[0019] 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.
[0020] like Figure 1-3As shown, the utility model provides a technical solution: a disassembly device for mechanical maintenance, including a docking seat 1, and the docking seat 1 is adapted to a mechanical mounting part 8 (i.e., the main shaft part), and a mechanical part 9 is installed on the mechanical mounting part 8 (the central part of the mechanical part 9 is sleeved on the inner hole of the main shaft part), and there are 8 M16 bolt holes on the mechanical mounting part 8, the bolt holes are installed in the same way as the stud screw 4, the external thread 5 is adapted to the bolt holes on the mechanical mounting part 8, and an ejector seat 2 is installed on the docking seat 1, and both the docking seat 1 and the ejector seat 2 are circular, and the docking seat 1 is provided with 8 positioning holes 3, and the 8 positioning holes 3 are all adapted to be equipped with stud screws 4, the diameter of the positioning holes 3 is larger than the diameter of the stud screws 4, so that the stud screws 4 can pass through the positioning holes 3 so that the external threads 5 are connected to the bolt holes on the mechanical mounting parts 8, one end thread head of the plurality of stud screws 4 is the external thread 5, the other end thread head of the plurality of stud screws 4 is the adjusting thread 6, and the adjusting thread 6 is connected with a tightening nut 7, the docking seat 1 is aligned and fitted with the mechanical mounting part 8, and the plurality of stud screws 4 are passed through the positioning holes 3 and then connected to the mechanical mounting part 8 The threaded holes on the top are connected, and then multiple tightening nuts 7 are rotated. The tightening nuts 7 move on the adjusting threads 6 and contact the docking seat 1, and the docking seat 1 is squeezed to move on the double-headed screw 4. The docking seat 1 drives the ejection seat 2 to squeeze into the inner hollow of the mechanical mounting part 8, so that the mechanical part 9 is ejected from the inner hollow of the mechanical mounting part 8, and the mechanical part 9 is disassembled from the mechanical mounting part 8. The diameter of the ejection seat 2 is smaller than the inner hollow diameter of the mechanical mounting part 8. In this way, the ejection seat 2 can enter the inner hollow of the mechanical mounting part 8 under the push of the docking seat 1. The central axis of the mechanical part 9 is pushed out of the inner hollow part of the mechanical mounting part 8. The rotation direction of the external thread 5 and the bolt hole on the mounting part 8 when connected is the same as the rotation direction when the rotating tightening nut 7 squeezes the docking seat 1. This arrangement can avoid the double-headed screw 4 from rotating and debonding from the bolt hole on the mounting part 8 when the external thread 5 of the double-headed screw 4 and the bolt hole on the mounting part 8 are connected when the rotating tightening nut 7 squeezes the docking seat 1, thereby ensuring the stability of the double-headed screw 4 after the external thread 5 and the bolt hole on the mounting part 8 are connected.
[0021] The operating steps of the utility model are:
[0022] The docking seat 1 is aligned and fitted with the mechanical mounting part 8, and multiple stud screws 4 are passed through the positioning holes 3 and connected with the threaded holes on the mechanical mounting part 8. Then, multiple tightening nuts 7 are rotated, and the tightening nuts 7 move on the adjustment threads 6 of the stud screws 4 and contact the docking seat 1. The docking seat 1 is squeezed to move on the stud screw 4, and the docking seat 1 drives the ejection seat 2 to squeeze into the inner hollow of the mechanical mounting part 8, so as to eject the mechanical part 9 from the inner hollow of the mechanical mounting part 8, and complete the removal of the mechanical part 9 from the mechanical mounting part 8.
