[0001] The invention relates to a bearing detection device and method, and in particular to a full-automatic bearing vibration detection device and method. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. They are widely used and very convenient to use. When they leave the factory, they are generally required to undergo vibration testing to meet different production accuracy requirements; for example, the invention patent with the authorization announcement number CN103439111B discloses a super-large bearing vibration noise quality testing machine.

[0003] The existing bearing vibration detection device has the following shortcomings:

[0012] The detection mechanism includes a vibration sensor, which is arranged on the upper limit card holder and detects downward;

[0013] The automatic unloading mechanism comprises an unloading channel arranged obliquely and an unloading driving mechanism for driving the bearing to transfer from the arc-shaped groove of the lower limit clamping seat to the unloading channel.

[0014] A preferred embodiment of the present invention, wherein the inner ring fixing mechanism includes a first side clamping mechanism and a second side clamping mechanism; the first side clamping mechanism includes a first side top column and a clamping rotation driving mechanism for driving the first side top column to rotate; the axis of the first side top column coincides with the center of the arc-shaped groove of the lower limit clamping seat; the side of the first side top column close to the arc-shaped groove is used to press against one of the side surfaces of the inner ring of the bearing to be detected, and a threaded hole is provided on the side of the first side top column close to the arc-shaped groove; the clamping rotation driving mechanism is composed of the detection rotation driving mechanism; the second side clamping mechanism includes a second side top column, a locking structure for locking the second side top column and a lateral driving mechanism for driving the second side top column to move lateraly; one end of the second side top column is provided with An external thread structure that cooperates with the threaded hole, and the other end of the second side top column is connected to the locking structure; a clamping structure is also provided on the second side top column, and the clamping structure is located between the external thread structure and the locking structure, and the clamping structure includes a through-hole that passes through the inner hole of the bearing to be tested and a clamping part for supporting the other side of the inner ring of the bearing to be tested; the locking structure includes an intermediate connecting seat and a locking cylinder, one end of the intermediate connecting seat is rotatably connected to the other end of the second side top column, and the other end of the intermediate connecting seat is fixedly connected to the driving end of the transverse driving mechanism; the intermediate connecting seat is connected to the frame through a transverse guide structure; a locking mounting hole is provided on the intermediate connecting seat; the locking cylinder is arranged in the locking mounting hole, and the telescopic rod of the locking cylinder is facing the side of the other end of the second side top column.

[0015] In a preferred embodiment of the present invention, the upper limit driving mechanism comprises an upper limit driving cylinder, a shell of which is fixed on a frame, and a telescopic rod of which is connected to the upper limit clamping seat.

[0016] A preferred embodiment of the present invention further comprises a load applying mechanism, wherein the load applying mechanism comprises an axial load applying mechanism and a radial load applying mechanism.

[0017] Furthermore, the axial load applying mechanism is composed of a lateral driving mechanism.

Furthermore, since the working conditions of the bearings are very complex, in order to simulate the working conditions of the bearings as close to reality as possible, this solution controls the oil of the two hydraulic cylinders through a hydraulic distributor (such as a proportional valve). Compared with the independent control mode, the advantage of this solution is that a hydraulic distributor is used, and the total pressure remains unchanged, which is equivalent to the total load of the bearing in actual operation remaining unchanged. During operation, the radial load and the axial load may change at the same time. At this time, it only needs to be controlled and adjusted through the hydraulic distributor to simulate the different states of axial force and radial force, so that the simulated working conditions are more realistic, which is conducive to obtaining more accurate test results.

[0022] In a preferred embodiment of the present invention, the detection rotation drive mechanism includes a detection rotation drive motor, which is connected to the first side top column via a flexible coupling. Through the above structure, the flexible coupling is connected to the bearing via the first side top column. During the test, the flexible coupling can transmit power and achieve a slight flexible misalignment, which is equivalent to a one-way connection with the bearing, so as not to offset the applied load force, making the test result more accurate.

Through the above structure, under the drive of the material unloading driving cylinder, the material unloading push block lifts the bearing and pushes it into the material unloading channel.

[0024] A fully automatic bearing vibration detection method comprises the following steps:

[0025] The bearing to be tested is placed vertically into the feeding channel, and the bearing to be tested automatically moves downward along the feeding channel; the bearing at the front enters the arc groove of the lower limit seat, and the second adjacent bearing is blocked by the retractable limit structure, waiting for the next round of testing;

[0026] The upper limit clamping seat is driven downward to approach the bearing to be tested below by the upper limit driving mechanism until the arc-shaped pressing groove of the upper limit clamping seat is pressed on the upper half of the bearing to be tested, thereby completing the clamping of the outer ring of the bearing; at this time, the bearing to be tested stands upright in front of the top column of the first side surface;

[0027] The second side top column is driven to move laterally close to the bearing to be tested by the lateral driving mechanism, and the external thread structure of the second side top column enters the inner hole of the bearing to be tested, and continues to move until the external thread structure of the second side top column contacts the threaded hole of the first side top column;

[0028] The locking cylinder drives the telescopic rod to press against the side surface of the other end of the second side top column, temporarily locking the second side top column, at which time the second side top column and the middle connecting seat are in a relatively static state;

[0029] The first side top column is driven to rotate in the corresponding direction by the clamping rotation driving mechanism, and the second side top column continues to move laterally until the clamping portion of the second side top column is pressed on the other side of the inner ring of the bearing to be tested, thereby clamping the inner ring of the bearing to be tested;

[0030] The detection operation is performed, the locking cylinder releases the lock on the second side top column, and the first side top column is driven to rotate by the detection rotation drive mechanism, and the first side top column drives the second side top column to rotate relative to the middle connecting seat, driving the bearing to be detected to rotate;

[0032] After the detection is completed, the locking cylinder locks the second side top column; the clamping rotation drive mechanism drives the first side top column to rotate in the opposite direction, so that the second side top column is automatically separated from the first side top column, and then the second side top column is driven to reset through the lateral drive mechanism; the upper limit clamping seat is driven to reset upwards through the upper limit drive mechanism, so that the bearing is exposed;

[0033] The bearing is driven by the unloading driving mechanism to transfer from the arc groove of the lower limit clamping seat to the unloading channel, so as to realize automatic unloading.
