Description
Technical field
The utility model relates to a kind of lathe with interior collet expander.
Background technology
At present, existing lathe is when being processed with the single products of endoporus, and because not designing special frock, causing cannot processing excircles.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of lathe with interior collet expander, simple in structure, manufacture easy to install, can converted products cylindrical.
For solving the problems of the technologies described above, the technical solution of the utility model is:
With a lathe for interior collet expander, comprise main shaft, sheath, pull bar, described sheath is coated on main shaft, and described pull bar is positioned at main shaft,
Described lathe also comprises interior collet expander, strut, adapter sleeve,
Described interior collet expander is connected in sheath and is positioned at the outside of sheath, described interior collet expander hollow, and its head offers cross recess and is interior taper,
Described strut passes and is fixed on the inside of interior collet expander, and the head of described strut is outer taper, and the external taper of the head of described strut is consistent with the internal taper of the head of interior collet expander, and the end of described strut is connected in pull bar by adapter sleeve.
Further, being connected between interior collet expander described in the utility model and sheath is threaded.
During work, according to external diameter and the length of collet expander in the internal diameter of product endoporus, Depth determination, interior collet expander is connected on sheath, sheath is connected on the main shaft of equipment, strut is put into collet expander, the pull bar of lathe and strut are linked together with adapter sleeve, product is enclosed within on interior collet expander, tension pull bar makes the head of strut by the endoporus strut of product, and the product that so just can be fixedly clamped is so that processing excircles.
Therefore compared with prior art, the utility model has following beneficial effect:
Simple in structure, manufacture easy to installly, solved the problem of product vehicle cylindrical.
