Description
Technical Field
The utility model relates to a coal mine equipment, especially a sealing washer cutting device for coal mine switch.
Background
The sealing ring is widely applied in the use of coal mine electromechanical equipment, and plays an important role in explosion-proof safety performance, in the existing cutting technology, when a knife edge touches the sealing ring in the cutting process of the sealing ring, the sealing ring can be forced to shake by the knife edge because nothing is used for fixing the sealing ring, and therefore the sealing ring can not be cut to be neat and consistent in length and width. When the explosion-proof equipment is used, the sealing ring is needed to be used when the cable enters and exits the explosion-proof cavity. The inner diameter of the sealing ring is not matched with the outer diameter of the cable, the inner ring of the sealing ring is not flat, and the like, so that the sealing ring can not be normally used. Electricians commonly use paper cutters or self-made cutters to trim the inner ring of the sealing ring. The trimming amount is difficult to grasp, and excessive cutting amount, unevenness or burrs are difficult to avoid. The use is longer, also is difficult to repair perfect internal diameter circle (the bigger the sealing ring internal diameter is, the more difficult the cutting), cuts paper sword or self-control cutter often because of the difficult uneven of holding hard, easily injures skin, uses unsafe. Therefore, improvements and innovations in the sealing ring cutting apparatus are imperative.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming the defect of prior art, the utility model aims at providing a sealing washer cutting device for coal mine switch can effectively solve the difficult assurance of sealing washer cutting, and the quality is poor, uses unsafe, problem that work efficiency is low.
The utility model provides a technical scheme be, a sealing washer cutting device for colliery switch, including outer cover body, tool bit assembly body and cutting knife, tool bit assembly body one end embolias in outer cover body one end to fix on outer cover body by first screw and nut, the tool bit that stretches out outer cover body one end is equipped with tool bit assembly through-hole on the assembly body, and the blunt end of cutting knife inserts in the tool bit assembly through-hole, and by the second fix with screw on the tool bit assembly body, the dead lever is equipped with on one side of leaning on the tool bit assembly body on the outer cover body.
The utility model discloses simple structure, novel unique, easy manufacturing, convenient to use saves labour and saves time, and work efficiency is high, and is effectual, is the innovation on the sealing washer cutting knife, has apparent economy and social.

Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in the figures 1-4, the utility model relates to a sealing washer cutting device for coal mine switch, including outer cover body, tool bit assembly body and cutting knife, in tool bit assembly body 2 one end emboliaed outer cover body 1 one end to fix on outer cover body 1 by first screw 4 and nut 7, be equipped with tool bit assembly through-hole 2-2 on the tool bit assembly body 2 that stretches out outer cover body one end, the blunt end of cutting knife 3 inserts in tool bit assembly through-hole 2-2, and fixes on tool bit assembly body 2 by second screw 6, is equipped with dead lever 5 on the outer cover body 1 on one side by tool bit assembly body 2.
In order to ensure the using effect and the convenience in use, the outer sleeve body 1 is a hollow round made of metal, and a groove 1-1 (shown in figure 2) is formed in the inner surface of one end close to the fixing rod 5;
the cutter head assembly body 2 is made of metal and is circular, one side of the cutter head assembly body is provided with a cutter head assembly through hole 2-2 vertical to the axial direction, one end, close to the cutter head assembly through hole 2-2, is provided with a convex edge 2-1 matched with the groove 1-1, one end part of the cutter head assembly body 2 with the cutter head assembly through hole is a hollow body with an internal threaded hole, the internal threaded hole is communicated with the cutter head assembly through hole 2-2, and a second screw 6 is screwed in the internal threaded hole of the hollow body through external threads and is used for fixing a cutting knife 3 (shown in figure 4);
the cutting knife 3 is an integral structure consisting of a round cutter head (blunt part) at the upper part and a blade surface body (shown in figure 3) with the lower part connected with the cutter head;
the length of the outer sleeve body 1 is 0.23 meter, the length of the cutter head assembly body 2 is 0.12 meter, and the length of a blade surface body (a blade) is 81 mm;
the first screw 4 is M10X35, and the second screw 6 is M8X 45.
The utility model discloses during the use, according to cable external diameter cut the unnecessary interior layering of sealing washer, put into tool bit assembly body 2 perpendicularly with the tool bit, use screw in top tight, fixed, take out and treat the processing sealing washer, embolia dead lever 5 with the sealing washer hole, use screw in top tight, fixed, then put into outer cover 1 sleeve with tool bit assembly body 2 in, adjust tool bit assembly body 2 length, adjust to the external diameter size that needs, fasten outer cover 1 and go up the tight tool bit assembly body 2 in screw top. When in operation, one hand holds the sealing ring to stabilize the sealing ring and prevent the sealing ring from rotating; the outer sleeve of the device is held by the other hand, the cutter is driven to do circular motion by rotating the outer sleeve body, and the cutter rotates and moves relative to the fixed sealing ring, so that the sealing ring achieves the cutting purpose. The operation is carried out slowly, the cutting surface is ensured to be flat until the part of the outer diameter of the sealing ring is completely separated, the sealing rings with different outer diameter sizes are processed by adjusting the length of the inner sleeve in the outer sleeve, and the outer diameter size range of the processed sealing ring is 20-60 mm. The blade end keeps a certain thickness to form a plane, so that the sealing ring quick-cutting knife can have enough strength while the cutting function is realized, and the phenomenon that personnel are injured due to over sharp is avoided. The blade can be repeatedly polished at any time according to the abrasion condition.
