Each of the two slide plates 10 is fixedly installed with a hanger 11 at its bottom. Each of the two hangers 11 is fixedly installed with a grinder 12.

[0023] Mounting seats 27 are fixedly installed on opposite sides of the first fixed seat 6 and the second fixed seat 7. A lever 25 is slidably connected within each mounting seat 27. A spring 26 is fixedly installed at the bottom of each lever 25, and the bottom of each spring 26 is fixedly installed within the bottom of the mounting seat 27. A locking rod 23 is fixedly installed at the top of each lever 25. Locking holes 24 are provided on each of the two rotating wheels 21. The tops of the two locking rods 23 extend into the corresponding locking holes 24. This design facilitates the use of the equipment. Multiple locking holes 24 are provided, and these holes 24 are arranged circumferentially on the rotating wheels 21. This design facilitates the use of the equipment. Each clamp... Slider 18 is fixedly installed on both sides of the base 16. Each clamping groove 15 has a groove 17 corresponding to the two sliders 18. The sliders 18 are slidably connected in the groove 17. The sliders 18 can limit the position of the clamping base 16. A motor 8 is fixedly installed on the left side of the base frame 2. The output end of the motor 8 is fixedly installed on the threaded rod 4. The rotation of the threaded rod 4 by the motor 8 is beneficial to the use of this equipment.

A PLC controller 3 is fixedly installed on the right side of the base frame 2. The PLC controller 3 facilitates the control of the operation of this equipment.

[0024] Working principle: In use, the first fixed seat 6 and the second fixed seat 7 are located on the lower part of the mounting base 27, away from each other. A purging nozzle can be installed and connected to an external air pump. During grinding, the composite steel pipe body 13 to be ground is inserted into the clamping groove 15 on the first fixed seat 6, located at the lower part of the clamping seat 16, so that the rear end of the composite steel pipe body 13 abuts against the front end of the L-shaped positioning frame 14. Then, the spring 26 is pressed down by the lever 25, causing the locking rod 23 to descend and extend out of the locking hole 24. At this time, the adjusting screw 20 can be rotated by the rotating wheel 21. Since the extension rod 22 is provided with a thread corresponding to the adjusting screw 20, the adjustment screw 20 can be rotated. The extension rod 22 drives the clamping seat 16 to slide downwards and clamp the composite steel pipe body 13. Then, the lever 25 is released. At this time, the spring 26 drives the lever 25 and the locking rod 23 to rise, so that the locking rod 23 extends into the corresponding locking hole 24 to fix and limit the rotating wheel 21. Then, the grinding switch is turned on. At this time, the motor 8 works and drives the threaded rod 4 to rotate forward, so that the moving table 5 slides to the right in the base frame 2. When the first fixed seat 6 slides between the two grinding machines 12, the second fixed seat 7 extends out of the frame 1. At this time, the two output ends of the bidirectional cylinder 9 drive the two slide plates 10, the hanger 11 and the two grinding machines 12 to move towards the ground. As they slide closer to each other, two grinding machines 12 operate simultaneously, grinding the front and rear ends of the composite steel pipe body 13 at the same time using the grinding wheels on the grinding machines 12. During the grinding process, the operator can pre-install other composite steel pipe bodies 13 into the second fixed seat 7, or remove the ground composite steel pipe body 13 from the second fixed seat 7. After the composite steel pipe body 13 in the first fixed seat 6 is ground, the motor 8 drives the threaded rod 4 to reverse, causing the moving table 5 to slide to the left, allowing the second fixed seat 7 to enter the frame 1. At the same time, the first fixed seat 6 extends out of the frame 1, allowing the nozzle to move left and right on the moving table 5. During the process, the waste attached to the threaded rod 4 is blown away. The circuit connection methods, mechanical structures, and connection relationships not mentioned in this specification are all conventional technical means in this field, so they will not be described in detail. This end grinding device for ceramic-lined composite steel pipes is easy to use. The above components can grind the front and rear ends of the composite steel pipe body 13 at one time, reducing the number of operation steps in the grinding process and greatly reducing the workload of the workers. At the same time, the waiting time during the grinding process can be used to disassemble and assemble other composite steel pipe bodies 13, shortening the overall time in the batch processing process, thereby further improving the processing efficiency.
