Specific embodiments

[0025] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be further introduced in detail below in conjunction with the drawings.

[0026] As Figures 1-6 The utility model discloses a bearing roller roundness detection device, including roundness detector 1 and the conveying belt 2 for conveying bearing roller in detection station, still include the jacking mechanism 4 for jacking bearing roller, including linear array setting in the fixed seat 3 of conveying belt 2;

[0027] Circumferential array, and along the radial sliding setting in the fixed seat 3 of sliding seat 6;

[0028] The centering rod 5 of rotation setting on sliding seat 6, it is tangent to bearing roller and deflection towards the axle center;

[0029] Setting in the fixed seat 3, and with the extrusion sliding seat 6 of jacking mechanism 4 jacking transmission rod 7.

[0030] Specifically, bearing roller falls on the fixed seat 3, is driven to detection station subsequently by conveying belt 2, and infrared inductor is arranged on detection station to initiative response bearing roller in place, subsequently sends signal to jacking mechanism 4 to make jacking mechanism 4 jacking bearing roller to roundness detector 1 in detection, the electronic component involved in the above-mentioned technology is all the technical knowledge of the person skilled in the art, and here is not repeated.

[0031] Further, the end of the centering rod 5 is fixedly provided with a pressing part 52, and the sliding seat 6 is provided with a first spring 66. During the rolling of the bearing roller on the fixed seat 3, the bearing roller slides between the centering rods 5 and is actively erected under the guidance of the inclined centering rods 5, and then the side surface of the bearing roller abuts against the pressing part 52 fixedly arranged at the end of the centering rod 5, the pressing part 52 is deflected and drives the whole centering rod 5 to deflect, thereby fixing the bearing roller, and then the jacking mechanism 4 jacks up the bearing roller, and the bearing roller is kept in a vertical state and is lifted into the roundness detector 1 under the pressing of the centering rod 5, and meanwhile, the jacking mechanism 4 drives the transmission rod 7 to move upwards, the transmission rod 7 is in sliding fit with the sliding seat 6 and pushes the sliding seat 6 to slide in the radial direction during the upward movement, the sliding seat 6 drives the centering rod 5 to move away from the bearing roller, the pressing part 52 of the centering rod 5 is deflected and still keeps the state of pressing the bearing roller, so that the bearing roller is separated from the clamping of the centering rod 5 and is detected in the roundness detector 1.

[0032] In the above technology, the bearing roller slides between the centering rods 5 and is actively erected under the guidance of the inclined centering rods 5, the pressing part 52 is deflected and drives the whole centering rod 5 to deflect, thereby fixing the bearing roller, so that the bearing roller is kept in a vertical state in the fixed seat 3 and cannot be deflected during the jacking, and the interference in the detection process can be reduced.

[0033] As a further provided embodiment of the utility model, the cam 9 which is rotationally arranged in the fixed seat 3 and is provided with a torsional spring is further included, and the cam 9 is used for pushing the centering rod 5.

[0034] Specifically, the torsional spring on the cam 9 is used for deflecting the long shaft part of the cam 9 to the shaft center, and during the deflection, the cam 9 is in sliding fit with the centering rod 5 to make the centering rod 5 clamp the bearing roller, and the elastic force of the torsional spring further guarantees the vertical state of the bearing roller.

[0035] As a further provided embodiment of the utility model, the sliding rod 61 which is slidably arranged in the sliding seat 6 in the vertical direction and is in sliding fit with the cam 9 is further included.

[0036] Specifically, the centering rod 5 is provided with a blocking piece 51 which is in blocking fit with the sliding rod 61, and the blocking piece 51 is provided with an opening for the sliding rod 61 to pass through, the first end of the sliding rod 61 is provided with an inclined block 62 which is in sliding fit with the inclined surface 91 fixedly arranged on the cam 9, and the inclined block 62 is provided with an opening below, the second end of the sliding rod 61 is fixedly provided with a protruding block 65, and the sliding rod 61 is pushed by the second spring 67 fixedly arranged in the sliding seat 6. In the default state, the blocking piece 51 blocks the protruding block 65, so that the sliding rod 61 is kept at the initial height, at this time, the second spring 67 is charged, and the inclined block 62 at the initial height abuts against the inclined surface 91, so that the torsional spring on the cam 9 is deformed, and the cam 9 has a tendency to deflect towards the shaft center.

[0037] When the centering rod 5 is deflected with the bearing roller tangent, the blocking piece 51 is misaligned with the protrusion 65, at this time, the opening on the blocking piece 51 corresponds to the protrusion 65, so that the sliding rod 61 is not blocked by the blocking piece 51, and the sliding rod 61 moves up under the push of the second spring 67, so that the opening 63 corresponds to the inclined surface 91, and the cam 9 is not blocked and actively deflected under the release of the torsional spring.

[0038] As further provided by the utility model, the elastic member is arranged on the sliding seat 6 and is used for keeping the centering rod 5 at a default angle.

[0039] Specifically, the elastic member is used for extending the abutting portion 52 of the centering rod 5 inside the fixed seat 3, and in the state that the centering rod 5 is tangent to the bearing roller, the opening of the elastic member is reduced, thereby playing a buffering role between the centering rod 5 and the fixed seat 3, and when the bearing roller falls, the impact force during the falling can be reduced, thereby avoiding damage to the bearing roller.

[0040] As further provided by the utility model, the buffer pad 8 is slidably arranged in the fixed seat 3, the transmission rod 7 is fixedly connected with the buffer pad 8, and the one-way clamping piece 72 is further arranged on the buffer pad 8 and is in blocking and releasing cooperation with the sliding rod 61.

[0041] Specifically, the pull rod 71 is fixedly arranged on the buffer pad 8, and the one-way clamping piece 72 is arranged on the pull rod 71. The jacking mechanism 4 jacks up the bearing roller and drives the transmission rod 7 to move up, the transmission rod 7 is in sliding cooperation with the sliding seat 6, and in the process of moving up, the transmission rod 7 pushes and drives the sliding seat 6 to slide along the radial direction, and simultaneously drives the one-way clamping piece 72 to move up. Since the one-way clamping piece 72 is an elastic structure, in the process of moving up, the one-way clamping piece 72 is folded after being pressed by the blocking piece 64 and then is unfolded above the blocking piece 64. The sliding seat 6 drives the centering rod 5 to move away from the bearing roller, so that the bearing roller enters the roundness detector 1, and after the detection is completed, the bearing roller is taken out, the jacking mechanism 4 moves down, the buffer pad 8 falls due to gravity and drives the pull rod 71 to fall, the pull rod 71 drives the one-way clamping piece 72 to abut against the blocking piece 64, at this time, the one-way clamping piece 72 drives the blocking piece 64 and the sliding rod 61 to slide down, and in the process of sliding down, the sliding rod 61 drives the inclined block 62 to slide with the inclined surface 91 on the cam 9, so that the cam 9 is restored.

[0042] The above only describes certain exemplary embodiments of the utility model by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various different ways without departing from the spirit and scope of the utility model. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the protection scope of the utility model claims.
