The utility model is realized in such a way, a hole depth checking fixture of the automobile accessory part is constructed, which comprises a ring body and a plurality of detecting mechanisms arranged on the outer cylindrical surface of the ring body, wherein each detecting mechanism comprises an inserting shaft, and the end part of the inserting shaft is fixedly arranged on the outer cylindrical surface of the ring body;

the sliding plate is sleeved at the outer end of the insertion shaft and keeps sliding connection;

the spring is sleeved at the outer end of the insertion shaft and is fixedly arranged between the outer cylindrical surface of the annular body and the sliding plate;

and a lock nut installed at a side surface of the slide plate for fixing a position of the slide plate on the insertion shaft.

Furthermore, scales are marked on the outer cylindrical surface of the insertion shaft, and the scales are sunken on the cylindrical surface of the insertion shaft.

Furthermore, one end of the insertion shaft is fixedly connected with the outer cylindrical surface of the circular ring body, and the other end of the insertion shaft is provided with a chamfer.

Further, the angle of the chamfer formed on the insertion shaft is not more than 31 degrees.

Further, the diameters of the insertion shafts of the respective detection mechanisms are different from each other.

Furthermore, chamfers are arranged on the inner side and the outer side of the ring body.

The utility model discloses have following excellent beneficial effect:

compared with the prior art, the utility model discloses a with the shaft of the hole matching diameter who detects insert, be convenient for improve the precision that detects, can improve detection efficiency simultaneously.

The utility model discloses in, insert the angle of the chamfer and the chamfer that the axle head portion was seted up through reasonable design not only can be convenient for insert the axle and insert to detect the hole and detect to can improve the precision that detects.

Through the reasonable design of the locking nut on the sliding plate, the sliding plate is convenient to lock, and the insertion shaft is convenient to take out by a worker for reading.

The different diameter of the insertion shaft of a plurality of detection mechanisms of reasonable design can be convenient for detect the hole depth of different diameters, enlarges the range of use.

Detailed Description

The present invention will be described in detail with reference to fig. 1 to 3, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an improve the hole depth that provides an auto parts here and examine utensil can implement according to following mode: a hole depth gauge for automobile parts comprises a ring body 1 and a plurality of detection mechanisms arranged on the outer cylindrical surface of the ring body 1, wherein each detection mechanism comprises an insertion shaft 2, and the end part of each detection mechanism is fixedly arranged on the outer cylindrical surface of the ring body 1;

a sliding plate 5 which is sleeved at the outer end of the insertion shaft 2 and keeps sliding connection;

the spring 3 is sleeved at the outer end of the insertion shaft 2 and is fixedly arranged between the outer cylindrical surface of the ring body 1 and the sliding plate 5;

and a lock nut 7 installed at a side surface of the sliding plate 5 for fixing a position of the sliding plate 5 on the insertion shaft 2.

In the present embodiment, the outer cylindrical surface of the insertion shaft 2 is marked with a scale 4, and the scale 4 is recessed on the cylindrical surface of the insertion shaft 2.

In this embodiment, one end of the insertion shaft 2 is fixedly connected to the outer cylindrical surface of the torus 1, and the other end is provided with a chamfer 6.

In the present embodiment, the angle at which the insertion shaft 2 is chamfered 6 does not exceed 31 °.

Because the vertex angle of the twist drill is 118 degrees, the calculation shows that the inserting shaft 2 can be completely inserted into the hole to be detected when the chamfer angle 6 is not more than 31 degrees.

In the present embodiment, the insertion shafts 2 of the respective detection mechanisms are different in diameter.

In this embodiment, chamfers are formed on the inner side and the outer side of the torus 1.
