DETAILED DESCRIPTION

[0024] The present invention is further described in detail below with reference to the embodiments:

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1 to 6 As shown, a workpiece detection device with precise positioning is capable of detecting an annular workpiece 100. The annular workpiece 100 is provided with multiple first positioning parts 101 and second positioning parts 102, including: a base 1, the base 1 is provided with a detection component 2 capable of detecting the inner and outer circumferences of the workpiece, the detection component 2 includes an outer ring 21 connected to the base 1 and an inner ring 22 arranged in the outer ring 21, multiple connecting parts 23 are provided between the outer ring 21 and the inner ring 22, and a receiving groove 24 is formed between two adjacent connecting parts 23, and the first positioning part 101 or the second positioning part 102 can be snapped into. The inner ring 22 is partially located in the outer ring 21, so that a first detection groove 25 capable of detecting the outer circumference of the workpiece is formed between the inner ring 22 located in the outer ring 21 and the outer ring 21, and the inner ring 22 protruding to the outer ring 21 is provided with a second detection part 26 capable of snapping with the second positioning part 102 of the annular workpiece 100.

[0027] When it is necessary to inspect the annular workpiece 100, the multiple first positioning parts 101 and the second positioning parts 102 of the annular workpiece 100 are directed towards the inner ring 22, and then the annular workpiece 100 is pushed so that the second positioning parts 102 on the inner circumference of the annular workpiece 100 can be just stuck on the inner ring 22. If the annular workpiece 100 cannot be stuck in, the size of the second positioning parts 102 set on the inner circumference of the annular workpiece 100 is problematic and it is a defective product. After passing the inspection of the inner ring 22, the annular workpiece 100 is removed, and the front side of the annular workpiece 100 is aligned with the receiving groove 24, and the annular workpiece 100 is pushed so that the annular workpiece 100 can be just stuck in the receiving groove 24. If the annular workpiece 100 cannot be stuck in, the outer circumference size of the annular workpiece 100 does not meet the processing requirements. The user can judge whether the processing of the annular workpiece 100 meets the requirements by whether the annular workpiece 100 can be stuck in the inner ring 22 or the receiving groove 24. The inspection is faster and does not require judgment by tools such as calipers, which is more efficient.

[0028] The second detection portion 26 is the outer peripheral surface of the inner ring 22. When the annular workpiece 100 is stuck on the second detection portion 26 through the second positioning portion 102, it is used to detect the injection position of the second positioning portion 102. It can detect the structure located on the inner side of the inner ring 22, which is convenient for the user to judge whether the inner side of the annular workpiece 100 meets the requirements.

[0029] The inner side of the outer ring 21 is provided with a first limiting surface 211 which can limit the outer circumference of the annular workpiece 100 and is used to detect the outer circumference of the annular workpiece 100, so that the user can judge whether the outer side of the annular workpiece 100 meets the requirements by observing whether the outer shape of the outer ring 21 is deformed.

[0030] The inner ring 22 is provided with a support surface 221 capable of supporting the annular workpiece 100 so that the annular workpiece 100 is located in the first detection groove 25. The support surface 221 is used to support the annular workpiece 100 and also to limit the distance at which the annular workpiece 100 is inserted.

[0031] The inner ring 22 is further provided with a plurality of support arms 222 , which support the inner ring 22 and prevent the inner ring 22 from deforming.

[0032] The multiple support arms 222 are arranged in an X shape, so that the inner ring 22 has sufficient supporting force and a better supporting effect.

[0033] The base 1 and the detection component 2 are an integrally formed structure and can be integrally injection molded by a mold, which is convenient for processing and production.

[0034] The inner ring 22 and the outer ring 21 are both circular rings, which are convenient for matching with the annular workpiece 100 .

[0035] The base 1 and the detection assembly 2 are made of plastic and have sufficient hardness to allow the annular workpiece 100 to be inserted therein.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
