Disc type automobile casting surface treatment device

Abstract

The invention discloses a disc type automobile casting surface treatment device and belongs to the technical field of mechanical part machining. The device comprises an exhaust pipe fixedly mounted inthe middle of an upper end of an operation table, a casting absorption mechanism is mounted at a top end of the exhaust pipe, an end face grinding roller and a side face grinding roller are arrangedon a lifting circular truncated cone capable of moving up and down, the device can be suitable for polishing castings with different thicknesses, the side face grinding roller is arranged on one sideof the end face grinding roller, and the side face grinding roller synchronously rotates along with the end face grinding roller to grind a side face of a casting while the end face grinding roller rotates to grind the end face of the casting. The casting end face and side face synchronous grinding effect is effectively achieved, meanwhile, the side face grinding rollers symmetrically arranged onthe two sides of the end face grinding rollers can move in the horizontal direction, and thereby the casting side face treatment device can be suitable for side face treatment of castings of differentwidth specifications, and the application range of the treatment device is effectively expanded to a certain extent.

Description

technical field [0001] The invention relates to the technical field of mechanical parts processing, and more specifically relates to a surface treatment device for disc type automobile castings. Background technique [0002] In the automotive casting industry, many castings often have circular tube walls and cylindrical parts or the casting itself is a regular disc structure, such as the brake disc of a car. The brake disc is an important part of the car braking system. The brake disc, in simple terms, is a round disc. It also rotates when the car is moving. The brake calipers clamp the brake disc to generate braking force. When the brakes are applied That is, it clamps the brake disc to slow down or stop. [0003] Brake discs are usually formed by stamping and subsequently milled. Therefore, the surface and side corners are prone to produce more rough burrs. The existence of these burrs makes the surface of the brake disc rough and uneven. When used in equipment When it i...

Problems solved by technology

[0003] Brake discs are usually formed by stamping and subsequently milled. Therefore, the surface and side corners are prone to produce more rough burrs. The existence of these burrs makes the surface of the brake disc rough and uneven. When used in equipment When it is in the middle, it will often cause scratches and other damage to the equipment.

[0004] Therefore, after the stamping of the brake disc is completed, the burrs on its surface need to be polished. The upper end surface and the side of the brake disc casting need to be polished and polished. The upper end surface and the side surface are treated, so the grinding of the brake disc often needs to be carried out step by step, the operation is more troublesome, it is difficult to perform the grinding operation simultaneously, and the surface treatment efficiency of the casting needs to be improved; in addition, some existing surface treatment devices are often only suitable for the same diameter. Large and small castings have poor operational flexibility, so the scope of application needs to be improved
