Specific implementation manner
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a clamping and placing device for violin making, including a base 1. On both sides of the top of the base 1, support arms 2 are provided through rotary interfaces. At the top of the support arm 2, a telescopic rod 3 is fixed by screws. The telescopic rod 3 is an existing hydraulic cylinder. The output end of the telescopic rod 3 is welded and fixed with a fixing block 4. The outer end of the fixing block 4 is connected with a clamping module 5. A multi-point clamping mechanism 6 is provided on the clamping module 5. The multi-point clamping mechanism 6 is composed of multiple groups of independently adjustable rotating shafts 61 and clamping heads 62. And a stud 64 is fixed on the outer side of the rotating shaft 61. An adjusting screw ring 63 screwed on the outside of the stud 64 is provided at the inner end of the clamping head 62. And an angle adjustment mechanism 7 for rotating the position of the rotating shaft 61 is provided at the top of the clamping module 5. The support arm 2 of this structure can freely rotate around the rotary interface on the top of the base 1 to adapt to the clamping requirements in different directions. When the telescopic rod 3 is driven, the length can be adjusted and the fixing block 4 can be driven to push and use the clamping module 5 to clamp the violin parts. And the multi-point clamping mechanism 6 can finely adjust the position and the applied pressure of each clamping head 62 by rotating the adjusting screw ring 63 to ensure that during the whole clamping process, the pressure is evenly distributed, avoiding deformation or damage of the violin parts caused by excessive local force. At the same time, the angle adjustment mechanism 7 can adjust the position of the rotating shaft 61 at the top of the clamping module 5, so that the clamping head 62 can flexibly adapt to the irregular shape of the violin parts, improving the accuracy and stability of clamping. To sum up, through the coordinated work of each component, this device not only improves the stability and accuracy of clamping the violin parts, but also greatly enhances the flexibility of operation, effectively solves the problems existing in the traditional fixture, and greatly improves the working efficiency of violin making. The angle adjustment mechanism 7 includes a lever 71, a strip-shaped support block 72, a locking pin 73 and a strip-shaped through hole 74. The lever 71 is welded and fixed inside the top of the rotating shaft 61. The strip-shaped through hole 74 is opened at the upper end of the clamping module 5 and corresponds to the position of the lever 71. The strip-shaped support block 72 is arranged below the strip-shaped through hole 74 and is welded and fixed at the connection with the clamping module 5. The locking pin 73 is inserted and connected to the outer end of the lever 71. The outer end of the lever 71 extends out of the outside of the clamping module 5 through the strip-shaped through hole 74. And a number of lock holes matching the structure of the locking pin 73 are evenly provided on the strip-shaped support block 72. In this structure, when the angle of the clamping head 62 needs to be adjusted, the operator can manually pull the locking pin 73 to make it break out of the lock hole on the strip-shaped support block 72. Then, the lever 71 is moved through the strip-shaped through hole 74 to drive the rotating shaft 61 and the clamping head 62 thereon to rotate to the required angular position. After the adjustment is completed, the locking pin 73 is released to make it re-insert into the lock hole at the corresponding position on the strip-shaped support block 72 to realize the fixation of the rotating shaft 61. This not only enables the clamping head 62 to be flexibly adjusted to the best clamping angle to adapt to different shapes of the violin parts, improving the accuracy and stability of clamping, but also is simple and fast to operate, effectively improving the working efficiency of violin making. A pressure column 8 is welded and fixed on the back side of the clamping module 5.Moreover, the inside of the fixing block 4 is provided with a pressing hole that matches the structure of the pressing column 8, and a flexible pad 9 is provided on the inner wall of the inner end of the pressing hole of the fixing block 4. When the clamping module 5 clamps, this structure will drive the pressing column 8 to slide to a certain extent in the pressing hole inside the fixing block 4. When the pressing column 8 slides, it will squeeze the flexible pad 9, and the flexible pad 9 can play a buffering role to reduce the potential damage to the components caused by hard collisions. There are three clamping heads 62 in total on the outside of the clamping module 5, and the clamping heads 62 are spherical structures made of soft material. When clamping the violin components, these three clamping heads 62 can contact and wrap the components from different angles. The spherical design of the soft material of the clamping heads 62 can not only increase the contact area with the surface of the violin components, ensure uniform distribution of pressure, prevent damage to the components caused by excessive local pressure, but also slightly deform according to the specific shape of the components, better fit the irregular surface, and improve the stability and reliability of clamping. The bottom of the base 1 is provided with an anti-slip gasket, and the anti-slip gasket at the bottom of the base 1 is fixed to the periphery of the bottom of the base 1 through an adhesive. When the base 1 is placed on the workbench, the anti-slip gasket at the bottom can be in close contact with the tabletop, and the high friction coefficient of its surface can effectively increase the friction between the base 1 and the tabletop, prevent the device from sliding or shifting during the clamping operation of the violin components, and ensure the stability of the entire device.
[0019] Working principle: When using the clamping and placing device for violin making, first place the base 1 on a stable workbench, and then adjust the direction of the support arm 2 by rotating the rotating interface of the support arm 2 on the top of the base 1 according to the specific position and shape of the violin components to make it reach the optimal support angle. Then, adjust the telescopic rod 3 to drive and adjust the length to push the fixing block 4 to an appropriate position. Subsequently, according to the actual size and shape of the components, rotate the adjusting ring 63 outside the stud 64 to finely adjust the position and the applied pressure of each clamping head 62 in the multi-point clamping mechanism 6 to ensure uniform distribution of the clamping force. If it is necessary to adjust the angle of the clamping head 62, the locking pin 73 can be pulled to disengage the lever 71 from the locking hole on the strip-shaped support block 72, and then move the lever 71 along the strip-shaped through-hole 74 to drive the rotating shaft 61 to rotate to the required angle. Finally, release the locking pin 73 and insert it back into the locking hole on the strip-shaped support block 72 to complete the fixation. During the clamping process, the pressing column 8 will slide in the pressing hole inside the fixing block 4 and squeeze the flexible pad 9 on the inner wall of the inner end of the pressing hole to play a buffering role. Finally, the three spherical clamping heads 62 made of soft material contact and wrap the violin components from different angles, ensuring the stability and reliability of clamping, and thus completing a series of operations.
[0020] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
