Technical Field
[0001] This utility model relates to the field of dual-arm gripping structure technology, and in particular to a dual-arm gripping structure for handling brick blanks. Background Technology
[0002] Aerated concrete blocks are widely used wall materials in the construction industry due to their light weight and excellent thermal insulation properties. However, before curing and molding, the blocks have low strength, are easily damaged, and have a brittle surface. This places stringent requirements on the stability of the handling process and the precision of the clamping force. Traditional handling of blocks mostly relies on manual labor and single-arm mechanical structures. Manual handling is inefficient, and single-arm mechanical structures cause the center of gravity of the blocks to shift due to the single point of force, leading to tilting and breakage. This makes it difficult to meet the needs of large-scale production. Against this background, a double-arm gripping structure for handling blocks has emerged.
[0003] The dual-arm gripping structure consists of gripping units, synchronous drive components, connecting frames, and a control system. It achieves balanced force and stable transfer of brick blanks. However, early dual-arm gripping structures had significant drawbacks. First, the clamping force adjustment relied on mechanical limits, which could not be dynamically adapted to the actual strength of the brick blanks. Excessive force could crush the brick blanks, while insufficient force could cause them to fall off. Second, the synchronization of the gripping units relied on rigid mechanical connections. After long-term use, symmetry deviations occurred due to component wear, causing local overload on the brick blanks. To address these drawbacks, existing technologies use precision guide rails and ball screw drives to replace rigid connections, improving accuracy and reducing symmetry deviations. However, the existing guide rail and ball screw structures are complex, have high maintenance costs, and are inefficient when frequently changing brick blank specifications. Furthermore, they cannot alleviate the problem of excessive force, resulting in low efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a double-arm gripping structure for handling brick blanks, aiming to improve the problems of the existing technology in being unable to alleviate excessive force and having low efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-arm gripping structure for handling brick blanks, including a fixed column, a gripping arm one fixedly connected to the rear side of the outer wall of the fixed column, a gripping wall two rotatably connected to the outer wall of the gripping arm one, a clamping mechanism provided at the bottom of the fixed column, and a rotating mechanism provided at the bottom of the gripping wall two, the rotating mechanism being used to rotate the angle. The clamping mechanism includes a cylinder, the top of which is fixedly connected to the bottom of a fixed column, and a mounting plate is fixedly connected to the bottom of the cylinder. A buffer assembly is provided at the bottom of the mounting plate.
[0006] As a further description of the above technical solution: The rotating mechanism includes a U-shaped plate, the top of which is fixedly connected to the bottom of the second gripping wall. A support column is fixedly connected to the bottom of the U-shaped plate, and a protective cover is rotatably connected to the bottom of the support column. A driving component is provided on the bottom of the inner wall of the protective cover, and a telescopic component is provided on the outer surface of the second gripping wall.
[0007] As a further description of the above technical solution: The buffer assembly includes a telescopic rod, the top of which is fixedly connected to the bottom of the mounting plate, a spring is slidably connected to the outer wall of the telescopic rod, and a connecting assembly is provided at the bottom of the telescopic rod.
[0008] As a further description of the above technical solution: The connecting assembly includes a square plate, the top of which is fixedly connected to the bottom of the telescopic rod. A pivot is rotatably connected to both the front and rear sides of the square plate, and a fixing assembly is provided on the outer wall of the pivot on the front side.
[0009] As a further description of the above technical solution: The fixing component includes a clamping plate, the inner wall of which is rotatably connected to the outer wall of the rotating shaft, a connecting column is fixedly connected to the rear side of the clamping plate, and a rotating component is provided on the right side of the clamping plate.
[0010] As a further description of the above technical solution: The rotating assembly includes a second rotating shaft, the outer wall of which is rotatably connected to the inner wall of the clamping plate, and a strip plate is rotatably connected to the outer wall of the second rotating shaft.
[0011] As a further description of the above technical solution: The drive assembly includes a motor, the bottom of which is fixedly connected to the bottom of the inner wall of the protective cover, and a gear one is fixedly connected to the output end of the motor. A gear two is meshed with the outer wall of the gear one.
[0012] As a further description of the above technical solution: The telescopic assembly includes a U-shaped seat, the rear side of which is fixedly connected to the outer wall of the second gripping wall, a short column is rotatably connected to the inner wall of the U-shaped seat, and a sliding column is rotatably connected to the inner wall of the short column.
[0013] This utility model has the following beneficial effects: 1. In this utility model, by shortening the telescopic rod and compressing the spring, the buffer is increased, which causes the square plate to move upward along with the rotating shaft. This causes the clamping plates on the left and right sides to move closer together, while the strip plates on both sides move further apart, thus clamping the brick blank. When it is necessary to release, the telescopic rod can be extended to move the clamping plates on both sides away. This achieves the function of clamping and releasing the brick blank according to the needs and can increase the buffer, thus enhancing its practicality.
[0014] 2. In this utility model, by turning on the motor, gear one drives gear two to rotate, and at the same time, the support column drives the structure at the top of the U-shaped plate to rotate. By extending and shortening the sliding column, the angle between gripping arm one and gripping arm two can be adjusted, so that brick blanks at different positions and heights can be transported according to needs, thereby increasing efficiency.
