Abstract
The invention discloses a clamp of a high-frequency filter cover plate, comprising a body, a processing position corresponding to the high-frequency filter cover plate and three screw positioning holes, wherein the three screw positioning holes is arranged on the body and are non-collinear; the thickness of the body is at least 20mm; the clamp of the high-frequency filter cover plate fully applies the principle of three-point positioning, three points determine a plane, each supporting point is also a pressing point of each screw, therefore, the influence of the planeness of a supporting plane can be eliminated when one plane is processed, and the planeness can achieve the effect of stepwise depletion; the change of the planeness can be within 0.10 in the first step, 0.05 in the second step and 0.025 in the third step; as long as the planeness is within 0.025, the straightness of the length direction of a workpiece is less than 0.02, and the straightness of the width direction thereof is less than 0.01; therefore, the clamp can guarantee the qualification rate of products.
Description
Technical field
The present invention relates to a kind of anchor clamps, refer in particular to a kind of anchor clamps of high-frequency filter cover plate, belong to the frock clamp field of engineering technology.
Background technology
In the prior art, 1), the roughing of B face (surplus, monolateral 0.3mm the high accuracy processing method of aluminium alloy cover plate face:; Anchor clamps, vice clamps, manually-operated); 2), disposable the putting in place of the thick fine finishining of A face (during roughing, monolateral surplus 0.15mm, end face made allowance 0.1mm, backmost the milling cutter finish-milling puts in place; Anchor clamps, vice clamps, manually-operated); 3), (first side mills and puts in place the fine finishining of B face, and end face mills and puts in place again; Anchor clamps, special fixture, steam-operating control); In process of the test, we find the linearity of product, thickness is very unstable, product qualified rate is very low.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: the anchor clamps that proposed the high high-frequency filter cover plate of a kind of product qualified rate.
Technical solution of the present invention is achieved in that a kind of anchor clamps of high-frequency filter cover plate, comprise body, with the corresponding machining position of high-frequency filter cover plate, 3 screw locating holes, described screw locating hole is provided with on the body, not conllinear; Can not be subjected to the influence of the flatness of supporting surface like this in face of processing, flatness can reach the effect of progressively successively decreasing.
Preferably, the thickness of described body 20mm at least.
The anchor clamps of the present invention program's high-frequency filter cover plate, this sub-folder tool has used the principle of three-point fix fully, determine a plane at 3, each strong point also is compressing a little of screw, can not be subjected to the influence of the flatness of supporting surface like this in face of processing, flatness can reach the effect of progressively successively decreasing; The variation of flatness can reach in the first step 0.10, in second step 0.05, in the 3rd step 0.025, and as long as flatness 0.025 with the linearity of the length direction of interior workpiece also necessarily less than 0.02, the linearity of short direction is less than 0.01; Can guarantee the qualification rate of product like this.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the front view of high-frequency filter cover plate of the present invention;

Wherein: 1, body; 2, screw locating hole; 3, machining position.
The specific embodiment
Shown in accompanying drawing 1,2, high-frequency filter cover plate of the present invention.
As shown in Figure 3, the anchor clamps of a kind of high-frequency filter cover plate of the present invention, comprise body 1, with 3,3 screw locating holes 2 of the corresponding machining position of high-frequency filter cover plate, described screw locating hole is provided with on the body, not conllinear; Can not be subjected to the influence of the flatness of supporting surface like this in face of processing, flatness can reach the effect of progressively successively decreasing; The thickness of described body is 20mm at least.
The anchor clamps of the present invention program's high-frequency filter cover plate, this sub-folder tool has used the principle of three-point fix fully, determine a plane at 3, each strong point also is compressing a little of screw, can not be subjected to the influence of the flatness of supporting surface like this in face of processing, flatness can reach the effect of progressively successively decreasing; The variation of flatness can reach in the first step 0.10, in second step 0.05, in the 3rd step 0.025, and as long as flatness 0.025 with the linearity of the length direction of interior workpiece also necessarily less than 0.02, the linearity of short direction is less than 0.01; Can guarantee the qualification rate of product like this.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
