Abstract

The utility model relates to a machine-used pentagon sleeve, which comprises a sleeve head and a sleeve tail and is characterized in that the working part of the sleeve is a paragon hole; the joints of the sleeve tail and the driving machine match, which can be a square hole or a six-edge column. The sleeve is used in the pneumatic or electric assembly occasion and can safely and high-efficiently screw down or screw off the pentagon head bolt or nut. At the narrow point of the spanner space, the sleeve can be used to conveniently screw the pentagon bolt or nut.

Description

Machine is with five jiaos of sleeves

One, technical field

The design belongs to a kind of assembling instrument, in particular for pneumatic or electronic machine assembly tool.

Two, background technology

For preventing illegal repacking or dismounting violating the regulations, the important thread connection place on some equipment, facility or the vehicles (for example motorcycle) partly begins to adopt five angle head Bolt Connection.Simultaneously, the craft spanner that is applicable to five angle head bolts has been arranged.But on assembly line, also there is not the suitable machine tool that is complementary with coupling head driving device.

Three, summary of the invention

The design's purpose is to design the sleeve that machine that a kind of and coupling head driving device be complementary is used, and when tightening or unloading five angle head bolts with it on assembly line, can adapt to safe, needs efficiently.

What realize purpose of design is a kind of machine with five jiaos of sleeves, it includes sleeve head and sleeve afterbody, it is characterized in that: the working portion of sleeve head is pentagon hole (obviously, the bolt head of it and five angle head bolts is complementary), and the coupling head of sleeve afterbody and driving device is complementary.Driving device can be electronic, also can be pneumatic (for example: pneumatic trigger).

The design's superiority is:

1, the afterbody of this sleeve with after the coupling head (tenon or chuck) of driving device connects, again the pentagon borehole jack of its head working portion on corresponding bolts head (or nut), can tighten apace or the bolt of back-outing (or nut).To realize safety, purpose efficiently.

2, in " spanner space " narrow workplace, this sleeve corresponding bolt (or nut) of also tightening easily or back-out.

Five, the specific embodiment

Embodiment 1 (mainly in conjunction with the accompanying drawings 1,2,3):

Referring to Fig. 1, Fig. 2 and Fig. 3.The working portion of sleeve head 1 is pentagon hole 3; At this sleeve afterbody 2 individual square hole 4 is arranged.Even the square hole of this afterbody 4 mates with the square tenon of the clutch end of driving device---also the time spent, this side's tenon is inserted in the described square hole 4.

Embodiment 2 (mainly in conjunction with the accompanying drawings 4,5);

Referring to Fig. 4 and Fig. 5.The working portion of sleeve 1 head is pentagon hole 3; This sleeve afterbody 2 ' be hexagon.Even this afterbody 2 ' be complementary---also time spent with the chuck of the clutch end of driving device, the sleeve afterbody 2 of described hexagon ' lived by this chuck clamping.

In above-mentioned two embodiment, the afterbody of sleeve with after pneumatic wrench or chuck output (square tenon or chuck) connect, again the pentagon borehole jack of its working portion on corresponding five angle head bolts (or nut), start pneumatic wrench then or rotate chuck, by the rotating of pneumatic wrench or chuck, can tighten safely and fast or the bolt of back-outing (or nut).

In above-mentioned two embodiment, the coupling part between their sleeve head and the sleeve afterbody can design, process different length as required; Also have in the bottom in the pentagon hole of described sleeve head a circular hole 5 (except at process aspect for processing the pentagon hole provides convenience, be screwed into, when back-outing pentagon nut, the space that holds the screw portion that stretches out arranged also).

Claims

1, a kind of machine is with five jiaos of sleeves, and it includes sleeve head (1) and sleeve afterbody, it is characterized in that: sleeve head (1) is pentagon hole (3), and the coupling head of sleeve afterbody and driving device is complementary.

2, machine according to claim 1 is with five jiaos of sleeves, and it is characterized in that: described sleeve afterbody (2) has individual square hole (4).
