Abstract

The utility model discloses a cutter used to process the outer thread of a work piece in a mechanical processing industry. the cutter is applied to a common lathe or a numerical control lathe to process the outer threads, particularly applicable to processing the outer threads of work pieces with chamfer angle on the end face, such as oil pipes, sleeve pipes, drill rods, etc., used in a petroleum processing industry. The cutter provided by the utility model comprises a cutter body and a cutter bit; the cutter bit is provided with a deburring blade and a thread cutter; the thread cutter blade is fixed on the top end of the cutter bit; the deburring blade is fixed on the left end of the cutter bit. The cutter provided by the utility model is used to process the outer thread of the work pieces with chamfer angle; the deburring blade is fixed on the left side of the thread cutter, so, thread processing and deburring does not be affected, but the rotation of a cutter carrier can be reduced by once, thereby shortening the processing time, improving the processing efficiency and reducing the equipment fault rate. Meanwhile, the two blades are integrated on the same tool, which reduces the material consumption of the tool and the tool cost.

Description

The externally threaded cutter of a kind of processing work
Technical field
The utility model belongs to the turning cutting tool of mechanical processing industry, the externally threaded cutter of particularly a kind of processing work, be used in threading on engine lathe or the numerically controlled lathe, be particularly useful for processing the external screw thread that end faces such as oil pipe that petroleum industry uses, sleeve pipe, drilling rod have the chamfering workpiece.
Background technology
At present, having the external screw thread of chamfering workpiece at engine lathe or lathe in machining end face, is to carry out according to traditional technology substantially, comprises end face, cylindrical, screw thread, four manufacturing procedures of burr.After finishing external screw thread processing, the rotor platform is removed burr with burring knife again, processes a product needed and rotates four cutter spacing.So both increased process time, the cost of charp tool is increased, and the increase of the fault rate of equipment cutter platform, maintenance is frequent, and working (machining) efficiency is not high, also increases maintenance cost.
Summary of the invention
The purpose of this utility model provides the externally threaded cutter of a kind of processing work, changes cutter structure, reduces the number of revolutions of lathe cutter platform, improves working (machining) efficiency.
For reaching above-mentioned purpose, can use the present technique solution: the externally threaded cutter of a kind of processing work comprises cutter hub and cutter head, and burring knife and screwer are set on cutter head, and screwer is fixed on the top of cutter head, and burring knife is fixed on the left end of cutter head.
Compared with prior art, the utlity model has following useful effect: use the utility model processing end face to have the external screw thread of chamfering workpiece, because burring knife is fixed on the left side of screwer, so neither influence screw thread processing, reduce again and rotate this operation of burring knife, reduce the rotating knife platform once.Shorten process time, improved working (machining) efficiency, also reduced breakdown rate.Because two cuttves have been incorporated on the cutter hub, reduce the spillage of material of cutter hub simultaneously, reduced the cost of charp tool.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, the externally threaded cutter of a kind of processing work comprises cutter hub 1 and cutter head 2, burring knife 4 and screwer 3 are set on cutter head 2, and screwer 3 is fixed on the top of cutter head 2, and burring knife 4 is fixed on the left end of cutter head 2.The α angle that the sword limit of burring knife 4 and cutter hub 1 axis form is arbitrarily angled between ° angle, 40 ° of angles to 70, as equal angles such as 45 °, 65 °, with the chamfering of suitable processing different angles.The sword limit of burring knife 4 equates with the height of screwer 3 blade tips, is in same plane.
During concrete the use,, adjust the welding fixed angle of burring knife 4, adapt to the processing request of workpiece end face chamfering according to the processing request of workpiece external screw thread and end face chamfering.The utility model is installed on the cutter platform, at first finishes externally threaded processing with screwer 3.Mobile again cutter platform is removed burrs and is finished the processing of workpiece end face chamfering with burring knife 4.

Claims (3)

1, the externally threaded cutter of a kind of processing work, comprise cutter hub (1) and cutter head (2), it is characterized in that burring knife (4) and screwer (3) are set on cutter head (2), screwer (3) is fixed on the top of cutter head (2), and burring knife (4) is fixed on the left end of cutter head (2).
