Abstract
The utility model relates to the field of mechanical machining, in particular to a reamer with a PCD composite blade easy to replace. The reamer with the PCD composite blade easy to replace comprises a base body and a knife handle with one threaded end. The base body is a cylindrical body and a certain number of fan blades are arranged in the cylindrical body. The fan blades are connected with a shaft in the middle. Threaded holes are formed in the shaft. The knife handle is connected with one end of the base body in a threaded mode. A certain number of blade bases are evenly distributed on the other end of the base body along the wall of the cylindrical body and are approximate to right trapezoids. PCD blades are fixedly connected on sides of end faces, vertical to the base body, of the blade bases. The PCD blades are used for being welded on a blade machine base. Implementation is simple, operation is convenient and new PCD blades can be welded on the blade bases by means of simple grinding. Little waste is produced and resources are saved. The fan blades are arranged in the middle of the cylindrical base body and can blow scraps when a drill drills holes out, make the scraps discharge more rapidly and improve machining quality. The base body is of a cylindrical structure so as to reduce weight of the base body and save materials. The base body and the knife handle are connected in a threaded mode, convenient to replace and capable of improving working efficiency.
Description
Technical field
The utility model relates to field of machining, is specifically related to a kind of reamer of easy replacing PCD composite blade.
Background technology
Now in the hole drill that uses, great majority adopt the electrogilding emery to form, every kind of drill bit can only adopt a kind of diamond dust of granularity, after drill bit uses and scraps, the matrix of drill bit does not damage, and can also use, so need reconditioning strip diamond dust, electrogilding emery again behind the reconditioning matrix makes the matrix of drill bit repeatedly to reuse; Reconditioning strip diamond dust, operation and trouble, and plating itself, waste diamond dust also can produce a lot of discarded electroplate liquids, contaminated environment.
Summary of the invention
The utility model proposes a kind of reamer of easy replacing PCD composite blade at the problem that prior art exists the recycling bit matrix to exist.
The technical solution of the utility model is: a kind of reamer of easy replacing PCD composite blade, comprise that matrix and an end are provided with the handle of a knife of screw thread, matrix is cylindrical body, be provided with the flabellum of some in the inside of cylindrical body, the axle at flabellum and middle part is connected, be provided with screwed hole at axle, one end of handle of a knife and matrix is by being threaded, at the other end of matrix along the even blade pedestal of distribution some on the barrel wall, the blade pedestal is that an approximate right angle is trapezoidal, is connected with the PCD blade on the limit of the vertical matrix end face of blade pedestal.
The reamer of described easy replacing PCD composite blade, it is characterized in that: the quantity of described flabellum is the 2-4 sheet, flabellum becomes 30 °～40 ° angle with plane, place, matrix end.
The reamer of described easy replacing PCD composite blade is characterized in that: the quantity of described blade pedestal is 2-6.
The beneficial effects of the utility model are: 1. drill bit of the present utility model adopts the PCD blade to be welded on this structure on the blade support, implement simple, easy to operate, only need simple polishing pedestal during repeated use, just can be at the new PCD blade of blade pedestal welding, produce very little discarded object, economize on resources.
2. be provided with flabellum at the middle part of matrix cylindrical body, in drill bit work, can the chip of boring generation be blown out, accelerate chip removal, improve processing quality, can also reduce the blade temperature simultaneously; Matrix adopting cylindrical body structure has reduced the weight of matrix, economical with materials; Matrix and handle of a knife adopt and are threaded, and are convenient for changing, and increase work efficiency.
Description of drawings
Fig. 1 is side perspective structural representation of the present utility model;
Fig. 2 is Facad structure schematic diagram of the present utility model;
