Description
Technical field
The utility model relates to a kind of machining tool clamp, is a kind of manually centre frame clamping device specifically.
Background technology
The processing of endoporus, end face and screw thread to part in machining, can not hold out against with tailstock, therefore needs to carry out supplemental support clamping part with centre frame.Centering center rest high cost, and traditional manual centre frame clamping device because of its complex structure, clamping range is little and interchangeability is poor thereby effect is undesirable.How designing a kind of manual centre frame clamp mechanism simple in structure, easy to operate and with low cost and that have good interchangeability is that those skilled in the art wants the technical problem solving always.
Utility model summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, it is a kind of simple in structure, easy to operate that the utility model provides, and has the manual centre frame clamping device of good economy and interchangeability.
Technical scheme: a kind of manually centre frame clamping device, comprise centre frame body, also comprise handwheel, shaft end ring, end cap, rotating shaft, be with female sliding sleeve, clamping and positioning piece, flat key and holding screw; Described handwheel connects as one by shaft end ring and rotating shaft, and is also embedded with flat key between described shaft end ring and handwheel; On described rotating shaft and clamping and positioning piece, be provided with the external screw thread suitable with the internal thread of sliding sleeve, on described centre frame body, be also provided with endoporus, described sliding sleeve is arranged in the endoporus of centre frame body, described rotating shaft is inserted into one end of sliding sleeve by screw thread, and sliding sleeve can move up and down under the effect of rotating shaft in the endoporus of centre frame body, described clamping and positioning piece is arranged on the other end of sliding sleeve and is connected as a whole with sliding sleeve by screw thread; Aperture place countershaft that described end cap is arranged on the endoporus of centre frame body carry out axial location; On described sliding sleeve, be also provided with kidney slot, described holding screw is inserted in the kidney slot of sliding sleeve through centre frame body; In the endoporus of described centre frame body, be also provided with forced filling oil cup.
Wherein, on described clamping and positioning piece, be also provided with extension bar.Due to limited space, the stroke limiting system moving up and down of sliding sleeve, increases the clamping range of manual centre frame by increasing extension bar, thus the requirement of different clamping diameter of parts.
Wherein, the screw thread on described rotating shaft, sliding sleeve and clamping and positioning piece is left hand thread.
Wherein, the material of described clamping and positioning piece is brass.In order not affect the precision of the treatment of surfaces of components, the clamping and positioning piece of choice for use brass material.
Wherein, described clamping device is provided with three covers altogether, being arranged on centre frame body of even angle.In order to ensure machining accuracy, three cover clamping devices are set and are used in conjunction with.
Beneficial effect: compared with prior art, the utlity model has following advantage: the utility model is as a kind of servicing unit of machine components processing, reduce the Design and manufacture cost of lathe, and this apparatus structure is simple, good rigidly, mounting or dismounting are easy to adjust, use reliable, there is good economy and interchangeability, relate in particular to the processing of many kinds part of user, meet the machining demand of user to numerically controlled lathe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
