Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically a drilling equipment for sheet metal with adjustable spacing. Background Technology

[0002] Furniture is an essential tool for production and social activities, and an indispensable part of family life. Furniture is made of various boards, and these boards need to be drilled during processing to facilitate later assembly and use. Usually, drilling equipment is used to drill holes in furniture boards. Traditionally, when drilling holes in boards, a locator is often used to fix the board in place. The drill bit is inserted into the hole of the locator to make the hole. This means that different locators need to be replaced when drilling holes of different diameters, which makes the replacement time longer. At the same time, the spacing between holes also needs to be adjusted manually, which affects the drilling efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a drilling device for sheet metal with adjustable spacing to solve the problems mentioned in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A plate drilling device with adjustable spacing includes a machine body, a fixed platform at the bottom of the machine body, a fixing component on the side of the machine body near the fixed platform, a hydraulic cylinder on the machine body, a rotating shaft on the push rod of the hydraulic cylinder, the rotating shaft being rotatably connected to the push rod of the hydraulic cylinder, the rotating shaft being connected to the fixing component, and a drilling component being disposed inside the fixing component. The worker places the board on the fixed platform, and then the controller activates the hydraulic cylinder. The push rod of the hydraulic cylinder then pushes the rotating shaft to move, causing the rotating shaft to move the fixed component, which presses the fixed component against the surface of the board, thus pressing and fixing the board to prevent displacement during drilling and resulting in poor drilling quality. After the fixed component is pressed and fixed, the controller controls the drilling component to move closer to the board, allowing the drilling component to complete the drilling process. After drilling one hole, the controller controls the fixed component and the drilling component to reset, and then uses the rotating shaft to rotate the drilling component to the top of the next hole, and then drills the next hole.

[0005] Preferably, the fixing component includes a support plate and a rotating ring. The support plate is connected to the rotating shaft, and the support plate and the rotating ring are directly connected through a bracket. A fixing ring is provided on the side of the rotating ring away from the support plate.

[0006] Preferably, a toothed ring is provided on the outer wall of the rotating ring, and a drive motor is provided on the side of the machine body near the rotating ring. A main gear is provided on the drive shaft of the drive motor, and the main gear meshes with the toothed ring. When drilling is completed in one hole and the drill bit needs to be moved to the next hole, the controller starts the drive motor. The drive shaft of the drive motor drives the main gear to rotate, which meshes with the gear ring. The gear ring then drives the rotating ring to rotate, which in turn drives the moving frame to rotate. This causes the moving frame to rotate the drill bit, moving it above the next hole to be drilled. The drive motor then drives the gear ring to rotate, matching the rotation angle of the gear ring with that of the drill bit. This changes the rotation angle between holes and adjusts the gap between them.

[0007] Preferably, an electric cylinder is provided on the side of the support plate near the rotating ring, a movable frame is provided on the push rod of the electric cylinder, and a support rod is also provided on the side of the support plate near the rotating ring. The support rod passes through the movable frame, and the movable frame is slidably connected to the support rod. After the fixing ring presses and fixes the plate, the controller controls the electric cylinder to move. The push rod of the electric cylinder then pushes the moving frame to move, so that the moving frame drives the first chuck and the second chuck to move closer to the plate. The moving frame moves along the axis of the support rod.

[0008] Preferably, two transformation bodies are provided on the side of the movable frame away from the support plate, and the two transformation bodies form a scissor structure, with the axis of the support rod as the rotation center axis of the two transformation bodies.

[0009] Preferably, the transforming body is composed of a long rod and a short rod. The bottom of the long rod is provided with an arc-shaped plate, and the two ends of the long rod are respectively provided with extension strips. The size of the extension strip on the side closer to the short rod is smaller than that on the side closer to the fixing ring. The space enclosed by the two long rods and the arc-shaped plate is a drilling space. The two short rods are provided with tapered grooves on the side closer to the moving frame. Because the two transforming bodies combine to form a scissor structure, the positioning post pushes the two short rods apart, making the angle formed by the two short rods the same as the angle formed by the two long rods. By changing the diameter of the positioning post, the rotation angle of the transforming bodies can be changed, thereby changing the drilling space enclosed by the long rods. The axis of the drill bit coincides with the perpendicular line of the midpoint of the two long rods when they are in contact with each other. Thus, the size of the drilling space matches the size of the drill bit, avoiding the need to replace the positioning device at the same time when changing the drill bit, thereby improving the efficiency of drilling plates.

[0010] Preferably, a sliding groove is provided on the side wall of the fixing ring, two sliding strips are symmetrically arranged in the sliding groove, a spring is provided between the sliding strip and the side wall of the sliding groove, the sliding strip is slidably connected to the sliding groove, and a push plate is provided on the side of the long rod near the sliding groove, the push plate extends into the sliding groove, and the push plate contacts the sliding strip.

[0011] Preferably, the drilling assembly consists of a first chuck and a second chuck, which are located at the two ends of the movable frame, respectively. The first chuck is located above the long rod, and the second chuck is located above the short rod. A drill bit is placed on the first chuck, and a positioning post is placed on the second chuck. The positioning post is a telescopic post, and the axis of the second chuck coincides with the axis of the tapered groove. By replacing the positioning pins with different diameters, the diameter of the positioning pins is matched with the diameter of the drill bit. Since the axis of the second chuck coincides with the axis of the tapered groove, the axis of the positioning pins also coincides with the axis of the tapered groove. The second chuck, influenced by the moving frame, causes the positioning pin to move closer to the conical groove. During this movement, the positioning pin contacts the conical groove, which then pushes the groove apart. This causes the two short rods to separate. As the short rods rotate, they drive the long rod to rotate. This rotation causes the arc plate and push plate to rotate, moving them to opposite sides. As the push plate moves, it drives the sliding strips to move. The two sliding strips then move along the sliding groove to opposite sides, allowing the drilling space enclosed by the two long rods to connect with the outside world through the sliding groove.

[0012] Preferably, a water supply pipe is provided inside the support rod, a liquid storage chamber is provided inside the machine body, a water pump is provided inside the liquid storage chamber, the water pump is connected to the water supply pipe through a pipe, a water outlet is provided on the bottom of the water supply pipe near the long rod, a collection trough is provided on the side of the fixed platform near the fixed ring, the collection trough is connected to the liquid storage chamber through a pipe, and a flow channel is provided on the edge of the fixed platform, the flow channel is connected to the collection trough; When the long rod deflects due to the rotation of the short rod, it drives the extension bars at both ends to rotate, thus connecting the outlet to the drilling space. Simultaneously, the drilling space connects to the outside via a sliding groove. At this point, the controller starts the water pump, which draws coolant from the storage chamber and transports it through a pipeline to the water supply pipe, then to the outlet, and finally outputs it into the drilling space. During coolant transport, the coolant flows from the intersection of the two long rods towards the side closer to the sliding groove, gradually increasing the cross-section of the flow channel and extending the coolant's flow time within the drilling space. This not only cools the drill bit but also washes away drilling debris. Some coolant flows through the sliding groove to the flow channel at the edge of the fixed platform. After the drill bit completes the hole, some coolant flows through the hole into the collection tank. The generated debris is filtered in the flow channel and collection tank, while the coolant flows back into the storage chamber through the pipeline.

[0013] As the positioning column descends, it opens the conical groove, causing the long rod to rotate under the action of the short rod. This opens up the drilling space, allowing the drill bit to enter without obstruction. Subsequently, the controller starts the drilling motor connected to the first chuck. The drive shaft of the drilling motor drives the first chuck to rotate, which in turn drives the drill bit to rotate. As the drill bit rotates, the push rod of the electric cylinder pushes the moving frame to move, causing the moving frame to push the first chuck to one side of the drill bit, allowing the drill bit to punch and drill into the plate, thus achieving the drilling process.

[0014] Preferably, the curvature of the extension strip near the outlet is greater than the curvature of the outlet, and the curvature of the extension strip near the sliding groove is greater than the curvature of the sliding groove. By making the curvature of the extension bar greater than that of the outlet and the sliding groove, the extension bar can always limit the opening range of the outlet and the sliding groove when the long rod deflects at different angles. This ensures that the drilling space is always isolated from other areas within the fixed ring, thereby limiting the flow area of ​​the coolant. Furthermore, the long rod and the arc plate can block the debris generated during drilling, preventing debris from splashing everywhere.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Because the two transforming bodies combine to form a scissor structure, the positioning post pushes the two short rods apart, making the angle formed by the two short rods the same as the angle formed by the two long rods. By changing the diameter of the positioning post, the rotation angle of the transforming bodies can be changed, thereby changing the drilling space enclosed by the long rods. The axis of the drill bit coincides with the perpendicular line of the midpoint of the two long rods when they are in contact with each other. Thus, the size of the drilling space matches the size of the drill bit, avoiding the need to replace the positioning device at the same time when changing the drill bit, thereby improving the efficiency of drilling plates.

[0016] 2. The coolant is output to the drilling space through the outlet. During the coolant delivery process, the coolant is output from the intersection of the two long rods and flows towards the side closer to the sliding groove. This causes the cross-section of the coolant flow channel to gradually increase, which increases the time that the coolant flows in the drilling space. As a result, the coolant can not only cool down the drill bit, but also wash away the debris generated by the drill bit during drilling.

[0017] 3. By making the curvature of the extension bar greater than that of the outlet and the sliding groove, the extension bar can always limit the opening range of the outlet and the sliding groove when the long rod deflects at different angles. This ensures that the drilling space is always isolated from other areas within the fixed ring, thereby limiting the flow area of ​​the coolant. Furthermore, the long rod and the arc plate can block the debris generated during drilling, preventing debris from splashing everywhere. Attached Figure Description

The size of the extension strip 274 near the short rod 272 is smaller than that of the extension strip 274 near the fixing ring 23. The space enclosed by the two long rods 271 and the arc-shaped plate 273 is a drilling space. A tapered groove 275 is provided on the side of the two short rods 272 near the moving frame 25.

[0026] In one specific embodiment of the present invention, a sliding groove 28 is provided on the side wall of the fixing ring 23, and two sliding strips 281 are symmetrically arranged in the sliding groove 28. A spring is provided between the sliding strips 281 and the side wall of the sliding groove 28. The sliding strips 281 are slidably connected to the sliding groove 28. A push plate 276 is provided on the side of the long rod 271 near the sliding groove 28. The push plate 276 extends into the sliding groove 28 and contacts the sliding strips 281.

[0027] In one specific embodiment of the present invention, the drilling assembly 3 consists of a first chuck 31 and a second chuck 32. The first chuck 31 and the second chuck 32 are respectively located at both ends of the movable frame 25. The first chuck 31 is located above the long rod 271, and the second chuck 32 is located above the short rod 272. A drill bit 33 is placed on the first chuck 31, and a positioning post 34 is placed on the second chuck 32. The positioning post 34 is a telescopic post, and the axis of the second chuck 32 coincides with the axis of the tapered groove 275.

[0028] In one specific embodiment of the present invention, a water supply pipe 261 is provided inside the support rod 26, a liquid storage chamber is provided inside the body 1, a water pump is provided inside the liquid storage chamber, the water pump is connected to the water supply pipe 261 through a pipe, an outlet 262 is provided at the bottom of the water supply pipe 261 near the long rod 271, a collection trough 14 is provided on the side of the fixed platform 11 near the fixed ring 23, the collection trough 14 is connected to the liquid storage chamber through a pipe, and a flow channel is provided on the edge of the fixed platform 11, the flow channel is connected to the collection trough 14.

[0029] In one specific embodiment of the present invention, the curvature of the extension strip 274 on the side near the outlet 262 is greater than the curvature of the outlet 262, and the curvature of the extension strip 274 on the side near the sliding groove 28 is greater than the curvature of the sliding groove 28.

[0030] Working principle of the invention: The worker places the sheet material on the fixed platform 11, and then the controller controls the hydraulic cylinder to start. The push rod of the hydraulic cylinder then pushes the rotating shaft 12 to move, so that the rotating shaft 12 pushes the fixing component 2 to move during the movement, so that the fixing component 2 presses against the surface of the sheet material, thereby pressing and fixing the sheet material. After the fixing ring 23 presses and fixes the sheet material, the controller controls the electric cylinder to move, and the push rod of the electric cylinder then pushes the moving frame 25 to move, so that the moving frame 25 drives the first chuck 31 and the second chuck 32 to move towards the side closer to the sheet material. The moving frame 25 moves along the axis of the support rod 26. The second chuck 32, influenced by the moving frame 25, causes the positioning column 34 to move towards the side closer to the conical groove 275. As the positioning column 34 moves, it comes into contact with the conical groove 275. Subsequently, the positioning column 34 pushes the conical groove 275 open to both sides, causing the two short rods 272 to separate from each other. As the short rods 272 rotate, they drive the long rod 271 to rotate. As the long rod 271 rotates, it drives the arc plate 273 and the push plate 276 to rotate, causing the two arc plates 273 and the push plate 276 to move to opposite sides. As the push plate 276 moves, it drives the sliding strip 281 to move, causing the two sliding strips 281 to move along the sliding groove 28 to opposite sides, so that the drilling space enclosed by the two long rods 271 is connected to the outside world through the sliding groove 28. When the long rod 271 deflects due to the rotation of the short rod 272, the long rod 271 will drive the extension bars 274 at both ends to rotate, thereby connecting the outlet 262 with the drilling space. Simultaneously, the drilling space is connected to the outside through the sliding groove 28. At this time, the controller starts the water pump, which draws coolant from the storage chamber and transports it through the pipeline to the water supply pipe 261, then through the water supply pipe 261 to the outlet 262, and finally outputs it to the drilling space through the outlet 262. During the coolant transport process, the coolant flows from the intersection of the two long rods 271... The coolant flows towards the side closer to the sliding groove 28, gradually increasing the cross-section of the coolant flow channel and increasing the time the coolant spends in the drilling space. As a result, the coolant can not only cool down the drill bit 33, but also wash away the debris generated by the drill bit 33 during drilling. Some of the coolant flows through the sliding groove 28 to the flow channel set at the edge of the fixed platform 11. After the drill bit 33 drills through the hole, some of the coolant flows through the hole into the collection tank 14. The generated debris will be filtered in the flow channel and the collection tank, while the coolant will flow back into the storage chamber through the pipe.

[0031] As the positioning post 34 descends, because the positioning post 34 is longer than the drill bit, it first opens the conical groove 275, causing the long rod 271 to rotate under the action of the short rod 272. This opens the drilling space, allowing the drill bit 33 to enter the drilling space without obstruction. When the positioning post 34 contacts the surface of the board, because the positioning post 34 is a telescopic post, the moving frame 25 can squeeze the positioning post 34. This allows the positioning post 34 to retract without affecting the moving frame 25 driving the drill bit 33 to drill the board. Subsequently, the controller controls the drilling motor connected to the first chuck 31 to start. The drive shaft of the drilling motor drives the first chuck 31 to rotate. During the rotation of the first chuck 31, the drill bit 33 rotates. As the drill bit 33 rotates, the push rod of the electric cylinder pushes the moving frame 25 to move, causing the moving frame 25 to push the first chuck 31 to one side of the drill bit 33, allowing the drill bit 33 to drill into the board, thus achieving the drilling process. By making the curvature of the extension bar 274 greater than that of the outlet 262 and the sliding groove 28, the extension bar 274 can always limit the opening range of the outlet 262 and the sliding groove 28 when the long rod 271 deflects at different angles. This ensures that the drilling space is always isolated from other areas within the fixed ring 23, thereby limiting the flow area of ​​the coolant. Furthermore, the long rod 271 and the arc plate 273 can block the debris generated during drilling, preventing debris from splashing everywhere.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
