Description

one

The invention relates to the field of machine tools and can be used in the fixing units of rotary-dividing devices.

Known locking including separating fingers mounted on the faceplate, and the locking device containing the stop 1.

The disadvantage of this device is a flexible element that acts as a stop.

The purpose of the invention is to increase the reliability and accuracy of fixation.

For this purpose, a bar is inserted into the locking device, which is installed with the possibility of vertical movement and located at the time of fixation between the next separating finger and the stop, which is made of two parts, spaced relative to each other with a gap for the passage of the divider leg.

FIG. 1 shows the top plate, a cross-section along the locking pin; in fig. 2 shows section A-A in FIG. one; in fig. 3-6 shows the steps for fixing the swivel plate.

The locking mechanism consists of rigidly mounted on a fixed base 1 stop 2, pivoting fingers 3,

rigidly mounted on the plate 4, the bar 5, resting on the plunger 6, which is in the guide sleeve 7, pressed into the base 1. The plunger 6 is pressed into the locking pin 8, which enters the groove of the bar 5, which together with the stop 2 constitutes the locking pin device mechanism. The mechanism works as follows.

When the plate 4 is rotated, the dividing finger 3 moves away from the bar 5, which is led out from the working area (see Fig. 3), the finger 3 passes over the bar 5 (see FPG. 4). At the end of the turn of the plate 4

the strap 5 by the plunger 6 is inserted with a clearance by the stop 2, made of two parts, and the finger 3 (see Fig. 5). When reversing the plate 4, the plate 5 is pressed by the dividing finger 3 to the stop 2, making accurate and reliable fixation of the faceplate 4 (see Fig. 6).
