Embodiment 1

[0006] Example 1: After the loading rack is pulled out, the compressed spring steel ball enters the hole, and there is no positioning effect. When the loading rack is sent inward, it reaches the fixed position of the guide rail, and the steel ball pops out and gets locked in the locking socket of the loading rack. Tight effect.

Description of the drawings:

[0007] 9 steel ball; 10, spring; 11, set screws.

Abstract

An air cylinder body assembly is a key component consisting of an air cylinder body and a crankcase, and is an assembling substrate for all mechanisms and systems of an internal combustion engine; more parts of the air cylinder body assembly are used as components of a crankshaft connecting rod mechanism, an air distributing mechanism, a supplying system, a cooling system and a lubricating system. All holes, all surfaces and parts between the holes and the surfaces on the air cylinder body assembly have higher requirements on size, shape and position tolerance, and the machining difficulty is great. Style machining of the air cylinder body assembly adopts general technical equipment; a machining technical process comprises four stages, namely rough machining and semi-finish machining of the air cylinder body and crankcase parts, finish machining of air cylinder body assembly components and fine machining of key parts. Key links of the whole technical process are selection of technical standards at all machining stages, machining of the key parts (a spindle hole, a cylinder hole and a camshaft hole) and calculation of important dimensions (coordinate dimension of hole centre distances of a spindle hole, a cam hole and an idle wheel hole). The invention provides an important part for the machining tooling for the cylinder body part holes, which is used for locking the position of a feeding rack and mainly comprises a steel ball 9, a spring 10 and a locking screw 11.

Description

Technical field [0001] Provide a simple and versatile tooling for solving the hole processing of various regular cylinder parts. Background technique [0002] The cylinder block assembly is a key component composed of the cylinder block and the crankcase. It is not only the assembly base of the various mechanisms and systems of the internal combustion engine, but also the crankshaft and connecting rod mechanism, the valve mechanism, the supply system, the cooling system and many parts of the internal combustion engine. An integral part of the lubrication system. Each hole, each surface and each other on the cylinder block assembly has high tolerance requirements for size, shape and position, and its processing is very difficult. The pattern processing of the cylinder block assembly uses general process equipment. The processing process can be divided into four stages: rough machining and semi-finishing of cylinder block and crankcase parts, finishing of cylinder block assembly c...
