Abstract
The utility model discloses a herringbone gear symmetry scribing device, which comprises a scribing tool and a parallel tool. The parallel tool consists of two steel plates and two adjustable screws, the two adjustable screws are disposed between the two steel plates, and two ends of each adjustable screw are connected with the two steel plates by nuts. The scribing tool comprises a base, a scribing rod, two scribing needles and adjustable bolts, the scribing rod is fixed onto the base, and the two scribing needles are perpendicularly mounted on the scribing rod by the adjustable bolts. The herringbone gear symmetry scribing device realizes symmetry of a herringbone gear by means of directly scribing on a machine tool, the quality of the machined herringbone gear is improved, and work efficiency is enhanced. In addition, the herringbone gear symmetry scribing device has the advantages of simplicity and convenience in operation, capabilities of guaranteeing the quality of the product and improving production efficiency, high universality and the like.
Description
Technical field
The utility model belongs to the Machining Technology field, is specifically related to a kind of herringbone bear symmetry chalker.
Background technology
Herringbone bear after earlier a flank of tooth being machined, takes off workpiece and winches to face plate in gear hobbing processing, is the line of symmetry that benchmark marks another flank of tooth with this flank of tooth, carries out another flank of tooth processing.Because error is bigger in the scratching process, and twice clamping of workpiece cause error, not only wastes man-hour, also normal poor, the inhomogeneous quality problems of transverse tooth thickness of processing back gear teeth centering property that occur.These quality problems often cause big, the gear load skewness of assembling back rotational noise, have reduced the intensity of gear, also reduce the advantage that the double helical tooth transmission is possessed.
The utility model content
The technical problem that the utility model solves provides a kind of herringbone bear symmetry chalker, causes processing the problem of the processing of back herringbone bear to the neutrality difference to solve the error that twice clamping of repetition cause, and increases work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of herringbone bear symmetry chalker is provided, comprises the line frock; It is characterized in that also comprising II font frock; Said II font frock comprises two block plates, two adjusting screws; Said two adjusting screws are arranged between two block plates; The two ends of said adjusting screw are connected with two steel plates through nut.
Said line frock comprises base, draws bar, two scribers and adjustable bolt; Said stroke of bar is fixed on the base; Said two scribers are vertically mounted on through adjustable bolt and draw on the bar.
The herringbone bear symmetry chalker that the utility model provided not only solves the problem of symmetry through directly on lathe, ruling, and has improved the quality of processing back herringbone bear, but also has improved operating efficiency; In addition, this herringbone bear symmetry chalker also have easy to use, guarantee product quality, enhance productivity, advantage such as highly versatile.
Description of drawings
Fig. 1 is the structural representation of II font frock.
Fig. 2 is the structural representation of line frock.
Fig. 3 uses sketch map for herringbone gear mesh degree of title chalker.
Wherein, 1, II font frock; 11, steel plate; 12, nut; 13, adjusting screw; 2, line frock.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is carried out detailed description.
Herringbone bear symmetry chalker comprises II font frock 1 and line frock 2;
As shown in Figure 1, II font frock 1 comprises two block plates 11, two adjusting screws 13; Two adjusting screws 13 are arranged between two block plates 11; The two ends of adjusting screw 13 are connected with two steel plates through nut 12.
As shown in Figure 2, line frock 2 comprises base, draws bar, two scribers and adjustable bolt; Draw bar and be fixed on the base, two scribers are vertically mounted on through adjustable bolt to be drawn on the bar.Two scribers can move up and down along drawing bar.
During use, as shown in Figure 3, process a lateral tooth flank after, the opposite side flank of tooth two ends of needs line are polished flat with file and oilstone.Gentian violet is smeared at position in the needs line, so that the identification of line back.
Then II font frock 1 is fixed on two increments inboard through adjusting screw 13, gear to be processed is placed on the mold, and Machining of Gear is placed on II font frock 1 top; And make Machining of Gear and gear keeping parallelism to be processed; Be close to steel plate 11 with line frock 2 then and marking two parallel lines on Machining of Gear and the gear to be processed respectively; This moment, two parallel lines on the Machining of Gear can have four intersection points with the teeth groove two edges on the Machining of Gear; With four intersection points is that basic point is drawn four four vertical lines perpendicular to four parallel lines with square; Parallel lines on four vertical lines and the gear to be processed also have four intersection point a, b, c, d at this moment; Respectively with ab and cd line, just be the teeth groove that to process at last.
The above only is the preferred implementation of the utility model; Under the prerequisite that does not break away from the utility model principle; Those skilled in the art; Be easy to the utility model is carried out some improvement and modification, these improvement and modification also fall in the protection domain of the utility model claim.
