Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Figures 1 to 3, a kind of small roll gap of high accuracy regulates and controls to roller mill, including：Frame, twin rollers structure, transmission mechanism
With roll gap adjustment mechanism.
Frame includes support frame 101 and the supporting table 102 for being installed on the two ends of support frame 101 with hollow installation region.
Twin rollers structure includes that two edges are parallelly mounted to the disk roller of the overhead heart installation region of support frame 101, and two disk rollers are divided into second
Upper roll wheel 202 and lower roll wheel 201 on direction, the position of wherein lower roll wheel 201 is fixed with respect to frame, and the position of upper roll wheel 202
Put, can in a second direction be adjusted so as to change two roll gaps of disk roller with respect to lower roll wheel 201.
Transmission mechanism includes belt pulley 301, driving gear 302, driven gear 303 and idler sheave assemblies 304.Belt pulley 301
It is coaxially installed on the roll shaft of lower roll wheel 201 with driving gear 302, lower roll wheel 201 is driven by motor and belt gear
And rotate；Driven gear 303 is installed on the roll shaft of upper roll wheel 202, and upper roll wheel 202 and lower roll wheel 201 pass through idler sheave assemblies 304
Constitute oppositely oriented gear drive.
Idler sheave assemblies 304 include idle pulley frame 3041, fixed mount 3042, the first idle pulley 3044, the second idle pulley 3045 and operation
Part.Fixed mount 3042 can be installed on support frame 101 by way of welding, and connecting plate is also welded with fixed mount 3042
3043, there are a pair of screwed holes on connecting plate 3043.
Idle pulley frame 3041 has a fixed part and a movable part that can be relatively fixed portion's circumferential movement；It is therein solid
Determine portion to be installed on fixed mount 3042 by the rotation of the second wheel shaft 3047, while the second idle pulley 3045 is rotated being installed on the second wheel
On axle 3047, idle pulley frame 3041 now then can be relatively fixed 3042 turns of frame by center of rotation of the axis of the second wheel shaft 3047
It is dynamic.Movable part is rotated by the first wheel shaft 3046 and installs the first idle pulley 3044, and now the first idle pulley 3044 just can be with respect to second
The circumferential movement of idle pulley 3045.Operating parts is that can fit into the bolt 3049 in screwed hole, its end abutment idle pulley frame 3041
So as to drive the movable part portion of being relatively fixed on idle pulley frame 3041 to move when that can be moved along its axis direction.First idle pulley
3044 engage with driven gear 303, the second idle pulley 3045 can idle pulley frame 3041 rotate during all the time with driving gear
302 engage so as to realize the transmission of power.Idle pulley frame 3041 has a pair of waist type grooves, the energy during activity of idle pulley frame 3041
It is enough to realize its fixation with fixed mount 3042 by loading bolt in waist type groove 3048.
Roll gap adjustment mechanism includes the first sliding part 402 for moving along the first direction for a pair and is used to for a pair support twin rollers
The second sliding part 403 that one of disk roller is moved in a second direction relative to another disk roller in structure.Each second sliding part 403
Respectively it is movably installed in each supporting table 102 so as to produce displacement in a second direction by a bearing bracket stand 401.Each
First sliding part 402 is respectively movably installed in each supporting table 102 so as to produce along first party by a drive mechanism
To displacement.Specifically, each drive mechanism there is one can be produced around own axis and moved along its axis direction
Leading screw 404, one end of leading screw 404 connects an output shaft for servomotor 406, and the other end is rotated by an end cap 405
It is installed in supporting table 102.Drive leading screw 404 to rotate when servomotor 406 works, the first sliding part 402 by screwed hole with
Leading screw 404 coordinates and then moves along the first direction.
First sliding part 402 is a sliding block, and it passes through the first guide rail 407 and is slidably mounted in supporting table 102, sliding block
With the first sliding surface extended along third direction.Second sliding part 403 includes bearing block 4031 and top shoe 4032, axle
The both sides of bearing 4031 are slidably mounted on bearing bracket stand 401 by second guide rail 408 respectively, the bearing block 4031 and upper roller
The roll shaft of wheel 202 coordinates so as to form movable supporting to upper roll wheel 202.Top shoe 4032 is fixed on bearing block 4031, its tool
Having can constitute the second sliding surface being slidably connected along third direction with the first sliding surface.The angle of third direction and first direction
Less than 45 °, so that sliding block shift value in a first direction is more than the shift value in a second direction of top shoe 4032.
In the present invention, first direction refers to the X-direction in Fig. 2, should be with ground or supporting table in actual application
102 table top is parallel.Second direction refers to the Y direction in Fig. 2, should be with ground or supporting table 102 in actual application
Table top it is vertical.Third direction refers to the Z-direction in Fig. 2, should be coplanar with X-axis and Y-axis in actual application and be made and X
The angle of axle is small as far as possible.
In the present invention, in order to ensure degree of regulation, roll gap adjustment mechanism can be installed with axial symmetry or mirror-image fashion, be double
Mechanism's link gear.
As shown in figure 4, it is θ to make the angle between third direction and first direction, top shoe 4032 is in the position of second direction
It is H to move, and sliding block displacement in a first direction is S.H=Stan θ, i.e. S=H/tan θ can be tried to achieve according to trigonometric function, due to
45 ° of θ ＜, therefore S is consistently greater than H, and H is controlled by S is controlled for this.Again because the pitch of leading screw 404 is given value p, servo
The rotation number of turns of motor 406 is n, therefore S=np.In servomotor 406, number of turns n is easily controlled and the pitch p of leading screw also may be used
To select, therefore S values are also easily controlled.Specific works situation according to milling train, specific adjusting range and the precision of roll gap will
Ask, from the upper sliding block at different θ angles, although when θ adjusts very small, when required precision is very high, as long as θ values are sufficiently small, S values begin
Can amplify eventually.Because H=Stan θ=nptan θ, after S is exaggerated, as long as control n is just easily controlled roll gap essence
Degree.On the other hand, for mobile identical displacement S, the pitch p of the leading screw of selection is smaller, then number of turns n is bigger, and such one
Just can further improve the precision of roll gap.Meanwhile, screw mandrel has auto-lock function, can avoid producing roller in the course of the work
Raw relative displacement, keeps so as to further increase its roll gap precision in motion process.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvement and deformation can also be made, these improve and deform
Also should be regarded as protection scope of the present invention.
