The specific embodiment
As illustrated in fig. 1 and 2, a kind of broaching tool self-clinching fastener, comprise a slide carriage 2 that can move along broaching machine guide pillar 1, it is positioned on the guide pillar 1 by fairlead 11, one locating hole 21 is set above the slide carriage 2, chuck body 3 is installed on it, body outside socket one overcoat 4, overcoat 4 tops are installed in meeting and discussing of broaching machine workbench 5 bottoms and 6 offset griffing Shi Keyu.
Chuck body 3 inside are provided with a centre bore 31, the body centre bore can be circle or rectangle, adopt circular in the present embodiment, the body head is provided with a plurality of the connection with centre bore 31 and the equally distributed clamping hole 32 of rich centre bore circumference, adopt three in the present embodiment, as shown in Figure 3, each clamping hole 32 the inside all is provided with a slide block 33 and steel ball 34; Described body 3 outer middle side parts are provided with two boss 35,36, and wherein convex platform 35 diameters are greater than body 3 head diameters and less than lower convex platform 36 diameters, and the bottom face 361 of lower convex platform 36 is inconsistent with slide carriage 2 upper surfaces; And the locating hole 21 on the slide carriage 2 is passed in body 3 bottoms, and with nut 22 positioning and fixing.At this, when centre bore 31 ' adopt is square, as shown in Figure 6, body 3 ' head only be provided with two clamping holes 32 ', both are relative, and centre bore is symmetrical arranged.
Match with the lower convex platform 36 at body middle part in described overcoat 4 endoporus apertures, endoporus top is provided with an annular lip 41, flange 41 internal diameters match with body 3 heads, its be provided with one can with body clamping hole 32 corresponding back taper type grooves 411, one compression spring 7 is set between the upper surface 362 of flange bottom face 412 and body lower convex platform 36, make between chuck body 3 and the overcoat 4 form movingly a kind of, it utilizes the variation of relative position between the two, realize the interior pressure of slide block 33 in the clamping hole 32 or move outward, thereby realize the clamping of broaching tool 8 and unclamp.
Here, consideration for the ease of the installation aspect, one steel ball installing hole is set on the coat, when assembling, at first in each clamping hole 32, only put into slide block 33, overlap upper spring 7 and overcoat 4 subsequently, then steel ball 34 is put into and rotary sleeve 4 from the steel ball installing hole of overcoat, steel ball 34 is entered in one of them clamping hole, by that analogy, up to after all clamping holes 32 are all put into steel ball 34, again installing hole being sealed with wax.
Shown in Figure 4 and 5, when wanting tool changing, slide carriage 2 drives chuck body 3 and rises and close gradually workbench 5 along guide pillar 1, up to overcoat 4 tops be arranged on meeting and discussing of workbench 5 bottoms and 6 offset, then, along with the continuation of slide carriage 2 is risen, under 6 the effect of meeting and discussing 4 times pressing springs of overcoat 7 and relatively chuck bodies 3 move down, meanwhile, steel ball 34 in the body clamping hole 32 slides along the inclined-plane of overcoat back taper groove 411 and enters the bosom of groove 411, and slide block 33 also takes place by outer moving synchronously, thereby it is separated with the groove 81 that engages of broaching tool handle, at this moment, just can unload broaching tool 8 very easily.Change new cutter subsequently, slide carriage 2 beginnings move down along guide pillar 1, and overcoat 4 moves on beginning at relative body 3 under the effect of compression spring 7 restoring forces, force the steel ball 34 in the body clamping hole 32 to slide along the inclined-plane of overcoat back taper groove 411, it is moved toward top, inclined-plane by bosom of groove 411, and then drive slide block 33 and move extruding in also taking place synchronously, slide block 33 heads are fastened with the groove 81 that engages on the broaching tool handle, thereby make its tightly embrace the broaching tool handle, realize the self-tightening clamping.
The utility model unloads in cutter and the dress cutter process whole, and the user only need draw sword and slotting tool, and is simple to operate and make things convenient for, and reduced labour intensity.In addition, chuck body 3 is provided with a plurality of clamping slide blocks 33, and the relative centre bore 31 of slide block is circularly and evenly distributed, thereby in clamping, can cancelling out each other with joint efforts of the active force of 33 pairs of broaching tool handles of each grip block, can not occur one and make the outer inclined to one side active force of broaching tool handle, thereby guarantee that the broaching tool spindle clamp holds the stability of location, ensure the machining accuracy of broaching tool 8.
