[0021] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3 As shown, a stainless steel seamless steel pipe cutting and grinding device comprises a workbench 1, a pipe feeding mechanism 2 arranged at the left end of the workbench 1, a clamping mechanism 3 arranged on the workbench 1 and located at the right end of the pipe feeding mechanism 2, a cutting mechanism 4 connected to the upper right end of the clamping mechanism 3 by lifting, and a grinding mechanism connected to the right end of the workbench 1 by moving left and right;

The mounting frame 6 has a through hole 8 in the middle, and a plurality of guide grooves 9 are arranged on the mounting frame 6 around the through hole 8. A first cylinder 10 is also fixed on the mounting frame 6 at the outer end of each guide groove 9. Each clamping block 7 is slidably connected to the corresponding guide groove 9 and connected to the piston rod of the corresponding first cylinder 10.

[0024] When the steel pipe 11 is input, it passes through the through hole 8. Under the action of the first cylinder 10, each clamping block 7 extends to clamp the steel pipe 11. The cutting mechanism 4 is lowered to cut the end of the steel pipe 11 passing through the clamping mechanism 3. The grinding mechanism moves left to grind the end of the cut steel pipe 11.

[0025] The working principle of the above structure is: the steel pipe 11 to be cut is placed on the pipe feeding mechanism 2, and the pipe feeding mechanism 2 feeds the steel pipe 11 to the right end of the workbench 1. After reaching the appropriate position, the pipe feeding mechanism 2 stops feeding, and the clamping mechanism 3 clamps the steel pipe 11; after clamping, the cutting mechanism 4 is lowered to cut the end of the steel pipe 11. Since the clamping mechanism 3 clamps the end of the steel pipe 11, the steel pipe 11 is not easily displaced during cutting, thereby ensuring the cutting accuracy; after cutting, the cutting mechanism 4 is reset, the clamping mechanism 3 keeps clamping the steel pipe 11, and the grinding mechanism moves to the left so that the grinding disc 15 abuts against the cut end of the steel pipe 11 to grind and remove burrs; after grinding, the grinding mechanism is reset, the clamping mechanism 3 releases the clamping of the steel pipe 11, and the pipe feeding mechanism 2 outputs the steel pipe 11 in the reverse direction to complete one cutting.

[0026] The beneficial effects of the above structure are: simple structure, reasonable layout, can complete the cutting and grinding of the end of the steel pipe 11 at one time, and only workers need to perform auxiliary operations during the processing, which can save manpower and improve processing efficiency.

[0027] In another embodiment, if Figure 1 As shown, the pipe delivery mechanism 2 includes multiple rollers, a transmission chain connecting one end of each roller, and a forward and reverse reduction motor connected to one of the multiple rollers. The forward and reverse reduction motor drives each roller to rotate to drive the steel pipe 11 to be input or output.

[0028] In another embodiment, each of the rollers, transmission chain and forward and reverse reduction motors are arranged on a lifting seat. When processing steel pipes 11 of different specifications, the lifting seat performs corresponding lifting adjustments to make the steel pipe 11 coaxially arranged with the clamping mechanism 3 and the grinding mechanism.

[0029] In another embodiment, if Figure 1 As shown, there are two groups of mounting frames 6 and clamping blocks 7 to ensure stable clamping of the steel pipe 11 .

[0031] In another embodiment, if Figure 1 As shown, the cutting mechanism 4 includes a bracket connected to the bottom of the lifting frame, a cutting saw blade arranged at the left end of the bracket, and a cutting motor arranged at the right end of the bracket.

[0032] In another embodiment, if Figure 1 As shown, the grinding mechanism includes a moving seat 12 , a grinding motor 13 fixed on the top of the moving seat 12 , a connecting rod 14 fixed on the output shaft of the grinding motor 13 , and a grinding disc 15 fixed on the left end of the connecting rod 14 .

[0033] In another embodiment, if Figure 1 As shown, the workbench 1 is provided with a guide rail corresponding to the moving seat 12, and the bottom of the moving seat 12 has a slider, and the slider is fitted on the guide rail.
