Description
Technical field
The utility model relates to plastic vibratory Friction welding technique fields, especially a kind of to be used for linear oscillator friction welding
The lifting platform of machine.
Background technique
Linear oscillator friction welding (FW) is the principle based on friction welding (FW) and a kind of welding technique newly developed, has become many at present
The preferred welding procedure of field plastic product, for car light welding, since Vibration welding flash is few, welding interval is short,
Relative to hot plate welding, production efficiency is substantially increased.The theoretical basis of Vibration welding is that friction causes to vibrate and generate
Heat.Make two plastic parts for needing to weld, keep certain pressure to compress, vibrate one of them, makes it with respect to another weldment
Shift reciprocately movement is done, by the frictional heat generation between contact surface, when temperature, which rises to, to be enough to melt weldment, stops fortune
It is dynamic, continue cure under pressure, the welding process recombined between upper and lower plastic part molecule is made to be known as linear oscillator friction welding skill
Art.
Linear oscillator friction welding machine currently used in the market, no matter model all includes with lower component: in rack, rack
Lifting platform, vibration component and mold, wherein the bottom elevation platform in rack is used to place and more mold exchange, it is mainly by one
Metal platform composition.In the case where needing to be replaced frequently mold, due to the planar friction between mold and platform, lead to mold
Bottom and platform surface serious wear, it is difficult that result not only results in mold changing, and can seriously affect the positioning accuracy of mold.
Utility model content
To solve difficult mold changing existing for linear oscillator friction welding machine currently used in the market and mold and lifting
The problem of table top damages, the utility model provides a kind of lifting platform for linear oscillator friction welding machine.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of lifting platform for linear oscillator friction welding machine, it includes hoistable platform, the intermediate aperture of hoistable platform,
The tapping is equipped with mold changing supplementary structure；It changes the mold and multiple universal bearings is housed on the surface of supplementary structure, and change the mold auxiliary knot
Structure makees elevating movement by cylinder.
Further, the opening of hoistable platform is equipped with limited step；Change the mold the underrun limit after supplementary structure rises
Position step is flushed with the surface of hoistable platform.
The utility model has the advantages that
1. the frictional force of mold and lifting platform, reduces when the utility model can reduce the mold changing of linear oscillator friction welding machine
The degree of difficulty of mold changing.
2. the abrasion of mold and lifting platform, improves mould when the utility model can reduce the mold changing of linear oscillator friction welding machine
Has the service life, to increase mold positioning accuracy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the lifting platform entirety of an embodiment of the present invention；
Fig. 2 is the front section view of the lifting platform of an embodiment of the present invention；
In figure: 10- hoistable platform, 101- limited step, 20- mold changing supplementary structure, 201- universal bearing, 202- cylinder,
30- guide post, 40- weld mold.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
The present embodiment proposes a kind of lifting platform for linear oscillator friction welding machine, as shown in Figure 1, it includes that lifting is flat
Platform 10, the intermediate aperture of hoistable platform 10, the tapping are equipped with mold changing supplementary structure 20；On the surface for changing the mold supplementary structure 20
Equipped with multiple universal bearings 201.As shown in Fig. 2, mold changing supplementary structure 20 makees elevating movement by cylinder 202；Hoistable platform 10
Opening be equipped with limited step 101；This lifting platform is connect by guide post 30 with linear oscillator friction welding machine, and can be upper and lower
Lifting.
In the present embodiment, it is placed on universal bearing 201 when weld mold 40 loads and unloads, avoids planar friction bring
Damage, while being convenient for the running fix on platform of weld mold 40.The opening of hoistable platform 10 has limited step 101, makes to change
After mould supplementary structure 20 rises, the bottom surface of mold changing supplementary structure 20 is flushed with the surface of hoistable platform 10.The platform of hoistable platform 10
There are mold location hole and lock to pay on face and uses threaded hole.
The present embodiment is in use, mold changing supplementary structure 20 rises, due to the effect of limited step 101, mold changing supplementary structure
20 bottom surface is flushed with the surface of hoistable platform 10.After weld mold 40 to be pushed into the anchor point of hoistable platform 10, mold changing auxiliary
Structure 20 declines, locking die 40, completes upper mold.When mould unloading, weld mold 40 is unclamped, mold changing supplementary structure 20 rises, will weld
It connects mold 40 and releases hoistable platform 10, complete mould unloading.
Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model
On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists
Within the protection scope of the utility model.
