[0032] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0033] Example:

[0034] like Figure 1 , 2 As shown in Figure 3, this utility model provides a bearing press-fitting device, including a press-fitting machine 101, a receiving platform 102, a sliding groove 103 and a mounting hole 104 on the receiving platform 102, a receiving cylinder 201 detachably disposed in the mounting hole 104, a connecting seat 202 disposed on the receiving cylinder 201, and the connecting seat 202 being bolted to the press-fitting machine 101. The receiving cylinder 201 has a pick-and-place hole 203.

[0035] The press-fitting machine 101 in this press-fitting equipment can be a traditional press-fitting device. During use, the receiving cylinder 201 is placed inside the mounting hole 104, and the connecting seat 202 is connected to the receiving platform 102 on the press-fitting machine 101 using bolts. During operation, the rotating shaft can be inserted into the receiving cylinder 201, with the bearing located at the top of the receiving cylinder 201. The receiving cylinder 201 supports the bearing, providing space for the rotating shaft during press-fitting. Simultaneously, the arrangement of the receiving cylinder 201 prevents bearing displacement during press-fitting. Furthermore, receiving cylinders 201 with different inner diameters can be selected according to the diameter of the rotating shaft to adapt to different application situations.

[0036] like Figure 2 , 4 As shown, in this embodiment, a slider 301 is slidably disposed in the slide groove 103. A support assembly is disposed on the slider 301 and can be lifted and lowered by an elastic member 304. The support assembly includes a lifting rod 302 that can be lifted and lowered and passes through the slider 301. A groove 105 is provided on the press machine 101 for the lifting rod 302 to slide and rise and fall. A receiving seat 303 is detachably disposed at the end of the lifting rod 302. The elastic member 304 is disposed between the receiving seat 303 and the slider 301.

[0037] After the shaft and bearing are installed, the workpiece to be pressed is placed on the receiving seat 303. Different shaped receiving seats 303 are installed to match different workpieces, so that the receiving seat 303 can cooperate with the holes, grooves or protrusions on the workpiece to support it. After the workpiece is placed, the pressing machine 101 is started. During the pressing process, the pressing head of the pressing machine 101 pushes down, causing the workpiece to be pressed down, and the lifting rod 302 slides in the slider 301 to compress the elastic element 304 until the workpiece and bearing are pressed. Then, the pressing head is controlled to rise, and the workpiece, bearing and shaft rise together under the restoring ability of the elastic element 304, so that the shaft is partially or completely removed from the receiving cylinder 201, so that the pressed workpiece can be removed.

[0038] like Figure 2 , 4 As shown, in this embodiment, an adjustment assembly connected to the slider 301 is provided on the receiving platform 102. The slider 301 is driven to slide within the slide groove 103 by the adjustment assembly. The adjustment assembly includes a mounting bracket 401 provided on the receiving platform 102. The mounting bracket 401 is located on one side of the slide groove 103. A lead screw 402 is screwed onto the mounting bracket 401. The end of the lead screw 402 is rotatably connected to the slider 301, and a handle 403 is provided at the end of the lead screw 402.

[0039] The handle 403 can drive the screw rod 402 to move, and the screw rod 402 drives the sliding block 301 to slide in the sliding groove 103 during movement, so that the position of the receiving seat 303 is adjusted, thereby facilitating supporting different workpieces, and the application range of the equipment is improved.

[0040] The specific use mode and beneficial effects of the utility model are as follows:

[0041] The bearing with the rotating shaft can be pressed and mounted, and the rotating shaft can be inserted into the receiving cylinder 201 downward during pressing and mounting, so that the bearing can be supported by the receiving table 102, and different rotating shafts of different sizes can be fixed by replacing the receiving cylinder 201 of different inner diameters. The workpiece with the pressing device is placed on the receiving seat 303, the position of the sliding block 301 in the sliding groove 103 is adjusted by rotating the screw rod 402, the position of the receiving seat 303 is adjusted, thereby facilitating supporting the workpiece by cooperating with the protrusion or the groove 105 on the different workpieces, avoiding displacement of the workpiece during pressing and mounting, and the workpiece is driven downward by the pressure head of the pressing machine 101 to compress the elastic member 304 during pressing and mounting, the pressure head of the pressing machine 101 is lifted after pressing and mounting is completed, the workpiece is reset under the action of the elastic member 304 and drives the bearing and the rotating shaft to rise until the rotating shaft is separated from the receiving cylinder 201, so that the device can quickly press and mount the bearing with the rod, and the pressed workpiece and the bearing are conveniently taken and placed.

[0042] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and it is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious for those skilled in the art. Therefore, these modifications or improvements made without deviating from the spirit of the utility model all belong to the scope of protection required by the utility model.
