Description
Technical field
The utility model belongs to ore dressing service kit technical field, is specifically related to a kind of adjustable spanner that the ball mill pinion is used of changing.
Background technology
The existing adjustable spanner that is used to change the ball mill pinion adopts two parallel surfaces, one jiao to add a corresponding plane or moment of torsion is transmitted at three angles, and to bear the force few because of nut, and local pressure is excessive, is easy to damage the planform of nut, and nut was lost efficacy.And the back-up wrench that uses in groups, though it adopts 6 points (angle) to transmit moment of torsion, it carries trouble, the replacing assembly that need not stop during use, and complex operation, and lose easily.There is a kind of adjustable spanner to adopt the taper thread drive mechanism, three slide blocks of the general drive of taper thread transmission, its cross section is circular, after stressed, in circular hole, relatively rotate easily, produce additional force and act on taper thread and parts on, cause structural failure or life-span to descend.
Summary of the invention
The purpose of this utility model provides a kind of simple to operate, long service life, adjustable spanner that efficient is high, is specially adapted to change the ball mill pinion.
The purpose of this utility model realizes by following technical proposals:
Adjustable spanner of the present utility model is characterized in that by six screw thread pulling teeth, therewith six main covers that the screw thread pulling teeth is slidingly connected, the pair cover that main therewith cover is rotationally connected, the nut cap that main therewith external threading connects, the ratchet that main therewith set upper side is connected connects square column and forms
The cross section of described screw thread pulling teeth is square, and the bottom of this screw thread pulling teeth has the 120 degree angles that adapt with outer-hexagonal nut outline, and the top of this screw thread pulling teeth is provided with inside tapered thread,
The ring set that cover and overcoat were formed in described main cover was served as reasons, the set upper side is provided with square hole in described, this square hole is connected the square column lower end with described ratchet and plugs, described ring set bottom along the circumferential direction evenly tilts to be provided with six square grooves, this square groove and described screw thread pulling teeth are slidingly connected, described overcoat top is provided with external screw thread, and this external screw thread and described nut cap are connected with a joggle
The lower end of described secondary cover is provided with outer cone thread, inside tapered thread on this outer cone thread and the described screw thread pulling teeth is connected with a joggle, the outer surface of described secondary cover is top minor diameter, bottom major diameter stepped surfaces, the inner surface and the described lining the outer surface of of this secondary cover are rotationally connected, large diameter outer surface of this secondary cover is rotationally connected with the inner surface of described overcoat, this secondary minor diameter outer surface that overlaps be knurled surface and with described nut cap endoporus matched in clearance.
The tapering of described inside and outside taper thread is 20～60 degree.
Press the adjustable spanner of said structure assembling.By the revolute pair cover, drive six main square grooves that put in screw thread pulling teeth while edge and move up and down, spend outer hexagonal sizes that angle surrounded thereby regulate, realization spanner adjusting purpose by 120 of six screw thread pulling teeth lower ends.
The beneficial effects of the utility model are: easy to adjust, simple in structure, radial dimension is little, and compact conformation is easy to carry, and the scope of application is big.This spanner adopts six pulling teeth, and nut 6 points (angle) are stressed, and stressed being evenly distributed born torque capability and increased.It is square that the pulling teeth cross sectional shape adopts, when pulling teeth when its axis produces undesired moment of torsion, can not be delivered to spanner inside, avoid causing spanner to damage or the life-span reduces.
