Abstract
The invention relates to a vehicle crankshaft journal angle rounding tool which comprises a tool body, round corner shaping blades and a tool bar arranged on a tool platform of a machine tool. A dovetail groove is arranged in the tool bar. Tool grooves are respectively arranged in four corners of the front end face of the tool body. Four round corner shaping blades are respectively arranged in the tool grooves and are tightly pressed and fixed through screws. A dovetail protrusion is arranged on the rear portion of the tool body. The tool body is matched with the dovetail groove of the tool bar through the dovetail protrusion and is inserted into the tool bar and is tightly pressed and fixed through a hold-down mechanism. In the working process, two round corner shaping blades on the upper portion are used for achieving turning to round corners of a crankshaft journal. When the two round corner shaping blades on the upper portion are worn, the tool body can be rotated at 180 degrees, the remaining two good round corner shaping blades can be used continuously, and production efficiency is improved. The vehicle crankshaft journal angle rounding tool is simple and reasonable in structure, convenient to operate and use, and high in tool replacing and assembling efficiency, and is an ideal tool for turning the round corners of the crankshaft journal.
Description
Technical field
The present invention relates to turning main bearing journal cutter, specifically a kind of car crankshaft journal fillet cutter.
Background technology
We know, being installed on engine crankshaft processes through multiple working procedure, wherein rough turn axle journal special plane turning commonly used, due to each axle journal two ends with fillet, with two fillet forming-tools during turning, be arranged on knife bar anterior dovetail both sides of protruding, the middle part of protrusion is with a screw in compression briquetting, and then compresses two fillet forming-tools.Two screws and cutter bottom surface location adjustment height are housed respectively on the cutter platform, make the tough centering crankshaft journal of fillet forming-tool longitudinal centre line, in order to process.In above-mentioned prior art, two fillet forming-tools are directly installed on knife bar, and knife bar is arranged on machine tool table.Owing to frequently changing the factors such as product and tool wear, need frequent tool changing.Tool changing is not only time-consuming, and incurs loss through delay and produce.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple and reasonable for structure, easy for operation, and four blades are housed, the car crankshaft journal fillet cutter that the tool changing efficiency of assembling is high.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of car crankshaft journal fillet cutter, it is characterized in that: it includes cutter hub, fillet shaping blade and is installed on knife bar on machine tool table, described knife bar is provided with dovetail groove, described cutter hub front end face is respectively equipped with a cutter groove on four angles, four fillet shaping blades are arranged on respectively in the cutter groove, fix by screw in compression, the cutter hub rear portion is provided with the swallow-tail form projection; Cutter hub coordinates with the knife bar dovetail groove by the swallow-tail form projection, inserts knife bar and is fixed by the hold-down mechanism on knife bar.
Described screw passes the counterbore that fillet shaping blade is provided with, and coordinates with the screw that cutter hub is provided with, and screw is screwed into cutter hub, is fixed fillet shaping blade.
Described cutter hub bottom also is provided with the cramp bar of an adjustment height, on the machine tool table that support bar is installed.Cutter hub contacts with the cramp bar upper surface, and cramp bar plays the aiding support location, makes cutter hub stably be in the operating position of car crankshaft journal fillet.
Four fillet shaping blades are installed on four angles of cutter hub front end face of the present invention, and four is symmetrical up and down fillet shaping blade.During work, start lathe bent axle is rotated, the knife bar that is arranged on machine tool table drives whole tool feeding, realizes turning to the crankshaft journal fillet by two fillet shaping blades on top.After two fillet forming-tool pad wears on top, cutter hub can be unloaded, rotate up and down 180 °, continue to use two remaining intact fillet shaping blades to carry out turnery.Like this, greatly improved production efficiency.Against existing technologies, the present invention is simple and reasonable for structure, and is easy for operation, and four blades are housed, and the tool changing efficiency of assembling is high, is a kind of desirable car crankshaft journal fillet cutter.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is that assembly structure master of the present invention looks schematic diagram.
Fig. 2 is that schematic diagram is looked on an assembly structure of the present invention left side.
Fig. 3 is assembly structure schematic top plan view of the present invention.
1. fillet shaping blades in figure, 2. screw, 3. cutter hub, 4. knife bar, 5. cramp bar, 6. bent axle.
The specific embodiment
Can find out from Fig. 1, Fig. 2 and Fig. 3, a kind of car crankshaft journal fillet cutter, it includes cutter hub 3, fillet shaping blade 1, knife bar 4, cramp bar 5 etc.Described knife bar 4 is installed on machine tool table, and knife bar 4 is provided with dovetail groove.Also be provided with the cutter hub mechanism that is fixed and clamped on knife bar 4.
Described cutter hub 3 front end face is respectively equipped with a cutter groove at an angle on four angles, and four are arranged on fillet shaping blade 1 respectively in the cutter groove, are fixed by screw 2.Specifically fillet shaping blade 1 is provided with counterbore, and cutter hub 3 upper knife groove inboards are provided with screw, and described screw 2 passes the counterbore on fillet shaping blade 1, coordinates with screw on cutter hub 3, and screw 2 is screwed into cutter hub 3, is fixed fillet shaping blade 1.
Described cutter hub 3 rear portions are provided with the swallow-tail form projection; Cutter hub 3 dovetail groove protruding by swallow-tail form and on knife bar 4 coordinates, and the insertion knife bar also is fixed by the hold-down mechanism on knife bar.The composition structure of this hold-down mechanism is identical with prior art, repeats no more.
Described cutter hub 3 bottoms also are provided with the cramp bar 5 of an adjustment height, on the machine tool table that support bar 5 is installed.Cutter hub 3 contacts with cramp bar 5 upper surfaces, and cramp bar 5 plays the aiding support location, makes cutter hub 3 stably be in the operating position of car crankshaft journal fillet.
Four fillet shaping blades are installed on four angles of cutter hub front end face of the present invention, and four is symmetrical up and down fillet shaping blade.During work, start lathe bent axle 6 is rotated, the knife bar that is arranged on machine tool table drives whole tool feeding, realizes turning to bent axle 6 axle journal fillets by two fillet shaping blades on top.After two fillet forming-tool pad wears on top, cutter hub can be unloaded, rotate up and down 180 °, continue to use two remaining intact fillet shaping blades to carry out turnery.Like this, greatly improved production efficiency.
The present invention is simple and reasonable for structure, and is easy for operation, and four blades are housed, and the tool changing efficiency of assembling is high, is a kind of desirable car crankshaft journal fillet cutter.
