Description

Technical Field

[0001] The present invention relates to the technical field of fixtures for inspecting and calibrating robotic arms, and more specifically, to fixtures for inspecting and calibrating robotic arms and methods of using the same.

Background Art

[0002] A robotic arm is a programmable device with multiple degrees of freedom and can perform various complex movements in space. A robotic arm is usually composed of a series of links, and each link can move freely within a certain range, so the robotic arm can execute various different tasks. The robotic arm may be used in an industrial production line to realize the automation of production and improve productivity, or may be used in fields such as medical, aerospace, and deep sea to execute various dangerous or delicate tasks. The robotic arm includes advantages such as high precision, high efficiency, high reliability, and high safety, and at the same time, there are some limitations, such as the need for programming and debugging, operation and maintenance, etc. At present, robotic arms have already been widely applied in various fields, and with the continuous development of technology, the future of the application of robotic arms should be broader.

[0003] In the installation of a robotic arm, in order to prevent the deviation of the robotic arm from the installation position, it is necessary to position the installation position. Currently, positioning and installation are performed manually by humans. During the installation process, the robotic arm is likely to sway and cause a certain degree of deviation, so the position deviation of the robotic arm after installation is caused, and it is necessary to improve the accuracy. Also, the stability of the robotic arm will decrease.

[0004] Therefore, currently, positioning and installation are carried out manually by humans. During the installation process, the robot arm tends to sway and cause a certain degree of deviation. As a result, positional deviation occurs after the installation of the robot arm, and it is necessary to improve the accuracy. Also, in order to effectively prevent the stability of the robot arm from decreasing, it is necessary to design and modify a jig for inspecting and calibrating the robot arm.

It is obvious that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the present invention.

[0021] As shown in FIGS. 1 to 6, the jig for inspecting and calibrating a robotic arm and its usage method provided by the present invention includes a processing robotic arm 1.

The screw 41 is slidably connected to the side wall of the jig box 3 for inspection and calibration. Inside the screw 41, a screw sleeve 42 is screwed. Inside the screw sleeve 42, a positioning block 43 is fixedly connected. The positioning block 43 is used in cooperation with the robotic arm base 2. At the bottom of the jig box 3 for inspection and calibration, a mounting port 5 and a fixing groove 6 used in cooperation with the mounting port 5 are formed.

Currently, positioning and installation are carried out manually by humans. During the installation process, the robot arm is prone to swaying and causing a certain degree of deviation, so the position deviation of the robot arm after installation is caused, and it is necessary to improve the accuracy. Also, by solving the problem that the stability of the robot arm decreases, the effect of accurately installing after calibration is achieved.

[0024] Referring to FIG. 5, the position limiting assembly 10 includes a positioning rod 101. The positioning rod 101 is slidably connected to the inspection and calibration jig box 3.

[0025] As one technical optimization solution of the present invention, by providing the position limiting assembly 10, the position outside the positioning block 43 can be limited, so that the stable movement of the positioning block 43 can be guaranteed, facilitating the use by the user.

[0026] Referring to FIG. 5, an operation block 11 is fixedly connected to the outside of the screw 41, and a bearing seat 12 is movably connected to the surface of the screw 41.

[0028] Referring to FIG. 5, a support plate 13 is fixedly connected to the bottom of the bearing seat 12, and the support plate 13 is fixedly connected to the surface of the inspection and calibration jig box 3.

[0029] As one technical optimization solution of the present invention, by providing the support plate 13, the bearing seat 12 can be supported and its position can be limited, effectively avoiding the wobbling of the bearing seat 12, and facilitating the use by the user.

[0030] Referring to FIG. 5, a slider 14 is fixedly connected to the bottom of the positioning block 43, and a slide groove 15 slidably connected to the slider 14 is formed on the inner wall of the bottom of the inspection and calibration jig box 3.

[0031] As one of the technical optimization solutions of the present invention, by providing the slider 14, the position of the bottom of the positioning block 43 can be restricted, so that the inclination and wobbling of the positioning block 43 can be avoided, and the use by the user can be facilitated.

[0032] Referring to FIG. 2, at the bottom of the inspection and calibration jig box 3, one or more anti-vibration pads 16 are fixedly connected. On both the front and back of the inspection and calibration jig box 3, mounting blocks 17 are fixedly connected. At the bottom of the mounting block 17, a pad block 18 is fixedly connected.

[0033] As one of the technical optimization solutions of the present invention, by providing the anti-vibration pads 16, buffering can be performed at the bottom of the inspection and calibration jig box 3, the sliding of the inspection and calibration jig box 3 from the mounting position can be avoided, and the stability of the inspection and calibration jig box 3 can be improved.

[0034] Referring to FIG. 1, the following steps are included.

[0035] In step S1, when the user needs to position and calibrate the processing robot arm 1, first, the inspection and calibration jig box 3 is attached to an appropriate position. After the user places the processing robot arm 1 into the inspection and calibration jig box 3, the operation block 11 is rotated. The operation block 11 rotates the screw 41. The rotation of the screw 41 moves the nut sleeve 42. By locking the positioning block 43 to the robot arm base 2 of the processing robot arm 1 by the movement of the nut sleeve 42, the processing robot arm 1 can be positioned so that the processing robot arm 1 does not move. Then step S2 is executed for installation.

[0036] In step S2, after the user inserts the fixing bolt 7 into the fixing groove 6 and screws it onto the robot arm base 2 of the processing robot arm 1, the fixing bolt 7 is fixed using the nut 8, thereby ensuring the stability of the fixing bolt 7 and effectively guaranteeing the stability and excellent accuracy of the mounting position after installation.

[0037] The operating principle and usage procedure of the present invention are as follows. When in use, if the user needs to position and calibrate the processing robot arm 1, first, the inspection and calibration jig box 3 is mounted at an appropriate position. After the user places the processing robot arm 1 into the inspection and calibration jig box 3, the operation block 11 is rotated. The operation block 11 rotates the screw 41, and the rotation of the screw 41 moves the screw sleeve 42. By locking the positioning block 43 to the robot arm base 2 of the processing robot arm 1 due to the movement of the screw sleeve 42, the processing robot arm 1 can be positioned so that the processing robot arm 1 does not move. Then, the installation is carried out. After the user inserts the fixing bolt 7 into the fixing groove 6 and screws it onto the robot arm base 2 of the processing robot arm 1, the fixing bolt 7 is fixed using the nut 8, thereby ensuring the stability of the fixing bolt 7 and effectively guaranteeing the stability and excellent accuracy of the mounting position after installation. Currently, positioning and installation are performed manually by humans. During the installation process, the robot arm is likely to sway and cause a certain degree of deviation, resulting in a positional deviation of the robot arm after installation, and there is a need to improve the accuracy. Also, by solving the problem of the decrease in the stability of the robot arm, the effect of accurately installing after calibration is achieved.

[0038] As described above, according to the inspection and calibration jig for the robotic arm and its usage method, by combining the processing robotic arm 1, the robotic arm base 2, the inspection and calibration jig box 3, the transmission assembly 4, the screw 41, the screw sleeve 42, the positioning block 43, the mounting port 5, the fixing groove 6, the fixing bolt 7, the nut 8, the protection assembly 9, the protection cover 91, the screw 92, the position limiting assembly 10, the positioning rod 101 and the stop block 102, currently, positioning and mounting are performed manually by humans. During the mounting process, since the robotic arm sways and is prone to a certain degree of deviation, a positional deviation occurs after the robotic arm is mounted, and it is necessary to improve the accuracy. Also, the problem of the decreased stability of the robotic arm has been solved.
