Detailed description of the invention
First embodiment:
Fig. 1-1a to Fig. 1-4 shows the clamping device Q according to first embodiment of the invention, and this clamping device Q is fixed on installation foundation plate T.The bearing 101 of clamping device Q there are 4 screw holes 115 (with reference to Fig. 1-1b), utilize 4 screws (not shown) of inserting above-mentioned screw hole 115 to be fixed on above-mentioned installation foundation plate T.The workpiece W be placed on this installation foundation plate T is clamped by above-mentioned clamping device Q.
The clamping device Q of this embodiment forms primarily of bearing 101, jig arm 103, bar 102 and clutch guide mechanism A.Jig arm 103 is positioned at outside bearing 101, for clamping work pieces W.One end of bar 102 is positioned at described bearing 101, and the other end is positioned at outside described bearing 101, and described bar 102 can rotate around the axle center of bar 102 and/or move axially.Clutch guide mechanism A is positioned at described bearing 101, be made up of initiative part B and guide portion C, initiative part B is namely positioned at the shift fork 120 on bar 102, shift fork 120 is a part for bar 102 and is connected with bar 102 one, guide portion C is the groove 132 on external thread piece 130, and this external thread piece 130 is independently parts, and it is also with vertical slot 131 and external screw thread 135, vertical slot 131 and groove 132 adjacent, in external screw thread 135 and bearing 101 with internal thread 105 form the screw thread mutually screwed togather and be flexibly connected.
The operating process of clamping device Q clamping work pieces W:
When jig arm 103 is in an open position (with reference to Fig. 1-2), the hex nut of bar 102 head is entangled with box spanner S, then rotate fast and/or move axially bar 102, shift fork 120 on bar 102 is by vertical slot 131 fast near groove 132, and jig arm 103 arrives near workpiece W position (with reference to Fig. 1-3) fast under the drive of bar 102 from open position; Continue swingle 102, shift fork 120 on bar 102 arrives groove 132 place and starts to be subject to the constraint of groove 132, groove 132 makes external thread piece 130 follow the rotation making some angles under the stirring of shift fork 120, bar 102 is by affix moving axially gradually, jig arm 103 is from close workpiece W position arrival clamped position gradually (with reference to Fig. 1-4) under the drive of bar 102, and workpiece W is clamped.
Clamping device Q unclamps the operating process of workpiece W:
When jig arm 103 is in clamped position (with reference to Fig. 1-4), the hex nut of bar 102 head is entangled with box spanner S, then swingle 102, shift fork 120 on bar 102 arrival vertical slot 131 place gradually, the constraint of shift fork 120 disengaging groove 132 gradually, groove 132 makes external thread piece 130 follow the rotation making some angles under the stirring of shift fork 120 in the process, jig arm 103 under the drive of bar 102 from clamped position arrival gradually near workpiece W position (with reference to Fig. 1-3), workpiece W is released; Continue rotate fast and/or move axially bar 102, the shift fork 120 on bar 102 leaves groove 132 fast by vertical slot 131 place, and jig arm 103 arrives open position (with reference to Fig. 1-2) fast from close workpiece W position under the drive of bar 102.
In sum, because jig arm 103 is near being move fast between workpiece W position and open position, therefore the present invention makes clamping device Q save the operating time, improves operating efficiency.
In addition, when jig arm 103 is in clamped position, be unlikely to make bar 102 to produce useless rotation under the impact being subject to cutting vibration, thus jig arm 103 generation is got loose and displacement, the clamping device Q of the present embodiment is also provided with maintaining body D, groove 132 place namely on external thread piece 130 with in inclined plane 133 and shift fork 120 with the inclined plane (not shown) matched with this inclined plane 133.Under the impact being subject to cutting vibration, bar 102 can produce the trend to vertical slot 131 direction slippage, but make bar 102 produce the trend of the opposite direction movement to vertical slot 131 due to the existence of two inclined planes, thus counteract the above-mentioned trend to vertical slot 131 direction slippage, bar 102 is remained on original position motionless.
Maintaining body D can also be that the magnetic part that guide portion C and/or initiative part B are provided with is formed, at this moment make bar 102 produce the trend of origin-location of remaining on due to the existence of magnetic part, thus counteract above-mentioned under the impact being subject to cutting vibration the trend to the slippage of vertical slot direction.Certainly also have other structures of obviously easily seeing can realize same function and effect, all do not depart from the scope of the present invention.
Second embodiment:
Fig. 2-1a to Fig. 2-5 shows the clamping device Q according to second embodiment of the invention, and this clamping device Q is fixed on installation foundation plate T.The bearing 201 of clamping device Q has 3 open slots 218 (with reference to Fig. 2-1a), utilizes 3 screws (not shown) of inserting above-mentioned open slot 218 to be fixed on above-mentioned installation foundation plate T.The workpiece W be placed on this installation foundation plate T is clamped by above-mentioned clamping device Q.
The clamping device Q of this embodiment forms primarily of bearing 201, jig arm 203, bar 202 and clutch guide mechanism A.Jig arm 203 is positioned at outside bearing 201, for clamping work pieces W.One end of bar 202 is positioned at described bearing 201, and the other end is positioned at outside described bearing 201, and described bar 202 can rotate around the axle center of bar 202 and/or move axially.Clutch guide mechanism A is positioned at described bearing 201, be made up of initiative part B and guide portion C, initiative part B is namely positioned at the finger head 222 (note: the part that finger 220 contacts with groove 232) of the finger 220 on bar 202, and finger 220 is independently parts and being fixedly connected with bar 202; Guide portion C is the groove 232 on external thread piece 230, this external thread piece 230 is independently parts, it is also with vertical slot 231 and external screw thread 235, vertical slot 231 and groove 232 adjacent, in external screw thread 235 and bearing 201 with internal thread 205 form the screw thread mutually screwed togather and be flexibly connected.
The operating process of clamping device Q clamping work pieces W:
When jig arm 203 is in an open position (with reference to Fig. 2-2), hexagonal in bar 202 head is injected with Inner die nut, then rotate fast and/or move axially bar 202, finger head 222 on bar 202 is by vertical slot 231 fast near groove 232, and jig arm 203 arrives near workpiece W position (with reference to Fig. 2-4) fast under the drive of bar 202 from open position; Continue swingle 202, finger head 222 on bar 202 arrives groove 232 place and starts to be subject to the constraint of groove 232, groove 232 makes external thread piece 230 follow the rotation making some angles under the stirring of finger head 222, bar 202 is by affix moving axially gradually, jig arm 203 is from close workpiece W position arrival clamped position gradually (with reference to Fig. 2-5) under the drive of bar 202, and workpiece W is clamped.
Clamping device Q unclamps the operating process of workpiece W:
When jig arm 203 is in clamped position (with reference to Fig. 2-5), hexagonal in bar 202 head is injected with Inner die nut, then swingle 202, finger head 222 on bar 202 arrival vertical slot 231 place gradually, the constraint of finger head 222 disengaging groove 232 gradually, groove 232 makes external thread piece 230 follow the rotation making some angles under the stirring of finger head 222 in the process, jig arm 203 under the drive of bar 202 from clamped position arrival gradually near workpiece W position (with reference to Fig. 2-4), workpiece W is released; Continue rotate fast and/or move axially bar 202, finger head 222 on bar 202 leaves groove 232 fast by vertical slot 231 place, and jig arm 203 arrives open position (with reference to Fig. 2-2) fast from close workpiece W position under the drive of bar 202.
In sum, because jig arm 203 is near being move fast between workpiece W position and open position, therefore the present invention makes clamping device Q save the operating time, improves operating efficiency.
