Description

Technical Field

[0002] Hydraulic valves, as control valves in the hydraulic systems of engineering machinery, are components used to control the pressure, flow, and direction of liquid in hydraulic transmission. After the hydraulic valve body is formed, its surface and the hole system on its surface need to be further precision-machined. The structure of the hydraulic valve body is relatively complex, and the machining accuracy requirements are high. Its machining quality directly affects the overall performance of the hydraulic valve.

[0003] After the valve body is cast, it needs to be precision-machined and polished. Generally, the valve body is fixed on a machine tool, and a grinding tool is used to polish both ends of the valve body. However, a lot of debris is generated during the polishing process. Some of this debris remains in the grooves or on the surface of the two ends of the valve body. If it is not cleaned in time, the debris will scratch the surface of the precision-machined valve body, seriously affecting the quality of the product and reducing its precision. This is a shortcoming of the existing technology. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0017] like Figure 1-2 As shown, a valve body finishing device includes a base 1, on which a first bracket 2 and a second bracket 3 are provided. Grinding wheels are respectively installed on opposite sides of the first bracket 2 and the second bracket 3, and the grinding wheels are driven to rotate by a drive mechanism. A valve body 4 to be processed is provided between the first bracket 2 and the second bracket 3. Air nozzles 5 are respectively installed at the top of the first bracket 2 and the top of the second bracket 3.

[0018] This invention uses a grinding wheel to polish and finish the cast valve body. After finishing, an air jet nozzle is used to remove debris and powder from the surface and grooves of the valve body, which greatly improves the production efficiency and working environment of valve body finishing, reduces scratches on the surface of the valve body caused by debris and powder, and ensures the precision of valve body machining.

[0019] Furthermore, the first bracket 2 is mounted on the first slider (not shown in the figure), the first slider is slidably connected to the first slide rail 6, the first slide rail 6 is mounted on the base 1, and the base 1 is also provided with a first pneumatic cylinder (not shown in the figure) for driving the first slider to move horizontally; the second bracket 3 is mounted on the second slider (not shown in the figure), the second slider is slidably connected to the second slide rail 7, the second slide rail 7 is mounted on the base 1, and the base 1 is also provided with a second pneumatic cylinder (not shown in the figure) for driving the second slider to move horizontally. The first pneumatic cylinder drives the first slider to move, the first slider drives the first bracket 2 to move; the second pneumatic cylinder drives the second slider to move, the second slider drives the second bracket 3 to move.

[0020] Furthermore, a first motor (not shown in the figure) is mounted on the first bracket 2, and the output shaft of the first motor is connected to the first rotating base 11. A first grinding wheel 12 is mounted on the first rotating base 11. A second motor (not shown in the figure) is mounted on the second bracket 3, and the output shaft of the second motor is connected to the second rotating base 13. A second grinding wheel 14 is mounted on the second rotating base 13. The grinding wheel is the main tool for the precision machining of the valve body. This utility model adopts a double grinding wheel design, which not only speeds up the processing speed but also allows for simultaneous machining of two end faces, further improving production efficiency.

[0021] After the valve body is securely fixed, the first and second pneumatic cylinders are activated, causing the first support 2 and the second support 3 to move in opposite directions. This, in turn, drives the first grinding wheel 12 and the second grinding wheel 14 to move in opposite directions, thus performing precision machining on the valve body. The first grinding wheel 12 and the second grinding wheel 14 of this invention can be flexibly adjusted in position to accommodate valve bodies of different sizes and shapes.

[0022] Furthermore, an angle adjustment mechanism 8 is provided between the jet nozzle 5 and the first support 2, and correspondingly, an angle adjustment mechanism is also provided between the jet nozzle and the second support. The angle adjustment mechanism 8 includes a vertical support rod 81, a horizontal support rod 82, and a rotating plate 83. The lower end of the vertical support rod 81 is fixed to the first support 2, the upper end of the vertical support rod 81 is fixed to the horizontal support rod 82, the other end of the horizontal support rod 82 is hinged to the rotating plate 83, the upper end of the rotating plate 83 is fixed with the jet nozzle, the lower end of the rotating plate 83 is hinged to a telescopic assembly, and the other end of the telescopic assembly is hinged to the horizontal support plate. The jet nozzle not only effectively blows away debris generated during processing, keeping the working area clean, but its angle can also be flexibly adjusted through the angle adjustment mechanism. Specifically, by extending and retracting the telescopic assembly, the rotating plate 83 rotates around the horizontal support rod 82, ultimately achieving adjustment of the jet nozzle's angle and direction.

[0023] Furthermore, the telescopic assembly includes a first threaded rod 85, a threaded sleeve 86, and a second threaded rod 87. The first threaded rod 85 and the second threaded rod 87 are respectively screwed to both ends of the threaded sleeve 86, and the threads on the first threaded rod 85 and the second threaded rod 87 have opposite directions of rotation. The first threaded rod 85 is hinged to a first positioning rod 84, and the first positioning rod 84 is fixedly connected to a horizontal support rod 82. The second threaded rod 87 is hinged to a second positioning rod 88, and the second positioning rod 88 is fixedly connected to a rotating plate 83. By rotating the threaded sleeve 86, the relative position of the first threaded rod 85 and the second threaded rod 87 can be finely adjusted, thereby changing the angle of the air nozzle. This design is both practical and flexible, ensuring that debris is removed promptly and effectively during processing.

[0024] Furthermore, a valve body mounting seat 9 is provided between the first bracket 2 and the second bracket 3. The valve body mounting seat 9 is fixedly connected to the base 1. The upper surface of the valve body mounting seat 9 is an arc-shaped surface that matches the outer surface of the valve body, providing a stable support for the valve body. To ensure stability during processing, a clamping assembly 10 is provided above the valve body mounting seat. The clamping assembly 10 includes a third pneumatic cylinder 101 and a clamping rod 102. The third pneumatic cylinder 101 is vertically arranged and fixed to the base. The piston rod of the third pneumatic cylinder 101 is fixed to the clamping rod 102. The clamping assembly ensures that the valve body will not move or vibrate during processing, thereby guaranteeing processing accuracy. The valve body mounting seat 9 and the clamping assembly 10 cooperate to firmly fix the valve body, facilitating subsequent processing.
