DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model discloses a feeding device for a cutting machine, and the overall structure is arranged as Figure 1 shown, which includes a machine case 1. Supported by the machine case 1, adjusting feet 2 are respectively installed at the four corner positions below the machine case 1, and a material plate placing mechanism is arranged on the machine case 1 and a main support arm 3 is vertically fixed.

[0027] Among them, the material plate placing mechanism can adopt the traditional lifting structure, and includes: a plate platform 21, a lifting driving cylinder and a guide rod 20.

[0028] The plate platform 21 is used for placing stacked metal thin plates to be cut. The lifting driving cylinder is located below the plate platform 21 to drive the plate platform 21 to move up and down. The guide rods 20 are distributed at the four corner positions of the plate platform 21 and are fixed to the machine case 1 through a base 22, mainly guiding the up and down movement of the plate platform 21 and can limit the stacked metal thin plates to be cut in the circumferential direction.

[0029] The main support arm 3 is a support structure vertically fixed above the machine case 1. A side vertical plate 5 is welded and fixed on one side of the top end of the main support arm 3, and an X-axis guiding mechanism is arranged based on the side vertical plate.

[0030] The X-axis guiding mechanism is used to drive the mounting block 9 to move horizontally in the X-axis direction, as Figure 1 shown, the X-axis guiding mechanism includes: a horizontal guiding arm 6, a linear guide rail, a main push cylinder 4 and an L-shaped fixing ear 8;

[0031] Among them, the horizontal guiding arm 6 is fixedly arranged on one side of the top end of the main support arm 3 through the side vertical plate 5 to provide support for the setting of the linear guide rail 7 in the X-axis direction.

[0032] The linear guide rail 7 is composed of a slideway and a slider adapted to the slideway. The slideway of the linear guide rail 7 is fixed on the horizontal guiding arm 6, and the slider of the linear guide rail 7 is fixedly connected to the mounting block 9.

[0033] For the X-axis guiding mechanism of this new type, its power mechanism is the main push cylinder 4. The L-shaped fixing ear 8 is fixed on the mounting block 9, and the main push cylinder 4 is installed on the side vertical plate 5, so that the output end of the main push cylinder 4 is locked and connected to the L-shaped fixing ear 8.

[0034] Thus, when the main push cylinder 4 starts to work, the output end of the main push cylinder 4 pushes the mounting block 9 to slide along the guidance of the linear guide rail 7 through the L-shaped fixing ear 8.

[0035] The mounting block 9 is used as an intermediate transfer structure. A double-axis cylinder 10 is fixedly assembled on one side of the mounting block 9, and the double-axis cylinder 10 drives and acts in the Y-axis direction; that is, the double-axis cylinder 10 drives the clamping mechanism composed of a vacuum chuck and a clamping plate 15 to move up and down, so as to meet the feeding requirement of the metal thin plates at the material plate placing mechanism.

[0036] To make the operation of the material clamping mechanism more flexible, a rotating motor assembly 11 is provided, so that the material clamping mechanism composed of the vacuum suction cup and the clamping plate 15 has the characteristic of being rotatable. A mounting plate 11 is fixedly connected to the output end of the double-acting cylinder 10, and a rotating motor assembly 12 is locked and assembled below the mounting plate 11; the output end of the rotating motor assembly 12 is connected to the cross brace platform 18, so that the cross brace platform 18 can be rotationally adjusted under the driving action of the rotating motor assembly 11. The rotation angle can be set according to the specific feeding requirements and the performance of the rotating motor used.

[0037] The cross brace platform 18 serves as the support structure of the material clamping mechanism. First, a vacuum suction cup 19 for vacuum-sucking the material plate (i.e., the metal thin plate) is provided below the cross brace platform 18. Considering that the existing method of feeding only by vacuum suction of the vacuum suction cup is not stable and prone to falling problems, the present invention also symmetrically provides slidable clamping plates 15 on both sides of the cross brace platform 18 to clamp the material plate (i.e., the metal thin plate).

[0038] As Figure 2 shown, the specific structure related to the clamping plate 15 is as follows: sliding holes are respectively opened at both ends of the cross brace platform 18, and sliding rods 17 are installed in the sliding holes, and the clamping plate 15 is fixedly connected to the end of the sliding rod 17; at the same time, a micro linear motor 13 is installed above the cross brace platform 18, and a connecting ear 14 is fixedly provided at the top end of the clamping plate 15, and the output end of the micro linear motor 13 is locked and connected to the connecting ear 14.

[0039] Thus, after the micro linear motor 13 is turned on, the micro linear motor 13 acts on the connecting ear 14 to pull the clamping plate 15 to move horizontally under the guiding action of the sliding rod 17.

[0040] Preferably, an anti-slip pad 16 is fixedly laid at a position near the bottom end of the inner wall of the clamping plate 15 to avoid hard contact and wear of the material plate, and the surface of the anti-slip point 16 can form ridged anti-slip strips to achieve a better clamping effect.

[0041] Thus, for the feeding device of the cutting machine disclosed in the present utility model, the stacked metal thin plates to be cut are pre-placed on the plate platform 21. When the double-axis cylinder 10 drives the vacuum suction cup and the clamping plate to the highest position, and the micro linear motor 13 pushes the clamping plate 15 to the widest position, the main push cylinder 4 drives the mounting block 9 and all the connected structures above the metal thin plate. At this time, the double-axis cylinder 10 drives the vacuum suction cup and the clamping plate to move down. After the vacuum suction cup contacts and adsorbs the metal thin plate, the micro linear motor 13 tightens the clamping plate 15 to clamp the metal thin plate. Since the pushing width of the clamping plate 15 is greater than the width of the metal thin plate when it is pushed to the widest position, the clamping plate 15 does not affect the normal contact between the vacuum suction cup and the metal thin plate. Thus, with the auxiliary effect of the clamping plate 15, the feeding device of the cutting machine of the present new type has a reliable feeding effect.

[0042] The above embodiments are not limitations to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present utility model also belong to the protection scope of the present utility model.
