The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
Embodiment one
With reference to shown in Fig. 1 to Fig. 7, the present embodiment one provides a kind of servo-actuated front supporting mechanism, including：Frame, adjusting means,
Drive device and follow-up material-supporting plate D；The frame includes outer stent A, middle layer bracket B and the inner stent C set gradually；Institute
Stating adjusting means includes level(l)ing mechanism and vertical governor motion, and the level(l)ing mechanism is used to drive the middle layer bracket
B is moved horizontally (certainly, middle layer bracket B and inner stent C are moved horizontally together) on the inside of the outer stent A, described
Vertical governor motion is used to drive the inner stent C to carry out vertical shift on the inside of the middle layer bracket B；The drive device
It is arranged on the inner stent C, for driving follow-up material-supporting plate D to be rotated.
Preferably, level(l)ing mechanism and vertical governor motion can be passed using adjusting handle, position indicator and leading screw
Motivation structure is constituted.
Specifically, the Level tune machine includes：Level tune handwheel 11, the first lead-screw drive mechanism and horizontal level refer to
Show device 21；First lead-screw drive mechanism is connected with the Level tune handwheel 11, for driving the middle layer bracket B in institute
State and moved horizontally on the inside of outer stent A；The horizontal situation indicator 21 is connected with first lead-screw drive mechanism, is used
In the adjustable range of display horizontal direction.
Accordingly, the vertical governor motion includes：Vertical adjusting handle 12, the second lead-screw drive mechanism and vertical position
Indicator 22；Second lead-screw drive mechanism is connected with the vertical adjusting handle 12, for drive the inner stent C in
Vertical shift is carried out on the inside of the middle layer bracket B；The vertical position indicator 22 is connected with second lead-screw drive mechanism,
Adjustable range for showing vertical direction.
Further, between first lead-screw drive mechanism and the Level tune handwheel 11, first leading screw is passed
Belt transmission is respectively adopted between motivation structure and horizontal situation indicator 21；Second lead-screw drive mechanism and the vertical tune
Belt transmission is respectively adopted between section handwheel 12, between second lead-screw drive mechanism and vertical position indicator 22.
In the present embodiment, when adjusting Level tune handwheel 11, middle layer bracket B edges are driven by the first lead-screw drive mechanism
Outer stent A inwall makees the movement in horizontal direction, and horizontal situation indicator 21 can be specific directly by what is moved horizontally
Distance values are shown, so that operating personnel check and make accurate judgment.Meanwhile, when adjusting vertical adjusting handle 12,
Inner stent C is driven to make moving on vertical direction along middle layer bracket B outer walls by the second lead-screw drive mechanism, and vertical position
Indicator 22 directly can show the specific distance values of vertical shift.
Using two adjusting handles realize to middle layer bracket B and inner stent C in the horizontal direction with the tune on vertical direction
Section, while being shown the specific distance values moved in both direction by two position indicators, so as to improve tune
Save the precision of position.Wherein, it should explanation, the first lead-screw drive mechanism drives middle layer bracket B to make horizontal direction movement
When, the inner stent C that is connected with middle layer bracket B is then internal by the second lead-screw drive mechanism while do the movement of horizontal direction
Movement on layer support C vertical directions, it is therefore an objective to so that the follow-up material-supporting plate D set is adjusted to the position needed.
The present embodiment as a specific embodiment in use, adjusting handle, position indicator, and leading screw connection
Mode has a variety of.For example：One end that leading screw is connected with position indicator and adjusting handle is provided with a pair of rotating wheels, and a pair turns
Dynamic opinion includes the first rotating wheel and the second rotating wheel, while the timing belt for transmission is same including the first timing belt 51 and second
Walk band 52.During actual installation, the first rotating wheel is connected by the first timing belt 51 with adjusting handle, and the second rotating wheel passes through
Two timing belts 52 are connected with position indicator, so can make its position indicator and leading screw when adjusting handle is rotated
Rotation is synchronized, so as to the further accuracy for improving regulation.
More specifically, in the present embodiment Level tune handwheel 11, horizontal situation indicator 21, and the first leading screw are passed
The connected mode of motivation structure；Vertical adjusting handle 12, vertical position indicator 22, and the second lead-screw drive mechanism connection side

It can be moved horizontally (while being also that the second screw mandrel 34 can be driven to be moved horizontally).In other words, middle layer bracket B is carried out
Move horizontally, C is moved horizontally and vertical shift between internal layer.
Wherein, it also should be noted that level in the present embodiment
Position indicator 21 is " 0 " (i.e. horizontal direction position indicator numerical value, the half of the lower mould V well widths of display)；It is perpendicular
Straight position indicator 22 is " 0 " (vertical direction position indicator numerical value, the lower mould height of display).Servo-actuated front supporting is before use, need
Servo-actuated front supporting center is highly adjusted according to lower mould V well widths and lower mould.
Specifically, the adjusting handle of setting serves the regulation to middle layer bracket B and inner stent location of C, due to regulation
When adjacent rack between can occur mutual friction, frictional force is excessive not only to influence the precision of regulation, can also influence whole
The service life of frame.Therefore, to ensure mobile smoothness, further in middle layer bracket B opposite sides and outer layer branch
Frame A opposite sides is attached by least one pair of horizontal guide rail 1；And middle layer bracket B opposite sides is with inner stent C's
Opposite sides is attached by least one pair of upright guide rail 2, the cunning that can be so set in movement by relative position
