Description

A kind of elastic cutter bar

Technical field

The utility model belongs to machine tool equipment technical field, and in particular to a kind of elastic cutter bar.

Background technology

Lathe tool is the cutter for turnery processing, with a cutting tip.Lathe tool is most widely used in machining One of cutter.The working portion of lathe tool is exactly generation and the part for handling chip, including blade, chip is broken broken or is wound up The structural elements such as space, the passage of cutting fluid of storage chip are held in structure, chip removal.At present, the lathe tool on existing lathe is mostly It is that alloy cutter head is welded direct to lathe tool side's knife bar, then direct clamping is to carrying out turnery processing on knife platform, this form Lathe tool is in turnery processing large modulus worm screw, and because the very big knife bar in penetration of a cutting tool face produces vibrations, cutting worm surface smoothness is coarse； Due to the vibrations of knife bar, blade is easy to forge a knife；In turning, due to excircle of workpiece bounce, the depth of turning be not it is very uniform, So being easy to knife, the quality of product is influenceed, low production efficiency adds production cost.

Utility model content

The utility model purpose is：A kind of elastic cutter bar is aimed to provide, cushioning effect can be played to blade in turning, Reduce the number of times forged a knife, prevent knife and spring knife, reduce sharpening number of times, improve the service life of blade, improve processing efficiency and Crudy, and can more allowing blade replacement, simple and fast at any time.

To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：

A kind of elastic cutter bar, including handle of a knife, the handle of a knife left end are connected with cutter head, and the preceding surface of cutter head is connected with pressure Plate, the pressing plate right-hand member is connected with studs, and the pressing plate is detachably connected by studs with cutter head, and the cutter head is left Front end is connected with blade and edge bearing, and the insert rear surface is fitted with the preceding surface of edge bearing, is connected with the middle part of the blade and edge bearing Alignment pin, the blade and edge bearing are detachably connected by alignment pin with cutter head, and handle of a knife set, the knife are arranged with outside the handle of a knife Cushion is provided with the inside of sleeve right side wall, the handle of a knife set left part opens up fluted, and the cross section of the groove is concave, institute State and flexure strip is filled with groove, the preceding surface right part of the handle of a knife set, which is offered in through hole, the through hole, is connected with screw, described Handle of a knife set is connected by screw with handle of a knife.

Using the utility model of the technical program, during installation, first by handle of a knife insertion handle of a knife set, make handle of a knife right-hand member and bullet Property pad contact, by screw by handle of a knife set be fixedly connected with handle of a knife, then handle of a knife set is put into knife platform, by handle of a knife cover it is upper Lower surface, which covers handle of a knife, to be fixed；During turning, when the power that blade is received is excessive, cross force can sequentially pass through blade and cutter head is passed to Handle of a knife, cushion plays cushioning effect to the right to handle of a knife, and longitudinal force can sequentially pass through blade, cutter head and handle of a knife and pass to handle of a knife Set, cushion plays downward cushioning effect to handle of a knife set, so as to reduce impact of the Cutting Force to blade；When long-time is used Afterwards, it is necessary to during more allowing blade replacement, need to only unload alignment pin, the blade more renewed, then alignment pin is loaded onto.Such structure Design, can play cushioning effect in turning to blade, reduce the number of times forged a knife, and prevent knife and spring knife, reduce sharpening time Number, improves the service life of blade, improves processing efficiency and crudy, and can more allowing blade replacement, simple and fast at any time.

Further limit, the quantity of the through hole and screw is two.Such structure design, connection is more consolidated, Good fixing effect.

Further limit, the screw is hexagon socket cap head screw.Such structure design, with being easy to fasten and tear open The advantages of unloading, be not easy to slide angle.

Further limit, the cushion is hard rubber pad.Such structure design, cost is low, good buffer effect.

Further limit, the thickness of the flexure strip is 1mm.Such structure design, with more preferable buffering effect Really.
