[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] Example 1

[0034] Combine the following Figures 1 to 6 Specifically describe the polishing equipment for the lower decorative plate of the automobile door, such as Figure 1 and Figure 2 As shown, a polishing device for the lower decorative panel of a car door includes a bearing 1, a lifting mechanism 2, a direction adjustment mechanism 3, a polishing mechanism 5 and a positioning fixture 4. The decorative panel to be polished is detachably connected to the positioning fixture 4. The polishing mechanism 5 includes a constant force spring 6, a polishing wheel 51 and a polishing connecting rod 52. The constant force spring 6 and the polishing connecting rod 52 are detachably connected, and the polishing wheel 51 is installed on the constant force spring 6.

[0035] like Figure 2 As shown, the positioning fixture 4 includes a connecting plate 41, a motor 42, a lead screw 43 and a fixture 44. The motor 42 and the lead screw 43 are detachably connected, the connecting plate 41 is rotatably connected to the lead screw 43, and the fixture 44 is installed on the upper end of the connecting plate 41.

[0036] like Figure 3 and Figure 4 As shown, the constant force spring 6 includes a spring member housing 61 and an embedded spring member 62. The spring member housing 61 is square and has an opening at the lower end. The embedded spring member 62 is installed in the cavity of the spring member housing 61. The lower end of the embedded spring member 62 is detachably connected to the upper end of the polishing wheel 51.

[0037] like Figure 5 and Figure 6 As shown, the embedded spring component 62 includes an arc sleeve 63, a main compression spring 64, an auxiliary compression spring 65 and a friction block 66. The arc sleeve 63 is cylindrical, and the upper end of the arc sleeve 63 is installed on the spring component housing 61. The main compression spring 64 is vertical in length direction and is installed in the cavity of the arc sleeve 63. The auxiliary compression spring 65 is horizontal in length direction. The auxiliary compression spring 65 is detachably connected to the inner side surface of the spring component housing 61, and the auxiliary compression spring 65 is fitted with the outer side surface of the arc sleeve 63 through the friction block 66.

[0038] The outer side surface of the arc sleeve 63 that fits with the friction block 66 is designed according to the outer contour of the decorative plate to be polished, so that when the length of the main compression spring 64 itself changes, the length of the auxiliary compression spring 65 changes accordingly. When the main compression spring 64 moves up, the main compression spring 64 is compressed again, and the upward elastic force applied by the main compression spring 64 to the arc sleeve 63 increases. At this time, the length of the auxiliary compression spring 65 becomes shorter and compressed, so the downward friction force applied by the auxiliary compression spring 65 to the arc sleeve 63 increases, and the downward friction force and the upward elastic force offset a part, so that the constant force spring 6 maintains a certain degree of constant force output. When the main compression spring 64 moves down, the degree of compression of the main compression spring 64 decreases, and the upward elastic force applied by the main compression spring 64 to the arc sleeve 63 becomes smaller. Because it is moving downward, the direction of the friction force is upward and increases, and the upward friction force and the upward elastic force work together, so that the constant force spring 6 maintains a certain degree of constant force output.

[0039] like Figure 5 and Figure 6 As shown, there are multiple auxiliary compression springs 65 , and the multiple auxiliary compression springs 65 are evenly distributed around the circumference of the axis of the arc-shaped sleeve 63 .

[0040] like Figure 2 As shown, the bearing member 1 includes a support leg 11 and a support plate 12 , and the connecting plate 41 includes a connecting plate body and a slider portion, the slider portion is installed at the lower end of the connecting plate body, and the lower end of the slider portion is in contact with the upper end of the support plate 12 .

[0041] like Figure 2 As shown, there are multiple clamps 44, and the multiple clamps 44 are all installed at the upper end of the connecting plate 41. The clamps 44 include a vertical rod, a horizontal telescopic rod and an elastic top member. The horizontal telescopic rod is horizontal in length direction and is telescopic along its own length direction. The elastic top member is installed at the lower end of the horizontal telescopic rod, and the end of the elastic top member away from the horizontal telescopic rod is in contact with the decorative panel to be polished.

[0042] like Figure 2 As shown, the direction adjustment mechanism 3 includes a groove-shaped adjustment rod 1 31 and a groove-shaped adjustment rod 2 32, the length directions of the groove-shaped adjustment rod 1 31 and the groove-shaped adjustment rod 2 32 are perpendicular, the upper end side surface of the polished connecting rod 52 is in contact with the inner side surface of the groove-shaped adjustment rod 1 31, and the upper end side surface of the polished connecting rod 52 is in contact with the inner side surface of the groove-shaped adjustment rod 2 32.

[0043] like Figure 2 As shown, the lifting mechanism 2 includes a lifting connection part 1 21, a lifting connection part 22, a horizontal connecting rod 1 23 and a horizontal connecting rod 24. The lifting connection part 1 21 and the lifting connection part 2 22 are vertical in length direction, the lifting connection part 1 21 and the lifting connection part 2 22 are slidably connected, and the horizontal connecting rod 1 23 and the horizontal connecting rod 2 24 are both horizontal in length direction.

[0044] Working principle of automobile door lower decorative plate polishing equipment:

[0045] The lower door decorative panel of the automobile is detachably connected to the connecting plate 41 by a clamp 44, and then the motor 42 drives the lead screw 43 to adjust the relative position of the connecting plate 41, and at the same time adjusts the direction adjustment mechanism 3 so that the polishing wheel 51 is located directly above the lower door decorative panel of the automobile to be polished, and then the polishing mechanism 5 is lowered as a whole by the lifting mechanism 2 until the polishing wheel 51 is in contact with the lower door decorative panel of the automobile. While the polishing wheel 51 is polishing, the direction adjustment mechanism 3 is used to make the polishing wheel 51 move along the lower door decorative panel of the automobile. Due to the presence of the constant force spring 6, when the polishing wheel 51 rises and falls with the surface of the lower door decorative panel of the automobile, the pressure applied by the polishing wheel 51 to the lower door decorative panel of the automobile remains basically unchanged, and the difference in polishing time at different locations is small, which is conducive to polishing and has a good polishing effect.
