Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, and in particular to a woodworking engraving machine with a workpiece clamping device. Background Technology

[0002] In the modern woodworking industry, CNC woodworking engraving machines play a crucial role as a key mechanical processing equipment. With their high-precision processing capabilities, they can directly import pre-designed processing drawings and efficiently complete diverse processing tasks such as relief carving, flat carving, openwork carving, and cutting preset shapes for wood materials such as boards and furniture. As a result, CNC woodworking engraving machines have been widely used in the furniture manufacturing field, greatly improving the efficiency and quality of furniture production.

[0003] However, most current wood carving machines can only clamp wood of fixed dimensions in a simple way during application. They are unable to clamp wood flexibly and accurately according to its length, width and thickness. This method of clamping results in a large limitation of the carving machine. Moreover, the stability of the wood board is difficult to be effectively guaranteed during processing, which seriously affects the accuracy and quality of the carving operation. Summary of the Invention

[0004] The problem this invention aims to solve is to provide a wood carving machine with a workpiece clamping device that can flexibly and accurately fix wood panels according to their length, width, and thickness.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a woodworking engraving machine with a workpiece clamping device, including a worktable, an adjustment component installed inside the worktable, a clamping component installed above the worktable, a movable arm provided above the worktable and installed on the side of the worktable, an engraving component installed on the top of the movable arm, the clamping component including two L-shaped placement plates, the two L-shaped placement plates being symmetrically distributed above the worktable, each of the tops of the two L-shaped placement plates having a limiting groove, each of the two limiting grooves having two limiting sliders slidably connected inside, the upper surfaces of the four limiting sliders extending to the tops of the two L-shaped placement plates, and each of the upper surfaces of the four limiting sliders being fixedly connected to a fixing plate.

[0006] Preferably, in the above-mentioned woodworking engraving machine with workpiece clamping device, hydraulic rods are installed on the top of the four fixed plates, the output end of the hydraulic rods is fixedly connected to a lower pressure plate, and a soft pad is fixedly connected to the bottom surface of the lower pressure plate.

[0007] Preferably, in the above-mentioned woodworking engraving machine with workpiece clamping device, the upper surface of the worktable is fixedly connected to two support guide rails, the two support guide rails are symmetrically distributed on both sides of two L-shaped placement plates, and movable sliders are fixedly connected to both sides of the two L-shaped placement plates. The four movable sliders are slidably connected inside the two support guide rails.

[0008] Preferably, in the above-mentioned woodworking engraving machine with workpiece clamping device, the adjusting component includes a bidirectional lead screw, which is rotatably connected to the inner wall of the worktable. A bevel gear is fixedly connected to the outer surface of the bidirectional lead screw. A motor housing is fixedly connected to the bottom surface of the worktable. A motor is fixedly connected inside the motor housing. The output end of the motor extends into the interior of the worktable. A bevel gear is fixedly connected to the output end of the motor. The bevel gear and the bevel gear mesh with each other. Two connecting blocks are threadedly connected to the outer surface of the bidirectional lead screw, and the two connecting blocks are symmetrically distributed on the outer surface of the bidirectional lead screw.

[0012] This invention, through the cooperation of the adjusting component, clamping component, and through groove, and the coordination of the motor, bevel gear two, bevel gear one, double-acting screw, and connecting block in the adjusting component, can flexibly adjust the distance between the two L-shaped placement plates according to the length of the wood, achieving initial positioning of the wood. Using the limiting slide groove and limiting slider, the distance between the two fixed plates can be adjusted according to the width of the wood. Then, the hydraulic rod drives the lower pressure plate and soft pad to clamp the wood. It can provide stable clamping from all directions according to the length, width, and thickness of the wood, solving the problem that existing engraving machines cannot flexibly and accurately clamp wood of different lengths, widths, and thicknesses. This greatly expands the application range of the engraving machine and improves the flexibility and versatility of processing.

This ensures stability when adjusting the spacing of the L-shaped placement plates. When the pressure plate moves downward under the action of the hydraulic rod, the soft pad prevents excessive downward pressure from directly acting on the surface of the wood and causing damage, thus protecting the wood.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0020] like Figures 1 to 4As shown, a woodworking engraving machine with a workpiece clamping device includes a worktable 1, an adjustment component 2 installed inside the worktable 1, a clamping component 3 installed above the worktable 1, a movable arm 5 provided above the worktable 1 and installed on the side of the worktable 1, and an engraving component 6 installed on the top of the movable arm 5. The clamping component 3 includes two L-shaped placement plates 301, which are symmetrically distributed above the worktable 1. Each of the two L-shaped placement plates 301 has a limiting groove 302 on its top. Each of the two limiting grooves 302 has two limiting sliders 303 slidably connected inside. The upper surfaces of the four limiting sliders 303 extend to the top of the two L-shaped placement plates 301, and each of the four limiting sliders 303 has a fixed plate 304 fixedly connected to its upper surface.

[0021] The workbench 1, as the basic load-bearing component, provides a platform for the installation and operation of other components. It contains an adjustment component 2 for adjusting the positions of the two L-shaped placement plates 301 in the clamping component 3 to accommodate wood of different lengths. The clamping component 3, mounted above the workbench 1, is crucial for stably clamping the wood. A movable arm 5, mounted on the side of the workbench 1, moves along a specific track under the control of an external CNC system. A carving component 6, also controlled by an external CNC system, is mounted on top of the movable arm 5 and can move on top of it. The carving component 6 is driven by the movable arm 5. It can perform carving operations on clamped wood. The two L-shaped placement plates 301 in the clamping assembly 3 are symmetrically distributed above the worktable 1. The top of each L-shaped placement plate 301 is provided with a limiting groove 302. The limiting groove 302 is long and narrow. Two limiting sliders 303 are slidably connected inside each limiting groove 302. The limiting sliders 303 can slide smoothly in the limiting groove 302. The upper surfaces of the four limiting sliders 303 extend to the top of the L-shaped placement plate 301, and the upper surfaces of the four limiting sliders 303 are fixedly connected with a fixing plate 304. The movement of the limiting sliders 303 can change the position of the fixing plate 304.

[0022] Hydraulic rods 305 are installed on the top of the four fixed plates 304. The output end of the hydraulic rods 305 is fixedly connected to the lower pressure plate 306, and the bottom surface of the lower pressure plate 306 is fixedly connected to the soft pad 307.

[0023] The hydraulic rod 305 installed on the top of the fixed plate 304 can be controlled by an external control switch. The lower pressure plate 306 is fixedly connected to the output end of the hydraulic rod 305 and a soft pad 307 is fixedly connected to the bottom surface. The soft pad 307 is usually made of flexible materials such as rubber or silicone. When the lower pressure plate 306 is moved down by the hydraulic rod 305 to clamp and fix the wood, the soft pad 307 can protect the wood.

[0024] The upper surface of the workbench 1 is fixedly connected to two support rails 308. The two support rails 308 are symmetrically distributed on both sides of the two L-shaped placement plates 301. The two sides of the two L-shaped placement plates 301 are fixedly connected to movable sliders 309. The four movable sliders 309 are slidably connected inside the two support rails 308.

[0025] Two support rails 308 are mounted on the upper surface of the workbench 1 and are symmetrically distributed on both sides of the two L-shaped placement plates 301. Movable sliders 309 are fixedly connected to both sides of the two L-shaped placement plates 301. The L-shaped placement plates 301 are slidably connected to the inside of the two support rails 308 through the two movable sliders 309. The support rails 308 are configured to provide guidance and stable support for the movement of the L-shaped placement plates 301.

[0026] The adjustment assembly 2 includes a bidirectional lead screw 201, which is rotatably connected to the inner wall of the worktable 1. A bevel gear 202 is fixedly connected to the outer surface of the bidirectional lead screw 201. A motor housing 203 is fixedly connected to the bottom surface of the worktable 1. A motor 204 is fixedly connected inside the motor housing 203. The output end of the motor 204 extends into the interior of the worktable 1. A bevel gear 205 is fixedly connected to the output end of the motor 204. The bevel gear 202 and the bevel gear 205 are meshed together. Two connecting blocks 206 are threadedly connected to the outer surface of the bidirectional lead screw 201. The two connecting blocks 206 are symmetrically distributed on the outer surface of the bidirectional lead screw 201. Two through slots 4 are opened on the upper surface of the worktable 1. The two connecting blocks 206 pass through the two through slots 4 and extend to the top of the worktable 1. Two L-shaped placement plates 301 are fixedly connected to the upper surfaces of the two connecting blocks 206.

[0027] The bidirectional lead screw 201 in the adjusting assembly 2 is rotatably connected to the inner wall of the worktable 1. A bevel gear 202 is fixedly connected to its outer surface. The motor housing 203 fixedly connected to the bottom surface of the worktable 1 can provide protection for the motor 204 fixedly connected inside. The motor 204 is controlled by an external control switch. The operation of the motor 204 can drive the bevel gear 205 to rotate. Through the meshing connection between the bevel gear 202 and the bevel gear 205, the bidirectional lead screw 201 is driven to rotate. Two connecting blocks 206 threaded to the outer surface of the bidirectional lead screw 201 are respectively inserted into two through slots 4 and extend to the top of the worktable 1. The connecting blocks 206 can move in the through slots 4. The through slots 4 limit the movement of the connecting blocks 206, so that they can only move along the direction of the through slots 4. Therefore, when the bidirectional lead screw 201 rotates, it will drive the two connecting blocks 206 to move closer or further apart. The two L-shaped placement plates 301 move with the movement of the two connecting blocks 206, so that the distance between the two L-shaped placement plates 301 can be adjusted.

[0028] The bottom surface of the workbench 1 is fixedly connected to four support legs 7, which are distributed in a rectangular shape on the bottom surface of the workbench 1.

[0029] The four support legs 7 are arranged in a rectangular shape on the bottom surface of the worktable 1, so that the worktable 1 can be placed stably.

[0030] Working Principle: When using this engraving machine, the motor 204 is first started via an external control switch. The motor 204 drives the second bevel gear 205 to rotate. Since the first bevel gear 202 meshes with the second bevel gear 205, the bidirectional lead screw 201 rotates. During the rotation of the bidirectional lead screw 201, the two connecting blocks 206 threaded to its outer surface move closer to each other along the axial direction of the bidirectional lead screw 201 under the limiting action of the two through slots 4. The distance between the two L-shaped placement plates 301 is adjusted reasonably according to the length of the wood. When the two L-shaped placement plates 301 move, the movable sliders 309 fixedly connected to both sides of the L-shaped placement plates 301 slide within the support guide rails 308 fixedly connected to the upper surface of the worktable 1, ensuring more stable movement of the L-shaped placement plates 301. At the same time, the support guide rails 308 also provide support for the L-shaped placement plates 301. Additional support is provided, and then the wood is placed on two L-shaped placement plates 301. The two L-shaped placement plates 301 are then controlled to move closer together, initially clamping the wood according to its length. Subsequently, according to the width of the wood, the two fixed plates 304 at the top of the L-shaped placement plates 301 are adjusted to a suitable distance using the sliding cooperation of the limiting groove 302 and the limiting slider 303. Then, the hydraulic rod 305 is activated, and the output end of the hydraulic rod 305 drives the lower pressure plate 306 to move downward. The soft pad 307 on the bottom surface of the lower pressure plate 306 contacts the wood first. As the hydraulic rod 305 continues to press down, the soft pad 307 tightly adheres to the surface of the wood, and then the wood is stably clamped according to its thickness. After the wood is clamped and positioned, the external CNC system controls the moving arm 5 to drive the top carving component 6 to perform carving operations on the wood according to the preset program.
