Abstract
The invention discloses a gear-shaving machine tool-changing wrench device which comprises a connecting rod and a ferrule. The connecting rod coincides with the axis of the ferrule, the lower end of the connecting rod is fixedly connected with the ferrule, and a square table is arranged at the upper end of the connecting rod. A protrusion matched with the outer peripheral face of a nut to be operated 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 wrench device.
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 wrench device, 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 wrench device, comprise connecting rod and lasso, the dead in line of connecting rod and lasso, lower end is fixedly connected with lasso, and upper end is provided with square platform; The medial surface of this lasso is provided with the projection coordinated with nut outer peripheral face to be operated.
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 wrench device as illustrated in fig. 1 and 2, connecting rod 2 and lasso 1, the dead in line of connecting rod 2 and lasso 1, lower end is fixedly connected with lasso 1, and upper end is provided with square platform 21; The medial surface of this lasso 1 is provided with the projection 11 coordinated with nut outer peripheral face to be operated.
This lasso 1 medial surface is provided with the projection 11 of mating with the groove of slotted nut.
Common spanner can be used to be clamped and connected the square platform 21 of bar 2 upper end, lasso in this device 1 to be set in and to treat on affected nut, pull the tightening or loosening operation that spanner 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.
