With the rapid development of industrial technology, the types and specifications of flange joints are increasing day by day, and the installation difficulty is gradually increasing. Therefore, how to improve the installation quality and efficiency of flange joints and cultivate professional installation technicians has become an urgent problem to be solved in the industrial field.

[0004] However, when using the traditional flange joint installation teaching device, some structures cannot be replaced, resulting in high usage loss of the equipment, short service life of the traditional teaching equipment, and single teaching type. Continuously replacing the teaching device is costly. Therefore, a multifunctional teaching device that takes into account the installation of flange joints and on-site machining is proposed to solve the above problems. Content of the Utility Model

[0023] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a multifunctional teaching device that takes into account the installation of flange joints and on-site machining, including a pipe body 2, which plays a role in supporting the movement of the internal structure.

A flange plate 3 is abutted and connected to the top of the pipe body 2, and the flange plate 3 provides a simulation of the training scenario for flange end face machining. Disassembly blocks 5 are fixedly connected to both the front and rear sides of the bottom of the flange plate 3. The function of the disassembly blocks 5 is to provide support for the disassembly and installation structure. Two uniformly distributed sliding rods 24 are slidably connected inside the disassembly blocks 5. The two sliding rods 24 can stabilize the sliding of the disassembly strip 8. One end of each of the two sliding rods 24 is fixedly connected with a limiting plate 7, and the two limiting plates 7 can prevent the two sliding rods 24 from sliding excessively. The other ends of the two sliding rods 24 are fixedly connected with a disassembly strip 8, and the disassembly strip 8 can abut and lock the installation block 6 to prevent the disassembly block 5 from moving. A round rod 10 is slidably connected to the middle part inside the disassembly block 5. The two round rods 10 can respectively pull the two disassembly strips 8 to move. One end of each of the two round rods 10 is fixedly connected to the middle part of the two disassembly strips 8. Springs 11 are sleeved on the outer circumferences of the two round rods 10. The two springs 11 can rebound and respectively push the two disassembly strips 8 back to their positions. Limiting blocks 9 are fixedly connected to both ends of the two disassembly strips 8. The multiple limiting blocks 9 can prevent the two disassembly strips 8 from drooping when they extend to the longest. Limiting grooves are opened inside each of the two disassembly blocks 5, and the multiple limiting blocks 9 respectively slide inside the two limiting grooves. The other end of the round rod 10 is rotatably connected with a handle 12, and the two handles 12 can pull the round rod 10 to move. The two handles 12 are both made of rubber, and the rubber can prevent slipping. A splicing component is arranged inside the pipe body 2, and the splicing component is used for disassembling and assembling the base 1 for convenient transportation. Multiple uniformly distributed fixing screws 1-20 are fixedly connected to the bottom of the base 1, and the fixing screws 1-20 are used for fixing the handle 1-22. Among them, two fixing screws 1-20 are rotatably connected to the opposite sides of a handle 1-22, and the two handles 1-22 are used for moving the base 1. A top cover 4 is abutted against the top of the flange plate 3. Multiple uniformly distributed fixing screws 2-21 are fixedly connected to the bottom of the flange plate 3.

Among them, two fixing screws 2-21 are rotatably connected to the opposite sides of a handle 2-23, and the two handles 2-23 are used for moving the flange plate 3.

[0024] Refer to Figure 1 and Figure 3, the splicing component includes a turntable 13. The function of the turntable 13 is to facilitate the staff to rotate the bidirectional threaded rod 14. The turntable 13 is rotatably connected to the front side of the pipe body 2. A bidirectional threaded rod 14 is fixedly connected to the rear side of the turntable 13. The bidirectional threaded rod 14 is rotatably connected inside the pipe body 2. Two moving blocks 15 are threadedly connected to the outer periphery of the bidirectional threaded rod 14. The function of the moving blocks 15 is to drive the crank arms 16 to move. Both ends of the two moving blocks 15 are rotatably connected to the crank arms 16. The function of the crank arms 16 is to drive the sliders 17 to slide. One end of each of the multiple crank arms 16 away from the moving blocks 15 is rotatably connected to a slider 17. The function of the slider 17 is to drive the fixed block 19 to move. Fixed blocks 19 are fixedly connected to the bottoms of the two sliders 17. Both fixed blocks 19 are made of rubber, and rubber can prevent slipping. The two fixed blocks 19 are in contact with the inner wall of the base 1. The fixed blocks 19 can be in contact with the inner wall of the base 1 to prevent the pipe body 2 from slipping out of the base 1. A fixed rod 18 is fixedly connected inside the pipe body 2. The function of the fixed rod 18 is to support the sliding of the sliders 17. The two sliders 17 slide on the left and right ends of the fixed rod 18 respectively.

The base 1 can play a role in fixing and supporting the pipe body 2, and the upper end surface of the base 1 can provide support for pipe groove processing drills.

[0025] Working principle: When the flange 3 is worn out too much and needs to be replaced or different flange end face processing training is carried out, the staff manually pulls up the handle 12, driving the round rod 10 to slide in the disassembly block 5 towards the staff direction, thereby driving the disassembly strip 8 to slide out of the installation block 6 in the disassembly block 5, so as to achieve the effect of quickly disassembling and replacing the flange 3. The slide rods 24 on both sides of the round rod 10 are used to assist the staff to ensure that the position of the round rod 10 remains unchanged when pulling, playing a limiting role. When the staff needs to disassemble the base 1 for convenient equipment transportation or use the upper end surface of the base 1 for pipe groove processing drills, the staff rotates the turntable 13, thereby driving the bidirectional threaded rod 14 to rotate, and then driving the moving block 15 to slide on the bidirectional threaded rod 14. The sliding of the moving block 15 drives the crank arm 16 to rotate, pulling the sliders 17 sliding on the fixed rod 18 to slide towards each other, driving the fixed blocks 19 away from the inner wall of the pipe body 2, so as to achieve the effect of quickly disassembling the base 1 and facilitating transportation or providing a simulation of pipe groove processing drills.
