Instrument lathe electromechanical integrated spindle box and auxiliary structure

Abstract

The technical schemes that a spindle box (13) is immersed into oil and lubricated, a flange disk (15) is used for transition, and a motor outer shell (17) is post-placed are adopted in an instrument lathe electromechanical integrated spindle box and an auxiliary structure. A hollow spindle (27) is installed by using three supporting points including a front supporting bearing (2), a back supporting bearing (10) and an auxiliary bearing (12), and an abrasion resistance shaft sleeve (1), the front supporting bearing (2) and a first thrust bearing (3) are arranged at the front end of the hollow spindle (27). The middle section of the spindle is movably matched with a second thrust bearing (6), and a first piston (4), a second piston (5), the second thrust bearing (6), a sliding block sleeve (7), a thrust sliding block (8) and a spring (9) are installed on the middle section of the spindle in sequence. The back supporting bearing (10), a motor rotor (11) and the auxiliary bearing (12) are arranged at the back end of the spindle. The technical scheme of respective water cooling is adopted for the spindle box (13), the flange disk (15) and the motor outer shell (17). The instrument lathe electromechanical integrated spindle box and the auxiliary structure have the advantages that the space utilization ratio of an instrument lathe is improved, the utilization revolution number is improved, mechanical noise is lowered, safety performance is improved, and energy saving and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the mechanical field and relates to an electromechanical integration structure of a spindle box of an instrument lathe. Background technique [0002] At present, the clamping mechanism of the traditional instrument lathe is that the chuck at the front end is connected to the hollow tie rod, and the pull rod works in a way that the pull rod passes through the hollow main shaft and is connected with the tensioning mechanism at the rear end. Therefore, the transmission mode is basically belt drive or gear drive. Among them, the belt transmission has a simple structure, low cost, and small axial installation space, but the mechanical vibration of high-speed rotation is large, and more installation space is required for the motor to connect to the belt pulley; the gear transmission structure is compact and complicated, but the noise and energy consumption of the teeth are large.
