The piston rod of the driving cylinder 5 is fixedly connected to the lower end of the pressing sleeve 4, and the cylinder body of the driving cylinder 5 is fixedly connected to the workbench 2.

[0033] In order to ensure the up and down movement of the pressing sleeve 4 and avoid its shaking, a positioning plate 6 is provided at the through hole, and an annular through groove 7 is formed between the positioning plate 6 and the through hole to match the pressing sleeve 4. The positioning plate 6 is fixedly connected to the workbench 2 through a guide frame 8; the pressing sleeve 4 is slidably connected to the guide frame 8, and a corresponding open through groove 9 is provided on the pressing sleeve 4. The guide frame 8 plays a role in fixing the positioning plate 6 on the one hand, and also plays a guiding role on the other hand.

[0034] When in use, the two workpieces to be pressed are stacked and placed on the pressing sleeve 4, and then the piston rod of the driving cylinder 5 is extended to make the two workpieces contact with the pressing rod 3; as the piston rod of the driving cylinder 5 continues to extend, the two workpieces are pressed together. After pressing, the piston of the driving cylinder 5 is retracted, and the pressing sleeve 4 moves down until its upper surface is flush with the workbench 2. At this time, the pressed workpieces can be taken out.

[0035] Furthermore, the shape of the guide frame 8 is preferably a "cross" shape; the open through slot 9 is correspondingly provided.

[0036] Furthermore, the driving cylinder 5 can be an oil cylinder or a gas cylinder.

[0037] Furthermore, it also includes a feed pushing mechanism, which includes a first pushing driving cylinder 10 and a second pushing driving cylinder 11; the first pushing driving cylinder 10 and the second pushing driving cylinder 11 are arranged opposite to each other and are both fixed on the workbench 2; the through hole is located between the first pushing driving cylinder 10 and the second pushing driving cylinder 11.

[0038] The two workpieces to be pressed are stacked and placed on the workbench 2, and the piston rod of the first push drive cylinder 10 is extended to push them onto the press sleeve 4, and the piston rod of the second push drive cylinder 11 is also extended to limit the position, so as to prevent the first push drive cylinder 10 from exceeding the press sleeve 4 during pushing. That is, the piston rods of the first push drive cylinder 10 and the second push drive cylinder 11 are extended to cooperate for positioning, so that the two workpieces to be pressed can be transferred to the press sleeve 4 after being stacked.

[0039] When the two workpieces to be pressed are stacked and can be transferred to the pressing sleeve 4, the piston rods of the first push drive cylinder 10 and the second push drive cylinder 11 are retracted.

[0040] Furthermore, it also includes a third push drive cylinder 12, which is fixedly connected to the workbench 2. When the press-fitting is completed, the piston rod of the third push drive cylinder 12 is extended to push out the press-fitted workpiece on the press sleeve 4.

[0041] Furthermore, according to actual needs (marking is required), a marking machine 14 is also provided, and the marking machine 14 can be a common laser marking machine 14 in the prior art. Since the workpiece after press-fitting has a fixed marking position, a rotating table 15 is also provided, and the rotating table 15 is connected to a driving mechanism, and the rotating table 15 is driven by the driving mechanism to rotate, so that the workpiece can be rotated to the required marking position. The rotating table 15 is rotatably connected to the workbench 2; the marking machine 14 is fixedly connected to the workbench 2 and is located above the rotating table 15.

[0042] It also includes a fourth pushing drive cylinder 13 , which is fixed on the workbench 2 and arranged opposite to the third pushing drive cylinder 12 , and the rotating table 15 is located between the fourth pushing drive cylinder 13 and the third pushing drive cylinder 12 .

[0043] After the press-fitting process, the piston rod of the third push-drive cylinder 12 is extended to push the press-fitted workpiece on the press sleeve 4 to the top of the rotating table 15; similarly, the piston rod of the fourth push-drive cylinder 13 is also extended to limit the position, so as to prevent the third push-drive cylinder 12 from exceeding the rotating table 15 during pushing. That is, the piston rods of the third push-drive cylinder 12 and the fourth push-drive cylinder 13 are extended to cooperate for positioning, so that the press-fitted workpiece is transferred to the rotating table 15.

[0044] Furthermore, the driving mechanism is a reduction motor 16, the housing of which is connected to the rotation of the workbench 2, and the output shaft of the reduction motor 16 is fixedly connected to the rotating table 15. That is, a common reduction motor 16 is used as a power to drive the workbench 2 to rotate, thereby rotating the press-fitted workpiece to the position where marking is required.

[0045] Furthermore, it also includes a fifth pushing drive cylinder 17 , which is fixedly connected to the workbench 2 , and the marked workpiece on the rotating table 15 is pushed out by the fifth pushing drive cylinder 17 .

[0046] Furthermore, the reduction motor 16 is provided as the driving force, and the following structure can be used to omit the use of the reduction motor 16.

[0048] There is a certain distance between the piston rod of the fifth push drive cylinder 17 and the rotating table 15; therefore, when the piston rod of the fifth push drive cylinder 17 is extended, the transmission belt 20 can be driven to move, thereby driving the driving gear 18, the transmission gear 19 and the rotating table 15 to rotate. Therefore, the fifth push drive cylinder 17 provides the rotating table 15 with rotational power, thereby eliminating the need for the reduction motor 16. After the marking is completed, the piston rod of the fifth push drive cylinder 17 continues to extend to push out the workpiece that meets the mark.

[0049] Furthermore, a push block 22 is fixed to the piston rod ends of the first push drive cylinder 10, the second push drive cylinder 11, the third push drive cylinder 12, the fourth push drive cylinder 13 and the fifth push drive cylinder 17; a positioning groove is provided on the push block 22. The positioning groove contacts the workpiece, thereby preventing the workpiece from moving at will.

[0050] Furthermore, the positioning groove is preferably a V-shaped groove. The first push drive cylinder 10, the second push drive cylinder 11, the third push drive cylinder 12, the fourth push drive cylinder 13 and the fifth push drive cylinder 17 are preferably pneumatic cylinders.

[0051] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
