Description
Technical field
The utility model relates to cold tube rolling production equipment, particularly a kind of auxiliary steel pipe muscle clamping device.
Background technology
Cold tube rolling precision is high, surface smoothness is good, be widely used on accurate machine construction, hydraulic test, cold tube rolling itself has belonged to a finished product, only slightly need do processing and just can become a product use, improve stock utilization, reduce processing cost, need to use a very long steel pipe muscle when manufacturing cold tube rolling as plug, steel pipe socket is carried out fine finishining outside, thus intermediate demand use multiple bracing or strutting arrangement and clamping device could by stretching for the production of processing steel pipe for the steel pipe muscle of several meters of growing up.
Utility model content
For solving the problem, the purpose of this utility model is to provide the auxiliary steel pipe muscle clamping device that a kind of structure is simple, easy to use, adjustable, have clamping function.
For achieving the above object, the technical solution of the utility model:
A kind of auxiliary steel pipe muscle clamping device, comprise gear-box, cylinder, bracing frame, flange end cap, first scroll chuck, second scroll chuck, described gear-box is square inner hollow out, the both sides that spline and connecting axle run through gear-box are connected on gear-box by bearing, spline and connecting axle are equipped with gear and intermesh, be fixedly connected with base plate by bolt bottom gear-box, gear-box top is provided with cylinder, the piston rod of cylinder and bracing frame upper end chain connection, bracing frame is taken the shape of the letter U and middle to be flexibly connected with flange end cap by adjusting bolt, by connecting rod, bracing frame and gear-box are connected to each other bottom bracing frame, flange end cap is flexibly connected by steel ball with the first scroll chuck, first scroll chuck clamps with the second scroll chuck and is connected, connecting axle is through flange end cap, first scroll chuck and the second scroll chuck, connecting axle and the second scroll chuck interference fits.
As preferably, be hollow with flange end cap, the first scroll chuck, the second same center of scroll chuck in the middle of described connecting axle.
As preferably, described connecting axle is penetrated by the card base of the second scroll chuck.
As preferably, described flange end cap can rotate relatively with the first scroll chuck.
Beneficial conditions of the present utility model is: structure is simple, easy to use, adjustable, have clamping function.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model first scroll chuck.
Fig. 3 is the structural representation of the utility model connecting axle inside.
Detailed description of the invention
As Fig. 1, 2, shown in 3, a kind of auxiliary steel pipe muscle clamping device, comprise gear-box 1, cylinder 2, bracing frame 3, flange end cap 4, first scroll chuck 5, second scroll chuck 6, described gear-box 1 is square inner hollow out, the both sides that spline 7 and connecting axle 8 run through gear-box 1 are connected on gear-box 1 by bearing, spline 7 with connecting axle 8 are equipped with gear and intermesh, be fixedly connected with base plate 9 by bolt bottom gear-box 1, gear-box 1 top is provided with cylinder 2, piston rod 10 and the bracing frame 3 upper end chain connection of cylinder 2, bracing frame 3 is taken the shape of the letter U and middle to be flexibly connected with flange end cap 4 by adjusting bolt 11, by connecting rod 12, bracing frame 3 and gear-box 1 are connected to each other bottom bracing frame 3, flange end cap 4 is flexibly connected by steel ball 13 with the first scroll chuck 5, first scroll chuck 5 clamps with the second scroll chuck 6 and is connected, connecting axle 8 is through flange end cap 4, first scroll chuck 5 and the second scroll chuck 6, connecting axle 8 and the second scroll chuck 6 interference fits.Be hollow with the same center of flange end cap 4, first scroll chuck 5, second scroll chuck 6 in the middle of described connecting axle 8.Described connecting axle 8 is penetrated by the card base 14 of the second scroll chuck 6.Described flange end cap 4 can rotate relatively with the first scroll chuck 5.Steel pipe muscle of the present utility model exports from the input of connecting axle 8 left end from right-hand member, be clamped under the effect of the second scroll chuck 6, by the elasticity of the adjustable whole steel pipe muscle of the cylinder 2 on gear-box 1, when cylinder 2 shrinks steel pipe muscle just pine, when cylinder 2 extends, steel pipe muscle has just been tightened up, connecting axle 8 is driven to rotate by gears meshing when spline 7 rotates, connecting axle 8 drives the second scroll chuck 6 to rotate, steel pipe muscle and steel pipe is finally driven together to rotate, can make steel pipe to add man-hour stressed more even cold rolling like this, improve the quality of products.
