Description

Technical Field

[0001] This invention relates to the field of hydraulic valve assembly technology, specifically to an automatic assembly equipment for hydraulic valve assemblies. Background Technology

[0002] Manual hydraulic directional valves are key components in hydraulic systems used to change the direction of fluid flow through manual operation. With the development of industrial automation and mechanical engineering, higher demands are placed on the control precision and efficiency of hydraulic systems. Manual hydraulic directional valves, with their simple structure, low cost, and intuitive operation, play an indispensable role in many application scenarios. These valves typically consist of a valve body, valve core, valve stem or knob, spring, and seals. The operator directly applies mechanical force to the valve stem to move the valve core, thereby opening, closing, or reversing the fluid flow. In the production of manual hydraulic valves, the assembly of the hydraulic valve body and the hydraulic valve stem is a crucial step.

[0003] The existing assembly of hydraulic valve bodies and hydraulic valve stems relies on manual or semi-automated production methods. Due to the slow speed of manual assembly, it is difficult to meet the requirements of large-scale production. In addition, the large error of human operation leads to inconsistent product quality. Furthermore, it is impossible to control the quality of products and record data during the assembly process, which is not conducive to the traceability and improvement of subsequent problems. In order to improve the assembly efficiency of existing hydraulic valve bodies and hydraulic valve stems and strengthen product quality control in the hydraulic valve production process, we propose an automatic assembly equipment for hydraulic valve components.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8 This invention provides a technical solution: an automatic assembly equipment for hydraulic valve components, including an assembly table 1, an annular guide rail conveyor belt 2 installed on the top center of the assembly table 1, six sets of conveyor plates 43 installed on the annular guide rail conveyor belt 2, a placement plate 44 fixedly installed on the conveyor plate 43, a hydraulic valve housing 45 provided on the top side of the placement plate 44, a hydraulic valve stem feeder 3 provided on the rear center of the annular guide rail conveyor belt 2, a hydraulic valve stem 46 clamped on the hydraulic valve stem feeder 3, a pin assembly assembly provided on the rear right side of the annular guide rail conveyor belt 2, an internal valve body detection assembly provided on the front right side of the annular guide rail conveyor belt 2, an external valve body detection assembly provided on the front center of the annular guide rail conveyor belt 2, and a clamping assembly also installed on the rear inner side of the assembly table 1.

[0028] This automated hydraulic valve assembly equipment features a circular guide rail conveyor belt 2 installed at the top center of the assembly table 1. Six sets of conveyor plates 43 slide along the conveyor belt 2, which in turn move the placement plates 44 on the conveyor plates 43. First, the hydraulic valve housing 45 is placed into the first set of placement plates 44. Then, the hydraulic valve rod 46, held by the hydraulic valve rod feeder 3, is inserted into the hydraulic valve housing 45 on the second set of placement plates 44. After insertion, the hydraulic valve rod 46 is clamped by a clamping assembly to prevent shaking. It is then conveyed to the next position where the pin assembly assembly assembles the pins. After assembly, it is then conveyed to the valve body internal inspection assembly and valve body external inspection assembly for inspection of the valve body's interior and exterior. This assembly method is fully automated, enabling continuous cyclic production, improving assembly efficiency, meeting the requirements of large-scale production, and ensuring the final product quality through dual inspection.

[0029] The pin assembly includes an automatic pin insertion machine 4 and a vibrating feeder 5. Both the automatic pin insertion machine 4 and the vibrating feeder 5 are fixedly installed on the top of the assembly table 1. A pin dropping channel 33 is fixedly connected to the vibrating feeder 5. An installation plate 9 is also provided between the automatic pin insertion machine 4 and the vibrating feeder 5. A cylinder 10 is installed on the bottom front side of the installation plate 9. A sliding plate 48 is slidably installed on the front side of the installation plate 9. The output shaft end of the cylinder 10 is fixedly connected to the bottom of the sliding plate 48. A cylinder 29 is fixedly installed on the top front side of the sliding plate 48. A slide rail 28 is fixedly installed on the top front side of the sliding plate 48. A sliding plate 30 is slidably installed on the slide rail 28. A pin transfer block 31 is fixedly connected to the front side of the sliding plate 30. A push plate 32 is fixedly connected to the output shaft end of the cylinder 29. The front end of the push plate 32 is fixedly connected to the sliding plate 30.

[0030] When the pin assembly is in use, the pin is fed by the vibrating feeder 5 and sent into the pin transfer block 31 through the pin drop channel 33. Then, the pusher plate 32 is pushed by the cylinder 5 29, which drives the sliding plate 30 to slide on the slide rail 3 28, which moves the pin transfer block 31 to the pin insertion point of the automatic pin insertion machine 4. The sliding plate 48 is driven by the cylinder 1 10 to slide downward on the mounting plate 9, so that the pin transfer block 31 abuts against the pin insertion point on the hydraulic valve housing 45. Then, the automatic pin insertion machine 4 inserts the pin into the valve body.

[0031] The valve body internal detection assembly includes a mounting platform 14, which is fixedly mounted on the top of the assembly platform 1. A cylinder 17 is fixedly mounted on the front side of the top of the mounting platform 14. A slide rail 15 is fixedly connected to the top of the mounting platform 14. A sliding plate 18 is slidably connected to the slide rail 15. The output shaft end of the cylinder 17 is fixedly connected to the front side of the sliding plate 18. A mounting plate 16 is fixedly connected to the rear side of the top of the sliding plate 18. A cylinder 19 is fixedly mounted on the rear side of the mounting plate 16. A CCD vision inspection camera 20 is mounted on the output shaft end of the cylinder 19.

[0032] When the internal inspection component of the valve body is in use, the cylinder 3 17 pushes the sliding plate 18 to slide on the slide rail 2 15, and then the cylinder 4 19 pushes the CCD vision inspection camera 20 to be inserted into the valve body to inspect for size and crack defects.

[0033] The valve body external inspection component includes a mounting bracket 6, which is fixedly installed on the top front side of the assembly table 1. A CCD vision inspection camera 49 is fixedly installed inside the front side of the mounting bracket 6. A lifting cylinder 8 is fixedly installed on the top of the mounting bracket 6. A connecting plate 21 is fixedly connected to the output shaft end of the lifting cylinder 8. A sliding plate 26 is fixedly connected to the front and rear sides of the top of the connecting plate 21. A limiting rod 25 is slidably passed through the left and right sides of the sliding plate 26. The top end of the limiting rod 25 is fixedly connected to the bottom side of the top of the mounting bracket 6. A limiting plate 27 is fixedly connected to the bottom end of the limiting rod 25. A rotating clamping mechanism is installed at the bottom of the limiting plate 27.

[0034] The rotating clamping mechanism includes a rotating cylinder 22, which is fixedly installed at the bottom of the connecting plate 21. The output shaft end of the rotating cylinder 22 is fixedly connected to a gripper cylinder 23, and two sets of grippers 24 are installed on the gripper cylinder 23.

[0035] The lifting cylinder 8 pushes the connecting plate 21, which in turn drives the rotating cylinder 22 and the gripper cylinder 23 to slide down. The two sets of grippers 24 of the gripper cylinder 23 then clamp the valve body. The lifting cylinder 8 then pulls the valve body upward, and the rotating cylinder 22 rotates the valve body. The CCD vision inspection camera 49 detects the outer side of the valve body and its posture during rotation. During the sliding of the connecting plate 21, the sliding plate 26 slides on the limiting rod 25 and is limited by the limiting plate 27 at the bottom of the limiting rod 25.

[0036] The clamping assembly includes cylinder 2 13. A fixed plate 11 is fixedly connected inside the assembly table 1. A slide rail 12 is fixedly installed on the rear side of the fixed plate 11. Cylinder 2 13 is fixedly installed on the right side of the fixed plate 11. A sliding plate 4 35 is slidably connected on the slide rail 12. A locking rod 36 is fixedly connected to the right side of the sliding plate 4 35. A locking block 37 is fixedly connected to the output shaft end of cylinder 2 13. The locking block 37 abuts against the locking rod 36. A sliding clamping mechanism is installed on the rear side of the sliding plate 4 35.

[0037] The sliding clamping mechanism includes cylinder six 34, which is fixedly installed at the bottom rear side of sliding plate four 35. Sliding plate five 38 is slidably installed at the rear side of sliding plate four 35. The output shaft end of cylinder six 34 is fixedly connected to the bottom of sliding plate five 38. Gripper cylinder two 40 is fixedly installed at the top of sliding plate five 38. Two sets of clamping plates 41 are installed at the top of clampper cylinder two 40. Gripper two 42 is fixedly connected to clamping plate 41.

[0038] A limiting block 39 is fixedly connected to the left side of the fixing plate 11.

[0039] A fixing rod 47 is fixedly connected to the side of the placement plate 44 near the gripper 42.

[0040] When the clamping assembly is in use, after the hydraulic valve stem 46 is inserted into the hydraulic valve housing 45 on the second set of placement plates 44 on the rear side, the cylinder six 34 pushes the sliding plate five 38 to slide upward on the sliding plate four 35. Then, the sliding plate four 35 drives the two sets of clamping plates 41 to move closer to each other, and the two sets of grippers two 42 simultaneously clamp the hydraulic valve stem 46 and the fixing rod 47. When the hydraulic valve housing 45 is transported to the pin assembly position by the placement plate 44, the sliding plate four 35 is simultaneously driven to slide to the right on the slide rail one 12. After the pin assembly is completed, the locking block 37 fixedly connected to the output shaft end of the cylinder two 13 pushes the locking rod 36, thereby pushing the sliding plate four 35 to slide to the left on the slide rail one 12 until the sliding plate four 35 abuts against the limit block 39, and enters the next conveying.

[0041] Equipment support bases 7 are installed at the four corners of the bottom of the assembly table 1 to support the equipment.

[0042] Working principle: This automatic assembly equipment for hydraulic valve components has an annular guide rail conveyor belt 2 installed on the top center of the assembly table 1. Six sets of conveyor plates 43 slide along the annular guide rail conveyor belt 2, which in turn drives the placement plates 44 on the conveyor plates 43. First, the hydraulic valve housing 45 is placed into the first set of placement plates 44. Then, the hydraulic valve rod feeder 3 inserts the clamped hydraulic valve rod 46 into the hydraulic valve housing 45 on the second set of placement plates 44. After the hydraulic valve rod 46 is inserted into the hydraulic valve housing 45, the cylinder 6 34 pushes the sliding plate 5 38 to slide upward on the sliding plate 4 35. Then, the sliding plate 4 35 drives the two sets of clamping plates 41 to move closer to each other, and the two sets of grippers 2 42 simultaneously clamp the hydraulic valve rod 46 and the fixing rod 47 to prevent the hydraulic valve rod 46 from shaking during the conveying process. When the hydraulic valve housing 45 is conveyed to the pin assembly position by the placement plate 44, the sliding plate 4 35 is simultaneously driven to slide to the right on the slide rail 1 12.

[0043] At the pin assembly position, the pin is conveyed by the vibrating feeder 5 and fed into the pin transfer block 31 through the pin dropping channel 33. Then, the push plate 32 is pushed by the cylinder 5 29, which drives the sliding plate 30 to slide on the slide rail 3 28, and moves the pin transfer block 31 to the pin insertion position of the automatic pin insertion machine 4. The sliding plate 48 is driven by the cylinder 1 10 to slide downward on the mounting plate 1 9, so that the pin transfer block 31 abuts against the pin insertion position on the hydraulic valve housing 45. Then, the automatic pin insertion machine 4 inserts the pin into the valve body. After the pin assembly is completed, the locking block 37 fixedly connected to the output shaft end of the cylinder 2 13 pushes the locking rod 36, thereby pushing the sliding plate 4 35 to slide to the left on the slide rail 1 12 until the sliding plate 4 35 abuts against the limit block 39, and enters the next conveying.

[0044] After assembly, the valve body is transported to the first inspection position. Cylinder 3 (17) pushes sliding plate 18 to slide on slide rail 2 (15). Then, cylinder 4 (19) pushes CCD vision inspection camera 20 to insert into the valve body to inspect for dimensions and cracks. Next, the valve body is transported to the second inspection position. Lifting cylinder 8 pushes connecting plate 21, which in turn drives rotating cylinder 22 and gripper cylinder 23 to slide down. The two sets of grippers 24 of gripper cylinder 23 then clamp the valve body. Finally, lifting cylinder 8 pulls the valve body upwards. The rotation of cylinder 22 drives the valve body to rotate, and CCD vision inspection camera 49 detects the outer side of the valve body and its posture during rotation. During the sliding process of connecting plate 21, sliding plate 26 slides on limit rod 25 and is limited by limit plate 27 at the bottom of limit rod 25. After the second inspection, the valve body is transported to the unloading position to wait for unloading. This assembly method is fully automated, realizes continuous production, improves assembly efficiency, meets the requirements of large-scale production, and ensures the final product quality through dual inspection.
