Background technology
General purpose tool machine is to utilize relative motion between cutter and workpiece to complete the cutting operation of workpiece, wherein for example, with regard to rotating cutting tool (abrasive wheel or drill bit), cutter is normally installed on a hilt, and then hilt is installed on to one of toolroom machine main shaft, so can transfer to drive hilt and cutter jointly to rotate by the high-speed rotary of main shaft, to reach cutting effect.
Yet, cutter can have multiple different form because of the needs of processing operation, but the structural design of hilt can only be installed the cutter of single form at present, that is a hilt can only be installed a kind of cutter, so certainly will must produce multiple multi-form hilt, could and cutter between collocation mutually, therefore, in prior art, the structure of hilt can cause the increase in operational trouble and manufacturing cost and have necessity of improvement.
Summary of the invention
The utility model technical issues that need to address have been to provide a kind of hilt that multi-form cutter can be installed, and are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: have one first cutter fixed part and one second cutter fixed part; This first cutter fixed part has a breasting face and at least one location division of being located at this breasting face; This second cutter fixed part has a central shaft hole.
Compared with prior art, the beneficial effects of the utility model are: due to two kinds of multi-form cutters can be installed, for user, select, can promote working (machining) efficiency, increase operation ease, and reduce manufacturing cost.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
The main purpose of the utility model is to provide a kind of hilt, and it can be installed two kinds of multi-form cutters and select for user, to promote working (machining) efficiency, to increase operation ease, and reduces manufacturing cost.
In order to reach above-mentioned purpose, the hilt of the utility model includes a cutter fixed part and one second cutter fixed part, this the first cutter fixed part has the location division that a breasting face and at least two is located at this breasting face, in order to one abrasive wheel is fixed on to this breasting face through being located at respectively one of this location division bolt, this the second cutter fixed part has a central shaft hole, uses and wears fixing for a drill bit; Thus, user can select this abrasive wheel or this drill bit to process a workpiece according to actual needs.
In the embodiment of the utility model, the breasting face of this first cutter fixed part is rounded, and, this the second cutter fixed part connects the breasting face of this first cutter fixed part and extends towards the direction away from this first cutter fixed part along an axis with its one end, this axis is by the center of circle of this breasting face, among this second cutter fixed part arbor hole from the other end of this second cutter fixed part the direction along this axis towards this first cutter fixed part extend.User can install this abrasive wheel or this drill bit along same set direction, to increase operational convenience.
Refer to Fig. 1 and Fig. 2, the hilt 10 of the utility model comprises one first cutter fixed part 11 and one second cutter fixed part 12.The first cutter fixed part 11 has a breasting face 13, the shape of breasting face 13 can be various geometries, wherein take circle as optimal selection, and, breasting face 13 is provided with four location divisions 14, each location division 14 of this preferred embodiment is to take screw as example, (as long as in fact at least two), and those location divisions 14 are centered by the center of circle of breasting face 13 and arrange in mode in pairs; The second cutter fixed part 12 connects the breasting face 13 of the first cutter fixed part 11 and extends towards the direction away from the first cutter fixed part 11 along an axis A with its one end one, axis A can be by the center of circle of breasting face 13, in addition, the second cutter fixed part 12 has a central shaft hole 15, central shaft hole 15 from the other end of the second cutter fixed part 12 direction along axis A towards the first cutter fixed part 11 extend.On the other hand, hilt 10 has more an installation portion 16, installation portion 16 extends away from the direction one of the first cutter fixed part 11 back to one of breasting face 13 side along axis A court from the first cutter fixed part 11, in order to hilt 10 is installed on a main shaft (not shown).
When actual assembled, as shown in Figure 3, Figure 4, after user can select that an abrasive wheel 20 is sheathed on to the second cutter fixed part 12, be resisted against again the breasting face 13 of the first cutter fixed part 11, then by four bolts 30, pass respectively one of abrasive wheel 20 perforation 22 and be locked in the location division 14 of the first cutter fixed part 11, in order to abrasive wheel 20 is fixed on to the first cutter fixed part 11, abrasive wheel 20 now can carry out grinding operation to workpiece along with the rotation of hilt 10.In addition as shown in Figure 5, user also can select a drill bit 30 to wear and be fixed among the second cutter fixed part 12 in arbor hole 15, makes drill bit 30 to workpiece, carry out bore operation along with the rotation of hilt 10.
To sum up institute is old, the hilt 10 of the utility model can be installed two kinds of multi-form rotating cutting tools, not only can improve the problem of prior art hilt and effectively reduce manufacturing cost, can allow in use user select wherein a kind of rotating cutting tool to install according to process requirements, even also above-mentioned two kinds of rotating cutting tools (that is abrasive wheel 20 and drill bit 40) can be fixed on simultaneously to first, second cutter fixed part 11,12(of hilt 10 as shown in Figure 6), to save the time of dismounting cutter in process, reach the effect that promotes working (machining) efficiency.
