Description

Technical Field

Patent publication number CN210923057U discloses a valve body height detection device, whose structure includes a mounting base plate, a transfer device, a product tooling, and a measuring device; wherein the transfer device is fixed to the upper surface of the mounting base plate, the product tooling is arranged on the upper surface of the transfer device, and the measuring device is arranged directly above the product tooling, and the bottom is fixedly connected to the side of the mounting base plate. Advantages of the utility model: the device has a simple structure, a reasonable structure, and low investment cost; the entire detection process does not require human participation, and is suitable for batch online detection with the assembly line, and the operation is simple and fast, reducing the repetitive labor intensity of the operation; eliminating human influence factors, the detection device adopts a high-precision displacement sensor, which effectively improves product quality and detection accuracy; the detection process realizes automatic detection and judgment, with a high degree of automation, and the operator only needs to simply load and unload materials, which can greatly improve production efficiency.

[0003] In the existing technology, the above-mentioned device still has certain limitations during actual use. Although it can automatically measure the height of the valve body to ensure high-precision measurement, it can only perform clamping measurement of a single valve body at a time. Therefore, it is necessary to reset and re-clamp a new valve body each time and then move a certain distance to re-measure, resulting in the reciprocating stroke being restricted to a valve body. If multiple valve bodies need to be measured, the back and forth movement takes a long time, reducing the applicability of the device in multi-valve body measurement. Utility Model Content

[0032] It should be noted that the measuring device 4, product tooling 7 and transfer device 2 in the present invention are all existing technologies in the comparative documents. The present invention has not made any modifications to them, so their functions are consistent with them. In addition, the installation position of the photoelectric sensor 502 is also consistent with the initial position of the relevant movement of the measuring device 4. The position change of the measuring device 4 during movement is used to transmit the signal through the photoelectric sensor 502. The selection of the position is also the application of conventional technical means and is common knowledge, so it will not be elaborated on.

[0033] Specifically, the photoelectric sensor 502 determines the occurrence of a transmission signal by sensing a change in the moving position of the measuring device 4 in front of it, and controls the servo motor 504 to rotate a set angle so that the second valve body enters the measuring position for measurement.
