Detailed description of the invention
As shown in figures 1-8, Precise Position System for feeding, discharge station core pallet described in the utility model, comprise frame 1, described frame 1 is positioned at up/down material station place and arranges one section of rollgang controlled by variable-frequency motor 2, described rollgang 2 both sides are respectively arranged with side clamping device 3 and the side positioner 4 of two groups of mounted in pairs, according to rollgang 2, can increase or reduce the quantity of side clamping device 3 and side positioner 4, be as the criterion so that location, side accurately can be carried out.Described rollgang 2 two ends are respectively arranged with along direct of travel advance positioner 5 and clamping device 6 of advancing.
Described positioner 5 of advancing is identical with the structure of clamping device 6 of advancing, include advance cylinder and the air cylinder support 7 of advancing be fixed in described frame 1, described cylinder block 8 both sides of advancing are flexibly connected with described air cylinder support 7 of advancing by bearing pin, advance piston rod 9 end of cylinder is hinged with T-shaped push rod 10, the upright arm of described T-shaped push rod 10 is hinged on ears bearing 11, described ears bearing 11 is fixed in described frame 1, and the free end of described T-shaped push rod 10 is provided with the first hold-fast body; Described frame 1 is also provided with the limited block 12 of advancing on cylinder piston rod 9 direct of travel being positioned at positioner 5 of advancing, for limiting the length that T-shaped push rod 10 stretches out, the accurately contact position of location the first hold-fast body and core pallet.
Described side clamping device 3 comprises the thruster air cylinder support 13 be fixed in described frame 1, horizontally disposed thruster cylinder 14 is connected on described thruster air cylinder support 13, the piston rod of thruster cylinder 14 connects horizontal push 15, and the end of described horizontal push 15 is provided with the second hold-fast body.Described side positioner comprises the thruster support 16 be fixed in described frame 1, and described thruster support 16 connects horizontal pin 17, and the end of described horizontal pin 17 is provided with the 3rd hold-fast body.Above-mentioned horizontal push 15 is concordant with core tray bottom with the height of horizontal pin 17, makes the second hold-fast body and the 3rd hold-fast body can clamp core pallet under thruster cylinder 14 acts on.
Above-mentioned first hold-fast body, the second hold-fast body are identical with the structure of the 3rd hold-fast body, namely described push rod end is provided with groove, the live bearing 19 be connected on bearing pin 18 is provided with in described groove, described bearing 19 both sides are provided with pad 20, bearing pin 18 end is provided with check ring 21.Contact with core pallet with the live bearing 19 that can roll around bearing pin 18, reduce active force when hold-fast body contacts with core pallet, reduce the collision to core pallet.Meanwhile, use pad 20 and check ring 21 slow down the active force between live bearing 19 and push rod.
Above-mentioned frequency conversion rollgang 2 arranges a deceleration position and a position of rest, after core pallet arrives deceleration position, rollgang 2 speed of service drops to about 30% of normal speed by VFC, slow operation reaches position of rest and stops, and ensures that core pallet can relatively accurately be parked within the stroke range that clamp system cylinder can clamp on four sides.
Afterwards, the thruster cylinder 14 being arranged on two side clamping devices 3 of core pallet side starts, and the position set by side positioner 4 making core pallet arrive opposite side completes and clamps the location of core pallet; The cylinder of advancing of the positioner 5 of advancing of direct of travel starts, the desired location making T-shaped push rod 10 arrive positive stop 12 to have limited, then the cylinder of advancing of clamping device 6 of advancing starts, core pallet is arrived clamping that position set by positioner completes core pallet on direct of travel.
Atmospheric control as shown in Figure 8, is made up of source of the gas three linked piece, magnetic valve, pressure regulator, cylinder, magnetic switch etc.The supply gas pressure of two cylinders of advancing of direct of travel can be regulated separately by pressure regulator, the compressed air pressure adjustment that the cylinder of advancing of advancing positioner 5 uses is higher, the compressed air pressure used of cylinder of advancing of clamping device 6 of advancing is lower, the desired location making core pallet only arrive positioner when the clamping device 6 that is subject to advancing advances the thrust of cylinder to limit, thus the position of accurate location core pallet direction of advance.
So far, core pallet completes accurately location and clamping, and after robot completes gripping work, each hold-fast body unclamps, and core pallet enters next station by rollgang 2; Then new pallet arrives, and clamp system repeats the above-mentioned course of work.
