Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As Fig. 1, 2, shown in 7, a kind of cutting machine cutter locking device provided in present embodiment, comprise cutter 1 and cutter holder 21, described cutter 1 outer wall sleeve includes a pair projection 9, described cutter holder 21 comprises turnbarrel 22, locking device 23, turnbarrel 22 inwall is provided with a pair groove 24, cutter stretches into from cutter holder turnbarrel 22 upper end, through cutter holder turnbarrel 22, cutter 1 outer wall sleeve upper protruding block 9 embedded rotating sleeve 22 inwall upper groove 24, cutter holder turnbarrel 22 lower end is exposed in cutter 1 lower end with blade, turnbarrel 22 upper end is connected with locking device 23, locking device 23 forms compression fit by contacting with projection 9 upper surface on cutter outer wall sleeve, turnbarrel 22 outer wall is provided with gear tooth 30 and is connected with motor by belt 31.
As shown in Fig. 3,4,5 further, described locking device 23 comprises centring ring 25, locking nut 26, turnbarrel 22 upper surface positioning runner 27, described centring ring comprises alignment pin 28, centring ring groove 29, alignment pin 28 coordinates with turnbarrel 22 upper surface positioning runner 27, make the initial position of centring ring groove 29, turnbarrel inwall upper groove 24 consistent, locking nut 26 is with bolts with centring ring.Described turnbarrel upper surface positioning runner 27, for axle and at the one section of circular groove formed along turnbarrel upper surface with turnbarrel center, such frame mode makes locking nut 26, centring ring 25, turnbarrel 22 be combined as a whole, Cutting tool installation manner initialized location is alignd, so that mounting cutter by positioning runner 27.During mounting cutter, first locking nut 26 is screwed to initial position, even if centring ring groove 29, turnbarrel inwall upper groove 24, on same straight line, cutter 1 is inserted from cutter holder upper end, successively through locking nut 26, centring ring 25, turnbarrel 22, by the projection 9 direction adjustment on cutter outer wall sleeve to entering centring ring groove 29 and turnbarrel inwall upper groove 24, press down cutter, by the projection 9 embedded rotating sleeve lining upper groove 24 on cutter outer wall sleeve, tighten locking nut 26, drive centring ring 25, utilize the downforce of locking nut by the projection 9 on cutter outer wall sleeve, make cutter fastening further.Compared with blocking locking with original invention one side, locking effect of the present invention obviously better also more easily mounts and dismounts.Projection 9 height on general cutter outer wall sleeve is a little more than turnbarrel inwall upper groove 240.1mm, and effect is best.Described locking nut 26 inwall is printed on screw thread, and turnbarrel 22 outer wall upper end is printed on screw thread, and locking nut is threaded with turnbarrel.Locking nut 26 surface is printed on annular knurl, adds friction, is convenient to locking nut 26 and tightens or unscrew.In practice, the projection 9 on cutter outer wall sleeve, centring ring groove 29, turnbarrel inwall upper groove 24 are all designed to be square and can obtain good fastening effect.
As shown in Figure 6 as improving further, in order to make to screw or unscrew cutter holder turnbarrel 22 in locking nut 26 process can not follow rotation at installation or removal cutter.Lock hole 32 is had in the middle part of described cutter holder turnbarrel 22, containing stop valve 33 on cutter holder, stop valve end is provided with back-moving spring 34, when pressing stop valve 33, stop valve pin 35 enters turnbarrel lock hole 32, pin turnbarrel, screw or unscrew locking nut 26, can cutter be installed or removed; When unclamping stop valve 33, because spring tension makes stop valve pin 35 exit turnbarrel lock hole 32, stop valve 33 sets back.
Pinning turnbarrel immediately for the ease of pressing stop valve 33, further have changed in the middle part of cutter holder turnbarrel 22 and having lock hole 32 for multiple.Use and processing cost consideration through comprehensive in practice, in the middle part of cutter holder turnbarrel 22, open 4 lock holes 32 can meet use needs.Lock hole 32 is designed to ellipse more easily makes stop valve pin 35 enter and be retracted into lock hole 32.
For a person skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized with other form.Therefore no matter from which point, embodiment all should be regarded as exemplary, and right and wrong are determinate, scope of the present invention is limited by claims instead of above-mentioned explanation, is therefore intended to all changes dropped in the equivalency implication of claim and scope to include in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, although should be appreciated that this description is described according to embodiment, not each embodiment only comprises an independently technical scheme, this narrating mode of description be only used to clear for the purpose of, other modes that it will be appreciated by those skilled in the art that.
