Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, specifically relating to a wind knife cleaning machine for anti-collision beams. Background Technology

[0002] The existing cleaning process for automotive anti-collision beams is: pre-degreasing → degreasing → water washing → acid washing → water washing → drying. Its disadvantages are: first, if the waste liquid from acid washing is not properly treated, it will pollute the environment; second, the process is long and the cleaning efficiency is low. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of environmental pollution and low cleaning efficiency in the existing cleaning process for automobile anti-collision beams, and to provide an air knife cleaning machine for anti-collision beams.

[0004] A wind-knife cleaning machine with a crash beam includes a frame, an X / Y / Z three-axis servo motion mechanism, a crash beam fixing frame, a loading cylinder, a loading door, a side chip blowing device, an upper chip blowing device, a side chip blowing fan, an upper chip blowing fan, an aluminum chip storage box, and a closed shell. The upper part inside the closed shell is a drying chamber. The X / Y / Z three-axis servo motion mechanism is mounted on the frame. The two ends of the crash beam fixing frame are slidably mounted on the slide rails via guide blocks. The telescopic end of the loading cylinder is connected to the crash beam fixing frame, and the other end of the loading cylinder is fixed to the frame. The loading cylinder can push the crash beam fixing frame out or pull it in.

[0005] The side-blowing chip removal device consists of a blower pipe and a cylinder. The cylinder body is fixed to the frame via a base. The telescopic rod of the cylinder has a first connecting block at its head. A second connecting block is fixed to the bottom of the blower pipe. The second connecting block is fixed together with the first connecting block. The inlet end of the blower pipe is connected to the side-blowing chip removal fan via a first flexible hose. The cylinder can drive the blower pipe to move forward or retract.

[0006] The second connecting block is fixed to the first connecting block by a self-locking buckle.

[0007] The base includes a lower base and an upper base. The lower base is fixed to the frame by guide rails and bolts. The upper base has arc-shaped grooves on both sides. The upper base is fixed to the lower base by bolts passing through the arc-shaped grooves. The bottom of the blower pipe is fixed to the upper base. In this way, the angle of the blower pipe can be adjusted by the arc-shaped grooves.

[0008] The aforementioned chip blowing device consists of a third connecting block and a П-shaped blower head. The П-shaped blower head is connected to the X / Y / Z three-axis servo motion mechanism through the third connecting block. The П-shaped blower head can move arbitrarily in the X / Y / Z three-dimensional space. The opening of the П-shaped blower head faces downward. The inner side of the П-shaped blower head has an air outlet. The П-shaped blower head is connected to the chip blowing fan through a second flexible hose.

[0009] The aluminum shavings storage box is located at the bottom of the frame, and the upper part of the storage box has a funnel. The funnel is located below the anti-collision beam fixing frame. The residual oil and aluminum shavings blown off by the anti-collision beam can fall into the aluminum shavings storage box through the funnel. The aluminum shavings storage box has a screen, which can retain aluminum shavings on the screen, and the residual oil flows into the aluminum shavings storage box.

[0010] The side-blowing chip blower and the top-blowing chip blower are fixed at the bottom of the frame and located on both sides of the aluminum chip storage box.

[0011] The four sides and top of the frame are enclosed by a closed shell. An upper part door is installed at the part inlet of the anti-collision beam on the frame. During operation, the upper part door is closed.

[0012] The working process of this invention: In the initial state, the loading door is open, the loading cylinder is activated, the loading cylinder pushes out the anti-collision beam fixing frame, and the anti-collision beam to be cleaned is installed on the anti-collision beam fixing frame manually. Then, the loading cylinder retracts, pulling the anti-collision beam to be cleaned into the cleaning machine, and the loading door is closed.

[0013] Then, the cylinder of the side-blowing device moves inward, inserting the blower pipe into the anti-collision beam to be cleaned, with the shape and size of the blower pipe matching the inner opening of the anti-collision beam to be cleaned.

[0014] Simultaneously, the side-blowing chip blower, the top-blowing chip blower, and the X / Y / Z three-axis servo motion mechanism are activated. The blower pipe of the side-blowing chip blows air into the anti-collision beam to be cleaned, blowing out the residual oil and aluminum chips inside the anti-collision beam from the other end, which fall into the aluminum chip storage box through the funnel. The П-shaped blower head of the top-blowing chip blows air from one end of the blower pipe along the longitudinal direction of the anti-collision beam to be cleaned to the other end, blowing off the residual oil and aluminum chips on all four sides of the anti-collision beam. The blown-off residual oil and aluminum chips fall into the aluminum chip storage box through the funnel.

[0015] After cleaning, the side and top chip blowing devices return to their original positions. The cylinder of the side chip blowing device pulls the air pipe out of the cleaned anti-collision beam. The X / Y / Z three-axis servo motion mechanism drives the top chip blowing device back to its initial position. The upper part door is opened, and the upper part cylinder pushes the anti-collision beam fixing frame out of the cleaning machine. The cleaned anti-collision beam is then manually removed, and the next cycle operation is performed.

[0016] Beneficial technical effects of the present invention: This invention utilizes a side-blowing device and an upper-blowing device to clean automotive anti-collision beams using air blowing. The airflow from the side-blowing device and the upper-blowing device acts like an air knife, removing stains, residual oil, and aluminum shavings from the inside and surface of the automotive anti-collision beam. It eliminates the need for acid washing, thus preventing environmental pollution, and the cleaning efficiency is high due to the single air blowing process. Attached Figure Description
