Abstract
The invention discloses a gear-shaving machine tool-changing wrench which comprises a handle and a ferrule. One end of the handle is fixedly connected with the ferrule, and a protrusion matched with the outer peripheral face of a nut is arranged on the inner side face of the ferrule. The applicable tool-changing wrench is designed and manufactured for a matched slotted nut, unsafe hidden danger is eliminated, and production cost is reduced.
Description
Technical field
The present invention relates to technical field, especially a kind of gear shaving machine tool changing spanner.
Background technology
During gear shaving machine tool changing dish, because cutterhead is generally at more than 10kg, and tool changing working space is little, workman bears a heavy burden large when changing cutterhead, it is special that cutterhead tightens slotted nut, must with beaing, strengthen workman's physical demands, secondly fastening strength is inadequate, and machine running process has the danger got loose.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of gear shaving machine tool changing spanner, structure is ingenious, easy to use.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of gear shaving machine tool changing spanner, comprise handle and lasso, handle one end is fixedly connected with lasso, and this lasso medial surface is provided with the projection coordinated with nut outer peripheral face.
Further, this lasso medial surface is provided with the projection of mating with the groove of slotted nut.
Compared with prior art, the present invention has the following advantages: manufacture and design applicable tool changing spanner for supporting slotted nut, eliminate unsafe hidden danger, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of gear shaving machine tool changing spanner as illustrated in fig. 1 and 2, comprise handle 3 and lasso 2, handle 3 one end is fixedly connected with lasso 2, and this lasso 2 medial surface is provided with the projection 21 coordinated with nut outer peripheral face.When nut 1 is slotted nut, this projection 21 is provided with several, puts with quantity corresponding respectively with the slot on slotted nut.Pull the tightening or loosening operation that handle 3 can complete nut 1, easy and simple to handle, practical.
This device can directly get loose, and tightens cutterhead slotted nut.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
