Description

Technical Field

[0001] The utility model relates to the technical field of torque limiters, in particular to a detection device for a torque limiter. Background Art

[0002] The torque limiter's primary function is to connect the engine and generator, transmitting engine torque. When resonance or impact occurs between the engine and generator, the torque limiter slips, protecting generator components from damage caused by excessive torque. It also filters and attenuates engine vibration, preventing unacceptable vibration and noise from the generator. The driven plate's damper spring attenuates engine vibration, while the internal friction plate limits excess torque, protecting the generator.

[0003] The Chinese utility model patent with publication number CN221883041U discloses a friction torque limiter detection device. The method comprises the following steps: selecting a mounting shaft of appropriate size according to the torque limiter model, inserting a clamping column into the corresponding clamping slot, and then installing the torque limiter on the mounting shaft; moving the slider along the sliding slot, and the slider drives the annular frame and the insert plate to move to the position of the torque limiter; moving the insert plate, and installing the insert plate and the torque limiter together through external bolts, and rotating the positioning bolts to fix the insert plate; controlling the operation of the external hydraulic cylinders during detection, with one hydraulic cylinder driving the ear plate to move up and the other hydraulic cylinder driving the ear plate to move down, so that the two ear plates 71 drive the fixed shaft to rotate through the driving shaft, and the fixed shaft drives the mounting shaft to rotate through the clamping column, thereby detecting at what load the mounting shaft and the torque limiter will slip.

[0004] Although the device can effectively detect the load at which the torque limiter will slip, in actual use, when a large number of torque limiters need to be tested, many steps in the testing process still require manual intervention, and it is not convenient enough. The continuity of the test is poor, resulting in low detection efficiency. Summary of the Invention

[0028] It should be noted that several placement slots 31 are evenly distributed circumferentially on the top of the retrieval disk 3, the diameters of the limiting column 32 and the positioning column 42 are the same as the inner diameter of the torque limiter, the shape and size of the first card key 33 and the second card key 43 are the same as the shape and size of the keyway inside the torque limiter, and the limiting column 32, the positioning column 42, the placement slot 31 and the torque limiter are coaxially arranged; the servo motor 2 and the torque motor 41 are electrically connected to the control system 5, and the control method of the control system 5 and the control circuit for realizing fully automatic production belong to the prior art and can be realized by programming by technical personnel in this field. It is common knowledge in this field. Therefore, this application no longer explains the control method and module in detail, and no detailed description is made here.

[0029] Specifically, the torque limiter of the torque load to be tested is placed in the placement slot 31, and the keyway inside the torque limiter is aligned with the first card key 33, so that the inner wall of the torque limiter near the bottom is clamped on the side of the limit column 32, and the keyway is clamped on the side of the first card key 33. Through the cooperation of the lifting assembly, the torque limiter at the bottom of the opposing torque motor 41 is driven to rise, so that the inner wall of the torque limiter near the top is clamped on the side of the positioning column 42, and the keyway is clamped on the side of the second card key 43. Through the cooperation of the control system 5, the torque motor 41 is controlled to gradually increase the output torque.

[0031] It should be noted that the number of hydraulic cylinders 6 and top plates 61 is the same as the number of placement slots 31, and the top plate 61 is coaxially arranged with the placement slot 31; the hydraulic cylinder 6 is controlled by an external hydraulic control system 5, which is powered by an electric motor and uses a hydraulic pump to convert mechanical energy into pressure to push the hydraulic oil and control various valves to change the flow direction of the hydraulic oil, thereby pushing the hydraulic cylinder 6 to perform actions of different strokes and directions. The specific structure is a universal standard part or a part known to those skilled in the art, and will not be described in detail here; when the torque limiter to be tested is installed on the side of the limit column 32, its bottom can be overlapped on the top of the top plate 61, and after facing the bottom of the torque motor 41, the hydraulic cylinder 6 at the bottom of the retrieval disk 3 is controlled to extend, pushing the top plate 61 in the placement slot 31 to rise, so that it can drive the torque limiter to rise synchronously, and be positioned and connected with the positioning column 42 at the output end of the torque motor 41, thereby completing the clamping and positioning operation of the torque limiter to be tested, thereby improving the degree of automation.

[0032] In some embodiments, a robotic arm 7 for transporting and placing the torque limiter is installed on the top of the workbench 1; the robotic arm 7 is electrically connected to the control system 5; through the setting of the robotic arm 7, the torque limiter to be tested can be grabbed and placed in the placement slot 31, and the torque limiter after testing can also be taken out from the placement slot 31, thereby realizing fully automatic production control of the equipment and improving the intelligence level of the equipment.

[0033] In some embodiments, a bearing seat 8 for receiving the comprehensive load of the retrieval disk 3 is installed between the workbench 1 and the retrieval disk 3, and the bearing seat 8 is coaxially arranged with the retrieval disk 3; through the setting of the bearing seat 8, the output end of the servo motor 2 can be rotationally limited, and the comprehensive load of the retrieval disk 3 on the top of the workbench 1 can be received, thereby playing a supporting role.

[0034] like Figure 3 As shown, in some embodiments, a plurality of supporting legs 9 are fixed to the bottom of the workbench 1; the arrangement of the plurality of supporting legs 9 can provide support for the workbench 1.

[0035] In some embodiments, a plurality of anti-skid pads 91 are fixed to the bottom of the plurality of support legs 9; the provision of the anti-skid pads 91 can provide an anti-skid and stable effect during support.

[0036] When the present invention is used, the torque limiter to be tested is grabbed by the mechanical arm 7 and placed in the placement groove 31, and the key groove inside the torque limiter is aligned with the first card key 33, so that the inner wall of the torque limiter near the bottom is clamped on the side of the limit column 32, and the key groove is clamped on the side of the first card key 33, and the hydraulic cylinder 6 at the bottom of the retrieval plate 3 is controlled to extend, pushing the top plate 61 in the placement groove 31 to rise, so that it can drive the torque limiter to rise synchronously, drive the torque limiter at the bottom of the opposite torque motor 41 to rise, and make the inner wall near the top of the torque limiter clamped on the fixed column 32. On the side of the position column 42, the key slot is connected to the side of the second key 43. Through the cooperation of the control system 5, the torque motor 41 is controlled to gradually increase the output torque.
