A kind of arrangements for automotive doors long limit edge covering mechanism
Technical field
The utility model relates to automobile component manufacture field, is particularly useful for arrangements for automotive doors long limit bound edge equipment.
Background technology
The long limit of existing arrangements for automotive doors (length is more than 1200mm) wrapping process mainly adopts two bound edge unit segmentation bound edges or adopts bound edge to drive oil cylinder to be placed in a middle bound edge unit and realizes.Adopt during two bound edge unit segmentation bound edges and can produce obvious seam in bound edge module joint; Adopt bound edge drive oil cylinder be placed in a middle bound edge unit to complete wrapping process then due in the middle part of module and pressure at two ends is uneven cause long limit bound edge after occur in the middle of the tight and phenomenon that two ends bound edge is unreal of bound edge.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the utility model provides a kind of edge covering mechanism being applicable to the long limit of arrangements for automotive doors, and solve the seam problems that existing bound edge exists, after making long limit bound edge, crest line is smooth-going, bound edge is tight, promotes the entrucking effect of bound edge of vehicle door cover assembly.
The utility model is by the following technical solutions: a kind of arrangements for automotive doors long limit edge covering mechanism, it is characterized in that: be made up of pre-bound edge unit and bound edge unit, wherein pre-bound edge unit comprises the pre-bag support connected by first connecting rod, pre-bag oil cylinder and pre-bag L plate, described pre-bag support and described pre-bag oil cylinder are positioned in the middle part of described first connecting rod, and described pre-bag L plate is equipped with pre-bound edge module; Bound edge unit comprises the first bound edge support, the second bound edge support, the first bound edge oil cylinder, the second bound edge oil cylinder and the bound edge L plate that are connected by second connecting rod, described first bound edge support and described first bound edge oil cylinder are positioned at the same one end of described second connecting rod, described second bound edge support and described second bound edge oil cylinder are positioned at the described second connecting rod other end, and described bound edge L plate is equipped with bound edge module.
Further, pre-bag oil cylinder, the first bound edge oil cylinder and the second bound edge oil cylinder are equipped with piston rod, wherein the piston rod of pre-bag oil cylinder connects described first connecting rod by its cylinder connector, and the first bound edge oil cylinder is connected described second connecting rod with the piston rod of the second bound edge oil cylinder by its cylinder connector.Such structure makes pre-bound edge module and the translation of bound edge module and non-rotating.
Further, the working face of pre-bound edge module and the angle of horizontal plane are 30 ° ~ 45 °.Be positioned at the position in the middle part of long limit, be convenient to whole long spring to be converted into certain angle.
Further, the first bound edge support and the second bound edge support are provided with the limited block limited described second connecting rod position, can adjust limited block in place, adapt to the long limit of different length.
Beneficial effect of the present utility model: allow the bound edge of automobile door cover longer sides not by module splicing, many actions impact of piecing together and become and do not have seam, after making longer sides bound edge, crest line is smooth-going, bound edge is tight, improve the quality of bound edge of vehicle door cover assembly, the movement locus of module becomes translation by rotation simultaneously, oil cylinder working-pressure is utilized more fully, decreases energy loss.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises pre-bound edge unit and bound edge unit, and wherein car door is first folded into certain angle by pre-bound edge unit, is generally 45 °, and flanging flattens by bound edge unit again, completes the bound edge treating hired car door.
Pre-bound edge unit of the present utility model comprises first connecting rod 3, pre-bag support 2, pre-bag oil cylinder 4 and pre-bag L plate 1, and pre-bag L plate is equipped with pre-bag module 12.Under pre-bag oil cylinder 4 drives, cylinder piston rod stretches out, and drives pre-bound edge module 12 to travel forward, wrapped in advance by car door flanging to 45 ° by the first connecting rod 3 be connected with cylinder connector 41, then cylinder piston rod is retracted, and pulls pre-bound edge module 12 to move backward and is retracted into initial position.Unlike the prior art, the utility model does not adopt rotating mechanism, and with parallel moving mechanism, can make full use of oil cylinder working-pressure.
After pre-bound edge completes, the the first bound edge oil cylinder 8 and the second bound edge oil cylinder 9 that are positioned at car door longer sides two ends start action, twin-tub synchronously stretches out at the control lower piston rod of synchronous valve, bound edge module 11 is driven to move downward by the second connecting rod be connected with cylinder connector 81,91, complete the wrapping process of car door longer sides, then the piston rod of twin-tub is synchronously retracted, and pulls bound edge module 11 to be retracted into initial position.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.
