Abstract
The invention relates to the field of gear machining equipment, in particular to a cutting device of a gear hobbing machine. The cutting device comprises a hobbing-cutter shaft and a hobbing cutter, wherein a plurality of protruding balls are arranged in the middle of the hobbing-cutter shaft which is provided with a cutter sleeve, a plurality of grooves matched with the balls for use are formed in the cutter sleeve, the cutter sleeve is provided with a notch used for fixing the hobbing cutter, and the side face of the cutter sleeve is provided with bolts used for fastening the hobbing cutter. The cutting device is simple in structure and ingenious in design; thus, in a using process, once the hobbing cutter is damaged, only the cutter sleeve needs to be replaced, the whole hobbing-cutter shaft does not need to be replaced, and cost is saved. A new technical scheme is adopted, and the cutting device is convenient to popularize and use.
Description
Technical field
The present invention relates to gear machining apparatus field, particularly the topping machanism on a kind of gear-hobbing machine.
Background technology
Current existing gear-hobbing machine topping machanism, comprises hobboing cutter main shaft and hobboing cutter, and the thick section in middle part of hobboing cutter main shaft has square hole along diameter of axle direction, and hobboing cutter plug-in mounting is fixed in square hole.The topping machanism of this structure, in the process of using, once for the fixedly position damage of hobboing cutter, just need to change whole hobboing cutter main shaft, has improved cost like this.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, the topping machanism on a kind of gear-hobbing machine that provide a kind of simple in structure, reasonable in design, can reduce costs.
For achieving the above object, the technical solution used in the present invention is:
Topping machanism on a kind of gear-hobbing machine of the present invention, comprise cutter shaft and hobboing cutter, the middle part of cutter shaft is provided with the ball of a plurality of projections, cutter shaft is provided with broach shell, the inside of broach shell is provided with a plurality of grooves that are used in conjunction with ball, described broach shell is provided with for the fixing recess of hobboing cutter, and the side of broach shell is provided with the bolt for fastening hobboing cutter.
Further, described hobboing cutter is provided with protective jacket, and protective jacket is fixedly connected with broach shell.
Further, described ball is for having flexible rubber ball.
Further, the bilateral symmetry of described cutter shaft is provided with the block that prevents broach shell landing, and block is fixedly connected with broach shell with cutter shaft by bolt.
Adopt after said structure, beneficial effect of the present invention is: the topping machanism on a kind of gear-hobbing machine of the present invention, comprise cutter shaft and hobboing cutter, the middle part of cutter shaft is provided with the ball of a plurality of projections, cutter shaft is provided with broach shell, the inside of broach shell is provided with the grooves that a plurality of and ball are used in conjunction with, and described broach shell is provided with for the fixing recess of hobboing cutter, and the side of broach shell is provided with the bolt for fastening hobboing cutter.
The present invention is simple in structure, it is ingenious to design, and in the process of using, once hobboing cutter damages, also only need to change broach shell, and without changing whole cutter shaft, so just provide cost savings like this.This is a kind of new technical scheme, is convenient to promote the use of.
Accompanying drawing explanation
Accompanying drawing described herein is to be used to provide a further understanding of the present invention, forms the application's a part, but do not form inappropriate limitation of the present invention, in the accompanying drawings:
Fig. 1 is structural representation of the present invention;
Description of reference numerals:
1, cutter shaft; 2, hobboing cutter; 3, ball; 4, broach shell; 5, bolt;
6, protective jacket, 7, block.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the present invention in detail, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1, topping machanism on a kind of gear-hobbing machine of the present invention, comprise cutter shaft 1 and hobboing cutter 2, the middle part of cutter shaft 1 is provided with the ball 3 of a plurality of projections, cutter shaft 1 is provided with broach shell 4, the inside of broach shell 4 is provided with the grooves that a plurality of and ball 3 are used in conjunction with, and described broach shell 4 is provided with for the fixing recess of hobboing cutter 2, and the side of broach shell 4 is provided with the bolt 5 for fastening hobboing cutter 2.
By a preferred embodiment of the present invention, described hobboing cutter 2 is provided with protective jacket 6, and protective jacket 6 is fixedly connected with broach shell 4.
By a preferred embodiment of the present invention, the bilateral symmetry of described cutter shaft 1 is provided with the block 7 that prevents broach shell 4 landings, and block 7 is fixedly connected with broach shell 4 with cutter shaft 1 by bolt.
The present invention is simple in structure, it is ingenious to design, and in the process of using, once hobboing cutter damages, also only need to change broach shell, and without changing whole cutter shaft, so just provide cost savings like this.This is a kind of new technical scheme, is convenient to promote the use of.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
