Description

A kind of quadric chain
Technical field
This utility model relates to technical field of automation equipment, particularly to a kind of quadric chain.
Background technology
Assemble field at vehicle, be frequently encountered by and need to be fitted in cutting ferrule 1, with reference to attached accessory 3 to be installed Fig. 1, accessory 3 to be installed needs one end to be introduced in pilot hole 2, and the other end enters with the movement locus of arc again Another pilot hole 2, existing automation equipment is difficult to accomplish by accessory 3 to be installed with the movement locus of arc Carry out transporting assembling, so the existing mode of production is all to use to install manually, such operator Labor intensity the highest, easily product is produced and damages thus cause waste, and production efficiency is the lowest. Therefore, how to design and a kind of accessory 3 to be installed just can be assembled to the scheme in cutting ferrule 1 with arc track It it is the present inventor's problem to be solved.
Utility model content
The deficiency existed for prior art, main purpose of the present utility model is to provide the one can be by Accessory to be installed carries out the quadric chain transported with arc track.
For achieving the above object, this utility model provides following technical scheme: a kind of quadric chain, Including fixed pedestal and tool, described fixed pedestal is hingedly connected with first connecting rod and second connecting rod, institute Stating first connecting rod and be positioned at below second connecting rod, described first connecting rod is relatively fixed the hinged company of the other end of pedestal Being connected to third connecting rod, described first connecting rod is also hingedly connected with fourth link, described second connecting rod and the 4th Rod hinge connection, on described third connecting rod and fourth link, the other end relative to first connecting rod is all articulated and connected On tool, the other end that described second connecting rod is relatively fixed pedestal is hinged with third connecting rod, described tool Including the placing trough for placing accessory to be installed, the lower section of described fixed pedestal is provided with draft cylinder, institute Stating draft cylinder to be fixedly connected with cylinder and fix seat, described draft cylinder includes piston rod, described piston rod Connecting has fixed block, described fixed block to be articulated and connected with the end of first connecting rod and third connecting rod.
Preferably, the shape, big of described first connecting rod, second connecting rod, third connecting rod and fourth link Little the most identical.
This utility model has the advantage that relative to prior art, draft cylinder action, and piston rod stretches out, And drive first connecting rod to rotate up centered by fixed pedestal by fixed block, third connecting rod and the simultaneously Double leval jib moves upward, and the movement travel of third connecting rod is more than the movement travel of fourth link, so Also make the tool with the third and fourth rod hinge connection can carry out ascending motion with the track of an arc, its Middle fourth link plays the effect of stable connection, and tool is provided with placing trough, as long as being put by band assembly parts Can realize transporting accessory to be installed with arching trajectory in placing trough, the automatization that can first assemble, energy Enough improve product yield, reduce the waste of manpower and improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the technology requirement of prior art;
Fig. 2 is the structural representation of a kind of quadric chain of the present utility model;
Fig. 3 is the front view of a kind of quadric chain of the present utility model.
In figure: 1, cutting ferrule;2, pilot hole;3, accessory to be installed;4, fixed pedestal;5, first connecting rod; 6, second connecting rod;7, third connecting rod;8, fourth link;9, tool;10, placing trough;11, draw Stretch cylinder;12, cylinder fixes seat;13, piston rod;14, fixed block.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 2 to Figure 3, a kind of quadric chain, including fixed pedestal 4 and tool 9, fixed base Being hingedly connected with first connecting rod 5 and second connecting rod 6 on seat 4, first connecting rod 5 is positioned at below second connecting rod 6, First connecting rod 5 is relatively fixed the other end of pedestal 4 and is hingedly connected with third connecting rod 7, and first connecting rod 5 also cuts with scissors Being connected to fourth link 8 in succession, second connecting rod 6 is hinged with fourth link 8, and third connecting rod 7 and the 4th connects All being hingedly connected on tool 9 relative to the other end of first connecting rod 5 on bar 8, second connecting rod 6 is the most solid The other end determining pedestal 4 is hinged with third connecting rod 7, and tool 9 includes the placement for placing accessory to be installed Groove 10, the lower section of fixed pedestal 4 is provided with draft cylinder 11, and draft cylinder 11 is fixedly connected with cylinder Fixing seat 12, draft cylinder 11 includes that piston rod 13, piston rod 13 connect with first connecting rod 5 and the 3rd The end of bar 7 is articulated and connected.
With reference to Fig. 2 and Fig. 3, the operation principle of quadric chain of the present utility model is, draft cylinder 11 Action, piston rod 13 stretches out, and drives during first connecting rod 5 with fixed pedestal 4 is by fixed block 14 The heart rotates up, and third connecting rod 7 and fourth link 8 move upward simultaneously, and the fortune of third connecting rod 7 Dynamic stroke, more than the movement travel of fourth link 8, the most also makes hinged with the third and fourth connecting rod 8 Tool 9 can carry out ascending motion with the track of an arc, and wherein fourth link 8 plays stable connection Effect, tool 9 is provided with placing trough 10, as long as band assembly parts are put in placing trough 10 and can be realized Accessory to be installed is transported with arching trajectory, the automatization that can first assemble, it is possible to increase product yield, subtract The waste of few manpower and raising production efficiency.
Further, first connecting rod 5, second connecting rod 6, third connecting rod 7 and the shape of fourth link 8, Size is the most identical.The benefit so arranged is when occurring in which that a connecting rod damages, in that context it may be convenient to make With the spare parts of other connecting rod, covert reduces maintenance cost.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not Being limited only to above-described embodiment, it is new that all technical schemes belonged under this utility model thinking belong to this practicality The protection domain of type.It should be pointed out that, for those skilled in the art, without departing from Some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as this practicality Novel protection domain.
