Description

Technical Field

[0001] The utility model relates to the technical field of transmission equipment, in particular to a program-controlled magnetic hanging telescopic crossbeam. Background Art

[0002] The program-controlled magnetic crane is an important part of the logistics line automatic transmission device. It uses electromagnets to absorb workpieces to achieve automatic cross-line distribution and transportation of materials to various production equipment. The traditional program-controlled magnetic crane is to place a certain number of electromagnets on a beam of fixed length. When the electromagnets are first installed, the spacing is manually adjusted for fixed installation. The program-controlled magnetic crane drives the fixed magnets on the beam through the lifting mechanism to lift and transport the materials.

[0003] With the general trend of automated factory development, the demand for logistics line automation transmission devices is increasing due to the high cost of using a large number of workers in a single production line and the high error rate of processing information flow. At the same time, the equipment in the production line is becoming more and more complicated. In new projects, multiple single production lines that have been used for a long time often need to be connected to achieve automated production. The length of the single production line of old equipment varies. Some production lines are shorter and some are longer. When they are connected together, the same programmable magnetic crane is needed to transport materials. At this time, due to the limited distance between the electromagnet and the beam in the height direction, the shorter production line will interfere with the programmable magnetic crane beam. If both the long production line and the short production line use shorter beams, the material collapses more seriously and may collide seriously with the production line equipment itself. Therefore, the beam needs to be extended to achieve the line automation production of single production lines of different lengths. Summary of the invention

[0015] The utility model discloses a program-controlled magnetic lifting telescopic beam, such as Figure 1-4As shown, it includes a fixed beam 1, in which a telescopic beam 2 that can move along the length direction is installed. By moving the telescopic beam 2, the length of the entire beam can be changed, so that it can be suitable for the suction and transportation of materials of different lengths, and realize the connected automatic production of single-machine production lines of different lengths.

[0016] In order to realize the movement of the telescopic beam 2, a rack 3 is installed on the telescopic beam 2, a support plate 4 is provided on the side of the fixed beam 1, a telescopic motor 5 is installed on the support plate 4, and a driving gear 6 meshing with the rack 3 is installed on the output shaft of the telescopic motor 5. An avoidance groove 7 is opened on the fixed beam 1 corresponding to the position of the driving gear 6. When the telescopic motor 5 is started, it can drive the telescopic beam 2 to telescopically move relative to the fixed beam 1.

[0017] In order to achieve the attraction and fixation of the material, a plurality of electromagnet blocks 8 are installed at the bottom of the fixed beam 1, and an electromagnet block 8 is also installed at the bottom of the end of the telescopic beam 2 extending out of the fixed beam 1. The bottoms of all the electromagnet blocks 8 are kept on the same horizontal line to fit the surface of the material. After the electromagnet blocks 8 are powered on, strong magnetic attraction is obtained to absorb and fix the material. A vertical lifting device such as an oil cylinder electric push rod can be installed on the fixed beam 1, and the material is grabbed by the attraction of the electromagnet block 8 to the material, and the material is transported by the lifting device.

[0018] Furthermore, in order to position and guide the telescopic beam 2 in the fixed beam 1, vertical guide wheel clamping mechanisms are installed on both the upper and lower sides of the fixed beam 1, and the vertical guide wheel clamping mechanisms can limit the upper and lower positions of the telescopic beam 2. Figure 5 As shown, each vertical guide wheel clamping mechanism includes a first pad 9 , first L-shaped top blocks 10 are arranged on both sides of the first pad 9 , a first T-shaped plate 11 is also installed on the first pad 9 , and the first T-shaped plate 11 is located between the two first L-shaped top blocks 10 .

[0019] A first long slot 12 is provided on the first T-shaped plate 11, a screw hole is provided on the first pad 9, a first locking bolt 13 matched with the screw hole is installed in the first long slot 12, and the first long slot 12 allows the first T-shaped plate 11 to move vertically relative to the fixed crossbeam 1. A screw hole is also provided in the first L-shaped top block 10, and a first adjusting bolt 14 is installed in the screw hole. The first adjusting bolt 14 passes through the first L-shaped top block 10 and contacts the first T-shaped plate 11. The first T-shaped plate 11 can be moved upward by rotating the first adjusting bolt 14.

[0020] A vertically arranged first guide wheel 15 is also installed on the first T-shaped plate 11, a first hole groove 16 matching the first guide wheel 15 is opened on the fixed beam 1, a pad rail 17 is installed on the upper part of the telescopic beam 2, and the rack 3 is arranged on the pad rail 17.

[0021] In order to achieve the limitation and guidance of the telescopic beam 2 in the left and right directions, the left and right sides of the fixed beam 1 are both equipped with a transverse guide wheel clamping mechanism, such as Figure 6 As shown, each lateral guide wheel clamping mechanism includes a second pad 18 , on which two groups of second L-shaped top blocks 19 are provided, and on which a second T-shaped plate 20 is also installed, and the second T-shaped plate 20 is located between the two second L-shaped top blocks 19 .

[0022] A second long slot 21 is provided on the second T-shaped plate 20, a screw hole is provided on the second pad 18, a second locking bolt 22 matched with the screw hole is installed in the second long slot 21, and the second long slot 21 allows the second T-shaped plate 20 to be adjusted to move laterally relative to the fixed crossbeam 1. A screw hole is also provided in the second L-shaped top block 19, and a second adjusting bolt 23 is installed in the screw hole. The second adjusting bolt 23 passes through the second L-shaped top block 19 and contacts the second T-shaped plate 20. Rotating the second adjusting bolt 23 can push the second T-shaped plate 20 to move laterally.

[0023] A horizontally arranged second guide wheel 24 is also installed on the second T-shaped plate 20, and a second hole groove 25 matching the second guide wheel 24 is opened on the fixed beam 1. When the second adjusting bolt 23 is rotated, the second guide wheels 24 on both sides can be driven to clamp in the width direction of the telescopic beam 2, thereby realizing lateral guiding and limiting of the telescopic beam 2.

[0024] Furthermore, in order to limit the movement of the telescopic beam 2 to a necessary length and prevent the telescopic beam 2 from moving out of the fixed beam 1, as shown in FIG. Figure 7 As shown, a mechanical dead stop 26 is installed at one end of the telescopic beam 2 located inside the fixed beam 1.

A drag chain 29 is also installed at the end of the telescopic beam 2 extending out of the fixed beam 1.

[0025] Furthermore, in order to form a certain buffer when the device absorbs materials and leave a margin for vertical movement and lifting of the lifting device, thereby improving the service life of the device, the electromagnet block 8 is fixed to the bottom of the fixed beam 1 and the telescopic beam 2 through a magnetic mounting seat, such as Figure 8 As shown, the magnetic mounting seat includes a T-rail 30 arranged at the bottom of the fixed beam 1 or the telescopic beam 2, and a T-slider 31 is mounted on the T-rail 30.

A spring 36 is also mounted on the outer periphery of the connecting bolt 32 between the T-shaped slider 31 and the hanging plate 33. By rotating the nut 35, the pre-tightening force of the disc spring 34 and the spring 36 can also be adjusted to improve the stability when sucking different materials.

[0027] The fixed crossbeam 1 and telescopic crossbeam 2 can both be sleeved, which can hide most of the fixing and transmission mechanisms inside the rectangular tube, reducing the external space occupied. Secondly, the sleeve method allows the entire crossbeam to maintain a large torsional strength. The rectangular steel tube of the telescopic crossbeam 2 is supported by a variety of guide wheels, and the guide wheels are designed to be adjustable with a self-made guide rail surface preload. This design can reduce the processing accuracy while ensuring the support strength, so as to reduce the manufacturing cost. Secondly, by adjusting the preload of the guide wheels on both sides, the gap between the driving gear and the rack can be adjusted, reducing the risk of uneven force on the gear and rack, and ensuring the reliability of the transmission.

[0028] A mechanical dead stop 26 is designed at the end of the telescopic beam 2 to prevent accidents when the electrical control fails or the detection switch fails. The end of the telescopic beam 2 extending from the fixed beam 1 can also use a magnetic mounting seat as a mechanical limit, so as to limit the movement of the telescopic beam 2 from two directions. The transmission of the telescopic beam 2 can use a motor-driven large-modulus rack to ensure the stability of the overall mechanism. The motor uses a variable frequency motor plus an encoder configuration to adjust the extension position of the tail magnet to adapt to the interconnection of more production lines of different lengths.
