Abstract
The utility model discloses a device for cutting and milling internal keyways on various machine tools, belonging to the mechanical process. The power transmission mechanism is composed of a driving gear, a synchronous tooth belt and a driven gear. A milling cutter and the driven gear are connected rigidly, rotate synchronously, center by the action of a guide plate and save the working procedure of streaking, testing, etc. The utility model has the advantages of high efficiency and high precision. The utility model can process the symmetric keyway, the inner spline and also the hard wording position of partly ring groove at the root of the keyway and can be used on the lathe, the planer, the slotting machine and the boring machine.
Description
The equipment of machining inner hole key slot generally is slotting machine or broaching machine.The former efficient is low, low precision, and latter's equipment and cutter costliness, cost is higher.
Inner hole key slot milling attachment for multiple lathe is used then designs at above problem.The power drive mechanism that it is made up of driving gear, synchronous cog belt and driven gear becomes traditional linear reciprocating motion into rotatablely moving, thereby improves stock-removing efficiency, guarantees product quality and reduces production costs.
Structure of the present utility model such as Fig. 1.Its top is front view and partial sectional view, and the below is a vertical view.One-level driven gear (17) and the engagement of one-level driving gear (the one-level driving gear is started separately by ad hoc motor, and the mode that motor is installed is decided by the concrete operating position of various lathes).Axle (15) and single-row centripetal bearing (16), the shank of packing into together has the live bearing shell (13) of slot, one group of movable axis bearing of being regulated by screw (11) has been formed with one-level driven gear and secondary driving gear (14) rigid connection in the axle two ends.Back-up ring (12) is equipped with in the both sides of secondary driving gear, make synchronous cog belt (7) reposefully power is delivered to secondary driven gear (3), because the bottom of this gear tooth slot has the radial symmetric screw and the milling cutter shank has the radial symmetric shallow bore hole, so screw (5) plays the key effect, gear driven milling cutter (4) is rotation synchronously.For making milling cutter not produce excessive axial float, single thrust bearing (6) embeds the secondary driven gear, in the cutter hub (9) of packing into together again.The outside of guide plate (8) is the garden cylinder, and opposite side has groove, and the both ends of the surface outside is the garden conical surface, so that prospect hole.Cover plate (2) and screw (1) peace need the loading and unloading guide plate.Fixed support plate (10) is in order to fastening with various lathes.
The utility model device, easy to operate, it can be contained in lathe, slotting machine, uses in planer, milling machine and the boring.Work piece need not be rule, by the leading part prospect hole centering of guide plate.Guide plate and milling cutter series matching, as process the flat key groove in 58～65 these group apertures, its groove width is all identical with groove depth, so can select 18 special milling cutter for use, during the keyway in this group aperture of milling, need not change milling cutter and cutter hub, as long as change corresponding guide plate.Because the milling cutter shank has the radial symmetric hole, so the milling cutter extension elongation can pacify and need to regulate, to adapt to the dissimilar keyway degree of depth.Guide plate and aperture are matched in clearance, make the feeding track of milling cutter not depart from the error range of permission, thereby guarantee the requirement of keyway to the center.The feed speed of milling cutter is needed to adjust by the feed mechanism peace of lathe.After milling puts in place, feed reversing, withdrawing on the one hand improves the surface roughness of keyway on the other hand.The dimensional accuracy of keyway is by the precision control of milling cutter.
The utility model device is installed on the lathe and uses, but turnning and milling once finish, help improving machining accuracy, if be installed in planer or insert degree and go up and use, then need adjust the stroke speed of lathe, use on milling machine or the boring machine and be installed in, then make things convenient for manyly.
During the processing internal spline, its key is wide to be different from flat key deeply with key, therefore can select suitable cutter hub and guide plate for use, the Worker's Stadium is clipped on the dividing head processes.
The utility model device removes the processing inner hole key slot, outside internal spline and the symmetrical keyway, can also process other difficult working position, the local annular groove of keyway root for example not coming out etc., and this has opened up thinking to New Product's Design.The efficient and the precision that improve inner hole key slot processing are mechanical industry questions of common interest, so the utility model device is as machine tool accessories, and its market is extensive, and economic benefit is rather considerable.
Claims (5)
1, the inner hole key slot milling attachment used of the multiple lathe of a kind of confession.It is characterized in that live bearing shell (13) is equipped with one-level driven gear (17) and secondary driving gear (14).Live bearing shell and cutter hub (9) are fastening.Synchronous cog belt (7) respectively with secondary driving gear, secondary driven gear engagement.Milling cutter (4) is fastening with the secondary driven gear, and guide plate is equipped with in the cutter hub both sides.
2, device according to claim 1 is characterized in that secondary driven gear (3) has the screw of radial symmetric.
