4*90-degree right-angle head automatic indexing device

Abstract

The invention provides a 4*90-degree right-angle head automatic indexing device. The automatic indexing device comprises a right-angle head box body and a ram component. A main shaft is mounted in the ram component in a concentric manner and is connected with a transmission shaft through a connecting shaft. The transmission shaft is connected to the right-angle head box body through an insertion pin mechanism. The ram component and the right-angle head box body mesh and are connected. The main shaft is connected with a taper sleeve through an end-face key. The taper sleeve is connected with the connecting shaft through a flat key. One end of the connecting shaft is fixedly connected to the transmission shaft and the other end is disposed in the main shaft. A main pop rivet is arranged at the top of the connecting shaft and a main shaft clamping jaw is connected to the main pop rivet. The automatic indexing device is simple in structure and low in cost; the difficulty in design of right-angle heads is reduced and the practicality of products is improved; a locking mechanism is increased, so that the time of manual head change is reduced, the production efficiency is increased and the automation is facilitated.

Description

technical field [0001] The invention relates to the field of indexing devices, in particular to an automatic indexing device for a 4×90° right-angle head. Background technique [0002] As we all know, the traditional automatic indexing right-angle head adopts the structure of the toothed plate, which can realize many kinds of indexing angles, but the processing cycle of the toothed plate is long and the cost is high. In addition, when the gantry boring and milling machine is changing the attachment head, the position of the keyway of the attachment head drive shaft is often incorrect, resulting in interference between the spindle end key and the drive shaft when the ram moves downward. Thereby needs the workman to spend a long time to go to the keyway position, and then just can make accessory head normal work. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an automatic indexing device for 4×90° right-angle he...

[0002] As we all know, the traditional automatic indexing right-angle head adopts the structure of the toothed plate, which can realize many kinds of indexing angles, but the processing cycle of the toothed plate is long and the cost is high

In addition, when the gantry boring and milling machine is changing the accessory head, the position of the keyway of the drive shaft of the accessory head is often incorrect, resulting in interference between the spindle end key and the drive shaft when the ram moves downward.

As a result, it takes a long time for workers to align the position of the keyway before the attachment head can work normally
