The purpose of this utility model is to overcome the existing defective of ZL93203643.0 patent, and a kind of rational in infrastructure, dependable performance, long working life, high-performance electric rock drill that ballistic work is big are provided.
Technical solution of the present utility model is: this modified cam spouse formula electric rock drill comprises casing, motor, bolt, flange, rotor axis of electric, impactor, cam and pricker seat.It is characterized in that: impactor is formed by connecting by key by impacting body and impactor axle, buffer rubber gasket is equipped with at two ends towards southern body, rotor axis of electric is connected with the impactor axle by spline, the impactor axle by roller bearings by interior cover, on the unsteady support set that overcoat and pin constitute, unsteady support set two ends are provided with buffer rubber gasket, two impact pawls that impact on the body match with the impact curved surface and the return face of cam respectively, be provided with anti-rotation member between casing and the cam, be provided with the spiral external splines at cam external cylindrical surface right-hand member, the internal helix spline engagement of this spiral external splines and spiral switch block, the external cylindrical surface of spiral switch block is connected with the driving link of directional clutch by feather key, be provided with stage clip between spiral switch block and the directional clutch driving link, the driving link of directional clutch and the engagement of the driven member of directional clutch, the pricker seat is connected with the directional clutch driven member by spline.
In the utility model, anti-rotation member between casing and the cam is to have axial circular arc elongated slot on the left side of cam external cylindrical surface, casing inner wall correspondingly also has axial circular arc elongated slot on the position, these two elongated slots are formed cylindrical raceway, be filled with ball in the raceway, the residue length of raceway is equal to or greater than the stroke of cam.
In the utility model, directional clutch adopts unequal-sided triangle jaw clutch.
The utility model is owing to adopt two ends that the combined type impactor of buffer rubber gasket is housed, and is supported on two ends and is equipped with on the unsteady support set of buffer rubber gasket, and like this, impactor is operated under the two-stage buffer protection, has overcome mechanism and part rapid wear problem effectively.Owing to be placed with an amount of ball in the raceway between casing and the cam external cylindrical surface, like this, just, become the axially reciprocating under the rolling friction state with the motion of original cam under the sliding friction state.
In the utility model, cam is when moving back and forth, and spiral switch block and clutch driving link make back rotation, order about clutch driven member and pricker seat one-directional rotation.
The utility model is not only overcoming the existing problem of existing cam spouse formula electric rock drill, and has reduced energy loss, has improved machine application life and reliability, has improved the ballistic work of machine.The utility model is applicable to medium and small bargh and individual, is used for the rock drilling and the drilling of rock and building materials.
