Description

Technical Field

[0001] This utility model relates to the field of stone processing equipment technology, and in particular to a CNC stone edge grinding machine. Background Technology

[0002] In the field of stone processing, CNC stone edge grinding machines are key equipment for achieving fine edge processing of stone, and their technological development directly affects the processing efficiency and product quality of industries such as building decoration and home building materials.

[0003] Currently available CNC stone edging machines still face numerous technical bottlenecks in practical applications: traditional equipment often employs a fixed structure design, and the operating table for placing the stone lacks flexible steering adjustment capabilities, making it difficult for the grinding head to adapt to the edging needs of complex-shaped stones such as curved and irregular shapes. This is especially problematic when processing slabs of different sizes, requiring frequent machine stops for adjustments, severely restricting processing efficiency. Cooling systems often use a single-direction spray structure, resulting in limited coolant coverage. This not only fails to effectively reduce high-temperature wear on the grinding head but may also cause stone cracking due to localized overheating, affecting processing quality and equipment lifespan. Components used to fix the stone are mostly rigidly designed, unable to adapt to the subtle undulations on the stone surface. Displacement due to vibration during processing can lead to increased edging dimensional errors. Furthermore, existing wastewater treatment systems typically employ a simple bottom collection method, lacking a guiding structure and rapid discharge mechanism. The mixture of coolant and grinding debris can easily clog pipes, polluting the working environment and increasing maintenance costs.

[0004] As the stone processing industry develops towards high precision and personalized customization, the shortcomings of traditional CNC edge grinding machines in terms of structural flexibility, processing accuracy retention, cooling efficiency, and environmental performance are becoming increasingly prominent, and there is an urgent need to achieve a comprehensive improvement in equipment performance through technological innovation.

[0041] Working principle: When in use, first turn on the power and open the door. Then place the stone to be processed on the tray 2. Start the equipment through the control panel 6. The output shaft of motor 1 3 drives the tray 2 to rotate to a suitable angle through gear 31 and gear plate 32 so as to process different edges of the stone. Then, motor 2 412 drives the sliding seat 41 to move along the guide frame 4 through adjusting screw 411, adjusting the longitudinal position of the grinding head 431 so that it is close to the area of ​​the stone to be ground. Subsequently, motor 3 512 drives the bidirectional screw 511 to rotate, adjusting the distance between the two sliders 51, so that the two positioning frames 52 can be adjusted to a suitable position for positioning the stone in the tray 2. Then, the strip plate 5 is moved down by the electric cylinder 2 501, so that the positioning frame 52 presses the stone surface under the action of spring 521 to ensure that it remains stable during processing.

[0042] After positioning is completed, the electric cylinder 42 pushes the mounting base 421, causing the grinding head 431 to contact the edge of the stone. At the same time, the grinding motor 43 starts, driving the grinding head 431 to rotate at high speed and begin the edge grinding operation. Meanwhile, coolant is introduced into the annular pipe 441 through the conveying pipe 44 and evenly sprayed onto the grinding head 431 and the stone processing area by multiple nozzles 442, effectively reducing temperature and dust. The cooling waste liquid generated during the grinding process flows into the guide groove 201 at the bottom of the tray 2, is collected by the hollow shaft 21, and is discharged from the discharge pipe, ensuring a clean working environment and efficient operation of the equipment.

[0043] Operators can monitor the processing status inside the box 1 in real time through the observation window. If necessary, the equipment can be paused for adjustment or inspection. The entire processing process is uniformly controlled by the control panel 6, and the modules work together to achieve automated and precise stone edge grinding, which significantly improves work efficiency and product quality.
