Abstract
The invention provides a diesel engine coupling joint assembling position detecting method. The threaded end of an inspection device is arranged in a cylinder sleeve through a cylinder cover oil sprayer hole of a cylinder and connected to a technological threaded hole at the middle position at the top of a piston, a dial gage probe is arranged at a hexagonal platform end of the inspection device, a jigger drives a crankshaft to rotate, a top dead center of the cylinder piston is found by observing numerical reading of the dial gage, and whether a pointer on a gear disc points to a stipulated scale number or not is observed. If the pointer points to the stipulated scale number, coupling joint assembly and crankshaft installation are proved to be correct; and if the pointer does not point to the stipulated scale number, coupling joint assembly and crankshaft installation are proved to be incorrect. The diesel engine coupling joint assembling position detecting method is simple in operation, time-saving and labor-saving.
Description
Technical field
The invention belongs to Diesel Engine Technique Field, relate in particular to a kind of diesel engine shaft coupling rigging position detection method.
Background technology
In the process of diesel engine bench test, need to carry out every inspection to diesel engine, whether correct comprising the position of shaft coupling assembling.The shaft coupling assembling comes location and installation to arrive crankshaft output end by a resilient key of crankshaft end-face, if there is deviation the position of resilient key on the bent axle, will cause the scale value of toothed disc and crankshaft rotating angle value to not going up, thereby cause the incorrect of diesel engine test data.Need to use spanner that the shaft coupling assembling is pulled down, check by metering whether the position of bent axle resilient key is correct again.This kind mode need to be pulled down the shaft coupling assembling, and workload is larger.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of operation not only simple and convenient but also can guarantee the diesel engine shaft coupling rigging position detection method of measuring accuracy.
The object of the present invention is achieved like this: a kind of diesel engine shaft coupling rigging position detection method is characterized in that taking the following step:
A. make cubing, this cubing is made of metallic rod body, nylon block and plastic casing, and metallic rod body runs through total, and an end is helicitic texture, and the other end is six side's platforms, and cover has nylon block and plastic casing on the body of rod;
B. jiggering turning crankshaft makes the piston of selected cylinder number near top dead centre;
C. the cylinder cap fuel injector hole by this cylinder number with under the thread end of cubing in cylinder jacket, be connected on the craft thread hole in top land centre position, with the dial gauge probe place cubing six side's platform ends on;
D. slow jiggering turning crankshaft is looked into the dial gauge reading by sight and is found this cylinder piston top dead center;
E. observe pointer on the toothed disc whether on regulation scale numerical value, if on prescribed degree numerical value, illustrate that the shaft coupling assembling is errorless with crankshaft installed; If not on regulation scale numerical value, explanation is that the shaft coupling assembling is incorrect with crankshaft installed.
Technical scheme of the present invention has been finished detection to diesel engine shaft coupling assembling and bent axle by a kind of simple detection means, and is simple to operate, time saving and energy saving.Its cubing can also be used as the piston clamper when the shipping power packages is assembled.
Description of drawings
Fig. 1 is the used cubing synoptic diagram of the embodiment of the invention.
Fig. 2 is that the diesel engine shaft coupling rigging position of the embodiment of the invention detects synoptic diagram
Number in the figure: 1-six side's platforms, 2-nylon block, 3-plastic jacket, 4-screw thread, 5-dial gauge, 6-cubing, 7-cylinder head, 8-cylinder jacket, 9-piston rod group.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Referring to Fig. 1 and Fig. 2 in detail, the diesel engine shaft coupling rigging position detection method of present embodiment is described in detail.The used cubing of present embodiment is made of metallic rod body, nylon block and plastic casing.Metallic rod body runs through total, and head machining screw 4 can directly be screwed into top land, and afterbody is processed into six side's platforms 1, plays for convenience detach and the measurement effect.Middle nylon block 2 is designed to can be following in cylinder head, plays the effect of stably measured instrument.Plastic casing 3 is installed in nylon block 2 bottoms, and whole metallic rod body is entangled, and is inner with the protection cylinder head, prevents from damaging.
During detection, first jiggering turning crankshaft makes the piston 9 of selected cylinder number near top dead centre.Then, cylinder head 7 oil injector holes by this cylinder number in cylinder jacket 8, are connected to the thread end of cubing 64 times on the craft thread hole of piston 9 crown center positions, with the probe of dial gauge 5 place cubing 6 six side's platform ends on.Slow jiggering turning crankshaft, the reading of looking into dial gauge 5 by sight finds this cylinder piston top dead center.Whether the pointer of observing on the toothed disc is being stipulated on the scale numerical value: if on prescribed degree numerical value, illustrate that the shaft coupling assembling is errorless with crankshaft installed; If not on regulation scale numerical value, explanation is that the shaft coupling assembling is incorrect with crankshaft installed, common this situation need to be pulled down the shaft coupling assembling and re-assembly owing to crankshaft output end resilient key position has deviation to cause.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
