Technical Field

[0001] This utility model relates to the technical field of sheet metal parts processing equipment, and in particular to equipment for drilling, tapping and countersinking sheet metal in the sheet metal industry. Background Technology

[0002] Currently, most sheet metal parts require secondary processing after being cut by CNC turret punch presses and laser cutting machines, such as drilling, tapping, and countersinking. This secondary processing is generally carried out using equipment such as electric drills, bench drills, and tapping machines. During processing, operators often manually support the workpiece for positioning, which is inefficient, labor-intensive, and costly, and is prone to missing holes and misalignment. Especially when processing large-sized workpieces, positioning is difficult, which can easily cause deformation and misalignment of the sheet metal, and poses a high risk to personal safety. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic drilling, tapping, and countersinking processing equipment for sheet metal, which can conveniently and quickly clamp and position sheet metal of different sizes, especially large-sized sheet metal, to achieve fully automatic composite processing of drilling, tapping, and countersinking; reduce the labor intensity of workers, improve processing efficiency, and eliminate the problems of misalignment and missing holes in secondary processing of sheet metal parts.

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

[0006] The machine bed includes a worktable and a servo spindle head positioned above the worktable; the worktable supports the sheet metal to be processed, and the servo spindle head carries a machining tool and presses down to process the sheet metal; and

[0007] A mobile platform is mounted on the bed and supported by a sliding system that guides the movement of the mobile platform; the mobile platform is located on the side of the worktable and connects to the worktable for lateral extension, and the mobile platform can feed materials longitudinally relative to the worktable.

[0008] A crossbeam is mounted on the bed and moves longitudinally synchronously with the moving platform. A straight tool magazine is provided on the crossbeam. The straight tool magazine extends laterally relative to the worktable and is positioned higher than the moving platform in three-dimensional space. The straight tool magazine can also move laterally relative to the crossbeam. The straight tool magazine provides machining tools to the servo spindle head.

[0009] A floating support mechanism is installed on the bed and located below the worktable. The floating support mechanism has a support mold that can be raised and lowered. The support mold supports the lower side of the plate through a clearance hole preset at a corresponding position on the worktable, so as to assist the servo spindle head in pressing down to process the plate.

[0010] The above-mentioned solution further includes a sliding system comprising a slide block and a first motor lead screw structure. The slide block is mounted on the bed via a linear slide rail, and the first motor lead screw structure is positioned on the bed and pulls the slide block to reciprocate longitudinally.

[0011] The above-mentioned solution is further described in that the bed is constructed by combining a spindle bed and a feeding bed, the worktable spans the spindle bed and the feeding bed, the servo spindle head and the floating support mechanism are mounted on the spindle bed, and the moving platform, the sliding system and the crossbeam are mounted on the feeding bed.

[0012] A further aspect of the above scheme is that the crossbeam is fixed on the slide block, and a slide plate is provided on the crossbeam, which carries the straight-line tool magazine to move laterally relative to the crossbeam.

[0014] The above scheme further includes a floating support mechanism, which also includes a mounting bracket and a servo electric cylinder. The mounting bracket is fixedly connected to the spindle bed. The servo electric cylinder is mounted on the mounting bracket and has a first support rod that can protrude from the upper end of the mounting bracket. Two support molds are arranged at intervals on the upper end of the mounting bracket. The two support molds are matched with the first support rod by automatically switching positions, so that the servo electric cylinder drives the first support rod to extend upward, and then the first support rod lifts the corresponding support mold, so that the support mold establishes a supporting posture and supports the lower side of the plate.

[0015] The above scheme is further described as follows: the cross-section of the slide is L-shaped, the slide is attached to the upper and front sides of the crossbeam, and the slide is connected to the crossbeam through a linear guide rail. A second motor screw structure is also provided on the upper side of the crossbeam, which drives the slide to move laterally and reciprocally.

[0033] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.

[0034] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used 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.

[0035] See Figures 1-9The diagram shown is a preferred embodiment of this utility model. This utility model relates to an automatic drilling, tapping, and countersinking processing equipment for sheet metal, belonging to the field of CNC equipment for automated sheet metal processing. It is used for fully automatic drilling, tapping, and countersinking composite processing of sheet metal, reducing labor intensity, improving efficiency, and eliminating problems such as missed holes and misalignment in sheet metal parts processing. This automatic drilling, tapping, and countersinking processing equipment for sheet metal includes: a bed 1, a moving platform 2, a crossbeam 3, a floating support mechanism 5, and a corresponding control system. The bed 1 is equipped with a worktable 11 and a servo spindle head 12 located above the worktable. In this embodiment, the bed 1 is constructed by combining a spindle bed 13 and a feeding bed 14 longitudinally. The spindle bed 13 is a C-shaped structure with a longitudinal concave portion. The C-shaped opening of the spindle bed 13 faces the feeding bed 14. The worktable 11 is in the form of a flat plate. One end of the worktable 11 extends into the longitudinal concave portion of the spindle bed 13, and the other end is mounted on the feeding bed 14, so that the worktable 11 spans the spindle bed 13 and the feeding bed 14 to form a relatively fixed whole. At the same time, the lower side of the worktable 11 is suspended from the feeding bed 14 to leave a clearance for subsequent installation and implementation of other components. The machine bed 1 is divided into two parts: the spindle bed 13 and the feed bed 14. This facilitates machining, reduces deformation, increases precision, and lowers machining costs. It also perfectly solves the equipment transportation problem. The spindle bed 13 and feed bed 14 are simply assembled together during use, improving the equipment's flexibility. The worktable 11 supports the sheet metal to be machined. The servo spindle head 12 is mounted on the spindle bed 13 and vertically arranged at the C-shaped opening of the spindle bed 13. The servo spindle head 12 carries the machining tool and presses down to machine the sheet metal.

[0036] The mobile platform 2 is mounted on the bed 1 and supported by a sliding system that guides its movement. In this embodiment, the sliding system includes a slide block 61 and a first motor lead screw structure 62. The slide block 61 is mounted on the feeding bed 14 via a linear guide rail. The first motor lead screw structure 62 is positioned on the bed 1 and pulls the slide block 61 to reciprocate longitudinally. The mobile platform 2 lies flat on the slide block 61 and is located on the side of the worktable 11, extending laterally. The mobile platform 2 can feed materials longitudinally relative to the worktable. By increasing the bearing surface and enabling movable feeding, the mobile platform 2 achieves automatic positioning and conveying of large sheet metal workpieces, reducing the labor intensity of workers. In this embodiment, the slide 61 is horizontally U-shaped and is mounted on the feeding bed 14 via symmetrical linear slide rails. The slide 61 moves under the worktable 11. The first motor lead screw structure 62 is also conveniently hidden under the worktable 11 and mounted on the feeding bed 14. The first motor lead screw structure 62 drives the slide 61 to reciprocate by pushing and pulling. The moving platform 2 extends symmetrically on the left and right sides of the worktable 11, increasing the load-bearing area and ensuring structural stability and reliability. A positioning component 21 is provided on the moving platform 2, which positions the plate by abutting against it. Figure 4As shown, the positioning component 21 includes a mounting base and a positioning cylinder. The mounting base is mounted on the moving platform 2, and the positioning cylinder is mounted on the mounting base. The piston rod of the positioning cylinder rises and protrudes onto the moving platform 2 to align with the material, thereby achieving rapid positioning of the material. There may be one or more positioning components 21, which can be distributed according to actual needs to accommodate positioning work of materials of different sizes. Steps may also be appropriately provided on the corresponding edges of the moving platform 2 to facilitate positioning and other operations.

[0037] The crossbeam 3 is mounted on the bed 1 and moves longitudinally synchronously with the moving platform 2. In this embodiment, the crossbeam 3 is also mounted on the feeding bed 14 and located behind the moving platform 2. The crossbeam 3 is equipped with a linear tool magazine 4, which extends laterally relative to the worktable. The linear tool magazine 4 is positioned higher than the moving platform 2 in three-dimensional space. At the same time, the linear tool magazine 4 can move laterally relative to the crossbeam 3 so that it can provide machining tools to the servo spindle head 12 to meet different machining needs and realize fully automatic drilling, tapping, and countersinking composite machining of sheet metal.

[0038] The floating support mechanism 5 is mounted on the bed 1 and located below the worktable. The floating support mechanism 5 has a support mold 51 that can move up and down. This support mold 51 supports the lower side of the plate material through a pre-set clearance hole 111 at a corresponding position on the worktable, assisting the servo spindle head 12 in pressing down on the plate material for machining, thereby ensuring that the plate material does not deform. The floating support mechanism 5 is suitable for supporting plates of different thicknesses, ensuring a stable distance between the plate material and the machining tool during machining, guaranteeing that the drilling, tapping, and countersinking depths are consistent with the set values. It completely solves the problems of plate material deformation and uncontrollable machining depth during drilling and tapping, especially in countersinking, where it can precisely control the countersinking depth, meeting the high-precision machining requirements of drilling and tapping machining centers.

[0039] Figure 1 , 5As shown in Figure 6, in this embodiment, the crossbeam 3 is fixed on the slide 61, and a slide 31 is provided on the crossbeam 3. The slide 31 carries the straight-line tool magazine 4 and moves laterally relative to the crossbeam 3. A clamp 32 is also assembled on the slide 31. The clamp 32 is used to clamp the plate and move it laterally relative to the slide or move longitudinally with the moving platform 2. The clamp 32 includes an upper clamp body, a lower clamp body, a clamping cylinder, and a pin. The clamping cylinder is fixedly installed on the upper clamp body, the lower clamp body is connected to the upper clamp body through the pin, and the piston of the clamping cylinder is connected to the lower clamp body. The clamp is tensioned by the extension and retraction of the clamping cylinder. The clamp is installed on the slide, and the movement of the slide realizes the lateral movement of the plate clamped by the clamp. The slide 31 has an L-shaped cross-section and is attached to the upper and front sides of the crossbeam 3. The slide 31 is connected to the crossbeam 3 via a linear guide rail. A second motor screw structure 33 is also provided on the upper side of the crossbeam 3, which drives the slide 31 to move laterally and reciprocally. The straight tool magazine 4 is located on the front side of the slide 31. There are two clamps 32, which are distributed at both ends of the straight tool magazine 4. The structure is compact and small in size.

[0040] Figure 2 , 8 As shown in Figure 9, the floating support mechanism 5 further includes a mounting bracket 52 and a servo electric cylinder 53. The mounting bracket 52 is fixedly connected to the spindle bed 13. The servo electric cylinder 53 is mounted on the mounting bracket 52 and has a first support rod 531 that can protrude from the upper end of the mounting bracket. Two support molds 51 are arranged at intervals on the upper end of the mounting bracket. The two support molds 51 automatically switch positions to align with the first support rod 531, so that the servo electric cylinder 53 drives the first support rod 531 to extend upward, thereby the first support rod 531 lifts the corresponding support mold 51, so that the support mold 51 establishes a supporting posture to support the lower side of the plate. The switching support of the two support molds 51 can meet the needs of drilling and tapping hole diameters of different sizes.

[0041] The floating support mechanism 5 is located on one end of the spindle bed 13 near the feeding bed 14, and the floating support mechanism 5 and the servo spindle head 12 are in a vertically opposite relationship; the two support molds 51 are mounted together on the switching tray 54, which is mounted on the mounting bracket 52 and supported by the linear guide rail 57 that guides the movement of the switching tray. The switching tray is driven by the switching cylinder 55, so that the switching tray 54 drives the two support molds 51 to switch positions. The support mold 51 is in the form of a shaft. The support mold 51 includes a main body section 511 and a mold head 512 and a second ejector rod 513 respectively distributed at the upper and lower ends of the main body section. The mold head 512 is used to contact the support plate, and the mold head 512 can meet the processing needs of drilling and tapping while providing support. The second ejector rod 513 is embedded in an oil-free bushing 56, which is installed on a switching plate. The second ejector rod 513 is used to axially connect with the first ejector rod 531, so that the first ejector rod 531 lifts the second ejector rod 513 in the oil-free bushing 56, thereby raising the support plate of the support mold 51.

[0042] This utility model features a simple and practical structure, small size, and low investment cost. The mobile platform increases the load-bearing surface and enables moving material feeding, achieving automatic positioning and conveying of large sheet metal workpieces, reducing worker labor intensity. The linear tool magazine is effectively integrated into the mobile platform's motion system, adaptively providing various machining tools, enabling drilling, tapping, and countersinking of sheet metal on the same machine, improving work efficiency. The introduction of a floating support mechanism allows for matching support of sheet metal of different thicknesses, ensuring a stable distance between the sheet metal and the machining tools during processing, guaranteeing that the drilling, tapping, and countersinking depths match the set values. This completely solves the problems of sheet metal deformation and uncontrollable machining depth during drilling and tapping, especially in countersinking, where the countersinking depth can be precisely controlled, meeting the high-precision machining requirements of drilling and tapping machining centers. Multiple processing operations on a single machine improve processing efficiency and eliminate the problems of misalignment and missed holes during secondary processing of sheet metal parts.

[0043] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
