[0002] The harmonica is a small-sized keyboard wind instrument with good pitch and excellent melody. It is classified in the same category as the harmonica, both of which are free reed instruments. The harmonica uses a piano-like keyboard and produces sound by blowing the vibrating reeds through the side mouthpiece. Therefore, it can also be regarded as a wind keyboard instrument. The harmonica's range is generally three octaves, and it can produce rich harmonic effects. In addition, it has good harmonic ability and is widely used in various types of music. When producing and processing the harmonica, the harmonica needs to be effectively fixed. Traditional clamping devices are often unable to fix harmonicas of different specifications when used.

[0003] The Chinese patent publication number CN213946178U discloses a clamping and fixing device for processing a harmonica.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0022] See also Figure 1-Figure 11The embodiment of the present invention provides a technical solution: a clamping and fixing device for harmonica processing, including a support seat 1, and also including a connecting sleeve 22, the connecting sleeve 22 is fixed to the outside of the support seat 1, preferably the connecting sleeve 22 is welded to the support seat 1, and an outer support ring 3 is fixed to the outside of the connecting sleeve 22, an inner support ring 4 is fixed to the front surface of the outer support ring 3, preferably the inner support ring 4 and the outer support ring 3 are integrally cast, a rotating shaft 25 is rotatably installed in the connecting sleeve 22, under the setting of the connecting sleeve 22, the stability of the rotating shaft 25 during rotation is improved, and an inner shaft 33 is rotatably installed in the rotating shaft 25, and the rotation speed of the inner shaft 33 is different from that of the rotating shaft 25.

[0023] To facilitate the fixation of the harmonica shell 9, the clamping and fixing device for harmonica processing provided in this embodiment also includes a transmission box 10, which is installed at one end of the rotating shaft 25, and frame frames 11 are rotatably installed on both sides of the transmission box 10. Preferably, the side of the frame frame 11 away from the transmission box 10 and the front surface are both in an open state to facilitate the installation and fixation of the harmonica shell 9. It is particularly important to note that the back side of the frame frame 11, that is, the side close to the outer support ring 3, is in a sealed state, which is used for limiting the position of the harmonica shell 9 after installation. The frame frame 11 is rotated to drive the harmonica shell 9 to rotate, thereby achieving angle adjustment of the harmonica shell 9. To achieve the fixation of one end of the harmonica shell 9, a pressure plate 17 is slidably installed inside the frame frame 11, and one end of the harmonica shell 9 is pressed against the inner side of the frame frame 11 by the pressure plate 17 to achieve the fixation of one end of the harmonica shell 9.

[0024] In addition, the clamping and fixing device for harmonica processing provided in this embodiment also includes a slide 6, which is slidably arranged on the inner support ring 4, and there are two slides 6. In addition, the rotation speed of the slide 6 is the same as the rotation speed of the rotating shaft 25. Brackets 7 are installed on the outer sides of the two slides 6. Through the arrangement of double slides 6 and double brackets 7, and then through the cooperation of two frame frames 11, the double harmonica shells 9 can be synchronously fixed, and the number of clamping is increased to improve the subsequent processing efficiency of the harmonica shells 9. In order to achieve the limitation of the harmonica shell 9 away from one end of the frame frame 11, a first fastening bolt is threadedly connected to the bracket 7. 8. One end of the first fastening bolt 8 extends to the inner side of the bracket 7 and is rotatably installed with a contact plate 14. Preferably, the contact plate 14 and the first fastening bolt 8 are rotatably connected via a bearing. The bearing allows the contact plate 14 to be rotatably connected to the first fastening bolt 8 so that the contact plate 14 interferes with the harmonica shell 9 when it rotates, thereby improving the rationality of the equipment design. The harmonica shell 9 is fixed between the first contact plate 14 and the frame 11 on the same side, and the contact plate 14 is pushed to move by the first fastening bolt 8 so that the harmonica shell 9 is clamped between the contact plate 14 and the frame 11.

[0025] In this embodiment, the sliding seat 6 and the frame 11 rotate synchronously through the rotating shaft 25, and then the harmonica shell 9 rotates along with the rotating shaft 25, and then the frame 11 is rotated to make the harmonica shell 9 rotate along with the frame 11, thereby facilitating multi-faceted and multi-angle adjustment of the harmonica shell 9, so as to facilitate the surface processing of the harmonica shell 9 and improve the practicability of the equipment.

[0026] like Figure 6 , Fig. 9 and Fig.10 As shown, in order to realize the rotation of the frame 11, the clamping and fixing device for harmonica processing provided in this embodiment also includes a transmission component, which is arranged in the transmission box 10, and is used to drive the frame 11 to rotate, and the transmission component includes a rotating sleeve 28, the rotating sleeve 28 is rotatably arranged in the transmission box 10, and a square shaft 26 is slidably installed in the rotating sleeve 28, the square shaft 26 slides axially along the rotating sleeve 28, and one end of the square shaft 26 passes through the rotating sleeve 28 and is installed with a first chuck 30, one end of the inner shaft 33 extends into the transmission box 10 and is installed with a second chuck 31 adapted to the first chuck 30, the square shaft 26 is pushed, so that the square shaft 26 slides inside the rotating sleeve 28, and the first chuck 30 is further pushed to move, so that the first chuck 30 is close to the second chuck 31, and the first chuck 31 and the second chuck 30 are engaged with each other, so that the rotational force of the inner shaft 33 is transmitted to the square shaft 26, and the rotating sleeve 28 is driven to rotate through the square shaft 26.

[0027] In addition, in order to realize the rotation of the frame 11, the present embodiment further includes a first bevel gear 29, the first bevel gear 29 is fixedly sleeved on the outside of the rotating sleeve 28, and the inner wall of the transmission box 10 is rotatably mounted with a connecting shaft, and a second bevel gear 32 meshing with the first bevel gear 29 is fixedly sleeved on the connecting shaft. Preferably, the transmission ratio between the first bevel gear 29 and the second bevel gear 32 is 1:1, and the other end of the connecting shaft is fixedly connected to the frame 11 on the same side. In the present embodiment, the first bevel gear 29 is driven to rotate by the rotating sleeve 28, and the first bevel gear 29 and the second bevel gear 32 are connected. The meshing between them causes the connecting shaft to rotate, thereby causing the frame 11 to rotate. The frame 11 and the contact plate 14 allow the harmonica shell 9 to rotate along with the frame 11, thereby realizing multi-angle adjustment of the harmonica shell 9, so as to facilitate the surface processing of the harmonica shell 9 and improve the practicality of the equipment. In addition, the first bevel gear 29 in this embodiment can be a worm, and the second bevel gear 32 can be a worm wheel. The meshing between the worm and the worm wheel can drive the connecting shaft to rotate, and the meshing between the worm wheel and the worm has a self-locking effect, thereby improving the stability of the connecting shaft during rotation.

[0028] like Figure 6 , Fig. 9 and Fig.10As shown, for the convenience of driving the square shaft 26 to achieve the engagement and disengagement of the first chuck 30 and the second chuck 31, a first electric telescopic cylinder 18 is fixed on the transmission case 10. A connecting plate 19 is fixed to the telescopic end of the first electric telescopic cylinder 18. The other end of the square shaft 26 penetrates through the transmission case 10 and is rotatably connected to the connecting plate 19. By the telescopic movement of the first electric telescopic cylinder 18, the connecting plate 19 moves, and the square shaft 26 is driven to move by the connecting plate 19, so as to achieve the engagement and disengagement of the first chuck 30 and the second chuck 31. During this process, since the square shaft 26 is rotatably connected to the connecting plate 19, interference on the connecting plate 19 caused by the rotation of the square shaft 26 can be avoided, improving the practicability of the equipment.

[0029] As Figure 4 、 Figure 7 and Figure 8 shown, for the convenience of installing the slide block 6, the slide block 6 provided in this embodiment has an inverted "U" - shaped structure, so as to facilitate the slide block 6 to be clamped on the inner support ring 4. And on one side inside the slide block 6, there are balls 27 that are in rolling connection with the inner wall of the inner support ring 4. Through the arrangement of the balls 27, the friction force during the movement of the slide block 6 is reduced, thereby improving the stability of the slide block 6 during movement.

[0030] As Figure 4 、 Figure 7 and Figure 8 shown, a friction ring 5 is provided on the outer side of the inner support ring 4. A second electric telescopic cylinder 23 is fixed on the outer side of the slide block 6. The telescopic end of the second electric telescopic cylinder 23 extends to the inside of the slide block 6 and is provided with a brake plate 24. The brake plate 24 is adapted to the friction ring 5. Through the sliding connection between the slide block 6 and the inner support ring 4, the slide block 6 rotates synchronously with the rotating shaft 25, thereby improving the stability of the rotation of the accordion - shaped outer shell 9 between the frame - shaped frame 11 and the abutting disc 14. By driving the second electric telescopic cylinder 23, the brake plate 24 abuts against the friction ring 5, thereby realizing the fixation of the slide block 6 to lock the rotation angle of the accordion - shaped outer shell 9. Preferably, the friction ring 5 is a rubber - made annular workpiece, and the outer surface of the friction ring 5 is provided with anti - slip lines to increase the friction force between the friction ring 5 and the brake plate 24, thereby improving the stability of the slide block 6 during fixation.

[0031] As Figure 1-Figure 4 shown, for the convenience of precisely controlling the rotation angle of the rotating shaft 25, a connecting rod 20 fixedly connected to the rotating shaft 25 is installed between the two slide blocks 6. Preferably, a limiting rod is provided between the connecting rod 20 and the transmission case 10 to improve the stability of the transmission case 10 after installation. In addition, a pointer 15 is fixed in the middle section of the connecting rod 20. The pointer 15 is perpendicular to the connecting rod 20. On the front surface of the outer support ring 3 inside the inner support ring 4, there is a protractor 12 adapted to the pointer 15. By driving the connecting rod 20 to rotate by the rotating shaft 25, the pointer 15 on the connecting rod 20 rotates synchronously with the rotating shaft 25. Through the mutual cooperation between the protractor 12 and the pointer 15, the precise measurement of the rotation angle of the rotating shaft 25 can be realized.

[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in order to facilitate fixing one end of the harmonica shell 9 inside the frame 11, a second fastening bolt 16 is rotatably installed on the frame 11, and the other end of the second fastening bolt 16 is rotatably connected to a pressure plate 17. A sliding notch is provided on one side of the pressure plate 17, and a sliding rail adapted to the sliding notch is provided on the inner side of the frame 11.

[0033] In this embodiment, the second fastening bolt 16 is rotated to drive the pressure plate 17 to move. Under the sliding connection between the slide rail and the sliding notch, the stability of the pressure plate 17 during movement can be improved. Through the cooperation between the pressure plate 17 and the frame 11, one end of the harmonica shell 9 can be fixed.

[0034] like Figure 9-11 As shown, in order to realize the driving of the inner shaft 33 and the rotating shaft 25, a motor 21 is fixed inside the support base 1, and a reduction gear box 34 is provided inside the support base 1. The output end of the motor 21 is fixed to the input end of the reduction gear box 34, and the output end of the reduction gear box 34 is connected to the rotating shaft 25 and the inner shaft 33 respectively, so that the rotating shaft 25 and the inner shaft 33 produce relative displacement when they rotate. Preferably, an input shaft 35 fixedly connected to the output end of the motor 21 is rotatably installed inside the reduction gear box 34, and a first gear is fixedly sleeved on the outer side of the input shaft 35 near one end. 36, and a second gear 37 is fixedly sleeved on the outer side of the input shaft 35 near the other end, one end of the rotating shaft 25 is extended to the interior of the reduction gear box 34 and a fourth gear 39 meshing with the second gear 37 is installed, one end of the inner shaft 33 passes through the rotating shaft 25 and is rotatably connected to the inner wall of the reduction gear box 34, and a third gear 38 is fixedly sleeved on the inner shaft 33. In addition, in order to realize the driving of the inner shaft 33, a linkage gear 40 is also rotatably installed inside the reduction gear box 34, and the linkage gear 40 is meshed with the first gear 36 and the third gear 38.

[0035] In this embodiment, the motor 21 works to drive the input shaft 35 to rotate, and the first gear 36 and the second gear 37 are rotated synchronously by the input shaft 35. Under the meshing action between the second gear 37 and the fourth gear 39, the fourth gear 39 drives the rotating shaft 25 to rotate. Preferably, the transmission ratio between the second gear 37 and the fourth gear 39 is 3:1. In addition, under the meshing action between the first gear 36 and the linkage gear 40, the linkage gear 40 is rotated, and the inner shaft 33 is rotated through the meshing between the linkage gear 40 and the third gear 38. Preferably, the third gear 38 is meshed with the first gear 36 and the linkage gear 40. The transmission ratio among the first gear 36, the linkage gear 40 and the third gear 38 is 6:3:1, so that the inner shaft 33 and the rotating shaft 25 rotate at different speeds, that is, when the rotating shaft 25 rotates one circle, the inner shaft 33 rotates 20 degrees. Since the transmission ratio between the first bevel gear 29 and the second bevel gear 32 is 1:1, the rotation angle of the frame 11 is 1 / 18 of the rotation angle of the rotating shaft 25, which is beneficial to the accurate measurement and control of the rotation angle of the frame 11, improves the precision of the equipment, and facilitates the user to perform more refined processing on the harmonica shell 9.

[0036] In order to fix the outer support ring 3 , fixing rods 13 fixedly connected to the inner wall of the outer support ring 3 are fixed at equal intervals on the outside of the connecting sleeve 22 to prevent the outer support ring 3 from rotating.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the bracket 7 provided in this embodiment is an "L"-shaped structure, which is convenient for the installation of the first fastening bolt 8, thereby facilitating the limiting of the other end of the harmonica housing 9, and the bracket 7 is welded to the slide 6, and a supporting inclined plate is provided between the bracket 7 and the outer wall of the slide 6. The triangular structure formed by the supporting inclined plate, the bracket 7 and the slide 6 is arranged to improve the stability of the bracket 7 after installation.

[0038] like Figure 1 As shown, the support seat 1 is a component made of stainless steel, and is provided with an equipment cavity 2 adapted to the outer support ring 3 and the inner support ring 4. The plane where the inner wall of the equipment cavity 2 is located forms a right-angle structure inside the space, so that the support seat 1 can be placed in multiple surfaces, thereby improving the practicability of the equipment.

[0039] When in use (working), fix the support seat 1 and place one end of the harmonica shell 9 inside the frame 11, rotate the second fastening bolt 16, and push the pressure plate 17 toward the harmonica shell 9 through the second fastening bolt 16, so that one end of the harmonica shell 9 is clamped between the pressure plate 17 and the frame 11, move the first fastening bolt 8, and push the contact plate 14 toward the other end of the harmonica shell 9 through the first fastening bolt 8, so as to achieve the fixation of the other end of the harmonica shell 9, and then achieve the fixation of harmonica shells 9 of different specifications, through the setting of the double slide seat 6 and the double bracket 7, and then through the cooperation of the two frame frames 11, the double harmonica shells 9 can be synchronously fixed, and the number of clamping is increased, so as to improve the subsequent processing efficiency of the harmonica shell 9.

[0040] Start the motor 21, and the input shaft 35 is rotated by the motor 21, and the first gear 36 and the second gear 37 are rotated synchronously by the input shaft 35. Under the meshing action between the second gear 37 and the fourth gear 39, the fourth gear 39 drives the rotating shaft 25 to rotate. In addition, under the meshing action between the first gear 36 and the linkage gear 40, the linkage gear 40 is rotated, and the inner shaft 33 is rotated through the meshing between the linkage gear 40 and the third gear 38, so that the inner shaft 33 and the rotating shaft 25 rotate at different speeds.

[0041] The connecting rod 20 and the transmission box 10 are driven to rotate by the rotating shaft 25, and the slide 6 and the frame 11 are further rotated synchronously, and then the harmonica shell 9 is rotated along with the rotating shaft 25, so as to prevent the harmonica shell 9 from being deformed due to excessive torque. At this time, the pointer 15 rotates synchronously with the connecting rod 20. With the cooperation of the protractor 12, the rotation angle of the pointer 15 can be effectively measured, so that the user can measure the rotation angle of the rotating shaft 25, which is further beneficial to control the rotation angle of the harmonica shell 9 along with the rotating shaft 25. When the harmonica shell 9 rotates to the required angle, the second electric telescopic cylinder 23 is started, and the brake plate 24 is moved by the second electric telescopic cylinder 23, and the brake plate 24 is further fitted with the friction ring 5, so as to realize the locking of the slide 6 and prevent the slide 6 from continuing to slide. The rotation angle of the harmonica shell 9 can be further locked, so that the user can perform processing operations on the harmonica shell 9.

[0042] The first electric telescopic cylinder 18 is started, and the connecting plate 19 is driven by the first electric telescopic cylinder 18 to move, so that the square shaft 26 slides inside the rotating sleeve 28, which is further conducive to controlling the clutch between the first chuck 30 and the second chuck 31. It should be noted that due to the speed difference between the inner shaft 33 and the rotating shaft 25, during the engagement process of the first chuck 30 and the second chuck 31, the power of the inner shaft 33 will be transmitted to the square shaft 26 through the first chuck 30 and the second chuck 31, so that the square shaft 26 rotates, and the rotating sleeve 28 is rotated by the square shaft 26. 8 rotates, thereby making the first bevel gear 29 rotate along with the rotating sleeve 28, and through the meshing between the first bevel gear 29 and the second bevel gear 32, the second bevel gear 32 drives the frame 11 to rotate, so that the harmonica shell 9 rotates synchronously with the frame 11, so that the harmonica shell 9 rotates around its axial direction, which is beneficial to the multi-faceted and multi-angle processing of the harmonica shell 9. When the first chuck 30 and the second chuck 31 are separated, the power of the inner shaft 33 will not be transmitted to the square shaft 26, thereby preventing the frame 11 from rotating.

[0043] In addition, the transmission ratio between the second gear 37 and the fourth gear 39 is 3:1, the transmission ratio between the first gear 36, the linkage gear 40 and the third gear 38 is 6:3:1, and the transmission ratio between the first bevel gear 29 and the second bevel gear 32 is 1:1, so that the rotation angle of the frame 11 is 1 / 18 of the rotation angle of the rotating shaft 25, that is, the rotation angle of the frame 11 is 1 / 18 of the rotation angle of the pointer 15, which is beneficial to the accurate measurement and control of the rotation angle of the frame 11, improves the precision of the equipment, and is beneficial to the user to perform more refined processing of the harmonica shell 9.
