Problems solved by technology
[0004] However, since the rubber plate of the above-mentioned automatic variable-diameter chipless cutting machine has a fixed radian size, when the diameter of the pipe is greatly different from the optimal diameter, if stable clamping is required, a larger clamping force is required, which is easy crushed pipe

Embodiment Construction
[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0027] A pipe cutting machine clamping device, such as figure 1 As shown, it includes a mounting plate 4, a cylinder 1, an active claw arm 2 and a plurality of driven claw arms 6 on the mounting plate, the active claw arm 2 is connected to the cylinder 1, the active claw arm 2 and each driven claw arm 6 It is evenly arranged around the pipe, and the adjacent claw arms are connected by the linkage rod 5, the ends of all claw arms are provided with rubber blocks 7, and the ends of all claw arms are provided with a mounting groove, such as figure 2 and image 3 As shown, the m...

The invention relates to a pipe cutting machine clamping device which comprises an installation plate, an air cylinder, a driving claw arm and a plurality of driven claw arms, the air cylinder, the driving claw arm and the driven claw arms are arranged on the installation plate, the driving claw arm is connected with the air cylinder, the driving claw arm and the driven claw arms are evenly arranged around a pipe, the adjacent claw arms are connected through linkage rods, and rubber blocks are arranged at the tail ends of all the claw arms. A mounting groove is formed in the tail end of each claw arm, a threaded column is arranged in the mounting groove, a threaded hole matched with the threaded column is formed in the rubber block, the rubber block is detachably connected with the claw arms through the threaded hole and the threaded column, and soft cushions for holding are arranged on all the claw arms. Compared with the prior art, through the design of the threaded column and the threaded hole, the rubber block is stable and detachable, so that the rubber block can be used for clamping a pipe with a larger diameter, the friction coefficient is increased, and the pipe can be prevented from being damaged due to too large pressure.
Description
technical field [0001] The invention relates to a pipe clamping device, in particular to a clamping device for a pipe cutting machine. Background technique [0002] The traditional clamping device of the pipe cutting machine uses a special clamp, and the clamp is pushed by the upper and lower cylinders to clamp the pipe. This structure has obvious disadvantages, that is, for pipes of different specifications, workers need to manually replace the clamps, and the clamping size is also different. Affected by fixture size. [0003] In the prior art, in order to solve the above problems, some clamping devices with variable sizes are provided. For example, Chinese patent CN102452097A discloses an automatic variable diameter chip-free cutting machine, which includes a frame and a a supporting mechanism, a clamping mechanism and a rotating mechanism, the clamping mechanism comprises a clamping base plate with a clamping through hole, and a clamping cylinder, a front rotating arm an...
