Abstract
The utility model provides a drop-preventing gear cutter hob with retainer ring and inlaid chip, comprising a cutter body, a retainer ring installed on the two ends of the cutter body. The brace table at the both ends of the cutter body has a 1. 0-1. 5 degree inner cone; the inner wall of the retainer ring is provided with a taper which cooperates with the inner cone on the brace table. After the cutter body of the utility model is assembled with the retainer ring; the back taper of the retainer ring is fixed on the brace table; the taper surface of the brace table and the retainer ring are formed to a self-locking system, which make the retainer ring is fixed on the brace table. The retainer ring can not be taken down with the non-destruction retainer ring, and can not drop with multiple knocking; also can guarantee the accuracy of the cutter, can extend the service life.
Description
(1) technical field
The utility model relates to a kind of machine tools.
(2) background technology
Empiecement hobboing cutter cutter hub support end platform in the past is a cylindrical structural, and the phenomenon that in use often has retainer plate to come off takes place, and causes the blade loose or dislocation, gear hob can not normally be used, even scrap.Cause the main cause of this phenomenon to be: tipped gear hob is the gear cutting tool of processing modulus more than 9, and tool weight is big, and endoporus precision height is not easy to install.Cutter hub brace table and retainer plate contact-making surface are two to be faced directly, manually in when loading and unloading, knocks retainer plate with weight and finishes loading and unloading, repeatedly knocks retainer plate is come off etc.
(3) summary of the invention
The purpose of this utility model is to provide a kind of can prevent the blade loose or dislocation effectively, simple in structure, does not increase the slip-off preventing retainer plate tipped gear hob of production cost.
The purpose of this utility model is achieved in that it comprises that cutter hub is installed in the retainer plate at cutter hub two ends, and the brace table at cutter hub two ends has 1.0-1.5 ° inner cone, and the tapering that matches with inner cone on the brace table is arranged on the inwall of retainer plate.
After cutter hub of the present utility model and the retainer plate assembling, the retainer plate back taper is fixed on supporting platform, the tapering face of brace table and the tapering face of retainer plate form self-locking, make retainer plate being fixed on the brace table tightly, under the situation of not destroying retainer plate, retainer plate can't be taken off, can not come off because of repeatedly knocking.Structure of the present utility model can solve the problem of empiecement hobboing cutter blade loose or dislocation effectively, can guarantee the precision of cutter, increases the service life.
Structure of the present utility model can adopt such method to process: when mill tipped gear hob brace table, lathe is removed 1.0-1.5 ° recessed angle.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of background technology.
(5) specific embodiments
Practical for a more detailed description to this for example below in conjunction with accompanying drawing:
In conjunction with Fig. 1, composition of the present utility model comprises cutter hub 1, is installed in the retainer plate 2 at cutter hub two ends, and the brace table at cutter hub two ends has 1.0-1.5 ° inner cone, and the tapering that matches with inner cone on the brace table is arranged on the inwall of retainer plate.The best tapering of the inner cone on the brace table at cutter hub two ends is 1.5 °.
Claims (2)
1, a kind of slip-off preventing retainer plate tipped gear hob, it comprises cutter hub, is installed in the retainer plate at cutter hub two ends, it is characterized in that: the brace table at cutter hub two ends has 1.0-1.5 ° inner cone, and the tapering that matches with inner cone on the brace table is arranged on the inwall of retainer plate.
2, slip-off preventing retainer plate tipped gear hob according to claim 1, it is characterized in that: the inner cone on the brace table at described cutter hub two ends is 1.5 °.
