Description
Technical field
The utility model relates to a kind of spanner, relates in particular to a kind of spanner that cylindrical component is used of installing and removing.
Background technology
At present, when in assembling, installing and removing cylindrical component, usually can run into situation about being not easy, cooperate tension with other part, install and remove difficulty, influence production efficiency like part with the part taking-up.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the spanner that the utility model provides a kind of mounting or dismounting cylindrical component easy to use to use, it has strong grip force, can be suitable for the cylindrical component of different-diameter size.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind ofly install and remove the spanner that cylindrical component is used, comprise and tighten axle, wrench body and collet, a said end of tightening axle is provided with tightens handle, and other end end face is provided with the positioning convex structure; Said collet comprises the portion of tightening and resilient clamp portion; Saidly tighten portion and resilient clamp portion is one-body molded; Wherein the portion of tightening is cylindrical, is provided with external thread structure in its outside, on the end face of the portion of tightening, is provided with and tightens the suitable locating hole of positioning convex structure on the axle; The said resilient clamp portion outside be a conical structure, and the inboard is the cylindrical structural of clamping cylindrical component; Said wrench body outside is provided with spanner handle; Inside is provided with through hole; Said through hole comprises the upper, middle and lower; Its middle and upper part for tighten the suitable axis hole of tightening of axle, middle position for collet on tighten the suitable internal thread hole of external thread structure of portion, the bottom be with collet on the suitable conical bore of conical structure of resilient clamp portion; The external thread structure of said collet is installed in the internal thread hole of wrench body, tightens axle and inserts tightening in the axis hole of wrench body, and the positioning convex structure insertion of its end face is tightened in the locating hole on the end surface.
During use, pull and tighten handle, make and tighten the axle rotation; Because being used of positioning convex structure and locating hole makes collet together rotate with tightening axle; Because being used of external thread structure and internal thread hole makes collet move axially along wrench body simultaneously; Because being used of conical structure and conical bore; Make cylindrical structural change in size in the resilient clamp portion; Clamp or unclamp the cylindrical component that places in it, can realize mounting or dismounting through pull lift action spanner handle to cylindrical component for the cylindrical component after clamping.
Said positioning convex structure is a hexagonal structure, and at this moment, locating hole then is suitable with it hexagonal hole.
The said axle of tightening is provided with handle hole, and the said handle of tightening is a cylinder, and the said handle of tightening inserts and to tighten in the handle hole on the axle; Tightening handle like this can conveniently take out, and can also in handle hole, move, so that the staff regulates use as required.
Said resilient clamp portion inboard is provided with the serration dental structure, and the serration dental structure can increase frictional force, produces very strong grip force, clamp cylinders shape part more securely.
The cylindrical structural size of the inboard clamping cylindrical component of said resilient clamp portion can be made plurality of specifications, makes it to become a grip assembly, the cylindrical component of the different sizes of convenient mounting or dismounting.
Beneficial effect: the spanner that the mounting or dismounting cylindrical component that the utility model provides is used, simple in structure, easy to use, have very strong grip force, can reliably working, and enhance productivity, and the versatility of this spanner is good.
