The invention discloses an automatic assembling machine and method for an oil atomizer and an oil atomizing connecting pipe on a diesel engine air cylinder cover. The top end of the oil atomizer is placed in a first pneumatic chuck. The center line of the oil atomizer coincides with the center line of an oil atomizer installing hole of the air cylinder cover. The center line of an oil screw hole of the oil atomizer coincides with the center line of a positioning pin, a horizontal servo electric cylinder works, and the center line of the oil screw hole of the oil atomizer and the center line of the positioning pin are located on the same axis. An oil atomizer feeding mechanism drives the oil atomizer to be downwards pressed in the oil atomizer installing hole of the air cylinder cover. A vertical servo electric cylinder downwards moves till the center line of a second pneumatic chuck coincides with the center line of an oil atomizing connecting pipe installing hole of the air cylinder cover. The oil atomizing connecting pipe is placed on the second pneumatic chuck, and the left end of the oil atomizing connecting pipe is screwed into the oil atomizing connecting pipe installing hole of the air cylinder cover. By means of the automatic assembling machine and method for the oil atomizer and the oil atomizing connecting pipe on the diesel engine air cylinder cover, automatic alignment between the oil screw hole of the oil atomizer and the oil atomizing connecting pipe and automatic installation of the oil atomizer and the oil atomizing connecting pipe are achieved.
Description
technical field [0001] The invention relates to an automatic process equipment technology for a cylinder head of a diesel engine, in particular to an assembly machine for automatically installing a fuel injector and a fuel injection nozzle on the cylinder head of a diesel engine. Background technique [0002] As the last process in the product production process, assembly plays a vital role in the quality of the product. In the process of assembling a group of qualified products, if the assembly process is backward or improper, it often directly leads to a decline in product processing quality, and even rework and defective products due to unqualified assembly. [0003] refer to figure 1 As shown in the structure of the cylinder head 12 of the diesel engine, there are two vertical cylinder head positioning holes on the cylinder head 12, which are respectively the cylinder head positioning hole 12-1 and the cylinder head positioning hole 12-2, and the fuel injector installat...
