Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Combination Figure 1-3 As shown, an integrated grinding and polishing device for stainless steel pipes includes a steel pipe conveying mechanism and a grinding and polishing chamber disposed in the middle of the steel pipe conveying mechanism. The conveying mechanism is also provided with a first driving mechanism for driving the stainless steel pipe 10 to rotate. The grinding and polishing chamber consists of an upper body 1 and a lower body 2; The upper body 1 is provided with a rotating shaft 3, and multiple grinding discs 4 and multiple polishing discs are arranged at equal intervals on the rotating shaft 3. The outer side of the upper body 1 is also provided with a second driving mechanism 5 to drive the rotating shaft 3 to rotate. The lower body 2 is provided with a chip collection chamber 6, and a dust collection device 7 is connected to one side of the chip collection chamber 6; The lower body 2 and the upper body 1 are respectively provided with arc-shaped notches 8 corresponding to stainless steel tubes 10 at their front and rear ends, and the inner circumference of the arc-shaped notches 8 is provided with a retaining ring 9 composed of brushes. The upper body 1 is fastened and telescopically connected to the lower body 2.

[0017] The working principle of the above structure is as follows: after the stainless steel tube 10 rotates into the grinding and polishing chamber, it lifts up the grinding discs 4 and polishing discs in sequence. Since the upper body 1 is telescopically connected to the lower body 2, the grinding discs 4 and polishing discs rotate in the opposite direction with the stainless steel tube 10 by rising and abutting against the outer surface of the stainless steel tube 10 to grind and polish the stainless steel tube 10. Since the upper body 1 and the lower body 2 are relatively closed, the debris and dust generated during the polishing process fall into the chip collection chamber 6 of the lower body 2 and are sucked out by the dust collection device 7.

[0018] The advantages of the above structure are that it is simple to construct and can complete the grinding and polishing of stainless steel pipe 10 in one go. The debris and dust generated during the grinding and polishing process are removed in real time, which can keep the workshop clean.

[0019] In another embodiment, combined Figure 1-3 As shown, a guide post 11 is provided at each of the four corners of the top of the lower body 2, and a guide hole corresponding to each guide post 11 is provided on the upper body 1. Each guide post 11 passes through the corresponding guide hole. A limiting ring 12 is provided on each guide post 11 above the upper body 1, and a spring 13 is also sleeved on the guide post 11 located between the upper body 1 and the lower body 2. The limiting ring 12 limits the height of the upper body 1 to prevent the upper body 1 from directly detaching from the guide post 11. The spring 13 supports the upper body 1, so that the upper body 1 can maintain a downward trend under its own weight, and also prevents the weight of the upper body 1 from being completely applied to the stainless steel tube 10 passing through the grinding and polishing chamber, which would prevent the stainless steel tube 10 from smoothly pushing the grinding disc 4 or polishing disc.

[0020] In another embodiment, such as Figure 1 As shown, each of the grinding discs 4 and polishing discs has a chamfer on the outer periphery of both sides to facilitate the lifting of the grinding discs 4 or polishing discs when the stainless steel tube 10 passes through.

[0021] In another embodiment, such as Figure 1 As shown, the two end faces of the upper body 1 are located on the outer sides of the two end faces of the lower body 2, and the lower body 2 also has a protrusion 14 on each side. The two protrusions 14 are respectively arranged on the inner side of the upper body 1 to prevent the upper body 1 and the lower body 2 from having too large a gap when the upper body 1 is raised, which would cause dust to leak out.

[0022] In another embodiment, such as Figure 1 As shown, the upper body 1 and the lower body 2 each have a connecting end 15 on both sides, and the guide post 11 and the guide hole are respectively set on the corresponding connecting end 15.

[0023] In another embodiment, the second drive mechanism 5 is a motor, which is located at the front end of the upper body 1, and a counterweight 16 is provided at the rear end of the upper body 1 to balance the center of gravity of the upper body 1.

[0024] In another embodiment, the steel pipe conveying mechanism consists of multiple sets of idler rollers 17 and two sets of drive rollers 18. The roller bodies of both the idler rollers 17 and the drive rollers 18 are roller bodies with an arc groove in the middle. The two sets of drive rollers 18 are respectively arranged at the front and rear ends of the grinding and polishing chamber. The two sets of drive rollers 18 are respectively inclined. When the drive rollers 18 rotate, they can drive the steel pipe to rotate and move backward.

[0025] In another embodiment, the arcuate groove of the drive roller 18 is further provided with a rubber layer to increase the friction with the steel pipe and prevent the stainless steel pipe 10 from failing to rotate under the action of the grinding disc 4 or polishing disc.
