Advantage of the present utility model and beneficial effect are:
(1) the utility model produces oscillating movement up and down by four bars machinery, and along with the conveying axis rotating speed constantly changes, vibration frequency also changes, make powder in the rotary course of roller continuously, fall in the casing uniformly.
(2) the utility model adopts spiral conveying mechanism (conveying axis), will deliver to the powder delivery mouth of pipe uniformly by the powder that the powder bucket falls, and by changing the powder feeding rotating speed of motor, changes the rotating speed of spiral conveying mechanism, advances face and accurately controls powder sending quantity.
(3) Compressed Gas in the utility model air inlet pipe will be delivered to evenly continuous the delivering in cladding laser surfaces and the laser fast shaping molten bath of powder of the powder delivery mouth of pipe, and when the conveying axis stall, powder feeding is also along with stopping powder feeding start and stop precise control.
(4) the utility model has solved the problem that existing powder feeder is difficult to carry superfines by above-mentioned (1), (2), (3), has realized the even conveying of superfines, obtained that cladding layer is continuous, bed thickness evenly, boundary FGM clearly.
(5) the utility model compact conformation, most of component materials adopts aluminium, processing easily, volume is little, light weight, good economy performance.
(6) the utility model good airproof performance adopts O-ring seals to connect between the non-moving part, adopt the JO RunddichtringO to be connected between tumbler conveying axis 8 and the fixture, has improved sealing greatly.
(7) the utility model is selected stepper motor for use, with the rotating speed of better control roller 12, realizes that the size of powder sending quantity is adjustable continuously.
(8) the powder bolt is equipped with at the utility model powder bucket top, and the dress powder is easy to operate.
(9) the utility model is installed observation window on casing, in laser melting coating and laser fast shaping process, and the operating position that can observe powder.
(10) control valve is arranged at the utility model powder bucket top, can regulate a barrel internal pressure, keeps the bucket internal pressure relatively stable.
(11) variable factor is few in the utility model course of work, has reduced governing factor, only needs the control step motor speed just can control powder sending quantity, easy operating, powder sending quantity precise control.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of four bar oscillating mechanisms.
The specific embodiment:
As Fig. 1-shown in Figure 2: a kind of vibrating screw synchronous powder feeder based on four-bar mechanism, form by powder bucket, body, conveying axis 8, four bar oscillating mechanisms 12, gas circuit and several parts of power source.The powder bucket is fixed on the body.Conveying axis 8 inserts in the body.Four bar oscillating mechanisms 12 are in the powder bucket.Connect by conveying axis 8 between power source and the four bar oscillating mechanisms 12.The powder bucket is made up of dress powder bolt 13, powder bung 2, powder staving 3, balance tracheae 1, control valve 14.Powder bung 2 is arranged on the powder staving 3.Dress powder bolt 13 is arranged on the powder bung 2.Balance tracheae 1 is inserted in the powder staving 3 by powder bung 2.Control valve 14 is arranged in the balance tracheae 1.Power source is made up of interconnective reductor 9 and stepper motor 4, and reductor 9 is connected with conveying axis 8.Body is made up of casing 6 and the observation window 11 that is arranged on the casing 6.Gas circuit is made up of air inlet pipe 5 that is fixed on casing 6 both sides and flour extraction pipe 10.Do not adopt seal with O ring between the moving part, adopt 7 sealings of JO shape sealing ring between the tumbler.
Operation principle:
During work, stepper motor drives the conveying axis rotation by reductor, and the JO RunddichtringO has guaranteed the good isolation of conveying axis casing and ambient atmosphere in rotary course.Four bars concussions mechanism is along with the continuous vertical tremor of conveying axis, make powder in the four-bar motion process continuously, fall in the casing uniformly.Spiral conveying mechanism (conveying axis) will be delivered to the powder delivery mouth of pipe uniformly by the powder that the powder bucket falls.Compressed Gas in the air inlet pipe will deliver to the powder of the powder delivery mouth of pipe evenly continuous deliver to laser skilled worker district, when the conveying axis stall, powder feeding is also along with stopping powder feeding start and stop precise control.
The balance tracheae is inflated in the powder bucket by the control of control valve in the process of powder feeder work, guarantees the air pressure balance in the powder bucket.
In the process of powder feeder work, regulate the speed of powder feeding by the control step rotating speed of motor.
