Dimension measuring device, dimension measuring method and dimension measuring system

Abstract

The invention discloses a dimension measuring device. The dimension measuring device comprises a driving motor; a transmission mechanism which is connected with an output shaft of the driving motor and outputs linear motion; a first sensor which is arranged at the output end of the transmission mechanism and used for sequentially detecting a first boundary position and a second boundary position of a to-be-detected part of the workpiece in the moving process; a processor which is connected with the first sensor and is used for determining a first corner position of the driving motor when a signal of a first boundary position detected by the first sensor is acquired, determining a second corner position of the driving motor when a signal that the first sensor detects the second boundary position is obtained, and calculating the distance between the first boundary position and the second boundary position according to an angle difference value between the first corner position and the second corner position. The product dimension can be automatically detected, and the measurement accuracy is high. The invention further discloses a dimension measuring method applied to the dimension measuring device and a dimension measuring system comprising the dimension measuring device.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, more specifically, to a dimension measuring device. In addition, the present invention also relates to a dimension measuring method applied to the above dimension measuring device and a dimension measuring system comprising the above dimension measuring device. Background technique [0002] In the process of automatic assembly line production, in order to ensure that the size of a certain part of the product is qualified, it is often necessary to perform size inspection on a specific part of the product to eliminate products with unqualified size. [0003] In the prior art, the operator usually holds the go-no-go gauge for detection. However, the go-no-go gauge can only judge whether the size is qualified, but cannot measure the specific value of the size, and it is not convenient to confirm the size error of a single product; on the other hand, After working for a long time, worke...

[0003] In the prior art, the operator usually holds the go-no-go gauge for detection. However, the go-no-go gauge can only judge whether the size is qualified, and cannot measure the specific value of the size, which is inconvenient to confirm the size error of a single product; on the other hand, After working for a long time, workers are prone to mental fatigue, lack of concentration, and prone to misjudgment
