Abstract
The utility model discloses a lathe clamp, which is suitable for machining inner holes at two ends, which have high coaxiality requirements, and aims to solve the problems that the production efficiency of the process is low, and the production requirement cannot be met because a workpiece is required to be straightened and clamped for multiple times in the conventional machining process. The lathe lamp is characterized by consisting of a compaction sleeve, a spring chuck, a back-pressing pad, a mandrel, a conical sleeve and nuts, wherein eight openings which are uniformly distributed along the circumference are formed on the outer circle of the spring chuck; one end of the mandrel is connected with the inner cone of the spring chuck; the end face of the back-pressing pad is connected with the end face of the spring chuck; the compaction sleeve, the spring chuck, the back-pressing pad and the mandrel are connected with one another through the nuts to form a whole; the other end of the mandrel is connected with the inner cone of the conical sleeve; and the conical sleeve is connected with a Morse inner conical hole of a main shaft of a lathe to form a whole and fixed on the main shaft. During use, the two nuts are screwed up, so that the end face of the compaction sleeve and the end face of a sub opening of the back-pressing pad tension the spring chuck, and then the workpieces are machined. The lathe clamp has a simple structure and long service life, is convenient to operate and can meet the production requirement.
Description
Technical field
The utility model is applicable to the processing that the two ends endoporus has high axiality to require.
Background technology
Existing processing technology needs workpiece is carried out repeatedly centering and clamping, and this explained hereafter efficient is low can not to satisfy production requirement.
The utility model content
The utility model is to overcome above-mentioned deficiency, has designed a kind of turning attachment according to the processing request of workpiece.
The utility model adopts following technical scheme: a kind of turning attachment by clamping sleeve, collet, push back pad, axle, tapered sleeve, nut and form.All there are 60 ° of centre bores at the two ends that it is characterized in that axle; The cylindrical of collet has eight along the equally distributed opening of circumference; One end of axle and the inner cone of collet circle is connected, and the end face that pushes back pad is connected with the end face of collet, clamping sleeve, collet, push back pad, axle connects as one through nut; The other end of axle is connected with the inner cone of tapered sleeve circle, and tapered sleeve and lathe spindle Mohs internal taper hole connect as one and be fixed on the main shaft.With the cylindrical of workpiece inner hole sleeve, can process after tightening two nuts end face that makes clamping sleeve and the rim of the mouth end face tensioner collet that pushes back pad during use at collet.
The beneficial effect of the utility model: simple in structure, long service life easy to operately can satisfy production requirement.

The specific embodiment
As shown in the figure, tapered sleeve is connected with lathe spindle Mohs internal taper hole, and the cylindrical of collet has eight along the equally distributed opening of circumference, and an end of axle is connected with the inner cone of collet circle, and the end face that pushes back pad is connected with the end face of collet.
Operation principle:
Tapered sleeve and lathe spindle Mohs internal taper hole connect as one and are fixed on the main shaft, with the cylindrical of workpiece inner hole sleeve at collet, can process after tightening two nuts end face that makes clamping sleeve and the rim of the mouth end face tensioner collet that pushes back pad during use.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
