Description

Technical Field

[0001] This utility model relates to the field of valve body assembly technology, specifically to a valve body shell feeding device 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 stem 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 technologies, valve body shell loading typically relies on manual operation or semi-automated equipment. This loading method is time-consuming, labor-intensive, and inefficient, and cannot achieve continuous loading, thus reducing production efficiency. Furthermore, existing loading devices use grippers on both sides of the valve body shell to hold it. When gripped by the grippers, the valve body shell is prone to height displacement on the grippers, which affects the relative clamping height between the grippers and the valve body shell, impacting subsequent assembly processes. To improve the loading efficiency of the valve body shell and avoid height displacement of the valve body shell on the grippers during clamping, we propose a valve body shell loading device for valve body assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a valve body shell loading device for valve body assembly. During loading, a first driving component transports the valve body shell to the right side via a first placement plate for loading via a first placement plate. Once the first placement plate has finished loading, a second driving component transports the valve body shell to the right side via a second placement plate, and a lifting component aligns the second placement plate with the first placement plate, thus completing the loading process. This allows for uninterrupted continuous loading, improving production efficiency. Furthermore, the clamping component of this device clamps the front and rear sides of the valve body shell while simultaneously pressing against the top side, preventing height displacement of the valve body shell on the clamping jaws during clamping, which could affect subsequent assembly and solves the problems mentioned earlier.

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.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a valve body shell feeding device for valve body assembly, including a workbench 1.

On the two sets of slide rails 15, the front and rear sides of the sliding plate 13 are slidably connected to the two sets of slide rails 14. The top side of the sliding plate 10 and the top side of the sliding plate 13 are respectively placed on the first placement plate 8 and the second placement plate 9. The top of the first placement plate 8 and the second placement plate 9 are provided with several placement slots 34. The valve body shell 24 is placed on each of the several placement slots 34. The front and rear sides of the top of the worktable 1 are respectively equipped with a first drive assembly for driving the sliding plate 10 to slide on the slide rail 15 and a second drive assembly for driving the sliding plate 13 to slide on the slide rail 14. A lifting assembly is also installed at the bottom of the sliding plate 13.

[0028] When the device feeds the valve body shell 24, the mounting frame 7 is moved laterally by the lateral moving module 2, and the moving plate 27 is moved longitudinally by the longitudinal moving module 3 fixedly installed on the right side of the mounting frame 7. Then, the valve body shell 24 on the first placement plate 8 and the second placement plate 9 is clamped by the clamping assembly and transported to the next process. The sliding plate 10 is driven by the first driving assembly to slide on the slide rail 15, causing the first placement plate 8 to slide left and right. The sliding plate 13 is driven by the second driving assembly to slide on the slide rail 14, causing the second placement plate 9 to slide left and right. The valve body shell 24 is placed on the top of the first placement plate 8 and the second placement plate 9 by opening several placement slots 34. When feeding, the first placement plate 8 moves to the right first so that the valve body shell 24 on the first placement plate 8 is clamped and transported. After all are clamped, the second placement plate 9 moves to the right first, and the second placement plate 9 is lifted up by the lifting assembly to be flush with the first placement plate 8. Then the valve body shell 24 on the second placement plate 9 continues to be clamped and transported, forming continuous feeding.

[0029] The clamping assembly includes a sliding plate 29, two sets of sliding grooves 36 on the right side of the moving plate 27, two sets of sliders 35 fixedly connected to the left side of the sliding plate 29, the sliders 35 slidably connected to the sliding grooves 36, a cylinder 28 fixedly installed on the top of the moving plate 27, the output shaft end of the cylinder 28 fixedly connected to the top of the sliding plate 29, and a clamping mechanism installed on the right side of the sliding plate 29.

[0030] The clamping mechanism includes a gripper cylinder 30, which is fixedly installed on the right side of the sliding plate 29. Grippers 31 are installed on both the front and rear sides of the right side of the gripper cylinder 30. A fixing plate 32 is also fixedly connected to the right side of the sliding plate 29. A pressure plate 33 is installed on the fixing plate 32 by bolts. A mounting plate 25 is fixedly connected to the left side of the valve body shell 24. The front and rear sides of the mounting plate 25 abut against the two sets of grippers 31 respectively, and the top side of the mounting plate 25 abuts against the bottom side of the pressure plate 33.

[0031] The cylinder 28 pushes the sliding plate 39 to slide downward on the moving plate 27, so that the pressure plate 33, which is bolted to the fixed plate 22, abuts against the top side of the mounting plate 25, which is fixedly connected to the left side of the valve body shell 24. Then, the gripper cylinder 30 drives the two sets of grippers 31 to clamp the front and rear sides of the mounting plate 25, thus completing the clamping of the valve body shell 24. The pressure plate 33 prevents the valve body shell 24 from being displaced on the gripper 31 during clamping, thus avoiding subsequent assembly. The height of the pressure plate 33 can be adjusted on the fixed plate 22 by removing the bolts, so as to clamp valve body shells 24 of different sizes.

[0032] The first drive assembly includes a rodless cylinder 12, which is fixedly installed on the top front side of the worktable 1. A connecting plate 16 is installed on the front side of the rodless cylinder 12, and the top side of the connecting plate 16 is fixedly connected to the bottom side of the sliding plate 10.

[0033] The connecting plate 16 is driven to slide left and right by the rodless cylinder 2 12, thereby causing the sliding plate 10 to slide left and right on the slide rail 2 15.

[0034] The second drive assembly includes a rodless cylinder 11, which is fixedly installed on the top rear side of the worktable 1. A connecting plate 17 is installed on the rear side of the rodless cylinder 11, and the top side of the connecting plate 17 is fixedly connected to the bottom side of the sliding plate 13.

[0035] The rodless cylinder 11 drives the connecting plate 17 to slide left and right, thereby causing the sliding plate 13 to slide left and right on the slide rail 14.

[0036] The lifting assembly includes a cylinder 23. A fixing plate 19 is provided on both the front and rear sides of the bottom of the sliding plate 13. Two sets of fixing rods 20 are fixedly connected between the top side of the fixing plate 19 and the bottom side of the sliding plate 13. Fixing rods 21 are fixedly connected to the top left and right sides of the two sets of fixing plates 19. Lifting plates 18 are provided on both the left and right sides of the sliding plate 13. Mounting plates 22 are fixedly connected to the bottom left and right sides of the sliding plate 13. The top of the fixing rods 21 is fixedly connected to the bottom side of the mounting plate 22. The cylinder 23 is fixedly mounted on the bottom side of the mounting plate 22. The output shaft end of the cylinder 23 passes through the mounting plate 22 and is fixedly connected to the bottom side of the lifting plate 18. Limiting blocks 6 are fixedly connected to the front and rear sides of the top of the mounting plate 22.

[0037] The lifting plate 18 is lifted by the output shaft end of cylinder 23, which in turn lifts the second placement plate 9. Since cylinder 23 is fixedly installed on mounting plate 22, and mounting plate 22 is fixedly connected to fixed plate 19 by fixing rod 21, and fixed plate 19 is fixedly connected to sliding plate 13 by fixing rod 20, cylinder 23 does not disengage from sliding plate 13 when sliding plate 13 slides left and right, thus ensuring the stable lifting of lifting plate 18.

[0038] Two sets of insert rods 38 are fixedly connected to the top left and right sides of the sliding plate 10 and the top sides of the two sets of lifting plates 18. Two sets of insertion holes 37 are opened on the top left and right sides of the first placement plate 8 and the top left and right sides of the second placement plate 9. The insert rods 38 are inserted into the insertion holes 37. Through the cooperation of the insert rods 38 and the insertion holes 37, the first placement plate 8 and the second placement plate 9 are stably placed on the sliding plate 10 and the sliding plate 2 13.

[0039] Handles 5 are fixedly connected to the top left and right sides of the first placement plate 8 and the top left and right sides of the second placement plate 9, so that the first placement plate 8 and the second placement plate 9 can be quickly lifted through the handles 5.

[0040] A valve stem mounting groove 26 is provided on one side of the valve body housing 24, through which the valve stem is mounted.

[0041] Support legs 4 are fixedly connected to the four corners of the bottom of the workbench 1 to ensure the stability of the equipment during operation.

[0042] Working principle: When the device is feeding the valve body shell 24, the mounting frame 7 is moved laterally by the lateral moving module 2, and the moving plate 27 is moved longitudinally by the longitudinal moving module 3 fixedly installed on the right side of the mounting frame 7. Then, the sliding plate 29 is pushed down on the moving plate 27 by the cylinder 28, so that the pressure plate 33, which is bolted to the fixed plate 32, abuts against the top side of the mounting plate 25 fixedly connected to the left side of the valve body shell 24. Then, the gripper cylinder 30 drives the two sets of grippers 31 to clamp the front and rear sides of the mounting plate 25, thus completing the clamping of the valve body shell 24 on the first placement plate 8 and the second placement plate 9 and transporting it to the next process. During the clamping process, the pressure plate 33 presses against the top side of the valve body shell 24, so as to avoid the valve body shell 24 from being displaced on the gripper 31 and affecting subsequent assembly. The height of the pressure plate 33 can be adjusted on the fixed plate 32 by removing the bolts, so as to clamp valve body shells 24 of different sizes.

[0043] The connecting plate 16 is driven to slide left and right by the rodless cylinder 12, which in turn drives the sliding plate 10 to slide left and right on the slide rail 15, thereby driving the first placement plate 8 to slide left and right. The connecting plate 17 is driven to slide left and right by the rodless cylinder 11, which in turn drives the sliding plate 13 to slide left and right on the slide rail 14, thereby driving the second placement plate 9 to slide left and right. The valve body shell 24 is placed on the top of the first placement plate 8 and the second placement plate 9 by opening several placement slots 34. When feeding, the first placement plate 8 first moves to the right so that the valve body shell 24 on the first placement plate 8 is clamped and transported. After all are clamped, the second placement plate 9 first moves to the right and lifts the lifting plate 18 through the output shaft end of the cylinder 23, thereby lifting the second placement plate 9 and making the second placement plate 9 flush with the first placement plate 8, so that the valve body shell 24 on the second placement plate 9 continues to be clamped and transported, forming continuous feeding.
