[0002] As we all know, in the processing of hydraulic cylinder valves, the surface quality of the valve is crucial. The valve surface after traditional processing may have impurities such as oxide scale, oil stains, rust stains, and uneven surface roughness at the microscopic level. These problems will affect the sealing, wear resistance and corrosion resistance of the valve. The sandblasting device plays a key role in this process. It uses compressed air to spray abrasives onto the valve surface at high speed. During processing, it can effectively remove impurities and make the valve surface clean. At the same time, it can improve the microstructure of the valve surface and adjust the roughness, providing a good base for subsequent coating or other treatments, ensuring that the hydraulic cylinder valve can operate stably and reliably under complex working conditions and improving overall performance.

[0004] The existing surface sandblasting device for hydraulic cylinder valve processing and the use method thereof have the following disadvantages when used:

[0005] 1. When sandblasting the surface of the hydraulic cylinder valve, due to the lack of an adjustment structure installed on the continuous conveying equipment to perform all-round sandblasting on the hydraulic cylinder valve, the position of the sandblasting parts cannot be adjusted in all directions, which reduces the flexibility of processing the continuously conveying hydraulic cylinder valve;

[0028] A method for using a surface sandblasting device for processing a hydraulic cylinder valve comprises the following steps:

[0029] S1. All-round movement and feeding: First, energize and start the adjustment mechanism, then install the limit channel on the hydraulic cylinder valve continuous conveying equipment, and then adjust the electric gear to drive the guide gear ring to rotate the guide swivel, and the guide swivel will drive the displacement screw and the displacement guide rod to rotate, and then the displacement screw will drive the conveying block to move together, and the displacement servo motor will drive the displacement screw to rotate, and the displacement screw will drive the conveying block to move forward and backward along the displacement guide rod until the robot arm approaches the hydraulic cylinder valve required for sandblasting, and the suction pump will collect the sandblasting material in the base and send it to the finishing mechanism;

Sandblasting and magnetic chip grinding: First, the dressing mechanism is powered on and started, and then the feed pipe will deliver the sandblasting material to the sandblasting pump, and the sandblasting pump will pressurize the sandblasting material and spray it to the hydraulic cylinder valve. When water mist is generated during sandblasting, the exhaust fan will draw the water mist out along the drainage box through the filter plate. The water mist will liquefy after contacting the filter plate and drive the sandblasting material to drip into the adjustment mechanism for recovery with gravity. Then the finishing electric gear will drive the finishing gear ring to rotate the electromagnetic rod, and the electromagnetic rod will draw the drainage ring tube on the positioning plate when it rotates. Driven by the magnetic chips in the channel, the magnetic chips will move in a circle with the magnetic attraction of the electromagnetic rod, and then gradually generate centripetal force to grind the hydraulic cylinder valve. When the grinding produces debris and the number of magnetic chips increases, the magnetic chips will gradually approach the suction ring pipe with the centripetal force, and then the circulation pipe will pump the excess magnetic chips into the recovery tank through the suction ring pipe for recovery. When there are many magnetic chips in the recovery tank, the magnetic chips will be sent back to the drainage ring pipe from the suction ring pipe at the other end along the circulation pipe to grind the hydraulic cylinder valve.

[0031] In summary, the present invention has the following beneficial effects:

[0032] 1. By setting the adjustment mechanism, the limiting component can cooperate with the adjustment component, the displacement component and the feeding component. The limiting component can be installed on the hydraulic cylinder valve continuous conveying equipment. The adjustment component drives the displacement component to move in a circle along the limiting component, so that the left and right position of the displacement component can be changed. The displacement component can drive the feeding component to move forward and backward along the limiting component, so that the front and back position of the feeding component can be changed. The adjustment component cooperates with the displacement component, so that the feeding component can move in all directions along the limiting component, thereby improving the flexibility of the trimming mechanism in processing the hydraulic cylinder valve;

[0033] 2. By setting up a finishing mechanism, the positioning component can cooperate with the processing component, the recycling component and the finishing component.

The recycling component can perform magnetic chip grinding on the hydraulic cylinder valve, and can recycle the debris generated by magnetic chip grinding, and circulate the magnetic chips and debris to the hydraulic cylinder valve for cyclic grinding, thereby improving the flexibility of sandblasting the hydraulic cylinder valve.

The rod 244 cooperates with the finishing electric gear 242 to drive the finishing gear ring 243 to rotate, so that the finishing gear ring 243 can drive the electromagnetic rod 244 to rotate along the drainage annular pipe 241 when rotating, so that the electromagnetic rod 244 can stir the magnetic chips in the drainage annular pipe 241 when absorbing magnetic chips, and make the magnetic chips move in a circle around the drainage annular pipe 241, and gradually generate centripetal force with the movement of the electromagnetic rod 244, so that the hydraulic cylinder valve can be polished and polished after sandblasting, and at the same time, the extra debris generated by grinding can be moved to the suction ring pipe 231 for recovery after the centripetal force is generated.

[0060] Brief description of the use process: First, the dressing mechanism 2 is powered on and started, and then the feeding pipe 211 will convey the sandblasting material to the sandblasting pump 222, and the sandblasting pump 222 will pressurize the sandblasting material and spray it to the hydraulic cylinder valve. When water mist is generated during the sandblasting process, the exhaust fan 221 will extract the water mist along the drainage box 213 through the filter plate 223, and the water mist will liquefy after contacting the filter plate 223 and drive the sandblasting material to drip into the adjustment mechanism 1 for recovery along with gravity, and then the finishing electric gear 242 will drive the finishing gear ring 243 to rotate the electromagnetic rod 244, and the electromagnetic rod 244 will turn the drainage ring on the positioning plate 212 when it rotates. Driven by the magnetic chips in the pipe 241, the magnetic chips will move in a circle due to the magnetic attraction of the electromagnetic rod 244, and then gradually generate centripetal force to grind the hydraulic cylinder valve. When the grinding produces debris and the number of magnetic chips increases, the magnetic chips will gradually approach the suction ring pipe 231 due to the centripetal force, and then the circulation pipe 232 will pump the excess magnetic chips into the recovery tank 233 through the suction ring pipe 231 for recovery. When there are more magnetic chips in the recovery tank 233, the magnetic chips will be sent back to the drainage ring pipe 241 from the suction ring pipe 231 at the other end along the circulation pipe 232 to grind the hydraulic cylinder valve.

[0061] like Fig.11 As shown, the method for using the above-mentioned surface sandblasting device for processing a hydraulic cylinder valve comprises the following specific steps:

[0062] S1. All-round movement and feeding: First, the adjustment mechanism 1 is powered on and started, and then the limit channel 111 is installed on the hydraulic cylinder valve continuous conveying equipment, and then the electric gear 123 is adjusted to drive the guide gear ring 122 to rotate the guide swivel 121, and the guide swivel 121 will drive the displacement screw 132 and the displacement guide rod 133 to rotate, and then the displacement screw 132 will drive the conveying block 141 to move together, and the displacement servo motor 131 will drive the displacement screw 132 to rotate, and the displacement screw 132 will drive the conveying block 141 to move forward and backward along the displacement guide rod 133 until the mechanical arm 143 is close to the hydraulic cylinder valve required for sandblasting, and the suction pump 142 will collect the sandblasting material in the base 112 and send it to the finishing mechanism 2;

[0063] S2. Sandblasting and magnetic chip grinding: First, the dressing mechanism 2 is powered on and started, and then the feed pipe 211 will feed the sandblasting material to the sandblasting pump 222, and the sandblasting pump 222 will pressurize the sandblasting material and spray it to the hydraulic cylinder valve. When water mist is generated during sandblasting, the exhaust fan 221 will extract the water mist along the drainage box 213 through the filter plate 223, and the water mist will liquefy after contacting the filter plate 223 and drive the sandblasting material to drip into the adjustment mechanism 1 for recovery along with gravity, and then the finishing electric gear 242 will drive the finishing gear ring 243 to rotate the electromagnetic rod 244, and the electromagnetic rod 244 will guide the positioning plate 212 when it rotates. Driven by the magnetic chips in the flow ring pipe 241, the magnetic chips will move in a circle due to the magnetic attraction of the electromagnetic rod 244, and then gradually generate centripetal force to grind the hydraulic cylinder valve. When the grinding produces debris and the number of magnetic chips increases, the magnetic chips will gradually approach the suction ring pipe 231 due to the centripetal force, and then the circulation pipe 232 will pump the excess magnetic chips into the recovery tank 233 through the suction ring pipe 231 for recovery. When there are more magnetic chips in the recovery tank 233, the magnetic chips will be sent back to the drainage ring pipe 241 from the suction ring pipe 231 at the other end along the circulation pipe 232 to grind the hydraulic cylinder valve.
