Referring to fig. 1 to 5, an embodiment of the present application provides a device for filling an automobile suspension, which includes an automatic steel ball delivering portion 6, a lifting system, a transfer communicating portion 2, a liquid filling pipe 3, a vacuum pipe 4, a liquid feeding pipe 5, and a tool 1. The tool 1 is used for fixing the automobile suspension part 7 on a liquid filling platform so that a liquid filling hole at the bottom of the automobile suspension part 7 faces upwards. The lifting system is arranged above the tool 1, and the lifting direction of the lifting system is along the direction of the liquid injection hole of the automobile suspension part 7. The transfer communicating part 2 is arranged on the lifting system, and the transfer communicating part 2 is of a hollow structure. The top of annotating liquid pipe 3 is linked together with transit intercommunication portion 2, annotates liquid pipe 3 and is located the car suspension member 7 and annotates the liquid hole directly over. The vacuum tube 4 is communicated with the transit communication part 2. The input end of the liquid conveying pipe 5 is communicated with the transit communicating part 2, and the liquid conveying pipe 5 is used for conveying liquid into the transit communicating part 2. The steel ball automatic delivery part 6 is arranged on the transfer communication part 2, and the steel ball automatic delivery part 6 is used for automatically delivering the steel ball 8 into the transfer communication part 2 so that the steel ball 8 is driven into the automobile suspension part 7 through the liquid injection pipe 3 to seal the liquid injection hole. Valves are arranged on the liquid feeding pipe 5 and the vacuum pipe 4.
According to the device for pouring the liquid into the automobile suspension part 7, the automobile suspension part 7 is fixed on the liquid pouring platform by adopting the tool 1, so that the liquid pouring hole at the bottom of the automobile suspension part 7 is upward and is convenient for pouring the liquid. When the liquid filling is carried out, firstly, the lifting system controls the transfer communication part 2 and the liquid filling pipe 3 arranged on the transfer communication part 2 to descend, so that the bottom of the liquid filling pipe 3 is inserted into a liquid filling hole at the bottom of the automobile suspension part 7; and then the vacuum tube 4 (one end of the vacuum tube 4 is connected with a vacuum pump) vacuumizes the centering communication part 2 and the automobile suspension 7, so that the subsequent liquid can conveniently enter the cavity of the automobile suspension 7. When the vacuum degree reaches a preset value, the valve on the vacuum tube 4 is closed, the valve on the liquid feeding tube 5 is opened, the liquid feeding tube 5 starts to convey liquid into the transfer communication part 2, the liquid enters the transfer communication part 2 and then enters the automobile suspension part 7 along the liquid injection tube 3 until the liquid injection is completed, and the valve on the liquid feeding tube 5 is closed. Then the steel ball automatic delivery part 6 delivers a steel ball 8 into the transfer communication part 2, the steel ball 8 enters into the liquid injection hole of the automobile suspension part 7 along the liquid injection pipe 3 (the diameter of the steel ball 8 is slightly larger than the diameter of the liquid injection hole, at the moment, the valve of the vacuum tube 4 can be opened, the vacuum tube 4 conveys air pressure into the transfer communication part 2, under the action of the air pressure, the steel ball 8 is driven into the liquid injection hole of the automobile suspension part 7, and the hole wall of the liquid injection hole of the automobile suspension part 7 has certain elasticity, so when the steel ball 8 with the diameter larger than the inner diameter of the liquid injection hole enters into the liquid injection hole, the steel ball 8 can deform the liquid injection hole and seal the liquid injection hole), and further the sealing of the automobile suspension part 7 is realized. Therefore, the device for filling the automobile suspension part 7 provided by the embodiment of the application can finish two steps of filling the liquid and sealing the steel ball 8 on one device, and the two steps are not required to be separated on two devices, so that the production efficiency of the automobile suspension part 7 is greatly improved.
In one embodiment, the automatic steel ball feeding portion 6 includes an elastic member 64 (e.g., spring, elastic string, etc.), a steel ball conveying pipe 62, a steel ball conveying block 63, and a vertical conveying pipe 61. The bottom of the vertical conveying pipe 61 is embedded in the transit communication part 2, and the top of the vertical conveying pipe 61 is communicated with the outside; the bottom of the vertical conveying pipe 61 is provided with a vent hole communicated with the inside of the transit communication part 2 and an output hole of the steel ball 8. The steel ball conveying pipe 62 is obliquely arranged, the bottom output end of the steel ball conveying pipe 62 is communicated with the vertical conveying pipe 61, and a plurality of steel balls 8 are filled in the steel ball conveying pipe 62. The steel ball transport block 63 is slidably arranged in the vertical conveying pipe 61, an inclined through hole for accommodating one steel ball 8 is formed in the steel ball transport block 63, piston structures are arranged at the upper end and the lower end of the steel ball transport block 63, and the piston structures are in sliding sealing fit with the pipe wall of the vertical conveying pipe 61. The elastic member 64 is disposed in the vertical conveying pipe 61, one end of the elastic member 64 is connected to the vertical conveying pipe 61, and the other end of the elastic member 64 is connected to the steel ball transporting block 63.
In the initial state, as shown in fig. 2, when the automobile suspension 7 needs to be filled, firstly, the valve on the vacuum tube 4 is opened (at this time, the valve on the liquid feeding tube 5 is closed by default), and the vacuum tube 4 vacuumizes the inner cavities of the middle-turn communication portion 2 and the automobile suspension 7 under the action of the vacuum pump at one end of the vacuum tube, so that the air pressure between the middle-turn communication portion 2 and the inner cavity of the automobile suspension 7 is reduced, and the liquid is conveniently injected. Because the air pressure of the transit connection part 2 is reduced, the steel ball transportation block 63 further overcomes the elasticity of the elastic piece 64 and slides downwards (the air pressure at the upper end of the steel ball transportation block 63 is higher than the air pressure at the lower end of the steel ball transportation block 63) until the steel ball transportation block 63 moves to the position shown in fig. 3, and at this time, the steel ball 8 in the inclined through hole of the steel ball transportation block 63 can enter the transit connection part through the output hole of the steel ball 8. The mesh screen valve (the mesh screen valve can prevent the steel ball 8 from entering the automobile suspension part 7, but can not prevent the liquid from entering the automobile suspension part 7) can be arranged at the position where the middle communication part is communicated with the liquid injection pipe 3, so that the steel ball 8 entering the middle communication part is blocked by the mesh screen valve until the liquid delivery pipe 5 finishes inputting the liquid into the automobile suspension part 7, and the mesh screen valve is opened, so that the steel ball 8 enters the automobile suspension part 7 and seals the automobile suspension part 7. Because the liquid feeding pipe 5 inputs liquid into the middle communicating part, the air pressure value in the middle communicating part slowly rises and recovers, so that the pressure difference between the upper end and the lower end of the steel ball conveying block 63 is reduced, the steel ball conveying block 63 moves upwards under the action of the elastic force of the elastic piece 64 until the topmost position, at this time, the steel balls 8 in the steel ball conveying pipe 62 automatically enter into the inclined through holes of the steel ball conveying block 63 along the steel ball conveying pipe 62 under the action of self gravity due to the inclined arrangement of the steel ball conveying pipe 62 (as shown in fig. 5), so that the steel balls 8 can be automatically conveyed to the next automobile suspension piece 7.
Optionally, the length of the piston at the upper end of the steel ball conveying block 63 may be lengthened, and the distance between the communicating position of the steel ball conveying pipe 62 and the vertical conveying pipe 61 and the steel ball 8 output hole of the vertical conveying pipe 61 is larger than the diameter of the inclined through hole, so as to ensure that the steel ball conveying pipe 62 is always not communicated with the middle communicating portion in the downward sliding process of the steel ball conveying block 63, and further ensure that the air pressure state in the middle communicating portion is not damaged by the steel ball conveying pipe 62. And by lengthening the piston at the upper end of the steel ball conveying block 63, when the steel ball conveying block 63 moves to the lowest end position, the piston at the upper end of the steel ball conveying block 63 can still block the steel ball 8 in the steel ball conveying pipe 62, so that the steel ball 8 is prevented from entering the vertical conveying pipe 61 above the steel ball conveying block 63.
In one embodiment, a limiting ring is disposed in the vertical conveying pipe 61, and the limiting ring is used for limiting the highest position of the steel ball conveying block 63, so that when the steel ball conveying block 63 is at the highest position, the steel ball conveying pipe 62 is communicated with the inclined through hole of the steel ball conveying block 63. By arranging the limiting ring, after the steel ball conveying block 63 is reset to the highest position, the inclined through hole is communicated with the steel ball conveying pipe 62, so that the steel balls 8 in the steel ball conveying pipe 62 can be ensured to have enough time to enter the inclined through hole of the steel ball conveying block 63.
In one embodiment, the steel ball transfer tube 62 is angled between 2 and 4. By setting the inclination angle of the steel ball conveying pipe 62 to 2-4 degrees, the steel balls 8 in the steel ball conveying pipe 62 can automatically enter the inclined through holes of the steel ball conveying blocks 63, and meanwhile, the resistance of the steel balls 8 in the steel ball conveying pipe 62 in the downward movement process of the steel ball conveying blocks 63 can be reduced (if the inclination angle of the steel ball conveying pipe 62 is too large, the steel balls 8 in the steel ball conveying pipe 62 can give excessive pressure to the steel ball conveying blocks 63, so that the steel ball conveying blocks 63 are difficult to move).
In one embodiment, the liquid filling pipe 3 comprises a connecting sleeve 33, a liquid filling hose 32 (which can be made of rubber materials) and a liquid filling main pipe 31. The main liquid injection pipe 31 is a rigid pipe, and the top of the main liquid injection pipe 31 is communicated with the intermediate communication part 2. The liquid injection hose 32 is provided between the liquid injection main pipes 31. The two ends of the connecting sleeve 33 are fixed on the liquid injection main pipe 31 at the two ends of the liquid injection hose 32. By providing the liquid filling hose 32 on the liquid filling pipe 3, when the air pressure in the transit communication portion 2 is low, the liquid filling hose 32 is contracted, resulting in a reduction in the inner diameter of the liquid filling hose 32. Therefore, when the steel ball 8 enters the transfer communication part 2 from the automatic steel ball feeding part 6 (at this time, the transfer communication part 2 is in a low-pressure transfer state), the shrinkage deformed liquid injection hose 32 can prevent the steel ball 8 from directly entering the automobile suspension part 7 along the liquid injection pipe 3. After the automobile suspension part 7 finishes injecting the liquid, the air pressure value in the transfer communication part 2 is increased and restored at the moment, and meanwhile, the liquid injection hose 32 which is originally contracted and deformed is restored to the original shape, so that the steel ball 8 can smoothly enter the automobile suspension part 7 through the liquid injection hose 32 to seal the automobile suspension part 7. Therefore, by arranging the liquid injection hose 32, the time for throwing the steel ball 8 can be automatically controlled, when the incomplete injection of liquid into the automobile suspension part 7 occurs, the steel ball 8 enters into the automobile suspension part 7 to prevent the liquid from entering, the mesh screen type valve in the transfer communication part 2 is replaced, and the whole structure is simplified.
Meanwhile, by arranging the connecting sleeve 33, the liquid injection hose 32 can not influence the liquid injection pipe 3 to be inserted into the liquid injection hole of the automobile suspension part 7 under the driving of the lifting device.
6-7, in one embodiment, the outer circumference of the cross-section of the filler hose 32 is oval such that the wall thickness on the left and right sides of the filler hose 32 is greater than the wall thickness on the front and rear sides. When the air pressure value in the transfer communication part 2 is lower, at this time, the front side and the rear side of the liquid injection hose 32 are inwards bent and contracted, at this time, the steel ball 8 is blocked by the liquid injection hose 32, and the liquid injection hose 32 after contraction deformation still can convey liquid through annular areas on the left side and the right side, so that the steel ball 8 is blocked and meanwhile the liquid is not blocked from entering the automobile suspension part 7.
In one embodiment, the bottom of the main injection pipe 31 is provided with a small hole section, and the inner diameter of the small hole section is the same as the diameter of the steel ball 8. Through being provided with the aperture section in annotating liquid main pipe 31 bottom for when steel ball 8 falls into in the aperture section, laminating closely between steel ball 8 and the aperture section, at this moment, only need vacuum tube 4 to the centre in-communication portion input atmospheric pressure, can make steel ball 8 enter into the notes liquid downthehole of car suspension member 7 with higher speed under the effect of atmospheric pressure, make notes liquid downthehole prop greatly and warp respectively, make notes liquid downthehole sealed.
In one embodiment, the tooling 1 clamps the main spring elastomer of the stationary automotive suspension 7. The main spring elastomer portion of the car suspension 7 is thicker than at other locations, and therefore, the car suspension 7 is less prone to damage when the tool 1 clamps it.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
