Abstract
For processing a cutter for sidewise hole, comprise drill bit, described drill bit end is provided with the cutter head with cutting blade, described cutter head by being connected to handle of a knife by mechanical axis, also comprise can be enclosed within described by mechanical axis and with the countersunk head drill bit of its synchronous axial system.The utility model has following beneficial effect: in the processing for concave shape workpiece, take drill bit and the countersunk head drill bit of this auxiliary type, achieve a set of multiplex functional, simple to operate in running, two cutters are used but not need again to remove and install, positioning precision is high, the through hole be up to and the axiality of counterbore large.
Description
Technical field
The utility model relates to mechanical processing technique technical field, particularly a kind of cutter for processing sidewise hole.
Background technology
When machined part, some factory needs the part of the concave shape processing inner band counterbore, and counterbore needs in the two ends of concave shape, to survey perforate, because the distance between concave shape part is too little, be difficult to implement common counterbore step, cutter can not well vertically enter.
Owing to market having demand to produce this part, therefore existing technology has following several.
One, be that cutter is tilted an angle, the angled cutter of band slowly deeply needed out the face of heavy mouth, hole, this is that precision prescribed is very not high, and when must have out a counterbore, and also can not produce in batches, very big to the wearing and tearing of cutter.
Two, be when mould molding, block the counterbore needing to open with special plunger, after injection mo(u)lding, special plunger is pounded out, the length sum that now should meet two Gent plungers must be less than the width of the notch of concave shape part, just can make its smooth depanning.
Three, be directly beaten counterbore according to common counterbore technique on the concave shape part of half, then with welding or types screw fixation technique, part half of for script two is fixed together, the cost compare of this technology is high, and the technique of impact entirety is attractive in appearance.
Summary of the invention
For deficiency of the prior art, the utility model provides a kind of cutter for processing sidewise hole, solves existing processing difficulties, the problem that cost is high.
The utility model is achieved through the following technical solutions.
For processing a cutter for sidewise hole, comprise drill bit, described drill bit end is provided with the cutter head with cutting blade, described cutter head by being connected to handle of a knife by mechanical axis, also comprise can be enclosed within described by mechanical axis and with the countersunk head drill bit of its synchronous axial system.Supporting cutter, makes it use without the need to dismantling again, has saved the time of workman, and production cost.
As preferably, countersunk head drill bit internal is offered porose, and described can coordinating with hole by mechanical axis makes countersunk head bit, and described cutter head and the maximum outside diameter by mechanical axis are less than the diameter of handle of a knife, and the junction by mechanical axis and handle of a knife is stepped.Cross section by mechanical axis can be less than to equal the polygon of 8 or the cross section of band stress point, and ladder place can effectively have good positioning the position of countersunk head drill bit.
As preferably, described countersunk head drill bit outer setting has cutting blade.For getting counterbore and excretion waste material.
Compared with prior art: in the processing for concave shape workpiece, take drill bit and the countersunk head drill bit of this auxiliary type, achieve a set of multiplex functional, simple to operate in running, two cutters are used but not need again to remove and install, positioning precision is high, the through hole be up to and the axiality of counterbore large.

Fig. 2 is the side view of countersunk head drill bit of the present utility model.
Fig. 3 is the structural representation of drill bit of the present utility model.
Fig. 4 is the structural representation of concave shape workpiece of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further.
A kind of cutter for processing sidewise hole, comprise drill bit 2, described drill bit 2 end is provided with the cutter head 23 with cutting blade, described cutter head 23 is by being connected to handle of a knife 21 by mechanical axis 22, also comprise can be enclosed within described by mechanical axis 22 and with the countersunk head drill bit 1 of its synchronous axial system, countersunk head drill bit 1 inside offers porose 11, described can coordinating with hole 11 by mechanical axis 22 makes countersunk head drill bit 1 rotate, described cutter head 23 and be less than the diameter of handle of a knife 21 by the maximum outside diameter of mechanical axis 22, stepped with the junction of handle of a knife 21 by mechanical axis 22, described countersunk head drill bit 1 outer setting has cutting blade.
Coordinate the use of cutter, not only remain the original function of drill bit, more add the function of countersunk head drill bit, same lathe operates, eliminate the time of dismounting cutter, and axiality is improved greatly, save production cost.
For a kind of method for processing sidewise hole, process according to following steps.
1) after concave shape workpiece 3 side direction is fixing, draw upper anchor point, open lathe with scoring tool, drill bit 2 starts to rotate, and slowly punches whole concave shape workpiece after aiming at anchor point with drill bit 2, forms through hole 32.
2) after through hole 32 is formed, slowly promote the notch 33 upper middle place of drill bit 2 to concave shape workpiece 3, with hand, the endoporus 11 of countersunk head drill bit 1 being aimed at drill bit 2 puts to multidiameter place from bottom to up, multidiameter place can effectively have good positioning the position of countersunk head drill bit 1, opens lathe, slowly rotary drill bit 2 under a more slow-revving state, it is made to rotate together, be increased to the rotating speed wanted, according to the depth requirements set, get counterbore 34.
3) when having beaten counterbore 34, untiing the concave shape workpiece 3 fixed, making its integrated overturn 180 degree, needing out the perforated surfaces of symmetrical counterbore 31 to rotate extremely, again fixing concave shape workpiece (3) and repeating above-mentioned step 2, getting counterbore 31.
The complete concave shape workpiece 3 for subtend counterbore that needs just completes.Next concave shape workpiece 3 can repeat the step of above-mentioned 1 to 3.
Protection domain of the present utility model includes but not limited to above embodiment; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection domain of the present utility model.
