Rotatable cylinder connecting device

Abstract

The invention discloses a rotatable cylinder connecting device which is fixedly arranged on an equipment platform. The device comprises an intermediate shaft, a pneumatic joint mechanism and a transmission connection mechanism, wherein the pneumatic joint mechanism and the transmission connection mechanism are overlapped from top to bottom; the intermediate shaft is rotatably arranged into the pneumatic joint mechanism and the transmission connection mechanism in a penetrating manner; the lower end of the intermediate shaft extends out of the transmission connection mechanism and is connectedto a driving motor, and the upper end of the intermediate shaft extends out of the pneumatic joint mechanism and is connected to a clamp tool. The device integrates the pneumatic connecting function and the transmission function; outside equipment is capable of continuously supplying gas and normally works through the pneumatic connection function; the problems of extremely easy shaking and loosening of an existing device can be avoided, and the overall stability of the device can be ensured through the transmission function.

Description

technical field [0001] The invention relates to a cylinder connection device, in particular to a rotatable cylinder connection device used on machining equipment, and belongs to the field of automatic processing. Background technique [0002] In recent years, with the rapid development and rapid rise of my country's manufacturing industry, my country's industrial production level has been significantly improved. Under such a background, the automobile processing industry, as an important part of industrial production, has also made great progress in its technical level and processing efficiency. [0003] Specifically, take the common flywheel processing in the automobile processing industry as an example. The flywheel is a disc-shaped part with a large moment of inertia, and it is also one of the parts that are used in major components such as automobile engines and gearboxes. At present, the shape, specification and deviation value requirements of the flywheel discs used b...

Problems solved by technology

In the prior art, the jaws of the three-jaw cylinder and the cylinder are generally connected by means of communication pipelines, but under such working conditions, the jaws of the three-jaw cylinder need to be driven together with the rotation of the drive motor. Rotate and complete the clamping of the flywheel disc. If you still use the current common way of connecting pipelines to connect, it is easy to cause the connecting pipelines to be entangled and knotted due to rotation, which will affect the overall use of the equipment.

[0006] In addition, in the process of connecting the drive motor with the three-jaw cylinder and the load-carrying mechanism, a transmission shaft is also required. Currently, the common transmission shafts on the market have disadvantages due to their own structure, and they are subjected to severe stress during use. Due to the influence of radial force and axial force, it is very easy to shake, loose, etc., with poor stability and low durability
