Description

Bearing noise detection equipment Technical Field The application relates to the technical field of bearing production, in particular to bearing noise detection equipment. Background The bearing is used as a core basic part of mechanical equipment, the production process of the bearing comprises a plurality of precise links from raw material selection, forging, turning, heat treatment, grinding and the like, and each step plays a decisive role in the final quality of the bearing. After a series of processing procedures are completed, in order to ensure the lubricating performance of the bearing in the running process, the bearing grease is required to be added by utilizing a bearing grease adding production line, and a proper amount of special lubricating grease is filled into the bearing. However, due to potential problems such as scratch of the raceway surface, insufficient precision of the rolling elements, assembly deviation, etc. which are often difficult to directly identify by naked eyes during the production process, the problems are expressed in the form of noise during the operation of the bearing. Therefore, in order to ensure the quality stability and the use reliability of the factory bearing, after the grease adding process, strict noise detection is required to be carried out on each batch of bearings by using professional bearing noise detection equipment, whether the bearings have quality defects or not is judged according to detection results, and unqualified products are screened. The bearing noise detection equipment is a precise instrument specially used for detecting bearing running noise, and the core detection component is a probe. The probes usually adopt high-sensitivity acoustic sensors or vibration sensors, can accurately capture tiny noise signals and vibration signals generated by the bearing in an analog running state, and the signal processing system can amplify, filter, analyze and the like the electric signals and convert the electric signals into quantifiable noise values or spectrograms. An operator can judge the noise level of the bearing according to a preset noise standard threshold value, and the qualified, suspicious and unqualified bearings are distinguished. Since a small amount of lubricating grease inevitably overflows to the bearing surface in the grease capping process, a layer of grease is often attached to the bearing surface after grease is added, and when the bearings with the grease are placed on a conveyor belt of noise detection equipment for conveying, the grease on the bearing surface is gradually attached to the conveyor belt along with the running of the conveyor belt. Along with the continuous progress of detection work, oil stains on the conveyer belt can be continuously piled up, and after long-term pile up, a layer of greasy dirt can be formed on the conveyer belt, and when follow-up bearing is carried on the conveyer belt, these greasy dirt are easy to be attached to the bearing surface, and after the greasy dirt attached to the bearing detection position, can produce the interference to the probe and catch bearing noise signal, on the one hand the greasy dirt can hinder the effective contact of probe and bearing surface, influence the transmission efficiency of signal, on the other hand, the greasy dirt can produce extra friction noise in the bearing operation process, and these noise can overlap with the noise signal of bearing itself, leads to the signal distortion that detection equipment received, and then leads to the testing result inaccurate to influence the precision that detection equipment was to the bearing. Disclosure of Invention The application aims to solve the problem that oil stains attached to the surface of a bearing can be attached to a conveying belt in the background art, and in long-term operation of equipment, the oil stains are accumulated on the conveying belt and can be attached to a bearing to be conveyed and detected later, so that the detection precision of the bearing is affected. The application adopts the following technical scheme for realizing the purposes: The utility model provides a bearing noise check out test set, includes the main body base, main body base upper end is fixed with the detection bin, detect the inside detecting element that is used for detecting the bearing that is provided with in bin, detect bin surface mounting has the guard gate, the conveyer belt is installed to main body base upper end, be fixed with the material loading guide rail on the conveyer belt, main body base upper end is installed and is used for carrying out the material shifting unit that shifts to the bearing, detect the bin side and seted up feed channel, detect the inside feeding element that is used for sending into the bearing toward detecting the inside feeding channel corresponding position of bin, be provided with between main body base and the conveyer belt and be used for carrying out the oil stain removal struc
