[0002] The full-automatic hub dimension measurement program is a highly automated industrial inspection solution, aiming to accurately and quickly measure various dimension parameters of automobile hubs to ensure that the product quality meets the standards. Such programs usually integrate advanced machine vision technology, precision measuring instruments and intelligent algorithms, and can realize the all-round and non-contact measurement of hubs.
[0003] For accurate measurement, during the detection by the detection equipment, it is usually necessary to perform laser marking, and after manual re-inspection and confirmation, robot loading and unloading is carried out. Usually, the vehicle hub is conveyed to the re-inspection platform through the conveying equipment. If the conveyor belt is accidentally collided during the transportation process, the vehicle hub on the conveyor belt may shift, resulting in the vehicle hub being transported to the re-inspection platform may shift, resulting in deviation when the robotic arm and the fixture grasp the vehicle hub. Moreover, the weight of the vehicle hub is usually large, and it is not convenient for manual adjustment, which may affect the subsequent detection. Therefore, a full-automatic hub dimension measurement device is proposed for the above problems. Content of the Utility Model

A distance measuring instrument is installed inside the protective housing. The top of the feeding conveyor is detachably connected with a mounting plate through bolts. An electric telescopic rod is installed on the top of the mounting plate. The output end of the electric telescopic rod is fixedly connected with symmetrically arranged mounting strips. Bearings with relative rotation of the inner ring and the outer ring are arranged inside the mounting strips. The inner ring of the bearing is fixedly connected with a connecting shaft rod. A roller is fixedly connected to the outside of the connecting shaft rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] In the present utility model, through the structure composed of a distance measuring instrument, an electric telescopic rod, a mounting strip, a bearing, a connecting shaft rod and a roller, etc., when measuring the size of the wheel hub, the wheel hub is placed on the feeding conveyor, and the feeding conveyor conveys the wheel hub. When the wheel hub is conveyed to the position of the distance measuring instrument, the distance measuring instrument will emit a laser detection ray to measure the distance to the wheel hub. The symmetrically arranged distance measuring instruments will display the obtained information on the numerical control display screen through the electric control cabinet. If the obtained data deviates too much, the electric telescopic rod on the side of the wheel hub that is closer can be started through the numerical control display screen.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.
[0021] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation.

Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.
[0024] In addition, it should be noted that the use of words such as "first", "second", etc. to limit the components is only for the convenience of distinguishing the corresponding components. Without separate statement, the above words have no special meaning. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.
[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0026] A full-automatic hub size measuring device includes a feeding conveyor 1, a laser marking re-inspection table 2, a gripping robot 3, a coordinate measuring device 4, a non-conforming tray 5, a discharging conveyor 6, an electric control cabinet 7, and a numerical control display screen 8. A mounting block 9 is detachably connected to the top of the feeding conveyor 1 by bolts. A protective housing 10 is fixedly connected between a group of mounting blocks 9. A distance measuring instrument 11 is installed inside the protective housing 10. A mounting plate 12 is detachably connected to the top of the feeding conveyor 1 by bolts. An electric telescopic rod 13 is installed on the top of the mounting plate 12. The output end of the electric telescopic rod 13 is fixedly connected with symmetrically arranged mounting bars 14. Inside the mounting bars 14, there is a bearing 15 with a relatively rotating inner ring and outer ring. The inner ring of the bearing 15 is fixedly connected with a connecting shaft rod 16. A roller 17 is fixedly connected to the outer side of the connecting shaft rod 16.
[0027] The distance measuring instruments 11 are symmetrically arranged and are electrically connected to the electric control cabinet 7 and the numerical control display screen 8. This setting enables the distance measuring instruments 11 to display the measured data on the numerical control display screen 8 through the electric control cabinet 7. The outer ring of the bearing 15 is fixedly connected to the mounting bar 14, and the bearings 15 are evenly arranged. This setting enables the installation of the bearings 15, allowing the roller 17 to rotate relatively under the action of the connecting shaft rod 16 and the bearing 15, thus not affecting the movement of the hub. The electric telescopic rods 13 are symmetrically arranged and are electrically connected to the electric control cabinet 7 and the numerical control display screen 8. This setting enables the projection to push the mounting bar 14 to move through the electric telescopic rods 13. The mounting bar 14 drives the bearing 15, the connecting shaft rod 16, and the roller 17 to move, applying the roller 17 to the hub and pushing the hub to move relatively on the feeding conveyor 1. The telescopic length of the electric telescopic rods 13 can be adjusted through the cooperation of the electric control cabinet 7 and the numerical control display screen 8. The laser marking re-inspection table 2 is installed on one side of the feeding conveyor 1. The electric control cabinet 7 is installed on the side of the laser marking re-inspection table 2 away from the feeding conveyor 1. The numerical control display screen 8 is installed on one side of the electric control cabinet 7 and is electrically connected to the electric control cabinet 7. The gripping robot 3 is installed on one side of the laser marking re-inspection table 2. The coordinate measuring devices 4 are symmetrically arranged and installed on both sides of the gripping robot 3. The non-conforming tray 5 is arranged on the side of the gripping robot 3 away from the laser marking re-inspection table 2. The discharging conveyor 6 is installed on one side of the non-conforming tray 5. This setting enables the detection of the size of the hub through the feeding conveyor 1, the laser marking re-inspection table 2, the gripping robot 3, the coordinate measuring device 4, the non-conforming tray 5, the discharging conveyor 6, the electric control cabinet 7, and the numerical control display screen 8.
[0028] Workflow: All the electrical appliances in this utility model are provided with an external power supply or a built-in battery. When measuring the size of the wheel hub, place the wheel hub on the feeding conveyor 1. The feeding conveyor 1 conveys the wheel hub. When the wheel hub is conveyed to the position of the distance measuring instrument 11, the distance measuring instrument 11 emits a detection ray to measure the distance to the wheel hub. The distance measuring instrument 11 is installed through the protective housing 10. The protective housing 10 is installed on the top of the feeding conveyor 1 through the mounting block 9. The symmetrically arranged distance measuring instruments 11 will display the obtained information on the numerical control display screen 8 through the electrical control cabinet 7. If the obtained data has a large deviation, the electric telescopic rod 13 on the side where the wheel hub is closer will be started through the numerical control display screen 8. The electric telescopic rod 13 is installed on the top of the feeding conveyor 1 through the mounting plate 12. The length of the extension of the electric telescopic rod 13 can be judged according to the obtained data. The electric telescopic rod 13 drives the mounting strip 14 to move. The mounting strip 14 drives the bearing 15, the connecting shaft rod 16 and the roller 17 to move. The roller 17 acts on the wheel hub to push the wheel hub to move relatively on the feeding conveyor 1. When the electric telescopic rod 13 extends to the set length, it will stop starting. The roller 17 can rotate relatively under the action of the connecting shaft rod 16 and the bearing 15, so it will not affect the movement of the wheel hub. The feeding conveyor 1 conveys the wheel hub to the laser marking re-inspection table 2. The position of the air inlet hole is visually recognized. The device on the laser marking re-inspection table 2 performs laser marking on the wheel hub. After manual re-inspection and confirmation, the grabbing robot 3 grabs the wheel hub on the laser marking re-inspection table 2 and places the wheel hub on the three-coordinate measuring device 4. The three-coordinate measuring device 4 automatically scans the wheel hub to obtain its size. The data obtained can be observed from the numerical control display screen 8. The qualified wheel hubs will be placed in the next processing procedure for the next round of processing. The unqualified wheel hubs will be taken by the grabbing robot 3 and placed on the unqualified tray 5, and will be conveyed to the next inspection process through the discharging conveyor 6.
