Description

A hinge connection method and its connection mechanism

technical field

The invention relates to a hinge point connection method and a connection mechanism thereof.

Background technique

With the development of industry, more and more mechanisms are applied to mechanical equipment. The traditional hinge point only has relative rotational movement, while the hinge point that needs translation and rotation is the pin shaft directly matched with the oblong hole, and its contact area is small and cannot be used. Under heavy load conditions, and heavy load conditions require the combination of the two mechanisms to achieve. How to use a simple hinge point connection method to realize translation and rotation connection under heavy load is a technical problem to be solved by those skilled in the art.

Contents of the invention

Aiming at the shortcomings of the above-mentioned prior art, the present invention provides a hinge point connection method and its connection mechanism, which can realize the compound hinge point connection of translation and rotation under heavy load conditions.

In order to achieve the above object, a hinge connection mechanism of the present invention includes a double ear structure, a single ear structure, a shaft sleeve and a pin shaft, and the single ear structure is provided with an oblong hole, and the long diameter of the oblong hole is along the length of the single ear. The width direction of the structural part is set, the pin shaft is fixedly connected with the double lug structural part, and the bushing set in the oblong hole is connected with the pin shaft in rotation. The shape of the bushing is oblong, and the short diameter of the bushing corresponds to the short diameter of the long round hole. The major diameter of the sleeve is smaller than the major diameter of the oblong hole, and the shaft sleeve can slide along the major diameter direction of the oblong hole.

The shaft sleeve is a copper shaft sleeve; the copper shaft sleeve has low hardness and has a self-lubricating function.

Another problem to be solved by the present invention is to provide a hinge point connection method. The technical solution is: a hinge point connection method includes that the connected double ear structure and single ear structure can be rotated relatively, or along their width Directional relative translational motion, or a combination of the above two motions.

Beneficial Effects of the Invention

The double-ear structural member and the single-ear structural member of the present invention can be relatively translated or rotated relatively, and at the same time, the oblong shaft sleeve, the pin shaft, and the single-ear structural member are in large-surface contact, which can effectively reduce the contact stress and ensure that the two structures The relative movement of parts is safe and reliable. The invention has few components, simple structure, convenient use, and can realize relative translation and rotation under heavy load.

Detailed ways

As shown in the figure, a hinge point connection mechanism includes a double-ear structural member 1, a single-ear structural member 2, a bushing 3 and a pin shaft 4, and the single-ear structural member 2 is provided with an oblong hole 6, and the length of the oblong hole 6 is The diameter is set along the width direction of the single-ear structural member 2, the pin shaft 4 is fixedly connected with the double-ear structural member 1 by screws 5, the inner hole of the shaft sleeve 3 arranged in the oblong hole 6 is rotatably matched with the pin shaft 4, and the shape of the shaft sleeve 3 It is oblong, and the short diameter direction corresponds to the short diameter of the oblong hole 6. The long diameter of the bushing 3 is smaller than the long diameter of the long round hole 6, and the bushing 3 can slide along the long diameter direction of the long round hole 6. The shaft sleeve 3 is a copper shaft sleeve with low hardness and self-lubricating function, which is replaced after wear and tear. The binaural structural member 1 and the monaural structural member 2 can translate or rotate relative to each other. A hinge point connection method is that the connected double-ear structure 1 and single-ear structure 2 are relatively rotated, or relatively translated along their width direction, or a combination of rotation and translation.
