Description
Technical field
The utility model provides the instrument of field of machining, specifically planet gear speeder pivoted frame body trisection hole processing clamp.
Background technology
Planet gear speed increaser has the movement characteristic of power dividing and rotation axis, make it have lot of advantages technically and economically with respect to the transmission of common dead axle line gear, especially those ordinary gear transmissions occasion of being difficult to meet the demands, as in light weight, compact conformation, power loss is little etc., more can bring into play its unrivaled speciality.The pivoted frame body is one of main member of planet gear speeder, and planet wheel spindle and bearing all are contained on the pivoted frame body, and it is the part that bears the moment of face maximum in the mechanism.The crudy of pivoted frame body to the load distribution between each planetary gear so that bearing capacity, noise and the vibrations etc. of transmission device all have very large influence.Lathe is difficult to fine finishining is carried out in planet gear speeder pivoted frame body trisection hole at present.
Summary of the invention
In order to overcome the deficiency of existing processing method, the utility model provides planet gear speeder pivoted frame body trisection hole processing clamp.These anchor clamps are by installing pressing plate, axle sleeve, indexable tire plate, reference pins and pivoted frame body respectively on positioning base, and by dial gauge and reference pins location, solve the technical problem of planet gear speeder pivoted frame body trisection hole processing.
The scheme that the utility model technical solution problem is adopted is: the side at positioning base is equipped with pressing plate, the positioning base center is provided with axle sleeve, indexable tire plate bottom is installed in the axle sleeve, and be pressed on the positioning base by pressing plate, three calibration reference pins are housed on the indexable tire plate, and indexable tire plate top is connected with the pivoted frame body, is provided with portable dial framework in indexable tire plate one side, point to indexable tire plate one side on it dial gauge is installed, on the portable dial framework turning handle is housed.
Good effect, planet gear speeder pivoted frame body trisection hole processing clamp not only can be processed trisection, quartering hole and many halving holes, range of application side is general.Have compact conformation, workable, machining accuracy is high, the advantage of good reliability.The suitable vertical lathe that uses uses the fine finishining of pivoted frame trisection hole.

Fig. 1 is a planet gear speeder pivoted frame body trisection hole processing clamp front view
Fig. 2 is a planet gear speeder pivoted frame body trisection hole processing clamp schematic top plan view
Fig. 3 is pivoted frame body halving hole distribution figure
Among the figure, 1. positioning base, 2. pressing plate, 3. indexable tire plate, 4. axle sleeve, 5. pivoted frame body, 6. calibration reference pins, 7. dial gauge, 8. portable dial framework, 9. turning handle.
The specific embodiment
According to illustrated in figures 1 and 2, side at positioning base 1 is equipped with pressing plate 2, the positioning base center is provided with axle sleeve 4, indexable moving tire plate 3 bottoms are installed in the axle sleeve, and are pressed on the positioning base by pressing plate 2, and three calibration reference pins 6 are housed on the indexable tire plate 3, indexable tire plate top is connected with pivoted frame body 5, be provided with portable dial framework 8 in indexable tire plate one side, point to indexable tire plate one side on it dial gauge 7 is installed, turning handle 9 is housed on the portable dial framework.
Turning handle freely moves forward portable dial framework, drives dial gauge and is pressed on the peak of calibration reference pins, and the dial gauge pointer all shows zero-bit, reaches accurate calibration purpose.
As shown in Figure 3, add man-hour carrying out pivoted frame trisection hole, at first the pivoted frame body is installed on the last plane of indexable tire plate, look for concentric solid with interior and clamping labor with anchor clamps at 0.01mm, unclamp then that chuck jaws moves the pivoted frame body with anchor clamps and centering trisection hole A with the machine tool rotary centres and clamp, the while turning handle move dial framework with list index to zero-bit.Finish turning A hole reaches the drawing requirement.Unclamp the pressing plate on the indexable tire plate then, rotate the B hole site of indexable tire plate to the trisection hole, simultaneously turning handle moves dial framework list index is clamped with pressing plate after to zero-bit, and finish turning B hole reaches the drawing requirement, and the C hole that according to said method processes the trisection hole successively reaches the drawing requirement.
The crudy of pivoted frame body is bigger to load distribution between planetary gear and stable working influence, so also higher to its requirement on machining accuracy.Deviation of centre distance will cause the radial displacement of planetary gear, when the amount of deflection of each centre-to-centre spacing and direction not simultaneously, influence between the adjacent lines star-wheel axis hole relatively string apart from the measured value of error.The planet wheel bearing hole directly influences the meshing quality of planetary gear and sun gear to the parallelism error of pivoted frame body datum axis.Adjacent lines star-wheel axis hole string influences the tangential displacement at planetary gear axis hole center, thereby influence load distribution between the planetary gear, and the error of division depends on the precision of technological equipment apart from deviation.The accuracy of manufacture of finish turning pivoted frame trisection hole anchor clamps seems most important thus.
Finish turning pivoted frame body trisection hole anchor clamps mainly are made up of positioning base, indexable tire plate and portable dial framework etc.Wherein positioning base and indexable tire plate all adopt stable good HT200 casting to make, and the depth of parallelism that goes up lower plane simultaneously all is less than 0.01mm, and surface roughness will reach
, the axle sleeve of ZQS6-6-3 is housed in the hole in positioning base, and is axially having oil-way, rotate freely in positioning base to guarantee indexable tire plate.And join the gap and will be strict controlled in the 0.01-0.02mm, guarantee the machining accuracy in trisection hole.Intermeshing rack and pinion is housed in the packaged type dial framework, dial framework is moved freely, be pressed in accurately on the calibration reference pins.
