Abstract

The utility model relates to a clamp used for milling the arcs of a left clamp and a back clamp. The utility model comprises a machine base which is provided with an X reference column which is arranged vertically, a Y reference column arranged transversally and a Z reference column perpendicular to the machine base. The machine base is also homologically provided with an X clamping element, a Y clamping element and a Z clamping element. The utility model has the advantages of simple and reasonable structure, and simple, convenient and practical operation. The utility model changes from one working procedure having billet positioning into two working procedures having billet positioning and has a positioning mode of a half machine work surface and a half billet surface. The utility model accords with the tool measuring requirements. The one-off lower bound qualification rate rises from less than 20% to more than 90% after the utility model is improved. The utility model has good use effects.

Description

A left side, Back Caliper Mill Arcuate Clamp

Technical field

The utility model relates to a kind of frock clamp, an especially a kind of left side, Back Caliper Mill Arcuate Clamp that is used for the J200 caliper.

Background technology

The left side of present J200 caliper, Back Caliper Mill Arcuate Clamp complex structure, unreasonable, use inconvenience, and behind the present anchor clamps first operation blank location, all the other operations all are the consistent technology of machined face location, cause datum drift excessive, waste product increases, cost improves, and result of use is bad.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of simple in structure, a left side, Back Caliper Mill Arcuate Clamp that result of use is good are provided.

The utility model solves the technical scheme that its technical problem adopts: a this left side, Back Caliper Mill Arcuate Clamp, comprise support, support is provided with the X of vertical setting to reference column, the Y of horizontally set is to reference column, and perpendicular to the Z of support to reference column; Also be provided with on the support corresponding X to clamping element, Y to clamping element and Z to clamping element.

The effect that the utility model is useful is: the utility model is simple and reasonable, and is simple, convenient, practical.And technology is made into two procedures from a procedure blank location blank location is all arranged, the mode of half black skin location of half machined face, meet the cubing Testing requirement, through making lower limit qualification rate from rising to more than 90% less than 20% after improving, result of use is good.

Description of drawings

Fig. 1 is that master of the present utility model looks cross-sectional view;

Fig. 2 is a plan structure schematic diagram of the present utility model.

Description of reference numerals: Z is to clamping element 1, back-moving spring 2, double-screw bolt 3, pressure head 4, support 5, Z is to reference column 6, and Y is to reference column 7, and X is to clamping element 8, and Y is to clamping element 9, and Y is to reference column bearing 10, X is to clamping element bearing 11, and Y is to clamping element bearing 12, and X is to reference column 13, and X is to reference column bearing 14.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

A this left side, Back Caliper Mill Arcuate Clamp comprise support 5, and support 5 is provided with the X of vertical setting to reference column 13, and the Y of horizontally set is to reference column 7, and perpendicular to the Z of support 5 to reference column 6; X is located at X on reference column bearing 14 to reference column 13, is being provided with X to clamping element 8 with X to reference column 13 relative sides on the support 5, and X has helicitic texture to clamping element 8, is located at X on clamping element bearing 11, can be in X threaded adjusting on clamping element bearing 11.Y has two to be located at Y to reference column bearing 10 to reference column 7, be provided with two Y to clamping element 9 with Y to reference column 7 relative sides on the support 5, Y also has helicitic texture to clamping element 9, is located at Y on clamping element bearing 12, can be in Y threaded adjusting on clamping element bearing 12.Z has three to reference column 6, and two in the left side, and one on the right side.Be provided with Z to clamping element 1 above reference column 6 at Z, Z is a pressing plate to clamping element 1, and this pressing plate is enclosed within on the double-screw bolt 3 and with this double-screw bolt 3 and is threaded, and pressing plate is provided with the pressure head 4 that is complementary with workpiece, and this pressing plate is provided with back-moving spring 2.

During use, earlier correctly place three Z on reference column 6 workpiece, the earhole machined surface is against Y to reference column 7, caliper one side is positioned X to reference column 13, and the X with correspondence tightens the workpiece that is fixed to clamping element 9 to clamping element 8, Y again, Z to the left side carries out precompressed to clamping element 1 earlier, and then the Z that compresses right side pincers pin feels to have the resistance of 10N get final product to clamping element 1, the Z in left side tightened to clamping element 1 at last again.

The innovative point of this workpiece is: all sizes of product all are the sizes that black skin arrives machined face, be different from all the other products: behind the first operation blank location, all the other operations all are the consistent technology of machined face location, cause datum drift excessive, waste product increases, and cost improves.Through anatomizing, technology is made into two procedures from a procedure blank location blank location is all arranged, the mode of half black skin location of half machined face meets the cubing Testing requirement, makes a lower limit qualification rate from rising to more than 90% less than 20% after improving.

The operation notice of these anchor clamps: 1. must keep anchor clamps locating surface 16 and earhole face to keep clean when clamping, as the surface dust be arranged, iron filings can influence machining accuracy.2. this workpiece is a thin-wall part, and pincers pin platen pressure is excessive, can make the distortion of pincers pin in the processing, influences the depth of parallelism, perpendicularity, so must carry out according to the requirement of anchor clamps operation principle.
