Abstract
The invention discloses a rotating ejection head of a center frame of a lathe, wherein the rotating ejection head can be used for rotatably fastening a workpiece in an ejecting mode. The rotating ejection head comprises a base and a shell, the shell is in sliding connection with the base horizontally and linearly, a sleeve is arranged in the shell in a sliding connection mode horizontally and axially, the axial direction of the sleeve is perpendicular to the sliding direction of the shell, a rack is fixedly arranged on the sleeve, a gear rotationally connected with the shell is meshed with the rack, the gear is fixedly connected with a handle, an ejection post capable of revolving is arranged in the sleeve in a connected mode through bearings, and the ejection end of the ejection post stretches out of the shell. The shell is in sliding connection with the base so that the horizontal radial displacement of the ejection post can be adjusted; the ejection post can move axially but the sleeve cannot move axially, and therefore the ejection post can rotatably fasten the workpiece in the ejecting mode when freely rotating because of the bearings.
Description
Technical field
The present invention relates to a kind of turned part.
Background technology
In machining, machining large longaxones parts on lathe, or often use centre frame during the large hollow axle of processing with centre bore and make Workpiece fixing, the top of the support that traditional centre frame has, adopts cast iron process usually and end face is arc surface, and the top of this centre frame can not rotate when machinery production uses, during the long deep hole of machining shaft, owing to wearing and tearing in the cylindrical top of long-time back shaft, the position of axle will be changed, will not ensure machining accuracy.
Therefore, need simple, reasonable in design, the convenient and practical top of a kind of structure to ensure machining accuracy in machining, and then improve the quality of products.
Summary of the invention
The invention is intended to provide a kind of lathe center frame rotary jacking head, to realize, rotatable to carry out top to workpiece solid.
Lathe center frame rotary jacking head in this programme, comprise base and housing, housing horizontal linear is slidably connected on base, in housing, horizontal axis has been slidably connected sleeve, and the axis of sleeve is vertical with the glide direction of housing, and sleeve is installed with tooth bar, housing rotates the wheel and rack engagement of connection, gear is connected with handle, and being connected with by bearing in sleeve can the fore-set of rotation, and housing is stretched out in the top of fore-set.
Housing is slidably connected to adjust the displacement of fore-set horizontal radial on base, and fore-set axially can not move axially with sleeve, when because bearing can rotation freely, namely achieves and rotatingly carries out top to workpiece and consolidate.And, by the handle on transmitting gear, the axial location being adjusted sleeve by rack-and-pinion can also be adjusted, stretch out to help fore-set or retract, the convenient dismounting carrying out the installation of workpiece.
Further, on housing, thread connection has screw rod, and the head of screw rod is connected with housing by stage clip.Housing is made axially having certain compressive deformation ability, to make the bearing capacity of housing stronger.
Further, base is slidably connected by dovetail groove and housing.Action is more stable, and processing is safeguarded also more for convenience.
Further, the leading screw of adjustable shell position is provided with in base.Make the adjustment of mechanism more accurate.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: base 1, housing 2, sleeve 3, tooth bar 4, gear 5, radial thrust bearing 6, fore-set 7, screw rod 8, stage clip 9.
Embodiment is substantially as shown in Figure 1: base 1 is fixedly mounted in frame, the top of base is connected with the housing 2 of device by dovetail groove horizontal slip, dial on base connects with the leading screw in base, leading screw by with the screw-internal thread fit on housing to adjust the displacement of housing in dovetail groove.
Be slidably connected sleeve 3 in the housing, sleeve can not according to rotating from axle, the lower right of sleeve is provided with tooth bar 4, the gear 5 that housing upper bearing (metal) connects engages with described tooth bar, gear is fixedly welded with the hand handle stretching out hull outside, rotates hand moving axially by the rotating band carry-over bar of gear and sleeve.
Same, worm and gear can also be used to replace rack-and-pinion, and realize the control to sleeve portion, specifically, worm screw is rotatably connected on housing, and engages with the worm gear of sleeve periphery.
In the left, center of sleeve, its inner rotation by two radial thrust bearings 6 connects fore-set 7, and the left end of fore-set stretches out housing for carrying out top to the workpiece on lathe admittedly.In the right of sleeve, on housing, thread connection has the screw rod 8 of level, and the tail end of screw rod is connected by stage clip 9 with the blind via bottom of sleeve, is moved to the left to order about sleeve.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
