Scale division positioning tool rotary table

Abstract

The invention discloses a scale division positioning tool rotary table and aims to provide a working table which is convenient to mount and move, high in working efficiency and capable of saving efforts during operation and machining and rotating scale division workpieces. The scale division positioning tool rotary table is achieved according to the technical scheme that a rotary shaft (4) is connected with a reset spring (2) through upright barrel stepped holes and a flange plate at the lower end of a circular cone rotating body (3); the flange plate at the lower end of the circular cone rotating body is positioned on a positioning stepped surface (11) of the upright barrel stepped holes; stepped grooves which are symmetrical relative to the axis in the diameter direction is formed in an upright barrel; a handle shaft with a locking cam (9) positions the locking cam on an inclined conical surface of the circular cone rotating body through assembling holes in the straight walls of the stepped grooves; a rotary plate (5) rotates division numbers to align the division numbers to division numbers on a machine base; the handle shaft (10) is rotated clockwise through a handle head so that the locking cam can make contact with the inclined conical surface of the circular cone rotating body, and the circular cone rotating body is locked and fixed so as to machine a workpiece.

Description

technical field [0001] The invention relates to a 360° circular indexing table device mainly used for milling machines, grinding machines, boring machines and fitter drilling; specifically, it is similar to a machine tool accessory device with a circular indexing plate. Background technique [0002] In the prior art, the rotary table is the main accessory of floor boring machines, boring and milling machines, and face milling machines. It is mainly used to support the workpiece and make it do linear and rotary adjustment and feed movement. Using it to clamp the workpiece can expand the manufacturability and shorten the auxiliary time. It can be used for boring, milling or grinding of straight line and circular plane, adjustment, feed, indexing, commutation and other movements. Equipped with a wide range of speed regulation, the best feed rate can be obtained. The rotary table is an auxiliary mechanism of machine tools such as floor boring machines, boring and milling mach...

AI Technical Summary

Problems solved by technology

Most of the rotary table is equipped by the manufacturer because of the machine-added indexing plate. This kind of rotary indexing plate is heavy in volume and complex in structure.

The indexing is rotated by the pot wheel and the pan rod. The indexing time is very slow, which is time-consuming and inconvenient for maintenance. If it is broken, it will almost have to be returned to the factory, which delays the production cycle.
