Assembly machine for automatically installing engine cylinder head parts and installing method

Abstract

The invention discloses an assembly machine for automatically installing engine cylinder head parts and an installing method. The assembly machine comprises a support table, a spring compression device, cylinder head overturning devices and air valve detecting devices. The multiple cylinder head overturning devices are arranged on the support table, and each cylinder head overturning device can be overturned in the scope of 0 to 180 degrees. The spring compression device comprises a pressing plate and a pressing plate height lifting driving device; and the pressing plate is provided with valve bolt installation holes, and the inner diameters of all valve bolt installation holes are smaller than the outer diameter of a spring spiral ring but larger than the outer diameter of a valve bolt. Each air valve detecting device comprises an overturning frame, a disc and an air valve identification sensor. When the overturning frames are closed relative to the cylinder head overturning devices, the discs can seal and plug corresponding air valve sets, and the air valve identification sensors can detect whether neglected installation or air leakage occurs in air valves installed on cylinder heads or not. By means of the above structure and method, the structure is compact, the automatic degree is high, the usability and the reliability are good, and the beneficial effects of liberating the manpower and improving the production efficiency are achieved.

Description

technical field [0001] The invention relates to an automatic process equipment and assembly process of a cylinder head, in particular to an assembly machine and an installation method for automatic assembly of engine cylinder head parts. Background technique [0002] Assembly is an important process that finally determines product quality in mechanical manufacturing. Even if all qualified parts are improperly assembled, they often cannot form qualified products. Advanced assembly process requires advanced process equipment. The level of design and manufacture of process equipment is crucial to ensure high-efficiency production and high-quality products, and it is also a symbol of the level of automobile assembly technology. With the development of my country's automobile industry, my country has introduced a large number of advanced equipment from abroad, which has greatly improved the equipment level of the automobile industry; however, the domestic equipment manufacturing ...

Problems solved by technology

[0003] At present, the installation process of the cylinder head parts in the present invention, i.e. the valve, spring and valve plug, is still mainly manual assembly, and the assembly sequence is roughly as follows: first, the cylinder head is turned upside down from the initial posture by 180° with the aid of a sling, and then the valve is installed, and then the cylinder head is installed. Install the spring and the valve plug after reversely flipping 180° to the initial posture. The installation of the spring requires the operator to press the spring into the cylinder head with a special tooling fixture on the cylinder head, and then install the valve plug into the cylinder head. This traditional assembly Insufficient assembly accuracy, missing assembly or even rework often occur in the method, and at the same time, problems such as high labor intensity, low operation safety, low assembly efficiency, and backward assembly process are exposed.
