Description

Balance weight mechanism

Technical Field

The utility model belongs to the technical field of glass processing, especially, relate to a balance weight mechanism

Background

In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:

in the glass processing equipment, in the swinging process of the swinging rod, a balancing weight needs to be arranged for matching, the weight of the swinging rod is 10kg, and the weight of the balancing weight is 12.8kg according to the calculation of the force arm. Because of the size of the restriction balancing weight in space, according to calculation needs 8 counter weight plates, install respectively in the both sides of swing arm to still need to adjust the counter weight according to in-service use. The structure is complicated, and the occupied space is large.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a more convenient balanced counter weight mechanism of big or small adjustment of counter weight is provided to a structure is simpler.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a balance weight mechanism having:

a rotating shaft;

a swing arm, the first end of which is rotatably arranged on the rotating shaft;

the swing rod is hinged with the second end of the swing arm and can pull the swing arm to rotate around the rotating shaft;

a spring balancer coupled proximate the second end of the swing arm.

The swing arm is rotatably arranged on the rotating shaft through a bearing; the rotating shaft is installed on the rack through a bearing seat.

The spring balancer is mounted on the mounting seat, and the mounting seat is mounted on the frame.

And the swing arm is also provided with a series of lightening holes.

One of the technical scheme has the advantages or beneficial effects of simpler structure, small occupied space and more convenient size adjustment of the counterweight.

Drawings

Fig. 1 is a schematic structural view of a balance weight mechanism provided in an embodiment of the present invention;

the labels in the above figures are: 1. the device comprises a rotating shaft, 2, a swing arm, 3, a bearing seat, 4, a swing rod, 5, a spring balancer, 6 and a mounting seat.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a balance weight mechanism has:

a rotating shaft 1; a swing arm 2, a first end of which is rotatably arranged on the rotating shaft 1; the swing rod 4 is hinged with the second end of the swing arm 2, and the swing rod 4 can pull the swing arm 2 to rotate around the rotating shaft 1; and a spring balancer 5 connected to the vicinity of the second end of the swing arm 2. The balance weight is cancelled, the balance weight is changed into a spring balancer 5, and the pulling force (9kg-15kg) of the spring balancer is adjustable.

The swing arm 2 is rotatably arranged on the rotating shaft 1 through a bearing; the rotating shaft 1 is mounted on the frame by means of a bearing block 3.

The spring balancer is characterized by further comprising a mounting seat 6, the spring balancer 5 is mounted on the mounting seat 6, and the mounting seat 6 is mounted on the rack and is convenient to mount.

A series of lightening holes are further formed in the swing arm 2 to achieve the lightening effect.

After adopting foretell structure, the structure is simpler, and occupation space is little, and the size adjustment of counter weight is more convenient.

In the description of the present invention, it is to be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "one side", "top", "inner", "front", "center", "both ends", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "disposed," "connected," "fixed," "screwed" and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
