Description

Technical Field

[0001] This utility model relates to the field of hole processing technology, specifically to a sheet drilling machine with multi-axis linkage positioning. Background Technology

[0002] Sheet drilling is a process that uses specialized equipment to create holes of specific sizes and shapes on various sheet materials. In fields such as electronics, aerospace, and furniture manufacturing, sheet drilling is widely used in circuit board fabrication and structural component assembly, laying the foundation for subsequent assembly and functional realization.

[0003] Utility model patent CN215392596U discloses a fully automatic dual-station sheet drilling equipment. This equipment includes a main body, a drive mechanism, a support column, a lifting mechanism, a support rod, a drilling machine, a drill bit, a worktable, and a detection mechanism. The drive mechanism is located on one side of the main body, and the support column and worktable are located on the upper outer surface of the main body. The support column is located on one side of the worktable, and the lifting mechanism is located on the upper outer surface of the support column. A support rod is located on one side of the lifting mechanism. The worktable, after installation, allows the sheet material to be blocked by the baffle plate at the top of the pad. The limiting block at the top of the chute can move and adjust along the chute, thereby clamping and limiting the sheet material, preventing it from shifting due to the force of the drill bit during processing.

[0004] This fully automatic dual-station sheet drilling machine clamps and limits the sheet material using a baffle plate on the worktable pad and a movable limiting block in the chute. When processing sheets in batches, the operator needs to adjust and fix the position of each sheet on the pad one by one before drilling. This positioning step needs to be repeated before each drilling operation, which makes the processing process cumbersome, consumes a lot of time, and reduces the overall processing efficiency of the sheet material. In view of this, we propose a multi-axis linkage positioning sheet drilling machine. Utility Model Content

[0005] The purpose of this invention is to provide a multi-axis linkage positioning sheet drilling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-axis linkage positioning sheet drilling machine includes a drilling machine body, on which a drilling platform for placing sheet material is provided. Planar positioning components are provided around the drilling platform to position the sheet material on the drilling platform. The drilling machine body is also provided with a vertical positioning mechanism to apply longitudinal pressure to the positioned sheet material. Guide grooves are provided on all four sides of the drilling platform; The planar positioning assembly includes a clamping seat that moves along the guide groove and an adjusting screw that extends into the guide groove and is threadedly connected to the clamping seat. The circumferential rotation of the adjusting screw is converted into linear movement of the clamping seat along the axis of the guide groove by the screw thread, and the clamping seat abuts against the edge of the sheet. The vertical positioning mechanism includes two pressing components symmetrically installed on the main body of the drilling machine and a pressing block overlapping between the two pressing components. The pressing component includes a guide post longitudinally installed on the main body of the drilling machine and a pressing foot that moves along the guide post. The end of the pressing foot is pressed against the top of the sheet under the gravity of the pressing block.

[0007] Preferably, a central hole is provided at the middle position of the drilling platform, and the position of the central hole corresponds to the position of the drill bit of the drilling machine body.

[0008] In this setup, the center hole corresponds to the drill bit position, which facilitates the falling of debris during drilling, reduces the accumulation of debris on the platform surface, keeps the operating area clean, and allows the drill bit to pass smoothly through the platform to process the sheet material.

[0009] Preferably, the clamping seat is attached to the top surface of the drilling platform, and a movable seat is provided below the clamping seat. The movable seat is sleeved in the guide groove, and a connecting block is connected between the clamping seat and the movable seat. The width of the connecting block is smaller than the width of the movable seat. A through groove is formed between the guide groove and the surface of the drilling platform for the connecting block to pass through. When the movable seat moves along the guide groove, the connecting block moves along the through groove.

[0010] In this setup, the cooperation between the movable seat, connecting block, and through groove ensures smooth movement of the clamping seat, prevents it from dislodging from the guide groove, and ensures sheet positioning.

[0011] Preferably, the adjusting screw passes through the movable seat and is threadedly connected to the movable seat. The first and last ends of the adjusting screw are respectively rotatably connected to a head end block and a tail end block, and the head end block and the tail end block are respectively fixed to the first and last ends of the guide groove.

[0012] In this configuration, the head end block and tail end block fix the adjusting screw, providing stable support for its rotation and ensuring stability when the adjusting screw drives the movable seat to move.

[0013] Preferably, the first end of the adjusting screw is provided with a convex shaft, the convex shaft passes through the first end block and is rotatably connected to the first end block, the tail end of the convex shaft is provided with a stop block, and the end of the adjusting screw passes through the tail end block and is equipped with a handle.

[0014] In this configuration, the convex shaft, stop, and handle facilitate the operator's rotation of the adjusting screw to achieve precise adjustment of the clamping seat position.

[0015] Preferably, a fixing seat is installed at both the top and bottom ends of the guide column, and the end of the fixing seat is fixedly connected to the main body of the drilling machine.

[0016] In this setup, the mounting base securely installs the guide post onto the main body of the drilling machine, providing a stable guiding foundation for the movement of the pressure foot.

[0017] Preferably, the first end of the presser foot is provided with a movable sleeve, which is sleeved on the outside of the guide post and slidably connected to the guide post, and a lever is provided on the outside of the movable sleeve.

[0018] In this setup, the movable sleeve and lever allow operators to easily adjust the height of the presser foot to accommodate sheets of different thicknesses, thus enhancing the equipment's applicability.

[0019] Preferably, the bottom end of the pressure block is provided with a pair of slots, and when the pressure block is placed between the two pressing components, the top end of the pressure foot extends into the slot.

[0020] In this configuration, the slot engages with the presser foot to ensure that the weight of the press block is evenly transferred to the presser foot, thereby ensuring that a stable longitudinal pressure is applied to the sheet.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. This multi-axis linkage positioning sheet drilling machine, by setting up planar positioning components around the drilling platform, uses adjusting screws to drive the clamping seat to move linearly along the guide groove. The position of the clamping seat can be pre-adjusted so that the planar positioning components form a fixed space that is suitable for sheets of the same size. When processing sheets in batches, sheets of the same size can be quickly placed in this space without the need for tedious position fine-tuning. 2. This multi-axis linkage positioning sheet drilling machine, through the cooperation of the pressure block and pressure foot set on the vertical positioning mechanism, can quickly apply longitudinal pressure to fix the sheet after it is placed, reducing the operation steps of the sheet positioning process, and can realize simultaneous and rapid positioning of multiple sheets after stacking, saving positioning time and thus improving the efficiency of batch processing of sheets.

[0023] Dongguan Liqi Industrial Co., Ltd. will now provide a clear and complete description of the technical solutions in the embodiments of this utility model with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1 Please see Figures 1-5 A multi-axis linkage positioning sheet drilling machine includes a drilling machine body 100, on which a drilling platform 110 for placing sheet metal is provided. Guide grooves 130 are formed on all four sides of the drilling platform 110, and planar positioning components 200 are provided around the drilling platform 110. The planar positioning components 200 are used to position the sheet metal on the drilling platform 110. By providing guide grooves 130 and planar positioning components 200 around the drilling platform 110, a structural basis is provided for the positioning of the sheet metal, allowing the position of the sheet metal on the drilling platform 110 to be accurately adjusted and fixed.

[0025] like Figure 2As shown, in this utility model, a central hole 120 is provided at the middle position of the drilling platform 110, and the position of the central hole 120 corresponds to the position of the drill bit on the main body 100 of the drilling machine. With the central hole 120 corresponding to the drill bit position, during drilling, debris generated during drilling can fall through the central hole 120, preventing debris from accumulating on the drilling platform 110 and affecting sheet positioning and drilling operations, while also facilitating subsequent cleaning.

[0026] like Figure 1 and Figure 3 As shown, specifically, the planar positioning assembly 200 includes a clamping seat 210 that moves along the guide groove 130 and an adjusting screw 220 that extends into the guide groove 130 and is threadedly connected to the clamping seat 210. The circumferential rotation of the adjusting screw 220 is converted into linear movement of the clamping seat 210 along the axis of the guide groove 130 by the action of the thread, with the clamping seat 210 abutting against the edge of the sheet. The threaded connection design between the adjusting screw 220 and the clamping seat 210 allows for precise control of the movement of the clamping seat 210 along the guide groove 130 by rotating the adjusting screw 220, thereby pressing and positioning the edges of sheets of different sizes, keeping the sheet fixed in the horizontal direction, and preventing displacement during drilling.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping seat 210 is further fitted onto the top surface of the drilling platform 110. A movable seat 211 is located below the clamping seat 210 and is fitted within the guide groove 130. A connecting block 212 connects the clamping seat 210 and the movable seat 211. The width of the connecting block 212 is smaller than the width of the movable seat 211. A through groove is formed between the guide groove 130 and the surface of the drilling platform 110 for the connecting block 212 to pass through. When the movable seat 211 moves along the guide groove 130, the connecting block 212 moves along the through groove. The mating structure of the movable seat 211, the connecting block 212, and the through groove ensures the stability and guidance of the clamping seat 210 during movement, allowing it to move smoothly along the guide groove 130. Simultaneously, the width design of the connecting block 212 prevents the movable seat 211 from dislodging from the guide groove 130, ensuring the normal operation of the positioning assembly.

[0028] like Figure 3 and Figure 5As shown, the adjusting screw 220 passes through the movable seat 211 and is threadedly connected to the movable seat 211. The adjusting screw 220 has a head end block 230 and a tail end block 240 at its head and tail ends, respectively. The head end block 230 and the tail end block 240 are fixed at the head and tail ends of the guide groove 130, respectively. The head end block 230 and the tail end block 240 play a role in fixing and supporting the adjusting screw 220, ensuring that the adjusting screw 220 remains stable during rotation. The adjusting screw 220 has a convex shaft 221 at its head end, which passes through the head end block 230 and is rotatably connected to the head end block 230. The tail end of the convex shaft 221 has a stop block 222. The end of the adjusting screw 220 passes through the tail end block 240 and is equipped with a handle 223. The convex shaft 221, the stop block 222 and the handle 223 make it convenient for the operator to rotate the adjusting screw 220 to achieve convenient adjustment of the position of the clamping seat 210.

[0029] In this embodiment, the multi-axis linkage positioning sheet drilling machine is used as follows: First, the sheet is placed on the drilling platform 110. According to the size of the sheet to be processed, the handle 223 of the adjusting screw 220 is rotated to make the handle 223 drive the adjusting screw 220 to rotate. Through the threaded transmission, the movable seat 211 drives the clamping seat 210 to move along the guide groove 130. Then, the positions of the clamping seats 210 in the four directions are adjusted so that the edge of the sheet abuts against the four clamping seats 210. At this time, the sheet is positioned by the surrounding planar positioning components 200. Finally, the drilling machine body 100 is started, and the drill bit drills the sheet through the central hole 120. Since the planar positioning components form a fixed space that adapts to sheets of the same size, when processing sheets in batches, sheets of the same size can be quickly placed in this space without the need for tedious position fine-tuning.

[0030] Example 2 like Figure 1 , Figure 6 and Figure 7 As shown, the drilling machine body 100 is also equipped with a vertical positioning mechanism 300. The vertical positioning mechanism 300 is used to apply longitudinal pressure to the positioned sheet. The vertical positioning mechanism 300 includes two pressing components 310 symmetrically installed on the drilling machine body 100 and a pressure block 320 overlapping between the two pressing components 310. The vertical positioning mechanism 300 can apply longitudinal pressure to the sheet after the sheet has been horizontally positioned, further fixing the sheet and preventing the sheet from tilting or shaking due to the drill bit pressure during drilling, thereby improving drilling accuracy.

[0031] like Figure 6As shown, in this embodiment, the pressing assembly 310 includes a guide post 311 longitudinally mounted on the drilling machine body 100 and a pressing foot 312 movable along the guide post 311. The end of the pressing foot 312 is pressed against the top of the sheet under the gravity of the pressing block 320. The guide post 311 provides guidance for the movement of the pressing foot 312, ensuring that the pressing foot 312 can move vertically downward; the gravity of the pressing block 320 causes the pressing foot 312 to apply stable pressure to the top of the sheet, firmly fixing the sheet to the drilling platform 110.

[0032] like Figure 6 As shown, specifically, both the top and bottom ends of the guide post 311 are equipped with fixed seats 3111. The ends of the fixed seats 3111 are fixedly connected to the main body 100 of the drilling machine, ensuring that the guide post 311 is stably installed on the main body 100 of the drilling machine. The first end of the pressure foot 312 is provided with a movable sleeve 3121. The movable sleeve 3121 is fitted on the outside of the guide post 311 and slidably connected to the guide post 311. The outside of the movable sleeve 3121 is provided with a lever 3122. The design of the movable sleeve 3121 and the lever 3122 makes it easy for the operator to move the movable sleeve 3121 up and down along the guide post 311 by moving the lever 3122, thereby adjusting the height of the pressure foot 312 to accommodate sheets of different thicknesses. It can also be used to press down multiple stacked sheets.

[0033] like Figure 6 and Figure 7 As shown, the bottom end of the pressure block 320 is provided with a pair of slots 321. When the pressure block 320 is placed between the two pressing components 310, the top end of the pressure foot 312 extends into the slots 321. The engagement between the slots 321 and the top end of the pressure foot 312 ensures that the weight of the pressure block 320 is accurately transferred to the pressure foot 312, guaranteeing that the pressure foot 312 applies stable and uniform pressure to the sheet, thereby enhancing the fixing effect on the sheet.

[0034] In this embodiment of the multi-axis linkage positioning sheet drilling machine, firstly, after the sheet is horizontally positioned by the planar positioning component 200, the height of the pressure foot 312 is adjusted by the lever 3122 to maintain a suitable distance from the top of the sheet; then, the pressure block 320 is placed between the two pressing components 310, so that the top of the pressure foot 312 extends into the slot 321; next, the weight of the pressure block 320 is transmitted to the pressure foot 312 through the slot 321, so that the pressure foot 312 applies longitudinal pressure to the top of the sheet to fix the sheet; finally, the drilling machine body 100 is started to perform drilling operations.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
