Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, further set forth the utility model.
The utility model designs a kind of grinding machine hobboing cutter auxiliary clamp, is located in xyz system.
The table top of frame 1 is set as xy face, in x direction, guide rail 2 is set, and left and right thimble support 3,11 is set at the two ends of guide rail 2;
Described left and right thimble support 3,11 is configured on guide rail 2 movably, stretches out in opposite directions thimble;
Described left thimble support 3 stretches out a linking arm 4, and described linking arm 4 ends arrange fulcrum, are rotationally connected resilient push 5 on fulcrum;
Accompany fixed axis 9, described fixed axis 9 axis and left and right thimble dead in line at left and right thimble;
Coaxially be nested with index dial 8 at fixed axis 9 left ends, on described index dial 8 peripheries, be evenly distributed with several bayonet sockets 14, described swaging clamp 6 is most advanced and sophisticated to be inserted among bayonet socket 14;
To be processed hobboing cutter 10 is coaxially nested with at fixed axis 9 right-hand members, as shown in Figure 1, 2.
Realize left and right thimble support 3,11 horizontally slips on guide rail 2, guide rail 2 can have various structures form, can open at guide rail 2 middle parts a chute 13, have through hole at left and right thimble support 3,11 and chute 13 contact portions, through hole inside is provided with trip bolt, when needs are fixed left and right thimble support 3,11, needs only hold-down screw is tightened, when needing left and right thimble support 3,11 to slide, the hold-down screw of outwarding winding, promotes thimble support just passable, as shown in Figure 7.
As the another kind of form of slide construction, guide rail 2 can be designed to T-shaped structure, allow left and right thimble support 3,11 lower ends fasten guide rail, then set up a locking device by thimble support locking.
The blade of hobboing cutter 10 to be processed is on periphery, so need to be rotated in the time of polishing hobboing cutter 10 to be processed, index dial 8 is exactly in order to realize this function with the setting of swaging clamp 6, the bayonet socket 14 of index dial 8 and swaging clamp 6 to coordinate be the key of processing stability, if there is gap between the two, in process, be easy to so produce vibrations, so bayonet socket 14 should be that gapless coordinates with swaging clamp 6, some bayonet socket shape is to reach the requirement that gapless coordinates certainly, as gear index plate, so can be set to triangle in bayonet socket 14 sides, corresponding swaging clamp 6 tips are also set to triangle, reach stability requirement, if work in-process need to change machining angle, only mill need to be removed, promote resilient push 5, pull-out swaging clamp 6, swaging clamp 6 is separated with index dial 8, index dial 8 is rotated to an angle, then unclamp resilient push 5, so just can again start processing, the number of index dial 8 bayonet sockets 14 is also to change according to demand, requirement on machining accuracy is higher, bayonet socket 14 numbers will be more so, as shown in Figure 4.
The connection fulcrum of resilient push 5 and linking arm 4 can adopt various ways, and fulcrum of the present utility model is a rotating shaft 12, and resilient push 5 middle parts have through hole, and described through hole is enclosed within rotating shaft 12.For convenient operation, linking arm 4, left thimble and resilient push 5 can be arranged on same x, in y plane.
In sum, everyly have that index dial 8 is located, the grinding machine hobboing cutter fixture form of the fixing fixed axis 9 of left and right thimble is all within protection domain of the present utility model.
