Turbo-type indexing turnplate

Abstract

The invention discloses a turbo-type indexing turnplate, relates to the field of machining equipment, and aims at providing a novel indexing plate high in indexing efficiency and indexing accuracy. The turbo-type indexing turnplate is characterized by also comprising a drive worm and a driven worm separately located at two sides of a worm wheel and meshed with the worm wheel; one end of the drive worm is connected with a motor; the motor is connected with a controller; and an indexing plate mounting shaft is provided with an overrunning clutch. The turbo-type indexing turnplate has the beneficial effects that the two worms are located at two sides of the worm wheel and are meshed with the worm wheel, so that the influence of inter-lobe clearance between a gear and a rack on indexing is eliminated, and indexing accuracy is high; the drive worm is directly driven by the motor to rotate, so that indexing efficiency is high; and the indexing plate mounting shaft is provided with the overrunning clutch, so that the phenomenon that the indexing accuracy is influenced due to the fact that the indexing plate rotates in a process of clamping or cutting can be effectively prevented.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a turbine-type indexing turntable in a metal cutting machine tool. Background technique [0002] In the machining process, it is often necessary to process some grooves or patterns on the circumference of the workpiece. In these processes, there are quite strict requirements on the positional relationship between the grooves or patterns on the workpiece. Therefore, in order to ensure the machining accuracy, the angle of each rotation of the workpiece needs to be mastered very accurately, and the guarantee of machining accuracy is the best. The most important thing is the accuracy of the indexing. If the indexing accuracy is high, the processing accuracy will be high. The indexing in mechanical processing is usually completed by using the indexing plate. The existing indexing plates can be roughly divided into indexing plates such as gears, worm gears and molds, an...

Problems solved by technology

The existing indexing plates can be roughly divided into indexing plates such as gears, worm gears and molds, and most of these indexing plates are manually indexed, and the indexing efficiency is low; between the gear and the gear (or rack), There is a gap between the teeth of the worm wheel and the worm, and the indexing accuracy is low; the indexing plate rotates in one direction due to the cutting force during processing, which affects the indexing accuracy
