Abstract
The utility model relates to a gear mounting tool, in particular to a gear-hobbing clamp with ball centering. The clamp is characterized in that a centering shaft of a clamp body is sleeved by a centering shaft sleeve, centering steel balls are mounted on the centering shaft sleeve, a flat gasket is installed at the upper end of the centering shaft sleeve, a stretching shaft is mounted at the upper end of the flat gasket, and the shaft end of the stretching shaft is sleeved by a shaft hole of the clamp body. The utility model has simple structure; due to the radial centering and smoothing functions of the steel balls on the centering shaft sleeve, the installation of a workpiece through the clamp body doesn't require a large radial run-out, and a clearance can be eliminated as soon as the installation is completed, thereby achieving convenient, firm and reliable installation; the gear hobbing of multiple gear workpieces can be fulfilled at the same time; and the ball type positioning shaft sleeve is adopted: experiments prove that the ring of steel balls placed between a workpiece inner bore and the positioning shaft axis can achieve very convenient installation of workpieces and ensure the compliance to technological requirements.
Description
One, technical field:
The utility model relates to the gear erecting tools, particularly the gear hobbing anchor clamps.
Two, background technology:
The manufacturer of present engine timing gear, the workshop need be equipped with a large amount of gear-hobbing machines, utilizing the gear hobbing anchor clamps to carry out workpiece installs, roll the most of axle location, gap of adopting of tool anchor clamps, the axis hole fit tolerance is H7/g6, for the workpiece of endoporus less than φ 100mm, gap axle anchor clamps can satisfy instructions for use.But, be 147.8 as endoporus for some gear
0 + 0.03, the gear of mm adopts gap axle location gear hobbing effect bad especially, and when anchor clamps axle gap hour, the workman installs workpiece wastes time and energy, and labour intensity is big, is unfavorable for execute-in-place; When anchor clamps axle gap was big, the circular runout of gear hobbing backgear reached 0.06-0.08mm, can not satisfy technological requirement.Therefore, be badly in need of a kind of novel gear hobbing anchor clamps at present and solve this difficult problem.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of ball centering gear hobbing anchor clamps are provided, and is rational in infrastructure, can satisfy the workpiece location, again can Fast Installation.
The technical scheme that the utility model is adopted for achieving the above object is: ball centering gear hobbing anchor clamps, suit centering axle sleeve on the clamp body centration axis, centration axis puts the centering steel ball is housed, plain cushion is equipped with in the centration axis set upper side, the lacing wire axle is equipped with in the plain cushion upper end, and the axle head of lacing wire axle is sleeved in the clamp body axis hole.
Described centering axle sleeve adopts centration axis to put and has a plurality of ball holes, movable setting-in ball in the ball hole.
The utility model is simple in structure, because centration axis puts steel ball radial centering, slick and sly effect is arranged when clamp body is installed workpiece, does not have when therefore installing and circular runout is bigger, promptly can eliminate the gap after the installation, easy for installation, and solid and reliable, can carry out gear hobbing to a plurality of workpiece gears simultaneously.Adopt ball-type centering axle sleeve, find between the workpiece endoporus and the centering diameter of axle, to put a circle steel ball by test, very convenient when workpiece is installed, can guarantee technological requirement again.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model centration axis nested structure schematic diagram.
Five, the specific embodiment:
Ball centering gear hobbing anchor clamps as shown in Figure 1, suit centering axle sleeve 4 on the centration axis 3 of stepped clamp body 6, the centering axle sleeve as shown in Figure 2, have a plurality of ball holes on the centering axle sleeve 4, movable setting-in ball 10 in the ball hole, plain cushion 2 is equipped with in centering axle sleeve 4 upper ends, and lacing wire axle 1 is equipped with in the plain cushion upper end, and the axle head of lacing wire axle is sleeved in the clamp body axis hole.
During work: clamp body 1 bottom surface wiped clean be placed on the gear hobbing machine worktable 9, bolt 8 is tightened slightly, look for the diameter of axle and end face run-out≤0.003 of clamp body 6 with dial gauge, tight a bolt a clamp body 6 fixedly on the platen 9, the axle sleeve 4 of will feeling relieved again is sleeved on the centration axis 3, at last workpiece 5 is contained in outside the clamp body centering axle sleeve 4, put plain cushion well, open the switch of hydraulic jack 7, by lacing wire axle 1 workpiece is clamped, the starting lathe begins workpiece gear is carried out gear hobbing, checks workpiece circular runout≤0.04 after the gear hobbing, profile of tooth, technological requirement is satisfied in teeth directional tolerance≤0.018.
Claims (2)
1. ball centering gear hobbing anchor clamps is characterized in that: suit centering axle sleeve on the clamp body centration axis, and the centering axle sleeve has the steel ball adjective-centre structure, and plain cushion is equipped with in the centration axis set upper side, and the lacing wire axle is equipped with in the plain cushion upper end, and the axle head of lacing wire axle is sleeved in the clamp body axis hole.
