Description

Technical Field

[0001] The invention relates to the technical field of fine grinding of a front axle I-beam, and in particular to a fine grinding device and process for a front axle I-beam. Background Art

[0002] The I-beam of the front axle is formed by integral die forging, and its cross section is in the shape of an "I", so it is called an "I-beam". The I-beam is forged as one piece with the front leaf spring seat. To avoid interference with the engine oil pan, there is a downward drop in the middle. The material of the I-beam is generally made of carbon steel or Cr steel and is modulated. During design, the weight is reduced as much as possible while ensuring the strength. The front axle, as the main part, is generally made of medium carbon steel through die forging and heat treatment. To improve the torsional strength, there is a thickened part in the shape of a fist near each end of the front axle, with a through hole in it, and the kingpin is inserted into this hole. The middle part is bent downward into a concave shape, the purpose of which is to lower the position of the engine, thereby lowering the center of mass of the car; expanding the driver's field of vision; and reducing the angle between the drive shaft and the transmission output shaft.

[0003] In order to increase the service life of the I-beam and improve the use effect of the I-beam, it is necessary to perform fine grinding on the surface of the workpiece after die forging so as to paint on its surface. During the fine grinding process, the workpiece is generally required to be fixed, which makes it difficult to grind the fixed part of the workpiece, and there are grinding dead corners. In addition, due to the irregular surface of the workpiece, it is impossible to use traditional grinding methods for grinding, and the grinding is difficult. If it is only done manually, the grinding efficiency is low, and it cannot be guaranteed that the surface of the workpiece is completely polished. In addition, the degree of grinding is controlled by the workers, and it is very easy for some areas to be polished to a large extent, resulting in the finished size of the I-beam not meeting the standards. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a front axle I-beam fine grinding processing device and process.

[0015] S1. Positioning the workpiece: First, insert the molded part vertically into the feed ring;

[0016] S2, initial grinding: Introduce gas into the rubber airbag ring to make the grinding part and the molded part surface close to each other for initial grinding;

[0017] S3, repeated grinding: restore the state of the rubber airbag ring, drive the rubber airbag ring to rotate through the rotating frame, and repeat S2;

The magnetic blocks of different volumes make the magnetic repulsion forces on the grinding ball at different positions different, thereby preventing the grinding ball from being subjected to the same magnetic repulsion force and thus being balanced in force at a certain position and no longer rolling.

[0021] 3. The grinding unit provided in the present invention allows the air driven by the vacuum cleaner to circulate smoothly through the exhaust port, prevents metal chips from being discharged from the collection box through the filter cotton, cleans the thicker metal chip layer on the surface of the grinding ball through the sweeping ring brush, and scrapes off the metal chips on the surface of the grinding ball that are difficult to be cleaned by the sweeping ring brush through the annular scraping groove.

The grinding unit provided in the present invention supports the inside of the rubber airbag ring through a cylindrical spring to prevent the rubber airbag ring from sticking due to long-term non-use, and prevents the cylindrical spring from scratching the inside of the rubber airbag ring through a rubber pad. The exhaust gas is further guided by a guide wheel and rotates under the drive of the gas, thereby accelerating the flow of the gas. BRIEF DESCRIPTION OF THE DRAWINGS
