Technical Field

[0001] This utility model relates to the field of deburring technology for hydraulic valve block processing, specifically to a deburring device for hydraulic valve block processing. Background Technology

[0002] A hydraulic valve block (also known as a hydraulic manifold) is a key component in a hydraulic system used to integrate and install various hydraulic control valves (such as directional valves, pressure valves, and flow valves) and to achieve complex oil circuit connections. Essentially, it is a metal block with precision-machined oil passages inside, and its standardized design enables a compact and modular arrangement of the hydraulic circuit.

[0003] The main body is a rectangular metal structure (commonly aluminum alloy or forged cast iron) 15, with an internal network of crisscrossing oil passages formed by drilling to connect the oil ports of various hydraulic valves. The surface is distributed with mounting holes, oil passages, bolt fixing holes, etc., and complex valve blocks can have hundreds of oil holes.

[0004] Chinese utility model patent announcement number: "CN214080631U" discloses a stainless steel valve plate double bevel deburring machine. This device can work simultaneously at multiple stations to polish, grind and deburr small stainless steel valve plate products. The equipment operates stably, with automatic loading and unloading, fully automated operation, high processing precision, and can effectively ensure product quality and improve work efficiency.

[0005] Although the above-mentioned device can automatically load and unload materials, it can only process one side during the processing. If other sides need to be processed, the workpiece side needs to be manually changed, which affects the workpiece processing efficiency. Utility Model Content

[0036] Clamping mechanism, used to drive the opposing connecting seats a72 to move closer to each other;

[0037] Angle adjustment mechanism is used to drive the clamping plate 9 to adjust its angle.

[0038] Specifically, a waste collection box 17 is fixedly connected to the lower inner wall of the washing box 1, and a filter box 18 is fixedly connected inside the waste collection box 17.

[0039] The burrs inside the openings on the surface of the hydraulic valve block are removed by using the impact force of the high-speed water jet through the special nozzle of the high-pressure water jet device 19.

[0040] The water containing impurities falls into the waste collection box 17 under its own weight, and the filter box 18 filters the impurities in the water.

[0041] Specifically, the clamping mechanism includes a cylinder 71, which is fixed to the inner wall of the front side of the connecting frame 6, and the connecting seat a72 is fixed to the telescopic end of the cylinder 71.

[0042] Four cylinders 71 are positioned in pairs, and the two opposing cylinders 71 push the two connecting seats a72, the two vertical plates 8, and the clamping plate 9 to move closer together to clamp the hydraulic valve block.

[0043] Specifically, the angle adjustment mechanism includes a screw 162, a servo motor 161, and a rack 164. A moving groove 15 is provided on the inner left side of the power box 10. The screw 162 is rotatably connected to the moving groove 15. A connecting seat b163 is slidably connected in the moving groove 15. The servo motor 161 is fixed to the upper side of the power box 10. The output shaft of the servo motor 161 extends into the moving groove 15 and is fixedly connected to the screw 162. The screw 162 meshes with the connecting seat b163. The rack 164 is fixed to the right side of the connecting seat b163. A gear 165 is rotatably connected in the power box 10 through symmetrical rotating shafts. The rack 164 meshes with the gear 165. The rear end of the rear rotating shaft extends out of the power box 10 and is fixedly connected to a clamping plate 9.

[0044] Servo motor 161 drives screw 162 to rotate. The rotation of screw 162 causes connecting seat b163 and rack 164 to move downward. The downward movement of rack 164 causes gear 165 and clamping plate 9 to adjust their angle. The angle adjustment of clamping plate 9 causes hydraulic valve block to adjust its angle, thereby adjusting the machined surface of hydraulic valve block.

[0045] Specifically, the circulation mechanism includes a water pump 141, which is fixed to the right side of the flushing tank 1. The discharge end of the water pump 141 is connected to the right side of the water tank 3 through a drain pipe 142, and the suction end of the water pump 141 is connected to the right side of the waste collection tank 17 through a suction pipe 143.

[0046] The high-pressure water jet device 19 removes burrs from the openings on the surface of the hydraulic valve block through a special nozzle. The water containing burrs falls into the waste collection box under its own weight.

[0047] Water pump 141 draws water from the bottom of waste collection box 17 through water pumping pipe 143 and discharges it back into water tank 3 through drain pipe 142, thus circulating the water and avoiding waste of water resources.

The extension and retraction ends of the spring rods 12 are fixedly connected to the placement plate 13.

[0049] An angle adjustment mechanism drives the clamping plate 9 to rotate, which in turn drives the hydraulic valve block to rotate, adjusting the machining surface of the hydraulic valve block. The rotation of the clamping plate 9 pushes the placement plate 13 and the spring rod 12 to move downward. After the hydraulic valve block flips over, the spring rod 12 pushes the placement plate 13 to move upward, placing the hydraulic valve block.

[0050] Working principle and usage process of this utility model:

[0051] In use, this utility model is as follows:

[0052] The hydraulic valve block is placed on the upper side of the placement plate 13. The four cylinders 71 are positioned in pairs. The two opposing cylinders 71 push the two connecting seats a72, the two vertical plates 8 and the clamping plate 9 to move closer to each other to clamp the hydraulic valve block. The burrs in the openings on the surface of the hydraulic valve block are removed by the impact force of the high-speed water flow through the special nozzle of the high-pressure water jet device 19. The water containing impurities falls into the waste collection box 17 under its own weight. The filter box 18 filters the impurities in the water.

[0053] Servo motor 161 drives screw 162 to rotate. The rotation of screw 162 causes connecting seat b163 and rack 164 to move downward. The downward movement of rack 164 causes gear 165 and clamping plate 9 to adjust their angle. The angle adjustment of clamping plate 9 causes hydraulic valve block to adjust its angle, thus adjusting the machining surface of hydraulic valve block. Water pump 141 draws water from the bottom of waste collection box 17 through water pumping pipe 143 and discharges it back into water tank 3 through drain pipe 142. This cycle is repeated to avoid water waste.
