The utility model is a kind of machining cutting tool, especially a kind of machining tool that is used for the turning Internal Spherical Surface.
At present, the domestic cutting tool that are usually used in the turning Internal Spherical Surface are more, advanced few in the design, as working out by Shanghai City metal cutting technology association, " disclosed link-type Internal Spherical Surface cutting tool and the towed Internal Spherical Surface cutting tool in the metal cutting handbook published by Shanghai science tech publishing house in April, 1984, though they have solved the problem of turning Internal Spherical Surface to a certain extent, but also exist a lot of defectives, wherein link-type Internal Spherical Surface cutting tool generally can only be applied on the C6160 type lathe, narrow application range, simultaneously when regulating cutting depth, must be equidirectional, while is movable tail frame axle and saddle equidistantly, adjusts inconvenient and is difficult for the person of being operated and grasp, in addition, it only is applicable to that the processing radius is 100～1300 millimeters a Internal Spherical Surface, and roughness is big; The manufacturing of towed Internal Spherical Surface cutting tool, installation inconvenience, there is sliding phenomenon during simultaneously owing to rope traction rotating knife axon, thereby velocity of rotation that can not strict control lathe tool, the Internal Spherical Surface roughness that processes increases inevitably, in sum, all there is the defective in the design in above-mentioned two kinds of cutting tool, can't turning accuracy height and the little Internal Spherical Surface of radius.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of applied widely, manufacturing, installation, easy to use is provided, interchangeability is strong, the Internal Spherical Surface of the above radius of energy turning 20mm, and can make it reach the Internal Spherical Surface cutting tool of standard of tolerance IT7 level.
The purpose of this utility model is achieved in that
Gear type Internal Spherical Surface cutting tool remove by cutter hub, there is the knife bar of through hole the centre, the Internal Spherical Surface lathe tool, outside the runner of band handle is formed, also increased teeth bar lead screw, gear, axle sleeve, Connection Block, tool rest, parts such as dust cap and fastening bolt, knife bar is fixed on the cutter hub by fastening bolt, Connection Block also is fixed in the rear end face of cutter hub by fastening bolt, fastening bolt embeds in the groove on the runner and runner is fixed among the Connection Block, runner can only can not moved axially radially rotating, the screw thread pin thread of teeth bar lead screw one end and the screw thread box in the runner are complementary, teeth bar lead screw and runner screw, and can be just with runner, reverse rotation and axially moving around, tooth on the rack and pinion on the teeth bar lead screw is complementary and interlock mutually, gear can moving axially and rotate with teeth bar lead screw, gear is by a pair of axle sleeve engaging of being fixed in the knife bar hole, two axle sleeves engage respectively by junction of the edges of two sheets of paper screw and are fixed in the hole of knife bar, the Internal Spherical Surface lathe tool is fixed on the tool rest by fastening bolt, tool rest is fixed on the axle of gear by key, the Internal Spherical Surface lathe tool can be rotated with the rotation of gear, and the size in the hole on the size of dust cap and the knife bar is complementary and engages thereon.
Wherein, this reality is novel has also increased by fastening bolt fixing rough turn endoporus or grooving cutter at the head of knife bar.
In addition, the utility model provides the Internal Spherical Surface cutting tool of a series of different models, can select knife bar, tool rest, Internal Spherical Surface lathe tool, rough turn endoporus or grooving cutter, gear, axle sleeve and the dust cap of different model according to the Internal Spherical Surface of processing different inner diameters, to adapt to processing request.
Because the utility model has reasonably been taked teeth bar lead screw and the gear major part as transmission device, so manufacturing, installation and use are quite convenient, and can be applicable to the lathe of multiple model, as: C616, C6140, C6160 etc., when the processing Internal Spherical Surface, it is contour to adjust cutting edge and point of a knife height and lathe spindle pivot, the pivot of lathe tool can be adjusted to the design centre of workpiece simultaneously to overlap, so can increase the precision of the Internal Spherical Surface of being processed effectively; In addition, the utility model has also designed rough turn endoporus or grooving cutter, utilizes its at first thick endoporus of car or grooving, uses Internal Spherical Surface lathe tool car sphere again, has saved man-hour, has improved operating efficiency and has increased service life of Internal Spherical Surface lathe tool; Moreover, the utility model has also designed a series of knife bars, tool rest, Internal Spherical Surface lathe tool, rough turn endoporus or grooving cutter, gear, axle sleeve and dust cap, can select according to the size of turning Internal Spherical Surface diameter, interchangeability of the present utility model is strengthened, scope of application augmentation, can process radius is the above Internal Spherical Surface of 20mm, but utilizes the utility model machining tolerance grade to be IT7, and surface roughness is
Form tolerance is
Internal Spherical Surface.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a main pseudosection of the present utility model;
Fig. 2 is a vertical view of the present utility model.
(1) bulb diameter S Φ 40 in the processing
-0.012 + 0.018The endosphere face;
(2) bulb diameter S Φ 80 in the processing
-0.012 + 0.018The endosphere face.
Use lathe C6140, workpiece material HT200, lathe tool material are carbide alloy YG6, and knife bar, cutter hub, tool rest and miscellaneous part are 45 steel, adopt gear type Internal Spherical Surface cutting tool to process, and the cutter overall package is as follows:
Knife bar 3 is contained in the hole of cutter hub 2, with fastening bolt 11,12 fuse knife bar 3 and cutter hub 2, Connection Block 1 is by fastening bolt 14,17 are fixed in the rear end face of cutter hub, in the groove 23 that fastening bolt 13 embeds on the runner 16 runner 16 is fixed in the Connection Block 1, teeth bar lead screw 6 is loaded in the through hole of knife bar 3, be connected with screw thread box revolving type in the runner 16 by the screw thread pin thread of one end, the mutual interlock of tooth on the rack and pinion 9 on the teeth bar lead screw 6, gear 9 is fastened in the hole of knife bar 3 by axle sleeve 4 and 7, axle sleeve 4 is fastened in the hole of knife bar 3, axle sleeve 7 is fixed in the hole of knife bar 3 by junction of the edges of two sheets of paper screw 22, Internal Spherical Surface lathe tool 18 is fixed on the tool rest 5 by fastening bolt 21, tool rest 5 is fixed on the axle of gear 9 by key 10, the size in the hole on the size of dust cap 8 and the knife bar 3 is complementary, dust cap 8 is fastened on the hole on the knife bar 3, is fixed with rough turn Boring cutter 19 at the head of knife bar 3 with fastening bolt 20.
