A quick-positioning clamping assembly 2 is arranged at the top of the main body 1 of the four-axis quick-clamping pneumatic fixture, a chip absorption assembly 3 is installed on the side of the main body 1 of the four-axis quick-clamping pneumatic fixture, and a width positioning assembly 4 is arranged on the side of the quick-positioning clamping assembly 2.

[0028] Please refer to Figure 2 、 Figure 3As shown in the figure, a four-axis quick-clamping pneumatic fixture, the quick positioning and clamping assembly 2, includes a pneumatic fixture main body 201. A moving plate 202 is provided at the bottom of the pneumatic fixture main body 201, and a moving chute 203 is snap-connected to the bottom of the moving plate 202. A fixing screw 204 is provided on the side of the moving plate 202, and a screw chute 205 is snap-connected to the outer wall of the fixing screw 204. A fixing nut 206 is threadedly connected to the bottom of the fixing screw 204. A scale indicator 207 is fixedly connected to the outer wall of the moving plate 202, and a scale body 208 is provided on the side of the scale indicator 207. According to the length of the four-axis, adjust the position of the moving plate 202. Loosen the fixing screw 204, horizontally move the moving plate 202. The moving plate 202 slides inside the moving chute 203, the fixing screw 204 slides inside the screw chute 205, and the scale indicator 207 slides on the side of the scale body 208. Stop at a suitable length position, and then tighten the fixing screw 204 to fix the position of the moving plate 202, which is convenient for adjusting the device according to the size of the product, making it suitable for products of different sizes and improving the flexibility of the device.

[0029] Please refer to Figure 4 、 Figure 5 As shown in the figure, a four-axis quick-clamping pneumatic fixture, the debris absorption assembly 3, includes a vacuum cleaner 301. A debris dust collection box 302 is snap-connected inside the vacuum cleaner 301, and a positioning slot 303 is fixedly connected to the side of the debris dust collection box 302. A fixing slot 304 is provided at the bottom of the positioning slot 303. A plug housing 305 is provided at the top of the positioning slot 303, and a fixed plug 306 is fixedly inserted inside the plug housing 305 through a sliding structure. Debris will be generated during the use of the device. The vacuum cleaner 301 absorbs the debris and stores it centrally in the debris dust collection box 302. When the device is used up, slide the fixed plug 306 upward to make it leave the fixing slot 304 and the positioning slot 303. When the fixed plug 306 reaches the top of the plug housing 305, rotate the fixed plug 306 to fix it, and then remove the debris dust collection box 302 to centrally process the debris inside the debris dust collection box 302, which is convenient for absorbing the debris generated during the processing, ensuring the cleanliness inside the device and avoiding blockage.

[0030] Please refer to Figure 6As shown, a four-axis quick-clamping pneumatic jig, a width positioning assembly 4, includes a positioning plate 401. An adjusting rotating shaft 402 is provided on the side of the positioning plate 401, and a rotating knob 403 is provided on the other side of the adjusting rotating shaft 402. The outer wall of the rotating knob 403 is threadedly connected to a fixing plate 404. According to the width of the four-axis, rotate the rotating knob 403. Since the rotating knob 403 is threadedly connected to the fixing plate 404, the positioning plate 401 moves horizontally. At the same time, the rotating knob 403 rotates around the adjusting rotating shaft 402. Stop rotating the rotating knob 403 at an appropriate width, which is convenient for adjusting the position of the positioning plate 401 according to the width of the product so that it can fit products of different gears.

[0031] Working principle: First, according to the length of the four-axis, adjust the position of the moving plate 202. Loosen the fixing screw 204 and move the moving plate 202 horizontally. The moving plate 202 slides inside the moving chute 203, and the fixing screw 204 slides inside the screw chute 205. The scale indicator 207 slides on the side of the scale body 208. Stop at an appropriate length position, and then tighten the fixing screw 204 to fix the position of the moving plate 202. Then, according to the width of the four-axis, rotate the rotating knob 403. Since the rotating knob 403 is threadedly connected to the fixing plate 404, the positioning plate 401 moves horizontally. At the same time, the rotating knob 403 rotates around the adjusting rotating shaft 402. Stop rotating the rotating knob 403 at an appropriate width. Next, debris will be generated during the use of the device. The vacuum cleaner 301 absorbs the debris and stores it centrally in the debris dust collection box 302. When the device is used up, slide the fixed bolt 306 upward so that it leaves the fixed card slot 304 and the positioning card slot 303. When the fixed bolt 306 reaches the top of the bolt housing 305, rotate the fixed bolt 306 to fix it. Then remove the debris dust collection box 302 to centrally process the debris inside the debris dust collection box 302.
