Abstract

The invention discloses a servo direct connection type spindle device which comprises claws, a rotating shaft, a disc spring assembly, a first air cylinder, a second air cylinder, a sliding sleeve, apressing sleeve and a transmission device. A push rod is arranged in the rotating shaft, the claws are arranged at one end of the rotating shaft and connected with one end of the push rod, the slidingsleeve is arranged at the other end of the rotating shaft, the disc spring assembly is arranged on the push rod in a sleeving mode, the pressing sleeve is arranged at the other end of the push rod ina sleeving mode, and the sliding sleeve is connected with a positioning pin; and the first air cylinder pushes the sliding sleeve through a first piston, the second air cylinder makes contact with the positioning pin through a second piston and pushes the pressing sleeve, and the rotating shaft is connected with the transmission device through a coupler. According to the servo direct connection type spindle device, the air cylinder pushes the positioning pin to drive the pressing sleeve to move forwards, meanwhile, the push rod moves forwards, the claws are separated from the rotating shaft to achieve automatic loosening, and automatic clamping is achieved through pre-tightening force of the disc spring.

Description

technical field [0001] The invention relates to a servo direct-connection spindle device, which belongs to the technical field of mechanical processing. Background technique [0002] In the mechanical polishing and grinding industry, the spindle is the main part in the processing process. In the existing processing process, the workpiece cannot be positioned and ground synchronously with the grinding head, and the workpiece clamping is manually clamped, so the processing efficiency is low. In order to improve Processing efficiency and the realization of synchronous positioning grinding of the workpiece and the grinding head in the processing process, a spindle with high rigidity, high rotation accuracy, low vibration, compact structure, reliable positioning, and automatic clamping of the workpiece in the machining process is urgently sought. Market demand. Contents of the invention [0003] The purpose of the present invention is to provide a servo direct-connected spindl...
