Detailed description of the invention

Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.

As Figure 1-3, a kind of pipe clamping device, it comprises pipe clamp mould 2, loads the mold box 1 of pipe clamp mould 2 and adjustment assembly;

Described pipe clamp mould 2 comprises the mold 22 and bed die 21 that cooperatively interact, described mold 22 is relative arc with bed die 21, and the radian of described bed die 21 is greater than the radian of described mold 22, described mold 22 comprises the first patrix 222 and the second patrix 223 connected by adjustment spring 221; One side of described mold 22 is provided with scale 23, and described mold box 1 sidewall is provided with the observation window 11 corresponding with described scale 23 position, and observation window 11 is made up of the glass of transparent material;

Described mold 22 is made up of the first patrix 222 and the second patrix 223 being arc shape, the bottom of the first patrix 222 is provided with positive stop lug boss, described second patrix 223 is positioned at described positive stop lug boss side, and the radian of described first patrix 222 is greater than described second patrix 223 radian, the end face outside copline of the second patrix 223 outer surface after the first patrix 222 is connected by adjustment spring 221 with the second patrix 223 and the positive stop lug boss of the first patrix 222.

Described adjustment assembly comprises cam set, bracing frame 43 and the handle 42 be connected with cam set, described cam set is connected to form in its center of gravity by two identical cams 44, the center of gravity place of described two cams 44 is connected by a gravity axis 43, this gravity axis 43 connects an adjusting lever 45, described adjusting lever 45 connects a bracing frame 43, the bottom of this bracing frame 43 and the form fit of described first patrix 222, be hollow in the middle part of bracing frame 43, the adjusting lever 45 in described adjusting lever 45 vacancy through described hollow space and in this is arranged with spring 46, this spring 46 is connected on the inner face of support frame as described above 43 hollow space.

Be provided with a cam case 3 above described mold box 1, described cam set is placed in its inside, and the sidewall of this cam case 3 has chute 41, the shape of described chute 41 is identical with the centre-of-gravity path of cam 44, and described gravity axis 43 is slidably installed on chute 41.

On described cam case 3, one end has groove 32, and this groove 32 is V-type, and described handle 42 is through this groove 32.

The handle bar 45 of described handle 42 comprises the first handle bar part and the second handle bar part, described first handle bar part is connected with cam set, and this first handle bar part is circular arc, one end of described second handle bar part is connected with the first handle bar part, the other end of the second handle bar part is provided with a projection, and described second handle bar part is rectangle, is provided with a draw-in groove below the groove 32 of described cam case 3, the protruding snap-fit engagement of this draw-in groove and described second handle bar part.

The operation principle of the present embodiment:

First, be placed on bed die 21 need the pipe of cutting, then by handle 42 rotating cam 44, cam 44 is made to drive adjusting lever 45 to rotate, then mold 22 is forced to move down, abut to pipe, then continue to move downward, a reverse power can be provided by pipe after second patrix 223 touches pipe, second patrix 223 just starts compression adjustment spring 221, until adjustment spring 221 reaches the limit of position, now mold 22 has clamped pipe, thus can start the operation of carrying out cutting.

And adjust spring 221 set up exactly in order to adapt to the pipe tube wall of multiple diameter;

The radian that the radian of mold 22 is less than bed die 21 becomes a supporting bracket to just make bed die 21, and be unlikely to when mold 22 clamps pipe, pipe skids off from bed die 21;

By the gravity motion of cam 44, just can there is upper and lower displacement in the mold 22 be connected by bracing frame 43 and adjusting lever 45 with it, and the chute 41 on cam case 3 is exactly the movement locus that ensure that cam 44;

And this device adopts cam to be because the operation of cam is more laborsaving and save operating space as the important composition of adjustment assembly.

The profile design of handle 42 adds the mobile space of handle 42 to greatest extent, and the circular arc tangent line of the first handle part of handle 42 and the axis of second handle part are in obtuse angle;

Setting up of scale 23 is exactly that handled easily personnel judge the length that pipe is cut in time.

Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
