Description
[technical field]
The relevant a kind of inverse jig of the utility model is meant a kind of inverse jig that magnesium-alloy material is produced that is applied to especially.
[background technology]
Be the lightest metal in practical metal, the proportion of magnesium approximately is 2/3 of aluminium, is 1/4 of iron.It is the lightest metal in the practical metal.Magnesium alloy is widely used in portable apparatus and the automobile industry, reaches light-weighted purpose.Magnesium alloy has high strength, high rigid characters, though the proportion of magnesium alloy is heavier than plastics,, the intensity of Unit Weight and spring rate are than plastics height, so under the situation of same intensity parts, it is thin and light that the parts of magnesium alloy can be done than plastics.In addition, because therefore the specific strength of magnesium alloy, under the intensity that does not reduce parts, can alleviate the weight of the parts of aluminium or iron also than aluminium alloy and iron height.Magnesium alloy has the characteristics of good thermal conduction, though the thermal conductivity factor of magnesium alloy not as good as aluminium alloy,, exceed tens of times than plastics, therefore, used for magnesium alloy can be effectively be dispersed into the outside with the heat of inside on electric equipment products.Magnesium alloy has the good characteristics of electromagnetic wave shielding performance, and therefore the electromagnetic wave shielding performance of magnesium alloy, uses magnesium alloy can save the electroplating work procedure of electromagnetic shielding film than electroplate the effective of screened film on plastics.The good magnesium alloy of machining property is littler than the cutting resistance of other metal, when machining, and can fast speeds processing.Therefore, magnesium alloy is just obtaining increasingly extensive application in fields such as auto industry, communications electronics industry and aerospace.Magnesium alloy output up to 20%, demonstrates great application prospect in the annual growth in the whole world in recent years.
The clamping fixture that the processing of magnesium-alloy material is used adopts the mode of just pressing from both sides at present.See also Fig. 1, it illustrates and is the positive clamp tool of the magnesium alloy of prior art.As shown in the figure, this tool comprises a base plate 4, which is provided with plurality of support columns 3, and these support column 3 tops are provided with a fixed head 5, and all are provided with one or several rotary cylinders 2 in each side of fixed head 5.Product 1 is fixed on the fixed head 5, does clamping by rotary cylinder 2 again, when take out product 1 then these rotary cylinders 2 rise and rotate, thereby make product 1 and its disengaging.
Yet, for above-mentioned tool, need to use a large amount of cylinders 2 to do clamping, because by several cylinder 2 clampings, there is the clamping problem of unstable, and,, need to use cutter to mill owing to have working position 6 on the product 1 for product 1, because magnesium alloy elasticity is better, working position 6 clamping instabilities cause tool damage easily, and have reduced the accurate to dimension of product 1, and then reduce the yield of product 1.
In view of this, be necessary to develop a kind of inverse jig in fact, thereby reduce the number of cylinder, and can reduce the infringement that adds tool setting in man-hour tool, improve the accurate to dimension of product, thereby reach the raising of product yield.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of inverse jig, thereby reduces the number of cylinder, and can reduce the infringement that adds tool setting in man-hour tool, improves the accurate to dimension of product, thereby reaches the raising of product yield.
For reaching above-mentioned purpose, inverse jig of the present utility model is done further processing in order to the clamping magnesium-alloy material, and this structure comprises:
One base plate which is provided with plurality of support columns, and its middle position or close middle position are provided with a cylinder;
One top board, this top board and said cylinder top are fixed, and movable being sheathed on above-mentioned each support column;
One clamping plate, these clamping plate are fixed at above-mentioned each support column top.
Preferably, above-mentioned top board is parallel with clamping plate, so can make things convenient for the clamping of product.
Preferably, above-mentioned top board also is provided with several basic fixed position pieces near clamping plate one side, in order to the basic fixed position to product.
Preferably, above-mentioned top board also is provided with one or several side locating pieces near clamping plate one side, in order to product is done further location, prevents that product from moving in the horizontal direction.
Preferably, above-mentioned top board also is provided with one or several back-up blocks near clamping plate one side, does support in order to the corresponding site to product.
Preferably, above-mentioned clamping plate are provided with one or several and penetrate the working groove of these clamping plate, in order to see through these working grooves product are done processing.
Compared to prior art, inverse jig of the present utility model, the magnesium-alloy material that to do further processing by the rising of cylinder is held between top board and the clamping plate, answer by cylinder, conveniently put into or take out magnesium-alloy material, reduced the number of cylinder, and can reduce the infringement that adds tool setting in man-hour tool, improve the accurate to dimension of product, thereby reach the raising of product yield.
For the purpose of this utility model, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
