Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, and it is not used in restriction the utility model.
As shown in Figure 1, Figure 2, Fig. 3 and Fig. 4 is jointly shown, a kind of hand turning machine, including flange 1 and jackshaft 2.
The non-full circle of 1 outer profile of flange, about more than the 1/2 of circle, the part of missing is mainly used to save space, the side of flange 1
Edge is equipped with multiple bolts hole 13, and the center point of flange 1 is equipped with axis hole.Flange 1 is fixed close to a side surface of 2 first end of jackshaft
There is round positioning convex platform 11, reserved hole is covered after positioning convex platform 11 and engine and is cooperated, the position of locating flange 1.Flange 1 leans on
One side surface of 2 second end of nearly jackshaft is fixed with limit switch 5, and limit switch 5 is electrically connected to the control system.
Jackshaft 2 is slidably connected in axis hole, and the first end of jackshaft 2 is connected with driving gear 6 by key 7, and key 7 can be with
For flat key or spline, drive the medial surface of gear 6 by the shaft shoulder positioning on jackshaft 2, drive the lateral surface of gear 6 against
In on retaining ring 8, retaining ring 8 is sheathed on jackshaft 2, and the lateral surface of retaining ring 8 is limited by spring catch 9, and spring catch 9 is fixed on centre
On axis 2.
The second end of jackshaft 2 is equipped with spanner fit structure 21, and spanner fit structure 21 can be hexagonal prisms, or
Quadrangular perhaps triangular prism can also for hexagonal hole, square hole or equilateral triangle hole etc., as long as its can with pull
Hand cooperation can drive jackshaft 2 to rotate by spanner, when practical application, the preferably diameter hexagonal prisms that are 24mm.In
Between 2 second end of axis radially projecting major diameter section 22, the outside cylinder of major diameter section 22 are fixed at spanner fit structure 21
Face is equipped with screw thread, and major diameter section 22 is threaded with sleeve 4.
Wherein, driving gear 6 is located at the side of flange 1, and major diameter section 22, spanner fit structure 21 are located at the another of flange 1
Side is equipped with elastic component, the helical spring 3 being such as sheathed on jackshaft 2, it is also an option that rubber between major diameter section 22 and flange 1
Spring etc..
As Fig. 3 and Fig. 4 jointly shown in, when jiggering, engine is dead ship condition, is first fixed on flange 1 by bolt
It is covered after engine, then sleeve 4 is removed, push jackshaft 2 close to engine manually, drive gear 6 and engine to allow
Flywheel ring gear engagement rotates jackshaft 2 with common ratchet spanner, realizes equipment for engine jigger.Ratchet spanner can lengthen handle
Increase barring torque.
As Fig. 1 and Fig. 2 jointly shown in, after jiggering, remove ratchet spanner, helical spring 3 will drive gear 6 and centre
Axis 2 is pushed into designated position, at this point, driving gear 6 and engine flywheel ring gear normally disengage, sleeve 4 is threadedly connected to major diameter section
On 22, sleeve 4 is screwed onto be contacted with 1 end face of flange, at this point, again ensured that driving gear 6 and engine flywheel ring gear disengage, set
Cylinder 4 triggers limit switch 5, and control system jiggering locking signal releases, and engine can normally play vehicle.
Turning engine is directly anchored on diesel engine, and corresponding work and inoperative two states do not need to dismantle jiggering repeatedly
Machine improves jiggering efficiency, reduces the cost of engine.
Turning engine has double protection functions.If turning engine drives gear 6 and engine flywheel ring gear clamping stagnation, lead to spiral shell
Rotation spring 3 cannot disengage the two, can disengage the two by sleeve 4 and the cooperation of jackshaft 2 at this time.Limit switch 5 acts
Be engine rise vehicle necessary condition, and limit switch 5 act when, by self structure can ensure that turning engine driving gear 6 with
Engine flywheel ring gear disengages.The safety interlocking function of design can eliminate engine flywheel ring gear band Moving plate when engine plays vehicle
The security risk that vehicle device jackshaft 2 rapidly rotates.
The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field
The common knowledge of those of ordinary skill.The protection scope of the utility model is based on the contents of the claims, any to be based on this reality
The equivalent transformation carried out with novel technical inspiration, is also within the protection scope of the utility model.
