Description

Technical Field

[0001] This invention relates to the field of wood drilling technology, and more particularly to an adjustable drilling device for plywood and its usage method. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers (such as three-ply or five-ply), and the grain direction of adjacent veneers is glued perpendicular to each other to enhance structural stability. Through its cross-grain veneer structure, plywood effectively offsets the internal stress of the wood, reduces the risk of cracking, and has excellent tensile mechanical properties across the grain, making it suitable for load-bearing structures. After sanding, the surface of the board is smooth and can be directly used for veneering or painting. It can be used in furniture, packaging, building interiors, etc.

[0003] In the furniture manufacturing process, plywood is often used for the assembly and construction of furniture. During this process, the plywood needs to be processed to meet the usage requirements, such as cutting and drilling. Existing drilling equipment has certain defects in the process of processing plywood. For example, when drilling holes in plywood, drilling equipment will produce drilling debris (wood chips). After drilling is completed, workers need to clean the wood chips on the plywood, which is inconvenient. Summary of the Invention

[0010] As a further technical solution of the present invention, the elastic translation unit includes two side sliding grooves II opened on the side wall of the worktable, and a sliding block II is slidably arranged in each side sliding groove II. The sliding block II is fixedly connected to the side wall of the guide cover, and a spring is fixed between the sliding block II and the inner wall of the side sliding groove II.

[0011] As a further technical solution of the present invention, the clamping assembly includes two translation seats movably disposed on the upper surface of the worktable, and connecting seats are fixed on the opposite sides of the two translation seats. A lifting pressure plate is movably disposed directly below each connecting seat. A lifting drive mechanism is provided on each connecting seat to cooperate with the lifting pressure plate. Two translation drive mechanisms are provided on the worktable to cooperate with the corresponding translation seats.

[0012] As a further technical solution of the present invention, each of the lifting drive mechanisms includes a lifting cylinder fixedly disposed through the upper end face of the connecting seat. The end of the extension and retraction end of the lifting cylinder is fixedly connected to the upper end face of the lifting pressure plate. Two guide rods are symmetrically fixed to the upper end face of the lifting pressure plate, and each guide rod movably passes through the corresponding connecting seat.

[0013] As a further technical solution of the present invention, each of the translation drive mechanisms includes a sliding groove formed on the upper surface of the worktable. Two sliding guide rails are symmetrically fixed to the bottom of each sliding groove. The same sliding seat is slidably arranged on the two sliding guide rails. The translation seat is fixed to the upper surface of the corresponding sliding seat. A threaded rod is rotatably arranged in each sliding groove. The threaded rod passes through the sliding seat. A working motor is provided in the worktable to cooperate with the rotation of the corresponding threaded rod.

[0014] A method for using an adjustable drilling device for plywood, the specific steps of which are as follows: Step 1: Place the sheet material to be processed on the workbench, adjust and determine the position of the sheet material, and then clamp and fix the sheet material using the clamping components. Step two: The telescopic end of the electric actuator extends, driving the electric drill and drill bit to move downwards and closer to the board body. During the process of the drill bit processing the board body, the air blowing component works to generate airflow, which blows away the wood chips generated by the drilling on the upper surface of the board body. The wood chips fall into the guide hood, and then are finally guided into the collection bag by the guide hood and the discharge hood.

[0015] The beneficial effects of this invention are: 1. In the initial state of use, the telescopic end of the electric actuator is in a retracted state, thereby ensuring a large distance between the electric drill and the drill bit and the upper surface of the worktable, avoiding interference with the placement of the sheet material. The operator then places the sheet material to be processed on the worktable and adjusts the positions of the sheet material and the drill bit to determine the drilling location. The sheet material is then clamped and fixed by a clamping assembly to prevent displacement during drilling. Finally, the telescopic end of the electric actuator extends, causing the electric drill and drill bit to move downwards closer to the sheet material. During this process, the electric drill drives the drill bit to rotate, allowing it to create through holes in the board. As the drill bit processes the board, the air blowing component operates, generating airflow. This airflow diffuses across the upper surface of the board, carrying away the wood chips generated by the drilling (the airflow moves the wood chips towards the guide hood). Once the wood chips leave the upper surface of the board, they fall into the guide hood under gravity. Then, guided by the guide hood and the discharge hood, the wood chips finally fall into the collection bag, making it convenient to use.

[0016] 2. When the drill bit is working, the air pump also works, generating airflow. The airflow passes through the air hose and is finally discharged from the lower end of the air nozzle. The airflow first acts on the surface of the board body and then spreads on the surface of the board body. During the diffusion process, the airflow will carry away the wood chips generated by the drill bit while it is working, and at the same time, it will cool the drill bit.

[0017] 3. In the initial preparation stage, the two sealing plates are joined together to seal the inside of the discharge hood. Then, the worker places an empty collection bag on the outer surface of the discharge hood. The telescopic end of the dual-axis cylinder extends, pushing the two mounting plates away from each other. During this process, the sealing plates move with the corresponding abutment plates. The two sealing plates move away from each other, releasing the seal on the discharge hood. During this process, the abutment plates move with the mounting plates until the two abutment plates prop up the opening of the collection bag, preventing the opening of the collection bag from detaching from the discharge hood and affecting the collection of falling sawdust.

[0018] 4. During use, the working motor drives the rotating column to rotate, which in turn drives multiple actuating plates to rotate slowly counterclockwise. Through the cooperation of the rotating column and the actuating plates, some wood chips are prevented from passing directly over the top of the guide hood while moving with the airflow, thus preventing the wood chips from being collected. As the actuating plates rotate with the rotating column, they collide with and abut against the inner wall of the guide hood, causing the guide hood to move slightly. After a single actuating plate passes over the guide hood, the guide hood quickly returns to its original position under the action of the elastic translation unit. Then, the guide hood will collide with the inner wall of the notch, causing the guide hood to vibrate, which will cause the wood chips falling into the guide hood to slide down quickly.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Reference Figures 1-11 An adjustable drilling device for plywood includes a workbench 100. A notch 101 is formed on one side of the upper surface of the workbench 100. A guide cover 102 is provided on the inner wall of the notch 101. A discharge cover 103 is connected to the lower end of the guide cover 102. A collection bag 104 is fitted on the discharge cover 103. An electric push rod 105 is movably arranged on the workbench 100. An electric drill 106 is fixed at the lower end of the electric push rod 105. The electric drill 106 is prior art. A drill bit 107 is rotatably arranged at the working end of the electric drill 106. An air blowing component is provided on one side of the electric drill 106. A clamping component is provided on the workbench 100. A translation component used in conjunction with the electric push rod 105 is also provided on the workbench 100.

[0023] In use, the electric actuator 105 is initially retracted, ensuring a large distance between the drill 106 and drill bit 107 and the upper surface of the worktable 100. This avoids affecting the placement of the sheet metal 500. The operator then places the sheet metal 500 to be processed onto the worktable 100 and adjusts the positions of the sheet metal 500 and drill bit 107 to determine the drilling location. The sheet metal 500 is then clamped and fixed by a clamping assembly to prevent displacement during drilling. Finally, the electric actuator 105 extends, causing the drill 106 and drill bit 107 to move downwards closer to the sheet metal 500. During this process, the electric drill 106 drives the drill bit 107 to rotate, so that the drill bit 107 can process through holes in the board body 500. During the processing of the board body 500 by the drill bit 107, the air blowing component works to generate airflow. The airflow diffuses on the upper surface of the board body 500. In this process, the wood chips generated by the drilling on the upper surface of the board body 500 are carried away (the airflow drives the wood chips to move in a direction closer to the guide cover 102). After the wood chips leave the upper surface of the board body 500, the wood chips fall into the guide cover 102 under the action of gravity. Then, through the guidance of the guide cover 102 and the discharge cover 103, the wood chips finally fall into the collection bag 104, which is convenient to use.

[0024] The air blowing assembly includes an L-shaped connecting plate 108 fixed to one side of the electric push rod 105. An air blowing nozzle 109 is fixedly provided through the lower surface of the L-shaped connecting plate 108. An air blowing pump 110 is fixed to the upper end face of the electric push rod 105. An air blowing hose 111 is provided between the air blowing pump 110 and the air blowing nozzle 109.

[0025] When the drill bit 107 is working, the air pump 110 also works, generating airflow. The airflow is discharged from the lower end of the air nozzle 109 through the air hose 111. The airflow first acts on the surface of the board body 500, and then diffuses on the surface of the board body 500. During the diffusion process, the airflow will carry away the wood chips generated when the drill bit 107 is working, and at the same time, it will also cool the drill bit 107.

[0026] When the drill bit 107 finishes drilling and moves away from the board body 500, the air pump 110 also works for a period of time before stopping, to avoid leaving sawdust on the surface of the board body 500.

[0027] The air pump 110 and the drill bit 107 are spaced far apart in the horizontal direction to prevent the airflow generated by the air pump 110 from carrying the wood chips away from the guide cover 102.

[0028] The translation assembly includes two mounting brackets 112 fixed to the upper surface of the worktable 100. The upper surface of the two mounting brackets 112 is fixed with the same connecting bracket 113. A side slide groove 114 is provided on one side of the connecting bracket 113. A sliding block 115 is slidably arranged in the side slide groove 114. An electric push rod 105 is fixed to one side of the sliding block 115. A lead screw 116 is rotatably arranged in the side slide groove 114. The lead screw 116 is threaded through the sliding block 115. A working motor 117 that cooperates with the rotation of the lead screw 116 is fixed on one side of the connecting bracket 113.

[0029] If multiple through holes need to be opened on the upper surface of the board body 500, when the electric actuator 105 and the drill bit 107 finish drilling a through hole on the board body 500, the telescopic end of the electric actuator 105 retracts, driving the electric drill 106 and the drill bit 107 to move upward away from the board body 500. Then, the working motor 117 drives the lead screw 116 to rotate in the forward direction, thereby driving the sliding block 115 to move a certain distance, thereby moving the electric actuator 105, the electric drill 106 and the drill bit 107 to the next position where a hole needs to be opened. Then, the telescopic end of the electric actuator 105 extends, pushing the electric drill 106 and the drill bit 107 to move downward to perform drilling operations. According to the above working principle, multiple through holes are opened until they are completed.

[0030] Both sides of the discharge hood 103 are provided with sealing plates 200. A mounting plate 201 is fixed on the side of the sealing plate 200 away from the discharge hood 103. A contact plate 202 is fixed on one side of the mounting plate 201. Both sides of the discharge hood 103 are fixed with dual-axis cylinders 203. The end of the telescopic end of the dual-axis cylinder 203 is fixedly connected to the side wall of the corresponding mounting plate 201.

[0031] In the initial preparation stage, the two sealing plates 200 are brought together face to face to seal the inside of the discharge hood 103. Then, the worker places an empty collection bag 104 on the outer surface of the discharge hood 103. The telescopic end of the dual-axis cylinder 203 extends, pushing the two mounting plates 201 away from each other. During this process, the sealing plates 200 move with the corresponding abutment plates 202. The two sealing plates 200 move away from each other, releasing the seal on the discharge hood 103. During this process, the abutment plates 202 move together with the mounting plates 201 until the two abutment plates 202 prop up the opening of the collection bag 104, preventing the opening of the collection bag 104 from detaching from the discharge hood 103 and affecting the collection of the falling sawdust.

[0032] Two mounting blocks 300 are symmetrically fixed on the upper end face of the worktable 100. A rotating column 301 is rotatably arranged between the two mounting blocks 300. Multiple actuating plates 302 are fixed on the outer surface of the rotating column 301. A working motor 303 for use with the rotating column 301 is fixed on the side wall of one of the mounting blocks 300. An elastic translation unit for use with the guide cover 102 is provided on the worktable 100.

[0033] In use, the working motor 303 drives the rotating column 301 to rotate, and the rotating column 301 drives multiple actuating plates 302 to rotate slowly counterclockwise. Through the cooperation of the rotating column 301 and the actuating plates 302, some wood chips are prevented from passing directly over the guide cover 102 while moving with the airflow, thus preventing the wood chips from being collected. As the actuating plates 302 rotate with the rotating column 301, they collide with and abut against the inner wall of the guide cover 102, thereby causing the guide cover 102 to move slightly. When a single actuating plate 302 passes over the guide cover 102, the guide cover 102 quickly returns to its original position under the action of the elastic translation unit. Then, the guide cover 102 will collide with the inner wall of the notch 101, causing the guide cover 102 to vibrate, thereby causing the wood chips falling into the guide cover 102 to slide down quickly.

[0034] The elastic translation unit includes two side slide grooves 304 opened on the side wall of the worktable 100. Each side slide groove 304 is slidably provided with a sliding block 305. The sliding block 305 is fixedly connected to the side wall of the guide cover 102. A spring 306 is fixed between the sliding block 305 and the inner wall of the side slide groove 304.

[0035] When the actuating plate 302 moves against the guide cover 102, the guide cover 102 moves together with the sliding block 305. During the movement, the sliding block 305 stretches the spring 306. The spring 306 is stretched and deformed, storing elastic potential energy. When the actuating plate 302, which is against the inner wall of the guide cover 102, passes the guide cover 102, the guide cover 102 moves away from the rotating column 301 under the action of the spring 306. Then the guide cover 102 will collide with the inner wall of the notch 101.

[0036] The clamping assembly includes two translation seats 400 movably disposed on the upper surface of the worktable 100. Each of the two translation seats 400 has a connecting seat 401 fixed on its opposite side. A lifting pressure plate 402 is movably disposed directly below each connecting seat 401. Each connecting seat 401 is provided with a lifting drive mechanism that works in conjunction with the lifting pressure plate 402. The worktable 100 is provided with two translation drive mechanisms that work in conjunction with the corresponding translation seats 400.

[0037] After the sheet material 500 to be processed is placed on the upper surface of the workbench 100 and the drilling position is positioned with the drill bit 107, the translation drive mechanism drives the two translation seats 400 to move toward the sheet material 500 until the two translation seats 400 move the corresponding strokes until the sheet material 500 is clamped and fixed. Then the lifting drive mechanism drives the lifting pressure plate 402 to move down until the lifting pressure plate 402 abuts against the upper surface of the sheet material 500, further limiting and fixing the sheet material 500.

[0038] In use, one of the translation seats 400 can be kept stationary as a positioning reference line, allowing one side of the sheet body 500 to be processed to be attached to the inner wall of the stationary translation seat 400. Then, the drilling position is determined. Then, the other translation seat 400 is moved closer to the sheet body 500 to clamp and fix the sheet body 500. In short, determining the drilling position of the sheet body 500 is a conventional technical means in this field and belongs to the prior art, so it will not be described in detail here.

[0039] Each lifting drive mechanism includes a lifting cylinder 403 fixedly disposed on the upper end face of the connecting seat 401. The end of the extension end of the lifting cylinder 403 is fixedly connected to the upper end face of the lifting pressure plate 402. Two guide rods 404 are symmetrically fixed on the upper end face of the lifting pressure plate 402, and each guide rod 404 is movably disposed through the corresponding connecting seat 401.

[0040] In the initial state, the telescopic end of the lifting cylinder 403 is in a retracted state. When it is necessary to press and fix the plate body 500, the telescopic end of the lifting cylinder 403 extends, thereby pushing the lifting pressure plate 402 to move downward and press on the upper surface of the plate body 500.

[0041] Each translation drive mechanism includes a sliding groove 405 formed on the upper surface of the worktable 100. Two sliding guide rails 406 are symmetrically fixed to the bottom of each sliding groove 405. The same sliding seat 407 is slidably arranged on the two sliding guide rails 406. The translation seat 400 is fixed to the upper surface of the corresponding sliding seat 407. A threaded rod 408 is rotatably arranged in each sliding groove 405. The threaded rod 408 is threaded through the sliding seat 407. A working motor 3 is provided in the worktable 100 to cooperate with the rotation of the corresponding threaded rod 408.

[0042] During use, if the translation seat 400 needs to be moved, the working motor drives the threaded rod 408 to rotate, thereby driving the sliding seat 407 to move, which in turn drives the translation seat 400 to move.

[0043] A method for using an adjustable drilling device for plywood, the specific steps of which are as follows: Step 1: Place the sheet body 500 to be processed on the worktable 100, adjust and determine the position of the sheet body 500, and then clamp and fix the sheet body 500 using the clamping components. Step two: The telescopic end of the electric actuator 105 extends, driving the electric drill 106 and drill bit 107 to move downwards and approach the board body 500. During the processing of the board body 500 by the drill bit 107, the air blowing component works, generating airflow that blows away the wood chips generated by the drilling on the upper surface of the board body 500. The wood chips fall into the guide cover 102, and then, guided by the guide cover 102 and the discharge cover 103, finally fall into the collection bag 104.

[0044] In use, the electric actuator 105 is initially retracted, ensuring a large distance between the drill 106 and drill bit 107 and the upper surface of the worktable 100. This avoids affecting the placement of the sheet metal body 500. The operator then places the sheet metal body 500 to be processed onto the worktable 100 and adjusts the positions of the sheet metal body 500 and drill bit 107 to determine the drilling location. The sheet metal body 500 is then clamped and fixed using a clamping assembly to prevent displacement during drilling. Finally, the electric actuator 105 extends, causing the drill 106 and drill bit 107 to move downwards closer to the sheet metal body 500. During this process, the electric drill 106 drives the drill bit 107 to rotate, so that the drill bit 107 can process through holes in the board body 500. During the processing of the board body 500 by the drill bit 107, the air blowing component works to generate airflow. The airflow diffuses on the upper surface of the board body 500. During this process, the wood chips generated by the drilling on the upper surface of the board body 500 are carried away (the airflow drives the wood chips to move in a direction closer to the guide cover 102). After the wood chips leave the upper surface of the board body 500, the wood chips fall into the guide cover 102 under the action of gravity. Then, through the guidance of the guide cover 102 and the discharge cover 103, the wood chips finally fall into the collection bag 104, which is convenient to use. When the drill bit 107 is working, the air pump 110 also works, generating airflow. The airflow is discharged from the lower end of the air nozzle 109 through the air hose 111. The airflow first acts on the surface of the board body 500, and then spreads on the surface of the board body 500. During the diffusion process, the airflow will carry away the wood chips generated when the drill bit 107 is working, and at the same time, it will also cool the drill bit 107. In use, the working motor 303 drives the rotating column 301 to rotate, and the rotating column 301 drives multiple actuating plates 302 to rotate slowly counterclockwise. Through the cooperation of the rotating column 301 and the actuating plates 302, some wood chips are prevented from passing directly over the guide cover 102 while moving with the airflow, thus preventing the wood chips from being collected. As the actuating plates 302 rotate with the rotating column 301, they collide with and abut against the inner wall of the guide cover 102, thereby causing the guide cover 102 to move slightly. When a single actuating plate 302 passes over the guide cover 102, the guide cover 102 quickly returns to its original position under the action of the elastic translation unit. Then, the guide cover 102 will collide with the inner wall of the notch 101, causing the guide cover 102 to vibrate, thereby causing the wood chips falling into the guide cover 102 to slide down quickly.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
