Description

Technical Field

[0001] The present application relates to the technical field of polishing machines, and in particular to a switch door of a polishing workbench. Background Art

[0002] After the valve is processed, the surface of the valve is relatively rough due to the problem of processing accuracy. In order to make the appearance of the valve smoother and flatter and avoid the burrs generated in the production process that affect the coordination between the valve and other parts, the staff will use a polishing machine to grind and polish the surface of the valve after production to make the surface of the part smoother. The operating platform for polishing is the polishing workbench, which usually meets the functions of object bearing, power integration and dust collection.

[0003] In the existing technology, in order to ensure the efficiency and practicality of dust collection, the workbench will set up guard plates on both sides of the workbench surface. Without changing the motor power, the air flow area is reduced, the air flow rate is increased, and the suction force of the dust is improved. However, it will reduce the operating space, making it inconvenient to operate, and it cannot be dynamically adjusted according to the size of the dust. Therefore, there is room for improvement. Summary of the Invention

[0004] To address the above-mentioned problems, the present application proposes a door opening and closing system for a polishing workbench. The door opening and closing system comprises movable sliding door guards disposed on both sides of the workbench surface, and a fully retractable rolling shutter door system. The sliding door guards cooperate with the door opening and closing system to form an open workbench surface with a variable opening size, thereby achieving adaptation to the object being polished and adjustment of the size of the operating space. The door opening and closing system for the polishing workbench is specifically implemented through the following technical solutions:

[0005] A switch door for a polishing workbench comprises: a sliding door guard plate and a rolling door, wherein the sliding door guard plate is provided with two leaves, and the sliding door guard plates are movably provided on both sides of the workbench surface; the rolling door is provided on the workbench and movably provided between the two sliding door guard plates, and the rolling door and the sliding door guard plates form a workspace with an opening on one side and an adjustable opening size.

[0006] It is further configured that limiting track flanges are provided on both sides of the workbench body, the sliding door guard plate is tightly attached to the outer side of the limiting track flange, and the sliding door guard plate is connected to a first connecting block corresponding to the position of the limiting track flange by fasteners, and the first connecting block is provided with a groove adapted to the limiting track flange, and the sliding door guard plate can be movably arranged on both sides of the workbench body along the extension direction of the limiting track flange through the limiting cooperation with the limiting track flange through the groove. Through this configuration, the sliding door guard plate limit movement is set on both sides of the workbench body, thereby realizing the switchable function of the sliding door guard plate.

[0007] It is further configured that the rolling door includes a shell, a motor, a rolling door plate and a rotating shaft. The motor and the rotating shaft are transmission-connected, and both the motor and the rotating shaft are arranged inside the shell. The end of the rolling door plate is connected to the rotating shaft, and the motor drives the rotating shaft to rotate forward or reverse to control the folding and lowering of the rolling door plate. Through this configuration, the rolling door can be folded and lowered, and the size of the workbench opening can be changed to achieve the adjustment of the air flow rate.

[0008] It is further provided that a second connecting block is provided at the bottom end of the rolling door panel, the second connecting block is connected to the rolling door panel by a fastener, and a limiting groove is provided on the second connecting block, and the limiting groove is clamped on the outer edge of the sliding door guard plate and can slide along the extension direction of the outer edge of the sliding door guard plate. Through this setting, the gap between the rolling door and the sliding door guard plate is reduced, making the overall structure tighter.

[0009] It is further provided that the shell is provided with an inspection port corresponding to the projection position of the rotating shaft and the motor inside the shell, and a detachable closed guard plate is provided outside the inspection port. Through this provision, it is convenient to inspect the parts inside the shell.

[0010] It is further configured that the rolling door panel includes a plurality of door strips, and the door strips are connected by hinges to form a rolling door panel that can be rolled up. Through this configuration, the rolling door panel can be rolled up and retracted, making the overall volume smaller and more compact.

[0011] In summary, the opening and closing door of the polishing workbench is achieved by arranging movable sliding door guards on both sides of the workbench surface, and arranging a rolling door system that can be completely retracted, which cooperates with the sliding door guards to form a workbench surface with a variable opening size and an open one side. On the one hand, by changing the size of the opening, the air path is reduced to increase the air flow speed and the suction force, which can better absorb dust and debris with heavier weight. On the other hand, if the polished object itself is large in size and the workbench needs to have a larger operating space, the size of the opening can be adjusted to achieve the adjustment of the size of the operating space.
