Description
Technical field
This utility model relates to the dismantling technology field of track vehicle body structure rivet, is specifically related to a kind of HUCK and takes out
Core rivet cold riveting dismounting special auxiliary device.
Background technology
Draw beam is the key position of rail vehicle, and the quality of connection of draw beam and coupler seat has influence on the driving peace of car load
Entirely, but in the running of vehicle, owing to being affected by natural conditions, light weight and the effect of load-carrying, both are not
Evitable collide, the impact such as abrasion, the problem that bolt looseness between parts, rivet rupture easily occurs, badly influences
The safety of car load.The staking connected mode of HUCK (Haake) rivet efficiently solves the fastening that draw beam position is caused because of vibrations
The problems such as part loose or dislocation, and be increasingly widely applied in track vehicle body structure.Along with the safety to rail vehicle
Property ask the raising of requirement, require riveting quality is strict, and effective grip scope of HUCK rivet is minimum (such as,
C50L90-BR24-16GA carbon steel rivet thickness is 25.4mm～31.75mm；C50LR-BR24-20GA carbon steel rivet
Thickness is 31.75mm～38.1mm), therefore be difficult in the fabrication process once the grip of whole rivets be reached zone of reasonableness
Within, when i.e. riveting gap does not reaches standard-required, it is necessary to again rivet, remove the rivet riveted, this implementation Process
Difficulty is relatively big, and product is existed potential safety hazard, controls bad easy injury material itself.
The most conventional method removing rivet has: the drill bit of electric drill is facing to the middle low cruise of nail by hand, or
Rivet head is ground off with angle grinding machine.But, use electric drill that low velocity in the middle of rivet nail rod rotates the method efficiency removing rivet
Low, speed is slow, and stress surface is little, easily changes Impact direction, makes rivet that materials and parts are produced secondary impact, there is potential safety hazard.Adopt
The method grinding off rivet head removal rivet with angle grinding machine has limitation, if angle grinding machine cannot be ground to this portion in angle at rivet head
Position, then cannot remove, and angle grinding machine sphere of action is relatively big, is difficult to control it and does not contact materials and parts, the materials and parts that easy damaged is riveted.
Utility model content
There are inefficiency, easy damaged materials and parts to solve the method for the defective rivet of existing removal, have potential safety hazard
Technical problem, this utility model provides a kind of HUCK self-plugging rivet cold riveting dismounting special auxiliary device, and it can be the rapidest
The defective rivet of removal, the mother metal of materials and parts can't be damaged, avoid in removal process simultaneously and cause drill bit or defective riveting
The nail secondary impact to other materials and parts, simple and quick, substantially increase production efficiency.
The technical scheme that this utility model solution technical problem is taked is as follows:
HUCK self-plugging rivet cold riveting dismounting special auxiliary device, it includes pipe box and at least two bolt, pipe box axial
Being provided with at least two screwed hole, the axis of each screwed hole is positioned at approximately the same plane, the axis of the most adjacent two screwed holes
Wire clamp angle is identical；Pipe box be radially provided with a diameter bore, the upper end diameter of diameter bore be less than lower end diameter, diameter bore
Upper end diameter less than the rivet cap external diameter of rivet to be removed, outside the lower end shape of diameter bore is with the rivet cap of rivet to be removed
Shape is mated, and the lower end diameter of diameter bore is than above-mentioned rivet big 4mm～8mm of cap external diameter；The spiro rod length of each bolt compares pipe box
Big 6mm～18mm of wall thickness, each bolt is threadeded with pipe box by a screwed hole.
The number of above-mentioned bolt and screwed hole is 2, and the axis angle of two screwed holes is 180 °.
The beneficial effects of the utility model are as follows:
1) mode removing defective rivet compared to other, this device can effectively be protected by riveting materials and parts mother metal the most drilled
The instrument injuries such as head and angle grinding machine.
2) this device effectively utilizes the drill bit impulsive force to rivet, i.e. removable defective rivet, raising life in the short time
Produce efficiency.
3) this device can effectively prevent the hidden danger caused because of Drill Crack or the splashing of rivet breaking part metal derby
Generation, protection operator safety.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of this utility model HUCK self-plugging rivet cold riveting dismounting special auxiliary device.
Fig. 2 is the perspective view of the pipe box in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further details.
As depicted in figs. 1 and 2, HUCK self-plugging rivet cold riveting of the present utility model dismounting special auxiliary device includes pipe box 1
With at least two bolt 2, pipe box 1 be axially arranged with at least two screwed hole 1-1, the axis of each screwed hole 1-1 is respectively positioned on
In approximately the same plane, the axis angle of the most adjacent two screwed hole 1-1 is identical；Pipe box 1 be radially provided with a diameter bore
1-2, the upper end diameter of diameter bore 1-2 is less than lower end diameter, and the upper end diameter of diameter bore 1-2 is less than the riveting of rivet to be removed
The rivet cap form fit of head of a nail external diameter, the lower end shape of diameter bore 1-2 and rivet to be removed, the lower end of diameter bore 1-2
Diameter is than above-mentioned rivet big 4mm～8mm of cap external diameter；Spiro rod length 6mm～18mm bigger than the wall thickness of pipe box 1 of each bolt 2, often
Individual bolt 2 is threadeded with pipe box 1 by a screwed hole 1-1.
If the number of bolt 2 and screwed hole 1-1 is 2, then 180 °, the angle position, axis of two screwed hole 1-1, i.e.
It is symmetricly set on the two ends of pipe box 1；If the number of bolt 2 and screwed hole 1-1 is 3, then the axis of three screwed hole 1-1
Angle is 120 °, and the rest may be inferred, no longer enumerates.
The work process of this utility model HUCK self-plugging rivet cold riveting dismounting special auxiliary device is as follows:
Rivet cap size according to defective rivet to be removed and the size of required diameter bore 1-2 lower end diameter, choosing
Select the pipe box 1 of corresponding size；Size according to rivet bar and the size of diameter bore 1-2 upper end diameter, select corresponding electric drill to bore
The size of head, general diameter bore 1-2 upper end diameter 0.1mm～0.3mm bigger than bit diameter.Pipe box 1 is by common rustless steel
Material makes, and meanwhile, the interior surface of diameter bore 1-2 upper end needs to make Quenching Treatment in the course of processing, to increase at this
Hardness；The spiro rod length of bolt 2, between 18mm～30mm, can be chosen according to the wall thickness of selected pipe box 1.
After above-mentioned pipe box 1 and bolt 2 are chosen, being enclosed within defective rivet by pipe box 1, the bolt 2 tightening two ends is fixed
After defective rivet, being pierced in pipe box 1 by drill bit by the upper end of the diameter bore 1-2 of pipe box 1, drill bit can bore broken rivet accurately
Nail rod, after the bolt 2 of loose ends, defective rivet can easily remove.
