[0002] The epoxy resin ring is a ring-shaped structure formed by epoxy resin. It is a polymer material with good performance, and has excellent adhesion, corrosion resistance, insulation and mechanical strength. When processing the epoxy resin ring, it is necessary to use a turning and cutting machine for turning. Since high-precision turning is required on the epoxy resin ring, workers are required to use tools to manually mark the epoxy resin ring before turning to facilitate subsequent precise turning. After marking, the epoxy resin ring is placed on the turning and cutting machine for cutting.

[0003] The current epoxy resin ring turning and cutting machine, when processing the epoxy resin ring, has workers use tools to mark the epoxy resin ring, and then use the turning and cutting machine to cut it, resulting in relatively low efficiency in processing the epoxy resin ring. At the same time, during the manual marking process, it is necessary to use tools to measure the center of the epoxy resin, and then expand the center to mark, which further reduces the processing efficiency of the epoxy resin ring. Summary of the invention

[0031] The marking assembly includes a first electric telescopic rod 8 fixedly connected to the lower end of the threaded cylinder 73 , and a paintbrush 81 fixedly connected to the lower end of the first electric telescopic rod 8 .

When the present invention is in use, when the epoxy resin ring is processed by the turning and cutting integrated machine, the spacing between the two groups of first electric telescopic rods 8 and the brush 81 is first adjusted according to the size of the epoxy resin ring to be marked, and the motor 71 is started under the support of the second support plate 7 during the adjustment. After the motor 71 is started, the output shaft drives the double-headed threaded rod 72 to rotate. After the double-headed threaded rod 72 rotates, it engages with the thread of the threaded cylinder 73, so that the threaded cylinder 73 drives the two groups of first electric telescopic rods 8 and the brush 81 to move with the assistance of the limit block 74. When the two groups of first electric telescopic rods 8 and the brush 81 move to the appropriate position, the motor 71 can be turned off at this time, and then the epoxy resin ring to be processed is placed on the placement table 21, and then the air pump 3 is started under the support of the second shell 32. 4, after the air pump 34 is started, the air inside the upper end of the second shell 32 is pumped out. As the air inside the upper end of the second shell 32 is pumped out, the air pressure inside the second shell 32 changes, thereby pulling the sealing plate 42 and the sealing ring 43 upward. After the sealing plate 42 and the sealing ring 43 move upward, they synchronously pull the pull plate 41 and the pull rod 6 to move. After the pull plate 41 is pulled, it drives the first push plate 4 to move. As the first push plate 4 moves, the first push plate 4 pushes the second push plate 52 to move. After the second push plate 52 moves, it pushes the movable telescopic rod 5 and the clamping plate 53 to move the compression spring 51. When the clamping plate 53 fits the epoxy resin ring, it is squeezed and clamped. As the first push plate 4 continues to move upward, when the epoxy resin ring is clamped and restricted by the circumference of the clamping plate 53, the movable telescopic rod 5 is compressed due to continuous squeezing. The pull rod 6 is pulled and the transmission rod 61 is driven to move. After the transmission rod 61 moves, it rotates and pushes the push rod 62 to move. After the push rod 62 moves, it pushes the second support plate 7 synchronously, so that the second support plate 7 pushes the two groups of first electric telescopic rods 8 and the paintbrush 81 to move through the double-headed threaded rod 72, so that the paintbrush 81 draws lines on the epoxy resin ring. When the first push plate 4 rises and reaches the top of the first shell 3, the paintbrush 81 finishes drawing lines on the epoxy resin ring. Then, the second electric telescopic rod 91 is started under the support of the third support plate 9. After the second electric telescopic rod 91 is started, the output shaft pushes the fixed block 92 to drive the first shell 3 and the first support plate 31 to move, so that the first shell 3 drives the epoxy resin ring to move through the clamping of the splint 53 on the epoxy resin. When the epoxy resin ring moves to the cutting area, the air pump 34 is started to allow the air pump 34 to inject external air into the second shell 32, so that the air pressure in the second shell 32 changes again, and then pushes the sealing plate 42 and the sealing ring 43 downward. As the sealing plate 42 and the sealing ring 43 move downward, the pull rod 6 pushes the transmission rod 61 and the push rod 62 back to their positions, and the push rod 62 drives the first electric telescopic rod 8 and the paintbrush 81 to return through the second support plate 7. At the same time, the sealing plate 42 also pushes the pull plate 41 and the first push plate 4 downward. As the first push plate 4 returns, the elastic potential energy of the spring 51 is used to push the movable telescopic rod 5, the second push plate 52 and the splint 53 to return. After the splint 53 returns, the clamped epoxy resin ring falls to the cutting area for subsequent processing.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
