Abstract

The utility model relates to a clamping device of a cutting machine, comprising a base plate. The base plate is provided with a hole, and the same radii around the center of the hole are hinged with a plurality of clamping claws with same shapes. The end part of each clamping claw is provided with a clamping block, each two clamping claws are connected by a connecting rod, and the length of the connecting rods is same. The radians between adjacent clamping claw hinging points are equal, and one of the clamping claws is connected with a cylinder on the base plate. The utility model has the advantages of compact machine structure, small size, large clamping range and adjustable clamping force, and the clamping claws can automatically center.

Description

The cutting machine clamping device

Technical field

The utility model relates to a kind of tubing production equipment, especially relates to a kind of improvement of pipe cutting equipment structure.

Background technology

Now with the real wall plastic tube of heavy caliber, last procedure on machining production line is to require according to the rules to cut.The cutting machine clamping device of prior art, adopting up and down mostly, Hough (semicircle) clamps, such clamp mechanism not only needs to be equipped with different size tubing anchor clamps according to the production line specification series, and when cutting different size tubing, to frequently change, this has not only increased expense, and troublesome poeration, and the Hough arc size is a fixed value in addition, can crush outer wall when tube outer diameter is bigger than normal, the meeting clamping is not tight when less than normal.

Summary of the invention

The utility model main purpose is: develop a kind of cutting machine clamping device, to adapt to the clamping problem of different-diameter tubing.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cutting machine clamping device, it is characterized in that: have seat board, on seat board, have the hole, around the center in hole, on same radius, be hinged with the identical gripper jaw of a plurality of shapes, link to each other with connecting rod two or two between the described gripper jaw, one of them gripper jaw links to each other with cylinder on being connected seat board.

The technical solution of the utility model can also be further perfect:

As preferably, the radian between the adjacent gripper jaw pin joint equates.

As preferably, the length of connecting rod of adjacent gripper jaw equates.

As preferably, there is fixture block the end of gripper jaw.

The beneficial effects of the utility model are: compact integral structure, and volume is little, the self-centering of gripper jaw energy, clamping range is big, and clamping force is adjustable.

Description of drawings

Accompanying drawing 1 is a kind of structural front view of the present utility model;

Accompanying drawing 2 is side diagrammatic sketch of Fig. 1.

The specific embodiment

Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

Embodiment:

Cutting machine clamping device as shown in Figure 1 and Figure 2, has seat board 1, on seat board, have the hole, around the center in hole, on same radius, be hinged with six gripper jaws 3 that shape is identical by pin joint 31, fixture block 32 is housed on the gripper jaw, distance between the gripper jaw 3 equates (distance radian equal or that be called on the same circumference equates between each hinge), connecting rod 4 two two with equal length between the gripper jaw 3 links to each other, one of them gripper jaw 3 links to each other with cylinder 2, and cylinder is hinged with the cylinder block 21 that is installed on the seat board.

After cylinder fed compressed air, piston rod will drive six gripper jaws 3 like this, rotated around bearing pin separately, make six fixture blocks tightly clamp the tubing 5 that is in six pawl centers, realize clamping function.

The cutting machine clamping device of present embodiment:

Model is SLQJ250 (400);

Adapt to caliber φ 110-φ 250 (φ 200-φ 400).
