Abstract
The utility model discloses a detachable backward broach which comprises a knife handle and a broach head. A cutting sleeve rod portion is arranged on the lower end portion of the knife handle, a baffle shoulder is arranged on the root portion of the cutting sleeve rod portion, a tabular embedded clamping head is arranged on the lower end portion of the cutting sleeve rod portion, and two symmetrically-arranged embedded clamping grooves are formed in the root portion of the embedded clamping head. A cutting sleeve hole is formed in the core portion of the broach head, two symmetrically-arranged embedded clamping blocks are arranged on the lower end portion of the cutting sleeve hole, the embedded clamping blocks are inserted in the embedded clamping grooves, and the upper surface of the broach head is connected with the baffle shoulder of the cutting sleeve rod portion in an abutting mode. According to the detachable backward broach, the broach head is assembled and fixed on the knife handle mainly through matching of the embedded clamping blocks and the embedded clamping grooves, and when the broach head is rotated and the embedded clamping blocks recede from the embedded clamping grooves, the broach head can be detached from the knife handle. Therefore, the detachable backward broach can achieve free and quick detachment and installation, in the process of broach replacement, a worker only needs to replace the broach head and does not need to replace the knife handle, the detachment and installation are convenient, and work efficiency can be improved effectively.
Description
Technical field
The utility model relates to the cutting tool technical field, relates in particular to a kind of detachable broaching tool.
Background technology
As a kind of important machining tool, broaching tool is widely used in the processing such as circular hole, spline and keyway; As a kind of important kind of broaching tool, the application of falling the broaching tool is also extensive in the extreme.
Existing broaching tool generally adopts integral structure, and namely shank portion and the broaching tool head of broaching tool are divided into an integral body, and both are non-dismountable; In the cutting process of reality, above-mentioned integral type is fallen broaching tool and is had following defective, and for example: in the process of tool changing, the palpus of falling broaching tool integral body is changed together, changes inconvenient and affects operating efficiency.
The utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art a kind of detachable broaching tool that falls, the broaching tool that should fall can be dismantled as required freely, in the process of tool changing, operating personnel need not to change handle of a knife and only need change the broaching tool head and get final product, and dismounting is very convenient and can effectively increase work efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of detachable broaching tool, the broaching tool head that includes handle of a knife and removably be installed in the bottom of handle of a knife, the bottom of handle of a knife is provided with the card sleeved rod portion, the root of card sleeved rod portion is provided with shoulder block, the bottom of card sleeved rod portion is provided with the inlay card head of flat, and the root of inlay card head offers two inlay card grooves that are arranged symmetrically with; The corresponding card of the core of broaching tool head sleeved rod portion offers the cutting ferrule hole of running through fully, the bottom in cutting ferrule hole is provided with two inlay card pieces that are arranged symmetrically with, the inlay card head is intercalated in the cutting ferrule hole and extends to the below of the lower surface of broaching tool head, the inlay card piece is intercalated in the inlay card groove, the upper surface of broaching tool head and the shoulder block butt that blocks sleeved rod portion.
The beneficial effects of the utility model are: a kind of detachable broaching tool described in the utility model, the broaching tool head that includes handle of a knife and removably be installed in the bottom of handle of a knife, the bottom of handle of a knife is provided with the card sleeved rod portion, the root of card sleeved rod portion is provided with shoulder block, the bottom of card sleeved rod portion is provided with the inlay card head of flat, and the root of inlay card head offers two inlay card grooves that are arranged symmetrically with; The corresponding card of the core of broaching tool head sleeved rod portion offers the cutting ferrule hole of running through fully, the bottom in cutting ferrule hole is provided with two inlay card pieces that are arranged symmetrically with, the inlay card head is intercalated in the cutting ferrule hole and extends to the below of the lower surface of broaching tool head, the inlay card piece is intercalated in the inlay card groove, the upper surface of broaching tool head and the shoulder block butt that blocks sleeved rod portion.The utility model mainly is fixed on handle of a knife by cooperating between inlay card piece and the inlay card groove with the broaching tool head, when rotating the broaching tool head and so that inlay card piece when recessing the inlay card groove, the broaching tool head can disassemble from handle of a knife.Comprehensive above-mentioned situation as can be known, the utility model can realize freely and rapidly dismounting that in the process of tool changing, operating personnel need not to change handle of a knife and only need change the broaching tool head and get final product, dismounting is very convenient and can effectively increase work efficiency.
