Abstract
The utility model relates to a testing fixture applicable to the machining detection, particularly to an apparatus for verifying the position accuracy of the belt pulley and flywheel. The apparatus is characterized by comprising a locating shaft and a pedestal, wherein one end of the locating shaft is installed upon the end surface of the pedestal while the axle diameter of the other end of the locating shaft is matched to the bore diameter of the to-be-detected component. The apparatus of the utility model features simple structure, wide adaptability, convenient operation, good examination quality, and high efficiency.
Description
Technical field
Cubing during the machining that relates to the utility model detects, particularly a kind of belt pulley of diesel engine and flywheel position degree verifying attachment.
Background technology
The flywheel of diesel engine looks it is the cast iron disk of a heaviness, but it plays very large effect: 1) make machine operation even, rotation steadily.The flywheel High Rotation Speed because inertia effect can be preserved energy, also can be emitted energy, overcomes the resistance of motion, makes engine running steady.When overspeed operation, it can be preserved energy, makes its slow speed-raising, avoids suddenly running up and causes and have little time to handle and out of hand; When low-speed running, energy is discharged, make its slowly reduction of speed, avoiding suddenly, low speed causes stopping.2) assist to start.Diesel engine is compression ignition, and during startup, the rocking-turn flywheel makes it have startup inertia at first fast, helps piston to cross compression top center, reaches the startup purpose.3) the convenient fuel supply advance angle of proofreading and correct.The diesel engine of various models has different fuel supply advance angles, if fuel supply advance angle is excessive, the diesel oil that sprays into is burnt in advance, rough running, and cylinder has knock, and diesel engine power descends, and easily reverses when starting larry; And fuel supply advance angle is too small, then can difficulty in starting, incomplete combustion, excess Temperature, oil consumption increase, gas outlet over-emitting black exhaust and power decline.4) the convenient valve clearance of adjusting.The valve clearance is too small, part expanded by heating when elongation, causes that valve-closing is tight and leak gas that incomplete combustion burns out valve and valve seating, and the phenomenon of top land and valve collision also might occur; The valve clearance is excessive, valve is held early late closed, and opens and shortens perdurability, and valve opening reduces, and causes that air inlet is not enough, and row is unclean for waste gas, and the bump of aggravation valve and rocking arm increases its wearing and tearing.The transmission of flywheel realizes by belt pulley, and flywheel and belt pulley be connected with three mounting holes, to be directly installed on the flywheel with belt pulley to check before, be difficult to the correct specification product of judging, to making the product non-interchangeability, often run into the embarrassment that the belt pulley that sends out can't assemble, had a strong impact on the image of company, caused very large loss to company.
Summary of the invention
The purpose of this utility model namely is to provide a kind of and can overcomes deficiency, belt pulley simple in structure and the flywheel position degree verifying attachment that prior art exists.
To achieve these goals, flywheel position degree verifying attachment of the present utility model is characterized in: comprise locating shaft, base and handle, handle is connected with base, one end of locating shaft is installed on the end face of base, and the size of the other end diameter of axle matches with the aperture of detected part.
Above-described locating shaft is some.
Compared with prior art, the beneficial effect of this belt pulley and flywheel position degree verifying attachment is:
The utility model is to adopt an end of locating shaft to be installed on the end face of base, the size of the other end diameter of axle matches with the aperture of detected part, having solved original employing belt pulley is directly installed on the flywheel and checks, to making the product non-interchangeability, often run into the belt pulley that sends out and to assemble existing problem, three mounting holes when taking full advantage of flywheel and being connected with belt pulley, position degree to belt pulley and flywheel is tested, the rate of being up to the standards has reached 100%, has improved the interchangeability of product, has simple in structure, wide adaptability, easy to operate, quality inspection is good, the efficient advantages of higher.The utility model can also be extended to the check for other rotary parts.

Embodiment
Below in conjunction with drawings and Examples structure of the present utility model is described.
Shown in accompanying drawing 1～2, belt pulley of the present utility model and flywheel position degree verifying attachment, comprise locating shaft 1, base 2 and handle 3, handle 3 is connected connection with base, one end of locating shaft 1 is installed on the end face of base 2, the size of the other end diameter of axle matches with the aperture of detected part, and described locating shaft 1 is some.
In Dec, 2011, belt pulley and the flywheel position degree verifying attachment of inventor's design shown in accompanying drawing 3, are used for the position degree of check YC195 diesel engine flywheel 4 and belt pulley connecting hole.This verifying attachment comprises three locating shafts 1, base 2 and handle 3, and an end of each locating shaft 1 is distributed on the end face of base 2, and the size of the other end diameter of axle is identical with the aperture of detected diesel engine flywheel 4.During check, first this verifying attachment and diesel engine flywheel 4 are cleaned up, prevent that impurity from entering the position that part cooperates, the axle head of each locating shaft 1 is aimed at respectively in three holes of YC195 diesel engine flywheel 4, slowly be inserted in, until the end face of the upper surface of YC195 diesel engine flywheel 4 and base 2 is fitted, the position degree that these 4 three holes of YC195 diesel engine flywheel are described is qualified, otherwise, if three holes of 195S diesel engine flywheel 4 can not be inserted in three locating shafts 1, judge that then the position degree of this YC195 diesel engine flywheel 4 is defective.Since four months, the position degree of customer response YC195 diesel engine flywheel 4 is accurate, installs easily.
In Dec, 2011, belt pulley and the flywheel position degree verifying attachment of inventor's design shown in accompanying drawing 4, are used for the position degree of check YC195 diesel engine belt pulley 5 screws.This verifying attachment comprises that three locating shafts 1 and base 2(unload handle 3), an end of each locating shaft 1 is distributed on the end face of base 2, and the size of the other end diameter of axle is identical with the internal diameter of detected diesel engine belt pulley 5 screws.During check, first this verifying attachment and diesel engine belt pulley 5 are cleaned up, prevent that impurity from entering the position that part cooperates, three screws of YC195 diesel engine belt pulley 5 are aimed at the axle head of each locating shaft 1, slowly be inserted in, until the end face of the lower surface of diesel engine belt pulley 5 and base 2 is fitted, the position degree that these YC195 diesel engine belt pulley 5 screws are described is qualified, otherwise, if three screws of diesel engine belt pulley 5 can not be inserted in three locating shafts 1, judge that then the position degree of these diesel engine belt pulley 5 screws is defective.Since four months, customers' responsiveness YC195 diesel engine flywheel is accurate with cooperating of diesel engine belt pulley 5, has reached interchangeability, installs easily.
