Description

Technical Field

[0001] This utility model relates to the field of metal cutting and machining, and in particular to a dual-station rotary exchange worktable. Background Technology

[0002] In laser cutting processes, worktables equipped with fixtures are often used. Among them, dual-station rotary exchange worktables are commonly used to improve processing efficiency. A dual-station rotary exchange worktable is a work platform that achieves orderly switching between two stations through rotation, and it is generally divided into an loading / unloading station and a processing station.

[0003] Chinese Patent No. CN217193628U discloses a welding robot with a dual-station rotary table, including a support base, a rotary drive device and a rotary table. The rotary drive device is mounted on the support base and drives the rotary table to rotate 180° intermittently, and can switch between clockwise and counterclockwise rotation.

[0004] Conventional rotary tables are typically large rectangular or circular platforms designed to accommodate products of different sizes. These platforms are equipped with numerous fixture mounting positions to accommodate variable fixture quantities and mounting positions. To meet load-bearing requirements, rotary tables need to be sufficiently thick, resulting in a large weight that increases both material costs and energy consumption for operation. Utility Model Content

[0005] This invention addresses the shortcomings of existing rotary worktables, which are designed as large rectangular or circular platforms to meet the high adaptability of product clamping, resulting in heavy weight, high cost, and high energy consumption. It provides a dual-station rotary exchange worktable that meets the adaptability requirements while achieving lightweight design.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A dual-station rotary exchange workbench includes a base, a workbench body, and a drive mechanism mounted on the base for rotating the workbench body. The workbench body includes a mounting platform and support arms symmetrically and horizontally mounted on both sides of the mounting platform. N (N≥2) support arm mounting seats for detachably assembling the support arms are arranged at intervals along the length direction on both sides of the mounting platform. Each side of the mounting platform is equipped with 1 to N support arms, and the support arms are axially symmetrically distributed relative to the side wall of the mounting platform. A clamp mounting plate is detachably mounted on the upper end of the support arm. The clamp mounting plates are distributed in strip or flat shape on 1 to N support arms on one side of the mounting platform.

[0008] By adopting the above solution, the flat workbench is replaced with a structure that combines an installation platform with two side support arms, which can significantly reduce the amount of material used. In addition, N support arm mounting seats are set up, and the number of support arms and the number and size of the fixture mounting plates are selected according to the area and weight of the product. The workbench adopts a lightweight design and flexible selection of support arms and fixture mounting plates, which ensures adaptability while meeting the requirements of assembly stability and lightweight.

[0009] Preferably, the support arm includes an "I"-shaped support frame and a mounting end plate that is vertically fixed to one end of the support frame and used for assembly with the support arm mounting base. The two sides of the support frame are provided with reinforcing plates that are welded to both the support frame and the mounting end plate at the end closest to the mounting end plate.

[0010] By adopting the above solution, the structure of the support arm achieves lightweighting while meeting the support performance requirements.

[0011] Preferably, the installation platform is hollow inside and has a first reinforcing rib welded in a grid pattern inside.

[0012] Using the above solution, the first reinforcing rib of the installation platform ensures the deformation resistance of the external frame, achieving lightweight while ensuring the stability of the overall structure.

[0013] Preferably, a protective baffle is fixed on the installation platform, perpendicular to the support arm, to separate the support arms on both sides of the installation platform.

[0014] Using the above solution, during laser cutting, there is a situation where chips are scattered at the workstation. Setting up protective baffles can prevent chip waste from being reduced to the loading and unloading workstations.

[0015] Preferably, the protective baffle extends beyond both ends of the installation platform and is fixedly connected to the upper surface and both ends of the installation platform.

[0016] By adopting the above solution, the contact area and fixing area between the protective baffle and the installation platform are increased, thereby increasing the robustness and stability of the assembly.

[0017] As a preferred embodiment, the protective baffle is hollow inside and has several second reinforcing ribs with weight-reducing grooves welded inside.

[0018] By adopting the above solution, the protective baffle is designed to be lightweight while ensuring its own resistance to deformation.

[0019] As a preferred option, a third reinforcing rib with a triangular cross-section and an overall frame structure is fixed between the installation platform and the protective baffle.

[0020] The above solution incorporates a lightweight design for the third reinforcing rib, resulting in a stable structure that enhances the robustness and stability of the deformation-resistant protective baffle assembly.

[0021] This utility model, by adopting the above technical solutions, has significant technical effects: replacing the flat workbench with a structure combining an installation platform and two side support arms can significantly reduce material usage. Furthermore, it is equipped with N support arm mounting seats, allowing for the selection of the number of support arms and the number and size of the fixture mounting plates based on the product's area and weight. The support arms, installation platform, and protective baffles all adopt a lightweight design with auxiliary reinforcing ribs. This workbench satisfies the adaptability of fixture assembly while also possessing the advantages of assembly stability and lightweight design. Attached Figure Description
