[Specific implementation method]

[0011] The anti-slip clamping and pulling mechanism of the front-pulling laser tube cutting machine described in the utility model is further described in detail below through specific embodiments.

[0012] like Figure 1As shown, a non-slip clamping and pulling mechanism of a front-pulling laser tube cutting machine includes a hollow box body 1, a left rotating shaft 2 and a right rotating shaft 3 are arranged at the front end of the box body 1, and the left rotating shaft 2 and the right rotating shaft 3 are arranged at both sides of the front end of the box body 1, respectively. The lower part of the left rotating shaft 2 extends out of the box body 1, and the left clamping arm 4 is connected to the extended part thereof, and the lower part of the right rotating shaft 3 extends out of the box body 1, and the right clamping arm 5 is connected to the extended part thereof. The left clamping arm 4 and the right clamping arm 5 are arranged symmetrically to each other, and can clamp the pipe fitting when closed. The left rotating shaft 2 located in the box body 1 is connected to the left clamping driving arm 6, and the right rotating shaft 3 located in the box body 1 is connected to the right clamping driving arm 7. The left clamping driving arm 6 and the right clamping driving arm 7 are arranged inwardly, and the inner side surfaces of the left clamping driving arm 6 and the right clamping driving arm 7 are both inwardly curved arc surfaces. A movable driving block 8 is arranged between the left clamping driving arm 6 and the right clamping driving arm 7, and a guide groove 9 is arranged at the bottom of the box body 1, and the driving block 8 moves along the guide groove 9. Rollers 10 are arranged on both sides of the driving block 8, respectively, and the rollers 10 are respectively fitted with the inner side surfaces of the left clamping driving arm 6 and the right clamping driving arm 7. A main cylinder 11 for moving the driving block 8 is arranged on the outside of the box body 1, and a left auxiliary cylinder 12 and a right auxiliary cylinder 13 are also arranged on both sides of the outside of the box body 1. A left pressure wheel 14 is arranged at the front end of the movable rod of the left auxiliary cylinder 12, and the left pressure wheel 14 is fitted with the outer side surface of the left clamping driving arm 6. A right pressure wheel 15 is arranged at the front end of the movable rod of the right auxiliary cylinder 13, and the right pressure wheel 15 is fitted with the outer side surface of the right clamping driving arm 7.

[0013] The working principle of the utility model is as follows: when working, the movable rod of the main cylinder 11 contracts, driving the driving block 8 to move backward along the guide groove 9, and the rollers 10 on both sides of the driving block 8 make the left clamping driving arm 6 and the right clamping driving arm 7 open outwards, and synchronously, the movable rods of the left auxiliary cylinder 12 and the right auxiliary cylinder 13 also contract, and make the left pressure wheel 14 and the right pressure wheel 15 always keep in contact with the outer side of the left clamping arm 4 and the right clamping arm 5. When the left clamping driving arm 6 and the right clamping driving arm 7 open outwards, the left rotating shaft 2 and the right rotating shaft 3 are driven to rotate synchronously, thereby driving the left clamping arm 4 and the right clamping arm 5 to close inwards, thereby forming a clamping of the pipe fitting. It adopts two left and right auxiliary cylinders to provide auxiliary pressure to the clamping driving arm, so that the clamping arm always keeps a clamping state during clamping to prevent the pipe fitting from loosening.
