Description

Technical Field

[0001] This utility model relates to the field of valve seat manufacturing and processing technology, and in particular to a turning device for valve seat processing. Background Technology

[0002] The valve seat is the core component of a valve, usually installed inside the valve body, primarily serving a sealing and supporting function. It precisely matches the valve core, preventing media leakage and ensuring sealing performance; it also assists in controlling the flow of the media, regulating flow, and simultaneously withstanding the force exerted by the valve core and the pressure and temperature of the media. Valves are made from various materials; metals such as stainless steel are suitable for high-pressure and high-temperature conditions, while non-metals such as polytetrafluoroethylene (PTFE) are suitable for corrosive media. Their performance directly affects the reliability and service life of the valve.

[0003] During the machining process of valve seats, turning equipment is often required to machine key parts such as the sealing surface and inner hole of the valve seat to ensure dimensional accuracy and surface finish, so as to ensure the tightness of subsequent sealing fit.

[0004] A valve seat machining turning device disclosed in Chinese patent CN222755015U has a nozzle that can precisely spray into the interior of valve seats of different diameters, cooling the interior of the valve seat and flushing the cut debris into a waste bin, eliminating the need for secondary cleaning and saving time and effort. However, compared with existing technologies and comparative solutions, this valve seat machining turning device still has the following problems in actual use:

[0005] In this valve seat machining turning device, the power for the cleaning fluid injection comes from the cam driven by the rotating shaft to squeeze the air bladder. The cam speed is completely tied to the turning spindle speed. When the turning speed decreases, the cam squeezing frequency decreases, the air supply to the air bladder decreases, and the cleaning fluid injection volume is insufficient, which may lead to chip residue. When the turning speed increases, the injection frequency is too high, which easily causes waste of cleaning fluid. Moreover, during use, the cleaning fluid directly flushes the cut chips into the trash can, making it impossible to recycle the cleaning fluid and resulting in high production costs.

[0041] All electronic components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional, known device such as a computer. The electronic components, along with their associated control systems, power supply modules, circuits, and piping, can be provided by the manufacturer. Furthermore, all electronic components and control modules involved in this invention are existing technologies, fully capable of being implemented by those skilled in the art, and require no further explanation. This invention does not involve any improvement to the structure or usage of the electronic components.

[0042] The work process is as follows:

[0043] S1. Before use, add cutting fluid to the collection box 101;

[0044] S2. In use, the valve seat to be processed is placed between multiple fixed blocks 23. The third drive unit 223 is started. The third drive unit 223 drives the gear ring 222 to rotate through the worm gear 224. The gear ring 222 drives the second screw 225 to rotate through the gear 226. The second screw 225 drives the adjusting ring 227 to move towards the connecting plate 211, pushing the fixed block 23. The second slider 237 slides in the first slide groove 213, and the elastic element 238 contracts, so that the fixed block 23 clamps and fixes the valve seat to be processed.

[0045] S3. Slide the first slider 234 in the second slide groove 233, adjust the position of the adjusting nozzle 236 as needed, and then adjust the angle of the adjusting nozzle 236 as needed.

[0046] S4. Start the second drive unit 218. The second drive unit 218 drives the cutting tool 210 to rotate through the connecting shaft 219. Start the first drive unit 215. The first drive unit 215 drives the connecting seat 217 through the first screw 216. The connecting seat 217 drives the connecting shaft 219 through the second drive unit 218. The connecting shaft 219 drives the cutting tool 210, so that the cutting tool 210 moves along the axis of the first screw 216 during rotation, and performs turning machining on the hole or threaded hole on the valve seat.

[0047] S5. At the same time, start the connecting pump 106. The connecting pump 106 extracts the cutting fluid from the collection box 101 through the extraction pipe 107 and pumps it to the connecting pipe 235 through the diverter pipe 108 and the connector 109. Then it sprays it out from the regulating nozzle 236 to flush out the chips in the hole on the valve seat and cool the cutting tool 210.

[0048] S6. A valve is provided between the diverter pipe 108 and the connector 109. During use, the amount of cutting fluid sprayed from the regulating nozzle 236 can be controlled by the valve to avoid insufficient cutting fluid spray, resulting in chip residue, or excessive cutting fluid spray, resulting in cutting fluid waste.

[0049] S7. The ejected chips fall from the collecting hopper 102 into the collecting box 101 along with the cutting fluid. When the chips pass through the collecting frame 103, they are blocked by the separation net on the collecting frame 103, while the cutting fluid falls back into the collecting box 101 through the separation net on the collecting frame 103, forming a cycle, thereby reducing production costs.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
