Abstract
The invention relates to a mechanical arm. The mechanical arm comprises two support plates which are arranged in parallel and two side plates, one or both of the support plates are provided with openings so that the weight of the support plates can be reduced, multiple crossbeams and stand columns perpendicular to the crossbeams are arranged in the mechanical arm, the crossbeams are connected with the two side plates, and the stand columns are connected with the two support plates so that the structural strength of the two support plates in the direction perpendicular to the support plates can be reinforced.
Description
Technical field
The present invention relates to a kind of connecting rod, refer to a kind of mechanical arm being used as connecting rod especially.
Background technology
Along with the development of technology, manipulator due to the application in the industry of its automation, high efficiency more and more extensive.Because the stationarity of action when the rigidity of mechanical arm directly has influence on manipulator grabbing workpiece and positioning precision.As poor rigidity then can cause side direction torsional deflection in the flexural deformation of mechanical arm in vertical plane and horizontal plane, mechanical arm will produce vibration, or during action, workpiece is stuck cannot work.So manipulator is very high to the rigid requirements of its arm.In prior art, the arm of manipulator is in order to ensure the single piece type plate body that its rigidity adopts weight larger usually, but the weight of mechanical arm causes more greatly its operating rate to slow down, and inertia increases, and affects production efficiency.
Summary of the invention
In view of above content, be necessary provide a kind of weight to reduce but do not affect the mechanical arm of rigidity.
A kind of mechanical arm, comprise two gripper shoe be arranged in parallel and biside plates, one of them gripper shoe is provided with opening to alleviate the weight of described gripper shoe, some crossbeams and some columns perpendicular to described crossbeam is provided with in described mechanical arm, described crossbeam connects biside plate, and described column connects two gripper shoes to strengthen described two gripper shoes along the structural strength on vertical described gripper shoe direction.
Preferably, described side plate and described gripper shoe surround a space, and described crossbeam and described column are positioned at described interior volume.
Preferably, the cross section of described mechanical arm is rectangle.
Preferably, described mechanical arm is hollow strip.
Preferably, each gripper shoe is provided with an opening, and described crossbeam is between two openings.
Preferably, described crossbeam is parallel to described gripper shoe.
Preferably, described crossbeam comprises multiple, and the projection join line of described multiple crossbeam on wherein side plate is a straight line, and described straight line overlaps with the center line of described side plate.
Preferably, described column is positioned at described open at one end.
Preferably, described opening is circle, rectangle or triangle.
Compared to prior art, the gripper shoe of described mechanical arm is provided with opening to alleviate the weight of described mechanical arm, and described mechanical arm also comprises column and crossbeam to strengthen the rigidity of described mechanical arm.

Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Refer to Fig. 1 and Fig. 2, in a preferred embodiment of the present invention, a kind of mechanical arm 10 plays a part connect and bear external force in a manipulator.Described mechanical arm 10 is hollow strip.Described mechanical arm 10 comprises biside plate 12, two gripper shoe 14, at least one column 18 and at least one crossbeam 19.Described biside plate 12 and described two gripper shoes 14 are parallel to each other respectively.Described biside plate 12 is positioned at the both sides of described two gripper shoes 14 and connects described two gripper shoes 14 respectively, and described side plate 12 and described gripper shoe 14 surround a space 16.The cross section of described mechanical arm 10 is rectangle.Described side plate 12 is perpendicular to described gripper shoe 14.
Described gripper shoe 14 is provided with opening 142 and two connecting portions 144, and described opening 142 is between described two connecting portions 144.Described opening 142 can be the various shapes such as circle, rectangle, triangle.Opening 142 described in the present embodiment is rectangle.The weight that described opening 142 makes described mechanical arm 10 alleviate is greater than the weight that described crossbeam 19 and described column 18 make described mechanical arm 10 increase.Described crossbeam 19 two ends are connected with described biside plate 12, and described crossbeam 19 is parallel with described gripper shoe 14.Described crossbeam 19 is between described two openings 142, and the projection join line of described crossbeam 19 on wherein side plate 12 is a straight line and overlaps with the center line of described side plate 12.Described column 18 two ends are connected with described two gripper shoes 14, and described column 18 is perpendicular to described gripper shoe 14.Described column 18 is positioned at described opening 142 one end.Described column 18 and described crossbeam 19 are contained in described space 16.
Please continue to refer to Fig. 3, when using described mechanical arm 10, described two connecting portions 144 are connected with a fixed part and an operating portion respectively.Described mechanical arm 10 is connected one end and is subject to External Force Acting and makes described mechanical arm 10 produce displacement perpendicular to described gripper shoe 14 with described operating portion.The rigidity that the column 18 of described mechanical arm 10 and described crossbeam 19 add described mechanical arm 10 makes to reduce perpendicular to the displacement of described gripper shoe 14.
Compared to prior art, described mechanical arm 10 is provided with the weight that opening 142 alleviates described mechanical arm 10, and described robot work speed is strengthened, and efficiency improves.Described mechanical arm 10 also comprises column 18 and crossbeam 19 makes described mechanical arm 10 maintaining rigidness when being provided with opening 142 not decline.
