Description

The invention relates to general machining and can be used to create various machine tools of machines and mechanisms.

The purpose of the invention is to expand the functionality of the connection:.

Pa. Fig, 1 shows a pin connection, incision; in fig. 2 is a section: A and A in FIG. one; in fig. 3 section bb in fig. one; Fig. 4 shows the pin connection, a plan view.

The connection (Figures 1 and 2) consists of a base part 1 and an attachable part 2 with a pair made in it. slots 3 and 4. In groove 3 with a gap around the perimeter is installed and secured by means of a screw

The 5 insert 6 is connected to the base part with a pin 7, and with the attached part a pin 8.

a groove 4 provided with protrusions 9 is mounted and fixed by protrusions against displacement in the direction of the insert

6 replacing insert 10 attached to the part to be joined with a screw 11

and connected to the base part by a pin 12, and with the part to be joined - by a pin 13,

The connection works as follows.

The interchangeable insert 10 fixes the attachment in two coordinates X and Y in a common plane relative to the base part at the location of the pin 12. The interchangeable insert 6 and the fasteners 7 and 8 fix the attachment of the detail in the angular coordinate a, fully defined together with the insert 5, the relative position both

details. In the intercenter distances x b of parts 1 and 2, the xeboligio space is compensated for the sky: 1; by turning up: and 6 around pin 8. Clearances around the perimeter of insert 6 and its location perpendicular to the line connecting the centers of pins 7 and 13 , allow this turn to take place freely. The fixing screw 5 of small diameter, delivered with a gap, does not interfere with the self-installation of the insert 6, and, with possible disassembly, keeps it in the adjusted position. The self-alignment of the insert 6 at the actual intercenter distances L prevents an increase in the force and paste when assembling parts 1 and 2 on the pins 12 and 7. To make an adjustment, screw 5 and the insert 6 dismantle the fixing holes for the pins 7, 8, 12 and 13 process with new recalculated interceptor distances (E - i) and (2, l 2 y also with offset dX relative to the axis of symmetry. Four corrections of the compound can be made:

plane-parallel decrease in the X coordinate on Be jnmHHy and X, with D, 0;

Claims (1)

A PIN connection containing a base and attachable and replaceable insert attached to one of the parts by means of a screw and connected separately to each of the parts by pins, characterized in that, in order to expand the functionality, it is equipped with an additional replaceable insert located parallel to the main insert, and in the part connected to the removable insert with a screw, grooves are made in which the mentioned removable inserts are installed, one of the grooves being made with a gap around the perimeter of the insert, and the other is made with a high blunts, fixing the insert against displacement towards the insert installed with a gap.
