Description

Technical Field

[0001] The utility model relates to the technical field of guitar manufacturing, in particular to automatic processing equipment for the curved surface contour of a guitar. Background Art

[0002] Classical guitar, as a musical instrument with a long history and deeply loved by people, has a unique neck design with hard and non-uniform lines. This design not only gives the guitar a unique artistic beauty, but also puts forward high requirements on the processing technology in the guitar manufacturing process. In the guitar manufacturing process, the surface contour processing of the neck is a crucial link, and its processing quality directly affects the appearance and sound quality of the guitar.

[0003] The traditional method of processing guitar surfaces mainly relies on workers to manually grind with hand-held grinders. This method has many shortcomings. First, it requires workers to have extremely high technical requirements, and requires workers to have rich experience and superb craftsmanship to ensure that the processed guitar surface contour meets the design requirements. However, such skilled workers are often difficult to train in large numbers, and the labor cost is high, which is not conducive to large-scale production and cost control of guitar manufacturing.

[0004] Secondly, manual polishing is inefficient and takes a long time, which results in low production efficiency of guitar manufacturing and cannot meet the market demand. At the same time, the wood chips scattered during the polishing process not only affect the working environment, but also threaten the health of workers. Workers who inhale wood chips for a long time are prone to respiratory diseases, which seriously damages their health. Utility Model Content

[0034] See also Figure 1-3 The utility model is an automatic processing device for guitar curved surface contour, comprising the following components:

[0035] The frame 1 is provided with a work surface 1 2 and a work surface 2 3 on the top, and the work surface 1 2 and the work surface 2 3 are arranged vertically, and a vertical rod 6 is arranged on a front side of the work surface 1 2;

[0036] An X-axis moving platform mechanism is installed on the work surface 1 2, and includes an X-direction translation servo motor 4 and an X-direction lead screw 5. The X-direction translation servo motor 4 is fixedly installed on the right end of the work surface 1 2, the X-direction lead screw 5 is rotationally connected to the frame 1, and the output shaft of the X-direction translation servo motor 4 is fixedly connected to one end of the X-direction lead screw 5;

[0037] The Y-axis moving platform mechanism is installed on the work surface 2 3, including a Y-direction translation servo motor 8 and a Y-direction lead screw 9. The Y-direction translation servo motor 8 is fixedly installed in front of the work surface 2 3, and the output shaft of the Y-direction translation servo motor 8 is fixedly connected to one end of the Y-direction lead screw 9, and the other end of the Y-direction lead screw 9 is rotatably installed on the work surface 2 3;

[0038] The Z-axis moving platform mechanism includes a Z-direction translation servo motor 15 and a Z-direction lead screw 16. The Z-direction translation servo motor 15 is fixedly mounted on the vertical rod 6. The output shaft of the Z-direction translation servo motor 15 is fixedly connected to one end of the Z-direction lead screw 16. The vertical rod 6 is sleeved on the X-direction lead screw 5.

[0039] The clamping table 7 includes a vacuum pump 11, a vacuum suction cup 12, an adsorption plate 10, and a vacuum generating chamber evenly arranged at the center of the plate. A vacuum tube is installed in the vacuum generating chamber and connected to the vacuum pump 11. The vacuum suction cup 12 is connected to the vacuum generating chamber through a vacuum channel.

[0040] The spindle processing mechanism includes a rotary servo motor 17, the rotary servo motor 17 is sleeved on the Z-direction screw rod 16, and the clamping table 7 is sleeved on the Y-direction screw rod 9, and a milling cutter 18 is provided at the output end of the servo motor 17;

[0042] The preferred solution of the above-mentioned automatic processing equipment for guitar curved surface contour is:

[0043] Working principle of the clamping table 7 and the adsorption plate 10:

[0044] The guitar neck is placed on the adsorption plate 10. The adsorption plate 10 is designed with a vacuum channel and a vacuum generating chamber. When the vacuum pump 11 is started, vacuum is drawn through these two components, thereby forming a negative pressure on the surface of the adsorption plate 10, so that the guitar neck fits tightly on the adsorption plate 10 to achieve preliminary fixation.

[0045] After the guitar neck is vacuum-adsorbed, the clamping cylinders 13 at both ends of the adsorption plate 10 start to work. The output end of the clamping cylinder 13 drives the clamping block 14 to move, so that the clamping block 14 approaches and tightly clamps the guitar neck. This step further enhances the fixing effect of the guitar neck, ensuring that it will not be displaced or shaken during the processing.

[0046] Working principle of rotary servo motor 20:

[0047] A rotary servo motor 20 is installed at the bottom of the adsorption plate 10. After receiving the command from the control system, the motor starts to work and drives the clamping table 7 to rotate through its conveying end. The rotation angle can be precisely controlled as needed, and can reach at least 180°, so as to facilitate the processing of different parts of the guitar neck.

[0048] It is worth noting that the rotary servo motor 20 is mounted on the Y-direction lead screw 9, which means that while rotating, it can also move along the Y-direction, thereby increasing the processing flexibility of the equipment.

[0049] Working principle of work surface and mobile platform mechanism:

[0050] A slide groove 19 is provided on the front side of the work surface 1 2, and the vertical rod 6 is slidably connected to the slide groove 19 through a slide rod. This design allows the equipment to be flexibly moved in the horizontal direction during operation to adapt to different processing requirements.

[0051] A plurality of work surfaces 2 are arranged at one end of the frame 1, and a Y-axis moving platform mechanism is installed on each work surface 2. The Y-axis moving platform mechanism can move precisely in the Y-axis direction, and at the same time, it cooperates with the vertically arranged Z-axis moving platform mechanism to achieve precise positioning in three-dimensional space.

[0052] By precisely controlling the X-axis, Y-axis and Z-axis moving platform mechanisms through the control system, the position of the spindle machining mechanism can be adjusted so that the guitar neck can be cut according to a preset machining trajectory.

[0053] Working principle of the processing process:

[0054] First, the guitar neck to be processed is placed on the adsorption plate 10 of the clamping table 7 .

[0055] Then, the vacuum pump 11 is started to perform vacuum adsorption, and the clamping cylinder 13 is started to perform mechanical clamping.

[0056] Next, the control system starts the rotary servo motor 20 to rotate the guitar neck to a suitable processing position.

[0057] On this basis, the control system controls the moving platform mechanism of each axis and the spindle processing mechanism to perform cutting processing according to the preset processing trajectory.

[0058] Finally, after the processing is completed, the control system stops the movement of each component, releases the clamping table 7, and removes the processed guitar neck.

[0059] Through this series of work processes, the equipment can realize automatic processing of the guitar surface contour, improving processing accuracy and efficiency.

[0060] The working principle of this automatic processing equipment for guitar surface contour is as follows:

[0061] The equipment is mainly composed of a frame 1, an X-axis moving platform mechanism, a Y-axis moving platform mechanism, a Z-axis moving platform mechanism, a clamping table 7, a spindle processing mechanism and a control system.

[0062] The frame 1 serves as the supporting structure of the entire device, and a vertically arranged work surface 1 2 and a work surface 2 3 are arranged on the top. A vertical rod 6 is arranged on the front side of the work surface 1 2 to support the Z-axis moving platform mechanism.

[0063] The X-axis moving platform mechanism is installed on the work surface 2, and the X-direction lead screw 5 is driven by the X-direction translation servo motor 4 to move in the horizontal direction.

[0064] The Y-axis moving platform mechanism is installed on the work table 2 3, and the Y-direction lead screw 9 is driven by the Y-direction translation servo motor 8 to move in a direction perpendicular to the X-axis.

[0065] The Z-axis moving platform mechanism includes a Z-direction translation servo motor 15 and a Z-direction screw 16, which are fixed on the vertical rod 6, and the vertical rod 6 can move along the X-direction screw 5. The Z-direction translation servo motor 15 drives the Z-direction screw 16 to perform vertical lifting movement.

[0066] The clamping table 7 is the core part of the equipment, including a vacuum pump 11, a vacuum suction cup 12, an adsorption plate 10 and a vacuum generating chamber. The guitar neck to be processed is placed on the adsorption plate 10, and the vacuum pump 11 draws vacuum through the vacuum channel and the vacuum generating chamber, so that the guitar neck is tightly adsorbed on the adsorption plate 10. At the same time, the clamping cylinders 13 at both ends of the adsorption plate 10 drive the clamping blocks 14 to mechanically clamp the guitar neck to ensure stability during the processing.

[0067] The spindle processing mechanism includes a rotary servo motor 17 and a milling cutter 18, which are used to drive the processing tool to perform cutting processing. The rotary servo motor 17 is sleeved on the Z-direction screw rod 16 and can move up and down with the Z-axis moving platform mechanism.

[0068] The control system is the "brain" of the entire device, responsible for controlling the movement of the X-axis, Y-axis, and Z-axis moving platform mechanisms, the clamping table 7, and the spindle processing mechanism. According to the preset processing trajectory, the control system accurately controls the movement of each component, so that the spindle processing mechanism cuts the guitar neck according to the predetermined path.

[0069] The processing flow is as follows: first, place the guitar neck on the adsorption plate 10 of the clamping table 7; then, start the vacuum pump 11 and the clamping cylinder 13 to fix it; then, start the rotary servo motor 20 through the control system to adjust the processing angle of the guitar neck; then, according to the preset processing trajectory, the control system controls the moving platform mechanism of each axis to make the spindle processing mechanism cut the guitar neck; finally, after the processing is completed, the control system stops the movement of each component, releases the clamping table 7, and removes the processed guitar neck.

[0070] Through this series of working principles and processes, the equipment can realize automatic processing of the guitar surface contour, improving processing accuracy and efficiency.

[0071] The control system in the utility model can adopt conventional electrical control equipment.

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
