Description
Technical field
The present invention relates to the two-way main shaft chuck on a kind of double-end vehicle, particularly the structure of the two-way main shaft chuck of a kind of wedge pushing-type double-end vehicle, belongs to jig Design manufacturing technology field.
Background technology
The fixture of existing double-end vehicle holding workpiece has: two-direction, main axle clamp seat, double end processing air-or liquid-operated chuck etc., this kind of fixture can only clamp bar and the pipe part that diameter is not more than 100mm usually, and the profile of bar and pipe part must be regular cylindrical.But in machining, need double end to process the part to be processed being greater than 100mm or irregular profile but often to run into, such as: a kind of compared with the external diameter of long pipe fittings being welded with many dentate leaf parts along its length, this part not only diameter is large, and surface configuration is complicated, thus cannot clamped by existing double-end vehicle fixture, the working axiality at its two ends then cannot ensure.Therefore, the fixture of existing double-end vehicle holding workpiece has its limitation.
Summary of the invention
The object of the present invention is to provide the two-way main shaft chuck of a kind of wedge pushing-type double-end vehicle, make up that existing double-end vehicle holder diameter of work is little, the drawback of bad adaptability.
To achieve these goals, Bian of the present invention gets following technical scheme and implements: the two-way main shaft chuck of a kind of wedge pushing-type double-end vehicle, comprise main shaft, ring washer, wedge throw-out collar, spacer ring, jaw and spring, spindle hole is provided with in main shaft, outside axle journal is bearing in main shaft of head case by two bearings, and two ends are stretched out outside main shaft of head case, it is characterized in that:
The wall portion of described main shaft external part to be respectively equipped with in same radial section and to be distributed in three radial direction through hole of circumference, and through hole is square hole;
On the external diameter of described spacer ring matched in clearance inside main shaft external part wall portion radial direction through hole, and by inner axial location;
The fastening main shaft end face of described ring washer, and form by ring washer one end and the rectangular ring groove between spacer ring outer end and main shaft external diameter;
Be equipped with a jaw in three radial direction through hole of described main shaft external part wall portion respectively and also and between main shaft form moving sets, jaw front end is stretched in spindle hole, and rear end is inserted in rectangular ring groove;
Annular boss is provided with in the middle part of described wedge throw-out collar endoporus, boss face is provided with three sections and has identical profile and the even lozenges being distributed in circumference, the point of 120 ° that three sections of lozenges are often separated by is equal to the distance of wedge throw-out collar axis, boss side annular distance coordinates with spacer ring crest clearance, opposite side annular distance coordinates with ring washer crest clearance, boss both sides and endless groove both sides matched in clearance;
Described spring is placed between jaw and main shaft external diameter, and under the effect of its spring force, make the lozenges in jaw rear end and wedge throw-out collar be close to.
The jaw of holding workpiece is arranged in the radial hole of main shaft by the present invention, and does centripetal moving along the radial hole of main shaft while of by rotating wedge throw-out collar and making the lozenges wedge in it push away three jaws, thus realizes the object of workpiece in double end clamping spindle hole.All do not take spindle hole space owing to forming all components of the present invention, and be point-like clamping, therefore, it is possible to clamp major diameter and the workpiece of complex contour.
The present invention has modern design, rational in infrastructure, versatility good, adaptable advantage.
Accompanying drawing explanation
Accompanying drawing 1 is main sectional structure schematic diagram of the present invention;
Accompanying drawing 2 is A-A cross-section TV structure schematic diagram in accompanying drawing 1.
In attached Fig. 1 and 2: 1 main shaft of head case, 2 main shafts, 3 ring washers, 4 wedge throw-out collars, 401 lozenges, 5 spacer rings, 6 bearings, 7 jaws, 8 springs, 9 workpieces.
Detailed description of the invention
As shown in accompanying drawing 1,2, be provided with spindle hole in main shaft 2, outside axle journal is bearing in main shaft of head case 1 by two bearings 6, and two ends are stretched out outside main shaft of head case 1, and is provided with in the wall portion of external part the radial direction through hole that three are distributed in circumference; On the external diameter of spacer ring 5 matched in clearance inside main shaft 1 external part wall portion radial direction through hole, and by inner axial location; Ring washer 3 fastening main shaft 1 end face, and form by ring washer 3 one end and the rectangular ring groove between spacer ring 5 one end and main shaft 2 external diameter; Be equipped with the jaw 7 of a centripetal slip in three radial direction through hole of main shaft 2 external part wall portion respectively, between jaw 7 and main shaft 2, form moving sets, its one end is stretched in spindle hole, one end inserts in rectangular ring groove; Annular boss is provided with in the middle part of wedge throw-out collar 4 endoporus, boss face is provided with three sections and has identical profile and the even lozenges 401 being distributed in circumference, the point of 120 ° that three sections of lozenges 401 are often separated by is equal to the distance of wedge throw-out collar 4 axis, boss side annular distance coordinates with spacer ring 5 crest clearance, opposite side annular distance coordinates with ring washer 3 crest clearance, boss both sides and endless groove both sides matched in clearance; Spring 8 is placed between jaw 7 and main shaft 2 external diameter, and under the effect of its spring force, make the lozenges 401 in jaw 7 rear end and wedge throw-out collar 4 be close to.
