Description
Technical field
A kind of auger spindle locking device sawed on drilling machine tool is the utility model is related to, belongs to saw drilling machine tool equipment technical field.
Background technology
Combined saw drilling machine tool is made up of saw and drilling machine, and it can be in a bigger size range, to difference
Kind rail carries out sawing simultaneously and both ends jewel hole beats mouth.Combined saw rig bed apparatus rig is mainly by rig feed unit, brill
Machine main shaft drives, the assembling of rig axle and the deep-controlled unit of rig are formed.Drilling machine auger spindle fit on be mounted with an auger spindle and
Bearing support axially position locking nut, play auger spindle and bearing support axially position locking effect.
The auger spindle and bearing support axially position locking nut of auger spindle fit on installation mainly have two classes：General self-locking
Nut structure and the locking locking nut structure of elastic brake shoe locking.
It is general Self-lock nut structure, the locking nut of this structure, part material is high-quality referring to the drawings 1,2
Carbon spring steel, it is not easy to remove due to easily getting rusty after working long hours.Pretightning force locking is locking between relying solely on screw thread, is shaking
Start building under the conditions of work, easily loosen, positioning is unreliable；
It is the locking locking nut structure of elastic brake shoe locking, the locking nut of this structure is arranged on referring to the drawings 3,4
On auger spindle, the cantilever threaded body collet threaded axle of annular arc groove will be cut with, reach and be accurately positioned the effect of tightening.But in life
During producing use, after finding locking nut work a period of time of this structure, auger spindle and bearing support axially position loosen,
Axial gap is produced, causes auger spindle assembling seal assembly and bit damage, saws drilling machine cisco unity malfunction；It additionally, there are cantilever
The elasticity that threaded body works long hours weakens, and amount of elastic deformation diminishes, and causes not easy to remove, and need to destroy part during maintenance can just tear open not
Get off, cause maintenance cost excessive, maintenance time is long, and greater loss is brought to enterprise.
Utility model content
The utility model purpose is to provide a kind of auger spindle locking device sawed on drilling machine tool, and drill bit can be avoided to drill
Cheng Zhong, locking nut axially position loosen, and auger spindle is produced axial gap, cause auger spindle assembling sealing or bit damage, solve
Problem present in background technology.
The technical solution of the utility model is：
A kind of auger spindle locking device on saw drilling machine tool, include outer groove, locking screw nail, inner groove, axial nut rotation
Turn hole, radial direction nut rotating hole and locking nut, the outer circumference direction of locking nut are provided with outer groove, locking nut it is interior
Side circumferencial direction is provided with inner groove, and the end face of locking nut is provided with multiple locking screw nail and multiple axial nuts rotate
Hole, the outer surface of locking nut are provided with radial direction nut rotating hole.
The locking nut is round nut.
Locking screw nail and axial nut rotating hole on the locking nut end face are four.
Four locking screw nail and four axial nut rotating holes on the locking nut end face are along locking nut end face
Circumferencial direction uniform intervals arrangement.
Using the utility model, after locking nut is assembled on auger spindle, pass through the locking in locking screw nail
The pretightning force of screw makes walled metallic structure between inner groove and outer groove produce elastic deformation, to by the spiral shell of inner groove both sides
Line is inwardly drawn close together, by way of changing thread pitch, has the function that screw thread positioning and locking anti-back.When equipment produces shake
After dynamic or usage time length, the thin-wall metal between inner groove and outer groove makes auger spindle and locking nut due to elastic reset effect
Between screw thread can remain locking state, so as to improve job stability.When repairing auger spindle assembling, locking is unclamped
Screw, the thin-wall metal elastic reset between inner groove and outer groove, dismounting also become easier to.
The beneficial effects of the utility model are：The locking device is complete by the functionality advantage of common locking nut and disk spring
U.S.A combines, solve because cause after part long-time use parts get rusty or load effect be deformed, it is impossible to tear open
The problem of unloading, maintenance efficiency is improved, reduce maintenance cost and time.Also solve causes work because anti-loose structure is bad
It is long or under vibrating conditions to make the time, causes operating accuracy to decline or the problems such as parts damages because locking nut loosens.Should
Locking device uses high-quality stainless steel spring material, after it is worked long hours, non-corrosive and excellent elasticity, is not damaged in dismounting
Hinder each parts of connection, greatly reduce maintenance cost, improve maintenance efficiency, extend auger spindle assembling uses the longevity
Life, protect other important spare parts of connection.

Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 5,6, a kind of auger spindle locking device sawed on drilling machine tool, outer groove 1, locking screw nail 2, inner ring are included
Groove 3, axial nut rotating hole 4, radial direction nut rotating hole 5 and locking nut 7, the outer circumference direction of locking nut 7 are provided with
Outer groove 1, the inside circumference direction of locking nut 7 are provided with inner groove 3, and the end face of locking nut 7 is provided with multiple locking screws
Nail 2 and multiple axial nut rotating holes 4, the outer surface of locking nut 7 are provided with radial direction nut rotating hole 5.
In the present embodiment, locking nut 7 is round nut, using high-quality stainless steel spring material, in locking nut 7
It is cylindrical to open 2mm wide, diameter 44, the outer groove 1 apart from end face 7mm, process that 2mm is wide, diameter in the inner side of locking nut 7
