Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
For convenience of description, following embodiment, identical element represents with identical label.
Consult Fig. 4,5,6, the first embodiment that the utility model has the main shaft in built-in cooling spiral loop comprises an idler arm 2, cutter pawl 3, spindle axis 4, axle center water jacket 5, and four O type rings 6.
This idler arm 2 extends along an axis L and around this axis L pivotable, and can comprise first section 21 and second section 22 that arrange on the contrary along this axis L.
This cutter pawl 3 extends along this axis L, and has the first section 31 that connects the second section 22 of this idler arm 2, and second section 32 arranged along the first section 31 of this axis L this cutter pawl 3 contrary.
This spindle axis 4 is around this idler arm 2 and this cutter pawl 3, and delivery outlet 42, the spiral surrounding comprising parallel this axis L of input hole 41, four of four parallel this axis L in outer peripheral face and to should 43, four, cooling spiral loop, axle center arranging of idler arm 2 to the first section 21 of idler arm 2 should arrange and be communicated with first connecting hole 44 in described delivery outlet 42 and this cooling spiral loop, axle center 43, and four to the second section 22 of idler arm 2 should arrange and be communicated with second connecting hole 45 in described input hole 41 and this cooling spiral loop, axle center 43.
This axle center water jacket 5 is sheathed on this spindle axis 4, and around the outside in this cooling spiral loop, axle center 43.
A described O type ring 6 to be arranged between this axle center water jacket 5 and this spindle axis 4 and to lay respectively at two opposition sides in this cooling spiral loop, axle center 43 along this axis L.In the present embodiment, a described O type ring 6 is two opposition sides being arranged at this cooling spiral loop, axle center 43 in mode in pairs respectively.
During use, this idler arm 2 and this spindle axis 4 are driven and are driven this cutter pawl 3 and a cutter (not shown) being clamped by this cutter pawl 3 is rotated around this axis L, and then can machining be carried out, now, the flow direction (arrow see in Fig. 6) of cooling fluid (not shown) is sequentially by described second connecting hole 45 from described input hole 41, this cooling spiral loop, axle center 43 and described first connecting hole 44, finally exported by described delivery outlet 42, because cooling fluid is through this cooling spiral loop, axle center 43 constantly around this spindle axis 4, the distance of flowing is very long, and around the whole region of this idler arm 2, therefore, it is possible to significantly take away the heat that this idler arm 2 and this spindle axis 4 send, and then make this idler arm 2 can not temperature distortion and affect machining accuracy.
Be noted that, in other enforcement aspect, the quantity in cooling spiral loop, axle center 43 also can be multiple, it is such as four, and in parallel to each other spiral surrounding in the outer peripheral face of this spindle axis 4, each cooling spiral loop, axle center 43 is communicated with one of them corresponding first connecting hole 44 and one of them the second connecting hole 45 respectively, so also can reach radiating effect.
Consult Fig. 7,8,9, second embodiment of the present utility model is similar to this first embodiment, its difference be in:
Described input hole 41 extends to should the position of the second section 32 of cutter pawl 3, and described delivery outlet 42 extends to should the position of the first section 31 of cutter pawl 3.
This spindle axis 4 also comprise a spiral surrounding in outer peripheral face and to should the supplement heat rejecter helical loop 46, four that arranges of cutter pawl 3 to the first section 31 of cutter pawl 3 should arrange and be communicated with the 3rd connecting hole 47 of described delivery outlet 42 and this supplement heat rejecter helical loop 46, and four to the second section 32 of cutter pawl 3 should arrange and be communicated with the 4th connecting hole 48 of described input hole 41 and this supplement heat rejecter helical loop 46.
This second embodiment also comprises one and is sheathed on this spindle axis 4 and the auxiliary water jacket 7 in outside around this supplement heat rejecter helical loop 46, and two to be arranged between this auxiliary water jacket 7 and this spindle axis 4 and to lay respectively at the 2nd O type ring 8 of two opposition sides of this supplement heat rejecter helical loop 46 along this axis L.
So, this second embodiment also can reach the object identical with above-mentioned first embodiment and beneficial effect, and the flow direction of this cooling fluid (arrow see in Fig. 9) can also from described input hole 41 sequentially by described 4th connecting hole 48, this supplement heat rejecter helical loop 46 and described 3rd connecting hole 47, finally exported by described delivery outlet 42, significantly take away the heat that this cutter pawl 3 sends further, and then make this cutter pawl 3 also can not temperature distortion and affect machining accuracy.
Be noted that, in other enforcement aspect, the quantity of supplement heat rejecter helical loop 46 also can be multiple, it is such as four, and in parallel to each other spiral surrounding in the outer peripheral face of this spindle axis 4, each supplement heat rejecter helical loop 46 is communicated with one of them corresponding the 3rd connecting hole 47 and one of them the 4th connecting hole 48 respectively, so also can reach radiating effect.
In sum, by the setting in described input hole 41, described delivery outlet 42 and this cooling spiral loop, axle center 43, cooling fluid can take away heat through this cooling spiral loop, axle center 43, make this spindle axis 4 and this idler arm 2 can not temperature distortion and affect machining accuracy, cooling fluid compared to existing main shaft adopts the straight flow design directly gone out, the flow distance of cooling fluid of the present utility model is longer, therefore can take away heat by a larger margin, so really can reach the purpose of this utility model.
