Description

Technical Field

[0001] The present invention relates to the technical field of V-CUT machines, and particularly to a numerically controlled V-CUT machine with a positioning function. Background Art

[0002] A V-CUT machine is a mechanical device used to cut V-shaped grooves on the surface of materials. During the cutting process, first, the material to be processed needs to be fixed on the workbench to ensure that it does not move during the cutting process. Then, according to the predetermined cutting path, a laser or plasma cutting head cuts the material from above. The cutting process is usually precisely controlled by a computer control system to ensure the straightness of the cutting line and the cutting accuracy. Under normal circumstances, usually through the propulsion of the feeding device, the front and rear ends of the plate are clamped by the rear wall inside the machine body or a separately provided structure, and then the cutting operation is performed on the plate. However, the force generated during the cutting process mainly acts on the clamping parts. If only clamped at both ends, it is easy to cause the deformation of the plate, especially when performing deep cutting or multi-directional cutting, the problem of uneven force is more serious.

[0011] Preferably, the grid platform includes a number of supporting fixed plates installed between the front wall and the rear wall of the notch. A supporting movable plate with a length equal to the front-to-back width is arranged between two adjacent supporting fixed plates. Two positioning rods passing through the notch and the supporting movable plate are inserted on one side of the V-CUT machine body, and the positioning rods are located below the supporting fixed plates. An adjusting assembly for uniformly adjusting the distance between a number of supporting fixed plates and adjacent supporting movable plates is installed inside the notch, and the adjusting assembly is located between the two positioning rods.

[0012] Preferably, the adjusting assembly includes a docking rod located below the middle of a number of supporting movable plates.

[0034] Embodiment 1

[0035] As Figures 1 - 7As shown in the figure, this embodiment proposes a numerically controlled V-CUT machine with a positioning function, which can perform multi-directional clamping and positioning on the front, back, both sides, and top surface of the V-shaped notch plate to be engraved, ensuring that the plate has no deformation and displacement during the V-shaped notch engraving stage. The numerically controlled V-CUT machine has a notch provided on the top surface of the V-CUT machine body 1 and a grid platform 2 installed on the inner wall of the notch. A positioning mechanism 3 for multi-stage limiting along the two sides and the top surface of the V-shaped notch plate to be engraved is placed on the top of the grid platform 2. A displacement component 4 for driving the positioning mechanism 3 to move along the front-back axis and cooperating with the rear wall of the V-CUT machine body 1 to form a front-back clamping state for the V-shaped notch plate to be engraved is installed inside the V-CUT machine body 1. In actual application, the plate is placed on the grid platform 2 between the positioning mechanism 3 and the rear wall of the V-CUT machine body 1. Subsequently, by operating the displacement component 4, the positioning mechanism 3 is driven to move from front to back along the top surface of the grid platform 2 until the back surface of the plate fits against the rear wall of the V-CUT machine body 1, so that the rear wall of the V-CUT machine body 1 and the positioning mechanism 3 form a front-back clamping state for the plate. Subsequently, the positioning mechanism 3 itself is used to clamp and position the two sides and the top surface of the plate, effectively reducing the deformation and displacement that may be caused by uneven stress during the process of engraving the V-shaped notch on the plate, thereby ensuring the accuracy of the final positioning of the plate.

[0036] Continuing from the above, under normal circumstances, when clamping and positioning the two sides and the top surface of the plate, usually two sets of drive sources are required for driving and clamping, which will increase the complexity of the system structure. For example Figures 1 - 5As shown, in order to effectively reduce the application cost of the drive source, the positioning mechanism 3 includes a frame bar structure 301 placed on the top surface of the grid platform 2 and connected to the displacement assembly 4. A number of spring structures 302 are installed on the bottom wall of the frame bar structure 301, and an upper pressing assembly 303 is installed on the top of the number of spring structures 302. The upper pressing assembly 303 includes a cross bar plate 3031 connected to the top of the spring structure 302. An inclined plate 3032 is installed on the bottom of the cross bar plate 3031, an upper pressing plate 3033 is installed on the bottom of the inclined plate 3032, and a raised block 3034 is installed on the bottom of the cross bar plate 3031. Among them, when there is no external force interference on the spring structure 302, the distance between the bottom surface of the upper pressing assembly 303 and the top surface of the grid platform 2 is less than the thickness of the plate for scribing a V-shaped notch required conventionally. Limit slide bars 304 are provided on both sides inside the frame bar structure 301, and a driving assembly 305 is installed on the frame bar structure 301 for driving the two limit slide bars 304 to move horizontally along the bottom wall of the upper pressing assembly 303 to adjust the distance, and at the same time, cooperating with the undulating shape of the bottom wall of the upper pressing assembly 303 to adjust the distance between it and the grid platform 2. Before the positioning mechanism 3 clamps the top surface and both sides of the plate, the top of the limit slide bar 304 is in contact with the bottom surface of the lowest point of the raised block 3034 in the upper pressing assembly 303. And at this time, the spring structure 302 can receive an upward pulling force, prompting itself to stretch upward, so that the distance between the bottom surface of the upper pressing plate 3033 in the upper pressing assembly 303 and the top surface of the grid platform 2 is greater than the thickness of the plate for scribing a V-shaped notch required conventionally. Therefore, when the displacement assembly 4 is operated later to control the positioning mechanism 3 to move from front to back along the top surface of the grid platform 2, the front end of the plate can be made to fit the back surface of the frame bar structure 301 and be located below the upper pressing assembly 303 at the final stage. Subsequently, the driving assembly 305 is operated to control the two limit slide bars 304 to move towards each other to achieve the purpose of clamping the plate between them. Among them, with the different undulating amplitudes of the top wall of the upper pressing assembly 303, when the limit slide bars 304 move horizontally along the top wall of the upper pressing assembly 303, the external force generated on the spring structure 302 also has undulations, so as to facilitate the spring structure 302 to control the upper pressing plate 3033 to generate a downward extrusion force on the upper surface of the plate to be scribed with a V-shaped notch under the action of its own elasticity and resetability after the limit slide bar 304 is separated from the raised block 3034. Based on this, it can be clearly known that only one set of driving assembly 305 can complete the clamping and positioning of both sides and the top surface of the plate to be scribed with a V-shaped notch, avoid its deformation and lateral displacement during scribing the V-shaped notch, reduce the complexity of the structure and lower the cost.

[0037] As Figures 3 - 5As shown, the raised block 3034 is in the shape of an isosceles trapezoid, and the inclined surface of the isosceles trapezoid faces downward. The included angle between the two acute angles of the isosceles trapezoid-shaped raised block 3034 is not greater than 40°. The shape of the bottom surface of the raised block 3034 is set to facilitate the unobstructed lateral back-and-forth movement of the limit slide bar 304. The limit slide bar 304 is composed of a right trapezoidal block, a rectangular block integrally connected to one side of the right trapezoidal block, and a limit bar connected to the rear side of the right trapezoidal block. The height of the limit bar is the same as the thickness of the bottom plate of the frame structure 301. Chamfers are provided on the sides of the rectangular block and the right trapezoidal block opposite to each other. The edge chamfer setting enables the limit slide bar 304 to better pass under the raised block 3034 during the lateral movement process.

[0038] As Figure 3 shown, the drive assembly 305 includes a threaded rod 3051 rotatably mounted between the two sides of the frame structure 301, and a guide rod 3052 fixedly mounted between the two sides of the frame structure 301. One ends of the threaded rod 3051 and the guide rod 3052 both pass through the rectangular block and the right trapezoidal block. A transmission structure 3053 is mounted on the outer surface of the threaded rod 3051. A stepping motor 3054 for driving the threaded rod 3051 to rotate through the transmission structure 3053 is mounted on the front surface of the frame structure 301. The stepping motor 3054 is used as the drive source, and its operation principle and program are basically the same as those of the prior art. It is designed to control the uniform rotation of the threaded rod 3051 through its operation, thereby driving the two limit slide bars 304 to move in opposite or relative directions to adjust the spacing.

[0039] Embodiment 2

[0040] Continuing from the above, during the process of using a V-CUT machine to engrave V-shaped cuts on the surface of a sheet, some waste materials will be formed. After the waste materials break away from the sheet, they will directly pass through the grid platform 2 and fall downward into the collection space of the V-CUT machine body 1 itself. However, since the waste materials generated by the V-CUT machine are not of uniform size and shape. Some waste materials may be relatively large or heavy and may get stuck between the grid platforms 2, resulting in the inability to fall through the grid platform 2. In order to effectively solve this problem. As Figure 1 、 Figures 6 - 7As shown in the figure, the above-mentioned grid platform 2 includes several supporting fixed plates 201 installed between the front wall and the rear wall of the notch. Between two adjacent supporting fixed plates 201, there is a supporting movable plate 202 with a length consistent with the front-to-back width. Through the arrangement of several supporting movable plates 202 and supporting fixed plates 201 at intervals, a platform with the same top surface height is formed at the feeding place of the V-CUT machine body 1, so as to facilitate the horizontal placement of the plates. Two positioning rods 203 passing through the notch and the supporting movable plate 202 are inserted into one side of the V-CUT machine body 1, and the positioning rods 203 are located below the supporting fixed plates 201. The adjusting component 204 installed inside the notch is used to uniformly adjust the distance between several supporting fixed plates 201 and the adjacent supporting movable plates 202, aiming to flexibly meet the dropping requirements of different types of waste. When the waste is in a larger block, the adjusting component 204 can be used to make the supporting movable plate 202 fit with the adjacent supporting fixed plate 201, so as to expand the overall distance of the grid platform 2 and facilitate the smooth passage of the waste. Moreover, several supporting movable plates 202 move back and forth between two adjacent supporting fixed plates 201, which can make the waste originally stably placed on the top of the supporting fixed plates 201 or supporting movable plates 202 shake and then fall down.

[0041] Specifically, the adjusting component 204 is located between the two positioning rods 203. The adjusting component 204 includes a docking rod 2041 located below the middle parts of several supporting movable plates 202. At the middle parts of the bottom surfaces of several supporting movable plates 202, clamping plates 2042 are installed. A U-shaped groove with a width consistent with the diameter of the docking rod 2041 is opened on the clamping plate 2042. On both sides of the clamping plate 2042, positioning rings 2043 are arranged and sleeved on the surface of the docking rod 2041 through threads. An electric push rod 2044 detachably connected to the docking rod 2041 is installed on the inner wall of one side of the notch. Through the extension and contraction operations of the electric push rod 2044, the docking rod 2041 is forced to move intermittently back and forth horizontally. At the same time, through the clamping plate 2042 clamped between the two positioning rings 2043, a driving force and a pulling force in the same direction are generated on several supporting movable plates 202, so that the supporting movable plates 202 move intermittently back and forth between two adjacent supporting fixed plates 201.

[0042] Embodiment 3

[0043] As Figure 1 and Figure 7As shown, a cylindrical groove interconnected with the notch is provided on the V-CUT body 1, and a telescopic sleeve 2045 is detachably connected to the inner wall of the cylindrical groove, and the interior of the telescopic sleeve 2045 is connected to one end of the docking rod 2041 by a threaded rotation. In accordance with the above, while the docking rod 2041 moves laterally, the telescopic sleeve 2045 itself is acted upon by an external force, and its length is adjusted accordingly. The telescopic sleeve 2045 itself is mainly used to connect one end of the docking rod 2041 to keep it balanced. In addition, the entire grid platform 2 can be disassembled, which is convenient for increasing the number of supporting movable plates 202 according to actual needs. Among them, when disassembling the docking rod 2041, first separate it from the electric push rod 2044, then control the inner cylinder of the telescopic sleeve 2045 and rotate the entire docking rod 2041, so that one end of it is separated from the inner cylinder of the telescopic sleeve 2045, and then drive the docking rod 2041 to move downward, so that the positioning ring 2043 and the clamping plate 2042 can be separated. Then, the two positioning rods 203 can be pulled out from the V-CUT body 1 to achieve the purpose of removing the supporting movable plate 202 .

[0044] like Figure 1 As shown, the displacement assembly 4 includes a screw structure 401 rotatably mounted inside the V-CUT body 1, a servo motor 402 connected to the screw structure 401 is also installed inside the V-CUT body 1, and a slider structure 403 is sleeved on the outer surface of the screw structure 401, and a connecting frame 404 is installed on the top of the slider structure 403, which passes through the grid platform 2 and is fixedly fitted with the outer walls of the two sides of the frame structure 301. When the servo motor 402 is running, the screw structure 401 is controlled to rotate at a constant speed in the set direction, thereby driving the slider structure 403 to drive the connecting frame 404 to move from front to back along the top surface of the grid platform 2, thereby driving the positioning mechanism 3 to push the plate placed on the top surface of the grid platform 2 from front to back, so that the rear end of the plate is fitted with the rear wall of the V-CUT body 1, and at this time, the front and rear ends of the plate are clamped.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
