Problems solved by technology

[0005] The method adopted in the above-mentioned prior art requires the AGV to have a lifting function. However, because the clamps are often heavy, the cost of the electric lifting device of the AGV is very high. In addition, the lifting process itself consumes a lot of electric energy, which requires additional power for the AGV powered by batteries. Add battery to ensure enough working time
Both of the above will increase the cost of equipment procurement, and will increase the energy consumption of AGV
In addition, in order to limit the excessive size of the AGV, the capacity of the lifting device on it is limited, and the lifting process is slow, which will cause prolonged positioning time of the fixture, slow down the beat of the station, and poor manufacturability

specific Embodiment approach

[0049] In order to clearly and completely describe the technical solution of the present invention and its specific working process, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:

[0050] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise specified limit. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

[0051] In the present i...

Embodiment 1

[0054] Such as figure 1 As shown, the first embodiment discloses a lifting and positioning mechanism for a flexible welding island fixture, including: a base, a lifting cylinder, a hinged head, a top plate, a guide post, a positioning assembly, a pneumatic slide rail, a connecting plate and a limit block.

[0055] The base 1 is fixedly installed on the ground as the base body of the entire lifting mechanism;

[0056] The lifting cylinder 2 is vertically arranged in the middle of the base 1, the cylinder end of the lifting cylinder 2 is fixed on the base 1, and the push-pull end of the lifting cylinder 2 is connected with the top plate 4 above by a hinged joint 3.

[0057] The top plate 4 is horizontally arranged directly above the base 1, and the middle part of the top plate 4 is connected with the lifting cylinder 2 through the hinge joint 3. The four corners of the top plate 4 are symmetrically fixed downwards and respectively fixed with four guide columns arranged in the ve...

Embodiment 2

[0083] Such as image 3 As shown, the second embodiment discloses an automatic switching device for flexible welding island clamps, including: a guide mechanism, a lift positioning mechanism, a clamp detection unit, a clamp identification unit and a medium unit.

[0084] There are two groups of the guide mechanism, respectively the first guide mechanism 100 and the second guide mechanism 200. The first guide mechanism 100 and the second guide mechanism 200 are arranged symmetrically in the left and right along the guide direction at the empty material opening, and fixed Installed on the ground, when the welding island needs a certain fixture 900, the AGV800 drags the fixture 900 to the designated empty material opening, and the guide wheels on the left and right sides of the fixture 900 first cooperate with the first guide mechanism 100 and the second guide mechanism on both sides 200 inside the guide surface contact, the first guide mechanism 100 and the second guide mechanis...

Abstract

The invention discloses a flexible welding island clamp positioning lifting mechanism, an automatic switching device and a switching method. In the positioning lifting mechanism, a lifting air cylinder is installed in the middle of a base; the push-pull end is connected with a top plate above; the bottom of the top plate is provided with a guide column matched with a guide hole in the base; a positioning assembly is fixed to the upper surface of the top plate; a pneumatic sliding rail is horizontally fixed to the upper surface of the base; the sliding end of the pneumatic sliding rail is connected with a limiting block; the limiting block is provided with two limiting faces with different heights; and under driving of the pneumatic sliding rail, the limiting block moves and switches the limiting faces with different heights to abut against the limiting contact face at the bottom of the top plate, limiting of the top plate at different height positions is achieved, and then a clamp is controlled to be positioned at different heights. The automatic switching device of the clamp is composed of a guide mechanism, a lifting positioning mechanism, a clamp detection unit, a clamp recognition unit and a medium unit. Automatic switching of the clamp can be achieved, the equipment purchasing and using cost is reduced, and the switching time is shortened.

Description

technical field [0001] The invention belongs to the technical field of flexible welding island fixture positioning and switching, and in particular relates to a flexible welding island fixture positioning and lifting mechanism, an automatic switching device and a switching method. Background technique [0002] With the gradual rise of customization in the automobile consumer market, automobile manufacturers are increasingly emphasizing the flexibility of production lines. This is especially true in the body manufacturing industry with a high level of automation, and the concept of island-type production welding unit (hereinafter referred to as welding island) came into being. [0003] The transfer of materials, tools or tooling between islands is realized by AGV (Automatic Guided Vehicle), and the level of intelligence has been significantly improved. The flexibility of the production unit is limited by factors such as different material forms and different fixtures and too...
