[0002] Bottom hole grinding shoes are a kind of drilling tools used in the process of oil well drilling and mining. They are mainly used for grinding and cleaning the well wall to ensure that the drill bit can drill smoothly. Grinding shoes are usually designed to have high hardness and wear resistance to adapt to the harsh working environment underground. In order to improve the wear resistance and service life of grinding shoes, grinding treatment is essential. Common grinding methods include mechanical grinding, manual grinding and chemical corrosion grinding. During the grinding process, it is necessary to ensure that the surface of the grinding shoes is smooth, free of burrs and scratches, so as to reduce the wear of the grinding shoes during drilling.
[0003] In traditional grinding devices for processing bottom well grinding shoes, most of them are put on the workbench and then grind the grinding shoes by a grinder. During the grinding process, the grinding shoes need to be fixed manually. Since the outer surface of the grinding shoes is mostly a relatively smooth curved surface, the grinding shoes are easy to move during grinding, resulting in grinding deviation, thus affecting the grinding effect of the grinding shoes.

[0024] Specifically, first, the output end of the cylinder 1 3 is used to drive the rack 5 to move inside the workbench 1, thereby driving the gear 4 to rotate inside the workbench 1, and then the rotation of the gear 4 drives the racks 5 on both sides to move synchronously, so that the movement of the two racks 5 drives the two fixed plates 2 to move relative to each other, and then the rear of the grinding shoe is fixed, and then the output end of the cylinder 2 7 drives the sleeve 8 to slide on the outer wall of the fixed column 13, thereby driving one end of the two connecting rods 9 to move up and down, and then the movement of the connecting rod 9 pulls the L-shaped rod 10 to rotate with the connection between the L-shaped rod 10 and the sliding plate 6 as the center of the circle, and the slide plate 11 is pushed to slide above the sliding plate 6 from the end that has not passed through the L-shaped rod 10, thereby driving the two clamping plates 12 to fix the front end of the grinding shoe, thereby achieving the effect of fixing the grinding shoe.
[0025] Reference Figure 4 The inner wall of the sliding plate 6 is fixedly connected with a spring 2 14 , the outer wall of the spring 2 14 is fixedly connected with a block 15 , the outer wall of the block 15 is slidably connected to the inside of the sliding plate 6 , and the outer wall of the block 15 is slidably connected to the inside of the workbench 1 .
[0026] Specifically, the sliding plate 6 slides on the inner wall of the workbench 1 so that the spring 2 14 pushes the block 15 to slide on the inner wall of the workbench 1, so that the block 15 can be pushed into the slot 20 set inside the workbench 1, achieving the effect of moving and fixing.
[0027] Reference Figure 4 The workbench 1 is slidably connected to a slide rod 16 inside, one end of the slide rod 16 is fixedly connected to a push plate 19, and the outer wall of the push plate 19 is slidably connected to the inside of the workbench 1. A plurality of slots 20 are opened inside the workbench 1.
[0028] Specifically, by driving the slide bar 16 , the push plate 19 is moved inside the workbench 1 , so that the card block 15 inside the card slot 20 can be pushed outward, thereby achieving the effect of driving the card block 15 .
[0029] Reference Figure 4 The outer wall of the push plate 19 is fixedly connected to a plurality of telescopic rods 17, the outer wall of the telescopic rods 17 is fixedly connected to the inside of the workbench 1, the outer wall of the push plate 19 is fixedly connected to a plurality of springs three 18, the outer wall of the spring three 18 is fixedly connected to the inside of the workbench 1.
[0030] Specifically, by moving the push plate 19 inside the workbench 1, the spring three 18 is stretched and rebounded between the push plate 19 and the workbench 1, and then the telescopic rod 17 guides the spring three 18 so that the spring three 18 can pull back the moved push plate 19, thereby facilitating the next use and achieving a rebound effect.
[0031] Working principle: When the grinding device for the bottom well grinding shoe is needed, first open the cylinder 1 3 inside the workbench 1, and drive the rack 5 to move through the output end of the cylinder 1 3, thereby driving the gear 4 to rotate, and then drive the rack 5 on the other side to move through the rotation of the gear 4, thereby driving the two fixed plates 2 to move relative to each other, and then fix the rear of the grinding shoe, and then press the slide bar 16, and drive the push plate 19 to move inside the workbench 1 through the movement of the slide bar 16, so that the block 15 inside the slot 20 is pushed back into the slide bar 16, so that the spring three 18 is stretched inside the workbench 1 and the push plate 19, and at the same time, the spring two 14 is contracted between the block 15 and the sliding plate 6, and then the sliding plate 6 is slid and the slide bar 16 is released. At this time The spring three 18 and the spring two 14 are no longer subjected to force to rebound. When the block 15 on one side of the sliding plate 6 moves to the side of the front slot 20, the block 15 is pushed to the inside of the slot 20 through the rebound of the spring two 14, so that the sliding plate 6 is adjusted and fixed, and then the distance between the sliding plate 6 and the fixed plate 2 is adjusted according to the size of the grinding shoe. After the adjustment is completed, the cylinder two 7 is turned on, and the output end of the cylinder two 7 drives the sliding sleeve 8 to slide on the outer wall of the fixed column 13, thereby driving one end of the two connecting rods 9 to move up and down, and then pushing the L-shaped rod 10 to rotate, and then the rotation of the L-shaped rod 10 drives the slide plate 11 to slide above the sliding plate 6, thereby driving the two clamping plates 12 to fix the front end of the grinding shoe, and then fixing the grinding shoe to facilitate the next step of grinding.
