Description

Technical Field

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

[0002] A ball valve is a valve in which the valve stem drives the opening and closing parts to rotate around the axis of the ball valve. It is widely used in various facilities. The valve ball is an important component of the ball valve. During the production process, it is often necessary to use a fixture to fix the ball valve to facilitate subsequent processing.

[0003] In order to improve the stability of the valve ball during processing, the Chinese utility model patent with the publication number of "CN220197059U" discloses a ball valve cutting protection device, which relates to the field of ball valve cutting devices. The ball valve cutting protection device includes a bottom plate and a fixed cylinder for installing a ball valve body. The ball valve body is sleeved on the outer surface of the fixed cylinder. A cutting tool body for cutting the ball valve body is arranged on one side of the ball valve body. A threaded block for limiting the ball valve body is arranged on the outer surface of the fixed cylinder. A threaded groove is provided on the outer surface of one side of the fixed cylinder. The threaded block is threadedly connected to the inside of the threaded groove. The ball valve cutting protection device can fix the limit plate on the outer surface of one side of the fixed cylinder by threading the threaded block to the inside of the threaded groove. The ball valve body sleeved on the outer surface of the fixed cylinder can be limited. When the fixed cylinder drives the ball valve body to rotate, the limit plate can prevent the ball valve body from detaching from the outer surface of the fixed cylinder.

[0004] However, in actual use, we found that in the above scheme, the ball valve body is limited by inserting the ball valve body into the fixed cylinder, and then the limit plate is threadedly connected to the fixed cylinder. This method requires manual operation by the staff every time the limit is performed and the subsequent release of the limit is performed, which consumes a lot of labor of the staff. In addition, the ball valve body is prone to relative displacement with the fixed cylinder during high-speed rotation processing by only relying on the clamping of the limit plate, thereby affecting the actual processing quality. Therefore, in order to solve these problems, we need to consider designing a valve ball processing fixture. Utility Model Content

In view of the problem of use, a limit mechanism is set to limit the valve ball body. The entire limiting process and recovery process are relatively convenient and quick. The limit block is set to avoid relative displacement between the valve ball body and the limit column. At the same time, the valve ball body can be driven to rotate by a motor, which is convenient for multi-angle processing.

At the same time, the rotating disk can be driven to rotate by the motor, thereby driving the valve ball body to rotate, which is convenient for the staff to perform multi-angle processing on the valve ball body.

[0022] Among them, it also includes a limiting mechanism, which can limit the valve ball body 6. The limiting mechanism includes a limiting column 7 fixedly connected to the upper end of the rotating disk 5. The limiting column 7 cooperates with the circular through groove 15 to realize the pre-positioning of the valve ball body 6. A limiting groove 8 is horizontally provided on the right side of the limiting column 7. A limiting block 9 that can move left and right is arranged in the limiting groove 8. The limiting block 9 cooperates with the second rectangular through groove 16 to realize the stable limiting of the valve ball body 6, and effectively avoid the relative displacement of the valve ball body 6 and the limiting column 7 during subsequent processing. The limiting block 9 is slidably connected to the inner wall of the limiting groove 8, and the left side of the limiting block 9 is elastically connected to the left inner wall of the limiting groove 8 by two springs 10.
