[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a hydraulic mechanical maintenance disassembly device, comprising a docking ring 1, and the docking ring 1 is adapted to a mechanical mounting part 8, and a mechanical part 9 is installed on the mechanical mounting part 8, an inner cavity of the docking ring 1 is provided with an internal thread 3, and a top tightening seat 2 is docked in the inner cavity of the docking ring 1, and an external thread 4 is provided on the outer side of the top tightening seat 2 to connect with the internal thread 3, a plurality of positioning holes 5 are provided on the docking ring 1, the number of the positioning holes 5 is 8, and the plurality of positioning holes 5 are adapted to be equipped with a threaded column 6, and the plurality of positioning holes 5 are adapted to be equipped with a threaded column 6 on the mechanical mounting part 8. The grooves are arranged one by one, and the threaded column 6 is adapted to the threaded groove. The number of positioning holes 5 and threaded columns 6 used during the disassembly operation is not less than six, and a tightening nut 7 is arranged on the threaded column 6. The docking ring 1 is aligned with the mechanical mounting part 9, and a plurality of threaded columns 6 are passed through the positioning holes 5 and connected with the threaded grooves on the mechanical mounting part 9. The docking ring 1 is squeezed by rotating the tightening nut 7 to achieve the fit and fixation between the docking ring 1 and the mechanical mounting part 9. A plunger 10 is arranged in the tightening seat 2. The plunger 10 is a one-way plunger. The manual hydraulic pump 12 is the plunger 10. When the end is injected with liquid, the ejector pin in the plunger 10 is pressed toward the other end to the center of the mechanical part 9, so that the mechanical part 9 is ejected and disassembled from the mechanical mounting part 8, and the end of the plunger 10 facing away from the docking ring 1 is connected with a docking head 11, and the docking head 11 is connected to the infusion end of the manual hydraulic pump 12. After the tightening seat 2 is installed in the docking ring 1, the plunger 10 corresponds to the center of the mechanical mounting part 8. By rotating the tightening seat 2, the tightening seat 2 is tightened to the center of the mechanical part 9 by using the internal thread 3 and the external thread 4, and the infusion end of the manual hydraulic pump 12 is connected to the docking head. 11 is connected, and liquid is injected into one end of the plunger 10 through a manual hydraulic pump 12, and the other end of the plunger 10 is squeezed to the central part of the mechanical part 9, so that the mechanical part 9 is ejected and disassembled from the mechanical mounting part 8. The rotation direction of the threaded column 6 when connected to the threaded groove on the mechanical mounting part 8 is the same as the rotation direction when the tightening nut 7 is rotated to tighten the docking ring 1. This arrangement can avoid the threaded column 6 from rotating when the tightening nut 7 is rotated to tighten the docking ring 1 after the threaded column 6 is connected to the threaded groove on the mechanical mounting part 8, thereby ensuring the stability of the threaded column 6 after being connected to the threaded groove on the mechanical mounting part 8.
