Abstract
The invention relates to a flat counterbore. The flat counterbore comprises a cutter rod and a cutter bit; the cutter rod includes a shank, a table shoulder and a cutter bit connecting rod; the cutter bit connecting rod is provided with a cutter bit connecting structure; the cutter bit connecting structure is three planes connected with each other; the three planes are a first plane, a second plane and a third plane in sequence; included angles between the adjacent planes are 120 degrees; one end of the first plane extends to the tail end of the cutter bit connecting rod; the second plane and the third plane are both axially limited by the cutter bit connecting rod at two ends of the axial direction of the cutter bit connecting rod; the cutter bit is cylindrical, and is axially provided with a through hole; a vertical surface matched with the first plane, the second plane and the third plane is arranged on the side wall of the through hole; blades are arranged on one side of the cutter bit; and multiple blades are provided. The flat counterbore can quickly machine workpieces to improve the working efficiency of workers.
Description
Technical field
The present invention relates to machining technology field, more particularly to a kind of counterbore.
Background technology
When using the product with labyrinth such as riveting assembling and bolt connection assembling automobile, aircraft, some rivets
Hole and screw hole can only be arranged in the structure of the state of semiclosed or close closing, and manual or pneumatic socket drill cannot be to riveting
The counterbore at the countersunk head position of nail or screw hole implements front processing, it is therefore desirable to reverse machining counterbore, typically reversely cuts
The reverse drawing counterbit for cutting processing is made up of counterbit and knife bar, and counterbit and knife bar can be dismantled and combined, when using first knife bar from
Penetrate in hole at open face, then counterbit is inserted in knife bar at semiclosed face end, pin counterbit and start processing.In process,
For avoid it is overproof and improve machining accuracy, workman must in the careful trial cut of each working position, therefore, the installation of counterbit and knife bar
It is very crucial with matching.
Therefore, these problems for existing for prior art, research and development it is a kind of can Fast Installation cutter head and knife bar, and can be by
The firm counterbore being fixed on knife bar of cutter head, has great importance.
The content of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide a kind of can Fast Installation cutter head and knife
Bar, and the counterbore being fixed on knife bar that cutter head can be consolidated, for solving the problems of the prior art.
The technical scheme is that：
A kind of counterbore, including knife bar and cutter head, institute's knife bar include handle of a knife, shoulder, cutter head connecting rod, the handle of a knife,
Shoulder, cutter head connecting rod are formed integrally successively, and the cutter head connecting rod is provided with tool bit connecting structure, the tool bit connecting structure
For three planes being connected with each other, the first plane, the second plane, the 3rd plane are followed successively by, and angle is between adjacent plane
120 °, described first plane one end extends to the cutter head connecting rod end, and second plane, the 3rd plane are in the cutter head
Upwards two ends are limited pitman shaft by the cutter head pitman shaft, and the cutter head is cylinder, and is axially arranged with through hole, described
Through-hole side wall is provided with the vertical plane matched with first plane, the second plane, the 3rd plane, and the cutter head side is provided with knife
Piece, the blade is many pieces, and the blade is formed integrally with the cutter head.
Further, the blade is even number piece, and symmetrical on the cutter head.
Further, the blade is 2 pieces, and symmetrical on the cutter head.
Further, the blade is high-speed steel blade.
Further, the handle of a knife is provided with the connection plane being connected with drive mechanism.
The beneficial effects of the present invention is：
Cutter head can be inserted in knife bar by the present invention rapidly, and tool bit connecting structure can guarantee that and connect the stable cutter head that is fixed to of cutter head
On extension bar, the blade energy counterbit plane that cutter head is provided with, the equipment can rapidly process workpiece, improve workman's operating efficiency.
