Cylinder cover combustion chamber height automatic measuring device

Abstract

The invention discloses an automatic cylinder cover combustion chamber height measuring device. The device comprises a tool base, wherein a lifting power source is installed in the tool base, a lifting plate is installed on the lifting power source in a mode of penetrating through the tool base, side edge control power sources are installed on the tool base and located on a front side edge and a rear side edge of the lifting plate, the tool base is provided with a longitudinal limiting block, a transverse limiting block, a front-back limiting block and a displacement sensor, the longitudinal limiting block, the transverse limiting block, the front-back limiting block and the displacement sensor are arranged in a triangular mode, the displacement sensor is connected with a sensor longitudinal movement control power source, and the lifting plate is provided with a plurality of through holes corresponding to the longitudinal limiting block, the transverse limiting block, the front-back limiting block and the displacement sensor. The device is advantaged in that the longitudinal limiting block, the transverse limiting block and the front-back limiting block are used for positioning thereference position of the cylinder cover, and the displacement sensor makes contact with a combustion chamber measuring point of the cylinder cover to judge whether the height of the combustion chamber of the cylinder cover is qualified or not. The device has advantages of convenient program operation, high measurement efficiency, low cost investment and the like.

Description

technical field [0001] The invention relates to height measuring equipment, in particular to a measuring device for the height of a combustion chamber of a cylinder head. Background technique [0002] The height dimension of the cylinder head combustion chamber is a key characteristic dimension on the cylinder head, which can directly affect the performance of the automobile engine. As an important dimension, it needs 100% inspection to ensure that all products provided to customers are qualified products. The traditional method of detecting the height of the combustion chamber of the cylinder head is to use a CMM for programming measurement. The measurement cycle of a product is about 180 seconds. For companies that produce cylinder heads in large quantities every day, all use CMM. Machine measurement is unrealistic, the measurement efficiency is too slow, and the three-coordinate detection resources are seriously wasted and occupied. SUMMARY OF THE INVENTION [0003] Th...

Problems solved by technology

The traditional method of detecting the height of the cylinder head combustion chamber is to use a three-coordinate measuring machine for programming measurement. The cycle time for measuring a product is about 180 seconds. For companies that produce cylinder heads in large quantities every day, all of them use three-coordinate measurement. Machine measurement is unrealistic, measurement efficiency is too slow, serious waste and occupation of three-coordinate detection resources
