Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an iron-dropping prevention device for a mechanical arm of a cutting machine. Background Art

[0002] The robotic arm is the most widely used automated mechanical device in the field of robotic technology. It is widely used in various industrial production. In the process of iron material processing through cutting machines, the robotic arm is used to transport the iron material for cutting operations to improve the overall processing efficiency.

[0003] Due to the existing iron processing production line equipment, when the operator moves the iron to the blanking rack, the normally operating mechanical arm cannot sense whether there are people working, and will automatically drop the iron according to the established procedure, resulting in injury accidents. For this reason, a special anti-iron drop device is required to improve the safety of the use of the cutting machine mechanical arm. The existing protection is provided by the set monitoring sensing equipment. When the monitoring equipment fails, it is easy for the mechanical arm to relax the iron block, which still causes safety hazards. The effect of preventing iron drop is low. In addition, due to the distance between the iron material and the blanking rack, the practice of directly relaxing the mechanical arm is easy to cause damage to the iron material and the device during placement, reducing the use effect.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0028] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0029] A device for preventing iron from falling off a cutting machine mechanical arm provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0030] Embodiment 1:

[0031] Combination Figure 1-Figure 3 As shown, the utility model provides a device for preventing iron from falling off a mechanical arm of a cutting machine.

[0032] Specifically, it includes a mechanical mounting frame 1, a mobile hanging frame 3, a support frame 4 and a blanking frame 5. Four sets of adjustable mechanical clamping arms 8 are rotatably installed on the four sides of the mechanical mounting frame 1. The four sets of mechanical clamping arms 8 clamp an iron block 2. The middle sliding frame of the mobile hanging frame 3 is provided with a hanging mounting plate 9. A hydraulic cylinder 7 is installed on the top of the hanging mounting plate 9. A compression cavity 10 is opened inside the hanging mounting plate 9. A compression plunger 11 is slidably clamped between the inner sides of the compression cavity 10. The top of the compression plunger 11 is connected to a connecting rod 12. The bottom of the compression plunger 11 is symmetrically connected to a mobile hanging rod 13. The bottom end of the mechanical mounting frame 1 is connected to a vacuum suction cup 16. An air guide hose 14 is installed between the bottom end of the hanging mounting plate 9 and the top of the vacuum suction cup 16. The output end of the hydraulic cylinder 7 is rotatably connected to the top of the connecting rod 12. The mobile hanging rod 13 The bottom ends of the components penetrate the bottom end of the lifting mounting plate 9 and are connected to the top end of the mechanical mounting frame 1. The outer side of the compression plunger 11 is sleeved with a sealing plug pad 15 at the joint between the compression cavity 10. The sealing plug pad 15 is mainly used to improve the sealing performance and enhance the compression effect of the compression plunger 11. The bottom end of the vacuum suction cup 16 is provided with an adsorption hole 20 close to the top end of the iron block 2. The adsorption hole 20 is mainly used to facilitate the vacuum suction cup 16 to adsorb the surface of the iron block 2. The air guide hose 14 penetrates the middle part of the mechanical mounting frame 1 and connects the vacuum suction cup 16 and the compression cavity 10 respectively. The operation and use of the above-mentioned components, especially the compression adsorption of the compression plunger 11 and the adsorption and fixation of the iron block 2 by the vacuum suction cup 16, cooperate with the original mechanical clamping arm 8 to prevent the iron block 2 from falling when the monitor 6 fails, thereby improving the anti-falling effect and the safety of use.

[0033] Embodiment 2:

[0034] Combination Figure 2 and Figure 3 As shown, based on the first embodiment,

[0035] Specifically, the bottom ends of the four groups of mechanical clamping arms 8 are connected to a mounting connection shell 17, a spring 18 is installed on the inner side of the mounting connection shell 17, the bottom end of the spring 18 is connected to an extrusion column block 19, and the top side of the extrusion column block 19 is slidably connected to the inner side of the mounting connection shell 17. The above-mentioned components are implemented simultaneously in column 1, and the reverse extrusion effect of the compression plunger 11 causes the iron block 2 to be driven toward the blanking rack 5. After the extrusion column block 19 squeezes the spring 18 and vibrates, the iron block 2 falls smoothly on the blanking rack 5, thereby reducing damage and improving the use effect.

[0036] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0037] Specifically, the blanking rack 5 and the mobile hoisting rack 3 are respectively installed at the lower right end and the upper right end of the support frame 4. A monitor 6 is installed on the top right side of the blanking rack 5. The monitor 6 mainly monitors whether the operator is in front of the blanking rack 5 to improve the warning effect.

[0038] The working principle and use process of the utility model are as follows: first, in order to hoist and move the iron block 2, after being clamped and fixed by the four sets of mechanical clamping arms 8 on the mechanical mounting frame 1, the compression plunger 11 at the bottom end of the connecting rod 12 is driven by the operation of the hydraulic cylinder 7 to move upward along the inside of the cavity 10, and the gas in the vacuum suction cup 16 is extracted through the air guide hose 14, so that the iron block 2 is vacuum-absorbed. When the monitor 6 fails or has no effect, the mechanical clamping arm 8 may be loosened in advance, and the vacuum suction cup 16 may be used for adsorption and stabilization to prevent the iron block 2 from falling, thereby improving the effect of preventing iron from falling off and also improving the use of the utility model. Secondly, when it is necessary to place the iron block on the blanking rack 5, through the above structure, the compression plunger 11 is pushed downward along the cavity 10 in the opposite direction to squeeze the gas in the vacuum suction cup 16 downward, and at the same time, the movable suspension rod 13 is pushed to drive the mechanical mounting frame 1 to make the mechanical clamping arm 8 move the iron block 2 toward the blanking rack 5, and the extrusion column block 19 under the connecting shell 17 installed at the bottom of the mechanical clamping arm 8 and the extrusion of the blanking rack 5 are used to squeeze and vibrate the spring 18, so that after the vacuum suction cup 16 is released, the mechanical clamping arm 8 is also released through the external control mechanism, so that the iron block 2 falls smoothly, reducing damage to the device and improving the use effect.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
