Abstract
The utility model relates to an annular six-claw spanner. The annular six-claw spanner is composed of a spanner frame and a handle, the handle is connected at the lower end of the spanner frame in a coaxial mode, the spanner frame and the handle are made as one, the spanner is annular, and three to six positioning claws are distributed evenly at the inner edge of the spanner frame in a spaced mode. The annular six-claw spanner is designed according to a shape of a locknut, the spanner is designed to be annular, and six positioning claws are distributed evenly at the inner edge of the spanner frame, the positioning claws are respectively arranged inside a tooth space on the locknut and are matched with the tooth space in a mutually tightness compression joint mode, and therefore hook spanner flyout caused by trip between the spanner and the tooth space on the locknut is avoided, and production safety hidden danger is reduced.
Description
Technical field
The utility model belongs to the wrench technical field of tools, especially a kind of ring-type six pawl spanners.
Background technology
Emery wheel has been widely used in grinding machine as a topmost class grinding tool in grinding, and above-mentioned emery wheel normally is fixed on grinding machine by the locking nut that is complementary with the emery wheel size, and above-mentioned syndeton can guarantee the stability of emery wheel when operation.But emery wheel belongs to wear-out part, need to regularly change, and usually use hook spanner to dismantle locking nut in the process of changing emery wheel, dropout between the locking nut teeth groove that is very easy to occur being shaped with on hook spanner and locking nut and the accident that hook spanner flies out occurs has brought certain hidden danger for operator's personal safety.
In addition, usually be shaped with a locating detent on above-mentioned hook spanner, this locating detent independent stressed during operation, not only limited to stressed degree, and the damaged of locating detent easily occurs and rupture, need often welding and maintenance to use reluctantly, had a strong impact on employee's production efficiency, also increased unnecessary production cost simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of simple in structure, ring-type six pawl spanners that can closely fasten with the locking nut groove are provided.
The technical solution adopted in the utility model is:
A kind of ring-type six pawl spanners are comprised of spanner frame and handle, and spanner frame its lower end links together with handle is coaxial, and spanner frame and handle are integrated to be made, and described spanner frame is that ring-type and its inner rim are shaped with 3 ~ 6 locating detents uniformly at intervals.
And the number of described locating detent need to be complementary with the teeth groove quantity of nut.
The utility model advantage and good effect are:
1, this ring-type six pawl spanners design according to the locking nut shape, the spanner frame is designed to ring-type, and be shaped with uniformly at intervals 6 locating detents at spanner frame inner edge, this locating detent lay respectively in locking nut teeth groove on locking nut and with teeth groove tight press fit mutually, avoid thus the dropout between the teeth groove on spanner and locking nut and hook spanner has occured flying out, reduced production safety hidden danger.
2, this ring-type six pawl spanners will be dismantled the mean forced that locking nut produces and be dispersed on 6 locating detents, avoided single locating detent over-stressed and situation damaged and fracture occurs, avoided thus spanner to be easy to damage and needed to change, repair phenomenon frequently, disposablely solved production cost output, reduce production costs, improve the rate of starting of machinery, guaranteed the normal production of each production line.
Description of drawings:
Fig. 1 is structural front view of the present utility model;
Fig. 2 be in Fig. 1 A-A to sectional view.
The specific embodiment:
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of ring-type six pawl spanners are comprised of spanner frame 1 and handle 3, and spanner frame its lower end links together with handle is coaxial, and spanner frame and handle are integrated to be made.
Innovative point of the present utility model is:
Described spanner frame is that ring-type and its inner rim are shaped with 3 ~ 6 locating detents 2 uniformly at intervals.
The number of above-mentioned locating detent need to be complementary with the teeth groove quantity of nut, and in the present embodiment, the locating detent number is 6.
Using method of the present utility model is:
With the teeth groove corresponding embedding one by one on 6 locating detents in the spanner frame and locking nut, rotating spanner, this locating detent lay respectively in locking nut teeth groove on locking nut and with teeth groove tight press fit and drive locking nut and separate with emery wheel mutually.
