Description

Technical Field

[0001] The utility model relates to the technical field of ball valve processing, in particular to a ball valve sphere surface processing device. Background Art

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc.

[0003] In order to ensure the sealing of the ball valve when it is opened or closed, the surface of the ball inside the ball valve must be smooth, so when producing and processing the ball, the surface of the ball needs to be polished. The current polishing method is to clamp and fix the ball from the outside of the ball with a fixture, and then manually polish the surface of the ball with a handheld grinder. In this process, the clamping position of the ball needs to be changed to ensure that the surface of the ball is completely polished. The processing efficiency is relatively low, and the labor intensity is relatively high. Therefore, the utility model proposes a ball valve ball surface processing device. Utility Model Content

[0021] like Figure 1-Figure 4 As shown, it relates to a ball valve ball surface processing equipment, including a base 1, a vertical plate 2 is fixed to one side of the upper surface of the base 1, a fixed sleeve 3 is fixed to one side of the top of the vertical plate 2, and the inner wall of the fixed sleeve 3 is rotatably connected to a round tube 4 through a bearing, and the surface of the round tube 4 away from one end of the vertical plate 2 is rotatably connected to two support rods 5, and the middle parts of the two support rods 5 are rotatably connected to a pull rod 6, and a first electric telescopic rod 7 driving the pull rod 6 to open is fixed to the top of the vertical plate 2 and away from the round tube 4. A rotating drive component for driving the round tube 4 to rotate is installed on the surface of the vertical plate 2 and below the round tube 4, and an L-shaped plate 14 is fixed to the side of the upper surface of the base 1 and close to the support rod 5, and a second electric telescopic rod 15 is fixedly connected to the top of the L-shaped plate 14, and a grinding component is installed at the bottom telescopic end of the second electric telescopic rod 15.

[0022] like Figure 1 and Figure 2 As shown, the telescopic end of the first electric telescopic rod 7 passes through the vertical plate 2 and extends to the inside of the circular tube 4. The telescopic end surface of the first electric telescopic rod 7 is rotatably connected with a connecting sleeve 8 through a bearing. Two connecting seats 9 are fixed on the surface of the connecting sleeve 8. Strip openings 10 are opened on the side walls of the circular tube 4 near the connecting seats 9. The connecting seats 9 pass through the strip openings 10 and are rotatably connected to the corresponding pull rod 6. The connecting seats 9 are slidably connected to the strip openings 10.

[0023] The first electric telescopic rod 7 pulls the connecting sleeve 8 to move toward the side of the vertical plate 2, and the connecting sleeve 8 pulls the pull rod 6 to open through the connecting seat 9, and the pull rod 6 pulls the support rod 5 to open, and the support rod 5 is used to support and fix the sphere from the inner wall of the sphere.

[0024] like Figure 1 As shown, one end of the support rod 5 away from the round tube 4 is bent, and a rubber sleeve is fixed on the surface of the bent end of the support rod 5 .

[0025] When the bent end of the support rod 5 is pressed against the inner wall of the sphere, the rubber sleeve can protect the inner wall of the sphere and increase the friction force, so that the support rod 5 can drive the sphere to rotate.

[0026] like Figure 1 and Figure 2 As shown, a driven gear 11 is fixedly connected to the outer wall of the circular tube 4 , and the rotation drive assembly includes a motor 12 fixed to the surface of the vertical plate 2 . The driving shaft of the motor 12 is fixedly connected to a driving gear 13 , and the driving gear 13 is meshed with the driven gear 11 .

[0027] By starting the motor 12, the driving gear 13 is driven to rotate, the driving gear 13 drives the driven gear 11 to rotate, the driven gear 11 then drives the round tube 4 to rotate in the fixed sleeve 3, the round tube 4 then drives the connecting seat 9 and the connecting sleeve 8 to rotate, and finally the pull rod 6 and the support rod 5 are rotated, and the support rod 5 then drives the ball to rotate.

[0031] Working principle: put the sphere to be polished on the surface of the two support rods 5, then adjust the position of the sphere while starting the second electric telescopic rod 15 to drive the arc-shaped polishing plate 19 to descend, so that the arc-shaped polishing plate 19 is just aligned with the sphere, then start the first electric telescopic rod 7 to shorten, and the telescopic end of the first electric telescopic rod 7 drives the connecting sleeve 8 to move to the side of the vertical plate 2, so that the connecting seat 9 on the surface of the connecting sleeve 8 is used to pull the pull rod 6 and the support rod 5 to open, and the sphere is supported and fixed by the support rod 5. After the sphere is fixed, start the motor 12 to drive the round tube 4 to rotate, and the round tube 4 then drives the support rod 5 and the sphere to rotate. At this time, the arc-shaped polishing plate 19 can polish the surface of the sphere.
