方法では生産合理化に結び付かない。However, there is no apparatus for simultaneously assembling a plurality of members such as a brake cap and a clutch cap, which have different fixing methods, such as a work to be clamped and a work to be press-fitted. The reason is that the tightening is performed by rotation, while the press-fitting is performed by the straight-ahead direction in the axial direction, and it is quite difficult to simultaneously perform the things having different functional directions. It is considered that the reason is that if the press-fitting work piece is firmly fixed or the press-fitting piston is not inserted, shaft runout or tilt occurs and smooth press-fitting is difficult. For this reason, conventionally, for example, a tightening mechanism and a press-fitting mechanism are respectively arranged in the robot hand, and after the brake cap gripped by the tightening mechanism is moved to the cap tightening position by the robot hand and tightened, Although it is constructed such that the clutch is moved to the clutch cap position and the clutch is press-fitted by the press-fitting mechanism, such an individual assembling method does not lead to rationalization of production.

方法を提案する。The present invention relates to a method for assembling a workpiece to be fastened and a workpiece to be press-fitted, which are arranged in parallel and adjacent to each other, such as a brake cap and a clutch cap. A tightening mechanism and a press-fitting mechanism are arranged adjacent to each other so as to correspond to the separated positions of the two works, and the work to be tightened is first tightened by using the tightening mechanism, and the work to be tightened to the tightening mechanism. A method of assembling a plurality of works, characterized in that the press-fitting mechanism is used to press-fit a work to be press-fitted while maintaining the engagement.

合、かじり等が発生し円滑な圧入が困難な場合がある。According to the first aspect of the present invention, for example, the clutch cap as the press-fitted part cannot be press-fitted unless the position is determined, but by tightening the brake cap as the work to be tightened, the brake cap and the tightening thereof. The attaching mechanism functions as a fixing guide on the clutch cap side, which eliminates the need for a special fixing mechanism on the press-fitting mechanism side. Further, in the conventional press-fitting device, the press-fitting is performed by a fluid cylinder or the like, so that the initial press-fitting speed and the final press-fitting speed are press-fitted at the same speed. In such a case, galling may occur and smooth press-fitting may be difficult.

It is possible to absorb shaft run-out and perform initial press-fitting to a precise press-fitting position. After that, the main press-fitting is performed with the press-fitting force on the press-fitting mechanism side, so that sufficient and smooth press-fitting can be performed.
