Description

Milling machine capable of continuous machining of circular inner holes

technical field

The utility model relates to a milling machine, in particular to a milling machine capable of continuously processing circular inner holes, and belongs to the technical field of mechanical equipment.

Background technique

A milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece (and) the milling cutter is the feed movement. Milling machines are also more efficient than planers and are widely used in machinery manufacturing and repair departments. However, the existing milling machines generally can only process planes, grooves, and corresponding inner holes according to the milling cutter, but the same milling machine cannot rapidly and continuously process parts with circular holes in cross section.

Utility model content

The purpose of the utility model is to solve the above problems, and propose a milling machine capable of continuously processing circular inner holes.

The purpose of this utility model is achieved through the following technical solutions:

A milling machine capable of continuously processing circular inner holes includes a bed, a milling cutter assembly placed above the bed, a guide rail is fixed on the bed, and the milling machine also includes a rotary table placed below the milling cutter assembly, a drive unit The motor for turning the turntable is described. The turntable includes a rotating table with a circular cross section. A rotating shaft is connected to the bottom of the rotating table. The rotating shaft is placed on a bearing seat through a bearing. The rotation of the rotating table The shaft is connected with the motor through a pulley, and the motor drives the rotating table to rotate.

Preferably, the rotating table is parallel to and not coaxial with the milling cutter axis of the milling cutter assembly.

Preferably, the bottom of the bearing seat is provided with a base for connecting with a guide rail, and the base is screwed to both sides of the guide rail.

Preferably, the motor is fixedly connected to the fuselage through a frame.

The beneficial effects of the utility model are mainly reflected in that: by setting the rotary table, the workpiece with a circular inner hole can be directly processed on the same milling machine, the processing efficiency is high, and the cost is correspondingly reduced.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

detailed description

The utility model discloses a milling machine capable of continuously processing circular inner holes, which is the same as the prior art, including a bed and a milling cutter assembly placed above the bed, and a guide rail 6 is fixed on the bed. Since the milling cutter assembly is the same as the prior art and is not the technical focus of this application, it will not be repeated here.

As shown in Figures 1-2, different from the prior art, the milling machine also includes a turntable placed below the milling cutter assembly, a motor 5 that drives the turntable to rotate, and the turntable includes a section It is a circular rotating table 1, the bottom of which is connected with a rotating shaft 2, the rotating shaft 2 is placed on the bearing seat 3 through a bearing, and the rotating shaft 2 of the rotating table 1 is connected with the said rotating table 1 through a pulley 51 The motor 5 is connected, and the motor 5 drives the rotating table 1 to rotate. The bottom of the bearing seat 3 is provided with a base 4 for connecting the guide rail 6, and the base 4 is provided with threaded holes 41, which can be connected to both sides of the guide rail 6 by bolts. The motor 5 is fixedly connected with the fuselage through a frame. A number of holes 11 are provided on the rotating table, and the scraps on the milling machine fall directly from the holes.

Since the workpiece to be machined generally has a circular inner hole, it is necessary to make the rotating table 1 parallel to and not coaxial with the milling cutter axis of the milling cutter assembly. Of course, it can also be used to process arc-shaped outer diameter workpieces accordingly.

Place the workpiece to be processed on the rotating table 1, start the milling machine and the motor 5, and when the motor 5 is working, it will drive the belt pulley 51 to make the rotating table start to rotate, and the milling cutter assembly can start processing. Since the rotating table is in rotation, it can automatically The product is rotated, and the required circular inner hole can be processed very quickly. If you want to process inner holes with different diameters, you only need to adjust the lateral distance between the milling cutter and the rotary table, which is convenient, quick and practical.

The utility model still has many specific implementation modes, and all technical solutions formed by equivalent replacement or equivalent transformation all fall within the protection scope of the utility model.
