Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a hole position detection device. Background Art

[0002] Some parts have complex structures and high dimensional accuracy requirements. There are many installation holes that need to ensure position accuracy. Therefore, it is necessary to detect the position of part holes during production to reduce the defective rate. Therefore, it is necessary to use a hole position inspection device to detect the hole position of the part.

[0003] For example, the patent website discloses a device for automatically detecting the diameter of the center hole of a wheel and the position of the bolt hole (publication number: CN214843016U). This device automatically detects the diameter of the center hole and the position of the bolt hole by combining a telecentric lens and a pen-type sensor. However, it is not possible to detect online and the cost of batch detection is high. Therefore, technical personnel in this field have proposed a hole position inspection device. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a hole position inspection device, which uses a detection needle adapted to a part hole to detect whether it can be inserted into the corresponding part hole to achieve low production cost and solve the above-mentioned background problems.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a hole position measuring device, comprising:

[0006] A detection mechanism, the detection mechanism is used to detect the position of the part hole;

[0007] The detection mechanism comprises a lower template, the upper surface of the lower template is correspondingly mounted with two guide posts, the surface of each guide post is slidably provided with a guide sleeve, the sides of the two guide sleeves are jointly mounted with an upper template, a first detection needle is mounted at the center of the lower surface of the upper template, and a group of evenly distributed second detection needles are mounted on the lower surface of the upper template outside the first detection needle;

[0008] A base mechanism is arranged on the detection mechanism for placing the parts to be detected.

[0009] As a further technical solution of the utility model, two limit pins are installed on the lower surface of the upper template corresponding to the outer side of a group of second detection needles, and a spring is sleeved on each guide column between the guide sleeve and the lower template.

[0010] As a further technical solution of the utility model, the sizes of the first detection needle and all the second detection needles are adapted to the parts to be detected.

[0013] As a further technical solution of the utility model, a first magnet is embedded in the lower surface of the slide seat directly below each set of positioning pins, and a second magnet is embedded in the upper surface of the lower template directly below the first detection needle, and the second magnet has opposite magnetic poles to the first magnet.

[0014] Beneficial Effects

[0015] The utility model provides a hole position measuring device. Compared with the prior art, it has the following beneficial effects:

[0016] 1. Hole position inspection device. The inspection mechanism of this device uses the lowering of the upper template to allow the first inspection needle and the second inspection needle to be fully inserted into the hole of the part to determine whether the part hole position is qualified. It has high inspection efficiency, simple and convenient operation, can provide online inspection and batch product inspection, and has low production cost.

[0017] 2. The hole position inspection device can remove the inspected parts and replace them with uninspected parts during the parts inspection process. After the inspection of the previous part is completed, the slide is pushed to push the uninspected parts to the bottom of the first inspection needle. This method is less time-consuming than the original method of removing the inspected parts and then replacing the uninspected parts, thus speeding up work efficiency.
