Abstract
The utility model relates to a plastic gear hobbing clamp. The plastic gear hobbing clamp is reasonable in design, simple to manufacture, good in universality and stable in tooth alignment position.
Description
Technical Field
The utility model relates to a plastic gear hobbing clamp, which is a hobbing clamp suitable for duplex planetary gears, and the upper planetary gear and the lower planetary gear have higher requirements on tooth angles.
Background
Because of innovation of market demands and gear design concepts, at present, part of mechanical transmission mechanisms are duplex gears with metal and plastic in press fit, and two gears have high tooth aligning angle requirements in the transmission speed process. At present, the tooth alignment is accurately positioned by detecting a tooth reader of a gear hobbing machine, and the product is a duplex gear with a compact structure, and because the tooth reader is interfered and metal cannot be detected, the accurate positioning cannot be realized, and the tooth alignment requirement can be ensured only by adjusting a head piece, but the method can cause unstable process.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide the plastic gear hobbing clamp which is reasonable in design, simple to manufacture, good in universality and stable in tooth position.
The technical scheme of the plastic gear hobbing clamp is as follows: the fixture comprises a fixture body, wherein the fixture body comprises a positioning mandrel with a ladder structure, and the positioning mandrel is sequentially provided with a first ladder section, a second ladder section, a third ladder section and a fourth ladder section from left to right;
the standard component for reading teeth is arranged on the second step section, the tooth aligning sleeve for positioning the pinion tooth slot is arranged on the third step section, the fourth step section is used for arranging a machined part, and the right end of the fourth step section is provided with a fixing nut.
The clamp body is matched with the elastic chuck of the gear hobbing machine.
Because the synchronism of the equipment is poor in the processing process, the restarting and other factors of parameter adjusting equipment can generate larger errors, and the tooth alignment position is very unstable, the utility model realizes the fixation by matching with the elastic chuck of the gear hobbing machine, arranging a metal gear standard component with the same parameters as a plastic gear on the second step section of the positioning mandrel, positioning a pinion tooth slot by arranging a tooth alignment sleeve on the third step section of the positioning mandrel, arranging a machined part on the fourth step section of the positioning mandrel, and arranging a fixed nut on the right end of the fourth step section, and strengthening the rigidity of the clamp body by the nut, thereby realizing stable tooth alignment processing.
The working flow is as follows: firstly, a metal gear standard part is arranged, then the tooth aligning angle between the metal gear standard part and a small metal planet wheel is calibrated, then, the tooth aligning probe of a gear hobbing machine is utilized, firstly, the position of the tooth of the metal gear standard part arranged at the back is aligned, then, the Y-axis position is moved in parallel to perform hobbing on a right plastic gear workpiece, the right plastic gear workpiece automatically reaches the correct position, and finally, gear hobbing is started. Therefore, the utility model can realize continuous and stable processing by only adjusting the tooth aligning angle of the first part.
Compared with the prior art, the utility model has the following advantages and effects: 1. the tooth positions are stable, and continuous stable processing can be realized; 2. the utility model has simple manufacture and lower cost; 3. the universal type gear positioning device is better in universality, and products with similar structures can be processed by changing the specification of the gear positioning standard part and the size of the positioning mandrel.
