Description

Technical Field

[0001] The invention relates to the technical field of bearing detection instruments, in particular to an automatic rotation observation and analysis device for a bearing component. Background Art

[0002] At present, in bearing component research and development centers or manufacturers that produce and sell bearing components, when a bearing fails, professional inspectors are required to disassemble the bearing and observe and analyze each component of the bearing in order to detect and analyze the cause of the failure. Currently, when inspectors detect and analyze failed bearing components, they drive the bearing components to rotate through a single manual rotation method, and then observe the bearing components through a Keyence observation instrument, such as observing the inner ring groove or outer ring groove or steel ball surface to analyze the cause of the bearing failure. However, many problems may arise when rotating the bearing components manually. For example, manual rotation of the bearing components cannot comprehensively and continuously observe the bearing components, and cannot be driven and observed automatically, which greatly reduces the observation efficiency and detection accuracy, and affects the observation direction of the Keyence observation instrument. At the same time, the bearing components are placed on a V-table or a test table, which is very easy to shake, loosen, or shift during manual rotation, or collide with the Keyence observation instrument lens, thereby affecting the detection accuracy and analysis efficiency. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides an automatic rotation observation and analysis device for a bearing component, in order to solve the problem in the prior art that detection of a failed bearing component requires manual driving of the bearing component and the detection accuracy is low.

[0004] In order to achieve the above-mentioned purpose, the present invention provides an automatic rotation observation and analysis device for a bearing component, comprising a base, a turntable and a driving member for driving the turntable to rotate axially are provided on the base, an inner clamp for fixing the inner ring of an external bearing to be tested and an outer clamp for cooperating with the inner clamp to fix the outer ring of the external bearing to be tested are provided on the surface of the turntable, and an adjustment structure is provided on the turntable for adjusting the distance between the inner clamp and the outer clamp to adapt to the inner ring or outer ring of the external bearing to be tested of different diameters.

[0005] The advantages of adopting the above technical scheme are: placing the bearing component to be inspected on the surface of the turntable, and when the bearing component to be inspected is the inner ring of the bearing, it can be fixed by an inner clamp so that the inner diameter and outer diameter grooves of the inner ring are exposed, and when the bearing component to be inspected is the outer ring of the bearing, the outer ring of the bearing can be placed between the inner clamp and the outer clamp and fixed by the inner clamp and the outer clamp. After the bearing component is fixed, the turntable is driven to rotate axially by the driving member, so that the rotation of the turntable drives the bearing component to rotate synchronously, thereby realizing the automatic rotation of the bearing component, so that when the external detection instrument detects the groove of the bearing component, the bearing component will not shake or loosen, causing the detection accuracy and detection efficiency to be affected, and at the same time, the automatic driving of the bearing component to be inspected is realized to improve the detection efficiency and detection accuracy; in the above technology, the distance between the inner clamp and the outer clamp can be adjusted by adjusting the structure to adapt to bearing components of different diameters, thereby increasing the detection range.

[0006] The invention further provides that: the turntable is hollow and has a rotating cavity, the outer clamp is composed of a plurality of outer clamps, and the plurality of outer clamps are circumferentially evenly distributed on the outer edge of the turntable, and the inner clamp is provided with an inner clamp corresponding to each outer clamp position, and the radial cross-sections of the outer clamp and the inner clamp are both arc-shaped. A slide rail is provided in the rotating cavity corresponding to each outer clamp position, and a through hole is opened on the outer peripheral wall of the turntable corresponding to each slide rail position, and each of the slide rails penetrates through its corresponding through hole and is connected to the corresponding outer clamp position, and a slide groove is opened on the slide rail along its length direction, and a slide plate is movably arranged in the slide groove, and an adjustment groove is opened on the surface of the turntable corresponding to each slide groove position, and the plurality of slide plates are arranged one by one in correspondence with the plurality of inner clamps, and each of the slide plates is connected to a connecting plate between the corresponding inner clamp plate, and the connecting plate is arranged perpendicular to the slide plate, and the outer peripheral wall of each inner clamp plate is gap-matched with the inner peripheral wall of the corresponding outer clamp plate to form a accommodating groove.

[0007] The benefits of adopting the above technical solution are: in the above technology, the radial cross-sections of the outer plate and the inner plate are both arranged in an arc shape, so as to fit the inner diameter surface or the outer diameter surface of the bearing component, and a plurality of inner plates and a plurality of outer plates are evenly distributed in the annular direction, so as to expose the inner diameter surface or the outer diameter surface of the bearing component so that it can be inspected by external detection instruments.

[0009] The benefits of adopting the above technical solution are: when it is necessary to adjust the spacing between the inner plate and the outer plate, the operator rotates the adjusting shaft so that the adjusting shaft drives the secondary gear to rotate axially. Because the secondary gear is meshed with the main gear, when the secondary gear rotates, it will drive the main gear to rotate synchronously. The rotation of the main gear will drive several slave gears to rotate synchronously. A connecting shaft is connected between the slave gear and the adjusting gear, so that several adjusting gears rotate synchronously. Because the adjusting gear is meshed with the adjusting tooth groove, when the adjusting gear rotates, it will drive the slide plate to slide in the slide groove, thereby realizing the adjustment of the relative position between the inner plate and the turntable, thereby realizing the adjustment of the spacing between the inner plate and the outer plate, and then facilitating the fixing and limiting of bearing components of different diameters, thereby ensuring that the bearing components will not shake or loosen when they rotate synchronously with the rotation of the turntable.

[0011] The advantages of adopting the above technical scheme are: after the adjustment of the adjusting shaft is completed, the operator can insert the connecting sleeve to make the connecting hole and the limiting shaft plug-in, and when the connecting hole and the limiting shaft are plug-in, the third tooth groove and the fourth tooth groove are plug-in and meshed, and the relative fixation of the limiting shaft and the connecting sleeve is achieved due to the setting of the third tooth groove and the fourth tooth groove, and when the connecting sleeve is inserted into the limiting hole, the first tooth groove and the second tooth groove are plug-in and meshed, thereby achieving relative fixation between the connecting sleeve and the limiting sleeve, thereby achieving the limitation of the limiting shaft, avoiding the rotation of the limiting shaft to drive the adjusting shaft to rotate in the adjusting hole, and thus avoiding the movement of several slides resulting in the failure of the inner clamp to limit the bearing component, and at the same time avoiding the shaking or loosening of the adjusting shaft affecting the limiting strength of the inner and outer clamps to the bearing component. In the above technology, the adjusting shaft is threadedly connected to the adjusting hole, which further improves the stability and limiting strength of the sub-gear after rotation.
