[0025] Both sides of the chip collection hopper 22 are equipped with clamping assemblies 3. Each clamping assembly 3 includes a second cylinder 31 located on the outside of the chip collection hopper 22. The mounting end of the second cylinder 31 is installed correspondingly to the outside of the chip collection hopper 22 and is fixedly connected to the chip collection hopper 22. The output end of the second cylinder 31 passes through the chip collection hopper 22 and is equipped with a push plate 32. Both sides of the chip collection hopper 22 have shaft holes. The output end of the second cylinder 31 passes through the shaft holes and is installed correspondingly to one side of the push plate 32 and is fixedly connected to one side of the push plate 32. Two sets of... The rubber clamp 33 is installed at one end corresponding to one side of the push plate 32. The rubber clamp 33 is fixedly connected to the push plate 32. One side of the rubber clamp 33 is arc-shaped. The arc-shaped design of the rubber clamp 33 can better stabilize the small-diameter stainless steel pipe and protect the stainless steel pipe from being crushed due to excessive clamping force. The clamping component 3 can stably clamp the small-diameter stainless steel pipe during grinding and polishing operations, effectively preventing the steel pipe from shaking during polishing and improving polishing quality and efficiency.

[0026] A receiving rack 4 is provided at one end of the auxiliary frame 21 away from the frame 11. The mounting end of the receiving rack 4 is installed corresponding to the upper side of the auxiliary frame 21. The mounting end of the receiving rack 4 is fixedly connected to the auxiliary frame 21. The upper part of the receiving rack 4 is arc-shaped. The receiving rack 4 can receive and unload polished small-diameter stainless steel pipes.

[0027] A central control panel 5 is installed on the auxiliary frame 21 on one side of the receiving rack 4. The mounting end of the central control panel 5 is installed on the upper side of the auxiliary frame 21, and the mounting end of the central control panel 5 is fixedly connected to the auxiliary frame 21. The drive motor 124, cylinder 131, electric push rod 24, polishing motor 26 and cylinder 31 are all electrically connected to the central control panel 5. The central control panel 5 facilitates the operator to quickly set various parameters of the device, greatly reducing the difficulty of operation and improving work efficiency.

[0028] In this embodiment, the operator powers on the drive motor 124, cylinder 131, electric push rod 24, and polishing motor 26 via the central control panel 5. The operator then adjusts the feeding mechanism 12 according to the outer diameter parameters of the small-diameter stainless steel pipe to be polished. At this time, cylinder 131 drives the two feeding mechanisms 12 to move synchronously via the connecting plate 132. The feeding mechanism 12 moves along the limiting groove 8 via the guide block below the assembly frame 121, allowing the two assembly frames 121 to slide closer to or further away from each other, thus adjusting the two feeding mechanisms 12 to be aligned with the pipe to be polished. The size parameters of the stainless steel tubes are matched with each other. Then, the operator places one end of the small-diameter stainless steel tube on the support roller 142 between the two sets of feeding mechanisms 12, so that the outer side of the stainless steel tube is in contact with the conveyor belt 123. At this time, the operator turns on the drive motor 124. The drive motor 124 drives a set of conveyor rollers 122 to rotate. The rotation of the conveyor rollers 122 drives the conveyor belt 123 to rotate as well. When the conveyor belt 123 is rotating, each set of conveyor rollers 122 rotates as well. The rotation of the conveyor belt 123 drives the stainless steel tube to perform feeding operations.

[0029] When the stainless steel pipe is conveyed to the chip collection hopper 22, cylinder 2 31 pushes the push plate 32. The movement of the push plate 32 causes the rubber clamping pads 33 to move accordingly. Thus, the stainless steel pipe is firmly clamped by multiple sets of rubber clamping pads 33 that move closer to one side of the two sets of push plates 32. Then, the operator operates the electric push rod 24, which drives the polishing roller 27 through the roller frame 25 to adjust the height, so that the polishing roller 27 is in close contact with the outer surface of the stainless steel pipe. Then, the polishing motor 26 operates, which drives the polishing roller 27 to polish the stainless steel pipe. After the polishing is completed, one end of the stainless steel pipe is conveyed to the receiving rack 4 for support, thus completing the polishing operation of the stainless steel pipe.

[0030] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
