Beneficial effect:
The utility model broaching fixture structural design is simple, rationally, compressed oil cylinder is horizontally placed on the work top of broaching machine body, and thrust is consistent with the power of wire pulling method, and acting in conjunction on workpiece, thus makes Work-sheet pressing more reliable; Meanwhile, the end face of workpiece also can be processed with both sides end face simultaneously, add machinable position, decrease the possibility of repeated clamping; Adopt the clamping of straight pushing locking oil cylinder simultaneously in the horizontal direction, reduce and take effective travel, thus the object of the more parts of clamped one time can be realized; The utility model broaching fixture clamped one time can process more face, decreases clamping workpiece number of times, decreases position error, improve product quality; The multiple workpiece of clamped one time, substantially increases production efficiency.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model broaching fixture;
Fig. 2 is the left view of the utility model broaching fixture.
Detailed description of the invention
As shown in Figure 1, the utility model broaching fixture, is installed in the work top of broaching machine body 1, comprises compressed oil cylinder 2, guide holder 3, compact heap 4 and locating piece 5.
This compressed oil cylinder 2 is fixedly arranged on the work top of this broaching machine body 1, and it comprises cylinder body 21 and cylinder putter 22; This cylinder body 21 level is fixed on the work top of this broaching machine body 1; It is inner that this cylinder putter 22 one end level penetrates cylinder body 21, and it is outside that other end level passes cylinder body 21.
This guide holder 3 is arranged at the stem of the cylinder body 21 of this compressed oil cylinder 1, and its upper end level is through offers pilot hole 31.
This compact heap 4 is movably arranged in the pilot hole 31 of this guide holder 3, the inwall sliding connection of itself and pilot hole 31; Wherein, penetrate compact heap 4 inside middle portion in the pilot hole 31 that this guide holder 3 is stretched in one end that the cylinder putter 22 of this compressed oil cylinder 2 passes cylinder body 21 outside, this cylinder putter 22 penetrates one end of compact heap 4 inside middle portion and compact heap 4 is fixed by straight pin 6, can drive compact heap 4 together along pilot hole 31 horizontal slip when compressed oil cylinder 2 drives cylinder putter 22 to stretch.
The work top that this locating piece 5 is also fixedly arranged on this broaching machine body 1 is positioned at guide holder 3 side, and it comprises axial location block 51 and bottom locating piece 52, wherein, this axial location block 51 is positioned at guide holder 3 side, keeps a determining deviation between itself and guide holder 3, the end face of this axial location block 51 near guide holder 3 side and workpiece 8 close contact, this axial location block 51 and the end face of workpiece 8 close contact also offer groove 211, bottom this, locating piece 52 is fixedly arranged on the work top of the broaching machine body 1 between axial location block 51 and guide holder 3, bottom this, the top of locating piece 52 is by alignment pin 7 fixation workpiece 8, after workpiece 8 is fixed on bottom locating piece 22 end face, now the cylinder putter 22 of compressed oil cylinder 2 stretches out and promotes compact heap 4 by workpiece 8 from laterally holding out against, the upper end of the workpiece 8 after clamping, front-end and back-end are all stretched out outside locating piece 5, therefore, the upper surface of workpiece 8, front end face and rear end face can realize wire pulling method simultaneously, because the direction of broaching is consistent with the direction of clamping force, the workpiece 8 made clamps more firm, reliably.
