Description

TECHNICAL FIELD

[0001] The utility model relates to a shaft sleeve dismounting tool, in particular to a thin-wall copper tile dismounting tool. BACKGROUND

[0002] Generally, high-precision low-speed rotating parts on high-precision machine tools are mostly thin-wall copper tile 02 structures for heavy load and wear resistance, which have reliable transmission stability and long service life. The structure is to set multiple thin-wall copper tiles 02 on the mandrel 01, as shown in the structure Figure 1 When installing, the thin-wall copper tile 02 is heated to make it more convenient to install on the mandrel 01 by using the thermal expansion and contraction of copper, and is positioned by a positioning pin to fix the two relatively, and several lubricating oil grooves are also provided on the thin-wall copper tile 02 to ensure the rotating precision of the cooperation. However, due to poor lubrication and other conditions, the thin-wall copper tile 02 may be locked and unable to rotate, at which time the thin-wall copper tile 02 needs to be dismounted for maintenance. If the method of manually pulling out after heating is used, firstly, the mandrel 01 and the thin-wall copper tile 02 will expand at the same time, and the gap between them will not change, and secondly, the manual force is limited and the operation is not convenient, and the thin-wall copper tile 02 with tight cooperation is not easy to dismount.

[0003] The Chinese utility model patent with the authorized announcement number CN220660720U discloses a portable torque shaft sleeve special extractor, which can be used to pull out the thin-wall copper tile 02, which comprises a top rod, a mounting rack and two clamping jaws, the two clamping jaws are oppositely arranged and detachably connected with each other, and are used to clamp the sleeve of the torque shaft to be pulled out; the mounting rack is detachably mounted on the two clamping jaws, and the top rod is mounted on the mounting rack and is movable to approach or move away from the clamping jaws, and is used to push against the torque shaft and move the torque shaft. Generally, the sleeve is made of hard metal such as steel, and the two clamping jaws are clamped on the end face of the sleeve to pull it out. However, the mandrel 01 of the high-precision machine tool is provided with a limiting boss at one end, and the thin-wall copper tile 02 abuts against the limiting boss, which results in no working space for the clamping jaws to extend into, and the thin-wall copper tile 02 is soft in texture and thin in radial thickness, generally about 2mm, and the clamping jaws will cause damage and deformation to the end face of the thin-wall copper tile 02 when pulling it out.
