An infrared light calibration device

Abstract

The invention discloses a novel infrared light verifying device. The novel infrared light verifying device comprises a horizontally arranged base board (2) and a stand column (4) vertically connected to the base board (2), and is characterized in that an infrared light-sensitive plate (6) is arranged on the base board (2), an infrared emitter is further arranged on the stand column (4), a first power device for driving the infrared emitter to do linear motion along a horizontal first linear track and a second power device for driving the infrared emitter to do linear motion along a horizontal second linear track are arranged on the infrared emitter, and the first linear track is perpendicular to the second linear track. The novel infrared light verifying device overcomes the defects in the background technology, is simple in method, easy to operate, low in cost, high in practicability, high in precision, and capable of measuring the location degree of multiple holes in multiple workpieces in batches.

Description

technical field [0001] The invention relates to an infrared light calibration device. Background technique [0002] With the development of modern machining and manufacturing industries, the structure of mechanical products is becoming more and more complex, and the quality requirements of the holes on the products are also increased accordingly. The position of the holes directly affects the quality of the products. With the development of the industrial system, the requirements for position accuracy and precision are getting higher and higher, and the measurement methods and means are also constantly improving. At present, data points are scanned and collected on the surface of the product under test by a three-coordinate measuring instrument to obtain the three-coordinates of the product under test within the spatial range, thereby obtaining the position of the hole on the product. [0003] However, the cost of the three-coordinate measuring instrument is high and it can...

Problems solved by technology

[0003] However, the cost of the three-coordinate measuring instrument is high and it cannot be measured in batches, which makes the production cost of the enterprise higher; in order to reduce the cost, a mandrel matching measurement method is used, that is, according to the design parameters of the measured hole, the corresponding mandrel is made, and then used The instrument measures the core rod to indirectly obtain the relevant data of the hole. Although the cost of this measurement method is low, the measurement accuracy is low, and it does not have good adaptability, because the size of the hole varies, and one rod is matched with one hole. The number of mandrels is large, and the management cost is high, so the practicability is not strong
