The second rotary driver 7a is a servo motor; because the first detection workbench 3 and the second detection workbench 4 have the same structure, the first clamping roller 5, the second clamping roller 6, the rotary driving mechanism 7 and the elastic mechanism 8 are respectively arranged on the first detection workbench 3 and the second detection workbench 4, the controller sends a signal to the second rotary driver 7a, the output shaft of the second rotary driver 7a rotates after receiving the signal, the output shaft of the second rotary driver 7a drives the driving wheel 7b to coaxially rotate, the torque force is transmitted to the driven wheel 7c through the transmission effect of the transmission belt 7d, the driven wheel 7c drives the first clamping roller 5 to rotate at the upper ends of the first detection workbench 3 and the second detection workbench 4, and the first clamping roller 5 generates friction force with the side wall of the bearing bush when rotating, so that the bearing bush is pushed to automatically advance between the first clamping roller 5 and the second clamping roller 6, and automatic comprehensive detection is realized.
The elastic mechanism 8 comprises a yielding hole 8a, a fixed support 8b, a sliding seat 8c, a counter bore 8d, a guide rail 8e, a guide screw 8f, a return spring 8g and an adjusting bolt 8 h; the abdicating hole 8a is arranged at the matching position of the first detection workbench 3, the second detection workbench 4 and the second clamping roller 6, the lower end of the second clamping roller 6 passes through the abdicating hole 8a and is fixedly connected with the sliding seat 8c of the elastic mechanism 8, the fixed support 8b is fixedly arranged at the bottom end of the frame 1, the counter bores 8d are symmetrically arranged at the two sides of the sliding seat 8c, the guide rail 8e is fixedly arranged at the bottom end of the frame 1 and is arranged in the direction of the first detection workbench 3, the displacement direction of second test table 4 is unanimous, and seat 8c top and the guided way 8e sliding connection slide, and 8f one end of lead screw and 8b lateral wall fixed connection of fixed bolster, the 8f other end of lead screw are pegged graft with counter bore 8d, and reset spring 8g cup joints on 8f of lead screw and is located between 8b lateral walls of fixed bolster 8f and the seat 8c that slides.
The receding hole 8a is used for providing a space for the movement of the second grip roller 6, and the fixed bracket 8b provides a support for the main body of the entire elastic mechanism 8. When there is an abnormality in the curvature of the shoe, the force between the first and second nip rollers 5, 6 changes. When the force between the first clamping roller 5 and the second clamping roller 6 is increased, the second clamping roller 6 is pushed to be away from the first clamping roller 5, at the moment, the second clamping roller 6 drives the fixed support 8b to be away from the first clamping roller 5 along the direction of the guide rail 8e, the guide screw 8f on one side of the fixed support 8b, which is away from the first clamping roller 5, gradually penetrates into the counter bore 8d on the side, so that the reset spring 8g on the guide screw 8f on the side is compressed, and meanwhile, the fixed support 8b on the side abuts against the alarm mechanism 9 to trigger the alarm mechanism 9 to send an alarm signal to the controller. When the workpiece with abnormal radian passes through, the elastic mechanism 8 can reset under the action of the reset spring 8 g; on the contrary, when the force between the first and second pinch rollers 5, 6 is reduced, the second pinch roller 6 approaches the first pinch roller 5, and the triggering principle of the alarm mechanism 9 by each component is the same as that when the component is far away. Therefore, the alarm mechanism 9 is triggered to send an alarm signal to the controller as long as the radian of the split bearing bush workpiece is abnormal.
And the guide screw 8f is fixedly connected with the side wall of the fixed support 8b through an adjusting bolt 8h in a threaded manner.
The detection accuracy is further ensured by fine horizontal adjustment of the position of the entire elastic mechanism 8 by adjusting the depth to which the adjusting bolt 8h is screwed into the lead screw 8 f.
The alarm mechanism 9 comprises a microswitch 9 a; the micro switches 9a are symmetrically arranged at two sides of the fixing part of the elastic mechanism 8, and when the elastic mechanism 8 generates abnormal movement, the micro switches 9a are extruded, and the micro switches 9a are electrically connected with the controller.
The micro-switch 9a is symmetrically arranged at two sides of the fixed part of the elastic mechanism 8, no matter which direction of linear displacement is generated at the movable part of the elastic mechanism 8, the micro-switch 9a can be extruded, and when the micro-switch 9a is extruded, a signal can be sent to the controller to trigger an alarm.
The alarm mechanism 9 further comprises an alarm, and the alarm is electrically connected with the controller.
When the elastic mechanism 8 triggers the alarm mechanism 9, the alarm mechanism 9 sends an alarm signal to the controller, and the controller sends a signal to the alarm of the alarm mechanism 9 to remind workers in time, so that unqualified products are prevented from being mixed into qualified products, and the factory yield is reduced.
The working principle of the invention is as follows:
the size data that the staff measured the subdivision formula axle bush work piece that needs to measure earlier, then sends data to the controller, and the controller sends the instruction according to the data that receive and gives size adjustment mechanism 2, and size adjustment mechanism 2 drives first detection table 3 and second detection table 4 and keeps away from each other or be close to with the perpendicular angle in order to adapt to the measurement of the axle bush of different sizes. After the size adjusting mechanism 2 finishes adjusting, the worker clamps the head end and the middle part of the bent split bearing bush at the two ends of the split bearing bush respectively by using the first clamping roller 5 and the second clamping roller 6 on the first detection workbench 3 and the second detection workbench 4, and the bearing bush acts on the second clamping roller 6 by the reaction force generated to the first clamping roller 5 and the second clamping roller 6 so that the distance between the second clamping roller 6 and the two sides of the elastic mechanism 8 is within the range of a normal value. The operator then sends a signal via the controller to the rotary drive mechanism 7 on the first inspection station 3 and the second inspection station 4. The rotary driving mechanism 7 receives a signal and then drives the first clamping roller 5 to rotate, the first clamping roller 5 orders the bearing bush to move along the radian of the first clamping roller 5 through friction, and at the moment, a worker does material receiving work at the head end of the bearing bush or places an automatic material receiving device to automatically receive materials. When the radian of the bearing bush is a standard radian, the second clamping roller 6 only plays a role in fixing and clamping the bearing bush, but when the radian of the bearing bush is abnormal, the acting force generated by the bearing bush on the first clamping roller 5 and the second clamping roller 6 changes, so that the first clamping roller 5 and the second clamping roller 6 are close to each other or far away from each other, and the first clamping roller 5 is fixed with the first detection workbench 3 and the second detection workbench 4 in the radial direction, so that only the second clamping roller 6 can move. No matter the second clamping roller 6 is close to or far away from the first clamping roller 5, the elastic mechanism 8 can move towards one side of the first clamping roller to enable the distance value to be abnormal, so that the alarm mechanism 9 is triggered, the alarm mechanism 9 sends a signal to the controller after being triggered, and the controller records and reminds workers to take out unqualified products to avoid mixing with the qualified products. The structure of the elastic mechanism 8 allows the triggering accuracy to be adjusted manually to further ensure the accuracy of the measurement. All be equipped with the bearing in order to improve equipment's stability and fluency in the clearance fit department that supplies rotary motion everywhere on the equipment.
