The specific embodiment
As shown in Figure 1, a kind of bias cutter comprises pedestal 1, rotates workbench 2 and the controlling organization that connects with described pedestal 1, and wherein controlling organization comprises micro-adjusting mechanism 3, detent mechanism 4 and retaining mechanism 5.Micro-adjusting mechanism 3 is used for carrying out the angle fine setting of workbench 2 with respect to pedestal 1; Detent mechanism 4 is used for locating fast; Retaining mechanism 5 is used for pinning workbench 2, makes it fixing with respect to pedestal 1.
Extremely shown in Figure 5 as Fig. 2, detent mechanism 4 comprises backstay 41 and columniform position fixing handle 42, wherein position fixing handle 42 connects rotationally on workbench 2, be set with support 23 on the workbench 2, backstay 41 passes support 23 and can connect in axial sliding on workbench 2, groove 11 is located to be provided with in precalculated position on pedestal 1 (for special angle or angle commonly used), position fixing handle 42 can drive backstay 41 by rotation and produce displacement in the axial direction, makes backstay can select to cooperate with groove 11.
Also be provided with the location relieving mechanism that backstay 41 is fixed between backstay 41 and the position fixing handle 42 with pedestal 1 disengaging configuration the time.As shown in Figure 4, the location relieving mechanism comprises the alignment pin 431 that connects with backstay 41 and is arranged on edge cam, gathering sill 433 and stop groove 434 on the position fixing handle 42, wherein backstay 41 passes gathering sill 433 and connects with alignment pin 431, and alignment pin 431 drives backstays 41 and slides into stop groove 434 along edge cam.As shown in Figure 5, edge cam comprises the first inclined-plane 432a, the second inclined-plane 432b and the 3rd inclined-plane 432c, wherein the second inclined-plane 432b has the face of the gradient and it connects the first inclined-plane 432a and the 3rd inclined-plane 432c respectively, and stop groove 433 is arranged on the 3rd inclined-plane 432c.
As shown in Figure 2, be installed with spacer 411 on the backstay 41, flexible member (is spring in the present embodiment, can certainly be other element well-known to those having ordinary skill in the art, as stage clip, torsion spring or the like) 412 be set on the backstay 41 and between spacer 411 and position fixing handle 42.
As shown in Figure 6, rotary location handle 42 makes alignment pin 431 skid off stop groove 433 and slides into the first inclined-plane 432a along the second inclined-plane 432b, simultaneously under the elastic force effect of spring 412, drive backstay 41 and connect with groove 11, detent mechanism is in positioning states and in stable condition; As shown in Figure 7, rotary location handle 42 makes alignment pin 431 slide along the second inclined-plane 432b from the position of the first inclined-plane 432a, and when alignment pin 431 slipped into stop groove 433, backstay 41 was thrown off with groove 11, and backstay 41 is in non-positioning states and in stable condition.At this moment rotary table 2 is just very convenient.Certainly,, or between backstay 41 and position fixing handle 42, the location relieving mechanism is not set, directly yet rotary table 2 eaily of rotary location handle 42 if there is not the stop groove can make it be in stable state yet.
As shown in Figure 2, retaining mechanism 5 comprises that the set lever 52 of check lock lever 51, column type, the flexible member 21 that closely connects on workbench 2 (are shell fragment in the present embodiment, can certainly be other elastomeric material), pedestal is provided with the flange 12 that cooperates with flexible member 21.
Cooperation and the set lever 52 of check lock lever 51 by flange and groove connects and is in the same place.Rotational lock handle 52, check lock lever 51 can be endwisely slipped, and close to the direction of flange 12 when check lock lever 51, check lock lever 51 will make shell fragment 21 match with flange 12, also just make workbench 2 be locked at (as shown in Figure 7) on the pedestal 1 securely, retaining mechanism is in locking state.Rightabout rotational lock handle 52 makes check lock lever 51 move to the direction away from flange 12, and shell fragment 21 and flange 12 are separated, just pedestal 1 rotation (as shown in Figure 8) relatively of workbench 2 at this moment, and retaining mechanism is in non-locking state.
As shown in Figures 2 and 3, the regulating rod 31 that micro-adjusting mechanism 3 comprises the trimming handle 32 of column type, connect with trimming handle 32, first gear 33 and with second gear 34 of first gear, 33 engagements, check lock lever 51 rotatable being set in the regulating rod 31, regulating rod 31 and check lock lever 51 coaxial settings, trimming handle 32 and set lever 52 coaxial settings.Second gear 34 fixedly connects or takes shape on the regulating rod 31.First gear 33 is for fixedly connecting the tooth bar of the annular on pedestal 1.Regulating rod 31 rotatably connects in workbench 2.The cooperation by flange and groove of trimming handle and regulating rod 31 connects is in the same place.In order to realize the angle fine setting of workbench 2 better with respect to pedestal 1, between second gear 34 and first gear 33, set up a transmission mechanism 35, transmission mechanism 35 is designed to reducing gear, it comprises and is arranged on the 3rd gear 351 on the support 23 rotationally and is set in the 4th gear 352 on the check lock lever 51 rotationally, the 3rd gear 351 is meshed with described second gear 34, and the 4th gear 352 is meshed with the 3rd gear 351 and first gear 33 respectively.
As shown in Figure 8, when needing quick adjustment workbench 2 with respect to the angle of pedestal 1, rotational lock handle 52 makes retaining mechanism 5 be in non-locking state; Simultaneously, rotary location handle 42 makes detent mechanism 4 be in non-positioning states; Direct push work platform 2 makes engagement on the 4th gear 352 and first gear 33 then, realizes quick adjustment.
As shown in Figure 8, when needs fine settings workbench 2 during with respect to the angle of pedestal 1, retaining mechanism 5 is in non-locking state; Simultaneously, detent mechanism 4 is in non-positioning states; At this moment the rotary fine adjustment handle 32, make regulating rod 31 with respect to check lock lever 51 rotations, drive second gear, 34 engagements the 3rd gear 351 and rotate, the 3rd gear 351 drives the 4th gear 352 again and rotates along first gear 33, finely tunes with respect to pedestal 1 angle thereby carry out workbench 2.
As shown in Figure 7, when workbench 2 arrives required angle, rotational lock handle 52, make check lock lever 51 close to the direction of flange 12, when making shell fragment 21, check lock lever 51 is resisted against securely on the flange 12 of pedestal 1, also just make workbench 2 be locked at securely on the pedestal 1, at this moment retaining mechanism 5 is in locking state, and detent mechanism 4 is in non-positioning states.
As shown in Figure 6, when needs workbench 2 with respect to pedestal 1 at 15 degree fast during the location, rotary location handle 42, make alignment pin 431 skid off stop groove 433 and slide into the first inclined-plane 432a along the second inclined-plane 432b, at this moment rotary table 2, when near groove 11 places at 15 degree places, under the elastic force effect of spring 13, drive backstay 41 and connect, just navigate to 15 degree places fast with groove 11; At this moment retaining mechanism 5 is in non-locking state, and detent mechanism 4 is in positioning states,
In sum, the position fixing handle 42 rotatable workbench 2 that are arranged at just can make detent mechanism be in non-positioning states by rotary location handle, can rotate freely workbench 2; And between backstay 41 and position fixing handle 42, be provided with the location relieving mechanism, and just make that when needs workbench 2 rotates freely with respect to pedestal 1 it is more stable that detent mechanism is in non-positioning states, like this, make simple in structure, easy to operate.
