AI Technical Summary
During the roll processing process, due to the high hardness of the roll, the drill bit is prone to slip and offset and fall off when drilling, and lacks protection devices, poses a safety risk, and the falling drill bit may continue to idle and cause harm to the operator or others.
A special drill tool for roll processing is designed, including drill bit, shell, connecting rod, rotating disc, linkage block and spring. Through the spring's elastic release mechanism, when the drill bit is offset and slides down, the connecting rod and drill bit are away and the insertion plate is inserted. The slot of the linkage block prevents the drill bit from rotating.
It effectively prevents the drill bit from idling, reduces safety risks, and ensures the safety of operators.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller processing, in particular to a special drill tool for roller processing. Background Art
[0002] The types and manufacturing processes of rolling mill rolls have been continuously developed with the advancement of metallurgical technology and the evolution of steel rolling equipment. Rolls are mainly composed of a roll body, a roll neck and a shaft head. During the production and processing of rolling mill rolls, holes and grooves need to be drilled and grooved on the roll body to facilitate the connection between the shaft head and the roll body. A drilling machine is usually used to drill holes in the roll body.
[0003] When drilling holes in the roller body, due to the high hardness of the roller itself, the drill bit is prone to slip and deflect when drilling holes in the slot and fall off the roller surface. After the drill bit falls off, there is no protective device installed and the drill bit will continue to rotate. The idling drill bit may cause harm to others, posing a safety risk.
[0004] Therefore, we propose a special drill tool for roller processing to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a special drill tool for roller processing to solve the problems raised in the above background technology.
[0006] To achieve the above object, the utility model provides the following technical solutions: a special drill tool for roller processing, comprising a drill bit and a shell sleeve rotatably connected to the drill bit, a connecting rod is provided above the drill bit, and a moving opening adapted to the connecting rod is opened on the top of the shell sleeve;
[0007] The top of the drill bit is fixedly connected with a first rotating disk, the bottom of the connecting rod is fixedly connected with a second rotating disk, the bottom of the connecting rod is fixedly connected with a linkage block, and the top of the drill bit is fixedly connected with a plug plate.
[0008] Preferably, a plurality of pairs of evenly distributed springs are fixedly connected between the second rotating disk and the first rotating disk.
[0009] Preferably, a slot is provided at the bottom of the linkage block, and the slot is adapted to the plug board.
[0010] Preferably, the linkage block is vertically perpendicular to the top of the plug board.
[0011] Preferably, a bearing ring is fixedly connected to the surface of the drill bit, and the drill bit is rotatably connected to the shell sleeve through the bearing ring.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] When the drill bit deviates and slides off the surface of the roller, the multiple groups of springs arranged between the first rotating disk and the second rotating disk release their elasticity, pushing the connecting rod and the drill bit away from each other, and the plug plate is inserted into the slot opened on the surface of the linkage block, so that the connecting rod cannot rotate with the drill bit, thereby ensuring that the drill bit will not idle and cause harm to the operator or others.

[0018] 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 The utility model provides a technical solution: a special drill tool for roller processing, including a drill bit 1 and a shell sleeve 2 rotatably connected to the drill bit 1. When in use, it is installed with a drilling rig through a connecting rod 3. After the connecting rod 3 is installed with the drilling rig, the installation of the drill bit 1 and the shell sleeve 2 is also completed.
[0020] For details, please refer to Figure 1-3 When drilling, the drill bit 1 squeezes the roller. While the drill bit 1 squeezes the roller, the connecting rod 3 is affected by the reverse force and presses the second rotating disk 6 and the linkage block 7 to move downward. When the linkage block 7 moves downward, the plug plate 8 fixedly connected to the top of the first rotating disk 5 is inserted into the slot 10 opened on the surface of the linkage block 7. At this time, the drill bit 1 is locked with the connecting rod 3 through the plug plate 8 and the linkage block 7, and the drill bit 1 is driven to rotate through the connecting rod 3. The drill bit 1 is ensured by the bearing ring 11 to be not affected by the shell 2 during rotation, thereby realizing the drilling operation.
[0021] For details, please refer to Figure 1-3When the drill bit 1 deviates and slides off the surface of the roller, the multiple groups of springs 9 arranged between the first rotating disk 5 and the second rotating disk 6 release their elasticity, pushing the connecting rod 3 and the drill bit 1 away from each other, and the plug plate 8 is inserted into the slot 10 opened on the surface of the linkage block 7, so that the connecting rod 3 cannot rotate with the drill bit 1, thereby ensuring that the drill bit 1 will not idle and cause harm to the operator or others.
[0022] Working principle: when in use, it is installed with the drilling rig through the connecting rod 3. After the connecting rod 3 and the drilling rig are installed, the installation of the drill bit 1 and the shell 2 is also completed. When drilling, the drill bit 1 squeezes the roller. While the drill bit 1 squeezes the roller, the connecting rod 3 is affected by the reverse force to press the second rotating disk 6 and the linkage block 7 to move downward. When the linkage block 7 moves downward, the plug plate 8 fixedly connected to the top of the first rotating disk 5 is inserted into the slot 10 opened on the surface of the linkage block 7. At this time, the drill bit 1 is locked with the connecting rod 3 through the plug plate 8 and the linkage block 7, and the drill bit 1 is driven to rotate through the connecting rod 3. The drill bit 1 is guaranteed not to be affected by the shell 2 during rotation through the bearing ring 11, thereby realizing the drilling operation. When the drill bit 1 deviates and slides off the surface of the roller, the multiple groups of springs 9 arranged between the first rotating disk 5 and the second rotating disk 6 release their elasticity, pushing the connecting rod 3 and the drill bit 1 away from each other, and the end plug plate 8 is inserted into the slot 10 opened on the surface of the linkage block 7, so that the connecting rod 3 cannot rotate with the drill bit 1, thereby ensuring that the drill bit 1 will not rotate idly and cause harm to the operator or others. This solves the problem that when drilling holes in the roller body, the drill bit 1 is prone to slipping and deviating when drilling holes in the slot due to the high hardness of the roller itself, and thus falls off from the surface of the roller. After the drill bit 1 falls off, there is a lack of installed protective devices, and the drill bit 1 will continue to rotate. The idling drill bit 1 may cause harm to others, posing a safety risk.
