Description

Technical Field

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

[0002] Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in pipelines. They can be closed tightly by rotating 90 degrees and using very small torque. Ball valves are widely used in long-line transportation and high-pressure transportation due to their good wear resistance, good sealing and long service life. In my country, ball valves are widely used in oil transportation, chemical production, papermaking, water and electricity and other industries. The valve body is an important component of the ball valve. The existing valve body needs to be polished with a polishing device during the production process to make its surface smooth and convenient for connection with the pipeline. Therefore, the demand for polishing devices for processing such ball valves is growing.

[0003] Most of the existing grinding devices for ball valve processing are automatic production line mechanical automatic grinding. Since the ball valve is an overall circular structure, it needs to be fixed through a through hole with an inner diameter during installation, so manual coordination and clamping are required during installation and fixation. The manual labor is large and the work efficiency is low. At present, conical blocks are usually used to squeeze and fix the two ends of the through hole. Although this method extends the conical surface of the conical block into the through hole and squeezes and fixes the two ends of the through hole through the conical surface, it improves the stability of the ball valve when fixing. However, the long-term use of the conical block and the squeezing of the two ends of the through hole can easily cause the conical surface to wear, which can easily lead to the concentricity deviation of the ball valve and the grinding device after fixation, thereby reducing the grinding accuracy of the ball valve surface. Summary of the invention

[0019] Step 2: At this time, the driving motor drives the worm to rotate clockwise, and the rotation of the worm drives the bidirectional lead screw to rotate through the meshing worm gear, and the rotation of the bidirectional lead screw causes the two threaded blocks to move relatively through the cooperation of the limit sleeve and the slide rod, and the movement of the threaded block drives the moving block to move through the first servo electric cylinder, and the movement of the moving block drives the rotating tube to move through the installation sleeve, so that the two rotating tubes move relatively to the inside of the valve body, and then the second servo electric cylinder piston rod is started to extend, and the second servo electric cylinder piston rod drives the telescopic rod to move, and the movement of the telescopic rod is stably moved by the guidance of the cross guide block, and drives the movable block to move, and the movement of the movable block drives the supporting swing rod to swing, and drives the reset block to move through the cooperation of the moving support and the reset rod;

[0020] Step three, the movement of the reset block squeezes the reset spring, and drives the arc surface clamping block to move through the support rod. The valve body is clamped and fixed at the center of the rotating tube through the synchronous support and clamping of multiple arc surface clamping blocks. At this time, the piston rod of the first servo electric cylinder is started to extend. The extension movement of the piston rod of the first servo electric cylinder drives the valve body to move up to the grinding position through the cooperation of the moving block, the mounting sleeve and the rotating tube. Then, the hand-tightening block is rotated clockwise according to the size of the valve body. The rotation of the hand-tightening block drives the adjusting screw to rotate through the cooperation of the bearing.

[0022] Step five, when grinding is completed, the piston rod of the first servo electric cylinder retracts, causing the valve body to move down into the positioning groove, and then the piston rod of the second servo electric cylinder retracts, causing the arc clamping block to disengage from the clamping positioning of the valve body. Finally, the driving motor drives the worm to rotate counterclockwise, causing the two rotating tubes to move away from the inside of the valve body in opposite directions. The first servo motor can then be started again to drive the cam to rotate one circle through the first rotating shaft, thereby realizing the unloading of the processed valve body and the loading of the valve body to be ground simultaneously.
