Description

Inside spline wheel gear teeth groove is to teeth groove gear-shaping clamp

Technical field

This utility model belongs to clamp art, specifically, relates to a kind of inside spline wheel gear teeth groove to teeth groove gear-shaping clamp。

Background technology

A kind of inside spline wheel gear, as shown in Figures 3 and 4, it is desirable to two internal spline teeth groove and teeth groove central alignment, must be not more than 0.10mm to positive error。According to product two internal spline structure analysis: the two internal spline numbers of teeth are identical, the graduated arc space width of the 3rd tooth 13 is more than the second tooth 12, and the 3rd tooth 13 tooth root dia is more than the second tooth 12。Take first the first tooth 11 to be rolled shaving for this process technology scheme, then process two internal splines with the first tooth 11 para-position, and add a kind of fixture that can adapt to this processing mode of man-hour requirement。

Utility model content

For solving above technical problem, the purpose of this utility model is in that to provide a kind of inside spline wheel gear teeth groove to teeth groove gear-shaping clamp, simple in construction, manufacture economy, spacing by common normal clamp, after initial workpiece adjustment accurately, follow-up batch machining para-position is both accurate, and efficiency is high again。

This utility model purpose is achieved in that a kind of inside spline wheel gear teeth groove is to teeth groove gear-shaping clamp, it it is critical only that: includes pedestal and base, described base is fixedly mounted on pedestal, the circular stopper slot laying gear it is provided with in the middle part of described base, periphery along described stopper slot is provided with common normal clamp and at least two hold down gag on described base, the center of described stopper slot is pointed in described common normal clamp one end, and have draw-in groove at this end, described hold down gag is symmetrically distributed in described stopper slot edge with the extended line of common normal clamp direction for line of symmetry。

The corresponding described common normal clamp of above-mentioned base is provided with limit sliding chutes, this limit sliding chutes points to the center of described stopper slot, described common normal clamp bottom is positioned at described limit sliding chutes, described common normal clamp is bolted on described base, the bolt through-hole of this common normal clamp is waist-shaped hole, and this waist-shaped hole be arranged in parallel along the glide direction of described common normal clamp。

Above-mentioned hold down gag includes pressing plate and column, and this column is vertical with described base to be fixed, and described pressing plate one end is locked by the top of bolt Yu described column。

The bottom of above-mentioned stopper slot has downwards discharge opening, and on described pedestal, corresponding described discharge opening is provided with through hole。

Beneficial effect:

This utility model one inside spline wheel gear teeth groove is to teeth groove gear-shaping clamp, simple in construction, utilize rotationally symmetrical principle, the first tooth 11 para postion is limited at alignment mark process common normal clamp, stable holding gear, thus can reprocess the 3rd tooth 13 after same batch of the second tooth 12 processes, its base tangent length is controlled because processing the first tooth 11, and tolerance is less, when therefore selecting its para-position, circumference pivot angle is negligible, second tooth 12 the 3rd tooth 13 teeth groove para-position Center Technology is required, and being not more than 0.10mm may be limited in its claimed range completely, reduce mismachining tolerance, improve machining accuracy, manufacture economy, spacing by common normal clamp, after initial workpiece adjustment accurately, follow-up batch machining para-position is both accurate, efficiency is high again。

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail。

Embodiment:

As illustrated in fig. 1 and 2: a kind of inside spline wheel gear teeth groove is to teeth groove gear-shaping clamp, it is made up of pedestal 1 and base 2, described base 2 is fixedly mounted on pedestal 1, the circular stopper slot 3 laying gear it is provided with in the middle part of described base 2, the bottom of described stopper slot 3 has downwards discharge opening 9, and on described pedestal 1, corresponding described discharge opening 9 is provided with through hole 10。

Periphery along described stopper slot 3 is provided with common normal clamp 4 and two hold down gags 5 on described base 2, the center of described stopper slot 3 is pointed in described common normal clamp 4 one end, and having draw-in groove 6 at this end, two described hold down gags 5 are symmetrically distributed in described stopper slot 3 edge with the extended line of common normal clamp 4 direction for line of symmetry。Described hold down gag 5 is made up of pressing plate 5a and column 5b, and this column 5b is vertical with described base 2 to be fixed, and described pressing plate 5a one end is locked by the top of bolt Yu described column 5b。

The corresponding described common normal clamp 4 of described base 2 is provided with limit sliding chutes 7, this limit sliding chutes 7 points to the center of described stopper slot 3, described common normal clamp 4 bottom is positioned at described limit sliding chutes 7, described common normal clamp 4 is bolted on described base 2, the bolt through-hole of this common normal clamp 4 is waist-shaped hole 8, and this waist-shaped hole 8 be arranged in parallel along the glide direction of described common normal clamp 4。

In conjunction with Fig. 1,2,3 and 4, clamp structure principle is illustrated:

A, jig Design principle: rotate 180 ° of symmetry principles, in conjunction with common normal clamp, product circumference error is limited principle。

Paint pen before b, slotting inside spline wheel gear the second tooth 12 and make alignment mark in any five tooth both ends of the surface of gear, as shown in Figure 1。

C, inside spline wheel gear is loaded fixture, it is ensured that product, in draw-in groove, is compressed with hold down gag and can insert inside spline wheel gear the second tooth 12 by the labelling gear teeth。Internal spline the 3rd tooth 13, inserting while the second tooth 12, is inserted out by this operation, and at this moment the 3rd tooth 13 graduated arc space width still has 1.08mm allowance, be thus easy to pinion cutter and teeth groove during processing the 3rd tooth 13 initial workpiece to tooth。Adjust after accurately the 3rd tooth 13 can be carried out normal production and processing in the processing of internal spline the 3rd tooth 13 initial workpiece。

Finally it should be noted that; foregoing description is only preferred embodiment of the present utility model; those of ordinary skill in the art is under enlightenment of the present utility model; under the premise without prejudice to this utility model objective and claim; can making and representing like multiple types, such conversion each falls within protection domain of the present utility model。
