Abstract
The utility model discloses a combined sleeve, which comprises a hollow main sleeve, wherein a groove is arranged on an inner wall at a tail part of the main sleeve; a check ring is arranged on the tail part of the main sleeve; a rectangular handle connecting hole is arranged on the check ring; a plurality of sleeve units are arranged in the main sleeve, and have same structure; a convex strip is arranged on an outer wall at one end of each sleeve unit; a groove is arranged on an inner wall at one end of each sleeve unit; the sleeve unites are matched and sleeved with the grooves through the convex strips sequentially according to the size; the outer wall of each sleeve unit is matched with the inner wall of the previous sleeve in a sliding way; and corresponding springs are respectively arranged between the sleeve units in the main sleeve and the check ring. When being used, the combined sleeve is aimed at a bolt or a nut with corresponding size so as to be compressed downwards, so that unadapted sleeve units are shrunk towards an inner part of the combined sleeve until adapted sleeve units sleeve the bolt or the nut, and then the operation of fastening or disassembling can be carried out.
Description
Technical field
The utility model relates to a kind of machine tool, particularly a kind of combined sleeve.
Background technology
at present, tool sleeve on the market is all single specification, and bolt or the nut of the general use plurality of specifications of present a kind of equipment need be changed continually sleeve when work, operating efficiency is not high, under special environment, can't judge bolt or nut specification at some, more need repeatedly to change sleeve and remove the examination cover, and while carrying the sleeve of more specification, easily it is lost in to job site, stays potential safety hazard, inconvenience very.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and is easy to manufacture, and can adapt to the combined sleeve of plurality of specifications bolt or nut.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of combined sleeve, the master collet that comprises hollow, described master collet afterbody inwall is provided with groove, described master collet afterbody is provided with back-up ring, be provided with the handle connecting hole of rectangle on described back-up ring, be provided with some cartridge units in described master collet, described some cartridge unit shapes are identical, one end outer wall of described some cartridge units is provided with raised line, inwall is provided with groove, described some cartridge units are by size successively with raised line and groove fit suit, the outer wall of described each cartridge unit and upper level sleeve lining are slidably matched, be respectively arranged with corresponding spring between some cartridge units in described master collet and back-up ring.
As preferred version of the present utility model, under described some cartridge unit free states, the small sleeve unit protrudes from the upper level sleeve.
As preferred version of the present utility model, the quantity of described some cartridge units is 3.
As preferred version of the present utility model, described some cartridge units are Hexagonal jacket.
As preferred version of the present utility model, it is 6 with groove quantity that the raised line quantity of described cartridge unit is 6.
As preferred version of the present utility model, the raised line of described cartridge unit and groove are arranged on the center line of cartridge unit side.
As preferred version of the present utility model, the length of described groove is less than 1/2nd of cartridge unit length, and the length of described groove is greater than the length of raised line.
As preferred version of the present utility model, the gap between described adjacent cartridge unit is 0.2mm, and the fit clearance between described raised line and groove is 0.5mm.
A kind of combined sleeve of the utility model is set in together the cartridge unit of plurality of specifications, bolt or the nut that only it need be aimed to corresponding size during use are pressed down, make unconformable cartridge unit to the combined sleeve internal contraction, until the cartridge unit adapted to entangles bolt or nut, can carry out fastening or disassembling section.A kind of combined sleeve of the utility model effectively solves existing sleeve can only be for the technical problem of a kind of sized bolt or nut, and easy to use, simple in structure, is easy to manufacture, and has practical reference value.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of combined sleeve of the utility model.
Fig. 2 is the side-looking structural representation of a kind of combined sleeve of the utility model.
The structural representation of the cartridge unit that Fig. 3 is a kind of combined sleeve of the utility model.
Mark in figure: 1 is master collet, and 2 is back-up ring, and 3 is connecting hole, and 4 is cartridge unit, and 5 is raised line, and 6 is groove, and 7 is spring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of combined sleeve of the utility model as shown in Figure 1, the master collet 1 that comprises hollow, described master collet 1 afterbody inwall is provided with groove, described master collet 1 afterbody is provided with back-up ring 2, be provided with the handle connecting hole 3 of rectangle on described back-up ring 2, be provided with some cartridge units 4 in described master collet 1, described some cartridge units 4 shapes are identical, one end outer wall of described some cartridge units 4 is provided with raised line 5, inwall is provided with groove 6, described some cartridge units 4 coordinate suit with raised line 5 and groove 6 by size successively, the outer wall of described each cartridge unit and upper level sleeve lining are slidably matched, be respectively arranged with corresponding spring 7 between some cartridge units 4 in described master collet 1 and back-up ring 2.
In a kind of combined sleeve of the utility model, for being suitable for narrow and small working space, some cartridge units 4 are designed to small sleeve unit under free state and protrude from the upper level sleeve as shown in Figure 1.Consider that manufacturing process is simple and use stable factor, the quantity of some cartridge units 4 is designed to 3, and cartridge unit 4 is designed to Hexagonal jacket.Not fragile while for the assurance cartridge unit, coordinating reliable and torsion, its raised line and groove quantity all are made as 6.Easy to process even with stress distribution for manufacturing, the raised line of cartridge unit and groove design are on the center line of cartridge unit side.For reducing the required precision of part processing, the Design of length of groove is to be less than 1/2nd of cartridge unit length, and the Design of length of groove is the length that is greater than raised line.Consider the flexibility when convenience of assembling and combined sleeve are used, the gap design between adjacent cartridge unit is 0.2mm, and the fit clearance between raised line and groove is designed to 0.5mm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
