Positioning spindle device for reaming and honing machine

Abstract

A positioning spindle device for a reaming and honing machine comprises spindles (35) and spindle gears (36) installed on the spindles. The positioning spindle device is characterized in that an upper end cover (351) and a lower end cover (352) are further installed at the upper end and the lower end of each spindle (35), sleeve the spindle (35) respectively through an upper bearing (353) and a lower bearing (357), and are fixed on an upper cover plate and a lower cover plate of each fixed disc (5) which is of a box-shaped structure respectively. The positioning spindle device has the advantages that the shaking of a reaming and honing cutter bar does not occur due to the structural improvement of the spindle device, the vertical operation is stable, the workpiece processing accuracy is guaranteed, and a certain production quality is improved.

Description

Technical field [0001] The invention relates to a machine tool, in particular to a reaming honing device. Background technique [0002] The reaming honing machine with a positioning spindle is a special machine for reaming and honing. At present, most of the market adopts a single type, that is, the inner hole of the workpiece to be processed is first reamed, and the reamed workpiece is taken to another honing machine for inner hole honing Because the workpieces are made of stainless steel, iron or copper, a batch of workpieces is very heavy to be transported in a centralized manner. Forklifts are required, which is time-consuming and labor-intensive, and both the reaming machine and honing require a special person to guard. Can honing a part, resulting in particularly low work efficiency. [0003] The existing solutions all use the tooling tool to be directly installed on the positioning spindle, which is unstable when the spindle rotates, which is prone to jitter of the tool bar...

Problems solved by technology

[0002] The reaming honing machine with positioning spindle is a special machine tool for reaming and honing. At present, most of the market adopts a single type, that is, the inner hole of the workpiece to be processed is reamed first, and the reamed workpiece is taken to another honing machine for inner hole honing. , since the workpieces are all made of stainless steel, iron or copper, a batch of workpieces is quite heavy to carry in a centralized manner, requiring the use of a forklift, which is time-consuming and laborious, and both the reaming machine and the honing require a special person to guard, and only one part can be reamed at a time or only one part can be reamed at a time. One part can be honed, resulting in particularly low work efficiency

[0003] The existing solutions are to directly install the tooling tool on the positioning spindle. The spindle is not stable when it rotates, and it is easy to cause the tool bar to shake, the stability is poor, and the precision of the workpiece processing is reduced.
