Abstract
The utility model discloses a positioning mandrel, which comprises a mandrel and positioning bolts, wherein the middle of the mandrel is provided with a counter bore. The positioning mandrel is characterized in that an annular step is arranged on the outer wall of an opening of the counter bore of the mandrel and provided with a plurality of positioning holes, and one bolt is screwed into each positioning hole and extends into the counter bore. The head of the mandrel is provided with the positioning holes, the positioning bolts are mounted in the positioning holes, a workpiece can be stably mounted on the inner wall of the positioning mandrel by a compression method through the bolts, stability of processing quality is improved, clamping is convenient, and production efficiency is increased. The positioning mandrel is wide in applicable range, free of sliding friction and long in service life.
Description
Technical field
The utility model relates to a kind of positioning core axle.
Background technology
When the processing ring parts, when needs endoporus and datum level location, and when the form and position tolerance at processing place and place, location is higher, just must adopt reliable locate mode, need guarantee that when clamping center, practical work piece hole is consistent with the work table rotation center, defectives such as the while also will be guaranteed the axial location unanimity, exists difficulty of processing big in the existing technology, and working (machining) efficiency is low.
The utility model content
The utility model provides a kind of positioning accuracy height at the problems referred to above, is applicable to the positioning core axle of batch process.
The utility model technical solution problem provides following scheme:
Positioning core axle, have the mandrel and the bolt of counterbore in the middle of comprising, it is characterized in that: the oral area outer wall of described mandrel counterbore has ring-shaped step, offers several locating holes on the described ring-shaped step, be combined with bolt in the described locating hole, described bolt extend in the described counterbore.
The utility model has been offered several locating holes on the spindle nose of mandrel, bolt is installed in locating hole, adopt the method that compresses of bolt to make stable being installed on the positioning core axle inwall of workpiece energy, improved the temperature of crudy, and the clamping facility has improved production efficiency, the utility model is applied widely, fricton-tight friction, long service life.
