Problems solved by technology

[0003] 1. One person can only clean one water jacket hole at a time with a portable air shovel, but one cylinder needs to clean multiple water jacket holes, the cleaning efficiency is low, and the production efficiency can only be met by increasing labor;
[0004] 2. Due to different cleaning methods and angles, the degree of tightness of the residual sand in the inner cavity of the water jacket is different, and the shovel head will break during the cleaning process, resulting in casting waste

Abstract

The invention discloses a device and method for pre-cleaning the residual sand in the inner cavity of the water jacket of the cylinder body. The device uses the positioning pin of the device itself to locate the cylinder mouth of the cylinder body blank. After the positioning is completed, it uses manpower and the gravity of the device itself. The vibration of the vibrator makes the shovel head enter the inner cavity of the water jacket of the cylinder blank to clean the residual sand. When the height limit column on the device touches the top surface of the cylinder blank, it means that the sand cleaning is completed and the vibrator stops working , the device leaves the cylinder body blank, and the device is reset. Using the device and method for pre-cleaning the residual sand in the inner cavity of the water jacket of the cylinder body of the present invention, the cleaning efficiency of the residual sand in the inner cavity of the water jacket of the cylinder body blank is improved, and the quality of the pre-cleaning is improved. Cleaning The process is safe and the operation is simple.

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...
