Problems solved by technology

[0003] The rough boring of the cylinder liner is the first process of the cylinder liner processing. Due to the irregular shape of the cylinder liner, during the rough boring process of the cylinder liner, the existing fixture is unstable to the cylinder liner, which may easily cause the boring deviation. The boring deviation not only causes the cylinder liner The unevenness of the processing volume inside and outside the blank will easily cause waste products such as slag holes and sand holes, and will affect the final analysis of the reasons for the waste cylinder liner

Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] During specific implementation, combined with figure 1 , a jig for rough boring cylinder liners, including a base 1, tooth ring 2, rubber ring 3, positioning ring 4, cover plate 5, cylinder liner 6, sealing ring 7, pressure head 8. The base 1 is provided with a groove, and the tooth ring 2, the rubber ring 3 and the positioning ring 4 are installed in the groove of the base. The tooth ring 2 is installed at the bottom of the groove. The function of the tooth ring is to increase friction to prevent the cylinder liner blank from rotating. The inner and outer sides of the upper part of the tooth ring are respectively installed with a positioning ring 4 and an apron 3. A cylinder liner 6 is installed on the base 1. And link to each other wit...

Abstract

The invention discloses a fixture for cylinder jacket rough boring. The fixture comprises a base, a tooth ring, a rubber ring, a positioning ring and a pressing head; the base is provided with a groove; the tooth ring, the rubber ring and the positioning ring are mounted in the groove; the tooth ring is mounted at the bottom of the groove; the positioning ring and the rubber ring are respectively mounted on the inner and outer sides of the upper part of the tooth ring; a cylinder jacket is mounted on the base, and is connected with the positioning ring; and the pressing head is mounted at the upper part of the cylinder jacket. The fixture for cylinder jacket rough boring is simple in structure and convenient to manufacture, maintain and use, reduces the rejection rate in cylinder jacket rough boring, and improves the economic benefit of enterprises.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a fixture for rough boring of cylinder sleeves. Background technique [0002] The cylinder liner is the abbreviation of the cylinder liner. It is inlaid in the cylinder barrel of the cylinder block and forms the combustion chamber together with the piston and the cylinder head. Cylinder liners are divided into two categories: dry cylinder liners and wet cylinder liners. The cylinder liner whose back side does not contact the cooling water is called a dry cylinder liner, and the cylinder liner whose back side is in contact with cooling water is a wet cylinder liner. The dry cylinder liner has a thinner thickness, simple structure and convenient processing. The wet cylinder liner is in direct contact with the cooling water, so it is beneficial to the cooling of the engine, and is conducive to the miniaturization and weight reduction of the engine. [0003] The rough boring of t...
