Description

one

The invention relates to general engineering and can be used to create various machine tools and machines.

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

Figure 1 shows the pin connection, incision; in fig. 2 - section A-L of figure 1; in fig. 3 shows a section BB in FIG. in fig. 4 connection, plan view.

The connection (FIGS. 1 and 2) consists of the base part 1 and the part to be attached 2 with a groove 3 formed therein, in which a removable insert 5 connected to the base part with a pin 6 is installed and secured with a screw 4 by a screw 4, and connected by an item - a pin 7. Both parts are also interconnected by a pin 8 installed on a line, a perpendicular line connecting the centers of the pins 6 and 7.

The compound works as follows.

The pin 8 fixes the attachable part 2 in two coordinates in a common plane relative to the lower base. Replaceable insert 5 and tifta 6 and 7 fix the attachment part by the angular coordinate of the core;

relative to the base part.

Small errors in the center-to-center spacings of parts 1 and 2 are compensated for this by a small new, rotary insert 5 around the pin 7. Gaps around the perimeter of the insert 5, as well as its location, perpendicular to the line connecting the centers of the pins 11 and 6 allow this rotation. The fixing screw 4 of small diameter (supplied with a gap) does not prevent the insertion from self-insertion, but, in case of disassembly, keeps it in the adjusted position. Self-alignment of the insert over the actually performed center-to-center distances prevents increased forces and mashes when joining parts 1 and 2 on pins 8 and 6.

The interchangeable insert allows you to carry out the angular adjustment of the attachment part relative to the base. For this, the connection is disassembled by unscrewing the screw 4 and the removable insert is removed. In order to make an angular correction d oi, the fixing holes are machined with a new recalculated center-spacing distance f + l at the finished blank of a new interchangeable insert.
