Blocking.
Hard limiting device 8 is also fixed on the grinding machine saddle 1, hard 8 backstop of limiting device is in mobile backing plate 2
Slide along direction both ends side wall.Since 2 layers of mobile backing plate are opened loop control, it can not achieve the Real-time Feedback of mill rack position, lead to
Limiting device 8 really up to the mark realizes the limit for two positions that mobile backing plate 2 moves, and guarantees the starting point and terminal two of mobile backing plate 2
The precision of a position.
Linear grating ruler is additionally provided on the mobile backing plate 2, linear grating ruler can incude mill frame moving distance and communication
In the control system of grinding machine.Closed-loop control is formed by servo motor and linear grating ruler, to realize Real-time Feedback to grinding machine
Control system, it is ensured that grinding position and stock removal are accurate.
The saddle is equipped with the first track 9, and first can be slidingly positioned in by being formed on mobile 2 downside surface of backing plate
The first sliding block 10 in track 9, mobile 2 upper side of backing plate are equipped with the second track 11, grind and are formed on frame downside surface
The second sliding block that can be slidingly positioned in the second track 11.Realize that mobile backing plate 2 and mill frame movement are led by the first and second track
To guarantee movement is accurate, smooth, wherein the first and second guide rail most preferably v-shaped structure, the first and second sliding block is matching triangle
Shape structure realizes the effect of automatic centering.
The positioning device 4 is the clamping oil sac being fixedly installed on saddle, and the oil sac can clamp mobile backing plate 2
Side wall.Mobile backing plate 2 it is mobile in place when (reach home or initial point position), by that can make to clamp to oil sac oil inlet is clamped
Oil sac expansion clamps mobile 2 side wall of backing plate, and oil sac optimal distribution, can be equal for multiple oil sacs in mobile 2 two opposite sides of backing plate
Even distribution, such as each four oil sacs in every side, symmetrical, clamping oil sac can be L-shaped structure, and one side wall, which is fixedly mounted on, to be dragged greatly
On plate, another side wall and the first track 9 form corresponding relationship, while the contained structure of indent is formed on mobile 2 side wall of backing plate,
It clamps another side wall expansion of oil sac and is on the one hand correspondingly formed the positioning of the clamping to the first sliding block 10 with the first track 9, on the other hand,
The corresponding indent contained structure side wall tight against mobile 2 two sides of backing plate of oil sac positioned at mobile 2 two sides of backing plate, is realized to mobile backing plate
2 close sandwiched realizes the stable position of mobile backing plate 2, when needing mobile backing plate 2 mobile, need to only make to clamp oil sac
Oil extraction clamps oil sac and shrinks, easy to use, can be by being arranged on grinding machine to oil inlet and the oil extraction control for clamping oil sac
Switch, it is easy to use by switch control oil circuit oil supply and oil extraction.
It is additionally provided with oil-feeding control system, the oil-feeding control system includes oil pump 12, oil pipe, check valve 13, high-pressure filteration
Device 14, valve block 15 and return filter 16, the oil pump 12 are set in the fuel tank of grinding machine, and the oil outlet of oil pump 12 is suitable by oil pipe
Sequence is connected to check valve 13, high pressure filter 14 and 15 oil inlet of valve block, the hydraulic cylinder and clamping oil sac point of first driving device 3
Be not connected to the actuator port in valve block 15, the oil return opening of valve block 15 be connected to by oil pipe with return filter 16 and finally with mill
