Abstract
The invention discloses a kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus and method, device comprises 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.When product diameter and pitch change need adjustment time, come loose bolt, rotate handwheel, thus drive worm screw to rotate, support core is driven to rotate around carriage center by worm gear again, until support core is adjusted to need behind position set bolt again, thus final drive shaft and support angle are changed, play the effect of electrodeless adjustment.Good effect of the present invention is: by electrodeless adjusting device of the present invention and method, fundamentally can eliminate the location due to angle, and the not fertile difficult problem of different product, support core can be adjusted to any ideal position by the present invention.
Description
Technical field
The present invention relates to a kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus and method.
Background technology
During existing three-roll thread rolling machine final drive shaft angle design, directly determine the angle position that three axles are mutual and with horizontal angle position, but along with continuous increase and the change of product, the angle of the angle that three axles are mutual and machine tool horizontal face A has been determined and has fixed, cannot rotate, original final drive shaft angle can not be used for the production of various product.As depicted in figs. 1 and 2, Fig. 1 is former support front view, the former support top view of Fig. 2, three the main transmission axis hole opposite brackets marked in FIG itself, relatively-stationary, just can not change through machining, so after product diameter and pitch change in process of production, just occurring one, product quality is defective; Two, to slow etc. problem.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus and method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of for three-roll thread rolling machine final drive shaft angle stepless adjusting apparatus, comprise handwheel, worm screw, worm gear, support core and support, 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.
Present invention also offers a kind of three-roll thread rolling machine final drive shaft angle stepless changing method, comprise the steps:
Step one, support core is made hollow, then Machining Arc slot bolt hole on support;
Step 2, worm gear is connected with support core with the first flat key after assemble by the basic size angle set, then with bolt, support core is fixed on support by arc groove bolt hole;
Step 3, on worm screw, install handwheel, and by the second flat key, handwheel is connected with worm screw;
Step 4, assemble bearing at worm screw two ends, with bearing gland, worm screw is fixed on support, and adjusts fit-up gap;
Step 5, when product diameter and pitch change need adjustment time, come loose bolt, rotate handwheel, thus drive worm screw to rotate, support core is driven to rotate around carriage center by worm gear again, until support core is adjusted to need behind position set bolt again, thus final drive shaft and support angle are changed, play the effect of electrodeless adjustment.
Compared with prior art, good effect of the present invention is: by electrodeless adjusting device of the present invention and method, fundamentally can eliminate the location due to angle, and the not fertile difficult problem of different product, support core can be adjusted to any ideal position by the present invention.

Detailed description of the invention
A kind of be used 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, second flat key 10 etc., wherein:
Worm gear 5 is connected with support core 7 by the first flat key 6, and support core 7 is fixed on support 9 by four bolts 8; Worm screw 2 is fixed on support 9 by bearing gland 3 and bearing 4; Bearing 4 is assemblied on worm gear 5, worm screw 2 is installed handwheel 1, by the second flat key 10, handwheel 1 is connected with worm screw 2.
As shown in Figure 6, drive worm screw 2 to rotate by second flat key 10 that rotates through of handwheel, handwheel 1 mainly plays corrective action in this design for the shape of described handwheel 1 and structure;
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, thus 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 through 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, thus 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 being fixed on lathe by support 9, play support and corrective action.
Present invention also offers a kind of three-roll thread rolling machine final drive shaft angle stepless changing method, comprise the steps:
Step one, support 9 core is made hollow, then on support, process four arc groove bolts hole;
Step 2, worm gear 5 is connected with support core 7 with the first flat key 6 after assemble by the basic size angle set, then with four bolts 8, support core 7 is fixed on support 9 by four arc groove bolts hole;
Step 3, on worm screw 2, install handwheel 1, and by the second flat key 10, handwheel 1 is connected with worm screw 2;
Step 4, assemble bearing 4 at worm screw 2 two ends, with bearing gland 3, worm screw 2 is fixed on support 9, and adjusts fit-up gap;
Step 5, when product diameter and pitch change need adjustment time, come loose four bolts 8, rotate handwheel 1, thus drive worm screw 2 to rotate, drive support core 7 around support 9 center rotating by worm gear 5 again, until support core 7 adjust to need position after fix four bolts 8 again, thus final drive shaft and support angle are changed, play the effect of electrodeless adjustment.
