[0014] The following describes the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0015] See Figures 1 to 3The utility model provides a valve nut processing device, which is installed on a lathe 1. The lathe 1 is provided with a spindle box 2 and a slide 3. A chuck for loosening the valve nut is provided in the spindle box. The chuck comprises a first cylinder 4 and a first guide block 6 arranged on the front and rear sides of the slide 3. The first guide block 6 is elastically slidably equipped with a slide shaft 7. The piston rod of the first cylinder 4 and the slide shaft 7 are respectively connected to a drill bit 5 and a tap 8. The right end of the slide shaft 7 is provided with a vertical plate. The first guide block 6 is laterally slidably equipped with a slide shaft 7 connected to the first guide block 6. The guide rod of the vertical plate and the outer sleeve of the sliding shaft 7 are provided with a first elastic member connecting the vertical plate and the first guide block 6. The left end of the sliding shaft 7 is provided with a shaft shoulder against the first guide block 6. The first cylinder first drives the drill bit to drill the valve nut, and the sliding shaft pushed by the jacking assembly then drives the tap to thread the valve nut. A discharge assembly 9 for placing the nut into the chuck of the main spindle box 2 is provided in the middle of the top end of the main spindle box 2. The upper end of the lathe 1 is provided with a jacking assembly 10 for left-pushing the discharge assembly 9 and the sliding shaft 7. The discharge assembly pushes the valve nut into the chuck of the main spindle box through the jacking assembly. The chuck clamps the valve nut, and the slide moves back and forth. The drill bit driven by the first cylinder first drills the valve nut. After the tap is aligned with the valve nut, the jacking assembly pushes the sliding shaft to the left, and the sliding shaft drives the tap to thread the valve nut.

[0016] The unloading assembly 9 includes a bending plate 9.1 arranged at the top of the spindle box 2, and a second cylinder 9.2 is arranged downwardly at the top of the bending plate 9.1. The end of the piston rod of the second cylinder 9.2 is connected to a second guide block 9.3 with a guide hole therein. A through hole coaxial with the guide hole is provided at the left end of the bending plate 9.1, and a fixing plate 9.4 is provided at the upper end of the second guide block 9.3. A push rod 9.5 slidably fitted in the guide hole is provided at the fixing plate 9.4, and a second elastic member connecting the second guide block 9.3 and the fixing plate 9.4 is provided on the outer sleeve of the push rod 9.5. The vibration plate sorts the valve nuts, and other cylinders push the lowest valve nut to the right (and prevent subsequent valve nuts from falling). The valve nuts are transported to the guide hole of the second guide block through perforation (the guide hole can only accommodate one valve nut). The second cylinder drives the second guide block, push rod, and valve nut to descend. The valve nut descends to the chuck of the main spindle box, and the ejector assembly pushes the push rod to the left, and the push rod pushes the valve nut into the chuck. After the chuck clamps the valve nut, the second cylinder drives the second guide block and push rod to rise and reset, and the slide moves back and forth. The drill driven by the first cylinder first drills a hole in the valve nut. After the tap is aligned with the valve nut, the ejector assembly pushes the vertical plate to the left, and the vertical plate drives the tap to thread the valve nut through the sliding shaft.

[0017] See Figure 1 、 Figure 2The jacking assembly 10 includes a support block 10.1 mounted on the upper end of the lathe 1. A concave mounting plate 10.2 is mounted on the upper end of the support block 10.1, which can be adjusted left and right. A third cylinder 10.3 is positioned transversely on the mounting plate 10.2, which is used to push the left slide shaft 7 and push rod 9.5. The piston rod of the third cylinder pushes leftward, which in turn pushes the push rod and the slide shaft leftward.

[0018] The top of the mounting plate 10.2 is provided with an adjustment hole transversely, and the mounting plate 10.2 is locked to the support block 10.1 by a locking bolt passing through the adjustment hole. The left and right positions of the mounting block can be adjusted by the locking bolt, thereby adjusting different propulsion distances.

[0019] The piston rod of the third cylinder 10.3 is laterally connected to a slide bar that slides onto the mounting plate 10.2. A sensing element 12 is mounted on the end of the slide bar, and a sensor 11 is located on the front side of the left end of the mounting plate 10.2 to sense the sensing element 12. The slide bar, carrying the sensing element, moves left and right with the piston rod of the third cylinder, and the sensor precisely controls the propulsion distance.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
