Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupling torque measurement technology, specifically a coupling torque measurement device. Background Technology
[0002] Couplings, as key components in mechanical transmission systems, are widely used in various rotating equipment. Determining their torque transmission performance is crucial for ensuring the safety and reliability of equipment operation. Currently, coupling torque measurement typically employs a torque meter, whose typical structure includes a load cell, coupling, dynamic torque sensor, the coupling under test, and a drive motor (such as a three-phase asynchronous motor). During testing, the coupling under test must be rotated at high speed to measure torque, simulating its performance under actual operating conditions.
[0003] However, existing coupling torque measuring devices lack effective protective measures. During high-speed rotation testing, if the coupling accidentally disengages due to bolt breakage, grease splashing, or connection failure, metal fragments, grease, or other parts may be ejected at extremely high speeds, causing serious personal injury to operators.
[0004] Therefore, we propose a coupling torque measuring device. Utility Model Content

Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] This embodiment is a coupling torque measuring device.
[0025] like Figure 1-4 As shown, the device includes a processing table 1, a coupling torque measuring instrument 2 fixedly mounted on the upper outer surface of the processing table 1, a raised platform 3 fixedly mounted in the middle of the upper outer surface of the processing table 1, a protective structure 4 on the upper part of the raised platform 3, and a drive tilting structure 5 on one side of the protective structure 4 and the processing table 1. The protective structure 4 includes a transparent protective cover 6, a groove 7, an L-shaped connecting arm 8, a drive shaft 9, a support arm 10, a drive arm 11, and a connecting shaft 12. The drive tilting structure 5 includes a collar 13, a hydraulic rod 14, a connecting ring 15, a rotating shaft 16, and a fixed arm 17. The transparent protective cover 6 is located on the upper part of the raised platform 3 and covers the outside of the coupling to be measured in the coupling torque measuring instrument 2.
[0026] There are two sets of grooves 7, L-shaped connecting arms 8, and support arms 10. Two sets of grooves 7 are located at the lower middle of the outer surfaces at both ends of the transparent protective cover 6. Two sets of L-shaped connecting arms 8 are fixed between the left and right sides of the bottom of the front outer surface of the transparent protective cover 6 and the outer walls at both ends of the drive shaft 9. Two sets of support arms 10 are fixed to the upper part of the front outer surface of the processing table 1, and are installed on the outer walls at both ends of the drive shaft 9. Bearings are provided between the drive shaft 9 and the support arms 10, and the drive shaft 9 is rotatably connected to the support arms 10 through the bearings. One side of the outer surface of the drive arm 11 is fixed to the right side of the outer surface of the drive shaft 9. The connecting shaft 12 is fixed to the front end of the right outer surface of the drive arm 11; the fixed arm 17 is fixed to one side of the bottom of the front outer surface of the processing table 1, and the rotating shaft 16 is fixed to the front end of one side of the fixed arm 17; the collar 13 is fixed to the upper outer surface of the piston rod in the hydraulic rod 14, and the connecting ring 15 is fixed to the lower outer surface of the cylinder in the hydraulic rod 14; a bearing is provided between the collar 13 and the connecting shaft 12, and the collar 13 is rotatably connected to the outer wall of the connecting shaft 12 through the bearing; a bearing is provided between the connecting ring 15 and the rotating shaft 16, and the connecting ring 15 is rotatably connected to the outer wall of the rotating shaft 16 through the bearing.
[0027] It should be noted that this utility model is a coupling torque measuring device. The coupling torque measuring instrument 2 described in this article belongs to the prior art and can be effectively known to those skilled in the art. Specific details will not be elaborated further. The self-contained drive-flipping structure 5 and protective structure 4 are driven by a hydraulic rod 14 in the drive-flipping structure 5, which drives the transparent protective cover 6 in the protective structure 4 to flip and open. The operation of the hydraulic rod 14 causes the piston rod to extend, which in turn causes the drive arm 11 to swing. The drive arm 11 then drives the drive shaft 9 to rotate. The drive shaft 9, through an L-shaped connecting arm 8, causes the transparent protective cover 6 to flip around the drive shaft 9. When measuring the coupling, the operation of the hydraulic rod 14 causes the transparent protective cover 6 to flip and cover the outside of the coupling to be measured, improving protection. After the measurement, the hydraulic rod 14 causes the piston rod to retract, thereby causing the transparent protective cover 6 to flip and open for easy operation.
