Embodiment
Below against accompanying drawing, by the description to optimum embodiment, embodiment of the present utility model is made into one Step detailed description.
As shown in figure 1, the positioning fixture, including mounting seat 5, the top of mounting seat 5 is provided with and the positioning hole adaptation of workpiece Detent mechanism 1, the bottom of mounting seat 5 is provided with cylinder 6;It is located at the lower section of detent mechanism 1 in mounting seat 5 to be provided with mounting hole, mounting hole Provided with the hook 2 that mounting hole realizes Workpiece clamping can be moved and stretched out in mounting hole;Hook 2 and mounting seat 5 pass through Guiding machine Structure is connected;The piston rod connection that hook 2 and cylinder 6 are stretched into mounting hole.
Detent mechanism 1 is used for the sheet metal component for positioning and supporting workpiece;Hook 2 is used for hook and clamps sheet metal component;The conduct of cylinder 6 Power part, hook 2 is slided under the driving of cylinder 6, and guiding mechanism provides mobile guide effect, to reach clamping workpiece or beat The state opened;Mounting seat 5 had both installed the installation that cylinder 6 is also convenient for this fixture, to meet the location requirement of workpiece diverse location.Hook Pawl 2 can move and rotate under the driving of cylinder 6 to clamp workpiece, and this positioning fixture can be applied to narrow space region, half Use demand of the closed area such as total spell station to bottom clamping etc..
As shown in Figures 2 and 3, hook 2 includes connecting plate 6, and guiding mechanism includes the guide groove 10 on connecting plate 6, Also include the guide finger 3 that in mounting seat 5 and guide groove 10 is adapted to;The piston rod of the one end of connecting plate 6 and cylinder 6, which is fixed, to be connected Connect, the other end of connecting plate 6 is provided with and can move and rotate to realize the crotch 8 of work piece holder under the driving of cylinder 6.Will positioning In the positioning hole of the insertion sheet metal component of mechanism 1, cylinder 6 is worked, and piston rod stretches out, and hook 2 is rotated after moving up, and crotch 8 is caught on Sheet metal component, realizes the clamping of sheet metal component.
Guide groove 10 is made up of clamping guide part 11 and rotary steering portion 12;Clamp the center line and cylinder 6 of guide part 11 Piston rod hinge central point of hole on one wire;The center line in rotary steering portion 12 and the centreline space for clamping guide part 11 Set in angle.
10 points of guide groove is clamping guide part 11 and the two parts of rotary steering portion 12 on hook 2.Clamp in guide part 11 The hinge central point of hole of heart line and cylinder 6 is on one wire.The piston rod of cylinder 6 stretches out, and when being moved along clamping guide part 11, pushes away Dynamic hook 2 is translated along the centerline direction for clamping guide part 11, and the effect in rotary steering portion 12 is the place end of crotch 8 of hook 2 Rotated under the drive that cylinder 6 moves along a straight line along rotary steering portion 12, hook 2 is realized sheet metal component and clamp and release function. The another of rotary steering portion 12 is act as, after the completion of work piece operations, and the piston rod of cylinder 6 is retracted, the place end of crotch 8 of hook 2 Reversely rotated under the drive that cylinder 6 moves along a straight line along rotary steering portion 12, rotate crotch 8, get out of the way mechanical interferences.
The angle of centreline space of the center line in rotary steering portion 12 with clamping guide part 11 is 20 °.Rotary steering portion 12 Center line with clamp guide part 11 centerlines control at 20 °, will make mechanism that there are preferable movement effects.Influence hook The parameter of the anglec of rotation of pawl 2 is swivelling chute effective end center and the pan line of hook 2 and clamps the angle between center line α, clamps contract by distance W and the anglec of rotation of hook 2 and the length H of hook 2 is relevant, in the direction of motion of cylinder 6, hook 2 , the selection actual anglec of rotation β=α of hook 2 also related to the above apart from S of clamping face movement.
Detent mechanism 1 is by the location-plate 13 of the side connection with the top of mounting seat 5 and the positioning provided with the top of location-plate 13 Pin 14 is constituted.Location-plate 13 is connected on the side on the top of mounting seat 5, plays a part of stepping down and preventing interference.Alignment pin 14 Sheet metal component is played a part of positioning and supported.The material of alignment pin 14 is 42CrMo, and plating nickel on surface is handled, and heat treatment hardness is 45-55HRC。
Preferred orientation plate 13 is L shaped plate, convenient for assembly.Preferred orientation plate 13 and alignment pin 14 are integral type structure, to carry For reliable positioning supporting role.
Mounting hole is located at the center of mounting seat 5, and alignment pin 14 is located at the top of hook 2.Alignment pin 14 and hook are set Put rational in infrastructure, do not produce interference mutually, under the two collective effect, realize the reliable location of workpiece.
Hook is provided with resigning notch on the one end for setting crotch 8;Resigning notch provides resigning when hook 2 is moved and rotated Effect, prevents interference between workpiece.
Nickel Plating Treatment after hook surface is heat-treated.Hook 2 is 42CrMo using material, and plating nickel on surface is handled, at heat Reason hardness is 45-55HRC, and the thickness 8mm of hook 2, each seamed edge needs chamfering, and mechanism design is uniform, and intensity is enough.On hook 2 The width of guide groove 10 is typically designed as 6.1mm.
The utility model positioning fixture, by the structure setting of alignment pin 14 and hook 2, to that can not be determined with locating piece The semiclosed region of position clamping or body frame or area of space are narrow and small, are to play a part of positioning to rise again to sheet metal component To the effect of clamping.
Obvious the utility model, which is implemented, to be not subject to the restrictions described above, as long as employing method of the present utility model The improvement for the various unsubstantialities that design and technical scheme are carried out, within protection domain of the present utility model.
