Portable bearing rotating precision comprehensive detection platform

Abstract

The invention discloses a portable bearing rotating precision comprehensive detection platform which can quickly identify bearing key indexes. The portable bearing rotating precision comprehensive detection platform comprises bearing clamping diameter-adjustable structure units which are arranged to be in longitudinal symmetry, a dynamic gap removing unit, a gap removing component and a portable measuring clamping accessory. Each bearing clamping diameter-adjustable structure unit comprises a disk, three radial adjusting rails with the same value, a bearing supporting plate and a limiting rod unit. The portable bearing rotating precision comprehensive detection platform can achieve three-point centering type clamping, enables the gap between the inner diameter part and the outer diameter part to be removed, and is high in testing precision, accurate, fast, low in requirement for a testing environment and convenient to popularize. The portable bearing rotating precision comprehensive detection platform is not rusted and free of maintaining, small in size and easy to carry, and the weight of the platform is about 1kg. Further, the radial adjusting rails and the limiting rod units adjust in a sliding mode, and quick measuring of various specifications of bearing rotating precision indexes to be measured in the rotating gap-removing state can be achieved. The portable bearing rotating precision comprehensive detection platform is small in manufacturing cost, low in operation difficulty, and capable of greatly shortening the detection period, lowering cost, and meeting the regular demands for timeliness and small cost of enterprises.

Description

technical field [0001] The invention relates to a bearing detection device; in particular, a portable comprehensive detection platform for bearing rotation accuracy, which can be widely used in aerospace, navigation, automobile, electronics, radar and other military and civilian product fields that circulate, use and have detection requirements for bearings. all relevant links. Background technique [0002] Bearing rotation accuracy is the lifeline of bearings, and it is the key to assessing the quality control and cost ratio of bearing enterprises. Especially in many indicators of bearings, the quality of rotation accuracy basically means the choice between its identity and whether to buy and use. [0003] After searching the literature at home and abroad, however, there are few research materials on the bearing rotation accuracy detection device at present, which are only reflected in the national standard.

Problems solved by technology

[0004] First, it is difficult to promote and popularize: the device must be equipped with a wide variety of high-precision mandrels, bosses, steps, metal counterweights and other auxiliary facilities that match the mandrel for the inner and outer diameters of the bearings. The configuration requirements are also high: a professional environment and considerable configuration are required, resulting in the formation of comprehensive costs such as labor, site, maintenance, and management, resulting in higher dilution costs

Therefore, the existing bearing testing devices are basically only configured in professional appraisal institutions

[0005] Second, it cannot meet the regular needs of enterprises for timeliness and low cost: For enterprises using bearings, the goal is to do a good job of controlling, that is, to grasp the timing of bearing inspection, and the focus is on the purchase of bearings (especially the batch Sexual purchase), or the bearing is judged and tested before installation and maintenance; it needs to be tested conveniently and quickly

[0006] To sum up, due to the scarcity of bearing testing devices in society and the high threshold for departments equipped with testing devices, the bearing market is flooded with counterfeit and inferior bearings, and timely supervision cannot be carried out.
