Technical Field
[0001] The utility model relates to the technical field of bearing processing, in particular to a hydraulic shaft and bearing separation device. Background Art
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.
[0003] During the assembly process of shaft and bearing, hydraulic press is usually used for pressing. When pressing the bearing by manual press, it is first necessary to calculate the pressing force generated by the interference between the shaft and the inner ring (a hydraulic press with a working pressure greater than the required pressure must be used).
[0004] When the shaft and bearing are separated, hydraulic equipment is also required for separation. However, during normal use, the existing separation equipment is generally fixed by a simple clamping structure. Such fixation is often unstable and has limited fixing specifications, which affects the stability and adaptability of the separation of the shaft and bearing. Therefore, a hydraulic shaft and bearing separation device is proposed to solve the above problems. Utility Model Content

A threaded hole located on the outside of the adjusting screw is opened inside the connecting block, and the threaded hole cooperates with the thread on the outside of the adjusting screw.
[0010] Furthermore, the separation block is L-shaped, and the separation block is rotatably connected to the front side of the support plate via a rotating shaft.
[0011] Furthermore, the placement piece includes a support ring with one end fixedly connected to the upper end of the processing table, the outer side of the support ring is threadedly connected to a fixing screw with one end passing through and extending to the inner side thereof, the fixing screw is rotatably connected to a clamping block at one end located on the inner side of the support ring, and the outer side of the clamping block is fixedly connected to a limiting rod with one end passing through and extending to the outer side of the support ring.

Therefore, the activated hydraulic rod can drive the separating block to the outside of the bearing to lift and separate the bearing on the shaft, so as to stably separate the bearing and adapt to bearings of different specifications.
[0016] 2. The hydraulic shaft and bearing separation device can clamp and fix the shaft placed in the support ring after the clamping block is moved and adjusted toward the center of the support ring through three fixed screws on the support ring, thereby further improving the separation stability and adaptability.

[0026] Among them, there are two connecting blocks 34, which are symmetrically distributed on the inner side of the connecting frame 32. The cross-section of the connecting frame 32 is U-shaped. A threaded hole located on the outside of the adjusting screw 33 is opened inside the connecting block 34, and the threaded hole cooperates with the thread on the outside of the adjusting screw 33. The thread on the outside of the adjusting screw 33 is divided into two sections, and the two sections of the thread are symmetrically distributed.

[0027] In addition, the separation block 37 is L-shaped, and the separation block 37 is rotatably connected to the front side of the support plate 35 via a rotating shaft, so that the separation block 37 located on the front side of the support plate 35 can rotate stably.
[0028] See also Figure 1 Or 4. In this embodiment, a placement piece 4 for placing shafts and bearings is provided on the processing table 1. The placement piece 4 includes a support ring 41 with one end fixedly connected to the upper end of the processing table 1.

After the shaft with the bearing is placed in the placement groove on the processing table 1 for pre-limited fixation, the three fixing screws 43 on the rotating support ring 41 can be used to drive the clamping block 42 to move and adjust toward the center of the support ring 41, and then the shaft placed in the support ring 41 can be clamped and fixed, so as to further improve the separation stability and adaptability.
