Detailed description of the invention
In order better to understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is entered to oneThe description of step.
The utility model comprises air flue test platform 1, cylinder sleeve centre bore 2, located lateral piece 3, lead-screw drive mechanism 4, horizontal strokeTo Position Scale 5, horizontal retaining mechanism 6, laterally steering groove 7, block 8, clamp mechanism 9, pinion 10, drive motors 11, snailWorm and gear mechanism 12, gear wheel 13, longitudinal register piece 14, tooth bar 15, longitudinally guiding groove 16, longitudinal register scale 17, longitudinal lockTight mechanism 18, bidirectional ratchet 19, longitudinal vernier scale 20, horizontal vernier scale 21.
As shown in Figure 1, air flue test platform 1 is the wear-resisting steel plate of 400 × 1500 × 50mm, offers laterally on itGathering sill 7 and longitudinally guiding groove 16. Laterally steering groove 7 and longitudinally guiding groove 16 are respectively located lateral piece 3 and longitudinal register piece14 movement provides guide effect. Cylinder sleeve centre bore 2 is a manhole, the installing hole of cylinder sleeve during for air flue test. Wherein, instituteState located lateral piece 3 and longitudinal register piece 14 can be processed into monoblock type or split type.
As shown in Figure 2, the locating surface of located lateral piece 3 is the wear-resisting steel plate of 200 × 80 × 10mm, near laterally fixedThe right and left of piece 3 bottoms, position be provided with laterally steering piece, described laterally steering piece and laterally steering groove 7 coordinate as T-shaped groove etc.Carry out the guiding of transverse shifting, and then realize the located lateral of cylinder cap.
Lead-screw drive mechanism 4 drives located lateral piece 3 front and back in laterally steering groove 7 to slide for one handle drives leading screw,Its position is by the located lateral scale 5 of inlaying along laterally steering groove 7 and the horizontal vernier scale 21 that is embedded in located lateral piece 3 sidesRead. The center-aligned of the zero-bit of located lateral scale 5 and cylinder sleeve centre bore 2, the precision of located lateral scale 5 is 0.1mm, horizontal strokeBe the distance of cylinder axis to cylinder cap located lateral side to the reading of Position Scale 5.
Laterally retaining mechanism 6 is an eccentric locking mechanism, is arranged in located lateral piece 3 two ends, base plate left and right. When laterally fixedPosition piece 3 depresses by the handle of horizontal retaining mechanism 6 locking realizing located lateral piece 3 after having located, and prevents process of the testIn be moved.
Clamp mechanism 9 is arranged on located lateral piece 3 and block 8, is made up of cylinder cap location a threaded rod, pressing plate, nutFirst be close to cylinder cap side with block 8 afterwards, then clamp by nut with pressing plate, prevent that in process of the test, cylinder cap is moved.
As shown in Figure 3, the locating surface of longitudinal register piece 14 is the wear-resisting steel plate of 200 × 80 × 10mm, near longitudinalThe right and left of locating piece 14 bottoms is provided with longitudinally guiding piece, and described longitudinally guiding piece and longitudinally guiding groove 16 as T-shaped groove etc. are joinedClose the guiding vertically moving, realize the longitudinal register of cylinder cap.
Drive motors 11 driving pinions 10 and gear wheel 13, gear wheel 13 be arranged on the tooth bar in longitudinally guiding groove 1615 engagements, drive longitudinally gathering sill 16 fast moving of longitudinal register piece 14.
Worm-and-wheel gear 12 is by bidirectional ratchet 19 driving pinions 10 and gear wheel 13. In the time that drive motors 11 drivesConversion bidirectional ratchet 19 power transmission directions make worm-and-wheel gear 12 inoperative. Drive motors 11 drives longitudinal register piece 14 preliminaryBehind location, swinging handle drives worm-and-wheel gear 12 accurately to locate longitudinal register piece 14, and its position is by longitudinally leadingThe longitudinal register scale 17 of inlaying to groove 16 is read with the longitudinal vernier scale 20 that is embedded in longitudinal register piece 14 sides. Longitudinal registerThe center-aligned of the zero-bit of scale 17 and cylinder sleeve centre bore 2, the precision of longitudinal register scale 17 is 0.1mm, longitudinal register scale17 reading is the distance of cylinder axis to cylinder cap longitudinal register side.
Longitudinally retaining mechanism 18 is an eccentric locking mechanism, is arranged in longitudinal register piece 14 two ends, base plate left and right, when longitudinallyLocating piece 14 depresses by the handle of longitudinal retaining mechanism 18 locking realizing longitudinal register piece 14 after having located, and prevents testIn process, be moved.
The utility model course of work is: when air passage of internal combustion engine test, first determine cylinder axis according to the size of cylinder capTo the distance of cylinder cap the first horizontal and vertical side of cylinder. Make lead-screw drive mechanism 4 drive located lateral piece 3 edges by turning handleLaterally steering groove 7 moves, until laterally vernier scale 21 at the reading of located lateral scale 5 and cylinder axis to cylinder cap transverse sideDistance is consistent, then horizontal retaining mechanism 6 is locked, and now makes bidirectional ratchet 19 reversely dally. Then by driving electricityMachine 11 drives longitudinally gathering sill 16 fast moving of longitudinal register piece 14, until longitudinally vernier scale 20 at longitudinal register scale 17Reading and cylinder axis to the longitudinal lateral distance of cylinder cap approaches, then changes the direction of bidirectional ratchet 19, makes snail by turning handleWorm and gear mechanism 12 drives at a slow speed longitudinal register piece 14 accurately to locate it, finally longitudinal retaining mechanism 18 is locked. ThisTime the cylinder cap of test use pushed to air flue test platform 1, make the horizontal and vertical side of cylinder cap one cylinder abut against respectively lockingOn the locating surface of located lateral piece 3 and longitudinal register piece 14, be close to cylinder cap another side with block 8, by clamp mechanism 9 from cylinderCover along cylinder cap is clamped. Complete and unclamp clamp mechanism 9 and longitudinal retaining mechanism 18 after the test of the first cylinder air flue, will longitudinally determinePosition piece 14 moves the OC distance of two cylinders, then repeats the locking of longitudinal retaining mechanism 18 and clamp mechanism 9 to cylinder capClamp, continue the test of the second cylinder air flue, complete by that analogy the test to all air flues.
Above embodiment of the present utility model is had been described in detail, but described content is only of the present utility model betterEmbodiment, can not be considered to for limiting practical range of the present utility model. All equalizations of doing according to the utility model scope becomeChange and improvement etc., within all should still belonging to this patent covering scope.
