Description

Technical Field

[0001] This application belongs to the field of CNC six-sided drilling, and particularly relates to a compact six-sided drilling machine. Background Technology

[0002] The compact six-sided drill press is designed for small to medium-sized machining scenarios. Its core features are a shorter crossbeam and a compact structure, making it suitable for factories with limited space or customized production needs. It uses a single drill pack configuration, with the upper pack handling top machining and the lower pack handling bottom machining. The automatic gripper design provides stable and flexible clamping. During machining, the sheet metal is fixed and moved by the automatic clamp, driven by a mechanical structure along the air-floating table. The compact six-sided drill press achieves its compact structure by shortening the length of the crossbeam and bed. However, this design directly limits the machining range along the X-axis (crossbeam direction). When the sheet metal width exceeds the crossbeam travel distance, even if the drill pack moves to the end of the crossbeam, it cannot cover the sides of the sheet metal, resulting in unmachined sides. Specifically, when the drill pack moves to the end of the crossbeam, its vertical (Z-axis) drill bit can only cover the top of the sheet metal, not the sides, thus limiting the overall machining capacity of the compact six-sided drill press. Therefore, the existing technology needs further improvement. Utility Model Content

[0003] This utility model provides a compact six-sided drill, which solves the problem that the compact six-sided drill has insufficient side processing capability due to the limited crossbeam stroke when processing wide plates.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A compact six-sided drill includes an upper crossbeam with an upper drill pack assembly and a lower crossbeam with a corresponding lower drill pack assembly. A table for supporting the sheet metal to be processed is provided between the upper and lower crossbeams. A clamping device is provided on one side of the table and is located on a movable beam. The clamping device can move along the movable beam to clamp the sheet metal along the length of the table. The movable beam is mounted on a movable frame on one side of the table and can be displaced relative to the movable frame in a direction perpendicular to the side of the table. When processing sheet metal that exceeds the moving range of the drill pack, the movement of the movable beam causes the clamping device to clamp the sheet metal and move it along the crossbeam direction, thus sending the side to be processed into the effective processing range of the drill pack and improving the processing adaptability of the equipment.

[0006] The aforementioned structure, through the horizontal displacement function of the clamping device driven by the moving beam, allows the moving beam to move the plate along the X-axis when the width of the plate exceeds the drill bit's travel, enabling the drill bit to effectively cover the entire width of the plate and solving the pain point of not being able to process the sides of wide plates. The equipment can adapt to more plate sizes without changing its core structure, retaining the space utilization advantage of a compact model while achieving flexible expansion of the processing range through the displacement compensation mechanism of the clamping device, significantly reducing the cost of frequent equipment replacements due to changes in plate specifications. Enterprises can choose whether to enable the moving beam displacement function according to actual needs, avoiding resource waste caused by over-configuration, and achieving a breakthrough in processing capacity and applicable scenarios while maintaining the compactness of the equipment.

[0007] In a preferred embodiment, the upper surface of the moving beam is provided with a guide rail, and the clamping device includes an L-shaped frame. A clamping component is installed at the end of the horizontal section of the L-shaped frame, and a slider is installed on the lower side of the horizontal section. The slider slides in cooperation with the guide rail. The vertical section of the L-shaped frame integrates a drive motor, and a gear is installed at the output end of the motor. The gear meshes with the rack provided on the moving beam, and the rotation of the drive motor can drive the entire clamping device to move along the guide rail.

[0008] In a preferred embodiment, the guide rail has a dovetail-shaped cross-section, and the slider has a dovetail groove, with the two fitting together.

[0009] In a preferred implementation, the clamping member includes an upper clamping plate and a lower clamping plate. The upper clamping plate is movable relative to the lower clamping plate. The clamping member has an initial position. When the clamping member is in the initial position, the upper surface of the lower clamping plate is flush with the table surface and the side of the lower clamping plate near the table surface has an initial gap with the side edge of the table surface. When processing narrow plates, the clamping member maintains the initial position; when processing wide plates, the clamping member moves away from the table surface from the initial position.

[0010] In a preferred implementation, the clamping member can move synchronously with the upper or lower drill bag assembly to shorten the travel distance of the upper / lower drill bag assembly.

[0011] Composite displacement is achieved by the synchronous movement of the clamping device and the drill bag. For example, the processing can be completed by moving the clamping device 20cm laterally and the drill bag 80cm. Compared with the traditional single-axis movement mode of the drill bag, the displacement path is shortened by more than 30%, which significantly improves the processing efficiency and reduces the mechanical wear and energy consumption caused by the high-speed reciprocating motion of the drill bag.

[0012] In a preferred embodiment, the movable frame is equipped with a slide rail parallel to the crossbeam, and the bottom surface of the movable beam is provided with a slide groove. The slide groove and the slide rail are connected in cooperation. A push cylinder is provided on the side of the movable frame near the table surface. Its piston rod is connected to the movable beam. By pushing the piston rod of the cylinder to extend and retract, the movable beam is driven to move along the slide rail direction.

[0013] In a preferred implementation, the movable beam is hollow inside to reduce its weight and lower the moving load.

[0014] In a preferred embodiment, a movable frame is installed at both the front and rear ends of the movable beam, and both ends are equipped with a sliding rail and a sliding groove cooperation structure and a push cylinder for driving. The clamping device can move smoothly in the movable beam area between the two movable frames.

[0015] In a preferred implementation, the push cylinder is connected to a controller to control the extension and retraction distance of the push cylinder piston rod. Attached Figure Description

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] The present invention will now be described with reference to the accompanying drawings.

[0026] The specific solution adopted is as follows:

[0027] like Figure 1-2 As shown, this utility model provides a compact six-sided drill bit, including an upper crossbeam 1 with an upper drill bit assembly and a lower crossbeam 2 with a corresponding lower drill bit assembly. A table 3 for supporting the material to be processed is provided between the upper and lower crossbeams 2. A clamping device 4 is provided on one side of the table 3 and is located on a moving beam 5. The clamping device 4 can move along the moving beam 5 to clamp the material to move along the length direction of the table 3. The moving beam 5 is mounted on a moving frame 6 on one side of the table 3. The moving beam 5 can be displaced relative to the moving frame 6 in a direction perpendicular to the side of the table 3. When processing a material that exceeds the moving range of the drill bit, the moving beam 5 moves to drive the clamping device 4 to clamp the material and move it along the crossbeam direction, sending the side to be processed into the effective processing range of the drill bit, thereby improving the processing adaptability of the equipment.

[0028] The aforementioned structure, through the horizontal displacement function of the moving beam 5 driving the clamping device 4, allows the moving beam 5 to move the plate 0.3 meters along the X-axis when the width of the plate exceeds the drill bit's travel (e.g., drill bit travel 1.2 meters, plate 1.5 meters), effectively covering the entire width of the plate and solving the problem of not being able to process the sides of wide plates. The equipment can adapt to different plate sizes without changing its core structure, retaining the space utilization advantage of a compact model while achieving flexible expansion of the processing range through the displacement compensation mechanism of the clamping device 4, significantly reducing the cost of frequent equipment replacements due to changes in plate specifications. Enterprises can choose whether to enable the displacement function of the moving beam 5 according to actual needs, avoiding resource waste caused by over-configuration, and achieving breakthroughs in processing capacity and applicable scenarios while maintaining the compactness of the equipment.

[0029] As a preferred embodiment of this application, see [link to application]. Figure 2 The upper surface of the moving beam 5 is provided with a guide rail 50. The clamping device 4 includes an L-shaped frame 40. A clamping member 41 is installed at the end of the horizontal extension of the L-shaped frame 40. A slider 400 is installed on the lower side of the horizontal section. The slider 400 slides in cooperation with the guide rail 50. The vertical section of the L-shaped frame 40 integrates a drive motor 42. A gear 420 is installed at the output end of the motor. The gear 420 meshes with the rack of the moving beam 5. The rotation of the drive motor 42 can drive the entire clamping device 4 to move along the guide rail 50. Through the meshing transmission between the gear 420 and the rack of the moving beam 5, the rotation is transmitted. The motion is converted into linear motion. Compared with traditional belt or chain drives, the gear 420 rack structure has the characteristics of strong impact resistance and high positioning accuracy. Combined with the linear guidance of the slider 400 and the guide rail 50, it meets the requirements of high-precision machining. The core components such as the drive motor 42, gear 420, and clamping device 41 are all integrated into the L-shaped frame 40 to form an independent motion unit. When a clamping device 4 fails, it can be quickly disassembled and replaced without the need for overall shutdown for maintenance. At the same time, the standardized design of the gear 420 rack reduces the cost of spare parts and the difficulty of maintenance.

[0030] Furthermore, the cross-section of the guide rail 50 is dovetail-shaped, and the slider 400 has a dovetail groove. The two are connected to each other. The trapezoidal cross-section design of the dovetail groove makes the slider 400 and the guide rail 50 form a wedge-shaped self-locking effect in the vertical direction, thereby preventing vertical swaying or disengagement due to gaps. The inclined surfaces on both sides of the dovetail groove form a rigid guide in the horizontal direction, so that the clamping device 4 always remains in a horizontal state, avoiding misalignment or chipping of the plate processing surface caused by the tilt of the clamping part 41 during the clamping process, and significantly improving the verticality consistency of drilling, grooving and other processes.

[0031] In a preferred embodiment of this application, the clamping member 41 includes an upper clamping plate and a lower clamping plate. The upper clamping plate is movable relative to the lower clamping plate. The clamping member 41 has an initial position. When the clamping member 41 is in the initial position, the upper surface of the lower clamping plate is flush with the table surface 3, and there is an initial gap between the side of the lower clamping plate near the table surface 3 and the side edge of the table surface 3. When processing narrow plates, the clamping member 41 maintains the initial position; when processing wide plates, the clamping member 41 moves away from the table surface 3 from the initial position. Furthermore, the clamping member 41 can move synchronously with the upper drill bag assembly or the lower drill bag assembly to shorten the travel distance of the upper / lower drill bag assembly.

[0032] Specifically, when the clamping member 41 is in the initial position, the upper surface of the lower clamping plate is flush with the table surface 3 and there is a small gap on the side. At this time, the lateral drilling tool can be vertically lowered to the side surface of the board for conventional drilling or grooving without additional adjustment of the clamping device 4, maintaining the accuracy and efficiency of the traditional processing mode. When processing wide boards, the clamping member 41 can move as a whole away from the table surface 3, so that the lateral drilling tool can be lowered to the side of the board for processing, rather than being limited to the upper surface. This is especially suitable for special process requirements of irregular boards or furniture edges.

[0033] Furthermore, the processing efficiency of wide sheet metal spans is improved. For processing points with large spans on wide sheet metal, such as 100cm, composite displacement is achieved by taking the initial processing point as the origin and synchronously moving the clamping device 4 and the drill bag. For example, the processing can be completed by moving the clamping device 4 laterally by 20cm and the drill bag by 80cm. Compared with the traditional single-axis movement mode of the drill bag, the displacement path is shortened by more than 30%, which significantly improves the processing efficiency. At the same time, it reduces the mechanical wear and energy consumption caused by the high-speed reciprocating motion of the drill bag. The drive systems of both need to be speed-synchronized, that is, by using a numerical control system (CNC) or motion controller, the clamping device 4 and the drill bag can run at an appropriate speed ratio.

[0034] In a preferred embodiment of this application, the movable frame 6 is equipped with a slide rail 60 parallel to the crossbeam, and the bottom of the movable beam 5 is provided with a groove 51 matching the slide rail 60. Linear guidance is achieved through the nesting of the slide rail 60 and the groove 51. A push cylinder 7 is installed on the side of the movable frame 6 near the table 3, and its piston rod is rigidly connected to the end of the movable beam 5. When the piston rod of the cylinder extends or retracts, it drives the movable beam 5 to make linear displacement along the slide rail 60 through mechanical push-pull action. The rapid response characteristics of the cylinder are utilized to achieve precise positioning and efficient driving of the movable beam 5. Alternatively, a servo motor-driven ball screw is used instead of the cylinder. The ball screw cooperates with the nut pair at the bottom of the movable beam 5 to convert the rotational motion of the motor into the linear motion of the movable beam 5. The motor drives the ball screw to rotate through a reducer or directly to achieve displacement control.

[0035] Furthermore, movable frames 6 are installed at the front and rear ends of the movable beam 5, and both ends are equipped with a sliding rail 60 and a sliding groove 51 cooperation structure and a push cylinder 7 for driving. The clamping device 4 can move smoothly in the area of ​​the movable beam 5 between the two movable frames 6.

[0036] Furthermore, the push cylinder 7 is connected to a controller to control the extension and retraction distance of the piston rod of the push cylinder 7. The controller establishes communication with the electromagnetic proportional valve or servo valve of the cylinder through a digital signal interface. When the operator inputs a target displacement value (such as 20mm) into the human-machine interface of the controller, the internal algorithm of the controller converts the displacement value into the corresponding cylinder stroke parameters, thereby realizing the control and adjustment of the extension distance.

[0037] See Figure 1 The movable beam 5 is hollow inside to reduce its own weight and reduce the moving load.

[0038] After the moving beam 5 adopts an internal hollow structure design, the weight is reduced, which directly reduces the load requirements of the pushing cylinder 7 or the drive motor 42. Especially in high-frequency reciprocating motion scenarios, it can quickly achieve pushing, thereby reducing equipment energy consumption and improving processing efficiency.

[0039] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0040] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
