Description

The invention relates to mechanical engineering and can be used to install the locking elements in the fixtures.

The purpose of the invention is to increase the reliability of fastening and installation accuracy of the part being attached.

Fig, 1 shows the connection details; FIG x - view a in figure 1; on fig.Z - section bb in fig, 1.

The connection of parts includes a base part 1 with a hole 2, an attachable part 3 with a stop collar 4 and protrusions 5 located in the slots of the expanding element 7, having an axial threaded hole in which a screw 8 is placed, which interacts with the 1st cone condom with the petals - 9 detachable element, and elastic washer

10, mounted between the screw head and the fastener 11 of the attachment part.

The joint is assembled in the following manner. The attachable part with the expanding element installed in it, the screw and the elastic washer insert into the hole of the base part until it stops against the shoulder, then tighten the screw. When this occurs, the clamping element is fastened in the hole and at the same time the screw head presses the attachable part to the base part by means of an elastic washer.

Thus, an increase in the reliability and accuracy of the installation of the attachment part is achieved. by creating additional axial forces.
