Embodiment Construction

[0026] This embodiment is used for detecting cylindrical cemented carbide rods, especially rods with a diameter ranging from 2.0 to 20.0 mm and a length ranging from 200 to 400 mm. For the convenience of description, the "cylindrical cemented carbide rod" is simply referred to as "rod" hereinafter.

[0027] Such as figure 1 As shown, the whole system includes a fuselage 6 with a frame structure and a feeding device 1 , a transfer device 2 , a detection device, and a sorting device 4 installed on the fuselage. The detection device includes two sub-sections, the first sub-section is a bar supporting and rotating device 31 , and the second sub-section is a bar straightness scanning device 32 . The feeding device, the detection device and the sorting device are arranged on the longitudinal center plane.

[0028] Such as figure 1 As shown, the feeding device 1 includes a slideway 11 , a fixed stepped plate 12 , a lifting stepped plate 13 , a jacking device 14 , and a side plate ...

Abstract

The invention discloses a straightness detection method of a cylindrical bar and application system of the straightness detection method. In the detection method, the dimension of the bar is measuredby adopting a laser element, and straightness of the bar can be detected by adopting an industrial grade digital camera automatically in a non-contact manner while the bar is rotated. The system comprises a feeding device, a transfer device and a detection device; the detection device comprises two parts of a bar bearing and rotating device and a bar straightness scanning device that are arrangedin parallel; the feeding device is used for feeding one bar every time; the transfer device is used for transferring the bar onto the bar bearing and rotating device; the bar is rotated stably by thebar bearing and rotating device; and the bar straightness scanning device is used for scanning the bars while the bar straightness scanning device moves in the length direction of the bar. As a machine has the characteristics of being high in vision flexibility and high in efficiency, a reference basis is provided by a high-accuracy datum background plate, the straightness of the cylindrical bar is automatically detected, and non-qualified products are removed. According to the detection method, the detection efficiency is improved, and the quality of a cylindrical bar product is ensured.

Description

technical field [0001] The invention belongs to the field of detecting the straightness of cylindrical rods, in particular to a method for detecting the straightness of cylindrical rods and its application field. Background technique [0002] The production of cemented carbide has a large number of extrusion isostatic tool rod blanks. During the factory inspection process of such products, it is necessary to carry out all inspections on the length, diameter, curvature and circular runout of the products and the shape and position tolerances one by one. At present, manual inspection is generally used. [0003] There are many problems in the manual inspection method, such as high labor intensity, low efficiency and low accuracy; different inspection personnel have different inspection results, resulting in quality objections. [0004] In order to meet the increasing requirements of product inspection standards in the market, improve the accuracy and efficiency of finished pro...
