Description
Technical field
The present invention relates to a kind of truning fixture, relate in particular to a kind of can be simultaneously axially and the rotating turnery head of cutter of radially feed and have the lathe of this working head.
Background technology
Need be to two ends through the bar axial workpiece of processing, as turning, grooving, face work, processing such as chamfering operation, existing process equipment, no matter be machine tool, instrument lathe, Digit Control Machine Tool, it clamps an end earlier with the anchor clamps on their headstocks often at processing bar axial workpiece, the processing other end, then part is reversed end for end, an end of having processed with clamp clamps, process a still unprocessed end, just want the secondary clamping respectively, secondary operations just can be finished, labour intensity is big concerning the operator, production efficiency is low, and the secondary clamping also influences the machining accuracy of part, and also is not suitable for producing in enormous quantities.
It is that the Chinese utility model patent " workpiece state type revolving body processing machine " of ZL93225021.1 (notification number is CN2147056Y) has disclosed a kind of such structure that one patent No. is arranged, a kind of workpiece state type revolving body processing machine, formed by clamping work pieces mechanism, truning fixture, operating mechanism, shaft coupling, decelerator, motor, stand and support, it is characterized in that: a. truning fixture: comprise pattern, cutterhead and main shaft, pattern is a hollow circle tube, is arranged on the stand; Main shaft passes pattern, is with cutterhead on its section of passing; Pattern, cutterhead and main shaft three's the center of circle is on same straight line; B. cutterhead comprises: at the bottom of the cutterhead, cutterhead lid and lathe tool; Cutterhead is the disk of hollow, has groove on the plane at the bottom of the cutterhead, and lathe tool is housed in the groove, be packed in cutterhead lid at the bottom of the cutterhead by screw on; C. on another section of main shaft, be set with taper roll bearing and tighten up nut; Tighten up on the end face that nut abuts against taper roll bearing; Suit one sliding sleeve again on the periphery of taper roll bearing is provided with a chute on the top of sliding sleeve, and a tooth bar is arranged on its underpart, and sliding sleeve is arranged in the housing of operating mechanism; Anti-twist lock is housed in the hole on housing top, control crank also is housed on its downside, and is set with wheel and rack phase bridle joint on the control crank, housing is fastened on the stand.The electric machine main shaft rotation when work of this processing machine also moves axially left, the roller at knife bar top abuts against to rotate on the pattern inwall and moves, spring forces roller on the knife bar near pattern, radially forming movement depends on the pattern shape, the inwall of pattern takes the form of inclined plane, and roller is not really stable in the rolling of pattern inwall relatively, only depends on spring that the inwall that roller is pressed on pattern is seemed unstable, easily skid, so there is the not high defective of machining accuracy in above-mentioned processing machine.
It is that the Chinese utility model patent " head of long-tube or long-axle parts machine-tool for comprehensively machining " of ZL01114307.X (notification number is CN1393319Y) has disclosed a kind of head of long-tube or long-axle parts machine-tool for comprehensively machining that one patent No. is arranged again, it comprises frame, clamping device, holding device, feed screw nut's axial feed system, radial tool post, radially feeding system, swivel mount, headstock, an end that it is characterized in that frame is equipped with clamping device, the other end feed screw that is connected, the female silk of a feeding is contained in the head of screw mandrel; On screw mandrel, be with a hollow shaft that can only slide and to rotate, the housing of swivel mount passes through two place's bearing holder (housing, cover)s on hollow shaft, housing one end face of swivel mount is equipped with one or more radial tool posts of doing radial motion, links to each other with headstock by power gear, splined shaft on the other end; Install a central gear on the hollow shaft, one or more groups feed gear wheel and change gear are installed between central gear and the female silk of feeding, one or more groups feed gear and change gear are installed between the feed screw mandrel of central gear and radial tool post, every group of feeding change gear is provided with a clutch, and every group of feed change gear also is provided with a clutch.During work, when power gear makes the swivel mount rotation, feed gear wheel group and gear changing group are by the engagement of the central gear on the hollow shaft, the female silk of form drive that is the NW Gear Planet Transmission rotates on screw mandrel, thereby finish the action of the axial feed of swivel mount, thereby feed gear train and gear changing group drive the feed screw mandrel rotation (not having the planet effect this moment) of feed support by the engagement of the central gear on the hollow shaft finish radially feed, because this machining tool will rely on a plurality of gear trains to cooperate in the feed process, and the structure of gear train is relatively very complicated, the inconvenience assembling, the entire mechanism volume is big, it is many to relate to parts in the transmission process, and structure is not quite reasonable.
Summary of the invention
Technical problem to be solved by this invention is that a kind of compactness rational in infrastructure, the rotating turnery head of cutter easy to assembly are provided at above-mentioned prior art present situation, the axial feed of this working head and radially feed is steady is so also have the high advantage of machining accuracy.
Another technical problem to be solved by this invention provides a kind of lathe for machining of having used the rotating turnery head of above-mentioned cutter, this lathe can make workpiece finish processing operations such as turning, grooving, face work, chamfering under a clamping job, be fit to produce in batches, improved working (machining) efficiency.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the rotating turnery head of a kind of cutter, but including the main transmission section of main shaft, cutter, tool rest, drive shaft rotation, described tool rest links to each other with main shaft also can be with main axis rotation; It is characterized in that also comprising: a feed running part, include pull bar, the pull bar activity is arranged in the main shaft, front end at pull bar is fixed with driving cam, driving shaft, driving cam and driving shaft are positioned at tool rest, the rear end of pull bar with can drive the actuator that pull bar, driving cam and driving shaft move back and forth vertically simultaneously and link to each other; One moves the tool rest parts: include movable blade pedestal, knife rest, spring, the movable blade pedestal can move axially along tool rest also can be spacing rotatably in tool rest with tool rest, knife rest can move radially along the movable blade pedestal also can be spacing rotatably on the movable blade pedestal with the movable blade pedestal, tool-holder is held on the knife rest, and spring is located on the knife rest to apply the radially reset force of a relative movable blade pedestal to knife rest; One axial feed mechanism: comprise axial swing arm, axially on the middle part rotatable support tool rest of swing arm, but what axially end in contact made driving cam behind an end of swing arm and the driving cam moves axially impeller-hub to swing arm deflection, and its other end then links to each other with the movable blade pedestal so that the deflection of axial swing arm can promote the relative tool rest of movable blade pedestal moves axially; One depth-feed mechanism: comprise radially swing arm, radially the middle part rotatable support of swing arm is on the movable blade pedestal, driving shaft is provided with and the groove that matches of swing arm radially, radially an end of swing arm be positioned at corresponding groove so that groove move axially the deflection that can drive radially swing arm, the outer face of its other end and knife rest directly or indirectly conflict so that radially the deflection of swing arm can promote the relative movable blade pedestal of knife rest and move radially.
