Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading of hub bearing flanges, in particular to a double-mechanical-arm loading and unloading device for hub bearing flanges. Background Art

[0002] Wheel hub bearings are components used in automobile axles to bear weight and provide precise guidance for the rotation of the wheel hub. They bear both axial and radial loads and are an important part of the load and rotation of the automobile. Wheel hub bearings mainly include wheel hub bearing flanges, outer flanges, two rows of rolling elements, and small inner rings. The center of the wheel hub bearing flange is provided with an axial hole structure protruding from the body, one side of which is long and the other side is short. The axial hole part on the longer side can be inserted into the outer flange.

[0003] The overall processing process of the hub bearing flange is similar to the processing process of the inner and outer rings of ordinary bearings. Therefore, in the prior art, the loading and unloading equipment for processing the inner and outer rings of ordinary bearings is usually directly applied to the processing of the hub bearing flange. However, since the hub bearing flange has a complex outer contour and is asymmetric, it is difficult to use a gripper to grab the hub bearing flange, and the processing efficiency is lower than that of the inner and outer rings of ordinary bearings. On the other hand, a single robotic arm is often used for the processing of bearings in the prior art, but when a single robotic arm is used to transfer the hub bearing flange, it is necessary to transfer the hub bearing flange to the unloading channel and then re-transfer the next hub bearing flange to the processing position for processing. At this time, if the single robotic arm loading and unloading equipment used to process the outer inner ring of ordinary bearings is directly applied to the processing of the hub bearing flange, the processing efficiency will be further reduced.

[0022] Example 1

[0023] A wheel hub bearing flange dual-arm loading and unloading device, such as Figure 1 and Figure 2As shown, it includes a panel 1 and an upper material arm 18 and a lower material arm 19 for transferring the hub bearing flange 6. The panel 1 is connected with an upper material channel 3 and a lower material channel 4 distributed up and down. The panel 1 is provided with a rotating mechanism for driving the upper material arm 18 and the lower material arm 19 to rotate. The upper material arm 18 can move between the upper material channel 3 and the processing position, and the lower material arm 19 can move between the processing position and the lower material channel 4. The upper material arm 18 includes a long arm 21, and the long arm 21 is provided with a The first gear-type air gripper 22, the unloading arm 19 includes a short arm 24, and the short arm 24 is provided with a second gear-type air gripper 25 capable of transferring the hub bearing flange 6, a loading baffle 2 is provided above the loading channel 3, and a unloading baffle 13 is provided between the loading channel 3 and the unloading channel 4. When the first gear-type air gripper 22 transfers the hub bearing flange 6 to the processing position and when the second gear-type air gripper 25 transfers the hub bearing flange 6 to the unloading channel 4, the loading baffle 2 and the unloading baffle 13 can both limit the hub bearing flange 6.

[0024] The rotating mechanism drives the loading arm 18 or the unloading arm 19 to rotate, the long arm 21 of the loading arm 18 rotates and drives the first gear-type air gripper 22 to rotate, the short arm 24 of the unloading arm 19 rotates and drives the second gear-type air gripper 25 to rotate, and the hub bearing flange 6 is transferred to the processing position by the first gear-type air gripper 22 at the material taking port of the loading channel 3 for processing, and is transferred to the unloading channel 4 by the second gear-type air gripper 25 after the processing is completed. When the hub bearing flange 6 is being processed, the first gear-type air gripper 22 releases the hub bearing flange 6, and the second gear-type air gripper 25 grabs the hub bearing flange 6 to ensure that it does not fall off when processing the hub bearing flange 6. At the same time, the first gear-type air gripper 22 goes to the loading channel 3 to transfer the next hub bearing flange 6 to the processing position, and the first gear-type air gripper 22 and the second gear-type air gripper 25 repeat this process. The loading baffle plate 2 is set to ensure that the first gear-type air gripper 22 does not fall off when transferring the hub bearing flange 6 from the loading channel 3 to the processing position, and the panel 1 and the loading baffle plate 2 can limit the hub bearing flange 6 to prevent the hub bearing flange 6 from tilting. The unloading baffle plate 13 can ensure that the second gear-type air gripper 25 does not fall off when transferring the hub bearing flange 6 from the processing position to the unloading channel 4, and the panel 1 and the unloading baffle plate 13 can limit the hub bearing flange 6 to prevent the hub bearing flange 6 from tilting. The first gear-type air gripper 22, the second gear-type air gripper 25 and the rotating mechanism are connected to a controller, and the controller controls the working process between them, wherein the specific connection method between the first gear-type air gripper 22, the second gear-type air gripper 25, the rotating mechanism and the controller is the prior art known to those skilled in the art, and will not be described in detail here.

[0025] In order to ensure that the loading arm 18 and the unloading arm 19 do not affect each other during the rotation process, the loading arm 18 is slightly away from the panel 1 relative to the unloading arm 19. However, in order to ensure that the first gear-type air gripper 22 of the loading arm 18 can smoothly grab the hub bearing flange 6 in the loading channel 3 and transfer it to the processing position, the first gear-type air gripper 22 is connected to the long arm 21 through the bottom plate 23. The bottom plate 23 and the long arm 21 are perpendicular to each other and face the panel 1. The bottom plate 23 can make the first gear-type air gripper 22 closer to the panel 1 while ensuring that the long arm 21 can be staggered with the unloading baffle 13 during the rotation process. The unloading baffle 13 is connected to the panel 1 through a connecting rod.

[0026] like Figure 4 As shown, the rotating mechanism includes two rotating components 31, the rotating component 31 includes a cylinder 27 vertically arranged on the back of the panel 1 and a connecting shaft 20 rotatably penetrated on the panel 1, the plunger of the cylinder 27 is connected with a rack 30, and the end of the connecting shaft 20 close to the cylinder 27 is fixedly sleeved with a gear 28 matched with the rack 30, and the other ends of the two connecting shafts 20 are respectively fixedly penetrated on the long arm 21 and the short arm 24. The cylinder 27 is provided with a sensor and a sensor bracket 29 for fixing the sensor, and the cylinder 27 is provided with a mounting plate, and the sensor bracket 29 is fixed to the mounting plate by fastening bolts, and a first strip hole for fastening bolts to cooperate is provided on the mounting plate, and a second strip hole matching with the first strip hole is provided on the sensor bracket 29, and the fastening bolts pass through the first strip hole and the second strip hole in sequence and are fastened by nuts.

[0027] The controller controls the operation of the two oil cylinders 27. When the oil cylinders 27 are started, the plungers of the oil cylinders 27 drive the rack 30 to move up and down, so that the gear 28 matched with the rack 30 rotates forward or reversely, and the connecting shaft 20 rotates forward or reversely, so that the long arm 21 or the short arm 24 sleeved on the connecting shaft 20 can move. The signal sent by the sensor can be received by the controller.

[0028] The above is a basic implementation method of the utility model, which can be further improved, optimized and limited on the basis of the above to obtain the following embodiments:

[0029] Example 2

[0030] This embodiment is an improved solution based on the embodiment 1. Its main structure is the same as that of the embodiment 1, and the improvements are as follows:

[0031] like Figure 3As shown, when the long arm 21 or the short arm 24 rotates, in order to prevent the rotation range from being too large, a first limit block 14 and a second limit block 17 are further provided on the panel 1, and the connecting shaft 20 fixedly penetrated on the long arm 21 is provided with a first limit rod 15, and the first limit rod 15 is located between the long arm 21 and the panel 1. During the movement of the long arm 21, the first limit block 14 can limit the first limit rod 15, and another connecting shaft 20 fixedly sleeved on the short arm 24 is provided with a second limit rod 26, and the second limit rod 26 is located between the short arm 24 and the panel 1. During the movement of the short arm 24, the second limit block 17 can limit the second limit rod 26.

The specific connection method is the existing technology known to those skilled in the art, and will not be described in detail here. When multiple hub bearing flanges 6 are on the loading channel 3, at least one dividing cylinder 7 is required for dividing the materials. In the utility model, two dividing cylinders 7 are provided. After the sensing needle of the loading sensing switch 10 is pushed by the hub bearing flange 6 near the discharge port of the loading channel 3, the first gear-type air claw 22 grabs the hub bearing flange 6 near the discharge port of the loading channel 3. At this time, the first dividing cylinder 7, the second dividing cylinder 7 and the blocking cylinder 9 are started, and the second stopper connected to the piston rod of the blocking cylinder 9 is against the hub bearing flange 6 near the discharge port of the loading channel 3. All the first stoppers are controlled by the piston rods of all the material dividing cylinders 7, and extend to prevent the remaining hub bearing flanges 6 from continuing to move. After the first gear-type air claw 22 grabs the hub bearing flange 6 near the discharge port of the feeding channel 3 and leaves, the sensing needle of the feeding induction switch 10 is reset. At this time, the piston rod of the material blocking cylinder 9, the piston rod of the first material dividing cylinder 7, and the piston rod of the second material dividing cylinder 7 are all retracted, so that the remaining hub bearing flanges 6 continue to move forward until the next hub bearing flange 6 reaches the discharge port of the feeding channel 3, and the above steps are repeated. The sensing needle of the unloading induction switch 11 of the unloading channel 4 is pushed by the hub bearing flange 6 grabbed by the short arm 24, and then the short arm 24 releases the hub bearing flange 6 and swings to the processing position.

[0036] In order to ensure that the short arm 24 does not fall off when releasing the wheel hub bearing flange 6, and the wheel hub bearing flange 6 can better move along the feed channel 4, a protective plate 12 is connected to the feed port of the feed channel 4, and the protective plate 12 is connected to the side of the feed channel 4 away from the panel 1, and the inclination angle of the limit plate is greater than the inclination angle of the feed channel 4.
