Description

Technical Field

[0001] This utility model relates to the field of wood or similar material processing technology, and in particular to a drilling assembly and a board processing device. Background Technology

[0002] Sheet metal refers to flat, rectangular panels made into standard sizes for furniture and decoration. It is primarily used in the furniture and decoration industry for components of furniture, wardrobes, cabinets, and handicrafts. It also refers to metal sheets produced through forging, rolling, or casting. Based on thickness, sheets can be classified as thin, medium, thick, and extra-thick. In actual production, they are typically made into standard-sized flat, rectangular building material panels. As a lightweight building material, sheet metal possesses high strength, light weight, fire resistance, environmental friendliness, good decorative effect, and ease of processing. These characteristics allow it to be used in interior ceilings, lightweight partitions, and decorative finishes, making it a promising new type of building decoration material that is energy-efficient, environmentally friendly, and has the greatest development potential in the building decoration industry.

[0003] Existing sheet metal processing equipment uses a drilling assembly that is slidably connected to a guide rail. The guide rail extends in a direction perpendicular to the direction of sheet metal movement. Two guide rails are fixed at intervals above and below the sheet metal support surface. The drilling assembly connected to the upper guide rail is the upper drilling assembly, which is used to drill holes on the upper surface of the sheet metal. The drilling assembly connected to the lower guide rail is the lower drilling assembly, which is used to drill holes on the lower surface of the sheet metal. During production, the board is driven to move. When the drilling area of ​​the board and the drilling assembly are on the same vertical plane, the board stops moving. The drilling assembly then slides along the guide rail to different positions to drill different drilling areas on the same vertical plane. When the drilling area on the upper surface of the board corresponds to the upper drilling assembly, the drilling area on the lower surface often does not correspond to the lower drilling assembly, or vice versa. Therefore, each pause of the board often only allows drilling on either the upper or lower surface, i.e., drilling on the upper and lower surfaces alternates. This not only results in low drilling efficiency, leading to low overall processing efficiency and increased processing costs, but also causes positioning errors due to the numerous board movements.

[0004] For example, Chinese utility model patent CN220113525U, entitled "A Six-Sided Drilling and Milling Machine for Wood Boards with a Dual Spindle and Tool Magazine," includes an upper drilling assembly comprising a translational servo motor, a lifting servo motor, and an automatic tool changer spindle, wherein the translational and lifting servo motors drive the automatic tool changer spindle to move along directions A and B, respectively; a tool magazine assembly comprising a tool magazine cylinder, a tool magazine cylinder parallel to the tool magazine cylinder, and a tool holder, wherein the tool magazine cylinder is mounted on a board surface, and the tool magazine cylinder drives the board surface and the tool holder to move along direction C; a lower drilling assembly comprising a lower spindle and a lower spindle parallel to the lower spindle, and a lower milling cutter cylinder and a lower milling cutter cylinder corresponding to the lower spindle and the lower spindle, wherein the lower milling cutter cylinder and the lower milling cutter cylinder are connected to the lower spindle and the lower spindle via a set of C-frames; and a support.

[0005] Therefore, how to eliminate the impact of alternating drilling on the upper and lower surfaces of the board on the overall processing efficiency of the board is a technical problem that technicians need to solve. Utility Model Content

[0081] This utility model provides a drilling assembly and a sheet metal processing device to solve the technical problem that the existing sheet metal processing device uses an alternating drilling method on the upper and lower surfaces of the sheet metal, which reduces the overall processing efficiency.

[0085] Existing sheet metal processing equipment uses a drilling assembly that is slidably connected to a guide rail. The guide rail extends in a direction perpendicular to the direction of sheet metal movement. Two guide rails are fixed at intervals above and below the sheet metal support surface. The drilling assembly connected to the upper guide rail is the upper drilling assembly, which is used to drill holes on the upper surface of the sheet metal. The drilling assembly connected to the lower guide rail is the lower drilling assembly, which is used to drill holes on the lower surface of the sheet metal. During production, the board is driven to move. When the drilling area of ​​the board and the drilling assembly are on the same vertical plane, the board stops moving. The drilling assembly then slides along the guide rail to different positions to drill different drilling areas on the same vertical plane. When the drilling area on the upper surface of the board corresponds to the upper drilling assembly, the drilling area on the lower surface often does not correspond to the lower drilling assembly, or vice versa. Therefore, each pause of the board often only allows drilling on either the upper or lower surface, i.e., drilling on the upper and lower surfaces alternates. This not only results in low drilling efficiency, leading to low overall processing efficiency and increased processing costs, but also causes positioning errors due to the numerous board movements. Example

[0086] Please see Figure 1-6 The drilling assembly provided in this embodiment of the present invention includes:

[0087] The system comprises a first drive unit 11, a second drive unit 12, a third drive unit 13, a drilling unit 171, and a support unit. The first drive unit 11 has a first driving direction; the second drive unit 12 has a second driving direction; and the third drive unit 13 has a third driving direction. The first, second, and third driving directions are perpendicular to each other. The support unit includes a first support member 151 and a second support member 162. The driving end of the first drive unit 11 is connected to the first support member 151. The second drive unit 12 is mounted on the first support member 151, and its driving end is connected to the second support member 162. The third drive unit 13 is mounted on the second support member 162, and its driving end is connected to the drilling unit 171.

[0088] It should be noted that:

[0089] The first drive unit 11 is used to drive the drilling unit 171 to move along the first direction. Its specific shape and structure are not limited here. It can be any device that can provide linear drive, such as a linear motor, cylinder, etc., or it can be a combination of a power source and transmission structure that can provide linear drive, such as a rotary motor with a gear on the rotating shaft and a rack combination.

[0090] The second drive unit 12 is used to drive the drilling unit 171 to move in the second direction. Its specific shape and structure are not limited here. It can be any device that can provide linear drive, such as a linear motor, cylinder, etc., or it can be a combination of a power source and transmission structure that can provide linear drive, such as a rotary motor with a gear on the rotating shaft and a rack combination.

[0091] The third drive unit 13 is used to drive the drilling unit 171 to move along a third direction. Its specific shape and structure are not limited here. It can be any device that can provide linear drive, such as a linear motor, cylinder, etc., or it can be a combination of a power source and transmission structure that can provide linear drive, such as a rotary motor with a gear on the rotating shaft and a rack combination.

[0092] The drilling unit 171 is used to drill holes in the plate 3. It can be any kind of automatic drilling device in the prior art, and the specific device can be selected according to the actual situation.

[0093] The support unit provides support for other units in the drilling assembly, connects the various units together, and ensures that the movement of each unit does not interfere with each other and is stable. Specifically, the first support member 151 connects the second drive unit 12 to the first drive unit 11 and provides support for the second drive unit 12. Thus, driven by the first drive unit 11, the first support member 151 and the second drive unit 12 move together along a first direction. The second support member 162 connects the second drive unit 12 to the third drive unit 13 and provides support for the third drive unit 13. Thus, driven by the second drive unit 12, the second support member 162 and the third drive unit 13 move together along a second direction. Driven by the third drive unit 13, the drilling unit 171 moves along a third direction, thereby achieving the driving of the drilling unit 171 along the first, second, and third directions.

[0094] The beneficial effects of this embodiment include:

[0095] 1. The first drive unit 11 drives the drilling unit 171 to move along the first direction, the second drive unit 12 drives the drilling unit 171 to move along the second direction, and the third drive unit 13 drives the drilling unit 171 to move along the third direction. By setting any one of the first, second, and third directions to be parallel to the moving direction of the plate 3, the drilling unit 171 can have translational freedom on a plane parallel to the surface of the plate 3. After the plate 3 stops moving, the drilling unit 171 can actively move to the position corresponding to the drilling area to perform drilling operations. In this way, by using at least one drilling component as an upper drilling component (or a lower drilling component) in conjunction with a conventional lower drilling component (or an upper drilling component) to drill the plate 3, drilling operations on both surfaces of the plate 3 can be performed simultaneously, improving drilling efficiency and thus improving the overall processing efficiency of the plate 3 and reducing costs.

[0096] 2. Since the drilling unit 171 can move in the direction of movement of the plate 3, the number of times the plate 3 moves is reduced, thus reducing the probability of positioning deviation.

[0097] Optimization of the drilling assembly: The support unit further includes a third support member 163 extending along the second direction; the third support member 163 is slidably connected to the first support member 151; the first support member 151 can slide along the first direction. The third support member 163 provides support for the first support member 151, allowing the first support member 151 to slide along the first direction under the drive of the first drive unit 11. Compared to providing support for the first support member 151 through the first drive unit 11, this reduces the load on the first drive unit 11 and provides sliding stability for the first support member 151.

[0098] Optimization of the portion of the driving drilling unit 171 that moves along the first direction: The third support member 163 is a square column structure; the first support member 151 includes a first plate 1511 and a second plate 1512 connected vertically; the second plate 1512 is parallel to the plane containing the first and second directions, and the second driving unit 12 is disposed on the second plate 1512; the first driving unit 11 includes a first rotary motor 111 and a first gear 112; the first gear 112 is sleeved on the rotation shaft of the first rotary motor 111; the first surface of the third support member 163 is provided with a first rack 1632 extending along the first direction; the first rotary motor 111 is fixed to the first plate 1511; the rotation shaft of the first rotary motor 111 passes through the first plate 1511 and meshes with the first rack 1632 through the first gear 112; the first plate 1511 and the third support member 163 are slidably connected. The first rotary motor 111 drives the first gear 112 to rotate. The rotating first gear 112 continuously meshes with the first rack 1632, thereby driving the first support member 151 to move along the first direction, and in turn driving the drilling unit 171 connected to the first support member 151 to move along the first direction. The drilling unit 171 is driven to move along the first direction by the cooperation of the gear and rack, which has higher driving stability.

[0099] Further optimization of the portion of the driving drilling unit 171 that moves along the first direction: To improve the movement stability of the first support member 151 in the first direction, a first guide rail 1631 extending along the first direction is provided on the second surface of the third support member 163, with the first surface adjacent to the second surface; the first support member 151 is also provided with a first slider 1513 adapted to the first guide rail 1631; the first slider 1513 is connected to the first guide rail 1631. Through the cooperation of the first guide rail 1631 and the first slider 1513, the first support member 151 is guided and supported to move along the first direction, thereby improving movement stability.

[0100] For example: Figure 1The orientation shown is explained below. The third support member 163 is a crossbeam of a gantry structure. A first rack 1632 extending in the front-back direction (first direction) is provided on the right side of the upper surface (first surface) of the crossbeam.

The two first sliders 1513 are arranged at intervals along the first direction. Two first sliders 1513 are connected to the first guide rail 1631; the first drive unit 11 includes a first rotary motor 111 and a first gear 112; the first gear 112 is sleeved on the rotating shaft of the first rotary motor 111, the main body of the first rotary motor 111 is fixed on the upper surface of the first plate 1511, and its rotating shaft passes through the central area of ​​the second plate 1512 in the vertical direction and then meshes with the left tooth surface of the first rack 1632 through the first gear 112 on it. When the first rotary motor 111 rotates, it drives the first support member 151 to move in the front-back direction. The lower left surface of the second plate 1512 is provided with four first sliders 1513 that are adapted to the first guide rail 1631. The four first sliders 1513 are arranged in two rows and two columns, with the two upper sliders 1513 connected to the upper first guide rail 1631, and the two lower sliders 1513 connected to the lower first guide rail 1631. The front and rear right surfaces of the second plate 1512 are each provided with a third guide rail 151 extending in the vertical direction (second direction). 4. The left surface of the third plate 1621 is provided with four third sliders 1624 arranged in two rows and two columns, which are adapted to the third guide rail 1514. The two third sliders 1624 located on the front side are connected to the third guide rail 1514 on the front side, and the two third sliders 1624 located on the rear side are connected to the third guide rail 1514 on the rear side. The second drive unit 12 is a third rotary motor fixed on the upper side of the right surface of the second plate 1512. Its rotation shaft is connected to the left surface of the third plate 1621 through a coupling 121 and a ball screw 122 to drive the third plate 1621 to move in the up and down direction.

[0101] Optimization of the portion of the driving drilling unit 171 that moves along a third direction: The support unit further includes a flat fourth support member 164; the second support member 162 includes a vertically connected third flat plate 1621 and a fourth flat plate 1622; the third flat plate 1621 is parallel to the plane containing the first and second directions, and the fourth flat plate 1622 is parallel to the plane containing the second and third directions; the third driving unit 13 includes a second rotary motor 131 and a second gear 132; the second gear 132 is sleeved on the rotation shaft of the second rotary motor 131; The fourth plate 1622 is provided with a second guide rail 1623 extending in a third direction; the fourth support member 164 is provided with a second slider 1641 and a second rack 1642 extending in a third direction; the second slider 1641 is slidably connected to the second guide rail 1623; the second rotary motor 131 is fixed to the fourth plate 1622; the rotation shaft of the second rotary motor 131 passes through the fourth plate 1622 and meshes with the second rack 1642 through the second gear 132; the drilling unit 171 is fixed to the fourth support member 164. The second rotary motor 131 drives the second gear 132 to rotate, and the second gear 132 continuously meshes with the second rack 1642, thereby driving the fourth support member 164 to move in a third direction, and then driving the drilling unit 171 on the third support member 163 to move in a third direction. The use of gear and rack to drive the drilling unit 171 to move in a third direction improves the stability of the drive, and the use of slider and guide rail to guide the movement of the fourth support member 164 improves the stability of the movement.

[0102] For example, with Figure 4The orientation shown is explained as follows: the third plate 1621, the fourth plate 1622, and the fourth support member 164 are all vertical plates. The front and rear surfaces of the third plate 1621 are the largest surfaces, as are the left and right surfaces of the fourth plate 1622 and the fourth support member 164. The rear surface of the fourth plate 1622 is perpendicularly connected to the left side of the front surface of the third plate 1621. To increase the support strength of the fourth plate 1622, a connecting plate that fits against the front surface of the third plate 1621 connects the fourth plate 1622 to the third plate 1621. The body of the second rotary motor 131 is fixed in the middle area of ​​the left and right surface of the fourth plate 1622. Its rotation axis passes through the fourth plate 1622 in the left-right direction (first direction) and then engages with the second gear 1. 32. The upper and lower sides of the right surface of the fourth plate 1622 are provided with a second guide rail 1623 extending in the front-back direction (third direction); the left surface of the fourth support member 164 is provided with four second sliders 1641 arranged in two rows and two columns, which are adapted to the second guide rails 1623. The two second sliders 1641 on the upper side are connected to the second guide rail 1623 on the upper side, and the two second sliders 1641 on the lower side are connected to the second guide rail 1623 on the lower side; a second rack 1642 extending in the front-back direction is provided in the middle area of ​​the left surface of the fourth support member 164. The lower surface of the second rack 1642 is the tooth surface that meshes with the second gear 132; the drilling unit 171 is fixed to the right surface of the fourth support member 164.

[0103] Thus, when the drilling unit 171 reaches the position corresponding to the drilling area on the board surface under the drive of the first drive unit 11 and the third drive unit 13, that is, when the axis of rotation of the drilling unit 171 is collinear with the axis of the drilling area, the second support member 162 is first driven by the second drive unit 12 to quickly approach the board surface of the board 3, thereby driving the drilling unit 171 to quickly approach the target drilling area. When the distance between the drilling unit 171 and the target drilling area is small enough, the second drive unit 12 stops driving and starts the drilling unit 171, thereby driving the drilling unit 171 to approach the target drilling area and realize drilling.

[0104] Further optimization: To improve the practicality of the drilling assembly, K milling units 172 and K fourth drive units 14 with the driving direction in the second direction are added to the drilling assembly. The milling units 172 are used to groove the plate 3. The rotation axis of the milling units 172 extends along the second direction, and K is an integer greater than or equal to 1. The fourth drive units 14 are fixed to the third support member 163. Each of the fourth drive units 14 is connected to one of the milling units 172, that is, each milling unit 172 can move along the second direction under the drive of the fourth drive unit 14. After entering the working area of ​​the milling unit 172 in the grooving area of ​​the board 3, the first drive unit 11 drives the milling unit 172 to move to the corresponding position. Then, the second drive unit 12 drives the milling unit 172 to quickly approach the surface of the board 3. When the distance between the milling unit 172 and the board surface is less than a certain level, the second drive unit 12 stops driving. Then, the fourth drive unit 14 drives the milling unit 172 to continue approaching the board surface to groove the board 3. It should be understood that grooves extending along the first direction are grooved by the first drive unit 11 driving the milling unit 172 to move, while grooves extending along a third direction are grooved by driving the board 3 to move along the third direction.

[0105] For example: Figure 4 The diagram illustrates that, to improve grooving speed, two grooving units are arranged at intervals along the first direction. The right side of the front surface of the third plate 1621 has two fourth guide rails 1625 extending vertically (the second direction). Each milling unit 172 has two fourth sliders 1721 on its rear side that are compatible with the fourth guide rails 1625. The fourth sliders 1721 are connected to the fourth guide rails 1625. The fourth drive unit 14 is a linear cylinder fixed to the upper end of the third plate 1621, and its drive end is fixedly connected to the milling unit 172. The milling cutters equipped in the two milling units 172 have different diameters. In this embodiment, the diameter of the milling cutter in the left milling unit 172 is 6mm, and the diameter of the milling cutter in the right milling unit 172 is 10mm. Thus, the appropriate milling unit 172 can be selected for grooving according to different groove widths, eliminating the need to change the milling cutter and improving grooving efficiency. Example

[0106] Please see Figure 1-8 The sheet metal processing device provided in this embodiment of the utility model includes:

[0107] N drilling components provided in any of the embodiments, where N is an integer greater than or equal to 1.

[0108] For example: Figure 7 , 8As shown, for ease of description and understanding, the length direction of plate 3 is defined as the front-back direction, the width direction of plate 3 is defined as the left-right direction, and the direction perpendicular to the largest surface of plate 3 is defined as the up-down direction. Two grippers 21 that can slide in the front-back direction are provided on the right side of the support surface of plate 3. The grippers 21 drive plate 3 to move back and forth. A drilling assembly is suspended above the support surface of plate 3 via a gantry structure. The driving direction of the first drive unit 11 is perpendicular to the moving direction of plate 3, i.e., the first direction is perpendicular to the moving direction of plate 3. An existing lower drilling assembly is suspended below the support surface of plate 3 via a square beam 22. In this assembly, the part of the lower drilling component used for drilling can only move left and right and up and down. Thus, the gripper 21 only needs to move the plate 3 according to the drilling area on the lower surface of the plate 3. When the drilling area on the lower surface of the plate 3 moves to the vertical plane where the axis of the drill bit of the lower drilling component is located, the movement can be stopped and the lower drilling component performs the lower drilling operation. At the same time, the drilling unit 171 in the drilling component actively moves to above the drilling area on the upper surface under the drive of the first drive unit 11 and the third drive unit 13, and then approaches the upper surface under the drive of the second drive unit 12 to perform the upper drilling operation. The simultaneous upper drilling operation and lower drilling operation can improve the drilling efficiency. In addition, to prevent the plate 3 from shifting under the action of the upper and lower drill bits, a support platform is set on the support surface of the plate 3. The support platform corresponds to the coverage area of ​​the drilling unit 171, so as to ensure that when the upper drill bit drills at any position it can reach, the support platform can provide support force to the plate 3 to counteract the downward thrust of the upper drill bit on the plate 3. At the same time, a vertically retractable pressure plate assembly (not shown in the figure) is set on the lower surface of the crossbeam (third support member 163) of the gantry structure. The pressure plate assembly applies pressure to the upper surface of the plate 3 to counteract the upward thrust of the lower drill bit on the plate 3. In this way, it can be ensured that the plate 3 is under balanced force during the drilling process and will not shift.

[0109] Optimized: When N=2, one drilling assembly is used to drill holes on the first surface of the board 3, and another drilling assembly is used to drill holes on the second surface of the board 3. The first surface and the second surface can be the two surfaces with the largest area on the board 3, or a largest surface and a side surface.
