Description

Technical Field

[0001] The utility model relates to the technical field of grinding structures, and more specifically, to a grinding structure of a high-precision crankshaft spindle finishing grinder. Background Art

[0002] The grinding mechanism is a device with one or more rotating grinding components used to grind various parts. During operation, the grinding components grind and reduce various parts of the parts to make the surface smooth. This prevents the parts from shifting due to friction caused by surface roughness during machine operation, reduces friction between parts, and improves the accuracy of the parts. The grinding mechanism is mainly used for grinding and reducing parts.

It includes a nozzle body, one end of which is a cylindrical cavity with a part of the cylinder missing, and the other end is provided with a nozzle with a diameter smaller than the diameter of the nozzle body, and a liquid channel that passes through the outside and the cavity is opened along the axis of the nozzle body and the nozzle; a matching plug is clamped in the cavity. The nozzle grinding structure of the utility model, through the cooperation of the nozzle body and the plug, can clamp the plug for grinding during grinding, and has the characteristics of simple structure, high grinding precision and easy operation. In the process of realizing the utility model, the inventor found that the existing technology has the following problems:

[0004] Existing grinding structures generate tiny iron chips during use. These chips are so small that they are difficult to be noticed by people. Some extremely tiny chips will float in the air for a while before falling to the ground. During this time, the chips are inhaled into the lungs of construction workers, or they enter the machine through the gaps in the machine. This will have a certain impact on the use of the machine, especially for precision instruments, causing certain operating deviations. In addition, traditional grinding structures cannot perform full-body grinding on the parts to be ground or the grinding is not fine enough, which is extremely fatal to some precision parts.

[0005] Therefore, in order to solve the above problems, a grinding structure of a high-precision crankshaft spindle finishing grinder is proposed. Utility Model Content

The first rotating shaft 5 is installed on the side of the grinding assembly 4, and the first motor 6 is installed on the side of the first rotating shaft 5.

[0022] Among them: when the grinding mechanism 1 can perform precise grinding on the crankshaft main shaft, the spray assembly 2 can clean the crankshaft main shaft being processed, so that the iron filings generated by the grinding of the crankshaft main shaft will flow to the ground with the water flow, which not only reduces the iron filings inhaled by the workers, but also greatly reduces the probability of iron filings entering the machine. The fixing mechanism 3 can provide a placement space for the crankshaft main shaft that needs to be ground and fix the crankshaft main shaft at a reasonable grinding angle. The spray assembly 2 is installed above the grinding mechanism 1 by bolts, and the fixing mechanism 3 is placed below the grinding mechanism 1. The grinding mechanism 1 includes a grinding assembly 4, a first rotating shaft 5 and a first motor 6. The grinding assembly 4 is in direct contact with the crankshaft main shaft and grinds the surface of the crankshaft main shaft. The first motor 6 drives the first rotating shaft 5 to rotate, and the first rotating shaft 5 can drive As the grinding assembly 4 rotates, the first motor 6 provides rotational power for the grinding mechanism 1. The side of the grinding assembly 4 is installed with a first rotating shaft 5 by welding. The side of the first rotating shaft 5 is installed with a first motor 6 by welding. When the worker places the crankshaft main shaft on top of the fixing mechanism 3, the worker needs to fix the crankshaft main shaft at a suitable angle, and then start the fine grinder. The first motor 6 in the grinding mechanism 1 will rotate with the first rotating shaft 5 at the same speed, and the grinding assembly 4 welded to the first rotating shaft 5 will also rotate with the first rotating shaft 5 at the same speed. The grinding assembly 4 grinds the surface of the crankshaft main shaft, and the iron filings produced by grinding will flow to the ground with the water flow of the spray cleaning assembly 2, greatly reducing the iron filings in the air, which not only protects the health of the operating workers, but also protects the normal operation of the machine.

The spray diverter head 7 can divert the water flow in the spray outlet 8 so that the part of the crankshaft spindle that is finely ground can be fully flushed. The pressure reducer 9 can reduce the pressure of the water in the water pump 10 to slow down the flow rate of the water flow, so that the water flow will not affect the accuracy of the crankshaft spindle grinding during the flushing process. The water pump 10 can introduce the water flow into the spray assembly 2, and the water pipe 11 connects the parts in the spray assembly 2 so that the water flow can flow out smoothly from the spray outlet 8.

After the worker adjusts the upper and lower positions of the rotating component 14 and fixes it, the worker needs to place the crankshaft main shaft on the placement fixture 23 and then fix it. When the position is correct, the worker needs to turn on the second motor 21 in the placement box 20, and the second motor 21 starts to rotate and drives the second rotating shaft 22 to rotate. The second rotating shaft 22 also drives the placement fixture 23 to rotate, so that the outer wall of the fixed position of the crankshaft main shaft can be fully ground.

The placement fixture 23 provides a placement space for the crankshaft main shaft, and a connecting plate 19 is installed on the side of the slide block 18 by bolts. A placement box 20 is placed on the side of the connecting plate 19 away from the slide block 18. The second motor 21 is fixed to its inner wall inside the placement box 20 by bolts. A second rotating shaft 22 is placed on the side of the placement box 20 away from the connecting plate 19. The second rotating shaft 22 and the second motor 21 are connected by welding. A placement fixture 23 is installed on the side of the second rotating shaft 22 away from the placement box 20 by bolts. The slide 12 can provide a sliding groove for the rotating assembly 14, so that the rotating assembly 14 can move up and down.
