The invention discloses a device used for parallel positioning calibration of a vernier caliper of a rotating platform. The device includes a pedestal and a mobile platform, an image acquisition device arranged on the mobile platform and used for acquiring a parallel positioning image of the vernier caliper, a platform base achieving a stabilizing function, a round platform arranged on the platform base and capable of realizing relative rotation, a second driving device connected with a rotary encoder and arranged in an extending position on a right side edge of the platform base, a second transmission device capable of driving a third transmission device and the round platform to rotate, connector frames and a cylinder mounted on the round platform and used for fixing the vernier, high-precision scale lines and mark arrows engraved on the rotating platform and used for positioning and calculating the angle. The device provided by the invention uses the high-precision rotating platform to replace manual work, uses high-resolution image acquisition device to replace human eyes, observes and moves the vernier caliper to realize parallelism, thereby improving the precision of parallel positioning during automatic calibration of the vernier caliper, and the whole parallel positioning calibration process can realize automatic operation, thereby saving manpower, and improving the calibration efficiency.
Description
technical field [0001] Embodiments of the present invention relate to a parallel positioning verification device, in particular to a device for verifying the parallel positioning of a vernier caliper on a rotating platform. Background technique [0002] Vernier caliper (caliper for short) is a measuring tool for measuring length, inner and outer diameter, and depth. It is one of the most widely used and most important measuring tools in the machinery industry. In various fields, it is an essential tool for workers and inspectors in processing workshops. [0003] Enterprises or measurement departments that produce these vernier calipers need to perform performance verification on the indication error of these vernier calipers in accordance with the regulations formulated by relevant departments. The traditional verification method is done manually, which has the disadvantages of heavy workload, low efficiency, low precision, etc., and is easily affected by human error, resul...
