Abstract

The invention provides a numerically-controlled vertical rotary working table. The numerically-controlled vertical rotary working table comprises a tool body; a servo motor which is arranged on the tool body is connected with a gear reducer through screws; the gear reducer is connected with a gear; a worm is fixedly arranged on a gear which is meshed with the gear; the worm is meshed with a worm gear; an inner hole of the tool body is provided with a main shaft; the working table is fixedly arranged at one end of the main shaft; the worm gear is fixedly arranged on the main shaft; a ball bearing is arranged on one side of the worm gear and between the mains shaft and the tool body; a transition sleeve is fixedly arranged on the other side of worm gear of the tool body; a combined bearing is arranged between the main shaft and the transition sleeve; the tool body is provided with a braking oil cylinder and a braking cover; a piston is arranged in the braking oil cylinder; the end portion of the piston is provided with a braking piece which is in contact with the braking cover. According to the numerically-controlled vertical rotary working table, the bilateral sides of a worm gear pair are supported by the bearings and accordingly abrasion of the worm gear pair is greatly reduced and the bearing capability is improved and eight small piston oil cylinders are utilized to lock the rear end of the mains shaft of the rotary table tightly and accordingly enough locking force can be provided and the product cost is reduced.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a high-division and heavy-loading numerical control vertical rotary workbench. Background technique [0002] The CNC vertical rotary table is an ideal accessory for various CNC boring and milling machines and machining centers. The main shaft is installed horizontally on the working table of the main machine, and the rotary table can complete various indexing and rotary work under the control of the relevant control system of the main machine. The mechanical accuracy of the existing CNC vertical rotary table is mainly guaranteed by adding an angle encoder to the worm gear pair or the main shaft, but when it is subjected to heavy loads, its accuracy cannot be guaranteed. At the same time, the worm gear pair wears quickly and the product life is short. The overall large piston is used for locking, and the locking effect is poor and the cost is high.
