[0130] In this example, the first workpiece 5 is clamped by the first pressing part 1, and the second workpiece 6 is clamped by the second pressing part 2, and the detection part 4 is controlled to detect the relative position of the first workpiece 5 and the second workpiece 6; wherein the relative position represents the distance between the axis of the first workpiece 5 and the axis of the second workpiece 6 in the horizontal direction and the vertical direction.

[0131] If the determined relative position is not within the preset tolerance range, the first pressing part 1 is controlled to adjust the first workpiece 5 in the horizontal direction and / or the vertical direction so that the relative position is within the tolerance range.

[0132] If the determined relative position is within the preset tolerance range, the control detection unit 4 detects the workpiece distance between the first workpiece 5 and the second workpiece 6 in the horizontal direction.

[0133] The moving part 3 is controlled to move the first pressing part 1 according to the workpiece distance, so that the first workpiece 5 contacts the second workpiece 6; the moving part 3 is controlled to move the pressing distance, so that the first pressing part 1 presses the first workpiece 5 onto the second workpiece 6, thereby achieving the technical effect of automatic pressing of the first workpiece 5 and the second workpiece 6, and improving the pressing efficiency of the workpieces.

[0134] At the same time, the position of the first workpiece 5 can be adjusted in the horizontal and vertical directions by the first pressing part 1, and the relative position of the first workpiece 5 and the second workpiece 6 can be detected by the detection part 4. After ensuring that the first workpiece 5 and the second workpiece 6 are aligned, the first workpiece 5 and the second workpiece 6 are press-fitted, thereby realizing the press-fitting of first workpieces 5 and second workpieces 6 of different models, and expanding the application scope of workpiece press-fitting.
