Description
Affiliated technical field
The utility model belongs to mechanical processing industry, particularly uses machined into eccentric element technical field.
Background technology
In the work of the big part of machining eccentric throw, lathe has several processing methods, but bringing some difficulties to the operator aspect its processing and the centering, as: when scroll chuck processing is eccentric, owing to can't correctly calculate the centering error distance, make the eccentric size of processing work can't reach requirement.Add man-hour at chuck, can also process when eccentric throw is little, when eccentric throw exceeded " 5mm ", the operator just can't process by centering.When using dual chuck, centering difficulty not only, but also brought unsafe factor for operator's the person and equipment.At these problems, the utility model has designed an accentric multipurpose clamp.
Summary of the invention
In order to solve the existing big part instrument of eccentric throw that is used to process, the problem that aspect processing and centering, exists, the utility model provides a kind of accentric multipurpose clamp, these anchor clamps can not only guarantee the processing of the big part of eccentric throw, and can make things convenient for daily operation, the location can be as accurate as 0.01mm, and is safe and reliable.
The utility model is mainly realized by following structure.Mainly form by main keeper, assist location clamping element, running fix part, keeper, screw rod, nut and two corner blocks.Main keeper and assist location clamping element are fastened together by screw rod, and running fix part and keeper are put into two holes of main keeper respectively, fix with nut.Two corner blocks are fastened in " V " shape groove of main keeper and assist location clamping element by screw respectively.Described accentric multipurpose clamp carries out the processing of two " V " shape groove on lathe, and through proofreading and correct repeatedly, the error that makes it two sides is between 0～0.02mm; Axis based error is limited in the 0.02mm when 200mm.
The technical scheme that the utility model accentric multipurpose clamp is adopted is: the three-jaw of lathe is unloaded, after main keeper and assist location clamping element adjusted to the size that is fit to processing work by screw rod, running fix part and keeper are put into two holes of main keeper, with nut it is adjusted to correct position, but should not be too tight, they are put into the draw-in groove of scroll chuck together, rotating chuck spanner again, its anchor clamps ecto-entad is moved, workpiece is placed on the main keeper, makes the line of its line of eccentricity align the center line of V-type groove, tighten two screw rods, main keeper and assist location clamping element are clamped workpiece, carry out centering then.At first overlap with the lathe spindle line centre of gyration with dial gauge centering workpiece centre, it is vertical again the workpiece line of eccentricity to be placed horizontally at dial gauge, mobile from inside to outside anchor clamps, eccentric throw is conformed to actual size, and then the nut on the keeper that screws up with a wrench, just can carry out the bigger part processing of eccentric throw afterwards.
After the utility model accentric multipurpose clamp comes into operation, easy to use, simple to operate, be applicable to more than the processing φ 16mm, the various eccentric throws that φ 80mm is following, but length can not surpass 300mm, be applicable to two kinds of lathes of C620 and CA6140, the location can be as accurate as 0.01mm, and is safe and reliable.
