Description

Technical Field

[0001] This utility model belongs to the field of robotic equipment, and specifically relates to a door frame welding slag grinding mechanism based on an industrial robot. Background Technology

[0002] A door frame weld slag grinding mechanism is a device specifically designed to clean residual weld slag after door frame welding. However, in automobile manufacturing, this mechanism has several drawbacks. Due to limitations in welding technology, door frame welding often results in excessive weld slag, excessive height of slag, and unevenness around the weld. When faced with complex door frame shapes and diverse weld seams, precise and comprehensive grinding is difficult, easily leaving grinding dead zones, such as narrow spaces like the inner corners of the door frame. The conventional solution is to design dedicated fixtures for positioning assistance; however, the rapid pace of automotive product updates means that old fixtures are easily rendered obsolete after new door frame designs are introduced, leading to a significant increase in manufacturing costs. Furthermore, these non-robot grinding mechanisms typically have low automation levels, making it difficult to adjust grinding force, speed, and other parameters in real time according to the actual weld slag conditions. This results in inconsistent grinding quality, sometimes over-grinding and damaging the door frame, and sometimes under-grinding, affecting subsequent processes. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a door frame welding slag grinding mechanism based on an industrial robot, including: a base assembly, a robotic arm assembly 200 and a grinding assembly. The robotic arm assembly 200 for controlling the movement of the grinding assembly is rotatably mounted on the upper surface of the base assembly. A grinding assembly for grinding door frame welding slag is mounted on the end of the robotic arm assembly 200 away from the base assembly. The base assembly includes a base body 110 for mounting the robotic arm assembly 200. The robotic arm assembly 200 includes a hinge seat 210, and the upper end of the hinge seat 210 is hinged to the robotic arm body 220.

[0022] Please see Figures 1 to 3 As the first embodiment of this utility model: a base plate 100 is installed on the lower surface of the base body 110, a motor 120 for driving the rotating seat 140 to rotate is installed on the outer surface of the base body 110, a control box 130 is installed on the left side surface of the motor 120 through the base body 110, and a rotating seat 140 is rotatably installed on the upper surface of the base body 110 through the motor 120.

[0023] A hinge seat 210 is installed on the side surface of the rotating seat 140 away from the base body 110. A 1cm gap is provided between the lower surface of the rotating seat 140 and the upper surface of the base body 110. A robotic arm body 220 is hinged to the end of the hinge seat 210 away from the rotating seat 140.

[0024] The robotic arm body 220 is hinged to a mounting base 240 at one end away from the hinge seat 210. A rotary motor 250 is mounted on the rear surface of the mounting base 240. A mounting rod 260 is rotatably mounted on the front surface of the mounting base 240. A mounting head 270 is mounted on the end of the mounting rod 260 away from the mounting base 240.

[0025] In use, the user first installs the base body 110 in a suitable position using the base plate 100. After installation, the user can control the device independently via a PLC control program or a control box 130 (both the control program and control box 130 are existing technologies and will not be described in detail here). During control, the motor 120 can be started first (the output shaft of the motor 120 is equipped with an output gear, and the lower surface of the rotating seat 140 is equipped with an input gear; the output gear and input gear are meshed together; the motor 120 is a stepper motor). When the motor 120 rotates, it drives the input gear to rotate via the output gear, thereby causing the rotating seat 140 to rotate above the base body 110, thus controlling the rotation. The robotic arm assembly 200 on the upper surface of the selection seat rotates. While the robotic arm assembly 200 rotates via the rotating seat 140, the user can also activate the electric push rod 230 behind the robotic arm body 220 to change the angle of the electric push rod 230 relative to the mounting seat 240, thereby changing the grinding position of the grinding assembly at any time. Then, the grinding assembly is activated to achieve the grinding effect on the door frame. Since the robotic arm assembly 200 can rotate 360° during use, it can approach the door frame from different angles and grind the welding slag on various parts. Especially some hard-to-reach corners and edges, such as the inner corners of the door frame and the parts connected to the wall, can be fully covered and ground by the flexible rotation of the robotic arm, avoiding grinding dead corners.

[0026] Please see Figures 1 to 3As a second embodiment of the present utility model: an electric push rod 230 is hinged between the mounting base 240 and the hinge base 210, and the grinding assembly includes a protective frame 320, a connecting rod 300 and a grinding disc 310.

[0027] A connecting rod 300 is installed at the end of the mounting head 270 away from the mounting rod 260. A grinding disc 310 is installed at the end of the connecting rod 300 away from the mounting head 270. A protective frame 320 is installed on the outer surface of the connecting rod 300. An opening is provided on the outer surface of the protective frame 320.

[0028] The front surface of the grinding disc 310 is parallel and aligned with the front surface of the protective frame 320, and the front surface of the grinding disc 310 abuts against the weld slag surface of the door frame.

[0029] When using the equipment, during the grinding operation following the steps of the first embodiment, the rotary motor 250 on the rear surface of the mounting base 240 is first started. The output shaft of the rotary motor 250 drives the mounting rod 260 on the front surface of the mounting base 240 to rotate. When the mounting rod 260 rotates, it drives the mounting head 270 to rotate, which in turn drives the grinding disc 310 to rotate. Since the front surface of the grinding disc 310 is parallel and aligned with the front surface of the protective frame 320, the grinding disc 310 is intercepted by the protective frame 320 during grinding and then discharged from the opening of the protective frame 320, thus achieving the purpose of interception. Since the grinding component is installed at the end of the robotic arm component 200 away from the base component, the grinding position can be precisely controlled. With the robotic arm component 200, the grinding component can be accurately positioned on the part of the door frame that needs to be ground, ensuring the grinding quality.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
