Description

Technical Field

[0001] This invention relates to the field of roundness detection device technology, specifically a batch detection device for valve sleeve roundness. Background Technology

[0002] The valve sleeve of a hydraulic cartridge valve is one of the core components, its main function being to fix the valve core and provide precision guidance. The valve sleeve has a cylindrical structure, and its outer surface needs to be inspected for roundness after machining to ensure the accuracy of its fit with the valve body mounting holes. Currently, the main problems in valve sleeve roundness inspection are as follows: 1. In the existing technology, a roundness tester is usually used to inspect valve sleeves one by one. Each valve sleeve needs to be clamped and measured separately, which is inefficient and difficult to meet the inspection requirements of mass production. 2. In actual use, the valve sleeve is in the high-temperature working environment of the hydraulic system. Temperature changes will cause the valve sleeve to thermally expand and deform. However, the existing testing methods are usually carried out at room temperature, which cannot simulate the roundness change of the valve sleeve under high temperature conditions, making it difficult to accurately evaluate its actual performance. 3. After the valve sleeve is processed, there are residual cutting fluid, metal shavings and other impurities on its surface. It usually needs to be cleaned separately by ultrasonic cleaning equipment before testing. The separation of cleaning and testing processes and the turnover of workpieces between different equipment increase the intensity of manual operation and total working time, and increase the risk of bump damage. The cleaned surface may also be contaminated with dust again, affecting the accuracy of testing. 4. Traditional testing clamping methods often use a three-jaw chuck to radially clamp one end of the valve sleeve. If the clamping force is not properly controlled, it can easily cause local deformation at the port of the thin-walled valve sleeve, affecting the accuracy of the test results. To address the aforementioned issues, it is necessary to provide a valve sleeve outer roundness detection device that integrates cleaning, heating, batch testing, and automatic sorting. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a batch valve sleeve roundness inspection device that integrates valve sleeve cleaning, heating, roundness inspection, and automatic sorting into one unit. This solves the problems of low efficiency in valve sleeve roundness inspection, inability to simulate high-temperature working conditions, dispersed processes, and easy deformation during clamping.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a valve sleeve roundness batch inspection device, comprising a platform, and further comprising: The tank is fixedly installed on the platform. It contains multiple conveyor belts for conveying valve sleeves. The tank contains cleaning fluid that can submerge the valve sleeves on the conveyor belts.

An electric telescopic rod for adjusting the height of the lifting beam is fixedly mounted on the gantry frame. Multiple pairs of clamping heads are mounted on the lifting beam, each corresponding to a multiple conveyor belt. The distance between each pair of clamping heads is adjustable.

Each detection head corresponds to one pair of clamping heads. A mounting frame is fixedly mounted on the platform. The transverse platform is slidably mounted on the mounting frame. An electric telescopic rod for adjusting the position of the transverse platform is fixedly mounted on the mounting frame. A discharge hopper is fixedly installed on the platform. The discharge hopper is equipped with a discharge pipe and a storage tank. The valve sleeves that are grabbed can be put into the discharge pipe or the storage tank by moving the gantry frame.

[0005] Preferably, the upper outer side of the clamping head is slidably connected to the side wall of the lifting beam via a slide rail. Multiple cylinders are fixedly installed on the lifting beam corresponding to multiple pairs of clamping heads. The cylinders are located at the center between a pair of clamping heads. A pair of connecting rods are hinged to the top of a pair of clamping heads. The upper ends of the pair of connecting rods are hinged together to the telescopic end of the cylinder.

[0006] Preferably, a spline sleeve is rotatably disposed on the inner side above the clamping head, and a drive shaft is rotatably disposed inside the clamping head. The upper and lower ends of the drive shaft are connected to the spline sleeve and the conical clamping plate through bevel gears. A spline shaft that cooperates with the spline sleeve is rotatably disposed on the lifting beam, and a motor that drives the spline shaft to rotate is fixedly disposed at one end of the lifting beam.

[0007] Preferably, the conveyor belt is a chain plate type, and each chain plate is provided with a groove that matches the shape of the valve sleeve. Two rotating shafts are rotatably arranged in the trough, and multiple pairs of sprockets are fixedly arranged on the two rotating shafts. Multiple conveyor belts are fitted on the multiple pairs of sprockets. A second motor for driving the rotating shafts to rotate is fixedly arranged on the outside of the trough.

[0008] Preferably, a pair of side baffles are fixedly provided on both sides of each conveyor belt conveyor section within the groove, and the spacing between the pair of side baffles matches the length of the valve sleeve.

[0009] Preferably, multiple feeding hoppers are fixedly arranged above the first end of the trough corresponding to the conveying directions of multiple conveyor belts. Only one valve sleeve can pass through the discharge port of the feeding hopper at a time. The distance between the lower end face of the discharge port of the feeding hopper and the lowest point of the groove matches the diameter of the valve sleeve.

[0010] Preferably, a cleaning fluid filter is provided below the platform, a water distribution manifold is fixedly installed at the bottom of the inner wall of the tank near the end of the conveyor belt in the conveying direction, and a water collection manifold is fixedly installed at the bottom of the inner wall of the tank near the beginning of the conveyor belt in the conveying direction. Both the water distribution manifold and the water collection manifold have multiple water distribution holes. The water outlet of the cleaning fluid filter is connected to the water distribution manifold through a pipe, and the water inlet of the cleaning fluid filter is connected to the water collection manifold through a pipe.

[0011] Preferably, a pair of threaded rods are rotatably mounted on the platform, and a threaded sleeve screwed onto the outside of the pair of threaded rods is fixedly mounted at the bottom of the gantry frame. A dual-head motor is fixedly mounted on the platform, and a drive shaft is fixedly connected to each of the two drive ends of the dual-head motor. The end of the drive shaft is connected to the end of the pair of threaded rods by bevel gear transmission.

[0012] Preferably, a receiving groove is fixedly provided on the platform, the groove body is placed in the receiving groove, and a rubber layer is provided between the bottom of the groove body and the receiving groove.

[0013] This invention provides a batch inspection device for valve sleeve roundness, which has the following beneficial effects: 1. By simultaneously moving multiple pairs of gripping heads through the gantry frame and lifting beam, multiple valve sleeves can be grabbed, inspected, and sorted at the same time, resulting in high inspection efficiency and meeting the inspection needs of mass production. By moving the inspection head through the transverse table, the roundness of multiple cross sections along the length of the valve sleeve can be inspected, resulting in more comprehensive inspection results. Through the discharge pipe and storage tank set in the discharge hopper, combined with the feedback of the inspection results from the external controller, the automatic classification of qualified and unqualified products is realized. 2. By installing multiple conveyor belts within the tank and placing ultrasonic transducers below the conveyor belt sections, along with the cleaning fluid within the tank, the valve sleeve is cleaned during the conveying process. This integrates valve sleeve cleaning and inspection into a single process, eliminating the need for a separate cleaning step, reducing workpiece turnaround time and labor intensity, and avoiding the risk of secondary contamination after cleaning. The installation of water distribution and collection manifolds ensures that the cleaning fluid flows in the opposite direction to the valve sleeve's conveying direction within the tank, guaranteeing that the valve sleeve comes into contact with the cleanest cleaning fluid before leaving the cleaning zone, preventing impurities from depositing on the valve sleeve surface. The cleaning fluid is also recycled using a cleaning fluid filter, reducing operating costs. 3. By installing heating rods in the tank, the temperature of the cleaning solution can be increased to enhance the cleaning effect. On the other hand, the cleaning solution can be heated to simulate the actual working temperature of the valve sleeve, so that the valve sleeve reaches the corresponding temperature before testing. This enables the detection of the roundness change of the valve sleeve when it is in a high-temperature working environment. The synergistic effect of cleaning and heating improves the consistency between the test results and the actual operating conditions. 4. The valve sleeve is axially clamped from both ends by the clamping head, so that the outer circular surface of the valve sleeve is fully exposed, which facilitates the detection head to inspect the outer circle. After one clamping, the valve sleeve can be inspected for multiple axial sections at both ends and the middle without secondary clamping. This simplifies the inspection process, improves inspection efficiency, and avoids the drawback of traditional radial clamping that can easily cause deformation to thin-walled valve sleeves, thus ensuring the accuracy of the inspection results.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] Please see Figures 1-8 The present invention provides a technical solution: a valve sleeve roundness batch inspection device, including a platform 1, and further including: Tank 2 is fixedly installed on platform 1. It contains multiple conveyor belts 3 for conveying valve sleeves. Tank 2 contains cleaning fluid that can submerge the valve sleeves on the conveyor belts 3. Multiple ultrasonic transducers 4 are installed below the conveying section of each conveyor belt 3 in tank 2. The cleaning fluid, together with the ultrasonic transducers 4, can clean the valve sleeves on the conveyor belts 3. Heating rods 5 are also installed in tank 2. The heating rods 5 can increase the temperature of the cleaning fluid to improve the cleaning effect. On the other hand, heating the cleaning fluid can raise the temperature of the valve sleeves, so as to detect the shape changes of the valve sleeves when they are in a high-temperature working environment. A gantry frame 6 is slidably mounted on platform 1 via a slide rail. A lifting beam 7 is slidably mounted on one side of the gantry frame 6. An electric telescopic rod 8 for adjusting the height of the lifting beam 7 is fixedly mounted on the gantry frame 6. The lifting beam 7 is equipped with multiple pairs of clamping heads 9 corresponding to multiple conveyor belts 3. The spacing between each pair of clamping heads 9 is adjustable. A conical chuck 10 is rotatably mounted on the inner side below each pair of clamping heads 9. The maximum outer diameter of the conical chuck 10 is larger than the inner diameter of the valve sleeve port, and the minimum outer diameter is smaller than the inner diameter of the valve sleeve port, to ensure that the conical surface forms an annular contact with the inner wall of the valve sleeve port. By moving the gantry frame 6 and raising and lowering the lifting beam 7, [the following can be achieved]. The conical chuck 10 is aligned coaxially with the valve sleeve at the end of the conveyor belt 3 in the moving direction. The valve sleeve can be clamped by bringing the clamping heads 9 close together. Multiple valve sleeves can be gripped simultaneously by multiple pairs of clamping heads 9. The conical chuck 10 clamps and fixes the valve sleeve from both ends. The conical surface of the conical chuck 10 can also automatically center the valve sleeve, while avoiding the disadvantage of the traditional radial clamping method which is prone to deformation of the valve sleeve. The conical chuck 10 clamps the valve sleeve axially from both ends. The outer circular surface of the valve sleeve can be fully exposed after clamping, and multiple sections at both ends and in the middle of the valve sleeve can be detected without secondary clamping. Multiple detection heads 11 are fixedly installed on the transverse stage 12. Each detection head 11 corresponds to a pair of clamping heads 9. The detection heads 11 use contact displacement sensors. By moving the gantry 6 and the lifting beam 7, multiple clamped valve sleeves can be moved and brought to the detection ends of the multiple detection heads 11. The roundness of the valve sleeves can be detected by rotating the conical chuck 10. A mounting frame 13 is fixedly installed on the platform 1. The transverse stage 12 is slidably installed on the mounting frame 13. An electric telescopic rod 14 for adjusting the position of the transverse stage 12 is fixedly installed on the mounting frame 13. By moving the transverse stage 12, the detection ends of the detection heads 11 can be aligned with different positions along the length of the valve sleeve. The discharge hopper 15 is fixedly installed on the platform 1. The discharge hopper 15 is equipped with a discharge pipe 16 and a storage tank 17. The valve sleeves can be picked up and put into the discharge pipe 16 or the storage tank 17 by moving the gantry frame 6. After the inspection is completed, the valve sleeves are moved to the top of the discharge pipe 16 by the gantry frame 6 and the qualified valve sleeves are released and discharged through the discharge pipe 16. The valve sleeves that are found to be defective are moved into the storage tank 17 and released, thus realizing the classification of valve sleeves.

[0018] Furthermore, the outer side of the clamping head 9 is slidably connected to the side wall of the lifting beam 7 via a slide rail. Multiple cylinders 18 are fixedly installed on the lifting beam 7 corresponding to multiple pairs of clamping heads 9. The cylinders 18 are located at the center between a pair of clamping heads 9. A pair of connecting rods 19 are hinged to the top of a pair of clamping heads 9. The upper ends of the pair of connecting rods 19 are hinged to the telescopic end of the cylinder 18. When the cylinder 18 is started, the pair of connecting rods 19 drive the pair of clamping heads 9 to move closer or further away from each other around the cylinder 18, thereby achieving clamping and releasing of the valve sleeve.

[0019] Furthermore, a spline sleeve 20 is rotatably mounted on the inner side of the upper part of the clamping head 9, and a drive shaft 21 is rotatably mounted inside the clamping head 9. The upper and lower ends of the drive shaft 21 are connected to the spline sleeve 20 and the conical chuck 10 through bevel gears. A spline shaft 22 that mates with the spline sleeve 20 is rotatably mounted on the lifting beam 7. The movement of the clamping head 9 and the transmission of torque are satisfied through the mating of the spline sleeve 20 and the spline shaft 22. A motor 23 that drives the spline shaft 22 to rotate is fixedly mounted at one end of the lifting beam 7. After starting the motor 23, multiple pairs of spline sleeves 20 inside the clamping heads 9 can rotate simultaneously. When the spline sleeve 20 rotates, it drives the drive shaft 21 to rotate. The lower end of the drive shaft 21 transmits power to the rotation shaft of the conical chuck 10 through a bevel gear pair, thereby realizing the rotation of the conical chuck 10 and ultimately the rotation of the valve sleeve.

[0020] Furthermore, the conveyor belt 3 adopts a chain plate type, and each chain plate 24 is provided with a groove 25 that matches the shape of the valve sleeve. Two rotating shafts 26 are rotatably arranged inside the trough 2, and multiple pairs of sprockets 27 are fixedly arranged on the two rotating shafts 26. Multiple conveyor belts 3 are fitted on the multiple pairs of sprockets 27. A second motor 28 for driving the rotating shafts 26 to rotate is fixedly arranged on the outside of the trough 2. After starting the second motor 28, multiple conveyor belts 3 can rotate simultaneously to realize the conveying of the valve sleeve. The conveyor belt 3 adopts a stepping movement method, and the stepping distance of the conveyor belt 3 is equal to the length of one chain plate 24.

[0021] Furthermore, a pair of side baffles 29 are fixedly installed on both sides of each conveyor belt 3 conveying section within the groove 25. The spacing between the pair of side baffles 29 matches the length of the valve sleeve. The pair of side baffles 29 prevent the valve sleeve from moving axially within the groove 25 during conveying of the conveyor belt 3. A clamping area is provided at the end of the conveyor belt 3 in the direction of movement. The pair of side baffles 29 do not extend to the clamping area.

[0022] Furthermore, multiple feeding hoppers 30 are fixedly installed above the first end of the conveyor belts 3 in the conveying direction of the trough 2. Only one valve sleeve can pass through the discharge port of the feeding hopper 30 at a time. When the conveyor belt 3 moves, the groove 25 can be vertically aligned with the discharge port to receive the valve sleeve discharged from the discharge port. The distance between the lower end face of the discharge port of the feeding hopper 30 and the lowest point of the groove 25 matches the diameter of the valve sleeve. Multiple valve sleeves can be stored through the feeding hopper 30. When the valve sleeve located at the discharge port enters the groove 25, the next valve sleeve can fall to the discharge port by its own weight, ready to enter the next groove 25, realizing automatic feeding of valve sleeves.

[0023] Furthermore, a cleaning fluid filter 31 is installed below platform 1. A water distribution manifold 32 is fixedly installed at the bottom of the inner wall of tank 2 near the end of the conveyor belt 3 in the conveying direction, and a water collection manifold 33 is fixedly installed at the bottom of the inner wall of tank 2 near the beginning of the conveyor belt 3 in the conveying direction. Multiple water distribution holes are opened on both the water distribution manifold 32 and the water collection manifold 33. The outlet end of the cleaning fluid filter 31 is connected to the water distribution manifold 32 through a pipe 34, and the inlet end of the cleaning fluid filter 31 is connected to the water collection manifold 33 through a pipe 34. A circulation pump is installed in the cleaning fluid filter 31 to filter impurities in the cleaning fluid in real time. The water distribution manifold 32 and the water collection manifold 33 can make the cleaning fluid flow evenly in tank 2, reduce the dead zone of the cleaning fluid flow, and at the same time, the flowing cleaning fluid can make the water temperature more uniform and improve the uniformity of heating of each valve sleeve.

[0024] Furthermore, a pair of threaded rods 35 are rotatably mounted on platform 1, and a threaded sleeve 36 screwed onto the outside of the pair of threaded rods 35 is fixedly mounted on the bottom of the gantry 6. A dual-head motor 37 is fixedly mounted on platform 1, and a drive shaft 38 is fixedly connected to each of the two drive ends of the dual-head motor 37. The end of the drive shaft 38 is connected to the end of the pair of threaded rods 35 by bevel gear transmission. By starting the dual-head motor 37, the two threaded rods 35 can rotate simultaneously, thereby providing driving force to the bottom ends of the gantry 6 at the same time, so that it can move along the slide rail and improve the stability of the movement of the gantry 6.

[0025] Furthermore, a receiving groove is fixedly provided on the platform 1, and the groove body 2 is placed in the receiving groove. A rubber layer 39 is provided between the bottom of the groove body 2 and the receiving groove. The rubber layer 39 can absorb and consume the vibration energy brought by the ultrasonic wave, so as to avoid affecting the detection accuracy of the detection head 11.

[0026] Working principle and usage process of this invention: Material preparation stage: Fill the tank 2 with cleaning fluid. The cleaning fluid should cover the valve sleeve located on the conveyor belt 3. Place the processed valve sleeve into the feeding hopper 30 and ensure that the valve sleeves in each feeding hopper 30 are placed in the same direction. Cleaning and heating stage: Starting motor 28 causes multiple conveyor belts 3 to move simultaneously. The step-by-step movement of the conveyor belts 3 positions a groove 25 at the beginning of each belt directly below the discharge port of the hopper 30. The discharge port of the hopper 30 guides the valve sleeve inside into the groove 25. As the conveyor belts 3 move the valve sleeve, an external ultrasonic generator drives the ultrasonic transducer 4 inside the tank 2 to generate high-frequency vibrations, which are then transmitted to the cleaning fluid, thus cleaning the valve sleeve. The heating rod 5 heats the cleaning fluid, improving the cleaning efficiency. On the other hand, it can heat the valve sleeve and detect the shape change of the valve sleeve when it is in a high-temperature working environment. By activating the cleaning fluid filter 31, the cleaning fluid can be filtered in time. The filtered cleaning fluid enters the tank 2 from the end of the conveyor belt 3 in the conveying direction through the water distribution manifold 32, and is discharged through the water collection manifold 33 set at the beginning of the conveyor belt 3 in the conveying direction. This ensures that the liquid flow direction in the tank 2 is opposite to the valve sleeve movement direction, so that the valve sleeve comes into contact with the cleanest cleaning fluid before leaving the cleaning area and avoids impurities from depositing on the valve sleeve surface. During the inspection phase: When the valve sleeve is moved to the end of the conveyor belt 3, it is in the clamping area. The gantry 6 moves and the lifting beam 7 rises and falls under the control of the external controller, so that the conical clamp 10 is initially aligned with the axis of the valve sleeve in the clamping area. By activating multiple cylinders 18, multiple pairs of clamping heads 9 are driven to move closer to each other, so that the conical clamp 10 is clamped at both ends of the valve sleeve. The conical surface of the conical clamp 10 is inserted into the port of the valve sleeve, realizing automatic centering of the valve sleeve and the conical clamp 10. After clamping, the lifting beam 7 is raised to remove the valve sleeve from the cleaning liquid surface. The motor 23 is started to drive the spline shaft 22 to rotate, and the spline shaft 22 drives the conical clamp 10 in the multiple pairs of clamping heads 9 to rotate simultaneously. The clamped valve sleeve is rotated, and the residual cleaning fluid can be thrown out by centrifugal force through the rotation of the valve sleeve. Then, the valve sleeve is moved above the detection end of the detection head 11 by the gantry 6 and the lifting beam 7, so that the detection end of the detection head 11 abuts against the detection surface of the valve sleeve. The motor 23 is started again to make the valve sleeve rotate, and the roundness of the valve sleeve is detected by the detection head 11. When it is necessary to adjust the axial detection position of the valve sleeve, the lifting beam 7 is raised to make the valve sleeve disengage from the detection end of the detection head 11. The electric telescopic rod 14 is started to move the transverse stage 12, so that the detection head 11 can detect at least two axial sections (such as the two ends and the middle) of the outer circle of the valve sleeve to evaluate the roundness of the entire outer circle. Material feeding stage: Each detection head 11 is connected to an external controller and can feed back its detection results to the external controller. The external controller can control each cylinder 18 to start individually. After the detection is completed, the valve sleeve is moved to the top of the discharge pipe 16 through the gantry 6 and the lifting beam 7. The external controller drives the cylinder 18 according to the detection results to put the valve sleeve with the set value into the discharge pipe 16. That is, the cylinder 18 opens a pair of clamping heads 9 with qualified valve sleeves. Qualified valve sleeves can be discharged through the discharge pipe 16. When a non-qualified valve sleeve is detected, the gantry 6 moves the valve sleeve to the top of the storage tank 17 and opens a pair of clamping heads 9 with non-qualified valve sleeves, thus realizing the distinction between qualified and non-qualified valve sleeves.

[0027] In the specific embodiments of the present invention, the settings of the controller and the control logic of each electric actuator and sensor are conventional technical means that can be set by those skilled in the art according to actual needs, and are not the core improvement of the present invention. Therefore, they will not be described in detail here.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
