[0002] During the press-fitting process, for example, when the sleeve and the shaft are in interference fit, a large force needs to be applied to the sleeve so that the sleeve is pressed onto the corresponding shaft, thereby achieving press-fitting of the sleeve and the shaft.
[0003] In the prior art, a support mechanism is used to support the press-fitting process of the shaft sleeve and the shaft member. The support structure includes a support rod for fixing the shaft member. The bottom end of the shaft member is embedded in the top end of the support rod, and the shaft member is threadedly connected to the support rod by bolts.

[0045] Reference Figure 1 There is a pad 14 in abutment with the first cylinder 1221 and the base plate 12. There are multiple pads 14. In this embodiment, there are four pads 14. The upper and lower sides of any pad 14 respectively form an abutment fit with the lower surface of the first cylinder 1221 and the upper surface of the base plate 12. The pad 14 provides a buffering effect on the first cylinder 1221 during operation, reducing the wear of the first cylinder 1221 during the pressure process.
[0046] Reference Figure 1A right-angled triangle-shaped reinforcing rib 15 is provided between the vertical plate 11 and the horizontal plate 13 near the second cylinder 1311. The two right-angled surfaces of the reinforcing rib 15 are respectively connected to the side of the vertical plate 11 away from the first cylinder 1221 and the side of the horizontal plate 13 away from the second cylinder 1311 through bolt threads. The setting of the reinforcing rib 15 improves the structural strength between the vertical plate 11 and the horizontal plate 13 near the second cylinder 1311, so that it can withstand greater loads and impact forces, thereby ensuring the stability and durability of the equipment under long-term use.
[0047] The implementation principle of the embodiment of the present application is: during actual operation, the staff first operates the first cylinder 1221 to adjust the height of the support rod 121, so that the wedge groove 1211 on the support rod 121 is located in the second limiting hole 1342, and then operates the second cylinder 1311 to adjust the extension and contraction of the load-bearing rod, so that the wedge surface 1321 of the load-bearing rod 132 forms a plug-in fit with the wedge groove 1211 of the support rod 121, and then fixes the shaft to the end of the support rod 121, and at the same time, the shaft sleeve is clamped on the shaft. The setting of the wedge surface 1321 enables the load-bearing rod 132 to disperse the force more evenly when under pressure, thereby increasing the load-bearing capacity of the support rod 121 on the shaft and the shaft sleeve during the pressing process, thereby achieving efficient and stable support for the shaft and the shaft sleeve during the pressing process.
