A kind of cubing of fast detecting input shaft arc groove axial location
Technical field:
The utility model relates to a kind of cubing of fast detecting input shaft arc groove axial location, belongs to the appliance special for detecting technical field.
Background technology:
Input shaft one end of automobile steering device is manufactured with an arc groove, in order to detect the precision of arc groove at axial location, general common metering system is: select the suitable pole of R of a diameter and arc groove, the gauger stands in part on the flat board earlier, with finger pole is fixed in the arc groove again; The another hand is handled height gauge on flat board, measure the pole peak to dull and stereotyped height value, then by converting, differentiates input shaft arc groove axial location size A whether qualified (referring to accompanying drawing 1).The drawback of this detection mode is: measure not only time-consumingly, and measured value is inaccurate.
Summary of the invention:
The purpose of this utility model is, provides whether a kind of to differentiate the arc groove axial location fast and accurately qualified, and detection mode is directly perceived, convenient and swift.And simple in structure, make the cubing that is easy to fast detecting input shaft arc groove axial location.
The utility model is to realize above-mentioned purpose by the following technical solutions:
The cubing of this fast detecting input shaft arc groove axial location is made of cubing body, register pin, cover plate, compression spring and detection slide plate, it is characterized in that: the middle part of cubing body has a locating slot, compression spring and register pin are housed in the locating slot, by sunk screw cover plate are housed on the cubing body above the locating slot; One end of cubing body by screw be equipped with logical, end two and detect slide plates.
The utility model beneficial effect compared with prior art is:
The cubing of this fast detecting input shaft arc groove axial location adopts input shaft is put on the cubing body, the arc groove of input shaft is enclosed within on the register pin, can guarantee the accuracy of the input shaft part axial location on the cubing, again by two logical, only detect slide plate, can fast detecting whether go out the arc groove axial location qualified.Time-consuming taking a lot of work when having solved existing input shaft arc groove axial location detection mode and measuring, and the inaccurate problem of measured value.

Fig. 4 is the B-B cut-open view of Fig. 2.
Among the figure: 1, sunk screw, 2, cover plate, 3, compression spring, 4, register pin, 5, the cubing body, 6, detect slide plate, 7, screw, 8, locating slot, 9, flat board, 10, height gauge, 11, input shaft.
Embodiment:
The cubing of this fast detecting input shaft arc groove axial location is made of cubing body 5, register pin 4, cover plate 2, compression spring 3 and detection slide plate 6, the middle part of cubing body 5 has a locating slot 8, compression spring 3 and register pin 4 are housed in the locating slot 8, by sunk screw 1 cover plate 2 is housed on the cubing body 5 above the locating slot 8, is manufactured with the fixing shrinkage pool of compression spring 3 on the cover plate 2.The both sides of cubing body 5 one ends have groove, respectively are equipped with one by screw 7 in the groove and lead to, only detect slide plate 6 (referring to accompanying drawing 2-4).
When the cubing of this fast detecting input shaft arc groove axial location is used, input shaft 11 is put on the cubing body 5, arc groove is enclosed within on the register pin 4, pin the plane that cylindrical that input shaft 11 makes the circular arc trough rim is close to cubing body 5 with the thumb of proficiency; Whether rotate with the another hand and lead to, end two detection slide plates 6, it is qualified to detect the arc groove axial location; Logical detection slide plate 6 can pass through, and the detection slide plate 6 that ends can not pass through then for qualified.Eliminated the foozle of tested part cylindrical and arc groove itself, both guaranteed the accuracy of input shaft axial location on the cubing, again can fast detecting whether go out the arc groove axial location qualified.
