Description
Technical field
The utility model relates to a kind of machine tool accessories, especially a kind of machine tooling rapid fixing of working shaft-like product.
Background technology
When making the machine tooling shaft-like workpiece at present, earlier make a call to a centre bore at an end of workpiece, thimble with centre bore and lathe one end aligns then, one end of workpiece is fixed on the chuck, workpiece fixes the back and just can advance to have processed, and this processing method will be carried out owing to fixedly the time fastening with the chuck key of special use, also will unclamp with the chuck key after the processing, it is long to be used in the fixing loosening time, so the efficient of processing is not high.
The utility model content
The purpose of this utility model is to provide a kind of machine tooling rapid fixing, is characterized in that the fixing and dismounting speed of workpiece is fast, has improved operating efficiency greatly.
Following technical scheme is provided for achieving the above object:
A kind of rapid fixing of machine tooling, it is characterized in that: comprise pedestal, thimble, fixed claw and elastic device, pedestal is fixed on the main rotating shaft of lathe, thimble and elastic device are contained in the through hole of inside of pedestal, elastic device one end is screwed in the through hole of pedestal, the other end is connected with thimble, and the top part of thimble is exposed at the through hole outside, and fixed claw is socketed in the front end of pedestal.
Described fixed claw front end is processed to dentation, has several grooves on the rear end.
Described pedestal front end has several hydraulic cylinders, matches in the quantity and the position of the groove of hydraulic cylinder number of openings and position and fixed claw, and each hydraulic cylinder bottom is interconnected.
Described fixed claw is by base and shrink pawl and forms, and base is inboard and shrink the pawl outside and all is provided with an inclined-plane, and the contraction pawl is placed in the base, and two inclined-planes are close to and are combined.
The utility model is when longilineal workpiece such as working shaft-like, only need to make a locating hole respectively at the two ends of the workpiece that will process, with the workpiece axial location on the thimble of two end, the tailstock top is hard then advances, and the thimble indentation makes the contacts side surfaces of fixed claw and workpiece, and dentation one end blocks processing work firmly, make lathe work be unlikely to processing work and skidding occurs, after the processing, only need workpiece is taken off in the hard recession in tailstock top; Advantage of the present utility model is: need fix with the chuck key when having avoided with chuck fixedly, and then loaded down with trivial details operation such as open, improve working (machining) efficiency greatly.

The specific embodiment
As shown in Figure 1, 2, a kind of machine tooling rapid fixing comprises pedestal 1, fixed claw 2, thimble 3 and elastic device 4, thimble 3 and elastic device 4 are contained in the through hole 13 of pedestal 1 inside, elastic device 4 is to be screwed on the through hole 13 of pedestal 1, the other end of elastic device 4 is connected with thimble 3 afterbodys, and the front end of thimble 3 is exposed at the outside of through hole 13; Fixed claw 2 just is socketed on the front end face of pedestal 1; The front end of fixed claw 2 is established dentation card tooth 21, has three grooves 22 on the rear end, also has three hydraulic cylinders 11 on the front end face of pedestal 1, all is provided with hydraulic pressure plug 12 in the hydraulic cylinder 11, and the top of hydraulic pressure plug 12 holds in the groove 22 of fixed claw 1; Above-mentioned elastic device 4 is made up of connecting screw 43, disk spring pad 42 and location spiral shell 41 bolts.
When processing work, as shown in Figure 5, on processing work 7, make a call to two fixing holes, with thimble 3 axial restraints on tailstock top heavily fortified point and the rapid fixing on the lathe, tailstock top hard 6 advances processing work 7 is compressed then, in compaction process, thimble 3 on the rapid fixing will compress the elastic device 4 that connects later, at this moment the dish-shaped spring shim 42 of elastic device 4 bolts, 41 compressions, because connecting screw 43 is screwed on the pedestal 1, so bolt 41 will move backward, simultaneously the thimble 3 on the rapid fixing also will move backward, and the dentation card tooth 21 of fixed claw 2 front ends can be held on the side of processing work 7 firmly, and workpiece 7 can not skidded adding man-hour, pipette down processing work 7 as long as machine after making tailstock top hard 6, accelerated the speed of processing greatly; In addition when running into processing work 7 sides and axis out of plumb, because pedestal 1 front end face is provided with hydraulic cylinder 11, hydraulic pressure plug 12 in the hydraulic cylinder 11 holds in the groove 22 of fixed claw 2 rear ends, will make 2 pairs of hydraulic pressure plugs of fixed claw 12 produce different pressure, make hydraulic pressure plug 12 produce displacement, make the dentation card tooth 21 of fixed claw 2 front ends consistent, reach the requirement of processing with the angle of processing work 7 sides.
The another kind of embodiment of the utility model, shown in Fig. 6,7, narrating fixed claw 5 is made up of base 51 and contraction pawl 52, shrinking pawl 52 is placed in the base, base 5 is provided with an inclined-plane 510, also be provided with an inclined-plane 520 on the pawl 52 and match with inclined-plane 510 on the base 5 shrinking, contraction pawl 52 inside also are provided with projection 521; Add man-hour, processing work holds on the projection 521 that shrinks pawl 52 inside, when the hard propelling in tailstock top compresses processing work, processing work withstands on the projection 521 that shrinks pawl 52, processing work can push and shrink pawl 52, and contraction pawl 52 is moved inward, owing to all be provided with the inclined-plane on base 51 and the contraction pawl 52, the interior bone of shrinking pawl 52 is shunk, processing work is firmly fastening.
