Abstract

The utility model provides a flexible non-self-centering double-end clamping main shaft which comprises a box body, wherein a main shaft, a belt pulley, a bearing in a back-to-back structure, a flexible chuck, a self-centering spring chuck and a spring clamp seat are arranged in the box body; the right end of the main shaft is provided with a flexible chuck and a right cover, and the flexible chuck clamps the regular parts; the left end of the main shaft is provided with a self-centering spring chuck, a spring chuck seat and a left cover, wherein the self-centering clamp and a right chuck finish the clamping work of parts together. The utility model has better clamping adaptability, so the coaxial processing purpose is achieved under the drive of the rotating main shaft for the position requirement of irregular wool and special-shaped clamping, and the application field is very wide.

Description

Flexible non-self-centering double-end clamping main shaft

Technical Field

The utility model relates to the field of metal cutting, in particular to a flexible non-self-centering double-end clamping main shaft which is used for clamping a part, rotating and then cutting.

Background

At present, in metal cutting machining, a part with an irregular coaxial clamping surface cannot be coaxially clamped, only one end of the part can be clamped, an outer circle and an inner hole of the other end of the part are machined, and the other end of the part is positioned and machined by a preorder hole.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art, provides a flexible non-self-centering double-end clamping main shaft, has better clamping adaptability, meets the requirements on positions of irregular blanks and special-shaped clamping, achieves the aim of coaxial processing under the driving of a rotating main shaft, and has very wide application field.

The self-centering spring chuck comprises a box body, wherein a main shaft, a belt pulley, a bearing in a back-to-back structure, a flexible chuck, a self-centering spring chuck and a spring clamp seat are arranged in the box body; the right end of the main shaft is provided with a flexible chuck and a right cover, and the flexible chuck clamps the regular parts; the left end of the main shaft is provided with a self-centering spring chuck, a spring chuck seat and a left cover, wherein the self-centering clamp and a right chuck finish the clamping work of parts together. The left cover and the right cover play a role in sealing dust prevention and water drainage.

In a further improvement, the belt pulley is provided with a power hole system. The power hole adopts an oil pressure source or an air pressure source.

In a further improvement, the main shaft drives the self-centering spring chuck and the spring chuck seat to complete the clamping work of parts through an oil distribution ring or an air distribution ring.

The utility model has the beneficial effects that:

1. the dough is not required to be prepared for processing, and the processing efficiency is improved.

2. The surface adjusting processing has clamping errors, and the coaxial precision without one-time clamping processing is high and the quality is stable and reliable. The processing result is twice as good as the result with half the effort.

3. Under the condition of the same power source, the energy consumption of the two ends of the power source is greatly reduced by processing the two ends simultaneously, and the operation performance of the power source does not need to be adjusted manually.

4. The reduction is scrapped, and its cutting performance also brings stable cutting effect because of both ends centre gripping, and its rotational speed, cutting output improve by a wide margin to accomplish utility model's purpose.

5. The manual work is not counted at the same two ends of the processing efficiency, and the processing time is only counted and shortened by one time.
