Embodiment
With reference to specific embodiments and the drawings, the utility model is described in further detail, elaborates in the following description
More details are in order to fully understand the utility model, but the utility model obviously can be different from what this was described with a variety of
Other manner is implemented, and those skilled in the art can be in the case of without prejudice to the utility model connotation according to practical application feelings
Condition is made similar popularization, deduced, therefore should not limit the scope of protection of the utility model with the content of this specific embodiment.
It should be noted that Fig. 1 to Fig. 6 d only as an example, its not be according to equal proportion condition draw, and
And it should not be construed as limiting in this, as the protection domain to the utility model actual requirement.
As shown in figure 4, the invention discloses a kind of connection press-loading device 4 with floating junction device 6.Connection press fitting is set
Standby 4 are used to be pressed workpiece 5, including pedestal 1, press-loading device 2 and workpiece grip mechanism 3, press-loading device 2 include pressing machine
Frame 201, aligning guide 203 and pressure head 202, press fitting frame 201 can be c-type frame, and aligning guide 203 and pressure head 202 are set
In the upper and lower ends of press fitting frame 201, and keep aligning, the meaning for keeping aligning is so that aligning guide 203 and pressure head 202
Coaxial line.
Workpiece 5 is placed on workpiece grip mechanism 3 and clamped fixation.Workpiece 5 has press mounting hole 501, due to manufacturing reason,
Workpiece 5 is probably the bending as shown in Fig. 5 a to 5d, so as to cause pressure head 202 and press mounting hole 501 not to align, pressure head 202
On press-in piece 502 can not also be aligned with press mounting hole 501, certain misalignment angle (as shown in G in Fig. 5 a) be present, cause to be pressed into
Part 502 is easily damaged.
Workpiece 5 by workpiece grip mechanism 3 due to being clamped, and it is fixed to be commonly angled relative to pedestal 1, can not be rotated, therefore, such as
Fruit needs pressure head 202 and press mounting hole 501 to align, then needs to make press fitting frame 201 move (as shown in Figure 5 b), work as aligning guide
203 realize to timing with press mounting hole 501, and pressure head 202 also just aligns with the realization of press mounting hole 501, the press-in piece 502 on pressure head 202
Also realize and align with press mounting hole 501.It can be that press mounting hole 501 gives aligning guide 203 to be pressed the power resources that frame 201 is moved
Reaction force.
To realize the motion of press-loading device 2, the connection of press-loading device 2 and pedestal 1 is floating connection, such as can use bullet
Spring connects press-loading device 2 and pedestal 1, but spring is in removal external load, can be vibrated repeatedly in equilbrium position, it is necessary to compared with
The long time could stop, and have a strong impact on the press fitting efficiency of press-loading device 4.Therefore, in one embodiment of the present utility model
In, as shown in figure 4, connecting press-loading device 2 and pedestal 1 using floating junction device 6, floating junction device 6 includes elastic rubber
Glue body 60, the first connector 61 and the second connector 62.One end of first connector 61 is fixedly installed on elastic caoutchouc body
In 60, the other end is used to be fixedly connected with pedestal 1, and one end of the second connector 62 is fixedly installed in elastic caoutchouc body 60,
The other end is used to be fixedly connected with press-loading device 2.The press fitting frame 201 of press-loading device 2 includes connecting plate 201a, the second connector
62 are fixedly connected with connecting plate 201a.
Floating junction device 6 can be manufactured by die press technology for forming.Specifically, the first connector 61 and the second connector
62 are placed in mould, then the pouring liquid slurry in mould, then carry out pressurize, heating vulcanization, slurry and the first connector 61
An entirety is solidified into the second connector 62, it is possible to is opened mould and is taken out finished product.Floating junction device 6 can be it is multiple and
It is arranged symmetrically, such as four, rectangular distribution.
With continued reference to Fig. 5 b, the power resources that press fitting frame 201 is moved can be that press mounting hole 501 gives aligning guide 203
Reaction force.For example, aligning guide 203 may include a telescopic locating shaft (accompanying drawing is not shown).Locating shaft all the time with
Pressure head 202 keeps aligning.Locating shaft enters press mounting hole 501 when stretching out, and is contacted with the inwall of press mounting hole 501.If pressure head 202 and press fitting
Hole 501 does not align and misalignment angle be present, because workpiece 5 keeps fixing, so locating shaft can produce when stretching out to press mounting hole 501
A raw active force, press mounting hole 501 will produce a reaction force to locating shaft, and reaction force causes press-loading device to produce work
Load for floating junction device.Elastic caoutchouc body bears to load and produce deformation, to enable press-loading device 2 relative
Moved in workpiece 5, press fitting frame 201 causes locating shaft towards making locating shaft realize that the direction aligned is moved with press mounting hole 501
Can extend into press mounting hole 501, and shaft hole matching realized with press mounting hole 501, realizes so as to aligning guide 203 and pressure head 202 and
Press mounting hole 501 aligns.
As shown in Figure 5 c, after aligning, pressure head 202 will be pressed into part 502 and be pressed into press mounting hole 501.As fig 5d, it is pressed process
After end, locating shaft can exit out of press mounting hole 501, and press mounting hole 501 disappears to the reaction force of locating shaft, is pressed frame
201 initial positions replied in the presence of elastic caoutchouc body 60.
Reaction force in addition to being transmitted by locating shaft, can the transmission in the form of magnetic force, such as aligning guide 203 can
To be a magnetic force aligning guide, magnetic force aligning guide produces magnetic force, and magnetic force attracts workpiece 5 so that press mounting hole 501 is to aligning machine
Structure 203 produces reaction force.After installation process terminates, reaction force disappears, work of the press fitting frame 201 in elastic caoutchouc body 60
Initial position is returned under.Aligning guide 203 keeps phase to timing, press fitting frame 201 with press mounting hole 501 with press mounting hole 501
To static.The judgement whether aligning guide 203 aligns with press mounting hole 501 can also be realized by setting light sensor.
Because the damping of elastic caoutchouc body 60 is larger, compared to spring, elastic caoutchouc body 60 after unloading, Neng Gougeng
Settle out soon, be returned to initial position.The process that elastic caoutchouc body 60 deforms upon is as shown in Fig. 3 a to 3d.Fig. 3 a are
