[0002] The mine switch seal is a sealing element used in coal mine electrical equipment. It is mainly used to prevent leakage, moisture, dust and other problems in the operation of electrical equipment to ensure the normal operation and safety of the equipment. During the installation of the distribution point, the selection of the seal or the deviation of the inner diameter from the outer diameter of the cable can easily cause the electrical equipment to fail to explode. If the electrical equipment fails to explode, the flame generated inside the equipment will be transmitted to the outside of the shell and directly contact with the flammable and explosive gases underground, which will cause mine fires or coal dust explosions.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0022] like Figures 1 to 4 As shown, this embodiment discloses a sealing ring processing tool for mining electrical equipment, the processing tool comprises a fixing part 1, a cutter head part 2, and a positioning part 4; the cutter head part 2 and the positioning part 4 are both connected to the fixing part 1;

[0023] The fixing member 1 is arranged in a rectangular tube shape, and the blade member 2 is L-shaped. One end of the blade member 2 is inserted into the fixing member 1, and the outer diameter of the cross-section of the end head is adapted to the inner diameter of the cross-section of the fixing member 1 and the end head can slide in the fixing member 1 along the length direction of the fixing member 1 to adjust the position of the blade at the other end of the blade member 2. The other end of the blade member 2 is arranged in a blade shape and the end head is arranged downward;

[0024] The upper end surface of the cutter head 2 extending into the fixing member 1 is fixedly connected with a rubber layer 21 to increase its fixing friction; the top of the fixing member 1 is connected with a screwing member 3 for fixing the part of the cutter head 2 extending into the fixing member 1; the screwing member 3 is two screwing nuts arranged side by side, and the upper end of the fixing member 1 is provided with a screwing screw hole connected to the inside of the fixing member 1, and the bottom end of the screwing member 3 passes through the screwing screw hole and abuts against the rubber layer 21 on the upper end surface of the cutter head 2, and the outer wall of the screwing member 3 is threadedly connected with the screwing screw hole to realize the fixing operation of the cutter head 2;

[0025] A positioning stud 11 is fixedly connected to the bottom end of the fixing member 1 and is threadedly connected to the positioning member 4 through the positioning stud 11. The axial direction of the positioning stud 11 is consistent with the direction of the blade end of the cutter head member 2; the positioning member 4 is a cylindrical three-stage variable diameter structure, and the outer diameter of the axial end of the positioning member 4 gradually increases toward the other axial end of the positioning member 4, and its variable diameter position is set as an inclined guide surface, and its axial end edges are both chamfered structures; the axial end ends of the positioning member 4 are provided with positioning screw holes 41, and the positioning member 4 can be threadedly connected to the positioning stud 11 through the positioning screw holes 41.

[0026] When processing the sealing ring to be processed, first select a suitable positioning piece according to the inner diameter of the sealing ring to be processed, make the outer diameter of the positioning piece fit the inner diameter of the sealing ring, and then adjust the position of the cutter head to determine the cross-sectional radius of the cut sealing ring. After adjustment, fix the cutter head by screwing the screw, and finally control the fixing piece and the cutter head to rotate and cut;

[0027] When performing sealing ring cutting operations, both sealing rings with too large outer diameters and sealing rings with smaller inner diameters can be cut and processed; for example, the inner diameter of the sealing ring to be processed is 3 cm and the outer diameter is 10 cm; if a sealing ring with an inner diameter of 3 cm and an outer diameter of 7 cm needs to be processed, the locating piece with an outer diameter of 3 cm only needs to be inserted into the center hole of the sealing ring to be processed, and then the blade of the cutter head piece is adjusted to the position of the outer diameter of 7 cm of the sealing ring to be processed, and the desired sealing ring can be obtained by rotary cutting; for example, if the above-mentioned sealing ring to be processed needs to be processed into a sealing ring with an inner diameter of 5 cm and an outer diameter of 10 cm, the locating piece with an outer diameter of 3 cm is also inserted into the center hole of the sealing ring to be processed, and the blade of the cutter head piece is adjusted to the position of the outer diameter of 5 cm of the sealing ring to be processed, and the inner diameter of the sealing ring to be processed can be enlarged by rotary cutting to obtain the desired sealing ring; the entire device has a simple structure and can be applicable to a variety of sealing ring processing operations.

[0028] At the same time, when processing the sealing ring, a positioning piece with a suitable outer diameter can be selected according to the inner diameter of the sealing ring to be processed. In the present technical solution, by designing the positioning piece as a variable diameter structure and connecting it with the positioning stud through different positioning screw holes, positioning pieces with different outer diameters at the bottom end (such as Figure 1 , Figure 2 As shown in the figure, it is convenient for people to use; and when the inner diameter of some sealing rings is slightly small and difficult to install, the sealing ring can be put on the positioning piece variable diameter structure with a suitable outer diameter to expand the inner hole, which brings convenience to the installation of the sealing ring.

[0029] When the utility model is used, firstly, the relative position between the cutter head and the fixing part is adjusted, and the distance between the positioning part and the blade end of the cutter head is used as the cross-sectional size of the prepared sealing ring. Then, the positioning part is inserted into the central through hole of the sealing ring to be processed, and finally, the fixing part drives the cutter head to rotate, so that the blade of the cutter head performs annular cutting on the sealing ring to be processed, thereby obtaining a sealing ring that meets the requirements of electrical construction. It avoids the situation in which the sealing ring does not meet the size requirements and cannot be installed normally during the electrical construction process, ensures the normal progress of the electrical construction operation, effectively improves the operating efficiency of the electrical construction operation, and brings convenience to the electrical construction operation.
