Description

Mechanical clamping jaw buffer stop

Technical Field

The utility model discloses mechanical automation technical field, concretely relates to mechanical clamping jaw with buffering impact force.

Background

The mechanical clamping jaw is used as an execution tool for the industrial robot to carry out grabbing and assembling operations, and the gripping capability, the operation stability and the like of the mechanical clamping jaw have important influences on the efficiency and the reliability of the operation process.

The traditional mechanical clamping jaw is rigidly connected with the mechanical arm, when the part is operated in running water, the space position of the part clamped by the clamping jaw is preset, when the part clamping position is mistakenly stacked with two or more parts, the longitudinal height of the part is larger than the preset part picking height of the mechanical arm, the part is collided by the mechanical clamping jaw, the collision force is transmitted to the rigid joint of the mechanical arm, although the force of collision at each time is very small, the damage and the motion precision of the mechanical arm can be caused by long-time accumulation, or a product is collided

Therefore, to the above problem, the utility model provides a new technical scheme.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mechanical clamping jaw with buffering collision force effect, the result of use of protection arm.

The utility model discloses a realize through following technical scheme:

the utility model provides a mechanical clamping jaw buffer stop, includes base, bottom plate, backup pad, guide arm, connecting rod and splint, base lower extreme fixed mounting has the bottom plate, base upper end fixed mounting has the backup pad, be equipped with the fly leaf directly over the backup pad, the backup pad upper end is equipped with a plurality of guide arm, be equipped with the guide pin bushing of a plurality of and guide arm looks adaptation on the fly leaf, be connected with the guide pin bushing through the guide arm between backup pad and the fly leaf, the base both sides are equipped with splint, be connected through a plurality of connecting rod between the splint of both sides, the connecting rod is installed on the base.

Further, a spring is arranged between the supporting plate and the movable plate.

Furthermore, a displacement sensor is arranged on one side of one guide sleeve on the movable plate.

Furthermore, a plurality of through holes are formed in the base, and the connecting rod penetrates through the through holes to be connected with the clamping plates on two sides.

Furthermore, the connecting rod is movably connected with the clamping plate.

The utility model has the advantages that: the utility model provides a mechanical clamping jaw passes through the guide arm that sets up on backup pad and the fly leaf and the cooperation of guide pin bushing to and the effect of spring, when mechanical clamping jaw receives the impact force of collision, the guide arm drives the base and moves up, thereby most punching press power has been cushioned, compare traditional rigid connection, the joint of arm has been directly conducted to the punching press power has been avoided, cause the damage to the arm, simultaneously through displacement sensor's effect, mechanical clamping jaw reports to the police when the guide arm moves to the maximum stroke, prevent further impact, thereby mechanical clamping jaw can't cushion and causes the damage to the arm.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Wherein: 1. the device comprises a base, 2, a bottom plate, 3, a supporting plate, 4, a movable plate, 5, a guide rod, 6, a guide sleeve, 7, a clamping plate, 8, a connecting rod, 9, a spring, 10 and a displacement sensor.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the mechanical clamping jaw anti-collision device comprises a base 1, a bottom plate 2 and a supporting plate 3, guide arm 5, connecting rod 8 and

splint

7, 1 lower extreme fixed mounting of base has

bottom plate

2, 1 upper end fixed mounting of base has backup pad 3, be equipped with fly leaf 4 directly over

backup pad

3, 3 upper ends in backup pad are equipped with a plurality of guide arms 5, be equipped with the guide pin bushing 6 of a plurality of and 5 looks adaptations of guide arm on the fly leaf 4, be connected with guide pin bushing 6 through guide arm 5 between backup pad 3 and the

fly leaf

4, 1 both sides of base are equipped with splint 7, be connected through a plurality of connecting rod 9 between the splint 7 of both sides, connecting rod 9 is installed on base 1, be equipped with spring 9 between backup pad 3 and the fly leaf 4, one of them guide pin bushing 6 one side-mounting has displacement sensor 10 on the fly leaf 4, a plurality of through-hole has been seted up.

In this technical scheme, this mechanical clamping jaw is used for pressing from both sides the work piece and gets, shifts, because be rigid connection between traditional mechanical clamping jaw and the arm, also can do the arm to mechanical clamping jaw's impact force on, the characteristic is in the stress point department such as the joint of arm, and long-time impact can cause very big influence in the performance and the precision of arm. When the mechanical clamping jaw is impacted by hard impact in the process of a workpiece, the guide rod 5 at the upper end of the supporting plate 3 is matched with the guide sleeve at the upper end of the movable plate 4, the base 1 at the lower end of the supporting plate 3 moves towards the direction of the guide rod 5 under the action of stamping force, the guide rod drives the impact force to become the moving thrust which tends to move upwards through the buffering effect of the spring 9, so that the impact force on the mechanical clamping jaw is punched, meanwhile, the spring 9 is reset, the upper end of the movable plate 4 is provided with a displacement sensor for measuring the moving position of the guide rod, when the displacement exceeds a set value, an.

The utility model provides a mechanical clamping jaw passes through the guide arm that sets up on backup pad and the fly leaf and the cooperation of guide pin bushing to and the effect of spring, when mechanical clamping jaw receives the impact force of collision, the guide arm drives the base and moves up, thereby most punching press power has been cushioned, compare traditional rigid connection, the joint of arm has been directly conducted to the punching press power has been avoided, cause the damage to the arm, simultaneously through displacement sensor's effect, mechanical clamping jaw reports to the police when the guide arm moves to the maximum stroke, prevent further impact, thereby mechanical clamping jaw can't cushion and causes the damage to the arm.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
