Description

Technical Field

[0001] The invention relates to the technical field of grinding machines, in particular to a grinding machine with circulated grinding fluid. Background Art

[0002] Grinding machines are key equipment used for precision grinding in the machining industry. They achieve surface finishing through high-speed relative motion between the grinding wheel and the workpiece. They are widely used in industries requiring extremely high part precision, such as automotive manufacturing, aerospace, and mold processing. During the grinding process, the intense friction between the grinding wheel and the workpiece generates significant heat and metal debris. If not promptly addressed, this can cause burns on the workpiece surface, clog the grinding wheel, reduce machining accuracy, and even damage both the workpiece and the grinding wheel.

[0003] Grinding fluid is an important auxiliary medium in grinding machine processing. Its core functions include: reducing the temperature of the grinding zone through heat exchange to prevent the workpiece from being deformed by heat and affecting the accuracy; flushing away the grinding chips to prevent the grinding chips from being embedded in the grinding wheel surface and causing scratches on the workpiece; forming a lubricating film between the workpiece and the grinding wheel to reduce friction and wear and extend the service life of the grinding wheel.

[0004] For example, the Chinese utility model patent application number 202020900749.2 discloses an easy-to-operate grinder equipped with a transparent protective structure and a transparent dustproof structure, which can effectively prevent flying debris from injuring people, and can also facilitate people to watch the grinding process, which is beneficial to people's use. It can also effectively prevent dust from falling on the surface of the control computer, which can ensure the hygiene of the control computer surface and the sensitivity of the control buttons on the control computer, ensure the safety of the staff, and bring better use prospects. However, the device still has certain defects; During the processing of metal parts, it is necessary to spray polishing fluid on the workpiece and the polishing head, which is inconvenient to collect and reuse the polishing fluid. The metal ions in the grinding chips will increase the heavy metal content of the wastewater, which is not conducive to the discharge of wastewater and causes waste of water resources.

[0005] Therefore, we propose a grinding machine in which the grinding fluid can be recycled in order to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a grinding machine with recyclable polishing fluid, so as to solve the problem raised in the above background technology that in the process of processing metal parts in the current market, it is necessary to spray polishing fluid on the workpiece and the polishing head, which is inconvenient to collect and reuse the polishing fluid. The metal ions in the grinding chips will increase the heavy metal content of the wastewater, which is not conducive to the discharge of wastewater and causes waste of water resources.

[0024] Preferably, a nozzle is installed at the end of the water outlet pipe, the nozzle is located on the side of the grinding assembly, and the water outlet pipe is connected to the gantry through a limiting assembly, and the water outlet pipe is designed to be a retractable fixed structure.

[0025] With the above structural design, the nozzle at the end of the water outlet pipe sprays polishing liquid onto the polishing component and the workpiece, the limit component fixes the position of the water outlet pipe, and the retractable shaping structure adapts to the movement of the polishing component to ensure accurate spraying.

[0026] Compared with the prior art, the present invention has the following beneficial effects: the grinding machine in which the grinding fluid can be recycled: 1. Polishing fluid recycling, energy conservation, environmental protection and cost reduction: The polishing fluid is collected by the guide trough of the processing table and sent to the first filter box through the first connecting pipe.

[0033] Working principle: When using the grinding machine with recyclable grinding fluid, first, place the workpiece to be processed on the processing table 2 above the workbench 1, start the servo motor 6 on the left side of the gantry 4, which drives the ball screw 5 to rotate through the output shaft, and the movable block 7 slides along the slide groove 11 through the slider 8, driving the grinding assembly 10 below to move horizontally above the workpiece, and the electric telescopic rod 9 extends to make the grinding assembly 10 contact the workpiece for grinding.

[0034] During the grinding process, the circulating water pump 39 draws grinding fluid from the second filter box 13 through the water inlet pipe 41, and transports it to the nozzle 42 through the outlet pipe 40. The nozzle 42 sprays the grinding fluid onto the contact point between the grinding component 10 and the workpiece, which plays the role of cooling, lubricating and flushing debris; the outlet pipe 40 is fixed to the gantry 4 through a limit assembly, and the retractable shaping structure moves with the grinding component 10 to ensure accurate spraying.

The pressing plate 25 above the first filter box 12 is pressed, and the connecting column 26 drives the impact plate 27 to impact the cylindrical sleeve 17, shaking off the surface debris. The debris is collected by the collecting device, and the telescopic spring 24 assists the pressing plate 25 to reset.

[0037] After preliminary filtration, the polishing liquid enters the second filter box 13 through the second connecting pipe 29, first filters out fine impurities through the filter screen 30, and then absorbs oil and odor through the activated carbon screen 31; the filter screen 30 is connected to the I-shaped frame 34 through the groove 32, and the I-shaped frame 34 is fixed to the horizontal plate 36 by the connecting frame 35.
