Abstract
The utility model relates to a spanner used for fastening the inner hexagon taper hole bolt, which overcomes the defects of poor centering performance, inconvenient operation, a big number of spanners, easy abrasion and easy damage to bolts of the existing inner hexagonal bolts. The utility model is characterized in that the end of the rod is made into a six frustum of which the bottom margin is divided into three dimension series. When used, the work of fastening and loosening the bolts in the range of the M4-M30 can be completed by three spanners, and in addition, the utility model has the advantages of long service life, reliable work, high efficiency, simple processing, and no damage to bolts, which is particularly suitable for mechanization.
Description
The utility model belongs to spanner and makes the field.The inner hexagonal hole that requires when now the inner hexagon spanner that uses is worked to aim at the screw with inner hexagonal hole could insert, extract from the inner hexagonal hole of soket head cap screw very inconveniently again after angle of rotation, the inner hexagonal hole of aiming at soket head cap screw just can carry out next working cycles more difficultly.Also being different for the employed inner hexagon spanner of the screw of different size in addition, promptly must be that a kind of screw of specification will have the soket head cap screw of how many kinds of specification that the how many kinds of inner hexagon spanner must be arranged with one inner hexagon spanner.Many inconvenience have been brought to work like this.
The utility model is exactly to use inconvenient defective in order to overcome inner hexagon spanner, improves its serviceability and the interior hexagonal taper hole screw wrench with new construction that designs.Structure of the present utility model is like this: the hexagonal pyramid platform is made at the two ends that bend to 90 ° of degree rod members, and outwards shown in figure (1a), (1) is the hexagonal pyramid platform to small end, and (2) are the rod members that bends to 90 ° of degree, and figure (1b) is the side view of spanner.The utility model was suitable for to as if in hexagonal taper hole screw (having declared patent) the utility model be divided into three series, three series with hexagonal pyramid platform base a get different numerical value correspondingly in three series L also to there being different length to distinguish.
The utility model is for M4--M6; M8--M16; Hexagonal taper hole screw in 14 kinds in three series of M18--M30, only the fastening and pine that just can solve all screws with the spanner of three different sizes is unloaded work, for all screws in the series, only with once finishing spanner fastening and pine is unloaded work.Be shown in the series as figure (2b).Though the screw of multiple different size is arranged, the base a and the cone angle of its taper hole are identical.So, only spanner (shown in Fig. 2 a) is got final product with same for screw with different size in a series of.Only spanner inserts the degree of depth difference of screw taper hole.
The utility model can also be made the form of straight-bar: an end frustum, the other end have the screw thread that can be fixed on the power source (as Fig. 3 a), keyway (as Fig. 3 b), spline etc. (as Fig. 3 c)
Adopt the utility model, can significantly reduce the quantity of inner hexagon spanner.As only unloading work with the 3 fastening and pines that can separate all screws to spanner for 14 kinds of screws of M4--M30.
The service life of adopting the utility model can greatly improve spanner.After the spanner wearing and tearing.As long as the reconditioning spanner frustum of a pyramid.
Adopt the utility model, can make the interior hexagonal taper hole of spanner and screw fully identical, improve screw life-span and functional reliability.
Adopt the utility model, can make the very fast location of spanner and screw taper hole, improved operating efficiency greatly.
The utility model adopts with inner hexagon spanner identical materials and technology and makes, different only getting final product at the two ends of the six square bar spares needed cone angle of processing cost utility model; For the spanner of straight-bar spare form, an end is processed into the hexagonal pyramid platform, and the other end is processed into screw thread, keyway, spline etc. and gets final product, and its technology also is identical with material and inner hexagon spanner.
Claims (5)
1, a kind of spanner that is used for fastening interior hexagonal taper hole screw, the end that it is characterized in that rod member is the hexagonal pyramid platform, and the hexagonal length of side difference with on the hexagonal pyramid platform base is divided into three series to spanner, and the cone angle of six terrace with edges of each series all is identical.
2, interior hexagonal taper hole screw wrench according to claim 1 is characterized in that rod member can be a hexagonal prism, also can be cylinder.
3, interior hexagonal taper hole screw wrench according to claim 1 is characterized in that an end of rod member is made the hexagonal pyramid platform, and the other end is made screw thread, keyway, spline, is used to connect power source.
