Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Example 1: a ring cutting drill for plugging a pull rod hole is shown in figure 1 and comprises a drill barrel body 1 and a connecting portion 2, wherein the connecting portion 2 is used for installing a ring cutting drill bit and a ring cutting drill, the drill barrel body 1 comprises a first body 11 and a second body 12, at least one second body 12 is arranged, the second body 12 can be detachably fixed on the periphery of the first body 11, the inner periphery of the second body 12 is attached to the periphery of the first body 11, and a plurality of cutting teeth 121 are arranged on the periphery of the second body 12. The first body 11 is provided with a slag discharge groove 111 at the outer circumference thereof, and the extending direction of the slag discharge groove 111 is parallel to the axis of the first body 11.
Connecting portion 2 is used for the installation of ring cutting drill bit and ring cutting rig, and slag chute 111 is used for discharging the dirt bits of cutting, can dismantle fixedly through first body 11 and second body 12, can change second body 12 when cutting teeth 121 takes place wearing and tearing, need not whole change and bore a section of thick bamboo body 1, is guaranteeing the cutting performance of ring cutting drill bit, improves under the prerequisite of the cutting efficiency of ring cutting drill bit, has reduced construction cost.
As shown in fig. 1, the second body 12 is detachably fixed to the periphery of the first body 11, specifically, the first body 11 is provided with a threaded hole 112, the second body 12 is provided with a stepped hole 122, and the threaded hole 112 and the stepped hole 122 are provided with a locking bolt in a penetrating manner, so as to fix the second body 12 and the first body 11. Here, the depth of the outer stepped hole 122 is greater than the height of the head of the locking bolt, so that the head of the locking bolt can be embedded into the outer stepped hole 122 and kept lower than the surface of the second body 12, thereby avoiding the situation that the head of the locking bolt is worn down due to the contact of the locking bolt and a cutting body when the circular cutting drill is used for cutting, and the locking bolt loses the fastening effect.
As shown in fig. 2, in order to facilitate the installation between the second body 12 and the first body 11, a positioning assembly is disposed between the second body 12 and the first body 11, the positioning assembly includes a positioning pin 31 and a positioning hole 32, the positioning pin 31 and the second body 12 are integrally connected to each other at a side close to the first body 11, and the positioning hole 32 is opened at the periphery of the first body 11. Here, the positioning pins 31 may be uniformly arranged along the height direction of the second body 12, or may be staggered along the height direction of the second body 12. The positioning pin 31 can share the shearing force applied to the second body 12 when the cutting teeth 121 cut, so that the shearing force applied to the locking bolt is relatively reduced, the fastening function of the locking bolt is ensured, and the service life of the locking bolt is prolonged.
As shown in fig. 2, the first body 11 is extended with a pointed conical portion 4 at an end away from the connecting portion 2, so as to facilitate penetration of the circular cutting drill, the maximum diameter of the pointed conical portion 4 is equal to the outer diameter of the second body 12, and after the second body 12 is installed with the first body 11, the second body 12 is flush with the top of the pointed conical portion 4, so as to ensure the integrity of the circular cutting drill.
As shown in fig. 2, the connection portion 2 includes a first polish rod 21, a first threaded section 22 and a second polish rod 23, one end of the first polish rod 21 is fixedly connected to the center of the first body 11, the other end of the first polish rod is integrally connected to the first threaded section 22, the first threaded section 22 is threadedly connected to the reinforcing sleeve 5, one end of the first threaded section 22 away from the first polish rod 21 is integrally connected to the second polish rod 23, and one end of the second polish rod 23 away from the first threaded section 22 extends to form a second threaded section 231 for connecting the ring cutting drill. The thread direction of the first thread section 22 is opposite to the rotation direction of the connecting part 2, the thread direction of the second thread section 231 is opposite to the rotation direction of the connecting part 2, and when the circular cutting drill bit rotates, the connection between the reinforcing sleeve 5 and the first thread section 22 and the connection between the circular cutting drill bit and the circular cutting drilling machine are more tightly fixed.
As shown in fig. 1, the reinforcing sleeve 5 has an abutting surface 51 abutting against the first body 11, and the diameter of the abutting surface 51 is equal to the outer diameter of the second body 12. The abutting surface 51 is used for preventing the drill cylinder from shaking during the cutting process, and reducing the possibility of deformation of the joint of the first polished rod 21 and the first body 11.
Example 2: a trephine for plugging a pull rod hole is different from that of embodiment 1 in that as shown in fig. 3 and 4, a positioning assembly is arranged between a second body 12 and a first body 11 and comprises a positioning strip 33 and a positioning groove 34 which are matched with each other, the height of the positioning strip 33 and the height of the positioning groove 34 are equal to that of the first body 11, the positioning strip 33 and one side, close to the first body 11, of the second body 12 are integrally connected, and the positioning groove 34 is formed in the periphery of the first body 11. Here, the maximum diameter of the pointed tapered portion 4 is equal to the outer diameter of the second body 12, so that a protruding edge 41 is formed between the pointed tapered portion 4 and the first body 11, the lower end of the positioning bar 33 abuts against the protruding edge 41 when being mounted, the threaded hole 112 and the stepped hole 122 are positioned with the protruding edge 41 as a reference, and a locking bolt is inserted into the threaded hole 112 and the stepped hole 122 to fix the first body 11 and the second body 12. Compared with the positioning pin 31, the contact surface between the second body 12 and the first body 11 of the positioning strip 33 is increased, so that the positioning strip 33 can bear the shearing force applied to the second body 12 by the cutting teeth 121 during cutting to a greater extent, thereby relatively reducing the shearing force applied to the locking bolt, ensuring the fastening function of the locking bolt and prolonging the service life of the locking bolt.
Example 3: a tie rod hole plugging ring-cutting drilling machine comprises the tie rod hole plugging ring-cutting drill bit in the embodiment.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
