Specific embodiment
As shown in the picture: the measuring device of diesel engine top dead centre mainly includes crank handle 1, pointer 6, axle sleeve 3, angle table
Disk 2；Crank handle 1 is integrally formed, left and right symmetrical, realizes uniform stressed；The arc-shaped boss-shaped in 1 top of crank handle,
Front and rear end is in planar design, and the arc-shaped design in left and right side improves comfort；The upper surface of crank handle 1 is plane, benefit
In being provided with fixation hole 11 in drilling, the upper surface；1 lower part of crank handle is in sleeve-shaped, 1 lower part of crank handle
It is provided with axle sleeve mounting hole, is provided with threaded hole 12 on the circumference hole wall of the axle sleeve mounting hole；1 top of crank handle is also set up
There is pointer mounting groove 13, pointer 6 is integrated to crank handle top by pointer mounting groove 13 and/or fixation hole 11, passes through finger
Needle fixing screws 5 are fixed；The pointer is in " 7 " font, is integrally formed；In the pointer fixed plate 62 on 6 top of pointer
It is provided with pointer fixation hole 61, is that pointer observes part 63 on the right side of pointer 6.It is installed by the axle sleeve 1 lower part of crank handle
Hole and 3 rear gap of axle sleeve cooperate；Keyway 31 and crank handle locking hole 32 are provided on the circumferential side wall of axle sleeve 3；Axis
Set 3 is carried out with crankshaft front end axis 4 by key 7 circumferentially fixed.The locking of the crank handle 1 and axle sleeve 3 is to pass through crank handle
Lock-screw 8 simultaneously the crank handle locking hole 32 on the threaded hole 12 and axle sleeve 3 on precession crank handle and reach.Hand
Axle sleeve 3 is set between handle 1 and crankshaft front end axis 4, the abrasion of crank handle 1 can be reduced during exercise, and axle sleeve 3 is convenient for system
It makes and replaces.Corresponding axle sleeve 3 can be arranged according to the drift angle of crankshaft of diesel engine pitman shaft and crankshaft front end shaft key groove simultaneously, that is, changed
Become the positional relationship of the crank handle locking hole 32 on axle sleeve 3.The angle dial plate 2 is integrally formed；2 lower part of angle dial plate is in circle
Ring-type, the annulus lower part of the angle dial plate 2 are provided with a protrusion, and angle dial plate 2, dimension can be lived by this protrusion rotation or surely
The vertical position for holding angle dial plate 2 is prevented when crank handle 1 moves, and angle dial plate 2 also and then moves.The setting of annulus top
There is a vertical observation panel 23, can whether in a vertical position by this observation panel viewing angle dial plate 2, i.e., observation panel is in vertical
