[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model provides a steel pipe mouth processing and grinding device, comprising: a base 1;

[0029] Two guide rails 2 are fixed on the top of the base 1, and the base 1 is used to support the guide rails 2. When installing the device, the base 1 can be fixed to the right side of the clamp for clamping the steel pipe. When grinding the pipe mouth of the steel pipe, the lower support plate 3 can be pushed to the far right between the guide rails 2, and then the directions of the No. 1 grinding block 6, the No. 2 grinding block 7 and the No. 3 grinding block 8 can be adjusted. After the adjustment, the lower support plate 3 can be pushed to the left to make the grinding block contact with the pipe mouth of the steel pipe for grinding; a lower support plate 3 is slidably installed between the two guide rails 2, and the lower support plate 3 is used to support the inner support column 9; an upper support plate 4 is arranged on the top of the lower support plate 3, and the upper support plate 4 is used to support the grinding block support shell 5; a grinding block support shell 5 is fixed on the top of the upper support plate 4, and the grinding block support shell 5 is used to grind the No. 1 grinding block 6, the No. 2 grinding block 7 and the No. 3 grinding block 8 Support; a No. 1 grinding block 6, a No. 2 grinding block 7 and a No. 3 grinding block 8 are fixed on the outside of the grinding block support shell 5. The No. 1 grinding block 6 can grind the inner wall edge of the steel pipe mouth, the No. 2 grinding block 7 can grind the cross-section of the steel pipe mouth, and the No. 3 grinding block 8 can grind the outer wall edge of the steel pipe mouth; an inner support column 9 is fixed to the middle position of the top of the lower support plate 3, and the inner support column 9 can rotatably support the upper support plate 4 and the grinding block support shell 5, so as to adjust the orientation of the No. 1 grinding block 6, the No. 2 grinding block 7 and the No. 3 grinding block 8; a positioning pin 10 is also embedded and installed on one side of the top of the grinding block support shell 5, and inserting the positioning pin 10 into the round holes on the round rods on the top of the grinding block support shell 5 and the inner support column 9 can limit the up and down movement of the grinding block support shell 5.

[0030] In the present disclosure, Figure 3 and Figure 4 As shown, the inner support column 9 can slide up and down in the cylindrical groove on the inner side of the bottom of the grinding block support shell 5, and when the grinding block support shell 5 moves to the top on the outside of the inner support column 9, the upper support plate 4 will be separated from the round rod on the top of the lower support plate 3. When adjusting, the grinding block support shell 5 and the upper support plate 4 can be pulled upward to the top on the outside of the inner support column 9, because at this time the upper support plate 4 will be separated from the round rod on the top of the lower support plate 3, so the grinding block support shell 5 and the upper support plate 4 can be rotated and adjusted.

[0031] In the present disclosure, Figure 1-Figure 6 As shown, four round rods are arranged in a ring on the top of the lower support plate 3, and four round holes with corresponding inner diameters are also arranged in a ring on the upper support plate 4. After the direction of the grinding block is rotated, the grinding block support shell 5 and the upper support plate 4 are pushed downward to the bottom. At this time, the round rods on the top of the lower support plate 3 will be re-embedded in the round holes on the upper support plate 4, thereby limiting the rotation of the upper support plate 4 and the grinding block support shell 5, thereby fixing the direction of the grinding block.

[0032] In the present disclosure, Figure 1-Figure 4As shown, grinding block No. 1 6 is a truncated cone-shaped grinding block which is thin on the left and thick on the right, grinding block No. 2 7 is a circular plate-shaped grinding block, and grinding block No. 3 8 is provided with a conical inner groove on the right side. Therefore, grinding block No. 1 6 can grind the inner wall edge of the steel pipe mouth, grinding block No. 2 7 can grind the cross-section of the steel pipe mouth, and grinding block No. 3 8 can grind the outer wall edge of the steel pipe mouth.

[0033] In the present disclosure, Figure 4 and Figure 5 As shown, the inner support column 9 is composed of two sections of cylinders, the bottom of which is a thin cylinder and the top is a thick cylinder. The inner support column 9 can rotatably support the upper support plate 4 and the grinding block support shell 5, so as to adjust the orientation of the grinding block No. 1 6, the grinding block No. 2 7 and the grinding block No. 3 8.

[0034] In the present disclosure, Figure 4 and Figure 6 As shown, two cylindrical grooves are arranged on the inner side of the bottom of the grinding block support shell 5, the inner diameter of the lower cylindrical groove is equal to the outer diameter of the thin cylinder at the bottom of the inner support column 9, and the inner diameter of the upper cylindrical groove is equal to the outer diameter of the thick cylinder at the top of the inner support column 9. The inner support column 9 can rotatably support the upper support plate 4 and the grinding block support shell 5, so as to adjust the orientation of the No. 1 grinding block 6, the No. 2 grinding block 7 and the No. 3 grinding block 8.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, a round rod is also provided on the top of the inner support column 9, and four round holes with an inner diameter equal to the outer diameter of the positioning pin 10 are provided on the top of the round rod. A round hole with an inner diameter equal to the outer diameter of the positioning pin 10 is also provided on the grinding block support shell 5, and when the grinding block support shell 5 moves down to the bottom, the round holes on the grinding block support shell 5 will be aligned with one of the round holes on the top round rod of the inner support column 9. After the orientation adjustment of the No. 1 grinding block 6, the No. 2 grinding block 7 and the No. 3 grinding block 8 is completed, the positioning pin 10 can be reinserted into the round holes on the grinding block support shell 5 and the top round rod of the inner support column 9. In this way, the up and down movement of the grinding block support shell 5 can be limited, thereby ensuring stability during grinding.

[0036] The working principle of this embodiment: when installing this device, the base 1 can be fixed on the right side of the clamp for clamping the steel pipe. When grinding the pipe mouth of the steel pipe, the lower support plate 3 can be pushed to the far right between the guide rails 2, and then the directions of the No. 1 grinding block 6, the No. 2 grinding block 7 and the No. 3 grinding block 8 can be adjusted. The No. 1 grinding block 6 can grind the inner wall edge position of the steel pipe mouth, the No. 2 grinding block 7 can grind the cross-section of the steel pipe mouth, and the No. 3 grinding block 8 can grind the outer wall edge position of the steel pipe mouth. When adjusting, first pull out the positioning pin 10, and then pull the grinding block support shell 5 and the upper support plate 4 upward to the top outside the inner support column 9. Because the upper support plate 4 will be detached from the round rod at the top of the lower support plate 3 at this time, the grinding block support shell 5 and the upper support plate 4 can be rotated and adjusted. After the adjustment, just push the lower support plate 3 to the left to make the grinding block contact with the pipe mouth of the steel pipe for grinding.
