[0002] In the field of medical devices, after the tubular sheaths are manufactured, various external factors can cause defects to appear in the tubular sheaths. Therefore, an inspection device is needed to control whether the tubular sheaths are in a qualified state. Existing inspection devices require disassembling and installing another tubular sheath to be inspected after inspecting one workpiece before another inspection can be carried out, which is relatively inefficient. Therefore, there is an urgent need for a more efficient and easy-to-operate inspection device. Summary of the Invention
[0003] The purpose of this invention is to provide a casing defect detection device that can efficiently detect multiple tubular casings in a short time; and can ensure that the circumferential direction of the tubular casing can be completely detected, thus avoiding the situation where defects of the tubular casing are not detected.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a casing defect detection device, comprising: a large disc, a small disc, and a reducer arranged in parallel and vertically spaced on a platform, wherein the central through hole of the large disc is fitted onto the central shaft of the reducer and connected to the rotating shaft cylinder of the reducer, and the central shaft of the reducer is embedded in the central through hole of the large disc and connected to the central area of the small disc; The reducer mounted on the bracket is connected to a first motor at the end away from the large disc. A camera is provided on the side of the small disc opposite to the large disc. Several circular bolts embedded in the through holes of the large disc are provided at intervals around the edge of the large disc and around the periphery of the small disc. The front end of the circular bolt is located in front of the large disc for installing the tubular sleeve to be inspected. The rear end of the circular bolt is located behind the large disc and has an insertion hole. The hanger is provided with a slide plate and a carrier plate that cooperates with the slide plate. A second motor is installed on the surface of the slide plate opposite to the carrier plate. A cylinder is provided on the surface of the carrier plate opposite to the slide plate. The end of the piston rod of the cylinder is connected to the slide plate. A pin shaft that can be inserted into the insertion hole of a circular bolt is installed on the output shaft of the second motor.
[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the skateboard and the carrier plate that cooperates with the skateboard are set on the top of the hanger.
[0006] 2. In the above scheme, the second motor is located above the slide plate, and the cylinder is located below the carrier plate.
[0007] 3. In the above scheme, the end of the piston rod and the end of the slide plate are connected by a plate.
[0008] 4. In the above scheme, a limiting block is provided on the carrier plate between the sliding plate and the large disc.
[0009] 5. In the above scheme, the limiting block is embedded in the groove of the carrier plate.
[0010] 6. In the above scheme, a buffer is provided on the surface of the limiting block facing the carrier plate.
[0011] 7. In the above scheme, the slide plate is embedded in the side grooves located on both sides of the carrier plate.
[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to a sleeve defect detection device, comprising a large disc, a small disc, and a reducer arranged parallel to each other and vertically on a platform. The central through hole of the large disc is fitted onto the central shaft of the reducer and connected to the rotating cylinder of the reducer. The central shaft of the reducer is embedded in the central through hole of the large disc and connected to the central area of the small disc. A first motor is connected to the end of the reducer mounted on a bracket away from the large disc. A camera is mounted on the side of the small disc opposite to the large disc. Several circular pins embedded in the central through hole of the large disc are spaced apart on the edge area of the large disc and around the periphery of the small disc. The front end of the circular pin is located in front of the large disc for mounting the tubular sleeve to be inspected, and the rear end of the circular pin has an insertion hole. A sliding plate and a carrier plate that cooperate with the sliding plate are mounted on the bracket. A second motor is mounted on the surface of the sliding plate opposite to the carrier plate. A cylinder is installed on the surface opposite to the slide plate. The end of the piston rod of this cylinder is connected to the slide plate. A pin shaft that can be inserted into the insertion hole of a circular bolt is installed on the output shaft of the second motor. The large disc drives the tubular sleeve to be inspected to rotate circumferentially. At the same time, the camera inspects the tubular sleeves in turn. When the camera is inspecting one of the tubular sleeves, the large disc stops rotating. At this time, the operator can remove the other tubular sleeves that have been inspected and replace them with the tubular sleeve to be inspected. This allows the sleeve defect detection device to efficiently inspect multiple tubular sleeves in a short time. Furthermore, through the axial movement and rotation of the pin shaft, the circumference of the tubular sleeve can be completely detected by its own rotation when it is being inspected by the camera, thus avoiding the situation where the defects of the tubular sleeve are not detected.

Several circular bolts 8 are provided at intervals around the edge of the large disc 2 and around the periphery of the small disc 3. These circular bolts 8 are embedded in the through holes 202 in the large disc 2. The front end of the circular bolt 8 is located in front of the large disc 2 for installing the tubular sleeve 100 to be inspected. The rear end of the circular bolt 8 is located behind the large disc 2 and has an insertion hole 81. The hanger 5 is provided with a slide plate 9 and a carrier plate 10 that cooperates with the slide plate 9. A second motor 11 is installed on the surface of the slide plate 9 opposite to the carrier plate 10. A cylinder 12 is provided on the surface of the carrier plate 10 opposite to the slide plate 9. The end of the piston rod 121 of the cylinder 12 is connected to the slide plate 9. A pin shaft 13 that can be inserted into the insertion hole 81 in the circular bolt body 8 is installed on the output shaft of the second motor 11.
[0017] The aforementioned skateboard 9 and the carrier plate 10 that cooperate with the skateboard 9 are located on the top of the hanger 5.
[0018] The second motor 11 is located above the slide plate 9, and the cylinder 12 is located below the carrier plate 10.
[0019] The end of the piston rod 121 is connected to the end of the slide plate 9 by a plate 14.
[0020] The aforementioned slide plate 9 is embedded in the side grooves 102 located on both sides of the carrier plate 10.
[0021] Example 2: A casing defect detection device includes: a large disc 2, a small disc 3, and a reducer 4 arranged in parallel and vertically spaced on a platform 1. The central through hole 201 of the large disc 2 is fitted onto the central shaft 41 of the reducer 4 and connected to the rotating shaft cylinder 42 of the reducer 4. The central shaft 41 of the reducer 4 is embedded in the central through hole 201 of the large disc and connected to the central area of the small disc 3. The reducer 4 mounted on the bracket 5 is connected to a first motor 6 at the end away from the large disc 2. A camera 7 is provided on the side of the small disc 3 opposite to the large disc 2. Several circular bolts 8 are provided at intervals around the edge of the large disc 2 and around the periphery of the small disc 3. These circular bolts 8 are embedded in the through holes 202 in the large disc 2. The front end of the circular bolt 8 is located in front of the large disc 2 for installing the tubular sleeve 100 to be inspected. The rear end of the circular bolt 8 is located behind the large disc 2 and has an insertion hole 81. The hanger 5 is provided with a slide plate 9 and a carrier plate 10 that cooperates with the slide plate 9. A second motor 11 is installed on the surface of the slide plate 9 opposite to the carrier plate 10. A cylinder 12 is provided on the surface of the carrier plate 10 opposite to the slide plate 9. The end of the piston rod 121 of the cylinder 12 is connected to the slide plate 9. A pin shaft 13 that can be inserted into the insertion hole 81 in the circular bolt body 8 is installed on the output shaft of the second motor 11.
[0022] The end of the piston rod 121 is connected to the end of the slide plate 9 by a plate 14.
[0023] A limiting block 15 is provided on the carrier plate 10 between the slide plate 9 and the large disc 2.
[0024] By setting the limit block 15, it is prevented that after the pin shaft 13 is inserted into the circular bolt 8 under the drive of the cylinder, the pin shaft 8 will continue to move forward, causing the large disc 2 to tilt and thus causing damage to the large disc 2.
[0025] The aforementioned limiting block 15 is embedded in the groove 101 of the carrier plate 10.
[0026] A buffer 16 is provided on the surface of the limiting block 15 facing the carrier plate 10.
[0027] The buffer 16 slows down the limit block 15 and the slide plate 9 in advance when they are about to make contact, so as to avoid damage to the carrier plate 10, the slide plate 9 and related components caused by high-speed contact.
[0028] The aforementioned slide plate 9 is embedded in the side grooves 102 located on both sides of the carrier plate 10.
[0029] The working principle of this patent is as follows: First, the tubular sleeve 100 to be inspected is fitted onto the circular plug 8. Then, the first motor 6 drives the large disc 2 to rotate through the reducer 4. When the tubular sleeve 100 to be inspected on the large disc 2 is positioned directly above the camera 7, the large disc 2 stops rotating. At this time, driven by the cylinder 12, the pin shaft 13 connected to the second motor 11 on the slide plate 9 is inserted into the insertion hole 81 of the circular plug 8. At this time, the second motor 11 works, and the tubular sleeve 100 to be inspected fitted onto the circular plug 8 rotates. At this time, the camera can detect whether there are any defects on the circumferential surface of the tubular sleeve 100 to be inspected. While the camera 7 is working, if other circular plugs 8 are installed with tubular sleeves that have been inspected, the operator can remove the tubular sleeve and install a new tubular sleeve 100 to be inspected. After the camera 7 has finished inspecting the current tubular sleeve, the pin shaft 13 disengages from the circular plug 8, and under the rotation of the large disc 2, another tubular sleeve 100 to be inspected moves to the top of the camera 7, and then the cycle continues.
[0030] When using the aforementioned sleeve defect detection device, a large disc drives the tubular sleeve to be inspected to rotate circumferentially. Simultaneously, a camera sequentially inspects the tubular sleeves. When the camera is inspecting one tubular sleeve, the large disc stops rotating. At this point, the operator can remove the other inspected tubular sleeves and replace them with the tubular sleeve to be inspected. This allows the sleeve defect detection device to efficiently inspect multiple tubular sleeves in a short time. Furthermore, through the axial movement and rotation of the insert shaft, the circumferential direction of the tubular sleeve can be completely detected by its own rotation when being inspected by the camera, avoiding the situation where defects in the tubular sleeve are not detected.
[0031] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
