[0034] Reference Figure 1 A workpiece cleaning device according to an embodiment of this utility model includes a frame 100, a drive unit 110, and a worktable 120. The worktable includes a gantry frame 101 and a bed 102. The drive unit 110 is mounted on the top of the gantry frame 101, and the worktable 120 is mounted on the bed 102. It is understood that the drive unit 110 is equipped with a cleaning device 111, which includes a rotating plate 113 and nozzles 112. Multiple nozzles 112 are arranged circumferentially along the rotating plate 113, and the nozzles 112 extend radially outward along the rotating plate 113. It is understood that different nozzles 112 have different inner diameters, and different nozzles 112 can spray cleaning fluid at different pressures to meet the cleaning requirements of different features on the workpiece 105. Furthermore, different nozzles 112 can spray different cleaning fluids, such as detergents or water, to provide multiple cleaning steps, thereby improving the cleaning effect. Understandably, the workbench 120 includes a turntable 123 and a carrier plate 121 for mounting the workpiece 105. Both ends of the carrier plate 121 are connected to the turntable 123, allowing the turntable 123 to rotate the carrier plate 121 and change the orientation of the workpiece 105. This enables the nozzle 112 to spray cleaning fluid onto the workpiece 105 at multiple angles, adapting to the cleaning needs of various irregular features on the workpiece 105 and improving flexibility. Furthermore, the carrier plate 121 has a perforated portion 122 located at the bottom of the workpiece 105. The perforated portion 122 allows for timely drainage of cleaning fluid from the carrier plate 121 and the workpiece 105, preventing water accumulation and enabling the recycling of the cleaning fluid.

[0035] It is understood that the drive device 110 includes a first moving plate 114, a second moving plate 115, and a lifting plate 116 connected in sequence. The first moving plate 114 is slidably connected to the top of the gantry frame 101 and can move along the width direction of the bed 102. The second moving plate 115 can move on the first moving plate 114 along a horizontal plane, and the direction of movement of the second moving plate 115 is perpendicular to the width direction of the bed 102. The lifting plate 116 is slidably connected to one end of the second moving plate 115 in a vertical direction, and the rotating plate 113 is pivotally connected to the lifting plate 116, so that the rotating plate 113 and the nozzle 112 can move in both height and horizontal directions. At the same time, the lifting plate 116 is provided with a rotating mechanism 117, which is used to drive the rotating plate 113 to rotate. The rotation axis of the rotating plate 113 is perpendicular to the rotation axis of the carrier plate 121, so as to change the swing angle of the nozzle 112, so that the nozzle 112 can spray the workpiece 105 at different angles and positions, which is beneficial to improving the flexibility of the cleaning process. Understandably, the workpiece 105 cleaning equipment can achieve the cleaning of workpiece 105 by modifying the four-axis machining center and replacing its machining spindle with a cleaning device. Furthermore, the four-axis machining center is driven by a servo motor, which has excellent motion precision and fast running speed. This allows the nozzle 112 to quickly and accurately clean certain features of the workpiece 105, such as holes, grooves, and recessed inner walls, which helps to improve the cleaning effect, eliminates the need for repeated cleaning, and helps to reduce costs.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The carrier plate 121 is provided with multiple support columns 126 surrounding the outer periphery of the hollow portion 122. The support columns 126 abut against the bottom wall of the workpiece 105 to support the workpiece 105. Furthermore, a clamping cylinder 127 is provided on the side of the support column 126, and the clamping cylinder 127 is provided with a pressure block 131. The pressure block 131 can press against the wall surface of the workpiece 105 opposite to the support column 126 to clamp and fix the workpiece 105. Further, multiple positioning pins 124 and positioning rods 125 are provided on the outer periphery of the hollow portion 122. The positioning pins 124 are inserted into the positioning holes 106 of the workpiece 105 to position the workpiece 105. It can be understood that the positioning rods 125 abut against the outer peripheral wall of the workpiece 105 to provide auxiliary limiting of the workpiece 105, facilitating quick positioning when changing the workpiece 105, so that the positioning pins 124 can be quickly and accurately inserted into the positioning holes 106, which helps improve operational efficiency. It is understood that the bottom of the positioning rod 125 has an adjustment block 130, which is detachably mounted on the carrier plate 121. The adjustment block 130 has a slot, through which the installation position of the adjustment block 130 on the carrier plate 121 can be changed so that the outer peripheral wall of the positioning rod 125 can abut against the outer side wall of the carrier plate 121, and can adapt to workpieces 105 of different sizes or shapes.

[0037] Furthermore, the carrier plate 121 is provided with an adjusting rod 128, which abuts against the bottom wall of the workpiece 105, and the top of the adjusting rod 128 has a height-adjustable support block 129. It is understood that the support block 129 is threadedly connected to the adjusting rod 128, and rotating the support block 129 adjusts the height, increasing the stability of the carrier plate 121 in supporting the workpiece 105 while ensuring the workpiece 105 is placed horizontally. Moreover, when changing to workpieces 105 of different shapes, the height of the support block 129 can be adjusted for adaptation, improving usability. Further, referring to... Figure 5 Along the circumference of the workpiece 105, the adjusting rod 128 and the support column 126 are staggered, which helps to improve the adaptability to different workpieces 105.

[0038] Understandably, the bed 102 has a drain trough 103 located at the bottom of the worktable 120, which can be used to collect cleaning fluid dripping from the carrier plate 121 and the workpiece 105. Furthermore, it also includes a circulating filter device 104, which filters the cleaning fluid discharged from the drain trough 103 and sprays the clean cleaning fluid onto the workpiece 105 through a nozzle 112, achieving cleaning fluid recycling and helping to reduce costs.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
