1, telescopic head can only by adjusting screw(rod) realize away from by paracentral function.The part that this structure centre frame can't fixed profile is taper seat.Because with this centre frame fixedly during taper seat contacting between the contact bearing of centre frame and part be the line contact, thereby circular groove appears in too little excessive part and the centre frame contact site of causing of contact site pressure that cause of contact-making surface.
2, this centre frame can't fixed profile the part that is arc surface.Because with this centre frame fixedly during taper seat contacting between the contact bearing of centre frame and part be the line contact, thereby facet appears in too little excessive part and the centre frame contact site of causing of contact site pressure that cause of contact-making surface.
The utility model content
The purpose of this utility model causes piece surface the problem of circular groove to occur while being the fixing non-face of cylinder of centre frame in order to solve traditional structure part, and a kind of centre frame with rotatable contact head is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of centre frame with rotatable contact head of the present utility model, comprise connecting ring, the identical clamp mechanism of the three above structures of cover;
Connecting ring is the cirque structure that two bulk-breakings form, and an end of two bulk-breakings of connecting ring is connected through the hinge, and the other end of two bulk-breakings of connecting ring is locked by snap close;
Every cover clamps mechanism and includes chuck body, screw rod, locking nut, fixed head, slide block, bearing pin, contact, roller;
The tubular construction that chuck body is both ends open, in the cylindrical shell of chuck body, shape is rectangular configuration,
The interior shape of the profile of slide block and chuck body is complementary, and the front end of slide block is processed with the journal stirrup with the horizontal direction axis hole, and the rear end of slide block is processed with the dovetail groove of along continuous straight runs;
The contact rear end is processed with the journal stirrup with the horizontal direction axis hole be complementary with slip front, and contact front end axle connects roller, and the connecting axle of contact and roller is perpendicular to the axis hole on the slip front journal stirrup;
Have screwed hole on fixed head;
The internal thread of the external screw thread on screw rod and fixed head upper screwed hole is complementary, and screw front end is processed with the positioning table be complementary with slide block rear end dovetail groove;
Screw rod inserts in the dovetail groove of slide block rear end by the positioning table of front end, makes screw rod and slide block in the vertical direction location; The journal stirrup of slip front is connected by bearing pin with the journal stirrup of contact rear end; Chuck body is enclosed within outside slide block, and slide block can be slided in chuck body, spiro rod rear end be threaded successively fixed head and locking nut, and fixed head and chuck body rear end are fixed;
The chuck body of all clamp mechanism is fixed on connecting ring homonymy and uniform, makes the center of circle of the slide block movement direction of all clamp mechanism towards connecting ring.
The course of work
During clamping work pieces, at first workpiece to be clamped is inserted in the connecting ring of centre frame, rotary screw, the relative fixed head of screw rod is moved down, and then the slide block of promotion and screw rod vertical direction location moves forward, the clamping of realization to workpiece to be clamped, and move in the other direction by screwing the anti-limited slip block of locking nut; Because the contact of slip front is connected by bearing pin with it, contact can be freely adjusted and the workpiece to be clamped contact angle, thereby realize that the surface of roller Plane of rotation and workpiece to be clamped fully fits.
Beneficial effect
The utility model is simple in structure, easy for installation, but clamp the clamp contact of angle by free adjustment, realized that the Plane of rotation of contact front end roller and the surface of workpiece to be clamped fully fit, solve traditional centre frame and can cause surface of the work the technical barrier of circular groove to occur when clamping non-face of cylinder workpiece, there is important practical value.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model centre frame;
Wherein, 1-connecting ring; The 2-chuck body; The 3-screw rod; The 4-locking nut; The 5-fixed head; The 6-slide block; The 7-bearing pin; The 8-contact; The 9-roller.
