New description: [New technical field] This creation relates to a collet, especially a tool collet with an outlet structure that increases the efficiency of coolant discharge by the arrangement of the gutter. [Prior Art] Please refer to the fifth and sixth figures. The figure shows an existing collet, which is a δ and a collet body (40). The collet body (4〇) is cylindrical. An outer end surface (4 1 ) and an inner end surface (4 2 ) are formed on both end faces, and a ring groove (43) is recessed at an outer periphery close to the outer end surface (4 1 ), the groove (43) and the outer end surface The surface between the (4 1 ) and the inner end surface (4 2 ) is the inclined surface of the outer end; the collet body (40) is provided with a cutter hole (4 4 ) at the axial center, and A plurality of mutually spaced slots (45) are disposed between the outer end surface (4 1 ) and the inner end from (4 2 ) around the tool central hole (4 4 ), and each of the slots (45) is obliquely disposed. And an opening is formed in the outer periphery of the cutter hole (4 4 ) and the collet body (4 〇), and each of the just-arranged 45 and #cutt (4 5 ) which are arranged around the opposite end is relatively tight without the grain body (4) 〇) - so that each f (45) does not cause the collet to be unusable due to the gap between the outer circumference of the collimator m (4 〇) and the knives (4 4 ). (4~— Knowing that the inner end of the body (4 0) is the same as the inner end of the holder (5 〇), the inner circumference of the shank (5 且) is fitted with the inner circumference of the nut (52): , M318481 screw the nut (52) into the free end of the cutter bar (5〇), so that the collet body "〇 can be screwed toward the tapered groove (51), and the same has a flow path (") The cutter (60) is inserted into the cutter hole and the towel, and then the nut (52) is screwed to the cutter bar (50) and squeezed by the nut (52) and the tapered groove (51). Make the tool hole (44) / pa, /, (6 〇), and because of the collet body (4 hard grooving (45), the cylinder loss can achieve a large radial deformation, so it is better The cool effect of the existing collet, although the grooving of each of the collets "5) will still be === liquid: but the coolant is mainly cooled by the flow of the cutter (6〇) =—" Use, so when the tool hole is used (4 1 未 position without the tool of the flow path, the grooving (4 5 ) is two out, but the liquid removal τ is not concentrated on the tool, the water output is also better ^ Therefore, the efficiency of cooling is low, and there is a change to a gentleman. [New content] ^The need to improve this shortcoming. Since the existing tool collet is inserted in combination with the tool without the flow path, there will be a disadvantage that the tool is not concentrated and the waste is not easily removed. The purpose of this creation is to solve the technical problem that the above-mentioned coolant is difficult to concentrate the tool out and the waste is difficult to be removed, so that the above-mentioned purpose provides a technical problem. The knife with the effluent structure is::: is provided with a collet body, the main body of the tube is formed on both ends of the surface, and the surface is "face", and the end of the phase (four) is surrounded by the groove '(4) m knife, _^ ^ M318481 The inner end face is surrounded by a plurality of mutually spaced outer cuts: the inner end face is surrounded by the outer end face and is provided with a complex: externally cut groove 'characterized by: mutually spaced inner cutters" The peripheral wall of the peripheral wall opens rearward with a water outlet groove between adjacent outer slits, and each of the water outlets is located at the rear end and communicates with the front end of the corresponding inner slit. The small and the larger and further, the material Located adjacent to the peripheral wall of the tool holder hole The water sump between the grooving grooves is preferably one of the lower ones, and the inner surface of each of the water sumpes is formed in the middle of the inner surface of the water sump - the bottom surface of each of the gully grooves is a slanting surface having a rear end shallower than the front end. _ surface, preferably, each gully Before and after the depth—the heart end forms a shallower outlet. I Gray cutting is used in the tapered groove of the arbor when the creation is used, and the nut is fitted into the groove and then screwed. Lock the front end of the arbor, and at the same time, identify the side of the arbor and the tool, and then screw the nut to the arbor. The nut is tightly clamped by the nut and the tapered groove to fit the inner and outer slots. The beam design allows the tool holder hole to be tightened and the tool is positioned. When the coolant is injected into the rear end of the body of the collet, the coolant will flow into the gutters from the inner trough of the corresponding gutter [by each water outlet] The design of the small two in front of the ditch 'sprays the coolant forward' and because the drain is next to the inserted tool, the coolant flowing out is concentrated for the use of the cooling tool. Creation can provide the function of cooling the tool without the runner, and improve the cold Efficiency and to increase the flow rate to strengthen the waste out of the genus. M318481 [Embodiment] For a tool collet having a water discharge structure, refer to the preferred embodiment of the first to third figures, which is provided with: a body (10) 'collector body (1〇) system a cylindrical shape and an outer end surface (1 1 ) and a front end portion of a meat mountain two weeks surround the concave-circular concave: Π;;) 2) 'collar body (1 〇) Wear a 3 at the outer end of the shaft (1 ".../hole (1 4 ), and (14)-#-, 1 2 ) around the tool holder hole (1 two equally spaced outer cuts) The groove (15), each circumscribed) the end face (Η), the cutter hole (i 4 ) of the steam and the body of the core body (the outer peripheral wall of the ... forms an opening, 乂 2 5) whose axial length is shorter than the tube The body of the clip (")·cut... The same clip body (1 ◦) and six outer equally spaced inner slits (16) are arranged around the outer end surface (11) of each outer slit (1 end). 14) On the inner end face (12) Knife 曰 (16) (1 〇) outer peripheral wall m = pinhole (1 4 circumference wall and collet body length is shorter than the collet core 22 incision groove (") (4) To the tool hole (1 / open two back) The peripheral wall of each of the two) is formed by the outer end surface (11) ("), the bottom surface of the water outlet groove (171) between each water discharge groove (15), and the middle surface of the inner surface of the water drain groove is formed into a concave groove. The shallow bevel is used to: the surface (171) has a rear end depth that is closer to the front end, and each of the spouts = the size of the groove (17) forms a rear end of the front small, large, and upper 7) and respectively corresponds to the corresponding inscribed groove. M318481 (1 6 ) is connected to jr, thereby guiding the coolant from the corresponding inner slit (16). The number of inner slits (16) and outer slits (丄5) in a preferred embodiment In addition to the above six, other number of settings may be made, and the water drain (1 7 ) may be provided only one, or may be provided with more than two settings, and the present invention is not limited thereto. When using, please refer to the second and third figures, with the inner end face (1 2 ) - the end plug is placed in the tapered groove (2 丄) of the shank (2 〇), and the screw head (2 2 ) is used. After the inner circumference is folded into the groove (丄3), screw the screw head (2 2 ) into the free end of the knife bar (2 〇), and insert the tool (3 〇) into the tool holder? L ( 1 4) in, of course Screw the screw (2 2 ) to the cutter bar (20), and press II with the nut (2 2) and the tapered groove (2 work) to fit the inner slits (丄5) & The retractable design of the outer cutting groove (丄6) allows the tool holder hole (1 4 ) to tighten the blade (3 〇) and position it. S When the coolant is injected from the rear end of the collet body (1 〇) The coolant will flow into the respective drains (1 7 ) from the corresponding drains (1 7 )# inner cuts (丄6), and the coolant will be designed by the front small and large drains (i 7 ). The front discharge function, because the water outlet (1 7) white knitting opening is adjacent to the tool lost hole (1 4 ) and adjacent to the inserted tool (3 〇), the outflowing cold liquid will be concentrated for cooling tool use. And the flow is also sufficient to increase the efficiency of the cooling tool (3 〇). - Monthly signing of the second preferred embodiment of the fourth figure, which changes the shape of the gutter (17) in the first preferred embodiment.
