Description
Technical Field
The utility model relates to the technical field of hole openers, in particular to a novel hole opener.
Background
The hole saw is also called a hole saw, and is classified into a carbon steel hole saw, a bimetal hole saw, a hard alloy (welding) hole saw and a diamond hole saw, wherein the bimetal hole saw is most widely used. Different types of hole saws are used for cutting different materials, and the difference of the production efficiency and the drilling quality of the surface of the processed material is caused in the using process due to the difference of the hole saw structure.
The bimetal hole digger is used as the most widely used hole saw, the tooth part is made of high-speed steel, the back material is made of chrome vanadium steel, the hardness of the tooth part can reach HRC63-68 by heat treatment and quenching, the tooth shape of the bimetal hole digger is milled or punched and formed, and then the tooth shape is divided into a sharp edge and a chip groove. The hole digger can drill metal, non-ferrous metal, wood, plastics and various artificial materials such as laminated board, medium density fiberboard, veneer (shaving) board, asbestos board, etc., and is widely applied to the building, maintenance and partial industrial manufacturing markets.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of a novel hole digger.
In order to solve the technical problems, the technical scheme provided by the utility model is a novel hole digger: the knife sharpening device comprises a connecting disc, an arc-shaped plate and knife sharpening assemblies, wherein the arc-shaped plate is distributed around the circumference of the connecting disc;
a through hole is formed in the circle center of the connecting disc;
the knife sharpening assembly comprises a first knife sharpening opening arranged on one side of the arc-shaped plate and a second knife sharpening opening arranged on the outer side wall of the arc-shaped plate; the second sharpening opening is far away from the first sharpening opening; one end of the bottom end of the second grinding edge is linearly increased towards the other end, and the lowest point is parallel to the bottom end of the first grinding edge and is close to the first grinding edge.
As an improvement, the connecting disc is provided with connecting holes distributed circumferentially around the through hole.
As an improvement, a groove is formed in the connecting position, close to the first grinding edge, of the connecting disc and the arc-shaped plate.
Compared with the prior art, the utility model has the advantages that: the utility model is used for the sedimentation and trimming of the down lamp or the spot lamp hole, and has convenient use, low manufacturing cost and good use effect.

As shown in the figure: 1. the grinding device comprises a connecting disc, 2, an arc-shaped plate, 3, a grinding edge assembly, 4, a through hole, 5, a first grinding edge, 6, a second grinding edge, 7, a connecting hole, 8 and a groove.
Detailed Description
The novel hole opener of the present invention is further described in detail below with reference to the accompanying drawings.
With reference to the attached drawings 1-3, the novel hole digger comprises a connecting disc 1, an arc-shaped plate 2 distributed around the circumference of the connecting disc 1 and a grinding knife edge assembly 3 arranged on the arc-shaped plate 2;
the center of the connecting disc 1 is provided with a through hole 4;
the knife edge assembly 3 comprises a first knife edge 5 arranged on one side of the arc-shaped plate 2 and a second knife edge 6 arranged on the outer side wall of the arc-shaped plate 2; the second mill knife edge 6 is far away from the first mill knife edge 5; one end of the bottom end of the second grinding edge 6 is linearly increased towards the other end, and the lowest point is parallel to the bottom end of the first grinding edge 5 and is close to the first grinding edge 5.
And connecting holes 7 distributed circumferentially are formed on the connecting disc 1 around the through hole 4.
And a groove 8 is formed at the joint of the connecting disc 1 and the arc-shaped plate 2 close to the first mill knife edge 5.
The specific implementation process of the novel hole digger is as follows: the device penetrates through an external rotating shaft by using a through hole 4 in the connecting disc 1, and simultaneously penetrates through a connecting hole 7 by using a stud to be fixed on the rotating shaft, so that the rotating shaft rotates to drive the connecting disc 1 and the arc-shaped plate 2, and the grinding edge assembly 3 on the arc-shaped plate 2 performs settlement and trimming work.
The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the utility model as defined by the appended claims.
