Following detailed description of the invention will be entered a step in conjunction with above-mentioned accompanying drawing and the utility model will be described.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, when an assembly is considered to " connection " another assembly, it can be directly connected to another assembly or may there is the assembly arranged placed in the middle simultaneously.When an assembly is considered to " being arranged on " another assembly, it can be set directly on another assembly or may exist simultaneously the assembly arranged placed in the middle.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in description of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Please refer to Fig. 1 to Fig. 4, the collet chuck hilt 100 of the utility model embodiment, comprises tool rest 10, elastic collet chuck 30 and nut 50.Tool rest 10 is threaded with nut 50, and elastic collet chuck 30 is arranged between nut 50 and tool rest 10.Elastic collet chuck 30 is for holding cutter 200, and under coordinate of tool rest 10 with nut 50, elastic collet chuck 30 produces elastic deformation, thus clamp-on tool 200, clamped cutter can be, but not limited to as milling cutter, drill, lathe tool etc.
Tool rest 10 can be used for the main shaft connecting board, so that under the drive of motion of main shaft, drives the cutter 200 on tool rest 10 to move together.One end of tool rest 10 offers accepting hole 11 along its axis direction, in order to partial receipt elastic collet chuck 30.One end that tool rest 10 is provided with accepting hole 11 forms external thread part 13, for coordinating with nut 50.
Elastic collet chuck 30 inner hollow, it comprises first end 32 and second end 33 relative with first end 32, and elastic collet chuck 30 offers the accommodation hole 31 of through first end 32 and the second end 33 in the axial direction, in order to accommodate and to clamp cutter 200.Elastic collet chuck 30 comprises the first tapered wall 36 and the second tapered wall 37.Contiguous second end 33 of contiguous first end 32, second tapered wall 37 of first tapered wall 36, and the length being shorter in length than this second tapered wall 37 of this first tapered wall 36.First tapered wall 36 of elastic collet chuck 30 is connected by a cannelure 35 with between the second tapered wall 37, and cannelure 35 forms catch surface 351(as Fig. 3 near the side of first end 32).In the present embodiment, catch surface 351 is annular, and with the axes normal of elastic collet chuck 30.First tapered wall 36 and the second tapered wall 37 longitudinally offer some bar shaped groovings 34, and part grooving 34 extends to first end 32, and part grooving 34 extends to the second end 33.The length of described grooving 34 is less than the length of this elastic collet chuck 30, to make elastic collet chuck 30 radial contraction can occur when being subject to external force, thus causing accommodation hole 31 to diminish, forcing elastic collet chuck 30 clamp-on tool 200.
Nut 50 offers pilot hole 51, shoulder hole 52 and bellmouth 58 successively along its central axis 101 from one end.This shoulder hole 52 is between this pilot hole 51 and this bellmouth 58.One end of this pilot hole 51 this nut 50 through, its inwall is formed internal thread part 57, in order to be threaded with the external thread part 13 of tool rest 10.This bellmouth 58 is positioned at this nut 50 one end away from internal thread part 57, in order to match with the first tapered wall 36 of elastic collet chuck 30.
Please refer to Fig. 5 and Fig. 6, the madial wall of this shoulder hole 52 is extended with holding section 59 towards central axis 101, described holding section 59 is for holding with the catch surface 351 of elastic collet chuck 30.The intersection of this holding section 59 between the larger hole and less hole of this shoulder hole 52.In the present embodiment, this holding section 59 comprises two first protruding 53 and second projection 55 that interval protrudes out formation.Two first projections 53 and second projection 55 are in order to hold with catch surface 351, and two first projections 53 and second projection 55 are housed in cannelure 35.The shape of two the first projections 53 is similar, and two the first projections 53 respectively to the angle between the vertical join line of central axis 101 be acute angle.
In the present embodiment, each first projection 53 comprises one near the arc-shaped side 531 of central axis 101, and arc-shaped side 531 is less than the outer radius (outward flange of catch surface 351 as Fig. 6 dotted line illustrated) of catch surface 351 to the beeline of central axis 101.Second projection 55 comprises one near the straight flange 551 of central axis 101, and straight flange 551 is less than the outer radius of catch surface 351 to the beeline of central axis 101, and therefore, catch surface 351 can be held in the first protruding 53 and second projection 55.Straight flange 551 is recessed to form inner concave arc surface 553, the bottommost of inner concave arc surface 553 is substantially equal to the outer radius L2 of catch surface 351 to the vertical range L1 of central axis 101.
Please refer to Fig. 4 and Fig. 7, during assembling, first elastic collet chuck 30 is loaded in nut 50.When elastic collet chuck 30 is loaded nut 50, can be tilted the central axis 101 of relative for elastic collet chuck 30 nut 50 certain angle, and avoid two the first projections 53, first tapered wall 36 of elastic collet chuck 30 is snapped in from straight flange 551, now, first tapered wall 36 is fitted with bellmouth 58, and catch surface 351 is stuck in two first projections 53 and the second projection 55.Then, the first end 32 of cutter 200 from elastic collet chuck 30 is inserted accommodation hole 31.Finally, inserted in the pilot hole 51 of nut 50 by tool rest 10, and external thread part 13 screws togather with the internal thread part 57 of nut 50, now, the second tapered wall 37 of elastic collet chuck 30 fits with the accepting hole 11 of tool rest 10.
When disassembling, rotary nut 50, cutter 200 is taken out from elastic collet chuck 30, continue rotary nut 50 together to take off from tool rest 10 to by the nut be assembled together 50 and elastic collet chuck 30, then the first tapered wall 36 is pressed near straight flange 551 from the first end 32 of elastic collet chuck 30, one end of elastic collet chuck 30 is first removed hold, then elastic collet chuck 30 is taken out from nut 50.
Collet chuck hilt 100 in present embodiment, because catch surface 351 is held in two first protruding 53 and second projection 55, in cutter operation, balance is better.In assembling and unloading process, to load or to unload elastic collet chuck 30 more simple and convenient, and in this process, reduce the wearing and tearing to elastic collet chuck 30.In addition, in unloading process, when nut 50 is separated with tool rest 10, elastic collet chuck 30 together can be taken out of, avoid elastic collet chuck 30 to stay in tool rest 10.
Be appreciated that in other embodiments, this holding section 59 can comprise two or more first projection 53.
Be appreciated that in other embodiments, this holding section 59 can comprise two or more the second projections 55.
In addition, those skilled in the art also can do other change in the utility model spirit, and certainly, these changes done according to the utility model spirit, all should be included in the utility model scope required for protection.
