[0019] The present invention provides a digital caliper inspection and calibration device, which has the following beneficial effects:

[0020] 1. The inspection and calibration equipment of the digital caliper is used to inspect the accuracy of the outer card and the inner card of the digital caliper by setting the first inspection mechanism and the second inspection mechanism. After fixing the position of the digital caliper, the user needs to hold the block gauge or the ring gauge to inspect and calibrate the accuracy of the outer card or the inner card of the digital caliper. The contact position and inclination of the block gauge or the ring gauge with the outer card or the inner card can easily affect the inspection result. Therefore, the first inspection mechanism and the second inspection mechanism are set to fix the position of the block gauge and the ring gauge, so as to facilitate smooth contact and inspect the measurement accuracy of the inner card or the outer card.

[0021] 2. The inspection and calibration equipment of the digital caliper is provided with a first inspection mechanism and a second inspection mechanism. After inspecting the accuracy of the inner card and the outer card, the angles of the first connecting rod and the second connecting rod can be adjusted respectively, so that the block gauge and the ring gauge are located above the bent pipe, and the bent pipe is used to supply air to the block gauge and the ring gauge, so as to promote dust to be separated from the block gauge or the ring gauge and reduce the impact on the inspection work.

[0022] 3. The inspection and calibration equipment of the digital caliper can fix and move the digital caliper by setting a placement mechanism. Before fixing the digital caliper, the digital caliper can be manually placed in the circular groove to inspect the depth measurement of the digital caliper. After fixing the digital caliper, the light tube can be turned on to inspect the light transmittance of the inner and outer cards of the digital caliper. If the outer or inner card is light-transmissive, it will affect the measurement data of the digital caliper, resulting in inaccurate inspection results.

[0023] 4. The inspection and calibration equipment of the digital caliper can limit the position of the fixed component by setting a limit component, thereby assisting the inspection work of the first inspection mechanism and the second inspection mechanism. After the digital caliper is fixed, the fixed component can be vibrated to promote the dust on the outside of the digital caliper to fall off. When performing a light transmission inspection on the digital caliper, the light can be blocked by controlling the position of the baffle to make the light appear indirectly, which is convenient for observing whether the light can pass through the outer card or the inner card.
