The purpose of the utility model is achieved in that a kind of numerical control axle revolution location reducing mill stand pass numerically controlled lathe; It comprises the revolution numerical control cutterhead part that is installed on the lathe base, open and subtract frame and drive localization part, cutter rotary driving machine support body and screw mandrel Rack Body; Said revolution numerical control cutterhead partly links to each other with cutter rotary driving machine support body through the contrate gear pair, links to each other through line slideway auxiliary between cutter rotary driving machine support body and the leading screw Rack Body.
Said revolution numerical control cutterhead partly comprises knife bar, cutterhead Rack Body and is installed on servomotor I and the line slideway on the cutterhead Rack Body; The roller leading screw that is parallel to the cutterhead Rack Body is installed on said line slideway; One end of said roller leading screw links to each other with the output of servomotor I; Said knife bar is installed on line slideway through the tool rest planker, and the tool rest planker links to each other with the roller leading screw.
Said leading screw Rack Body is provided with the leading screw that is parallel to cutterhead Rack Body axial line, and said leading screw links to each other with cutter rotary driving machine support body through the roller screw.
Compared with prior art, the beneficial effect of the utility model is:
The utility model utilizes the two-axis numerical control system just can carry out the processing of multistage junction curve respectively to the roll pass of three positions; Realize the processing of any kind pass, improve working (machining) efficiency on the one hand, reduce entreprise cost; Simple in structure easy to operate because of it on the other hand, reduce the later maintenance expense.

The specific embodiment
Referring to Fig. 1; The utility model relates to a kind of numerical control axle revolution location reducing mill stand pass numerically controlled lathe, and it is mainly by being installed on revolution numerical control cutterhead part 1 on the lathe base, opening and subtract frame and drive localization part 2, cutter rotary driving machine support body 3 and screw mandrel Rack Body 4 and form.Said revolution numerical control cutterhead part 1 is installed on the cutter rotary driving machine support body 3 through fluted disc 5, links to each other through line slideway auxiliary between cutter rotary driving machine support body 3 and the leading screw Rack Body 4.
Said subtracts frame and drives localization part 2 and mainly subtract frame 2.1, three rolls 2.2 and motor 2.3 and form by opening.The central axis of three rolls 2.2 forms an equilateral triangle plane, and is as shown in Figure 2, and three rolls are 120 degree and distribute.
Said cutter rotary driving machine support body 3 mainly is made up of cutter rotary worm couple 3.1, cutter rotary drive motors 3.2, hydraulic cylinder 3.3 and cutter running Rack Body 3.4.Wherein cutter running Rack Body 3.4 links to each other with revolution numerical control cutterhead part 1 through contrate gear secondary 5; On the cutterhead part 1 with cutter rotary driving machine support body 3 on the contrate gear that is meshed that has separately; Be to make its flexible disengagement and tighten engagement through hydraulic cylinder 3.3; Link to each other with leading screw Rack Body 4 through line slideway auxiliary at cutter running Rack Body 3.4; Hydraulic cylinder 3.3 cooperates the turned position of the whole revolution numerical control cutterhead part 1 of secondary 5 controls of worm couple 3.1 and contrate gear, tightens behind the cutter rotary, makes roller leading screw 1.5 can be positioned the Roller Machining plane that 120 degree distribute exactly;, hydraulic cylinder 3.3 make revolution numerical control cutterhead part 1 just form a rigid unitary after tightening, stability when guaranteeing turning with cutter rotary driving machine support body 3.
Referring to Fig. 3, revolution numerical control cutterhead part 1 mainly is made up of knife bar 1.1, servomotor I 1.2, cutterhead Rack Body 1.3 and line slideway 1.4.Said cutterhead Rack Body 1.3 is the cylinder disk body; Servomotor I 1.2 is fixed on the transverse plane of cutterhead Rack Body 1.3 with line slideway 1.4; Line slideway 1.4 is provided with parallel and roller leading screw 1.5 transverse plane; Roller leading screw 1.5 links to each other with the output of servomotor I 1.2, on line slideway 1.4, also is provided with tool rest planker 1.6, and knife bar 1.1 is installed on the tool rest planker 1.6.Drive the displacement of tool rest planker 1.6 on line slideway 1.4 by servomotor I 1.2 through roller leading screw 1.5, this displacement is as the motion of knife bar 1.1 at the Z axle.
Leading screw Rack Body 4 mainly is made up of with leading screw 4.3 leading screw support 4.1 and the servomotor II 4.2 that is installed on the leading screw support 4.1.Leading screw 4.3 is parallel to each other with the axial line of the cutterhead Rack Body 1.3 of revolution numerical control cutterhead part 1; One end of leading screw 4.3 is fixed on the leading screw support 4.1; The other end links to each other with the output of servomotor II 4.2 through reducing motor 4.4, and the centre of leading screw 4.3 links to each other with cutter running Rack Body 3.4 through roller screw 4.5.Come driving rotational numerical control cutterhead part 1 and cutter rotary driving machine support body 3 to do straight reciprocating motion by servomotor II 4.2 through leading screw 4.3, this displacement is the motion of knife bar 1.1 at the X axle.
Above-mentioned X axle and Z axle have constituted the motion rectangular coordinate system of knife bar 1.1, are same as the same breaker roll pass of typical machined into form and carry out the turning working motion.And but the coordinate system of this mechanical movement is based upon on the revolution numerical control cutterhead; So when revolution numerical control cutterhead partly turns round respectively contraposition open subtract that frame drives in the localization part 2 three rolls 2.2 that three 120 degree distribute cross axis cutting plane (ideal position of turning), also just formed utilize the two-axis numerical control system just can be respectively to the processing of the roll pass implementation multistage junction curve of position, three spaces (three-dimensional position).
