Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device for automotive metal castings. Background Technology

[0002] In the field of metal casting processing, grinding is a crucial step in improving the surface quality of parts. With the rapid development of the automotive industry, the shapes of automotive parts are becoming increasingly complex, with a large number of irregular structures, curved contours, and combined flange designs. These irregularly shaped metal castings face two major challenges in the grinding process: First, traditional clamping systems use rigid positioning, which can only achieve fixation in one direction, making it difficult to effectively constrain parts with complex geometric features; second, existing equipment lacks specialized clamping mechanisms for local features such as flanges and bosses, leading to vibration and displacement during processing, which seriously affects grinding accuracy and surface quality.

[0003] Existing grinding devices for irregular parts suffer from the following drawbacks: conventional three-jaw chucks or vacuum suction cups cannot meet the clamping requirements of multi-curved surfaces and asymmetrical structures; while some devices using elastic chucks can achieve a certain degree of shape adaptation, they lack secondary fixing mechanisms for locally protruding structures, leaving a risk of part loosening during high-speed grinding; furthermore, some devices employ multi-station, step-by-step processing modes, which are not only inefficient but also suffer from accumulated positioning errors due to repeated clamping, severely restricting processing accuracy. These technical bottlenecks directly lead to a low pass rate for grinding automotive metal castings and persistently high processing costs.

[0004] To address the aforementioned issues, we propose a grinding device for automotive metal castings. Utility Model Content

[0019] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a grinding device for automotive metal castings, including a body frame 1, a grinding integrated device 2, and a quick docking device 3.

[0020] The frame 1 serves as the main body of the device, and its top platform simultaneously supports the grinding integrated device 2 and the quick-connect device 3. A sliding connection design allows the grinding integrated device 2 to move freely in the horizontal direction, providing a basis for flexible subsequent processing. The vertical arrangement of the grinding end of the grinding integrated device 2 and the quick-connect device 3 ensures the stability of the grinding force direction, avoiding processing errors caused by part misalignment.

[0021] The multiple elastic insertion devices 31 evenly distributed on the base plate 33 constitute the first clamping system. Each elastic insertion device 31 is connected to the base plate 33 through an elastic element, which can adapt to the surface of parts with different curvatures and absorb the vibration energy of grinding through elastic deformation.

[0022] The magnetic center disk 32 forms a second fixing mechanism. Located at the center of a circle formed by multiple elastic insertion devices 31, the magnetic center disk 32 attracts ferromagnetic parts through a magnetic field, making it particularly suitable for castings with planar substrates, complementing the elastic clamping mechanism. The magnetic center disk 32 uses an electromagnet as its main structure; the control method and working principle are existing technologies and will not be elaborated upon.

[0023] The flexible insertion device 31 is designed with a sliding outer shell 311 incorporating a first elastic clamping block 312 and a second elastic clamping block 313.

[0024] Both the first elastic clamping block 312 and the second elastic clamping block 313 are made of rubber to avoid damage caused by hard connection and friction with the workpiece.

[0025] The horizontal sliding device 23 drives the second lead screw 233 through the second rotating wheel 232, which in turn moves the integrated top plate 231 along the horizontal slide rail 234 to achieve XY plane positioning; the lifting and grinding integrated device 21 controls the first lead screw 212 through the first rotating wheel 211, which drives the grinding machine fixed seat 213 to move vertically to complete the Z-axis adjustment.

[0026] The grinding head 214 adopts an independent drive motor design, avoiding the energy loss and vibration problems caused by traditional belt drives. The sliding connection structure between the grinding machine base 213 and the mounting bracket 22 ensures the smoothness of the lifting movement.

[0027] The pre-tightening force adjustment range of the elastic plug-in device 31 is 50N~300N; The magnetic center disk 32 has an adsorption strength that is adjustable from 0.5T to 5T. The feed speed of the grinding head 214 is 0.1 mm / s to 5 mm / s; The positioning accuracy of the horizontal sliding device 23 is ±0.05mm; The repeatability of the lifting and grinding integrated device 21 is ±0.02mm.

[0028] Working principle: The automotive metal casting to be processed is placed in the central area of ​​the quick docking device 3; Adjust the elastic plug-in device 31, first make the sliding outer shell 311 abut against the outer surface of the workpiece, and then make the first elastic clamp 312 and the second elastic clamp 313 align with the flange edge of the workpiece. Turn the magnetic center disk 32 to the set adsorption strength to help fix the component substrate; The grinding head 214 is moved to the processing starting point by the horizontal sliding device 23; Start the lifting and grinding integrated device 21 to make the grinding head contact the surface of the part and begin processing.
