Rotary scanning mechanism of profiler

Abstract

The invention relates to a rotary scanning mechanism of a profiler. The rotary scanning mechanism comprises a first supporting plate, a second supporting plate, a fixed connecting shaft, a contour scanner, and a driving member. The first supporting plate and the second supporting plate are horizontally provided on the side of the fixing plate. The fixed connecting shaft is provided on the second supporting plate. The contour scanner is provided at the lower end of the fixed connecting shaft and is used for measuring the member of a product. The driving member is provided on the first supporting plate and is used for driving the fixed connecting shaft to rotate. The fixed connecting shaft and the second supporting plate are rotatably connected. According to the rotary scanning mechanism ofa profiler, the fixed connecting shaft is provided with a stopping step and is installed with a locking nut, thereby eliminating the striking gap between the fixed connecting shaft and the second supporting plate, and avoiding the up-and-down movement of the fixed connecting shaft when rotating. At the same time, the thrust bearing and the end bearing ensure that the fixed connecting shaft will not sway horizontally, which ensures the coaxiality of the profiler during rotation, thereby ensuring the accuracy of the measurement.

Description

technical field [0001] The invention relates to the technical field of profilers, in particular to a profiler rotary scanning mechanism. Background technique [0002] A profiler is an instrument for testing and inspecting the contour, two-dimensional size, and two-dimensional displacement of an object. As a precision measuring instrument, it is widely used in automobile manufacturing and railway industries. It can measure the prime line shape and straight line of various precision mechanical parts degree, angle, convexity, logarithmic curve, groove depth, groove width and other parameters. The detection range of the profiler is short and the accuracy is high. When in use, the positioning must be accurate, it needs to be completely concentric and vertical, and it must prevent vertical movement. , so that the profiler can cover each position of the component to be tested. In traditional operations, most of them are manually rotated by the staff, but this method is prone to ax...

The detection range of the profiler is short and the accuracy is high. When in use, the positioning must be accurate, it needs to be completely concentric and vertical, and it must prevent vertical movement. , so that the profiler can cover each position of the component to be tested. In traditional operations, most of them are manually rotated by the staff, but this method is prone to axial series movement and radial swing, making the coaxiality changes, which affects the measurement results, so the profiler is required to have the function of rotation
