Description

Technical Field

[0001] This utility model belongs to the field of reduction gearbox technology, specifically relating to an automated detection device for the output shaft of a reduction gearbox. Background Technology

[0002] Gearboxes are commonly used transmission components in mechanical equipment. Their output shafts, as key components for power output, directly affect the performance and service life of the entire transmission system due to their installation height and rotational torque. Currently, the inspection of gearbox output shafts is mostly done manually, resulting in low inspection efficiency, high labor intensity, and unstable inspection accuracy. In particular, the installation height and rotational torque of the output shaft, two critical parameters, need to be inspected separately at different workstations, increasing inspection time and equipment costs.

[0003] Currently, there is a lack of existing technologies that can simultaneously automate the detection of output shaft mounting height and rotational torque, making it difficult to meet the demands of modern production lines for high-efficiency and high-precision detection. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an automated detection device for the output shaft of a reduction gearbox that has a reasonable structure, high detection efficiency, and stable accuracy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automated detection device for the output shaft of a reduction gearbox, comprising a worktable, a turntable, multiple carriers, an output shaft height detection mechanism, and an output shaft torque detection mechanism. The turntable is rotatably mounted on the worktable and driven by a stepper motor. The multiple carriers are distributed circumferentially along the turntable and are used to transport the output shaft of the reduction gearbox to be tested. The output shaft height detection mechanism is mounted on the worktable and is used to detect the installation height of the output shaft of the reduction gearbox on the carriers. The output shaft torque detection mechanism is mounted on the worktable and is used to detect the output shaft height of the reduction gearbox. The output shaft torque detection mechanism includes a support plate on a workbench, a slide plate that can slide longitudinally on the support plate, a servo motor on the slide plate, a torque sensor at the output end of the servo motor, a sleeve connected to the lower end of the torque sensor, and a clamping mechanism on the workbench corresponding to one side of the sleeve. The support plate is provided with a first cylinder for driving the slide plate to slide longitudinally back and forth. The bottom of the sleeve is provided with a groove that mates with the upper end of the output shaft. The clamping mechanism is used to apply an axial clamping force to the bearing on the output shaft during torque detection, so that the bearing is pressed tightly onto the carrier.

[0006] In some embodiments, the clamping mechanism includes a support frame mounted on a workbench, a support block slidably mounted on the support frame, a second cylinder mounted on the support frame and used to drive the support block to slide laterally back and forth, and a third cylinder mounted on the support block. The piston rod of the third cylinder is connected to a pressure plate, and the third cylinder drives the pressure plate to reciprocate longitudinally. One end of the pressure plate has two clamping parts distributed on both sides of the output shaft, and the two clamping parts are used to simultaneously clamp the bearing on the output shaft.

[0007] In some embodiments, the output shaft height detection mechanism includes a support plate mounted on a workbench, a longitudinal sliding plate mounted on the support plate, and a height detection probe mounted on the longitudinal sliding plate. The support plate is provided with a fourth cylinder for driving the longitudinal sliding plate to slide longitudinally back and forth. The fourth cylinder drives the height detection probe to move downward through the longitudinal sliding plate, so that the height detection probe abuts against the upper end of the output shaft to measure the installation height.

[0008] In some embodiments, the carrier includes a carrier base and an elastic clamping mechanism. The top of the carrier base is provided with a receiving groove for accommodating a bearing on an output shaft. The elastic clamping mechanism includes a positioning block fixed to the carrier base, a positioning clamp plate slidably disposed on the carrier base, and a spring connected between the positioning clamp plate and the positioning block. The spring provides a radial elastic preload force to move the positioning clamp plate toward the receiving groove and apply a radial elastic preload force to the bearing, thereby pressing the bearing into the receiving groove.

[0009] In some embodiments, the carrier seat is provided with a sliding hole communicating with the receiving groove, the positioning clamp is slidably disposed in the sliding hole, one end of the spring abuts against the positioning groove of the positioning block, and the other end of the spring abuts against the positioning part at one end of the positioning clamp.

[0010] In some embodiments, the other end of the positioning clamp has an arc-shaped groove that matches the outer peripheral wall of the bearing.

[0011] In some embodiments, the positioning clamp has guide slopes on both sides that are transitionally connected to the arc-shaped pressure groove.

[0012] In some embodiments, the output shaft height detection mechanism and the output shaft torque detection mechanism are arranged sequentially along the rotation direction of the turntable to form a continuous detection station.

[0013] In some embodiments, the inner wall of the sleeve groove is provided with an anti-slip structure to enhance the transmission connection with the upper end of the output shaft.

[0014] The beneficial effects of this utility model are as follows: Through the cooperation of the turntable and multiple carriers, continuous rotation and automatic positioning of the output shaft are achieved. Height detection and torque detection are integrated into the same device, significantly improving detection efficiency and reducing manual intervention and workpiece handling time. The use of a servo motor drive in conjunction with a torque sensor enables precise control of the rotational speed and real-time acquisition of torque data. The snap-fit ​​design between the sleeve and the upper end of the output shaft, combined with the axial clamping of the bearing by the clamping mechanism, effectively simulates the actual working state of the output shaft, ensuring the authenticity and reliability of the torque detection results.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-5As shown, an automated testing device for the output shaft of a reduction gearbox includes a worktable 1, a turntable 2, multiple carriers 3, an output shaft height detection mechanism 4, and an output shaft torque detection mechanism 5. The turntable 2 is rotatably mounted on the worktable 1 and driven by a stepper motor. The multiple carriers 3 are distributed circumferentially along the turntable and are used to transport the output shaft 6 of the reduction gearbox to be tested. The output shaft height detection mechanism 4 is mounted on the worktable 1 and is used to detect the installation height of the output shaft 6 of the reduction gearbox on the carrier. The output shaft torque detection mechanism 5 is mounted on the worktable 1 and is used to detect the rotational torque of the output shaft 6 of the reduction gearbox. The output shaft torque detection mechanism 5 includes components mounted on the worktable 1. The support plate 51, the slide plate 52 which can be slidably mounted on the support plate 51, the servo motor 53 mounted on the slide plate 52, the torque sensor 54 mounted on the output end of the servo motor 53, the sleeve 55 connected to the lower end of the torque sensor 54, and the clamping mechanism 56 mounted on the worktable 1 on one side of the sleeve 55, the support plate 51 is provided with a first cylinder 57 for driving the slide plate 52 to slide longitudinally back and forth, the bottom of the sleeve 55 is provided with a groove 551 that cooperates with the upper end of the output shaft 6, and the clamping mechanism 56 is used to apply an axial clamping force to the bearing 61 on the output shaft 6 during torque detection so that the bearing 61 is pressed against the carrier 3. The clamping mechanism 56 includes a support frame 561 mounted on the worktable 1, a support block 562 slidably mounted on the support frame 561, a second cylinder 563 mounted on the support frame 561 and used to drive the support block 562 to reciprocate laterally, and a third cylinder 564 mounted on the support block 562. A pressure plate 565 is connected to the piston rod end of the third cylinder 564. The third cylinder 564 drives the pressure plate 565 to reciprocate longitudinally. One end of the pressure plate 565 has two clamping parts 5651 distributed on both sides of the output shaft 6. The two clamping parts 5651 are used to simultaneously clamp the bearing 61 on the output shaft 6. The clamping mechanism achieves rapid and precise positioning and clamping of the bearing on the output shaft by driving the support block to move laterally with the second cylinder and driving the pressure plate to clamp longitudinally with the third cylinder. The two clamping parts are symmetrically distributed, enabling uniform force application and preventing the bearing from tilting due to unilateral force, further improving the stability and accuracy of torque detection. The output shaft height detection mechanism 4 includes a support plate 41 mounted on the worktable 1, a longitudinally slidable slide plate 42 mounted on the support plate 41, and a height detection probe 43 mounted on the slide plate 42. A fourth cylinder 44 is mounted on the support plate 41 to drive the slide plate 42 to slide longitudinally back and forth. The fourth cylinder 44 drives the height detection probe 43 downwards via the slide plate 42, causing the height detection probe 43 to contact the upper end of the output shaft 6 for installation height measurement. By driving the slide plate and height detection probe downwards via the fourth cylinder, ensuring stable contact with the upper end of the output shaft, automated and rapid measurement of the installation height is achieved. This structure offers rapid response and high repeatability, effectively ensuring the efficiency and consistency of height detection.

[0021] like Figure 3-5 As shown, the carrier 3 includes a carrier base 31 and an elastic clamping mechanism 32. The top of the carrier base 31 is provided with a receiving groove 300 for accommodating the bearing 61 on the output shaft 6. The elastic clamping mechanism 32 includes a positioning block 321 fixed on the carrier base 31, a positioning clamping plate 322 slidably disposed on the carrier base 31, and a spring 323 connecting the positioning clamping plate 322 and the positioning block 321. The spring 323 provides a radial elastic preload force to move the positioning clamping plate 322 toward the receiving groove 300 and to press the bearing 61 into the receiving groove 300. By using the elastic clamping mechanism and providing a continuous radial preload force through the spring, the bearing is kept stably and tightly against the receiving groove during the inspection process, preventing displacement or loosening of the workpiece during the transfer and inspection process. This provides a stable reference positioning for both inspections and improves the reliability of the inspection results. The carrier base 31 is provided with a sliding hole 311 communicating with the receiving groove 300. The positioning clamp 322 is slidably disposed in the sliding hole 311. One end of the spring 323 abuts against the positioning groove of the positioning block 321, and the other end of the spring 323 abuts against the positioning part 3221 at one end of the positioning clamp 322. The other end of the positioning clamp 322 has an arc-shaped pressure groove 3222 that matches the outer peripheral wall of the bearing 61. The positioning clamp is guided by the sliding hole, the spring is evenly stressed, and the movement is smooth. The arc-shaped pressure groove matches the outer wall of the bearing, increasing the contact area and providing reliable clamping force while avoiding damage to the bearing caused by excessive local stress. The positioning clamp 322 has guide slopes 3223 on both sides that transition to the arc-shaped pressure grooves 3222. The design of the guide slopes facilitates the smooth entry of the bearing into the receiving groove and guides the positioning clamp to open and return, improving loading efficiency and operational smoothness.

[0022] like Figure 1 As shown, the output shaft height detection mechanism 4 and the output shaft torque detection mechanism 5 are arranged sequentially along the rotation direction of the turntable 2, forming a continuous detection station. Arranging the height and torque detection stations sequentially along the rotation direction of the turntable creates a continuous detection process, enabling seamless transfer and synchronous detection of the workpiece between the two stations, further optimizing the cycle time and improving overall detection efficiency.

[0023] like Figure 2 As shown, the inner wall of the slot 551 of the sleeve 55 is provided with an anti-slip structure to enhance the transmission connection with the upper end of the output shaft 6. The anti-slip structure (such as patterns, knurling, etc.) on the inner wall of the slot of the sleeve increases the friction with the upper end of the output shaft, effectively preventing slippage during torque testing and ensuring the authenticity of torque transmission and the accuracy of test data.

[0024] By cooperating with a turntable and multiple carriers, continuous rotation and automatic positioning of the output shaft are achieved. Height and torque detection are integrated into a single device, significantly improving detection efficiency and reducing manual intervention and workpiece handling time. A servo motor drive combined with a torque sensor enables precise speed control and real-time torque data acquisition. The snap-fit ​​design between the sleeve and the upper end of the output shaft, combined with the axial clamping of the bearing by the clamping mechanism, effectively simulates the actual working state of the output shaft, ensuring the authenticity and reliability of the torque detection results.

[0025] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
