Description

Technical Field

[0001] This utility model relates to the field of steering gear component testing technology, specifically to an input shaft valve port testing device. Background Technology

[0002] As a key component of the transmission system, the valve port structure parameters of the automotive steering gear input shaft directly affect the vehicle's steering performance. Specifically, the valve port width is positively correlated with the adjusting torque, while the valve port angle determines the leakage characteristics of the left and right chambers during valve adjustment. These two parameters also directly relate to the assembly precision level of the entire assembly. Currently, the commonly used inspection methods in the industry have significant drawbacks: traditional visual comparison relies on human judgment, with measurement errors exceeding ±0.2mm, resulting in a high product defect rate; while the profilometer measurement method offers higher precision, it requires sending the workpiece to a metrology room for operation by professionals, necessitating production interruption while waiting for inspection results. This is particularly problematic during model changeovers and first / last piece inspections, where each inspection cycle averages 2-3 hours, severely impacting production line efficiency. These two inspection methods not only increase labor costs (requiring dedicated inspection personnel) but also result in a daily capacity loss of approximately 30% due to low inspection efficiency. Therefore, developing an automated system capable of rapidly and accurately inspecting multiple product models on-site has become a key technological requirement for improving the production quality and efficiency of steering gears. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes an input shaft valve port detection device. It takes pictures with an industrial camera and displays the data intuitively on a screen, allowing operators to directly judge the pass / fail status, reducing the number of inspection steps and significantly improving production changeover efficiency.

[0004] The technical solution adopted by this utility model is as follows: An input shaft valve port detection device includes a base, a first clamping assembly, and a second clamping assembly. The first clamping assembly includes a first bracket, a piston drive, and a first clamp. The first bracket is mounted on one side of the base, and the piston drive is mounted on the first bracket. The output end of the piston drive is connected to the first clamp. The second clamping assembly includes a second bracket, a rotary motor, and a second clamp. The second bracket is mounted on the other side of the base, and the rotary motor is mounted on the second bracket. The output end of the rotary motor passes through the base and is connected to the second clamp. The first clamp and the second clamp are coaxially corresponding. The base is provided with a display screen, a controller, and a camera for aligning the input shaft valve port. The camera and the display screen are respectively connected to the controller.

[0005] Optionally, the end of the first clamp facing the second clamp has a tapered structure, the second clamp has a groove for mounting the input shaft, and the end of the second clamp facing the first clamp has a protrusion for engaging with the slot on the input shaft.

[0006] Optionally, the base is provided with a light-emitting element, which is located between the camera and the second clamp, and the light emitted by the light-emitting element is directed toward the second clamp.

After the camera takes a picture, it sends the data to the controller. The controller displays the analyzed data on the display screen. Then the rotary motor continues to drive the second clamp to rotate, so that the other valve port on the input shaft is aligned with the camera. The camera is an industrial camera.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, this embodiment discloses an input shaft valve port detection device, including a base 1, a first clamping assembly, and a second clamping assembly. The first clamping assembly includes a first bracket 2, a piston drive 3, and a first clamp 4. The first bracket 2 is mounted on one side of the base 1, and the piston drive 3 is mounted on the first bracket 2. The output end of the piston drive 3 is connected to the first clamp 4. The second clamping assembly includes a second bracket 5, a rotary motor 6, and a second clamp 7. The second bracket 5 is mounted on the other side of the base 1, and the rotary motor 6 is mounted on the second bracket 5. The output end of the rotary motor 6 passes through the base 1 and is connected to the second clamp 7. The first clamp 4 and the second clamp 7 are coaxially corresponding. The base 1 is provided with a display screen 13, a controller, and a camera 11 for aligning the valve port of the input shaft 8. The camera 11 and the display screen 13 are respectively connected to the controller. In use, the input shaft 8 is mounted on the second clamp 7. The piston drive 3 drives the first clamp 4 to approach and abut against the input shaft 8. The rotary motor 6 drives the second clamp 7 to rotate, so that one valve port on the input shaft 8 is aligned with the camera 11. After the camera 11 takes a picture, it sends the data to the controller. The controller displays the analyzed data on the display screen 13. Then, the rotary motor 6 continues to drive the second clamp 7 to rotate, so that the other valve port on the input shaft 8 is aligned with the camera 11. The camera 11 is an industrial camera. By taking pictures with the industrial camera, the data is displayed intuitively on the display screen 13. Operators can directly judge the pass / fail status, reduce the inspection process, and significantly improve changeover efficiency and production cycle time.

[0018] like Figure 2 As shown, the end of the first clamp 4 facing the second clamp 7 is a tapered structure 41. The second clamp 7 has a groove 71 for mounting the input shaft 8, and the end of the second clamp 7 facing the first clamp 4 has a locking protrusion 72 for engaging with the slot on the input shaft 8. The tapered structure 41 enables rapid centering and stable clamping of the input shaft 8; the engagement between the slot and the locking protrusion 72 on the input shaft 8 prevents circumferential slippage during rotation, ensuring accurate valve port positioning and avoiding detection errors.

[0019] like Figure 1As shown, a light-emitting element 12 is provided on the base 1, positioned between the camera 11 and the second clamp 7. The light emitted by the light-emitting element 12 is directed towards the second clamp 7. The light-emitting element 12 directly illuminates the valve port area, enhancing the reflective effect of the tiny valve port edge, improving image contrast and clarity, and ensuring that the camera 11 captures high-precision images to improve detection reliability. The light-emitting element 12 is a ring with multiple LEDs arranged circumferentially, and a first through-hole corresponding to the lens of the camera 11 is provided in the center of the ring. The ring-shaped distribution of LEDs provides uniform shadowless illumination, eliminating blind spots in detection; the central through-hole avoids obstructing the field of view of the camera 11, ensuring that the light covers the valve port without affecting image quality.

[0020] like Figure 1 As shown, the first support 2 includes a first support plate 21, a first horizontal plate 22, and a second support plate 23. Both ends of the first horizontal plate 22 are connected to the first support plate 21 and the second support plate 23, respectively. The first support plate 21 and the second support plate 23 are connected to the base 1. The piston drive 3 is mounted on the first horizontal plate 22, and its output end passes through the first horizontal plate 22 and connects to the first clamp 4. The piston drive 3 can be a pneumatic cylinder or a hydraulic cylinder. The output end of the piston drive 3 is coaxially connected to a connecting rod 31 via a coupling 32, and the connecting rod 31 is fixedly connected to the first clamp 4. The coupling 32 is existing technology, used to compensate for installation coaxiality deviations and avoid mechanical stress caused by the rigid connection between the piston drive 3 and the clamp. A second horizontal plate 24 is provided between the first support plate 21 and the second support plate 23, located below the first horizontal plate 22. The second horizontal plate 24 has a second through hole through which the connecting rod 31 can move. The second horizontal plate 24 forms a double support structure, which restricts the lateral displacement of the connecting rod 31 and ensures the linear motion trajectory of the clamp.

[0021] In this embodiment, the lamp bead is an adjustable brightness LED light source, and the outer edge of the lamp ring is provided with an arc-shaped reflector for focusing the light. Adjustable brightness LEDs are existing technology, adapting to the reflection characteristics of different materials of the input shaft 8 and optimizing the lighting conditions; the arc-shaped reflector concentrates the light in the valve port area, reducing light energy loss and enhancing local illumination intensity, further improving detection sensitivity.
