Abstract

The invention relates to a mechanical arm, in particular to a mechanical arm with a pinion for opening clamping jaws. The mechanical arm comprises an air cylinder, the two clamping jaws, two gears and a guide rail. The air cylinder is fixedly connected with the guide rail, a driving arm of the air cylinder is hinged to the driving end of the first clamping jaw which is hinged to the guide rail, and the driven end of the first clamping jaw is used for clamping a workpiece. The first gear is fixedly connected with the first clamping claw, the hinged point of the first clamping jaw is located on the circle center line of the first gear, the second gear is meshed with the first gear, the second gear is fixedly connected with the driving end of the second clamping jaw, the second clamping jaw is hinged to the guide rail, the hinged point of the second clamping jaw is located on the circle center line of the second gear, and the driven end of the second clamping jaw is used for clamping the workpiece. According to the mechanical arm, the synchronous rate of the clamping components of the clamping jaws is high, and the success rate of workpiece clamping and the stability of clamping in the process of workpiece transporting are improved.

Description

The manipulator that uses pinion that jaw is opened and closed

Technical field

The present invention relates to a kind of manipulator, especially relate to a kind of manipulator that uses pinion that jaw is opened and closed.

Background technology

In automation assembling, processing or production process, manipulator is widely used in clamping and the transfer of various workpiece.And manipulator is mainly the effect of clamping of playing by jaw.In order to guarantee success rate and the stability of clamping, manipulator is had relatively high expectations to the sync rates of each hold assembly of jaw, because asynchronous during the work of each hold assembly, and the situation that the workpiece that occurs being held comes off in the process shifting.

Summary of the invention

The object of the present invention is to provide a kind of manipulator, each hold assembly sync rates of its jaw is high, the stability clamping in the success rate of raising piece-holder and workpiece transportation.

The present invention is achieved by the following technical solutions: the manipulator that uses pinion that jaw is opened and closed, comprise cylinder, two jaws, two gears, guide rail, cylinder is fixedly connected with guide rail, the drive end of the hinged jaw of actuating arm of cylinder, No. one jaw is articulated with on guide rail, the driven end holding workpiece of a jaw, wherein, No. one gear is fixedly connected with a jaw, the pin joint of a jaw is positioned on the center of circle line of a gear, a gear of No. two gear engagements, No. two gears are fixedly connected with the drive end of No. two jaws, being hinged on guide rail of No. two jaws, the pin joint of No. two jaws is positioned on the center of circle line of No. two gears, the driven end holding workpiece of No. two jaws.

The invention has the beneficial effects as follows: gear is fixedly connected with jaw, the pin joint of two jaws is positioned at the center of circle line of two gears simultaneously, is in order to guarantee that at jaw, in clamping process, two gears remain engagement.The conduction orientation upper cylinder that pitch wheel is exerted all one's strength, a jaw, a gear, No. two gears, No. two jaws form an integral body, thereby while guaranteeing two jaw clampings with transmitting workpiece, keep synchronizeing the stability clamping in the success rate of raising piece-holder and workpiece transportation.

Further, cylinder is spring reset cylinder, and spring reset cylinder economy also can be well suited for the work of holding workpiece.

Further, guide rail is dovetail guide, and dovetail guide kinematic accuracy is high, and motion stabilization is applicable to transporting holding workpiece.。

Accompanying drawing explanation

Fig. 1 is that structure of the present invention is used pinion to make the example structure schematic diagram of the manipulator of jaw switching.

The specific embodiment

By reference to the accompanying drawings shown in 1, the manipulator that uses pinion that jaw is opened and closed, comprise cylinder 1, a jaw 2 and No. two jaws 5, a gear 3 and No. two gears 4, dovetail guide 7, cylinder 1 is fixedly connected with dovetail guide 7, the drive end of the hinged jaw 2 of actuating arm of cylinder 1, a hinged dovetail guide 7 of jaw 2, the driven end holding workpiece 6 of a jaw 2, wherein, No. one gear 3 is fixedly connected with a jaw 2, the pin joint of a jaw 2 is positioned on the center of circle line of a gear 3, a gear 3 of No. two gear 4 engagements, No. two gears 4 are fixedly connected with the drive end of No. two jaws 5, being hinged on dovetail guide 7 of No. two jaws 5, the pin joint of No. two jaws 5 is positioned on the center of circle line of No. two gears 4, the driven end holding workpiece 6 of No. two jaws 5, cylinder 1 is spring reset cylinder.

During use, gear is fixedly connected with jaw, and the pin joint of two jaws is positioned at the center of circle line of two gears simultaneously, is in order to guarantee in the present invention in clamping process, and a gear 3 and No. two gears 4 remain engagement.Conduction orientation upper cylinder that pitch wheel is exerted all one's strength 1, jaw 2, gear 3, No. two gears 4, No. two jaws 5 form an integral body, thereby while guaranteeing a jaw 2 with No. two gear 4 clampings and transmitting workpiece, keep synchronizeing the stability clamping in the success rate of raising workpiece 6 clampings and workpiece 6 transportations.

Above is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
