Description

Technical Field

[0002] Hydraulic valves are key components in hydraulic systems. They are mainly used to control and adjust the flow direction, pressure and flow of hydraulic fluid, thereby achieving precise control of actuators.

However, in the process of detecting products, the prior art needs to use a linear motor platform to drive the product placed on the positioning fixture to move to the camera detection module to complete the detection, and then drive the positioning fixture to move the product to the laser detection module for detection. After all the detections are completed, the linear motor platform needs to transport the product back to the loading position for unloading before loading.

The cleaning component 5 includes a cleaning head 53 and a cleaning brush rod 54. The cleaning head 53 is installed on the side of the driving component 4 close to the feeding end 11. The cleaning head 53 is provided with an air jet 532. The cleaning brush rod 54 is connected to the cleaning head 53. The detection module 6 is installed on the other side of the driving component 4. The detection module 6 is provided with a laser probe 61. After the hydraulic valve 8 is positioned, the driving component 4 drives the cleaning head 53 and the laser probe 61 to move down into the inner cavity of the hydraulic valve 8. The cleaning brush rod 54 on the cleaning head 53 rotates to clean the inner cavity of the hydraulic valve 8, and blows off the impurities brushed off through the air jet 532. The laser probe 61 detects the cleaned inner cavity of the hydraulic valve 8 through laser.

[0020] When in use, the device is first started, and the conveyor belts 28 on the fixed frame 21 and the mobile frame 22 are started synchronously, and begin to rotate from the loading end 11 to the unloading end 12. At the loading end 11 of the detection cabinet 1, a plurality of hydraulic valves 8 to be tested are placed one by one on the conveyor belt 28, so that the side of the hydraulic valve 8 is located between the fixed frame 21 and the mobile frame 22, and the bottom sides of the hydraulic valve 8 are placed on the conveyor belts 28 of the fixed frame 21 and the mobile frame 22 respectively, so that the inner cavity of the hydraulic valve 8 is in the gap between the fixed frame 21 and the mobile frame 22. When the first hydraulic valve 8 to be tested moves to the bottom of the cleaning component 5, the positioning component 3 corresponding to the cleaning component 5 fixes the hydraulic valve 8, so that the hydraulic valve 8 cannot move, while other hydraulic valves 8 continue to follow the conveyor belt 28. Move, after the first hydraulic valve 8 is fixed, the driving component 4 drives the cleaning component 5 and the detection module 6 to move downward synchronously, so that the cleaning brush rod 54 under the cleaning head 53 is inserted into the inner cavity of the hydraulic valve 8, and the cleaning brush rod 54 rotates at the same time to clean the inner cavity of the hydraulic valve 8 and brush away the pollutants remaining in the inner cavity of the hydraulic valve 8. When the cleaning head 53 is also inserted into the inner cavity of the hydraulic valve 8 so that the air jet 532 is located at the upper end of the inner cavity of the hydraulic valve 8, the cleaning brush rod 54 completes the cleaning of the inner cavity of the hydraulic valve 8 and stops rotating. At the same time, the air jet 532 ejects airflow to blow all the pollutants in the cavity of the hydraulic valve 8 that are brushed or moved by the cleaning brush rod 54 out of the inner cavity of the hydraulic valve 8, thereby cleaning the inner cavity of the hydraulic valve 8 and avoiding the pollutants remaining in the hydraulic valve 8. The pollutants in the inner cavity of 8 affect the irradiation of the laser during detection, thereby improving the accuracy of the detection result. Subsequently, the driving component 4 drives the cleaning component 5 and the detection module 6 to move upward, and pulls out the cleaning brush rod 54 from the cleaned inner cavity of the hydraulic valve 8. Subsequently, the positioning component 3 under the cleaning component 5 releases the fixation of the hydraulic valve 8, so that the hydraulic valve 8 arrives under the detection module 6 under the conveyor belt 28. At the same time, the second hydraulic valve 8 is also moved under the cleaning component 5. At this time, the two groups of positioning components 3 fix the first hydraulic valve 8 and the second hydraulic valve 8 respectively. The driving component 4 drives the cleaning component 5 and the detection module 6 to move downward again, and the cleaning component 5 repeats the above steps to clean the inner cavity of the second hydraulic valve 8. At the same time, the laser probe 61 of the detection module 6 Insert it into the inner cavity of the first hydraulic valve 8 that has been cleaned, and detect the size of the inner cavity of the hydraulic valve 8 by laser. When the cleaning component 5 completes the cleaning of the inner cavity of the second hydraulic valve 8, the detection module 6 also completes the detection of the first hydraulic valve 8. Then the two groups of positioning components 3 release the fixation of the two hydraulic valves 8 at the same time, and the conveyor belt 28 conveys the hydraulic valves 8 that have completed the detection to the unloading end 12 for unloading. At the same time, the second hydraulic valve 8 that has completed the cleaning is moved under the detection module 6, and the third hydraulic valve 8 to be cleaned is moved under the cleaning component 5, so as to repeat the above steps, and so on, to complete the detection of the inner cavity size of this batch of hydraulic valves 8. When it is necessary to detect hydraulic valves 8 of other sizes, the work of the conveying mechanism 2 is suspended, and the adjusting rod 26 is rotated in the opposite direction.The movable frame 22 is driven away from the fixed frame 21 to increase the distance between the fixed frame 21 and the movable frame 22, which is used to detect a larger hydraulic valve 8, or the movable frame 22 is driven close to the fixed frame 21 by rotating the adjustment rod 26 in the positive direction to reduce the distance between the fixed frame 21 and the movable frame 22, which is used to detect a smaller hydraulic valve 8, thereby increasing the applicability of the device. After the adjustment is completed, the conveying mechanism 2 continues to work.

[0021] The difference from the above embodiment is that slide rails 13 are fixedly installed on both sides of the detection cabinet 1, and the slide rails 13 are located on the side of the fixed frame 21 facing the movable frame 22. A slide groove 14 is provided at the bottom of the detection cabinet 1, and the slide groove 14 is located on the side of the movable frame 22 away from the fixed frame 21. The bottom of the fixed frame 21 is fixedly connected to the bottom of the detection cabinet 1, and the bottom of the movable frame 22 is slidably connected to the slide rails 13 through a slider, and a plurality of driven rollers 23 are rotatably connected to both the fixed frame 21 and the movable frame 22.

[0022] When the adjusting rod 26 rotates, the moving frame 22 slides on the slide rail 13 via the slider.

[0023] The difference from the above embodiment is that the conveying mechanism 2 also includes a fixed seat 24, and the two fixed seats 24 are respectively fixedly installed on both sides of the detection cabinet 1, and the mobile frame 22 is located between the fixed frame 21 and the fixed seat 24, wherein a slide bar 25 is rotatably connected between the fixed seat 24 and the fixed frame 21 near the unloading end 12, and the slide bar 25 is prism-shaped, and a shaft sleeve 221 is rotatably connected to the mobile frame 22, and the shaft sleeve 221 is slidably installed on the slide bar 25, and a driving roller 251 is rotatably installed on both the fixed frame 21 and the shaft sleeve 221, and when the slide bar 25 rotates, it can drive the driving roller 251 to rotate, and the conveyor belt 28 sequentially bypasses the driven roller 23 and the driving roller 251, thereby being installed on the fixed frame 21 and the mobile frame 22.

[0024] Among them, when the adjusting rod 26 is rotated to adjust the distance between the fixed frame 21 and the movable frame 22, the movable frame 22 slides on the slide rail 13, and at the same time, it will slide on the slide rod 25 between the fixed seat 24 and the fixed frame 21 through the shaft sleeve 221. When the conveying mechanism 2 needs to work, the prismatic slide rod 25 can drive the two driving rollers 251 to rotate, and drive the two conveyor belts 28 to rotate from the loading end 11 to the unloading end 12 with the cooperation of the driven roller 23.

[0025] The difference from the above embodiment is that an adjusting rod 26 is provided on each of the two fixed seats 24, and the two ends of the adjusting rod 26 are rotatably connected to the fixed frame 21 and the fixed seat 24 respectively, and the two ends of the adjusting rod 26 pass through the fixed frame 21 and the fixed seat 24 respectively, and a transmission gear 261 is coaxially fixedly installed on one end of the two adjusting rods 26 passing through the fixed seat 24, and the two transmission gears 261 are connected by a toothed belt 262, and a hand wheel 263 is fixedly connected to the other end of one of the adjusting rods 26, and a thread is provided on the adjusting rod 26, and the two ends of the movable frame 22 are respectively matched on the two adjusting rods 26 through threaded sleeves.

[0026] When it is necessary to adjust the distance between the fixed frame 21 and the movable frame 22, the hand wheel 263 is manually turned to drive one of the adjusting rods 26 to rotate. At the same time, the adjusting rod 26 cooperates with the transmission gear 261 to drive the other adjusting rod 26 to rotate synchronously, so that the adjusting rod 26 drives the movable frame 22 thereon to move through the thread.

[0027] The difference from the above-mentioned embodiment lies in that a plurality of baffles 29 are fixedly connected to the upper sides of the fixed frame 21 and the movable frame 22, and two intervals are arranged between the baffles 29 on the movable frame 22, and two laser sensors 211 are fixedly installed on the side of the fixed frame 21 away from the movable frame 22, and the two laser sensors 211 correspond to two groups of positioning components 3 respectively.

[0028] Among them, when the hydraulic valve 8 moves to the bottom of the cleaning component 5 or the bottom of the detection module 6, the corresponding laser sensor 211 will be triggered. The triggered laser sensor 211 sends a signal to the positioning component 3, so that the positioning component 3 will fix the hydraulic valve 8 that triggers the laser sensor 211, so that the cleaning brush rod 54 and the cleaning head 53 of the cleaning component 5 and the laser probe 61 of the detection module 6 can be accurately inserted into the inner cavity of the hydraulic valve 8 to clean and detect the inner cavity of the hydraulic valve 8.

[0029] The difference from the above embodiment is that the driving assembly 4 includes a mounting frame 41 and a linear motor 42, the mounting frame 41 is slidably installed on the slide groove 14, fixing bolts 411 are installed on both sides of the bottom of the mounting frame 41, the linear motor 42 is fixedly installed on the upper part of the mounting frame 41, and a connecting plate 43 is movably installed on the linear motor 42.

[0030] When the inner cavity of the hydraulic valve 8 needs to be cleaned and inspected, the linear motor 42 of the drive assembly 4 drives the connecting plate 43 to move downward. When the cleaning and inspection of the hydraulic valve 8 are completed, the linear motor 42 drives the connecting plate 43 to move upward. When the adjusting rod 26 is rotated in the opposite direction to increase the distance between the fixed frame 21 and the movable frame 22, the fixing bolt 411 needs to be loosened first, and the mounting frame 41 is pushed to move a corresponding distance toward the end of the slide 14 away from the movable frame 22, and then the fixing bolt 411 is tightened. 11, so that the mounting frame 41 is fixed in the detection cabinet 1. When the adjustment rod 26 is rotated forward to reduce the distance between the fixed frame 21 and the movable frame 22, the fixing bolt 411 must be loosened first, and the mounting frame 41 is pushed to move a corresponding distance toward the end of the slide 14 close to the movable frame 22, and then the fixing bolt 411 is tightened to fix the mounting frame 41 in the detection cabinet 1, thereby ensuring that the cleaning head 53 and the cleaning brush rod 54 of the cleaning assembly 5 and the laser probe 61 of the detection module 6 can be inserted into the inner cavity of the hydraulic valve 8 of the new size.

[0031] The difference from the above embodiment is that the cleaning assembly 5 also includes a motor 51 and a collecting tank 7. The motor 51 is fixedly mounted on one side of the connecting plate 43 close to the feeding end 11. A connecting rod 52 is coaxially fixedly connected to the output shaft of the motor 51. The connecting rod 52 is hollow. The lower end of the connecting rod 52 is rotatably connected to the cleaning head 53 and penetrates the cleaning head 53.

A plurality of bristles are fixedly connected to the lower end of the cleaning brush rod 54. The collecting tank 7 is movably installed below the conveying mechanism 2 and corresponds to the cleaning head 53.

[0032] When the device is used, the connecting port 533 is connected to the air pump. When the connecting plate 43 moves downward, the motor 51 drives the connecting rod 52 to rotate on the cleaning head 53, and the cleaning head 53 remains fixed under the action of the fixing rod 531. At this time, the adjusting bolt 55 is inserted into one of the locking holes 541 of the cleaning brush rod 54, and the cleaning brush rod 54 is fixedly connected to the connecting rod 52, so that the cleaning brush rod 54 can be driven by the connecting rod 52 to rotate to obtain the cleaning brush rod 54 to clean the pollutants remaining in the inner cavity of the hydraulic valve 8 through the bristles at the lower end. Some of the pollutants brushed off by the cleaning brush rod 54 will fall into the collecting tank 7. After the cleaning work is completed and the cleaning brush rod 54 stops rotating, the air pump delivers air to the air jet port 532, and the air jet port 532 then releases the air Air is sprayed into the inner cavity of the hydraulic valve 8, and the pollutants in the inner cavity of the hydraulic valve 8 that are brushed or moved by the cleaning brush rod 54 are blown into the collecting tank 7. At the same time, the bristles on the cleaning brush rod 54 are blown down to blow away the pollutants on the bristles, thereby cleaning the inner cavity of the hydraulic valve 8. Then the air jet 532 stops jetting, and the driving component 4 lifts the cleaning component 5 to pull out the cleaning head 53 and the cleaning brush rod 54. When the hydraulic valve 8 to be cleaned becomes longer, the adjusting bolt 55 is unscrewed, and the other part of the cleaning brush rod 54 stored in the connecting rod 52 is pulled out, and the adjusting bolt 55 is screwed into another locking hole 541 to fix the cleaning brush rod 54 in the connecting rod 52, thereby increasing the length of the cleaning brush rod 54 to adapt to hydraulic valves 8 of other sizes.

After the detection is completed, the connecting plate 43 of the driving component 4 moves upward and the laser probe 61 is pulled out.

[0035] The difference from the above embodiment is that the positioning assembly 3 includes a support base 31 and a driving cylinder 32.

[0038] When the conveying mechanism 2 is started, the driving motor 27 drives the slide bar 25 to rotate through the transmission belt 271 , and the slide bar 25 drives the conveying belt 28 to rotate through the driving roller 251 .

[0039] Working principle: When in use, the device is first started, and the conveyor belts 28 on the fixed frame 21 and the mobile frame 22 are started synchronously, and begin to rotate from the loading end 11 to the unloading end 12. At the loading end 11 of the detection cabinet 1, a number of hydraulic valves 8 to be tested are placed one by one on the conveyor belt 28, so that the side of the hydraulic valve 8 is located between the fixed frame 21 and the mobile frame 22, and the bottom sides of the hydraulic valve 8 are placed on the conveyor belts 28 of the fixed frame 21 and the mobile frame 22 respectively, so that the inner cavity of the hydraulic valve 8 is in the gap between the fixed frame 21 and the mobile frame 22. When the first hydraulic valve 8 to be tested moves to the bottom of the cleaning component 5, the positioning component 3 corresponding to the cleaning component 5 fixes the hydraulic valve 8, so that the hydraulic valve 8 cannot move, while other hydraulic valves 8 continue to follow the conveyor belt 28 moves, after the first hydraulic valve 8 is fixed, the driving component 4 drives the cleaning component 5 and the detection module 6 to move downward synchronously, so that the cleaning brush rod 54 under the cleaning head 53 is inserted into the inner cavity of the hydraulic valve 8, and the cleaning brush rod 54 rotates at the same time to clean the inner cavity of the hydraulic valve 8 and brush away the pollutants remaining in the inner cavity of the hydraulic valve 8. When the cleaning head 53 is also inserted into the inner cavity of the hydraulic valve 8 so that the air jet 532 is located at the upper end of the inner cavity of the hydraulic valve 8, the cleaning brush rod 54 completes the cleaning of the inner cavity of the hydraulic valve 8 and stops rotating. At the same time, the air jet 532 ejects airflow to blow all the pollutants in the cavity of the hydraulic valve 8 that are brushed or moved by the cleaning brush rod 54 out of the inner cavity of the hydraulic valve 8, thereby cleaning the inner cavity of the hydraulic valve 8 and avoiding the pollutants remaining in the hydraulic The pollutants in the inner cavity of the valve 8 affect the irradiation of the laser during detection, thereby improving the accuracy of the detection result. Subsequently, the driving component 4 drives the cleaning component 5 and the detection module 6 to move upward, and pulls out the cleaning brush rod 54 from the cleaned inner cavity of the hydraulic valve 8. Subsequently, the positioning component 3 under the cleaning component 5 releases the fixation of the hydraulic valve 8, so that the hydraulic valve 8 arrives under the detection module 6 under the conveyor belt 28. At the same time, the second hydraulic valve 8 is also moved under the cleaning component 5. At this time, the two groups of positioning components 3 fix the first hydraulic valve 8 and the second hydraulic valve 8 respectively. The driving component 4 drives the cleaning component 5 and the detection module 6 to move downward again, and the cleaning component 5 repeats the above steps to clean the inner cavity of the second hydraulic valve 8. At the same time, the laser probe 61 of the detection module 6 Insert it into the inner cavity of the first hydraulic valve 8 that has been cleaned, and detect the size of the inner cavity of the hydraulic valve 8 by laser. When the cleaning component 5 completes the cleaning of the inner cavity of the second hydraulic valve 8, the detection module 6 also completes the detection of the first hydraulic valve 8. Then the two groups of positioning components 3 release the fixation of the two hydraulic valves 8 at the same time, and the conveyor belt 28 conveys the hydraulic valves 8 that have completed the detection to the unloading end 12 for unloading. At the same time, the second hydraulic valve 8 that has completed the cleaning is moved under the detection module 6, and the third hydraulic valve 8 to be cleaned is moved under the cleaning component 5, so as to repeat the above steps, and so on, to complete the detection of the inner cavity size of this batch of hydraulic valves 8. When it is necessary to detect hydraulic valves 8 of other sizes, the work of the conveying mechanism 2 is suspended, and the adjusting rod 26 is rotated in the opposite direction.The movable frame 22 is driven away from the fixed frame 21 to increase the distance between the fixed frame 21 and the movable frame 22, which is used to detect a larger hydraulic valve 8, or the movable frame 22 is driven close to the fixed frame 21 by rotating the adjustment rod 26 in the positive direction to reduce the distance between the fixed frame 21 and the movable frame 22, which is used to detect a smaller hydraulic valve 8, thereby increasing the applicability of the device. After the adjustment is completed, the conveying mechanism 2 continues to work.
