The flanged plate of the portal frame and gantry ram is fastenedly connected, and constitutes dynamic pillar portal frame, and crossbeam passes through on crossbeam Lower motion is connected on portal frame and moved up and down.
The crossbeam up-down mechanism include servomotor, " one-to-two " T-shaped double-output speed reducer, two Power transmission shaft, two right angles accelerate machine and two ball screws, the input shaft of one " one-to-two " T-shaped double-output speed reducer It is connected, divides on two output shafts of one " one-to-two " T-shaped double-output speed reducer with the output shaft of shown servomotor Not Lian Jie a power transmission shaft, the ball-screw is connected through the right angle reductor with the power transmission shaft.
Firm banking is limited by communications and transportation width, is spliced by two pieces of bases, is mainly used in the mobile work of fixed, positioning Make platform and dynamic beam moves pillar Longmen machine tool.
The mobile work platform is driven by variable-frequency motor, and rail wheel, can be in firm banking track and external orbital to be oriented to Between back and forth movement.
The external orbital is made up of H profile steel welding underframe and railway, and structural rigidity is strong.
Gantry ram moves forward and backward stroke for 4.5 meters.Crossbeam moves up and down on portal frame, and up and down motion stroke is 1.5 Rice.Laser melting coating head adpting flange side-to-side movement stroke is 4.5 meters.
The seal box body is connected with firm banking outer ring, and whole gantry executing agency is placed in box house, casing On be provided with observation window and operation gloves etc..
Compared with prior art, it is an advantage of the invention that:
1st, forming area(Space utilization)Maximize, form one between square dynamic pillar gantry bed body with dynamic beam on the table The cube metal rapid shaping region of rule, under conditions of molding part size is ensured, dynamic beam moves pole structure and has accomplished close The maximization of box house space utilization is sealed, inert gas consumption and gas clarification time in casing is greatly reduced, enters One step reduces the cost of metal rapid shaping.
2nd, compared with cantilever design, the good innate advantage of gantry structure stability determines that dynamic beam moves pole structure lathe energy Enough realize large-sized metal rapid shaping.Synchronously driving crossbeam moves up and down gantry left and right pillar, compared to fixed-beam lathe, Structural stability, printing precision and headroom take all advantageously.
3rd, the development trend manufactured with laser gain material, the size of metal Quick formed part is increasing, quick to metal The physical dimension of molding machine, transmission accuracy require higher, and the present invention moves forward and backward mechanism and cladding head adpting flange in ram Side-to-side movement mechanism uses high class gear rack drives, it is to avoid because of big stroke ball-screw horizontal setting, and itself is sagging right The influence of transmission accuracy.Crossbeam up-down mechanism is using a servomotor input, the drive of two ball-screw synchronism outputs Flowing mode, the characteristic of high transmission accuracy is placed with reference to leading screw vertically, has reached that laser melting coating head is transported in metal Rapid Prototyping Process Dynamic high accuracy.
Compared with existing metal rapidform machine, the invention provides a kind of Stability Analysis of Structures, forming area(Space utilization) Maximize, the dynamic beam that printing precision is high moves pillar gantry metal rapidform machine.
