When the first moving component 350 moves linearly, it will drive the flipping component 360 to rotate in a certain direction.

[0048] The flipping assembly 360 is provided with a clamping mechanism 100 for clamping and fixing the processed metal casting.

[0049] The piston assembly 390 is provided with a piston rod 391, and a rubber piston 392 is installed at one end of the piston rod 391. The rubber piston 392 is located inside the piston cylinder 393.

When the hydraulic telescopic rod 310 is started, it will drive the first moving component 350 to move linearly in a certain direction through the connecting block 330 and the first Z-shaped connecting plate 340. When the first moving component 350 moves linearly in a certain direction, the rack plate 352 on the first moving component 350 will mesh with a gear 363 on the flipping component 360, thereby causing the flipping component 360 to rotate in a certain direction. When the flipping component 360 rotates in a certain direction, another gear 363 on the flipping component 360 will mesh with the rack plate 352 on the second moving component 380, thereby causing the second moving component 380 to move linearly in a certain direction. When the first moving component 350 and the second moving component 380 move linearly in a certain direction, the piston assembly 390 will move like a piston.

[0056] The flipping assembly 360 is provided with a rotating plate 361. A connecting shaft 362 is installed on the end walls of both ends of the rotating plate 361.

[0057] The clamping mechanism 100 is composed of a dot matrix flexible clamp 110, a Z-shaped mounting plate 120 and a double piston double-acting cylinder 130. Both ends of the double piston double-acting cylinder 130 are equipped with Z-shaped mounting plates 120. The dot matrix flexible clamp 110 is installed on the outer wall of the Z-shaped mounting plate 120.

[0059] Working Principle: When in use, after connecting to an external power source, if the operator needs to clamp the metal casting to be processed, the operator places the metal casting at a certain position on the top of the support frame 200. The operator then activates the double-piston double-acting cylinder 130 on the clamping mechanism 100, causing the dot-matrix flexible clamp 110 on the clamping mechanism 100 to clamp the metal casting. Next, the operator activates the hydraulic telescopic rod 310. The extension and retraction of the hydraulic telescopic rod 310 causes the first moving component 350 to move linearly in a certain direction. This linear movement causes the flipping component 360 to rotate in a certain direction. The rotation of the flipping component 360 causes the metal casting clamped by the clamping mechanism 100 to rotate in a certain direction. Thus, this invention allows for the flipping of the clamped metal casting, facilitating the machining of different outer walls of the metal casting and improving the processing efficiency. The rotation of the flipping component 360 in a certain direction... This causes the second moving component 380 to move linearly in a certain direction. When the first moving component 350 and the second moving component 380 move linearly in a certain direction, the piston assembly 390 will move like a piston. When the piston assembly 390 moves like a piston, it will inflate the tank 321 on the spray assembly 320. When a certain amount of gas is filled into the tank 321, the gas pressure inside the tank 321 will increase to a certain value, and the pressure relief valve on the outlet end of the tank 321 will automatically open, allowing gas to flow into the tank 321. The gas is transported through the conveying pipe to the hollow blow plate 322 and ejected from the blow holes on the hollow blow plate 322. The gas ejected from the blow holes blows the debris on the top of the support frame 200 onto the inclined chip guide plate 210. The inclined chip guide plate 210 guides the debris into the debris collection tank 420 for collection. Thus, this utility model can automatically clean the debris that falls on the top of the support frame 200 during the processing of metal castings, eliminating the need for manual cleaning of the debris on the top of the support frame 200 and reducing labor intensity.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
