Description

Technical Field

[0001] This utility model belongs to the field of torque calibration technology, specifically a torque flange calibration device. Background Technology

[0002] Torque calibration is a crucial step in workpiece production to ensure the accuracy of measurement results. It involves calibrating the measuring equipment or system to establish an accurate correspondence between its output and the true value. For example, in the production of flanges, the produced flanges need to be subjected to torque calibration tests to obtain the maximum torque limit of the flange. Therefore, a torque flange calibration device is required.

[0003] For example, CN111829722A discloses a torque flange calibration device, comprising an adjusting weight, an upper arm support, an upper arm, a lower arm, an arm adjustment assembly, an upper arm weight support rod, and a lower arm weight support rod. The adjusting weight is mounted on the upper arm and can move along the length of the upper arm. The upper arm support is used to fix it to an external support device. The upper arm is hinged to the upper arm support and can rotate freely on the upper arm support. Both ends of the upper arm are respectively fixedly connected to one end of the upper arm weight support rod and one end of the arm adjustment assembly. The upper arm is connected to the upper arm weight support rod and the lower arm... After the calibration device is installed and the adjustment components are perpendicular to each other, the upper arm and lower arm are parallel by adjusting the length of the lower arm adjustment block support rod and the upper arm adjustment block support rod screwed into the adjustment block. Adjusting weights are used to adjust the level of the entire parallel arm torque flange calibration device system to ensure that the calibration device is level. Then, calibration weights are placed on the upper arm weight tray and the lower arm weight tray. The calibration weights on the upper arm weight tray and the lower arm weight tray apply downward force to the upper arm and the lower arm respectively at the same time. The reading of the torque flange to be calibrated is read at this time to complete the calibration.

[0004] Current torque flange calibration devices typically involve placing the flange in the working position and manually turning the knob on the flange. However, in actual use, manual turning may not necessarily bring the flange to its maximum torque limit, leading to inaccurate results. Furthermore, these devices are not very versatile and are inconvenient for use with flanges of different sizes. Therefore, a torque flange calibration device is proposed to address these issues.

[0006] The technical solution adopted by this utility model to solve its technical problem is a torque flange calibration device, including a base plate. A torque calibration component is installed at the top of one end of the base plate. An elevated platform is provided on one side of the base plate, and a clamping component is installed on the elevated platform. The torque calibration component includes a calibration plate. Two fixing plates are symmetrically installed at the top of the calibration plate. The two fixing plates have mounting grooves. A hollow shaft is installed in the mounting groove, and a threaded rod is installed in the hollow shaft. Two mounting frames are slidably installed on the threaded rod.

A mounting block is installed at the top of the telescopic rod of the multi-stage telescopic cylinder, and a force measuring lever is installed on the mounting block. By fixing the flange between the force measuring levers, the flange can be turned to obtain its maximum torque limit.

[0007] Preferably, one of the fixed plates has a placement plate on its outer side wall, and a No. 1 motor is installed at the top of the placement plate. The output end of the No. 1 motor is connected to a threaded rod through a coupling, which can adjust the distance between the measuring levers and improve the applicability of the device.

A through slot is provided at the top of the crossbeam of the elevated platform, and the first electric telescopic cylinder is installed in the through slot. An mounting plate is installed at the top of the telescopic rod of the first electric telescopic cylinder. A second rotating shaft is provided on the mounting plate. An mounting ring is installed at the top of the second rotating shaft. Multiple mounting holes are provided on the mounting ring, and a second electric telescopic cylinder is installed in each of the multiple mounting holes. The top of the telescopic rod of the multiple second electric telescopic cylinders is equipped with a gripper, which can drive the flange to rotate after it is fixed.

[0009] Preferably, a second motor is installed at the top of the mounting plate, and the output end of the second motor is connected to a second rotating shaft via a coupling. A telescopic cylinder controller is installed on the outer wall of the mounting ring to control multiple electric telescopic cylinders.

[0010] Preferably, the gripper is located on the inner wall of the mounting ring, the mounting ring is located directly above the calibration plate, a control panel is installed on the other side of the base plate, and table legs are installed at the bottom of the base plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a torque calibration component, fixes the flange in the working position before operation. The first electric telescopic cylinder is controlled to lift and lower by the telescopic cylinder controller. The second electric telescopic cylinder is started to drive the gripper to clamp the flange. Under the action of the second motor, the flange is driven to rotate. Compared with the traditional torque calibration device, it can make the flange reach the maximum torque limit and improve the accuracy of the device.

[0014] 2. This utility model, by setting up a control panel, allows the measured data to be sensed by a torque sensor when working on the flange. The torque sensor first senses the applied torque and converts it into an electrical signal, which is then transmitted to the control panel. The control panel receives the sensor signal and processes and calibrates it according to preset standards. The distance between multiple force-measuring levers is adjusted by a multi-stage telescopic cylinder, and with the cooperation of a No. 1 motor, the flange can be fixed between multiple force-measuring levers. This combination enables easy operation on flanges of different sizes and improves the working efficiency of the device. Attached Figure Description

[0028] Working Principle: Existing torque flange calibration devices are not very versatile and inconvenient for working with flanges of different sizes. In this solution, the present invention uses a control panel 28. When working with a flange, the measured data is sensed by the F2IS-20000N torque sensor 10, which converts the torque applied to the flange into an electrical signal and transmits it to the control panel 28. The control panel 28 receives the sensor signal and processes and calibrates it according to a preset standard. The distance between multiple force-measuring levers 18 is adjusted by a multi-stage telescopic cylinder 16, and with the cooperation of a motor 12, the flange can be fixed between the multiple force-measuring levers 18. This combination enables easy operation of flanges of different sizes and improves the working efficiency of the device.

[0029] Existing torque flange calibration devices typically involve placing the flange in the working position and manually turning the knob on the flange. However, in actual use, manual turning may not necessarily bring the flange to its maximum torque limit, leading to inaccurate results.
