Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing, and specifically provides an automatic edge-fitting and positioning device for a sheet metal cutting machine. Background Technology

[0002] Panel cutting machines are used in industrial production to process various types of panels. They can perform processes such as cutting, drilling, grooving, milling, and carving on panel furniture. Before processing, the panels need to be positioned and aligned before being fed into the panel cutting machine to obtain panels with specific shapes.

[0003] Currently, the positioning of sheet metal is typically achieved by using reciprocating mechanisms such as cylinders to move the sheet metal to fit against a positioning plate. However, this method involves the reciprocating mechanism pressing on the sheet metal, which can easily damage its edges, creating gaps or debris. This affects the edge quality of the sheet metal and makes subsequent edge sealing difficult.

[0004] Therefore, there is an urgent need for an automatic edge-fitting and positioning device for board cutting machines to solve the problem that current board cutting machines easily damage the edges of the boards. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the positioning device of the existing board cutting machine is prone to damaging the edge of the board during the process of moving and positioning the board.

[0006] In a first aspect, this utility model provides an automatic edge-fitting and positioning device for a sheet metal cutting machine, comprising: a frame placed on the ground, wherein a limiting component is provided on one side of the frame along a second direction, the limiting component extending along a first direction; a drive mechanism installed on the frame for driving the sheet metal to move along the first direction; and a roller assembly installed on the frame, wherein the sheet metal is located above the roller assembly, including a first roller group, the first roller group including a first rotating shaft and a plurality of first rollers, the first rollers being fixed at intervals on the first rotating shaft, the first rotating shaft being rotatably connected to the frame, the first rotating shaft being inclined in the second direction along a direction away from the limiting component and in the first direction along a direction toward the cutting machine, wherein the sheet metal automatically fits against the limiting component during the process of moving toward the cutting machine under the action of the first roller group.

[0007] By adopting the above technical solution, as the plate moves along the first direction on the roller assembly under the drive of the drive mechanism, the rolling friction between the plate and the first roller is perpendicular to the first rotating shaft and points towards the limiting component. Under the drive of the friction, the plate gradually approaches the limiting component and the side edge is attached to the limiting component, realizing automatic edge positioning without damaging the plate.

[0008] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned sheet metal cutting machine, the roller assembly further includes a second roller group, the second roller group includes a second rotating shaft and a plurality of second rollers, the second rollers are fixed at intervals on the second rotating shaft, the second rotating shaft is arranged along the second direction and is rotatably connected to the frame.

[0009] By adopting the above technical solution, the second roller comes into contact with the board, reducing the friction during the movement of the board.

[0010] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned board cutting machine, the first roller group and the second roller group are alternately arranged in the first direction.

[0011] By adopting the above technical solution, the alternating arrangement of the first roller group and the second roller group can reduce the friction during the movement of the plate, and at the same time, it can intermittently position the plate against the edge, ensuring that the plate can always fit the limiting component.

[0012] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned sheet metal cutting machine, the limiting component includes a contact roller, which rotates in a third direction.

[0013] By adopting the above technical solution, the friction between the plate and the limiting component can be reduced.

[0014] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned board cutting machine, the driving mechanism includes a driving sprocket, a driven sprocket, a chain, and a push plate. The chain meshes with the driving sprocket and the driven sprocket. The push plate is installed on the chain and located on the outside of the chain. The push plate can contact the board to push the board to move along the first direction.

[0015] By adopting the above technical solution, the rotation of the drive sprocket can drive the chain to rotate, thereby driving the push plate fixed on the chain to move. After the push plate comes into contact with the plate, it can push the plate to move along the first direction.

[0016] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned board cutting machine, the plane on which the frame is located is divided into a first region, a second region and a third region extending along the first direction. In the second direction, the second region is located between the first region and the third region. The roller assembly is disposed in the first region and the third region, and the driving mechanism is disposed in the second region.

[0017] By adopting the above technical solution, the drive mechanism and the roller assembly are arranged in different areas, which can effectively avoid interference between the drive mechanism and the roller assembly.

[0018] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned board cutting machine, a ball bearing is embedded on one side of the push plate near the board.

[0019] By adopting the above technical solution, during the process of the plate moving towards the limiting component in the second direction, the friction between the push plate and the plate is transformed into rolling friction, thereby effectively reducing the friction between the push plate and the plate.

[0020] In a specific embodiment of the automatic edge-fitting and positioning device of the above-mentioned board cutting machine, a distance sensor is installed on the frame, and the distance sensor is used to measure the moving distance of the board along the first direction.

[0021] By adopting the above technical solution, after the ranging sensor measures the distance the board moves along the first direction, it can control the drive mechanism to close, and then use the cutting machine to process the board to perform operations in a specific area of ​​the board.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The automatic edge-fitting and positioning device for a sheet metal cutting machine provided by this utility model includes a frame, a drive mechanism, and a roller assembly. A limit component is provided on one side of the frame along a second direction. The drive mechanism drives the sheet metal to move along a first direction. The sheet metal is located above the roller assembly, which includes a first roller group, a first rotating shaft, and multiple first rollers. The first rollers are fixed at intervals on the first rotating shaft, which is rotatably connected to the frame. The rotating shaft is inclined in the second direction away from the limit component and in the first direction towards the cutting machine. Under the action of the first roller group, the sheet metal automatically fits against the limit component as it moves towards the cutting machine. As the sheet metal moves along the first direction on the roller assembly under the drive of the drive mechanism, the rolling friction between the sheet metal and the first rollers is perpendicular to the first rotating shaft and points towards the limit component. Driven by this friction, the sheet metal gradually approaches the limit component and its side edge fits against it, achieving automatic edge-fitting and positioning without damaging the sheet metal.

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] To address the problem that existing panel cutting machines' positioning devices easily damage the edges of the panels during the moving and positioning process, this invention provides an automatic edge-fitting positioning device for panel cutting machines.

[0033] like Figure 1 and Figure 2As shown, the positioning device includes a frame 1, a limiting component 2, a drive mechanism 3, and a roller assembly. The frame 1 is placed on the ground, and the limiting component 2 is installed on one side of the frame 1 along the second direction Y, extending along the first direction X. The first direction X and the second direction Y are both horizontal and perpendicular to each other. A cutting machine 6 is located at one end of the frame 1 along the first direction X. The drive mechanism 3 is installed on the frame 1 and is used to drive the sheet metal 5 to move towards the cutting machine 6 along the first direction X. The roller assembly is installed on the frame 1, and the sheet metal 5 is placed above the roller assembly. During the movement of the sheet metal 5 towards the cutting machine 6 along the first direction X on the roller assembly, the roller assembly enables the sheet metal 5 to automatically conform to the limiting component 2, achieving automatic positioning. During the automatic positioning process of the sheet metal 5 moving along the second direction Y, no active drive component (such as a cylinder) applies pressure to the sheet metal 5, therefore, the edges of the sheet metal 5 will not be damaged.

[0034] like Figure 1 As shown, the roller assembly includes multiple first roller groups 41. Each first roller group 41 includes a first rotating shaft 411 and multiple first rollers 412. The first rollers 412 are fixed at intervals on the first rotating shaft 411. The first rotating shaft 411 is rotatably connected to the frame 1. The first rotating shaft 411 is inclined in the second direction Y away from the limiting component 2 and in the first direction X towards the cutting machine 6. As the sheet metal 5 moves along the first direction X on the roller assembly under the drive of the drive mechanism 3, the rolling friction between the sheet metal 5 and the first rollers 412 is perpendicular to the first rotating shaft 411 and points towards the limiting component 2. Driven by the friction, the sheet metal 5 gradually approaches the limiting component 2 and its side edge adheres to the limiting component 2, achieving automatic edge positioning without damaging the sheet metal 5.

[0035] In some examples, such as Figure 1 As shown, the roller assembly also includes multiple second roller groups 42. Each second roller group 42 includes a second rotating shaft 421 and multiple second rollers 422. The second rollers 422 are fixed at intervals on the second rotating shaft 421, which is arranged along the second direction Y and rotatably connected to the frame 1. During the movement of the plate 5 along the first direction X, there is complete rolling contact between the plate 5 and the second rollers 422, which can effectively reduce the frictional resistance during the movement of the plate 5.

[0036] For example, the first roller group 41 and the second roller group 42 are alternately arranged in the first direction X. After the first roller group 41 and the second roller group 42 are alternately arranged, the friction of the plate 5 during the movement can be reduced under the action of the second roller group 42. At the same time, the plate 5 can also be intermittently positioned by the second roller group 42 to ensure that the plate 5 can always fit the limiting component 2.

[0037] In some examples, such as Figure 2 As shown, the limiting component 2 includes a contact roller 21. The contact roller 21 rotates in the third direction Z. During the process of the plate 5 contacting the limiting component 2 and moving in the first direction X, the contact roller 21 can reduce the friction between the plate 5 and the limiting component 2.

[0038] In some examples, the drive mechanism 3 includes a drive sprocket 31, a driven sprocket 32, a chain 33, and a pusher plate 34. The chain 33 meshes with the drive sprocket 31 and the driven sprocket 32. The pusher plate 34 is mounted on the chain 33 and located outside the chain 33. The pusher plate 34 can contact the plate 5 to push the plate 5 to move along the first direction X. After the drive sprocket 31 rotates, it can drive the chain 33 to rotate, thereby driving the pusher plate 34 fixed on the chain 33 to move. After the pusher plate 34 contacts the plate 5, it can push the plate 5 to move along the first direction X.

[0039] Of course, it should be noted that the above description of the structure of the drive mechanism 3 is merely an example and does not represent a specific limitation of this utility model. Without departing from the principle of this utility model, the drive mechanism 3 can be set as any structure capable of driving the plate 5 to move along the first direction X, such as a cylinder, a linear module, etc.

[0040] For example, a ball bearing is embedded on one side of the push plate 34 near the plate 5. As the plate 5 moves toward the limiting component 2 in the second direction Y, the friction between the push plate 34 and the plate 5 is converted into rolling friction, thereby effectively reducing the frictional force between the push plate 34 and the plate 5.

[0041] For example, such as Figure 1 As shown, the plane containing the frame 1 is divided into a first region 11, a second region 12, and a third region 13 extending along the first direction X. In the second direction Y, the second region 12 is located between the first region 11 and the third region 13. The roller assembly is disposed in the first region 11 and the third region 13, and the drive mechanism 3 is disposed in the second region 12. The drive mechanism 3 and the roller assembly are arranged in different regions, effectively avoiding interference between them.

[0042] In addition, a distance sensor is installed on the frame 1 to measure the distance the sheet metal 5 moves along the first direction X. After the distance sensor measures the distance the sheet metal 5 moves along the first direction X, it can control the drive mechanism 3 to close, and then use the cutting machine to process the sheet metal 5 in a specific area.

[0043] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
