Description

Technical Field

[0001] The utility model relates to the technical field of plate transportation and clamping, in particular to an air-floating transportation and auxiliary clamping device for plates. Background Technique

[0002] After the plate is cut, it needs to be transported to a grinding machine tool for grinding. When transporting the plate, if the weight of the plate is heavy, it cannot be supported by the transportation belt alone. Therefore, the transportation method of such plates is usually manual handling, that is, the staff transports the plate from the cutting machine tool to the grinding machine tool, and then clamps the plate through the upper fixture and the lower fixture of the grinding machine tool for grinding. However, manual handling of the plate is likely to consume the physical strength of the staff, and there are also certain safety hazards during the handling process; moreover, when the grinding machine tool grinds, it directly contacts the top surface of the plate, and the friction between the upper fixture of the grinding machine tool and the top surface of the plate during the grinding process is small and prone to slipping, resulting in grinding errors; in addition, the upper fixture is also likely to damage the top surface of the plate.

[0024] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but not to limit the scope of the present utility model.

[0025] As Figures 1 to 5 shown, an air floating transportation and auxiliary clamping device for a plate provided by the present utility model includes an air floating transportation component and an upper auxiliary clamping component;

[0026] The air floating transportation component includes a first air floating plate 1, a second air floating plate 2 and a plurality of air floating beads 22. An air floating groove 11 is opened on the top surface of the first air floating plate 1. A plurality of air floating through holes 21 are opened on the second air floating plate 2. The bottom diameter of the air floating through hole 21 is larger than the diameter of the air floating bead 22. The middle diameter of the air floating through hole 21 is greater than or equal to the diameter of the air floating bead 22. The top diameter of the air floating through hole 21 is smaller than the diameter of the air floating bead 22. The vertical distance between the top end of the air floating through hole 21 and the bottom surface of the air floating groove 11 is larger than the diameter of the air floating bead 22. The diameter of the air floating bead 22 is larger than the opening depth of the air floating groove 11. The opening positions of the plurality of air floating through holes 21 correspond to the opening positions of the air floating groove 11. The plurality of air floating beads 22 are clamped between the air floating groove 11 and the plurality of air floating through holes 21. The first air floating plate 1 is provided with a ventilation hole 13. The ventilation hole 13 is connected to a blower. The ventilation hole 13 communicates with the air floating groove 11. First connection holes 12 are opened at the four corners of the top surface of the first air floating plate 1. First connection shafts 23 are connected to the four corners of the bottom surface of the second air floating plate 2. The first air floating plate 1 and the second air floating plate 2 are connected through the first connection holes 12 and the first connection shafts 23. The top surface of the second air floating plate 2 abuts against the bottom surface of the plate 7. The first air floating plate 1 and the second air floating plate 2 are used to be connected to the lower fixture of the grinding machine;

[0027] The upper auxiliary clamping assembly includes an upper clamping plate 4 and a lower clamping plate 5. Second connecting shafts 41 are connected to the four corners of the bottom surface of the upper clamping plate 4. Second connecting holes 51 are provided at the four corners of the top surface of the lower clamping plate 5. The upper clamping plate 4 and the lower clamping plate 5 are connected through the second connecting shafts 41 and the second connecting holes 51. The bottom surface of the lower clamping plate 5 is used to abut against the top surface of the plate 7. The upper clamping plate 4 and the lower clamping plate 5 are used to connect to the upper fixture of the grinding machine.

[0028] Specifically, the diameter of the top of the air floating through hole 21 in the present utility model is 18.4 mm. The plate 7 applicable to the present utility model can be a light guide plate, a PVC plate, etc.

[0029] In the present utility model, the longitudinal cross-sectional shape of the air floating through hole 21 can be trapezoidal or a semi-circular shape with the top removed.

[0030] By providing an air floating groove 11 on the top surface of the first air floating plate 1, a plurality of air floating through holes 21 are provided on the second air floating plate 2. The opening positions of the plurality of air floating through holes 21 correspond to the opening position of the air floating groove 11. A plurality of air floating beads 22 are clamped between the air floating groove 11 and the plurality of air floating through holes 21. A ventilation hole 13 is provided on the first air floating plate 1. The ventilation hole 13 is connected to a blower. The ventilation hole 13 communicates with the air floating groove 11. The plate 7 is placed on the top surface of the second air floating plate 2. When the blower is started, the blower ventilates between the first air floating plate 1 and the second air floating plate 2 through the ventilation hole 13, so that the air of the blower is concentrated in the air floating groove 11. Further, the air floating beads 22 float upward due to the air buoyancy. And since the bottom diameter of the air floating through hole 21 is larger than the diameter of the air floating bead 22, the top diameter of the air floating through hole 21 is smaller than the diameter of the air floating bead 22, and the middle diameter of the air floating through hole 21 is greater than or equal to the diameter of the air floating bead 22. Therefore, when the air floating bead 22 floats upward, the middle part of the air floating bead 22 can be stuck in the air floating through hole 21, so that the top of the air floating bead 22 can be higher than the top surface of the second air floating plate 2, but will not break away from the air floating through hole 21. When the staff pushes the plate 7, the plurality of air floating beads 22 roll in the air floating through hole 21, so that the plate 7 can be transported on the surfaces of the plurality of air floating beads 22, reducing the physical consumption of the staff and the possibility of safety accidents during handling.

[0031] By connecting the upper clamping plate 4 and the lower clamping plate 5 through the second connecting shafts 41 and the second connecting holes 51, when grinding the plate 7, the upper clamping plate 4 and the lower clamping plate 5 are placed on the top surface of the plate 7. The upper fixture of the grinding machine abuts against and connects to the upper clamping plate 4. Then, in cooperation with the first air floating plate 1 and the second air floating plate 2 on the bottom surface of the plate 7, the grinding machine can stably clamp the plate 7, avoiding the situation of slipping due to direct contact between the upper fixture and the plate 7, reducing the grinding error, and also avoiding damage to the top surface of the plate 7 by the upper fixture.

[0032] The first air flotation plate 1 and the second air flotation plate 2 are connected through the first connection holes 12 and the first connection shafts 23, and the upper clamping plate 4 and the lower clamping plate 5 are connected through the second connection shafts 41 and the second connection holes 51, which can enable simple alignment connections between the first air flotation plate 1 and the second air flotation plate 2, and between the upper clamping plate 4 and the lower clamping plate 5, facilitating the connection positioning when the fasteners connect the first air flotation plate 1 and the second air flotation plate 2 and the connection positioning when the fasteners connect the upper clamping plate 4 and the lower clamping plate 5.

[0033] Optionally, the air flotation grooves 11 include two I-shaped grooves 111, and the two I-shaped grooves 111 are distributed in parallel on the top surface of the first air flotation plate 1; the opening positions of the plurality of air flotation through holes 21 correspond to the opening positions of the two I-shaped grooves 111.

[0034] In a specific embodiment, the plurality of air flotation through holes 21 in the present utility model can be evenly divided into four groups of air flotation through hole groups on the second air flotation plate 2, and the opening position of each group of air flotation through hole groups corresponds to the opening position of one transverse part of one of the I-shaped grooves 111.

[0035] Optionally, the first air flotation plate 1 and the second air flotation plate 2 are also connected through a plurality of fasteners, and the upper clamping plate 4 and the lower clamping plate 5 are also connected through a plurality of fasteners. Specifically, the fasteners in the present utility model are screws.

[0036] In a specific embodiment, a plurality of fasteners fix the first air flotation plate 1 and the second air flotation plate 2, so that the connection between the first air flotation plate 1 and the second air flotation plate 2 is tight and can form a relatively closed space. When the blower ventilates the air flotation groove 11 through the ventilation holes 13, the introduced air can be non-leaking and gathered in the air flotation groove 11, so that the plurality of air flotation beads 22 float upward.

[0037] By arranging a plurality of fasteners to fix the upper clamping plate 4 and the lower clamping plate 5, during the grinding process, the upper clamping plate 4 and the lower clamping plate 5 will not easily separate from each other, ensuring the stability of the connection between the fixture on the grinding machine tool and the upper auxiliary clamping assembly, thereby reducing the generation of grinding errors.

[0038] Optionally, a plurality of first positioning holes 3 for connecting with the lower fixture of the grinding machine tool are opened on both the first air flotation plate 1 and the second air flotation plate 2; a plurality of second positioning holes 6 for connecting with the upper fixture of the grinding machine tool are opened on both the upper clamping plate 4 and the lower clamping plate 5.

[0039] The first air flotation plate 1 is abutted against the lower fixture of the grinding machine tool, and the upper clamping plate 4 is abutted against the upper fixture of the grinding machine tool, thereby stably clamping the plate 7 and preventing the plate 7 from shifting during the grinding process.

[0040] Optionally, the first air flotation plate 1 and the lower clamping plate 5 are both aluminum plates, and the second air flotation plate 2 and the upper clamping plate 4 are both bakelite plates.

[0041] Specifically, the size of the bakelite board in the present utility model is larger than that of the aluminum plate, enabling the bakelite board to match aluminum plates of different sizes. Even if the size of the aluminum plate changes, it can still be combined with the bakelite board in the present utility model, reducing the replacement cost of the bakelite board. Moreover, since the cost of the aluminum plate is high, in practical applications, the area of the aluminum plate can be reduced on the premise of meeting the requirements of air-floating transportation and auxiliary clamping, thereby reducing the manufacturing cost.

[0042] It should be noted that when aluminum plates of different sizes are combined with the same bakelite board, the size of the aluminum plate needs to be smaller than the size of the currently used bakelite board. If the size of the aluminum plate is larger than the size of the currently used bakelite board, a bakelite board with a larger size needs to be replaced.

[0043] Furthermore, the size of the first air-floating plate 1 in the present utility model is 786mm×326.5mm×25mm, the size of the second air-floating plate 2 is 798mm×335mm×15mm, the size of the upper clamping plate 4 is 786mm×326.5mm×20mm, and the size of the lower clamping plate 5 is 798mm×335mm×15mm.

[0044] Of course, the sizes of the first air-floating plate 1, the second air-floating plate 2, the upper clamping plate 4, and the lower clamping plate 5 can be changed according to the actual situation of on-site grinding, as long as the sizes of the first air-floating plate 1 and the lower clamping plate 5 are the same, and the sizes of the second air-floating plate 2 and the upper clamping plate 4 are the same.

[0045] If both the second air-floating plate 2 and the lower clamping plate 5 are made of aluminum plates, the manufacturing cost of the air-floating transportation component and the upper auxiliary clamping component is relatively high. If both the first air-floating plate 1 and the upper clamping plate 4 are made of bakelite boards, when the air-floating transportation component transports a relatively heavy plate 7, the supporting force of the first air-floating plate 1 is weak, and when the upper fixture of the grinding machine cooperates with the upper auxiliary clamping component to clamp the plate 7, it is easy to slip between the lower clamping plate 5 and the top surface of the plate 7.

[0046] Since the first air-floating plate 1 in the present utility model is made of an aluminum plate and has a relatively high strength, it is possible to open air-floating grooves 11 with a relatively large area. Therefore, two I-shaped grooves 111 are opened as the air-floating grooves 11 in the present utility model. If the first air-floating plate 1 is made of a bakelite board or other materials with relatively low strength, a plurality of neatly arranged square-shaped grooves can be opened as the air-floating grooves 11, and the opening positions of the corresponding plurality of air-floating through holes 21 should also change with the change of the opening shape and position of the air-floating grooves 11.

[0047] In summary, the air-floating transportation and auxiliary clamping device for the board provided by the present utility model can transport the relatively heavy board 7 through the floating air-floating beads 22, eliminating the need for manual handling, reducing the physical consumption of the staff and the possibility of safety accidents during handling; by placing the upper clamping plate 4 and the lower clamping plate 5 on the top surface of the board 7 and placing the bottom surface of the board 7 on the first air-floating plate 1 and the second air-floating plate 2, it can achieve the auxiliary clamping of the board 7 by the grinding machine tool, avoiding the situation of slipping due to the direct contact between the upper fixture and the board 7, reducing the grinding error, and preventing the upper fixture from damaging the top surface of the board 7.

[0048] The above description is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
