Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to a multi-grip device for sheet metal and a CNC six-sided drill. Background Technology

[0002] The use of six-sided drilling machines is becoming increasingly common in the production of panel furniture. Their functions are also expanding beyond simple drilling and grooving; many manufacturers are now applying them to panel cutting and laminar flow processing. Currently, CNC six-sided drilling machines typically use only two gripper assemblies to perform tasks such as pressing, feeding, positioning, and unloading. However, traditional double-gripper assemblies cannot handle the diverse needs of short, narrow, long, and irregularly shaped panels, requiring frequent clamping changes to avoid the processing area. This leads to decreased processing accuracy. When processing long workpieces, insufficient support rigidity can easily cause bending deformation, increasing processing time by more than 30%. Furthermore, under alternating heavy loads, inertial shifts can occur, accelerating wear on the transmission structure and affecting the equipment's lifespan.

[0003] Therefore, there is an urgent need for a multi-grip device for sheet metal and a CNC six-sided drill to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a multi-grip device for sheet metal, which can dynamically combine various clamping modes to adapt to the clamping requirements of workpieces of different sizes and shapes. At the same time, it enhances the structural stability under alternating heavy loads, realizes the completion of all processing steps in one clamping, and effectively solves the problems of low processing efficiency, poor accuracy and high wear of traditional equipment.

[0005] Another objective of this utility model is to provide a CNC six-sided drill, which includes the above-mentioned multi-grip device for sheet metal.

[0006] To achieve the above objectives, this utility model provides a multi-grip device for sheet metal, which includes a crossbeam and at least three sheet metal grippers slidably mounted on the crossbeam. The multiple sheet metal grippers are arranged sequentially on the crossbeam along its length. The sheet metal grippers can be initially positioned on the crossbeam and can slide along the length of the crossbeam during processing. Each sheet metal gripper includes a lower clamping seat, an upper clamping seat, and a cylinder. The cylinder is mounted on the lower clamping seat, and the upper clamping seat is located above the lower clamping seat. The upper clamping seat is mounted on the output end of the cylinder, and the cylinder drives the upper clamping seat to move up and down towards and away from the lower clamping seat.

[0007] Preferably, the clamping width of one of the board clamps is greater than the clamping width of the other board clamps.

[0008] Ideally, multiple sheet metal clamps slide synchronously in the same direction on the crossbeam during processing.

[0009] Preferably, the plate clamp also includes a positioning element for positioning the edge of the workpiece. The positioning element is installed in the lower clamp and is located between the upper clamp and the lower clamp. The upper clamp has a through hole for the positioning element to pass through, and the through hole is positioned directly opposite the positioning element.

[0010] Preferably, the lower clamping seat is equipped with a lower clamping pad, which is located on one side of the positioning member. The upper clamping seat is equipped with an upper clamping pad, which is located directly above the lower clamping pad. The upper clamping pad and / or the lower clamping pad are provided with anti-slip grooves.

[0011] Preferably, the lower clamp includes a mounting body and a support body. The support body is mounted on the mounting body in a way that allows it to slide up and down. A spring is provided between the support body and the mounting body. The spring always has a tendency to push the support body upward. A cylinder is mounted on the support body. The piston rod of the cylinder passes through the support body and is connected to the upper clamp. The upper clamp is mounted on the mounting body in a way that allows it to slide up and down.

[0012] Preferably, the upper clamping seat includes a clamping seat body and a sliding structure body. The sliding structure body is mounted on the mounting seat body in a way that allows it to slide up and down. The clamping seat body is connected to the sliding structure body and is located directly above the support seat body. The mounting seat body is equipped with a blocking structure. A stop structure is installed at the lower end of the sliding structure body. The stop structure is located below the blocking structure and directly opposite the blocking structure. The piston rod of the cylinder is connected to the clamping seat body. The cylinder drives the clamping seat body to move upward and away from the support seat body until the stop structure presses against the blocking structure, thereby opening the jaws of the plate clamping hand. The cylinder further applies upward force to the clamping seat body, driving the support seat body to slide downward and compress the spring, thereby further opening the jaws of the plate clamping hand.

[0013] Preferably, a clearance notch is provided on one side of the end of the support base and clamping base of the partial plate clamp.

[0014] Preferably, the crossbeam is equipped with a long slide rail arranged along the length of the crossbeam, the mounting base is equipped with a slider that slides on the long slide rail, and the plate clamp also includes an adjustment motor, which is mounted on the mounting base and drives the plate clamp to slide and adjust along the length of the crossbeam.

[0015] To achieve another objective mentioned above, this utility model provides a CNC six-sided drill, including the aforementioned multi-grip device for sheet metal. The CNC six-sided drill also includes a work platform, and the crossbeams of the multi-grip device for sheet metal are spaced apart from the work platform. An infrared sensor is installed in the gap between the crossbeams and the work platform.

[0016] Compared with existing technologies, this utility model's multi-gripper plate clamping device includes at least three plate clamps. These clamps can be initially positioned on the crossbeam, allowing for dynamic combinations into various clamping modes. This enables the clamps to adapt to the gripping needs of workpieces of different sizes and shapes, increasing structural stability under alternating heavy loads. It achieves single-clamping, reducing fixture changes and avoidance actions, shortening the processing cycle. Furthermore, when multiple clamps work together to hold a workpiece, it effectively improves the structural rigidity of the workpiece, suppressing deformation of long workpieces, thus facilitating better processing of the workpiece in various forms. This effectively solves the problems of low processing efficiency, poor accuracy, and high wear associated with traditional equipment. Moreover, during processing, the clamps can slide along the length of the crossbeam, thereby adjusting the position of the clamped workpiece. This, combined with the drilling device, improves processing flexibility and efficiency.

[0017] It is understandable that, since the CNC six-sided drill of this utility model includes the above-mentioned multi-grip device for sheet metal, it has the technical advantages of a multi-grip device for sheet metal, improving the processing efficiency and accuracy of the equipment, and effectively reducing losses.

[0031] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] This utility model discloses a multi-grip device for sheet metal processing, applicable to the processing of wood, metal, and plastic sheets. After clamping and positioning the sheet metal using the multi-grip device, drilling, grooving, and other processing can be performed on the workpiece. The following is a detailed description of the multi-grip device for sheet metal of this utility model.

[0033] like Figures 1 to 9 As shown, the multi-grip device 100 for sheet metal of this utility model includes a crossbeam 10 and at least three sheet metal grippers 20 slidably disposed on the crossbeam 10. The multiple sheet metal grippers 20 are arranged sequentially along the length of the crossbeam 10. The sheet metal grippers 20 can be initially positioned on the crossbeam 10 and can slide along the length of the crossbeam 10 during processing. Each sheet metal gripper 20 includes a lower clamping seat 21, an upper clamping seat 22, and a cylinder 23. The cylinder 23 is mounted on the lower clamping seat 21, and the upper clamping seat 22 is located above the lower clamping seat 21. The upper clamping seat 22 is mounted on the output end of the cylinder 23, and the cylinder 23 drives the upper clamping seat 22 to move vertically closer to and further away from the lower clamping seat 21. When cylinder 23 drives the upper clamp 22 to move downward and closer to the lower clamp 21, the upper clamp 22 and the lower clamp 21 clamp the workpiece. When cylinder 23 drives the upper clamp 22 to move upward and away from the lower clamp 21, the upper clamp 22 and the lower clamp 21 release the clamp on the workpiece, and the workpiece can be taken out.

[0034] This utility model's multi-grip device 100 for sheet metal includes at least three sheet metal grippers 20. The initial positions of the sheet metal grippers 20 can be adjusted on the crossbeam 10, thereby dynamically combining them into various gripping modes (such as...). Figures 10 to 13 (As shown in the example, multiple clamping modes allow these plate grippers 20 to adapt to the gripping needs of workpieces of different sizes and shapes, increasing structural stability under alternating heavy loads. This enables single-clamping, reducing fixture changes and avoidance actions, shortening the processing cycle. Furthermore, when multiple plate grippers 20 work together to clamp the workpiece, they effectively improve the structural rigidity of the workpiece, suppressing deformation of long workpieces, thus facilitating various forms of workpiece processing. This effectively solves the problems of low processing efficiency, poor accuracy, and high wear associated with traditional equipment. Moreover, the plate grippers 20 can slide along the length of the crossbeam 10 during processing, thereby adjusting the position of the clamped workpiece. This, combined with the drilling device, improves processing flexibility and efficiency.

[0035] In the embodiment provided by this utility model, there are 3 plate clamps 20, the length direction of the crossbeam 10 is the left and right direction, and the 3 plate clamps 20 are arranged sequentially on the crossbeam 10 along the left and right direction.

[0036] The clamping width of the leftmost plate clamp 20 is greater than that of the two plate clamps 20 on the right, but this design is not limited to this structure. At this time, the initial positions of these three plate clamps 20 can be adjusted so that the two plate clamps 20 with smaller clamping widths move away from each other or closer together. When the two plate clamps 20 with smaller clamping widths move closer together, they are equivalent to forming a "plate clamp 20" with a larger clamping width, which is equivalent to the traditional two-clamp mode. One or two clamps can be used to clamp the workpiece. When the two plate clamps 20 with smaller clamping widths move away from each other, they form a three-clamp mode, which can be used to clamp the workpiece with two or three clamps. Thus, different clamping modes can be combined to adapt to the gripping needs of different workpieces.

[0037] The following is a brief introduction on how to use 3 plate clamps 20 to clamp workpieces in different scenarios.

[0038] For machining short workpieces, the two plate clamps 20 on the right side can be used to clamp the workpiece. These two plate clamps 20 are close to each other, and the state is as follows: Figure 10 As shown. For machining long workpieces, the workpiece can be clamped using the leftmost plate clamp 20 and the middle plate clamp 20, with the two plate clamps 20 positioned far apart. The state at this point is as follows. Figure 11 As shown. For machining extra-long workpieces, three plate clamps 20 are used to clamp the workpiece. The two plate clamps 20 on the right side can be relatively close or relatively far apart to provide better support. The state at this time is as follows. Figure 12 and Figure 13 As shown.

[0039] As can be seen above, by setting multiple plate clamps 20 and having them cooperate with each other, it is possible to adapt to workpieces of different lengths and shapes, improve the supporting rigidity of the workpiece to be clamped, and suppress workpiece deformation. It should be noted that the above description uses three plate clamps 20 as an example to illustrate the workpiece clamping method, but it should be understood that in practice, more than three plate clamps 20 can be set, such as four, five, etc. Preferably, the multiple plate clamps 20 slide synchronously in the same direction on the crossbeam 10 during processing to avoid mutual obstruction during sliding.

[0040] like Figures 2 to 13 As shown, the sheet metal clamp 20 also includes a positioning element 24 for positioning the edge of the workpiece. The positioning element 24 is installed on the lower clamp 21 and located between the upper clamp 22 and the lower clamp 21. The upper clamp 22 has a through hole 221 for the positioning element 24 to pass through, and the through hole 221 is positioned directly opposite the positioning element 24. During processing, the workpiece is placed between the upper clamp 22 and the lower clamp 21, with one side of the workpiece positioned by the positioning element 24. As the upper clamp 22 and the lower clamp 21 move closer together to clamp the workpiece, the positioning element 24 passes through the through hole 221.

[0041] like Figures 3 to 9 As shown, the lower clamping seat 21 is equipped with a lower clamping pad 25, which is located on one side of the positioning member 24. The upper clamping seat 22 is equipped with an upper clamping pad 26, which is located directly above the lower clamping pad 25. Both the upper clamping pad 26 and the lower clamping pad 25 have anti-slip grooves. The lower clamping pad 25 and the upper clamping pad 26 provide a cushioning effect. They can be made of soft plastic or rubber to prevent damage to the workpiece. Furthermore, the anti-slip grooves on the lower clamping pad 25 and the upper clamping pad 26 increase the friction when clamping the workpiece, preventing it from loosening.

[0042] like Figures 3 to 9As shown, the lower clamp 21 includes a mounting base 211 and a support base 212. The support base 212 is mounted on the mounting base 211 in a way that allows it to slide up and down. A spring 213 is provided between the support base 212 and the mounting base 211. The spring 213 always has a tendency to push the support base 212 upward. A cylinder 23 is mounted on the support base 212. The piston rod of the cylinder 23 passes through the support base 212 and is connected to the upper clamp 22. The upper clamp 22 is mounted on the mounting base 211 in a way that allows it to slide up and down. Furthermore, the upper clamping seat 22 includes a clamping seat body 222 and a sliding structure 223. The sliding structure 223 is mounted on the mounting seat 211 in a way that allows it to slide up and down. The clamping seat body 222 is connected to the sliding structure 223. The clamping seat body 222 is located directly above the support seat 212. The mounting seat 211 is equipped with a blocking structure 214. The lower end of the sliding structure 223 is equipped with a stop structure 224. The stop structure 224 is located below the blocking structure 214 and directly opposite the blocking structure 214. The piston rod of the cylinder 23 is connected to the clamping seat body 222, and the cylinder 23 drives the clamping seat body 222. Body 222 moves upward and away from support body 212 until the stop structure 224 presses against the blocking structure 214, opening the jaws of plate clamp 20. Cylinder 23 further applies upward force to clamp body 222, driving support body 212 to slide downward and compress spring 213, further opening the jaws of plate clamp 20. This allows support body 212 and clamp body 222 to move away from the upper and lower surfaces of the workpiece, preventing contact with the workpiece when releasing the clamp. At this time, the workpiece will not be misaligned when moving plate clamp 20, and the workpiece will not be taken away or misaligned when resetting plate clamp 20.

[0043] Furthermore, the clamping structure 224 is a set screw, which has an adjustable extension length at the lower end of the sliding structure 223. By adjusting the extension length of the set screw at the lower end of the sliding structure 223, it can be adapted to the clamping needs of workpieces of different thicknesses.

[0044] like Figure 1 , Figure 2 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, a clearance notch 01 is provided on one side of the end of the support body 212 and the clamping body 222. The clearance notch 01 can be used to avoid the area on the workpiece that needs to be processed. Preferably, the area of ​​the clearance notch 01 is not large, and the overall shape is approximately a right-angled notch, but it is not limited to this shape.

[0045] like Figures 1 to 6As shown, a long slide rail 11 arranged along the length of the crossbeam 10 is mounted on the crossbeam 10, and a slider 215 sliding on the long slide rail 11 is mounted on the mounting base 211. The plate clamp 20 also includes an adjusting motor 27, which drives the plate clamp 20 to slide and adjust along the length of the crossbeam 10. The adjusting motor 27, the long slide rail 11, and the slider 215 facilitate the adjustment of the position of the plate clamp 20. Preferably, the adjusting motor 27 can be driven by belt drive, gear and rack drive, or other means to drive the sliding of the plate clamp 20.

[0046] like Figure 1 As shown, the multi-grip device 100 for sheet metal of this utility model can be applied to a CNC six-sided drill. The CNC six-sided drill includes a work platform 200, which is used for placing and supporting workpieces. In addition, the CNC six-sided drill also includes a drill assembly (not shown in the figure). Since the drill assembly is not an improvement made by this utility model, and is well known to those skilled in the art, its structural composition, position, and connection relationship will not be described in detail here. The multi-grip device 100 for sheet metal includes the aforementioned crossbeam 10, which is spaced apart from the work platform 200. An infrared sensor (not shown in the figure) is installed in the gap between the crossbeam 10 and the work platform 200. The infrared sensor can detect the length of the workpiece, whether the workpiece is properly placed on the work platform 200, and whether the workpiece is placed incorrectly.
