Detailed description of the invention
Referring to the accompanying drawing that the utility model embodiment is shown, the utility model below will be described in more detail. But, this realityWith novel can be with many multi-form realizations, and should not be construed as the restriction of the embodiment being subject in this proposition. On the contrary, proposeThese embodiment are abundant and complete open in order to reach, and it is new to make those skilled in the art understand this practicality completelyThe scope of type. In these accompanying drawings, for clarity sake, may amplify size and the relative size in layer and region.
With reference to Fig. 1-2, the utility model provides a kind of impartial pressue device for stamping riveting machine, includes twoDrift 5, and two drifts 5 are installed in punch carrier 1 by an impartial pressure rod 11, in the time being added with redundant force on a drift 5Wait, pass to another drift by impartial pressure rod, make two drifts stressed the same, thereby make impartial pressurization.
In the present embodiment, be provided with an accommodating cavity 1001 in punch carrier 1, accommodating cavity 1001 specifically can be a rectangleCavity; Impartial pressure rod 11 is installed to by a connection piece 10 on the sidewall of accommodating cavity 1001, and impartial pressure rod 11 levels are establishedPut, and impartial pressure rod 11 can be around the slight rotation in connector 10 left and right in perpendicular; Preferably, impartial pressure rod 11 closesIn connector symmetry. Wherein, connector 10 can adopt the structures such as screw to realize, and is not restricted herein.
In the present embodiment, impartial pressure rod is respectively arranged with screwed hole on 11 two ends, and two screwed holes vertically arrange and closeBe symmetrical arranged in connector 10; In two screwed holes, be provided with a pressurization adjusting bolt 2, stretch out the lower end of pressurization adjusting bolt 2The lower surface of impartial pressure rod 11, the upper surface that impartial pressure rod 11 is stretched out in the upper end of pressurization adjusting bolt 2, and pressurization regulates spiral shellOn the upper end of bolt 2, be also arranged with stop nut 3, stop nut 3 is for preventing the loosening of adjusting bolt 2 that pressurize.
In the present embodiment, on the bottom of accommodating cavity 1001, be provided with two through hole, and through hole extends through drift downwardsFrame 1; Two through hole regulates spiral shell 0 bolt 2 coaxial and relative with the pressurization of two on impartial pressure rod 11 respectively. Wherein, through hole is a ladderHole, is made up of hole 1002, large footpath and diameter holes 1003, and hole, large footpath 1002 is positioned at the upside of diameter holes 1003.
In the present embodiment, be provided with drift 5 in two through hole, drift 5 can move axially with respect to through hole; Drift 5Upper end is placed in through hole, the lower surface of punch carrier 1 is stretched out in lower end, and the lower surface of pressurization adjusting bolt 2 is just pressed in tap 5On upper surface; Concrete, on drift 5, be provided with upper limit dish 501 and lower limit dish 502, upper limit dish 501, lower limit dish 502Coaxially arrange with drift 5; Upper limit dish 501 is positioned at hole, large footpath 1002, and the diameter of upper limit dish 501 is greater than diameter holes 1003Diameter; Lower limit dish 502 is positioned at punch carrier 1 bottom outside, and the diameter of lower limit dish 502 is greater than the diameter of small-bore.
Between drift 5 and through hole, be also provided with compression spring 4, when drift 5 axially moves down, compression pressure spring4; Concrete, compression spring 4 is enclosed within on drift, and compression spring 4 is positioned at hole, large footpath 1002, and the upper end of compression spring 4 is againstOn the lower surface of upper limit dish 501, the lower end of compression spring 4 is against the transition face between hole 1002, large footpath and diameter holes 1003On.
Be described further with regard to specific works principle and effect below:
Described in Fig. 1-2, the first workpiece 6 is fixed on a fixture 9, and second workpiece 8 is positioned on the first workpiece 6, and logicalCross two rivets 7 and fix the first workpiece 6 and second workpiece 8; The impartial pressue device that the utility model provides is arranged on punching press rivetingPick upper, stamping riveting machine drives punch carrier 1 to press to workpiece, makes the lower end of two drifts 5 carry out punching press to two rivets 7. When itIn when being added with redundant force on a drift 5, be delivered on another drift 5 impartial pressure rod 11 left sides by impartial pressure rod 11Right fine rotation, and under the effect of compression spring 4, finally make two rivets obtain impartial rivet force.
In addition, the utility model also can, by the rotation adjusting bolt 2 of pressurizeing, be adjusted the stamping press of drift 5, withReach satisfactory rivet force, compression spring 4 plays the effect of the impartial pressure rod 11 of balance simultaneously, and impartial pressure rod 11 is to connectFitting 10 carries out axial fine rotation for fulcrum, until the pressure that two drifts 5 bear is the same.
For example, when the pressurization adjusting bolt in left side is down rotated, pressing respective side drift to move down and realizing increasesThe object of stamping press; In the process that left side drift presses down, compress the compression spring in left side, now compression spring rushing left sideHead has reaction force, and this reaction force upwards pushes up the drift in left side, and left side drift upwards pushes up again the pressurization adjusting bolt in left side,Make impartial pressure rod taking connector as the clockwise fine rotation of fulcrum. Impartial pressure rod clockwise rotates and makes, the adding of right sidePress adjusting bolt further toward the drift that presses down right side; The drift on right side presses down and can make the compression spring compression on right side,Right atrial pressure spring can produce reaction force to drift again, makes the counterclockwise fine rotation of impartial pressure rod, thereby drives left sideDrift press down. Said process back and forth, until the compression spring of left and right sides is added in the reaction force phase on impartial pressure rodDeng time, it is motionless that impartial pressure rod is just stablized, thereby ensured that the drift of left and right sides is stressed the same.
Stop nut mainly plays the loosening of the adjusting bolt 2 that prevents from pressurizeing, when regulating after pressurization adjusting bolt, and can be byStop nut screws.
Because should be understood that the utility model, those skilled in the art can realize not with many other concrete formsDepart from the spirit or scope of itself. Although described case study on implementation of the present utility model, should understand the utility model and should notBe restricted to these embodiment, the spirit of the present utility model that those skilled in the art can define as appended claimsChange and amendment with making within scope.
