[0022] Figure 1 It is a bidirectional clamping device for pipe cutting. Figure 2 yes Figure 1 A local decomposition diagram of Figure 3 This is a schematic diagram of the meshing of the tooth plate and the auxiliary gear. Figure 4 yes Figure 3 The top view comprises two transmission plates 4, two auxiliary gears 5, and two clamping blocks 8; each transmission plate 4 is provided with two tooth plates 41, wherein the two tooth plates 41 of one transmission plate 4 are meshed and connected with the two tooth plates 41 of the other transmission plate 4 respectively through the auxiliary gear 5; the two clamping blocks 8 are respectively connected to the two transmission plates 4; the clamping blocks 8 are provided with square clamping openings for clamping pipe fittings.

[0024] The utility model utilizes two transmission plates, two clamping blocks and two oil cylinders to clamp pipe fittings on both sides. Compared with the solution in the prior art in which one side is fixed to support the pipe fitting and the other side is moved to clamp the pipe fitting, the utility model clamps the pipe fitting from both sides, which is more stable and will not vibrate or shake during cutting, with good clamping effect and good cutting effect.

[0025] The transmission plate 4 is equipped with a guide block 11 and also includes an auxiliary plate 6. The auxiliary plate 6 is fixed to the base plate 1. The auxiliary plate 6 is provided with two axial holes 61 for installing the auxiliary gear 5. The auxiliary plate 6 is provided with a guide groove 62 that matches the guide block 11 for guiding. The auxiliary plate 6 of the utility model is fixedly connected to the base plate 1, so that the auxiliary plate 6 serves as a base plate, and the guide block 11 matches the guide groove 82. When the two oil cylinders 2 are actuated, the transmission plate 4 is driven to move relative to or in the opposite direction. At this time, the guide block 11 moves along the guide groove 62, ensuring that the movement is linear and preventing deviation when clamping the pipe. The utility model installs the shaft of the auxiliary gear 5 on the auxiliary plate 6 and the base plate 1. When the two oil cylinders drive the two transmission plates to move, under the meshing action of the auxiliary gears, the two pairs of tooth plates can mesh with each other for transmission, and under the action of the teeth, the transmission plates will not separate from each other, ensuring the linearity of the movement and achieving a good clamping effect.

[0026] Auxiliary blocks 7 are installed at both ends of the auxiliary plate 6 , which are connected to the guide blocks 11 . The clamping blocks 8 are connected to the auxiliary blocks 7 . The auxiliary blocks 7 are also installed with baffles 9 .
