The tooth aligning tool is arranged above a gear and comprises a positioning support and a spherical pin, wherein the spherical head part of the spherical pin is positioned in tooth socket of the gear; the positioning support includes a top plate and two baffles respectively arranged on two ends of the top plate; the spherical pin is inserted into the top plate; fastening bolts are arranged on the baffles on the distal end of the spherical pin. The tooth aligning tool provided by the utility model is simple in structure and convenient to operate, and can accurately position the keyway processing position and greatly improve the processing efficiency and the product quality.
Description
Technical field
The utility model relates to the technical field of gear keyway processing, especially a kind of tooth shaft key groove to tooth frock.
Background technology
In multi-gear transmission, often there is the requirement of synchronism, therefore on an axle or when the gear of gear shaft self and two or more gears of installation engage with the gear of pairing, how to ensure transmission uniformity, just depend on the machining accuracy of gear shaft and gear.
Control gear transmission synchronism is a processing difficult problem accurately, the strict centering in its designing requirement keyway center and gear tooth slot center (straight-tooth), or require keyway center and the strict centering in teeth groove center (helical teeth) apart from increment place fixed range; This designing requirement has increased the difficulty of keyway processing.The processing of the keyway of existing external gear wheel, owing to can not determining accurately the position of keyway, so, after keyway processing, just there will be deviation, reduce operating efficiency.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of tooth shaft key groove to tooth frock.
The utility model solves the technical scheme that its technical problem adopts: a kind of tooth shaft key groove to tooth frock, be arranged on the top of gear, comprise locating support and ball pin, the bulb part of ball pin is positioned at the teeth groove of gear, locating support has top board and two baffle plates, two baffle plates are separately positioned on the two ends of top board, and ball pin is plugged on top board, on the baffle plate that is positioned at ball pin far-end, are provided with fastening bolt.
The described locating support being made up of top board and two baffle plates is U-shaped.
Described ball pin is bolted to connection on top board.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to operate, and the accurately Working position of positioning spline has improved working (machining) efficiency and the end product quality of keyway significantly.

Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Tooth shaft key groove as shown in Figure 1, Figure 2 and Figure 3 to tooth frock, be arranged on the top of gear 4, comprise locating support 1 and ball pin 2, the bulb part of ball pin 2 is positioned at the teeth groove of gear 4, locating support 1 has top board 11 and 12, two baffle plates 12 of two baffle plates and is separately positioned on the two ends of top board 11, and ball pin 2 is plugged on top board 11, on the baffle plate 12 that is positioned at ball pin 2 far-ends, be provided with fastening bolt 3, another baffle plate 12 is affixed with the end face of gear.
The locating support 1 being made up of top board 11 and two baffle plates 12 is U-shaped, and ball pin 2 is bolted to connection on top board 11.
Below operating process of the present utility model is described:
(1), the baffle plate 12 close with ball pin 2 is close on the location end face of gear 4 on locating support 1, screws fastening bolt 3, makes locating support 1 fixing;
(2), moving up and down ball pin 2 makes bulb be close in teeth groove (roll flute);
(3), determine bulb in ball pin 2 and the contact gap of the left and right gear teeth flank of tooth with clearance gauge, guarantee the equal gapless of the left and right flank of tooth, fixing ball pin 2;
(4), firmly screw trip bolt 3, and again determine the equal gapless that contacts of bulb and the left and right gear teeth flank of tooth with clearance gauge;
(5), shown in Fig. 3, centering A face, in the beating of length direction ≯ 0.005, in the time adjusting, is only adjusted gear position;
Show (six), again gear shaft Up Highway UHW and side bus to beat ≯ 0.01, fine finishining keyway finished product.
The utility model is closely tied and is touched by bulb in ball pin 2 and teeth groove two flank of tooth, and centering teeth groove center, to determine the position of keyway.
Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
