Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1-Figure 7The device for grinding inner holes of pipes shown in the figure comprises: a grinding table 1, a rectangular tube 2 and a camera 36. Tube clamping mechanisms are arranged on both sides of the upper surface of the grinding table 1. The rectangular tube 2 is clamped between the two tube clamping mechanisms. An L-shaped frame 3 is fixedly connected to one end of the grinding table 1. A support table 4 is fixedly installed at the bottom of the end of the L-shaped frame 3 away from the grinding table 1. A sliding assembly is connected to the inner side of the L-shaped frame 3 through a propulsion mechanism. A motor 5 is installed on the upper surface of the sliding assembly. A rotating shaft 37 is fixedly connected to the output end of the motor 5. A fixed shaft 16 is fixedly installed at one end of the rotating shaft 37 away from the motor 5, and a cross rod 20 is fixedly installed at the end of the fixed shaft 16. A ring seat 12 is sleeved on the outside of the cross rod 20, and annular grooves 18 are opened inside both sides of the ring seat 12. Two groups of grinding blocks 22 are symmetrically installed on the outside of the ring seat 12, and the number of grinding blocks 22 in each group is two. The two grinding blocks 22 are symmetrically arranged, and the front end faces and rear end faces of the two grinding blocks 22 are both provided with connecting components. The outer wall of the ring seat 12 is provided with multiple cleaning brushes 19.

[0027] The propulsion mechanism comprises a first hydraulic cylinder 6 fixedly mounted on the inner side of the L-shaped frame 3, and a telescopic end of the first hydraulic cylinder 6 is connected to the sliding assembly.

[0028] The sliding assembly includes a slide 11 slidably mounted on the outside of the L-shaped frame 3, one side of the slide 11 is connected to the telescopic end of the first hydraulic cylinder 6 through a fixedly mounted vertical plate 7, the motor 5 is fixedly mounted on the upper surface of the slide 11, an L-shaped rod 8 is fixedly connected to the upper outside of the vertical plate 7, the L-shaped rod 8 is rotatably matched with the rotating shaft 37, the first hydraulic cylinder 6 can drive the vertical plate 7 to telescope, causing the slide 11 and the motor 5 to approach the rectangular tube 2, allowing the motor 5 to drive the rotating shaft 37 to rotate automatically, causing the annular seat 12 on the outside of the rotating shaft 37 to rotate inside the rectangular tube 2.

[0029] The connecting assembly includes a sleeve rod 21 rotatably mounted on one side of the grinding block 22, a telescopic rod 28 is slidably mounted on the inner side of the sleeve rod 21, a positioning rod 25 is rotatably connected to the inner side of the telescopic rod 28 away from the sleeve rod 21, a running wheel 29 is fixedly mounted on one end of the positioning rod 25, the running wheel 29 is located on the inner side of the annular groove 18 and is rotatably matched with the inner wall of the annular groove 18, and the telescopic match between the telescopic rod 28 and the sleeve rod 21 can facilitate the adjustment of the grinding block 22, which is more convenient when the ring seat 12 and other components enter from one end of the rectangular tube 2;

[0030] When the ring seat 12 rotates, the positioning rod 25 and the running wheel 29 on the inner side of one end of the telescopic rod 28 can rotate in coordination inside the annular groove 18 .

[0031] Guide seats 26 are provided on the outside of the two sets of rods 21, and sliders 27 are slidably installed on the outside of the two guide seats 26. First push rods 17 are installed on the outside of the two sliders 27, and a clamping sleeve 24 is rotatably installed on the outside of the first push rod 17. A two-way telescopic rod 23 is commonly provided between the two clamping sleeves 24. The advancement of the two-way telescopic rod 23 can drive the clamping sleeve 24 to drive the corresponding slider 27 to move, thereby cooperating with the extension and contraction of the grinding block 22. At the same time, after the position of the grinding block 22 is established, the two-way telescopic rod 23 can ensure that the grinding block 22 is pressed against its respective position through its own tightening effect.

[0032] The end of the cross rod 20 away from the fixed axis 16 is connected to the vertical rod 30 through a rotatably installed support rod 38. The vertical rod 30 is used at one end through the support rod 38, so that components such as the positioning wheel 32 can provide supporting force at the front end of the ring seat 12. A battery 33 is installed on the outside of the vertical rod 30, a monitoring component is set at the top of the vertical rod 30, and a positioning wheel 32 is rotatably installed at the lower inside of the vertical rod 30.

[0033] The monitoring assembly includes a round seat 34 fixedly mounted on the top of the vertical pole 30, a frame 35 fixedly mounted on the outer side of the round seat 34, a camera 36 is arranged on one side of the frame 35, the camera 36 is electrically connected to the battery 33, a transparent window 31 is installed on the inner side of the frame 35, the model of the camera 36 is IP-GK03A, and when monitoring and recording, it is connected to the battery 33 wire, and the grinding condition can be observed at one end through the camera 36;

[0034] The transparent window 31 can prevent burrs and other impurities from splashing onto the mirror surface of the camera 36 during the grinding process.

[0035] The pipe clamping mechanism includes a fixed plate 14 fixedly installed on one side of the upper surface of the grinding table 1, a second hydraulic cylinder 9 is installed on the inner side of the fixed plate 14, a positioning frame 10 is fixedly installed on the telescopic end of the second hydraulic cylinder 9, connecting rods 15 are respectively extended from both ends of the outer side of the positioning frame 10, and sliding rods 13 are fixedly installed on the inner sides of the two connecting rods 15, and one end of the sliding rod 13 slides through the inner side of the grinding table 1. Under the telescopic drive of the second hydraulic cylinder 9, the corresponding positioning frame 10 can move toward the rectangular tube 2, so that one side of the positioning frame 10 is against the rectangular tube 2, and the rectangular tube 2 is arranged between the two positioning frames 10. When the positioning frame 10 moves, in order to ensure a smooth effect during movement, the two sliding rods 13 also slide and intersperse on the inner side of the grinding table 1.

[0036] Working principle: When in use, the rectangular tube 2 to be polished is first fixed on the top of the polishing table 1 through the tube clamping mechanism, and then the worker cooperates with the driving of the two-way telescopic rod 23 to let the sleeve rod 21 slide from the outside of the telescopic rod 28 and extend toward the corner of the rectangular tube 2, so that the polishing block 22 is positioned at the inner wall corner of the rectangular tube 2. The driving of the two-way telescopic rod 23 will drive the clamping sleeve 24 at one end to move, and the first push rod 17 inside the clamping sleeve 24 will drive the slider 27 to flexibly move on the outside of the guide seat 26 according to the position of the polishing block 22, thereby cooperating with the pressing work of the two-way telescopic rod 23, so that the two polishing blocks 22 can be at the inner corner of the corresponding rectangular tube 2. The ring seat 12 is kept in contact with the inner surface of the rectangular tube 2, and then as the propulsion mechanism and the sliding assembly reciprocate, the motor 5 drives the rotating shaft 37 and the fixed shaft 16 to rotate, so that the cleaning brush 19 on the outer side of the ring seat 12 rotates and grinds inside the rectangular tube 2. When the ring seat 12 rotates, the positioning rod 25 at the telescopic rod 28 enables the grinding block 22 to rotate with the ring seat 12 by setting a rotating matching running wheel 29 inside the annular groove 18. Therefore, the ring seat 12 drives the cleaning brush 19 to rotate and grind, and the grinding block 22 grinds the corner during the reciprocating movement. Finally, the grinding condition inside the rectangular tube 2 can be observed through the camera 36 above the vertical rod 30, thereby ensuring the grinding effect.
