Firstly, regarding to the aspect of controlling the sanding force, what is needed to be added here is that the existing sanding force all adopts a rigid constant force, and the rigid constant force cannot automatically adjust the sanding force according to the unevenness and the depth of the surface to be sanded, so that there may be a problem of sand leakage or sand passing. Specifically, the method comprises the following steps:
the polishing device comprises a polishing mechanism and a pressure control mechanism;
the polishing mechanism is used for polishing the surface to be polished;
the pressure control mechanism is connected with the grinding mechanism and comprises a compression spring, and the compression spring is precompressed by a section of stroke so that the grinding mechanism always has elastic force for flexibly adjusting sanding force.
The technical effect analysis that above-mentioned grinding device can realize is as follows:
the compression spring is precompressed for a certain stroke, so that the grinding mechanism always has the elastic force for flexibly adjusting the sanding force. The sanding force provided by the compression spring is a flexible sanding force, and the flexible sanding force is compared with the existing rigid constant force, so that the sanding force can be automatically adjusted according to the unevenness and the depth of the surface to be sanded, and the problems of sand leakage and sand passing can be effectively avoided.
With regard to the specific structure of the pressure control mechanism 100, please refer to fig. 2, the pressure control mechanism 100 is provided with a guide assembly 130, and specifically, the guide assembly 130 includes a main yoke plate 131, a guide sleeve 132 installed in the main yoke plate 131, and a guide shaft 133 installed in the guide sleeve 132. In a specific working process, the main link plate 131 is connected with the sanding device through the large link plate 120, and the movement of the pressure control mechanism 100 is influenced by the contact degree between the bottom plate 250 of the sanding mechanism 200 and the surface to be sanded, so that the guide sleeve 132 in the main link plate 131 and the guide shaft 133 installed in the guide sleeve 132 move up and down, and therefore, the whole sanding device can always run along a preset track.
In addition, in order to realize the connection between the pressure control mechanism 100 and the grinding mechanism, the pressure control mechanism 100 further comprises a connecting plate 140 disposed at the lower part of the compression spring 110, the connecting plate 140 is L-shaped, and comprises a transverse connecting member abutting against the lower part of the compression spring 110 and a longitudinal connecting member (directly or indirectly) connected with the grinding mechanism, wherein a bolt fastening structure is disposed at the lower surface of the transverse connecting member, and the bolt fastening structure can adjust the pre-pressure between the transverse connecting member and the compression spring 110. The left side of the longitudinal connector is provided as a connection surface, which is fixed to the frame body 500. The reader is referred to fig. 2 for a specific structure of the link plate 140.
In addition, in consideration of the poor effect of applying the flexible adjusting force only at one position of the grinding mechanism, in the present embodiment, the pressure control mechanism 100 is provided with two guide assemblies 130, and the two guide assemblies 130 are connected to each other by an upper link plate 150 fitted around the guide shaft 133 for realizing the synchronous movement.
The pressure control mechanism 100 flexibly adjusts the sanding force in a mechanical control manner, and in order to further optimize the effect of flexibly adjusting the sanding force, the polishing device in the embodiment is further provided with an electric pressure control module which adjusts the sanding force in an electric control manner. Specifically, the electric pressure control module determines the contact degree between the polishing device and the surface to be polished according to the torque of the servo motor 410 of the power mechanism 400. It should be noted that, the polishing resistance may be applied to the polishing device during the process of polishing the surface to be polished, the servo motor 410 (belonging to the power mechanism 400, where the power mechanism 400 will be described later) actively adjusts the torque according to different polishing resistances to adapt to different resistances, and the different torques represent different contact degrees between the bottom plate 250 of the polishing mechanism 200 and the surface to be polished. According to the principle, the effect of flexibly adjusting the sanding force can be further optimized through the electric pressure control module.
The above states the effect of the flexible sanding force, and the following discusses the specific structure of the sanding mechanism 200 for implementing the sanding process, and referring to fig. 3, the sanding mechanism 200 includes: an eccentric shaft 210 having an axis perpendicular to the polishing surface and for realizing eccentric operation; an eccentric 220 connected to an end of the eccentric shaft 210 facing the grinding surface and having an inner cavity; a bearing 230 installed in the inner chamber; a small rotation shaft 240 having a top portion extended into the bearing 230 and capable of performing rotation and eccentric operation by itself; and a bottom plate 250 connected with the lower part of the small rotating shaft 240, wherein the lower surface of the bottom plate 250 facing the polishing surface is used for attaching abrasive sheets, and the bottom plate 250 is provided with a dust suction hole 251 and a notch 252 for positioning.

In addition, in order to ensure a good dust suction effect, the bottom plate 250 is provided with a dust suction hole 251, and the dust suction hole 251 can be positioned well. Specifically, similar to the principle of the notch 252, since the relative position of the sensing piece 253 and the dust suction hole 251 is fixed, the position of the dust suction hole 251 is naturally positioned after the position of the sensing piece 253 is positioned. Regarding the effect of the dust suction hole 251 on the bottom plate 250, specifically: staff (or trade sand piece mechanism) can carry out effective location according to dust absorption hole 251 when attached sand piece to at attached sand piece in-process, the hole site on the sand piece can realize the alignment one by one with dust absorption hole 251, and the dust that the sand light in-process produced can get into inside bottom plate 250 through dust absorption hole 251, thereby guarantees good dust absorption.
