Description

Technical Field

[0001] The utility model relates to the technical field of clamping jaws, in particular to a single-cylinder cylindrical connecting rod clamp. Background Art

[0002] Currently, cylindrical palletizing is typically achieved using a clamping mechanism. These grippers typically utilize multiple pneumatic cylinders, with each cylinder controlling one claw. However, since the air pipes of the multiple cylinders are not perfectly aligned and can vary in length, they cannot be fully synchronized. Consequently, the clamping effect is suboptimal, and the palletizing process is unreliable. Furthermore, the use of a rack and pinion V-block clamping mechanism requires significant space, is complex, and is both costly and requires a large opening and closing size. Furthermore, it cannot achieve tangency with the outer wall of the cylindrical palletizing cylinder, resulting in poor palletizing results.

[0003] The current multi-cylinder grippers have problems such as unsatisfactory clamping effect and poor palletizing effect, which need to be improved.

[0004] Therefore, in view of the shortcomings of the above solution in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of striving for excellence, and with the assistance of professional knowledge and experience, as well as after many ingenuity and experiments, a single-cylinder cylindrical connecting rod clamp is specially provided to solve the problems of unsatisfactory clamping effect and poor stacking effect of multi-cylinder grippers.

[0035] A height adjustment frame 15 is provided on the cylindrical positioning plate 5 . An elongated hole 13 is provided on the height adjustment frame 15 along the vertical direction. A height-adjustable proximity switch 14 is provided at the elongated hole 13 .

[0036] During implementation, four first support arms 17 are set outside the first bracket 8, and the angle between adjacent first support arms 17 is ninety degrees.

[0040] When the cylinder 4 of this clamp contracts, the first bracket 8 moves downward relative to the second bracket 10, the degree of inward folding of the first connecting rod 9 and the second connecting rod 11 increases, the bottom of the second connecting rod 11 opens, and the clamp is in an open state; when the cylinder 4 extends, the action is opposite to the above, and the clamp head 12 clamps.

[0041] When the clamp is in use, the cylinder positioning plate 5 contacts the top of the cylinder to position it, the cylinder 4 contracts, and the four claws 20 contract synchronously to clamp the cylinder. Figure 3 .

At the same time, the connecting flange 6 and the first bracket 8 will also move relative to each other under the guiding effect of the first guide rod 2. The buffer spring 1 cooperates to realize the second buffer defense line and double buffer protection.
