The support arm 212 is connected to a tilting gantry 211. The air hammers 213 move back and forth and are fixed by loosening and tightening the moving column 216. The air hammers 213 move left and right and are fixed by loosening and tightening the clamping plate 215. The air hammers 213 move up and down by tilting the tilting gantry 211, which in turn drives the support arm 212 to tilt up and down. The control cabinet 1 controls the tilting gantry 211 to tilt.

[0021] Preferably, the air hammer is adjustable in left-right, forward-backward, and up-down positions, and can cover a platform of at least 1500mm*1100mm. It can be used for sandblasting of different types of products through quick tooling switching. The moving column 216 is tightened or loosened by the first screw 217. When the first screw 217 is loosened, the air hammer 213 moves forward and backward along the hammering arm 214; when the first screw 217 is tightened, the air hammer 213 is fixed to the hammering arm 214. The clamping plate 215 is tightened or loosened by the second screw 218. When the second screw 218 is loosened, the air hammer 213 moves left-right along the support arm 212; when the second screw 218 is tightened, the air hammer 213 is fixed to the support arm 212.

[0022] Preferably, the air hammer can be controlled in any combination, the hammering force of the air hammer is adjustable, and the hammering air pressure can be displayed in the control cabinet.

[0029] Each workpiece has a separately designed tooling clamping mechanism, and the sand removal platform can be made universal by changing the tooling clamping mechanism for different workpieces. Preferably, the tooling base plate (tooling clamping mechanism) and the equipment working platform 22 have a standard positioning key interface and multiple universal screw holes. The tooling clamping mechanism can be disassembled and assembled by removing and installing bolts, and the time is controlled to about 15 minutes.

[0030] Preferably, the tooling base plate 227 is provided with lifting rings 228 for lifting and replacing the tooling.

The second airbag 231 is controlled to move up and down by an air valve.

[0032] When the pneumatic hammer 213 strikes, the lifting mechanism rises to support the work platform 22, preventing the downward hammering force from acting on the support mechanism.

The vibration motor 236 is connected to the base 23 via a screw. The vibration motor 236 vibrates up and down to drop sand, performing elliptical trajectory vibration on the vertical plane.

[0036] Preferably, both the first airbag 221 and the second airbag 231 are provided with an interface 24 at their bottom, through which the first airbag 221 and the second airbag 231 can be individually adjusted and controlled.

[0037] Preferably, the polyurethane pad 224 is disposed in the middle of the tooling base plate 227 to buffer the vibration of the work platform 22.

[0038] Preferably, the tooling base plate 227 is provided with lifting rings 236 for lifting and replacing the tooling.

[0039] Preferably, such as Figure 6 As shown, the work platform 22 is provided with a positioning key interface 229. The tooling base plate 227 is positioned on the work platform 22 through the positioning key interface 229, and then the tooling base plate 227 is fixed on the work platform 22 by bolts.

[0040] The sand removal process of the above-mentioned high voltage electrical appliance shell sand removal device is as follows: the workpiece is placed on the fixture 222 for positioning by hand → start the two-hand button → close the loading door → the fixture 222 clamps the workpiece → the flip gantry 211 drives the air hammer 213 to flip to the hammering position → the air hammer 213 hammering timer starts (the platform lifting mechanism rises) → the air hammer 213 hammering ends (the platform lifting mechanism descends) → the workpiece is subjected to up and down sand removal → the workpiece sand removal stops → the workpiece clamping airbag (first airbag 221) is released → (4) the flip gantry 211 drives the air hammer 213 to flip to the original position → the loading door is opened → the workpiece is taken out from the work station by hand.
