Description
The utility model relates to a kind of electric rock drilling machinery that is used for mining and infrastructure industry rock drilling.
The utility model is to " cam spouse formula electric rock drill " a kind of improvement design (ZL93203643.0).The key Design thought of cam spouse formula electric rock drill is with rotatablely moving that motor is exported, and directly drives impact cam by impactor and produces ballistic motion and change the pricker motion, has removed a series of transmission mechanisms and the rotating drill rod mechanism of existing electric rock drill from.But show through trial-production and rock drilling test, still there are the following problems for cam spouse formula electric rock drill: 1, buffering and absorbing problem are not considered in this machine global design, it is unreliable to make that some component connect, very easily damage: 2, because the problems referred to above, for machine is used, the movement travel of cam has to reduce, be hit and vibrate to alleviate machine, the low problem of merit and the stroke deficiency impacts: 3, when increasing cam stroke for improving ballistic work, because the also corresponding increase of the average pressure angle of cam, this lateral force that causes impactor to act on the cam contour also increases, make the cam rotation frequency improve and impingement rate decline, impact velocity reduces, thereby is difficult to improve ballistic work.
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 and adjustable are provided.
Technical solution of the present utility model is: this is adjustable, and the ballistic work electric rock drill comprises casing, motor, flange, bolt, rotor axis of electric, impactor, cam and pricker seat, it is characterized in that: impactor is formed by connecting by spline by impacting body and impactor axle, the impactor axle is by the middle part of roller bearings at casing, buffer rubber gasket is equipped with at the two ends of impacting body, impact and be processed with two impact melons on the body, this impact pawl matches with the impact curved surface and the cam return curved surface of cam respectively, be provided with anti-rotation member between cam and the pricker cover for seat tube, a pricker cover for seat tube cylindrical left side, right both sides are respectively equipped with external splines, this external splines turns round the clutch moving plate with resistance respectively and the pressure regulating block connects, resistance is turned round between clutch moving plate and the pressure regulating block and is provided with compression spring, on the flange of casing pricker seat section right part, be fixed with resistance and turn round the clutch stator, resistance is turned round the clutch stator and is turned round the clutch moving plate with resistance and be meshed, pricker cover for seat tube is provided with the pressure regulating block that is processed with the flute profile slideway on it, relative 180 degree offer two axial elongated slots on the casing that is positioned at pressure regulating block place, the shift fork of adjusting rod snaps in the flute profile slideway of regulating block by this axial elongated slot, adjusting screw(rod) is installed in the screw of offering on the flange of through hole on the adjusting rod and pricker seat section right part, and the endoporus of pricker cover for seat tube is processed into hexagonal or spline.
In the utility model, the anti-rotation member that is provided with between cam and the pricker cover for seat tube preferably has the axial elongated slot of circular arc on the left side of cam external cylindrical surface, pricker cover for seat tube the right inner circumferential side also has the axial elongated slot of corresponding circular arc, is provided with ball in these two elongated slots.
In the utility model, the axial elongated slot of circular arc is offered on the right that is preferably in the cam external cylindrical surface, is provided with ball in the elongated slot, and the vacant partial-length of elongated slot is equal to or greater than the stroke of cam, and ball is supported in cam in the stage casing of casing.
Owing to adopt two ends that the combined type impactor of buffer rubber gasket is housed, can absorb big anti-force and anti-issuable high-frequency excitation on the utility model, protection mechanism and part are not damaged.Owing between cam and the housing, be provided with an amount of ball between cam and the pricker cover for seat tube, just original sliding friction being become axially-movable is rolling friction, is sliding friction and rotatablely move, thereby has improved frequency of impact and ballistic work.
The endoporus of the utility model pricker cover for seat tube is made hexagonal or spline, make it and the pricker seat between can not produce relative rotation, under the effect of compression spring, the stator that clutch is turned round in resistance offers moving plate and offers pricker cover for seat tube and the certain resistance torsional moment of pricker seat successively.Impact the moment of torsion that lateral force that pawl acts on cam offers cam, during only greater than the frictional resistance sum of this resistance torsional moment and hammer drill and rock, hammer drill just can rotate.Therefore, the active force of compression spring has been adjusted anti-sticking pricker moment on the one hand, has adjusted the rotational frequency of hammer drill on the other hand, thereby has realized the adjusting of cam frequency of impact and machine ballistic work.The adjusting of compression spring active force is to realize with respect to the position of casing by the shift fork of adjusting screw(rod) adjusting adjusting rod.
The utility model had both overcome the various shortcoming of former machine, and simple, lower to the hardness fast advantage of rock rock drilling that the while has kept original machine mechanism again is specially adapted to the different rocks of hardness range broadness and the high speed rock drilling and the drilling of building materials.The utility model is rational in infrastructure, dependable performance, long working life, ballistic work big and can regulate.
