Abstract
The utility model relates to an interlinked clamp head for a precision square hole. The end face of a main shaft 5 is provided with four guide positioning inclined surface. Four guide positioning inclined surface on both ends of push block gripping jaws 6-9 sliding on the groove which is hung on a connecting body 3 are blocked respectively by the positioning inclined surface raised in the double sigmoid square hole guide groove of a positioning guide body 1 and the four guide positioning inclined surface. A gear wheel outer sleeve 2 is driven by a gear wheel spanner 10 to do a circular motion in situ. The outer screw thread of the connecting body 3 is driven by the screw thread in the gear wheel spanner 10 to be displaced in an axial direction, and the push block gripping jaws 6-9 are interlinked to be displaced. Thus a square hole clamping body, which is gradually reduced or enlarged is formed. The utility model has the advantages that a square handle and a circular handle cutting tools are both can be quickly clamped to a central position; more than one hundred clamping tools can be replaced; a cutting tool which is as thinner as hair can be clamped.
Description
The present invention relates to the Machining Technology field, more particularly, relate to a kind of precise square orifices linkage fixture that can be widely used in the usefulness of the drill bit that clamps square shank milling cutter, reamer, screw tap and the garden handle of all size on various lathes and other machining equipments, milling cutter.
The employed chuck of existing various lathe, as lathe, drilling machine, milling machine, boring machine, Digit Control Machine Tool, machining center and other machining equipments, as employed chuck on electric hand drill, hand drill, the electric impact drill, garden shaft chisel in can only clamping more among a small circle, clamp the square shaft chisel of all size and be common to clamping less than 0.5 millimeter cutter, be a technical barrier since what years always, be not resolved all the time.For example, prior art does not also have to form a kind of like this technology so far, can clamp the centering that links of the square shaft chisel of many kinds of specifications and garden shaft chisel with a chuck.
The objective of the invention is to carry a kind of accurate interlock chuck of arch, this chuck can overcome the shortcoming of prior art, both can the side's of folder handle, also can press from both sides garden handle and polygonal, the cutter that hair is so thin also can accurately be clamped on the center fast.Novel structure, simple, clamping force is big, and a chuck can substitute original hundreds of anchor clamps, and it is convenient to change cutter, thereby enhances productivity greatly.The present invention also aims to change the conventional geometry of straight shank drill and straight shank milling cutter, become garden shape, can effectively prevent the disadvantage that cutter cutter in working angles skids easily and rotates into square.
The object of the present invention is achieved like this, constructing a kind of precise square orifices linkage fixture comprises: positioning and guiding body 1, gear jacket 2, connected body 3, positioning sleeve 4, main shaft 5, pushing block jaw 6-9, gear wrench 10, wherein, 56 taper shanks of main shaft 5 are fixed in the taper hole of machine tool chief axis or are connected on the electric hand drill main shaft or on the hand drill main shaft, other end end face evenly is provided with four positioning and guiding inclined-plane 51-54,42 endoporus of positioning sleeve 4, be enclosed within on the 55 outer gardens of main shaft 5, the internal thread 41 of positioning sleeve 4 links fixing with the external screw thread 17 of positioning and guiding body 1.Thereby the positioning and guiding inclined-plane 51-54 of main shaft 5 is contained between positioning sleeve 4 and the positioning and guiding body 1, makes the internal thread 29 of gear jacket 2 simultaneously, be enclosed within on the outer garden 26 of positioning and guiding body 1, make gear jacket 2 make garden Zhou Yundong, and can not do axially displaced.In two S shape square hole gathering sill 11-14 of positioning and guiding body 1, four pushing block jaw 6-9 evenly are housed, by 3 its location of control and the motions of a connected body.The axial square body 31-34 of connected body 3 is inserted among the axial square groove 22-25 of positioning and guiding body 1, the convex surface 63ABCD of four pushing block jaw 6-9 puts into to go to float in the cubic type groove that the square 39 of connected body 3 and 40-43 groove plane form and tangles, when the outer garden 11 of gear wrench 10 is inserted in 15 or 16 locating holes of positioning and guiding body 1, the umbrella flank of tooth 12 of gear wrench 10 coincide with the umbrella flank of tooth of gear jacket 2 27, when swing pinion wrench 10, make garden, original place Zhou Yundong with regard to driven gear overcoat 2, the internal thread 29 of gear jacket 2 drives the external screw thread 35-38 of connected body 3, make connected body 3 be with four pushing block jaw 6-9 to do axially displaced, because the guide-localization bevel angle 18-21 of the front end bevel angle 62ABCD of four pushing block jaw 6-9 and the internal protrusion of positioning and guiding body 1 matches, reaching the rear end guide-localization bevel angle 61ABCD of four pushing block jaw 6-9 and the guide-localization bevel angle 51-54 of main shaft 5 matches, so when four pushing block jaws move forward, can form a diminishing square hole clamping body, when four pushing block jaws move backward, will form a square hole body that amplifies gradually.
Implement precise square orifices linkage fixture of the present invention, have the following advantages: gripping range is big, not only can press from both sides garden shape, polygon, can also press from both sides squarely, the cutter that hair is so thin also can be clamped on the center by self-centering quickly and accurately, and clamping force is big, need not frequently change chuck because of changing cutter, a precise square orifices linkage fixture can substitute up to a hundred anchor clamps and use.
