Novel simple vertical lathe worktable spindle structure

Abstract

The invention discloses a novel simple vertical lathe worktable spindle structure. The novel simple vertical lathe worktable spindle structure comprises a base, a center shaft which is vertically upwards is arranged in the middle of the base, the center shaft penetrates through the base, the top of the center shaft is higher than the top of the base, multiple end face sliding bearing guide rail blocks are arranged on the top face of the base in the circumferential direction, a worktable is arranged on the upper portion of the end face sliding bearing guide rail blocks, the part, exceeding thetop face of the base, of the center shaft is in a circular truncated cone shape, the outer side of the top of the center shaft is provided with a radial sliding bearing conical sleeve, the radial sliding bearing conical sleeve is a conical sleeve which is through up and down, the taper of the conical sleeve is matched with the top taper of the center shaft, a center bearing cover is arranged on the top of the center shaft, an adjusting gasket with the height capable of being adjusted is arranged between the center bearing cover and an inner sleeve, and a rotating table is fixedly mounted on the upper portion of the worktable. The structure has the beneficial effects that the cost is lower than that of an existing vertical lathe worktable, and maintaining and debugging are convenient.

Description

technical field [0001] The invention belongs to the technical field of vertical lathes, and in particular relates to a novel simple vertical lathe workbench spindle structure. Background technique [0002] Vertical lathes are indispensable equipment in heavy machinery manufacturing, and can be used to process larger rotary parts. Because traditional vertical lathes use end bearings to bear axial forces, the size of end bearings is larger, which greatly increases vertical lathes. The price of the type lathe, for the small and medium-sized enterprises that have just started, directly purchasing the equipment will undoubtedly increase the burden on the enterprise. [0003] The present invention designs a new type of simple vertical lathe workbench spindle structure, which mainly bears the axial force and radial force during processing through two sliding bearings, avoiding the shortcomings of traditional vertical lathes and reducing costs. Contents of the invention [0004] ...
