Referring to fig. 1-4, a polishing apparatus for polishing a plurality of sections of workpieces bent in the same direction includes a worktable 1, a driving structure 2 and a first guiding structure 3 disposed on the worktable 1, and a polishing mechanism disposed above the driving structure 2.
The working table 1 is used for horizontally placing a workpiece, in this embodiment, the workpiece to be polished is a wooden workpiece formed by gluing, bending and forming, and is bent at two sides to form a three-segment structure, and the overall shape of the workpiece is U-shaped, and the workpiece is divided into a left side segment 601, a middle segment 603, a right side segment 605, a left bending segment 602 for connecting the left side segment 601 and the middle segment 603, a right bending segment 605 for connecting the right side segment 605 and the middle segment 603, and a right bending segment 604 for connecting the middle segment 603.
The first guide structure 3 is used to keep the current section of the workpiece passing through the first guide structure 3 extending in the forward direction. The driving structure 2 and the first guiding structure 3 are mutually matched, the driving structure 2 is used for driving the current section of the workpiece to move along the positive direction when the first guiding structure 3 guides the current section of the workpiece, and the first guiding structure 3 is used for driving the workpiece to rotate when the current sections of the first guiding structure 3 and the workpiece are separated, so that the next section of the workpiece is guided by the first guiding structure 3. The polishing mechanism polishes the side of the current section of the workpiece.
For the present embodiment, when the left section 601 of the workpiece passes through the first guiding structure 3, the guiding action of the first guiding structure 3 keeps the left section 601 extending in the forward direction, and the driving structure 2 drives the left section 601 to move in the forward direction, and in synchronization with this, the polishing mechanism polishes the side surface of the left section 601. When the left side section 601 moves in the forward direction until it is separated from the first guide structure 3, the driving structure 2 drives the workpiece to rotate, so that the side surface of the left bending section 602 is polished by the polishing structure until the workpiece rotates until the middle section 603 can be guided by the first guide structure 3, and the middle section 603 is driven by the driving structure 2 to move in the forward direction, and then the right bending section 604 and the right side section 605.
Next, a more detailed embodiment of the driving mechanism 2 and the first guide mechanism 3 will be described.
The driving structure 2 comprises a first driving wheel 21 and a second driving wheel 22, both of which are vertically arranged on the working table 1. The first driving wheel 21 abuts on the outer surface of the current segment of the workpiece, the second driving wheel 22 abuts on the inner surface of the current segment of the workpiece, and the first driving wheel 21 rotates at a higher speed than the second driving wheel 22. When the current section of the workpiece is guided by the first guide structure 3, the first driving wheel 21 and the second driving wheel 22 respectively abut against the outer surface and the inner surface of the current section of the workpiece, and the current section of the workpiece is driven to move along the positive direction by the friction force generated by rotation; when the current segment of the workpiece is separated from the first guide structure 3, the workpiece will rotate around the second driving wheel 22 due to the difference between the rotation speed of the first driving wheel 21 and the rotation speed of the second driving wheel 22.
The first guide structure 3 is spaced apart from the drive structure 2 in the opposite direction, and the first guide structure 3 abuts against the outer surface of the current section of the workpiece. The first driving wheel 21 and the second driving wheel 22 have a difference in rotation speed, so that the current section of the workpiece can rotate without any other external acting force, and therefore, when the first guiding structure 3 is attached to the outer surface of the current section of the workpiece, the current section of the workpiece can be prevented from rotating, so that the current section always keeps extending along the forward direction, and a guiding effect is achieved.
Taking the workpiece in the U-shape in this embodiment as an example, when the outer surface of the left section 601 of the workpiece is abutted by the first driving wheel 21 and the inner surface is abutted by the second driving wheel 22, because there is a difference in rotation speed between the first driving wheel 21 and the second driving wheel 22, when the friction force generated by the two drives the left section 601 to move in the forward direction, the workpiece always has the drive of rotating clockwise, because the outer surface of the left section 601 abuts against the first guiding structure 3, the outer surface of the left section 601 is always kept extending in the forward direction, and the polishing mechanism polishes the side surface of the left section 601. When the left side section 601 of the workpiece completely passes through the first guide structure 3 and is separated from the first guide structure 3, the workpiece rotates clockwise, the first driving wheel 21 and the second driving wheel 22 respectively abut against the outer surface and the inner surface of the left bending section 602, and the polishing structure polishes the side surface of the left bending section 602. When the workpiece is rotated counterclockwise until the outer surface of the middle section 603 abuts against the first guide structure 3, the first guide structure 3 keeps the middle section 603 extending in the forward direction, the first driving wheel 21 and the second driving wheel 22 abut against the outer surface and the inner surface of the middle section 603, respectively, and drive them to move in the forward direction, and the polishing mechanism polishes the middle section 603. The right curved section 604, the right side section 605 of the workpiece then go through the same process.
Further, the first drive wheel 21 is a drive wheel, and the second drive wheel 22 is a driven wheel. That is, the drive structure 2 can save cost on the premise that only the first drive wheel 21 has power and the difference in the rotational speed between the first drive wheel 21 and the second drive wheel 22 can be realized.
