Abstract
The utility model discloses a three surface broachs, including the arbor, the arbor pull end, neck, front pilot, rear pilot and retriever has in proper order, the arbor three plane has, the front pilot all be equipped with main tooth at the aforesaid arbitrary planar both ends, the rear pilot all be equipped with the side tooth at the aforesaid surplus planar both ends. The utility model relates to an according to being processed part blank material and shape size, the shaping of required precision one -step refining be a high -efficient machine tooling cutter.
Description
Technical field
The utility model belongs to auto parts and components machined field, relates to a kind of surface broach, specifically a kind of three surface broaches.
Background technology
Broaching tool is the forming tool for broaching.Tool surface arranges cutter tooth more, and the size and dimension of each row's cutter tooth increases from incision end successively to cutting out end and changes.When broaching motion done by broaching tool, each cutter tooth just cuts certain thickness metal from workpiece, finally obtains required size and dimension.Broaching tool is usually used in batch and processes circular hole, splined hole, keyway, plane and profiled surface etc. in a large amount of production, and productivity ratio is very high.Common broaching tool is surface broach, round broach.
Now, due to blank material and the shape of part to be processed, need a kind ofly to process triangular shaped broaching tool, existing broaching tool can not disposablely machine, and now provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, provides a kind of three surface broaches.
The purpose of this utility model can be achieved through the following technical solutions:
Three surface broaches, comprise cutter shaft, and described cutter shaft has pull end, neck, front pilot, rear pilot and rear handle successively, and described cutter shaft has three planes; Described front pilot is equipped with main tooth at the two ends of above-mentioned any plane; Described rear pilot is equipped with side tooth at the two ends of above-mentioned residue plane.
Described cutter shaft axially through after handle have inside groove.
Described side tooth is between inside groove and main tooth place plane.
The beneficial effects of the utility model: the utility model three surface broach design consideration part to be processed blank material and shape size, required precision time processing are shaping, are a kind of efficient machine tools.
Accompanying drawing explanation
The utility model to be further described below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that.
Fig. 1 is the utility model schematic top plan view;
Fig. 2 is the utility model schematic side view.
Detailed description of the invention
As depicted in figs. 1 and 2, three surface broaches, comprise cutter shaft 1, cutter shaft 1 has pull end 2, neck 3, front pilot 5, rear pilot 6 and rear handle 4 successively, cutter shaft 1 cross section is triangle, and it has three planes, and front pilot 5 is equipped with main tooth 7 at the two ends of cutter shaft 1 any plane; The two ends that rear pilot 6 remains plane at cutter shaft 1 are equipped with side tooth 8, and side tooth 8 is between inside groove 9 and main tooth 7 place plane.Cutter shaft 1 axially through after handle 4 have inside groove 9.
The utility model precision, roughness requirements and heat treatment perform by general closed planar broaching tool processing criterion.The utility model three surface broach design consideration part to be processed blank material and shape size, required precision time processing are shaping, are a kind of efficient machine tools.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
