Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
A jaw apparatus as shown in figure 1 for gripping an article. In fig. 1, a is used to connect the rotating mechanism or the boom arm so that the entire gripper apparatus can be rotated or moved.
The clamping jaw device comprises a fixing plate 1, a first clamping jaw 7 arranged on the fixing plate 1 in a sliding mode and a second clamping jaw 8 arranged on the fixing plate 1 in a sliding mode. The first jaw 7 and the second jaw 8 define a clamping space therebetween, in which an article to be gripped is placed and clamped. The relative movement of the first jaw 7 and the second jaw 8 enables the gripping and release of the article. The opposite side of the first clamping jaw 7 and the second clamping jaw 8 is also provided with an anti-falling strip 11 for preventing the gripped object from falling.
Referring to fig. 2 and 2, which are another view of fig. 1, two guide rails 2 are provided on the lower surface of the fixing plate 1. The first jaw 7 is slidably arranged on the two rails 2 to slide smoothly in a strict direction. In order to facilitate the installation, a sliding block 12 is arranged on the first clamping jaw 7, and the sliding block 12 is arranged on the guide rail 2 in a sliding manner. The second jaw 8 is also slidably arranged on the two rails 2 to slide smoothly in a strict direction. Also, for the convenience of installation, a sliding block 12 is arranged on the second clamping jaw 8, and the sliding block 12 is arranged on the guide rail 2 in a sliding manner. Of course, only one rail 2 may be provided, and providing two rails 2 may allow the first jaw 7 and the second jaw 8 to slide more smoothly.
As shown in fig. 2, a motor 3 is disposed above the fixing plate 1, an output end of the motor 3 downwardly penetrates through the fixing plate 1, and an output end of the motor 3 is provided with a driving wheel 4. A driven wheel 5 is also arranged below the fixed plate 1. The driven pulley 5 is provided corresponding to the driving pulley 4.
A transmission belt 6 is arranged between the driving wheel 4 and the driven wheel 5. The transmission belt 6 is of a closed loop structure, and the transmission belt 6 is sleeved on the driving wheel 4 and the driven wheel 5 at the same time and used for transmission between the driving wheel 4 and the driven wheel 5. Thus, when the motor 3 drives the driving wheel 4 to rotate, the driven wheel 5 is driven to rotate through the action of the driving belt 6. The driven pulley 5 is arranged to provide support for the drive belt 6 so that the drive belt 6 can perform a closed loop rotational movement supported by the drive pulley 4 and the driven pulley 5. The opposite side portions of the belt 6 are oppositely moved.
In order to increase the friction between the driving wheel 4 and the drive belt 6, ribs 10 are provided on the periphery of the driving wheel 4 (see fig. 3). In order to increase the friction between the driven pulley 5 and the drive belt 6, ribs 10 are also provided on the outer periphery of the driven pulley 5 (see fig. 3).
As shown in fig. 4, one slider 12 of the first jaw 7 is connected to one side of the belt 6, and one slider 12 of the second jaw 8 is connected to the other side of the belt 6. In this way, when the belt 6 rotates in a closed loop, the first clamping jaw 7 and the second clamping jaw 8 can move closer to or away from each other in a centering manner, in short, the relative movement is always performed in a centering manner, and only one power source, namely, one motor 3 is used as a power source.
In order to control the stroke of the first jaw 7 and the second jaw 8, a sensing mechanism 9 is also provided.
As shown in fig. 3, fig. 3 is an enlarged view of fig. 2B, and the sensing mechanism 9 includes a shutter 91, an origin photosensor 92, a first extreme position sensor 93, and a second extreme position sensor 94.
The baffle 91 is attached to a slide 12, the baffle 91 also being attached to the belt 6. The first extreme position sensor 93, the origin photosensor 92, and the second extreme position sensor 94 are disposed in this order in the moving path of the shutter 91. Wherein a first extreme position sensor 93 and a second extreme position sensor 94 are arranged at extreme positions at both ends for controlling the maximum stroke of the shutter 91. The origin photosensor 92 is disposed between the first extreme position sensor 93 and the second extreme position sensor 94. Origin photoelectric sensor 92 is calibrated as the origin so that the stroke of baffle 91, and thus the stroke of first clamping jaw 7 and second clamping jaw 8, can be controlled.
The sensing mechanism 9 (including the included controls) is of a construction known in the art, but is not conventional for use with a jaw apparatus.
In summary, in the jaw apparatus of this embodiment, the first jaw 7 and the second jaw 8 are always relatively close to or relatively far away from each other in a centering manner by the action of the motor 3, the driving wheel 4, the driven wheel 5 and the transmission belt 6. And the stroke of the first clamping jaw 7 and the second clamping jaw 8 is controlled through the action of a sensing mechanism 9. And the maximum strokes of the first clamping jaw 7 and the second clamping jaw 8 are controlled through the first extreme position sensor 93 and the second extreme position sensor 94, so that the safety is improved.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
