Description

A kind of self-feed differential planet flat turn disc

One, technical field

The utility model relates to mechanical field, particularly a kind of self-feed differential planet flat turn disc.

Two, background technology

Facing head is the indispensable functional accessory of various boring machine radial feeds.Because the complexity of production technology and the difficulty of technology.The imitative in decades external explained hereafter of China do not have the boring machine of facing head greatly.Much there was not the old boring machine of facing head in these several years again from external import.According to China's national situation and the change of processing technology now, and the development of technology needs, machining must be used facing head.Original production does not have the boring machine transmission device mechanism of facing head simply to have no idea to transform.The various countries technical specialist once tried out multiple mode and improved, and did not all satisfy the demand of precision, and a difficult problem can't resolve for a long time, restricting the technological progress and the optimization and improvement of machining for a long time, also bring very big cost burden, thereby institute is concerned about very with being improved in the industry in the innovation of boring machine to enterprise.

Three, utility model content

At above-mentioned situation, for overcoming the deficiency of existing boring machine, the purpose of the utility model just provides a kind of self-feed differential planet flat turn disc, can effectively solve the precision of boring machine radial feed, improve the mechanical processing quality problem, the technical scheme of its solution is, the boring and milling axle is connected with facing head by straight end-face key, facing head and boring and milling axle rotate simultaneously, the boring and milling axle is equipped with the fixed wheel gear outward, be meshed with the planetary gear on the facing head, fixed wheel gear and planetary gear have tooth poor, rotation drives the planetary gear rotation, planetary gear is contained on the planet driving gear shaft, driving gear is housed on coaxial, driving gear is meshed with driven gear on the worm drive shaft, coaxial worm is arranged on the worm drive shaft, coaxial worm links to each other with worm gear, worm screw is housed on the worm gear, the driving slide plate is arranged on the facing head, driving on the slide plate has the snail bar, and worm screw links to each other with the snail bar, the rotation of worm gear drives worm screw, the snail bar that drives on the slide plate is done the radial alignment motion, driving gear and the driven gear on the worm drive shaft regulated on the planet driving gear shaft change radially feeding rate of slide plate, and the utility model is simple in structure, reliable transmission, easy to use, thoroughly having solved does not have a flat precision difficult problem of revolving the boring machine radial feed, is a creation in the mechanical machined, and economic benefit is huge.

Four, description of drawings

Accompanying drawing is a structural front view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Provide by accompanying drawing, its structure of the utility model is, boring and milling axle 20 is connected with facing head 1 by straight end-face key 19, facing head 1 rotates simultaneously with boring and milling axle 20, the boring and milling axle 20 outer fixed wheel gears 10 that are equipped with, be meshed with the planetary gear 9 on the facing head, fixed wheel gear 10 has tooth poor with planetary gear, rotation drives the planetary gear rotation, planetary gear is contained on the planet driving gear shaft 11, driving gear 8 is housed on coaxial, and driving gear 8 is meshed with driven gear 7 on the worm drive shaft 12, and coaxial worm 6 is arranged on the worm drive shaft, coaxial worm 6 links to each other with worm gear 5, worm screw 4 is housed on the worm gear, the slide plate 2 of driving is arranged on the facing head, driving on the slide plate has snail bar 3, worm screw links to each other with the snail bar, the rotation of worm gear drives worm screw, the snail bar that drives on the slide plate is done the radial alignment motion, and driving gear 8 and the driven gear on the worm drive shaft 7 regulated on the planet driving gear shaft change radially feeding rate of slide plate.

In order to guarantee result of use, said planet driving gear shaft 11 is fixed on the facing head 1 through spring bearing 13; Worm drive shaft 12 is fixed on the facing head 1 through spring bearing 14; Fixed wheel gear 10 is contained in outside the boring and milling axle, and facing head 1 is supported on two

bearings

17,18 on the fixed wheel gear 10.

Working condition of the present utility model is, the feeding of self-feed differential planet flat turn disc capstan radial alignment drives planetary gear 9 by facing head 1 and does rotation around fixed wheel gear 10, planetary gear 9 drives 8 rotations of coaxial driving gear simultaneously, drive driven gear 7 rotations that are meshed therewith by driving gear 8 again, driven gear 7 drives coaxial worm 6 and drives worm gear 5 rotations, the snail bar 3 that worm screw 4 on the worm gear 5 is driven on the slide plate 2 is done the radial alignment motion, change the number of teeth of driving gear 8 and driven gear 7, can change the radial feed speed that drives slide plate 2, unclamping straight end-face key 19 boring and milling axles can independently rotate, facing head is supported on two bearings 17 on the fixed wheel gear 10, on 18, quit work.
