When push rod with after the workpiece end cap contacts, the ball bowl is pressed into ball seat, the pressure-bearing module has backward displacement simultaneously, push rod with ball bowl, end cap dieback after, the pressure-bearing module remains unchanged the push rod position and the main shaft of riveter can drive roller rotation and walk downward, finally revolve die and the ball seat turn-up portion is divided carry out machining deformation, finish the ball stud sealing.Therefore can realize ball stud is press-fited and these two kinds of process integrations of roll riveting are finished continuously to a technique.
If revolve on the main shaft that die appends to riveter compound, then ball stud is press-fited and these two kinds of process integration to machines of roll riveting are finished continuously.
For avoiding push rod also to rotate, above the pressure-bearing module, add a plane bearing, make push rod remain static.
Need a large amount of connectors between automotive wheel and chassis, in order to satisfy the requirement of rotation in the Vehicle Driving Cycle process and bob, vibration, ball stud becomes a part indispensable in the Automobile Chassis Parts.Along with constantly popularizing that human automobile uses, the demand of ball stud also will improve constantly.Obviously, pressure and these two kinds of techniques of riveting are integrated in the ball stud assembly technology will further be promoted.
Description of drawings
Fig. 1, Fig. 2 are respectively the schematic diagram that existing car ball stud press-fits, revolves the riveting assembly technology.
Fig. 3 is riveter overall schematic of the present invention.
Fig. 4 is the compound structural representation that revolves die of the present invention.
The specific embodiment
The shaft portion that revolves die among Fig. 4 has carried out partly cuing open, so that show its internal structure.As shown in Figure 3 and Figure 4, in one embodiment of this invention, the compound die 4 that revolves comprises and revolves die 41, push rod 42, pressure-bearing module 43 and plane bearing 44.Revolve die 41 and can select the die that revolves of existing riveter, it is used for ball stud is revolved the riveting assembling, the ball seat turn-up portion is divided carry out machining deformation, reaches the effect of ball stud sealing.The axial region that revolves die 41 has axial centre bore 412, and push rod 42 is inserted in the centre bore 412, and its top (lower end) is outer to be exposed at outside the centre bore 412, and its cardinal extremity (upper end) and pressure-bearing module 43 are joined.Pressure-bearing module 43 is elastic module in embodiment as shown in the figure, can directly adopt block rubber.End in contrast to push rod 42 of pressure-bearing module 43 is equipped with plane bearing 44, and plane bearing 44 plays the effect of transmitting axial force on the one hand, cuts off on the one hand transfer of torque.Wholely compoundly revolve the upper end of die 4 and the main shaft of riveter joins, the two can connect by flange, and main shaft contacts with plane bearing 44, plane bearing 44 is played the effect of supporting.Plane bearing 44 can adopt annular spherical guide, but the implication of plane bearing 44 is not limited to the spherical guide of annular, and it refers to transmit axial force but the bearing that can cut off moment of torsion.
Embodiment as shown in the figure compound revolved die when work, drives push rod 42 when axis feeding, when push rod 42 with after the workpiece end cap contact, by main shaft pressure the ball bowl is pressed into ball seat, this moment pressure-bearing module 43 to be that block rubber is existing partly be out of shape.Push rod 42 with ball bowl, end cap dieback after, block rubber continues distortion, push rod 42 positions remain unchanged and main shaft continues to drive roller 410 rotations and walks downward.This moment, plane bearing 44 was that the ball rotation of annular spherical guide makes push rod remain static in order to avoid push rod also to rotate.Finally revolve die and the ball seat turn-up portion is divided carry out machining deformation, finish the ball stud sealing.
In another embodiment of the present invention, the mainshaft mechanism of push rod 42 and riveter can separate and moves, and also can reach purpose of the present invention.Be executing agency at axis hole 412 or push rod 42 inner annex solution pressing systems such as pressure-bearing module 43, the dynamic change of the hydraulic coupling that provides by hydraulic pressure, pressure-bearing module 43 drives push rod 42 axially having certain displacement thereupon.
Car ball stud of the present invention press-fits and revolves the riveting Applying Compound Assembling Technology and can understand in conjunction with embodiment as shown in the figure, at first ball pin and ball bowl, end cap is successively placed in the ball seat, and the decline power source of push rod 42 is exactly the riveter main shaft.The inner flexible member (for example block rubber) 43 that adds of push rod, a pair of annular spherical guide 44 is placed in block rubber 43 upper surfaces.When the riveter main shaft descended, push rod 42 descended and simultaneously with after the end cap of workpiece contacts, block rubber 43 compressive deformations.Along with the continuous increase of slippage, push rod 42 pressure force end cap and ball bowl slowly to be pressed in the ball seat.Main shaft continues to walk downward afterwards, thereby makes push rod 43 complete diebacks owing to the ball bowl kills in ball seat this moment.At block rubber constantly under the effect of distortion, roller 410 divides with the ball seat turn-up portion smoothly and contacts and push rod 42 holding positions are constant.Roller 410 may drive push rod block rubber base and rotate together in rotary course, so add annular spherical guide 44, the ball rotation makes the push rod transfixion, finally realizes the ball stud sealing.
By transforming the existing riveting equipment that revolves, can be by the feeding of main shaft, ball stud is press-fited and these two kinds of process integration to machines of roll riveting are finished continuously, greatly reduce the consumption of the expense of equipment investment and manpower, the energy.
