Description

These two materials belong to medium carbon steel, and their strength, rigidity and toughness can meet the working requirements of the motor shaft. The motor shaft has a high speed and a small torque. It is made of 45# and does not require other heat treatment. The raw materials are in a normalized state, and the supply performance of the raw materials can meet the mechanical performance requirements of the motor shaft. In the production process of the motor shaft, the motor shaft will rust on the surface of the motor shaft after being piled up in the warehouse for a long time, which will affect the subsequent motor production quality.

[0038] See attached Figure 6The rust removal mechanism 4 includes a sliding frame 41, a C-shaped tooth plate 42, a limit block 43, a fixed block 44, a third motor 45, a bidirectional screw rod 46, a sliding plate 47, a threaded sleeve 48 and an arc-shaped rust removal block 49. The sliding frame 41 is slidably connected to the mounting frame 31 through the third sliding limit groove 32 and passes through the mounting frame 31. The C-shaped tooth plate 42 is fixedly connected to the top of the sliding frame 41. The limit block 43 is fixedly connected to the outside of the sliding frame 41 and is located inside the third sliding limit groove 32. The C-shaped tooth plate 42 is meshed with the second gear 36 and the third gear 38. The fixed block 44 is fixedly connected to the outside of the bottom of the sliding frame 41.

The arc-shaped rust removal block 49 is threadedly connected to the threaded sleeve 48 and is located on the outside of the threaded sleeve 48. Therefore, when the motor shaft is fixed and moved to the bottom of the rust removal mechanism 4, the operator turns on the second motor 35, and the second motor 35 rotates to drive the second gear 36 to The second gear 36 rotates, thereby driving the rotating shaft 37 to rotate, and the rotating shaft 37 drives the third gear 38 to rotate. The rotation of the second gear 36 and the third gear 38 drives the C-shaped toothed plate 42 and the sliding frame 41 to slide up and down on the mounting frame 31 until the arc-shaped rust removal block 49 moves to the outside of the top of the motor shaft. The operator turns off the second motor 35 and then turns on the third motor 45 to rotate. The rotation of the third motor 45 drives the bidirectional screw rod 46 to rotate. The rotation of the bidirectional screw rod 46 drives the two sliding plates 47 to move toward each other. The movement of the sliding plate 47 drives the threaded sleeve 48 and the arc-shaped rust removal block 49 moves until the two arc-shaped rust-removing blocks 49 contact and clamp the top surface of the motor shaft. At this time, the operator turns off the third motor 45 and turns on the second motor 35 again, and removes rust on the motor shaft by moving the arc-shaped rust-removing block 49 up and down. When the arc-shaped rust-removing block 49 is worn and damaged after long-term use, the operator can quickly remove the arc-shaped rust-removing block 49 from the threaded sleeve 48 by rotating the arc-shaped rust-removing block 49, and then replace the arc-shaped rust-removing block 49. After replacement, it is only necessary to rotate the arc-shaped rust-removing block 49 again to thread the arc-shaped rust-removing block 49 with the threaded sleeve 48.
