Description
Technical field
The utility model relates to a kind of bent axle pick-up unit, specially refers to a kind of crankshaft oil seal position spiral lamination pick-up unit.
Background technology
Bent axle is important parts on the engine, and its material is made by structural carbon steel or spheroidal-graphite cast iron, has oil duct and each bearing shell to communicate in the middle of the bent axle, and engine running provides forced feed to be lubricated, to lower the temperature by lubricating oil pump later on.Engine working process is exactly that the piston process is mixed firing of compressed gas, promotes piston and does rectilinear motion, and by connecting rod power is passed to bent axle, rectilinear motion is changed into rotatablely moving by bent axle.In engine working process, the continuous oil return of oil sealing position spiral lamination on the bent axle, thus play the oil sealing effect.So-called crankshaft oil seal position spiral lamination refers to be arranged on the fine and closely woven spiral lines of toggle-action lever portion seal section outer round surface, because the rotation direction of crankshaft oil seal position spiral lamination is pointed to crankcase inside, the lubricating oil that is attached to toggle-action lever portion surface when bent axle rotates along crankshaft oil seal position spiral lamination to the crankcase internal flow, thereby play the oil sealing effect.The detection of the crankshaft oil seal position spiral lamination of prior art is normally estimated, and range estimation is because artificial factor etc. are difficult to clearly judge the spiral lamination rotation direction, in the crankshaft operation process, if crankshaft oil seal position spiral lamination rotation direction is not right, lubricating oil can throw away bent axle and produce leakage of oil, and can make crankcase temperature raise, and then influence the life-span of engine.Obviously, prior art crankshaft oil seal position spiral lamination detection method does not exist can accurately judge rotation direction, influences problems such as normal working of engine.
The utility model content
Can accurately not judge rotation direction for what solution prior art crankshaft oil seal position spiral lamination detection method existed, influence problems such as normal working of engine.The utility model proposes a kind of crankshaft oil seal position spiral lamination pick-up unit.
A kind of crankshaft oil seal position spiral lamination pick-up unit, it is characterized in that: this device comprises base plate, gear train, fixed mechanism and testing agency, described gear train is arranged on base plate one end, comprise frame, motor and shaft coupling, motor is fixed on the frame, motor transmission shaft is connected with shaft coupling one end, and the shaft coupling other end is provided with the pilot hole that is complementary with crank rod to be detected end; Fixed mechanism is arranged on the base plate other end, comprise base, support, pressing plate, briquetting, V-block and latch segment, base is fixed on the base plate, the base both sides are provided with support, and support top is provided with groove, are inlaid with V-block in the groove, pressing plate is arranged on a top of the trellis, pressing plate and junction, support two ends are provided with latch segment, and the pressing plate middle part is provided with groove, and is provided with briquetting in groove; Testing agency comprises counterweight and flexible clue, and counterweight is suspended on the oil sealing position spiral lamination section of crank rod to be detected portion by flexible clue.
Further, described rack groove bottom and contact position, pressing plate bottom are provided with setting nut.
The useful technique effect of the utility model crankshaft oil seal position spiral lamination pick-up unit is the rotation direction of accurate detection crank rod portion oil sealing position spiral lamination, has guaranteed sealing effectiveness, has guaranteed the normal operation of engine.
Description of drawings
Accompanying drawing 2 is the A place enlarged drawing of accompanying drawing 1.
Below in conjunction with the drawings and specific embodiments the utility model crankshaft oil seal position spiral lamination pick-up unit is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model crankshaft oil seal position spiral lamination pick-up unit, and accompanying drawing 2 is the A place enlarged drawing of accompanying drawing 1, among the figure, 1 is motor, and 2 is shaft coupling, and 3 is pressing plate, 4 is support, and 5 is briquetting, and 6 is V-block, 7 is counterweight, 8 is bent axle, and 9 is base plate, and 10 is base, 11 is latch segment, 12 setting nuts.As seen from the figure, a kind of crankshaft oil seal position spiral lamination pick-up unit, this device comprises base plate 9, gear train, fixed mechanism and testing agency, gear train is arranged on base plate 9 one ends, comprise frame, motor 1 and shaft coupling 2, motor 1 is fixed on the frame, and motor transmission shaft is connected with shaft coupling 2 one ends, and shaft coupling 2 other ends are provided with the pilot hole that is complementary with bent axle 8 boom ends to be detected; Fixed mechanism is arranged on base plate 9 other ends, comprise base 10, support 4, pressing plate 3, briquetting 5, V-block 6 and latch segment 11, base 10 is fixed on the base plate 9, base 10 both sides are provided with support 4, and support 4 tops are provided with groove, are inlaid with V-block 6 in the groove, pressing plate 3 is arranged on support 4 tops, pressing plate 3 is provided with latch segment 11 with junction, support 4 two ends, and pressing plate 3 middle parts are provided with groove, and are provided with briquetting 5 in groove; Testing agency comprises counterweight 7 and flexible clue, and counterweight 7 is suspended on crank rod to be detected portion 8 oil sealing position spiral lamination sections by flexible clue.Support 4 bottom portion of groove and contact position, pressing plate 3 bottom are provided with setting nut 12.The utility model crankshaft oil seal position spiral lamination pick-up unit is in the actual detected process, at first bent axle 8 is fixed on the support 4, support 4 bottom portion of groove and contact position, pressing plate 3 bottom are provided with setting nut 12 and are used for regulating the height of bent axle 8 on support 4, make bent axle 8 bar portions and motor 1 transmission shaft on same axis, bent axle 8 boom ends insert in shaft coupling 2 pilot holes.Then pressing plate 3 is pressed in support 4 tops, carry out fastening at pressing plate 3 and the latch segment 11 that junction, support 4 two ends arranges, and push down bent axle to be detected 8 bar portions with briquetting 5, motor 2 rotates the accurate detection of the vibration influence crankshaft oil seal position spiral lamination that produces when preventing from detecting, and the flexible clue of counterweight 7 usefulness is suspended on the oil sealing position spiral lamination section of crank rod to be detected portion 8.Open motor 1 switch, the transmission shaft of motor 1 drives shaft coupling 2 and rotates, and shaft coupling 2 is connected with bent axle 8 boom ends, and drives bent axle 8 rotations, begins crankshaft oil seal position spiral lamination is detected.Rotation direction according to designing requirement crankshaft oil seal position spiral lamination should be pointed to crankcase inside, and when being about to counterweight and being placed on the oil sealing position spiral lamination section of left and right bar portion of bent axle, counterweight all should move to holder orientation.Otherwise the rotation direction of crankshaft oil seal position spiral lamination is defective.
