Abstract

The invention discloses a device and method for precleaning residual sand in an inner cavity of a water jacket of a cylinder. The device and a cylinder opening of a cylinder blank are located by utilizing self locating pins of the device, shovel heads enter the inner cavity of the water jacket of the cylinder blank to clean residual sand by utilizing manpower and self-gravity of the device as well as the vibration of a piston vibrator after location is finished, and when a height limiting post on the device is in contact with the top surface of the cylinder blank, it shows that sand cleaning is finished, the vibrator stops working, the device leaves from the cylinder blank, and the device is reset. By using the device and method for precleaning residual sand in the inner cavity of the water jacket of the cylinder, the cleaning efficiency of the residual sand in the inner cavity of the water jacket of the cylinder blank is increased, the precleaning quality is improved, the cleaning process is safe, and the device and method are simple in operation.

Description

technical field [0001] The invention relates to the field of casting of automobile engine cylinder blocks, in particular to a device and method for pre-cleaning residual sand in the cavity of a water jacket of a cylinder block. Background technique [0002] In the field of automobile engine cylinder block casting, it is necessary to perform shot blasting on the engine block blank. After shot blasting, it is necessary to ensure that the cleanliness of the inner cavity of the water jacket meets the technical requirements. The current method is to use the cylinder block casting before entering the shot blasting machine. Manually use the wind shovel to vibrate and clean the residual sand in the inner cavity of the water jacket, so that the residual sand in the inner cavity of the water jacket of the cylinder body can be loosened, which is convenient to improve the later shot blasting effect and meet the cleanliness requirements of the cylinder body after shot blasting. At presen...
