Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical detection, and relates to a test bench for concentricity detection. Background Art
[0002] In the current industrial manufacturing field, the detection of concentricity is crucial for ensuring the smooth operation of rotating components and reducing wear. In many industries such as aeroengines, automobile manufacturing, and machining, high-precision concentricity detection is an essential part of the production process.
[0003] There are various methods for detecting concentricity, including using coordinate measuring machines, dial indicators, laser sensors, etc. However, these traditional detection methods often have some limitations. For example, they are complex to operate, inefficient, costly, or unable to perform multi-station simultaneous detection. In addition, some devices cannot maintain horizontal during the detection process, resulting in errors in the detection results. There are also some methods that cannot visually present the results during detection, increasing the detection steps and reducing the efficiency. Content of the Utility Model
[0004] The utility model provides a test bench for concentricity detection to solve the problems of the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A test bench for concentricity detection, comprising: a positioning table and a detection mechanism. The positioning table includes a rotating base, a rotating table rotatably arranged in the rotating base, and a rotating bearing arranged between the rotating base and the rotating table. One side of the rotating base is arranged on a detection installation platform, and a locking groove is arranged at the upper end. A sliding pin is slidably arranged in the locking groove, and the detection mechanism is arranged on the detection installation platform.
[0006] Further improvement, the detection mechanism includes a mounting base fixedly arranged on the detection installation platform, a mounting rod fixedly arranged on the mounting base, a first locking seat arranged at the upper end of the mounting rod, a first adjusting rod fixedly arranged on the first locking seat, a second locking seat slidably arranged on the first adjusting rod, and a dial indicator rotatably arranged on the second locking seat.
[0007] Further improvement, both the first locking seat and the second locking seat include a sliding seat and a locking threaded rod for locking.
[0008] Further improvement, multiple groups of rotating bearings are arranged.
[0009] Further improvement, a positioning groove is arranged at the lower end of the rotating base.
[0010] Compared with the prior art, the utility model has the following beneficial effects: The utility model includes a positioning table and a detection mechanism. The positioning table is composed of a rotating base, a rotating table and a rotating bearing. The rotating base provides a stable platform. The rotating table can rotate around the rotating base, and the two are connected by a rotating bearing to ensure the smooth rotation of the rotating table. The upper end of the rotating base is provided with a locking groove for locking the position of the rotating table during the detection process. A sliding pin is slidably arranged in the locking groove. By moving the sliding pin, the rotating table can be easily locked or unlocked, so as to conveniently fix or release the rotating table before and after the detection. When performing concentricity detection, the component to be measured is placed on the rotating table. First, the rotating table is locked by the sliding pin, and the dial indicator is zeroed. Secondly, the locking of the rotating table is released, and the rotating table is rotated. The radial runout of the component to be measured is measured with the dial indicator, so as to obtain the concentricity data, which improves the measurement accuracy and makes the operation process more simple and fast.
