Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As it is shown in figure 1, the coupling hitch according to embodiments of the present invention includes that first fixes seat
10, for being connected with by traction apparatus；Second fixes seat 20, for being connected with traction apparatus；Buffering
Device, two ends fix seat 10 and second respectively and fix seat 20 and be connected with first, and buffer unit includes delaying
Punching first fix seat 10 (the A direction shown in Fig. 1) in the first direction mobile impact and with
First direction is the sliding sleeve buffer gear rotating impact of rotary shaft.
Thus in the coupling hitch of the present invention, by traction apparatus and by traction apparatus between
Coupling hitch is set, during traction apparatus traction is by traction apparatus, coupling hitch
In sliding sleeve buffer gear relative displacement and rotation can occur when being hit by traction apparatus, slow down punching
Hit the impact on traction apparatus, improve the situation that traction apparatus stress is abnormal, lifting traction device
Service life, cost-effective.
It should be noted that, owing to being fixed seat 10 by the impact suffered by traction apparatus by first
Conduct and traction apparatus is produced impact, therefore the buffer unit in the present invention is to fix seat by buffering first
Impact suffered by 10 realizes slowing down traction apparatus the effect of impact.
As shown in Figure 1 to Figure 3, the sliding sleeve buffer gear in the embodiment of the present invention includes slide bar 30 He
Sleeve 40, slide bar 30 extends in a first direction, and slide bar 30 and sleeve 40 are along the length side of slide bar 30
To can relatively slide, and can relatively rotate with slide bar 30 for axle, sliding sleeve buffer gear passes through above-mentioned tool
Body structure realizes fixing the buffering of seat 10 mobile impact in the first direction to first and with first party
Impact to the rotation for rotary shaft.Wherein, slide bar 30 is arranged on first and fixes on seat 10, specifically may be used
Being to realize being connected by fixing the integrated mode of seat 10 with first.
Further, owing to can be impacted by different directions in real work by traction apparatus, for
This, the buffer unit in the embodiment of the present invention also includes that buffering first fixes seat 10 (figure in a second direction
B direction shown in 1) the fork buffer gear of mobile impact, by the pendulum of fork buffer gear
Dynamic realization fixes seat 10 buffering in a second direction to first, and wherein, fork buffer gear is acted on
Second direction and the first direction that acted on of sliding sleeve buffer gear intersect, to realize different degree of freedom punching
The buffering hit.
As shown in figures 1 and 3, specifically, fork buffer gear includes fork 50, fork 50
First end is connected with sliding sleeve buffer gear, specifically at the first end and the sliding sleeve buffer gear of fork 50
Sleeve 40 connects, namely fork 50 is realized by the sleeve 40 in sliding sleeve buffer gear and slide bar 30
Fork 50 is rotatably connected the first end；Similarly, the second end at fork 50 arrange equally with
The tube-in-tube structure that first end is similar, realizes being rotatably connected by tube-in-tube structure, and fork 50
The rotary shaft of the second end is parallel with first direction, thus, the two ends of fork 50 in fork buffer gear
The most rotatable, it is to avoid the moment of torsion transmission that impact produces, it is also possible to avoid fork self to bear moment of flexure.Separately
Outward, coordinated by two rotary shafts, it is achieved first fixes seat 10 damping of shocks in a second direction.
Preferably, as shown in Figure 1 and Figure 4, for realizing further fixing seat 10 along multiple to first
The buffering effect in direction, buffer unit according to embodiments of the present invention also includes that buffering first fixes seat 10
Along the rotation buffer gear of the impact of third direction (the C direction shown in Fig. 1), wherein, the 3rd
Direction all intersects to realize different degree of freedom buffering from second direction and first direction.Preferably, first
Direction, second direction and third direction are vertical two-by-two, the most convenient processing and assembling, on the other hand
It is also easier to realize multiple degrees of freedom buffering.
Specifically, rotate buffer gear to include being rotationally connected bar 60.It is rotationally connected the first end of bar 60
It is rotationally connected with the tube-in-tube structure of fork 50 second end.It is rotationally connected second end and second of bar 60 admittedly
Reservation 20 is rotationally connected, and specifically fixes on seat 20 at the second end and second being rotationally connected bar 60
It is provided with hinge hole, rotary shaft realizes being rotationally connected second end and the of bar 60 through this hinge hole
Two fix seat 20 is rotationally connected, and the rotary shaft of the second end being rotationally connected bar 60 is parallel with second direction.
Owing to the direction of the rotary shaft of the first end and the second end that are rotationally connected bar 60 is different, it is achieved that rotate
The switching in direction, thus can obtain fix first seat 10 third direction rotation impact and move
The buffering of dynamic impact, improves buffering effect further, improves the life-span of traction apparatus.
Preferably, the coupling hitch in the embodiment of the present invention also includes detachable stop configurations, can
Dismounting stop configurations end face with the sleeve 40 in sliding sleeve buffer gear at restraining position abuts against joins
Close, to limit buffer unit buffer position in the first direction, simultaneously because detachable stop configurations can
With dismounting easily, hence for the fork 50 of easily appearance abrasion, in detachable stop configurations of dismantling
After, in that context it may be convenient to it is replaced.
Specifically, as in figure 2 it is shown, detachable stop configurations includes limit shaft, and at slide bar 30
The spacing hole 31 that upper corresponding restraining position is arranged, limit shaft is through this spacing hole 31 prominent and slide bar
The periphery of 30, abuts with the end face of sleeve 40 to limit buffer unit buffering position in the first direction
Put.
The present invention also provides for a kind of production line, and production line includes chassis, for drawing the traction dress of chassis
Putting, and connect chassis and the coupling hitch of traction apparatus, coupling hitch is above-mentioned each reality
Execute the coupling hitch in example.Thus the production line in the embodiment of the present invention is due to coupling hitch
To the buffering of the impact of the generation of chassis in production line, the feelings that traction apparatus stress is abnormal can be improved
Condition, the service life of lifting traction device.Wherein, the coupling hitch in the embodiment of the present invention can
Think conduction chain, by using the coupling hitch of the present invention, conduction chain can be effectively improved
Life-span.
