Description
Technical field
The utility model belongs to Machining Technology field, is specifically related to the tubing clamp mechanism of the rotating pipe cutting machine of a kind of cutter.
Background technology
The rotating pipe cutting machine of cutter is a kind of special equipment that is used for specially cutting tubular workpiece, in cutting process, first need to clamp by clamp mechanism one end of materials in the tube, then pipe cutting machine circumgyration incision workpiece, but the pressure bearing in cutting process for balance tubing in the prior art, it is wider that clamp mechanism clamping section arranges, and occupied mass efficient space, the tubing tailing length that can be used for cutting is shortened greatly, thereby cause unnecessary waste.
Utility model content
The purpose of this utility model is the above-mentioned defect for the rotating pipe cutting machine clamp mechanism of existing cutter, the tubing clamp mechanism of the rotating pipe cutting machine of a kind of cutter is disclosed, particularly one not only clamps firm and can make tubing to be cut fully cut, and avoids iron filings to stick in the clamp mechanism on cut pipe fitting simultaneously.
The purpose of this utility model can realize by following technical proposal:
The tubing clamp mechanism of the rotating pipe cutting machine of a kind of cutter, be arranged in the head of pipe cutting machine, it is characterized in that, it comprise tubular pull bar, be positioned at the clamping element of pull bar front end and be positioned at the horizontal drive mechanism that pull bar end can drive pull bar to seesaw, described clamping element comprises annular collet, collet and tubing concentric to be cut, can control collet internal diameter varies when described pull bar seesaws.
When cutting, first tubing to be cut one end is sent to put in annular collet, now collet does not have binding force to tubing, after driving pull bar to travel forward to make the internal diameter of collet to diminish to clamp tubing one end by horizontal drive mechanism, supplies with cutting tool cutting.
In the tubing clamp mechanism of the above-mentioned rotating pipe cutting machine of a kind of cutter, the front opening size of described pull bar is greater than collet size and internal diameter band internal taper and collet external taper and coincide.Pull bar is in collet approach process, because being greater than collet size and internal diameter band internal taper and collet external taper, the front opening size of pull bar coincide, the internal diameter of collet is towards the thrust that is also subject to pull bar near pull bar direction, generation strain endoporus diminishes gradually, thereby can better clamp one end of tubing to be cut.
In the tubing clamp mechanism of the above-mentioned rotating pipe cutting machine of a kind of cutter, on described pull bar, be arranged with can be free-moving with respect to pull bar drag link sleeve, the outer end of drag link sleeve is provided with collet and spells cap, and the periphery of above-mentioned collet is provided with train of dress, between train of dress and drag link sleeve, is connected by securing member.Like this pull bar just can with collet relative motion, in the time that collet need to clamp tubing, pull bar travels forward, need to unclamp tubing time, pull bar moves backward.
In the tubing clamp mechanism of the above-mentioned rotating pipe cutting machine of a kind of cutter, described collet is spelled between cap and drag link sleeve and is together by a threaded connection.
In the tubing clamp mechanism of the above-mentioned rotating pipe cutting machine of a kind of cutter, described horizontal drive mechanism comprises the driving oil cylinder that is fixedly installed on internal body, the piston rod of oil cylinder is set on pull bar, piston rod is provided with piston, and described piston is along pull rod shaft to cylinder cavity being divided into former and later two chambers.
In above-mentioned former and later two chambers, be respectively equipped with oil pipe, when needing oil cylinder just to drain the oil in chamber corresponding to this direction in the time that certain direction drives pull bar, and oil-filled in the chamber of another one direction, as needs drive forwards pull bar, in the front chamber of oil cylinder, drain the oil, oil-filled in the rear chamber of oil cylinder.
Compared with prior art, the utility model is simple in structure, can not only firm clamping tubing, and space tubing being taken due to collet is less, the tubing tailing length that can be used for cutting is increased greatly, thereby saved production cost.

Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the tubing clamp mechanism of the rotating pipe cutting machine of a kind of cutter, be arranged in the head 1 of pipe cutting machine, it comprise tubular pull bar 2, be positioned at the clamping element 3 of pull bar 2 front ends and be positioned at the horizontal drive mechanism 4 that pull bar 2 ends can drive pull bar 2 to seesaw, clamping element 3 comprises annular collet 5, collet 5 and tubing concentric to be cut, can control collet 5 internal diameter varies when pull bar 2 seesaws.
The outer end of pull bar 2 is arranged with drag link sleeve 6, both energy relative motions, the outer end of drag link sleeve 6 is provided with collet and spells cap 7, collet is spelled between cap 7 and drag link sleeve 6 and is together by a threaded connection, the periphery of collet 5 is provided with train of dress, between train of dress and drag link sleeve 6, be connected by securing member, in the present embodiment, securing member is locking nut 8.
Horizontal drive mechanism 4 comprises the driving oil cylinder 9 that is fixedly installed on head 1 inside, the piston rod 10 of oil cylinder 9 is fixed on pull bar 2 by nut 13, piston rod 10 is provided with piston 11, piston 11 is axially divided into former and later two chambers 12 by oil cylinder 9 inner chambers along pull bar 2, hydraulic oil enters respectively the front and back oil pocket of oil cylinder (9), promoting piston rod (10) seesaws, thereby drive pull bar (2) to seesaw, the oblique cone of pull bar (2) front end compresses, loosen collet (5), make collet (5) that strain occur, clamp, unclamp tubing.
When work, tubing to be cut one end is sent in annular collet 5, pull bar 2 is in collet 5 approach process, because the front opening size of pull bar 2 is greater than collet 5 sizes and internal diameter towards dwindling gradually away from collet 5 directions, thereby the internal diameter of collet 5 clamps tubing one end towards also diminishing gradually near pull bar 2 directions, supplies cutting tool cutting after clamping.
