Description

Dual-drive four-connecting-rod self-locking swing mechanism

Technical Field

The invention relates to a self-locking swing mechanism, in particular to a dual-drive four-connecting-rod self-locking swing mechanism, and belongs to the technical field of mechanical tool equipment.

Background

With the rapid development of the automobile industry, the brands and the types of automobiles are more and more, the body structures of the brands are different, and especially, the special structures of some positions can provide non-conventional process requirements for production equipment.

In the implementation of a new model of AUDI production line project, the nesting mode of old production line parts is sliding table type nesting. Because the structure of the vehicle body of the new vehicle type is changed more, the product has a plurality of wrap angles in the structure. The process also increases a lot of gluing requirements. The original sliding table type sleeve structure is required to meet the process requirements, and the sliding table type sleeve structure is large in mechanism design, occupies more station space and is difficult to meet the operation requirements of man-machines. Moreover, the parts of the mechanism are also in conversion connection at a plurality of angles in design, so that the manufacturing difficulty of the parts of the mechanism is increased. In view of this, a dual-drive four-bar self-locking swing mechanism is urgently needed in the industry.

Disclosure of Invention

In order to solve the problems, the invention provides a dual-drive four-connecting-rod self-locking swing mechanism (namely, a swing type sleeving mode is used for replacing the original mode) through the analysis of a vehicle body product, so that the problems of more product structure wrap angles and easy interference in the movement process can be easily avoided, the glue which is coated on parts in advance can not be scraped, and the mechanical structure can be greatly simplified.

The invention is realized by adopting the following technical scheme:

a dual-drive four-bar self-locking swing mechanism comprises: swing support body 1 and four-bar linkage swing mechanism 2, wherein swing support body 1 connecting plate 106 passes through bolted connection with swing seat 209 in the four-bar linkage swing mechanism 2, in operation, when extreme position as in fig. 1, lean on the auto-lock nature auto-lock of four-bar linkage swing mechanism 2, at this moment swing support body 1 keeps the level, fix the automobile body on the location clamping workpiece on swing support body 1 again, when needing to swing, outwards extend through cylinder 201, drive swing seat 209 and rocker II 212 around the axle on the fixing base 213 clockwise, realize the swing of automobile body angle, the effect of buffer 203, stopper 204 and stopper I207 is to prevent to swing too big and cause the damage to automobile body and equipment.

From the safety point of structural use, a 4-link structure which can realize self-locking mechanically is selected in advance. When the mechanism is at the position shown in fig. 1, the mechanism is also at the limit position, the rocker lever ii 212, the connecting rod 208, the rocker lever 205 and the base 201 form a four-bar mechanism, referring to the diagram of fig. 4, the rocker lever 205 is connected with the cylinder 202 to be a driving part, the rocker lever ii 212 is a driven part, as the connecting rod 208 and the rocker lever 205 are on the same straight line, an external force is applied to the rocker lever ii 212 (the driven part), and as the connecting rod 208 and the rocker lever 205 (the driving part) are on the same straight line, the line of action of the force passes through a turning point, so that the moment arm is equal to zero, and no effective moment is generated to realize self-locking.

The beneficial effects of the invention are as follows: the structure is simple, the operation is convenient, and the stability and the safety of the system are improved to the maximum extent while the special requirements of the production process are met.
