Description

Technical Field

[0001] This utility model relates to the field of grinding machines, and in particular to a grinding machine with adjustable length. Background Technology

[0002] Grinding wheel machines are commonly used equipment for sharpening various cutting tools and tools. They are also used for grinding, deburring, and cleaning ordinary small parts. The electric motor of the grinding wheel machine drives the grinding wheel to rotate at high speed. When the material being processed comes into contact with the rotating grinding wheel, the abrasive grains of the grinding wheel cut and grind the material, thereby achieving the purpose of removing material, shaping, or polishing the surface.

[0003] However, existing grinding machines have a fixed length of exposed grinding wheel, which is not convenient for grinding workpieces of different sizes. The powder generated during grinding also affects the working environment. Therefore, we propose a grinding machine with adjustable length to solve the problems mentioned above.

The end of the lower rotating shaft 11 away from the second motor 10 is rotatably connected to the first support plate 5. This allows for automatic adjustment of the length of the grinding wheel 4, making it suitable for processing workpieces of different sizes and providing flexibility and convenience in use.

[0023] A dust collection box 15 is fixedly installed at the upper end of the workbench 1. An air pump 16 is fixedly installed at the inner end of the dust collection box 15, and an air intake 18 is fixedly installed at the outer end of the air pump 16. A filter plate 17 is fixedly installed at the inner end of the dust collection box 15, and an upper suction pipe 13 is fixedly installed at the outer end of the dust collection box 15. The outer end of the upper suction pipe 13 is fixedly connected to the upper cover 8. The lower cover 12 and the upper cover 8 are symmetrically arranged on the outer side of the grinding wheel 4. A lower suction pipe 14 is fixedly installed at the lower end of the lower cover 12. The outer end of the lower suction pipe 14 is fixedly connected to the outer end of the dust collection box 15. An air outlet 19 is opened at the outer end of the dust collection box 15, which can directly and effectively draw air from the outside of the grinding wheel 4 for filtration, facilitating the treatment of dust generated during the grinding process and improving the working environment.

[0024] Specific working principle:

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this adjustable-length grinding wheel machine, the exposed length of the grinding wheel disc 4 is adjusted according to the size of the workpiece to be ground. During adjustment, the first motor 6 and the second motor 10 are started. The first motor 6 drives the upper rotating shaft 7 to rotate. When the upper rotating shaft 7 rotates, it drives the upper cover 8 to rotate upward. The second motor 10 drives the lower rotating shaft 11 to rotate, and the lower rotating shaft 11 drives the lower cover 12 to rotate downward. When the exposed length of the grinding wheel disc 4 meets the processing requirements, the first motor 6 and the second motor 10 can be stopped. If the opening angle of the upper cover 8 and the lower cover 12 is too large, the first motor 6 and the second motor 10 can also be stopped. Motor 10 rotates in the opposite direction, causing the upper cover 8 to rotate inward and the lower cover 12 to rotate outward, thus reducing the length. During processing, the grinding motor 3 drives the grinding wheel 4 to rotate inside the upper cover 8 and the lower cover 12 to grind the workpiece. The air pump 16 draws air from outside the grinding wheel 4 through the air intake 18, the upper dust suction pipe 13 and the lower dust suction pipe 14, drawing the dust-containing air into the dust collection box 15. After being filtered by the filter plate 17, the air is discharged from the air outlet 19. This completes a series of operations for the length-adjustable grinding machine. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
