昭59−12534号公報参照）。(Prior art and its problems) Conventionally, the first press-fitting part is placed on a mounting table, and the first
Temporarily fit the second press-fitting part into the press-fitting part, and then
After fitting the positioning pins into the respective positioning holes of the press-fitting part and the second press-fitting part, the second press-fitting part is pressed by the press-fitting head placed above the mounting table, and the first press-fitting part and the second press-fitting part are pressed. An apparatus has been proposed in which two press-fitting parts are positioned and press-fitted (see Japanese Utility Model Application Publication No. 12534/1983).

があるという問題があつた。 By the way, there is no problem with the above device because the mounting table is of a fixed type, but if the mounting table is of a movable type such as a turntable that rotates in a horizontal plane, the pressure from the press-fitted head on the mounting table may be applied. There was a problem in that it was necessary to place a large backup cylinder below the mounting table in order to back up the applied pressure.

である。(Structure of the invention) Therefore, the present invention is an apparatus for positioning and press-fitting a first press-fitting part and a second press-fitting part,
A mounting table that places a first press-fitting part and moves in a horizontal plane;
A press-fitting head for press-fitting into a press-fitting part, and a press-fitting head disposed below the above-mentioned mounting table and supported by a lift cylinder while being biased upward via a spring.
When the lift cylinder is raised, positioning pins are inserted into the respective positioning holes of the first press-fitting part and the second press-fitting part, and a back-up table is provided for lifting the first press-fitting part from the mounting table, and one end is attached to the back-up table. They are connected and oscillate up and down in conjunction with the rise and fall of the back up table, and when the back up table is in the raised position and is moved down against the biasing force of the spring, the other end of the back up table touches the back up table. It is characterized by comprising a stopper arm that stops the back-up table from moving downward.

パアームで当て止めるようにしたものである。(Effects of the invention) According to the invention, when the backup table supported by a spring is raised by a lift cylinder, the positioning pins are inserted into the respective positioning holes of the first press-fitting part of the mounting table and the second press-fitting part of the press-fitting head. At the same time, while lifting the first press-fitting part, the second press-fitting part is press-fitted into the first press-fitting part by the downward movement of the press-fitting head, and the second press-fitting part is lowered by the pressing force of the press-fitting head against the biasing force of the spring. The moved back-up table is stopped by a cut-off arm.
