The simple three-claw hoisting robot arm tooling is not only suitable for lifting the wheel of the train, but also suitable for the hoisting of other heavy parts.

In order to achieve the above object, the technical scheme adopted in the utility model is as follows:

A simple three-claw hoisting mechanical arm tooling, which includes a grabbing part, a supporting part and a lifting part, and the grabbing parts are evenly distributed in the circumferential direction of the supporting part at intervals of 120 degrees, and it is characterized in that: the grabbing The fetching part includes a hook and a connecting rod, the supporting part includes a suspension rod, a first hinge and a second hinge, the lifting part is a suspension ring, the first hinge is fixedly arranged at the lower end of the suspension rod, and the The second hinge is slidably arranged between the top end of the suspender and the first hinge, the upper end of the hook is movably connected with the second hinge, the upper end of the connecting rod is movably connected with the first hinge, and the connecting rod is movably connected with the first hinge. The other end of the rod drives the hook to be positioned and clamped by means of oblique pull.

Further, the connection position between the connecting rod and the hook is one-third of the length of the hook from the upper end of the hook.

Further, the hook is composed of a pole and a clamping block arranged at the lower end of the pole, and the intersection position of the clamping block and the pole has a half arc.

Further, the connecting rod is composed of a connecting rod column and connecting heads arranged at both ends of the connecting rod column, and the connecting heads are respectively hinged with the first hinge and the hook.

Further, both the first hinge and the second hinge are composed of a hinge post and three hinge joints uniformly arranged in the circumferential direction of the hinge post.

Further, the boom is specifically composed of a boom column and a boom ring movably arranged at the top of the boom column, and the boom ring is movably connected with the suspension ring.

Further, the hook and the connecting rod, the second hinge, and the connecting rod and the first hinge are all movably connected by pin shafts, washers and cotter pins.

The tooling of the hoisting mechanical arm of the utility model is convenient for three-claw clamping and pulling, easy to locate and clamp, stable in hoisting, simple in structure, low in cost, reduces the application of manpower during hoisting, and reduces production costs. The tooling is not only used in motor vehicles Wheels are also used for hoisting other workpieces. The application of this tool reduces manpower and labor costs.

Detailed ways

As shown in Figures 1-5, the lifting robot arm tooling of the present invention includes a grabbing part, a supporting part and a lifting part, and the grabbing parts are evenly distributed in the circumferential direction of the supporting part at intervals of 120 degrees, so The grasping part includes a hook 1 and a connecting rod 2, the supporting part includes a suspension rod 5, a first hinge 3 and a second hinge 4, the lifting part is a suspension ring 6, and the first hinge 3 is fixedly arranged on The lower end of the boom 5, the second hinge 4 is slidably arranged between the top of the boom 5 and the first hinge 4, the upper end of the hook 1 is movably connected with the second hinge 4, the The upper end of the connecting rod 2 is movably connected with the first hinge 3, and the other end of the connecting rod 2 drives the hook 1 to be positioned and clamped by means of oblique pull. 1 at the third of the length of the hook 1 at the upper end, the hook 1 is composed of a pole 10 and a clamping block 11 arranged at the lower end of the pole 10, the connection between the clamping block 11 and the pole 10 The position has a half-arc degree, and the connecting rod 2 is composed of a connecting rod column 13 and connecting heads 12 arranged at both ends of the connecting rod column 13, and the connecting head 12 is connected with the first hinge 3 and the hook respectively. 1 hinge, the first hinge 3 and the second hinge 4 are composed of a hinge column 14 and three hinge joints 15 uniformly arranged in the circumferential direction of the hinge column 14, and the boom 5 is specifically composed of a boom column 16 and the boom ring 17 movably arranged at the top of the boom column 16, the boom ring 17 is movably connected with the suspension ring 6, the hook is connected with the connecting rod, the second hinge and the connecting rod All are movably connected with the first hinge through a pin shaft, a washer and a cotter pin, which is flexible and convenient for disassembly and maintenance.

When the lifting mechanical arm tooling of the utility model is used, the big hook of the crane hooks the lifting ring to lift, manually put the hook on the workpiece, pull the boom to lift, and due to the effect of gravity, the three hooks automatically move closer to the center and clamp. The workpiece can be lifted up and placed in the specified position.

Considering the actual application, since the junction of the clamping block and the pole has a half-arc, the half-arc can well accommodate the workpiece there, and the joint action of the three clamping blocks can firmly hold the workpiece Positioning prevents the workpiece from falling off during the conveying process, effectively ensuring the safety of production.

Considering the practical application, the joints of the lifting ring and the boom ring are sealed by welding to avoid the damage of the heavy lifting ring during lifting, so as to avoid the occurrence of production accidents.
