A high-strength robotic arm

Abstract

This application provides a high-strength robotic arm, relating to the technical field of robotic arms. It includes a rod tube with a rectangular cross-section and a filling frame housed within the rod tube. A slot is provided on the side of the rod tube, allowing the filling frame to be moved in and out of the rod tube. By installing the filling frame inside the rod tube, the mechanical strength of the robotic arm is increased. The slot on the side of the rod tube allows for convenient installation of the filling frame according to actual needs. Furthermore, a steel plate is used instead of a conventional square tube; under the same mechanical strength requirements, a thinner steel plate can be selected, resulting in a lighter overall weight and lower cost for the robotic arm.

Description

Technical Field

[0001] This application relates to the technical field of robotic arms, and in particular to a high-strength robotic arm. Background Technology

[0002] Robotic arms are mostly made of stainless steel alloys, and are high-strength, high-plasticity, and high-impact toughness steel structural components manufactured through processes such as forging, machining, heat treatment, and surface treatment. The main stress form is axial tension.

[0003] The existing robotic arms mainly have the following problems: Common robotic arms use carbon structural steel square tubes. The stress inside the square tubes is unreasonable. To meet the greater mechanical strength requirements, the wall thickness of the square tubes is mainly increased. The weight of the robotic arm also increases accordingly, resulting in low load-bearing efficiency and an inability to meet the ever-increasing demand for mechanical strength. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, a high-strength robotic arm is proposed.

[0005] This application provides a high-strength robotic arm, including a rod tube with a rectangular cross-section; it also includes a filling frame disposed inside the rod tube; the side of the rod tube has a slit, through which the filling frame can be moved into and out of the rod tube.

[0006] Preferably, the filling frame includes a longitudinal support plate, which is arranged along the axial direction of the rod tube.

[0007] Preferably, the filling frame further includes a cross-section support plate, the cross-section of which is the same as the inner cross-section of the rod tube.

[0008] Preferably, the filling frame further includes a support tube that rests against the inner side of the rod tube.

[0009] Preferably, the support tube and the pipe gap are arranged opposite to each other; the pipe gap is located at the bottom end of the tube, and the support tube is located at the top end of the tube.

[0010] Preferably, the pipe slot is rectangular.

[0011] Preferably, it also includes a reinforcing plate, which fixes the bottom end of the rod tube.

[0012] Preferably, the rod tube is made of bent steel plate.

[0013] The beneficial effects of this utility model are:

[0014] This application increases the mechanical strength of the robotic arm by installing a filler frame inside the rod tube. The side of the rod tube has a slot, through which the filler frame can be easily installed according to actual needs. Furthermore, steel plates are used instead of conventional square tubes. Under the same mechanical strength requirements, steel plates with thinner walls can be selected, resulting in a lighter overall weight and lower cost for the robotic arm.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] Example

[0025] like Figures 1 to 2 As shown, a high-strength robotic arm includes a rod tube 1 with a rectangular cross-section; it also includes a filling frame 2 disposed inside the rod tube 1; a pipe slot 11 is provided on the side of the rod tube 1, through which the filling frame 2 can be moved into and out of the rod tube 1. In this embodiment, the rod tube 1 is made of bent steel plate.

[0026] This application increases the mechanical strength of the robotic arm by installing the filling frame 2 inside the rod tube 1. The side of the rod tube 1 is provided with a tube slot 11, which allows the filling frame 2 to be easily installed according to actual needs. Furthermore, by using a steel plate instead of a conventional square tube, a thinner steel plate can be selected under the same mechanical strength requirements, resulting in a lighter overall weight and lower cost for the robotic arm.

[0027] The filling frame 2 includes a longitudinal support plate 21, which is arranged along the axial direction of the rod tube 1. In this embodiment, the longitudinal support plate 21 is arranged inside the rod tube 1 in the vertical direction.

[0028] The filling frame 2 also includes a cross-section support plate 22, the cross-section of which is the same as the inner cross-section of the rod tube 1.

[0029] The filling frame 2 also includes a support tube 23, which is attached to the inner side of the rod tube 1.

[0030] The support tube 23 is positioned opposite to the tube gap 11; the tube gap 11 is located at the bottom end of the tube 1, and the support tube 23 is located at the top end of the tube 1.

[0031] The 11-slot joint is rectangular.

[0032] It also includes a reinforcing plate 3, which is fixedly installed outside the pipe joint 11; in this embodiment, the reinforcing plate 3 is fixed to the bottom end of the pipe 1.

[0033] In this embodiment, the rod tube 1 is made of steel plate by bending. Multiple support tubes 23 are provided and are attached to the same position on the steel plate. This allows for accurate control of the shape of the steel plate after folding, ensuring that the shape of the cross-section of the rod tube 1 is consistent from front to back. The tube seam 11 is located at the notch where the steel plate is not spliced, making it easy to process.

[0034] In this embodiment, taking a robotic arm with a length of 2500mm as an example, the weight and cost of the two robotic arms are compared under the same mechanical strength conditions, as shown in the table below:

[0035]

[0036] Therefore, the robotic arm of this application has significantly reduced weight and cost compared to conventional robotic arms.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
