Description
Technical field
This utility model relates to the device of a kind of eccentric shaft locking, belongs to mechanical equipment technical field, is mainly used in stretching
Locking between arm and principal arm.
Background technology
This utility model is applied to plant equipment, mainly solves the locking problem of eccentric shaft.As it is shown in figure 1, it is existing at present
Solution be that square is processed at the two ends of eccentric shaft, the fixed plate of positioning eccentric shaft uses sector, fan-shaped circle centre position
It is processed into the square matched with eccentric axle head, covering of the fan is processed long arc-shaped holes, be used for adjusting with fixing.Bolt is penetrated arc
Shape elongated hole is fixed by pretightning force with the link on the telescopic arm of machinery, it is ensured that telescopic arm is parallel with principal arm after skidding off.But this
After kind of locking mechanism is given a shock, it is easy to loosen and even come off, cause fixed plate to rotate, it is impossible to location, increase roller and
Gap between principal arm guide rail, it is impossible to ensure linearity when telescopic arm stretches out and between principal arm, causes telescopic arm to rock, and reduces and makees
Industry efficiency.The square spindle nose of eccentric shaft is by bigger shearing force simultaneously, easily weares and teares, often changes when need to keep in repair.
Summary of the invention
The purpose of this utility model is the defect in order to overcome existing device, holds to solve existing eccentric shaft fixed form
The problem easily loosened, proposes a kind of eccentric shaft locking device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of eccentric shaft locking device, is made up of eccentric shaft, link, regulation of mental activities plate, bolt and packing ring.
One end spindle nose of described eccentric shaft keeps original square configuration, and other end spindle nose is processed as spline, described regulation of mental activities plate
For the spindle that middle wide two ends are narrow, in the middle of it, it is machined with the internal spline matched with described eccentric shaft spline oblique crank Z head, two ends
One connecting hole of each processing, is connected fixing to eccentric shaft and regulation of mental activities plate by spline, by bolt is passed connecting hole by regulation of mental activities
Plate is fixed on link, increases the frictional force between bolt and regulation of mental activities plate by packing ring, prevents it from slipping because of vibrations.
Using method:
Eccentric shaft locking device is arranged in plant equipment, with the square of spanner clamping eccentric shaft one end, by rotation
Transferring eccentric adjustment axle, after regulation gap is suitable, the other end adjusts regulation of mental activities plate and is connected with the spline of eccentric shaft, makes on regulation of mental activities plate
Two connecting holes be bolted with the circular hole on link, now adjust gap be in optimum Working.
Beneficial effect:
Contrast existing retaining mechanism:
Eccentric shaft is locked the spindle nose of one end and is used spline form, and its contact strength is high, and stress is concentrated more uniform, and abrasion is relatively
Dispersion and uniform, can reduce the flexural deformation of eccentric shaft, improve the service life of eccentric shaft；
Even if vibrating during Shi Yonging, bolt looseness, regulation of mental activities plate also will not move, and remains to maintain the lock status；And it is fan-shaped
Regulation of mental activities plate, once bolt looseness, regulation of mental activities plate will rotate along with the long arc-shaped holes adjusting bolt, cause locking to be lost efficacy；
Reducing frequency of maintenance, the locking device fastening after improvement is more stable, saves the cost of manual maintenance.
In sum, the device that the utility model proposes, simple in construction, it is simple to make and operate, strengthen eccentric shaft
Locking effect, effectively prevents from loosening the telescopic arm dancing caused between telescopic arm and principal arm, it is ensured that work efficiency, also subtracts
Lack the abrasion to eccentric shaft spindle nose, reduced the frequency that maintenance is changed, saved cost.

Fig. 1 is existing retaining mechanism sector fixed plate structure schematic diagram；
Fig. 2 is this utility model one eccentric shaft locking device structural front view；
Fig. 3 is this utility model one eccentric shaft locking device structure left view.
Reference: 1-bolt, 2-packing ring, 3-regulation of mental activities plate, 4-link, 5-eccentric shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiment of the present invention is elaborated.
A kind of eccentric shaft locking device, its structure as shown in Figure 2 and Figure 3, including with lower part: bolt 1, packing ring 2, regulation of mental activities
Plate 3, link 4, eccentric shaft 5；
Wherein: bolt 1, for regulation of mental activities plate 4 is fixed on link 4；
Packing ring 2, is used for preventing bolt 1 from loosening；
Regulation of mental activities plate 3, for adjusting and fixed eccentric shaft 5；
Link 4, for setting-up eccentricity shaft locking device；
Eccentric shaft 5, is used for adjusting gap.
The annexation of above-mentioned ingredient is: eccentric shaft 5 and regulation of mental activities plate 3 are connected by spline, regulation of mental activities plate 3 and link
4 are connected by bolt 1 and packing ring 2.
Preferably, fix for ease of regulation of mental activities plate 3, described link 4 has multiple adjusting hole for adjusting regulation of mental activities plate 3
Installation site.
The specific works process of this device is as follows: penetrated by eccentric shaft 5 in link 4, with spanner clamping eccentric shaft 5 one end
Square, come the position of eccentric adjustment axle 5 by rotation.After regulation gap is suitable, by regulation of mental activities plate 3 and eccentric shaft 5 another
End spline fitted, clamping eccentric shaft 5, then use bolt 1 and packing ring 2 to be fixed on link 4 by regulation of mental activities plate 3, make eccentric shaft 5
Position is fixed relative to link 4, now adjusts gap and is just in optimum Working.
Although combining accompanying drawing to describe embodiment of the present utility model, it will be apparent to those skilled in the art that
On the premise of without departing from this utility model principle, it is also possible to make some deformation and improvement, these also should be regarded as belonging to this reality
With novel protection domain.
