DETAILED DESCRIPTION

[0019] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0020] like Figures 1 to 3As shown, the width-adjustable steel stacking clamp comprises a mounting frame 1, wherein a first clamping jaw 2 and a second clamping jaw 3 are provided below the mounting frame 1 and are arranged to cooperate with each other for clamping. The first clamping jaw 2 and the second clamping jaw 3 are completely located below the mounting frame 1 to facilitate clamping the steel section below. A lateral adjustment component is connected between the mounting frame 1 and the first clamping jaw 2, and the lateral adjustment component drives the first clamping jaw 2 to slide horizontally and adjust the width between the first clamping jaw 2 and the second clamping jaw 3. Two vertical mounting plates 4 and a lifting plate 5 are provided on the mounting frame 1. The second clamping jaw 3 is installed at the bottom end of the mounting vertical plate 4, and the mounting vertical plate 4 and the lifting vertical plate 5 are hinged by a parallel four-link connection 12. The lifting vertical plate 5 is vertically slidably installed on the mounting frame 1 through a lifting module. The mounting frame 1 is also provided with a lifting drive member connected to the lifting vertical plate 5. The mounting frame 1 is provided with an opening and closing guide structure for guiding the mounting vertical plate 4 to approach the first clamping jaw 2. As the lifting vertical plate 5 descends, the mounting vertical plate 4 slides along the opening and closing guide structure, causing the second clamping jaw 3 to approach the first clamping jaw 2.

[0021] The lateral adjustment assembly includes a horizontally mounted adjustment screw 6, the two ends of which are mounted on the bottom end of the mounting frame 1 via connecting supports. The adjustment screw 6 passes through the first clamping jaw 2 and the two are threadedly connected. A nut is welded to the surface of the first clamping jaw 2, and the adjustment screw 6 and the nut thread cooperate to achieve a threaded connection with the first clamping jaw 2. The end of the adjustment screw 6 away from the second clamping jaw 3 is connected to an adjustment handwheel 7, and a clamping jaw bracket 8 is fixed to the top of the first clamping jaw 2. A horizontal clamping jaw slide 9 is provided on the surface of the mounting frame 1, and the sliding limit of the clamping jaw bracket 8 is located in the clamping jaw slide 9. By rotating the adjustment handwheel 7 to drive the adjustment screw 6 to rotate, the clamping jaw bracket 8 slides horizontally along the clamping jaw slide 9, thereby changing the distance between the first clamping jaw 2 and the second clamping jaw 3. When the adjusting hand wheel 7 is no longer rotated, the first clamping jaw 2 remains stationary in this position, which is equivalent to fixing the clamping jaw. The steel section is clamped only by changing the movement and opening and closing of the second clamping jaw 3. After the second clamping jaw 3 is swung into place, the steel section is just located between the first clamping jaw 2 and the second clamping jaw 3. At this time, the position of the first clamping jaw 2 will not be forced to move. Of course, a limit screw can also be provided on the clamping jaw bracket 8, and the limit screw can achieve the purpose of position fixing by abutting against the surface of the mounting frame 1.

[0022] The lifting module includes a lifting rail 10 vertically fixed to the mounting frame 1. The lifting plate 5 is mounted on the lifting rail 10 via a lifting slide 11. The lifting plate 5 can be vertically slid and raised along the lifting rail 10 under the telescopic action of the lifting drive. The lifting rail 10 and the lifting slide 11 are linear guides commonly used in the prior art.

[0023] The parallelogram linkage 12 includes a first link, a second link, a third link, and a fourth link. The first link and the second link are located parallel to and above the third link and the fourth link. The ends of the first link, the second link, the third link, and the fourth link are respectively hinged to the mounting plate 4 and the lifting plate 5 via pins. The first link, the second link, the third link, and the fourth link are all arranged to tilt downward toward the first clamping jaw 2. The mounting plate 4 and the lifting plate 5 are both arranged vertically and connected by the parallelogram linkage 12.

[0024] The opening and closing guide structure includes a guide groove 13 provided on the surface of the mounting frame 1. The guide groove 13 includes a vertical guide groove and an inclined guide groove. The inclined guide groove extends downwardly from the bottom end of the vertical guide groove toward the first clamping jaw 2. A sliding bearing 14 is connected to the side of the mounting vertical plate 4. The sliding bearing 14 extends into the guide groove 13 and slides along the guide groove 13. When the lifting vertical plate 5 is raised or lowered, the parallelogram linkage 12 pulls the mounting vertical plate 4 to follow the lifting. The sliding bearing 14 can slide along the guide groove 13. The cooperation between the sliding bearing 14 and the guide groove 13 realizes the position limitation of the mounting vertical plate 4, thereby driving the second clamping jaw 3 to open and close. Because the mounting plate 4 is restricted to vertical translation by the parallelogram linkage 12, a combination of vertical and inclined guide grooves is employed to limit the mounting plate 4. This allows the second jaw 3 to open and avoid the impact. As the mounting plate 4 slides downward along the inclined guide grooves, the second jaw 3 gradually approaches the first jaw 2 to achieve clamping. In this embodiment, four sliding bearings 14 and four guide grooves 13 are provided, each mounted on a pin on the first and second connecting rods. The outer diameter of the sliding bearing 14 corresponds to the width of the guide groove 13, enabling stable sliding along the guide groove 13.

[0025] The lifting drive member includes a telescopic cylinder 15, one end of the telescopic rod is mounted on the mounting frame 1 through a bracket, and the other end of the telescopic cylinder 15 is connected to the lower part of the mounting plate 4 through a hinge seat. The telescopic cylinder 15 is a pneumatic cylinder with a large output force.

[0026] The first clamping jaw 2 includes a first clamping arm and a first clamping plate, the first clamping arm extends downwardly and obliquely toward the direction of the second clamping jaw 3, and the first clamping plate is horizontally arranged at the bottom end of the first clamping arm; the second clamping jaw 3 includes a second clamping arm and a second clamping plate, the second clamping arm extends downwardly and obliquely toward the direction of the first clamping jaw 2, and the second clamping plate is horizontally arranged at the bottom end of the second clamping arm. The first clamping arm and the second clamping arm are arranged obliquely toward each other, which is conducive to the first clamping plate and the second clamping plate to smoothly extend into the bottom end of the steel section. As the second clamping arm is clamped, the bottom end of the steel section can be clamped by using the cooperation of the first clamping plate and the second clamping plate.

[0027] The installation frame 1 includes two installation plates arranged opposite to each other, and the installation vertical plate 4 and the lifting vertical plate 5 are located between the two installation plates.

[0028] The working principle of this embodiment is as follows:

[0029] This device is fixedly mounted on the robotic arm, and transfer and stacking are achieved as the robotic arm moves in position; before the clamping jaws operate, the adjusting hand wheel 7 is first rotated according to the corresponding steel section specifications to adjust the distance between the first clamping jaw 2 and the second clamping jaw 3 to adapt to the corresponding steel section to be transferred; then the robotic arm drives the device to move above the steel section, at this time the telescopic cylinder 15 retracts, driving the second clamping jaw 3 to move outward and upward along the guide groove 13 to open the clamping jaws, and then the robotic arm drives the device to move downward as a whole so that the first clamping jaw 2 and the second clamping jaw 3 are placed on both sides of the steel section, at this time the telescopic rod extends, driving the lifting vertical plate 5 to descend, and the sliding bearing 14 slides to the bottom end of the inclined guide groove through the parallel four-link 12, completing the merging of the second clamping jaw 3, and the first clamping jaw 2 and the second clamping jaw 3 cooperate to clamp the steel section, and then move to the stacking area with the robotic arm.
