Abstract
The utility model relates to a driving device for a numerical control cylindrical grinding machine gear shaft workpiece, which comprises a base, driving gear teeth, a driving ring and a driver plate, wherein the base is fixedly connected with the driver plate through a fastening screw; the driving ring is connected with the base through a pin shaft, a limit sleeve and a bolt; in the driving ring, the driving gear teeth is fixedly connected through adopting an inner hexagon screw. When a workpiece is clamped by workers, and is tightly jacked between finials of a head stock and a tail stock, and the workers can check and adjust the driving ring by rotating the workpiece manually, so that the driving gear teeth on the driving ring and the gear shaft workpiece can be meshed. The driving device for the numerical control cylindrical grinding machine gear shaft workpiece has the benefits that the operation is convenient, the structure is simple, the driving ring is connected with the driving gear teeth by the bolt, and the universality is high.
Description
Technical field
The utility model relates to a kind of numerical control external cylindrical grinding machine workpiece driving device, especially relates to a kind of driving device of gear shaft workpiece.
Background technology
At present, gear shaft workpiece driving device conventional on numerical control external cylindrical grinding machine has two kinds, and a kind of is the device that driving lever drives chuck, on headstock driver plate, driving lever is installed, chuck is installed on workpiece, after a tailstock center top tight workpiece, headstock driver plate rotates, and driving lever striking clamp drives workpiece rotation.This structure, need to be on the workpiece that will process clamping head, the secondary process time is long, efficiency is low.Another kind of device, is chuck for installing on the headstock, and due to complex structure, cost compare is high.
Summary of the invention
The purpose of this utility model is low in order to overcome the existing numerical control external cylindrical grinding machine shaft-like work driving device efficiency that cogs, and the shortcoming that cost is high, provides the numerical control external cylindrical grinding machine gear shaft workpiece that a kind of efficiency is high, cost is low, simple to operate driving device.
The utility model solves the technical scheme that its technical problem adopts: a kind of numerical control external cylindrical grinding machine gear shaft workpiece driving device, comprise base, drive tooth, be with moving-coil, driver plate, be characterized in: between base and driver plate, be fixedly connected with by trip bolt, between band moving-coil and base, be connected by bearing pin, stop collar and screw, in band moving-coil, be fixedly connected with drive tooth with soket head cap screw.
Bearing pin on base be connected with the groove fit on moving-coil.Stop collar length is greater than the length with moving-coil.Between band moving-coil and stop collar, all leave gap between stop collar and screw.Between base and band moving-coil, be equipped with multiple springs.Drive tooth upper cover to be useful on the lid entering that prevents cooling fluid.
The beneficial effects of the utility model:
Band moving-coil of the present utility model rotates with base, can have again rotation and movement by a small margin with respect to base, and it is realized by bearing pin, stop collar and screw, and the bearing pin on base is stirred out reeded band moving-coil rotation.Band moving-coil has again screw to be connected with base by stop collar, stop collar length is greater than the length with moving-coil, band moving-coil can move axially along stop collar, between band moving-coil and stop collar, all gapped between stop collar and screw, so rotation and the movement with having between moving-coil and base by a small margin.Between base and band moving-coil, be added with multiple springs, after workpiece is disassembled, under the effect of spring force, can return to initial conditions with moving-coil.
Band moving-coil is connected with screw with driving tooth, for the gear shaft workpiece of different-diameter, only needs to change to drive tooth, does not need to change package unit, for gear shaft workpiece, has improved versatility.
Workman in the time of clamping workpiece, after a tailstock center top tight workpiece, workman's hand rotation workpiece, just can check and adjust band moving-coil, make to engage with gear shaft workpiece with the drive tooth on moving-coil, easy to operate, simple in structure, band moving-coil is connected with screw with driving tooth, highly versatile.
Accompanying drawing explanation
Fig. 1 is sectional structural map of the present utility model;
Fig. 2 is drive tooth structural map of the present utility model;
Fig. 3 is drive ring structure figure of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, numerical control external cylindrical grinding machine gear shaft workpiece driving device of the present utility model, comprises base 1, trip bolt 2, holding screw 3, bearing pin 4, stop collar 5, screw 6, spring 7, drives tooth 8, band moving-coil 9, soket head cap screw 10, lid 11, driver plate 12.
Base 1 is fixedly connected with by trip bolt 2 with driver plate 12, rotates with driver plate 12.Band moving-coil 9 rotates with base 1, can have again rotation and movement by a small margin with respect to base 1, and workman is in the time of clamping workpiece, end to end after top clamping work pieces, workman's hand rotation workpiece, just can make to drive the drive tooth 8 on circle 9 well to engage with gear shaft workpiece, easy to adjust.With being connected between moving-coil 9 and base 1, to realize by bearing pin 4, stop collar 5 and screw 6, the bearing pin 4 on base 1, can stir out reeded band moving-coil 9 and rotate.Band moving-coil 9 has again screw 6 to be connected with base 1 by stop collar 5, stop collar 5 length are greater than the length with moving-coil 9, band moving-coil 9 can move axially along stop collar 5, between band moving-coil 9 and stop collar 5, all gapped between stop collar 5 and screw 6, so with having rotation and movement by a small margin between moving-coil 9 and base 1.
Between base 1 and band moving-coil 9, be added with multiple springs 7, after workpiece is disassembled, under the effect of spring 7 elastic force, can return to initial conditions with moving-coil 9.
Drive tooth 8 to be stamped 11 above, lid 11 is used for covering sawtooth, prevents entering of cooling fluid, extends the service life of fixture.
Band moving-coil 9 is connected with driving tooth 8 use soket head cap screws 10, for the workpiece of different-diameter, only needs to change to drive tooth 8, does not need to change package unit, for gear workpieces, has improved versatility.
At zigzag workpiece during by top holding out against, if the just groove in gear shaft of nose part of driving device just can drive workpiece to rotate.If the nose part of driving device just contacts with gear shaft workpiece bossing, workman's turning of work piece of only need exerting oneself a little, just can adjust band moving-coil, makes to engage with gear shaft workpiece with the drive tooth on moving-coil.
