The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1,2,3, the cooled hilt 10 of the applicable different size cutter that the utility model embodiment 1 is provided includes: a knife bar 12, an elastic collet chuck 14, a roller bearing 16, a lock nut 18, a socket nut 20, some Joint for water supply 22 and a locating ring 24; Wherein:

This knife bar 12 has a fit portion 25 and an axis hole 26; Fit portion 25 is the end section that is positioned at knife bar 12, and axis hole 26 is top, bottom center through knife bar 12, and hole wall be provided with that several is provided with vertically draw ditch 28, it is terminal and extend to knife bar 12 bottom surfaces respectively to draw ditch 28.

This elastic collet chuck 14 is to be straight-tube shape, and stack shell has some vertical profile grooves 32; This collet chuck 14 is located at the axis hole 26 of knife bar 12 with respect to fit portion 25 positions, and with its sheathed cutter 30 in bottom, makes cutter 30 extend outward from the bottom surface of knife bar 12 central authorities.

This roller bearing 16 is to be loop shaped, is sheathed on fit portion 25 outsides of knife bar 12, because roller bearing 16 is the habitual element of industry, therefore repeats no more.

This lock nut 18 is that spiral shell is located at this roller bearing 16 outsides, in order to order about collet chuck 14 clamp-on tools 30 indirectly.

This socket nut 20 has a centre bore 34, be embedded with a seal ring 36 on the hole wall of centre bore 34, and centre bore 34 is provided with some holes 38 that connect on every side, respectively connect hole 38 and be circular hole ground from socket nut 20 bottom surfaces to being recessed on, and have one day centre bore 34 directions in the top through the through hole 40 of socket nut 20; Socket nut 20 is to be screwed together in lock nut 18 bottoms, and is positioned at outside, knife bar 12 bottom, makes cutter 30 be arranged in the centre bore 34 of socket nut 20.

Respectively this Joint for water supply 22 is to include a sleeve pipe 42, a ball 44 and a spring 46; Each sleeve pipe 22 bottom has ring-type retaining wall 48, and ball 44 has a perforation 50, be to be located in the sleeve pipe 42 and to be resisted against to keep off wall 48 inboards, and spring 46 is to be located in the sleeve pipe 42; Each Joint for water supply 22 is solid and be embedded in respectively the connecing in the hole 38 of socket nut 20 tightly with sleeve pipe 42 plug, making ball 44 be limited to spring 46 connects in the hole 38, spring 46 1 ends contact at and connect hole 38 inner faces, and the other end then pushes against ball 44 and is connected on the retaining wall 48; As shown in Figure 3, in conjunction with after sleeve pipe 42 front ends concordant with socket nut 20 bottom surfaces, and perforation 50 is the axis hole 26 that ditch 28 is communicated in knife bar 12 that draws via the profile groove 32 of through hole 25 and elastic collet chuck 14 and knife bar 12; The user can utilize an aid to intert in the perforation 50 of ball 44, uses to adjust ball 44 and turn to, and then changes the direction of perforation 50.

This locating ring 24 is discoideus, and its external diameter is identical with centre bore 34 apertures of socket nut 20, locating ring 24 tools one endoporus 35, and the hole wall of endoporus 35 is embedded with a seal ring 52; This locating ring 24 is to be located in the centre bore 34 of socket nut 20, make that cutter 30 is to be arranged in endoporus 35,52 of seal rings closely are located on around the cutter 30, and owing to perisporium outside the locating ring 24 is squeezed in seal ring 36, forms locating ring 24 and be anchored on the socket nut 20.

More than be each member of the utility model and the explanation of relevant position thereof, as shown in Figure 1, this roller bearing 16 is in advance in conjunction with advance nut 18 inside, and as shown in Figure 2, when hilt 10 during in conjunction with cutter 30, cooling fluid can be injected into knife bar 12 inside from axis hole 26 top ends of knife bar 12, and be subjected to due to the obstruct of cutter 30 and seal ring 36 grades, cooling fluid will followed the profile groove 32 of collet chuck 14, the drawing ditch 28 of knife bar 12 inside and flowing toward each Joint for water supply 22 direction, and enter in the sleeve pipe 42 by through hole 40, from perforation 50 ejections of ball 44, the cooling-lubricant that is sprayed will directly produce cooling and lubricant effect to cutter 30 and machined object position (not shown) again.

When user's desire is changed the cutter of another different-diameter, be only need change the outfit to be suitable for the collet chuck of new cutter, and interior hole dimension cooperate the locating ring of new tool diameter to get final product; By this, the utility model can be more under the prerequisite of changing knife rod, lock nut and socket nut, is suitable for the cutter of various differences cun, reduces the purpose that is suitable for cost to reach.

Needs in the visual use of the utility model in addition, with Joint for water supply with other multi-form replacements; See also Fig. 4, be the utility model embodiment 2, the main member of itself and embodiment 1 is roughly the same, characteristics are: the sleeve pipe 62 bottoms system of the Joint for water supply 61 of hilt 60 protrudes from the bottom surface of socket nut 63, use and make things convenient for the user to change Joint for water supply 61, or as shown in Figure 5, be the utility model embodiment 3, when the user must the conducting cooling fluid or is only needed to connect hole ejection cooling fluid by part, connecing of socket nut 71 can be changed in the hole 72 and establish a plug and establish part 73, in order to the cooling liquid flowing channel in the sealing hilt 70, make the cutter ejection of cooling fluid via a tool central through hole, use cooling cutter and machining object.
