Abstract
The invention provides a lathe main shaft positioning structure. The lathe main shaft positioning structure comprises a Morse cone, a washer, a nut and a screw rod, wherein a thread through hole is formed in a central shaft of the Morse cone; the washer is fixed at the right end of the Morse cone; the screw rod penetrates through the washer, is mounted in the thread through hole of the Morse cone, and is in thread matching; and the nut coats the screw rod, is mounted at the other end of the washer, and is in threaded matching with the screw rod. The lathe main shaft positioning structure can effectively control axial length sizes of batch parts for workpieces with different model numbers through the adjustable structure, so that the adaptability is largely improved, the design and production costs of a positioner are largely reduced, the application range is wide, and the application is convenient and quick.
Description
Technical field
The present invention relates to a kind of locating structure for lathe spindle, belong to for locator field.
Background technology
In prior art, the main shaft orientation of numerically controlled lathe generally all needs the locator of plurality of specifications, select for different bearing rules, particularly for off-gauge Coupling bearing, often need the locator that production specification targetedly conforms to, very bother, and cost also improves thus greatly.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of locating structure for lathe spindle, this locating structure for lathe spindle is by adjustable structure, for the workpiece of different model, can effectively control part volume axial length dimension, thus greatly improve applicability, greatly reduce the cost of positioner designs, production aspect thus.
The present invention is achieved by the following technical programs.
A kind of locating structure for lathe spindle provided by the invention, comprises Mohs cone, packing ring, nut, screw rod; Described Mohs cone axis is provided with tapped through hole, is fixed with packing ring at the right-hand member of Mohs cone; Described screw rod to be arranged in the tapped through hole of Mohs cone through packing ring and screw thread coupling; Described nut sleeve is loaded on other end screw rod being arranged on packing ring, and nut and screw flight coupling.
Described Mohs cone is contained in the mohs tapered bore of machine tool chief axis shaft core position, and Mohs cone and mohs tapered bore form fit.
The end of described screw rod is set to square.
The thread surface of described screw rod is the regular screw threads that pitch is less than 2mm.
Beneficial effect of the present invention is: by adjustable structure, for the workpiece of different model, can effectively control part volume axial length dimension, thus greatly improve applicability, greatly reduce the cost of positioner designs, production aspect thus, applied range, convenient to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-Mohs cone, 2-machine tool chief axis, 3-packing ring, 4-nut, 5-screw rod, 6-machine chuck, 7-processing work, 8-mohs tapered bore.
Detailed description of the invention
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of locating structure for lathe spindle as shown in Figure 1, comprises Mohs cone 1, packing ring 3, nut 4, screw rod 5; Described Mohs cone 1 axis is provided with tapped through hole, is fixed with packing ring 3 at the right-hand member of Mohs cone 1; Described screw rod 5 to be arranged in the tapped through hole of Mohs cone 1 and screw thread coupling through packing ring 3; Described nut 4 is set in other end screw rod 5 being arranged on packing ring 3, and nut 4 and screw rod 5 screw thread coupling.
Described Mohs cone 1 is contained in the mohs tapered bore 8 of machine tool chief axis 2 shaft core position, and Mohs cone 1 and mohs tapered bore 8 form fit.
The end of described screw rod 5 is set to square.
The thread surface of described screw rod 5 is the regular screw threads that pitch is less than 2mm.
During use, according to the processing parts of different length, clamp the square of screw rod 5 right-hand member with spanner and rotate, the extension elongation of adjusting screw(rod) 5; After the length of screw rod 5 is determined, fastening nut 4, then locates the end face of the end face of screw rod 5 and processing work 7, has located with machine chuck 6 clamping machining workpiece 7, can process subsequently to the shaft shoulder end face of processing work 7.After the axial dimension determining initial workpiece processing work 7, processing thereafter can simply pick and place, and adjusts without the need to carrying out again or measures.
