Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] An adjustable punching device includes a workbench 1, a three-axis frame 3 is fixedly installed on the rear side of the workbench 1, and the three-axis frame 3 is operated to realize up and down, left and right, front and back movement so that the drill contacts the surface of the guitar to perform punching work, and a clamping mechanism 2 is arranged on the top of the workbench 1 for stably fixing and clamping the guitar, and the clamping mechanism 2 includes:

[0027] The mounting assembly 21 is arranged on the top of the workbench 1, and includes a mounting box 211 fixedly mounted on the top of the workbench 1, and a right slide groove 212 and a left slide groove 213 are provided on the top of the mounting box 211, and the right slide groove 212 and the left slide groove 213 are rectangular in shape;

[0028] The kinetic energy assembly 22 is arranged on the top of the workbench 1, and includes a right slider 229 slidably mounted inside the right slide groove 212, and a 226 slidably mounted inside the left slide groove 213;

[0029] The adapter assembly 23 is arranged at the top of the mounting assembly 21, and includes a mounting block 231 fixedly mounted on the top of the right slider 229 and the left slider 226, and a plurality of slide posts 232 are installed in the mounting block 231, and a clamping plate 233 is fixedly installed on the inner end of the slide post 232, and a clamping head 234 is fixedly installed on the inner side of the clamping plate 233, and a limit block 236 is fixedly installed on the outer end of the slide post 232, and a return spring 235 is movably sleeved on the surface of the slide post 232. The left slider 226 The adapter component 23 set on the top is mirror-symmetrical with the adapter component 23 set on the top of the right slider 229. The two adapter components 23 move toward each other to clamp the guitar in the middle. At the same time, when multiple clamping heads 234 contact the edge of the guitar, the slide column 232 slides to make the clamping plate 233 squeeze the return spring 235. Each clamping head 234 has a different contact point with the edge of the guitar, and the sliding distance of the slide column 232 is different, so as to adapt to the edge curvature of the guitar for clamping, thereby achieving stable clamping of the guitar.

[0030] In this embodiment, the kinetic energy component 22 also includes a driving motor 221 fixedly installed at the bottom of the workbench 1 tabletop. The driving motor 221 is a three-phase asynchronous motor, which is electrically connected to an external power supply and realizes the opening and closing operation through a personnel-controlled control panel. The output end of the driving motor 221 is rotatably installed with a motor shaft 222. The top end of the motor shaft 222 passes through the workbench 1 tabletop and a turntable 223 is fixedly installed inside. The left side of the top of the turntable 223 is movably connected to a left connecting rod 224 through a connecting pin, and the left end of the left connecting rod 224 is movably inserted and installed with a left connecting column 225. The right side of the top of the turntable 223 is movably connected to a right connecting rod 227 through a connecting pin, and the left end of the right connecting rod 227 is movably inserted and installed with a right connecting column 228. The top of the connecting column 225 is fixedly connected to the bottom of the left slider 226, and the top of the right connecting column 228 is fixedly connected to the bottom of the right slider 229. The driving motor 221 drives the motor shaft 222 to rotate, and the motor shaft 222 drives the turntable 223 to rotate. When the turntable 223 rotates, the left connecting column 225, the left slider 226 and the right connecting column 228, and the right slider 229 are pulled toward each other through the left connecting rod 224 and the right connecting rod 227, thereby driving the two adapter components 23 to move toward each other. When the turntable 223 rotates clockwise, the connection point between the left connecting rod 224 and the turntable 223 moves upward clockwise to drive the left connecting rod 224 to move, and the connection point between the right connecting rod 227 and the turntable 223 moves downward clockwise to drive the right connecting rod 227 to move.

[0031] In this embodiment, the return spring 235 is installed between the mounting block 231 and the clamping plate 233. After the guitar processing is completed, the two adapter components 23 move in opposite directions. At this time, the return spring 235 pushes the clamping plate 233 through its own elasticity, thereby resetting the slide post 232, the clamping plate 233, and the clamping head 234, and the return of the slide post 232 is limited by the limit block 236.

[0032] In this embodiment, the clamping head 234 is semicircular in shape and made of rubber. The clamping head 234 is fixedly installed on one side of each clamping plate 233. The clamping head 234 contacts the edge of the guitar, thereby increasing the friction between the guitar and the clamping force. At the same time, the clamping head 234 can play a buffering role, reducing the impact and wear on the guitar, thereby protecting the guitar.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] During operation, the guitar is first placed on the top of the installation box 211, and then the driving motor 221 is operated to drive the motor shaft 222 to rotate, and at the same time, the motor shaft 222 drives the turntable 223 to rotate. When the turntable 223 rotates, the left connecting column 225, the left slider 226, the right connecting column 228, and the right slider 229 are pulled toward each other through the left connecting rod 224 and the right connecting rod 227, thereby driving the two adapter components 23 to move toward each other, and then the two adapter components 23 move toward each other to clamp the guitar in the middle, and at the same time, when multiple clamping heads 234 contact the edge of the guitar, the slide column 232 slides, so that the clamping plate 233 squeezes the return spring 235, and each clamping head 234 has a different contact point with the edge of the guitar, and the sliding distance of the slide column 232 is different, which is adapted to the edge curvature of the guitar for clamping, and then the three-axis frame 3 moves up and down, left and right, and front and back to make the drill contact with the surface of the guitar for drilling.
