Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame grinding, and in particular to a grinding device for processing electric vehicle frames. Background Technology

[0002] In the manufacturing of electric vehicles, the frame is generally manufactured by stamping, and the frame needs to be polished after stamping.

[0003] In the current technology, most frames still require manual polishing for certain details that machines cannot polish. Manual polishing is inefficient, lacks standardization, and depends on worker experience. Parameters such as weld smoothness and chamfer radius vary even within the same batch of frames. The polishing process still has a 20%-30% rework rate, and labor costs are relatively high. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a grinding device for processing electric vehicle frames.

[0005] The present invention provides a grinding device for processing electric vehicle frames, which adopts the following technical solution:

[0006] A grinding device for processing electric vehicle frames includes a worktable, a moving module, a clamping assembly, and a grinding mechanism. Two sets of the moving module and the grinding mechanism are provided. The two sets of moving modules are mounted on the worktable, and the two sets of grinding mechanisms are respectively mounted on both sides of the worktable. Each set of moving modules is connected to at least two sets of clamping assemblies. Each clamping assembly includes a moving table, two sets of cylinders, and a clamping plate. The two sets of cylinders are fixed to the moving table in a direction parallel to the moving module and are arranged opposite to each other. The output end of each cylinder is connected to the clamping plate.

[0007] Optionally, the clamping assembly further includes two sets of cylinders and a clamping plate. The two sets of cylinders are fixed to the moving platform along the vertical direction of the moving module, and the two sets of cylinders are arranged opposite to each other. The output end of the cylinder is connected to the clamping plate.

[0008] Optionally, the polishing mechanism includes a Z-axis moving component, a Y-axis moving component, and a polishing component. The Z-axis moving component is disposed on both sides of the worktable. The Z-axis moving component drives the Y-axis moving component to move up and down, and the Y-axis moving component drives the polishing component to move horizontally.

[0009] Optionally, the grinding assembly includes a slide table, a slide rail, a slider, a connecting frame, a fixed plate, a spring, a drive assembly, and a grinding head. The Y-axis moving assembly drives the slide table to move horizontally. The slide rail and the fixed plate are both mounted on the slide table. The connecting frame slides in cooperation with the slide rail via the slider. The drive assembly is mounted on the connecting frame and drives the grinding head to rotate. A push plate is mounted on the connecting frame, and the spring is positioned between the push plate and the fixed plate.

[0010] Optionally, the drive assembly specifically includes a motor, a drive wheel, a driven wheel, a belt, and a rotating shaft. The motor is mounted on the connecting frame, and the output end of the motor is connected to the drive wheel. The drive wheel and the driven wheel are driven by the belt. The rotating shaft is rotatably connected to the connecting frame, the driven wheel is mounted on the rotating shaft, and the grinding head is connected to the end of the rotating shaft.

[0011] Optionally, a pressure sensor is provided on the fixing plate, and the end of the spring is connected to the pressure sensor.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. The frame can be laterally clamped by cylinder one and clamping plate on two sets of clamping components on a set of moving modules. The moving module drives the two sets of clamping components to move horizontally. The grinding mechanism performs a polishing process on the laterally clamped frame. After the frame is polished, the frame is taken out and then the two ends of the frame are placed longitudinally on the moving tables on the two sets of moving modules. Cylinder two is activated to fix the frame on clamping plate two. Through this design, the moving module can drive the frame to the grinding mechanism to realize automatic grinding operation.

[0014] 2. The Z-axis moving assembly is set on both sides of the worktable, supporting the Y-axis assembly to move up and down. Combined with the Y-axis to drive the grinding assembly to move horizontally, it forms a precise positioning in three-dimensional space, which can adapt to the multi-angle grinding needs of workpieces of different sizes. A spring is set between the connecting frame and the fixed plate. During the grinding process, the spring deformation absorbs vibration, reduces the grinding head jumping caused by uneven workpiece surface or uneven force, and improves the consistency of the processed surface.

[0015] 3. The slide table achieves horizontal fine adjustment of the grinding head through the slide rail and slider. Combined with the elastic compensation of the spring, it can adapt to the curvature change of the workpiece surface. A pressure sensor is set on the fixed plate, and the end of the spring is connected to the pressure sensor. The compression of the spring is fed back in real time through the pressure sensor, which can dynamically adjust the correction mechanism. The pressure sensor senses the pressure of the spring in real time and controls the movement of the Y-axis moving module on the slide table so that the grinding head can always be in contact with the frame.

Each set of moving modules 2 is connected to at least two sets of clamping assemblies 3. Each clamping assembly 3 includes a moving table 31, two sets of first cylinders 32, a first clamping plate 33, a second cylinder 34, and a second clamping plate 35. The two sets of first cylinders 32 are fixed to the moving table 31 in a direction parallel to the moving module 2, and the two sets of first cylinders 32 are arranged opposite each other. The output end of the first cylinder 32 is connected to the first clamping plate 33. The second cylinder 34 is mounted in a direction perpendicular to the moving module 2. The two sets of cylinders 34 are fixed to the moving platform 31 and are arranged opposite each other. The output end of the cylinder 34 is connected to the clamping plate 35. The frame can be clamped laterally by the cylinder 32 on the two sets of clamping components 3 on the moving module 2 and the clamping plate. The moving module 2 drives the two sets of clamping components 3 to move horizontally. The polishing mechanism 4 polishes the frame that is clamped laterally. After the frame is polished laterally, the frame is taken out and then the two ends of the frame are placed longitudinally on the moving platform 31 on the two sets of moving modules 2.

Through this design, the moving module 2 can drive the frame to the polishing mechanism 4 to realize automatic polishing operation.

[0024] The grinding mechanism 4 includes a Z-axis moving assembly 41, a Y-axis moving assembly 42, and a grinding assembly 43. The Z-axis moving assembly 41 is located on both sides of the worktable 1.

Combined with the Y-axis driving the grinding component 43 to move horizontally, it forms a precise positioning in three-dimensional space, which can adapt to the multi-angle grinding needs of workpieces of different sizes. A spring 436 is set between the connecting frame 434 and the fixed plate 435. During the grinding process, the deformation of the spring 436 absorbs vibration, reduces the jumping of the grinding head 437 caused by uneven workpiece surface or uneven force, and improves the consistency of the processed surface.

[0025] The slide table 431 achieves horizontal fine adjustment of the grinding head 437 through the slide rail 432 and the slider 433.
