[0002] A surface grinding machine is a device used to process the surface of parts to meet the requirements of high-precision flatness and parallelism. It is mainly used for the finishing of metal or non-metal materials, such as steel, cast iron, ceramics, glass, etc., to remove burrs, oxide layers or other impurities on the material surface, improve the surface finish, and achieve the dimensional accuracy required by the design. Surface grinding machines are widely used in fields such as mechanical manufacturing, mold processing, aerospace, and precision instrument manufacturing, and are one of the important tools for achieving high-precision processing.

[0003] Some surface grinding machines complete surface grinding by having the workpiece pass through the grinding abrasive belt under the pressing and fixation of rubber rollers. However, when grinding small-sized workpieces, due to the excessive distance between the centers of the fixation rubber rollers and the abrasive belt shaft, and the small size of the workpiece, when the workpiece contacts the grinding abrasive belt, the fixation rollers cannot press on the workpiece, resulting in the workpiece being bounced off as soon as it touches the abrasive belt, thus making it impossible to be used normally.

A workbench 2 is arranged on the machine base 1, a conveyor belt 3 is arranged on the workbench 2, and an auxiliary device 4 is arranged on the upper surface of the workbench 2. The auxiliary device 4 includes a fixed block 401, a connecting plate 402, a connecting piece 403, a rubber roller 404, a second rotating shaft 405, a second motor 406, a stabilizing roller 407 and a second fixed shaft 408. The fixed block 401 is fixedly connected to the upper surface of the workbench 2, the connecting plate 402 is fixedly connected to the upper surface of the fixed block 401, the connecting piece 403 is fixedly connected to the side surface of the connecting plate 402, a through hole is arranged on the side surface of the connecting piece 403, the second fixed shaft 408 is fixedly connected to the side surface of the connecting piece 403, the stabilizing roller 407 is rotatably connected to the cylindrical surface of the second fixed shaft 408. The conveyor belt 3 drives the workpiece on its surface to move under the drive of the motor. When a general-sized workpiece contacts the abrasive belt 7, it will be pressed under the combined action of the rubber roller 404 and the stabilizing roller 407. When the workpiece size is small, it will be extruded by the stabilizing roller 407, so as to prevent the workpiece from being bounced off when contacting the abrasive belt 7.

[0024] The second motor 406 is fixedly connected to the inner side surface of the machine base 1, the second rotating shaft 405 is fixedly connected to the output end of the second motor 406, the second rotating shaft 405 passes through the through hole on the side surface of the connecting piece 403, and the rubber roller 404 is fixedly connected to the cylindrical surface of the second rotating shaft 405. The rubber roller 404 is above the conveyor belt 3, and the bottom of the rubber roller 404 is at the same height as the bottom of the stabilizing roller 407. The surface of the stabilizing roller 407 is provided with a rubber layer.

[0025] The surface of the driving wheel 9 is provided with an abrasive belt 7, the other end of the abrasive belt 7 is tightly sleeved on the surface of the driven wheel 5. The stabilizing roller 407 is between the bottom of the abrasive belt 7 and the bottom of the rubber roller 404, and the stabilizing roller 407 does not contact the surface of the abrasive belt 7.

[0026] The inner side surface of the machine base 1 is fixedly connected with a first fixed shaft 6, and the driven wheel 5 is rotatably connected to the cylindrical surface of the first fixed shaft 6.

[0027] The inner side surface of the machine base 1 is fixedly connected with a first motor 8, the output end of the first motor 8 is fixedly connected with a first rotating shaft 10, the cylindrical surface of the first rotating shaft 10 is fixedly connected with a driving wheel 9, and the driving wheel 9 is directly above the driven wheel 5.

[0028] Working principle: When in use, place a workpiece with a smaller size on the conveyor belt 3. The conveyor belt 3 will drive the workpiece to move. When the workpiece moves to the bottom of the rubber roller 404, it is pressed tightly. Subsequently, the workpiece continues to move with the conveyor belt 3 to the bottom of the stabilizing roller 407, making the workpiece pressed tightly by both the rubber roller 404 and the stabilizing roller 407. Since the size of the workpiece is small, when the rubber roller 404 releases the pressing on the workpiece, the workpiece has not yet moved to the bottom of the abrasive belt 7. However, at this time, the workpiece is still pressed tightly by the stabilizing roller 407. Therefore, when the workpiece moves to the bottom of the abrasive belt 7, the workpiece is pressed tightly by the stabilizing roller 407, preventing the workpiece from being bounced off by the abrasive belt 7, thus solving the problem that the equipment is bounced off when grinding small workpieces.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
