Air detection tool for engine cylinder block machining

Abstract

The invention relates to an air detection tool for engine cylinder block machining. The air detection tool comprises a bottom plate, a clamping device, a positioning block, a positioning pin and a supporting device. A to-be-machined cylinder block is supported by the supporting device. The cylinder block is pressed on the supporting device tightly from the left end and the right end of the cylinder block through the clamping device. The positioning block is arranged on the bottom plate. The positioning pin is arranged on the positioning block and corresponds to a positioning hole in the cylinder block. An airtightness detection block is arranged on the bottom plate. An air hole is formed in the airtightness detection block. The top face of the airtightness detection block corresponds to the positioning face of the cylinder block. The air hole in the airtightness detection block is connected with a hole channel formed in the bottom plate. The hole channel is connected with an air sourceand a control valve through a pipeline. A pressure sensor is arranged in the hole channel. The air detection tool is simple in structure, convenient to use, low in cost and stable in structure, whether the cylinder block is positioned and clamped accurately can be accurately and rapidly determined, thus, machining errors and mistakes caused by positioning problems are avoided, the machining precision is ensured, and the machining quality of the cylinder block is ensured, so that the rejection rate is lowered, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of equipment for processing engine cylinder blocks, and in particular relates to an air detection tool for processing engine cylinder blocks. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy, and the engine block is an important actuator in the components. Engine When the cylinder is processed online, corresponding tooling is required to fix the cylinder. Generally, the placement of the cylinder needs to be controlled manually. The cylinder is heavy and has a complex structure. It is difficult to quickly determine whether the positioning surface fits and whether the position is appropriate when placing it.

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy, and the engine block is an important actuator in the components. Engine When the cylinder is processed online, corresponding tooling is required to fix the cylinder. Generally, the placement of the cylinder needs to be controlled manually. The cylinder is heavy and has a complex structure. It is difficult to quickly determine whether the positioning surface fits and whether the position is appropriate when placing it. At present, this problem is particularly prominent in the automatic production line. During the processing of the automatic production line, personnel cannot approach the equipment. The clamping of the cylinder is done by robots. The processing personnel cannot directly control the placement of the cylinder and cannot determine the placement of the cylinder. Whether it is suitable, whether the positioning surface is accurately positioned, and if the positioning of the cylinder body is not accurate, it will lead to increased processing errors, or even processing errors, resulting in increased scrap rate and low cylinder processing efficiency
