Description

Technical Field

[0001] This utility model relates to the field of valve ball manufacturing technology, specifically to a valve ball milling device. Background Technology

[0002] The valve ball is the core opening and closing component (the ball) of a ball valve. It is rotated 90 degrees by the valve stem to cut off, distribute, or control the flow of fluid. During the manufacturing process, the valve ball usually requires precision machining such as milling to ensure sealing performance. Milling is a key process in valve ball manufacturing, directly affecting the performance and reliability of the valve.

[0003] For example, a valve ball spherical grinding device with application number CN202120015967.2 and authorization announcement date of 20220308 relates to the field of ball valve manufacturing. It includes a reciprocating rotary table mechanism, two sets of left-right symmetrical grinding mechanisms, and a clamping mechanism. The rotary table mechanism includes a drive component, a base, and a turntable, while the grinding mechanism includes a support plate, a grinding component, a rotating shaft, and a second motor. The clamping mechanism locks and drives the valve ball to rotate smoothly, while the grinding component of the grinding mechanism grinds the spherical surface of the valve ball under the drive of the second motor. The drive component drives the turntable to rotate reciprocally, and the turntable drives the grinding mechanism to swing around the central axis of the turntable to grind the valve ball, thereby achieving uniform grinding of the valve ball spherical surface and effectively improving the grinding efficiency of the valve ball spherical surface.

[0004] Traditional milling devices have difficulty quickly adapting to valve balls of different sizes. When changing workpieces, the fixture needs to be adjusted repeatedly, which is inefficient. Furthermore, uneven force during clamping can easily cause micro-displacement of the valve ball, affecting the milling accuracy. In addition, there is a lack of multi-directional synchronous adjustment mechanism. Therefore, it is urgent to design a valve ball milling device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A valve ball milling device includes a base plate and a clamping assembly. The clamping assembly is bolted to the outer walls of the top two sides of the base plate. The clamping assembly includes a mounting base. A mounting groove is formed on one outer wall of the top of the mounting base, and a clamping component is provided inside the mounting groove. Grooves are formed on both outer walls of the mounting base, and drive motors are bolted into the grooves. A mounting key shaft is mounted inside the mounting groove via bearings. The output ends of the two drive motors are fixedly connected to the two ends of the mounting key shaft via flat keys. Two lugs are integrally formed on both outer walls of the mounting base.

A piston cylinder is slidably inserted inside the guide cylinder, and the piston cylinder is threadedly connected to the adjusting screw. One end of the piston cylinder is slidably inserted into the cross-shaped cavity, and one end of the piston cylinder is in contact with the four magnetic blocks.

[0007] Furthermore, a mounting groove is provided on one side of the outer wall of the rotating block, and a rotary motor is installed inside the mounting groove by bolts. The output end of the rotary motor is fixedly connected to one end of the mounting key shaft by a flat key.

[0008] Furthermore, a milling assembly is bolted to one side of the outer wall of the top of the base plate. The milling assembly includes a mounting frame, and an adjusting motor is bolted to one side of the outer wall of the mounting frame. Two guide rods are bolted to the inside of the mounting frame.

[0009] Furthermore, a transmission screw is mounted inside the mounting bracket via bearings, and one end of the transmission screw is fixedly connected to the output end of the regulating motor via a coupling.

[0010] Furthermore, a sliding seat is slidably mounted on the outside of the mounting bracket, and the sliding seat is slidably connected to the two guide rods, and the sliding seat is threadedly connected to the transmission screw.

This structure can quickly adapt to valve balls of different sizes, and multi-directional synchronous positioning can be completed with a single adjustment.

It can adapt to the milling needs of various contours, such as spherical surfaces and inclined surfaces. Attached Figure Description

[0033] Working principle: The valve ball workpiece to be processed is placed at the center of the clamping member 8. Specifically, the valve ball is sleeved on the outside of the mounting cylinder 14. Then, the adjusting screw 18 is rotated, which drives the piston cylinder 22 to move axially inside the guide cylinder 17. One end of the piston cylinder 22 extends into the cross cavity 20 inside the mounting cylinder 14. When the piston cylinder 22 moves axially, its end pushes the magnetic blocks 21 located in the four openings of the cross cavity 20. Under the push of the piston cylinder 22, the four magnetic blocks 21 slide radially outward synchronously within the cross cavity 20. Due to the magnetic adsorption design of the contact surface between the magnetic blocks 21 and the piston cylinder 22, the synchronous movement of the four magnetic blocks 21 and the uniform distribution of the clamping force can be ensured. Furthermore, the radial movement of the magnetic blocks 21 drives the limiting plate 15 and the rubber block 16 to move radially synchronously. The four rubber blocks 16 contact and press the inner surface of the valve ball workpiece hole synchronously and evenly from four directions. In this process, the rubber blocks 16 provide flexible contact, which can effectively... The clamping mechanism not only prevents damage to the workpiece surface but also increases friction to prevent slippage. After the workpiece is clamped, the rotary motor 19 is started. The output of the rotary motor 19 directly drives the mounting key shaft 10 to rotate. Subsequently, the adjusting motor 24 drives the transmission screw 26 to rotate, causing the sliding seat 27 to move horizontally along the guide rod 25. At the same time, the translation cylinder 30 pushes the sliding frame 31 to move laterally, adjusting the lateral position of the milling cutter motor 32 and the milling cutter 33. This process can also be started by operating the lifting cylinder 34, which will slide the support frame 29 on the support rod 28, thereby achieving the vertical positioning of the milling cutter 33 and completing the precise tool setting in three-dimensional space. When the valve ball rotates, the milling cutter 33 cuts the spherical surface according to the preset path. The rotary motor 19 and the drive motor 7 work together to maintain a stable speed. After the spherical surface is machined, the drive motor 7 is started, and the mounting key shaft 10 drives the clamping part 8 to rotate 90° so that the end face of the valve ball faces the milling cutter 33. The milling cutter 33 is then fed again to complete the end face milling.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
