The special shock absorber for the inner hole lathe tool comprises a tool bar and a shock absorber, wherein a tool shank in the shape of a cuboid is arranged on the right side of the too bar, a section of cylinder is arranged on the left side of the tool bar, a square tool arranging hole is arranged at the left end of the cylinder for placing a tool bit, and a tool pressing screw is arranged above the tool arranging hole for compressing the tool bit; and a shock absorber main body is in the shape of the cylinder, a round hole which is vertical to the main body is arranged at the upper part of the shock absorber main body, the shock absorber is sheathed on the cylinder on the left side of the tool bar through the round hole, a fastening screw is arranged at the upper end of the shock absorber main body, the lower part of the shock absorber main body is cylindrical, a vibrator made of steel is arranged in the shock absorber main body, an upper damping spring is arranged on the upper side of the vibrator, a lower damping spring is arranged on the lower side of the vibrator, a gland bush is connected at the bottom of the shock absorber in a rotating manner, and the vibration of the tool bar can be reduced by rotating the gland bush so as to achieve the purpose of shock absorption.
Description
Technical field
The utility model relates to the metal cutting aid, particularly a kind of special-purpose damper of internal lathe-tool that is used for reducing the cutter vibrations on the internal lathe-tool knife bar that is fixed on.
Background technology
In Vehicle Processing; Particularly when the Vehicle Processing deep hole; Because the knife bar of internal lathe-tool is longer, very easily produces the knife bar seismism, touches knife bar with hand this moment and can feel tangible vibrations; Examining the cutter head position sees to see something of the metal fine particle at bob; Can see that under the situation of using cooling fluid the vibrations of knife bar at this moment also can pass to processed workpiece and make the two resonance because the knife bar vibrations have some tiny globules at bob at the cutter head position, people also can hear the noise that pipes of vibrations.Because the resonance of knife bar and workpiece makes the roughness of the surface of the work that Vehicle Processing goes out reduce greatly, also aggravated the wearing and tearing of cutter simultaneously, can see that through visual observations surface of the work has the ripple of many arrangement regulations.These ripples have at first reduced the surface quality of surface of the work, also greatly reduce the service life of workpiece simultaneously.
Summary of the invention
The purpose of the utility model is to remedy the defective and the deficiency of prior art, provides a kind of internal lathe-tool special-purpose damper, and it can effectively overcome the problem that when the Vehicle Processing deep hole, occurs vibrations in the prior art easily.
Be to realize above-mentioned purpose, the technical scheme that the utility model adopts is following: the special-purpose damper of a kind of internal lathe-tool comprises the knife bar and the damper of internal lathe-tool; Wherein knife bar is processed through modifier treatment by medium carbon steel, its HRC38～42, and knife bar the right is one and is rectangular-shaped handle of a knife; The left side of knife bar is one section cylinder, and cylindrical left end has a square dress tool bore, is used to place cutter head; Above the dress tool bore, a push type broach screw is arranged, be used to compress cutter head; Absorber main body is a cylindrical shape, and a circular hole vertical with this main body is arranged at its top, is used for damper is enclosed within the cylinder on the knife bar left side through this circular hole; For fixing damper, be connected with a trip bolt in the absorber main body upper end, the absorber main body bottom is tubular; The oscillator that inside has steel to process; In the top of oscillator damping spring on is arranged, in the bottom of oscillator a following damping spring is arranged, the damper bottom is connected with a gland.
The method for using of the utility model is: the circular hole through absorber main body top is enclosed within damper on the cylinder on the knife bar left side; Damper is vertically placed; Gland is positioned at the below of damper; Damper 180 degree that also can overturn make gland be positioned at the top of damper, and the direction of the cutting force that produces when making metal cutting is consistent with the direction that damper is placed, and tightens trip bolt.Start lathe examination cutter; According to material and the machining dosage of selection and the concrete condition of cutter of part to be processed, penetration of a cutting tool limit, limit slowly rotates gland, thus the vibration frequency of adjustment knife bar self; Till vibrations hour, can come processing parts according to this concrete operating mode then.
The utility model compared with prior art beneficial effect is: the situation that vibrations take place in the time of can effectively overcoming the Vehicle Processing deep hole easily; Can improve the quality of products greatly and efficiency, when batch machining, once regulate damper; Promptly can process in batch; Can reduce requirement, can improve yield rate greatly, alleviate working strength of workers operator's technical merit.
