Description
Technical field
The present invention relates to the improvement of milling machine process equipment auxiliary machine tool, is a kind of miller tailstock addendum cone locking device.
Background technology
The afterbody of milling machine is provided with tailstock, is mainly used for processing the location of long-axle workpieces centre bore; Prior art miller tailstock is comprised of bearing and centre bore addendum cone, and bearing is to adopt bolt to form and be connected with the lathe bed of milling machine, and addendum cone is to be fixedly mounted in the installing hole of bearing; During milling machine processing long-axle workpieces, one end of workpiece is mounted on index dial, and the centre bore of the workpiece other end is mounted on the addendum cone of miller tailstock; The problem that prior art miller tailstock exists is: during milling machine processing long-axle workpieces, and all connecting bolts of necessary dismounting tailstock of each lifting workpiece, the operation of workpiece upper and lower pieces is cumbersome, inefficiency.
Summary of the invention
Object of the present invention will solve the cumbersome and ineffective problem of the existing lifting workpiece operation of existing miller tailstock exactly, and a kind of miller tailstock addendum cone locking device is provided.
Concrete scheme of the present invention is: a kind of miller tailstock addendum cone locking device, and it is provided with frame and milling cutter unit head, and one end of frame is to adopt headstock that index dial is installed, and the other end of frame is provided with tailstock, it is characterized in that: described tailstock is by locking nut, sliding sleeve, addendum cone, bearing, lock dog, tie down screw and clamp composition, the tail end of addendum cone is provided with fine setting screw rod, sliding sleeve is mounted in the installing hole of bearing, addendum cone is mounted in the trepanning of sliding sleeve, fine setting screw rod on addendum cone is to coordinate installation with the screw in sliding sleeve trepanning, locking nut is mounted in addendum cone fine setting screw rod and is positioned at the outside of sliding sleeve, two lock dogs are mounted in the lockhole of bearing installing hole downside, tie down screw is to adopt clamp to be arranged on a side of bearing lockhole, tie down screw is extend in the lockhole that is arranged on bearing and coordinate installation with the screw on two lock dogs, two medial surfaces on two described lock dogs are to contact with the outer arc face of sliding sleeve in limit installation site.
One side of each lock dog of the present invention is equipped with arc surface, and the radius of curvature of each lock dog arc surface is to equate with the radius of curvature of sliding sleeve cylindrical, and two arc surfaces on two described lock dogs are to be in opposite directions to arrange and install in the lockhole of bearing.
Screw thread on tie down screw of the present invention is to consist of two sections of left and right, and the direction of rotation of the two sections of screw threads in left and right is contrary.
The present invention compares with existing miller tailstock, and the present invention fixes with bearing and frame, is the installation that forms addendum cone and bearing with sliding sleeve, regulates tie down screw can realize the movement of addendum cone and fastening, and the fine setting screw rod of adjusting addendum cone tail end can be realized the fine setting of addendum cone; When workpiece needs upper and lower pieces operation, only need degree of tightness tie down screw and fine setting screw rod just can complete the upper and lower pieces operation of workpiece, upper and lower pieces is easy to operate, and operating efficiency is high; The present invention is simple in structure, easy to operate, operating efficiency is high; The present invention preferably resolves the cumbersome and ineffective problem of the existing lifting workpiece operation of existing miller tailstock.
