Description

Technical Field

[0001] The present invention belongs to the technical field of ball valve processing. Specifically, it particularly relates to a lathe for processing ball valves and a processing method for the valve cores of ball valves. Background Art

[0002] A ball valve is a valve in which the closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, for a hard-sealed V-type ball valve, there is a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, which is particularly suitable for media containing fibers, tiny solid particles, etc. A multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels.

[0003] The valve core of a ball valve is a sphere, and a transverse hole is provided on the valve core. The opening and closing of the ball valve can be controlled by the rotation of the valve core. During the processing of the valve core, a metal cylindrical blank is usually turned into a spherical valve core blank, and then the spherical valve core blank is drilled and polished to complete the processing and manufacturing of the ball valve core. In the existing valve core processing process, when the cylindrical blank is processed into a ball valve core blank, the ball valve core blank is usually directly cut off from the cylindrical blank to separate the ball valve core blank from the cylindrical blank. However, after the ball valve core blank is cut off from the cylindrical blank, the ball valve core usually falls into the collection device, and the ball valve core blank may be damaged due to bumping, reducing the yield rate. When the fixed chuck fixes the cylindrical blank, debris may adhere to the jaws on the chuck, affecting the fixation of the cylindrical blank by the fixed chuck, thereby reducing the processing accuracy.

[0013] A processing method for a ball valve spool, using the above-mentioned ball valve processing lathe, includes the following steps; Before processing, the feeding push block drives the cylindrical blank in the feeding box to move upward, so that the cylindrical blank at the uppermost position can contact the moving magnet block. The moving magnet block moves and pushes the cylindrical blank to move between the clamping blocks. The rotating mounting plate moves to drive the clamping blocks to move towards the central axis direction of the mounting ring plate.

The jaws of the rotating fixed chuck are in an open state. The rotating fixed chuck rotates, and the jaws of the rotating fixed chuck contact the cleaning block during the rotation; After the jaws of the rotating fixed chuck are cleaned, the jaws of the rotating fixed chuck move to contact and fix the cylindrical blank. The clamping blocks are disengaged from the contact with the cylindrical blank. The mounting ring plate moves back to its original position. The machine body performs turning processing on the cylindrical blank; When the cylindrical blank is processed into a ball valve spool blank and it is necessary to cut off the ball valve spool blank from the cylindrical blank, the rotating mounting plate rotates to swap the positions of the cleaning block and the clamping blocks. The rotating mounting plate moves to drive the cleaning block to move towards the central axis direction of the mounting ring plate, so that the distance between the cleaning block and the central axis of the mounting ring plate is greater than the radius of the ball valve spool. The mounting ring plate moves to drive the cleaning block close to the ball valve spool, so that most of the ball valve spool is located between the cleaning blocks. After the ball valve spool is cut off, it contacts the cleaning block. The moving magnet block moves to contact the ball valve spool and drives the ball valve spool, and drives the ball valve spool to move into the discharging box. The ball valve spool is discharged from the discharging slot opening.

[0014] Compared with the prior art, the present invention provides a ball valve processing lathe and a processing method for a ball valve spool, having the following beneficial effects: 1. The feeding push block drives the cylindrical blank in the feeding box to move upward, so that the cylindrical blank at the uppermost position can contact the moving magnet block. The moving magnet block moves and pushes the cylindrical blank to move between the clamping blocks. The rotating mounting plate moves to drive the clamping blocks to move towards the central axis direction of the mounting ring plate. The clamping blocks contact and squeeze the cylindrical blank to fix the cylindrical blank. The mounting ring plate moves to drive the cylindrical blank close to the rotating fixed chuck. The jaws of the rotating fixed chuck are in an open state. The rotating fixed chuck rotates, and the jaws of the rotating fixed chuck contact the cleaning block during the rotation; Before the cylindrical blank is fixed, the rotating fixed chuck is cleaned to prevent the debris attached to the jaws of the rotating fixed chuck from affecting the fixing of the cylindrical blank and causing the processing accuracy of the cylindrical blank to decrease.

[0015] 2. When the cylindrical blank is processed into the blank of the ball valve spool and it is necessary to cut off the ball valve spool blank from the cylindrical blank, rotate the mounting plate so that the positions of the cleaning block and the clamping block are interchanged. Rotate and move the mounting plate to drive the cleaning block to move towards the central axis direction of the mounting ring plate, so that the distance between the cleaning block and the central axis of the mounting ring plate is greater than the radius of the ball valve spool. Move the mounting ring plate to drive the cleaning block close to the ball valve spool, so that most of the ball valve spool is located between the cleaning blocks. After the ball valve spool is cut off, it contacts the cleaning block. Move the magnetic block to move and contact the ball valve spool and drive the ball valve spool, and drive the ball valve spool to move into the blanking box, and the ball valve spool is discharged from the blanking slot. Support the blank of the cut-off ball valve spool to prevent the blank of the ball valve spool from falling, resulting in damage to the blank of the ball valve spool due to bumping and increasing the defective rate.

[0016] 3. The blank of the ball valve spool moves onto the blanking lifting plate. The blanking lifting plate moves downward under the gravity of the ball valve spool, and the lifting spring is compressed. When the top surface of the blanking lifting plate is at the same height as the lowest end of the blanking slot, the ball valve spool passes through the blanking slot and moves along the discharge guide rail to the outside. The staff collects and stores the ball valve spool, automatically exports the ball valve spool, which is convenient for collection and improves work efficiency.

The top surfaces of the cleaning block 404, the feeding push block 303, and the discharging lifting plate 310 are all arc-shaped surfaces, and the side surface of the moving magnet block 301 is an arc-shaped surface.

[0032] This embodiment also discloses a processing method for a ball valve spool, which uses the above-mentioned ball valve processing lathe and includes the following steps; Before processing, the feeding push block 303 drives the cylindrical blank in the feeding box 302 to move upward, so that the cylindrical blank at the uppermost position can contact the moving magnet block 301. The moving magnet block 301 moves and pushes the cylindrical blank to move between the clamping blocks 403. The rotating mounting plate 402 moves to drive the clamping blocks 403 to move towards the direction close to the central axis of the mounting ring plate 201. The clamping blocks 403 contact and squeeze the cylindrical blank to fix the cylindrical blank. The mounting ring plate 201 moves to drive the cylindrical blank to approach the rotating fixed chuck 102. The jaws of the rotating fixed chuck 102 are in an open state. The rotating fixed chuck 102 rotates, and the jaws of the rotating fixed chuck 102 contact the cleaning block 404 during the rotation process; After the jaws of the rotating fixed chuck 102 are cleaned, the jaws of the rotating fixed chuck 102 move to contact and fix the cylindrical blank. The clamping blocks 403 are disengaged from the contact with the cylindrical blank. The mounting ring plate 201 moves back to its original position, and the machine tool body performs turning processing on the cylindrical blank; When the cylindrical blank is processed into a ball valve spool blank and it is necessary to cut off the ball valve spool blank from the cylindrical blank, the rotating mounting plate 402 rotates to swap the positions of the cleaning block 404 and the clamping blocks 403. The rotating mounting plate 402 moves to drive the cleaning block 404 to move towards the direction close to the central axis of the mounting ring plate 201, so that the distance between the cleaning block 404 and the central axis of the mounting ring plate 201 is greater than the radius of the ball valve spool. The mounting ring plate 201 moves to drive the cleaning block 404 to approach the ball valve spool, so that most of the ball valve spool is located between the cleaning blocks 404. After the ball valve spool is cut off, it contacts the cleaning block 404. The moving magnet block 301 moves to contact the ball valve spool and drives the ball valve spool, and drives the ball valve spool to move into the discharging box 304. The ball valve spool is discharged from the discharging slot 305.
