Detailed Description
An embodiment of a simple tool for measuring the inner diameter of a differential case according to the present invention will be further described with reference to fig. 1 and 2.
The utility model provides a simple and easy instrument for differential mechanism casing internal diameter measurement, includes outer barrel 1, the spiro union has screw rod 2 in the outer barrel 1, set up two vertical logical grooves 4 on the outer wall of outer barrel 1, the one end that leads to groove 4 is rotated and is connected with and rotates post 8, it can hold measuring stick 3 in leading to groove 4 to rotate fixedly connected with on the post 8, the one end of screw rod 2 is rotated and is connected with trace 13, the one end of trace 13 is fixed with two stay cords 12, the tip at measuring stick 3 is fixed to the one end of stay cord 12.
When the inner diameter of the differential shell is measured, firstly, the differential shell is positioned and fixed by a clamp of the differential shell, an outer cylinder 1 is vertically extended into the differential shell and then fixed by the clamp, then, a screw rod 2 is rotated, the screw rod 2 drives a linkage rod 13 which is rotationally connected with the screw rod to move in the vertical direction, so that a pull rope 12 moves upwards, a measuring rod 3 is driven to rotate around a rotating column 8 in the upward movement process of the pull rope 12, the measuring rod gradually extends out of a through groove 4 and gradually approaches to the inner wall of the differential shell until the screw rod is collided with the inner wall of the differential shell, the screw rod 2 can not be rotated again at the moment, the movement amount of the screw rod 2 in the vertical direction is calculated by multiplying the number of turns of the rotation of the screw rod 2 by a screw pitch, the movement amount of the screw rod 2 in the vertical direction can obtain the rotation angle, because the length of the detection rod is fixed, the distance from the end part of the detection rod to the outer cylinder body 1 can be obtained, and the inner diameter of the outer cylinder body 1 can be added to obtain the radius in the differential shell.
The rotation column 8 that this embodiment is preferred is gone up the cover and is equipped with the torsional spring 9, the one end and the outer barrel 1 of torsional spring 9 are fixed, and the other end is fixed with measuring stick 3, and the torsional spring 9 in this embodiment is used for keeping the state of measuring stick 3 in leading to groove 4, can utilize the automatic re-setting of measuring stick 3 when measuring to finish simultaneously.
In the preferred embodiment, the outer cylinder body 1 is provided with a flange 5, the flange is provided with a plurality of fixing screw holes, the fixing screw holes are internally screwed with fixing bolts 7, and the fixing bolt can be conveniently fixed on the support.
In the preferred embodiment, a rotating handle 6 is arranged at one end of the screw rod 2, so that the screw rod 2 can be conveniently rotated.
The preferred outer barrel 1's of this embodiment inner wall is equipped with vertical guide way 10, be equipped with the guide bar 11 that stretches into guide way 10 on the trace 13, lead to trace 13, avoid its rotation to drive stay cord 12 and rotate and influence measured data.
