Description

Technical Field

[0001] This invention relates to a sheet metal processing equipment, specifically a high-performance drilling and scribing integrated machine. Background Technology

[0002] The current board processing steps in the market are scribing, cutting, and drilling. Drilling equipment is CNC high-speed flat drill, and scribing equipment is large-format scribing machine. Due to the nature of the processing and actual working conditions, these are processed in two separate processes. CNC high-speed flat drill is mainly used for processing small boards, usually with a small processing area and high impact force. Because U-drills are contact-type processes, the table support strip will be damaged after a period of use, requiring frequent replacement. Scribing machines are usually used for processing large-size boards due to their high efficiency. However, the scribing machine's support table supports the entire board, and the board needs to be compacted during the scribing process to prevent air pockets. Therefore, the two types of equipment have different requirements for the worktable, making it difficult to integrate them. However, processing with these two types of equipment separately requires a large area, the intermediate transfer is cumbersome, and the processing efficiency is low. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a high-performance drilling and scribing integrated machine that combines drilling and scribing, thereby greatly reducing the floor space required and effectively improving processing efficiency.

[0004] To achieve the above objectives, this invention provides a high-performance drilling and scribing integrated machine. Multiple connected bed assemblies form a single-sided bed. A fixed beam drilling assembly mounting seat is fixedly installed on the upper surface of the single-sided bed near its end. Two single-sided beds are connected by a bed connecting frame and bed connectors to form a main bed. The fixed beam drilling assembly spans the main bed and is fixed to the fixed beam drilling assembly mounting seat. The moving beam scribing assembly moves back and forth on the main bed.

[0013] The following description, in conjunction with the accompanying drawings, describes a high-performance drilling and scribing machine of the present invention.

[0014] In Embodiment 1 of this application, as Figures 1 to 8As shown, this high-performance drilling and scribing integrated machine (hereinafter referred to as "the present invention") comprises multiple bed components 11 connected in series to form a single-sided bed. A fixed beam drilling component mounting seat 14 is fixedly installed on the upper surface of the single-sided bed near its end. Two single-sided beds are connected by a bed connecting frame 12 and a bed connecting piece 13 to form a main bed 1. A fixed beam drilling component 4 spans the main bed 1 and is fixed on the fixed beam drilling component mounting seat 14. A movable beam scribing component 3 moves back and forth on the main bed 1. The inner side of the main bed 1... The support workbench 2 is formed by two rows of support roller assemblies 21, and a feeding clamp 5 is set between the two rows of support roller assemblies 2. The support workbench 21 is divided into a five-roller frame 212 and a two-roller frame 211. The five-roller frame 212 and the two-roller frame 211 are arranged in groups. The five-roller frame 212 is equipped with a limiting roller 23, which is controlled by a limiting roller control cylinder 231. A positioning roller 22 is set on the outside of the support workbench 21. The drilling area 24 is set between the two roller frames 211. The bed assembly 11 includes a toothed belt slide rail mounting position 111 and mounting positioning holes 115. The toothed belt slide rail mounting position 111 is located on the upper part of the bed assembly 11. Multiple side stiffening plates 112 and lifting process round holes 113 are alternately arranged on both sides of the bed assembly 11. A central stiffening plate 114 is provided on the inner side of the bed assembly 11. Mounting positioning holes 115 are opened at both ends of the bed assembly 11. The main bed 1 part is made of cast bed assembly 11, with a central stiffening plate 114 designed in the middle for support. Side stiffening plates 112 are added to the sides. The lifting process round holes 113 are used for lifting the bed. The overall bed has good load-bearing rigidity and minimal deformation. The main bed 1 is spliced ​​from multiple bed assemblies 11. Mounting positioning holes 115 are machined on the top and sides of the bed assembly 11 for easy positioning and clamping. The support roller assembly 2 consists of multiple sets of five-roller frames 212 and two-roller frames 211, used for supporting and conveying the sheet metal. A drilling area 24 is located between the two-roller frames 211 for drilling in a fixed area to prevent damage to the worktable. The worktable is equipped with positioning rollers 22, limiting rollers 23, and limiting roller control cylinders 231. The positioning rollers 22 are mainly used for reference positioning of the sheet metal. The limiting rollers 23, driven by the limiting roller control cylinders 231, position and lock the sheet metal on the other side, preventing movement or translational displacement during the scratching process and ensuring processing accuracy. Some of the five-roller frames 212 and two-roller frames 211 are located outside the main bed 1, forming the discharge area, while some of the five-roller frames 212 and two-roller frames 211 inside the main bed 1 form the loading area.

[0015] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 9 and Figure 10As shown, the feeding clamp 5 includes a clamp body 51 and a clamp slide rail 52. The clamp slide rail 52 of the feeding clamp 5 is arranged between the two rows of support roller assemblies 2. The clamp base 511 of the clamp body 51 moves back and forth on the clamp slide rail 52. The clamp lifting seat 513 slides up and down along the clamp lifting guide rail 512 of the clamp base 511. An extension sleeve 517 is fixedly installed on the surface of the clamp lifting seat 513. A chuck 518 is fixedly installed at the end of the extension sleeve 517. An extension rod 516 is movably installed inside the extension sleeve 517. A sliding guide sleeve 519 inside the chuck 518 restricts the extension. The direction of movement of lever 516 is such that one end of clamp control cylinder 514 is hinged to the upper part of clamp lifting seat 513, and the other end controls the extension lever 516 to slide back and forth inside the chuck 518 via control link 515. The middle part of control link 515 is movably mounted on the bracket of extension sleeve 517 via a rotating shaft. A sliding pressure plate 5110 is provided at the end of extension lever 516. The front end of sliding pressure plate 5110 has a slanted triangular structure. The slanted triangular structure of sliding pressure plate 5110 controls the upper pressure plate 5112 and lower pressure plate 5111 to clamp. A retraction spring is provided at the rear of upper pressure plate 5112 and lower pressure plate 5111. During processing, the clamp control cylinder 514 retracts, causing the control linkage 515 to drive the extension rod 516 to extend forward. The sliding pressure plate 5110 at the end of the extension rod 516 is inserted between the upper pressure plate 5112 and the lower pressure plate 5111, causing the upper pressure plate 5112 to press down. This allows the upper pressure plate 5112 and the lower pressure plate 5111 to clamp the workpiece. The drive motor on the clamp base 511 moves back and forth on the clamp slide rail 52 via a toothed belt and gears, thereby controlling the position of the workpiece on the support roller assembly 2.

[0016] To further optimize the efficiency of this application, such as Figures 11 to 14As shown, the moving beam scribing assembly 3 includes a moving base 31, a scribing head translation seat 33, and a scribing head 34. The moving base 31 is fixedly installed at the lower part of both ends of the moving beam 32. The moving base 31 moves back and forth on the main bed 1. The scribing head translation seat 33 is movably installed on the moving beam 32. The scribing head 34 is provided at the lower part of the scribing head translation seat 33. The fixed beam drilling assembly 4 includes a fixed beam body 41, an automatic tool changer 42, a pressure plate 48, and a drilling translation seat 49. The fixed beam body 41 has its own fixed beam drilling assembly mounting base 14 fixedly connected to both ends. An automatic tool changer 42 is located near the lower end of the fixed beam body 41. The drilling translation seat 49 is movably mounted on the fixed beam body 41. A clamping cylinder 45 is fixedly mounted on both sides of the drilling translation seat 49. The lower end of the clamping cylinder 45 is connected to the pressure plate 48, which is used to lock the plate material for drilling. Guide sleeves are provided on both sides of the drilling translation seat 49. Guide posts on both sides of the pressure plate 48 are inserted into the guide sleeves. A slide 46 is movably mounted on the surface of the drilling translation seat 49 via a slide rail. A motor on the drilling translation seat 49 drives a lead screw and a slider to control the lifting and lowering of the slide 46. A U-drill 47 is mounted on the slide 46. A tool-changing cylinder 43 drives the U-drill 47 to change tools. A drive motor 44 is connected to a synchronous pulley, which uses a synchronous belt to drive the spindle of the U-drill 47 to rotate. The base of the automatic tool changer module 42 is fixedly installed under the fixed beam body 41. A tool holder is mounted inside the base via a slide rail. A protective plate 421 is mounted on the upper part of the base via a hinge. The tool holder extends and retracts within the base under cylinder control. When the tool holder retracts, the protective plate 421 falls down to prevent dust and also to prevent chips from flying and scratching the tool. The automatic tool changer module 42 is mainly used for automatic tool changing during machining, replacing U-drills 47 with those of different hole diameters, improving tool changing efficiency and reducing manual intervention. The U-drill 47 and the automatic tool changer module 42 are mainly used for actual drilling. The U-drill 47 and the automatic tool changer module 42 are respectively mounted on the fixed beam body 41 to jointly complete the drilling process. The bases of the five-roller frame 212 and the two-roller frame 211 are both equipped with rollers via bearings.

[0017] When in use, this invention works as follows: The sheet material is transported to the loading side by a crane. After the entire sheet is placed, the limit roller control cylinder 231 extends and uses the limit roller 23 to press the sheet material. One side of the sheet material is pressed against the positioning roller 22 for precise positioning. The feeding clamp 5 moves to the tail of the sheet material. The clamp control cylinder 514 of the feeding clamp 5 extends the control linkage 515 and the extension rod 516 to drive the sliding pressure plate 5110 to insert between the lower pressure plate 5111 and the upper pressure plate 5112, so that the lower pressure plate 5111 and the upper pressure plate 5112 clamp the sheet material, thus completing the sheet material positioning. The processing program is imported into the host computer through nesting software. The operator sets the layer process and then starts executing the program. The moving beam scribing component 3 moves to the vicinity of the sheet material. Three-point positioning and edge inspection are performed. After the edge inspection is completed, the program processing begins. During the scribing process, the board is fixed and the moving beam scribing component 3 performs dynamic scribing processing along the main bed 1. After processing is completed, the moving beam scribing component 3 moves to the zero point position and begins the next drilling process. During drilling, the feeding clamp 5 conveys the board forward to participate in the interpolation movement, and the fixed beam drilling component 4 processes in a fixed position. Since the lower end of the U-drill 47 has a hollow structure, damage to the U-drill 47 can be effectively avoided. As the board is continuously conveyed forward for processing, the drilling process is completed. After processing is completed, the whole board is moved to the discharge side, and the crane transports it to the next cutting process for cutting processing, thus continuously cycling the processing.

[0018] In summary, the high-performance drilling and scribing integrated machine of this invention, through the design of a brand-new support roller assembly 2, combined with the optimized main bed 1 and feeding clamp 5, can combine drilling and scribing, thereby greatly reducing the floor space and effectively improving processing efficiency.
