[0022] The adjustment mechanism 4 includes a motor 401 fixedly mounted on the front side wall of the frame 2, a gear 402 located inside the frame 2 is fixedly mounted on the output shaft of the motor 401, a tooth plate 1 403 is meshed with the right side of the gear 402, a laser print head 404 is arranged at the bottom of the tooth plate 1 403, a tooth plate 2 405 is meshed with the left side of the gear 402, and a tool 406 is movably mounted at the bottom of the tooth plate 2 405.

[0023] Slide grooves are provided on the left and right inner walls of the box body 3, and a slide rod slidably connected to the slide groove is fixedly installed on the opposite side of the tooth plate 1 403 and the tooth plate 2 405, and a spring 2 is fixedly installed between the tooth plate 1 403 and the tooth plate 2 405 and the inner top wall of the box body 3. By setting the slide groove and the slide rod, the stability of the tooth plate 1 403 and the tooth plate 2 405 during lifting and lowering is improved, and by setting the spring 2, the lifting and lowering of the tooth plate 1 403 and the tooth plate 2 405 are buffered, and through the movement of the tooth plate 1 403 and the tooth plate 2 405 in opposite directions, one of the laser print head 404 or the tool 406 can be lifted, so that material addition and subtraction can be carried out separately.

[0024] A lifting mechanism is provided on the top of the box body 3, and the lifting mechanism includes an electric telescopic rod 601 fixedly installed between the frame 2 and the box body 3, guide columns 602 are fixedly installed at both ends of the top of the box body 3, and the top of the frame 2 is provided with sliding openings adapted to the two guide columns 602.

[0025] Guide wheels are fixedly installed on the left and right side walls of the box body 3, and guide rails compatible with the guide wheels are opened on the left and right inner walls of the frame 2. Under the action of the guide wheels and the guide rails, the stability of the box body 3 when moving up and down is improved. When it is necessary to increase or decrease material at the same time, the tooth plate 1 403 and the tooth plate 2 405 are located at the same height, and the box body 3 is driven to move downward by the electric telescopic rod 601, and the box body 3 drives the tooth plate 1 403 and the tooth plate 2 405 to move downward, so that the increase or decrease of material can be carried out synchronously.

[0026] A disassembly mechanism 5 is provided between the tool 406 and the tooth plate 405, and the disassembly mechanism 5 includes cavities 501 opened at both ends inside the tooth plate 405, and cross bars 502 are fixedly installed inside the two cavities 501, and springs 503 are sleeved on the outer surfaces of the two cross bars 502, and sliders 504 are slidably installed on the outer surfaces of the two cross bars 502, and clamping rods 505 are fixedly installed at the bottoms of the two sliders 504, and clamping grooves 506 are opened at both ends of the top of the tool 406.

[0027] Pull rods are fixedly installed on the front side walls of the two sliders 504, and openings located on the outer surfaces of the two pull rods are opened on the front side wall of the tooth plate 405. By pulling the pull rods, the pull rods drive the sliders 504 to move relative to each other through the openings, so that the two clamping rods 505 are withdrawn from the inside of the two clamping grooves 506, and the tool 406 is removed for replacement.

[0028] When implementing, follow these steps:

[0029] 1) When it is necessary to perform material addition and subtraction at the same time, the electric telescopic rod 601 is extended to drive the box body 3 to move downward stably, and the box body 3 drives the tool 406 and the laser print head 404 to move downward to perform material addition and subtraction work;

[0030] 2) When the tool 406 or the laser print head 404 needs to be used separately, the motor 401 drives the gear 402 to rotate, and the gear 402 drives the tooth plate 1 403 and the tooth plate 2 405 to move in opposite directions. The tooth plate 1 403 and the tooth plate 2 405 drive the tool 406 and the laser print head 404 to be located at different heights, so as to facilitate separate operation;

[0031] 3) When the cutter 406 is worn and needs to be replaced, the two pull rods are pulled in opposite directions, and the pull rods drive the slider 504 to move toward the direction close to the spring 1 503. Under the contraction of the spring 1 503, the slider 504 drives the clamping rod 505 to exit the clamping groove 506. At this time, the worn cutter 406 can be removed and replaced with a new cutter 406;

[0032] 4) Finally, the two pull rods are loosened, and the two clamping rods 505 are clamped into the two clamping grooves 506 through the expansion of the spring 1 503 .

[0033] In summary, the additive and subtractive processing machine tool with a tool head quick-change device, by setting a lifting mechanism, can drive the laser print head 404 and the tool 406 to descend under the drive of the electric telescopic rod 601, so that additive and subtractive processing can be carried out simultaneously, thereby improving processing efficiency, and by setting an adjustment mechanism 4, the laser print head 404 and the tool 406 can be moved in opposite directions under the rotation of the gear 402, so that additive or subtractive operation can be selected according to processing requirements, and additive and subtractive processing can be carried out simultaneously or separately, which is flexible to use and has wide adaptability.

[0034] Furthermore, since the cutter 406 may be worn out due to long-term use during the processing, the cutter 406 can be quickly replaced by providing a disassembly mechanism 5, thereby greatly improving the processing efficiency and product quality.
