Description

Technical Field

[0001] The invention relates to the technical field of slot hole grinding equipment, in particular to a high-precision environmentally friendly grinding device for processing the inner surface of a slot hole of a plywood. Background Art

[0002] Plywood is often used in interior decoration, furniture manufacturing, product packaging and other fields due to its advantages such as stable overall shape, large format, easy construction and uniform material. When plywood is used in different fields, slots are opened on the surface of the plywood for installation and fixation between plywood boards, or for installation and fixation with other boards, accessories, structures, or for aesthetics. Moreover, with the improvement of cutting technology and the diversified demand for products, the shapes of the slots opened on the surface of plywood are becoming more and more diversified, and the requirements for precision and quality are also getting higher and higher. In order to improve the precision and quality of the slots, a grinding device is used to grind the slots.

[0003] For example, announcement number: CN118682589A discloses "a density board fine grinding device", including: a base, a two-dimensional slide, which is arranged on the upper surface of the base, a plate clamping assembly is installed on the two-dimensional slide, and a groove is opened on the surface of the two-dimensional slide, a mounting frame, which is fixedly installed on the base, and a support frame, which is slidably arranged on the side of the mounting frame close to the two-dimensional slide.

[0004] However, in the prior art, most slot grinding equipment is designed for cylindrical slots, and its grinding head also adopts a corresponding cylindrical grinding head. When grinding the rounded rectangular slots of plywood, if a cylindrical grinding head is used to grind the inner surface of the slot, the contact portion between the circumferential surface of the grinding head and the inner surface of the slot is very narrow, and the contact track formed by these contact points is approximately a straight line in the length direction of the slot. During the grinding process, the narrow contact surface grinding tool has a limited contact area. When a certain pressure is applied, the pressure is concentrated in a smaller area, resulting in a larger cutting depth and cutting force of the abrasive particles in this area, resulting in inconsistent surface quality of the workpiece, uneven grinding, and reduced grinding accuracy. Moreover, during the grinding process, the tiny unbalanced force generated by the rotation or movement of the grinding tool can easily cause fluctuations in the contact between the grinding tool and the plywood. This fluctuation can cause the plywood to be subjected to periodic impact forces. When the rotation axis of the grinding tool is not completely perpendicular to the surface of the plywood, the narrow contact surface can more easily concentrate this unbalanced force in a smaller area, thereby causing vibration of the plywood. The vibration can cause the relative position of the grinding tool and the surface of the plywood to change continuously, resulting in inconsistent cutting depth of the abrasive on the plywood. At the same time, the width of the grinding contact surface directly affects the amount of material removed per unit time. The narrow contact surface leads to a small number of abrasive particles involved in cutting, and a reduced amount of material removed per unit time, thereby causing low grinding efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a high-precision, environmentally friendly grinding device for processing the inner surface of a plywood slot hole, so as to solve the problem proposed in the above-mentioned background technology that during the grinding process, due to the limited contact area of ​​a narrow contact surface grinding tool, when a certain pressure is applied, the pressure is concentrated in a smaller area, resulting in a larger cutting depth and cutting force of the abrasive particles in this area, causing inconsistent surface quality of the workpiece, uneven grinding, and reduced grinding accuracy. At the same time, the width of the grinding contact surface directly affects the amount of material removed per unit time.

[0017] 1. In the present invention, the third connecting plate and the contact plate installed on its side are pushed to move by extending the electric push rod. Under the pushing action of the contact plate, a certain pressure is generated between the sand belt body and the surface of the slot hole. Then, the grinding motor is turned on to drive the sand belt wheel and the sand belt body to rotate, and the surface of the slot hole is grinded by the sand belt body. The sand belt body is grinded in a rectangular plane inside the slot hole through the contact plate. Then, the three-dimensional linear adjustment mechanism drives the grinding mechanism to move along the slot hole, so that the sand belt body grinds the inside of the slot hole quickly and stably.

[0019] 3. In the present invention, the No. 1 connecting shaft is driven to rotate by the No. 1 driving mechanism, thereby driving the No. 1 mounting frame to rotate, so that the surface of the sanding belt body used for grinding the strip surface of the rounded rectangular slot hole is adjusted in position, so that the sanding belt body can grind the other two strip surfaces of the rounded rectangular slot hole. At the same time, when grinding the arc surface adjacent to the rounded rectangular slot hole, the No. 1 connecting shaft is driven to rotate by the No. 1 driving mechanism to adjust the position of the grinding mechanism 4, so that the sanding belt wheel in the grinding mechanism is close to the adjacent arc surface, so that the sanding belt body can complete the rounding. The arc surfaces of the four corners of the rectangle are ground, and the four sides and four corners of the rounded rectangular slot are ground without dead angles, so that the rounded rectangular slot is evenly and fully ground, the surface of the four corners is smooth, the stress is effectively dispersed, and the structural stability of the plywood during use is enhanced.

[0037] In this embodiment, before the grinding mechanism 4 grinds the slot hole, according to the length or width of the slot hole, the No. 1 servo motor 43 drives the No. 1 adjusting screw 44 to rotate, thereby driving the two No. 1 adjusting blocks 45 and the two No. 3 mounting frames 46 to move away from or towards each other, and at the same time, the No. 2 servo motor 47 drives the No. 2 adjusting screw 48 to rotate, thereby driving the No. 2 adjusting block 49 and the No. 1 connecting plate 411 to move towards or away from each other, and the grinding size adjustment component 41 adjusts the positions of the four grinding belt wheels 413, so that the grinding belt body 414 adjusts the width between the two sides of the slot hole grinding operation, thereby Grinding both sides of the slot hole at the same time can ensure that the grinding force and grinding time on both sides are basically the same, effectively avoiding the situation that the grinding degree of the two sides is inconsistent due to sequential grinding or unilateral grinding, making the dimensional accuracy and surface flatness of both sides of the slot hole more uniform and accurate, which is conducive to improving the processing quality of the entire slot hole. In terms of grinding efficiency, symmetrical grinding is equivalent to performing two grinding tasks at the same time. Compared with unilateral grinding in sequence, it greatly shortens the grinding time and improves the overall work efficiency. Especially in the grinding operation of batch processing of rounded rectangular slot holes, it can effectively reduce the production cycle and improve production efficiency.

[0038] When the No. 1 connecting plate 411 on the same No. 3 mounting frame 46 moves, the No. 2 slide rail 425 on its surface moves accordingly. When the No. 1 connecting plates 411 on the two No. 3 mounting frames 46 move, the No. 2 slide block 426 slides along the No. 2 slide rail 425. At this time, the No. 2 telescopic rod 427 and the No. 2 spring 428 are deformed by extension or compression, so that the position of the sand belt limiting frame 429 remains stable, and the sand belt limiting frame 429 can stably limit the sand belt body 414.

[0039] Depending on the material of the plywood being polished, the pressure applied by the sanding belt body 414 to the polishing surface of the plywood will be different. The electric push rod 417 pushes the contact plate 422 to generate pressure on the sanding belt body 414 and the polishing surface of the slot. The pressure during polishing is monitored by the pressure sensor 419 to stabilize the pressure during polishing. By controlling the appropriate polishing pressure, precise polishing can be performed according to the material characteristics to ensure that the integrity of the material is maintained while removing the surface unevenness. The stable pressure can ensure the uniformity of polishing, so that the polishing effect of the entire plywood surface or the slot is consistent, avoiding the situation of local over- or under-polishing caused by pressure fluctuations, thereby improving the polishing quality.
