[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0022] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components.

[0024] Example 1:

[0025] like Figure 1 As shown in Figure 3, a hole position inspection tool includes a base plate 1, an inner sleeve 2 is provided on the base plate 1, a product 11 is sleeved in the inner sleeve 2, a plurality of plug gauges 3 are provided on the outer periphery of the inner sleeve 2, the plug gauges 3 pass through the holes of the product 11, a probe 10 and an indicator light 5 are provided on the base plate 1, the probe 10 is electrically connected to the indicator light 5, and the indicator light 5 is fixed to one side of the base plate 1 through a mounting bracket 4; pillars 8 are provided on all sides of the bottom of the base plate 1; a mounting plate 7 is fixed to the bottom of the plug gauge 3, the mounting plate 7 is fixed below the base plate 1, and the plug gauge 3 passes through the base plate 1.

[0026] The hole position inspection tool of the present invention adopts a fixed plug gauge 3, an inner sleeve 2 and a base plate 1, so that during inspection, the worker only needs to align the hole position of the product 11 with the plug gauge 3 and press the product 11 to the base plate 1, which is convenient and fast. In addition, with the probe 10 and the indicator light 5, the bottom reference surface of the product 11 is flush with the base plate 1, and the indicator light 5 is on, which means it is qualified. The inspection speed is fast and the judgment is easy.

[0027] The substrate 1 is provided with a plurality of avoidance holes 6; since there may be protrusions on the bottom reference surface of the product 11, the setting of the avoidance holes 6 can accommodate these protrusions and prevent the protrusions from causing the bottom reference surface of the product 11 to be unable to be flush with the upper surface of the substrate 1.

[0028] The plug gauge 3 is provided with a cushion block; since the heights of the various holes of the product 11 are different, the cushion block can make up for these height differences, ensuring that the holes correspond to the plug gauge 3, so that the product 11 can be pressed to the bottom.

[0029] The probe 10 is a photoelectric sensing switch; the photoelectric sensing switch is a short name of photoelectric proximity switch, which detects whether the bottom reference surface of the product 11 is in place by using the shielding or reflection of the detected object to the light beam to turn on the circuit by the synchronous loop.

[0030] The bottom of the substrate 1 is provided with a battery 9, which provides power for the photoelectric sensing switch and the indicator light 5.

[0031] The detection step is as follows: the worker corresponds the inner sleeve 2 to the through hole of the product 11, corresponds the plug gauge 3 to the hole position, then presses the product 11 towards the substrate 1 until the product 11 cannot be moved downward, and when the bottom of the product 11 is in contact with the substrate 1, the probe 10 is pasted flat, the probe 10 senses the product 11, and the indicator light 5 is lit; at this time, the hole position detection of the product 11 is qualified; if the bottom reference surface of the product 11 cannot be placed in contact with the substrate 1, the probe 10 will not sense the product 11, and the indicator light 5 is extinguished; at this time, the hole position detection of the product 11 is unqualified.

[0032] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, and any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiment are within the scope of the technical scheme of the present application.
