In a magnetic pump, the spacer is located between the rotating inner magnetic rotor and the rotating outer magnetic rotor, playing a role of sealing and isolation. In summary, the problems existing in the prior art are: spacers are usually processed by turning, milling and cutting. A pipe cutting machine is a mechanical equipment for cutting pipes, which can be used in spacer cutting processing. When in use, the spacer is placed on the fixed ring provided by the pipe cutting machine, and then the fixed ring is adjusted by the screw to clamp the spacer front and back to perform the cutting operation.

[0021] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0023] refer to Figure 5 The limiting device 8 includes a limiting block 801. The top of the limiting block 801 passes through the device shell 5 and extends to the outside of the inner cavity of the device shell 5. Two stabilizing holes 802 are provided on the surface of the limiting block 801. The bottom of the inner cavity of the device shell 5 is fixedly connected to two stabilizing frames 803 used in conjunction with the stabilizing holes 802. The surface of the stabilizing frame 803 contacts the inner cavity of the stabilizing hole 802. The bottom of the limiting block 801 is fixedly connected to two springs 804. The bottom of the spring 804 is fixedly connected to the bottom of the inner cavity of the device shell 5.

[0024] With the above solution, by providing the limiting device 8 , when the device housing 5 and the fixing ring 6 are moved to appropriate positions, the limiting device 8 has a limiting effect on the positions of the device housing 5 and the fixing ring 6 .

[0025] refer to Figure 5 The limit block 801 is fixedly connected to the side of the extrusion control shell 7 close to the extrusion rod 9. The inner cavity of the device shell 5 is movably connected to the extrusion rotating shell 10 used in conjunction with the extrusion rod 9 through a rotating shaft. The inner cavity of the extrusion rotating shell 10 is movably connected to the surface of the extrusion rod 9, and the surface of the extrusion control shell 7 is in contact with the inner cavity of the extrusion rotating shell 10.

[0026] The above solution is adopted: by arranging the extrusion rod 9 and the extrusion rotating shell 10, when the extrusion rotating shell 10 rotates through the rotating shaft, an extrusion force can be generated on the extrusion rod 9, and the extrusion rod 9 subjected to the extrusion force can drive the limit block 801 to move.

[0027] refer to Figure 5 The inner cavity of the device shell 5 is fixedly connected to a moving rod 11 used in conjunction with the extrusion control shell 7, and the surface of the moving rod 11 contacts the inner cavity of the extrusion control shell 7.

[0028] With the above solution, by providing the moving rod 11 , the extrusion control housing 7 is pulled upward to drive the extrusion control housing 7 to move along the surface of the moving rod 11 , and the moving rod 11 has a limiting effect on the moving position of the extrusion control housing 7 .

[0029] refer to Figure 4 An outer shell 12 is provided on the opposite side of the two extrusion control shells 7. The inner cavity of the outer shell 12 is movably connected to the inner shell 13. The surfaces of the inner shell 13 and the outer shell 12 are fixedly connected to the surface of the extrusion control shell 7.

[0030] The above solution is adopted: by setting the outer shell 12 and the inner shell 13, when the extrusion control shell 7 moves, the outer shell 12 will be driven to move along the surface of the inner shell 13. The coordinated use of the outer shell 12 and the inner shell 13 has a limiting effect on the moving position of the extrusion control shell 7.

[0031] refer to Figure 3 The tops of the inner cavities of the fixed adjustment frame 3 and the movable adjustment frame 4 are both provided with limiting grooves 14 for use with the limiting block 801. The surface of the limiting block 801 contacts the inner cavity of the limiting groove 14. There are several limiting grooves 14, which are evenly distributed on the tops of the inner cavities of the fixed adjustment frame 3 and the movable adjustment frame 4.

[0032] The above solution is adopted: by setting the limit groove 14, when the device shell 5 moves to the appropriate position, the squeezing control shell 7 is released, and the restoring force generated by the spring 804 restoring its shape will drive the limit block 801 to be stuck into the inner cavity of the limit groove 14. The coordinated use of the limit block 801 and the limit groove 14 has a limiting effect on the position of the device shell 5.

[0033] refer to Figure 2 A slider 15 is fixedly connected to the side of the device shell 5 away from the fixed ring 6. Two sliding holes 16 for use with the slider 15 are provided on the top of the fixed adjustment frame 3 and the movable adjustment frame 4. The surface of the slider 15 is movably connected to the inner cavity of the sliding hole 16.

[0034] The above solution is adopted: by setting the slider 15 and the sliding hole 16, when the device housing 5 moves, the slider 15 will be driven to move along the inner cavity of the sliding hole 16. The cooperation of the slider 15 and the sliding hole 16 has a limiting effect on the moving position of the device housing 5.

[0035] The working principle of this utility model:

[0036] During use, when the pipe cutting machine used for spacer cutting processing needs to stabilize and limit spacers of different lengths, the operator first pulls the extrusion control shell 7 to the top, and at the same time drives the extrusion control shell 7 to move along the surface of the moving rod 11. When the extrusion control shell 7 moves, it will generate an extrusion force on the extrusion rotating shell 10. The extrusion rotating shell 10 subjected to the extrusion force will rotate along the surface of the extrusion rod 9 through the rotating shaft. The extrusion rod 9 subjected to the extrusion force will move downward. When the extrusion rod 9 moves, it will drive the limit block 801 to move downward. When the limit block 801 moves, it will drive the stabilizing hole 802 to move along the surface of the stabilizing frame 803. The force generated when the limit block 801 moves causes the spring 804 to undergo elastic deformation. When the limit block 801 is completely moved to the inner cavity of the device shell 5, the device shell 5 is pulled to the left or right. When the device shell 5 moves It will drive the slider 15 to move along the inner cavity of the sliding hole 16, and at the same time drive the fixing ring 6 to move to the left or right. When the four fixing rings 6 move to a position where the limiting spacer can be stabilized, the extrusion control shell 7 is released, and the restoring force generated by the spring 804 restoring its shape will drive the limiting block 801 to be stuck in the inner cavity of the limiting groove 14. The coordinated use of the limiting block 801 and the limiting groove 14 has a limiting effect on the position of the device shell 5 and the fixing ring 6. Then the spacer can be placed in the inner cavity of the fixing ring 6, and then the position of the movable adjustment frame 4 can be adjusted by rotating the screw. When the movable adjustment frame 4 moves, it will drive the outer shell 12 to move along the surface of the inner shell 13. When the movable adjustment frame 4 moves, it will drive the fixing ring 6 to move to a position in close contact with the surface of the spacer. At this time, the pipe cutting machine used for the spacer cutting process completes the stable limiting of spacers of different lengths.

[0037] To sum up: the cutting device for spacer processing solves the problem that the spacer is usually processed by turning, milling and cutting by setting a limit device 8, a limit block 801, a stabilizing hole 802, a stabilizing frame 803, a spring 804 and a limit groove 14. The pipe cutting machine is a mechanical equipment for cutting pipes and can be applied to the spacer cutting process. When in use, the spacer is placed on the fixed ring provided by the pipe cutting machine, and then the fixed ring is adjusted by the screw to clamp the spacer front and back to perform the cutting operation. The lengths of the uncut spacers are different, and the spacing between the left and right fixing rings is fixed and cannot be adjusted. If the distance between the left and right fixing rings cannot be adjusted, it is impossible to provide more stable support for spacers of different lengths. However, the pipe cutting machine used in the existing spacer cutting process does not have a component for stabilizing and limiting spacers of different lengths.
