Description
Technical Field
The utility model belongs to the technical field of machining, in particular to quick detection device of installation locating pin length dimension.
Background
As shown in fig. 1, when the positioning pin is installed on the connection ring, the requirement on the dimensional accuracy of the length of the installation positioning pin extending out of the end face of the connection ring is high. In the actual production process, the detection mode after the positioning pin is installed is that a depth caliper is generally used for detection. Because to certain type composite head cover go-between installation locating pin process, because area of contact is less when the degree of depth slide caliper is measured, to the field survey operation degree of difficulty increase. And when batch production assembly detects, it is lower to adopt traditional depth caliper rule detection mode efficiency.
For the short-term test that improves behind the compound hood go-between installation locating pin to the locating pin stretch out go-between terminal surface size, need a short-term test device now, can realize the short-term test of length behind the assembly locating pin, in actual production process, easy operation, production efficiency is high.
SUMMERY OF THE UTILITY MODEL
To the problem that exists, provide a go-between locating pin length short-term test device, can realize detecting the length dimension that the locating pin stretches out the go-between terminal surface after go-between and locating pin assembly, need not to use the depth slide caliper rule to detect, only need use this device, just can judge fast whether the length dimension that the locating pin stretches out the go-between terminal surface accords with the tolerance requirement
The utility model provides a quick detection device of installation locating pin length dimension, includes: a depth detection device T and a depth detection device Z;
the depth detection device T and the depth detection device Z are both plate-shaped, and a blind hole is formed in the edge of one side of the depth detection device T and the depth detection device Z;
the depth of the blind hole in the depth detection device T is equal to the minimum value of the size of the positioning pin extending out of the end face of the connecting ring, and the depth of the blind hole in the depth detection device Z is equal to the maximum value of the size of the positioning pin extending out of the end face of the connecting ring.
Further, the diameter of the blind hole is in clearance fit with the diameter of the positioning pin.
Further, the depth detection device T and the depth detection device Z are both in an L-shaped plate shape, and a blind hole is formed in the inner end face of one edge.
Furthermore, the depth direction of the blind hole is parallel to the other edge of the L-shaped plate.
Further, the depth detection device T and the depth detection device Z are made of metal.
Further, the thickness of the depth detection device T and the depth detection device Z is not less than 5mm.
Has the advantages that: the application provides a go-between locating pin length short-term test device can realize when go-between installation locating pin, need not to use depth caliper rule to detect, only needs to use this device, just can judge whether the length dimension that the locating pin stretches out the go-between terminal surface meets the requirements. In the actual production process, the operation is simple, and the production efficiency is high.

Detailed Description
Referring to fig. 2 and 3, a device for rapidly detecting the length and the size of a positioning pin of a connecting ring is composed of a depth detection device T with the serial number 3 and a depth detection device Z with the serial number 4. The serial number 3 depth detection device T and the serial number 4 depth detection device Z are designed to have stronger universality, and the serial number 3 depth detection device T and the serial number 4 depth detection device Z are required to be combined for use in the use process, which is basically defined as that the serial number 3 depth detection device T is designed to be the minimum value of the dimension of the positioning pin extending out of the end face of the connecting ring, and the serial number 4 depth detection device Z is designed to be the maximum value of the dimension of the positioning pin extending out of the end face of the connecting ring. Wherein the size of the gap sizes delta 1 and delta 2 is determined by the length of the positioning pin required to extend out of the connecting ring after the positioning pin is installed on the connecting ring. The qualification criterion in the process of using the depth detection device T with the sequence number 3 and the depth detection device Z with the sequence number 4 in a combined way is as follows: when the depth detection device T with the serial number 3 is used and is completely contacted with the upper end surface of the connecting ring positioning pin, the delta 1 dimension is exposed; and the depth detection device Z with the use serial number 4 is replaced, and delta 2 exposure is met after the depth detection device Z is contacted with the end face of the connecting ring. The installation positioning pin for installing the connecting ring is met, and the length dimension of the positioning pin extending out of the connecting ring meets the tolerance requirement when the requirements are met.
The device for rapidly detecting the length of the connecting ring positioning pin can be used for judging whether the length of the positioning pin extending out of the end face of the connecting ring meets the requirement or not by only using the device without using a depth caliper for detection when the positioning pin is installed on the connecting ring. In the actual production process, the operation is simple, and the production efficiency is high.
