Embodiment Construction

[0015] The technical solutions of the present invention will be described in further detail below with reference to the drawings and specific embodiments.

[0016] As shown in Figures 1 and 2, an assembly method for finishing the cylinder block 3 of a diesel engine includes the steps of: designing and manufacturing a simulated cylinder head 2 according to the actual cylinder head; the cylinder block 3 is provided with a positioning round pin 5 , locate the round pin 6, align the base 4 with the cylinder block base installation device 7 on the cylinder block 3, position the round pin 5, and locate the round pin 6, so that the base 4 is installed into the cylinder block 3; use the simulated cylinder head 2 Connect the cylinder block 3 and the frame 4 for machining.

[0017] Among them, the simulated cylinder head 2 is designed according to the actual cylinder head (W3000 cylinder head), considering the assembly height, assembly torque, and stress generated by machining, and acco...

Abstract

The invention relates to an assembling method applied to fashioning a cylinder block of a diesel engine and assembling components thereof. The assembling method includes the following steps: a simulated cylinder head is designed and manufactured; the cylinder block is provided with a set pin, an engine seat aligns the set pin on the cylinder block so as to cause the engine seat to be installed in the cylinder block; the simulated cylinder head is connected with the cylinder block and the engine seat, and machining is carried out. The assembling components comprise a simulated cylinder head, a cylinder block and an engine seat, the simulated cylinder head, the cylinder block and the engine seat are connected in sequence. As the simulated cylinder head is designed and manufactured, in-and-out bolts are used for assembling the cylinder block, the simulated cylinder head and the engine seat for processing, thus overcoming the phenomenon that a spindle hole is deformed when the whole machine is assembled and processed, lowering the difficulty of processing and improving the precision and quality stability of the product.

Description

technical field [0001] The invention relates to an assembly method for finishing the cylinder body of a diesel engine and an assembly assembly using the method, in particular to an assembly method for connecting the cylinder body and the machine base of the diesel engine for finishing the cover. Background technique [0002] At present, when the cylinder block of the domestic diesel engine is finished at both ends, the crankcase or the shaft cover adopts the process method of screw hole connection of the cylinder block, instead of the diesel engine that connects the crankcase or the shaft cover through the cylinder head. In this way, the processing of the cylinder block is very difficult, and the uneven tightening force during the complete machine assembly and machining assembly will cause the deformation of the spindle hole, and the product accuracy and quality stability are difficult to guarantee, which cannot meet the processing requirements.
