Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Embodiment 1:
With reference to Fig. 1, present embodiments provide it is a kind of can with the high-speed rod-rolling mill for carrying adjustment roll gap, including cabinet 1 with
And the left adjustment mechanism 2 and right adjustment mechanism 3 being arranged symmetrically, left adjustment mechanism 2 and right adjustment mechanism 3 include roll 4, bias
Set 7, worm screw 5 and worm gear 6, roll 4 are pivotally mounted to eccentric bushing 7, and 5 both ends of worm screw are rotatably connected with cabinet 1, and worm gear 6 is pacified
On eccentric bushing 7,5 engaged transmission of worm gear 6 and worm screw, the axis of worm gear 6 and the eccentric axis of roll 4 are arranged.
The present invention drives the axial rotation of worm gear 6 to realize left tune so that roll 4 be made to generate eccentric motion by the rotation of worm screw 5
The adjusting of the roll gap size of roll 4 between complete machine structure 2 and right adjustment mechanism 3；The adjusting of 4 eccentric motion of roll passes through worm and gear
5 transmissions are adjusted, and since 5 tooth of worm screw is continuously helical tooth, it and 6 tooth of worm gear are to progress into engagement and gradually move back
It engages out, while the tooth engaged, to also more, therefore, the position that roll 4 is adjusted during 4 crimping of roll is born
Shock loading it is smaller, to keep the roll gap adjustment process of roll 4 more steady, and noise is low, at the same avoid result in by compared with
Large impact leads to the problem of adjusting roll gap failure, realizes the roll gap with load control roll 4 during rolling line；In addition, snail
5 worm-drive of bar has the characteristics that self-locking, can prevent from being made to move by compared with big load during 4 rolling line of roll, into
The quality and the degree of reliability of one step raising milling train rolling line.
Further, the worm gear 6 of the present embodiment is connected with the preload piece 8 for tightly engaging worm gear 6 and worm screw 5, makes
The position of engagement of worm gear 6 and worm screw 5 fits closely, and reduces the impact generated due to rolling line process, improves what worm and gear 5 was driven
Stability；Specifically, 8 both ends of preload piece in the present embodiment respectively with the worm gear 6 of left adjustment mechanism 2 or eccentric bushing 7 and right tune
The worm gear 6 or eccentric bushing 7 of complete machine structure 3 connect, and the snail of left adjustment mechanism 2 is respectively acting on by the interaction force of preload piece 8
On the worm gear 6 of wheel 6 and right adjustment mechanism 3, facilitate save the cost.
Wherein, preload piece 8 is spring, cylinder or hydraulic cylinder etc..
Further, cabinet 1 offers mounting hole, and deep groove ball bearing 10 or sliding shaft sleeve are arranged in mounting hole, improves
The efficiency that worm screw 5 rotates, the rotation of worm screw 5 is more smooth, while reducing and wearing between worm screw 5 and cabinet 1, improves equipment and uses the longevity
Life；And deep groove ball bearing 10 bears biggish radial load, stablizes to improve worm screw 5 in the case where bearing 4 load of roll
It adjusts.
Further, worm screw 5 is connected with servo motor 9, and servo motor 9 is connected with for measuring 9 output shaft of servo motor
The rotary encoder of angular displacement can measure the angular displacement of 9 output shaft of servo motor, by computer by angle by rotary encoder
Displacement is converted into the center displacement amount of roll 4, so that the center displacement of angular displacement and roll 4 that worm screw 5 rotates is connected,
It is more convenient that the roll gap distance of 4 rolling line of roll is adjusted, improve rolling line efficiency.
Embodiment 2:
With reference to Fig. 2, the present embodiment the difference from embodiment 1 is that, 8 one end of preload piece of the present embodiment and worm gear 6 or partially
7 connection of heart set, the other end and cabinet 1 connect, and make 6 position of worm gear of left adjustment mechanism 2 and right adjustment mechanism 3 will not mutual shadow
It rings, improves the stability that worm and gear 5 is driven.
Further, worm screw 5 is connected with the rotary encoder for measuring 5 angular displacement of worm screw, can pass through rotary encoder
The angular displacement that worm screw 5 rotates is measured, angular displacement is converted into the center displacement amount of roll 4 by computer, thus by 5 turns of worm screw
Dynamic angular displacement and the center displacement of roll 4 connect, more convenient that the roll gap distance of 4 rolling line of roll is adjusted, and improve
Rolling line efficiency.
To sum up, first, the present invention realizes the adjusting of 4 roll gap of roll by the cooperation of 5 worm gear 6 of worm screw, while meeting and rolling
Roll 4 adjusts the requirement of roll gap when bearing compared with big load during system, adjusts roll gap during the rolling process without shutting down, improves
The production efficiency of rolling line；Second, the degree of stability of 4 position of roll during rolling line is improved, 4 crimping process of roll is realized
It is self-locking；Third engages 6 worm screw 5 of worm gear closely, reduces worm and gear 5 and is driven the impact being subject to；4th, make the inclined of roll 4
Heart amount of movement and the angular displacement of worm screw 5 connect, and facilitate the eccentric amount of movement for adjusting roll 4, improve 4 roll gap adjustment of roll
Accuracy.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
