Description

Technical Field

[0001] This utility model relates to the field of strip-shaped scrap steel grabbing, and relates to a strip-shaped scrap steel grabbing device. Background Technology

[0002] In the field of scrap steel recycling, small-sized and strip-shaped scrap steel exhibits a high degree of diversity in shape, with varying weights, mostly ranging from 5 to 50 kilograms. Currently, most common gripping devices on the market employ a single gripping mechanism. This structure exposes numerous serious problems when dealing with complex-shaped strip-shaped scrap steel. Due to the irregular shape of the scrap steel, a single gripping mechanism struggles to accurately locate its center of gravity, leading to imbalances during the gripping process. Once the gripping becomes unstable, the scrap steel is highly susceptible to falling during handling, posing a threat to the safety of on-site personnel.

[0003] In summary, the goal is to develop a scrap steel gripping device that can stably grip scrap steel of different weights and shapes ranging from 5 to 50 kilograms. Utility Model Content

Between gripper assemblies one and two, a gap is provided between the pneumatic gripper assemblies one and two. The pneumatic gripper assemblies one includes a vertical clamping plate and a cylinder one. The cylinder one drives the two sets of vertical clamping plates to move synchronously. The pneumatic gripper assemblies two include an arc-shaped clamping plate and a cylinder two. The cylinder two drives the two sets of arc-shaped clamping plates to move synchronously.

[0017] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] A strip-shaped scrap steel gripping device includes: a translation component 1, a lifting component 2, a base 3, a pneumatic gripper assembly 4, and a pneumatic gripper assembly 5. The lifting component 2 is mounted on the translation component 1 via a connecting plate 21, and the translation component 1 drives the lifting component 2 to move horizontally. The base 3 is mounted on the lifting component 2 via a connecting plate 31, and the lifting component 2 drives the base 3 to move vertically. The pneumatic gripper assembly 5 is symmetrically arranged at the lower end of the base 3, and is located between the pneumatic gripper assemblies 4. The pneumatic gripper assemblies 4 and 5 are... The pneumatic gripper assembly 25 has a gap between its components. The pneumatic gripper assembly 1 4 includes a vertical clamping plate 41 and a cylinder 42. The cylinder 42 drives the two sets of vertical clamping plates 41 to move synchronously. The pneumatic gripper assembly 2 5 includes an arc-shaped clamping plate 51 and a cylinder 52. The cylinder 52 drives the two sets of arc-shaped clamping plates 51 to move synchronously. The arc-shaped clamping plate 51 has a stepped tooth 511 on its inner side. The other set of arc-shaped clamping plates 51 has a stepped tooth 512 on its inner side that matches the stepped tooth 511. The stepped tooth 512 and the stepped tooth 511 can be inserted into each other.

[0020] like Figures 1-4 As shown, the working principle of this utility model is as follows:

[0021] This is a strip-shaped scrap steel gripping device integrating a translation component, a lifting component, a base, and two different types of pneumatic gripper assemblies. The translation component drives the lifting component to move horizontally, while the lifting component drives the base to move up and down. Pneumatic gripper assembly one drives a vertical clamping plate to move synchronously via a cylinder, primarily used to vertically grip the strip-shaped scrap steel from both sides. Pneumatic gripper assembly two uses a cylinder to drive a circular arc-shaped clamping plate to move synchronously, and the inner sides of the circular arc-shaped clamping plates on both sides are respectively equipped with interlocking stepped protrusions one and two, used to grip the scrap steel from below in a circumferential gripping motion, encircling the scrap steel inside. When dealing with strip-shaped scrap steel of different shapes, the movement of the two sets of gripper assemblies is controlled to adapt to the shape of the scrap steel, thereby completing the gripping operation.

[0022] The gap between pneumatic gripper assembly one and pneumatic gripper assembly two allows them to operate relatively independently, gripping scrap steel from different positions. By applying force at different positions of the two gripper assemblies, the influence caused by the irregular shape and center of gravity of the scrap steel is better balanced, and the line of action of the resultant force is made to pass through the center of gravity of the scrap steel as much as possible, thereby achieving stable gripping.

[0023] The multi-component collaborative design greatly improves the adaptability of the gripping device to strips of scrap steel of different shapes. The vertical clamping plate and the arc-shaped clamping plate work together to firmly clamp and restrict the scrap steel from multiple directions, effectively solving the problems of imbalance and unstable gripping caused by the difficulty in finding the center of gravity of a single gripping mechanism, and significantly reducing the risk of scrap steel falling.

[0024] As a further preferred embodiment, the stepped protrusion 511 includes three protrusions 513, with a groove 514 between the protrusions 513. The stepped protrusion 512 includes two protrusions 515, which are fitted into the grooves 514. Grooves 516 are provided between and on both sides of the protrusions 515 to accommodate the fitted protrusions 513. This convex-concave mating structure further enhances the gripping stability of the pneumatic gripper assembly 2 on strip-shaped scrap steel. Even if vibration or shaking occurs during handling, the scrap steel is extremely difficult to fall out of the gripper, effectively ensuring the safety and reliability of the gripping operation.

[0025] As a further preferred embodiment, the stepped protrusion 511 and the stepped protrusion 512 are provided in two layers. The two layers of stepped protrusions cooperate, and when the gripper closes to grab the scrap steel, the two layers of stepped protrusions work simultaneously, further strengthening the degree of gripper closure and improving the support strength for the scrap steel.

[0026] In a further preferred embodiment, the translation assembly 1 includes a motor 11, a coupling assembly 12, a screw 13, a guide rail 14, a ball nut slider assembly 15, and a frame 16. The motor 11, coupling assembly 12, and guide rail 14 are mounted on the frame 16. The screw 13 is rotatably mounted on the frame 16. The output shaft of the motor 11 is connected to the input end of the coupling assembly 12, and the output end of the coupling assembly 12 is connected to one end of the screw 13. The ball nut slider assembly 15 is inner-mounted to the screw 13 and outer-mounted to the guide rail 14. A connection 21 is mounted on the ball nut slider assembly 15. The translation assembly is composed of a motor, a coupling assembly, a screw, a guide rail, a ball nut slider assembly, and a frame. The output shaft of motor one is connected to one end of screw one via coupling assembly one. When motor one starts, its output rotational power is transmitted to screw one via coupling assembly one, causing screw one to rotate. The inner side of ball nut slider assembly one mates with screw one, and the outer side mates with guide rail one. When screw one rotates, ball nut slider assembly one, constrained by guide rail one, performs linear translational motion along guide rail one, thereby driving the connecting plate one mounted on it and the lifting assembly connected to it to move horizontally. The lifting assembly and translation assembly have the same structure and will not be described again here.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
