Description

Technical Field

[0001] The utility model relates to the technical field of taper bearing thickness measurement, and particularly relates to an automatic shaft-recognizing rotating device for a differential taper bearing. Background Art

[0002] Automobile differentials mostly use taper bearings to support the shafting. High requirements are placed on the product quality of the taper bearings, and the thickness of the taper bearings needs to be measured after press-fitting. Most of the existing measurement methods are manual contact types, with low measurement efficiency and easy generation of measurement errors.

[0003] Based on this, the utility model proposes an automatic shaft-recognizing rotating device for a differential taper bearing, which measures the thickness of the taper bearing through non-contact operation to improve the measurement efficiency and reduce the measurement error. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned prior art, the utility model provides an automatic shaft-recognizing rotating device for a differential taper bearing to solve the above technical problems.

[0005] An automatic shaft-recognizing rotating device for a differential taper bearing includes a support column, a rotating motor, and a measurement component support frame. The support column is rotatably sleeved with a gear turntable. A material trough is slidably connected to the top of the gear turntable. The output shaft of the rotating motor is fixedly connected with a disc gear, and the outer circumference of the gear turntable meshes with the disc gear.

[0006] The measurement component support frame is equipped with a vertical electric telescopic arm and a horizontal electric telescopic arm. The vertical electric telescopic arm is connected with a displacement sensor through a mounting block. The horizontal electric telescopic arm is fixedly connected with a shaft stopper. The material trough abuts against the main shaft of the shaft stopper. The gear turntable stops rotating. The vertical electric telescopic arm moves downward. The distance from the displacement sensor to the top surface of the lower gear turntable is S1. The horizontal electric telescopic arm extends. The sub-shaft of the shaft stopper pushes the material trough to slide under the displacement sensor. The distance from the displacement sensor to the top surface of the lower taper bearing is S2. The thickness of the taper bearing = S1 - S2.

[0007] Further, the mounting block is connected with a sliding stop through a return spring. When the vertical electric telescopic arm extends, the sliding stop compresses the return spring and abuts against the taper bearing.

[0008] Further, the measurement component support frame is provided with an extension frame, and the extension frame is equipped with an auxiliary electric telescopic arm for pushing the material trough to slide back to its original position. The included angle between the center line of the auxiliary electric telescopic arm and the center line of the horizontal electric telescopic arm is 120°.

[0009] Further, the gear turntable is provided with a slide rail, and the material trough is provided with a slider matching the slide rail.

[0010] Furthermore, the length of the split shaft is greater than half of the outer diameter of the material trough.

[0011] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects of the present utility model include:

[0012] First, measure the distance from the displacement sensor to the top surface of the lower gear turntable, then push the material trough to slide below the displacement sensor, and measure the distance from the displacement sensor to the top surface of the lower tapered bearing. The thickness of the tapered bearing can be obtained through the difference between the two. The displacement sensor does not contact the tapered bearing, reducing the intensity of manual measurement, improving the measurement efficiency, and reducing manual measurement errors;

[0013] Through the rotation of the gear turntable, feeding, measuring, and discharging are carried out in an orderly manner, reasonably arranging the production order, and improving the work efficiency;

[0014] The stop shaft cooperates with the material trough at the edge position of the gear turntable to achieve automatic stopping of the gear turntable. Description of the Drawings

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, other implementation manners or equivalent replacements obtained by those skilled in the art without making creative efforts are within the protection scope of the present utility model.

[0020] As Figures 1-3As shown in the figure, an automatic shaft-identifying rotating device for a differential cone bearing includes a support column 1, a rotating motor 2, and a measuring component support frame 3. The support column 1 is rotatably sleeved with a gear turntable 4. The top of the gear turntable 4 is slidably connected with a material trough 5. The output shaft of the rotating motor 2 is fixedly connected with a disc gear 6, and the outer circumference of the gear turntable 4 meshes with the disc gear 6;

[0021] The measuring component support frame 3 is equipped with a vertical electric telescopic arm 7 and a horizontal electric telescopic arm 8. The vertical electric telescopic arm 7 is connected with a displacement sensor 10 through a mounting block 9, and the horizontal electric telescopic arm 8 is fixedly connected with a shaft stopper 11;

[0022] Stations A, B, and C are respectively used for feeding, measuring, and discharging. Feeding at station A and taking out at station C can be completed by a manipulator or manually; when operating manually, the disc gear 6 is arranged between stations B and C or between stations A and B, facilitating the simultaneous control of stations A and C; the cone bearing is loaded into the material trough 5 at station A, and the disc gear 6 drives the gear turntable 4 to rotate. When the main shaft of the shaft stopper 11 intercepts the material trough 5 containing the cone bearing, the gear turntable 4 stops rotating. The vertical electric telescopic arm 7 moves downward, and the distance from the displacement sensor 10 to the top surface of the lower gear turntable 4 is S1. The horizontal electric telescopic arm 8 extends, and the sub-shaft of the shaft stopper 11 pushes the material trough 5 to slide below the displacement sensor 10. The distance from the displacement sensor 10 to the top surface of the lower cone bearing is S2. The thickness of the cone bearing = S1 - S2; when measuring at station B, feeding continues at station A; the vertical electric telescopic arm 7 contracts, the horizontal electric telescopic arm 8 contracts, the gear turntable 4 continues to rotate, the shaft stopper 11 intercepts the next material trough 5 reaching station B, the vertical electric telescopic arm 7 extends again, and the displacement sensor 10 measures the distances from the displacement sensor 10 to the top surface of the lower gear turntable 4 and the top surface of the cone bearing respectively. At this time, feeding continues at station A, and the measured cone bearing is taken out at station C.

[0023] Wherein, the mounting block 9 is connected with a sliding stop frame 13 through a return spring 12. When the vertical electric telescopic arm 7 extends, the sliding stop frame 13 compresses the return spring 12 and abuts against the cone bearing; the sliding stop frame 13 does not cover the measuring point of the displacement sensor 10, and the sliding stop frame 13 restricts the top of the cone bearing to prevent the cone bearing from shaking when moving with the material trough 5 and affecting the measurement of the displacement sensor 10.

[0024] Wherein, the measuring component support frame 3 is provided with an extension frame 14, and the extension frame 14 is equipped with an auxiliary electric telescopic arm 15 for pushing the material trough 5 to slide back to its original position. The included angle between the center line of the auxiliary electric telescopic arm 15 and the center line of the horizontal electric telescopic arm 8 is 120°, that is, the auxiliary electric telescopic arm 15 faces station C, so that the material trough 5 reaching station C slides back to the edge position of the gear turntable 4, facilitating the taking out by a manipulator or manually, and also facilitating the material trough 5 to be intercepted by the shaft stopper 11 when it rotates to station B again.

[0025] Among them, the gear turntable 4 is provided with a slide rail 16, and the material chute 5 is provided with a slider that cooperates with the slide rail 16. Each single material chute 5 corresponds to two slide rails 16.

[0026] Among them, the length of the split shaft is greater than half of the outer diameter of the material chute 5.

Obviously, many modifications and changes can be made according to the content of this specification.
