The crankshaft diameter of the EA888 engine under the popular flag adopts a process route of 'rough/finish turning, surface quenching and rough/finish grinding'. The AF90 grinding of the main journal, the excircle of the connecting rod journal and the excircle of the grinding flange is the process with the highest requirements on the machining precision and the surface roughness in the whole crankshaft production.

In general, a CBN (Cubic Boron carbide) grinding wheel is generally used in a grinding process, and is structured in such a way that CBN grinding strips are adhered to the circumference of a steel grinding wheel base body, and a machine tool corrects the surface of the CBN grinding wheel through a diamond wheel corrector after the grinding strips are worn. When the CBN grinding wheel is used for grinding, the grinding wheel needs to be replaced along with the gradual falling off and loss of CBN particles to a certain degree in the grinding and grinding wheel correcting processes.

However, it should be noted that the grinding wheel is originally placed horizontally in the magazine, and the grinding wheel is required to be mounted vertically when the grinding wheel is mounted on the main shaft of the grinding machine, so that the angle of the grinding wheel is often required to be turned. In practical application, the CBN emery wheel base member is the steel, and AF90 main shaft neck and connecting rod neck emery wheel weight are 50KG, AF110 flange emery wheel weight are 90KG, and the CBN emery wheel material is more fragile, in case produce in-process at transport upset emery wheel and collide with and will lead to whole emery wheel to scrap.

In the prior art, the replacement process of the grinding wheel is as follows: and taking out the grinding wheel from the grinding wheel box, installing the grinding wheel on the auxiliary support, and hoisting the grinding wheel by using the fixed grinding wheel hoisting tool to install the grinding wheel on the main shaft of the grinding machine. At present, the operation is carried and adjusted by the operator manpower, and the mode of this kind of manual handling not only wastes time and energy, still causes the incident very easily, has the emery wheel surface of colliding with and the emery wheel falls and injures operation workman's risk by a crashing object and emery wheel. Therefore, an installation tool for assisting in replacing the grinding wheel is urgently needed at present.

In order to solve the above problems in the prior art, some researchers have performed related optimization designs, and have obtained the following improvements:

1. multiple operators carry the grinding wheel together to share the gravity of the grinding wheel.

2. And carrying the grinding wheel by using an industrial robot.

3. Manufacturing a movable trolley with lifting and overturning functions, and carrying and installing a grinding wheel.

However, it should be noted that, the three improvements still have certain defects, and when the improvement scheme 1 is adopted, because the grinding wheel is in the shape of a smooth cylinder, a plurality of operators carry together the position which is not suitable for grabbing, and force application is inconvenient; and the cooperation of a plurality of people has uncoordinated risk, so that the grinding wheel is easy to slip off, and serious production safety accidents are caused. When adopting above-mentioned improvement scheme 2, the technical degree of difficulty that uses industrial robot transport emery wheel is higher, the cost is great. When the improved scheme 3 is adopted, the grinding wheel is heavy, the problems of stability and balancing of the center of the moving trolley are difficult to deal with along with the position movement of the grinding wheel in the installation process, and the moving trolley has the possibility of side turning.

Therefore, the technical scheme which can guarantee the safety of operators and accurately and effectively assist in installing the grinding wheel is still lacked at present, and in order to solve the problems in the prior art, the invention expects to obtain a hoisting installation tool for the grinding wheel, which is different from the prior art, the hoisting installation tool can assist in carrying and installing the grinding wheel by utilizing the lever principle, and has the advantages of simple structure, simple and convenient manufacturing and maintenance, good reliability and convenient use and operation; the hoisting installation tool is adopted to install the grinding wheel, so that the labor intensity of operators can be effectively reduced, the safety production can be guaranteed, the grinding wheel can be efficiently and safely hoisted and installed, the applicability is very wide, the hoisting installation tool can be effectively applied to all grinding machine grinding wheel hoisting installation occasions, and the hoisting installation tool has good popularization prospect and application value.
