Detailed implementation manners

[0016] Please refer to Figures 1-6 , a clamping and fixing tool for aluminum alloy processing, comprising a base 1, a moving mechanism 2 and a horizontal clamping mechanism 3 are arranged on the top of the base 1, a limiting mechanism 4 is arranged on the surface of the horizontal clamping mechanism 3, and a vertical clamping mechanism 5 is arranged on the surface of the horizontal clamping mechanism 3; the moving mechanism 2 is used to adjust the position of the horizontal clamping mechanism 3 to adapt to workpieces of different sizes, the horizontal clamping mechanism 3 can initially fix the workpiece, the vertical clamping mechanism 5 can further clamp the workpiece in the vertical direction to ensure that the workpiece does not displace during the processing, and the limiting mechanism 4 provides positioning for the internal components of the horizontal clamping mechanism 3 during the clamping process to prevent the workpiece from accidentally moving during the clamping or processing.

[0017] The horizontal clamping mechanism 3 includes two mounting boxes 301. The bottom of one mounting box 301 is fixedly connected to the top of the base 1. A bidirectional lead screw 302 is rotatably connected to the inner wall of the mounting box 301. Two double-link sliding sleeves 303 are threadedly connected to the surface of the bidirectional lead screw 302. A driving handwheel 304 is arranged on one side of the mounting box 301. One end of the driving handwheel 304 penetrates through the mounting box 301 and is fixedly connected to one end of the bidirectional lead screw 302. A guide rod 305 is fixed to the inner wall of the mounting box 301. The double-link sliding sleeve 303 is slidably connected to the surface of the guide rod 305. A chute 306 is formed on the surface of the mounting box 301. A mounting plate 307 is fixed to the top of the double-link sliding sleeve 303. The mounting plate 307 is slidably connected to the surface of the chute 306. A T-shaped clamping plate 308 slidably penetrates through the surface of the mounting plate 307; By rotating the bidirectional lead screw 302 through the driving handwheel 304, the double-link sliding sleeve 303 slides along the surfaces of the guide rod 305 and the bidirectional lead screw 302, realizing the synchronous approaching or separating movement of the T-shaped clamping plate 308 in the chute 306. This design is not only simple in structure and convenient to operate, but also can quickly adjust the clamping position, improve the processing efficiency. The setting of the guide rod 305 further ensures the smoothness of the sliding, avoiding deviation during the clamping process. The design that the T-shaped clamping plate 308 can slide inside the mounting plate 307 realizes the quick pre-positioning of the T-shaped clamping plate 308, reduces the number of turns of the threaded rod adjustment, and can adapt to more irregular workpieces, further improving the adaptability of the device.

[0018] Furthermore, the moving mechanism 2 includes two pedestal bearings 201 and two guide rails 205. The pedestal bearings 201 are fixedly connected to the top of the base 1. A screw rod 202 is fixedly connected to the inner wall of the pedestal bearing 201. A movable seat 203 is threadedly connected to the surface of the screw rod 202. The top of the movable seat 203 is fixedly connected to the bottom of one mounting box 301. The guide rail 205 is fixedly connected to the top of the base 1. A slider 206 is slidably connected to the surface of the guide rail 205. The top of the slider 206 is fixedly connected to the bottom of one mounting box 301. One end of the screw rod 202 is fixed with an adjusting handwheel 204; When it is necessary to adjust the position of the horizontal clamping mechanism 3, by rotating the adjusting handwheel 204, the screw rod 202 rotates in the pedestal bearing 201, driving the movable seat 203 to move along the guide rail 205. By sliding the slider 206 on the guide rail 205, the smoothness of the moving process is ensured. This design enables the horizontal clamping mechanism 3 to adapt to aluminum alloy workpieces of different sizes, further improving the flexibility and versatility of the clamping tool.

[0019] Further, the limiting mechanism 4 includes a mounting bracket 401 which is fixed to the top of the mounting plate 307. A limiting rod 402 slidably penetrates through the surface of the mounting bracket 401, and the limiting rod 402 also slidably penetrates through the mounting plate 307. A plurality of limiting holes 309 for the limiting rod 402 to be inserted into are formed in the top of the T-shaped clamping plate 308. A sliding plate 403 is fixed to the surface of the limiting rod 402. A spring 404 is fixed to the top of the sliding plate 403, and the top of the spring 404 is fixedly connected to the inner top wall of the mounting bracket 401. A pulling plate 405 is fixed to the top of the limiting rod 402. When adjusting the position of the T-shaped clamping plate 308 inside the mounting plate 307, the sliding plate 403 is pulled upward through the pulling plate 405, and the spring 404 is compressed and stores energy. At this time, the limiting rod 402 is disengaged from the limiting hole 309 and the surface of the mounting plate 307, so that the T-shaped clamping plate 308 can slide without being blocked. After adjusting to the required position, the limiting rod 402 is moved downward, so that the bottom end of the limiting rod 402 enters the inside of the limiting hole 309, thereby realizing the limitation of the T-shaped clamping plate 308 and preventing the T-shaped clamping plate 308 from moving during the clamping process.

[0020] Further, the vertical clamping mechanism 5 includes a combined housing 501 which is fixed to the surface of the mounting box 301. A T-shaped groove is formed in the surface of the combined housing 501. An I-shaped plate 507 is slidably connected to the inner wall of the T-shaped groove. A vertical plate 502 is fixed to the top of the I-shaped plate 507. A sliding sleeve 503 is slidably connected to the surface of the vertical plate 502. An extension plate 504 is fixed to the surface of the sliding sleeve 503. An adjusting screw rod 505 is threadedly connected to the surface of the extension plate 504. The bottom of the adjusting screw rod 505 is rotatably connected to a top clamping plate 506. Two guide rods 511 are fixed to the top of the top clamping plate 506, and the guide rods 511 slidably penetrate through the extension plate 504. A limiting structure for limiting the height of the sliding sleeve 503 is arranged on the surface of the sliding sleeve 503. When it is necessary to vertically clamp the workpiece, the height position of the sliding sleeve 503 can be adjusted according to the overall height of the workpiece first, and then the sliding sleeve 503 is limited by the limiting structure. After that, the adjusting screw rod 505 is rotated to drive the top clamping plate 506 to move downward, so as to drive the top clamping plate 506 to apply a vertical clamping force. During this period, the guide rods 511 slide in the extension plate 504 to ensure the smooth movement of the top clamping plate 506. This design makes the vertical clamping operation more flexible, can adapt to workpieces of different heights, and when there is no need to clamp in the vertical direction, the I-shaped plate 507 can be directly taken out from the inside of the combined housing 501, thereby realizing the removal of the vertical plate 502 and the combined housing 501, so that more types of workpieces can be placed on the surface of the mounting box 301.

[0021] Furthermore, the surface limiting structure of the sliding sleeve 503 includes a pin rod 509. The pin rod 509 slidably penetrates through the sliding sleeve 503. A plurality of pin holes 508 for fitting the pin rod 509 are formed on the surface of the vertical plate 502. A deformable limiting wire 510 slidably penetrates through the surface of the pin rod 509. Through the cooperation of the pin rod 509 and the pin hole 508, the pin rod 509 is passed through the sliding sleeve 503 and the pin hole 508, which can limit the height of the sliding sleeve 503, thereby controlling the position of the top extension plate 504 and ensuring that the extension plate 504 does not move up and down during the clamping process. And sliding the limiting wire 510 through the surface of the pin rod 509 can limit the pin rod 509 to prevent the pin rod 509 from detaching from the surface of the sliding sleeve 503.

[0022] Furthermore, the bottom of the limiting rod 402 is designed with a semi-circular structure, and the top edge of the limiting hole 309 is designed with a chamfer structure. During the limiting operation, the bottom of the semi-circular limiting rod 402 cooperates with the top edge of the chamfered limiting hole 309, enabling the limiting rod 402 to be inserted into the limiting hole 309 more smoothly, thereby fixing the position of the T-shaped clamping plate 308. This design reduces the operating resistance and improves the service life and reliability of the limiting mechanism 4.

[0023] Furthermore, guiding grooves 406 are formed on both sides of the surface of the mounting bracket 401, and the sliding plate 403 is slidably connected to the surface of the guiding grooves 406. The design of the guiding grooves 406 can guide the movement of the sliding plate 403, making its movement more stable, avoiding the sliding plate 403 from shifting during the movement process, and improving the working reliability of the limiting mechanism 4.

[0024] Furthermore, rubber anti-slip pads 6 are fixed on the surfaces of the T-shaped clamping plate 308 and the top clamping plate 506, and anti-slip patterns are provided on the surfaces of the rubber anti-slip pads 6. The rubber anti-slip pads 6 can increase the friction between the clamping plate and the workpiece, prevent the workpiece from sliding during the clamping process, and at the same time play a buffering role, protecting the surface of the workpiece from being scratched and improving the surface quality of the workpiece.

[0025] Working principle: First, by rotating the adjustment handwheel 204, the screw rod 202 drives the movable seat 203 to move along the guide rail 205, thereby adjusting the position of the mounting box 301 on one side to adapt to workpieces of different sizes. Then, the workpiece is placed on the surfaces of the two mounting boxes 301. By rotating the two driving handwheels 304, the bidirectional lead screw 302 drives the double-link sliding sleeve 303 to move towards each other along the guide rod 305, thereby driving the T-shaped clamping plate 308 to achieve clamping in the horizontal direction. The limiting mechanism 4 fixes the position of the T-shaped clamping plate 308 by inserting the limiting rod 402 into the limiting hole 309, ensuring the stability of clamping and also enabling the position of the T-shaped clamping plate 308 to be adjusted and limited according to requirements to adapt to workpieces of more shapes. Then, by rotating the adjustment lead screw 505, the adjustment lead screw 505 drives the top clamping plate 506 to move downward, so that the top clamping plate 506 applies a clamping force in the vertical direction. Through the coordinated action of the above-mentioned parts, this clamping and fixing tool can ensure the stability and precision of the aluminum alloy workpiece during the processing, while improving the operation convenience and the tool versatility.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
