Summary of the invention
The purpose of this utility model is to provide one to meet Automatic-feeding equipment completely, and tell material effective, failure rate is low, alleviates labor strength, saves the spindle of numerical control lathe automatic material blanking mechanism of processing cost.
The mechanism that the collet interior of the utility model mainly existing spindle of numerical control lathe is set up, concrete technical scheme is as follows:
The utility model mainly includes central siphon, chuck, push rod, stop collar, stop nut, spring and stop screw, the front end of its central siphon is threaded connection chuck, the push rod coaxial with it established by central siphon, the front end of this push rod is stretched in the centre bore of chuck, described push rod is socketed stop collar, and the back-up ring of this stop collar and central siphon inside is together by a threaded connection, above-mentioned push rod is established the stop nut be threaded with it, one end of stop nut be enclosed within spring one end on push rod and connect, the other end of spring connects with the circular groove bottom land near central siphon rear end, the rear end of above-mentioned push rod has the stop screw be threaded with it, and this spacing screw thread stretches into spring inner and connects with push rod, the utility model also includes footstock, little push rod and stage clip, axial screw is inwardly offered along described push rod front end, rearward end and the screw of described footstock pass through threaded engagement, described footstock has the step through-hole axially offered along it, the leading portion bore dia of this step through-hole is greater than back segment bore dia, the little push rod coaxial with it is established in described step through-hole, this little push rod is step bars, its leading portion shank diameter is less than stage casing shank diameter, its back segment shank diameter is also less than stage casing shank diameter, and the leading portion shank diameter of little push rod is less than or equal to the leading portion bore dia of step through-hole, the stage casing shank diameter of little push rod is less than or equal to the back segment bore dia of step through-hole, the end top, front end of described little push rod is stretched out by the front end of step through-hole and towards the workpiece hole of chuck, the back segment bar of above-mentioned little push rod is socketed stage clip, and the front end of this stage clip connects with the stage casing rod rear end of little push rod, and the other end of spring connects with at the bottom of the screw hole of above-mentioned push rod inside.
The front end of described push rod is provided with the stop nut be threaded with footstock, more firm to ensure the position of footstock.
Operationally, workpiece is entered by the workpiece hole of chuck the utility model, withstands on the front end of little push rod after entering, promote little push rod to move backward, make stage clip be compressive state, chuck realizes the clamping to workpiece, starts to process workpiece, after machining, chuck removes clamping, now, and stage clip return, the workpiece automatic spring that little push rod will process, realizes automatic blanking.
The present invention/utility model compared with prior art tool has the following advantages:
1, in process, there will not be the phenomenon of two workpiece collisions, do not damage lathe, the fault rate of Tu Liao mechanism reduces greatly;
2, automatically tell material effective, blanking accuracy rate is high, alleviates labor strength, saves processing cost;
3, structure, technique are simply, simple to operate, are convenient to maintenance, long service life.
