Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to an octagonal tube gripper for industrial robots. Background Technology

[0002] In automotive manufacturing production lines, industrial robot grippers are crucial actuators. Most existing industrial robot grippers employ traditional structural designs, typically made of heavy metal materials such as steel, resulting in significant overall weight. This not only increases the robot's load, impacting its operating efficiency and energy consumption, but also places higher demands on the robot's drive and control systems, further increasing equipment costs.

[0003] Meanwhile, existing grippers, if damaged such as breakage occurs during long-term use, are often difficult to repair due to structural and material limitations, requiring complete replacement. This not only increases maintenance costs but also causes production line downtime due to component replacement, impacting production efficiency. Furthermore, the existing gripper's installation structure is complex, requiring significant time and effort from professional personnel for maintenance. The single installation and fixing method is also difficult to flexibly adapt to various devices such as reinforcing ribs and clamps, hindering efficient production line operation.

[0004] Existing technologies include grippers with integrated metal frame structures, connected to industrial robot arms via bolts and other connectors. These grippers are relatively heavy, and when damaged, they require complete disassembly and replacement, making installation and maintenance cumbersome. Furthermore, the lack of standardized installation interfaces hinders the convenient installation of various auxiliary equipment. Additionally, the use of heavy metal materials and traditional structural designs in existing industrial robot grippers results in increased weight, increasing robot load and impacting operational efficiency and energy consumption. Structural and material limitations make them difficult to repair after breakage, necessitating complete replacement and increasing maintenance costs and production line downtime. The complex installation structure and inconvenient maintenance consume manpower and time, and the lack of standardized installation interfaces prevents flexible installation of reinforcing ribs, clamps, and other equipment. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes an octagonal tube gripper for industrial robots, made of aluminum, which is lightweight, reduces the load on industrial robots, is easy to install and maintain, and can be flexibly installed on various types of equipment. This improves the operating efficiency of automobile manufacturing production lines and reduces costs. The specific technical solution is as follows: An industrial robot octagonal tube gripper comprises an octagonal tube body, a connecting mechanism, a gripping execution mechanism, and a drive device. The octagonal tube body consists of an I-shaped frame and long octagonal tubes arranged on both sides of the I-shaped frame. The I-shaped frame and the long octagonal tubes are fixed together by triangular reinforcing ribs. A mounting plate is provided on the lower side of the I-shaped frame, and the industrial robot connecting mechanism and drive device are installed below the mounting plate. The gripping execution mechanism is installed on the upper side of the I-shaped frame and is located at the front end of the octagonal tube body. The gripping execution mechanism consists of a clamping cylinder and a finger unit. The drive device is a valve island. The industrial robot connecting mechanism includes a connecting base fixed to the robot arm and a connecting plug on the octagonal tube body.

[0006] Furthermore, the octagonal tubes are made of aluminum alloy with an octagonal cross-section, and each tube has M8 screw holes evenly distributed axially. These screw holes allow for the fixing of drive units, reinforcing ribs, clamps, and other components using standard M8 bolts. The aluminum alloy material reduces weight while ensuring structural strength, and the standardized design of the M8 screw holes enables modular installation of the drive unit, facilitating rapid layout adjustments according to production needs.

[0007] Furthermore, a sealing strip is provided on the mounting plate of the valve island and the octagonal tube body to prevent gas leakage.

[0008] Furthermore, the clamping cylinder is connected to the octagonal tube body via a hinge. Under the drive of the valve island, the finger unit adaptively adjusts its gripping posture according to the shape of the workpiece (such as the bosses and holes of automotive parts). For example, when gripping a car door component, the gripper cylinder opens to a set angle under the control of the valve island, closes after aligning with the edge of the door, and achieves stable gripping through friction or mechanical engagement.

[0009] Furthermore, the positioning slot of the connecting base cooperates with the guide key of the connecting plug to achieve quick installation and disassembly of the gripper and the robot arm through a mechanical locking device (such as a snap-lock). The operation can be completed without additional tools, and the time for a single installation and disassembly can be controlled within 2 minutes.

[0010] The workflow of this utility model is as follows: the industrial robot arm drives the gripper to move above the workpiece through the connecting mechanism; the robot control system sends an electrical signal to the valve island, and the valve island switches the air path to drive the gripper cylinder to open; the gripper descends to the designated position, the cylinder closes to clamp the workpiece, and the valve island collects the cylinder positioning feedback signal and transmits it to the system; the robot arm drives the gripper to move to the target workstation, and the valve island controls the cylinder to open and release the workpiece; if maintenance or replacement of the drive device is required, the valve island can be directly disassembled through the M8 screw hole, replaced, and reinstalled.

[0011] This utility model has the following advantages: (1) Lightweight: The octagonal tube body adopts high-strength aluminum alloy material and octagonal structure design. Compared with traditional steel grippers, the weight is significantly reduced, which can effectively reduce the load of industrial robots, reduce robot operating energy consumption, and improve operating efficiency. (2) Good repairability: Due to the modular design and the main material being aluminum alloy, when a part of the gripper is damaged, only the corresponding module needs to be replaced, instead of replacing the whole thing, which greatly reduces maintenance costs and production line downtime. At the same time, aluminum alloy material has good machinability, which facilitates repair operations. (3) Convenient installation and maintenance: The quick-plug structure design of the connecting mechanism makes the installation and disassembly of the gripper simple and quick; the M8 screw holes on the octagonal tube body realize the standardized installation of auxiliary equipment, which can be quickly assembled without additional modifications, saving manpower and time, and improving the maintenance efficiency of the production line. (4) Strong adaptability: The adaptive drive design of the gripping actuator can meet the gripping needs of different workpieces in all series of models produced by Jiangling Motors; the setting of M8 screw holes allows for flexible installation of various equipment, such as the rapid switching of multiple workstations by installing a gun changing plate, or the optimization of the air circuit layout by installing a valve island, which further improves the versatility of the gripper in different production scenarios.
