Abstract
The invention relates to a chuck for a machine tool and belongs to a machine tool accessory technology. According to the invention, an existing chuck, an existing spindle and an existing spindle gearbox are provided with datum line positions, indexing meters are arranged on the spindle and the chuck, and a fastening part and a fixed screw thread are arranged on the chuck. The chuck for the machine tool can obtain a firm clamping effect by using a small clamping force, is suitable for completing machining of a multiple thread and the like under the condition of tool setting and no universal indexing head, and is very suitable for the conditions that few parts of a workpiece can be clamped and the workpiece is difficult to machine.
Description
Technical field
The invention belongs to machine tool accessory technology.
Background technology
Current lathe fixation workpiece instrument roughly has scroll chuck, chuck and floral disc etc., wherein scroll chuck is most widely used general, common mechanical workpiece is take the plate-like workpiece of axle class and flange or similar flange as main, with regard to general processing technology, the axial workpiece overwhelming majority has keyway position, porose or some local fastening technological design having with other workpiece cooperations in the middle of plate-like workpiece, if some part allows the workpiece part of clamping fewer, just easily clamp not strongly the outbound situation of workpiece, this has adverse effect to workpiece and chuck, easily make chuck precision reduce, and, workpiece flies out and likely causes industrial injury or the work accident of dying, if employing boosting-rod, chucking power is excessive, equally the precision of workpiece and chuck is had to adverse effect, in addition, tool setting at present is generally all estimated, general finish turning tool setting requires higher, and multiple-threaded processing, major part is all to utilize universal dividing head, but in quantity situation on the low side, universal dividing head is not very convenient.
Summary of the invention
beneficial effect:the invention reside in and can use smaller chucking power just can obtain firm clamping effect, and applicable tool setting and complete the processing of multiple thread etc. in the situation that there is no universal dividing head.
technical essential:the present invention arranges datum line position at machine tool chief axis gearbox (or holding components of other main shafts) near the position of main shaft and main shaft end face outside and chuck card, on the main shaft position near gearbox (or holding components of other main shafts) and chuck, calibration table is set, the coupling screw thread of securing member is set in chuck inner side, there are fixed and movable two kinds with the securing member that mates the common use of screw thread, retaining thread or other convenient process portion of fixing and dismantling fixture are set in chuck card, retaining thread, securing member, calibration table and datum line position can be manufactured separately, also can multinomially manufacture, the chuck of the present invention's design has following five technical essentials:
1: it is all that 5 degree or 10 degree have an obvious rectangular sign that spindle index table and chuck calibration scale are counted optimal design, and other 1 degree within 5 degree or 10 degree are billet sign, 0 degree, 90 degree, 180 degree, 270 can have remarkable sign and the differentiation of other number of degrees;
2: shaft transmission is that this datum line position becomes 90 degree with spindle centerline near the datum line position optimal design at main shaft position, the datum line position that can aim at main shaft end face outside when 0 degree of the chuck number of degrees should guarantee to install, the datum line position optimal design in chuck card is the connecting lines of 90 degree to 270 degree;
3: the coupling screw thread of securing member will guarantee not affect after securing member unloads the normal use of chuck and spindle taper hole (or straight hole), basic demand is that coupling Design of Screw Thread is at close spindle end, screw thread is less than chuck internal diameter, when fastener base installation or removal, not needing to dismantle chuck just can carry out, coupling major diameter of thread is greater than spindle bore, and coupling screw thread can not be in the scope of activities of claw;
4: fixed securing member is the securing member of pedestal and connecting rod one, this design interchangeability is poor, movable securing member refers to the securing member that pedestal separates with connecting rod, optimal design is that connecting rod is by afterbody, shaft and fastening nut composition, afterbody is less than spindle taper hole and is greater than fastener base aperture, shaft front end is screw rod, rear end part is hexagon (or other not revolvable shapes), pedestal has corresponding hexagon ring (or other not revolvable shapes), is easy for installation and removal like this;
5: the retaining thread optimal design of chuck card is the mid portion at two claws, two retaining threads of general design are convenient fixing, standing screw can be locked other accessory parts, generally exposing can be lower than the length of a centimetre, and positioning screw prevents that workpiece from skidding, exposed parts can be very short.
Most of multiple threads are all between 2 to 4, when turning is well wherein 1 time, only the chuck position number of degrees need to be made zero, workpiece is fixed, unclamp claw, forward the suitable number of degrees to, then clamp, just turning can be continued, and need to process axial workpiece of keyway etc., while particularly batch production in batches, if keyway is processed in subsequent handling, workpiece is difficult in the situation of clamping, can bore suitable hole at the position of processing keyway, utilize the cooperation of retaining thread and some other assembly, be easy to utilize location, hole, the flange that some are porose or plate-like workpiece or have projection or recess, also can utilize retaining thread auxiliary positioning.
