Figure 1 and Figure 2 As shown, in one or more embodiments, the bearing disassembly fixture of this utility model includes a cylinder 1, a sliding seat 2, a clamping cylinder 3, and a screw 4.
[0025] Figure 3 This is a cross-sectional structural diagram of a bearing disassembly fixture according to this utility model. Figure 1 , Figure 2 and Figure 3As shown, the cylinder 1 is generally cylindrical, and an end plate 11 is formed near one end. A threaded hole is provided in the middle of the end plate 11 to form a threaded connection with the screw 4. Furthermore, a sliding seat 2 is adjustablely arranged inside the cylinder 1. The sliding seat 2 is generally cylindrical, and its outer diameter matches the inner diameter of the cylinder 1, allowing the sliding seat 2 to slide within the cylinder 1. Specifically, a mounting groove is provided on the sliding seat 2, which is generally rectangular and located near the end of the sliding seat 2 away from the end plate 11. A through hole is also provided on the sliding seat 2 to match the screw 4, through which the screw 4 extends into the mounting groove. Furthermore, a hinge shaft 21 is provided on the sliding seat 2, passing through the mounting groove. Two hinge shafts 21 are provided, extending chordally along the sliding seat 2. Specifically, four countersunk holes are provided on the sliding seat 2. The four countersunk holes are arranged in pairs, and each pair of countersunk holes is used to install a corresponding hinge shaft 21. Based on Figure 3 As shown, the mounting groove extends in the inward and outward direction and penetrates the sliding seat 2.
