Description

Technical Field

[0001] This utility model belongs to the field of violin case back arc processing technology, specifically relating to a violin case back arc processing device. Background Technology

[0002] A violin body back curve machining device is used to drill holes in the back curve of a violin body. Its principle is typically based on a mechanical transmission and control system. A motor drives the drill bit to rotate, and a precise positioning mechanism ensures the drill bit drills holes in the back curve of the body at preset positions and depths. This device improves drilling accuracy and efficiency, ensuring that the position, size, and depth of each hole meet design requirements, thus guaranteeing the quality and performance of the violin. It is primarily used in violin manufacturing factories and instrument repair workshops. In violin manufacturing factories, it enables large-scale, standardized production, improving efficiency; in instrument repair workshops, it allows for precise drilling of the back curve of violin bodies requiring repair or modification, meeting individualized repair and modification needs.

[0003] Chinese Patent Publication No. CN113211560A relates to the technical field of violin processing devices, and discloses a device for processing the back arc of a violin case. The device includes a base, a PLC controller on the front of the base, a column on the top of the base, a crossbeam on the top of the column, a first motor on one side of the crossbeam, a first screw at one end of the first motor, a first bearing at one end of the first screw, a first threaded sleeve on the outer periphery of the first screw, an electric telescopic rod at the bottom of the first threaded sleeve, a cutting device at the bottom of the electric telescopic rod, and a horizontal and vertical transmission mechanism on the top of the base. This horizontal and vertical transmission mechanism includes a second motor, a second screw at one end of the second motor, a second bearing at one end of the second screw, and a second threaded sleeve on the outer periphery of the second screw.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0028] Please see Figure 1-5 This utility model provides a violin case back arc processing device, comprising:

[0029] Workbench 1 and mounting frame 2;

[0030] Mounting base 3 is set inside mounting frame 2. Mounting frame 2 is U-shaped and located at the top of workbench 1. The bottom of mounting base 3 is provided with electric push rod 4, and the output end of electric push rod 4 is provided with mounting plate 5.

[0031] Positioning disk 6 is located at the bottom of mounting plate 5. Drilling assembly 7 is provided at the bottom of positioning disk 6. Protective cover 8 is provided at the bottom of positioning disk 6 outside of drilling assembly 7. Positioning ring 9 is provided at the bottom of positioning disk 6 outside of protective cover 8.

[0032] Two clamping plates 10 are respectively set on the upper side of the workbench 1. Both clamping plates 10 are located inside the mounting frame 2 and are arranged in a "U" shape. Two transparent protective plates 11 are provided through both sides of the mounting frame 2.

[0033] Specifically, such as Figure 2As shown, a first screw 12 is rotatably connected to the upper end of the mounting frame 2. The mounting base 3 has a threaded hole that is adapted to the first screw 12. The first screw 12 passes through the threaded hole and is threadedly connected to the side wall of the threaded hole. A first motor 13 is provided on one side of the mounting frame 2. The first motor 13 is existing technology and will not be described in detail here. One end of the first screw 12 extends to the outside and is set on the output end of the first motor 13. When the first motor 13 is started, its output end will drive the first screw 12 to rotate, thereby driving the mounting base 3 and the drilling assembly 7 to move, so that it can perform drilling operations on different positions of the back arc of the piano body. This not only saves the time and manpower of readjusting the position of the back arc of the piano body, but also avoids the errors caused by readjustment.

[0034] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, a ventilation slot is provided inside the protective cover 8, and multiple dust suction holes 14 are provided through the inner wall of the ventilation slot. Multiple air extraction holes 15 are provided through the outer side of the upper end of the ventilation slot. An air extraction assembly 16 is provided at the upper end of the mounting frame 2. The air extraction assembly 16 is existing technology and will not be described in detail here. The air extraction assembly 16 is provided with multiple waste and dust filtering components inside. The air extraction end of the air extraction assembly 16 is provided with an air extraction pipe 17 that is adapted to the air extraction hole 15. The air extraction pipe 17 passes through the positioning ring 9 and abuts against the air extraction hole 15.

[0035] By design, when the air extraction component 16 is started, it will draw air from the protective cover 8 through the air extraction pipe 17 and multiple air extraction holes 15 to create a negative pressure state, so that the waste chips and dust generated by drilling can be absorbed through multiple dust suction holes 14, avoiding their impact on the human body and working environment.

[0036] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the positioning disk 6 has an annular groove, and the upper end of the protective cover 8 has an installation ring 18. The upper end of the installation ring 18 is located in the annular groove, and both the inner and outer walls are provided with snap rings 19. The snap rings 19 abut against the bottom of the annular groove. The snap rings 19 provided on the inner and outer walls of the installation ring 18 can limit its position without affecting its rotation.

[0037] Specifically, such as Figure 4As shown, the upper end of the inner wall of the mounting ring 18 is provided with an internal toothed ring 20, and the positioning disk 6 is provided with a drive groove. The drive groove is provided with a second motor 21. The second motor 21 is existing technology and will not be described in detail here. The output end of the second motor 21 is provided with a drive wheel 22 that is adapted to the internal toothed ring 20. One end of the drive wheel 22 extends into the annular groove and meshes with the internal toothed ring 20. When the second motor 21 is started, its output end will drive the drive wheel 22 to rotate. The drive wheel 22 will drive the internal toothed ring 20 and the mounting ring 18 to rotate, thereby driving the protective cover 8 and multiple dust suction holes 14 to rotate, which increases the range that can be absorbed and can comprehensively and effectively treat waste and dust.

[0038] Specifically, such as Figure 3 As shown, a limiting frame 23 is provided inside the mounting frame 2, and the mounting plate 5 is located inside the limiting frame 23. Both sides are provided with snap-fit ​​plates 24. The inner walls of the limiting frame 23 are provided with snap-fit ​​grooves that are adapted to the snap-fit ​​plates 24. The two snap-fit ​​plates 24 are located in the two snap-fit ​​grooves respectively and are slidably connected to the side walls of the snap-fit ​​grooves. Both ends of the limiting frame 23 are provided with connecting plates 25. Through the snap-fit ​​grooves provided on both sides of the inner wall of the limiting frame 23, in conjunction with the snap-fit ​​plates 24 on both sides of the mounting plate 5, the electric push rod 4 can drive the limiting frame 23 to move up and down without affecting the movement of the mounting plate 5 and the drilling assembly 7.

[0039] Specifically, such as Figure 2 and Figure 3 As shown, one end of each of the two connecting plates 25 passes through both sides of the mounting frame 2, and each is equipped with a guide rod 26. One side of each of the two transparent protective plates 11 on both sides is provided with a guide groove 27 that matches the guide rod 26. The guide groove 27 is inclined. The two ends of the two guide rods 26 are located in the two guide grooves 27 on both sides and are slidably connected to the side wall of the guide groove 27. When the limiting frame 23 moves, it will drive the connecting plates 25 and guide rods 26 on both sides to move up and down respectively. With the inclined guide groove 27, the limiting frame 23 can drive the transparent protective plates 11 on both sides to move in opposite directions when it moves up and down, so as to conveniently close the mounting frame 2, effectively prevent the waste chips generated by drilling from splashing outwards, and ensure the safety of the violin case back arc processing device. Example

[0040] Please see Figure 1-5 This utility model provides a violin case back arc processing device, comprising:

[0041] Workbench 1 and mounting frame 2;

[0042] Mounting base 3 is set inside mounting frame 2. Mounting frame 2 is U-shaped and located at the top of workbench 1. The bottom of mounting base 3 is provided with electric push rod 4, and the output end of electric push rod 4 is provided with mounting plate 5.

[0043] Positioning disk 6 is located at the bottom of mounting plate 5. Drilling assembly 7 is provided at the bottom of positioning disk 6. Protective cover 8 is provided at the bottom of positioning disk 6 outside of drilling assembly 7. Positioning ring 9 is provided at the bottom of positioning disk 6 outside of protective cover 8.

[0044] Two clamping plates 10 are respectively set on the upper side of the workbench 1. Both clamping plates 10 are located inside the mounting frame 2 and are arranged in a "U" shape. Two transparent protective plates 11 are provided through both sides of the mounting frame 2.

[0045] Specifically, such as Figure 2 As shown, a second screw 28 is provided through the upper end of each of the two clamping plates 10, and a fixing plate 29 is rotatably connected to the bottom end of each of the two second screws 28.

[0046] Its design allows the fixing plate 29 to move up and down by rotating the second screw 28, enabling it to be fixed on the back arc of violin cases of different sizes and specifications, achieving precise clamping and stable processing, thus making the violin case back arc processing device more versatile.

[0047] See Figure 1-5 When using the violin case back arc processing device to drill holes in the violin case back arc, firstly, the two ends of the violin case back arc are placed in the two clamping plates 10 respectively, and the two second screws 28 are rotated to drive the two fixing plates 29 to abut against the upper sides of the violin case back arc. Then, the first motor 13 is started according to the position of the drilling. The output end of the first motor 13 will drive the first screw 12 to rotate, and the first screw 12 will drive the mounting base 3 to move horizontally, thereby adjusting the position of the drilling assembly 7 so that it can process different positions of the violin case back arc.

[0048] During the drilling process, the electric push rod 4 is activated. The output end of the electric push rod 4 will drive the mounting plate 5 and the positioning plate 6 to move downwards. The positioning plate 6 will drive the drilling assembly 7 to move downwards to drill the back arc of the piano case. During the drilling process, a large amount of waste chips and dust will be generated. It is necessary to activate the air extraction assembly 16. The air extraction assembly 16 will extract the air in the protective cover 8 through the air extraction pipe 17 and multiple air extraction holes 15 to create a negative pressure state. Thus, the waste chips and dust generated during drilling can be absorbed through multiple dust suction holes 14. Then, the second motor 21 is activated. The output end of the second motor 21 will drive the drive wheel 22 to rotate. The drive wheel 22 will drive the internal gear ring 20 to rotate. The internal gear ring 20 will drive the mounting ring 18 and the protective cover 8 to rotate, thereby driving the multiple dust suction holes 14 to rotate, which improves the effect of absorbing and treating waste chips and dust.

[0049] As the mounting plate 5 moves downward, it will drive the limiting frame 23 downward through the two snap-fit ​​plates 24. The limiting frame 23 will drive the two connecting plates 25 and the two guide rods 26 downward. In conjunction with the inclined guide groove 27, it can simultaneously drive the two transparent protective plates 11 on both sides to move in opposite directions, thereby closing the mounting frame 2 and preventing the waste generated during processing from splashing outward, thus avoiding harm to human health and pollution of the working environment. This makes the violin case back arc processing device more practical.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
