Description

Floating support device with automatic centering function Technical Field The present invention relates to a centering device, and more particularly, to a floating support device with automatic centering. Background The floating centering device is applied to various production lines and is used for carrying out floating positioning after centering operation on accessories so as to complete assembly of the accessories, and the existing floating centering device has the following defects: 1. The equipment is often provided with a middle clamp assembly and a lifting mechanism, and the middle clamp assembly and the lifting mechanism are required to be driven to lift by two driving sources, so that the mechanism is complex, and the problems of complex maintenance and synchronous debugging are caused; 2. The presence of a plurality of long travel rails in the device can result in a substantial increase in footprint, as well as substantial increases in device material costs and maintenance costs. Accordingly, in view of the above-mentioned problems, there is a need to develop a floating centering device that can maintain the efficiency of the device and greatly reduce the complexity and cost of the device. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide the floating support device with the automatic centering function, which has the advantages of simple structure, low cost and convenient adjustment. In order to achieve the aim, the invention provides the technical scheme that the floating support device with the automatic centering comprises a lifting frame, a pull block assembly, a centering clamp assembly and a lifting cylinder; The centering clamp assembly is arranged on the lifting frame, one end of the lifting frame is provided with a main frame hinging seat, and the other end of the lifting frame is provided with a floating supporting wheel; the lifting cylinder is connected with the lifting frame and is used for pushing the lifting frame to turn over along the hinge seat of the main frame; The pull block assembly comprises a guide rail, an installation seat and a limit strip, wherein the installation seat is connected to the guide rail in a sliding manner, a plurality of installation holes are formed in the installation seat, and the limit strip is fixedly installed on the installation seat through the installation holes and is obliquely arranged; And a limiting wheel which is used for abutting against the limiting strip is arranged on one side of the lifting frame, which is close to the mounting seat. In summary, the application has the advantages that when the lifting cylinder stretches out, the cylinder enables the lifting frame to rotate anticlockwise, so that the floating supporting wheel is lifted until the limiting wheel positioned at the side is tangent to the limiting bar, at the moment, the lifting process is stopped, the turnover degree of the lifting frame is controlled by the position of the limiting bar on the pull block assembly, and the mechanism is simplified, and as the centering clamp assembly synchronously turns along with the lifting mechanism, the lifting mechanism of the original centering clamp assembly can be removed, and only the centering function is reserved; the cost is reduced, except the wired rail in the pull block assembly, the rest parts do not have long-stroke wired rails, and the cost is effectively reduced.
