[0033] With reference to Figure 3 - Figure 4The inner bottom surface of the waste liquid tank 4 is fixedly connected with a lifting air rod 6, the top end of the lifting air rod 6 penetrates through the filter screen 5, the top end of the lifting air rod 6 is provided with a moving plate 7, the lifting air rod 6 can drive the moving plate 7 to move linearly in the up-down direction when the lifting air rod 6 is started, the upper surface left side of the moving plate 7 is fixedly connected with a cleaning horizontal cylinder 8, the moving plate 7 can drive the cleaning horizontal cylinder 8 to move synchronously when the moving plate 7 moves, the internal cavity of the cleaning horizontal cylinder 8 is provided in a cylindrical structure, the left and right ends of the cleaning horizontal cylinder 8 are provided in an open structure, the size of the internal cavity of the cleaning horizontal cylinder 8 is adapted to the size of the shaft material, when the same batch of materials with the same diameter is processed, the material can be inserted from the right side of the cleaning horizontal cylinder 8, at this time, the cleaning horizontal cylinder 8 can scrape off the impurities and dirt adhered to the surface of the shaft material, so as to avoid affecting the precision during clamping and fixing, and causing the shaft material to slightly deviate, thereby affecting the turning precision.

[0034] The right side of the cleaning horizontal cylinder 8 is provided with a pushing unit, the pushing unit comprises a mounting plate 81, the mounting plate 81 is fixedly connected to the upper surface right side of the moving plate 7, the left side surface of the mounting plate 81 is fixedly connected with a plurality of electric push rods 82, the left end of the plurality of electric push rods 82 is fixedly connected with a pushing plate 83, the pushing plate 83 is located at the right side of the internal cavity of the cleaning horizontal cylinder 8, the pushing plate 83 is smaller than the internal cavity of the cleaning horizontal cylinder 8, the plurality of electric push rods 82 can drive the pushing plate 83 to move linearly in the left-right direction when the plurality of electric push rods 82 is started, when the plurality of electric push rods 82 drives the left side of the pushing plate 83 to move, the shaft material placed on the right side of the cleaning horizontal cylinder 8 can be pushed, so that the material can enter the internal cavity of the cleaning horizontal cylinder 8.

[0035] The right surface of the cleaning horizontal cylinder 8 is fixedly connected with a fixed plate 9, the upper surface of the fixed plate 9 is provided with a groove 10, the diameter of the groove 10 is greater than the diameter of the internal cavity of the cleaning horizontal cylinder 8, the bottom end of the groove 10 is located at the same horizontal plane as the bottom end of the internal cavity of the cleaning horizontal cylinder 8, the internal cavity of the groove 10 is in communication with the internal cavity of the cleaning horizontal cylinder 8, the internal cavity of the groove 10 is fixedly connected with arc-shaped scraping teeth 11, the internal diameter of the arc-shaped scraping teeth 11 is the same as the internal diameter of the internal cavity of the cleaning horizontal cylinder 8, the number of the arc-shaped scraping teeth 11 is several, and the several arc-shaped scraping teeth 11 are fixedly connected in a linear array in the left-right direction in the internal cavity of the groove 10.

[0036] The positions of the impurities or dirt on the surface of the material are observed, the material is placed in the internal cavity of the groove 10, and the impurities or dirt can be located between the gaps between the adjacent arc-shaped scraping teeth 11, so that the material can be aligned with the internal cavity of the cleaning horizontal cylinder 8, then the plurality of electric push rods 82 can be started to drive the left side of the pushing plate 83, at this time, the pushing plate 83 can push the shaft material to move right into the internal cavity of the cleaning horizontal cylinder 8, because the size of the internal cavity of the cleaning horizontal cylinder 8 is adapted to the size of the shaft material, when the shaft material enters the internal cavity of the cleaning horizontal cylinder 8, the cleaning horizontal cylinder 8 can scrape off the impurities and dirt adhered to the surface of the material, so as to avoid affecting the clamping and machining precision.

Since the lifting air rod 6 only drives the moving plate 7 to move up and down, when the area of the circular plate 14 and the circular groove 15 meets the supporting demand of the moving plate 7, the straight and stable movement of the moving plate 7 up and down can be ensured. When the surface of the filter screen 5 needs to be cleaned, the moving plate 7 can be directly removed, thereby reducing the shielding of the surface of the filter screen 5.

[0038] Working principle: when the same batch of mountain bike pedal shaft core raw materials with the same size and diameter are turned, first, the position of impurities or dirt on the surface of the raw material is observed and determined, then the raw material is placed into the groove 10, and the impurities or dirt are located between the adjacent arc-shaped scraping teeth 11. At this time, the shaft core raw material can be aligned with the inside of the cleaning horizontal cylinder 8 under the bearing and limiting of the arc-shaped scraping teeth 11. Then, the lifting air rod 6 is started to drive the moving plate 7 and the cleaning horizontal cylinder 8 to move upwards, so that the internal cavity of the cleaning horizontal cylinder 8 is aligned with the internal center of the three-jaw chuck 2. The multi-section electric push rod 82 is started to drive the push plate 83 on the left side, so as to push the shaft core raw material to the left side and pass through the cleaning horizontal cylinder 8, so that the shaft core raw material enters the inside of the three-jaw chuck 2. At this time, the three-jaw chuck 2 is started to fix the shaft core raw material. At the same time, when the shaft core raw material passes through the cleaning horizontal cylinder 8, the cleaning horizontal cylinder 8 can scrape and clean the impurities and dirt adhered to the surface of the raw material, so as to avoid affecting the clamping and machining precision, and to ensure the high-precision machining when turning the mountain bike pedal shaft core.
