The utility model content
Technical problem to be solved in the utility model provides a kind of bloated deduction, satisfies it with the radial distance that guarantees the automobile flexible joint two-port and is connected matching requirements between automobile engine and the blast pipe, improves part quality.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of bloated deduction is characterized in that, comprises support, this support is provided with the interior bloated chuck of concentric and withholds chuck, the chuck that should interiorly expand is connected with first drive unit by the first piston bar, and under the effect of this first drive unit, entad can do or centrifugal motion; This is withheld chuck and is connected with second drive unit, and under the effect of this second drive unit, entad can do or centrifugal motion; Should in expand chuck and withhold and form the annular gap between the chuck, the position of withholding of workpiece is arranged in this space.
The chuck that expands in described is a collet.
The chuck inner surface that expands in described is frustum, and outer surface is cylindrical; Described first drive unit comprises first piston and first piston bar; One end of this first piston bar is connected with first piston, and other end outer surface is frustum, and the shape of this frustum and interior bloated chuck inner surface is suitable, is positioned at the inboard of the chuck that expands.
The described chuck outer face of withholding is frustum, and inner face is cylindrical; Described second drive unit comprises second piston, second piston rod and tapered sleeve; One end of this second piston rod is connected with second piston, and the other end is connected with tapered sleeve, tapered sleeve with withhold chuck and flexibly connect; And, in the tapered sleeve with withhold the surface that chuck is connected and be frustum, suitable with the shape of withholding the chuck outer surface.
Adopt technique scheme, utilize first drive unit to drive the interior chuck that expands and expand outwardly, the bellows in the automobile flexible joint outwards can be out of shape, enlarge the internal diameter of bellows.Utilizing the drive of second drive unit to withhold chuck moves inward, can be with the whole inwardly extruding of the protecting wire net circle in the automobile flexible joint, to dwindle the internal diameter of protecting wire net circle, and then the end integral body of automobile flexible joint compressed, reach winding pipe, bellows, outer net and the close-connected purpose of protecting wire net circle in the flexible hinge end.By the interior outer button that expands, when automobile flexible joint and adapter welding, good welding performance is not prone to the welding leakage phenomenon.
Description of drawings
Fig. 1 is the structural representation of automobile flexible joint.
Fig. 2 is a cross-section front view of the present utility model.
Among the figure, 1, first piston, 2, second piston, 3, second piston rod, 4, tapered sleeve, 5, withhold chuck, 6, interior bloated chuck, 7, the first piston bar, 8, winding pipe, 9, bellows, 10, outer net, 11, the protecting wire net circle.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 1, the workpiece automobile flexible joint generally is made up of winding pipe 8, bellows 9, outer net 10 and 11 4 parts of protecting wire net circle.The port of automobile flexible joint has aforementioned four layer materials.During with the adapter welding, two ports of automobile flexible joint are connected between automobile engine and the gas extraction system.
As shown in Figure 2, a kind of bloated deduction of the present utility model comprises support, and this support is provided with the interior bloated chuck 6 of concentric and withholds chuck 5.The interior chuck 6 that expands is collet or other elastomer chucks.The chuck 6 that should interiorly expand is connected with first drive unit by first piston bar 7, and under the effect of this first drive unit, entad can do or centrifugal motion; This is withheld chuck 5 and is connected with second drive unit, and under the effect of this second drive unit, entad can do or centrifugal motion; Should in expand chuck 6 and withhold between the chuck 5 and form the annular gap, the position of withholding of workpiece is arranged in this space.Wherein, the inner face of withholding chuck 5 can be step-like, wherein equals the width of the protecting wire net circle 11 of automobile flexible joint near the step width of withholding chuck 5 axis.The course of work of this device is the chuck 6 and withhold place, annular gap between the chuck 5 of expanding in earlier the port of automobile flexible joint being placed on, start drive unit then, the chuck 6 that expands in first drive unit makes outwards moves, second drive unit makes to be withheld chuck 5 and moves inward, thereby finish working procedure, make the internal diameter of automobile flexible joint port reach matching requirements the interior outer button that expands of automobile flexible joint port.
As a kind of optimal way, the inner surface of interior bloated chuck 6 is frustum, and outer surface is cylindrical.First drive unit comprises first piston 1 and first piston bar 7.One end of this first piston bar 7 is connected with first piston 1, and other end outer surface is frustum, and the shape of this frustum and interior bloated chuck 6 inner surfaces is suitable, is positioned at the inboard of the chuck 6 that expands.Like this,, can realize the extruding of chuck 6 of expanding in 7 pairs on the first piston bar, thereby expand chuck 6 in realizing outwards or inwardly motion by the control of 1 pair of first piston bar 7 of first piston.In Fig. 2, when first piston bar 7 levels during to left movement, interior bloated chuck 6 is outwards done to expand to move, thereby the port of extruding automobile flexible joint makes the internal diameter of the port that is positioned at automobile flexible joint enlarge.When first piston bar 7 levels moved right, interior bloated chuck 6 moved inward under elasticity own or the effect at connected elastomeric element, and the internal diameter of interior bloated chuck 6 diminishes.
As another kind of optimal way, to withhold chuck 5 outer faces and be frustum, inner face is cylindrical.Second drive unit comprises second piston 2, second piston rod 3 and tapered sleeve 4.One end of this second piston rod 3 is connected with second piston 2, and the other end is connected with tapered sleeve 4, tapered sleeve 4 with withhold chuck 5 and flexibly connect.In the tapered sleeve 4 with withhold the surface that chuck 5 is connected and be frustum, suitable with the shape of withholding chuck 5 outer surfaces.Like this, the control by 2 pairs second piston rods 3 of second piston can realize moving horizontally of tapered sleeve 4, withholds chuck 5 inside or outwards motions thereby drive.In Fig. 2, when tapered sleeve 4 levels move right, withhold chuck 5 and inwardly move, thus the port of extruding automobile flexible joint, feasible four layers of parts that are positioned at the port of automobile flexible joint closely contact.When tapered sleeve 4 levels during, withhold chuck 5 outwards motion under the effect of elastomeric element, away from automobile flexible joint to left movement.
Protection domain of the present utility model is not limited to above-mentioned specific embodiment; the chuck 6 and withhold between the chuck 5 and form the annular gap as long as expand in can being implemented in, and realize between the two getting final product near the entad motion of axis with away from the centrifugal motion of axis by drive unit.
