In actual operation, when mechanical equipment is used to inspect annular workpieces, it is difficult to align the workpiece with the center of the inspection equipment, which will cause the equipment to be subjected to additional pressure or impact during measurement. In the long run, it will damage the measuring mechanism of the equipment or affect the stability of the equipment. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art that manual detection errors are large and mechanical equipment detection cannot quickly align workpieces, and proposes a ring-shaped workpiece inner diameter detection device.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, the utility model provides a ring-shaped workpiece inner diameter detection device, including a mounting frame 1 and a lifting plate 3, the top of the mounting frame 1 is symmetrically fixedly connected with a cylinder 2, the bottom end of the cylinder 2 passes through the mounting frame 1, and the bottom of the cylinder 2 is fixedly connected to the top of the lifting plate 3, and a detection component 6 is installed at the bottom of the lifting plate 3;

[0026] The detection component 6 includes a support frame 61 and a fixed tube 62. Four guide holes 611 are opened on the surface of the support frame 61. A threaded rod 67 is rotatably connected to the inner side of the fixed tube 62. A movable plate 642 is threadedly connected to the outer surface of the threaded rod 67. A lifting sleeve 64 is fixedly connected to the top of the movable plate 642. A guide block 66 is slidably connected to the inner side of the guide hole 611. A connecting plate 68 is fixedly connected to the bottom of the guide block 66. Linkage rods 65 are rotatably connected to both sides of the top and bottom of the connecting plate 68, and a detection plate 63 is fixedly connected to one side of the connecting plate 68.

[0027] The specific settings and functions of this embodiment are described in detail below. During the detection process, when the fixed tube 62 rotates, the movable plate 642 will be driven to start moving. At the same time, the movable plate 642 will also drive the lifting sleeve 64 to move together, so that the lifting sleeve 64 slides on the surface of the fixed tube 62. As the lifting sleeve 64 moves up and down, it will use the convex plate 641 to drive multiple linkage rods 65 to move together. Under the guiding and limiting action of the guide block 66, the connecting plate 68 will move linearly, thereby driving the detection plate 63 to slide. In this way, when the connecting plate 68 moves, the top guide block 66 will ensure linear movement under the limitation of the guide hole 611, so that the detection plate 63 also maintains linear movement when it moves.

[0028] Finally, when the lifting sleeve 64 is lifted, the four detection plates 63 will be simultaneously deployed under the drive of the multiple linkage rods 65. At this time, the four detection plates 63 will contact the inner wall of the workpiece, and then the inner diameter of the workpiece can be measured and detected. According to the moving distance of the detection plate 63, combined with the data displayed on the display screen on one side of the display 7, the inner diameter size of the workpiece can be quickly obtained, thereby judging whether the workpiece meets the standard.

[0029] Embodiment 2

[0030] like Figure 1-3 As shown, a driving motor 5 is installed on one side of the top of the lifting plate 3, and the output end of the driving motor 5 is fixedly connected to the belt transmission assembly 4. A display 7 is fixedly connected to the center of the top of the lifting plate 3, and a fixed tube 62 and a support frame 61 are fixedly connected. The top of the fixed tube 62 is rotatably connected to the belt transmission assembly 4, and the fixed tube 62 is fixedly connected to the lifting plate 3. The top of the threaded rod 67 passes through the lifting plate 3 and the display 7 in sequence, and the top of the threaded rod 67 is fixedly connected to the driven wheel of the belt transmission assembly 4. Four convex plates 641 are fixedly connected to the outer wall of the lifting sleeve 64, and the convex plates 641 are rotatably connected to two linkage rods 65. The lifting sleeve 64 is slidably connected to the fixed tube 62.

[0031] The effect achieved by the entire embodiment is that when performing inspection, we use the mounting frame 1 to firmly install the inspection system. The annular workpiece to be inspected is accurately conveyed to the bottom of the inspection assembly 6 by the conveyor belt. Subsequently, through the control of the cylinder 2, the lifting plate 3 performs a lifting movement, driving the inspection assembly 6 to move downward until it completely enters the inside of the workpiece. During the inspection process, when the workpiece moves to the predetermined position, the four inspection plates 63 will start to move at the same time. If the four inspection plates 63 fail to contact the inner wall of the workpiece at the same time, the inspection plates 63 that continue to move will slightly push the workpiece to ensure that the four inspection plates 63 can contact the workpiece at the same time. This design makes it unnecessary to deliberately control the center of the workpiece to completely coincide with the center of the fixed tube 62 during the inspection process.

[0032] The start of the driving motor 5 drives the belt drive assembly 4 to rotate, thereby driving the fixed tube 62 to rotate. This rotational motion effectively controls the position of the detection plate 63, so that it can perform all-round and accurate detection inside the workpiece.

[0033] The design of the mounting frame 1 is highly flexible and can be connected to various mobile devices. By utilizing the support function of the detection plate 63, we can automatically transfer the workpieces that do not meet the standards, thereby realizing the automation and efficiency of workpiece detection.

[0034] The use method and working principle of the device: When testing annular workpieces, first, the detection system is firmly mounted on the workbench using the mounting frame 1, ensuring the stability and reliability of the entire detection process. The annular workpiece to be tested is conveyed to the bottom of the detection assembly 6 by the conveyor belt.

[0035] Next, the lifting plate 3 is controlled by the cylinder 2 to move upward and downward. When the lifting plate 3 descends, it drives the detection assembly 6 to move downward until the detection plate 63 is completely moved to the inside of the workpiece. This process is precise and rapid, ensuring that the detection assembly 6 can be accurately positioned inside the workpiece, ready for subsequent detection work.

[0036] During the detection process, when the fixed tube 62 rotates, it will drive the moving plate 642 to start moving. At the same time, the moving plate 642 will also drive the lifting sleeve 64 to move together, so that the lifting sleeve 64 slides on the surface of the fixed tube 62. As the lifting sleeve 64 moves up and down, it will use the convex plate 641 to drive multiple linkage rods 65 to move together. Under the guiding and limiting action of the guide block 66, the connecting plate 68 will move linearly, thereby driving the detection plate 63 to slide. In this way, when the connecting plate 68 moves, the top guide block 66 will ensure linear movement under the limitation of the guide hole 611, so that the detection plate 63 also maintains linear movement when it moves.

[0037] Finally, when the lifting sleeve 64 is lifted, the four detection plates 63 will be simultaneously deployed under the drive of the multiple linkage rods 65. At this time, the four detection plates 63 will contact the inner wall of the workpiece, and then the inner diameter of the workpiece can be measured and detected. According to the moving distance of the detection plate 63, combined with the data displayed on the display screen on one side of the display 7, the inner diameter size of the workpiece can be quickly obtained, thereby judging whether the workpiece meets the standard.

[0038] When one or more of the detection plates 63 first contact the workpiece, it will slightly push the workpiece, allowing the other detection plates 63 to gradually contact the workpiece. This process is completed automatically without human intervention, thus ensuring that the four detection plates 63 can contact the workpiece at the same time, improving the accuracy and reliability of detection.

[0039] In summary, this ring-shaped workpiece detection system realizes the automatic detection and processing of ring-shaped workpieces through its efficient and precise operation mechanism. It not only improves the detection efficiency and accuracy, reduces labor costs, but also provides strong technical support for the automation upgrade of the production line.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
