Abstract
The utility model discloses a stepless adjusting apparatus for an angle of a driving transmission shaft of a three-roller fiber grinding machine. The stepless adjusting apparatus comprises a hand wheel, a worm, a worm gear, a rack core and a rack, wherein the worm is connected with the rack core; the rack core is fastened on the rack; the worm and a bearing gland are fastened on the rack via a bearing; the bearing is assembled on the worm gear; and the hand wheel is mounted on the worm gear. When the diameter and a screw pitch of a product change and adjustments are needed, a bolt is loosened and the hand wheel is rotated to drive the worm to rotate; and the rack core is driven by the worm gear to rotate surrounding the center of the rack until the rack core is adjusted in a desired position and the bolt is fastened, so an angle between the driving transmission shaft and the rack is changed and a stepless adjustment is achieved. The stepless adjusting apparatus for the angle of the driving transmission shaft of the three-roller fiber grinding machine is advantageous in that a problem that different products cannot be produced due to angle position can be totally solved; and the rack core can be adjusted to any desired positions.
Description
Technical field
The utility model relates to a kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus.
Background technology
When existing three-roll thread rolling machine final drive shaft angle design, directly determine angle position that three axles are mutual and with horizontal angle position, but along with continuous increase and the variation of product, the angle that three axles are mutual and the angle of machine tool horizontal face A have been determined and have fixed, cannot rotate, original final drive shaft angle can not be used for the production of various products.As depicted in figs. 1 and 2, Fig. 1 is former support front view, the former support top view of Fig. 2, three relative supports of main transmission axis hole that mark in Fig. 1 itself, relatively-stationary, can not change through just machining, so after product diameter and pitch change in process of production, just occur one, product quality is defective; The problem such as two, speed is slack-off.
Utility model content
The utility model has overcome shortcoming of the prior art, provides a kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus.
The technical solution of the utility model is: a kind of three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus that is used for, comprise handwheel, worm screw, worm gear, support core and support, and described worm gear connects with support core, and described support core is fixed on support; Described worm screw is fixed on support by bearing and bearing gland; Described bearing assemble is on worm gear, and described handwheel is arranged on worm screw.
Compared with prior art, the utility model has the advantages that: by electrodeless adjusting device of the present utility model, can fundamentally eliminate the location due to angle, the not fertile difficult problem of different product, the utility model can be adjusted to support core any ideal position.

The specific embodiment
A kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus, as shown in Fig. 3 to 5, comprise handwheel 1, worm screw 2, bearing gland 3, bearing 4, worm gear 5, the first flat strong 6, support core 7, bolt 8, support 9, the second flat key 10 etc., wherein:
The shape of described handwheel 1 and structure as shown in Figure 6, drive worm screw 2 to rotate by the rotation of handwheel by the second flat key 10, and handwheel 1 mainly plays corrective action in this design;
As shown in Figure 7, worm screw 2 is rotated under the drive of handwheel 1 for the shape of described worm screw 2 and structure, thereby drives worm gear 5 to rotate;
The shape of described bearing gland 3 and structure as shown in Figure 8, play fixing worm screw 2;
The shape of described worm gear 5 and structure are as shown in Fig. 9,10, and worm gear 5 rotates by the first flat key 6 and drives support core 7 to rotate;
As shown in Figure 11,12, support core 7 rotates under worm gear 5 drives, thereby final drive shaft and support angle are changed, and plays the effect of electrodeless adjustment for the shape of described support core 7 and structure.
The shape of described support 9 and structure are as shown in Figure 13,14, and effect is fixed support core 7 and final drive shaft, makes support core 7 around its center rotating, by support 9 is fixed on lathe, plays and support and corrective action.
