Abstract
The invention discloses an external hanging block self-clamping fixture, which belongs to a tool in the motor manufacturing industry and particularly relates to an ideal self-clamping fixture for the self-clamping of a circumferential equaling punching die and an electric spark machining die. Circumferential equaling identical male die troughs are arranged on a body trough plate. Male dies are arranged in the male die troughs with shapes consistent with those of the male dies. The upper and lower ends of each male die trough on the body trough plate are provided with an expansion hair crack respectively. The male die trough, the corresponding expansion hair crack and a corresponding lower expansion hair crack are positioned on the same circumferential equaling diameter on the body trough plate. External hanging holes are reserved between every two adjacent expansion hair cracks on the body trough plate, and are used for arranging external-circle hanging block clamping devices. The self-clamping fixture has the advantages that: the fixture is rationally designed, simply structure and in no need of an outer sleeve, a splicing block or a filling block, and completely saves a pressing positioning system of the conventional fixture; and the male dies and the body trough plate are fastened completely by clamping forces between materials of each of the male die trough, the expansion hair crack and the lower expansion hair crack and the material of the body trough plate, so the fixture is ideal.
Description
Technical field:
The outer hanging block self-clamping fixture of the present invention belongs to motor manufacturing machine equipment, particularly branch blanking mould and the outer hanging block self-clamping fixture of spark machined mould such as circumference.
Background technology:
At present, the anchor clamps major part of compound press tool and electric machining mould is made up of parts such as overcoat, body, convex modules, and body adopts spacer-type or assembled piece type usually.The basic principle of spacer-type and assembled piece type anchor clamps is identical, the two all is directly to hold out against convex module by overcoat with bolt to be assembled on the body, holding out against in the process of bolt, if the center line of bolt center line and convex module has skew, pressure will cause a moment of torsion, cause the distortion of convex module weakest part, and make cushion block or piece produce microdisplacement, the five equilibrium error that finally causes body frid flute profile, the morpheme error, the scale error of bottom land, simultaneously, in the assembling process of convex module and body, the perpendicularity of convex module and body is difficult to adjust, anchor clamps do not reach expected effect, have influenced the workmanship of motor to a great extent.
Summary of the invention:
The outer hanging block self-clamping fixture goal of the invention of the present invention is: provide a kind of from clamping the blanking mould of circumference five equilibrium and the anchor clamps of electric machining mould.
The outer hanging block self-clamping fixture of the present invention is achieved in that by convex module, the body frid, and convex module groove, outer hanging hole, harmomegathus slit and following harmomegathus slit and outer hanging block are formed; Be shaped on the identical convex module groove of circumference five equilibrium on the body frid, convex module is installed in the convex module groove consistent with the convex module shape; Each convex module groove upper end on the body frid is shaped on the harmomegathus slit, and the lower end is shaped on down the harmomegathus slit; Convex module groove, harmomegathus slit and following harmomegathus slit are positioned on the body frid on the same five equilibrium diameter; Terminal leaves the tensioner micropore under the following harmomegathus slit, and circular hole or polygonal hole or imitative mallet type can be processed in this hole; Hanging hole outside the position is shaped between the adjacent harmomegathus slit of on the body frid each, the extension pawl of outer hanging block and the supporting installation of outer hanging hole; Be shaped on second circle on the outer hanging block towards the part slotted eye.
The grooved of the convex module groove on the body frid is selected rational tolerance for use with cooperating of convex module, and terminal leaves the tensioner micropore under harmomegathus slit and the following harmomegathus slit, and the effect of tensioner micropore is to eliminate stress and can plays the effect that elasticity disappears mutually or grow mutually; Convex module is by the effect of convex module groove, harmomegathus slit and the following harmomegathus slit and the outer hanging block of body frid, convex module is packed in the convex module groove of body frid, because opening, outer hanging block interaction result between groove, convex module and body frid are the interaction that tight fit is in adjustable state, body frid material, tightly are fixed in the groove of frid.
The beneficial effect of the outer hanging block self-clamping fixture of the present invention: this jig Design is reasonable, simple in structure, do not need overcoat, piece or cushion block, the navigation system that holds out against that has saved old-fashioned anchor clamps fully, the fastening clamping force that forms mutually between the material of convex module groove, harmomegathus slit and following harmomegathus slit, outer hanging block and body frid on the body frid that relies on fully of convex module and body frid realizes, is a kind of desirable self-clamping fixture.
Description of drawings:
Accompanying drawing 2 is that the outer hanging block self-clamping fixture convex module master of the present invention looks schematic diagram
Accompanying drawing 3 is the local enlarged diagrams of the outer hanging block self-clamping fixture of the present invention
Among the figure: body frid 1, convex module groove 2, outer hanging hole 3, harmomegathus slit 4, following harmomegathus slit 5, convex module 6, outer hanging block 7
Embodiment:
The outer hanging block self-clamping fixture of the present invention is made up of convex module 6, body frid 1, convex module groove 2, outer hanging hole 3, harmomegathus slit 4, following harmomegathus slit 5 and outer hanging block 7; Be shaped on the identical convex module groove 2 of circumference five equilibrium on the body frid 1, convex module 6 is installed in the convex module groove 2 consistent with convex module 6 shapes; Each convex module groove 2 upper end on the body frid 1 are shaped on harmomegathus slit 4, and the lower end is shaped on down harmomegathus slit 5; Convex module groove 2, harmomegathus slit 4 and following harmomegathus slit 5 are positioned on the body frid 1 on the same five equilibrium diameter; 5 times terminals of following harmomegathus slit leave the tensioner micropore, and circular hole or polygonal hole or imitative mallet type can be processed in this hole; Hanging hole 3 outside the position is shaped between the adjacent harmomegathus slit 4 of on body frid 1 each, the extension pawl of outer hanging block 7 and outer hanging hole 3 supporting installations; Be shaped on slot wedge dovetail slotted eye on the outer hanging block 7.
