Description

Technical Field

[0001] The utility model relates to the technical field of appearance detection of small-module bevel gears, in particular to an automatic detection device for appearance defects of small-module bevel gears. Background Art

[0002] A small-module bevel gear is a gear design with a relatively small module (a measure of the gear's size). In mechanical design, small-module gears are often used in precision transmission systems, such as in watches, cameras, precision instruments, and certain automotive components. Due to their small size, they are well-suited for applications requiring space efficiency and precision transmission. The design and manufacture of small-module gears require a high degree of precision, as the smaller the gear's module, the finer the tooth profile, and the higher the precision required in gear machining and assembly. This type of gear often utilizes specialized machining techniques, such as grinding or ultra-precision machining, to ensure the required smoothness and accuracy. A bevel gear is a gear with a conical geometry that transmits rotational motion and force from one shaft to another and can provide a large torque ratio between the shafts. Bevel gears are often used in pairs to achieve precise speed and torque transmission.

[0003] When inspecting the appearance of small-module bevel gears, since the sizes of small-module bevel gears are different, it is necessary to adjust the distance between the industrial camera and the small-module bevel gear during inspection to ensure the clarity of the image of the small-module bevel gear taken by the industrial camera. Based on this, an automatic detection device for the appearance defects of small-module bevel gears is proposed. Utility Model Content

[0022] Example:

[0023] Reference Figure 1-Figure 4 , an automatic detection device for the appearance defects of small-module bevel gears, including a detection platform 1 and an industrial camera 13 arranged on the detection platform 1, and also including a motor 4 installed at the bottom of the detection platform 1, the output end of the motor 4 is fixedly connected to a three-jaw chuck 5, and the outside of the three-jaw chuck 5 is fixedly connected to a gear ring 6, wherein the top of the detection platform 1 is rotatably connected to a reciprocating screw 8, the outer wall of the reciprocating screw 8 is fixedly connected to a rotating gear 7, the rotating gear 7 is meshed with the gear ring 6, and the lifting block 10 is connected to the reciprocating screw 8 by a thread, a high-pressure nozzle 3 is installed on the top of the detection platform 1, and a control panel 2 is installed on the top of the detection platform 1, the control panel 2 is used to control the motor 4, the three-jaw chuck 5 and the industrial camera 13. It should be noted that when the appearance of the small-module bevel gear is photographed using the industrial camera 13, the photographed picture is sent to the control panel 2, and the image processing module in the control panel 2 processes the picture and analyzes whether the photographed picture data of the small-module bevel gear meets the standard quality picture data in the database, thereby realizing the appearance quality inspection of the small-module bevel gear.

[0024] When in use, first place the small module bevel gear on the three-jaw chuck 5, then start the three-jaw chuck 5 to clamp the small module bevel gear, and make the high-pressure nozzle 3 spray high-pressure gas to act on the small module bevel gear to clean the outer surface of the small module bevel gear. At the same time, start the motor 4 and the industrial camera 13 so that the motor 4 drives the three-jaw chuck 5 to rotate, and then the small module bevel gear rotates, so that the industrial camera 13 takes a full-scale picture of the small module bevel gear, and sends the taken picture to the control panel 2, which processes the taken picture to determine whether the small module bevel gear has defects.

[0025] Reference Figure 1-Figure 4 , also includes: a fixed frame 9 fixedly connected to the top of the testing platform 1, a connecting frame 11 is slidably connected to the fixed frame 9, the end of the connecting frame 11 is fixedly connected to the lifting block 10, the inside of the connecting frame 11 is slidably connected to the adjusting frame 12, one side of the lifting block 10 is rotatably connected to a threaded rod 14, wherein the threaded rod 14 is rotatably connected to the connecting frame 11, the threaded rod 14 is connected to the adjusting frame 12 by a thread, the adjusting frame 12 passes through the lifting block 10 and is slidably connected to the lifting block 10, a slide groove 15 is opened on the fixed frame 9, the threaded rod 14 can slide in the slide groove 15, the industrial camera 13 is fixedly connected to the end of the adjusting frame 12, and the industrial camera 13 is installed on the side of the lifting block 10 away from the connecting frame 11.

[0026] After the small-module bevel gear is installed above the three-jaw chuck 5, it is necessary to adjust the distance between the industrial camera 13 and the small-module bevel gear according to the size of the small-module bevel gear to ensure the clarity of the image shooting. At this time, the threaded rod 14 is rotated to make the adjustment frame 12 slide in the connecting frame 11, thereby adjusting the distance between the industrial camera 13 and the small-module bevel gear until the industrial camera 13 can clearly capture the appearance image of the small-module bevel gear. The motor 4 can then be started for inspection. During the inspection process, the rotation of the three-jaw chuck 5 will drive the rotating gear 7 to rotate through the gear ring 6, thereby rotating the reciprocating screw 8. The rotation of the reciprocating screw 8 will cause the lifting block 10 to slide up and down, thereby driving the industrial camera 13 to slide up and down, so that the industrial camera 13 can take a full-scale picture of the appearance of the small-module bevel gear.

[0027] When automatically inspecting the appearance defects of small-module bevel gears of different sizes, the rotation of the threaded rod 14 will cause the adjustment frame 12 to push or pull the industrial camera 13 to move, thereby adjusting the distance between the industrial camera 13 and the small-module bevel gear to ensure the clarity of the pictures taken by the industrial camera 13, thereby improving the accuracy of the appearance inspection of the small-module bevel gear; and expanding the range of the industrial camera 13 for photographing the appearance of the small-module bevel gear, thereby further improving the accuracy of the appearance inspection of the small-module bevel gear.
