[0002] Wood carving machines are mainly used for wood processing, crystal, copper, aluminum, etc., to make them more aesthetically pleasing. They are widely used in furniture manufacturing, decoration, handicrafts and other industries. As the market's requirements for the quality and precision of wood carving products continue to increase, the demand for carving machines is also increasing.

[0003] In existing wood carving machine technology, the workpiece fixing method is relatively traditional, mostly using simple mechanical clamps. It is difficult to accurately control the clamping force. If the clamping force is too small, the workpiece is prone to displacement during the carving process, resulting in deviation of the carving pattern and reduced accuracy. If the clamping force is too large, the workpiece may be deformed, affecting the carving effect or even damaging the workpiece, which has certain shortcomings. Summary of the Invention

[0004] The problem this invention aims to solve is to provide a wood carving machine with carving quality detection function that can accurately control clamping force, monitor workpiece deformation in real time, and effectively improve carving quality.

[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 4 As shown, a wood carving machine with carving quality detection function includes a worktable 1. The worktable 1 is made of high-strength cast iron, which has good rigidity and stability and can effectively reduce the impact of vibration generated during carving on the workpiece and carving accuracy. A controller 2 is fixedly installed on its outer surface. The controller 2 is an industrial-grade programmable logic controller (PLC), which has powerful data processing capabilities and stable operating performance. It can accurately receive and process various sensor signals and quickly output control commands.

[0021] A set of clamping mechanisms 3 is provided above the workbench 1. The clamping mechanisms 3 are used to securely fix the main body of the plate 4.

[0022] The mounting bracket 301 of the clamping mechanism 3 is welded from high-quality carbon steel, with a sturdy and durable structure. It is tightly fixed to the outer surface of the worktable 1 by bolts to ensure that it will not loosen during operation. A motor 302 is fixedly mounted on the outer surface of the mounting bracket 301. The motor 302 is a high-precision servo motor with fast response speed and high control accuracy. A threaded cylinder 303 is fixedly connected to its output end. The threaded cylinder 303 is made of high-strength alloy steel and has a finely threaded surface with high thread accuracy. It is rotatably connected to the inner wall of the mounting bracket 301 to ensure that it can rotate smoothly and steadily under the drive of the motor 302.

[0023] The inner wall of the threaded cylinder 303 is threadedly connected to an adjusting screw 304. The adjusting screw 304 is also made of high-strength alloy steel and has a tight fit with the threaded cylinder 303, resulting in high transmission efficiency. The outer surface of the adjusting screw 304 is rotatably connected to the inner wall of the fixed frame 305 through a high-precision bearing. This connection method can reduce frictional resistance and ensure that the fixed frame 305 can move stably along its axial direction when the adjusting screw 304 rotates.

[0024] The fixing frame 305 is made of aluminum alloy, which is lightweight but strong enough. Its inner wall is in contact with the outer surface of the plate body 4, and pressure sensors 9 are embedded in the inner wall at equal intervals. The pressure sensors 9 are high-precision strain gauge pressure sensors, which can accurately measure the clamping force of the fixing frame 305 on the plate body 4, providing real-time and reliable data support for precise control of the clamping force.

[0025] A set of guide slide rods 306 are fixedly connected to the outer surface of the fixed frame 305. The guide slide rods 306 are made of chrome-plated round steel, with a smooth surface, high hardness, and good wear resistance. A limit plate 307 is slidably connected to the outer surface of the guide slide rods 306. The limit plate 307 is made of stainless steel and has a reasonable shape design, which can effectively limit the movement range of the fixed frame 305 and prevent excessive movement from causing equipment damage or safety accidents. The inner wall of the limit plate 307 is rotatably connected to the outer surface of the threaded cylinder 303 through rolling bearings. In this way, when the threaded cylinder 303 rotates, the limit plate 307 can stably guide and limit the guide slide rods 306. At the same time, its bottom surface is fixedly connected to the upper surface of the worktable 1 through bolts, which further enhances the stability of the entire clamping mechanism 3.

[0026] The main body of the plate 4 is placed on top of the workbench 1. The main body of the plate 4 needs to be pre-treated before carving to ensure that the surface is flat and smooth so as to better contact the fixing frame 305 and ensure the clamping effect.

[0027] Strain gauges 5 are attached to the upper surface of the main body 4 of the plate. The strain gauges 5 are foil strain gauges, which have the characteristics of high precision and good stability. They can detect the minute deformation of the plate in real time during the engraving process. Once an abnormal deformation is detected, the signal is immediately transmitted to the controller 2 so that the engraving parameters can be adjusted in time to ensure the engraving quality.

[0028] A position adjustment mechanism 6 is provided above the workbench 1 to precisely adjust the position of the engraving tool 8.

[0029] The movable frame 601 of the workstation adjustment mechanism 6 is made of aluminum alloy, which is lightweight and high-strength. It is slidably connected to the outer surface of the worktable 1, enabling smooth sliding. The slider 606 is made of wear-resistant engineering plastic, which has good sliding performance and low friction coefficient, reducing the resistance when the slider 606 moves and improving the adjustment accuracy.

[0030] A hydraulic telescopic rod 7 is fixedly installed on the outer surface of the slider 606. The hydraulic telescopic rod 7 is made of high-strength alloy steel and has good internal sealing performance, which can provide stable telescopic power. A carving tool 8 is fixedly installed at the bottom of the hydraulic telescopic rod 7. The carving tool 8 is driven by a rotating motor. The carving tool 8 can be made of different materials and shapes according to different carving needs. For example, carbide tools are suitable for cutting wood with high hardness. Their blades are sharp and wear-resistant, which can ensure that the carved patterns have clear lines and high precision.

[0031] The workstation adjustment mechanism 6 also includes a second motor 602 fixedly installed on the outer surface of the worktable 1. The second motor 602 is a high-performance stepper motor with high step angle accuracy and smooth operation. Its output end is fixedly connected to a lead screw 603. The lead screw 603 is a ball screw with a hardened surface, high hardness, high transmission efficiency and high precision. It is screwed to the moving frame 601. The outer surface of the lead screw 603 is rotatably connected to the inner wall of the worktable 1 through a high-precision bearing. When the second motor 602 starts, the lead screw 603 rotates, driving the moving frame 601 to slide precisely along the outer surface of the worktable 1, thereby realizing the horizontal position adjustment of the engraving tool 8.

[0032] A motor 604 is fixedly mounted on the outer surface of the movable frame 601. The motor 604 is a stepper motor, and its output end is fixedly connected to a lead screw 605. The lead screw 605 is also a ball screw and is screwed to the slider 606. The outer surface of the lead screw 605 is rotatably connected to the inner wall of the movable frame 601 through a high-precision bearing. When the motor 604 drives the lead screw 605 to rotate, it can precisely control the sliding of the slider 606 on the inner wall of the movable frame 601, thereby driving the hydraulic telescopic rod 7 and the engraving tool 8 to move in the horizontal direction, so as to realize the precise position adjustment of the engraving tool 8 in the horizontal direction.

[0033] Through the coordinated operation of components such as motor 2 (602), lead screw 1 (603), motor 3 (604), lead screw 2 (605), and slider 606, the engraving tool 8 can achieve high-precision position adjustment in the horizontal and vertical directions, meeting the strict requirements of various complex engraving patterns on tool position, greatly expanding the processing capacity and application range of the engraving machine, and enhancing the practical value of the equipment.

[0034] Working Principle: When this wood carving machine is working, the main body 4 of the board is first placed on the worktable 1 and fixed by the clamping mechanism 3. The motor 1 302 starts, driving the threaded cylinder 303 to rotate. The adjusting screw 304, which is threaded to the threaded cylinder 303, moves accordingly, causing the fixed frame 305 to slide along the guide slide rod 306, so that the inner wall of the fixed frame 305 is in close contact with the outer surface of the main body 4 of the board. The pressure sensor 9 on the inner wall of the fixed frame 305 monitors the clamping force in real time to ensure that the clamping force is moderate. At the same time, the strain gauge 5 attached to the upper surface of the main body 4 of the board detects the deformation of the board in real time during the carving process. The position adjustment mechanism 6 can adjust the position of the carving tool 8. The motor 2 602 drives the lead screw 1 603 to rotate, causing the moving frame 601 to move. Sliding along the outer surface of the worktable 1, motor 3 604 drives lead screw 2 605 to rotate, controlling slider 606 to slide on the inner wall of moving frame 601, which in turn drives hydraulic telescopic rod 7 and engraving tool 8 to follow the movement, realizing the horizontal position adjustment of engraving tool 8. When engraving is required, hydraulic telescopic rod 7 extends, pushing engraving tool 8 close to the plate body 4 and moving vertically to engrave plate body 4. During the engraving process, if strain gauge 5 detects abnormal deformation of plate body 4, the signal will be transmitted to controller 2. Controller 2 controls components such as motor 1 302, motor 2 602, motor 3 604 and hydraulic telescopic rod 7 according to the preset program, adjusting parameters such as feed rate and engraving speed of engraving tool 8 to ensure engraving quality.
