The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.
As shown in Figures 1 and 2, the attaching/detaching apparatus of a kind of engine valve spring of the present invention has a fixation kit, and fixation kit is used for fixing on the cylinder end face of engine, and provides support for disassembling and assembling engine valve spring.Particularly, in the present embodiment, fixation kit comprises support column 2, revolving bed 3 and travelling arm 5, and support column 2 lower ends are provided with stud 1, and support column 2 is tightened in the bolt hole of cylinder end face by stud 1.Revolving bed 3 is sleeve-shaped, the rotating upper end that is arranged on support column 2 of revolving bed 3, in revolving bed 3 upper ends, there is horizontal cut and be used for installing trip bolt 4, trip bolt 4 is screwed into the upper end of support column 2, travelling arm 5 is slidably located at the upper end of revolving bed 4, revolving bed 4 axial rotation on support column 2 is used for determining that travelling arm 5 and engine valve spring align, and by trip bolt 4, revolving bed 4 is tightened together with support column 2.
In addition, in one end of travelling arm 5, be fixedly installed pinion stand 6, driven wheel 8 and ratch bar 7 are installed on pinion stand 6, driven wheel 8 is arranged on pinion stand 6 by gear shaft 12, and the rocking bar 13 that gear shaft 12 is rotated is set in one end of gear shaft 12, and driven wheel 8 rotates together with gear shaft 12, driven wheel 8 engages with ratch bar 7, by manual rocking bar 13, driven wheel 8 can move up and down by driving gear bar strip 7, and ratch bar 7 is used for pushing engine valve spring and then it is dismantled.
As shown in Figures 3 and 4, particularly, pinion stand 6 is the square block with the square opening of up/down perforation, driven wheel 8 is arranged on square opening one side by gear shaft 12, gear shaft 12 is locked by two locking nuts 11, driven wheel 8 is fixed on gear shaft 12, and manual actuation rocking bar 13 gear shaft 12 drive driven wheel 8 to rotate, and ratch bar 7 is inserted in square opening opposite side and engages with driven wheel 8.In order to carry out locked to ratch bar 7, on the end face of the lower end of pinion stand 6, be provided with the lock banking stop 9 that can rotate, one end of lock banking stop 9 can snap in the slot of ratch bar 7, and ratch bar 7 can move down smoothly, is subject to the spacing and then locked of lock banking stop 9 while oppositely moving.
