Abstract
The invention relates to a locking mechanism of a milling power head spindle sleeve. A spindle sleeve can be installed in the inner hole of a spindle holder in a slippage mode; a guidance key is respectively arranged in the inner hole keyway of the spindle holder and the excircle keyway of the spindle sleeve; a left latch segment and a right latch segment are installed in the spindle holder by a locking screw and are positioned on the external diameter of the spindle sleeve; the locking surfaces of the left latch segment and the right latch segment are curve surfaces; and the radius of curvature of the curve surfaces is same with the external diameter of the spindle sleeve. An upper set and a lower set of spindle sleeve locking mechanisms are arranged in the spindle holder; the screw is locked in a rotating mode by a wrench to drive the left latch segment and the right latch segment to link to lock the spindle sleeve; therefore, the spindle sleeve can not move axially; the guidance key prevents the spindle sleeve from radially rotating; and the milling operation can be safely and stably carried out so as to fully improve the quality of the workpiece surface.
Description
Technical field
The present invention relates to field of machine tool equipment, especially rotary machine tool.
Background technology
The track installed surface and the pin-and-hole of traffic cycle and large cylinder need be processed; And the processing of the track installed surface of general mini-roundabout and little cylindrical shell can be milled or the vertical lathe completion by rotating disk; Pin-and-hole can be machined by the boring machine boring, but the big rotating disk and the track and the pin-and-hole of large cylinder do not have the heavy duty machine tools apparatus processing.In order to overcome the track installed surface and the pin-and-hole of processing traffic cycle and large cylinder, the big disk swinging of the applicant's research and development is milled the rotary machine tool of boring special equipment.Milling process is an interrupted cut process, and mechanical shock that cutter tooth receives and variations in temperature are all very big.If rack sleeve is axially in milling process, play radially takes place, not only disturbed normal milling process, had a strong impact on the surface quality of workpiece, also can shorten lathe and cutter service life.
Summary of the invention
There is Device for elimination of axial-and radial-play in the applicant to above-mentioned existing milling power head mechanism; Provide a kind of easy to operate; Positioning and reliable clamping milling unit head rack sleeve retaining mechanism, thus be convenient to the milling operation that carries out of safety and stability, fully improved the milling surface quality.
The technical scheme that the present invention adopted is following:
A kind of milling unit head rack sleeve retaining mechanism; The endoporus that is installed on spindle drum of rack sleeve slip; In spindle drum inner hole key slot and rack sleeve cylindrical keyway, be provided with feather key, left latch segment and right latch segment are installed in the spindle drum through tie down screw, are positioned at the rack sleeve outer radius; The locking face of left side latch segment and right latch segment is a curved surface, and its radius of curvature equates with the rack sleeve external diameter.
Rack sleeve retaining mechanism of the present invention two covers up and down is installed in the spindle drum; Drive left latch segment, right latch segment linkage locking rack sleeve with spanner rotational lock screw rod; Rack sleeve axially can not moved; Feather key radially can not rotate rack sleeve, safety and stability carry out milling operation, thereby fully improved the quality of work piece surface.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Like Fig. 1, shown in Figure 2, the present invention includes spindle drum 1, rack sleeve 2, stifle 3, spacer 4, left latch segment 5, tie down screw 6, right latch segment 7, back-up ring 8, taper pin with internal thread 9, cover 10 thoroughly, feather key 11, planker 12.
The present invention is installed on the planker 12 through Bolt Connection by spindle drum 1; Rack sleeve 2 is installed on spindle drum 1 endoporus and slides; Feather key 11 is installed in spindle drum 1 inner hole key slot and the rack sleeve 2 cylindrical keyways through screw; When being moved up and down, plays rack sleeve 2 effect of guiding in spindle drum 1 endoporus; Left side latch segment 5 is installed in rack sleeve 2 outer radius with right latch segment 7 through tie down screw 6, and the locking face of left latch segment 5 and right latch segment 7 is a curved surface, and its radius of curvature equates with the external diameter of rack sleeve 2.Back-up ring 8 is installed on the tie down screw 6 through taper pin with internal thread 9, and spacer 4 is installed in the termination of left latch segment 5, and 1 liang of outer face of spindle drum is installed stifle 3 respectively and covered 10 thoroughly.
During real work; Drive the cylindrical place of left latch segment 5, right latch segment 7 linkage locking rack sleeves 2 with spanner rotational lock screw rod 6; Utilize clamping force and frictional force to make rack sleeve 2 axially can not the moving up and down of spindle drum 1, rack sleeve 2 can not produce under the effect of feather key 11 along the radially rotation of spindle drum 1 endoporus simultaneously; Under the effect of two cover locking mechanisms and positioning key 11, rack sleeve is locked fully, thus again safety and stability carry out milling operation, fully improved the stability of processing and the quality of surface of the work.In like manner with spanner rotational lock screw rod 6 drive left latch segment 5, rack sleeve 2 is unclamped in 7 interlocks of right latch segment, this mechanism is easy to operate, reliable clamping.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
