Door closing mechanism for hydrocarbon cleaning machine

Abstract

The invention discloses a door closing mechanism for a hydrocarbon cleaning machine. The door closing mechanism comprises a machine body, a furnace door, a moving mechanism and pressing mechanisms. The machine body comprises a door frame and a sealing structure arranged on the door frame, the door frame is of a plate-shaped structure with an opening, and the furnace door is located on the door frame. The moving mechanism comprises guide rails fixed on the door frame, a frame sliding along the guide rails and a first linear driving mechanism which drives the frame to move, the frame is located on the furnace door, and the frame is connected with the furnace door through a pin hole structure. Each pressing mechanism comprises a second linear driving mechanism, a connecting plate, a sliding rod and a cam, wherein sliding rails are arranged on the frame, the two ends of the sliding rod slide along the sliding rails, the second linear driving mechanism is fixed on the frame and drives the connecting plate to move, the sliding rod is fixed on the connecting plate, the cam is arranged on the connecting plate in a rotating mode, and the cam butts against the furnace door. By reasonably arranging the frame, the moving mechanism and the pressing mechanisms, the furnace door of the hydrocarbon cleaning machine can keep airtight under the positive pressure, ordinary pressure and negative pressure, and solvent leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of hydrocarbon cleaning machines, in particular to a door closing mechanism of a hydrocarbon cleaning machine. Background technique [0002] The hydrocarbon cleaning machine is a workpiece cleaning device, which uses the mechanical shock force with strong ultrasonic penetration to impact the surface of the workpiece, and combines the chemical decontamination effect of the hydrocarbon cleaning agent to perform comprehensive cleaning in a vacuum state, so that the surface of the workpiece and the blind hole , Clean the slits. [0003] In the prior art, the furnace door opening and closing structure of the hydrocarbon cleaning machine is generally an opening and closing cylinder structure or a 30° inclined track pressing structure. If the workpiece is not immersed in the hydrocarbon cleaning machine and the body is under normal pressure or negative pressure, the above-mentioned furnace door opening and closing...

AI Technical Summary

Problems solved by technology

If the workpiece is not immersed in the hydrocarbon cleaning machine and the body is under normal pressure or negative pressure, the above-mentioned furnace door opening and closing structure is more widely used; if the workpiece is immersed in the hydrocarbon cleaning machine, the pressure inside the body will increase, and the furnace door will produce The force will cause a gap between the furnace door and the door frame, and the solvent in the machine will leak out from the gap, wasting resources and polluting the environment
