Description

Technical Field

[0002] Pipe finishing is a mechanical processing process used to improve the surface quality of pipes. It involves the use of specific tools and techniques to reduce the roughness of the pipe surface, improve dimensional accuracy, and improve the surface geometry. Finishing usually includes three stages: coarse grinding, semi-finishing grinding, and finishing grinding. Each stage is designed to gradually improve the surface quality of pipes. During the finishing process, a variety of different grinding materials and auxiliary equipment may be used, such as vibrating grinding and finishing machines, conical resin grinding stones, mirror polishing abrasives, etc. These tools and materials help remove burrs, oxide scales, and further reduce surface roughness, ultimately achieving a mirror-like gloss effect.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-6 A stainless steel reducer fine grinding device comprises a support platform 1, a fixing mechanism 2 is arranged above the support platform 1, and an adjusting mechanism 3 is arranged inside the support platform 1.

[0035] The fixing mechanism 2 includes a support frame 201, the bottom surface of the support frame 201 is fixedly connected to the upper surface of the support platform 1, the inner wall of the support frame 201 is rotatably connected to two rotating shafts 202, the outer surface of each rotating shaft 202 is slidably connected to a limit ring 208, the inner top wall of the support frame 201 is fixedly connected to a dual-axis forward and reverse motor 203, the two output ends of the dual-axis forward and reverse motor 203 are respectively fixed to one end of two first threaded rods 204 through a coupling, the outer surface of each first threaded rod 204 is threadedly connected to a moving block 205, the outer surface of each moving block 205 is slidably connected to the inner wall of the support frame 201, the bottom surface of each moving block 205 is fixedly connected to a moving frame 206, the side surfaces of the two moving frames 206 that are close to each other are fixedly connected to two low-friction rubber pads 207, and the side surfaces of each group of low-friction rubber pads 207 that are close to each other are in contact with the outer surface of the limit ring 208.

[0036] Four supporting legs 4 are fixedly connected to the bottom surface of the support platform 1, and the bottom surface of each supporting leg 4 is fixedly connected to a base 5. By setting the supporting legs 4 and the base 5, a good supporting effect can be provided for the device, so that it can work stably and avoid position displacement during use.

[0037] Two reinforcement blocks 6 are fixedly connected to both side surfaces of the support frame 201, and the bottom surface of each reinforcement block 6 is fixedly connected to the upper surface of the support platform 1. By setting the reinforcement blocks 6, the connection effect between the support frame 201 and the support platform 1 can be further increased, avoiding separation during long-term use and improving the service life of the device.

[0038] The upper surface of the support frame 201 is fixed to the mounting ends of two symmetrically arranged rotating motors 7. Four gears 8 are arranged on the outer side of the support frame 201, wherein the inner walls of two gears 8 are respectively fixedly connected to the outer surfaces of the power output ends of the two rotating motors 7, and the inner walls of the other two gears 8 are respectively keyed and fixed to the outer surfaces of the two rotating shafts 202. By arranging the rotating motors 7 and the gears 8, the power required for the rotation of the rotating shafts 202 can be provided, and at the same time, the gears 8 facilitate the transmission of power, thereby facilitating use.

[0039] Both side surfaces of each gear 8 are fixedly connected to limiting plates 9, and the outer surface of each group of gears 8 is meshedly connected with a toothed belt 10. By setting the limiting plates 9 and the toothed belt 10, the toothed belt 10 can facilitate the transmission of power to the gear 8 and the rotating shaft 202. At the same time, the limiting plates 9 can limit the toothed belt 10 to avoid displacement during use.

[0040] Two limit rings 11 are fixedly connected to the outer surface of each rotating shaft 202, and the side surfaces of each set of limit rings 11 that are close to each other are in contact with the outer surface of the support frame 201 and can rotate. Each rotating shaft 202 can move through the two side walls of the support frame 201. By setting the limit rings 11, a good stabilizing effect can be achieved for the rotating shaft 202 to prevent position displacement during rotation.

[0041] The ends of the two first threaded rods 204 that are away from each other are fixedly connected to bearings 14, and the side surfaces of the two bearings 14 that are away from each other are fixedly connected to the inner wall of the support frame 201. By setting the bearings 14, the firmness of the first threaded rods 204 during rotation can be further improved, allowing them to rotate more smoothly and stably.

[0042] The device also includes a switch, a power supply, a microcomputer, a controller and other devices. The microcomputer can issue instructions through the controller to enable the first micromotor, 306, the second micromotor 16 and the electric telescopic rod 304 to be powered on and work according to the instructions. The electric telescopic rod 304 needs to use a high-precision electric push rod due to the need for grinding, which can be a product of Inshi Robot Company. The device realizes power transmission and communication through wires.

[0043] The specific implementation method of this embodiment is: first, the power supply of the dual-axis forward and reverse motor 203 is turned on so that it can be in a stable power-on state, and then the reducer is sleeved on the two rotating shafts 202. It should be noted that the diameters of the opposite ends of the two rotating shafts 202 for plugging in the reducer can be different, thereby meeting the requirements of different diameters at both ends of the reducer, thereby achieving that the two rotating shafts 202 just fill the inner diameter of the reducer to achieve better radial fixation, and when the reducer is initially fixed, the concentricity of the reducer can be increased and the limit ring 208 can be prevented from falling and being damaged due to loose fixation. At the same time, by moving the two limit rings 208 under the drive of the two moving frames 206, the limit ring 208 can be subjected to more uniform force to avoid unidirectional deviation. At the same time, in terms of the fixing effect on the reducer, the surface of the reducer to be finely ground will not be occupied, thereby making the area of ​​fine grinding of the reducer larger and achieving a single fine grinding effect.

[0044] At the same time, the double-axis forward and reverse motor 203 is turned on. The rotation of the double-axis forward and reverse motor 203 can drive the two first threaded rods 204 to rotate. Under the action of the rotation of the first threaded rod 204, the two moving blocks 205 and the moving frame 206 can be driven to move, so as to push the two limit rings 208 to squeeze and fix the reducer. Since the friction force of the low-friction rubber pad 207 is small, it can be convenient to drive the reducer to rotate during subsequent fine grinding. At the same time, with the cooperation of the two limit rings 208, it is convenient to squeeze and fix reducers of different thicknesses and sizes and drive the reducer to rotate.

[0045] Example 2: Please refer to Figure 1-6 The adjusting mechanism 3 includes a bidirectional threaded rod 301, the outer surface of the bidirectional threaded rod 301 is rotatably connected to the inner wall of the support platform 1, the outer surface of the bidirectional threaded rod 301 is threadedly connected to two moving frames 302, the outer surface of each moving frame 302 is slidably connected to the inner wall of the support platform 1, the inner wall of each moving frame 302 is fixedly connected to a first micro motor 306, the output end of each first micro motor 306 power is fixedly connected to a second threaded rod 307, one end of each second threaded rod 307 away from the first micro motor 306 is rotatably connected to the inner wall of the moving frame 302, the outer surface of each second threaded rod 307 is threadedly connected to a support block 303, the outer surface of each support block 303 is slidably connected to the inner wall of the moving frame 302, the upper surface of each support block 303 is fixedly connected to an electric telescopic rod 304, and the telescopic end of each electric telescopic rod 304 is fixedly connected to a fixed frame 305;

[0046] The front side of the bidirectional threaded rod 301 is fixedly connected with a rotating block 12, and the outer surface of the rotating block 12 is provided with six anti-skid grooves 13. By providing the rotating block 12 and the anti-skid grooves 13, it is convenient for the staff to manually rotate the bidirectional threaded rod 301 for rotation, and the anti-skid grooves 13 can prevent the hand from slipping during rotation;

[0047] Both sides of each moving frame 302 are fixedly connected with sliders 15, and the outer surface of each slider 15 is slidably connected to the inner wall of the support platform 1. By providing the sliders 15, a good limiting effect can be played for the moving frame 302, and the moving frame 302 can also be assisted in moving;

[0048] The right side of each fixing frame 305 is fixedly connected with a second micro motor 16, the power output end of each second micro motor 16 passes through the fixing frame 305 and extends to the outside of the fixing frame 305, and the power output end of each second micro motor 16 is fixedly connected with a grinding block 17. By setting the second micro motor 16 and the grinding block 17, the second micro motor 16 can drive the grinding block 17 to rotate, thereby being able to perform fine grinding on the surface of the reducer.

[0049] The specific implementation method of this embodiment is as follows: first, the power supply of the first micro motor, 306, the second micro motor 16 and the electric telescopic rod 304 is turned on, so that they can be in a stable power-on state to avoid power outages during use. Then the staff manually rotates the bidirectional threaded rod 301, and the bidirectional threaded rod 301 can drive the two moving frames 302 to move. During the movement of the moving frames 302, the upper fine grinding device can be driven to adjust and move. Then, the electric telescopic rod 304 is turned on. After the electric telescopic rod 304 is turned on, it can push the fine grinding device to rise until it rises to the center horizontal height of the reducer, thereby facilitating the fine grinding work. Finally, the second micro motor 16 is turned on. After the second micro motor 16 is turned on, it can drive the second threaded rod 307 to rotate. The rotation of the second threaded rod 307 can drive the support block 303 and the upper fine grinding device to move until they move to a suitable fine grinding position, thereby facilitating subsequent fine grinding work.

[0050] Example 3: Please refer to Figure 1-6The specific implementation method of this embodiment is as follows: first, the staff turns on the power of the rotating motor 7, the double-axis forward and reverse motor 203, the electric telescopic rod 304, the first micro motor 306, the second micro motor 16 and the electric telescopic rod 304, so that they can be in a stable power-on state, and then the reducer is set on the two rotating shafts 202, and the double-axis forward and reverse motor 203 is turned on at the same time. The rotation of the double-axis forward and reverse motor 203 can drive the two first threaded rods 204 to rotate. Under the action of the rotation of the first threaded rod 204, the two moving blocks 205 and the moving frame 206 can be driven to move, so that The two limiting rings 208 can be pushed to squeeze and fix the reducer, and with the cooperation of the two limiting rings 208, it is convenient to squeeze and fix the reducers of different thicknesses and sizes and drive the reducer to rotate. After the reducer is squeezed and fixed, the staff manually rotates the two-way threaded rod 301, and the two-way threaded rod 301 can drive the two moving frames 302 to move. During the movement of the moving frame 302, the upper fine grinding device can be driven to adjust and move, and then the electric telescopic rod 304 is turned on. After the electric telescopic rod 304 is turned on, it can push the fine grinding device to rise until it rises to the reducer. The center is horizontal, so as to facilitate the fine grinding work, and finally the second micro motor 16 is turned on. After the second micro motor 16 is turned on, it can drive the second threaded rod 307 to rotate. The rotation of the second threaded rod 307 can drive the support block 303 and the fine grinding device above to move until they move to a suitable fine grinding position. Finally, the first micro motor 306, the second micro motor 16 and the rotating motor 7 can be turned on again to perform fine grinding work. After the rotating motor 7 is turned on, it can drive the gear 8 and the toothed belt 10 to rotate. When the toothed belt 10 rotates, it can drive the rotating shaft 202 and the limit ring 208 to rotate. Since the friction force of the low-friction rubber pad 207 is relatively small, it does not prevent the limit ring 208 from rotating while squeezing the reducer. At the same time, the limit ring 208 can drive the reducer to rotate when rotating, thereby facilitating the fine grinding of the surface of the reducer. The first micro motor 306 and the second micro motor 16 can respectively drive the grinding block 17 to rotate and move, so that the fine grinding work can be performed quickly. Since the surface of the reducer has a slope, the distance between the grinding block 17 and the reducer changes. During the fine grinding process, the staff is also required to manually adjust the distance of the grinding block 17 through the bidirectional threaded rod 301.
