Abstract
The utility model belongs to the field of machining and provides a work-piece retaining device for avoiding hidden danger of axial slippage of work-pieces when a machine tool machines the shaft type work-pieces at present. The work-piece retaining device comprises a Morse taper shank, and one end of the Morse taper shank is installed in cooperation with a taper hole of a spindle of the machine tool. The work-piece retaining device is characterized in that the other end of the Morse taper shank serves as the free end and is provided with a screw hole towards the interior of the Morse taper shank, a locating screw entering and exiting from the screw hole freely is arranged inside the screw hole, the tail end of the locating screw extends out of the screw hole, and a locking nut used for locking the locating screw is arranged at the free end of the Morse taper shank. By adopting the work-piece retaining device, axial slippage of the shaft type work-pieces in the machining process can be effectively prevented, the machining accuracy can be guaranteed, and the potential safety hazards are eliminated.
Description
Technical field
The utility model belongs to field of machining, is arranged on the workpiece backstopping device using on lathe while relating in particular to a kind of working shaft-like workpiece.
Background technology
On lathe, when working shaft-like workpiece, axle, under the effect of cutting force, affect axial dimension precision, or after there is axial slip, workpiece disengaging is top, causes the accident thereby easily produce axial slip in chuck.
Summary of the invention
For solving the hidden danger of current lathe workpiece generation axial slip when the working shaft-like workpiece, the utility model provides a kind of workpiece backstopping device.
The technical solution adopted in the utility model is: workpiece backstopping device, comprise a Morse taper shank, one end of Morse taper shank coordinates installation with tapered bore of machine tool spindle, it is characterized in that: the other end of described Morse taper shank has screw as free end to Morse taper shank inside, in screw, be provided with the dog screw freeing in and out, the tail end of dog screw stretches out screw, and the free end of Morse taper shank is provided with the locking nut for locking positioning screw.
This workpiece backstopping device is simple in structure, easy for installation, by adjusting the extension elongation of dog screw to adapt to the retaining requirement of different length shaft-like workpiece.Adopt this workpiece backstopping device can effectively prevent that shaft-like workpiece from axial slip occurring in process, guarantee machining accuracy, eliminated potential safety hazard.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is that this workpiece backstopping device uses view.
In figure, 1, Morse taper shank, 2, free end, 3, screw, 4, dog screw, 5, locking nut, 6, machine tool chief axis, 7, workpiece chuck, 8, shaft-like workpiece, 9, top.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, workpiece backstopping device, comprise a Morse taper shank 1, the smaller diameter end of Morse taper shank is as installation end, the other end of described Morse taper shank is as free end 2, and free end 2 has screw 3 to Morse taper shank inside, is provided with the dog screw 4 freeing in and out in screw 3, the tail end of dog screw 4 stretches out screw 3, and the free end 2 of Morse taper shank is provided with the locking nut 5 for locking positioning screw.
The concrete use of this workpiece backstopping device as shown in Figure 2, coordinate forming Morse's taper in the taper hole of the smaller diameter end insertion machine tool chief axis 6 of Morse taper shank 1, one end of shaft-like workpiece 8 and top 9 offsets, workpiece chuck 7 clamps shaft-like workpiece 8, the extension elongation of adjusting the dog screw 4 on Morse taper shank 1 offsets dog screw 4 and the end of shaft-like workpiece 8, then utilizes locking nut 5 that the extension elongation of dog screw 4 is locked.Add man-hour, the two ends of shaft-like workpiece are propped up by end top and dog screw 4 respectively, can prevent that cutter is in the time of the application of force, shaft-like workpiece generation axial slip.
