Abstract
The utility model provides a kind of composite cutter bit body, and comprise pick body and lower pick body two sections, two sections of material differences, its joint face is positioned at pick body head place.Upper pick body is the truncated cone shape that rear end, axle center is provided with boss, and hub head end is provided with the cylinder counterbore coordinated with hard alloy head, and boss is the frustum of a cone or cylindrical, and it is uniformly distributed external screw thread; Lower pick body, by the frustum of a cone and cylinder overall structure dimerous, is provided with the groove placing spring washer and the screw-threaded counterbore coordinated with upper pick body boss, is provided with the groove of a Joining clasp in barrel portion lower end in its hub head end.This structure is simple, and mounting or dismounting are convenient, solves pick because of alloy head serious wear or drop and directly scrap the problem of whole pick, greatly saves material, reduce costs, also reduce the labour intensity of workman.
Description
Technical field
The utility model relates to a kind of cutter, especially mining and highway structure mining machinery equipment on pick.
Background technology
Pick is widely used cut cutter in mining machinery, be mainly used in development machine, coal-winning machine, Lian Caiji, on the equipment such as excavator, it is main consumable part, pick-like bit is adopted soldering by pick body and hard alloy head two parts and made, hard alloy head is embedded in the shrinkage pool of pick body front end, pick body forms one for overall structure by cutting pick head and cutting pick handle, forging must be set level, make troubles to processing, in addition because be expendable part, after pick uses a period of time, due to hard alloy head alloy head serious wear or drop and directly scrap the problem of whole pick, consumptive material is large, cost is higher.
Utility model content
1. technical solution problem
For current due to hard alloy head serious wear or drop and cause scrapping of whole pick, consumptive material is large, the shortcoming of processing inconvenience etc., the utility model provides a kind of composite cutter bit body, when pick carbide head is scrapped, directly can change the epimere of pick body and retain hypomere continuation use, avoiding the waste of material, reduce cost.
2. technical scheme
The technical scheme that the utility model technical solution problem is taked is: described composite cutter bit body comprises pick body and lower pick body two sections, upper pick body is the truncated cone shape that rear end, axle center is provided with boss, and hub head end is provided with the counterbore coordinated with hard alloy head; Lower pick body, by frustum-conical portion and cylindrical cutting pick handle overall structure dimerous, is provided with the groove placing spring washer and the counterbore coordinated with upper pick body boss, is provided with the groove of a Joining clasp in cutting pick handle lower end in its hub head end.
Described composite cutter bit body, joint face is positioned at the head position of pick body, two sections of material differences, and upper pick body adopts the material that intensity is higher, and lower pick body adopts the material that intensity is lower.
Described composite cutter bit body, upper pick body boss is the frustum of a cone or cylindrical, it is uniformly distributed external screw thread, the counterbore of lower pick body hub head end has the internal thread matched with upper pick body boss screw thread, spring washer is placed in the groove of lower pick body, by the external screw thread boss spinning of upper pick body in the screw-threaded counterbore of lower pick body, link into an integrated entity.
3. the beneficial effects of the utility model
The utility model composite cutter bit body, structure is simple, and mounting or dismounting are convenient, when pick carbide head is scrapped, directly can change alloy head and upper pick body and retain pick body and continue to use, thus saving material, reducing costs, reduce the labour intensity of workman.
