The invention discloses a device for measuring the straightness of a guide rail and a measuring method thereof. The device for measuring the straightness of the guide rail comprises a nominal guide rail, wherein both ends of the nominal guide rail are fixed to both ends of a measuring platform by supporting plates, and the nominal guide rail is provided with a nominal sliding block connected witha measuring box through a fixed rod. The measuring box is internally divided into a first cavity and a second cavity through a partition plate, a point light source shooting directly down is arrangedon the top of the inside of the first cavity, a first reflector is further arranged in the first cavity, a second reflector is fixed to the inside of the second cavity, and a reading plate is fixed tothe top of the second cavity. According to the device for measuring the straightness of the guide rail and the measuring method thereof, the straightness of the guild rail is detected through light rays, the change of the straightness of the guide rail is quickly fed back to the reading plate through light rays, no waiting time is required, observing is convenient, and the detection efficiency ishigh; and the device for measuring the straightness of the guide rail and the measuring method thereof can be used for straightness measurement of guide rails with different sizes, and the applicability of the device is high.
Description
technical field [0001] The invention belongs to the technical field of guide rail detection, and in particular relates to a device for measuring the straightness of a guide rail and a measuring method thereof. Background technique [0002] In the guide rail production process, it is necessary to detect the straightness of the guide rail, such as the patent application number CN201020643140.8, which discloses a hollow guide rail straightness detection device, including a detection platform and a support frame arranged below the detection platform. The section of the detection platform is L-shaped, including a detection side plane and a detection upper plane perpendicular to each other, and the detection platform is fixed on a supporting frame. The structure design of the above-mentioned device is simple and reasonable, which can realize the straightness detection of the hollow guide rail, and can detect the straightness of the outer top surface of the guide edge and the guide...
