Description

Technical Field

[0001] The present invention relates to the technical field of sheet processing, and particularly to an automatic positioning device for multi-specification flat plates and stepped plates. Background Art

[0002] In the fields of machining, automation equipment, and assembly production lines, etc., multi-specification flat plates and stepped plates often need to be accurately placed on multi-layer structures for subsequent processing, assembly, or inspection operations. In the past positioning mechanisms, due to the lack of sufficient flexibility in specifications and levels, it was often difficult to meet the positioning requirements of flat plates with different specifications. At the same time, traditional positioning mechanisms may have problems such as inaccurate positioning and poor stability during operation, which not only affect production efficiency but may also lead to a decline in product quality.

[0003] To solve the above problems, an automatic positioning mechanism for multi-specification and multi-layer flat plates has emerged. This automatic positioning mechanism has greater flexibility and adaptability, and can meet the positioning requirements of flat plates with different specifications in multi-layer structures. At the same time, through precise design and manufacturing processes, the positioning mechanism can ensure the accuracy and stability of positioning, thereby improving production efficiency and product quality.

[0004] The application of the automatic positioning mechanism for multi-specification and multi-layer flat plates will greatly improve the production efficiency and product quality in the manufacturing industry and the field of mechanical engineering. With the continuous progress of technology and the continuous expansion of applications, this positioning mechanism will be applied in more fields and make important contributions to the development of industrial automation and intelligent manufacturing.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a multi-specification flat plate and stepped plate automatic positioning device, which has the following beneficial effects:

[0022] 1. The multi - specification planar plate and stepped plate automatic positioning device is equipped with an X - axis drive assembly, an equidistant adjustment assembly, and a positioning finger assembly set according to different positioning products. It can support the positioning of planar plates or stepped plates of multiple specifications. The positioning finger assembly is equipped with an electric cylinder for driving the fingers, which is independently controlled. Each set of main finger assemblies and sub - finger assemblies can act independently or multiple sets can act together, which can meet the positioning of single - layer products and multi - layer products, improving work efficiency. The multi - layer design enables the mechanism to simultaneously position multiple planar plates, realizing multi - task parallel processing and improving the operation efficiency of the production line. The multi - specification design endows the mechanism with good scalability, and the number of positioning layers and specifications can be increased or decreased according to actual needs to adapt to different production requirements.

[0023] 2. The two sides of the multi - specification planar plate and stepped plate automatic positioning device can be divided into a reference side end and a positioning side end. The difference is that the positioning finger assembly on the reference side end is directly fixed to the corresponding installation, and the positioning finger assembly on the positioning side end is driven by a cylinder. When positioning the product, the positioning finger assembly on the reference side reaches the specified position directly through the drive of the servo electric cylinder, and the positioning finger assembly on the positioning side first reaches a certain position through the drive of the servo electric cylinder, and then drives and clamps the sheet material through the cylinder to clamp the workpiece and complete product positioning. Therefore, the beneficial effects of the multi - specification planar plate and stepped plate automatic positioning device are mainly reflected in aspects such as high efficiency, flexibility, accuracy, durability, convenience, and scalability, providing a strong guarantee for the operation efficiency and product quality of the production line.

[0059] The automatic positioning device for multi-specification flat plate step plates is provided with four groups of X-axis drive components 3 on the front and rear sides of the main body frame 1. Each set of X-axis drive components 3 controls the corresponding mounting frame component 4 to move in the X-axis direction. There are eight sets of positioning finger components 5 on each mounting frame component. In this way, there are 32 sets of positioning finger components 5. When one layer or multiple layers of plates are arranged under the press 2, the staff can set different contact components 9 according to the different plates. The 32 sets of contact components can be adjusted in the four directions of up, down, left, and right, and then one layer or multiple layers of plate materials are positioned. In special cases, the auxiliary positioning component 10 can also be started for auxiliary positioning. The auxiliary positioning component 10 includes a lifting plate component arranged in the bottom plate of the main body frame 1. The lifting plate component is lifted upward by the power devices on both sides, so that the upper plate material is further positioned. During the positioning process, the equidistant adjustment component 6 can automatically adjust the distance up and down to be compatible with products of different thicknesses, thereby improving the efficiency and realizing the positioning of multiple layers of products.

[0060] The multi - specification planar plate and stepped plate automatic positioning device is equipped with an X - axis drive assembly, an equidistant adjustment assembly, and a positioning finger assembly 5 set corresponding to different positioning products. It can realize the positioning of planar plates or stepped plates of multiple specifications. The positioning finger assembly 5 is equipped with an electric cylinder for driving the fingers independently controlled. Each group of main finger assemblies 7 and sub - finger assemblies 8 can act independently or multiple groups can act together, which can meet the positioning of single - layer products and multi - layer products, improving work efficiency. The multi - layer design enables the mechanism to position multiple planar plates simultaneously, realizing multi - task parallel processing and improving the operation efficiency of the production line. The multi - specification design makes the mechanism have good scalability, and the number of positioning layers and specifications can be increased or decreased according to actual needs to adapt to different production requirements.

[0061] The two sides of the multi - specification planar plate and stepped plate automatic positioning device can be divided into a reference side end and a positioning side end. The difference is that the positioning finger assembly 5 on the reference side end is directly fixed to the corresponding installation, and the positioning finger assembly 5 on the positioning side end is driven by a cylinder. When positioning the product, the reference - side positioning finger assembly 5 is directly driven by a servo electric cylinder to reach the specified position. The positioning finger assembly 5 on the positioning side first reaches a certain position driven by a servo electric cylinder, and then drives and clamps the sheet material through the cylinder to clamp the workpiece and complete the product positioning.

[0062] In summary, the beneficial effects of the multi - specification planar plate and stepped plate automatic positioning device are mainly reflected in aspects such as high efficiency, flexibility, accuracy, durability, convenience, and scalability, providing a strong guarantee for the operation efficiency and product quality of the production line.
