Abstract
The utility model discloses a grinding rod with a cemented carbide conducting bar inlaid in a rod body. The grinding rod with the cemented carbide conducting bar inlaid in the rod body comprises a honing stick, a rod body and a cemented carbide conducting bar and is characterized in that a dovetail groove is arranged in the rod body. The cemented carbide conducting bar is connected with the rod body in a mode of forked tail. The length of the cemented carbide conducting bar is equal to the length from a guide part of the rod body to the back end of the honing stick. The cemented carbide conducting bar is arranged within the working length of the rod body guide part and the honing stick. The cemented carbide conducting bar and the rod body are arranged in a structure of forked tail. Compared with the existing grinding rod, hardness and rigidity of the guide part of the grinding rod with the cemented carbide conducting bar inlaid in the rod body are improved, and therefore heat generation, swelling and bonding are not easy to occur. Then the quality of the processed holes is guaranteed, the accident of blocking of the rod and breaking of the rod is avoided, and therefore the fastness and reliability of the cemented carbide conducting bar arranged on the rod body is guaranteed and the cemented carbide conducting bar is not easy to fall in the operation.
Description
Technical field
The top gem of a girdle-pendant reamer of the utility model cutter hub carbide inserts sliver is a kind of process tool.
Background technology
Top gem of a girdle-pendant reamer is machined precision cutting tool commonly used.Present top gem of a girdle-pendant reamer is comprised of cutter hub and abrasive stick, and cutter hub is alloy tool steel, and surface hardening is processed (seeing accompanying drawing 3).The top gem of a girdle-pendant hinge of some special holes requires top gem of a girdle-pendant reamer body and workpiece bottom outlet interference fits, cutter hub and workpiece rotating mill sassafras during fraising.
Be directed to now the following shortcoming of the top gem of a girdle-pendant reamer existence of steel alloy:
Because cutter hub excessively cooperates with the workpiece bottom outlet, guiding and friction of workpiece in the cutter rotation process are because cutter hub is alloy tool steel, heat treatment hardness is limited, easily produce heating, swell, bonding, thereby exert an influence the machining hole quality, What is more causes that cutter is stuck, the accident of forging a knife.
The utility model content
The purpose of this utility model provides a kind of top gem of a girdle-pendant reamer of cutter hub carbide inserts sliver, and it mainly is made of abrasive stick, cutter hub and carbide alloy sliver, has dovetail groove on the cutter hub, and the carbide alloy sliver adopts the dovetail mode to be connected with cutter hub.The length of carbide alloy sliver equals from the targeting part of cutter hub until the length of abrasive stick rear end, guiding hardness and rigidity have been improved, be not easy to produce heating, swell, bonding, thereby guaranteed the machining hole quality, avoid that cutter is stuck, the accident of forging a knife, guaranteed that the carbide alloy sliver is solid and reliable on cutter hub, work is not easy to drop.
Technical solution of the present utility model is such, a kind of top gem of a girdle-pendant reamer of cutter hub carbide inserts sliver, it is characterized in that top gem of a girdle-pendant reamer mainly is made of abrasive stick, cutter hub and carbide alloy sliver, have dovetail groove on the cutter hub, the carbide alloy sliver adopts the dovetail mode to be connected with cutter hub.
The length of carbide alloy sliver equals from the targeting part of cutter hub until the length of abrasive stick rear end.
The utility model has the advantages that the carbide alloy sliver is connected employing dovetail structure with cutter hub, guaranteed that the carbide alloy sliver is solid and reliable on cutter hub, work is not easy to drop.
Description of drawings
It is such that structure of the present utility model consists of:
Fig. 1 is the front view of the top gem of a girdle-pendant reamer of cutter hub carbide inserts sliver.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the partial sectional view of Fig. 2.
Fig. 4 is the front view of the top gem of a girdle-pendant reamer of current use.
Fig. 5 is the cutaway view of the top gem of a girdle-pendant reamer of current use.
Among Fig. 1～Fig. 5, abrasive stick (1), cutter hub (2), carbide alloy sliver (3).
The specific embodiment
Most preferred embodiment of the present utility model is such.With reference to accompanying drawing, the top gem of a girdle-pendant reamer of cutter hub carbide inserts sliver, it comprises abrasive stick, cutter hub, the carbide alloy sliver, cutter hub has dovetail groove on (2), and carbide alloy sliver (3) adopts the dovetail mode to be connected with cutter hub (2).The length of carbide alloy sliver (3) equals from the targeting part of cutter hub (2) until the length of abrasive stick 1 rear end.The alloy sliver adopts the dovetail mode to be connected with cutter hub, and solid welding, and is solid and reliable.Because Cemented Carbide Hardness is higher, improved the cutter hub rigidity, be not easy to produce heating, swell, bonding, thereby guaranteed the machining hole quality, avoid that cutter is stuck, the accident of forging a knife.
The above namely is structure and the operation principle of the top gem of a girdle-pendant reamer of cutter hub carbide inserts.
Key point of the present utility model is that it compares with old top gem of a girdle-pendant reamer: 1) it has inlayed the carbide alloy sliver in cutter hub guiding and abrasive stick active length; 2) carbide alloy sliver and cutter hub adopt the dovetail structure.
Key point of the present utility model is that it compares with old top gem of a girdle-pendant reamer, it has inlayed the carbide alloy sliver in cutter hub guiding and abrasive stick active length, improved guiding hardness and rigidity, is not easy to produce heating, swell, bonding, thereby guaranteed the machining hole quality, avoided that cutter is stuck, the accident of forging a knife.
Claims (2)
1. the top gem of a girdle-pendant reamer of a cutter hub carbide inserts sliver, it is characterized in that top gem of a girdle-pendant reamer mainly is made of abrasive stick (1), cutter hub (2) and carbide alloy sliver (3), cutter hub has dovetail groove on (2), and carbide alloy sliver (3) adopts the dovetail mode to be connected with cutter hub (2).
2. the top gem of a girdle-pendant reamer of cutter hub carbide inserts sliver according to claim 1, the length that it is characterized in that carbide alloy sliver (3) equal targeting part from cutter hub (2) until the length of abrasive stick rear end.
