Abstract
The utility model provides a main shaft (9) are gone up and are installed fixed snail that lathe spindle indexing means, it is stretching out the headstock outside to one externally mounted of headstock can slide adjusting the slide, the slide on install the worm, the worm drive with step motor, worm gear's meshing or separation can be realized in different positions of slip through the slide to realize the graduation to the main shaft with this, the utility model discloses have and the accuracy higher, simultaneously still have self -locking function, can satisfy the lathe after axle type or dish type work piece are accomplished in processing, the direct processing requirement in keyway, screw hole or hole on counter shaft class or the dish type work piece on the lathe.
Description
Technical field
The utility model relates to lathe, is specifically related to lathe spindle indexing means, belongs to lathe-techniques field.
Background technology
Lathe is the mechanical manufacturing tools generally used, and the overwhelming majority that lathe is processed is axle class, disc type work, these workpiece complete cylindrical, after end face processing technology, generally also will cylindrical on this kind of workpiece, the positions such as end face process keyway, hole, screw threads etc., due to keyway, hole, screw threads etc. are generally the distributions in rule at the cylindrical of axle and end face, and lathe does not have calibration function, thus, this kind of workpiece is generally unload from lathe after completing cylindrical and end face processing, is installed to afterwards above milling machine or other corresponding lathe again and completes follow-up processes, and when workpiece is larger, handling are also bother very much and time-consuming thing, meanwhile, the purchase cost of milling machine or drilling machine and processing cost are very high, and such processing method efficiency is low, poor stability, cost is high, precision is poor, if the main shaft of lathe has calibration function, so, this kind of workpiece after completion of processing, lathe is installed corresponding device on lathe, then can reach keyway on workpiece, the object of screw thread and hole machined.
Summary of the invention
The purpose of this utility model is: can not calibration for existing lathe spindle, and cannot adapting to of bringing thus some axle classes or disc type work are processed the defect that keyway, screwed hole and hole require, a kind of lathe spindle indexing means is provided, meet on some axle classes or disc type work, on lathe, directly process the technological requirement in keyway, screwed hole and hole.
The utility model realizes the technical scheme that above-mentioned purpose adopts: described lathe spindle indexing means, it comprises Lathe Spindle Box, and lathe spindle, it is characterized in that: install on the main shaft stretching out main spindle box outside and fix a worm gear, main spindle box below worm gear installs a base plate by bolt first, described base plate both sides are provided with guide rail, sliding floor is provided with between two guide rails, described sliding floor both sides are shaped with symmetrical strip hole, one or two bolt second are set in each strip hole, the threaded portion of described bolt second is screwed into the screwed hole be arranged on base plate, tighten or unclamp bolt second, just can fix or unclamp sliding floor, between sliding floor and base plate, an adjusting bolt is each side set, forward or reverse two adjusting bolts, the motion up or down of sliding floor relative to base plate can be realized, sliding floor immediately below worm gear center line installs a worm screw with two axle bed seats, under the effect of adjusting bolt, worm screw can contact the engagement realizing transmission with worm gear, or from engaging each other the state that State Transferring is disengaging mutually, the sliding floor in worm axis direction is installed and fixes a stepper motor, described step motor shaft is connected with worm shaft.
Beneficial effect: in the utility model, because stepper motor can turn over arbitrary angle under program control on request, and precision is higher, in addition there is good auto-lock function between Worm Wheel System, so, not only can realize the arbitrary indexing to main shaft, and accuracy is higher, also there is auto-lock function simultaneously, lathe can be met after machining axle class or disc type work, directly on lathe to the processing request in keyway on axle class or disc type work, screwed hole or hole.
