Summary of the Invention

[0004] The purpose of this invention is to provide a brush cleaning machine for cleaning the surface of crankshafts, which solves the problem that the brush cannot make direct contact with the entire crankshaft during cleaning because the crankshaft is composed of several sections of round shafts with different diameters, making crankshaft cleaning too cumbersome.

Detailed Implementation

[0024] The following is combined Figures 1 to 6 The present invention will be described in detail below.

[0025] A crankshaft surface cleaning brush cleaning machine includes a base 1, a support 2 on the top of the base 1, a spray pipe 201 on the side of the support 2 near the top, a crankshaft clamping frame 3 on the top of the base 1, a rotating shaft 202 connected to the middle of the support 2, a connecting plate 203 connected to the side wall of the rotating shaft 202, a cleaning brush 2031 hinged to the side wall of the connecting plate 203, a deflection rod 2022 rotatably connected to one side of the support 2, and several connecting plates 203 sleeved on the side wall of the rotating shaft 202, with the cleaning brushes 2031 on the side walls of adjacent connecting plates 203 having different lengths.

[0026] First, the crankshaft to be cleaned is placed in the middle of the crankshaft clamp 3 and suspended in the air. Then, several connecting discs 203 are connected to the rotating shaft 202 in the middle of the bracket 2. The cleaning brush 2031 is connected to the side wall of the connecting disc 203 and contacts the surface of the clamped crankshaft. The crankshaft and the rotating shaft 202 are driven to rotate by the motor, so that the cleaning brush 2031 can thoroughly clean the surface of the crankshaft. At the same time, during the rotation cleaning process, the spray pipe 201 will continuously spray water to rinse and make the cleaning more thorough. Meanwhile, the motor and the rotating shaft 202 are driven by a chain.

[0027] Meanwhile, the cleaning brush 2031 is connected to the deflection groove 2032 through the hinge shaft 2033. Through the deflection of the cleaning brush 2031 and its own flexibility, it can adapt to crankshafts of different diameters for contact cleaning. The cleaning brushes 2031 on the two adjacent connecting discs 203 have different lengths, which can adapt to different diameters on the crankshaft.

[0028] Furthermore, the rotating shaft 202 also includes a limiting plate 2021, a mating groove 2026, a pressing block 2027, and a stop block 2028. The limiting plate 2021 is connected to the side wall of the rotating shaft 202. The mating groove 2026 is opened at one end of the rotating shaft 202. The pressing block 2027 is connected to the mating groove 2026 near the top. The stop block 2028 protrudes from the bottom of the mating groove 2026. The pressing block 2027 is connected to the groove near the top of the mating groove 2026 by a spring, and the pressing block 2027 is inclined towards the side facing the deflection rod 20222.

[0029] Furthermore, the deflecting rod 20222 also includes an abutment block 2023, a connecting shaft 2024, and a rotating disk 2025. The abutment block 2023 protrudes from one side of the deflecting rod 20222, the connecting shaft 2024 is hinged to one end of the deflecting rod 20222, the rotating disk 2025 is located at one end of the deflecting rod 20222, and the connecting shaft 2024 is rotatably connected to one side of the bracket 2 via the rotating disk 2025. The abutment block 2023 engages with the mating groove 2026, and the top of the abutment block 2023 is also provided with an opening that engages with the pressing block 2027. The bottom of the abutment block 2023 is in contact with the top of the abutment block 2028.

[0030] Furthermore, the connecting plate 203 also includes a deflection groove 2032, a hinge shaft 2033, a fitting ring groove 2034, and a limiting ring 2035. The deflection groove 2032 is formed on the side wall of the connecting plate 203. The hinge shaft 2033 is set at one end of the cleaning brush 2031. The fitting ring groove 2034 is formed on one side of the opening in the middle of the connecting plate 203. The limiting ring 2035 protrudes from the side of the opening in the middle of the connecting plate 203 away from the fitting ring groove 2034. The cleaning brush 2031 is connected to the deflection groove 2032 through one end of the hinge shaft 2033, and there are gaps between the two sides of the deflection groove 2032 and the two sides of one end of the cleaning brush 2031. The limiting ring 2035 is a circular protrusion on one side of the opening in the middle of the connecting plate 203 that mates with the deflection groove 2032. Grooves are formed on both sides of the limiting ring 2035, and tightening bolts are threaded into the grooves on both sides of the limiting ring 2035.

[0031] The following is a specific implementation process of the present invention. First, when the cleaning brush 2031 contacts the crankshaft for cleaning, when it comes into contact with crankshafts of different diameters, the cleaning brush 2031 will deform due to its own flexibility to adapt to the crankshafts of different diameters. At the same time, if the diameter change is too large, the cleaning brush 2031 will exert a certain force when rotating after deformation, causing the cleaning brush 2031 to deflect at a certain angle in the deflection groove 2032 through the hinge shaft 2033 at one end, thereby reducing the distance between the cleaning brush 2031 and the crankshaft, so as to adapt to the surface of the crankshaft with an excessively large diameter. The torsion springs set at both ends of the hinge shaft 2033 can also be reset after disengaging from the crankshaft surface.

[0032] When cleaning crankshafts of different lengths, a single connecting disc 203 cannot cover a section of the crankshaft. By rotating the limiting disc 2021 on one side, it moves along the rotating shaft 202 to the deflection rod 20222 via a thread. Then, the deflection rod 20222 is manually controlled to apply pressure, causing it to deflect along the hinge part of the connecting shaft 2024 and separate from the mating groove 2026 at one end of the rotating shaft 202. The diameter of the connecting disc is then controlled to separate from one end of the rotating shaft 202. The connecting discs 203 of the cleaning brushes 2031 with different lengths are then adjusted to move closer together, thereby expanding the width of the cleaning brushes 2031 of different lengths to accommodate crankshafts of different lengths.

[0033] After adjusting the connecting disc 203 with cleaning brushes 2031 of different lengths, the deflection rod 2022 is reset, allowing the abutment block 2023 at one end of the deflection rod 2022 to re-fit into the mating groove 2026. At the same time, the mating groove 2026 has a pressing block 2027 protruding on one side of the opening. The side of the pressing block 2027 near the abutment block 2023 is triangular, so that when the abutment block 2023 is engaged and disengaged, the pressing block 2027 will be compressed and contracted to allow the abutment block 2023 to pass through. After the abutment block 2023 is engaged with the mating groove 2026, the pressing block 2027 is reset and ejected by the spring, which will limit the abutment block 2023 to a certain extent, so that the deflection rod 2022 will not deflect on its own.

[0034] Finally, when adjusting the width of the connecting plate 203, as the rotating plate 2025 approaches, the fitting ring groove 2034 on one side of the connecting plate 203 will engage with the subsequent limiting ring 2035, allowing the two connecting plates 203 to fit together. Then, by threading a tightening bolt onto the limiting ring 2035, it is pressed against the surface of the rotating shaft 202, thereby making the connecting plate 203 and the rotating shaft 202 fixedly connected. When the rotating shaft 202 rotates, it will drive the connecting plate 203 to rotate together.
