Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.
Example 1
As shown in fig. 1-4, the round orifice burr remover of the present invention comprises a cutter head and a handle 3.
The shape of tool bit is the taper shape, and its middle position is equipped with rectangle opening 6 along vertical direction and divide into left tool bit 1 and right tool bit 2 with it, and left tool bit 1 and right tool bit 2 lie in the side with one side and are equipped with left cutting edge 4 and right cutting edge 5 respectively, and left cutting edge 4 and right cutting edge 5 are the contained angle of certain angle with its tangent line at the position on the tool bit to satisfy cutting orifice burr or the needs of remaining smear metal.
In this embodiment, the tool head portion is made of a material having good comprehensive mechanical properties such as formability and hardness, and the cutting edge portion is ensured to be sharp and durable (for example, high-quality tool steel) by a heat treatment method.
The handle 3 is in a V-shaped opening shape, the opening end of the handle is fixedly connected with the wide opening ends of the left tool bit 1 and the right tool bit 2 in a welding or bonding mode, and the left tool bit 1 and the right tool bit 2 can be opened and closed under the action of the V-shaped structure by pressing the handle 3 so as to meet the requirements of processing round orifices with different apertures; the cross section of the handle 3 is in the shape of a circular arc line, so that the surface of the handle 3 is in a curved surface structure to meet the requirement of ergonomics.
In addition, the inside cavity of cutter head sets up in this embodiment, forms circular conical groove 7, plays the effect of holding the bits when getting rid of the round hole mouth burr or remaining smear metal, and the smear metal that cuts down passes through rectangle opening 6 and gets into circular conical groove 7 in, avoids producing the influence to the orifice surface quality.
In the specific implementation of the embodiment, the handle 3 is pressed to close the left tool bit 1 and the right tool bit 2, the tool bit parts are deeply inserted into the proper positions of a round hole to be machined, the handle 3 is opened, the outer sides of the left tool bit 1 and the right tool bit 2 are abutted against the surface of the hole under the action of elastic force, then the handle 3 is rotated towards any direction, at the moment, the left cutting edge 4 or the right cutting edge 5 starts to cut burrs or residual cuttings of the round hole, the cut cuttings enter the conical groove 7 through the rectangular opening 6 and are discharged from the bottom of the conical groove, and the influence on the surface quality of the hole is avoided; after the burrs and residual cuttings in the round hole are removed, the left tool bit 1 and the right tool bit 2 are closed by pressing the handle 3, so that the size is reduced, and the tool bit is taken out of the round hole to finish machining.
Example 2
The difference between the present embodiment and embodiment 1 lies in that, four vertical sides of the two sides of the left tool bit 1 and the right tool bit 2 in the present embodiment are all provided with two cutting edges, wherein, the left cutting edge 4 is two, and the right cutting edge 5 is two, when removing the burr or the residual chip of the circular orifice, the rotating handle 3 can rotate in any direction, and one left cutting edge 4 and one right cutting edge 5 can work simultaneously, thereby greatly improving the removal efficiency of the burr or the residual chip of the circular orifice.
Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. All changes and modifications that may be made by the technical spirit of the present invention to the above embodiments by simple modification are considered to fall within the scope of the present invention.
