Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As shown in Figures 1-4, a PVC pipe inner wall polishing grinding head assembly includes a base 1. Two clamping blocks 2 are fixedly connected to the top of the base 1. Two bottom clamping rollers 3 are rotatably connected inside the two clamping blocks 2. Vertical blocks 4 are fixedly connected to the top of the two clamping blocks 2. First stepless hydraulic rods 5 are fixedly connected inside the two vertical blocks 4. Lifting blocks 6 are fixedly connected to the top of the two first stepless hydraulic rods 5. Extension blocks 7 are fixedly connected to the front of the two lifting blocks 6. The same top clamping roller 8 is rotatably connected inside the two extension blocks 7. A first motor 9 located to the right of the extension block 7 is fixedly connected to the right side of the top clamping roller 8. A grinding mechanism 10 is provided inside the base 1.

[0028] Vertical blocks 4 are slidably connected to the outer sides of the two lifting blocks 6, and PVC pipes 11 are provided on the inner sides of the two bottom clamping rollers 3 and the top clamping rollers 8.

[0029] The PVC pipe body 11 can be clamped and rotated by two bottom clamping rollers 3 and a top clamping roller 8.

[0030] The grinding mechanism 10 includes a second continuously variable hydraulic rod 101. A support block 102 is fixedly connected to the top of the second continuously variable hydraulic rod 101. Two load-bearing blocks 103 are fixedly connected to the top of the support block 102. Three pressure rollers 104 are rotatably connected to the opposite side of the two load-bearing blocks 103. A second motor 105 is fixedly connected inside one of the load-bearing blocks 103. A horizontal shaft 106 is fixedly connected to the output end of the second motor 105. A toothed block 107 is fixedly connected to the outside of the horizontal shaft 106. The toothed block 107 and the three pressure rollers 104 are provided with the same grinding rod 108. Several grinding blocks 109 are fixedly connected to the outside of the grinding rod 108.

[0031] The support block 102 can be finely adjusted by means of the second continuously variable hydraulic rod 101;

[0032] The grinding rod 108 has a number of tooth grooves 12 inside, and the tooth block 107 is adapted to the tooth grooves 12;

[0033] The grinding rod 108 can move left and right through the tooth block 107 and the tooth groove 12;

[0034] The grinding block 109 is located inside the PVC pipe body 11 and is adapted to the PVC pipe body 11.

[0035] The grinding block 109 allows the interior of the PVC pipe body 11 to be ground.

[0036] All three pressure rollers 104 are arranged in an arc shape, and the three pressure rollers 104 are adapted to the grinding rod 108;

[0037] The grinding rod 108 can move stably left and right through the three pressure rollers 104.

[0038] Working principle:

[0039] The PVC pipe body 11 is placed outside the two bottom clamping rollers 3. Then, the first continuously variable hydraulic rod 5 is activated, causing the lifting block 6 to descend. This, in turn, causes the lifting block 6 to move the extension block 7 and the top clamping roller 8 downwards, clamping the PVC pipe body 11 with the top clamping roller 8 and the two bottom clamping rollers 3. Next, the second continuously variable hydraulic rod 101 is activated, moving the support block 102 and adjusting the height of the two load-bearing blocks 103. The two load-bearing blocks 103 then move the three pressure rollers 104 and the toothed block 107 to adjust their height. Adjustment is made so that the grinding rod 108 can drive the grinding block 109 to be at the center of the PVC pipe body 11. The first motor 9 is started, and the output end of the first motor 9 drives the top clamping roller 8 to rotate, which in turn causes the top clamping roller 8 and the two bottom clamping rollers 3 to rotate the PVC pipe body 11. Then the second motor 105 is started, which drives the horizontal shaft 106 and the toothed block 107 to rotate, which in turn causes the grinding rod 108 to drive the grinding block 109 to move to the right, so that the grinding block 109 can grind the inside of the PVC pipe body 11.
