Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning machines, in particular to a cleaning machine clamp device with multiple positioning detection functions. BACKGROUND

[0002] A high-pressure cleaning machine is a machine that uses a high-pressure plunger pump to generate high-pressure water to clean the surface of an object. It can strip and flush away dirt to clean the surface of an object. Because it uses a high-pressure water column to clean dirt, high-pressure cleaning is one of the most scientific, economic and environmentally friendly cleaning methods recognized by the world.

[0003] Currently, in order to improve cleaning efficiency, a high-pressure cleaning machine generally installs a shell part to be cleaned on multiple special tooling, and then pushes the part to be machined (installed on the clamp) into the cleaning machine for cleaning after the cleaned part is removed. However, there are certain problems and defects, the most important of which are:

[0004] 1. The clamp base plate is not accurately positioned in the cleaning machine: when the workpiece is installed on the clamp, the base plate of the clamp is pushed into the cleaning machine, and the base plate can still slide at the bottom end. Therefore, the operator must observe the position relationship of the clamp base plate on the cleaning machine feed plate during the release of the clamping plate to avoid collision and damage to the workpiece or clamp due to improper pushing.

[0005] 2. The clamping plate is not clamped: after the clamp base plate is accurately positioned in the cleaning machine, the clamp clamping button on the CNC control panel is pressed, the hydraulic cylinder support rod is extended, and the clamping plate is lifted. If the clamping plate is not clamped tightly, there may be a gap, which may cause the workpiece to be bumped, the clamping plate to move, and even affect personal safety.

[0006] 3. Inaccurate positioning of the workpiece: in mass production, human positioning errors may occur due to installation errors or positioning surface debris, resulting in reduced quality and production efficiency. SUMMARY

[0034] In summary, as the hydraulic cylinder 7 extends its push rod, the upper clamping plate 15 is mounted, and the central air outlet support rod 6 enters the second air outlet hole. The air pressure for airtightness detection on both sides of the bottom plate stop increases, and the differential pressure sensor detects the change in differential pressure signal, indicating that the bottom plate clamp is in place. Air is supplied through the central air outlet support rod 6 of the hydraulic cylinder 7, and through the clamp base plate, the detection nozzle 27 is connected to the clamp positioning surface 26. When the workpiece is accurately positioned, the detection port 28 closes, the pressure increases, and the target detection pressure is reached.
