In the technique scheme, the faying face of said driving wheel and nut is taper seat.Through above-mentioned
Structure, the setting angle of each driving wheel does not have specific requirement, is convenient to the installation of chain.Simultaneously, divide
Do not adjust the height and position of 3 elevating levers continuously, thereby the depth of parallelism of dish seat is gone up in adjustment.
In the technique scheme; Said guide rail is provided with the rotary encoder that is used to detect the lowering or hoisting gear position, detects the rotating cycle of drive sprocket, is convenient to accurately control the position of lowering or hoisting gear on guide rail; Be right against the below of station when making its work, prevent the dislocation of upper and lower dish seat; Said brace summer is provided with and is used to detect the rotary encoder that the dish seat is put, and through measuring the rotating cycle of nut, can accurately calculate the position of dish seat, thereby regulate rim width.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1. the shared lower wall seat lifting and lowering mechanism of multistation of the present invention, simple in structure, volume is little, is convenient to install.
2. each station flush system of the present invention need not be provided with switching mechanism side by side in the side of column, and station does not need upset, running safety.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment one: referring to Fig. 1 ~ Fig. 5 and shown in Figure 7; Aeration settling device behind a kind of tire comprises column and 4 stations, is fixed with H shape brace summer on the said column; 4 stations become the 2*2 array to be arranged at 4 foots of H shape brace summer, and the transverse arm of said brace summer is fixedly connected with column.
The two trailing arms below of H shape brace summer is respectively equipped with the straight line guide rail; 1; Be slidingly equipped with the lowering or hoisting gear that control lower wall seat goes up and down on this guide rail 1; Said lowering or hoisting gear comprises the gripper shoe 3 that drives cylinder 2, is fixed on the cylinder rod output, and said gripper shoe 3 constitutes detachable the connection through snap-in structure with the lower wall seat.
The lower end of said lower wall seat is a cylindrical boss; Offering cross section on this boss periphery is semicircular annular groove; The upper end of said snap-in structure offers the counterbore that cooperates with said boss external diameter; And the upper end of this snap-in structure offers pin-and-hole corresponding to the position of said groove, said snap-in structure through groove, pin-and-hole and be plugged in cylinder plugs in this pin-and-hole and the groove realize with the lower wall seat between detachable the connection.
Said lowering or hoisting gear comprises that also branch occupy two pilot holes 4 that drive cylinder 2 left and right sides and be fixedly connected with the driving cylinder block; Be embedded with linear bearing 40 in the pilot hole 4; Guide post 5 is smooth and easy slip in the endoporus of linear bearing 40, and the upper end of each said guide post 5 is fixedly connected with gripper shoe 3.
Be provided with transverse slat between the upper end of two said pilot holes 4, be installed with cushion pad 8 on the said transverse slat, the upper end of cushion pad 8 was butted on the lower surface of gripper shoe 3 when gripper shoe 3 was positioned at extreme lower position, received greater impact power when avoiding lowering or hoisting gear to reduce to extreme lower position.
As shown in Figure 3; The two ends of each bar guide rail 1 are respectively equipped with a driven sprocket 7; The below, middle part of guide rail 1 is provided with servomotor 15 and the drive sprocket that is fixedly connected with motor shaft 6, is provided with between the master and slave sprocket wheel along the driving-chain of this guide rail running, and said lowering or hoisting gear is fixed on the said driving-chain.Servomotor 15 can be controlled the stop position of lowering or hoisting gear on driving-chain very accurately.
Said guide rail 1 is provided with the rotary encoder that is used to detect the lowering or hoisting gear position, detects the rotating cycle of drive sprocket, is convenient to accurately control the position of lowering or hoisting gear on guide rail, is right against the below of station when making its work, prevents the dislocation of upper and lower dish seat.
As shown in Figure 6; The dish seat of going up of said station is fixedly connected with drive unit; Said drive unit comprises 3 external screw thread elevating levers 9 of evenly arranging being connected with last dish seat, is bolted in elevating lever nut outside 10, and said nut 10 is axially fixed on the brace summer through syndeton.
