Description

Technical Field

[0001] The utility model belongs to the technical field of metal frame positioning, and in particular relates to a rectangular wire frame positioning and clamping mechanism. Background Art

[0002] At present, the processing of rectangular wire mesh is through the combination welding of rectangular wire frame and horizontal (vertical) steel wire. Before the wire is arranged, the rectangular wire frame needs to be placed horizontally on the pallet for feeding. This process is to manually remove the rectangular wire frame vertically hanging on the hanging rack and place it horizontally in a predetermined position, waiting for the robot to grab it. Due to the position limitation of the assembly line processing, manual operation can only be performed on one side of the processing equipment. For large-sized rectangular wire frames, it is difficult to control the falling speed and falling position of the rectangular wire frame on the farther side when the rectangular wire frame is manually leveled on one side, which is easy to damage the rectangular wire frame or cause the rectangular wire frame to be inaccurately positioned, making it difficult for the robot to grab it. Summary of the invention

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See attached Figure 1-3 A rectangular wire frame positioning and clamping mechanism includes a first positioning mechanism 1 and a second positioning mechanism 2 for positioning the wires. Among the four wires constituting the rectangular wire frame 3, two parallel wires are supported and positioned by the first positioning mechanism 1, and the other two parallel wires are supported and positioned by the second positioning mechanism 2; the supporting point of the first positioning mechanism 1 for supporting the wires and the supporting point of the second positioning mechanism 2 for supporting the wires are on the same horizontal plane. The first positioning mechanism includes a fixed seat 1.1 and a positioning block 1.2. The fixed seat 1.1 is fixedly arranged on the mounting platform. The fixed seat 1.1 is connected to the positioning block through a plurality of guide rods 1.3. The bottoms of the plurality of guide rods are connected to the fixed seat. The tops of the plurality of guide rods 1.3 are slidably connected in the positioning block 1.2. A plurality of buffer springs 1.4 are arranged between the fixed seat 1.1 and the positioning block 1.2. The buffer springs 1.4 and the guide rods 1.3 are sleeved on the outer wall of the guide rods 1.3 in a one-to-one correspondence. A positioning groove 1.5 is arranged above the positioning block 1.2. The upper part of the positioning groove 1.5 is arranged in a V-shaped opening structure. A clamping mechanism for horizontally clamping the rectangular wire frame is arranged above the rectangular wire frame. The second positioning mechanism 2 is a Y-shaped bracket. The wire forming the rectangular wire frame 3 is placed in the fork at the upper part of the Y-shaped bracket.

[0022] Based on the above technical solution, the iron wires supported by the first positioning mechanism 1 are located on both sides of the operating position, and the iron wires supported by the second positioning mechanism 2 are located in front of the operating position. After the operator removes the iron wire rack on the hanging frame, he places the first iron wire in the forked opening of the upper part of the two Y-shaped brackets close to his side, first locates the first iron wire position of the iron wire rack, and then holds the iron wire to control the falling speed of the far end of the iron wire rack, so that the iron wires on both sides enter the positioning groove of the second positioning mechanism, and the far side iron wire falls into the forked opening of the upper part of the Y-shaped bracket. When the iron wire enters the positioning groove 1.5, it is buffered by the buffer spring 1.4 to prevent the iron wire frame from being bent and damaged by the impact force. The four sides of the iron wire frame are all positioned to ensure accurate position and facilitate the gripping of the clamping mechanism.

[0023] Furthermore, the V-shaped opening structure extends longitudinally below to form a rectangular opening structure that matches the diameter of the wire. The V-shaped opening facilitates the wire to enter the positioning groove, and the rectangular opening facilitates accurate positioning of the wire.

[0024] Furthermore, each iron wire used to form a rectangular iron wire frame is supported and positioned by two first positioning mechanisms 1 or two second positioning mechanisms 2, and the two first positioning mechanisms 1 or two second positioning mechanisms 2 are distributed at both ends of the iron wire, so as to ensure that the positioning of the large-sized iron wire frame 3 is more stable.

[0025] Furthermore, the clamping mechanism is moved by pneumatic drive, and the clamping mechanism includes two pneumatic clamping seats 5 fixed at both ends of the channel steel 4. A slide 6 is controlled to slide in each pneumatic clamping seat 5 by a high-pressure air source. A clamping claw 7 is fixedly connected below the slide 6, and is clamped on the opposite sides or opposite sides of the two parallel sides of the rectangular wire frame 3 by the clamping claws 7 below the two pneumatic clamping seats 5.

[0026] Furthermore, the clamping jaws 7 are arranged in a stepped shape, and the bottom edge of the clamping jaws is arranged in a horizontal direction. The bottom edge of the clamping jaws 7 is located below the rectangular wire frame to set up the wire frame 1.

[0027] Furthermore, two clamping jaws 7 are connected to the bottom of each pneumatic clamping seat 5, and the stepped extension directions of the two clamping jaws 7 are symmetrically arranged, and the two clamping jaws 7 are respectively used to clamp the opposite sides and the opposite sides of the two parallel sides of the rectangular wire frame 3. The corresponding clamping jaws can be used according to the size of the wire frame and the working conditions.

[0028] Furthermore, the clamping mechanism is provided in two sets in parallel, and the four groups of clamping claws of the two clamping mechanisms are respectively fixed at the four corners of the rectangular wire frame 3.

[0029] Furthermore, the two sets of clamping mechanisms are fixedly connected via a connecting frame 8 and move synchronously, and a moving frame 9 is connected above the connecting frame 8 to drive the movement.

[0030] Based on the above technical solution, after the four clamps 7 clamp the wire frame 3, the mobile frame 9 drives the clamps 7 and the wire frame 3 to move slightly upward through the connecting frame 8, and after leaving the first positioning mechanism 1 and the second positioning mechanism 2, the clamps are translated onto the tray through the mobile frame 9, and the clamps are retracted and separated from the wire frame. The mobile frame 9 can be driven by commonly known common technology.
