Abstract
The utility model discloses a transmission device used for horizontal movement of a roundness measuring instrument sensor, which comprises a hand wheel, slide plates arranged on a left and a right mobile plankers, a sensor, a micro motor, a reducer, a worm wheel and worms fixed on the slide plates. The worm wheel and the micro motor are arranged on fixed plates on the left and the right mobile plankers; the output shaft of the micro motor is connected with the worm wheel by the reducer and meshed with the worms; the hand wheel is connected with one end of the worms. The roundness measuring instrument of the transmission device of the utility model measures the outer diameter or the roundness of holes of wheel shaft parts, and precise positioning and higher measuring efficiency can be achieved.
Description
Technical field
The utility model relates to a kind of substantially horizontal mobile gear, but particularly a kind of roundness measuring instrument sensor contact pilotage and tested part automatic high speed and low speed convergence location, but the also transmission device of manual drives running fix.
Technical background
Judge for the external diameter of high-precision dish axial workpiece or the circularity in hole, generally all rely on various types of roundness measuring instruments to measure, and the roundness measuring instrument sensor of measuring part must be vertically and the moving of horizontal left and right directions, and arrives required tested part position to realize the sensor contact pilotage.
The drive mechanism that the substantially horizontal that will realize traditional roundness measuring instrument sensor moves generally all adopts manual drives mode (referring to Fig. 1), and it comprises slide 1, handwheel 2, slide plate 3, sensor 4.During work, drive slide plate 3 and sensor 4 with handwheel 2, thereby realization sensor 4 contact pilotages arrive required tested part position, efficient is measured in raising for this and severely restricts are all brought in the accurate location of assurance.
The model utility content
For solving the technical problem that exists in the prior art, but the utility model provides a kind of and makes sensor carry out automatic high speed, low speed in the horizontal direction to move the transmission device that also manual drives moves, thereby improves the accurate Location accuracy of measuring efficient and guaranteeing sensor contact pilotage and tested part.
The utility model is achieved by the following technical programs:
A kind ofly be used for the transmission device that the roundness measuring instrument sensor moves horizontally, comprise handwheel, place slide plate, sensor on the move left and right planker, it is characterized in that; Described transmission device also comprises micromachine, retarder, worm gear, is fixed in the worm screw on the slide plate.Turbine and micromachine place deciding on the plate of described move left and right planker, and the output shaft of micromachine by retarder be connected with worm gear and and worm meshing, handwheel links to each other with worm screw one end.
Also comprise an extension spring, the one end is fixed in to be decided on the plate, and the other end is connected with the fork that the micromachine end face is connected.
Described transmission device and a roundness measuring instrument moving sliding base vertically are connected.
Owing to adopt above technological scheme, when micromachine at a high speed or when slowly running, make the worm gear rotation, thereby the slide plate that drives in worm screw and the continuous planker thereof moves as substantially horizontal by retarder.Otherwise micromachine is under halted state, because the damping function of retarder remains static worm gear.When rotating the worm screw handwheel by hand the continuous sensor of planker slide plate is moved in the horizontal direction.Owing to can make the gapless engagement of worm and gear under the described extension spring effect, the assurance sensor moves all in automatic still manual substantially horizontal can accurately be located and be improved measurement efficient.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Shown in Fig. 2-1,2-2,2-3,3-1,3-2, the utility model comprises handwheel 8, place slide plate 7, sensor 9, micromachine 4, retarder 5, worm gear 6 on the move left and right planker, be fixed in the worm screw 1 on the slide plate, extension spring 2.Worm gear 6 places deciding on the plate of move left and right planker with micromachine 4, and the output terminal of micromachine 4 is connected with worm gear 6 by retarder 5 and meshes with worm screw 1.Handwheel 8 links to each other with worm screw 1, and an end of extension spring 2 is fixed in to be decided on the plate, and the other end is connected with the fork 3 that micromachine 4 end faces are connected, and under the effect of extension spring 2, makes worm gear 6 and worm screw 1 can eliminate the back lash automatically by fork 3.
When tested part 10 does not also contact with sensor 9, start automatic button, micromachine 4 makes worm gear 6 rotations that are connected on its output shaft by retarder 5.Because worm screw 1 is fixedly connected on the slide plate 7 of move left and right planker, thereby realize worm gear 6 can be at a high speed or low speed drive worm screw 1 and slide plate 7 and sensor 9 and move accurate automatically location the when the contact pilotage of sensor 9 contact with tested part 10 in the horizontal direction with tested part 10 convergences.Otherwise at manual state, motor 4 stops, and worm gear 6 is static, rotate handwheel 8 by hand and drive worm screw 1 rotation, because of retarder 5 damping functions, worm screw 1 drive slide plate 7 and sensor 9 also can be moved as substantially horizontal, accurately locate with contacting of tested part 10 until contact pilotage to sensor 9.
More than show and described basic principle of the present utility model and major character and advantage thereof.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
