This relatively low, the higher shock resistance of whole fixture and good wearability, solving traditional machine tool fixture, easily shake is altered, machining accuracy
The shortcomings that can not improving.
Brief description of the drawings
Fig. 1 is the structural representation of high precision machine tool fixture of the present invention；
Fig. 2 is the structural representation of wear-resisting chuck in high precision machine tool fixture of the present invention.
Wherein, 1 is front pressuring plate, and 2 be locating rod, and 3 be foam damping core, and 4 be granolith covering, and 5 be casting mark.
Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
A kind of structure of high precision machine tool fixture of the present invention as depicted in figs. 1 and 2, including wear-resisting chuck, foam damping
Core 3 and granolith covering 4, the wear-resisting chuck include front pressuring plate 1 and are arranged on the locating rod 2 of the rear end of front pressuring plate 1,
Be provided with positioning hole on the foam damping core 3, the locating rod 2 inserts the positioning hole, the granolith covering 4 with
The wear-resisting chuck, foam damping core 3 casting be integrated, the granolith covering 4 encase the foam damping core 3 and with
The front pressuring plate 1 is fixedly linked.
In the present embodiment, the material of the front pressuring plate 1 is Cr12 mould steel.
In the present embodiment, the locating rod 2 has more, the positioning hole have it is multiple, the multiple positioning hole with it is multiple
Locating rod 2 corresponds.
In the present embodiment, the foam damping core 3 is L-shaped.The upper end of in general fixture is main stress point, is being used
During fixture upper end stress it is larger.Foam damping core 3 is designed into l-shaped, the energy that can withstand forces the upper end of fixture
Power is bigger.Fixture lower end is either during being fixedly clamped simultaneously, or the power that it is subject to during cutting is processed
It is all smaller.Shock resistance can be improved while proof strength using longer foam damping core, and save material.
In the present embodiment, the locating rod 2 is provided with casting mark 5.Set casting mark 5 conveniently production can make
Make.
The method for producing high precision machine tool fixture of the present invention is as follows：
Carried out successively according to following steps：
1) after selecting the wear-resisting chuck of Cr12 mould steel makings, the wear-resisting chuck to include front pressuring plate 1 and be arranged on front pressuring plate 1
The locating rod 2 at end；
2) foam damping core 3 is made using plastic foam injection machine, the foam damping core 3 is provided with positioning hole；
3) the casting slurry of making artificial granite covering 4, the casting slurry is by resin, curing agent, diluent, quartz
Sand filler and granite aggregate mix, and casting slurry includes resin 160-240g, curing agent 40-50g described in per 1000g,
Diluent 20-30g, quartz sand filler 280-380g, granite aggregate 300-500g；
4) mould is made, the shape of the mold stamper is consistent with jig to be manufactured；
5) electromagnetic type shaking device is selected, mould is fixed on the bumper of the electromagnetic type shaking device and will be wear-resisting
