Effect.
Technical solution 7 is further improved on the basis of 1 ~ 3 any technical solution of technical solution, and the import is equipped with certainly
Dynamic feeder.Help to enhance the production efficiency that oscillating bearing of the invention swims clearance adjustment apparatus.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that oscillating bearing clearance of the invention adjusts Installation practice 1；
In attached drawing: 1, first adjusting bolt；2, second bolt is adjusted；3, tubular shell；4, roller；5, inlet baffle；6, it exports
Baffle；7, feeding-passage；8, vibrator feeder.
Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment 1 of oscillating bearing trip clearance adjustment apparatus of the invention, as shown in Figure 1, including tubular shell 3, cylinder
Shape shell 3 is cylindrical tube shape, and cylindrical barrel shell 3 is horizontal positioned, and the tubular shell 3 in the present embodiment is steel material
Expect, roller 4, the rotation of motor (not shown) drive roller wheel 4 and 4 rotation direction of roller are coaxially installed with inside tubular shell 3
For counterclockwise.Roller 4 is located at 3 center of tubular shell and forms circular ring shape channel, tubular shell with tubular shell 3
Radially there is the inlet and outlet penetrated through with circular ring shape channel.Circular passage between import and outlet forms rolling channel,
Oscillating bearing to be processed is sent into rolling channel and by the frictional force between roller 4 and oscillating bearing along roller 4 by import
Rotation direction rolls.Rolling channel is gradually reduced in the size of roller 4 radially along 4 rotation direction of roller, i.e. H1> H2> H3,
The reason of designing in this way is that oscillating bearing in rotation process, rolls channel and get in the size of roller 4 radially in rolling channel
Next smaller small to achieve the purpose that press oscillating bearing clearance, it is to keep away why the size for rolling channel, which is arranged to successively decrease,
Exempt from because rolling channel size reduce suddenly so that oscillating bearing to be processed squeeze it is bad.
In order to increase the move distance of oscillating bearing to be processed in rolling channel, the section for rolling channel is U-shaped arc
Shape.It feeds and discharges for the ease of oscillating bearing, the import and outlet in the present embodiment are horizontally disposed, and in import and cylinder
Inlet baffle 5 is installed in the upper end of 3 contact position of shape shell, keeps off in outlet and the upper end installation outlet of 3 contact position of tubular shell
Plate 6, is arranged inlet baffle 5 and outlet damper 6 effectively prevents oscillating bearing and shifts after entering rolling channel, plays
Certain position-limiting action, and axis where import and rolling channel form angle α, and 90 ° of < α < in the tangent line of import
180 °, the benefit designed in this way is that oscillating bearing to be processed can more smoothly enter rolling channel.
The oscillating bearing that different clearance sizes require is adjusted in order to enable oscillating bearing of the invention to swim clearance adjustment apparatus,
The size in the rolling channel in oscillating bearing trip clearance adjustment apparatus of the invention can be adjusted freely.Rolling is freely adjusted in order to reach
The purpose of pressure passageway size, on the outside of tubular shell 3 tool there are two spaced adjusting bolt, respectively first adjust bolt 1,
Second adjusts bolt 2.Bolt is adjusted by precession and screws out distance between fine tuning tubular shell 3 and roller 4, to reach adjusting
Roll the purpose of size of the channel in roller 4 radially.First in the present embodiment is adjusted between bolt 1 and the second adjusting bolt 2
It is arranged every 90 °, the size that least adjusting bolt adjusts entire rolling channel can be used in setting in this way, this is in certain journey certainly
Cost of manufacture of the invention is reduced on degree.There is fixed block, fixed block and tubular shell 3 on adjusting bolt in the present embodiment
External object, which is fixedly connected, plays the role of fulcrum.In addition, it is necessary to which explanation is adjusting bolt in the present embodiment in precession
During back-out, in the size of roller 4 radially small change occurs for rolling channel, while exporting the width with import
Small change occurs, but does not influence oscillating bearing disengaging rolling channel, that is to say, that the adjusting bolt in the present invention plays micro-
The effect of tune, rolling channel are mainly determined by the distance between roller 4 and tubular shell 3 in the size of roller 4 radially.
Oscillating bearing of the invention swims clearance adjustment apparatus to enhance the convenience and agility of charging, the end of import
Automatic charging machine is installed, the automatic charging machine in the present embodiment is vibrator feeder 8, in other embodiments automatic charging
Machine can also be replaced by other kinds of automatic charging machine.In order to make stable the entering of oscillating bearing roll channel, vibrator end
Feeding-passage 7 is connected between portion and import.Vibrator feeder 8 in the present embodiment is vibrator feeding in the prior art
Machine, the specific structure about vibrator feeder 8 are not described in detail herein.
Oscillating bearing trip clearance adjustment apparatus of the invention is in use, be placed on vibrator for oscillating bearing batch to be adjusted
8 the inside of feeder is adjusted the size of H2 and H3 by the first adjusting bolt 1 and the second adjusting bolt 2, guarantees H1 > H2 >
H3, to meet the requirement that oscillating bearing adjusts clearance.The switch of vibrator feeder 8 is first opened, then opens the switch of roller 4.
Oscillating bearing can enter rolling channel after inlet baffle by vibrator feeder 8 with correct position, when roller 4 rotates
When, roll the frictional force that the oscillating bearing in channel generates under the rolling of roller 4 and tubular shell 3 by outer ring and roller 4
Clearance needed for advancing in the rolling channel become narrow gradually and obtain product.
Oscillating bearing of the invention swims the specific embodiment 2 of clearance adjustment apparatus, the oscillating bearing clearance tune in the present embodiment
Engagement positions are served only for rolling the oscillating bearing of fixed clearance, therefore the oscillating bearing of the present embodiment trip clearance adjustment apparatus is not provided with adjusting
Bolt.Other are same as Example 1, repeat no more.
Oscillating bearing of the invention swims the specific embodiment 3 of clearance adjustment apparatus, and the adjustment structure in the present embodiment is lead screw
Nut structure, other are same as Example 1, repeat no more.
Adjustment bolt in above-described embodiment can be more than two arbitrary numbers；Automatic charging machine can also be not provided with.
