Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described in detail, it is to be understood that this
The protection domain of invention is not limited by detailed description of the invention.
As shown in Figures 1 and 2, the attaching/detaching apparatus of a kind of engine valve spring of the present invention has one admittedly
Determining assembly, fixation kit is used for fixing on the cylinder end face of electromotor, and is disassembling and assembling engine valve bullet
Spring provides and supports.Specifically, in the present embodiment, fixation kit includes support column 2, revolving bed 3 and slides
Swing arm 5, support column 2 lower end is provided with stud 1, and support column 2 is tightened in by stud 1 and starts
In the bolt hole of machine cylinder end face.Revolving bed 3 is sleeve-shaped, and revolving bed 3 is spindle rotationally arranged in and props up
The upper end of dagger 2, has horizontal cut for installing trip bolt 4, trip bolt in revolving bed 3 upper end
4 upper ends being screwed into support column 2, travelling arm 5 is slidably located at the upper end of revolving bed 4, and revolving bed 4 exists
On support column 2, axial rotation is used for determining that travelling arm 5 aligns with engine valve spring, and by fastening
Revolving bed 4 is tightened together by screw 4 with support column 2.
It addition, be fixedly installed pinion stand 6 in one end of travelling arm 5, pinion stand 6 installed and drives gear
8 and ratch bar 7, drive gear 8 to be arranged on pinion stand 6, at gear shaft 12 by gear shaft 12
One end arranges the rocking bar 13 that gear shaft 12 rotates, and drives gear 8 to rotate together with gear shaft 12,
Gear 8 is driven to engage with ratch bar 7, manually rocking bar 13, drive gear 8 can drive ratch bar
7 move up and down, and ratch bar 7 is used for extruding engine valve spring and then dismantling it.
As shown in Figures 3 and 4, specifically, pinion stand 6 is square opening square with up/down perforation
Block, drives gear 8 to be arranged on square opening side by gear shaft 12, and gear shaft 12 is by two lockings
