[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1As shown, this utility model provides an automated part size inspection device, including a support platform 1, a measuring platform 7 on the surface of the support platform 1, a support column 2 fixedly connected to the center of the support platform 1 near the measuring platform 7, an electric push plate 6 slidably connected to the bottom of the support column 2 near the surface of the measuring platform 7, the electric push plate 6 can push unqualified parts into the unloading hole 81, a sliding plate 3 slidably connected to the center of the support column 2, a digital micrometer 4 for measuring the outer diameter of bearing parts is provided on the upper part of the sliding plate 3, and an inspection camera 5 for inspecting the appearance of bearing parts is fixedly connected to the top of the support column 2. During use, the measuring platform 7 can clamp and transfer bearing parts. The digital micrometer 4 and the inspection camera 5 are connected to a controller to measure the external dimensions of the bearing parts and determine whether the appearance of the bearing parts meets the requirements. Unqualified bearing parts are pushed into the unloading hole 81 by the electric push plate 6. Through the linkage of the digital micrometer 4, the inspection camera 5, and the electric push plate 6, the sorting of bearing parts is more accurate.

[0024] like Figure 2As shown, the measuring platform 7 includes a cylinder 71. A cylinder slider 73 is fixedly connected to the output end of the cylinder 71. A sliding clamp 74 is slidably connected inside the cylinder slider 73. A sliding motor 76 is fixedly connected to the outer wall of one end of the cylinder slider 73. A threaded rod 82 is rotatably connected inside the cylinder slider 73. One end of the threaded rod 82 passes through the outside of the cylinder slider 73 and is fixedly connected to the output end of the sliding motor 76. Multiple sliding grooves 78 are opened inside the sliding clamp 74 on the same plane. Two sets of clamping rods 75 for clamping bearing parts are slidably connected inside the sliding grooves 78. A fixed platform 79 is provided at the front of the cylinder slider 73. A feeding conveyor belt 72 for conveying bearing parts is provided at the front of the fixed platform 79. A measuring top hole 80 is opened in the middle of the fixed platform 79 near the bottom of the detection camera 5. A discharge hole 81 that passes through the bottom is opened on the top side of the fixed platform 79 near the measuring top hole 80. A discharge conveyor belt 77 for discharging materials is provided at the rear of the fixed platform 79. The feeding conveyor belt 72 transports the bearing part to be measured to the clamping port of the clamping rod 75. The clamping rod 75 clamps the bearing part to be measured. The cylinder 71 retracts backward, driving the cylinder slider 73, the sliding clamping plate 74, and the clamping rod 75 to move backward. At this time, the sliding motor 76 drives the threaded rod 82, which is fixedly connected to the output end, to rotate. Through the action of the thread, the sliding clamping plate 74 moves to the right, moving the measuring bearing part clamped by the clamping rod 75 below the digital micrometer 4. Finally, the bearing part to be measured is placed in the groove of the measuring top rod 801. Inside 802, the measuring rod 801 lifts the bearing part so that its outer diameter contacts the measuring head of the digital micrometer 4. The measuring rod 801 rotates the bearing part one revolution, and the digital micrometer 4 measures the change in the outer diameter of the bearing part to determine whether the bearing part is qualified. The inspection camera 5 judges the appearance of the bearing part. If it is not qualified, the electric push plate 6 pushes the bearing part into the unloading hole 81. If the bearing part is qualified, another set of clamping rods 75 will clamp the bearing part and continue to move it. Finally, the bearing part is placed on the unloading conveyor belt 77 for unloading.

[0025] Conveyor belt 77 is an existing technology that allows for the cutting of measured parts using a traditional conveyor belt structure.

[0026] like Figure 5 As shown, a measuring rod 801 is installed inside the measuring top hole 80. The top of the measuring rod 801 is provided with a groove 802 for supporting the bearing parts and driving the bearing parts to rotate. The measuring rod 801 is an electric rod and a motor is fixedly connected to the bottom to rotate the bearing parts. The groove 802 is used to support the bearing parts to prevent the outer diameter of the bearing parts from not rotating. The groove 802 is provided with anti-slip rubber strips to increase the friction between the bearing parts and the groove 802, so that the bearing parts have a better rotation effect.

[0027] like Figure 3As shown, a rotary motor 721 is fixedly connected to the outer wall of the fixed frame of the feeding conveyor belt 72. The surface of the feeding conveyor belt 72 is provided with anti-slip protrusions 722. Two inclined guide plates 723, which can rotate around a rotation axis, are provided at the front of the feeding conveyor belt 72. The guide plates 723 can be fixed in a preset position during operation. The side of the two guide plates 723 that is close to each other has a passage opening that restricts the diameter of the bearing parts. A baffle 724 is provided at the tail of the feeding conveyor belt 72. The anti-slip protrusions 722 on the surface of the feeding conveyor belt 72 increase the friction between the bearing parts and the conveyor belt. The baffle 724 ensures that the clamping position of the parts conveyed by the conveyor belt 72 is consistent. The size of the passage opening that restricts the diameter of the bearing parts can be adjusted by the rotatable guide plates 723, changing the diameter of the bearing parts. It also limits the number of bearing parts that can pass through and maintains a certain distance between two adjacent bearing parts, preventing parts from clogging at the baffle 724 and affecting the clamping rod 75's ability to pick up parts.

[0028] like Figure 4 As shown, a chuck 754 for clamping bearing parts is fixedly connected to the top of the clamping rod 75. The surface of the chuck 754 for clamping the bearing parts is provided with anti-slip rubber strips 751. A pressure sensor 752 is installed inside the chuck 754. A telescopic rod 753 for adjusting the clamping gap is fixedly connected to the tail of the chuck 754. The telescopic rod 753 adjusts the clamping diameter between the two chucks by moving the chuck 754 left and right to accommodate bearing parts of different diameters. The anti-slip rubber strips 751 on the chuck surface prevent the parts from accidentally falling off due to insufficient friction after clamping. The pressure sensor 752 is used to reflect whether the external pressure that the bearing parts can withstand meets the requirements.

[0029] like Figure 2 As shown, the bottom surface of the bracket 802 is provided with an anti-slip rubber pad, which is used to increase the friction between the bearing parts and the bracket 802.

[0030] The working principle of this utility model is as follows: First, the bearing parts to be measured are placed on the feeding conveyor belt 72. The bearing parts are guided to the baffle 724 in sequence by the inclined guide plate 723. At this time, the clamping rod 75 clamps the bearing parts. The cylinder 71 retracts backward, driving the cylinder slider 73, the sliding clamp 74 and the clamping rod 75 to move backward. The sliding motor 76 drives the threaded rod 82 fixedly connected to the output end to rotate. Through the action of the thread, the sliding clamp 74 moves to the right. The clamping rod 75 places the bearing parts to be measured in the tray 802. The measuring rod 801 lifts the bearing parts so that the outer diameter of the bearing parts contacts the measuring head of the digital micrometer 4 and rotates one revolution to measure whether the outer diameter of the bearing parts meets the requirements. At the same time, the detection camera 5 detects the appearance of the bearing parts. After the clamping rod 75 clamps the parts that meet the requirements, it continues to move backward and is placed on the unloading conveyor belt 77 for unloading. For the parts that do not meet the requirements, the electric push plate 6 will push the parts into the unloading hole 81.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
