Description

Technical Field

[0001] This utility model relates to a cleaning machine fixture, specifically a CNC high-pressure cleaning machine fixture. Background Technology

[0002] CNC high-pressure cleaners are mainly divided into two application forms: single-machine structure and combined structure. In the single-machine structure, after the CNC high-pressure cleaner finishes cleaning the workpiece, it is necessary to manually blow-dry it or unload the workpiece and move it to a vacuum drying equipment or other drying equipment for drying. If required, additional cold air cooling operation is also required. This structure is suitable for production lines with a small variety of workpieces to be cleaned. The combined structure connects the CNC high-pressure cleaner, vacuum dryer, cold air equipment and other equipment in series through roller conveyors to form a fully automated cleaning production line. This structure is suitable for production lines with mixed production of multiple products.

[0003] To prevent workpiece displacement due to high-pressure water jets during cleaning, which could lead to incomplete cleaning, a CNC high-pressure washer fixture is typically used to position and clamp the workpiece before cleaning begins. In existing technology, the CNC high-pressure washer fixture usually includes a sub-plate and a mother plate. The sub-plate independently loads the workpiece and is mounted on the mother plate inside the CNC high-pressure washer. During cleaning, the CNC high-pressure washer controls the mother plate to rotate, thereby rotating the workpiece and ensuring that every surface of the workpiece is cleaned.

[0004] Currently, the subplates of CNC high-pressure cleaning machine fixtures are all manually clamped. This type of fixture requires manual loading, unloading and clamping operations, which prolongs the work cycle. In production lines with a small variety of workpieces to be cleaned, the impact is small. However, in multi-variety mixed production scenarios, this type of fixture cannot achieve full automation of CNC high-pressure cleaning, which restricts the improvement of production efficiency.

[0005] Chinese patent CN220836895U discloses a tooling fixture for a high-pressure cleaner, including a drive mechanism, a main board, and several auxiliary plates. The auxiliary plates support and position the workpiece to be cleaned. The main board is equipped with detection components and mounting slots corresponding to the auxiliary plates. The drive mechanism drives the auxiliary plates to rotate 90 degrees relative to the main board, rotatably mounting the auxiliary plates onto the main board. This allows the high-pressure cleaner to clean all sides of the workpiece in one operation. This solution only optimizes the cleaning stage and improves the cleaning efficiency of the workpiece, but it still does not solve the problem of long cycle times caused by the need for manual loading, unloading, and clamping operations during the cleaning process, making it impossible to achieve full automation of CNC high-pressure cleaning. Utility Model Content

One mother plate air inlet communicates with the space at the top of the piston plate in each second pressing cylinder 7, and the other mother plate air inlet communicates with the space at the bottom of the piston plate in each second pressing cylinder 7.

Between the rollers, each of the three bases has an air inlet on its top. The three air inlets correspond to the air inlets of the two air inlet channels 4 and the air detection port on the sub-plate 1, respectively. Each of the three air inlets is equipped with a retractable air tube, the outer diameter of which is adapted to the aperture of the air inlet channel 4 and the air detection port. The two air inlets corresponding to the air inlets of the two air inlet channels 4 are connected to an external air compressor through two air inlet pipes. Each of the two air inlet pipes is equipped with a solenoid valve. The air inlet corresponding to the air detection port is connected to an external air detection device. The retractable air inlet pipe, the solenoid valve, and the external air detection device are all electrically connected to an external controller.

[0043] This embodiment describes the working principle of an automated production line for CNC high-pressure cleaning machines:

[0044] Before the cleaning process begins, the workpiece to be cleaned is correctly placed on the sub-plate and positioned using positioning pins 10. Sensors at the production line loading point automatically identify the workpiece. An external controller selects the appropriate cleaning program based on the identification results and then transports the sub-plate to the high-pressure washer station via roller conveyor 12. Once in position, a lifting device and transfer mechanism move the sub-plate onto the mother plate inside the high-pressure washer. Roller conveyor 12 and baffles 13 on the mother plate adjust and position the sub-plate. Once the position is correct, the retractable inflation tubes in the two inflation ports extend and insert into the two air inlets. Then, a solenoid valve controls inflation into another air inlet channel 4 and another air inlet on the mother plate. Gas flows from another air passage into the top of the piston plate of each first clamping cylinder 3 and into the bottom of the piston plate of each second clamping cylinder 7. At this time, the pressure tongue of each first clamping cylinder 3 moves downward to clamp the workpiece to be cleaned as the pressure at the top of the piston plate increases. At the same time, the clamping plate of each second clamping cylinder 7 moves upward to clamp the bottom of the pressure plate on both sides of the sub-plate and the integrated support frame 8 as the pressure at the bottom of the piston plate increases, thus completing the fixation of the sub-plate and the mother plate. The clamping state of the first clamping cylinder 3 and the second clamping cylinder 7 is confirmed by an external air detection device connected to the air detection port on the sub-plate 1 and a signal is given. After the confirmation signal is correct, the cylinder door of the high-pressure cleaner is automatically closed and high-pressure cleaning begins.

[0045] The high-pressure cleaning pressure is adjustable from 5-50 MPa. It automatically selects the appropriate spray gun according to the different structures and hole characteristics of the workpiece to be cleaned, so as to more effectively perform high-pressure cleaning on the workpiece to achieve the cleaning requirements. At the same time, the low-pressure high-flow spray continuously and thoroughly rinses the workpiece. The cleaning pressure is 0.8 MPa. It can also be turned on or off through the program of the external controller. After cleaning, the spray gun returns to the original position. The cleaned workpiece is quickly flipped over, and the fixed air pipe cuts the water off the cleaned workpiece.

[0046] After the water cutting is completed, the mother plate returns to its original position. The external controller's program controls the solenoid valve to pressurize an air intake channel 4 and a mother plate air inlet. This causes the gas to flow from one air channel into the bottom of the piston plate of each first clamping cylinder 3 and into the top of the piston plate of each second clamping cylinder 7. At this time, the pressure tongue of each first clamping cylinder 3 moves upward as the pressure at the bottom of the piston plate increases, releasing the workpiece to be cleaned. Simultaneously, the clamping plate of each second clamping cylinder 7 moves downward as the pressure at the top of the piston plate increases, separating the daughter plate from the bottom of the pressure plates on both sides of the integrated support frame 8, thus completing the process. The sub-board and motherboard are separated, and then the sub-board is sent out of the high-pressure washer by the transfer mechanism and lowered by the lifting device on roller conveyor 12. The sub-board is placed on roller conveyor 12 and transported to the hot air blowing chamber. After the external controller detects that it is in position, roller conveyor 12 stops running, the cylinder door of the hot air blowing chamber closes and the hot air blowing begins. The temperature and time of the hot air blowing can be adjusted and set. After the time is up, the cylinder door automatically opens, and the sub-board is then transported through roller conveyor 12 to the large-screen vacuum drying chamber for drying. After drying, the sub-board is transported to the unloading position and the system stops after the detection is in position.
