Description

Technical Field

[0001] The utility model relates to the technical field of cylinders, in particular to a quick installation structure for a cylinder tail seat. Background Art

[0002] At present, the cylinders of the existing technology are actuators that convert hydraulic energy or pneumatic energy into mechanical energy and perform linear reciprocating motion (or swinging motion). According to the required motion trajectory on different devices, the bottom of the cylinder is fixed or the tail of the cylinder is hinged. Usually, when hinging with the tail end of the cylinder, an articulated tail seat needs to be installed at the tail end of the cylinder to be connected with other connecting parts (external articulated seat), and the external articulated seat and the articulated tail seat are generally articulated through a pin shaft.

[0003] However, in the existing technology, whether it is the articulated seat at the tail end or the head end of the cylinder, after being articulated with the external articulated seat, the connection part belongs to a rigid hinge. Such a hinging method is likely to cause wear at the connection part, affecting the normal use of the cylinder. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a quick installation structure for a cylinder tail seat, which can effectively solve the problem that "the hinge joints at the head end or tail end of the cylinder are prone to wear due to rigid hinge joints".

[0005] To solve the above technical problem, the technical solution provided by the utility model is as follows:

[0006] A quick installation structure for a cylinder tail seat includes a cylinder, and also includes a cylinder articulated tail seat, a cylinder articulated head seat, an external articulated seat, a pin shaft and a bearing; the cylinder articulated tail seat is fixedly installed at the tail end of the cylinder, the piston shaft end is fixedly installed with a cylinder articulated head seat, there are two external articulated seats, and they are respectively articulated with the cylinder articulated tail seat and the cylinder articulated head seat through a pin shaft, and the external articulated seat and the pin shaft are connected through a bearing.

[0007] As an improvement, the cylinder articulated tail seat has a structure in which a pair of ear plates I are formed on the articulated side of a flat plate I, and the ear holes on the two ear plates I are of different sizes;

[0008] The external articulated seat has a structure in which an ear plate II is formed on the articulated side of a flat plate II;

[0009] The pin shaft is a T-shaped cylinder, and after the thick section is nested in an ear plate I and the inner side of the ear plate II at the same time, the thin section is nested in the inner side of the other ear plate I, and after the step surface of the pin shaft fits with the corresponding ear plate I, the pin shaft is fixed on the cylinder articulated tail seat through a lock nut sleeved on the thin section by a thread.

[0010] As an improvement, the cylinder articulated head seat is a U-shaped plate body structure, and the ear holes of different sizes are formed at both ends;

[0011] The structure in which the cylinder hinge joint seat and the externally mounted hinge seat are hinged by a pin shaft is the same as the structure in which the externally mounted hinge seat and the cylinder hinge tail seat are hinged by a pin shaft.

[0012] As an improvement, a gasket is provided between the lock nut and the cylinder hinge tail seat or the cylinder hinge joint seat.

[0013] As an improvement, a knurled structure is formed on the outer circumferential wall of the thick section of the pin shaft, and the thick section is in interference fit with the ear hole of the corresponding ear plate 1 or an ear plate of the cylinder hinge joint seat.

[0014] The advantages of the present utility model compared with the prior art are as follows:

[0015] When the present utility model is in use, whether the cylinder hinge tail seat is connected to the externally mounted hinge seat or the cylinder hinge joint seat is connected to the externally mounted hinge seat, wear is not likely to occur at the connection, because the externally mounted hinge seat and the pin shaft are connected by a bearing, so that the problem of "easy wear at the hinge connection at the head end or tail end of the cylinder due to rigid hinge connection" can be effectively solved, and the installation operation of the cylinder is very convenient.
