Problems solved by technology
Because there is a gap between the actually processed fork shaft arc and the measuring rod, it is impossible to ensure that it is completely level when placed in the arc groove, and the height difference can only be measured after repeated fine-tuning to ensure that the measuring rod is perpendicular to the fork shaft , each workpiece measurement process takes an average of 2 minutes, and the actual deviation value of the workpiece cannot be intuitively obtained

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] see Figure 1 to Figure 7 , an auxiliary measuring device for the axial dimension of the shift fork shaft, including a base 4 for fixing the standard part 1, and a wedge pin 2 for inserting into the arc groove of the standard part 1, and a through hole is opened on the wedge pin 2 , the cylindrical pin 3 is fixed in the through hole, and is equipped with a digital display height gauge. The wedge pin 2 includes a semicircular base. The end of the wedge pin 2 with a large thickness.
[0029] There is a semicircular groove with the same circular arc as the shift fork shaft on the standard part 1. The axial dimension of the semicircular groove is the axial dimension standard difference of the shift fork shaft. An auxiliary measuring device for the axial dimension of the shift fork shaft The method of use includes the following steps:
[0030] Step 1, fixing the c...

The invention discloses a fork shaft axial size auxiliary measuring device and a use method. The fork shaft axial size auxiliary measuring device includes a base for fixing a standard component and a wedge pin which can be plugged into a circular arc groove of the standard component; a through hole is formed in the wedge pin; a cylindrical pin is fixed in the through hole; a digital display height gauge is adopted; the difference value of a component to be measured and the standard component is calculated; and a value on the digital display height gauge is compensated, so that a standard value can be obtained, and then, measurement is carried out to obtain the axial size of the component to be measured. After the fork shaft axial size auxiliary measuring device is applied to field use, the measurement time of a first workpiece can be shortened to 1 minute or less, and the average measurement time of workpieces from a second workpiece is about 20 seconds, and measurement steps can be simplified, and a desired goal can be achieved.
Description
technical field [0001] The invention belongs to the field of shift fork shaft measurement, and in particular relates to an auxiliary measuring device for the axial dimension of a shift fork shaft and a use method. Background technique [0002] For existing shift fork shaft parts, it is necessary to ensure the distance between the center of the arc groove and the end face. For this distance, the usual measurement method is to use a cylindrical measuring rod, a V-shaped block and a digital display height gauge to measure the arc groove on the shift fork shaft. Bottom-to-end distance. Because there is a gap between the actually processed fork shaft arc and the measuring rod, it is impossible to ensure that it is completely level when placed in the arc groove, and the height difference can only be measured after repeated fine-tuning to ensure that the measuring rod is perpendicular to the fork shaft , each workpiece measurement process takes an average of 2 minutes, and the act...
