Therefore avoid knife bar vibrations to be of practical significance very much when turning deep hole, design prevents the knife bar of vibrations from having very important meaning.
Summary of the invention
The purpose of this utility model is: for above-mentioned the deficiencies in the prior art, it is provided that the deep hole turning vibration damping knife bar of a kind of damping.
The technical solution adopted in the utility model is, a kind of deep hole turning vibration damping knife bar, including cutter bar body, this cutter bar body one end is connected with lathe, the cutter bar body other end is connected with cutter head, this bit tip is provided with the cutter groove installing turning cutting tool, and described cutter head is radially provided with a bearing, and the distance at the top of this bearing to cutter head center is matched with the internal bore radius value of workpiece turning.
Described cutter bar body is threadeded with cutter head.
Further, being provided with stepped hole inside described cutter bar body, this stepped hole diameter increases the most successively.
Described cutter bar body is provided with positioning boss, is connected by the installing hole correspondence on positioning boss is fixing with lathe tool rest.
Described cutter head is provided with cutter trip bolt, and this cutter trip bolt is radially arranged on cutter head, the bottom of cutter trip bolt extends in cutter groove.
Described bearing is arranged on middle part or the rear portion of cutter head by the installing hole on cutter head.
The beneficial effects of the utility model are:
1. this utility model solves deep hole turning workpiece very well, by the long vibrations brought of knife bar, improves working (machining) efficiency and machining accuracy
2. the setting of stepped hole in this utility model knife bar, alleviates the weight of whole knife bar.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Code name implication in figure: 1 cutter bar body；2 cutter heads；3 bearings；4 stepped holes；5 positioning boss；6,9 installing hole；7 cutter grooves；8 cutter trip bolts.
Detailed description of the invention
Shown in Figure 1: this utility model is a kind of deep hole turning vibration damping knife bar, including cutter bar body 1.
Above-mentioned cutter bar body one end is connected with lathe, it connects end is fixed part, the cutter bar body other end is provided with the cutter head 2 installing turning cutting tool, installing hole 9 radially it is provided with on described cutter head 2 sidewall, being fixed with the bearing 3 matched with installing hole 9, this bearing 3 is positioned at middle part or the rear portion of cutter head 2.The internal bore radius value with workpiece turning is mated to the distance between cutter head 2 center in bearing 3 top stretching out installing hole 9 part.Wherein, 2 side from fixed part side to cutter head, stepped hole 4 it is provided with inside described cutter bar body, the diameter of this stepped hole 4 is by being gradually increased (i.e. to 4 mouthfuls of directions of stepped hole in cutter bar body 1, fixed part side is minor diameter one end of stepped hole 4, cutter head 2 side is major diameter one end of stepped hole 4, stepped hole 4 aperture of this major diameter one end offers female thread, the external screw thread arranged with cutter head 2 external rear face is threadeded), to reach to alleviate the purpose of knife bar vibrations, alleviate the weight of whole knife bar simultaneously；Installing hole 9 on described cutter head 2 is shoulder hole, the epimere small diameter bore section of this shoulder hole is provided with the corresponding female thread matched with external screw thread on a bearing 3 epimere cylinder, the large diameter hole section (counterbore section) of this shoulder hole is corresponding mates with a bearing 3 hypomere cylinder boss, the bottom of this cylinder boss becomes arc surface, it is so designed that, further enhance the location supporting role of cutter bar body 1, cutter head 2, prevent cutter bar body 1 and the big-eared head of cutter head 2 and vibrations, it is ensured that smooth, qualified processes deep hole；Described bearing 3 uses high-abrasive material to make, and increases its anti-wear performance, improves working (machining) efficiency and machining accuracy.
Fixation portions is to be arranged at the positioning boss 5 of cutter bar body 1 outer surface, and this stepped hole 4 is between positioning boss 5 and cutter head 2.This positioning boss 5 is partial to lathe and is connected the optical axis that cutter bar body 1 is smooth outer surface at place, side, and positioning boss 5 is provided with the corresponding installing hole 6 being connected with lathe, has three installing holes 6 in the present embodiment on positioning boss 5.It is connected by the installing hole 6 on positioning boss 5 and the tool rest on lathe are fixing.
The rear external thread correspondence of above-mentioned cutter head 2 realizes threadeding with the female thread of cutter bar body 1, and the external screw thread correspondence on the rear portion of cutter head 2 spins with cutter head 2 side, cutter bar body 1 place, the female thread in aperture, stepped hole 4 major diameter one end；The front end face of this cutter head 2 is provided with the cutter groove 7 installing turning cutting tool, and cutter groove 7 is provided with the cutter threaded fastener of corresponding fastening turning cutting tool, this utility model is cutter trip bolt 8, this cutter trip bolt 8 is radially arranged on cutter head, the bottom of cutter trip bolt 8 extends in cutter groove 7, for fixing the turning cutting tool in cutter groove, this cutter trip bolt 8 is set as plane with the contact surface of cutter head 2 outer surface, to improve location and the effect of fastening.
Installation process: during processing inner hole of workpiece, lathe drives workpiece to rotate, turning cutting tool carries out turner endoporus along the endoporus direction of turner, during feeding, bearing 3 machined the endoporus hole wall of certain depth and contact, fits with workpiece, then moves with the direction of feed of the continuous past endoporus turning of cutter bar body 1；Bottom cutter head 2, external screw thread screws fixing with cutter bar body 1 stepped hole 4 enlarged diameter section inwall female thread；The fixed part of cutter bar body 1 inserts lathe tool rest endoporus, the installing hole 6 that the installing hole 6 on the positioning boss 5 at fixed part is corresponding with on lathe end surface of knife holder is made to align by swivel knife carrier body 1, the securing members such as screw are used to fix, ensure that a bearing 3 screws in the screwed hole arranged on cutter head 2 sidewall from bottom to top, make a top, circular arc center, bearing 3 bottom surface consistent with the inner hole of workpiece radius needing processing to the distance coupling at cutter head 2 center；In turning cutting tool embeds the cutter groove 7 of top setting of cutter head 2, adjust the cutting-tool angle of turning cutting tool, cutter trip bolt 8 is screwed in fixing cutter head 2 place cutter groove 7, arrive the fixing of turning cutting tool；To cutter, starting lathe, drive workpiece to rotate, knife rest phase inner hole of workpiece depth direction moves, it is achieved steadily turnery processing.
