The corresponding workpiece placement stations 11 after press fitting are moved to the blanking stations 14 by the conveying mechanism 10, and then the barrels and stators assembled together are transferred to predetermined positions at the blanking stations 14.

Of course, it is also possible to feed all the work placement bits 11 normally. In addition, the feeding operation can also be performed at the press-fitting station 131 and the blanking station 14, the feeding of the cylinder can be performed after the cylinder is transferred to the heating station 132, and the feeding of the stator can be performed after the blanking of the assembled cylinder and stator.

The first direction is parallel to the conveying direction of the conveying mechanism 10, and the second direction is perpendicular to the conveying direction of the conveying mechanism 10.

The first direction is a fixed horizontal direction, and the second direction is a vertical direction.

It will be appreciated that the second driving element 213 is operative to drive the translation member 212 to move in a first direction to drive the first clamp 214 to move directly over the barrel on the workpiece placement site 11 and directly over the heating site 132 when the press-fitting site 131 is operated, and the third driving element 215 is operative to drive the first clamp 214 to move in a second direction to drive the first clamp 214 to move down to clamp the barrel on the workpiece placement site 11 and transfer the barrel to the heating site 132, and the fourth driving element 217 is operative to drive the second clamp 216 to move in a second direction to drive the second clamp 216 to move down to clamp the barrel on the heating site 132 and transfer the barrel to the stator on the workpiece placement site 11 when the next press-fitting site 131, and because the distance between the first clamp 214 and the second clamp 216 is equal to the distance between the first positioning portion 111 and the second positioning portion 112, the second clamp 216 is moved down to clamp the first clamp 214 on the stator placement site 11 and the barrel to move down to clamp the workpiece placement site 11, thereby improve the efficiency of the barrel 11.

The second clamp 216 may be adjusted in position relative to the first moving member 231 in the second direction to operate the first platen 232 such that the first platen 232 is capable of applying pressure to the first workpiece when moving in the second direction.

It will be appreciated that, after the second clamp 216 clamps the heated barrel and transfers the heated barrel to the stator, the second clamp 216 needs to adjust the position to make the first pressing plate 232 in an operating state, so as to avoid the second clamp 216 abutting against the barrel when the first moving member 231 moves downward in the second direction, therefore, during press fitting, the fourth driving element 217 drives the first moving member 231 to move in the second direction, and simultaneously makes the second clamp 216 adjust the position in the second direction, so that the first pressing plate 232 is in an operating state, so that only the first pressing plate 232 abuts against the barrel when the first moving member 231 moves downward, and thus, the barrel on the stator can be forced by the first pressing plate 232, so that press fitting of the barrel to the stator can be achieved.

In this embodiment, the fourth driving element 217 is fixed on the translation member 212, and the output end thereof is fixedly connected with the first moving member 231, and the fourth driving element 217 is an electric cylinder, which has high precision but small pressure, so that the device is suitable for press-fitting with smaller pressure.

The second surface of the first pressing plate 232 is a force application surface during press fitting.

It will be appreciated that when the barrel on the heating station 132 needs to be clamped, the second clamp 216 is moved downward in the second direction, the clamping end of the clamping portion 216a passes through the avoiding portion 232a and is exposed from the second surface of the first pressing plate 232, at this time, the heated barrel can be clamped by the second clamp 216, the standby barrel is transferred to the stator, then the second clamp 216 is released, and then the second clamp 216 is moved upward in the second direction, so that the clamping end of the clamping portion 216a is retracted above the second surface of the pressing plate, and the first pressing plate 232 is in a working state, so that the press-fitting of the barrel and the stator is realized through the first pressing plate 232.

In this embodiment, the clamping jaw of the second clamp 216 forms a clamping portion 216a, the avoiding portion 232a is a through hole penetrating through two ends of the first pressing plate 232, and a cross-sectional dimension of the through hole is larger than a cross-sectional dimension of the clamping portion 216 a.
