[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. After the valve body is placed in the support seat, the valve body is in a horizontal state. Then, the two positioning pieces are close to and positioned on the top outer surface of the valve body at the same time to initially stabilize the position of the valve body. When positioning the two ends of the valve body, the flip plate is in an open state to facilitate the docking installation of the side sealing plate and the end of the valve body. During the docking installation, the two side sealing plates are close to the end faces of the valve body at the same time to position the two end faces of the valve body and effectively fix the position of the valve body.

[0022] 3. By setting up a drilling mechanism, the rotating active gear drives the driven gear to rotate. Since the driven gear is meshed with the gear ring, the driven gear drives the limit cylinder and its drill rod to make a circular motion around the center of the active gear, and then the different positions of the valve body are processed.

When the two ends of the valve body are positioned, the flip plate 14 is in an open state, which is convenient for the docking installation of the side sealing plate 10 and the end of the valve body. During the docking installation, the two side sealing plates 10 are close to the end faces of the valve body at the same time, and the two end faces of the valve body are positioned to effectively fix the position of the valve body. Then, the rotation direction of the support seat 4 is changed by rotating the drive shaft 5, that is, the support seat 4 is rotated 90 degrees clockwise or counterclockwise.

When the electromagnet 16 is powered off, Under the elastic recovery of the second spring 28, the plug-in sealing plate 27 enters the ash storage barrel 17 at this time, and the ash storage barrel 17 is sealed and blocked again to prevent the waste chips from falling in the ash storage barrel 17 when the other end face of the valve body is turned over. When the ash storage barrel 17 is full of waste chips and the turning is completed, the electromagnet 16 continues to be energized to open the plug-in sealing plate 27, and the collection box is slidably placed on the processing table 2, wherein the collection box slides to the bottom of the processed waste chips, that is, below the open end of the ash storage barrel 17.

[0037] See also Figure 3 As shown, a processing groove 20 is provided on one side surface of the side sealing plate 10, and a through groove 19 is provided on the other side surface of the side sealing plate 10.

After the top outer surface of the valve body is initially positioned by the positioning piece, the two side sealing plates 10 simultaneously approach the two ends of the valve body to the middle, and the end face of the valve body enters through the through groove 19 until the end face of the valve body contacts the abutment plate 21, generating a thrust on the abutment plate 21, and squeezing the spring 22 under the push of the inner wall of the through groove 19. At this time, the abutment plate 21 slides in the through groove 19.

[0039] See also Figure 1 and Figure 5 As shown, a sliding hole and a screw hole are respectively provided on the bottom surface of each side sealing plate 10, a limiting rod 12 is slidingly arranged inside the sliding hole, and the internal thread of the screw hole is connected with a transmission screw 11 driven by a dual-axis motor embedded in the support seat 4, and the end of the limiting rod 12 is fixed to the surface of the support seat 4, and the corresponding transmission screw 11 is driven to rotate by the dual-axis motor, and the transmission screw 11 is threadedly connected to the corresponding side sealing plate 10, so that the two side sealing plates 10 slide along the limiting rod 12 and approach each other, and the two end surfaces of the valve body are positioned by the movement of the two side sealing plates 10.

[0040] See also Figure 3 and Figure 4 As shown, a receiving groove 24 is provided on the inner wall surface of the through groove 19, and a clamping part 25 is movably installed inside the receiving groove 24, and a synchronous cylinder 23 is installed on the inner side of the receiving groove 24 for pushing the clamping part 25 to move. The end of the inner wall surface of the clamping part 25 is provided with an arc slope 26 that contacts the end face of the valve body. When the two end faces of the valve body contact the abutting pressure plate 21, the synchronous cylinder 23 synchronously drives the clamping part 25 to slide in the receiving groove 24. At this time, the arc slope 26 on the clamping part 25 first contacts the end face of the valve body, so that the end face of the valve body applies pressure to the abutting pressure plate 21 again, and continues to compress the spring 1 22. The compression of the spring 1 22 is within its elastic deformation range, and the end face of the valve body is positioned by the clamping part 25, and then the flip plate 14 is rotated and closed, that is, the flip plate 14 is rotated to one side of the through groove 19. At this time, the ash storage cylinder 17 is in contact with the end face of the valve body, which is convenient for processing.

When the valve body is processed, the driven gear 34 is driven to rotate by the rotating driving gear 32. Since the driven gear 34 is meshed with the gear ring 33, the driven gear 34 drives the limiting cylinder 35 and its drill rod 7 to make a circular motion around the center of the driving gear 32, and then different positions of the valve body are processed. During processing, the built-in electric push rod pushes the installation rod 36 to slide in the limiting cylinder 35, and the drill rod 7 is pushed downward at this time, thereby realizing drilling processing.

[0043] When the present invention is in use, after the valve body is placed in the support seat 4, the valve body is in a horizontal state, and then the two positioning members simultaneously approach and position the top outer surface of the valve body to initially stabilize the position of the valve body. When positioning the two ends of the valve body, the flip plate 14 is in an open state, which is convenient for the butt-jointed installation of the side sealing plate 10 and the end of the valve body. During the butt-jointed installation, the two side sealing plates 10 simultaneously approach the end faces of the valve body to position the two end faces of the valve body, effectively fixing the position of the valve body. Then, the rotation direction of the support seat 4 is changed by rotating the drive shaft 5, that is, the support seat 4 is rotated 90 degrees clockwise or counterclockwise. At this time, the direction of the valve body changes from a horizontal state to a horizontal state. The valve body is then turned to the vertical position, and the processing position of the valve body is automatically adjusted, which is convenient for processing the two end faces of the valve body and improves the processing efficiency. When processing one end face of the valve body, the support seat 4 drives the valve body to flip, and then the driving shaft 13 drives the flip plate 14 to rotate and close. At this time, the ash storage barrel 17 is aligned with the processing position of the valve body end face, and the ash storage barrel 17 becomes vertical, and the plug-in sealing plate 27 in the ash storage barrel 17 is in an open state. The waste chips generated by the valve body hole processing enter the inner cavity of the ash storage barrel 17, which is convenient for the processing waste chips to fall. After the processing is completed, the plug-in sealing plate 27 blocks the inner cavity of the ash storage barrel 17 to avoid leakage of waste chips during processing.

[0044] When positioning the two ends of the valve body, the end face of the valve body enters through the through groove 19 until the end face of the valve body contacts the abutting pressure plate 21, generating a thrust on the abutting pressure plate 21, and squeezing the spring 12 under the push of the inner wall of the through groove 19. At this time, the abutting pressure plate 21 slides in the through groove 19, and then the synchronous cylinder 23 synchronously drives the clamping part 25 to slide in the accommodating groove 24. At this time, the arc slope 26 on the clamping part 25 first contacts the end face of the valve body, so that the end face of the valve body applies pressure to the abutting pressure plate 21 again, and continues to compress the spring 12, and the end face of the valve body is positioned through the clamping part 25, and then the flip plate 14 is rotated and closed, that is, the flip plate 14 is rotated to one side of the through groove 19. At this time, the ash storage cylinder 17 is in contact with the end face of the valve body, which is convenient for processing. The collection box slides to the bottom of the open end of the ash storage cylinder 17. When the plug-in sealing plate 27 is opened, the processing waste is collected by the collection box.

[0045] By setting up a drilling mechanism, the rotating driving gear 32 drives the driven gear 34 to rotate. Since the driven gear 34 is meshed with the ring gear 33, the driven gear 34 drives the limiting cylinder 35 and its drill rod 7 to make a circular motion around the center of the driving gear 32, and then the different positions of the valve body are processed. During the processing, the built-in electric push rod pushes the installation rod 36 to slide in the limiting cylinder 35, and the drill rod 7 is pushed downward at this time, so as to realize the drilling processing.
