A preferred embodiment is named, and completely illustrates the utility model in conjunction with attached drawing to become apparent from.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right",The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on the figure orPositional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or member of indication or suggestion meaningPart must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
As shown in Figure 1, the embodiments of the present invention disclose a kind of electric box dampening assembly, it is connected to execution unit 10On, electric box dampening assembly includes: electric box 20 and connection parts 30, connection parts 30 are fixed on execution unit 10, electric box 20It is connected in connection parts 30, electric box 20 is spaced apart by connection parts 30 with execution unit 10；It is offered in connection parts 30 logicalHole 31 has the first damper region 32, has between through-hole 31 and the side of connection parts 30 between through-hole 31 and execution unit 10There is the second damper region 33, there is third damper region 34, the first damper region 32 is for absorbing between through-hole 31 and electric box 20Vibration from execution unit 10, the second damper region 33 is for absorbing the vibration from the first damper region 32, third dampingRegion 34 is for absorbing the vibration from the second damper region 33；The area of the coefficient of elasticity of connection parts 30 and through-hole 31 is at anti-Than.
Specifically, a through-hole 31 is opened in the connection parts 30 between electric box 20 and execution unit 10, so that electric box20 and the connection of execution unit 10 limber up, be the flexibility for increasing electric box 20 from the perspective of rational mechanics, so that vibration passesElastic deformation occurs at connection parts 30 for the energy passed, and is converted to elastic potential energy, forms the contact form dealt with soft tactics firmly.
In the electric box dampening assembly of the present embodiment, by digging through hole 31 in the connection parts 30 of transmitting vibration, thusThe region that can transmit vibration in connection parts 30 is reduced, the first damper region 32, the second damper region 33 and third damping are formedThe area in region 34, through-hole 31 is bigger, and the coefficient of elasticity of connection parts 30 is just smaller, and the energy for passing over vibration makes to coupleComponent 30 generates elastic deformation in the edge of through-hole 31, increases connection parts 30 itself for the absorbability of vibration, fromAnd less vibration is made to be passed to electric box 20, play the role of that electric box 20 is protected to prevent connecting terminal therein from loosening.
In the electric box dampening assembly of the present embodiment, the shape of the inner wall of through-hole 31 is smooth curve.The inner wall of through-hole 31It is designed to smooth curve, can be avoided the problems in stress collection.
In the electric box dampening assembly of the present embodiment, through-hole 31 is slotted eye.Slotted eye can be by transmitting vibrationPath is elongated, further strengthens damping effect.
In the electric box dampening assembly of the present embodiment, what the short axle and execution unit 10 of through-hole 31 shook to the transmitting of electric box 20Direction is parallel, and the long axis of through-hole 31 is perpendicular to short axle.Between execution unit 10 and electric box 20, more flat connection parts 30 are formedStructure, the occupied space of connection parts 30 can be reduced while guaranteeing damping effect, so that the knot of electric box dampening assemblyStructure is more compact.
In the electric box dampening assembly of the present embodiment, the minimum widith of the first damper region 32 is less than the second damper region 33Minimum widith.The vibration of first damper region 32 can be rapidly transferred to the second damper region 33, so that vibration can be fastThe two sides of through-hole 31 are accumulated to fastly.
In the electric box dampening assembly of the present embodiment, the minimum widith of third damper region 34 is less than the second damper region 33Minimum widith.The vibration of second damper region 33 is not allowed to be readily transferred to third damper region 34, is further reduced electric box 20Vibration.
In the electric box dampening assembly of the present embodiment, connection parts 30 are steel plate.On the steel plate after aperture, the area of steel plateBecome smaller, rigidity declines, it is prone to which elastic deformation thus can use the toughness of steel plate, guarantee damping effect.
In the electric box dampening assembly of the present embodiment, the junction of connection parts 30 and execution unit 10 is provided with damping memberPart.For example, increasing rubber pad between connection parts 30 and execution unit 10, further strengthened using damper elements such as rubber padsThe damping effect of connection parts 30.
The invention also discloses a kind of die casting machines, including electric box dampening assembly as described above.
At work, the vibration of execution unit 10 is inevitable die casting machine, but can be held by cutting off or loweringTransmitting of the vibration of row component 10 to electric box 20 prevents the vibration of electric box 20 from the connecting terminal in electric box 20 being caused to loosen to reachThe problem of.Vibration, the connection parts 30 that can be provided with through-hole 31 caused by execution unit 10 effectively absorb in die casting machine,To protect the connecting terminal in electric box 20, so that it will not loosen because of vibration, the operation of entire die casting machine is influenced.
Electricity box dampening assembly provided by the utility model and the die casting machine with it, by the connection parts for being provided with through-hole 3130 absorb the vibration from execution unit 10, and will shake the both ends for accumulating in the long axis of slotted eye, reduce and are transmitted to electricityVibration on box 20 reduces a possibility that connecting terminal in electric box 20 loosens, to improve the terminals in electric box 20The electrically connected reliability of son.
