Background

The reamer is used for reaming the hole after the drilling process on the work piece, mainly is in order to improve the machining precision in hole, reduces the roughness on its surface, and the reamer on the existing market often can appear installing complicacy or appear installing unstability when installing in the in-process of being connected with the stick, consequently, we just provide a reamer of conveniently solving above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tungsten steel connects excellent reamer to solve the problem that the reamer installation on the existing market that above-mentioned background art provided is inconvenient and installation stability is not good.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a tungsten steel connects excellent reamer of yuan, includes tool bit, axostylus axostyle and yuan stick, the top installation of tool bit is provided with the axostylus axostyle to the outside fixed surface of axostylus axostyle has the external screw thread, the outside surface of axostylus axostyle is connected with the yuan stick through fastening bolt, and the fastening block is installed through the connecting axle in the outside of axostylus axostyle, and the outside of axostyl.

Preferably, the shaft rod is in threaded connection with the element rod, and a threaded hole is embedded in the outer portion of the shaft rod.

Preferably, the connecting shaft is arranged under the deflection shaft rod, the fastening blocks outside the connecting shaft are made of rubber, and the fastening blocks are distributed on the outside of the shaft rod at equal angles.

Preferably, the preformed groove before the surface of the shaft rod is inlaid is mutually clamped with the fastening block.

Compared with the prior art, the beneficial effects of the utility model are that: the tungsten steel connects the reamer setting of the round bar;

1. the whole reamer is mounted only through threaded connection and bolt connection, the whole connection work is very convenient, a large amount of time of workers is not consumed, and the dismounting and mounting work is convenient;

2. the setting of fastening block and torsional spring can be fine guarantees the stability of being connected between axostylus axostyle and the excellent under the effect of fastening block, and the phenomenon that the pine takes off can not appear easily takes place.

In the figure: 1. a cutter head; 2. a shaft lever; 3. a bar; 4. fastening a bolt; 5. a connecting shaft; 6. a fastening block; 7. a torsion spring; 8. and (4) external threads.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a tungsten steel connects excellent reamer of yuan, including tool bit 1, axostylus axostyle 2, yuan stick 3, fastening bolt 4, connecting axle 5, fastening block 6, torsional spring 7 and external screw thread 8, the top installation of tool bit 1 is provided with axostylus axostyle 2, and the outside fixed surface of axostylus axostyle 2 has external screw thread 8, the outside surface of axostylus axostyle 2 is connected with yuan stick 3 through fastening bolt 4, and the outside of axostylus axostyle 2 installs fastening block 6 through connecting axle 5, and the outside of axostylus axost.

Be threaded connection between axostylus axostyle 2 and the excellent 3, and the screw hole is inlayed to axostylus axostyle 2's outside, conveniently installs work.

Connecting axle 5 is partial to the below setting of axostylus axostyle 2, and its outside fastening block 6 is the rubber material to angular distribution such as fastening block 6 reaches the effect of guaranteeing the fastening nature of screw thread installation in the outside of axostylus axostyle 2, the convenient setting through fastening block 6's rotation fit torsional spring 7.

The preformed groove before the surface of the shaft lever 2 is embedded is mutually clamped with the fastening block 6, so that the clamping work of the fastening block 6 is facilitated.

The working principle is as follows: when the tungsten steel bar-connected reamer is used, firstly, a worker only needs to perform threaded connection between the outside of the shaft lever 2 and the inside of the bar 3, then, in the process of performing threaded connection, the whole shaft lever 2 can be rotated, when the shaft lever 2 is rotated inside the bar 3, the fastening block 6 outside the shaft lever 2 can be rotated and extruded under the action of the connecting shaft 5, and after the threaded connection between the whole shaft lever 2 and the bar 3 is completed, the fastening bolt 4 is used for mounting the upper parts of the bar 3 and the shaft lever 2, so that the whole mounting work is completed;

after the installation, since the fastening block 6 is located inside the element rod 3, the fastening block 6 can be reset by the torsion spring 7 and generate a compression inside the element rod 3, so as to ensure the stability of the threaded connection between the whole element rod 3 and the shaft rod 2.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
