Abstract

The utility model belongs to machinery hardware tools, particularly relates to an outer-hexagon socket spanner with the adjustable size. The outer-hexagon socket spanner resolves the problem that the head of a bolt and the head of a nut are abraded, so that the bolt and the nut can not be fastened or disassembled normally. The outer-hexagon socket spanner is mainly composed of a pressing nut, an expandable barrel clamp, a rotating handle and a socket with an inner cone. The outer-hexagon socket spanner with the adjustable size is characterized by being formed by the expandable barrel clamp of an inner-hexagon structure and the inner conical socket matched with the expandable barrel clamp. The outer-hexagon socket spanner resolves the problem that the bolt with the abraded head and the nut with the abraded head cannot be screwed through a common socket spanner, and is particularly suitable for disassembling or screwing the bolt and the nut which are used for various machines and equipment and are common in life, wherein the outer hexagon of the bolt and the outer hexagon of the nut are abraded.

Description

The adjusting external hexagonal socket wrench

One, technical field

The utility model relates to a kind of being used for the screw rod in the machine components, nut is carried out instrument fastening or dismounting, specifically a kind of adjusting external hexagonal socket wrench.

Two, background technology

Present state-of-the-art technology: Chinese patent application number: 201130236341 external hexagonal socket wrench, be used for twisting bolt or the nut that depression is slightly arranged, it is compared with traditional external hexagonal sleeve, increased the function of twisting recessed bolt or nut, but since in life and in producing common bolt or nut the outer-hexagonal not quick detachable and problem of tightening that (corner angle are unclear) produce of skidding do not relate to.

Three, utility model content

The technical problem that-the utility model solves is, provided preferably solution for the bolt of often meeting or nut the outer-hexagonal not quick detachable and problem of tightening that (corner angle are unclear) produce of skidding.

The utility model: the external hexagonal socket wrench of adjusting, but mainly form by clamp nut breathing collet chuck, rotary handle and with the sleeve of inner cone.

In the described clamp nut screw thread is arranged, there is circular hole the centre, and the external screw thread on its feature screw thread and the sleeve is complementary, and middle Circularhole diameter is greater than the interior hexagonal circumscribed circle at expansible collet chuck top.

But described breathing collet chuck, to clamp the outer-hexagonal screw rod, the parts of nut, the top profile that it is characterized in that collet chuck is cone, the size of outer cone can be adjusted, endoporus is hexagon, hexagonal size is according to master screw, the nut size is made serial model No., the phase feature is that distance between three couples of relative edges in the interior hexagonal is greater than master screw, nut, be shaped with the breathing groove in cone, these breathing grooves are distributed on the cone, and its quantity is 12, wherein have six channel openings to coincide in six ribs of front end and interior hexagonal, but its effect is the face that makes 6 breathing of interior hexagonal formation, is used for clamping screw rod and the nut of outer-hexagonal shape.

Described rotary handle is the handle that makes the box spanner rotation, can be made into various shape, can be circular, also can be square or other shape.

Described sleeve with inner cone, but be the part that is used for fixing the breathing collet chuck and collet chuck is shunk, be characterised in that in the inside of outside cylinder and make up big and down small internal taper hole, but the tapering outline is less than the male cone (strobilus masculinus) tapering of breathing collet chuck, the size capable of regulating, the outside upper half part of sleeve is external screw thread, is complementary with the internal thread of clamp nut.

But the utility model is the interior hexagonal clamping device that utilizes the breathing collet chuck with interior hexagonal structure and form adjusting the inner conical drogue that cooperates with it, by clamp nut but the breathing collet chuck is compressed in the sleeve that inner cone is arranged, because the inner cone of sleeve is less than the outer cone of collet chuck, when collet chuck moves down, the sleeve inner face evenly inwardly pushes collet chuck, the interior hex surface of collet chuck is dwindled, thereby outer six clampings with screw rod, nut efficiently solve bolt or nut dismounting problem that outer-hexagonal skids.

The utility model is fit to dismounting or screw rod and the nut of outer-hexagonal wearing and tearing is installed very much, solved the problem that box spanner commonly used can't turn this screw rod, nut, be specially adapted to various machines, equipment, and life in common the outer-hexagonal screw rod, the nut dismounting that are worn or tighten.

Below in conjunction with accompanying drawing the utility model is further specified.

Five, the specific embodiment

Embodiment 1, referring to Fig. 1～Figure 12, adjusting external hexagonal socket wrench, clamp nut wherein (1), interior circular hole (2) on the clamp nut, but breathing collet chuck (3), inner hexagonal hole (4), breathing groove (5), rotary handle fixing hole (6), rotary handle (7), with the sleeve (8) of inner cone, more than all the available metal material make.

But after the available tool steel of breathing collet chuck (3) or the processing of other hard alloy steel, by heat treatment its hardness is improved again, hardness requirement when guaranteeing its work, the top sharp processing of collet chuck becomes cone, the size of outer cone can be adjusted, but be generally 5～10 degree breathing collet chuck endoporus and be processed into hexagon (4), hexagonal two-phase opposite side distance is made serial model No. from size according to master screw, nut opposite side size, but the relative edge's distance in the interior hexagonal of breathing collet chuck is than master screw, the large 0.5～2mm of nut.Namely also make corresponding model with respect to M5, M6, M8, M10, M12...... the utility model of screw rod, nut.For example the hex nut two-phase opposite side distance of screw rod is from being 19mm, but the distance of the relative edge in the hexagonal can be made into 21mm in the breathing collet chuck, by that analogy.

But process breathing groove (5) in breathing collet chuck cone, these breathing grooves are distributed on the cone, its quantity is 12, wherein there are six channel openings to coincide in six ribs of front end and interior hexagonal, other six uniform grooves seal, but its effect is the interior hexagon endoporus (4) that makes 6 breathing of interior hexagonal formation, is used for clamping screw rod and the nut of outer-hexagonal shape.

Sleeve (8) with inner cone, but be the part that is used for fixing the breathing collet chuck and collet chuck is shunk, be processed into up big and down small internal taper hole in the inside of outside cylinder, generally be about 5～10 degree, but about male cone (strobilus masculinus) tapering 0.5～1 degree of tapering less than the breathing collet chuck, the outside upper half part of sleeve processes external screw thread, is complementary with the internal thread of clamp nut.

The course of work: the turret head of the screw rod that will turn (9) inserts in the inner hexagonal hole of the present utility model (4), clamp nut (1) screws up with a wrench, this moment clamp nut (1) but inner top surface with the pressure that faces down on the breathing collet chuck (3), but the male cone (strobilus masculinus) angle of breathing collet chuck (3) is greater than the tapering of contacted sleeve with inner cone (8) with it, the inner conical surface of sleeve is to the collet chuck application of force, the interior hexagon face (4) of collet chuck is inwardly dwindled, reach the effect of clamping screw, turn rotary handle (7) this moment again, screw rod can be turned.
