The utility model is characterized in that the end surface milling fixture comprises a base, two positioning bodies vertically fixed on the base, two brackets vertically pressed on the base, and two clamping bodies perpendicular to the brackets, wherein the positioning bodies are respectively arranged on the left side and the right side of the base along the horizontal direction; each clamping body is provided with an adjusting screw; the two clamping bodies are parallel to the upper surface of the base and are in slide fit with the brackets respectively; a fixed body is arranged on each positioning body in the vertical direction; a special-shaped cam is fixed with the base through threads; two revolving shafts are respectively arranged on the left side and the right side of the special-shaped cam; the revolving shafts are vertically fixed on the base; two crutch-shaped transmission rods are in slide fit with the two revolving shafts respectively and are parallel to the upper surface of the base; and three limit pins are uniformly distributed on the upper horizontal surface of each positioning body. The utility model has the advantages of convenient use, agility, accuracy, low probability of workpiece deformation, guaranteed precision, improved productivity, and reduced cost.
Description
Technical field
The utility model belongs to processing component frock clamp field; Ultrathin workpieces milling fixture field particularly.
Background technology
Pit is the aperture critical piece of camera, monitor, and the precision of pit directly influences the definition of camera lens.On the pit by three equally distributed limiting stands 2 of particular design ' (referring to accompanying drawing 2, accompanying drawing 3, wherein pit unthreaded hole 1 ', pit limiting stand 2 '.) form, come successively to determine that aperture blades is opened and closed exact position.Also be uniform-distribution with on the pit three unthreaded holes 1 ', on its unthreaded hole aperture blades is installed.If the flatness of the precision of the aperture of unthreaded hole, position degree and limiting stand, position degree, milling face does not reach designing requirement, will cause aperture can not open smoothly, thereby influence the definition of camera lens with closed.Originally pit limiting stand milling fixture is to adopt with three unthreaded hole location, utilizes screw-clamped by pressing plate.Shortcoming is that clamping speed is slow, and workpiece is yielding, and milling facial plane degree can't guarantee.Not only production efficiency is low, and the fraction defective height of product, and production cost is very big.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of easy to use, and is quick, accurately ultrathin workpieces face milling anchor clamps.
The purpose of this utility model is achieved in that ultrathin workpieces face milling anchor clamps, it is characterized in that, comprises base, is vertically fixed on the positioning body on the base, respectively has one about the positioning body horizontal direction; Vertically be press-fit on the base two supports and perpendicular to the clamping body of support, two clamping bodies respectively have one to adjust screw, two clamping bodies are parallel to the upper surface of base, and are slidingly matched with support respectively; The positioning body vertical direction has a fixed body, by screw thread special-shaped cam and base are fixed, abnormity cam the right and left respectively has a gyroaxis, gyroaxis is vertically fixed on the base, two are turned the shape drive link and are slidingly matched with two gyroaxises respectively, and are parallel to the upper surface of base, on the described positioning body horizontal upper end face, be uniform-distribution with three spacer pins, correspond respectively to three unthreaded holes of workpiece.By the rotation of special-shaped cam, making two, to turn the shape drive link be respectively the center side-to-side movement with the gyroaxis, drives two clamping bodies and carry out clamping.
On the described special-shaped cam by the fixing handle of screw thread.
Described clamping body and support are slidingly matched by the dove-tail form slideway.
Compared with prior art, the beneficial effects of the utility model are: because the utility model is three unthreaded holes with workpiece is the location, is clamping with workpiece external diameter holotype, therefore uses this anchor clamps, convenient, quick, accurately, workpiece is not yielding, precision is guaranteed, has improved productivity ratio, has reduced cost.
Description of drawings
Fig. 1 is the utility model structural representation: wherein, 1 base, 2 fixed bodies, 3 handles, 4 special-shaped cams, 5 gyroaxises, 6 turn the shape drive link, 7 supports, 8 positioning bodies, 9 spacer pins, 10 workpiece, 11 clamping bodies, 12 adjust screw.
Fig. 2 is a work piece pit sectional front view: wherein, and 1 ' pit unthreaded hole, 2 ' pit limiting stand.
Fig. 3 is a work piece pit cross sectional side view: wherein, and 1 ' pit unthreaded hole, 2 ' pit limiting stand.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to accompanying drawing 1: ultrathin workpieces face milling anchor clamps, comprise base 1, fixed body 2, handle 3, special-shaped cam 4, gyroaxis 5 turns shape drive link 6, support 7, positioning body 8, spacer pin 9, clamping body 11 is adjusted screw 12.Wherein, positioning body 8 is vertically fixed on the base 1, and a positioning body 8 is respectively arranged about horizontal direction; Two supports 7 and two clamping bodies, 11 vertical being press-fit on the base 1 perpendicular to support, two clamping bodies respectively have one to adjust screw, adjust screw 12 for two and connect respectively by screw thread and two clamping bodies 11, two clamping bodies 11 are slidingly matched by dove-tail form slideway (the dove-tail form slideway is positioned at the survey of two clamping bodies 11) and support respectively; The positioning body vertical direction has a fixed body 2, and by screw thread that special-shaped cam 4 is fixing with base 1, the shape cam is that gyration is done at the center with fixed body 2.On special-shaped cam by the fixing handle 3 of screw thread.Abnormity cam the right and left respectively has a gyroaxis 5, gyroaxis is vertically fixed on the base 1, two are turned shape drive link 6 and are slidingly matched with two gyroaxises respectively, and the upper surface that is parallel to base, on the horizontal upper end face of described positioning body 8, be uniform-distribution with three spacer pins 9, correspond respectively to three unthreaded holes of workpiece.By the rotation of special-shaped cam, making two, to turn the shape drive link be respectively the center side-to-side movement with the gyroaxis, drives two clamping bodies and carry out clamping.
During use, three unthreaded holes of workpiece 10 (pit) are placed on respectively on three spacer pins 9 of positioning body 8, hand is pulled handle 3, special-shaped cam 4 is rotated, turn shape drive link 6 by two, promote two clamping bodies 11 and do rectilinear motion to the direction of workpiece pit 10 simultaneously, workpiece pit 10 is clamped.Carry out three limiting stand face milling processing of workpiece, opposite when action was with clamping when workpiece unloaded.
