Description

Technical Field

[0001] The present invention belongs to the technical field of ball valve processing, and in particular relates to a ball valve processing lathe and a processing method for a ball valve core. Background Art

[0002] A ball valve is a valve whose opening and closing member (ball) is driven by a valve stem and rotates around its axis. It can also be used for regulating and controlling fluids. The hard-sealed V-shaped ball valve, with its V-shaped core and carbide-clad metal seat, creates a strong shear force, making it particularly suitable for media containing fibers and tiny solid particles. Multi-way ball valves, on the other hand, can flexibly control the confluence, diversion, and flow direction of media in pipelines and can also close any channel while connecting the other two.

[0003] The valve core of the ball valve is a sphere with a transverse hole provided on the valve core, which can control the closing and opening of the ball valve by rotating the valve core. When processing the valve core, a metal cylindrical blank is usually turned into a spherical valve core blank, and 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 the ball valve core blank, the ball valve core blank and the cylindrical blank are usually directly turned off to separate the ball valve core blank from the cylindrical blank. However, after the ball valve core blank and the cylindrical blank are turned off, the ball valve core usually falls into a collection device, and the ball valve core may be damaged due to collision, thereby reducing the yield rate. When the fixed chuck fixes the cylindrical blank, the claws on the chuck may adhere to debris, affecting the fixation of the fixed chuck to the cylindrical blank, thereby reducing the processing accuracy.

[0017] A method for processing a ball valve core, using the above-mentioned ball valve processing lathe, comprises the following steps:

[0018] Before processing, the loading push block drives the cylindrical blank in the loading box to move upward, so that the cylindrical blank at the uppermost position can contact the moving magnetic block, the moving magnetic block moves and pushes the cylindrical blank to move between the clamping blocks, the rotating mounting plate moves to drive the clamping block to move close to the central axis of the mounting ring plate, the clamping block contacts and squeezes 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 claws of the rotating fixed chuck are in the open state, the rotating fixed chuck rotates, and the claws of the rotating fixed chuck contact with the cleaning block during the rotation;

[0019] After the cleaning of the jaws of the rotating fixed chuck is completed, the jaws of the rotating fixed chuck are moved to contact and fix the cylindrical blank, the clamping block is released from contact with the cylindrical blank, the mounting ring plate is moved and reset, and the machine tool body turns the cylindrical blank;

[0020] When the cylindrical blank is processed into a ball valve core blank and the ball valve core blank needs to be turned from the cylindrical blank, the mounting plate is rotated to interchange the position of the cleaning block with the position of the clamping block. The rotating mounting plate drives the cleaning block to move toward the center axis of the mounting ring plate, so that the distance between the cleaning block and the center axis of the mounting ring plate is greater than the radius of the ball valve core. The movement of the mounting ring plate drives the cleaning block close to the ball valve core, so that most of the ball valve core is located between the cleaning blocks. After the ball valve core is turned, it contacts the cleaning block. The moving magnetic block moves and contacts the ball valve core and drives the ball valve core, and drives the ball valve core to move into the blanking box, and the ball valve core is discharged from the blanking slot.

[0021] Compared with the prior art, the present invention provides a ball valve processing lathe and a processing method for a ball valve core, which have the following beneficial effects:

[0022] 1. The loading push block drives the cylindrical blank in the loading box to move upward, so that the cylindrical blank in the uppermost position can contact the moving magnetic block. The moving magnetic block moves and pushes the cylindrical blank to move between the clamping blocks. The rotating mounting plate moves to drive the clamping block to move toward the center axis of the mounting ring plate. The clamping block contacts and squeezes 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 claws of the rotating fixed chuck are in an open state. The rotating fixed chuck rotates, and the claws of the rotating fixed chuck contact with the cleaning block during the rotation process. The rotating fixed chuck is cleaned before the cylindrical blank is fixed to prevent debris attached to the claws of the rotating fixed chuck from affecting the fixation of the cylindrical blank, resulting in a decrease in the processing accuracy of the cylindrical blank.

[0023] 2. When the cylindrical blank is processed into a ball valve core blank and the ball valve core blank and the cylindrical blank need to be turned, the mounting plate is rotated to interchange the position of the cleaning block and the clamping block. The rotating mounting plate drives the cleaning block to move toward the center axis of the mounting ring plate so that the distance between the cleaning block and the center axis of the mounting ring plate is greater than the radius of the ball valve core. The movement of the mounting ring plate drives the cleaning block close to the ball valve core so that most of the ball valve core is located between the cleaning blocks. After the ball valve core is turned, it contacts the cleaning block. The moving magnetic block moves and contacts the ball valve core and drives the ball valve core, and drives the ball valve core to move into the blanking box, and the ball valve core is discharged from the blanking slot. The blank of the ball valve core that has been turned is supported to prevent the ball valve core blank from falling, which causes the ball valve core blank to be damaged due to collision and increases the defective rate.

[0024] 3. The ball valve core blank is moved to the unloading lifting plate. The unloading lifting plate moves downward due to the gravity of the ball valve core. The lifting spring is compressed. When the top surface of the unloading lifting plate is at the same height as the lowest end of the unloading notch, the ball valve core passes through the unloading notch and moves to the outside along the discharge guide rail. The staff collects and stores the ball valve core and automatically guides it out to facilitate collection and improve work efficiency.

[0042] The rotating mounting plate 402 can move and drive the clamping block 403 to move toward the central axis of the mounting ring plate 201. The rotating mounting plate 402 can rotate so that the position of the cleaning block 404 is interchanged with the position of the clamping block 403. The mounting ring plate 201 can drive the rotating mounting plate 402 to move.

[0043] The loading assembly 3 includes a movable magnetic block 301, a loading box 302, a loading push block 303, a discharge box 304, and a discharge notch 305. The movable magnetic block 301 is arranged on one side of the mounting ring plate 201, the loading box 302 is arranged below the movable magnetic block 301, the loading push block 303 is arranged in the loading box 302, and the discharge box 304 is arranged on one side of the loading box 302. A discharge notch 305 is opened on the side of the discharge box 304.

[0044] The movable magnetic block 301 can drive the ball valve core blank to move, and the loading push block 303 can move vertically. When the movable magnetic block 301 moves horizontally toward the mounting ring plate 201, the cylindrical blank on the top surface of the loading push block 303 can contact the movable magnetic block 301. When the movable magnetic block 301 moves horizontally toward the mounting ring plate 201, the cylindrical blank on the top surface of the loading push block 303 can no longer contact the movable magnetic block 301. The ball valve core falls into the discharge box 304 and can be discharged from the discharge notch 305.

[0045] When in use, before processing, the loading pushing block 303 drives the cylindrical blank in the loading box 302 to move upward so that the cylindrical blank in the uppermost position can contact the moving magnetic block 301, and the moving magnetic block 301 moves and pushes the cylindrical blank to move between the clamping blocks 403, and the rotating mounting plate 402 moves to drive the clamping block 403 to move close to the central axis of the mounting ring plate 201, and the clamping block 403 contacts and squeezes the cylindrical blank to fix the cylindrical blank.

The mounting ring plate 201 moves to drive the cleaning block 404 to move toward the center axis of the mounting ring plate 201. The ball valve core is close to the ball valve core, so that most of the ball valve core is located between the cleaning blocks 404.

[0063] Before processing, the loading push block 303 drives the cylindrical blank in the loading box 302 to move upward, so that the cylindrical blank at the uppermost position can contact the movable magnetic block 301, and the movable magnetic block 301 moves and pushes the cylindrical blank to move between the clamping blocks 403, and the rotating mounting plate 402 moves to drive the clamping block 403 to move close to the central axis of the mounting ring plate 201, and the clamping block 403 contacts and squeezes the cylindrical blank to fix the cylindrical blank, and the mounting ring plate 201 moves to drive the cylindrical blank close to the rotating fixed chuck 102, and the claws of the rotating fixed chuck 102 are in the open state, and the rotating fixed chuck 102 rotates, and the claws of the rotating fixed chuck 102 contact the cleaning block 404 during the rotation;

[0064] After the cleaning of the jaws of the rotating fixed chuck 102 is completed, the jaws of the rotating fixed chuck 102 move to contact and fix the cylindrical blank, the clamping block 403 releases the contact with the cylindrical blank, the mounting ring plate 201 moves and resets, and the machine tool body performs turning processing on the cylindrical blank;

[0065] When the cylindrical blank is processed into a ball valve core blank and the ball valve core blank needs to be turned from the cylindrical blank, the rotating mounting plate 402 is rotated to interchange the position of the cleaning block 404 with the position of the clamping block 403. The rotating mounting plate 402 drives the cleaning block 404 to move toward the direction of 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 core. The mounting ring plate 201 moves to drive the cleaning block 404 close to the ball valve core, so that most of the ball valve core is located between the cleaning blocks 404. After the ball valve core is turned, it contacts the cleaning block 404. The moving magnetic block 301 moves and contacts the ball valve core and drives the ball valve core, and drives the ball valve core to move into the discharge box 304, and the ball valve core is discharged from the discharge slot 305.
