Description

Machine tool gantry and numerical control machine tool

Technical Field

The utility model relates to the technical field of machining equipment, in particular to a machine tool gantry and a numerical control machine tool.

Background

The gantry is an important part of a gantry machine tool, and the stability of the gantry directly influences the stability of the whole machine. Stability is one of important performance indexes of a machine tool, because in the long-term working process of the machine tool, if the machine tool resonates, bends and deforms and the like, adverse effects of precision reduction are caused to the whole equipment, and the adverse effects are mainly represented by gap change at the joint of a gantry beam and an upright post and deformation of a wire rail and an installation part of the wire rail. For this, a solution is needed.

Disclosure of Invention

The utility model provides a machine tool gantry which comprises a cross beam and upright posts arranged at two ends of the cross beam, wherein the cross beam and the upright posts are integrally formed; the beam is provided with two line rail installation parts, and the arc transition is arranged between the two line rail installation parts.

The utility model is further provided with: the crossbeam is integrally provided with a motor seat and a bearing seat.

The utility model is further provided with: and a chamfer angle is arranged at the joint of the cross beam and the upright post.

The utility model is further provided with: the cross beam and the upright post are provided with lightening holes.

The utility model is further provided with: the upright posts and the non-processing surfaces on the cross beams adopt concave table structures.

A numerically controlled machine tool comprising a machine tool body and a machine tool gantry as described above disposed on the machine tool body.

The beneficial effects of the utility model are as follows:

through with crossbeam and stand integrated into one piece, improve the wholeness of longmen. The arc transition treatment is carried out between the wire rail mounting parts, so that the deformation resistance of the wire rail mounting parts is improved.

Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Example 1

The embodiment provides a machine tool gantry, which comprises a cross beam 1 and upright posts 2 arranged at two ends of the cross beam 1. The upright post 2 and the cross beam 1 are integrally cast, so that a mounting surface is not arranged between the upright post 2 and the cross beam 1, and a chamfer angle 6 is arranged at the joint of the cross beam 1 and the upright post 2, so that the strength of the joint of the cross beam 1 and the upright post 2 is improved, and the integration of the gantry is better.

The cross beam 1 is internally provided with a rice-shaped rib 7 which is communicated and arranged along the length direction so as to reduce weight and improve rigidity of the cross beam 1. The beam 1 is also integrally provided with a wire rail mounting part 5, a motor base 3 and a bearing seat 4. The two line rail mounting portions 5 are arranged in parallel, and arc transition is carried out between the two line rail mounting portions 5, which means that corners are not arranged between the line rail mounting portions 5 and the beam 1, and the line rail mounting portions 5 are smoothly transited to the other line rail mounting portions 5, so that stress concentration positions do not exist between the line rail mounting portions 5, roots are obviously thickened, strength is improved along with the stress concentration positions, and therefore the deformation resistance is improved. The bearing seat 4 and the motor seat 3 are both arranged between the two wire rail mounting parts 5.

In addition, the side surfaces and the back surfaces of the cross beam 1 and the upright post 2 are provided with a plurality of lightening holes, and the surfaces which are not processed are all in a concave table structure, so that the processing area can be reduced, and the processing precision is ensured. The lightening holes and the recess structures are shown in the drawings, but numerous are not specifically identified.

Example 2
