Novel multi-line guide rail device of machine tool

Technical Field

The utility model relates to a digit control machine tool specifically indicates a novel multi-thread guide rail of lathe device.

Background

The numerically controlled machine tool is a basic equipment for machining workpiece, and can machine various workpieces in different shapes by changing the relative position between the cutter and the workpiece and matching the rotating speed of the selected milling cutter to make the cutter perform cutting machining on the workpiece.

The traditional numerical control machine tool is provided with two guide rails which are respectively arranged on two sides of a driving screw rod, but for a larger workpiece or a workpiece with a larger size, the bearing capacity of the guide rails is poor, the large workpiece cannot be borne, and for the workpiece with the larger size, due to two-point support of a track, the supporting surface is small, so that the deformation and the like are easily caused, so that more and more numerical control machine tools adopt a plurality of guide rails in a multi-line manner to improve the bearing capacity and increase the supporting surface to avoid the deformation of the workpiece. However, the workpiece machined by the numerical control machine tool is a metal block cut into a required workpiece, so that more metal chips can be generated and accumulated in the numerical control machine tool, particularly, the metal chips are easily accumulated between guide rails, in order to avoid the accumulation of the iron chips and difficult cleaning, the distance between the guide rails arranged at the two sides of the screw rod needs to be controlled to a certain width, otherwise, the accumulated chips are difficult to clean due to the fact that the focal length between a bearing seat connected with the screw rod and the guide rails arranged at the two sides of the bearing seat is too small, and the operation of the screw. Therefore the utility model discloses to above-mentioned current technical problem study and improve.

SUMMERY OF THE UTILITY MODEL

To the problem that above-mentioned prior art exists, the utility model provides a novel multi-thread guide rail of lathe device can effectively solve the problem that above-mentioned prior art exists.

The technical scheme of the utility model is that:

a novel multi-line guide rail device of a machine tool comprises a multi-line guide rail arranged on a base through a guide rail base, wherein the multi-line guide rail comprises a first inner side guide rail and a second inner side guide rail which are arranged on two adjacent side edges of a driving mechanism; the driving mechanism comprises a screw rod connected with a motor, at least two bearing seats used for assisting in fixing the screw rod are rotatably arranged on the screw rod, and the bearing seats are arranged between a first inner side guide rail and a second inner side guide rail in a left-right parallel mode; the bearing seats are arranged in an air way through a rack arranged between the first inner side guide rail and the second inner side guide rail; the rack comprises arc plates which are respectively and symmetrically arranged on the inner sides of the guide rail bases where the first inner side guide rail and the second inner side guide rail are located, the arc plates are arranged in a downward bending mode, and the upper surfaces of the arc plates are connected to the first inner side guide rail and the second inner side guide rail which are connected with the arc plates through corresponding reinforcing ribs; the bearing blocks are respectively and fixedly connected above the arc-shaped plates of the corresponding racks.

The multi-line guide rail also comprises at least two outer side guide rails which are respectively arranged at the outer sides of the first inner side guide rail and the second inner side guide rail.

The utility model has the advantages that:

the utility model discloses a setting up the arc that the rigid coupling has the symmetry to set up respectively at the inboard guide rail of first inboard guide rail and the second on lead screw both sides limit, two arc formation arch bridge type's frame is used for supporting bearing frame, and soaks the setting with the bearing frame, and then makes the both ends intercommunication outside of the inboard guide rail of first inboard guide rail and second, avoids leading to the little problem in intercommunication clearance because of sheltering from of traditional structure middle bearing frame, and then does benefit to the clearance of iron fillings, prevents that iron fillings from piling up and hindering the lead screw motion. And moreover, the fixing and stabilizing performance of the rack is improved by arranging the arc plates of the arch bridge type and the reinforcing ribs, and the two symmetrical arc plates are not connected, so that the effect of buffering elasticity can be achieved on the bearing seat connected with the lead screw.

Detailed Description

To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:

referring to fig. 1-2, a novel multi-line guide rail device for a machine tool comprises a multi-line guide rail arranged on a base 8 through a guide rail base 1, wherein the multi-line guide rail comprises a first inner side guide rail 2 and a second inner side guide rail 3 which are arranged on two adjacent side edges of a driving mechanism, and at least two outer side guide rails 4 which are respectively arranged on the outer side edges of the first inner side guide rail 2 and the second inner side guide rail 3; the driving mechanism comprises a screw rod 5 connected with a motor, at least two bearing blocks 6 used for assisting in fixing the screw rod 5 are rotatably arranged on the screw rod 5, and the bearing blocks 6 are arranged between the first inner side guide rail 2 and the second inner side guide rail 3 in parallel from left to right; the bearing seats 6 are arranged in an empty way through a rack arranged between the first inner side guide rail 2 and the second inner side guide rail 3; the rack comprises arc plates 7 which are respectively and symmetrically arranged on the inner sides of the guide rail bases 1 where the first inner side guide rail 2 and the second inner side guide rail 3 are arranged, the arc plates 7 are arranged in a downward bending mode, and the upper surfaces of the arc plates 7 are connected to the first inner side guide rail 2 and the second inner side guide rail 3 which are connected with the arc plates through corresponding reinforcing ribs 9; the bearing blocks 6 are respectively and fixedly connected above the arc-shaped plates 7 of the corresponding machine frame.
