Description
Technical field
The utility model relates to a kind of machined positioner, is specifically related to a kind of lathe and adds man-hour for the device of axial location.
Background technology
In conventional art, while utilizing lathe working shaft-like workpiece, be generally, with scroll chuck, workpiece is carried out to fastening clamp.The front end of lathe spindle has a taper hole, on the front end face of taper hole, by terminal pad, is installed with scroll chuck, between lathe spindle, terminal pad, scroll chuck, will keep very high axiality, to guarantee machining accuracy.
When some axial dimensions of processing have the shaft-like workpiece of required precision, need to carry out axial location to workpiece, general way is positioning step of sidecar system in the claw of scroll chuck, during clamping workpiece, workpiece end face is held out against and on positioning step, realize axial location.For the workpiece of different batches, different size, need the positioning step size of car system also different, often change a kind of size car one-time positioning step processed again, this method of operating is very dumb, and the amount of labour is large.And, when scroll chuck car will cause claw thickness too little after several times, cause claw to be scrapped, therefore such way is in fact very uneconomical.
Utility model content
The utility model technical issues that need to address are to provide a kind of axial direction positioning device for lathe processing, to overcome traditional localization method very flexible, workload is large, chuck loss is large shortcoming.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
Axial direction positioning device for lathe processing, comprise the adapter sleeve being installed in lathe spindle taper hole, adapter sleeve is offered endoporus along axle center, the endoporus of adapter sleeve is threaded connection the positioning screw that lathe spindle outside is stretched out in end, the excircle that positioning screw stretches out adapter sleeve one side coordinates installation clamp nut, described positioning screw stretches out the end of adapter sleeve one side termination, location is installed, and the outer face of termination, described location is perpendicular to the central axis of positioning screw.
Further improvement of the utility model is: termination, described location is connected with positioning screw by a mounting head, the end that described positioning screw stretches out adapter sleeve one side is coaxially provided with externally threaded cylindrical mounting head, the diameter of described mounting head is less than the diameter of positioning screw, and the link of termination, described location and mounting head arranges the female blind hole of being with of Matching installation head.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is as follows:
The utility model is simple in structure, be convenient to fabrication and installation, by termination, location is set at lathe spindle front end, can provide for shaft-like workpiece to be processed a reliable datum level, avoid workpiece beating in process, can improve the machining accuracy of axial dimension.Owing to being threaded connection between positioning screw and adapter sleeve, positioning screw stretches out the length of adapter sleeve part can be adjusted flexibly, and then can adjust the position of termination, location, compares with the positioning step processed of getting on the bus at scroll chuck, time saving and energy saving, and can not shorten life-span of scroll chuck.Owing to being dismountable being threaded between location termination and positioning screw, can select the suitable termination, location of size according to the diameter of workpiece to be processed, it is convenient to change, and working (machining) efficiency is high.
In the utility model, the end of positioning screw is also provided with mounting head, and the diameter of mounting head is less than the diameter of positioning screw, when installing and changing termination, location, and can be more convenient.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model.
Wherein: 1. adapter sleeve, 2. positioning screw, 21. mounting heads, 3. clamp nut, 4. termination, location.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done further to describe in detail:
Axial direction positioning device for lathe processing, as shown in Figure 1, comprises adapter sleeve 1, positioning screw 2, clamp nut 3 and termination 4, location.
Adapter sleeve 1 is a tapered sleeve, and the taper hole of the profile of tapered sleeve and lathe spindle front end matches, and tapered sleeve is offered endoporus along axis, is provided with the internal thread matching with positioning screw 2 in the endoporus of tapered sleeve.During installation, one end that adapter sleeve 1 diameter is less is installed in lathe spindle taper hole, and positioning screw 2 is installed in the endoporus of one end that diameter is larger.
One end of positioning screw 2 is installed in the endoporus of adapter sleeve 1, and the other end stretches out adapter sleeve away from a side of lathe spindle.
Clamp nut 3 is arranged on by threaded engagement on the excircle of positioning screw 2, the outer face that the rear clamp nut 3 in location is close to adapter sleeve 1 larger one end of diameter is installed, for fastening positioning screw 2.
In the present embodiment, the end that positioning screw 2 stretches out adapter sleeve one side is provided with the columniform mounting head 21 coaxial with positioning screw 2, mounting head 21 diameter be less than the diameter of positioning screw, and its excircle is provided with external screw thread.Termination 4, location is arranged in mounting head 21.Termination 4, location is provided with blind hole with one end that mounting head 21 is connected, and is provided with the internal thread mating with the external screw thread of mounting head 21 in blind hole.Termination, location is the central axis perpendicular to positioning screw 2 away from the end face of a side of backstay screw rod 2, with thinking that workpiece to be processed provides axial plane of orientation.
The setting of mounting head 21 just, for the ease of changing termination 4, location, is in fact located termination 4 and also can be directly installed to the end of positioning screw 2, only the blind hole of termination 4, location need to be arranged to the size matching with positioning screw 2.
After above-mentioned parts are installed on lathe, then terminal pad and scroll chuck are installed, termination 4, location is among the through hole of scroll chuck inside.While using the utility model to carry out Machining of Shaft-type Parts, by a flat end face of shaft-like workpiece being pressed on the end face of termination 4, location, with scroll chuck, shaft-like workpiece is fixed again, finally used another end face of the tailstock top tight workpiece of lathe, can realize the axial location of workpiece.Because two end faces of shaft-like workpiece are all secured in a press, so in process, the axial runout of shaft-like workpiece is little, while processing same workpiece, without tool setting repeatedly, can significantly improve machining accuracy and efficiency.By the length that regulates positioning screw to stretch out adapter sleeve, can adjust the axial location of termination 4, location, to adapt to the shaft-like workpiece processing of different size, without car positioning step processed repeatedly on scroll chuck, reduced chuck loss, time saving and energy saving.Due between location termination 4 and positioning screw 2 for being threaded, when shaft-like workpiece diameter difference to be processed, can dismantle easily and change the termination, location of different size.
