[0034] In order to solve the technical problems in the background art, as shown in the Figures 1-5 The present application provides a technical solution: a stainless steel pipe surface treatment device, characterized by:

[0035] The mounting plate 1 is used to support all components of the entire stainless steel pipe surface treatment device. On the surface of the mounting plate 1, a plurality of mutually parallel slide rails 2 are provided, which are used to guide and fix the position of other components. The fixing block 3 is U-shaped, and the bottom of the fixing block 3 is designed with a groove matched with the slide rail 2, which ensures that the fixing block 3 can be stably installed on the mounting plate 1. The two side walls of the fixing block 3 will be used to install the rotating shaft 4. The rotating shaft 4 is a key component fixed on the two side walls of the fixing block 3, which is used to support and rotate the first grinding wheel 5. The first grinding wheel 5 is sleeved on the rotating shaft 4 and is designed to rotate with the rotating shaft 4, which is used for polishing the outer surface of the stainless steel pipe. The first motor 6 is installed on the fixing block 3 and connected with the rotating shaft 4, which is responsible for driving the rotation of the rotating shaft 4 and the first grinding wheel 5. The supporting plate 7 is provided on the mounting plate 1 and is used to support the stainless steel pipe to ensure the stability of the pipe during the treatment process. The connecting plate 8 is provided on the side wall of the fixing block 3, and a plurality of connecting rods 9 are provided on the connecting plate 8, which extend along the axis of the grinding wheel and are used to fix the second motor 10. The second motor 10 is fixed in the space enclosed by the connecting rods 9, and a circular mounting block 11 is provided on the rotating shaft of the second motor 10. The side wall of the circular mounting block 11 has a limiting groove 12, and a plurality of independent cavities 13 are uniformly arranged in the radial direction inside the circular mounting block 11. The side wall of the cavity 13 is provided with a through hole 14. The L-shaped connecting rod 15 is arranged in the cavity 13, one end of the L-shaped connecting rod 15 passes through the through hole 14 and connects with the arc-shaped sanding plate 16, and the arc-shaped sanding plate 16 is arranged in the limiting groove 12 and is used for polishing the inner surface of the stainless steel pipe. The spring 17 is arranged in the cavity 13, and the two ends of the spring 17 abut against the L-shaped connecting rod 15 and the inner wall of the cavity 13, respectively. Under the drive of the second motor 10, the arc-shaped sanding plate 16 moves away from the limiting groove 12 under the action of centrifugal force; and under the action of the L-shaped connecting rod 15 and the spring 17, the arc-shaped sanding plate 16 is reset.

[0036] In use, the stainless steel pipe is placed on the supporting plate 7 to ensure that the pipe is centered and stable. Start the first motor 6 to make the first grinding wheel 5 start rotating to polish the outer surface of the stainless steel pipe. When the pipe is sleeved on the arc-shaped sanding plate 16, start the second motor 10 to drive the arc-shaped sanding plate 16 to rotate and extend towards the inner wall of the pipe to polish the inner surface of the stainless steel pipe. The arc-shaped sanding plate 16 moves away from the limiting groove 12 under the action of centrifugal force to process the inner surface. The pipe continues to advance to realize simultaneous processing of the inside and outside. After the processing is completed, the second motor 10 is turned off, and the arc-shaped sanding plate 16 is reset under the action of the L-shaped connecting rod 15 and the spring 17, preparing for the next processing.

[0037] Further, the first grinding wheel 5 is designed as a cylindrical shape, which makes the contact area of the first grinding wheel 5 with the stainless steel pipe larger, thereby improving the grinding efficiency and uniformity. The first grinding wheel 5 is composed of a solid metal core and an outer abrasive layer, and the abrasive layer can be various sizes of abrasives to adapt to different surface treatment needs.

[0038] It is worth noting that the mounting bracket 18 is installed on the mounting plate 1, which is a movable connection, while ensuring its stability and load-bearing capacity. The second grinding wheel 19 is installed on the mounting bracket 18, which is used for additional surface treatment of stainless steel pipes. The second grinding wheel 19 is a disc or cylindrical grinding wheel, or other shapes, according to the processing needs to choose the appropriate grinding wheel type and material. The pulley assembly 20 is a transmission device connecting the third motor 21 and the second grinding wheel 19. It is composed of one or more pulleys and belts, which is used to transmit the rotating power of the motor to the second grinding wheel 19, achieving high-speed rotation of the second grinding wheel 19. The third motor 21 is installed on the mounting bracket 18 and connected with the pulley assembly 20. This motor is responsible for driving the pulley assembly 20, and then driving the second grinding wheel 19 to rotate, grinding the stainless steel pipe.

[0039] It is worth noting that the bottom of the mounting bracket 18 is designed with one or more grooves, which are matched with the slide rails 2 on the mounting plate 1. This design allows the mounting bracket 18 to move smoothly on the slide rails 2, making it easy to adjust the relative position of the second grinding wheel 19 to the stainless steel pipe, to adapt to the surface treatment needs of stainless steel pipes of different diameters. By moving the mounting bracket 18 on the slide rails 2, the position of the second grinding wheel 19 can be easily adjusted to meet different processing requirements. The design of the groove also helps to quickly position the mounting bracket 18, ensuring the accuracy and repeatability of the processing process.

[0040] It is worth noting that the main function of the protective cover 22 is to protect against injury caused by polishing fine particles during operation. At the same time, it can prevent clothes, hands or other objects from being entangled by the rotating belt and pulley, ensuring the safety of the operation process. The protective cover 22 is usually made of solid metal or plastic materials, designed to completely cover the rotating part of the pulley assembly 20. The protective cover 22 is installed: the protective cover 22 is fixed around the pulley assembly 20 by bolts, buckles or other fasteners. The design takes into account the ease of disassembly to facilitate the maintenance and repair of the pulley assembly 20.

[0041] Further, the bidirectional screw rod 23 is used to realize the precise movement and positioning of the fixed block 3 and the mounting bracket 18 along the mounting plate 1. This design allows the position of the fixed block 3 and the mounting bracket 18 to be adjusted to accommodate stainless steel pipes of different diameters, achieving more flexible surface treatment. The bidirectional screw rod 23 is a transmission element composed of a threaded rod and a matching threaded hole, which can move in two directions to achieve precise position adjustment. The mounting ear 24 is a component fixed to the fixed block 3 and the mounting bracket 18, which has a threaded groove inside that matches the bidirectional screw rod 23. The design of the mounting ear 24 allows the bidirectional screw rod 23 to pass through and engage smoothly, achieving the movement of the fixed block 3 and the mounting bracket 18.

[0042] It is worth mentioning that the main purpose of the parallel arrangement of the bidirectional screw 23 with the slide rail 2 is to ensure the stability and consistency of the fixed block 3 and the mounting bracket 18 during movement along the mounting plate 1. This parallel arrangement helps to reduce friction and wear, improve the accuracy of adjustment, and ensure the smoothness of the device during operation.

[0043] It is worth mentioning that the knob 25 is used to manually operate the bidirectional screw 23 to achieve precise movement and positioning of the fixed block 3 and the mounting bracket 18 along the mounting plate 1. The knob 25 provides a simple method to adjust the device without the need for additional tools for fine-tuning. The knob 25 is usually made of plastic or metal and designed in a shape that is easy to hold and rotate, such as a circle or a star.

[0044] It is worth mentioning that the main function of the heightening plate 26 is to increase the height of the mounting plate 1, thereby providing additional stability and support. This design is particularly suitable for situations that require operation at different heights, and also helps to protect the bottom of the mounting plate 1 from damage. The heightening plate 26 is designed to be connected to the bottom of the mounting plate 1 and form an I-shaped structure. This structure is widely used due to its strong load-bearing capacity and torsional resistance. The I-shaped structure is composed of the mounting plate 1 and the heightening plate 26, where the heightening plate 26 is located at the bottom of the mounting plate 1, forming a reverse "T" cross-section. This structure provides good load-bearing capacity and bending resistance. The heightening plate 26 is installed at the bottom of the mounting plate 1 by welding, bolting or other appropriate fixing methods. The installation must be firm to ensure the stability of the structure during operation of the device.

[0045] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
