Description

Technical Field

[0001] This application relates to the field of polishing equipment, and more specifically, to a water consumption control structure for a polishing machine. Background Technology

[0002] In the industrial manufacturing sector, polishing is a crucial step in improving product surface quality and is widely used in metal processing, ceramic manufacturing, glass processing, and many other industries. During polishing, to improve the polishing effect, reduce frictional heat, and remove processing debris, high-pressure water jets or polishing fluid are typically sprayed onto the contact area between the polishing wheel and the workpiece. Therefore, precisely controlling the amount of water used during polishing is of great importance for ensuring polishing quality, improving production efficiency, and conserving resources.

[0003] Currently, the water flow control methods commonly used in polishing machines on the market are relatively simple, mostly employing a fixed-flow liquid supply system. However, a fixed-flow liquid supply system cannot flexibly adjust the water flow according to different polishing process requirements, workpiece materials, and polishing stages. When performing fine polishing on some precision parts, a smaller water flow is required to avoid over-cooling or washing away the polishing compound; while when performing preliminary polishing on rough surfaces, a larger water flow is needed to quickly remove debris and dissipate heat. A fixed flow rate cannot meet these diverse needs, resulting in unstable polishing effects and affecting product quality. Therefore, this application proposes a water flow control structure for polishing machines. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of the prior art by providing a water consumption control structure for a polishing machine, thereby solving the problem of difficult flow control in the liquid supply system of existing polishing equipment.

[0006] To achieve the above objectives, this application provides the following technical solution: A water consumption control structure for a polishing machine includes a body with a valve chamber containing a horizontally movable valve core. A water inlet channel is located at the top of the body, and a water outlet channel is located at the bottom. The water inlet and outlet channels communicate with the valve chamber and are vertically aligned. A valve hole is vertically formed on the valve core. An end cap is located on one side of the body, and a valve stem is threaded through the end cap. One end of the valve stem extends into the valve chamber and is rotatably connected to the valve core. The other end of the valve stem is located outside the body and connected to a handle. The valve stem pushes and pulls the valve core to move horizontally, causing the valve hole to remain aligned or misaligned with the water inlet and outlet channels.

[0007] Furthermore, the top flange of the machine body is connected to a water injection connector, which is connected to a water injection channel, and the bottom flange of the machine body is connected to a water spray nozzle, which is connected to a water outlet channel.

[0008] Furthermore, a sealing gasket is provided between the end cap and the machine body, and a connecting screw is provided on the end cap, which is threaded into the machine body.

[0009] Furthermore, a ring seat is provided on one end face of the end cap facing the outside of the machine body, and a bushing is threaded on the ring seat, which is threadedly engaged with the valve stem.

[0010] Furthermore, a sealing sleeve is embedded in the end cover. The sealing sleeve has a T-shaped cylindrical structure and is fitted onto the valve stem. The end of the sealing sleeve with a larger cross-section is embedded between the bushing and the end cover.

[0011] Furthermore, the valve core has a vertically oriented assembly hole located on one side of the valve hole. Rubber sealing blocks are movably fitted at both the top and bottom of the assembly hole, and a spring is provided between a pair of rubber sealing blocks.

[0012] Furthermore, the rubber sealing block is frustoconical in shape, with a pair of rubber sealing blocks symmetrically distributed. The larger end of the rubber sealing block faces the assembly hole, and the cross-section of the larger end of the rubber sealing block is larger than the cross-section of the water injection channel and the water outlet channel.

[0013] Furthermore, a pair of first sealing rings are fitted on the valve core, and the pair of first sealing rings are distributed on both sides of the valve hole. A second sealing ring is also fitted on the valve core, and the second sealing ring is distributed on the side of the rubber sealing block away from the valve hole.

[0014] The beneficial effects of this application are as follows: By adjusting the alignment or misalignment of the valve core with the water injection and outlet channels, the flow rate of high-pressure water or polishing fluid can be controlled to meet the water requirements of different polishing processes, thereby improving polishing quality and efficiency. In addition, the valve core can be easily moved by turning the handle to control the flow of water or polishing fluid, making operation simple and convenient and reducing the labor intensity of operators.

[0015] By employing a first and second sealing ring to seal the valve core against the inner wall of the valve cavity, and by using rubber sealing blocks to seal the water injection and outlet channels, leakage of water or polishing fluid is effectively prevented, ensuring the reliability and stability of the structure. Simultaneously, the sealing sleeve achieves a seal between the valve stem and the end cap, further enhancing the overall sealing performance. Attached Figure Description

[0023] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-5 As shown, this utility model provides a water consumption control structure for a polishing machine, including a body 1. A water inlet connector 2 is connected to the top of the body 1 via a flange, and the water inlet connector 2 communicates with a water inlet channel 9 for receiving high-pressure water or polishing fluid. A water spray nozzle 3 is connected to the bottom of the body 1 via a flange, and the water spray nozzle 3 communicates with a water outlet channel 10.

[0025] Furthermore, the body 1 has a valve chamber 8 inside, and a valve core 11 capable of horizontal movement is installed in the valve chamber 8. A valve hole 12 is vertically opened on the valve core 11 for controlling the flow of water or polishing liquid. An assembly hole 15 is also opened on the valve core 11, located on one side of the valve hole 12. Rubber sealing blocks 14 are movably embedded at the top and bottom of the assembly hole 15. A spring 16 is set between a pair of rubber sealing blocks 14 to keep the pair of rubber sealing blocks 14 in an outward-protruding state. The rubber sealing blocks 14 are frustoconical in shape, and the pair of rubber sealing blocks 14 are symmetrically distributed, with the larger end facing the assembly hole 15. The cross-section of the larger end is larger than the cross-section of the water injection channel 9 and the water outlet channel 10, which can completely seal the water injection channel 9 and the water outlet channel 10.

[0026] Furthermore, in this embodiment, a pair of first sealing rings 13 are fitted onto the valve core 11, and the pair of first sealing rings 13 are distributed on both sides of the valve hole 12 to form a seal between the two sides of the valve hole 12 and the inner wall of the valve cavity 8. A second sealing ring 17 is also fitted onto the valve core 11, and the second sealing ring 17 is distributed on the side of the rubber sealing block 14 away from the valve hole 12, which, together with the first sealing rings 13, achieves a seal between the valve core 11 as a whole and the inner wall of the valve cavity 8.

[0027] Furthermore, in this embodiment, an end cap 4 is provided on one side of the body 1, and a sealing gasket 20 is provided between the end cap 4 and the body 1 to enhance the sealing performance. A connecting screw 21 is provided on the end cap 4, and the connecting screw 21 is threadedly engaged with the body 1 to fix the end cap 4 to the body 1. A valve stem 6 is provided on the end cap 4, one end of which extends into the valve cavity 8 and is rotatably connected to the valve core 11, and the other end is located outside the body 1 and is connected to a handle 7. By turning the handle 7, the valve core 11 can be pushed or pulled to move horizontally within the valve cavity 8. A ring seat 18 is provided on the end face of the end cap 4 facing the outside of the body 1, and a bushing 5 is threadedly fitted on the ring seat 18, and the bushing 5 is threadedly engaged with the valve stem 6. A sealing sleeve 19 is embedded in the end cap 4. The sealing sleeve 19 has a T-shaped cylindrical structure and is fitted onto the valve stem 6. The end of the sealing sleeve 19 with a larger cross-section is embedded between the bushing 5 and the end cap 4 to achieve a seal between the valve stem 6 and the end cap 4.

[0028] Furthermore, a connecting rod 24 is also connected to the machine body 1, and the connecting rod 24 is fixed on the shaft cylinder 23 on which the polishing wheel 22 is assembled. During the high-speed rotation of the polishing wheel 22, the machine body 1 remains relatively stationary to ensure the stable operation of the water volume control structure. The water nozzle 3 is bent towards the bottom of the polishing wheel 22 so as to accurately spray water or polishing liquid between the polishing wheel 22 and the workpiece to assist the polishing operation.

[0029] Working principle: This polishing machine has a water consumption control structure. During use... When it is necessary to stop the delivery of high-pressure water or polishing fluid, turn the handle 7 to push and pull the valve core 11 to move horizontally within the valve cavity 8, so that the valve hole 12 on the valve core 11 is completely misaligned with the water injection channel 9 and the water outlet channel 10. At the same time, under the action of the spring 16, a pair of rubber sealing blocks 14 are pushed toward the water injection channel 9 and the water outlet channel 10. Since the cross-section of the larger end face is larger than the cross-section of the water injection channel 9 and the water outlet channel 10, the water injection channel 9 and the water outlet channel 10 can be completely blocked, preventing the passage of high-pressure water or polishing fluid.

[0030] When the flow needs to be restored, turn handle 7 again to move valve core 11 horizontally, aligning or slightly misaligning valve orifice 12 with water injection channel 9 and water outlet channel 10. High-pressure water or polishing fluid can then flow smoothly through valve orifice 12, entering through water injection channel 9 and exiting through water outlet channel 10. Finally, it is sprayed through nozzle 3 onto the area between polishing wheel 22 and the workpiece, assisting in the polishing operation. Furthermore, by controlling the degree of misalignment between valve orifice 12 and water injection channel 9 and water outlet channel 10, the flow area of ​​water or polishing fluid can be adjusted, thereby controlling the flow rate.

[0031] When it is necessary to disassemble, repair, or assemble this water control structure, first remove the bushing 5 from the end cover 4, then remove the end cover 4 from the body 1. After that, the sealing sleeve 19, valve core 11, and other components can be removed in sequence for easy repair or replacement. After repair or replacement, reassemble in the reverse order.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
