Description

Boring machine for deep hole machining

Technical Field

The utility model relates to a boring machine for BTA belongs to machining equipment technical field.

Background

Because the boring bar and the square ram of the large numerical control floor type boring and milling machine tool are high in mass and in a suspension state, the larger the working stroke is, the larger the maximum overhang amount is, and the ram inevitably generates distortion deformation in the extending process due to weight factors of accessories such as the ram and a main shaft thereof, so that the angle error and the displacement error of the main shaft and a cutter of the machine tool are caused, and the machining precision of the machine tool is influenced. When two center holes with a long distance are machined, the extending length of the ram is not enough, the traditional technological method is to machine the center hole at one end, rotate the workbench for 180 degrees, and then machine the center hole at the other end, so that the higher concentricity requirement of the two center holes is difficult to guarantee.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the problem that exists, a can realize the disposable processing of two remote centre bores is provided, and can guarantee the high accuracy deep hole boring machine for BTA of higher concentricity requirement.

The utility model discloses a realize through following technical scheme:

the boring machine for deep hole machining comprises a machine body and a ram, wherein two guide rails are arranged on the machine body, a sliding plate is arranged on the guide rails, two ram supports are arranged on the sliding plate, the ram is arranged between the interiors of the two ram supports, the lower ends of the ram supports are fixedly connected to the sliding plate, and a facing head is arranged at the front end of the ram.

Use the utility model discloses can realize that a clamping accomplishes the bearing frame work piece, satisfy drawing and technological requirement, can be accurate, quick realization cutter location, reduce the increase of lathe ram because of the elongation, and arouse the increase of ram drooping volume and amount of deflection, guarantee the machining precision, can realize the disposable processing of two centre bores far away, and guaranteed higher concentricity requirement.

The utility model discloses a further improvement still, install the feed motor on the lathe bed, the feed motor passes through the vice drive slide of ball screw and moves along the guide rail.

The utility model discloses a further improvement still, two ram support mountings are on the both ends of slide.

The utility model discloses a further improvement still, install spindle motor on the ram, spindle motor loops through speed reducer, hold-in range, shaft coupling drive main shaft rotatory.

The utility model discloses a further improvement still, be equipped with servo motor in the facing head, servo motor passes through hold-in range, helical gear drive facing head and removes along radial direction.

The utility model discloses a further improvement still, the ram support of ram rear end and rear end is neat mutually.

Compared with the prior art, the utility model discloses the beneficial effect who has is:
