[0002] A steel bar sleeve, also known as a steel bar joint, is a connecting piece used to connect steel bars and having an internal thread corresponding to the thread of the wire head. The simple construction process is as follows: the end of the steel bar is processed into a straight thread by a rolling process, and two steel bars are connected to each other by a corresponding connecting sleeve. After the sleeve is manufactured, a detection device is required to detect the surface defects.

[0003] The prior art (publication number: CN 215639278 U) discloses a part size laser detection device, including a detection fixture and a detection mechanism. The detection mechanism is located above the detection fixture, and the detection mechanism faces the detection fixture. The detection fixture includes a detection plate, and at least three limiting grooves are symmetrically arranged in the detection plate. The horizontal cross-section of the limiting groove is a combination of a right trapezoidal part and a rectangular part, and the included angle between the inclined waist and the bottom edge of the right trapezoidal part is 60-120°.

[0004] Although the above patent can install multiple products each time through the setting of the fixture, and cooperate the detection fixture with the transmission mechanism and the detection mechanism to realize the rapid installation and batch detection of non-standard parts, which can meet the detection requirements of the key dimensions of non-standard parts and greatly improve the detection efficiency and detection accuracy, there are the following disadvantages: it takes a certain amount of time to detect parts, and other operation steps cannot be carried out during the detection. It is necessary to wait for the parts to be detected before the steps of disassembling and installing the parts can be carried out, and continuous detection cannot be carried out. A large amount of time is wasted during the waiting process, which affects the work efficiency. Further improvement is needed. For this reason, we propose a sleeve part size defect detection device. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a sleeve part size defect detection device, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A vision camera 11 is installed at the moving end of the linear module 10. The linear module 10 is used to drive the vision camera 11 to move left and right.

[0025] In order to continuously detect the sleeve parts, reduce the waste of time, and improve the detection productivity, by setting the rotating component 13 and the rotating plate 3 to cooperate with each other, the parts can be alternately detected, and the working efficiency can be improved. The specific structure is as follows: The rotating component 13 includes a U-shaped frame 131. The U-shaped frame 131 is installed at the lower end of the bottom plate 1. A motor 132 is installed at the lower end of the U-shaped frame 131. The output end of the motor 132 movably penetrates the upper wall of the U-shaped frame 131 and is fixedly connected to a first gear 133. The first gear 133 is meshed with a second gear 134. The number of teeth of the first gear 133 is less than that of the second gear 134 to improve the transmission accuracy and torque. A connecting shaft 135 is fixedly sleeved inside the second gear 134. The upper end of the connecting shaft 135 movably penetrates the upper end of the bottom plate 1 and is fixedly connected to the lower end of the rotating plate 3.

[0026] When a sleeve part is detected to have a defect, the defective part can be automatically discharged from the placement groove 6 through the material pushing component 7, without the need for workers to manually pick up the defective parts. Workers only need to pick up the qualified parts, further reducing the labor intensity of the workers and improving work efficiency. The specific structure is as follows: The material pushing component 7 includes a support frame 71, which is installed on the bottom plate 1. A number of second cylinders 72 arranged in a linear array are installed at the rear end of the support frame 71. The output ends of the number of second cylinders 72 all movably penetrate through the rear end of the support frame 71 and are fixedly connected to a push plate 73. The number of push plates 73 are respectively located at the rear sides of a number of the rear placement grooves 6.

[0027] A first cylinder 12 is arranged at the rear side of the vertical plate 8. The first cylinder 12 is installed on the bottom plate 1. The output end of the first cylinder 12 is fixedly connected to a positioning plate 9. The front end of the positioning plate 9 movably penetrates to the front end of the vertical plate 8. The positioning plate 9 is located at the rear side of the rear placement block 5. The positioning plate 9 has the same structure as the placement block 5. The positioning plate 9 is used to position the part so that the part is directly below the vision camera 11, facilitating subsequent shooting.

[0028] The vision camera 11 is located above the rear placement groove 6. The vision camera 11 is used to transmit the captured image to a computer, and the image is processed and analyzed through an algorithm to finally obtain the detection result.

[0029] A size defect detection device for sleeve parts proposed by the present utility model. When in use, the sleeve part to be detected is placed in the placement groove 6 on the front side. The motor 132 is controlled to drive the first gear 133 to rotate, the first gear 133 drives the second gear 134 to rotate, and the second gear 134 drives the rotating plate 3 to rotate half a circle through the connecting shaft 135, so that the part rotates to the lower part of the vision camera 11. The output end of the first cylinder 12 is controlled to extend to drive the positioning plate 9 to move forward to position the sleeve part. After positioning, the output end of the first cylinder 12 is controlled to drive the positioning plate 9 to reset. Then, the linear module 10 is controlled to drive the vision camera 11 to move to take a picture of the part, convert the captured target into an image signal, and transmit it to a dedicated image processing system. According to information such as pixel distribution, brightness, and color, it is converted into a digital signal. The image system performs various operations on these signals to extract the features of the target, so as to judge whether there are defects in the part. When the vision camera 11 detects that the part is unqualified, the output end of the second cylinder 72 at the corresponding position is controlled to extend to drive the push plate 73 to move forward. The push plate 73 pushes the sleeve part away from the placement groove 6 and places it into the waste box placed below the discharge chute 2, and then it falls into the waste box through the discharge chute 2. During the detection, other parts to be detected are placed in the placement groove 6 on the front side. After the detection is completed, the rotating component 13 is controlled to drive the rotating plate 3 to rotate half a circle again, so that the detected part and the undetected part are swapped, and the sleeve parts can be continuously detected. While detecting, the detected parts are removed and new parts are installed.
