Before spraying wood sheets, it is necessary to treat their surfaces to obtain a relatively smooth and flat surface in order to improve product quality.

[0003] For example, a kind of furniture manufacturing wood sheet surface finishing and grinding machine provided by the publication number CN113231935B includes a bottom plate, a placing device and a grinding device. The placing device and the grinding device are sequentially installed on the upper end of the bottom plate from left to right, and the grinding device is slidably matched with the placing device. The present invention can solve the problems that when the existing machine grinds the rounded corners on the wood sheet, it can usually only grind the rounded corners of the same arc, cannot be adjusted accordingly according to the change of the rounded corner arc, and cannot be adjusted accordingly according to the thickness and width of the wood sheet, which easily leads to the phenomenon that the rounded corners of the wood sheet are not completely ground, thus reducing the flexibility of the machine. At the same time, it cannot ensure that the machine completely fits the rounded corners on the wood sheet, and the rounded corners of the wood sheet are easily incompletely ground after grinding, thus reducing the effect of grinding the rounded corners of the wood sheet.

The limiting column 615 is movably connected inside the limiting groove 614, so that the limiting groove 614 cooperates with the limiting column 615 to guide the movement of the driving frame 608.At both the top and bottom of one end of the fixing frame 601 corresponding to the position of the second driving column 602, stoppers 616 are respectively and fixedly installed, and the stoppers 616 are in close contact with the second driving frame 607, so that when the second driving frame 607 is in the initial position under the extrusion state of the guiding column 609, the second driving frame 607 is arranged in parallel with one end of the fixing frame 601, and the centers of the six positioning balls 603 are all on the same horizontal line. When the multi-curved rounded plate 2 presses the positioning balls 603 through the rubber film 403, the positioning balls 603 will drive the second driving column 602 to move. Each group of two racks 604 will drive the gear 605 to move away from the multi-curved rounded plate 2 while meshing with it, so as to achieve the purpose of fitting each group of two positioning balls 603 with the irregular positions of the multi-curved rounded plate 2, that is, to clamp the irregular positions of the multi-curved rounded plate 2 and play a compensation clamping role at the same time. At the same time, when the three gears 605 drive the third driving column 606 to move, the second driving frame 607 will rotate around the position where it rotates with the driving frame 608, so as to meet the situation that the adjacent two third driving columns 606 move differently. Finally, the driving frame 608 moves along the guiding column 609 to one end away from the multi-curved rounded plate 2. Until the extrusion force between the multi-curved rounded plate 2 and the rubber film 403 reaches the target pressure value, that is, the longitudinal tension between the sliding seat 302 and the sealing gasket 416 detected by the pressure sensor between the sliding seat 302 and the sliding table mounting frame 418 reaches the target pressure value. At this time, the clamping of the multi-curved rounded plate 2 in the horizontal direction is completed.

[0052] Working principle: During use, the present invention first places the multi-curved rounded plate 2 on the conveying roller 102 in the transmission frame 101 for stable transmission, and orients the transmission of the multi-curved rounded plate 2 through some positioning devices (not shown in the figure). At this time, the positive and negative motor drives the screw in the screw slide table 301 to rotate, so as to drive the sliding seat 302 to move towards one end of the multi-curved rounded plate 2 in the middle of the screw slide table 301, and the sliding seat 302 drives the driving seat 401 to move towards one end of the multi-curved rounded plate 2 through the sliding table mounting frame 418;

[0053] When the driving seat 401 moves towards one end of the multi-curved rounded plate 2, the driving seat 401 cooperating with the inner cage 402 will drive the rubber film 403 to move towards one end of the multi-curved rounded plate 2. Since the driving seat 401, the inner cage 402 and the rubber film 403 are all C-shaped structures, and the position of the multi-curved rounded plate 2 corresponds to the grooves in the middle of the driving seat 401, the inner cage 402 and the rubber film 403, that is, when the driving seat 401 cooperates with the inner cage 402 to drive the rubber film 403 to move towards one end of the multi-curved rounded plate 2, the rubber film 403 will wrap the position of the multi-curved rounded plate 2 to be polished, and make the rubber film 403 closely fit with the position of the multi-curved rounded plate 2 to be polished. At the same time, the multi-curved rounded plate 2 squeezes the rotating roller 501 and the positioning ball 603 through the rubber film 403.

[0054] When the multi-curved rounded plate 2 squeezes the rotating roller 501 through the rubber film 403, the rotating rollers 501 at the upper and lower ends move away from each other, and the rotating roller 501 cooperates with the fixing plate 502 to drive the connecting rod 503 to move upward, thereby making the two sleeves 504 move relatively and squeeze the first damping spring 505. At the same time, under the action of the parallelogram formed by the first damping spring 505, the inner cage 402, the sleeve 504 and the connecting rod 503, the rotating rollers 501 at the upper and lower ends move away from each other until the multi-curved rounded plate 2 can enter the grooves in the middle of the driving seat 401, the inner cage 402 and the rubber film 403. At this time, through the reset stretching of the first damping spring 505, the first damping spring 505 cooperates with the sleeve 504, the hinge arm 506, the connecting rod 503 and the fixing plate 502 to drive the rotating roller 501 to squeeze downward, and the rotating roller 501 cooperates with the connecting rod 503 to clamp and fix the multi-curved rounded plate 2 in the vertical direction.

[0055] When the multi-curved rounded plate 2 squeezes the positioning ball 603 through the rubber film 403, it will cause the positioning ball 603 to drive the second driving column 602 to move. And when the moving distances of each pair of second driving columns 602 are different, at this time, each pair of two racks 604 will drive the gear 605 to move away from the multi-curved rounded plate 2 while meshing with it, so as to meet the purpose of fitting each pair of two positioning balls 603 with the irregular positions of the multi-curved rounded plate 2, that is, to play a compensation clamping role while clamping the irregular positions of the multi-curved rounded plate 2. When the moving distances of each pair of two second driving columns 602 are the same, at this time, each pair of two racks 604 will drive the gear 605 to move towards one end away from the multi-curved rounded plate 2, and no meshing occurs. At the same time, when the three gears 605 drive the third driving columns 606 to move different distances, it will cause the second driving frame 607 to rotate around the position where it rotates with the driving frame 608, so as to meet the situation where the adjacent two third driving columns 606 move differently. And when the three gears 605 drive the third driving columns 606 to move the same distance, it will drive the second driving frame 607 to move horizontally towards one end away from the multi-curved rounded plate 2, and finally cause the driving frame 608 to move along the guiding column 609 towards one end away from the multi-curved rounded plate 2, and squeeze the second damping spring 610 until the squeezing force between the multi-curved rounded plate 2 and the rubber film 403 reaches the target pressure value. That is, when the pressure sensor between the sliding seat 302 and the sliding table mounting frame 418 detects that the longitudinal tension between the sliding seat 302 and the gasket 416 reaches the target pressure value, at this time, the clamping of the multi-curved rounded plate 2 in the horizontal direction is completed, so that all the positioning balls 603 can be closely attached to the position to be polished of the multi-curved rounded plate 2 through the rubber film 403. And by setting the second damping spring 610, the positioning ball 603 is not locked and can move within a small range, thus meeting the requirement of polishing the multi-curved rounded plate 2 during movement, so that the multi-curved rounded plate 2 can be transported and polished at the same time. And when the multi-curved rounded plate 2 separates from the rubber film 403, under the action of the reset stretching of the second damping spring 610, the driving frame 608 will return to the initial state, that is, the driving frame 608 drives the second driving frame 607 to be closely attached to the stop block 616. At this time, all the positioning balls 603 are on the same horizontal line.

[0056] After the above-mentioned vertical and horizontal clamping of the multi-curved rounded plate 2 is completed by the vertical clamping adjustment component and the horizontal clamping adjustment component, at this time, hydraulic oil is injected into the inner holder 402 and the rubber film 403 through the oil injection pipe 7, and the hydraulic oil pressure inside the inner holder 402 and the rubber film 403 reaches the target value. At this time, the rubber film 403 will closely fit on the surface of the multi-curved rounded plate 2 in a wrapped manner. Then, the driving motor 417 is powered on to work, and the driving motor 417 drives the rotating disk 406 to rotate. Furthermore, the rotating disk 406 drives the first driving column 407 to move, and under the cooperation of the guide seat 410 and the guide rod 409, the first driving frame 408 reciprocates vertically up and down. And when the fixing strip 405 reciprocates vertically up and down, the fixing strip 405 will drive the rubber film 403 to move on the surface of the inner holder 402. Since the rubber film 403 closely fits on the surface of the multi-curved rounded plate 2 in a wrapped manner, the flexible grinding belt on the surface of the rubber film 403 will reciprocate on the surface of the multi-curved rounded plate 2 and grind the grinding position of the multi-curved rounded plate 2, thus achieving the purpose of grinding wooden plates of the type such as the multi-curved rounded plate 2 and solving the problem that it is difficult to grind the positions between the arcs.
