Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The tool for disassembling the bearing on the turning wheel of the cigarette making machine is characterized by comprising a threaded rod 2, a threaded sleeve 3 and a hollow ejector rod 4, wherein a threaded through hole 31 is formed in the threaded sleeve 3, the threaded through hole 31 is matched with the threaded rod 2, a nut 1 is fixedly connected to one end of the threaded rod 2 in a welding mode, the hollow ejector rod 4 is fixedly welded to one end, far away from the threaded rod 2, of the threaded through hole 31, the hollow ejector rod 4 is the same as the axis of the threaded through hole 31, the inner diameter of the hollow ejector rod 4 is equal to the diameter of the threaded through hole 31, a clamping edge 41 is arranged at one end, far away from the threaded sleeve 3, of the hollow ejector rod 4, a plurality of notches 42 are further formed in the axial direction of the hollow ejector rod 4, and the outer diameter of the hollow ejector rod 4 is the same.
Preferably, the first and second liquid crystal films are made of a polymer,the length of the threaded rod 2 is L, and the length of the hollow ejector rod 4 is L1Wherein L = 2L1The clamping edge 41 is further provided with a guide edge 43 at one end far away from the screw sleeve 3, and the clamping edge 41 and the guide edge 43 are integrally formed. The number of the notches 42 is 4-6, and the notches are uniformly arranged along the radial direction of the hollow ejector rod 4. The U-turn wheel bearing 6 is made of stainless steel.
The utility model is realized in such a way, in the disassembly process, firstly, the threaded rod 2 with the screw cap 1 is installed in the threaded through hole 31 in the screw sleeve 3, the threaded rod 2 is rotated to ensure that one end of the threaded rod 2 just contacts the hollow ejector rod 4 to stop rotating, after the threaded rod 2 is installed, the hollow ejector rod 4 is inserted into the U-turn wheel 5 with the U-turn wheel bearing 6 which is burned or broken, the hollow ejector rod 4 enters into the other end from one end of the U-turn wheel bearing 6 which is burned or broken, because the hollow ejector rod 4 is provided with the interference of the clamping edge 41, the inner wall of the U-turn wheel bearing 6 can extrude the clamping edge 41 when entering, at the moment, because the hollow ejector rod 4 is provided with the notch 42, the extruded clamping edge 41 deforms to enter into the through hole on the U-turn wheel bearing 6 until the clamping edge 41 reaches the other end of the through hole of the U-turn wheel bearing 6, at the moment, because the extrusion, the clamping edge 41 is deformed and restored and is clamped with the wall edge of the turning wheel bearing 6, then the threaded rod 2 is rotated to reach one end, provided with the clamping edge 41, of the hollow ejector rod 4, the threaded rod 2 is inserted into the hollow ejector rod 4, so that the clamping edge 41 is easy to deform to cause unhooking when the turning wheel bearing 6 is pulled out, finally, the nut 1 is fixed by using two knob tools, one knob tool is used for rotating the nut 3 on the nut 3, the nut 3 is withdrawn along the threaded rod 2 and the turning wheel bearing 6 is taken out from the turning wheel 5, the dismounting process is completed in one step, the dismounting process is simple and convenient, the maintenance cost is effectively reduced, and the maintenance efficiency is improved.
