The valve usually has three sets of end covers, two of which are used to connect to the external water inlet pipe and outlet pipe respectively, and the other set is used to install the valve cover directly. When processing the end cover, milling is usually required to make the end cover position smooth, and threaded holes are opened to facilitate installation.

A second driving motor 204 is provided at the bottom of the first rotating plate 202. The output end of the second driving motor 204 passes through the bottom wall of the first rotating plate 202 and is fixedly connected to the second rotating plate 205.

[0021] Those skilled in the art will appreciate that, by driving the first threaded rod 208 to rotate through the output end of the first servo motor 209, the two groups of lifting plates 210 are moved closer to or away from each other. When the two groups of lifting plates 210 are moved closer to each other, the three groups of clamping plates 215 connected thereto are driven to move closer to each other, clamping and fixing the outer surfaces of the three groups of end covers of the valve and wrapping the outer walls. When the two groups of lifting plates 210 are moved closer to each other, the three groups of clamping plates 215 connected thereto are driven to move away from each other.

When the two groups of first clamping blocks 214 are moved closer to each other, the clamping plates 215 are clamped and fixed, otherwise they are disassembled. The clamping plates 215 can be selected for installation according to the outer diameters of the three groups of end covers of the valve.

[0022] Example 3 Please refer to Figure 5 As shown, the closing mechanism 3 includes a mounting plate 301 fixedly connected to the outside of the top plate 207, the internal rotation of the mounting plate 301 is connected to a rotating rod 304, the outer wall of the rotating rod 304 is fixedly mounted with a driven gear 305, a third drive motor 302 is provided on the top of the mounting plate 301, the output end of the third drive motor 302 is fixedly connected to a drive gear 303 meshing with the driven gear 305, a first mounting frame 306 is welded to the bottom of the rotating rod 304, the internal rotation of the first mounting frame 306 is connected to an L-shaped piece 307, and a fourth drive motor 308 for driving the L-shaped piece 307 to rotate is mounted on the outer wall of the first mounting frame 306.

[0023] Please refer to Figure 6 As shown, the interior of the L-shaped part 307 is rotatably connected to the first screw rod 309, the outer surface of the first screw rod 309 is threadedly connected to the movable block 312, the movable block 312 is slidably connected to the first guide rod 310, the first guide rod 310 is welded to the interior of the L-shaped part 307, and a first stepper motor 311 is provided on the outside of the L-shaped part 307. The outer end of the first screw rod 309 is fixedly connected to the output end of the first stepper motor 311, and a second electric push rod 313 is installed on the outside of the movable block 312. The output end of the second electric push rod 313 is fixedly installed with a second double-headed electric cylinder 314, and the two output ends of the second double-headed electric cylinder 314 are fixedly connected to the second clamping block 315. The two groups of second clamping blocks 315 are used to clamp the closing part 316, and the top of the closing part 316 is provided with a second clamping groove 317 adapted to the second clamping block 315.

[0024] It will be understood by those skilled in the art that the output end of the fourth drive motor 308 can drive the L-shaped member 307 to rotate, so that the round rod of the L-shaped member 307 can be in a horizontal state, the frame on the L-shaped member 307 can be in a vertical state, and the closing member 316 is in a horizontal state. When the closing member 316 is in a horizontal state, the output end of the third drive motor 302 drives the driving gear 303 to rotate, causing the driven gear 305 and the rotating rod 304 to rotate as a whole, thereby driving the L-shaped member 307 to rotate with the center of the rotating rod 304 as the "center of the circle", thereby changing the direction of the closing member 316; When the closing member 316 is in a horizontal state and the frame on the L-shaped member 307 is in a vertical state, the output end of the first stepper motor 311 drives the first screw rod 309 to rotate, causing the movable block 312 to reciprocate up and down along the outer wall of the first guide rod 310, thereby driving the closing member 316 to reciprocate up and down, so that the center of the closing member 316 can be concentric with the center of the valve end cover of different inner diameters, and by controlling the output end of the second electric push rod 313 to extend, the closing member 316 is pushed forward, so that the closing member 316 enters the interior of the valve end; Since different valves have different inner diameters, the two output ends of the second double-headed electric cylinder 314 are controlled to extend or contract synchronously, thereby driving the two groups of second clamping blocks 315 to move away from or approach each other. When the two groups of second clamping blocks 315 approach each other, the closing piece 316 is clamped and fixed. Otherwise, the closing piece 316 is quickly disassembled. Closing pieces 316 with different outer diameters can be selected for installation according to the inner diameter of the valve.

[0026] Those skilled in the art can understand that, by driving the second screw rod 402 to rotate through the output end of the second stepper motor 408, the movable plate 404 is caused to reciprocate left and right along the outer wall of the second guide rod 403, thereby driving the processing box 406 to reciprocate left and right. When moving to the right, the sealing ring installed on the right side of the processing box 406 can be stuck in the sealing groove 217 opened on the two sets of fitting clamping plates 215; and the processing box 406 can be driven to rotate through the output end of the fifth drive motor 405, so that the processing box 406 can maintain a tilted state.

[0027] Example 5 Please refer to Figure 8 and Figure 9 As shown, the processing mechanism 5 includes a sixth drive motor 501 fixedly installed on the left side of the processing box 406, the output end of the sixth drive motor 501 is fixedly connected to the drive wheel 502, the internal rotation of the processing box 406 is connected to the rotating member 503, the outer wall of the rotating member 503 is fixedly connected to the driven wheel 504, the driving wheel 502 is connected to the driven wheel 504 through a belt, the internal rotation of the rotating member 503 is connected to the rotating frame 505, and the front side of the rotating member 503 is installed with a seventh drive motor 506 that drives the rotating frame 505 to rotate.

[0028] Please refer to Figure 10 As shown, the interior of the rotating frame 505 is fixedly connected to a third guide rod 508, and a group of first movable plates 510 and three groups of second movable plates 514 are slidably connected to the third guide rod 508. The first movable plates 510 and the second movable plates 514 are both threadedly connected to the third screw rod 507. The third screw rod 507 is rotatably connected to the rotating frame 505. The outer end of the third screw rod 507 is fixedly connected to the output end of the third stepping motor 509. The third stepping motor 509 is arranged at the bottom of the rotating frame 505. A third electric push rod 511 is installed on the outer side of the first movable plate 510. The output end of the third electric push rod 511 is connected to the second mounting frame 512. The second mounting frame 5 12 is internally rotatably connected to a milling cutter, which is driven by an eighth drive motor 513 on the outside of the second mounting frame 512. The second movable plate 514 is internally rotatably connected to a fourth electric push rod 515, wherein the output end of one group of the fourth electric push rods 515 is fixedly connected to the hot air blower 516, and the output ends of the other two groups of the fourth electric push rods 515 are installed with double-headed cylinders, and both output ends of the two groups of double-headed cylinders are installed with clamps for clamping drill bits and tapping heads, and an electric motor is provided on the outside of the second movable plate 514, and a driving gear is fixedly installed on the output end of the motor, and a passive gear meshing with the driving gear is installed on the outer wall of the fourth electric push rod 515.

[0029] Those skilled in the art will appreciate that the output end of the seventh driving motor 506 drives the rotating frame 505 to rotate, so that the rotating frame 505 can be kept in a vertical state or a horizontal state. When the rotating frame 505 is kept in a vertical state, when milling is required, the output end of the sixth driving motor 501 drives the driving wheel 502 to rotate, and under the action of the belt, the driven wheel 504 and the rotating member 503 rotate as a whole, driving the milling cutter to rotate with the center of the rotating member 503 as the "center of the circle", and under the action of the extension of the output end of the third electric push rod 511, the milling cutter is pushed close to the end cover of the valve, thereby realizing milling of the valve end cover position, and the milling cutter is driven to rotate by the output end of the eighth driving motor 513, thereby changing the angle of the milling cutter. In the present invention, there is a scenario in which this technical point can be used, and the output end of the third electric push rod 511 is extended, so that The milling cutter moves to the right side of the back of the valve end cover, and then the output end of the eighth drive motor 513 drives the milling cutter to rotate to an inclined state, so that the milling cutter contacts the back of the valve end cover, thereby achieving comprehensive milling of the back of the valve end cover; in addition, when milling the front of the valve end cover, it is only necessary to drive the third screw rod 507 to rotate through the output end of the third stepping motor 509, so that the milling cutter maintained in a horizontal state reciprocates along the outer wall of the third guide rod 508, so that the milling cutter maintained in a horizontal state can contact various points in the radial direction of the valve end cover, and finally, the milling cutter rotates with the center of the rotating member 503 as the "center of the circle", thereby achieving comprehensive milling of the front of the valve end cover; When the rotating frame 505 is kept in a vertical state, when drilling is required, the output end of the third stepping motor 509 drives the third screw rod 507 to rotate, so that the drill bit moves to the position to be drilled on the valve end cover along the vertical radial direction. Through the cooperation of the output end of the motor and the output end of the fourth electric push rod 515, the drill bit is rotated and pushed forward at the same time, thereby drilling a hole on the valve end cover. After that, the drill bit retracts, and the output end of the sixth drive motor 501 drives the drive wheel 502 to rotate. Under the action of the belt The driven wheel 504 and the rotating member 503 rotate as a whole, driving the drill bit to rotate with the center of the rotating member 503 as the "center of the circle". The center of the rotating member 503 and the center of the valve end cover are on the same straight line, so that the drill bit rotates to other positions to be drilled in turn, and the drilling operation is repeated, thereby achieving a plurality of groups of holes evenly penetrated on the outer side of the valve end cover. Then, similarly, the tapping head moves to the position corresponding to the hole and opens a thread in the hole, thereby achieving automated processing of the valve end cover; It is worth noting that the above descriptions are all descriptions of milling, drilling and tapping. During the processing of these processes, a coolant spraying device (not shown in the figure) is configured to spray the milling cutter, drill bit and tapping head, thereby improving the processing efficiency and the service life of the tool. However, in this case, the debris generated during the processing will adhere to the outer wall of the valve end cover due to the presence of the coolant. Therefore, the present invention is provided with a hot air blower 516. Similarly, under the action of the output end of the sixth drive motor 501, the hot air blower 516 rotates with the center of the rotating part 503 as the "center of the circle", and the outer wall of the valve end cover is fully purged. The coolant on the outer wall of the valve end cover can be quickly dried, and the debris can also be blown off without manual cleaning, thereby meeting the needs of the staff.

[0030] Example 6 Please refer to Figure 11 As shown, the tool storage mechanism 6 includes a frame 601 fixedly mounted on the top front side of the body 1, the frame 601 is internally rotatably connected to a fourth screw rod 602, the fourth screw rod 602 is threadedly connected to an L-shaped plate 605, the vertical plate of the L-shaped plate 605 is slidably mounted on a fourth guide rod 603, the fourth guide rod 603 is welded to the inside of the frame 601, the outer end of the fourth screw rod 602 is fixedly connected to the output end of the fourth stepper motor 604, the fourth stepper motor 604 is arranged on the outside of the frame 601, and a ninth drive motor 606 is installed at the bottom of the horizontal plate of the L-shaped plate 605, the output end of the ninth drive motor 606 is fixedly mounted with a storage disk 607, and the storage disk 607 is used to store drill bits and tapping heads.

[0031] Those skilled in the art will understand that, by driving the fourth screw rod 602 to rotate through the output end of the fourth stepper motor 604, the L-shaped plate 605 reciprocates along the outer wall of the fourth guide rod 603 toward the front or rear side, and when moving toward the front side, the storage tray 607 can be brought into the processing box 406 by opening the automatic door 407 on the front side of the processing box 406. In this way, the storage tray 607 storing the drill bits and tapping heads is set outside the processing box 406, in order to prevent the debris generated by the processing from falling onto the storage tray 607, and there is no need for the staff to clean the storage tray 607 later.

[0032] In order to clearly describe the working principle of the present invention, we use Figure 1 To illustrate the directional perspective, this directional perspective refers to the "front, back, left, right, up, down" that appears below, as follows: S1. Select and install the clamping plate 215 according to the outer diameter of the valve end cover. Use the robotic arm 101 to select and clamp multiple groups of clamping plates 215 placed externally, and transfer them to each group of connecting plates 212 in turn. By controlling the synchronous contraction of the two output ends of the first double-headed electric cylinder 213 inside each group of connecting plates 212, the two groups of first clamping blocks 214 are brought close to each other to fix the selected clamping plate 215. Secondly, the output end of the first servo motor 209 drives the first threaded rod 208 to rotate, so that the two groups of lifting plates 210 are brought close to each other, driving the three groups of clamping plates 215 connected to the two groups to be close to each other and fit together, clamping and fixing the outer surfaces of the three groups of end covers of the valve and wrapping the outer wall. This device is suitable for processing valve end covers of different outer diameters, and by controlling the extension or contraction of the output end of the first electric push rod 211, the position of the clamping plate 215 on the outer wall of the valve end cover is changed, so that the device is also suitable for processing valve end covers of different lengths, further improving the applicability of the present invention. S2. The valve has three sets of end covers. During processing, the end covers need to be milled and several sets of threaded holes are opened. The threaded holes opened on two sets of end covers are used to connect with the external water inlet pipe and outlet pipe respectively, while the threaded holes opened on the other set of end covers are used to install with the valve cover. The valve cover is provided with a valve stem. Next, we will take the set of valve end covers installed with the valve cover as an example to explain: The output end of the second driving motor 204 drives the second rotating plate 205 to rotate, so that the fixed valve rotates, and drives the valve end cover installed with the valve cover toward the processing box 406. The output end of the second stepping motor 408 drives the second screw rod 402 to rotate, so that the processing box 406 moves to the right, so that the sealing ring installed on the right side of the processing box 406 is stuck in the sealing groove 217 opened on the two sets of fitting clamping plates 215. Then, the closing member 316 is in a horizontal state, and the output end of the third driving motor 302 drives the driving gear 303 to rotate, so that the driven gear 305 and the rotating rod 304 rotate as a whole, thereby The L-shaped member 307 is driven to rotate with the center of the rotating rod 304 as the "center of the circle", thereby changing the direction of the closing member 316, so that the closing member 316 faces the valve end cover of the group connected to the water inlet pipe or the water outlet pipe. The output end of the first stepper motor 311 drives the first screw rod 309 to rotate, so that the center of the circle of the closing member 316 is concentric with the center of the circle of the valve end cover of the group connected to the water inlet pipe or the water outlet pipe, and the output end of the second electric push rod 313 is controlled to extend, so as to advance the closing member 316 and drive the closing member 316 into the interior of the valve end, so that the closing member 316 is located in the middle of the valve, thereby sealing the middle of the valve; Under the action of the processing mechanism 5, the milling cutter can fully mill the left and right sides of the valve end cover located inside the processing box 406, and form uniform threaded holes on its outer wall. During these processes, a coolant spraying device (not shown in the figure) is configured to spray the milling cutter, drill bit and tapping head, thereby improving the processing efficiency and the service life of the tool. However, in this case, the debris generated during the processing will adhere to the outer wall of the valve end cover due to the presence of the coolant. Therefore, the present invention is provided with a hot air blower 516. Similarly, under the action of the output end of the sixth drive motor 501, the hot air blower 516 rotates with the center of the rotating part 503 as the "center of the circle" to fully blow the outer wall of the valve end cover, which can The coolant on the outer wall of the valve end cover is quickly blown dry, and the debris can also be blown off without manual cleaning, which meets the needs of the staff. It is worth noting that during processing, debris will still splash into the interior of the valve. With the cooperation of the output end of the first drive motor 203 and the output end of the fifth drive motor 405, the processing box 406 and the fixed valve are kept in an inclined state. With the cooperation of the output end of the third stepping motor 509 and the output end of the fourth electric push rod 515, the hot air blower 516 enters the interior of the valve. The hot air blower 516 rotates inside the valve and is in a started state. Since the valve is in a tilted state, the coolant and debris inside the valve slide into the processing box 406 for collection, which further meets the needs of the staff. In addition, when processing the valve end cover connected to the external water inlet pipe and the water outlet pipe, the output end of the second drive motor 204 drives the second rotating plate 205 to rotate, so that the fixed valve rotates, and drives the valve end cover connected to the external water inlet pipe and the water outlet pipe toward the processing box 406. The output end of the second stepper motor 408 drives the second screw rod 402 to rotate, so that the processing box 406 moves to the right, so that the sealing ring installed on the right side of the processing box 406 is also stuck in the sealing groove 217 provided on the two sets of fitting clamping plates 215, so that the valve end cover connected to the external water inlet pipe and the water outlet pipe is also located inside the processing box 406. Then the closing member 316 is in a horizontal state, and the output end of the third drive motor 302 drives the driving gear 303 to rotate, so that the driven gear 3 05 and the rotating rod 304 rotate as a whole, thereby driving the L-shaped member 307 to rotate with the center of the rotating rod 304 as the "center of the circle", so that the closing member 316 faces the valve end cover of the group connected to the water inlet pipe or the water outlet pipe, and the output end of the first stepper motor 311 drives the first screw rod 309 to rotate, so that the center of the circle of the closing member 316 is concentric with the center of the circle of the valve end cover of the group connected to the water inlet pipe or the water outlet pipe, and by controlling the output end of the second electric push rod 313 to extend, the closing member 316 is pushed forward, driving the closing member 316 to enter the interior of the valve end. At this time, the closing member 316 is also located inside the processing box 406, and the outer side of the closing member 316 is flush with the outer side of the valve end cover to be processed. This operation prevents the debris and coolant generated by subsequent processing from entering the interior of the valve, and the above operation can be repeated.
