Technical Field

[0001] This utility model relates to the field of screw drill technology, specifically a grinding and clamping fixture for mine screw drills. Background Technology

[0002] A screw drill is a type of downhole power drill that uses drilling fluid as its power source and converts liquid pressure energy into mechanical energy. After prolonged use, screw drills need to be polished. During the polishing process, the screw drill needs to be clamped and fixed to ensure the quality of the polishing.

[0003] Most existing grinding clamping fixtures for screw drills only clamp and fix one end of the screw drill, resulting in poor stability and making effective grinding difficult.

[0004] To address the aforementioned problems, this utility model provides a grinding and clamping fixture for mine screw drill bits. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding and clamping fixture for mine screw drills, which can quickly and effectively clamp mine screw drills stably and facilitate effective grinding, thereby solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding and clamping fixture for mine screw drills, comprising a rectangular frame, a sliding plate fixedly mounted at the bottom center of the rectangular frame, a lead screw mounted inside the sliding plate, a first motor mounted at the end of the lead screw, T-shaped plates symmetrically arranged on both sides inside the rectangular frame, a bidirectional threaded lead screw passing through the lower end of the two T-shaped plates, a second motor mounted at the end of the bidirectional threaded lead screw, rotatable rotating columns symmetrically arranged inside the two T-shaped plates, circular grooves for fixing the mine screw drills symmetrically opened on the opposite sides of the rotating columns, a third motor mounted at the upper end of one of the T-shaped plates, the third motor driving the corresponding rotating column to rotate, and studs mounted inside the sidewall of the circular groove.

[0007] Furthermore, a lead screw and a guide rod are respectively provided on both sides inside the skateboard. The guide rod is symmetrically fixed with a base at both ends. The lead screw is threadedly connected to the inside of the skateboard, and the guide rod is slidably connected to the inside of the skateboard. The first motor is fixedly installed on the outer wall of the corresponding base, and its output end extends and is fixedly connected to the end of the lead screw. The outer side of the lead screw away from the first motor is rotatably connected to the inside of the side wall of the corresponding base through a bearing.

[0008] Furthermore, the bidirectional threaded screw is internally threaded to the lower end of the T-shaped plates on both sides, and the outer side of the lower end of the T-shaped plates is slidably connected to the inner side of the rectangular frame. The second motor is fixedly installed on the outer side of the end of the rectangular frame, and its output end extends and is fixedly connected to the end of the bidirectional threaded screw. The outer side of the bidirectional threaded screw away from the second motor is rotatably connected to the inner side wall of the rectangular frame through a bearing.

[0009] Furthermore, the third motor is fixedly mounted on the upper surface of the T-shaped plate and a gear is fixedly mounted on the output end. A gear ring is fixedly provided on the outer side of the rotating column corresponding to the third motor away from the circular groove. The gear ring meshes with the gear. The outer sides of both rotating columns are rotatably connected to the inside of the corresponding T-shaped plate through bearings.

[0010] Furthermore, protrusions are fixed on the outer sides of the opposite ends of the rotating columns on both sides.

[0011] Furthermore, omnidirectional wheels are fixedly installed on both sides of the bottom of the base, so that the upper structure does not interfere with the base when the skateboard is in motion.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides a grinding and clamping fixture for mine screw drills. The mine screw drill is placed horizontally with one end inserted into a corresponding circular groove. A second motor drives a bidirectional threaded screw to rotate, causing T-shaped plates on both sides to move synchronously in opposite directions. This, in turn, causes rotating columns on both sides to move synchronously in opposite directions, inserting the other end of the mine screw drill into the corresponding circular groove for initial fixation. Then, the studs on both sides are manually rotated to further fix the mine screw drill, forming a unified structure with the rotating columns. A third motor then drives the corresponding rotating columns to rotate, thereby rotating the mine screw drill for easy grinding. During grinding, a first motor drives the screw to rotate, causing a rectangular frame to reciprocate horizontally, which in turn causes the rotating mine screw drill to reciprocate horizontally, further facilitating grinding. The purpose of this design is to quickly and effectively clamp the mine screw drill stud ... Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] To solve the technical problem of how to effectively clamp the material for easy polishing, such as... Figure 1-4 As shown, the following preferred technical solutions are provided:

[0021] A grinding and clamping fixture for mine screw drills includes a rectangular frame 7. A sliding plate 6 is fixed at the bottom center of the rectangular frame 7. A lead screw 2 is installed inside the sliding plate 6. A first motor 4 is installed at the end of the lead screw 2. T-shaped plates 10 are symmetrically arranged on both sides inside the rectangular frame 7. A bidirectional threaded lead screw 8 is inserted through the lower end of the two T-shaped plates 10. A second motor 9 is installed at the end of the bidirectional threaded lead screw 8. Rotatable rotating columns 11 are symmetrically arranged inside the two T-shaped plates 10. Circular grooves 12 for fixing the mine screw drill are symmetrically opened on the opposite sides of the rotating columns 11. A third motor 18 is installed at the upper end of one of the T-shaped plates 10. The third motor 18 can drive the corresponding rotating column 11 to rotate. A stud 14 is installed in the side wall of the circular groove 12.

[0022] Specifically, the mine screw drill bit is placed horizontally with one end inserted into the corresponding circular groove 12. Then, the second motor 9 drives the bidirectional threaded screw 8 to rotate, causing the T-plates 10 on both sides to move synchronously in opposite directions, which in turn causes the rotating columns 11 on both sides to move synchronously in opposite directions, allowing the other end of the mine screw drill bit to be inserted into the corresponding circular groove 12, thus initially fixing the mine screw drill bit. Next, the studs 14 on both sides are manually rotated to further fix the mine screw drill bit, making it a unified unit with the rotating columns 11 on both sides. Then, the third motor 18 drives the corresponding rotating column 11 to rotate, thereby driving the mine screw drill bit to rotate for easy grinding. During grinding, the first motor 4 drives the screw 2 to rotate, causing the rectangular frame 7 to move horizontally in a reciprocating linear motion, which in turn causes the rotating mine screw drill bit to move horizontally in a reciprocating linear motion, further facilitating grinding. The purpose of this design is to quickly and effectively clamp the mine screw drill bit stably and to facilitate effective grinding.

[0023] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0024] Screw 2 and guide rod 3 are respectively provided on both sides inside the slide plate 6. Base 1 is symmetrically fixed at both ends of the guide rod 3. Screw 2 is threadedly connected to the inside of the slide plate 6, and guide rod 3 is slidably connected to the inside of the slide plate 6. The first motor 4 is fixedly installed on the outer wall of the corresponding base 1 and its output end extends and is fixedly connected to the end of the screw 2. The outer side of the screw 2 away from the first motor 4 is rotatably connected to the inside of the side wall of the corresponding base 1 through a bearing. The purpose of this design is that the first motor 4 drives the screw 2 to rotate, thereby driving the slide plate 6 to reciprocate linearly in the horizontal direction.

[0025] Furthermore, such as Figure 1 and Figure 3 As shown, the following preferred technical solutions are provided:

[0026] The bidirectional threaded screw 8 is internally threaded to the lower end of the two T-shaped plates 10. The outer side of the lower end of the T-shaped plate 10 is slidably connected to the inner side of the rectangular frame 7. The second motor 9 is fixedly installed on the outer side of the end of the rectangular frame 7, and its output end extends and is fixedly connected to the end of the bidirectional threaded screw 8. The outer side of the bidirectional threaded screw 8 away from the second motor 9 is rotatably connected to the side wall of the rectangular frame 7 through a bearing. The purpose of this design is that the second motor 9 drives the bidirectional threaded screw 8 to rotate, thereby causing the two T-shaped plates 10 to move horizontally in a linear synchronous direction or move away from each other.

[0027] Furthermore, such as Figure 1-3 As shown, the following preferred technical solutions are provided:

[0028] The third motor 18 is fixedly installed on the upper surface of the T-shaped plate 10, and a gear 17 is fixedly installed at the output end. A gear ring 16 is fixedly provided on the outer side of the rotating column 11 corresponding to the third motor 18 away from the circular groove 12. The gear ring 16 meshes with the gear 17. The outer sides of the rotating columns 11 on both sides are rotatably connected to the interior of the corresponding T-shaped plate 10 through bearings. The purpose of this design is to ensure that the rotating columns 11 on both sides can rotate. The third motor 18 drives the gear 17 to rotate, and through meshing with the gear ring 16, drives the corresponding rotating column 11 to rotate.

[0029] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0030] Both sides of the rotating column 11 have protrusions 13 fixed on their opposite outer sides. The stud 14 is threadedly connected to the threaded hole in the center of the protrusion 13 and extends into the circular groove 12. The outer end face of the stud 14 is fixed with a handle 15. The inner end face of the stud 14 is attached with an anti-slip pad. The two ends of the mine screw drill tool are engaged with the inner side of the circular groove 12. The purpose of this design is to drive the stud 14 to rotate through the handle 15, push the anti-slip pad to squeeze the outer side of the mine screw drill tool, and further fix the mine screw drill tool.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0032] Both sides of the bottom of the base 1 are fixedly installed with casters 5. When the skateboard 6 moves, the upper structure does not interfere with the base 1. The purpose of this design is to facilitate the movement and fixation of the base 1 through the casters 5, while ensuring the rationality of the structure.

[0033] In summary: The mine screw drill bit is placed horizontally with one end inserted into the corresponding circular groove 12. Then, the second motor 9 drives the bidirectional threaded screw 8 to rotate, causing the T-plates 10 on both sides to move synchronously in opposite directions. This, in turn, causes the rotating columns 11 on both sides to move synchronously in opposite directions, allowing the other end of the mine screw drill bit to be inserted into the corresponding circular groove 12, thus initially fixing the mine screw drill bit. Next, the studs 14 on both sides are manually rotated to further fix the mine screw drill bit, forming a unified whole with the rotating columns 11 on both sides. Then, the third motor 18 drives the corresponding rotating column 11 to rotate, thereby driving the mine screw drill bit to rotate for easy grinding. During grinding, the first motor 4 drives the screw 2 to rotate, causing the rectangular frame 7 to move horizontally in a reciprocating linear motion, which in turn drives the rotating mine screw drill bit to move horizontally in a reciprocating linear motion, further facilitating grinding. The purpose of this design is to quickly and effectively clamp the mine screw drill bit stably and to facilitate effective grinding.
