Description
Technical Field
The utility model relates to the technical field of disassembly and assembly of mechanical parts, in particular to an auxiliary device for disassembly of a shaft sleeve.
Background
The shaft sleeve is a cylindrical mechanical part sleeved on the pump shaft, the shaft and the shaft sleeve move together during rotation, and according to different types of pumps, the connection modes are various, and key slot connection is common. Typically a clearance fit is used with the shaft. The shaft sleeve is an important accessory in the pump, can play a role of protecting the shaft, is an indispensable part in a sealing system, and basically consists of the shaft sleeve and an O-shaped ring embedded in an inner hole groove.
The shaft sleeve is worn after being used for a period of time, and needs to be replaced. The step clearance between the shaft sleeve and the shaft is small, so that the shaft sleeve is not easy to disassemble by a tool; in addition, the inner hole and the shaft are rusted, so that the disassembly is more difficult, a common method is to use a copper bar for knocking, or take out after baking and heating, and the copper bar can be disassembled by adopting a violent mode such as mechanical cutting and forceful extrusion of an old shaft sleeve, so that the copper bar is easy to cause strain and mechanical damage around the shaft hole and destructive damage of the shaft sleeve.
Thus, there is a need for an auxiliary device for sleeve disassembly.
Disclosure of Invention
The utility model aims to provide an auxiliary device for disassembling a shaft sleeve so as to solve the problems in the background technology.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows.
The auxiliary device for disassembling the shaft sleeve comprises a fixed seat for sleeving the shaft sleeve, wherein the fixed seat comprises a side wall and a bottom end surface; a bottom threaded hole is formed in the bottom end face of the fixed seat, and a rotating rod with threads on the outer wall is arranged in the bottom threaded hole in a threaded manner; the side wall of the fixing seat is provided with a side threaded hole which is axially arranged, and a bolt for fixing the shaft sleeve is arranged in the side threaded hole.
Further optimizing the technical scheme, the fixing base is a U-shaped base.
According to the further optimized technical scheme, the fixing seat is formed by welding three metal plates together.
According to a further optimized technical scheme, the end part of the rotating rod can be connected with the motor through the connecting device.
Further optimizing the technical scheme, lateral part screw hole can set up a plurality of.
By adopting the technical scheme, the utility model has the following technical progress.
According to the auxiliary device for disassembling the shaft sleeve, the shaft sleeve is fixed on the fixed seat through screwing the bolt, and then the rotating rod is screwed in to enable the rotating rod to prop against the shaft, so that a user rotates the rotating rod, and the shaft sleeve are separated. The utility model has simple structure, convenient use and high disassembly efficiency, and can ensure that the workpiece is not damaged, deformed and hidden danger is avoided.

Detailed Description
The utility model will be described in further detail with reference to the drawings and the specific embodiments.
An auxiliary device for shaft sleeve disassembly is shown in combination with fig. 1-2, and comprises a fixed seat 1, a bolt 2, a lateral threaded hole 3, a rotating rod 4, a bottom threaded hole 5, a shaft sleeve 6 and a shaft 7.
The fixing seat 1 is a U-shaped seat and is used for sleeving the end part of the shaft sleeve 6. The fixing base 1 comprises a side wall and a bottom end surface, and is formed by welding three metal plates together.
The bottom end face of the fixing seat 1 is provided with a bottom threaded hole 5, a rotating rod 4 is arranged in the bottom threaded hole 5 through threads, and the outer wall of the rotating rod 4 is provided with threads.
Lateral threaded holes 3 are formed in the side walls of the fixing base 1, and the lateral threaded holes 3 are axially formed. The bolt 2 is arranged in the side threaded hole 3 and used for extruding the shaft sleeve 6, and the shaft sleeve 6 is tightly pressed on the fixed seat 1. The side threaded holes 3 can be arranged in a plurality, so that the stability of fixation is improved, the stress area can be increased, and the deformation amount is reduced.
The tip accessible connecting device of bull stick 4 is connected with the motor, replaces the manual work to carry out the rotation of bull stick 4, saves the labour.
When the utility model is in actual use, the fixed seat 1 is sleeved at the end part of the shaft sleeve 6 to be disassembled, and then the bolt 2 is screwed, so that the bolt 2 presses the shaft sleeve 6 on the fixed seat 1. The end of the handheld rotating rod 4 rotates to push the rotating rod 4 to the shaft sleeve 6, so that the force is applied to the shaft 7 end, and the shaft sleeve 6 is separated from the shaft 7 under the action of the force due to the fixation of the bolt 2 and the fixing seat 1 to the shaft sleeve 6. The rotating rod 4 can be connected with the motor through the bearing, the motor drives the rotating rod 4 to rotate, the shaft sleeve 6 is disassembled, and the disassembly speed is improved, so that the labor is saved.
