Abstract
The utility model discloses a connection pair of a mechanical arm. The connection pair of the mechanical arm comprises a first connecting arm, a second connecting arm and a connecting pin, and further comprises a connecting cylinder. An end of the first connecting arm is provided with a first connecting cylinder, an end of the second connecting arm is provided with a U-shaped link fork, and two ends of the U-shaped link fork are provided with two second connecting cylinders. The connecting cylinder is respectively connected with the first connecting cylinder and the second connecting cylinders, and the connecting pin is connected with the connecting cylinder. The connection pair of the mechanical arm has the advantages of being simple and reliable in structure, high in transmission efficiency and accuracy, long in service life, and low in cost.
Description
Technical field
The utility model relates to a kind of auxiliary connection, more precisely is a kind of mechanical arm auxiliary connection.
Background technique
Usually need use auxiliary connection to connect two mechanical arms in the machinery, but auxiliary connection of the prior art only uses connecting pin, connecting pin is prone to be worn, and influences the working life and the precision of auxiliary connection, and the transmission efficiency of auxiliary connection of the prior art is lower simultaneously.
Summary of the invention
The utility model mainly is to solve the existing in prior technology technical problem, thereby provides a kind of simple and reliable for structure, and transmission efficiency and precision are higher, long service life, lower-cost mechanical arm auxiliary connection.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of mechanical arm auxiliary connection; Comprise one first link arm, one second link arm and a connecting pin, described auxiliary connection also comprises a connecting cylinder, and the end of described first link arm is provided with one first and connects tube; The end of described second link arm is provided with a U type clevis; The end of described U type clevis is provided with two second and connects tube, and described connecting cylinder and described first connects tube and the described second connection tube is connected, and described connecting pin is connected with described connecting cylinder.
As the utility model preferred embodiment, described two second spacings that connect between the tube equal described first connect tube height, described first connects that a tube internal diameter, described second connects the internal diameter of tube and the external diameter of described connecting cylinder equates.
As the utility model preferred embodiment, the internal diameter of described connecting cylinder equates that with the external diameter of described connecting pin described connecting pin is fixedly connected through fixing pin with described connecting cylinder.
Therefore the advantage of the mechanical arm auxiliary connection of the utility model is, simple and reliable for structure, transmission efficiency and precision are higher, long service life, and cost is lower.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the mechanical arm auxiliary connection of the utility model;
Fig. 2 is the blast structural representation of the auxiliary connection among Fig. 1;
Wherein:
1, first link arm; 11, first connects tube;
2, second link arm; 21, U type clevis; 22, second connects tube;
3, connecting cylinder; 4, connecting pin.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
It is a kind of simple and reliable for structure that the utility model provides, and transmission efficiency and precision are higher, long service life, lower-cost mechanical arm auxiliary connection.
Like Fig. 1, shown in Figure 2, a kind of mechanical arm auxiliary connection comprises one first link arm 1, one second link arm 2 and a connecting pin 4; This auxiliary connection also comprises a connecting cylinder 3; The end of this first link arm 1 is provided with one first and connects tube 11, and the end of this second link arm 2 is provided with a U type clevis 21, and the end of this U type clevis 21 is provided with two second and connects tube 22; This connecting cylinder 3 is connected with this first connection tube 11 and this second connection tube 22, and this connecting pin 4 is connected with this connecting cylinder 3.
These two second spacings that connect between the tube 22 equal this first connect tube 11 height, this first connects tube 11 internal diameters, this second connects the internal diameter of tube 22 and the external diameter of this connecting cylinder 3 equates.
The internal diameter of this connecting cylinder 3 equates with the external diameter of this connecting pin 4, and this connecting pin 4 and this connecting cylinder 3 are fixedly connected through fixing pin.
The mentality of designing of the utility model below only is described with a mode of execution, and under the situation that system allows, the utility model can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
