However, existing grinding equipment typically only grinds one side of the stator; grinding the other side requires a flipping mechanism, resulting in a complex structure, cumbersome operation, and room for improvement in grinding quality. Additionally, existing grinding equipment can only grind stators of specific heights; modifications are needed to grind stators of different heights, limiting its versatility. Utility Model Content

Detailed Implementation

[0023] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figure 1 As shown, a grinding mechanism for post-weld inspection and processing of the iron core of a new energy stator drive motor includes a base plate 100, a stand 200 mounted on the base plate 100, a lifting module 300 mounted on the upper part of the stand 200, an upper grinding component 400 mounted on the slide plate of the lifting module 300, a lower grinding component 500 mounted on the lower part of the stand 200, a clamping component 600 mounted on the upper part of the stand 200, and a moving module 700; the upper grinding component 400 and the lower grinding component 500 are arranged opposite to each other; the base plate 100 is mounted on the slide plate of the moving module 700. Specifically, the lifting module 300 is a linear module driven by a handwheel; the moving module 700 is a linear module driven by a motor.

[0025] By setting the upper grinding component 400 and the lower grinding component 500 relative to each other, the welding protrusions on the upper and lower surfaces of the stator can be ground without flipping the stator. At the same time, the height of the upper grinding component 400 can be adjusted by the lifting module 300 to adapt to stators of different heights. The structure is simple, the grinding quality is significantly improved, and it has strong versatility.

[0026] like Figure 1As shown, both the upper grinding assembly 400 and the lower grinding assembly 500 include a grinding cylinder 410, a mounting plate 420, an elastic floating group 430, a mounting clamp 440, and a grinding assembly 450. In the upper grinding assembly 400, the grinding cylinder 410 is mounted on the slide plate of the lifting module 300, and in the lower grinding assembly 500, the grinding cylinder 410 is mounted on the lower part of the upright frame 200. The mounting plate 420 is mounted on the drive end of the grinding cylinder 410, the mounting clamp 440 is connected to the mounting plate 420 through the elastic floating group 430, and the grinding assembly 450 is mounted on the mounting clamp 440.

[0027] By setting the elastic floating group 430, the grinding group 450 can perform elastic floating grinding on the welding protrusions, avoiding over-grinding and damaging the stator, and ensuring the grinding quality.

[0028] like Figure 2 As shown, the elastic floating assembly 430 includes a floating block 431, a floating cylinder 432, a guide sleeve, a guide shaft, and an elastic element. The floating block 431 is located on the side of the mounting plate 420 away from the mounting clamp 440. The floating cylinder 432 is mounted on the mounting plate 420, and its driving end is connected to the middle of the floating block 431. The guide sleeve is mounted on the mounting plate 420, and the guide shaft slides through the guide sleeve. One end of the guide shaft is connected to the floating block 431, and the other end is connected to the mounting clamp 440. The elastic element is sleeved on the guide shaft. One end of the elastic element abuts against the guide sleeve, and the other end abuts against the mounting clamp 440. Specifically, there are two guide sleeves, symmetrically arranged on both sides of the floating cylinder 432. The elastic element is a spring. The cooperation between the guide sleeve and the guide shaft ensures the stability of the grinding assembly 450 during the grinding process.

[0029] like Figure 1 As shown, the grinding assembly 450 includes an electric spindle 451 and a grinding head 452; the electric spindle 451 is mounted on a mounting clamp 440, and the grinding head 452 is mounted on the output end of the electric spindle 451. Specifically, the grinding head 452 is a tungsten carbide end mill.

[0030] like Figure 1 As shown, both the upper grinding assembly 400 and the lower grinding assembly 500 also include a fine-tuning limit group 460. The fine-tuning limit group 460 includes a connecting plate, a slide, a mounting block, a limit plate, and screws. The slide is connected to the mounting clamp 440 via the connecting plate, and the slide is located on the side of the mounting clamp 440 away from the mounting plate 420. The limit plate is connected to the slide via the mounting block, and the end of the limit plate away from the mounting block has a limit hole corresponding to the grinding assembly 450. The screw threads through the mounting clamp 440 and abut against the slide. Specifically, the slide adopts a cross roller type, and a micrometer is integrated on the slide to ensure adjustment accuracy; the limit plate is triangular; the grinding head 452 passes through the limit hole.

[0031] Manually rotating the screw causes the slide table to move the limit plate slightly up and down, allowing the grinding head 452 to protrude slightly from the limit hole. During grinding, the limit plate contacts the stator, forming a mechanical hard limit.

[0032] like Figure 1 As shown, the fine-tuning limit group 460 also includes a baffle, which is installed on the side of the limit plate away from the mounting block to prevent the spread of dust during the grinding process.

[0033] like Figure 1 As shown, the clamping assembly 600 includes a clamping cylinder, a clamping plate, and a pad. The clamping cylinder is mounted on the upper part of the stand 200. One end of the clamping plate is connected to the drive end of the clamping cylinder, and the pad is mounted on the bottom surface of the other end of the clamping plate to prevent rigid contact between the clamping plate and the stator during the pressing process. Specifically, the clamping plate is L-shaped. The clamping assembly 600 provides flexible positioning of the stator during the grinding process, preventing movement and further ensuring grinding quality.

[0034] like Figure 1 As shown, the grinding mechanism for post-weld inspection and processing of the stator drive motor core in new energy vehicles also includes a collection tray 800, which is mounted on the base plate 100. The collection tray 800 works in conjunction with a dust suction head to collect waste generated during the grinding process.

[0035] During operation, the stator is transferred to the rotating platform 900 by a conveying mechanism (not shown in the figure). Figure 2 As shown, the moving module 700 drives the base plate 100 to move closer to the stator until the upper grinding assembly 400 and the lower grinding assembly 500 are aligned with a certain welding protrusion. The pressing assembly 600 presses down to position the stator, and the floating cylinder 432 drives the floating block 431 to rise and fall, so that the limiting plate contacts the stator. Finally, the grinding assembly 450 performs grinding. The rotating platform 900 drives the stator to rotate, realizing the grinding of other welding protrusions.
