Abstract
The invention discloses a lathe center. The lathe center comprises a plug screw, a spring, a Mohs taper, a mandrel center and an end face sharp tooth pusher dog; the plug screw is connected to the left end of the Mohs taper in a threaded manner, the end face sharp tooth pusher dog is connected to the right end of the Mohs taper in a threaded manner, and the diameter of the right end face of the end face sharp tooth pusher dog is 2 mm to 5 mm smaller than the diameter of a workpiece; sharp teeth are arranged on the end face of the end face sharp tooth pusher dog, and the mandrel center is arranged on an inner hole of the Mohs taper in a movable fit manner; and the spring is installed between the plug screw and a shaft shoulder of the mandrel center in a press fitting manner. By means of the lathe center, no-shutdown end face pulling is achieved, centering and pulling are combined, and the machining speed and quality are greatly improved.
Description
Technical field
The invention belongs to clamping tool for machine work technical field, is a kind of lathe centre specifically.
Background technology
When engine lathe is processed small shafts part, in order to improve crudy and speed, normal employing heads on the two ends of processed axle, namely a top left end heading on processed axle is entered in lathe main axis hole interpolation, with the top right-hand member heading on processed axle of tail stock, and the method using heart-shaped fixture to carry out carry-over moment is processed, though this processing method energy one-time positioning, processed axle is made not need to reverse end for end turning, but heart-shaped fixture is the external diameter carry-over moment blocking processed axle, clamping bothers, often process an axle will to stop clamping, dismounting once, so also inconvenient when using, increase the labour intensity of operator, reduce actual work efficiency.
Summary of the invention
The invention provides a kind of lathe centre, for solving the problem.
Technical scheme of the present invention is: a kind of lathe centre, comprise the top and end face pointed tooth pusher dog of plug screw, spring, Mohs cone, axle, plug screw is coupled to Mohs cone left end threadably, end face pointed tooth pusher dog is coupled to Mohs cone right-hand member threadably, the right side diameter 2 ~ 5mm less of the diameter of workpiece of end face pointed tooth pusher dog, its end face arranges pointed tooth, Mohs cone endoporus arranges axle with movable fit system top, pressure mounting of the spring is between plug screw and the top shaft shoulder of axle.
The invention has the beneficial effects as follows: do not stop face driver, top and stir and unite two into one, process velocity and quality improve greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
See Fig. 1, a kind of lathe centre, comprise plug screw 1, spring 2, Mohs cone 3, axle top 4 and end face pointed tooth pusher dog 5, plug screw 1 is coupled to Mohs cone 3 left end threadably, end face pointed tooth pusher dog 5 is coupled to Mohs cone 3 right-hand member threadably, and the right side diameter 5mm less of the diameter of workpiece of end face pointed tooth pusher dog 5, its end face arranges pointed tooth, Mohs cone 3 endoporus arranges axle top 4 with movable fit system, and spring 2 is fitted between the shaft shoulder of plug screw 1 and axle top 4.
Add man-hour, first Mohs cone 3 of the present invention is inserted in lathe main axis hole, then workpiece left end central aperture axle top 4, shake tail stock handle, make that tail stock is top heads on workpiece right-hand member centre bore, make the pointed tooth end face of workpiece left side and end face pointed tooth pusher dog 5 be close to simultaneously, now can start lathe and start processing, after completion of processing, unclamp tail stock, under the effect of spring 2, axle top 4 displacement to the right, and promote workpiece displacement to the right, thus workpiece left side is separated with the pointed tooth end face of end face pointed tooth pusher dog 5, workpiece is caught with hand, workpiece will fall automatically, achieve the dress of the face driver that do not stop, folder, unload overall process.
