Description

Technical Field

[0001] This utility model relates to the field of valve body assembly technology, specifically a flipping detection mechanism for valve body assembly. Background Technology

[0002] Hydraulic systems are an indispensable part of modern industry, widely used in various mechanical equipment such as construction machinery, agricultural machinery, aerospace, automobile manufacturing, and various automated production lines. As the core control component of a hydraulic system, the hydraulic valve plays a crucial role, responsible for regulating the direction, pressure, and flow of hydraulic oil, thereby controlling the actions of actuators (such as hydraulic cylinders and hydraulic motors). Assembling the valve body shell and valve core into a complete valve body is a key step in hydraulic valve production, requiring not only high precision to ensure proper fit between components but also strict sealing and reliability standards.

[0003] In existing hydraulic valve production, after the valve body shell and valve core are assembled into a valve body, the appearance and operational performance of the product are mainly inspected manually. However, manual inspection suffers from low efficiency, insufficient reliability, and high labor costs. This not only fails to meet the needs of large-scale production but also results in low accuracy of final product quality inspection, affecting product reputation. To improve the inspection efficiency and accuracy of existing valve body assembly, we propose a flipping inspection mechanism for valve body assembly. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a valve body assembly flipping detection mechanism, including a worktable 1, a longitudinal moving module 6 fixedly installed on the top left side of the worktable 1, a feeding component installed on the longitudinal moving module 6, a transverse moving module 4 fixedly installed on the top right side of the worktable 1, a flipping detection component installed on the transverse moving module 4, two sets of mounting plates 5 fixedly installed on the top rear side of the worktable 1, a transverse moving module 2 fixedly installed on the top front side of the mounting plate 5, a CCD vision inspection camera 11 fixedly installed on the rear bottom side of the transverse moving module 2, a clamping and transferring component installed on the transverse moving module 2, and an internal detection component installed on the top of the worktable 1 behind the transverse moving module 2.

[0026] This valve body assembly flipping inspection mechanism uses a longitudinal moving module 6 to slide the feeding assembly back and forth to deliver the assembled valve body to the inspection position. Then, an internal inspection assembly inspects the inside of the valve body for defects and damage. After the internal inspection is completed, a transverse moving module 2 slides left and right to hold and transfer the valve body to the flipping inspection assembly. The flipping inspection assembly performs a reciprocating flipping test on the valve body, and a CCD vision inspection camera 11 inspects the outer surface of the valve body and its operational performance during the flipping process. Finally, a transverse moving module 4 slides the flipping inspection assembly to the right, allowing the valve body to be removed from the flipping inspection assembly and proceed to the next process. This inspection mechanism operates fully automatically without human intervention, meeting the needs of large-scale production and achieving high accuracy in final product quality inspection.

[0027] The feeding assembly includes a rotary cylinder 22. A sliding plate 4 21 is mounted on the top of the longitudinal moving module 6. The rotary cylinder 22 is fixedly mounted on the top of the sliding plate 4 21. A placement plate 23 is fixedly connected to the output shaft end of the rotary cylinder 22. A valve body housing 24 is placed on the top side of the placement plate 23. A valve stem 25 is inserted into the right side of the valve body housing 24.

[0028] When the feeding assembly is in use, the output end of the rotary cylinder 22 is connected to the placement plate 23. The valve body assembled with the valve body housing 24 and valve stem 25 is placed on the placement plate 23. The rotary cylinder 22 can rotate the placement plate 23, so that the valve body on the placement plate 23 can rotate and adjust its position for easy clamping. By sliding the sliding plate 4 21 back and forth through the longitudinal moving module 6, the rotary cylinder 22 is driven to slide back and forth, thereby driving the placement plate 23 and the valve body to slide to the detection position.

[0029] The flipping detection assembly includes a gripper cylinder 35, a sliding plate 26 mounted on the top of the lateral movement module 4, a fixing plate 27 fixedly connected to the top side of the sliding plate 26, two sets of mounting plates 28 fixedly connected to the top rear side of the fixing plate 27, a rotating column 34 rotatably mounted between the two sets of mounting plates 28, a gripper cylinder 35 fixedly mounted on the rotating column 34, two sets of grippers 36 mounted on the top of the gripper cylinder 35, and a drive mechanism mounted on the top front side of the fixing plate 27.

[0030] The drive mechanism includes a drive motor 30, which is fixedly mounted on the front side of the mounting plate 29. A rotating rod 32 is rotatably connected between the mounting plate 29 and the mounting plate 28 located on the front side. The output shaft end of the drive motor 30 is fixedly connected to the front end of the rotating rod 32, and the rear end of the rotating rod 32 is fixedly connected to the front end of the rotating column 34. A limit mechanism is also provided between the mounting plate 29 and the mounting plate 28 located on the front side.

[0031] The limiting mechanism includes two sets of limiting rods 31. The outer surface of the rotating rod 32 is also fixedly connected with a protrusion 33. The two sets of limiting rods 31 are respectively set on the left and right sides of the protrusion 33, and both sets of limiting rods 31 are fixedly connected to the top of the fixed plate 3 27. The bottom right side of the protrusion 33 abuts against the top side of one set of limiting rods 31.

[0032] When using the flip detection component, the assembled valve body is placed between two sets of grippers 36. The two sets of grippers 36 are clamped by gripper cylinders 35. Then, the drive motor 30 rotates the rotating rod 32, which in turn rotates the rotating column 34, causing the gripper cylinders 35 on the rotating column 34 to rotate. When the rotating rod 32 rotates, the two sides of the protrusions 33 abut against the tops of the two sets of limiting rods 31, limiting the rotation of the rotating rod 32. This allows the rotating rod 32 to rotate back and forth at a certain angle, so that the valve body clamped by the grippers 36 can flip back and forth within a certain angle. After the flip test is completed, the horizontal moving module 4 slides the sliding plate 26 to the right, which in turn moves the valve body clamped by the grippers 36 at the top of the sliding plate 26 to the right, where it is removed and proceeds to the next process.

[0033] The clamping and transferring assembly includes a fixed plate 8, a sliding plate 7 mounted on the front side of the transverse moving module 2, a fixed plate 8 fixedly mounted on the front side of the sliding plate 7, a fixed plate 9 fixedly connected to the top right side of the fixed plate 8, a cylinder 10 fixedly mounted on the fixed plate 29, a sliding plate 3 17 slidably mounted on the right side of the fixed plate 8, the output shaft end of the cylinder 10 fixedly connected to the top right side of the sliding plate 3 17, a gripper cylinder 18 fixedly mounted on the bottom right side of the sliding plate 3 17, and two sets of grippers 19 mounted on the right side of the gripper cylinder 18.

[0034] When the clamping and transfer assembly is in use, the horizontal moving module 12 drives the sliding plate 17 to slide left and right, thereby driving the fixed plate 18 and fixed plate 29 to slide left and right. The cylinder 10 pushes the sliding plate 317 to slide down on the fixed plate 18, and drives the gripper cylinder 18 on the right side of the sliding plate 317 to slide down. The two sets of grippers 19 on the gripper cylinder 18 clamp the valve body that has completed the internal detection and enter the flip detection.

[0035] The internal detection assembly includes cylinder 16. A mounting bracket 12 is fixedly installed on the top rear side of the worktable 1. Cylinder 16 is fixedly installed on the top rear side of the mounting bracket 12. A sliding plate 13 is slidably installed on the top of the mounting bracket 12. The output shaft end of cylinder 16 is fixedly connected to the rear side of the sliding plate 13. An insertion detection mechanism is installed on the top of the sliding plate 13.

[0036] The insertion detection mechanism includes a wireless transmission device 15. A mounting plate 14 is fixedly connected to the right side of the sliding plate 13. The wireless transmission device 15 is fixedly installed on the right side of the mounting plate 14. An insertion rod is installed at the front end of the wireless transmission device 15, and a CCD vision inspection camera 20 is installed at the front end of the insertion rod.

[0037] When the internal inspection component is in use, the cylinder 2 16 pushes the sliding plate 2 13 to slide on the mounting bracket 12, and drives the mounting plate 2 14 of the sliding plate 2 13 to slide forward, thereby causing the wireless transmission device 15 on the mounting plate 2 14 to slide forward, so that the insertion rod at the front end of the wireless transmission device 15 is inserted into the valve body, and the CCD vision inspection camera 20 installed at the front end of the insertion rod detects whether there are defects and damage inside the valve body.

[0038] Both jaw 19 and jaw 36 have elastic rubber pads fixedly connected to their outer surfaces to prevent scratching the valve body during clamping.

[0039] Several support legs 3 are fixedly installed at the bottom of the workbench 1 to support the equipment.

[0040] Working principle: This valve body assembly flipping detection mechanism has a rotating cylinder 22 with a placement plate 23 connected to its output end. The valve body assembled with the valve body shell 24 and valve stem 25 is placed on the placement plate 23. The rotating cylinder 22 can rotate the placement plate 23, so that the valve body on the placement plate 23 can rotate and adjust its position for easy clamping. By sliding the sliding plate 21 back and forth through the longitudinal moving module 6, the rotating cylinder 22 is driven to slide back and forth, thereby driving the placement plate 23 and the valve body to slide to the detection position. Then, the cylinder 16 pushes the sliding plate 13 to slide on the mounting bracket 12, and drives the mounting plate 14 of the sliding plate 13 to slide forward, thereby causing the wireless transmission device 15 on the mounting plate 14 to slide forward, so that the insertion rod at the front end of the wireless transmission device 15 is inserted into the valve body. The CCD vision inspection camera 20 installed at the front end of the insertion rod detects whether there are defects and damage inside the valve body.

[0041] After the internal test is completed, the horizontal moving module 12 drives the sliding plate 7 to slide left and right, thereby causing the fixed plate 8 and fixed plate 2 9 to slide left and right. The cylinder 10 pushes the sliding plate 3 17 to slide downward on the fixed plate 8, and causes the gripper cylinder 18 on the right side of the sliding plate 3 17 to slide downward. The two sets of grippers 19 on the gripper cylinder 18 clamp the valve body that has completed the internal test, and then place the assembled valve body between the two sets of grippers 2 36. The gripper cylinder 2 35 clamps the two sets of grippers 2 36 to hold the valve body, and then... The drive motor 30 rotates the rotating rod 32, which in turn rotates the rotating column 34, and drives the gripper cylinder 35 on the rotating column 34 to rotate. When the rotating rod 32 rotates, the two sides of the protrusion 33 abut against the top of the two sets of limiting rods 31 to limit the rotation of the rotating rod 32, so that the rotating rod 32 can only rotate back and forth at a certain angle. This allows the valve body clamped by the gripper 36 to be flipped back and forth within a certain angle. The CCD vision inspection camera 11 is used to detect whether there are defects on the outer surface of the valve body and the operational performance during the flipping process.

[0042] After the flipping experiment is completed, the sliding plate 26 is slid to the right by the lateral movement module 24, which in turn moves the valve body held by the gripper 26 on the top of the sliding plate 26 to the right, so that the valve body is removed and enters the next process. The inspection mechanism operates automatically throughout the process without human intervention. The inner and outer surfaces and flipping posture of the valve body are inspected by the CCD vision inspection camera 11 and the CCD vision inspection camera 20. This not only meets the needs of large-scale production, but also has a high accuracy rate in the final product quality inspection.
