Description
Technical field
The utility model is related to a kind of gravity casting equipments, more particularly, to a kind of switching mechanism of casting machine.
Background technology
Existing part gravity-assist pouring machine is equipped with switching mechanism, generally use hydraulic cylinder driving overturning, due to liquid
Shake how much is will produce in the driving switching process of pressure, has apparent impact endurance test shock afterwards in place, to pouring sand mold in mold etc.
Phenomena such as will produce vibrations dislocation, influences yield rate.
Invention content
The utility model provides a kind of switching mechanism of the casting machine driven by servo motor；It solves in the prior art
There are problems that switching process will produce vibrations.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：A kind of casting machine
Switching mechanism, including rack and the overturning seat that is rotatably connected to thereon, the rotation axis of overturning seat is horizontally disposed, and feature exists
In：The rack is equipped with servo motor, and the output shaft of servo motor and the rotation axis of overturning seat are sequentially connected, are set in rack
The pillar closed can be supported with the overturning seat bottom of horizontality by having, and should be supported and be closed the rotation axis side that position is located at overturning seat.Servo
The output shaft of motor and the rotation axis of overturning seat are sequentially connected, therefore overturning seat can be driven by servo motor and be flipped to one side,
Servo motor smooth running, therefore the vibratory sensation of overturning seat is smaller, while reversal rate is adjustable.Overturning seat can be in the support of pillar
Lower holding horizontality.
Preferably, the rack is equipped with planetary reduction gear, and the rotation axis of its output end and overturning seat is coaxially solid
It connects, the output shaft of servo motor and the input terminal of planetary reduction gear are coaxially connected.Between servo motor and the rotation axis of overturning seat
It is connected with planetary reduction gear, planetary reduction gear has that small, gear range is big, efficient, smooth running, noise are low, suitable
The features such as Ying Xingqiang.
Preferably, the transmission ratio of the planetary reduction gear is 1 ︰, 300~1 ︰ 200.The transmission ratio of planetary reduction gear is 1 ︰
300~1 ︰ 200, the torque provided drive the rotation of overturning seat, and small volume enough.
Preferably, the length ratio of overturning seat rotation axis both sides is 0.65~0.75.Overturning seat rotation axis both sides
Length is than determining that servo motor needs torque to be offered, and for length than smaller, the torsion that overturning seat starting overturning needs is bigger.And work as
When overturning seat flip angle increases, the deflecting force of overturning seat gradually increases, and length ratio is bigger, and the deflecting force of overturning seat is bigger, because
This considers, this section is more suitable 0.65~0.75 for the length ratio of overturning seat rotation axis both sides.
Preferably, the post top portion is equipped with rubber block.The rubber block of post top portion contribute to weaken overturning seat with
Impact when post top portion contacts, reduces the vibrations of fuselage.
Therefore, the utility model has the characteristics that compared with prior art：1. overturning seat can be driven by servo motor and be turned over
Turn, smooth running and vibratory sensation is smaller, while reversal rate is adjustable；2. being connected between servo motor and the rotation axis of overturning seat
Planetary reduction gear, planetary reduction gear have the characteristics that small, efficient, smooth running, noise are low.
Description of the drawings
Attached drawing 1 is the front view of the utility model；
Attached drawing 2 is the portions the A enlarged drawing of attached drawing 1；
Attached drawing 3 is the side view of the utility model.
Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment 1：See Fig. 1, Fig. 2 and Fig. 3, a kind of switching mechanism of casting machine, including rack 1 and is rotatably connected to thereon
Overturning seat 2, the rotation axis of overturning seat 2 is horizontally disposed, and rack 1 is equipped with servo motor 3, the output shaft of servo motor 3 with
The rotation axis of overturning seat 2 is sequentially connected, and rack 1 is equipped with can support the pillar 4 closed with 2 bottom of overturning seat of horizontality, and should
It is located at the rotation axis side of overturning seat 2 to conjunction position.The output shaft of servo motor and the rotation axis of overturning seat are sequentially connected, therefore
Overturning seat can be driven by servo motor and be flipped to one side, servo motor smooth running, therefore the vibratory sensation of overturning seat is smaller, together
When reversal rate it is adjustable.Overturning seat can keep horizontality under the support of pillar.
See Fig. 1, rack 1 is equipped with planetary reduction gear 5, and the rotation axis of its output end and overturning seat 2 is coaxially affixed, servo
The output shaft of motor 3 and the input terminal of planetary reduction gear 5 are coaxially connected.It is connected between servo motor and the rotation axis of overturning seat
Planetary reduction gear, rack are equipped with the fixing piece 11 for fixing servo motor and planetary reduction gear, and planetary reduction gear has body
The features such as product is small, gear range is big, efficient, smooth running, low, adaptable noise.
The transmission ratio of planetary reduction gear 5 is 1 ︰, 300~1 ︰ 200.The transmission ratio of planetary reduction gear is 1 ︰, 300~1 ︰ 200,
The torque of offer drives the rotation of overturning seat, and small volume enough.
See Fig. 1, the length ratio of 2 rotation axis both sides of overturning seat is 0.65~0.75.The length ratio of overturning seat rotation axis both sides
Determine that servo motor needs torque to be offered, for length than smaller, the torsion that overturning seat starting overturning needs is bigger.And work as overturning seat
When flip angle increases, the deflecting force of overturning seat gradually increases, and length ratio is bigger, and the deflecting force of overturning seat is bigger, therefore comprehensive
Consider, this section is more suitable 0.65~0.75 for the length ratio of overturning seat rotation axis both sides.
