The utility model belongs to the technical field of cutting element, refers to especially a kind ofly can change cutter head and the high target drills cutter of intensity.
Background technology
Existing target drills cutter 50 as shown in Figure 4 comprises hilt body 51 and most cutter heads 52 that are embedded on the hilt body 51 of a hollow, wherein, hilt body 51 centers are provided with one and pay attention to hole 510, the annular periphery wall of hilt body 51 is provided with leading of several inclination and cuts groove 511, two adjacent leading are cut and are formed a protruding seat 512 between the groove 511, be provided with one in the same side of each protruding seat 512 and cut the V-arrangement cutter groove 513 that groove 511 communicates with leading, in each cutter groove 513, establish a described cutter head 52 respectively, each cutter head 52 and place spiral shell by a bolt respectively and be located in the cutter groove 513.
Add man-hour, can form a macropore by cutter head 52 drilling on thin plate; Can also be as shown in Figure 5 form an annular groove 61 in workpiece 60 surperficial drillings, and a cylinder 62 that stretches in the hole 510 carefully, so-called " paying attention to " drilling formed.
Yet, because the cutter head 52 of existing target drills cutter is that direct spiral shell is located on the hilt body 51, and in the process of drilling, if metal is cut bad as if chip removal, will be accumulated in annular groove 61 inside, cause leading of contiguous cutter groove 513 to cut groove 511 perisporiums and wear and tear even burst apart, situation promptly can't bear to use once burst apart, need to change whole hilt body 51, therefore, its proportion of goods damageds height, cost height.
Therefore, the structure of Xian You target drills cutter has necessity of further improvement.
The utility model content
In order to improve above-mentioned shortcoming, main purpose of the present utility model is to provide a kind of target drills cutter of changing the hilt body, reducing cost of not needing.
Based on above-mentioned purpose, major technique means provided by the utility model comprise:
One hilt body, for having the cylinder of two ends, two ends are made as a cutting end, a handle end respectively, be provided with an axially recessed carefully hole in the center, cutting end, be interval with most chip areas on the annular perisporium of hilt body, form a protruding seat between the two adjacent chip areas, be respectively equipped with the tool tip groove in the same side of each protruding seat, this tool tip groove communicates with cutting end and chip area;
Most tool tip are to be installed in each tool tip groove with removable shape coupling, and tool tip is provided with a recessed cutter groove and towards a side of chip area and is located at screw in the cutter groove;
A most cutter head are to be installed in each cutter groove with removable shape coupling;
Bolt more than one is placed through the screw that cutter head and spiral shell are located at tool tip respectively.
Preferable, described protruding seat is provided with the perforation that is communicated with two chip areas one or more, and tool tip is provided with screw coaxial with perforation respectively more than, and other establishes the bolt more than, and it is placed through protruding perforation respectively and spiral shell is located at the screw of tool tip.
Preferable, the tool tip groove of described target drills cutter is provided with the acute angle end slot that goes out towards the handle distal process from protruding seat perisporium, and the profile of tool tip and this acute angle end slot mate and be concavo-convex and cooperate.
Preferable, described target drills cutter is provided with a recessed caulking groove in the contiguous face of paying attention to the hole of tool tip groove, and this caulking groove is communicated with the cutting end; The profile of described tool tip is concavo-convex with the caulking groove coupling and cooperates.
Preferable, the tool tip groove of described target drills cutter has two kinds of different depths, and two adjacent tool tip groove depth differences.
Implement after the above-mentioned technological means, the obtainable concrete beneficial effect of the utility model is:
Because cutter head is to see through tool tip to be fixed on the hilt body, therefore, when causing the tool tip wearing and tearing in the working angles because metal fillings blocks even bursting apart, as long as change this tool tip, do not need to change whole hilt body, to reach the purpose that reduces cost.
Thus, tool tip is subjected to axially and blocking effect radially, makes tool tip when cutting, be unlikely to displacement, to guarantee cutting quality.
Thus, cutter head can be positioned on the different-diameter after installing, and when therefore cutting, the cutting position of workpiece can be divided into the cutter head cutting by two diverse locations, therefore, can reduce the burden of cutter head, reduces the tool bit abrasion rate, and improves stock-removing efficiency.
