Abstract

The utility model discloses a rotary workbench for a numerical control machine tool. The rotary workbench comprises a motor, a power output end, and a cycloid and a rolling body which are mutually engaged, wherein the motor drives the cycloid or the rolling body, and the power output end is connected with the rolling body or the cycloid. The power output end is provided with and drives an automatic or manual clamp suitable for clamping a machined workpiece. The rotary workbench has the advantages that the conventional worm wheel and worm transmission is replaced by a cycloid and rolling body transmission mode, meanwhile, the rotary workbench has many engaged teeth and high structural rigidity, and the rotary workbench has high transmission precision because the cycloid and the rolling body are in zero clearance rolling.

Description

The rotary table that a kind of Digit Control Machine Tool is used

Technical field

The utility model relates to the Digit Control Machine Tool parts, especially relates to the rotary table that uses on a kind of Digit Control Machine Tool.

Background technology

Mostly the rotary table that uses on the Digit Control Machine Tool at present is the worm and gear transmission, and promptly drive motors drives the worm screw rotation, drives the worm gear motion through gear teeth meshing.Because in transmission process, synchronization has only the minority gear teeth to be meshing with each other, its rigidity is relatively poor, and in the engaged transmission process, needs between worm gear and the worm screw to slide each other, has fit clearance, causes its transmission accuracy low.

Summary of the invention

The purpose of the utility model provide a kind of rigidity height and transmission accuracy accurately Digit Control Machine Tool use rotary table.

The technical solution of the utility model is: a kind of Digit Control Machine Tool is used rotary table; Comprise motor and clutch end; It also is provided with intermeshing cycloid and rolling element, wherein said motor-driven cycloid or rolling element, and said clutch end connects rolling element or cycloid.

Motor is used for outputting power, and clutch end drives the anchor clamps of the automatic or manual that is fit to the clamping workpiece to be machined.Be the motion of rolling zero clearance between cycloid and the rolling element, and, the engagement of a plurality of cycloid tooths and rolling element arranged, thereby make overall construction intensity and rigidity increase, use under the high pulling torque condition when being specially adapted to high-rate cutting in same moment.

Said rolling element is cylinder, cydariform or spherical rolling element.Can select existing different shape rolling element for use, increase the adaptability of device.

The utility model has the advantages that: use the kind of drive of cycloid and rolling element, substituted traditional worm and gear transmission, total number of teeth in engagement is high simultaneously, and the rigidity of structure is good, rolls for the zero clearance between cycloid and the rolling element, and transmission accuracy height and precision stability are good.

The specific embodiment

Embodiment:

Consult Fig. 1 and 2, a kind of Digit Control Machine Tool is used rotary table, comprises cycloid 1, rolling element 2, motor 3 and clutch end 4, is connected on the Digit Control Machine Tool stand through fixed mount 5.Cycloid 1 is driven by motor 3, does eccentric rotary, and rolling element 2 connects clutch end 4, and is set in outside the cycloid 1, and with cycloid 1 engagement, the back of slowing down is through clutch end 4 outputs.Clutch end 4 other ends are in order to be provided with and to drive the anchor clamps of the automatic or manual that is fit to the clamping workpiece to be machined.

Consult Fig. 2; When cycloid 1 is driven rotation by motor 3; The engagement of half the cycloid tooth and rolling element was all arranged under arbitrary moment, and this just makes this Digit Control Machine Tool increase with the overall structure rigidity of rotary table, and in motion process; Rolling element and cycloid are the rolling movement of zero clearance, so its nominal torque and peak torque all are far longer than the rotary table of traditional worm and gear transmission.

In the present embodiment; Cycloid 1 is driven by motor 3; Clutch end 4 connects rolling element 2, also can drive rolling element 2 by motor 3, and clutch end 4 connects cycloid 1; The engagement that can realize cycloid and rolling element is equally slowed down, and after slowing down, passes through the anchor clamps that the automatic or manual that is fit to the clamping workpiece to be machined was exported and driven to clutch end 4.

In the present embodiment, rolling element 2 is cylindrical roller, also can be ellipsoid or spherical rolling element.

Above-listed detailed description is specifying to one of the utility model possible embodiments; This embodiment is not the claim in order to restriction the utility model; Allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.

Claims

1. the rotary table that Digit Control Machine Tool is used comprises motor and clutch end, it is characterized in that: it also is provided with intermeshing cycloid and rolling element, wherein said motor-driven cycloid or rolling element, and said clutch end connects rolling element or cycloid.

2. the rotary table of using according to the said a kind of Digit Control Machine Tool of claim 1 is characterized in that: said rolling element is cylinder, cydariform or spherical rolling element.
