Automatic assembling machine for mounting studs of cylinder cover of diesel engine and assembling method

Abstract

The invention discloses an automatic assembling machine for mounting studs of a cylinder cover of a diesel engine and an assembling method. An automatic screening mechanism is used for screening, the second stud enters a first containing box of a four-station turnover device, the first containing box is driven by a rotary table to rotate by 90 degrees in the circumferential direction, and the first first stud enters a second containing box. A pneumatic chuck moves downwards to clamp the second stud; the second first stud and the third first stud enter a third containing box and a fourth containing box in sequence every time the rotary table rotates by 90 degrees; and four stud screwing devices clamp the second stud and the three first studs on a lower mold plate at the same time and mount the second stud and the three first studs in four corresponding stud holes in the cylinder cover at the same time, and assembling of the studs of the cylinder cover is completed. According to the automatic assembling machine, automatic feeding and feed of two types of studs can be achieved, the studs can be automatically screwed on the cylinder cover, and the assembling precision and efficiency of the cylinder cover can be improved.

Description

technical field [0001] The invention relates to the field of automatic assembly and production of diesel engines, in particular to an assembly machine and an assembly method suitable for automatic assembly of cylinder head studs of diesel engines. Background technique [0002] In the large-scale automatic production of diesel engines, the fully automatic assembly process of bolts on the cylinder head is often indispensable. It can not only improve productivity, reduce labor intensity of workers, but more importantly, it can ensure that the tightening torque of each bolt tends to Consistent, meet the design requirements, improve product assembly quality and overall performance. [0003] refer to figure 1 As shown in the structure of the diesel engine cylinder head 10, there are two cylinder head holes on the cylinder head 10, which are respectively the cylinder head hole 10-1 and the cylinder head hole 10-2, and these two cylinder head holes are distributed diagonally. Four...
