Description

Technical Field

[0001] The utility model relates to the technical field of robotic arms, and particularly to a novel single-axis servo rotating robotic arm. Background Art

[0002] Robotic arms are widely used in the field of industrial automation, such as in processes like assembly, handling, welding, and spraying. They can replace manual labor to complete repetitive, dangerous, or high-precision operations, significantly improving production efficiency and product quality. With the continuous improvement of industrial automation levels, the application scenarios and requirements of robotic arms have become increasingly diverse and complex, posing higher demands on their performance and reliability.

[0003] Currently, single-axis servo rotating robotic arms have been widely used in many applications due to their advantages such as simple structure, high control precision, and fast response speed. However, traditional single-axis servo rotating robotic arms still have some deficiencies, mainly reflected in the following aspects:

[0004] Insufficient stability: Due to the characteristics of the single-axis structure, the weight of the robotic arm is mainly concentrated on the cantilever and the execution end, resulting in the center of gravity of the entire device deviating from the support point, making it prone to tilting or swinging problems, which affect the stability and reliability of the device.

[0005] Limited load capacity: The weight of the cantilever and the execution end will generate large bending moments and stresses on the support structure, restricting the load capacity and working range of the robotic arm and making it difficult to meet the requirements of heavy-load or large-span operations.

[0006] Therefore, this solution specifically proposes a novel single-axis servo rotating robotic arm to solve the above problems. Summary of the Utility Model

[0007] To overcome the defects of the prior art, the purpose of the utility model is to provide a novel single-axis servo rotating robotic arm.

[0008] To achieve the above object, the technical solution of the utility model is realized as follows: A novel single-axis servo rotating robotic arm includes a base and a robotic arm. A rotating cylinder is installed on the top of the base. The top output end of the rotating cylinder is butted against a pillar. A fixed sleeve is installed at the upper end of the pillar. A cantilever is installed in front of the fixed sleeve. An axial position adjustment driving mechanism is installed inside the cantilever. The robotic arm is installed on the position adjustment end of the adjustment driving mechanism. An inclined support assembly is installed between the fixed sleeve and the position adjustment end of the adjustment driving mechanism. A reinforcing angle steel is arranged between the connection end of the fixed sleeve and the cantilever.

[0009] Preferably, the axial position adjustment driving mechanism specifically includes the following structure:

[0010] A servo motor installed at the front end inside the cantilever;

[0011] A driving lead screw docked on the output end of the servo motor;

[0012] A lead screw sleeve threadedly sleeved on the driving lead screw;

[0013] A mounting plate installed at the front end of the bottom of the lead screw sleeve. The robotic arm is specifically installed on the lower end surface of the mounting plate, and the front end of the inclined support assembly is specifically installed at the tail end of the bottom of the lead screw sleeve.

[0014] Preferably, the inclined support assembly specifically includes the following structure:

[0015] A first hinge seat installed on the front side of the fixed sleeve;

[0016] A second hinge seat installed at the tail end of the bottom of the lead screw sleeve;

[0017] An expansion rod installed between the first hinge seat and the second hinge seat.

[0018] Preferably, the robotic arm specifically includes the following structure:

[0019] A docking plate with the bottom of the mounting plate;

[0020] An arm installed at the bottom of the docking plate;

[0021] A telescopic cylinder docked at the bottom end of the arm;

[0022] A robotic hand docked on the telescopic end of the telescopic cylinder.

[0023] Preferably, the base is installed on the processing tabletop by bolts.

[0024] Preferably, the expansion rod adopts an electro-hydraulic cylinder structure.

[0025] The beneficial effects of the present utility model are reflected in:

[0026] By arranging a reinforcing angle steel between the connection end of the fixed sleeve and the cantilever, and cooperating with the inclined support assembly, the downward gravity generated at the front end of the cantilever and the robotic arm can be effectively transmitted to the pillar. This design can significantly improve the support stability of the entire device and avoid problems such as tilting or deformation of the device caused by the weight of the cantilever and the robotic arm.

[0027] The inclined support assembly adopts the structure of an expansion rod. By actively adjusting the length of the expansion rod through a hydraulic cylinder, the support force of the inclined support assembly can be adjusted in real time according to the position and load of the robotic arm. This can not only further enhance the stability of the device, but also effectively prevent the robotic arm from shaking during movement, improving the positioning accuracy and operation reliability of the robotic arm.

[0028] Through the ingenious design of the reinforcing angle steel and the inclined support assembly, the center of gravity of the entire robotic arm device is effectively adjusted to the position of the pillar. This design can minimize the impact of the cantilever and the robotic arm on the balance of the device, making the device more stable during operation and less prone to tipping over or position deviation problems.

[0029] The introduction of the inclined support assembly and the reinforcing angle steel not only improves the stability and reliability of the device, but also effectively reduces the strength and stiffness requirements for the pillar and the rotary cylinder. This means that while ensuring performance, relatively more economical and lightweight materials and components can be selected, which helps to reduce the manufacturing cost and energy consumption of the device.

[0030] Generally speaking, through the innovative design of the inclined support assembly and the reinforcing angle steel, the new single-axis servo rotary robotic arm cleverly solves the stability and reliability problems that are prone to occur in single-axis robotic arms. At the same time, by optimizing the center of gravity distribution of the device, the running smoothness and positioning accuracy of the robotic arm are improved, and its application range and working condition adaptability are expanded. This design not only enhances the performance and reliability of the device, but also takes into account economy and environmental protection, and has broad application prospects and promotion value.

A reinforcing angle steel 9 is arranged between the connection end of the fixing sleeve 4 and the cantilever 5 to effectively transfer the downward gravity of the front end of the cantilever 5 and the robotic arm 7 to the pillar 3 in cooperation with the inclined support assembly 8.

[0047] The axial position adjustment drive mechanism 6 specifically includes the following structure: The servo motor 61 is installed at the front end inside the cantilever 5, and the driving lead screw 62 is butt-connected to the output end of the servo motor 61 through a coupling.
