[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figures 1-5 As shown, this embodiment provides a spacer pressing device, including a traveling frame device 1, a receiving platform device 2 and an extrusion system 3, the receiving platform device 2 and the extrusion system 3 are both installed on the traveling frame device 1, the traveling frame device 1 is used to drive the receiving platform device 2 and the extrusion system 3 to move, the receiving platform device 2 forms a clamping position 21, the clamping position 21 is used to place workpieces 4 of different shapes and sizes, the extrusion system 3 includes an extrusion power device 31, a flexible pressure plate device 32 and a correction device 33, the flexible pressure plate device 32 and the correction device 33 are installed at the output end of the extrusion power device 31, the output end of the extrusion power device 31 passes through the clamping position 21, the extrusion power device 31 pulls the flexible pressure plate device 32 to extrude the spacer 5, and flexibly extrude the spacer 5 into the prefabricated hole position of the workpiece 4, the correction device 33 is actuated to ensure the posture of the spacer 5.

[0032] The receiving platform device 2 includes a receiving plate and a receiving fixture. The receiving plate is fixed on the traveling frame device 1 through the receiving fixture. When installing different workpieces 4, receiving plates of different sizes are replaced to make receiving plates of different sizes.

[0033] The extrusion power device 31 includes an extrusion power cylinder, a hydraulic station and a hydraulic valve. The hydraulic power cylinder is fixedly mounted on the walking frame device. The hydraulic station and the hydraulic power cylinder are connected through a hydraulic valve. The hydraulic station provides high-pressure oil, and the hydraulic valve is used to control the action of the hydraulic power cylinder.

[0034] The flexible pressing plate device 32 includes an upper pressing plate 321, a plurality of guide columns 322, a flexible extrusion plate 323 and an extrusion spring 324. The upper pressing plate 321 is fixedly mounted at the output end of the extrusion power device 31, and each guide column 322 is mounted on the lower side of the upper pressing plate 321. Each guide column 322 passes through the flexible extrusion plate 323, and each flexible extrusion plate 323 slides along the guide column 322. The extrusion spring 324 is located between the flexible extrusion plate 323 and the upper pressing plate 321. During press-fitting, the extrusion power cylinder retreats to drive the upper pressing plate 321 to descend. When the upper pressing plate 321 of the flexible pressing plate device 32 descends, the flexible extrusion plate 323 is guided by each guide column 322, and the flexible extrusion plate 323 slides along each guide column 322. The extrusion spring 324 squeezes the flexible extrusion plate 323. The flexible extrusion plate 323 gives flexible extrusion to the spacer 5 to prevent the spacer 5 from being forcibly squeezed into the prefabricated hole when it is deflected, thereby causing damage to the workpiece 4 and the spacer 5.

[0035] The correction device 33 includes a correction ring 331, a slewing bearing 332 and a correction motor 333.

The correction motor 333 is transmission-connected to the correction ring 331. The first extrusion protrusions 3311 and the second extrusion protrusions 3231 are squeezed against each other under the drive of the correction motor 333. When the first extrusion protrusions 3311 and the second extrusion protrusions 3231 are squeezed against each other, they must be squeezed from the highest point of the flexible extrusion plate 323. That is to say, when the first extrusion protrusions 3311 and the second extrusion protrusions 3231 are squeezed against each other, the correction of the spacer 5 can be completed.

[0036] A first gear ring 3312 is provided on the correction ring 331, and a first gear 3331 is provided at the output end of the correction motor 333. The first gear 3331 is meshed with the first gear ring 3312, and the correction motor 333 drives the correction ring 331 to rotate, thereby driving the second protrusion and the first protrusion at the highest position to squeeze each other, thereby completing the correction of the spacer sleeve 5.

[0037] The traveling frame device 1 comprises a traveling frame 11 and a plurality of traveling wheels 12 , each traveling wheel 12 is mounted on the traveling frame 11 , the receiving platform device 2 and the extrusion system 3 are both mounted on the traveling frame 11 , and the traveling frame 11 is transferred in position under the action of the traveling wheels 12 .

[0038] The press-fitting method of the spacer press-fitting device comprises the following steps:

[0039] S1: The walking frame is pushed to the work station;

[0040] S2: placing the workpiece 4 on the clamping position 21, and placing the spacer 5 on the prefabricated hole position of the workpiece 4;
