When needing to use shock resistance motor to carry out bore operation, first the fastening bolt of coupling assembly is removed, then Anchor ear removes, and the limited block on the right side of motor mounting groove is taken out, shock resistance motor is moved right along motor mounting groove, right connection Disk is separated with left terminal pad, and rectangular channel of the rectangular block between left terminal pad and right terminal pad is fallen down, shock resistance motor Taken out out of motor mounting groove, take out a drill bit and connector, six prism structures of drill bit are inserted into the installation of six prisms In hole, and straight pin is inserted by drill bit and connects axis connection, it is then corresponding with right terminal pad using the drilling terminal pad of connector, And rectangular block is placed between drilling terminal pad and right terminal pad, reusing fastening bolt will drilling terminal pad and right terminal pad Connection.Then bore operation can be carried out by holding two handles.

For the utility model in bore operation, two hands of operator hold a handle respectively, drill bit alignment boring point, resist The the first main shaft left end for impacting motor is clutch end, and drill bit can receive stronger axial impact in drilling process, when the When one main shaft left end is by axial impact, the first main shaft can play to the right suddenly, the guide groove on the first main shaft is along thrust bearing The guide block being fixedly installed on circle moves right, and the first main shaft right-hand member will drive plunger, plunger actuation compression spring top pressure to the right Closure plate, meanwhile, plunger produces thrust to hydraulic oil, and the hydraulic oil in inner barrel is squeezed into toroidal cavity by oilhole, by Moved from left to right in plunger, the sealing shroud on plunger can block the oilhole on inner barrel, between inner barrel and annular housing Oilhole passage reduces, and the pressure increase of hydraulic oil, hydraulic oil depressurize left and right with regard to that can play good buffering in inner barrel, compress bullet Spring also functions to good cushioning effect, so it is avoided that thrust bearing receives impulsive force, is effectively protected thrust bearing.First The cooperation between the guide block being fixedly installed on guide groove and thrust bearing inner ring is opened up on main shaft to be used to transmit moment of torsion, is also convenient for simultaneously First main shaft is axially moveable, and under conditions of having gap between the first main shaft and thrust bearing inner ring, also ensures that the first master Axle does not produce friction in rotation process with thrust bearing inner ring.Jump ring is used for the work for positioning right side thrust bearing axial direction position With.

When compression spring is in the fully extended state, the right part of compression spring contacts with right end cap, while guide block Right part contacts with the right part of guide groove；So when the first main shaft does not receive axial impact force, make the first main shaft in axial side Positioning upwards.

The volume of annular housing is less than the volume inside inner barrel, and the volume of hydraulic oil is equal to the volume inside inner barrel, After being full of hydraulic oil so in annular housing, still some hydraulic oil inside inner barrel, plunger is avoided by compression spring Very stiff and demanding stress is produced when being pressed onto the most short limit.

The utility model is played good anti-Axial Shock Load, compared using the double buffering guarantee of hydraulic pressure and spring Only set a compression spring to enter row buffering, make the motor that there is stronger anti-axial impact.

The utility model passes through rectangular block using left terminal pad and right terminal pad and right terminal pad and drilling terminal pad Moment of torsion is transmitted, fastening bolt will not be by shearing force, and fastening bolt is functioned only as left terminal pad and right terminal pad and right company Connect disk and drilling terminal pad is axially fitted and connected, rectangular block is installed in rectangular channel will not also take off in high-speed rotation Fall, reliability is stronger.

Using the prism structure of drill bit six and the mounting structure of six prism mounting holes between drill bit and connecting shaft, so transmit and turn round Square is stronger, circumferentially positioned to drill bit progress using straight pin, is easily installed and dismantles drill bit.

In summary, the utility model small volume, it is easy to carry or carries, suitable for smaller space or avoids damage to big The drawing construction operation in crops is measured, and with two kinds of functions of drawing and drill, these all bring to associate power workmen Great convenience, it is easy to operation, extend the service life of shock resistance motor.
