Hereinafter, the operation of the present invention and a press-fit method of dissimilar parts will be described in detail.

The press-fit method of the present invention is largely classified into a press-fit process and a press-fit return process. First, the press-fit process will be described.

As shown in FIG. 3, which is a flow chart of a method of press-fitting the dissimilar parts, the first and second members A and a, which are input materials, are moved by the transfer cylinder 2a of the transfer means 2 to the bed 1. In addition to being positioned at the center portion, the step of fixing by the left and right fixing cylinders 3a and 3a 'of the fixing means 3 is completed, and when the transfer cylinder 2a of the transfer means 2 is advanced, the press-in means ( The load cell provided in the measuring unit 4c of 4) is adjusted to " 0 " points.

Subsequently, the first and second members A and a positioned in the bed 1 are lowered by lowering the moving rod 4a of the press-fitting means 4 to the position of the primary lower end sensing portion 5b. In addition to pressurizing) through a load cell provided in the measuring unit (4c) through the first pressing step to determine the progress of the indentation process by measuring the pressing force, the position of the first lower end detection unit (5b) is 1 Of course, it is detected through the lower end detection unit 5b '.

Thereafter, the load cell measuring pressure L of the measuring unit 4c is 20 Kgf. L If it is 100 Kgf, the pressing part 4b lowered to the position of the primary lower end detection part 5b is raised to the upper end detection part 5a, and the left and right fixing cylinders 3a and 3a 'of the fixing means 3 and 3' are raised. ), The pressing part 4b of the press-fit means 4 is lowered to the position of the secondary lower end detecting part 5c to pressurize the first and second members A, a and the measuring part 4c. ) Is subjected to a secondary pressing step of determining the progress of the indentation process by measuring the pressing force through a load cell provided at the load cell, and the position of the secondary lower end detecting unit 5c is detected by the secondary lower detecting unit 5c '. On the other hand, when the retraction of the left and right fixed cylinder (3a, 3a '), the load cell of the measuring unit (4c) is again adjusted to the "0" point.

Subsequently, the load cell measuring pressure L of the measuring unit 4c is 20 Kgf.
