Embodiment
The structural representation of an embodiment of the present invention shown in Fig. 1 to 4, Motor Shaft device for detecting length in a kind of worm and gear casing, has the location-plate 1 that contacts with the top end face 811 of worm screw mounting hole 81, threaded hole 813 corresponding register pins 11 on the top end face that is provided with on the bottom surface of location-plate 1 with the worm screw mounting hole, be provided with axle sleeve 3 on location-plate 1, axle sleeve 3 cooperates the location with spot facing 811 in the worm screw mounting hole; Be coated with the central shaft 2 that moves up and down in axle sleeve 3, central shaft 2 is provided with step I24, and endoporus 30 lower ends of axle sleeve 3 are provided with the step II31 of convex, is provided with the spring 4 of normal condition on the central shaft 2 between step I24 and the step II31; The axis of central shaft 2 overlaps with the center line 810 of worm screw mounting hole, the bottom face of central shaft 2 is provided with the distance detection head between the center line 810 of the end face 910 that detects Motor Shaft and worm screw mounting hole, detection head comprises the benchmark cylinder I21 that is located on central shaft 2 bottom faces and is located at the round platform rank 22 on benchmark cylinder I21 top, benchmark cylinder I21 and benchmark cylinder II22 are coaxial with central shaft 2, and the difference of the diameter of the diameter of benchmark cylinder II22 and benchmark cylinder II22 bigger than the diameter of benchmark cylinder I21 and the diameter of benchmark cylinder I21 is the twice of the upper deviation of the distance between Motor Shaft end face 910 and the worm screw mounting hole center line 810; Central shaft 2 tops are provided with pressure head 23, and pressure head 23 is provided with the scale that indication central shaft 2 presses down the degree of depth.
Principle of work of the present invention is as follows: location-plate is placed on the worm screw mounting hole, after having good positioning by register pin and threaded hole location and axle sleeve and spot facing, depresses pressure head, make benchmark cylinder I move to the height at Motor Shaft place, at this moment have three kinds of situations.
If the distance between the center line of the end face of a Motor Shaft and worm screw mounting hole is a normal value, benchmark cylinder I can freely move up and down at the height at Motor Shaft place, do not interfere with Motor Shaft, and after firmly depressing pressure head again, benchmark cylinder II can be blocked by Motor Shaft, and this moment, central shaft can not move down;
If the distance between the center line of the end face of two Motor Shafts and worm screw mounting hole is less than normal, just the Motor Shaft extension elongation is long, like this when depressing pressure head and make benchmark cylinder I move to Motor Shaft place height, benchmark cylinder I will interfere with Motor Shaft, be that benchmark cylinder I is blocked by Motor Shaft, central shaft can not be moved down;
If the distance between the center line of the end face of three Motor Shafts and worm screw mounting hole is bigger than normal, just the Motor Shaft extension elongation is too short, like this when depressing pressure head and make benchmark cylinder I move to Motor Shaft place height, benchmark cylinder I can freely move up and down at the height at Motor Shaft place, do not interfere with Motor Shaft, after firmly depressing pressure head again, benchmark cylinder II still can not blocked by Motor Shaft, and central shaft can also continue to move down.
In the foregoing description, interference fit between axle sleeve 3 and the location-plate 1, benchmark cylinder II22 and central shaft 2 can be made one in addition, the diameter that is central shaft 2 is identical with the diameter of benchmark cylinder II22, stretch out when too short at Motor Shaft like this, central shaft 2 can directly be pressed onto the end, need not read scale and just know testing result.
Whether satisfy technical requirement by the distance between the center line of observing end face that scale analysis on the pressure head draws Motor Shaft under above-mentioned three kinds of situations and worm screw mounting hole, if do not satisfy, then judge it is bigger than normal or less than normal, simple in structure, easy to make, use simple and fast.
Except that above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
