Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1-8 , the present invention provides a technical solution: a milling device for valve processing with chip control and cooling functions, a placement groove 101 is installed at the center of the top of the operating table 1, and a support cover 2 is installed at the bottom of the operating table 1.

[0037] Specifically, a drive rod 201 is rotatably arranged inside the support cover 2, and one end of the drive rod 201 is connected to a lead screw mechanism 202. A moving block 203 is installed outside the lead screw mechanism 202, and two groups of lower connection seats 204 are symmetrically arranged outside the moving block 203. Two connection through grooves are formed on the operating table 1, and guide rods 205 are fixedly installed in the connection through grooves. A positioning block 206 is slidably connected to the guide rods 205. The guide rods 205 can limit the moving direction of the positioning block 206. The bottom of the positioning block 206 is connected to an upper connection seat 2061, and a connecting rod member 207 is movably installed between the upper connection seat 2061 and the lower connection seat 204. A positioning plate 208 is installed above the positioning block 206, and the positioning plate 208 is connected to a limiting plate 209 through a plurality of spring shafts 2081. A rubber anti-slip layer 2091 is adhesively fixed to the contact side of the limiting plate 209 with the valve body. By setting the rubber anti-slip layer 2091, while having a certain elasticity, it can also prevent the limiting plate 209 from damaging the valve body. A worm gear 3 is installed outside the drive rod 201, and the worm gear 3 meshes with a worm 301. Both ends of the worm 301 are connected to a rotating rod 302, and one rotating rod 302 is connected to a first drive motor 303. A first gear 304 is installed outside the rotating rod 302, and the first gear 304 meshes with a rack plate 305. The top of the rack plate 305 is connected to a lifting rod 306, and a moving through groove for cooperating with the lifting rod 306 is formed on the operating table 1. The lifting rod 306 is slidably connected to the inner side of the moving through groove. The two lifting rods 306 are connected through an isolation cover 4, and a rotary milling mechanism 5 is installed at the top inside the isolation cover 4. A sealing door is arranged on the front of the isolation cover 4.

[0038] Specifically, the rotary milling mechanism 5 includes a disc 501 which is rotatably connected to the top inside the isolation cover 4. A rack ring 502 is fixedly installed outside the disc 501, and the rack ring 502 meshes with a second gear 503. A second drive motor 504 for driving the second gear 503 to rotate is arranged at the top of the isolation cover 4. A third drive motor 505 is fixedly installed at the bottom of the disc 501, and the third drive motor 505 is connected to a milling head 506. The third drive motor 505 can drive the milling head 506 to rotate, so as to perform milling operations. When it is necessary to drive the milling head 506 to perform a circular movement to mill the end face through holes of the valve body at different positions, the second drive motor 504 is turned on. Under the action of the second drive motor 504, the second gear 503 drives the rack ring 502 and the disc 501 to rotate. Under the action of the rotation of the disc 501, the milling head 506 performs a circular movement.

[0039] Further explanation: Side plates 401 are symmetrically arranged on both outer sides of the isolation cover 4, and the side plates 401 are slidably connected to the vertical limiting slide bars 402 arranged on the top of the operating table 1. Through the above settings, the moving direction of the isolation cover 4 can be limited, thereby improving the stability of the isolation cover 4 during movement.

[0040] During use, place the valve body inside the placement groove 101. After placement, turn on the first drive motor 303. Under the action of the first drive motor 303, the rotating rod 302 rotates, thereby driving the first gear 304 and the worm 301 to rotate. Under the rotation of the worm 301, the worm wheel 3 and the drive rod 201 rotate, thereby driving the lead screw mechanism 202 to rotate through the drive rod 201. Under the rotation of the lead screw mechanism 202, the moving block 203 moves downward, thereby driving the positioning block 206 and the positioning plate 208 to move through the connecting rod member 207. The positioning plate 208 drives the limiting plate 209 to move synchronously through the spring shaft 2081, so that the two limiting plates 209 continuously approach each other. At the same time, under the rotation of the first gear 304, the rack plate 305 and the lifting rod 306 are driven to move, thereby driving the isolation cover 4 and the rotary milling mechanism 5 to continuously descend through the lifting rod 306. When the rotary milling mechanism 5 descends to the processing height, at this time, the two limiting plates 209 can also clamp and limit the valve body.

[0041] Specifically, a cooling and filtering mechanism 6 is installed on the outer top of the isolation cover 4, and the cooling and filtering mechanism 6 is connected to the air inlet cover 7 and the air outlet cover 701 arranged inside the isolation cover 4.

[0042] Specifically, the cooling and filtering mechanism 6 includes a filter box 601, and a filter plate 602 is arranged inside the filter box 601. A box door is opened on one side of the filter box 601 for facilitating the cleaning of impurities in the later stage. One side of the filter box 601 is connected to the air inlet cover 7 through a first delivery pipe 603, and the other side of the filter box 601 is connected to a cooling box 605 through a second delivery pipe 604. A cooling mechanism 606 is installed inside the cooling box 605, and the other side of the cooling box 605 is connected to a circulation fan 608 through a third delivery pipe 607. The circulation fan 608 is connected to the air outlet cover 701 through a fourth delivery pipe 609.

[0043] Further explanation, the cooling mechanism 606 includes a semiconductor refrigeration chip 6061, and the refrigerating surface of the semiconductor refrigeration chip 6061 is connected to a refrigerating plate 6062 arranged inside the cooling box 605. A number of groups of temperature guiding plates 6063 are installed on one side of the refrigerating plate 6062. The heating surface of the semiconductor refrigeration chip 6061 is connected to a heat conducting plate 6064 through heat conducting silicone, and the top of the heat conducting plate 6064 is connected to a heat sink 6065 through heat conducting silicone. The heat sink 6065 is connected to a cooling fan 6066. When it is necessary to cool the inside of the cooling box 605, the semiconductor refrigeration chip 6061 and the cooling fan 6066 are turned on. The semiconductor refrigeration chip 6061 starts to work. The semiconductor refrigeration chip 6061 transfers the low temperature to the inside of the cooling box 605 through the refrigerating plate 6062 and the temperature guiding plates 6063, thereby reducing the temperature inside the cooling box 605. The high temperature generated by the semiconductor refrigeration chip 6061 will be dispersed to the heat sink 6065 through the heat conducting plate 6064, and finally dispersed to the outside of the cooling box 605 through the cooling fan 6066.

[0044] During processing, the cooling and filtering mechanism 6 is turned on. Under the action of the circulating fan 608, the dust-containing gas inside the isolation cover 4 enters the inside of the filter box 601 through the air inlet cover 7 for filtering. The filtered gas enters the inside of the cooling box 605 through the second delivery pipe 604 for cooling. The cooled gas is discharged into the inside of the isolation cover 4 again through the third delivery pipe 607 and the fourth delivery pipe 609 through the air outlet cover 701 for circulating cooling and purification.
