Abstract
The utility model relates to part retaining mechanisms in a kind of extruder, including sliding part, piston rod, nut, locking nut and several outer-hexagonal bolts, the sliding part is arranged on the piston rod and by nut and tight, locking nut is set on the outside of the nut, circumferentially several through-holes on the locking nut, corresponding position is distributed the threaded hole of identical quantity on the nut, and the outer-hexagonal bolt passes through the through-hole and nut and locking nut are locked by threaded hole.The utility model retaining mechanism is arranged locking nut on the outside of nut, and nut and locking nut and tight are increased the fastness of locking by outer-hexagonal bolt；In addition, check washer is arranged between every two adjacent outer-hexagonal bolts, a locking effect is generated, locking fastness is further enhanced, avoids nut loosening.
Description
Technical field
The utility model relates to extruder fields, and in particular to part retaining mechanism in a kind of extruder.
Background technique
In the prior art, after the cylinder piston rod on extruder and sliding part (such as piston) are connect simultaneously with nut
Tightly, but since during the work time, piston rod frequently moves, screw thread bears dynamic loading, is easy to produce asking for nut loosening
Topic, influences equipment normal use.
Utility model content
It is in the prior art to solve the purpose of this utility model is to provide part retaining mechanism in a kind of extruder
The problem of fastening nut of piston rod and sliding part is easy to produce loosening.
The utility model provides part retaining mechanism in a kind of extruder, including sliding part, piston rod, nut, lock
Tight nut and several outer-hexagonal bolts, the sliding part are arranged on the piston rod and by nut and tight, the nut outside
Locking nut is set, and circumferentially several through-holes on the locking nut, corresponding position is distributed identical quantity on the nut
Threaded hole, the outer-hexagonal bolt passes through the through-hole and threaded hole and nut and locking nut is locked.
Further, the quantity of the outer-hexagonal bolt is even number, and is arranged between every two adjacent outer-hexagonal bolts
Check washer, the check washer are set on two outer-hexagonal bolts.
Further, the check washer with a thickness of 0.5-2mm.
Further, the material of the check washer is metal.
Further, the shape of the check washer is sector.
Beneficial effect using above-mentioned technical solutions of the utility model is:
Locking nut is arranged in the utility model retaining mechanism on the outside of nut, and passes through outer-hexagonal bolt for nut and locking
Nut is simultaneously tight, increases the fastness of locking；In addition, check washer is arranged between every two adjacent outer-hexagonal bolts, produce
A raw locking effect, further enhances locking fastness, avoids nut loosening.
Detailed description of the invention
Fig. 1 is part locking mechanism structure schematic diagram in the utility model extruder；
Fig. 2 is retaining mechanism part right view；
In attached drawing, parts list represented by the reference numerals are as follows:
1- sliding part, 2- piston rod, 3- nut, 4- locking nut, 5- outer-hexagonal bolt, 6- check washer.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.
As shown in Figure 1, part retaining mechanism in a kind of extruder of the present embodiment, including sliding part 1, piston rod 2, nut
3, locking nut 4 and several outer-hexagonal bolts 5, the sliding part 1 is set on piston rod 2 and by nut 3 and tightly, described
Locking nut 4 is set on the outside of nut 3, circumferentially several through-holes on the locking nut 4, corresponding position on the nut 3
It is distributed the threaded hole of identical quantity, the outer-hexagonal bolt 5 passes through the through-hole and threaded hole locks nut 3 and locking nut 4
It is fixed.In the embodiment, nut 3 is tentatively fixed sliding part 1 and piston rod 2 and tightly, and locking screw is arranged on the outside of nut 3
Mother 4, locking nut 4 is screwed into nut 3 there are when certain interval, reusing outer-hexagonal bolt 5 to tighten the two, increases locking
Fastness, avoid nut 3 loosen, wherein the quantity of outer-hexagonal bolt 5 can be 6,8 or 10.
As shown in Fig. 2, the check washer 6 of metal material fan shape is set between per two adjacent outer-hexagonal bolts 5,
The check washer 6 is set on two outer-hexagonal bolts 5 by outer-hexagonal bolt 5 after tightening, and gasket shape is broken curved to patch
It closes on the turret head of outer hex bolts 5, middle section, which also clamps, destroys its shape, it is allowed to generate a locking effect,
In, check washer 6 with a thickness of 0.5-2mm.
To sum up, locking nut is arranged in the utility model retaining mechanism on the outside of nut, and passes through outer-hexagonal bolt for nut
With locking nut and tight, the fastness of locking is increased；In addition, locking pad is arranged between every two adjacent outer-hexagonal bolts
Piece generates a locking effect, further enhances locking fastness, avoid nut loosening.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
