Abstract
The invention discloses a pulley groove alignment metric inspection tool of a poly V-belt gear train of an engine. The pulley groove alignment metric inspection tool of the poly V-belt gear train of the engine comprises a support and a laser electric torch fixedly arranged at the top of the support; and a convex rib crossly arranged on a reference pulley is arranged at the bottom of the support. The laser electric torch detects the alignment metric of a pulley groove of the poly V-belt gear train of the engine, so that the detection precision is high and the operation is simple.
Description
Technical field
The present invention relates to engine art, particularly a kind of engine polywedge bet train pulley groove degree of registration instruments of inspection.
Background technology
Before engine dispatched from the factory at present, the degree of registration of wheel train belt race needed to detect, and with the high performance operation of assurance train, and the detection of the degree of registration of pulley groove mainly detects by range estimation or three-coordinate instrument.Wherein, the precision of range estimation belt pulley degree of registration is relatively poor; And three-coordinates measuring machine refers in a hexahedral spatial dimension, can show the instrument of the measurement capabilities such as geometric configuration, length and circumference graduation, is called again three coordinate measuring machine or three-dimensional amount bed.Three-coordinates measuring machine again definable " a kind of have can make the detector that three directions move; can be mobile at three orthogonal guide rails; this detector is with mode transmitting signals such as contact or noncontacts; the displacement measurement system of three axles (such as grating scale) calculates the each point (x; y, z) of workpiece and the instrument that various functions is measured through data processor or computing machine etc. ".But using the three-coordinate instrument detection is a very accurate and time-consuming measures of quantization mode, greatly affects production efficiency, and belt train degree of registration is also unnecessary all carries out the precise quantification three-dimensional coordinates measurement to each and engine dispatches from the factory.
Summary of the invention
The technical matters that the present invention solves provides a kind of accuracy of detection engine polywedge bet train pulley groove degree of registration instruments of inspection high, simple to operate.
For achieving the above object, the invention provides a kind of engine polywedge bet train pulley groove degree of registration instruments of inspection, comprising: bearing and the laser torch that is fixed on the bearing top, the bottom of bearing has the convex tendon that is crossed on the benchmark belt pulley.
Further, convex tendon is two, and spacing is the odd number wheel slot pitch more than three or three of benchmark belt pulley, and equidistant apart from the right and left edge of rest base, and the electroluminescent lamp of laser torch is positioned at the middle of two described convex tendons.
Further, an end of bearing has breach, and breach is positioned at the centre of two convex tendons.
Further, bearing is saddle-shape.
Further, laser torch is installed on the bearing by fixed card, and fixed card is arc, the middle part draw-in groove interference fit of electric torch casing and fixed card arc, and the two ends of fixed card arc are fixed to the top of bearing by screw.
According to technical scheme of the present invention, owing to adopted laser torch to detect engine polywedge bet train pulley groove degree of registration, so that accuracy of detection is high, simple to operate.
Description of drawings
Fig. 1 is the perspective view according to the engine polywedge bet train pulley groove degree of registration instruments of inspection of the present invention;
Fig. 2 is the assembly structure schematic diagram according to the engine polywedge bet train pulley groove degree of registration instruments of inspection of the present invention;
Fig. 3 and Fig. 4 are overlooking and schematic side view that the engine polywedge bet train pulley groove degree of registration instruments of inspection according to the present invention is used.
Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of embodiment.
Referring to Fig. 1, this engine polywedge bet train pulley groove degree of registration instruments of inspection comprises: laser torch 1, bearing 2 and laser torch 1 is fixed to fixed card 3 on the bearing 2.Wherein, laser torch 1 is column, belong to semiconductor laser, comprise: electric torch casing 11 and the electroluminescent lamp 12 that is positioned at the laser module (not shown) of electric torch casing 11 inside and is positioned at electric torch casing 11 right-hand members, laser module wherein directly contacts with electric torch casing 11, thermal diffusivity is better, and laser beam is sent by electroluminescent lamp 12, powerful clear, range is far away.Bearing 2 is saddle-shape, the bottom have 21, two convex tendons 21 of convex tendon that two parallel interval arrange apart from the right and lefts of bearing 2 bottoms along equidistant, the spacing of two convex tendons 21 is three wheel slot pitches of benchmark belt pulley 4; The right-hand member of bearing 2 has breach 22, and this breach 22 is positioned at the centre of two convex tendons 21.Fixed card 3 is arc, the middle part draw-in groove interference fit of electric torch casing 11 and fixed card 3 arcs, and the two ends of fixed card 3 arcs are fixed to the top of saddle-shape bearing 2 by screw, laser torch 1 just has been fixed to the top of bearing 2 like this, the axis of the two is parallel, and so that electroluminescent lamp 12 and breach 22 consistencies from top to bottom.
During detection, as shown in Figure 2, first with the bearing 2 of this testing tool on three gear teeth of race of benchmark belt pulley 4, so that two convex tendons 21 block race, this moment, electroluminescent lamp 12 was positioned at the middle of two convex tendons 21, and breach 22 be positioned at these three gear teeth center tooth 41 directly over.Then, as shown in Figure 3 and Figure 4, press the switch open laser of laser torch 1, laser beam 13 is shone on the detected belt pulley 5 of same train, the hot spot 14 of observing laser beam 13 shines the position of detected belt pulley 5, in theory, this moment bearing 2 breach 22 alignment fiducials belt pulleys 4 above-mentioned three gear teeth center tooth 41 directly over, if two pulley groove degree of registration satisfy the requirement of dispatching from the factory, hot spot 14 also should impinge upon the position of the corresponding crown 51 that is verified pulley groove 5.If hot spot 14 does not impinge upon the position of the corresponding crown 51 that is verified pulley groove 5, then the degree of registration of two pulley grooves does not meet the demands.So just can judge whether two belt pulley degree of registration satisfy the engine product requirement of dispatching from the factory according to the side-play amount of hot spot 14.
Owing to having adopted laser torch to detect engine polywedge bet train pulley groove degree of registration, so that accuracy of detection is high, simple to operate.
Above disclosed only be a specific embodiment of the present invention, still, the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
