effectively improving the efficiency and accuracy of wrench torque inspection and management. The torque meter 2's detection port is exposed on the upper surface of the operating console 1. The torque meter 2 is wiredly connected to the controller 6. The display 3, the human-machine interface screen 4, and the controller 6 are all connected to the computer host 5 for signal data transmission. The display 3 and the human-machine interface screen 4 are mounted on the outer side of the middle of the operating console 1 via a rotating bracket 11.

[0022] The mobile torque testing platform adopts a box-type frame structure. The operating platform 1 is located at the top of the box-type frame structure, and the sides and bottom of the box-type frame structure are enclosed by panels. The computer host 5 and controller 6 are located at the bottom inside the box-type frame structure. To facilitate the inspection and maintenance of the equipment inside the mobile torque testing platform, cabinet doors can be installed on the front and back sides of the box-type frame structure when setting up the panels around the sides and bottom of the box-type frame structure.

[0023] The mobile torque testing platform is equipped with the aforementioned computer host 5 and controller 6, as well as a battery 12 that provides power to various electrical devices. In addition, it is also equipped with a fixture placement rack 16. The mobile torque testing platform adopts a box-type frame structure with an intake fan 13 on one side and an exhaust fan 14 and an external power socket 15 on the other side.

[0024] Controller 6 is a 7-bit bus controller, outputting I / O signals for control. Controller 6 is responsible for cable switching, while range selection is manually performed by the operator. Controller 6 is mounted on the lower surface of the operating table 1 and connected to the sensors on both the handheld torque meter 9 and the torque meter 2. The handheld torque meter 9 can be an Atlas Copco STA6000 model torque meter.

[0025] like Figure 2 or Figure 3 ,as well as Figure 4 and Figure 5 As shown, it is worth mentioning that the torque detector 2 in this embodiment includes a dynamic torque detector 21 disposed on one side of the operating table 1 and a static torque detector 22 disposed on the other side of the operating table 1.

[0026] The dynamic torque meter 21 is used to measure the torque (alternating or transient torque) that changes in real time under rotation, and can continuously measure torque fluctuations when the shaft is rotating at high speed.

[0027] The dynamic torque detector 21 includes a drive motor 211, a torque sensor 212, and a rotating rod 213. The output end of the drive motor 211 is fixedly connected to the rotating rod 213. The upper end of the rotating rod 213 passes through the table surface of the operating platform 1, and the lower end is mounted on the rotating shaft 214 of the frame 215. The upper end of the rotating rod 213 can be connected to a wrench to transmit the torque force of the wrench. The upper end of the frame 215 is fixedly mounted on the operating platform 1. The torque sensor 212, used to measure torque, is located on one side of the drive motor 211 and is connected to the controller 6 via a plug-in cable 216.

[0028] The static torque meter 22 is used to measure torque at rest or with slow changes (steady-state torque). It is used to measure torque that does not change rapidly over time, such as the holding torque after tightening a bolt, static load testing, etc. The static torque meter 22 is based on the strain gauge bridge principle. The rotating shaft on the static torque meter 22 does not rotate or rotates at a low speed, and the signal can be directly led out through wires. Its structure is simpler than the dynamic torque meter 21, and the specific structural settings of the dynamic torque meter 21 will not be described in detail in this solution. A clamp 7 for restraining the wrench is installed above the static torque meter 22.

[0029] like Figure 6As shown, the fixture 7 in this solution is mainly used for fixing and constraining the tooling. The fixture 7 consists of a movable clamping block 71, a reverse threaded rod 72, a constraint rod 73, a support plate 74, and a handle 75. Two movable clamping blocks 71 are provided, with semi-circular grooves at the ends. The semi-circular grooves of the two movable clamping blocks 71 are arranged opposite each other to form a circular clamping area. Rollers 76 are provided inside the semi-circular grooves. The other end of the movable clamping block 71 is provided with a constraint hole and a threaded hole. The constraint hole passes through the constraint rod 73, and the threaded hole is threaded to the reverse threaded rod 72. The two ends of the reverse threaded rod 72 and the constraint rod 73 are rotatably mounted on the support plate 74. A handle 75 is installed at one end of the reverse threaded rod 72. The reverse threaded rod 72 is symmetrical about the middle and has opposite thread patterns on both sides. When the reverse threaded rod 72 rotates, the movable clamping blocks 71 can move in opposite directions, flexibly adjusting the size of the circular clamping area formed by the semi-circular grooves of the two movable clamping blocks 71.

[0030] like Figure 7 As shown, a manual crank arm 8 for driving the wrench is provided on one side of the operating table 1. It should be noted that the manual crank arm 8 is not limited to being fixed on one side of the operating table 1; its installation position on the operating table 1 can be flexibly adjusted according to usage. This embodiment only illustrates one specific case.

[0031] The manual crank arm 8 includes a slide rail 81, a slider 82, and limiting rods 83. One side of the slide rail 81 is inserted and installed on the box-type frame structure of the mobile torque detection platform. The slider 82 is slidably disposed on the slide rail 81. Two limiting rods 83 are symmetrically arranged along the axis of the slider 82 and are installed on the top of the slider 82. The sliding method between the slide rail 81 and the slider 82 can be achieved by having a rotating screw threadedly connected to the slider 82 inside the slide rail 81. One end of the rotating screw is fixedly connected to a rotating handle 84. By rotating the rotating handle 84, the slider 82 moves smoothly along the rotating screw and the slide rail 81. The handheld area of ​​the wrench to be tested is placed between the two limiting rods 83. The torque output end of the wrench is connected to the torque detector 2.

[0032] This mobile torque testing platform allows for the calibration of different types of torque wrenches on a single platform. It can perform torque testing on ordinary torque wrenches (pointer type, analog type, dial type), electric, and pneumatic torque wrenches, with a torque measurement range of 0.1 Nm to 50 Nm. According to JJG707-2014 "Verification Procedure for Torque Wrenches" and JJF1610-2017 "Calibration Specification for Electric and Pneumatic Torque Wrenches," the testing accuracy is 0.5 grade. Its high degree of integration allows companies to meet their needs for periodic calibration and daily accuracy monitoring of torque wrenches. It is also suitable for use in complex working conditions.

[0033] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology. The above description is only a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
