Embodiment 1

[0025] Embodiment 1, the present invention includes a moving box, a sliding assembly, a rotating assembly, and a shooting assembly; Fitted with the guide rail to be tested; the sliding assembly includes a handle 5, a sliding body 6, a lead screw 7, and a mobile platform 8, and the sliding body 6 is fixed above the outer box 2, and the upper surface of the body is provided with a sliding track, the mobile platform 8 is installed above the sliding track, and the lower end is provided with a threaded hole, and one end of the screw 7 is provided with a handle 5, which passes through the threaded hole at the lower end of the mobile platform 8 and is installed on the sliding body 6; the rotating assembly It includes a rotating base 9, a worm 21, a rotating platform 10, and a fixed block 11. The rotating base 9 is fixed on the top of the mobile platform 8. The overall shape is semicircular and the diameter at both ends is large and the diameter in the middle is small. There are circum...

Embodiment 2

[0026] Embodiment 2, the working process of the present invention: connect the light 27 and the eyepiece 17 to the external power supply and the computer, adjust the eyepiece moving device 14 and the square block 19 to an appropriate position and tighten them, and place the light device 20 along the inside of the square block 19. The hole is moved so that the centerline of the eyepiece 17 and the centerline of the light 27 are roughly on a straight line, the relative position of the eyepiece 17 and the light 27 is adjusted by the fine-tuning knob 28 to make the picture quality optimal, and the handle 5 is moved to move the mobile platform 8 to an appropriate position. Position, rotate the worm 21 to realize the rotation of the rotary platform 10, so that the eyepiece 17 reaches the position perpendicular to the slope of the guide rail surface, adjust the fine-tuning knob 28 again to make the shooting effect reach the best, and then shoot, and rotate the handwheel 3 to realize th...

Abstract

Provided is an image capturing device for detecting and analyzing a machine tool guiderail surface quality. The image capturing device mainly comprises a mobile box body, a sliding assembly, a rotating assembly, and a capturing assembly. The mobile box body is mainly composed of an inner guiderail sleeve 1, an outer box body 2, a hand wheel 3, and a built-in friction wheel 4. The sliding assembly is mainly composed of a handle 5, a sliding body 6, a lead screw 7, and a mobile table 8. The rotating assembly is mainly composed of a rotating pedestal 9, a worm 21, a rotating platform 10, and a fixing block 11. The capturing assembly is connected with the fixing block 11 through a V-shaped rod 12 and mainly comprises a sliding rod 19, an ocular lens moving device 14, a U-shaped support 15, a connector 16, an ocular lens 17, a mobile square block 18, and a light device 20. The image capturing device is simple in structure and low in production cost. By the replacement of the inner guiderail sleeve, the images of large machine tool guiderail surfaces with different cross sections can be fast and accurately acquired. The image capturing device provides image support for guiderail surface wearing state identification based on machine vision detection technology, provides decision basis for taking effective measures to relieve wearing or repair the guiderail, has important significance to maintenance of machine tool precision and guarantee of product quality, and can be widely used in the field of machine tool guiderail surface quality detection.

Description

technical field [0001] The invention relates to the field of quality detection of machine tool guide rails, in particular to an image capturing device for detecting and analyzing the quality of machine tool guide rails. Background technique [0002] The accuracy of the guide rail of the machine bed directly affects the size, shape and position error of the machined parts. Therefore, whether it can maintain high-precision machining status will affect the product qualification rate and the service life of the machine tool. Therefore, the accuracy of the guide rail of the machine tool Testing is critical. Since the guide rails of the bed are exposed to the air all the year round and are not protected, the dust-proof and chip-proof conditions are poor, and wear will inevitably occur after long-term use. When the wear is serious, the machining accuracy of the parts will not meet the requirements, and even cause The guide rail fails, so wear is the root cause of the decline in th...
