Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to valve body processing equipment for producing solenoid valves. Background Art

[0002] During the casting or machining of the valve body, burrs, irregular textures or machining marks may appear on the surface of the valve body. These irregularities can be removed by grinding to ensure the flatness and smoothness of the valve body surface. At the same time, the inner wall of the valve body also needs to be polished. Grinding the inner wall can reduce the friction resistance of the fluid passing through the valve body, thereby improving the flow efficiency of the fluid. Burrs, tiny protrusions or other surface defects may appear on the inner wall. Grinding can remove these defects and ensure the smoothness of the inner wall. Grinding the inner wall can reduce the number of tiny cracks and flaws on the surface, thereby reducing the erosion of the corrosive medium on the valve body and extending the service life of the valve body.

[0003] The interior of the valve body is usually not a straight-through design, but has a certain structure and shape. In order to achieve different functions and meet the requirements of fluid control, the interior has curved, contracted or expanded channels to better control the speed and flow of the fluid. It also has an internal channel with a valve seat or other sealing structure. The valve can effectively prevent the flow of fluid when closed. This internal design greatly increases the difficulty of polishing the inside of the valve body. Manual polishing using sandpaper, grinding wheels or grinding heads is inefficient and consumes a lot of human resources. Even if special polishing equipment is used, such as internal hole grinders, polishing machines, etc., it is still impossible to perform comprehensive internal polishing, and the polishing effect cannot meet the use requirements. The waiting time through chemical polishing is long, which increases the processing time.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-9The present invention provides a technical solution: it includes an upper shell 1 and a lower shell 2, and multiple sets of positioning connection mechanisms 3 are connected to one side of the upper shell 1 and the lower shell 2, so that multiple solenoid valve bodies can be processed at the same time. At the same time, it is only suitable for three-way valves to improve efficiency. The positioning connection mechanism 3 located in the lower shell 2 is a fixed connection, and the positioning connection mechanism 3 located in the upper shell 1 is a sliding connection. A quick connector 4 is connected to one side of the positioning connection mechanism 3 away from each other, and a three-way pipe 5 is connected to the other end of the quick connector 4. The other two ends of the three-way pipe 5 are connected to the middle of the electric valve 6, which is used to control the two different substances in this application to enter the device through the three-way pipe 5. A connecting pipe 8 is connected to one side of the upper shell 1 and the lower shell 2, such as Figure 1 As shown, two connecting pipes 8 are connected with the corresponding three-way pipe 1 5, that is, they are located on one side of the upper shell 1 and the lower shell 2. The other end of the connecting pipe 8 is connected with a water inlet pipe 9. Because it is a conventional setting, the other end of the water inlet pipe 9 is generally connected to a water source and a driving member, so it is not repeated in the specification. A material receiving unit 10 is connected to one side of the lower shell 2, which is used to receive the used abrasive fluid and guide it into the separator 22, and filter and separate the cleaned water at the same time. One end of the three-way pipe 1 5 passes through the corresponding upper shell 1 and the lower shell 2, and is connected with the same three-way pipe 2 11. Through the three-way pipe 2 11, the three-way pipe 1 in the upper shell 1 and the lower shell 2 can be connected at the same time. 5, an abrasive fluid is injected to ensure that the grinding fluid used for grinding can enter the valve body synchronously to ensure the uniformity of grinding. The other end of the three-way pipe 11 is connected to a feeding barrel 12, and a piston ring frame 16 is slidably arranged inside the feeding barrel 12. The abrasive fluid in the feeding barrel 12 can be pushed into the three-way pipe 11 by the movement of the piston ring frame 16. A guide frame 17 is connected to one side of the piston ring frame 16. When the piston ring frame 16 moves in the direction of the upper feed electric push rod 13, the guide frame 17 can guide the internal abrasive fluid. The other side of the guide frame 17 is connected to an arc connecting rod 15. The other end of the arc connecting rod 15 extends through the feeding barrel 12 and is connected to a push plate 14. Figure 6 As shown, there are multiple groups of arc-shaped connecting rods 15. When the push plate 14 moves, it can simultaneously push the multiple groups of arc-shaped connecting rods 15 to move together, driving the piston ring frame 16 to move. A feeding electric push rod 13 is connected to one side of the push plate 14. The output end of the feeding electric push rod 13 passes through the push plate 14 and is connected to the feeding barrel 12, so that the push plate 14 can be driven to move by the contraction of the feeding electric push rod 13. A feeding mechanism 18 is connected inside the piston ring frame 16. When the piston ring frame 16 moves, the feeding mechanism 18 can well allow the abrasive with low fluidity to pass through the piston ring frame 16. A suction pipe 20 is connected to the side of the feeding barrel 12 away from the three-way pipe 11, as shown in FIG. Figure 6As shown, one end of the three-way pipe 11 and the material extraction pipe 20 close to each other is connected with a one-way valve to ensure the single flow direction of the fluid abrasive. The other end of the material extraction pipe 20 is connected with a storage bin 21, wherein the storage bin 21 stores fluid abrasive, and a material injection port is provided at the top. When the piston ring frame 16 pushes the abrasive fluid abrasive to the three-way pipe 11, the other side is negatively pressurized, so that the fluid abrasive in the storage bin 21 is extracted into the upper barrel 12 through the material extraction pipe 20. A separator 22 is connected to one side of the storage bin 21, wherein the separator is a device for removing metal from the fluid abrasive. Because it is an existing mature technology, it is not described in detail in the specification. like Figure 1-3 As shown, one side of the positioning and connecting mechanism 3 passes through the corresponding upper shell 1 and lower shell 2, and is connected with a valve body seat 7. The top of the positioning and connecting mechanism 3 located in the upper shell 1 is connected with a downward pressure electric push rod 301, and the other end of the downward pressure electric push rod 301 is fixedly set on the top of the inner wall of the upper shell 1. When the downward pressure electric push rod 301 pushes the positioning and connecting mechanism 3 located above to move downward, the valve body can be clamped by the valve body seat 7 for further fixation. Connecting frames 111 are connected on both sides of the upper shell 1 and the lower shell 2 to ensure the overall support effect.

[0021] like Fig. 9 As shown, the material receiving unit 10 includes a guide groove 101 fixedly arranged on one side of the lower shell body 2. When the fluid abrasive flows out through the port not connected to the valve body, it will be caught by the guide groove 101, flow along the guide groove 101, and flow to the feed port of the separator 22 through the recovery groove head 104, so as to separate the used fluid abrasive from the polished metal particles. A drain pipe 102 is connected to one side of the bottom end of the guide groove 101, and a water filter net 103 is connected to the bottom end of the inner side of the guide groove 101 corresponding to the drain pipe 102. When the cleaning water flows to the guide groove 101 through the valve body and flows to the water filter net 103, the water will flow to the drain pipe 102, and the remaining fluid abrasive will continue to flow and be recovered to the separator 22. A recovery groove head 104 is connected to one end of the guide groove 101, and one end of the recovery groove head 104 is located at the feed port at the top of the separator 22, so as to facilitate the recovery of the fluid abrasive.

[0022] like Figure 4As shown, the positioning connection mechanism 3 includes a square slot frame 31, which is a cube shell. A cylinder 32 is connected to one side of the square slot frame 31. The output end of the cylinder 32 extends into the square slot frame 31 and is connected to a movable orifice plate 33. The other side of the movable orifice plate 33 is connected to a valve head seat 34 and an infrared sensor 35. The cylinder 32 pushes the movable orifice plate 33 to move, so that the valve head seat 34 is tightly connected to the port of the valve body, wherein the infrared sensor 35 detects whether there is a valve head entering the square slot frame 331. And trigger the positioning unit 37, so as to connect the pipe rack connector 36 with the valve body to ensure the entry of fluid abrasive. The other end of the pipe rack connector 36 is connected to the quick connector 4. The three-way pipe 5 can be quickly connected to the pipe rack connector 36 through the quick connector 4. A plurality of groups of positioning units 37 are connected to one side of the inner wall of the square groove frame 31, and holes for installation are provided at the positions corresponding to the positioning units 37. The valve body enters the square groove frame 31 through the insertion holes. The positioning unit 37 can clamp and fix the valve body entering the square groove frame 31.

[0023] Reference Figure 5 As shown, the positioning unit 37 includes a guide groove 371 installed on one side of the inner wall of the square groove frame 31, a clamping block 373 is slidably arranged inside the guide groove 371, one side of the clamping block 373 is connected to a second cylinder 372, and the other end of the second cylinder 372 is fixedly arranged on one side of the inner wall of the square groove frame 31, and the second cylinder 372 pushes the clamping block 373 to move along the guide groove 371, thereby clamping the valve body.

[0024] Reference Figure 7-8 As shown, the feeding mechanism 18 includes a fixing frame 181 fixed to the inner side of the piston ring frame 16 and a driving motor 186 fixedly arranged on the piston ring frame 16. The fixing frames 181 are connected to the same hollow frame 182 at one end close to each other. A rotating shaft 183 is rotatably arranged on one side of the hollow frame 182. A gear ring 184 is connected to one end of the rotating shaft 183. The gear ring 184 is located in the hollow frame 182. The output end of the driving motor 186 passes through the piston ring frame 16 and is connected to an active timing wheel 187. A timing belt 188 is sleeved and connected between the active timing wheel 187 and the gear ring 184. When the driving motor 186 is rotated, a rotating shaft 183 is rotatably arranged on one side of the hollow frame 182. A gear ring 184 is connected to one end of the rotating shaft 183. The gear ring 184 is located in the hollow frame 182. When 186 is started, it drives the active timing wheel 187, and drives the gear ring 184 to rotate through the timing belt 188, thereby driving the rotating shaft 183 to rotate, wherein the guide roller 185 guides the timing belt 188 to ensure the meshing effect between the timing belt 188 and the gear ring 184, and a feed auger 19 is connected to one end of the rotating shaft 183. When the rotating shaft 183 rotates, the feed auger 19 rotates accordingly, thereby transporting the fluid abrasive entering the feed barrel 12 to the other side of the piston ring frame 16. The feed auger 19 is located on the inner side of the guide frame 17, and the guide frame 17 has a guiding effect on the feed auger 19.

[0025] Reference Figure 6As shown, a fitting groove 23 is provided on one side of the push plate 14 corresponding to the material extraction tube 20 , and when the push plate 14 moves toward the feed cylinder 12 , the fitting groove 23 allows the material extraction tube 20 to pass through.

[0026] The implementation principle of the embodiment of the present application is as follows: when the invention is in use, the connecting end of the valve body is inserted into the positioning connection mechanism 3 in the lower shell body 2 and fixed in position, and then the electric push rod 301 is pressed downward to push the positioning connection mechanism 3 located above to descend and connect with the other end of the valve body. Then the loading electric push rod 13 contracts and pushes the push plate 14, and the guide frame 17 is pushed to move through the arc connecting rod 15. The movement of the piston ring frame 16 is used to squeeze the fluid abrasive in the loading barrel 12 into the three-way pipe 11, so that it flows into the valve body through the three-way pipe 5, and the inner wall of the valve body is polished. The polished abrasive is discharged to the material receiving unit 10 through an unconnected port of the valve body to be recycled and reused. After polishing is completed, the direction of the three-way pipe 5 is changed through the solenoid valve 6, and the driving member is used to inject external water into the connecting pipe 8 through the water inlet pipe 9, so as to clean the inside of the polished three-way pipe 5.
