Problems solved by technology

The existing CNC rotary table has complex structure, high cost, and difficult maintenance and adjustment. At the same time, the table is only supported by bearings. The supporting bearing capacity of such bearings in the axial and radial directions is limited, resulting in the movement accuracy of the table. And the application status of carrying capacity is not ideal

Embodiment Construction

[0030] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0031] Such as figure 1 and figure 2 As shown, a CNC rotary table for laser processing includes a table base 1, a table 2 arranged on the table base, a rotating shaft 3, a support ring 7, a plurality of support balls 8 and a plurality of needle rollers 9. The inside of the rotating shaft is provided with a through hole, and the rotating shaft rotates under the action of the driving mechanism. The driving mechanism includes a driving motor, a worm 5 and a worm wheel 4, and the worm wheel is installed on the rotating shaft. The worm is rotatably mounted on the base of the workbench, one end of the worm is connected to the output shaft of the drive motor, and the other end is engaged with the worm wheel;

[0032] The base of the worktable is provided...

Abstract

The invention discloses a numerical control rotary workbench for laser processing. The numerical control rotary workbench comprises a workbench base, a workbench body, a rotary shaft, a supporting ring, a plurality of supporting balls and roller pins, the supporting ring is installed on the workbench base, a needle roller thrust bearing is arranged between the supporting ring and the workbench body, the rotary shaft extends out of a supporting table upwards, and the supporting table is connected with the workbench body upwards. The supporting table is connected with a turbine downwards and provided with first positioning steps for installing the roller pins and second positioning steps for installing the supporting balls, the roller pins are arranged on the inner side of the supporting ring, and the supporting balls are arranged at the bottom of the supporting ring. According to the numerical control rotary workbench for laser processing, the needle roller thrust bearing bears axial force, the supporting balls arranged in the annular mode are mainly stressed in the axial direction, stable axial supporting on the workbench is achieved, the roller pins can achieve radial constraint on the rotary shaft, the supporting ring and the workbench base, the structure is simple and compact, machining and assembling are convenient, the cost is low, maintenance is convenient, and the axialand radial bearing capacities of the rotary workbench are improved.

Description

technical field [0001] The invention relates to a numerically controlled rotary worktable for laser processing, belonging to the technical field of numerically controlled machine tool components. Background technique [0002] CNC rotary table is an indispensable functional part of CNC boring and milling machine, gantry machining center, CNC gear milling machine, gear grinding machine, etc. It is installed on a rotary multi-station machine tool to realize the multi-process processing of parts at one time. It is a kind of workbench, which can carry out numerical control indexing to the workpiece under the drive of the related system or link with the machine tool to continuously rotate the workpiece. [0003] The corner accuracy and surface roughness of the existing processed parts have high requirements on the machine tool and the CNC rotary table, while the movement accuracy, bearing capacity, and ability to deal with impact of the CNC rotary table are related to the entire m...
