Abstract
The utility model discloses a multi-blade boring cutter. The boring cutter comprises a cutter head and a cutter handle, the front end of the cutter head is provided with a first cutting section, a second cutting section and a third cutting section in sequence, a groove is formed in the head portion of each cutting section, each blade is installed in each groove, a first cutting section groove is composed of an inner concave type face, two groove arms and fixing blocks which horizontally stretch out of the groove arms, and the inner concave type face, the two groove arms and the fixing blocks are integrally formed. The multi-blade boring cutter overcomes the shortages that each cutting section is provided with only one blade, processing speed is slow, the blades are fixed on the cutter head, and process is unstable in the prior art. The utility model provides the improved boring cutter. The multi-blade boring cutter can synchronously process a plurality of holes with different diameters and shortens process procedures, the blades can be stably controlled while the blades are processed and stressed, processing efficiency is improved, and time is saved.
Description
Technical field
The utility model belongs to the boring cutter cutter of machining, particularly a kind of multiple-cutting-edge boring cutter.
Background technology
In machining, the stepped hole that has is not only dark, and requires chamfering; The cutter heads that adopt many segment of cutting multi-tool edge in the prior art are installed a slice blade and are carried out hole processing more above every section segment of cutting; Though guaranteed axiality, but in the process, especially first segment of cutting, directly reaming on work piece, cutting output is big, require higher to blade, in working angles, two cutting edges of the first segment of cutting section are easy to because be subjected to force unbalance, cause the blade displacement, perhaps blade directly ruptures.
The utility model content
Technical problem to be solved in the utility model provides a kind of multiple-cutting-edge boring cutter, guarantees that blade can not be shifted in process.
In order to solve aforementioned technical problem, the utility model provides as the back technical scheme: a kind of multiple-cutting-edge boring cutter, comprise cutter head and handle of a knife, handle of a knife adopts Morse's cone, inside offers tapped through hole, described cutter head offers first segment of cutting, second segment of cutting, three segment of cutting successively, three sections segment of cutting adopt the coaxial staged of segmentation, the equal symmetry of the head of each segment of cutting has two grooves, and the described first segment of cutting groove is made up of integrated indent profile, two groove arms and a fixed block that crosses out the groove arm.
Further, the described fixed block distance that crosses out the groove arm is no more than 1/2nd of distance between the two groove arms.
Before the processing, install cutting blade and chamfered cutting edge successively as required earlier, then handle of a knife is connected with lathe, can process.
Advantage: the groove of first segment of cutting makes the fixing more stable of blade, and blade adds and can not be shifted man-hour, crosses out the fixed block of cell wall; played the effect of protection blade; make blade in cutting, be not easy to fracture, thereby prolonged the service life of blade.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the vertical view (one of them does not draw blade) of first segment of cutting of the present utility model.
Fig. 3 is the front view of the first segment of cutting groove of the present utility model.
Fig. 4 be the utility model specific embodiment 2 in the hole schematic diagram processed.
The specific embodiment
Example one
As Fig. 1, Fig. 2, shown in Figure 3, a kind of multiple-cutting-edge boring cutter, comprise cutter head 1 and handle of a knife 2, handle of a knife 2 adopts Morse's cone, inside offers tapped through hole 3, described cutter head 1 offers first segment of cutting 4, second segment of cutting 5, the 3rd segment of cutting 6 successively, described three sections segment of cutting adopt the coaxial staged of segmentation, the equal symmetry of the head of each segment of cutting has two grooves, in the described groove blade is installed, the described first segment of cutting groove is made up of indent profile 10, two groove arms 9 and a fixed block 11 that crosses out groove arm 9, and the described first segment of cutting groove is one-body molded.
The distance that described fixed block 11 crosses out groove arm 9 is no more than 1/2nd of distance between the two groove arms 9.
Before the processing, install cutting blade 8 and chamfered cutting edge 7 according to the processing needs, then handle of a knife is connected by bolt with lathe, can process.Wherein Fig. 1 is simplified painting, though only drawn two blades of first segment of cutting, second, third segment of cutting has all only been drawn a blade, and every section segment of cutting all can be installed two blades in concrete enforcement.
Example two
As Fig. 1, shown in Figure 4, be example with processing oil pump hole, need processing two sector holes altogether.Handle of a knife is installed on the boring machine, before processed oil pump spare is placed on workbench, start boring machine, first segment of cutting 4 of cutter head is stretched in the processed place of oil pump, slowly the feeding cutter hub processes blind hole 12, and roughing simultaneously goes out reaming 13, cutter head second segment of cutting 5 carries out fine finishining to reaming 13 again, and the chamfered cutting edge of cutter head the 3rd segment of cutting 6 is finished 45 ° of chamferings 14 in reaming 13 apertures simultaneously.
Described in the past only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; after the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. multiple-cutting-edge boring cutter, comprise cutter head and handle of a knife, handle of a knife adopts Morse's cone, inside offers tapped through hole, described cutter head offers first segment of cutting, second segment of cutting, the 3rd segment of cutting successively, and three sections segment of cutting adopt the coaxial staged of segmentation, and the equal symmetry of the head of each segment of cutting has two grooves, in the described groove blade is installed, it is characterized in that: the described first segment of cutting groove is made up of integrated indent profile, two groove arms and a fixed block that crosses out the groove arm.
2. multiple-cutting-edge boring cutter as claimed in claim 1 is characterized in that: the distance that described fixed block stretches out the groove arm is no more than 1/2nd of distance between the two groove arms.
