Embodiment
Below in conjunction with attached drawing illustrated embodiment, the utility model is described in further detail, but the utility model does not limit to
In following embodiments.
Utility model people has made intensive studies the friction phenomenon of existing mechanical automatic table (referring to Fig. 2), finds
Eccentric wear reason：The larger autoplugger bias of quality is fixed on the top of shaft, and countershaft applies the moment of torsion of off-axis；And
On the other hand, due to thickness in terms of limitation, the bearings that the shaft of autoplugger is formed by single ball, each component in shaft
In a camber line, (camber line was located at axis to the force localization for each ball that (mainly outer shroud 2, pressure ring 8 and inner ring) is subject to
In one plane of line), each ball is accordingly subject to the reaction force of each component in shaft at the same time；Wherein there was only part ball
(quantity accounts for the half of whole balls；It is mainly situated in several balls of autoplugger bias side and corresponding another
Several balls of side) it is subject to the reaction force of shaft just to form the opposing torque (arm of force of opposing torque of balance aforementioned torques
Very little)；It is sufficiently large therefore, it is necessary to reaction force, required opposing torque could be obtained；A points, D points especially in outer shroud
Region (referring to Fig. 2), the B points region in pressure ring, the C points region in inner ring, these regions are primarily subjected to the branch of ball countershaft
Support force, and corresponding reaction force is produced, and the vertical range that the arm of force for forming opposing torque is only B points to C points (is only 0.3-
0.5mm), thus the active force that bears of these regions it is larger, easily produce abrasion aggravation phenomenon.
The rotating shaft positioning structure (as shown in Figure 1) of autoplugger provided by the utility model, including pass through ball bearing structure
It is rotatably positioned the shaft 1 in clamping plate 9, the shaft top fixed autoplugger 6 of screw 7；These structures with it is existing automatic
The structure of hammer is similar.
The improvement of the utility model is：The ball bearing structure further includes two rows of balls 5 (being typically ceramic balls)；
Outer ring of the outer shroud 2 as bearing, the inner ring (alternatively referred to as inner ring) of the periphery of shaft as bearing, it is radially fixed that ball is carried out
Position.The annular isolation piece 2-1 of the also embedded two rows of ball spacing of a holding, the outer diameter part of the annular isolation piece between two rows of balls
Divide to be connected as a single entity with the inner wall of outer shroud 2 and (can also be expressed as：On the inner wall of outer shroud formed one toward internal diameter direction protrude annular every
From piece 2-1, it is used to limit the beeline between two rows of balls between the two rows of balls of spacer insertion).Inner ring and outer shroud
Coordinate the control for also having the function that equivalent to guide post guide sleeve, to be more advantageous to bearing clearance.
Raised head face of the upper and lower ends of two rows of balls respectively by pressure ring and positioned at shaft bottom carries out axial limiting；Institute
Pressure ring is stated to be positioned in shaft by press fit (i.e. tight fit).
(referring to Fig. 1) in embodiment 1：The fixed autoplugger in top of shaft, outer shroud and Boards wall；Shaft bottom it is convex
Platform is upper bar gear 1-1, and the end face of upper bar gear is used to carry out ball axial limiting (unidirectional spacing, to make it not move down)；
The top of shaft is accordingly disposed with that (pressure ring leads to for the pressure ring 8 to ball axial limiting (unidirectional spacing, make it not move up)
Cross press fit to be positioned in shaft)；Pressure ring, the end face of upper bar gear are positioned on outer shroud by ball respectively, are also acted as flat
The effect of spherical bearing.When autoplugger rotates, upper bar gear is driven to rotate by shaft, so as to fulfill the operation of clockwork spring is tightened.
(referring to Fig. 3) in embodiment 2：The shaft and Boards wall, autoplugger are fixed with outer shroud, the excircle system of outer shroud
It is made bar gear.When autoplugger rotates, by driving upper bar gear to rotate, so as to fulfill the operation of clockwork spring is tightened.
The top of the shaft is up-small and down-big step structure, and the pressure ring is positioned at smaller straight by press fit
On the periphery at footpath position.
Preferably, the shaft is hollow shaft；Have and the matched screw hole of screw in favor of making.
Since single ball is changed to double-row balls, the stress of each component significantly improves in the utility model；
Wherein (referring to Fig. 3)：The E points region of pressure ring, the G points of outer shroud, H points, L points, M points region, the F points of shaft, K points, J point regions by
To pressure can synthesize opposing torque.As seen from the figure：Since the arm of force (distance at two rows ball center) is than existing
Technology has the increase of decades of times, thus the active force for synthesizing opposing torque can accordingly reduce decades of times；Obviously, friction phenomenon obtains
The change of essence, also solves the excessive disadvantage in conventional autoplugger gap, is conducive to energy conversion, and can increase rotation
Inertia, increase service life.
Since single ball is changed to double-row balls, the length of shaft has increased slightly；Therefore the structure of autoplugger is adapted to
The change of property, to keep integrally-built thickness constant.Wherein, the gap between autoplugger bottom and clamping plate, can be from original
0.25mm is kept to 0.15mm, accordingly increases the thickness of autoplugger hammer body and the rotary inertia of autoplugger.
