Abstract
The invention belongs to the field of machining and provides a retreating stopper of a workpiece for eliminating the potential hazard that workpieces slide axially when an existing machine tool is used for machining the axle type workpieces. The retreating stopper of the workpiece comprises a Mohs drill handle, and one end of the Mohs drill handle and a main shaft drill hole of the machine tool are mounted in a matching manner. The retreating stopper of the workpiece is characterized in that the other end of the Mohs drill handle serves as a free end and a screw hole is arranged inside the Mohs drill handle, a positioning screw capable of accessing freely is arranged in the screw hole, a tail end of the positioning screw hole extends out of the screw hole, a locknut used for locking the positioning screw is arranged at the free end of the Mohs drill handle. By the aid of the retreating stopper of the workpiece, the axle type workpieces can be effectively prevented from sliding axially during machining, machining precision is guaranteed, and potential safety hazards are eliminated.
Description
Technical field
The invention belongs to field of machining, while relating in particular to a kind of working shaft-like workpiece, be arranged on the workpiece backstopping device using on lathe.
Background technology
On lathe, during 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 invention provides a kind of workpiece backstopping device.
The technical solution used in the present invention 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, and the extension elongation by adjusting dog screw is 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 invention.
Accompanying drawing 2 is that this workpiece backstopping device is used 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 present invention will be further described.
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, by forming Morse's taper in the taper hole of the smaller diameter end insertion machine tool chief axis 6 of Morse taper shank 1, coordinate, one end of shaft-like workpiece 8 and top 9 offsets, workpiece chuck 7 clamping shaft-like workpieces 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 when the application of force, shaft-like workpiece generation axial slip.
Claims (1)
1. 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.
