Description

Technical Field

[0001] The invention relates to the technical field of metal material grinding, in particular to a grinding device for metal structure manufacturing. Background Art

[0002] Metal structures usually refer to various parts or more complex assemblies made of metal materials. They are widely used in aviation, construction, automobile and other industries. The design and manufacture of metal structures need to comprehensively consider their strength, toughness, corrosion resistance and other aspects to ensure their reliability and durability in different environments. Metal materials themselves are favored by the industrial field because of their high strength and excellent machinability, but the realization of these properties depends on reasonable design and fine manufacturing process, especially the requirements for their surface quality. For example, the key part in the automobile suspension system, the lower arm, is a typical metal structure. The lower arm connects the wheel and the body, bears the impact and load of the vehicle during driving, and its function is to support the wheel and maintain the smooth driving of the vehicle.

[0003] During the production and processing of the lower arm, due to the influence of cutting, casting or stamping processes, burrs and tiny irregularities often appear on its surface, making the surface roughness fail to meet the requirements. If these burrs are not removed, it will not only affect the dimensional accuracy of the lower arm, but also easily cause interference or aggravate wear during the assembly process, thereby affecting the performance stability of the lower arm in the suspension system. Therefore, the grinding device has become an indispensable tool in the production of the lower arm. According to different uses, the grinding device can be divided into manual grinding, electric grinding and automatic grinding to adapt to different production environments and process requirements.

[0004] Traditional grinding devices mostly use fixed grinding heads, which lack flexibility. The grinding heads can only be maintained in a single direction or fixed angle for processing, and cannot flexibly adjust the angle according to the complex curved structure of the lower arm surface and the needs of different areas. This results in the grinding equipment being able to effectively process certain specific areas of the lower arm, and it is difficult to meet the full range of grinding needs of various parts. In addition, most grinding devices lack intelligent perception and feedback mechanisms, and are unable to identify the specific shape and surface characteristics of the current grinding position, nor can they automatically adjust the grinding force, angle and position according to the specific requirements of different areas, resulting in a lack of flexible control during the grinding process and the inability to achieve multi-degree-of-freedom adjustment. The shape of the lower arm is complex, including curved surfaces, grooves, and parts of different thicknesses and angles. Each part has different requirements for grinding, but the grinding device with a simple structure can only process flat and easily accessible areas. Summary of the invention

The image sensor 16 and the laser displacement sensor 17 can be conveniently used for detection while the lower swing arm is being polished.

[0048] Please see attached Figure 3 and attached Fig. 9 , the detection system includes:

[0049] A data processing module, which is used to analyze and process the detected data and communicate it;

[0050] A grinding control module, which is used to control the grinding assembly to adjust the grinding;

[0051] The mobile adjustment module is used to drive the grinding component to move and adjust.

[0052] The data processing module includes:

[0053] A data analysis unit is used to receive data transmitted by other modules, analyze and process the polished surface, and determine whether the surface is qualified;

[0054] Feedback decision unit, which is used to generate feedback signals based on data analysis results to determine whether the grinding is qualified, whether secondary grinding is required, etc.

[0055] The data processing module plays a core role in the entire grinding system. Its main function is to receive, analyze and process real-time data from various detection sensors to ensure the intelligence and high precision of the grinding process. The module first obtains detection data from various sensors such as image sensors 16 and laser displacement sensors 17, including key information such as the quality, flatness and smoothness of the grinding surface. Subsequently, the data processing module uses the built-in algorithm to conduct a comprehensive analysis of these data to determine whether the grinding effect meets the predetermined quality standards.

[0056] The grinding control module is the core component for performing grinding operations in the entire system. It is responsible for accurately adjusting the working state of the grinding component according to instructions to achieve effective processing of the workpiece surface. The module flexibly adjusts the angle, position and force of the grinding disc 22 by controlling multiple motors and transmission mechanisms in the grinding component to meet the multi-angle and multi-directional grinding requirements of different workpiece surfaces. According to the analysis results transmitted by the data processing module, the grinding control module will automatically adjust the angle and speed of the grinding disc 22 to ensure that the contact surface during the grinding process is uniform and meets the quality standards. It can also perform a secondary grinding operation when it detects that the grinding effect does not meet the standards, thereby effectively improving the processing fineness and consistency of the finished product.

[0057] The mobile adjustment module is mainly responsible for driving the grinding components to adjust and precisely position the grinding components in the system, ensuring that the grinding process can adapt to different parts and complex structures of the workpiece. Through the cooperation of the electric slide rail 1 7, the electric slide rail 2 10 and the cylinder 1 8, the mobile adjustment module can realize the smooth movement of the grinding components in multiple directions, allowing the grinding head to accurately reach the specified position, thereby covering the entire workpiece surface. Whether it is necessary to move in the horizontal direction to process a larger plane workpiece, or to make fine adjustments in the vertical direction to deal with irregular parts of the surface, the module can respond flexibly.

[0058] Please see attached Figure 1 -Attached Figure 3 The clamping assembly includes a cylinder 29, which is fixedly connected to the top of the top plate 5, and a clamping plate 13 is fixedly connected to the output end of the cylinder 29, and a plurality of anti-slip strips 14 are fixedly connected to one side of the clamping plate 13. A plurality of supporting legs 2 are fixedly connected to the bottom of the operating table 1, and a fan 3 and a control panel 4 are fixedly connected to the side of the operating table 1 away from the supporting legs 2.

[0059] The top plate 5 can conveniently support and fix the cylinder 2 9, so that the cylinder 2 9 is more stable when working. When the cylinder 2 9 is working, it can conveniently drive the clamping plate 13 to work at the same time. When the clamping plate 13 is working, it will drive multiple anti-slip strips 14 to move, so as to facilitate clamping and fixing the lower swing arm. At the same time, the anti-slip strips 14 can prevent sliding during the clamping of the lower swing arm, and the operation platform 1 can be conveniently supported and fixed under the action of multiple supporting legs 2, making the operation platform 1 more stable.

[0060] Working principle: when the lower swing arm is being polished and adjusted, the electric slide rail 7 will work, and when the electric slide rail 7 works, it will drive the cylinder 8 to translate, and after the cylinder 8 moves to the required position, it will drive the electric slide rail 2 10 to move downward, and after the electric slide rail 2 10 moves to the required position, it will drive the connecting plate 18 to translate, and when the connecting plate 18 moves to the required position, one of the motors 20 will work, and when one of the motors 20 works, it will drive the worm 27 to rotate, and when the worm 27 rotates, it will drive the worm wheel 26 to engage and rotate at the same time, and when the worm wheel 26 rotates, it will drive the adjusting frame 24 to flip through the rotating rod 25, so that the angle of the grinding disc 22 can be adjusted, and when the other motor 20 works, it will drive the adjusting frame 28 to flip, and when the adjusting frame 28 flips, it will drive the grinding disc 22 to adjust at multiple angles.

[0061] When collecting debris, start the air pump 30. When the air pump 30 is working, it will draw the air inside the operating table 1 through the exhaust pipe 31, so that negative pressure is generated inside the operating table 1. When negative pressure is generated inside the operating table 1, the debris generated during grinding will be drawn through the collection groove 15. After the debris enters the interior of the operating table 1, it will be filtered and collected by the collection box 11, and the drawn air will be discharged through the exhaust pipe 32.

[0062] When the collected debris is to be processed collectively, the pull plate 33 is manually pulled upward to move, and when the pull plate 33 moves upward, the pull rod 36 is driven to move upward at the same time, and when the pull rod 36 moves upward, the limit plate 38 is driven to move, and when the limit plate 38 moves, the spring 37 is squeezed, and when the limit plate 38 squeezes the spring 37 at the same time, the block 35 is driven to move, so that the block 35 is disengaged from the slot 34, and after the block 35 is disengaged from the slot 34, the operating table 1 and the collection box 11 can be separated, and then the collected debris can be processed collectively.

[0063] When the lower swing arm is clamped and fixed, the cylinder 2 9 is started. When the cylinder 2 9 works, it drives the clamping plate 13 to move, and when the clamping plate 13 moves, it drives multiple anti-slip strips 14 to move at the same time. When the clamping plate 13 and the anti-slip strips 14 move, the lower swing arm can be clamped and fixed.
