Abstract
The utility model relates to the technical field of gear wire-cut EDM (electrode discharge machining) and discloses a gear tip center positioning tool. The gear tip center positioning tool comprises a tooth-aligning bar and two tooth-aligning blocks. One side of each tooth-aligning block is provided with aligning teeth matching with gear teeth of a gear to be machined. The center of each tooth-aligning block is provided with a central-symmetrical tooth-aligning block keyway. Before positioning, the two tooth-aligning blocks are disposed at corresponding positions on the gear teeth respectively; two ends of the tooth-aligning bar penetrate through the tooth-aligning block keyways of the two tooth-aligning blocks respectively; the tooth-aligning bar is located on the surface of the gear to be machined and passes through gear keyways of the gear to be machined; and center lines of the tooth-aligning bar, the tooth-aligning block keyways and the gear keyways overlap. The gear tip center positioning tool is simple in structure and can be used to quickly and accurately determine gear tip centers of the gear to be machined.
Description
Technical field
The utility model relates to gear line cutting technology field, particularly relates to a kind of tooth top centralized positioning frock.
Background technology
When the enterprising line cutting of machine tool, because helical gear is helix at its tooth length direction, be involute at gear teeth to direction, so be difficult to determine the gear teeth tips center.Mostly adopt at present manual line manually-operated, because manually-operated stability and accuracy can not be guaranteed, easily cause larger error, and take time and effort.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is how to determine fast and exactly the gear teeth tips center.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of tooth top centralized positioning frock, comprise tooth bar and two the tooth piece, described one side to the tooth piece have that the gear teeth with gear to be processed are complementary to tooth, described center to the tooth piece has centrosymmetric to tooth piece keyway; During the location, two described is installed in respectively on the relative position of the described gear teeth the tooth piece, described two ends to tooth bar pass respectively two described to the tooth piece to tooth piece keyway, on the described card that tooth bar is positioned at described gear to be processed and the gear keyway by described gear to be processed, described to tooth bar, to the central lines of tooth piece keyway and gear keyway.
Wherein, each is described on the tooth piece tooth being respectively equipped with two groups, two groups of described two ends that tooth laid respectively at described the same face to the tooth piece.
Wherein, described width to tooth piece keyway is consistent with the width of described gear keyway.
(3) beneficial effect
A kind of tooth top centralized positioning frock that technique scheme provides, the gear teeth to tooth and gear to be processed to the tooth piece closely mesh, fixedly positioning, tooth bar is passed two to the tooth piece and is tiled on the card of gear to be processed, to the center line of tooth bar and central lines to tooth piece keyway, so that two this tooth top centralized positioning tool structure is simple to the tooth top center by the gear teeth that are meshed with it, the center of tooth piece, can be fast and determine exactly the tooth top center of gear to be processed.

Fig. 3 is the side view to the tooth piece of the present utility model.
Wherein, 1, to tooth bar; 2, to the tooth piece; 2a, to tooth; 2b, to tooth piece keyway; 3, gear to be processed; 3a, the gear teeth; 3b, gear keyway.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 and Fig. 2, a kind of tooth top centralized positioning of the utility model frock, comprise tooth bar 1 and two tooth piece 2, this one side to tooth piece 2 have that gear teeth 3a with gear 3 to be processed is complementary to tooth 2a, have centrosymmetric to tooth piece keyway 2b to the center of tooth piece 2; During the location, these two are installed in respectively on the relative position of gear teeth 3a tooth piece 2, to the two ends of tooth bar 1 pass respectively two to tooth piece 2 to tooth piece keyway 2b, tooth bar 1 is positioned on the card of gear 3 to be processed and the gear keyway 3b by this gear 3 to be processed, to tooth bar 1, to the central lines of tooth piece keyway 2b and gear keyway 3b.
Identical with modulus and the helical angle of the gear teeth 3a of gear 3 to be processed to tooth 2a to tooth piece 2 so that tooth piece 2 and gear 3 to be processed are closely meshed, fixedly positioning; Tooth bar 1 is adopted the high ruler of linearity, tooth bar 1 is passed two to tooth piece 2 and is tiled on the card of gear 3 to be processed, to the center line of tooth bar 1 respectively with central lines to center line and the gear keyway 3b of tooth piece keyway 2b, so that two to the tooth top center by the gear teeth that are meshed with it, the center of tooth piece 2, then realized by tooth bar 1 being determined the position fixing process at tooth top center.The tooth top centralized positioning frock that present embodiment provides, simple in structure, can be fast and determine exactly the tooth top center of gear 3 to be processed.
Preferably, consistent with the width of gear keyway 3b to the width of tooth piece keyway 2b, to guarantee exactitude position.Further, the width of tooth bar 1 is complementary respectively with to the width of tooth piece keyway 2b and the width of gear keyway 3b.
Such as Fig. 3, for easy to operate, and guarantee that two lines of centres to tooth piece 2 pass through gear centre to be processed, each is to being respectively equipped with two groups to tooth 2a on the tooth piece 2, two groups lay respectively at two ends to the same face of tooth piece 2 to tooth 2a, each to tooth piece 2 to tooth piece keyway 2b open these two groups to tooth 2a between.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
