Description

Technical Field

[0001] The present application relates to the technical field of vehicle axle grinding, and in particular to a device for grinding welding points at vehicle axle connections. Background Art

[0002] The automobile axle, also known as the axle, is connected to the frame (or load-bearing body) through the suspension, with wheels installed at both ends. The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road. The axle can be integral, like a huge barbell, supporting the body at both ends through the suspension system, so the integral axle is usually used with non-independent suspension; the axle can also be disconnected, like two umbrellas inserted on both sides of the body, and then each supports the body through the suspension system, so the disconnected axle is used with independent suspension.

[0003] Spot welding refers to a welding method that uses a cylindrical electrode to form a weld between the contact surfaces of two overlapping workpieces. Grinding is a surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing high hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. At present, when grinding the welds at the axle connection, it is inconvenient to position the axle, and the grinding head is fixed, which is not convenient for grinding curved welds, reducing the grinding quality of the axle. Therefore, in order to solve the above problems, we provide a device for grinding welds at axle connections. Utility Model Content
