Description

Technical Field

[0001] This utility model relates to the technical field of quality inspection equipment, specifically to a quality inspection device for hydraulic cylinder piston rods. Background Technology

[0002] The piston rod is one of the main components of a hydraulic telescopic drive assembly and also the main power output component. The extension and retraction of the piston rod can drive the connection to move together, thereby achieving the effects of lifting, pressing or squeezing. It is one of the common power sources in modern industrial production.

[0003] Due to the composition characteristics of hydraulic telescopic components, the requirements for piston rods are very high, and production requires multiple inspections. This also leads to each inspection device being relatively simple, which easily results in problems during the final inspection stage, causing the piston rods to be returned for reprocessing and wasting time. Therefore, this paper proposes a quality inspection device for hydraulic cylinder piston rods. Utility Model Content

[0004] The technical problem this invention aims to solve is that, due to the compositional characteristics of hydraulic telescopic components, the requirements for piston rods are very high, and production requires multiple inspections. This results in each inspection device being relatively simple, which easily leads to problems in the final inspection stage, causing the piston rod to be returned for reprocessing, wasting time. The invention provides a hydraulic cylinder piston rod quality inspection device that integrates multiple common and key indicators into one inspection component. This allows for multi-faceted inspection, timely detection of problems for rework, and time savings.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a hydraulic cylinder piston rod quality detection device, including a fixed platform, a groove is opened in the middle of the top side wall of the fixed platform, a slider is slidably connected in the groove, and a positioning seat is detachably connected to the top side wall of the slider. A follower plate is slidably connected to the top of the positioning seat and near both ends. A lifting plate is telescopically connected in the follower plate. A movable plate is provided on one side of the positioning seat. An infrared rangefinder is connected to one side of the movable plate. A camera is connected to the side of the positioning seat away from the movable plate.

[0006] As a preferred technical solution of this utility model, the side wall opposite to the positioning seat of the movable plate is detachably connected to a guide rail, three moving blocks are slidably connected on the guide rail, and an infrared rangefinder is detachably connected to one side wall of the moving block.

[0007] As a preferred technical solution of this utility model, the fixed platform is detachably connected to a base on the side wall below the movable plate, and a telescopic rod is detachably connected inside the base. The output end of the telescopic rod is detachably connected to the bottom side wall of the movable plate. The structural composition between the lifting plate and the following plate is the same as that of the movable plate and the base.

[0008] As a preferred technical solution of this utility model, a bracket is fixedly connected to the top side wall of the fixed platform, a notch is opened at the top of the bracket, and a driver is detachably connected to one side of the notch. The camera is detachably connected to the output end of the driver.

[0009] As a preferred embodiment of this utility model, a movable groove is provided in the middle of the top side wall of the positioning seat, and a bidirectional screw is rotatably connected in the movable groove. An adjustment motor is detachably connected to the outer wall of one end of the positioning seat, and the output end of the adjustment motor extends into the movable groove and is detachably connected to one end of the bidirectional screw.

[0010] As a preferred technical solution of this utility model, a rotating motor is detachably connected to one side wall of the lifting plate, and a clamping plate is rotatably connected to the side of the follower plate away from the lifting plate. The output end of the rotating motor passes through the follower plate and is detachably connected to one side of the clamping plate. An anti-slip pad is fixed to the side wall of the clamping plate away from the lifting plate.

[0011] This invention has the following advantages: The piston rod to be tested is placed between two lifting plates. The piston rod is clamped and positioned by the mutual approach of the two follower plates via a clamping plate. Then, a rotating motor is started to drive the clamping plate to rotate the piston rod. The positioning seat moves through the slide groove and the slider inside, thereby moving the piston rod. During the rotation and movement of the piston rod, the horizontality of the piston rod can be detected by an infrared rangefinder to prevent the piston rod from bending. Similarly, a camera can perform visual inspection of the piston rod to detect whether the surface of the piston rod is smooth and flat. This facilitates timely detection of problems and rework, saving time. Attached Figure Description

[0016] Please refer to the following: Figure 1-3 This utility model discloses a hydraulic cylinder piston rod quality detection device, including a fixed platform 1. A slide groove 2 is provided in the middle of the top side wall of the fixed platform 1. A slider is slidably connected in the slide groove 2. A positioning seat 3 is detachably connected to the top side wall of the slider. A follower plate 6 is slidably connected to the top and near both ends of the positioning seat 3. A lifting plate 11 is telescopically connected in the follower plate 6. A movable plate 14 is provided on one side of the positioning seat 3. An infrared rangefinder 17 is connected to one side of the movable plate 14. A camera 10 is connected to the side of the positioning seat 3 away from the movable plate 14.

[0017] The side wall opposite to the positioning seat 3 of the movable plate 14 is detachably connected to the guide rail 15. Three moving blocks 16 are slidably connected on the guide rail 15. An infrared rangefinder 17 is detachably connected to one side wall of the moving block 16. The side wall of the fixed platform 1 located below the movable plate 14 is detachably connected to the base 13. A telescopic rod 18 is detachably connected inside the base 13. The output end of the telescopic rod 18 is detachably connected to the bottom side wall of the movable plate 14. The structure between the lifting plate 11 and the follower plate 6 is the same as that of the movable plate 14 and the base 13. A bracket 9 is fixedly connected to the top side wall of the fixed platform 1. A notch is opened at the top of the bracket 9, and a driver 19 is detachably connected to one side of the notch. The camera 10 is detachably connected to the output end of the driver 19.

[0018] The technical effect of this solution is as follows: The piston rod to be tested is placed between two lifting plates 11. Then, the adjusting motor 4 is started to drive the bidirectional screw 8 to rotate. The rotation of the bidirectional screw 8 controls the movement of the follower plate 6 through the thread relationship, thereby driving the lifting plate 11 to move synchronously and clamp and position the piston rod. Then, the position and spacing of the three infrared rangefinders 17 are adjusted according to the length of the piston rod, generally corresponding to the two ends and the middle of the piston rod. By detecting the distance between these three points and the infrared rangefinders 17, it can be determined whether the piston rod is straight. Similarly, since the position of the clamping plate 12 is fixed, the diameter of the piston rod can also be detected by knowing the distance between the infrared rangefinders 17 and the piston rod.

[0019] On the other side of the fixed platform 1, a camera 10 is connected via a bracket 9. The camera 10 performs visual inspection of the piston rod surface to determine whether there are scratches on the piston rod surface. This allows one device to perform two different inspections. If either one fails, the device will be reworked directly. This avoids the problem of a single inspection causing the failure to be judged in a later inspection stage, thus saving rework and transportation time.

[0020] A movable groove 5 is provided in the middle of the top side wall of the positioning seat 3. A bidirectional screw 8 is rotatably connected in the movable groove 5. An adjustment motor 4 is detachably connected to the outer wall of one end of the positioning seat 3. The output end of the adjustment motor 4 extends into the movable groove 5 and is detachably connected to one end of the bidirectional screw 8. A rotary motor 7 is detachably connected to one side wall of the lifting plate 11. A clamping plate 12 is rotatably connected to the side of the follower plate 6 away from the lifting plate 11. The output end of the rotary motor 7 passes through the follower plate 6 and is detachably connected to one side of the clamping plate 12. An anti-slip pad is fixed to the side wall of the clamping plate 12 away from the lifting plate 11.

[0021] The technical effect of this solution is as follows: the starting slider drives the positioning seat 3 to move back and forth along the slide groove 2, which ensures that the piston rod is fully covered by the infrared rangefinder 17 and the camera 10, avoiding any omissions in detection. Because the infrared rangefinder 17 can be adjusted in position, it can flexibly detect different positions of the piston rod, improving the accuracy of detection. In this application, the guide rail 15, the moving block 16, the slide groove 2, and the slider all adopt the principle of the guide rail 15 cylinder. Since this is a mature technology, it will not be described in detail here.

[0022] Specifically, when using this utility model, the piston rod is clamped and positioned by the lifting plate 11. Then, the rotating motor 7 is started to drive the piston rod to rotate via the clamping plate 12. Then, the slider is started to drive the positioning seat 3 and the piston rod to move. During the movement, the rotating piston rod is detected by the infrared rangefinder 17 and the camera 10. The infrared rangefinder 17 detects the distance of the piston rod at different positions. If the distance between the three points is different, the piston rod is not flat. Otherwise, it is flat. The camera 10 can detect scratches on the surface of the piston rod.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
