A kind of pipe clamping device
Technical field
The utility model relates to a kind of pipe clamping device.
Background technology
Usually need in the process of manufacture of tubing to use clamping device location.Common locate mode is that the movable block of the band V-shaped groove that employing two is arranged on slide rail carrys out clamping and positioning, and V-shaped groove is arranged on the opposite face of movable block.The shortcoming of this clamping device is the tubing be only applicable within the scope of certain size, and pipe diameter exceedes this scope, and just need the sliding shoe more renewed could continue processing, troublesome poeration, affects production efficiency.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of clamping device being applicable to the tubing of various sizes.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pipe clamping device, comprise mount pad, mount pad center is provided with the circle material hole passed through for tubing, mount pad is evenly equipped with the clamp jaw of at least three clamping tube material and tube walls around circular Liao Kong center circumference, clamp jaw tail end is hinged on mount pad, be interconnected by connecting rod between adjacent two clamp jaws, interlinking lever end is hinged on the outside of clamp jaw and mount pad tie point, mount pad is provided with at least one and drives each clamp jaw inwardly to rotate to clamp the driving cylinder of material, the piston rod end of cylinder and one of them clamp is driven to be hinged, the tie point of piston rod end and clamp jaw is in the outside of interlinking lever end and clamp tie point.
As the preferred scheme of one, the clamping area of described clamp jaw is provided with rubber slab.
As the preferred scheme of one, the joint ball bearing that described connecting rod is comprised shaft and is connected by screw thread with shaft, joint ball bearing hinge connection is on described clamp jaw.
As the preferred scheme of one, described mount pad is provided with two and drives cylinder, and drives cylinder to be that intermediate symmetry is arranged around the circle material hole circle heart.
As the preferred scheme of one, described clamp is being provided with reinforcing ring away from the one side of mount pad, one end of the jointed shaft of described connection clamp jaw and mount pad is rotatably connected on reinforcing ring.
The beneficial effects of the utility model are: drive cylinder to promote the structure that multiple clamp jaw inwardly rotates to clamp tubing because this clamping device adopts, automatically can complete the clamping to various sizes tubing, and structure is simple, easy to operate, good clamping effect.
Because the clamping area of clamp jaw is provided with rubber slab, can better tubing be clamped and not damage tube surfaces.
Due to the joint ball bearing that connecting rod is comprised shaft and is connected by screw thread with shaft, joint ball bearing hinge connection, on described clamp jaw, is convenient to install.
Drive cylinder because mount pad is provided with two, and drive cylinder to be that intermediate symmetry is arranged around the circle material hole circle heart, the chucking power of each clamp jaw can be made comparatively even.
Due to clamp being provided with reinforcing ring away from the one side of mount pad, one end of the jointed shaft of described connection clamp jaw and mount pad is being rotatably connected on reinforcing ring, makes the installation of clamp jaw more firm, not fragile.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1-2, a kind of pipe clamping device, comprises mount pad 1, and mount pad 1 center is provided with the circle material hole passed through for tubing 7, mount pad 1 is evenly equipped with the clamp jaw 2 of at least three clamping tubing 7 tube walls around circular Liao Kong center circumference, the clamping area of clamp jaw 2 is provided with rubber slab 3.Clamp jaw 2 tail end is hinged on mount pad 1, be interconnected by connecting rod 4 between adjacent two clamp jaws 2, connecting rod 4 end is hinged on the outside of clamp jaw 2 and mount pad 1 tie point, the joint ball bearing 42 that connecting rod 4 is comprised shaft 41 and is connected by screw thread with shaft 41, joint ball bearing 42 is hinged on described clamp jaw 2.Mount pad 1 is provided with two and drives each clamp jaw 2 inwardly to rotate with the driving cylinder 5 clamping material, and drive cylinder 5 to be that intermediate symmetry is arranged around the circle material hole circle heart, drive the piston rod end of cylinder 5 and one of them clamp to be hinged, the tie point of piston rod end and clamp jaw 2 is in the outside of connecting rod 4 end and clamp tie point.
Clamp is provided with reinforcing ring 6 in the one side away from mount pad 1, connects clamp jaw 2 and be rotatably connected on reinforcing ring 6 with one end of the jointed shaft of mount pad 1.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
