Abstract

The utility model relates to a mechanically clamped turning tool for a ring groove of a stepped end face, and in particular relates to the mechanically clamped turning tool which is used for turning the ring grooves in the stepped end faces of various pore plate joints of parts in the coal chemical industry. The turning tool comprises a tool bit and a tool body which are configured to be a split structure; the tool bit comprises a front tool surface, a bottom surface, a tool bit internal arc surface and a tool bit external arc surface which are all machined in a linear cutting manner; the tool body comprises a tool body internal arc surface and a tool body fit surface which are both machined in a liner cutting manner; the tool bit external arc surface and the tool body internal arc surface are matched; the tool body fit surface and the tool bit bottom surface are matched with each other and are mechanically clamped and fixed by a pressing block and a compression screw. According to the mechanically clamped turning tool for the ring groove of the stepped end face provided by the utility model, as the height of the tool bit is additionally arranged along the direction of a machined workpiece ring groove and the strength of a blade is improved by assembling the turning tool in the mechanical clamp manner, the tool is prevented from breaking when turning the groove.

Description

A kind of step end face annular groove mechanically-clamped turning tool
Technical field
The utility model relates to a kind of mechanically-clamped turning tool, relates in particular to a kind of suitable coals chemical industry part various " orifice plate joint " step end face annular groove turning processing mechanically-clamped turning tool.
Background technology
Coal Chemical Industry gasification furnace membrane wall aquaporin uses the orifice plate joint of a large amount of structural similarities, wherein on a kind of orifice plate joint step end face a cannelure is arranged, breaking was serious when lathe carried out grooving, use common brazed carbide turning tool, did multiple effort, problem can't solve always, has had a strong impact on the manufacturing schedule of product.Because the workpiece end face annular groove space of some orifice plate joints is very little, for knife face after avoiding lathe tool is interfered with finished surface of the work, must increasing lathe tool relief angle, cause that the cutter head height is too small, intensity is too poor, thus breaking when causing grooving.Through design of part is thought: breaking when the raising edge strength can reduce grooving dramatically may be to increase the cutter head height and improve the unique of edge strength.For avoiding relief angle and finished ring groove surface to interfere, the cutter head height must increase along the annular groove circumferencial direction.But when adopting brazed shank tool, the cutter head internal and external cambered surface is difficult to grind by hand.
The utility model content
The utility model is at above-mentioned the deficiencies in the prior art, and a kind of various orifice plate joint of suitable coals chemical industry part step end face annular groove turning processing mechanically-clamped turning tool of the raising edge strength of breaking when avoiding recessing occurring is provided.
The technical solution of the utility model is achieved in that a kind of step end face annular groove mechanically-clamped turning tool, comprises cutter head and cutter hub, and described cutter head and cutter hub are for dividing body structure; Described cutter head comprises rake face, bottom surface, cutter head intrados and the cutter head extrados of all processing by the line cutting mode, and described cutter hub comprises cutter hub intrados and the cutter hub binding face of all processing by the line cutting mode; Described cutter head extrados cooperates with described cutter hub intrados, and described cutter hub binding face cooperates with head base surface, and fixed by compact heap and housing screw machine clamping.
Described cutter head is sickle shaped.
The width of described cutter head narrows down to its bottom surface gradually from its rake face.
The peak of described compact heap can not be higher than the minimum point on the described cutter head intrados.
Described cutter head also comprises the cutter head arc surface that grinds by manual.
The good effect that the technical solution of the utility model produces is as follows: cutter head and cutter hub adopt and divide body structure, and the fixing lathe tool of the mode by machine folder, the cutter head height increases along the annular groove circumferencial direction, avoided the interference of relief angle and ring groove surface, and then improved edge strength, breaking when having reduced recessing has been accelerated manufacturing schedule.Wherein, the width of described cutter head narrows down gradually from its rake face to its bottom surface and interferes the cutter head and workpiece in the time of can effectively avoiding cutting.

Be labeled as among the figure: 1, cutter head; 2, cutter hub; A-1, cutter head intrados; A-2, cutter head extrados; A-3, rake face; A-4, bottom surface; A-5, cutter head arc surface; B-1, cutter hub intrados; B-2, cutter hub binding face; 3, compact heap; 4, housing screw.
The specific embodiment
Below in conjunction with description of drawings and specific embodiment the utility model is further described.
Shown in Fig. 1,2,3,4, a kind of step end face annular groove mechanically-clamped turning tool comprises cutter head 1 and cutter hub 2, and described cutter head and cutter hub are for dividing body structure.Described cutter head is sickle shaped, cutter head comprises cutter head intrados A-1, cutter head extrados A-2, rake face A-3, bottom surface A-4 and cutter head arc surface A-5, wherein cutter head intrados, cutter head extrados, rake face and bottom surface all process by the line cutting mode, the cutter head arc surface grinds by manual, and measures by the sharpening sample; Cutter head and workpiece to be machined arc surface interfere when avoiding cutting, the cutter head width from rake face on earth face narrow down gradually.Described cutter hub comprises cutter hub intrados B-1 and cutter hub binding face B-2, and cutter hub intrados and cutter hub binding face all process by the line cutting mode.Described cutter head and cutter hub are fixed by compact heap 3 and housing screw 4, and wherein the cutter head extrados matches with the cutter hub intrados, and head base surface cooperates with the cutter hub binding face, and each face of cutter head and cutter hub that guarantees is fitted reliable; Compact heap and workpiece to be machined interfere when avoiding cutting, and the peak of compact heap can not be higher than the minimum point on the described cutter head intrados.
The width of described rake face is identical with workpiece to be machined end face ring well width, and the length of described cutter head determines according to workpiece ring groove depth, cutter hub width and wearing and tearing allowance, cause the blade wearing and tearing in the use after, can carry out repeatedly sharpening.According to the difference of workpiece to be machined material, tool tip material can adopt high-speed steel or carbide alloy, No. 45 steel modifier treatment of cutter hub material selection.
Described cutter head and cutter hub are for dividing body structure, and cutter head and cutter hub clamping cutter head position all process by the line cutting mode, with machine folder mode that cutter head and cutter hub is fastening again, be combined into mechanically-clamped turning tool, the cutter head height increases along the annular groove direction of cutting workpiece, avoid interfering and take place, and improved edge strength by increasing the cutter head height, avoided when turning, occurring the situation of breaking, enhance production progress, reduce production costs, improved production efficiency.
