要であるがエンドチエツクを必要とする。 BACKGROUND ART Conventionally, when parts are press-fitted by an automatic parts assembly device, the pressing force is set by hydraulic pressure or the like. By the way, the press force or press fit type is different for assembling various parts. For example, as shown in Fig. 1, Type A involves pressure assembly in which parts are seated on the shaft end, and this includes a press force check to check whether the parts are press-fitted with a predetermined press-fit margin. Therefore, an end check is required to check whether the parts are press-fitted to the end of the shaft. Further, in type B, the press-fit assembly is performed up to an intermediate point before reaching the shaft end, and a press-fit force check is required, but an end check is not required. Furthermore, in type C, the part is loosely fitted onto the shaft and is assembled by coming into contact with another part press-fitted onto the shaft end.In this case, a press force check is not required, but an end check is required. do.

In FIG. 2, 1 is a unit body into which parts are press-fitted. A working shaft 2 is provided in the unit body 1 so as to be movable forward and backward in the axial direction. The forward/backward movement mechanism for the work shaft 2 includes a connecting member 3 orthogonal to the work shaft 2.
is fixed, and a feed screw 4 positioned parallel to the work shaft 2 is screwed into one side thereof. This feed screw 4 is connected to a control motor 5, and the control motor 5 is controlled based on movement commands from a numerical control device (not shown).

る。 That is, press-fitting, charging form (type A in Fig. 1,
B, C) are commanded by M code, and standard pressure input TL is commanded by R code. The auto-cutting load TH is commanded as a percentage of the standard pressure input TL (Ex.TL x 150%), and the tolerance range of press-in force TL±E 1 is the standard pressure input
±% of TL, tolerance range of movement SH ±E 2
is commanded by the ±number of pulses with respect to the movement command value ZO.
そこで、第１図の種別Ａの圧入エンド形態の場

異常ER１とする。 Therefore, in the case of the press-fit end configuration of type A in Fig. 1, the control of M50 is to feed the work shaft 2 by a unit amount, and when the stroke reaches the intermediate point SL (for example, 2/3 point of the movement command value ZO), the standard pressure is input. A comparison is made with the TL, and if it is within the tolerance range TL±E 1 , the process proceeds as is, and if it is not within the tolerance range TL±E 1 , it is determined as an abnormality ER1.
正常の場合、圧入荷重がオートカツト荷重に達

囲SH±E2に入つていなければ異常ER２とする。 In the normal case, when the press-fitting load reaches the auto-cutting load, the feed of the work axis 2 is stopped and it is checked whether that point matches the movement command value ZO. As a result of this check, if it is within the tolerance range SH±E 2 , part W 1 can be fitted with the required fitting pressure to shaft W 2 , and shaft W 2
Confirm that it is seated normally at the end, and if it is not within the tolerance range SH±E 2 , it will be treated as an abnormality ER2.
次に、第１図の種別Ｂの圧入中間形態の場合Ｍ
５１は、作業軸２を単位量づつ送り込み、中間点

される。 Next, in the case of the press-fit intermediate form of type B in Fig. 1, M
51 feeds the work shaft 2 by unit amount and reaches the intermediate point.
The checking of the pressing force in SL is the same as in type A, and the stoppage of the feed of the work shaft 6 is controlled by the movement command value.
さらに、第１図の種別Ｃの装入エンド形態の場
合Ｍ５２は、圧入力チエツクは不要でありエンド
チエツクのみであるので、作業軸２を単位量づつ

か否かをチエツクする。その結果、許容範囲内で
あれば正常着座を確認し、許容範囲に入つていな
ければ異常とする。 Furthermore, in the case of the charging end configuration of type C in Fig. 1, M52 does not require a press force check, but only an end check, so the work shaft 2 is fed in unit amounts and stops feeding when the auto-cutting load TH is reached. Then, it is checked whether that point matches the movement command value ZO. If the result is within the allowable range, normal seating is confirmed, and if the result is not within the allowable range, it is determined to be abnormal.

入制御が行える効果を有している。 In this way, according to the device of the present invention, the work shaft that moves the press-fitting head is fed by the feed screw of the control motor, and the press-fitting load acting on the press-fitting head is measured by the load converter to control the control motor. Because of this, it is possible to control many types of parts with different press-in forces or press-fitting forms with the press-force force appropriate for each part based on a predetermined program, and the automatic cut function allows unreasonable force to be applied to the parts. Moreover, it has the effect that reliable press-fitting control can be performed by the function of confirming intermediate pressure input and the function of confirming seating.
