Description

Technical Field

[0001] This utility model relates to the field of gear shaft detection technology, specifically to an automated damage detection system for perforated gear shafts. Background Technology

[0002] As a core component of mechanical transmission systems, gear shafts are widely used in automotive gearboxes, industrial robots, aerospace equipment, heavy machinery and other fields. They transmit power and motion through gear meshing and are subjected to high torque, periodic loads and complex working conditions for a long time. They are prone to defects such as wear, cracks, broken teeth and deformation on the tooth surface, tooth root and journal.

[0003] Traditional gear shaft inspection mainly relies on manual visual inspection and contact measuring tools. Operators rely on experience to observe the surface finish and color changes of the gears, or manually measure parameters such as tooth pitch and tooth thickness using measuring tools. However, manual inspection has significant limitations: First, it is highly subjective and easily affected by factors such as fatigue, lighting conditions, and viewing angle limitations, resulting in a high rate of missed detection of defects such as micro-cracks and shallow wear. Second, it is inefficient and cannot meet the rapid quality inspection requirements of modern production lines for large batches of gear shafts. Third, contact measurement may scratch the precision tooth surface, especially for surface-hardened or high-precision gears, posing a risk of secondary damage.

[0004] With the development of machine vision technology, some companies have begun to introduce automated inspection equipment, using industrial cameras to acquire images of the gear shaft surface and combining them with image processing algorithms to identify defects. However, there are many types of gear shafts, including solid shafts, hollow shafts, and irregularly shaped shafts with different diameters and length-to-diameter ratios. Existing fixtures are mostly designed for specific models and lack adaptive adjustment capabilities. Furthermore, to obtain high-definition images of the entire gear shaft surface, it is necessary to precisely control its relative position and rotation angle with the camera. Existing equipment mostly uses manually adjustable slides or simple motor drives, resulting in low positioning accuracy, poor repeatability, and difficulty in ensuring consistent image clarity for each tooth groove and tooth tip, leading to poor inspection results and low efficiency.

[0005] Therefore, in order to address the above issues, the applicant needs to design an automated damage detection system for gear shafts. Utility Model Content

[0006] The purpose of this invention is to provide an automated damage detection system for toothed shafts to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automated damage detection system for toothed shafts, including a base.

[0008] It also includes: a support column set on the base, and an extension arm fixedly set on the support column, an industrial camera rotatably set on the extension arm, and the industrial camera is used to photograph the gear shaft and transmit the high-definition image of the gear shaft to the inspection computer;

[0009] A clamping mechanism for clamping different types of gear shafts, the clamping mechanism includes a servo motor, and the output end of the servo motor is provided with a connecting rod. A fixed plate is slidably provided on the connecting rod, and a connecting member is fixedly provided on one side of the fixed plate. A clamping block is rotatably provided on the connecting member, and a limiting member is rotatably provided on the clamping block. A hollow sleeve is rotatably provided on the limiting member, and the hollow sleeve is fixedly connected to the fixed plate.

[0010] A connecting plate is located below the servo motor, and a control mechanism is located below the connecting plate. The control mechanism is used to drive the clamping mechanism to move.

[0011] Furthermore, a buffer spring is fixedly installed on one side of the fixed plate, and a control nut is fixedly installed on the end of the buffer spring away from the fixed plate, and the control nut is threadedly connected to the connecting rod.

[0012] With the above structural design, when in use, external force is used to rotate the control nut. The movement of the control nut will compress the buffer spring. The movement of the buffer spring will drive the fixed plate to move. The movement of the fixed plate will drive the connecting piece to move. The movement of the connecting piece will drive the clamping block to move. Under the action of the limiting piece, the clamping block can easily change the offset angle, thereby firmly clamping the gear shaft.

[0013] Furthermore, a reset spring is fixedly provided on the clamping block, and a moving block is fixedly provided at the end of the reset spring away from the clamping block.

[0014] With the above structural design, when the gear shaft is a hollow shaft, pressing the moving block will squeeze the return spring, and the return spring will generate elastic force. Then, the gear shaft will be sleeved on the outside of the moving block, and the position of the control nut will be adjusted to make it easier to lock the gear shaft securely.

[0015] Furthermore, the control mechanism includes a slide groove, inside which a slider is slidably arranged, and the slider is fixedly connected to the connecting plate. The slider is threaded with a lead screw, and one end of the lead screw is equipped with a servo motor.

[0016] With the above structural design, when in use, starting the second servo motor will drive the lead screw to rotate. The rotation of the lead screw will drive the slider to move along the slide groove in a specific direction, thereby driving the clamping mechanism to move. This will adjust the position between the gear shaft and the industrial camera, improve the shooting effect, and thus improve the detection effect.

[0017] Furthermore, a stabilizing seat is rotatably provided at the end of the lead screw away from the servo motor 2, and the stabilizing seat is fixedly connected to the slide groove.

[0018] Through the above structural design, the stabilizing seat facilitates the support of the lead screw, thereby improving the stability and smoothness of the lead screw rotation.

[0019] Furthermore, a fixing rod is fixedly provided on the bottom surface of the slide, and the end of the fixing rod away from the slide is fixedly connected to the base.

[0020] The above structural design utilizes a fixed rod to facilitate support of the slide, thereby improving the stability of the slide.

[0021] Furthermore, a light-concentrating cover is fixedly installed on the extension arm, and the light-concentrating cover is adapted to an industrial camera.

[0022] The above structural design utilizes a condenser to improve the shooting effect of industrial cameras, thereby enhancing the detection results.

[0023] Compared with the prior art, the beneficial effects of this utility model are: the automatic damage detection system for toothed shafts uses a clamping mechanism to clamp different types of toothed shafts, and facilitates automatic imaging of the clamped toothed shafts, resulting in high detection efficiency and good results. The specific details are as follows:

[0024] In operation, this automated gear shaft damage detection system uses a clamping mechanism to hold the gear shaft in place, and simultaneously activates an industrial camera. Servo motor two drives a lead screw to rotate, which in turn moves a slider along a groove. This slider movement moves a connecting plate, which in turn moves the clamping mechanism, which in turn moves the gear shaft to adjust its position relative to the industrial camera. Once adjustment is complete, servo motor one is activated, rotating the gear shaft. Meanwhile, the industrial camera continuously captures images of the gear shaft and transmits these images to a detection computer. This system offers high detection efficiency and excellent results.

[0025] When using this automated gear shaft damage detection system, if the gear shaft is solid, external force is used to rotate the control nut. The movement of the control nut compresses the buffer spring, which in turn moves the fixed plate. The fixed plate then moves the connecting piece, which in turn moves the clamping block. Under the action of the limiting component, the clamping block can easily change its offset angle, thus firmly clamping the gear shaft. When the gear shaft is hollow, pressing the moving block compresses the return spring. The return spring generates elastic force, and the gear shaft is then sleeved on the outside of the moving block. Adjusting the position of the control nut will facilitate the secure locking of the gear shaft, thus ensuring the stability of different types of gear shafts. Attached Figure Description

[0033] The control mechanism 3 includes a slide 31, a slider 32 is slidably arranged inside the slide 31, and the slider 32 is fixedly connected to the connecting plate 14. A lead screw 33 is threaded inside the slider 32, and a servo motor 34 is provided at one end of the lead screw 33. A stabilizing seat 35 is rotatably arranged at the end of the lead screw 33 away from the servo motor 34, and the stabilizing seat 35 is fixedly connected to the slide 31. A fixing rod 30 is fixedly arranged on the bottom surface of the slide 31, and the end of the fixing rod 30 away from the slide 31 is fixedly connected to the base 1. A focusing cover 13 is fixedly arranged on the extension arm 11, and the focusing cover 13 is adapted to the industrial camera 12.

[0034] With the above structural design, during use, the clamping mechanism 2 clamps the gear shaft, and the industrial camera 12 is activated. Simultaneously, the second servo motor 34 is activated, which drives the lead screw 33 to rotate. The rotation of the lead screw 33 drives the slider 32 to move directionally along the slide groove 31. The movement of the slider 32 drives the connecting plate 14 to move, which in turn drives the clamping mechanism 2 to move. The clamping mechanism 2 then drives the gear shaft to move, adjusting the position between the gear shaft and the industrial camera 12. After adjustment, the first servo motor 20 is activated, which drives the gear shaft to rotate. At the same time, the industrial camera 12 continuously captures images of the gear shaft and transmits the images to the inspection computer.

The movement of the buffer spring 28 will drive the fixed plate 22 to move. The movement of the fixed plate 22 will drive the connecting piece 23 to move. The movement of the connecting piece 23 will drive the clamping block 24 to move.

When the gear shaft is hollow, pressing the moving block 290 will compress the return spring 29. The return spring 29 will generate elastic force. Then, the gear shaft will be sleeved on the outside of the moving block 290, and the position of the control nut 27 will be adjusted to securely lock the gear shaft, thereby making it easy to keep different types of gear shafts stable.

[0037] Working Principle: When using this automatic damage detection system for the toothed shaft, external force is used to rotate the control nut 27. The movement of the control nut 27 compresses the buffer spring 28, which in turn moves the fixed plate 22. The movement of the fixed plate 22 then moves the connecting piece 23, which in turn moves the clamping block 24. Under the action of the limiting piece 25, the clamping block 24 can easily change its offset angle, thereby firmly clamping the toothed shaft. After the clamping mechanism 2 clamps the toothed shaft, the industrial camera 12 is activated, and the servo motor 24 is also activated. Servo motor 2 34 drives lead screw 33 to rotate. The rotation of lead screw 33 drives slider 32 to move directionally along slide groove 31. The movement of slider 32 drives connecting plate 14 to move. Connecting plate 14 drives clamping mechanism 2 to move. Clamping mechanism 2 drives gear shaft to move, adjusting the position between gear shaft and industrial camera 12. After adjustment, servo motor 1 20 is started. Servo motor 1 20 drives gear shaft to rotate.
