Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting, in particular to a sandblasting device for cast iron parts. Background Art

[0002] Sandblasting refers to a processing method in which a material is sprayed at high speed on the surface of a workpiece to grind the surface of the workpiece. Generally, cast iron parts are mostly cast in a casting sand box. The surface of the workpiece is relatively rough after molding and needs to be polished. In addition, due to the complex structure of some workpieces, they are usually sandblasted manually with a handheld spray gun. Cast iron parts are heavy in material, resulting in a large total weight of the molded workpiece. When sandblasting, users mostly manually move and adjust the position of the workpiece to expose the surface of the workpiece in various places, thereby sandblasting the workpiece, which consumes energy, has low efficiency, and is relatively inconvenient.

[0023] Embodiment 1

[0024] like Figure 4 As shown, in this embodiment, one end of any threaded push rod 320 is fixedly connected to a rubber head 321 .

[0025] In this embodiment, the threaded push rod 320 can contact the surface of the workpiece through the rubber head 321, and the friction between the threaded push rod 320 and the surface of the workpiece can be increased through the rubber head 321.

[0026] like Figure 3-4 As shown, in this embodiment, the adjustment mechanism 400 includes a rotating plate 410, a rotating hole 201 is opened on the top surface of the glass cover 200, and the rotating plate 410 is rotatably sleeved inside the rotating hole 201, a fixed plate 430 is fixedly connected to the bottom surface of the rotating plate 410, and a connecting plate 431 is rotatably connected to the bottom end of the fixed plate 430, one end of the connecting plate 431 is fixedly connected to one end of the frame 310, a U-shaped frame 420 is fixedly connected to the top surface of the glass cover 200, and a motor box 421 is fixedly connected to the top surface of the U-shaped frame 420, a stepping motor is arranged inside the motor box 421, and the motor shaft of the stepping motor is fixedly connected to the center of the top surface of the rotating plate 410.

[0027] In specific implementation, when in use, the user puts the workpiece into the frame 310 and fixes it with the threaded push rod 320. The user can then start the stepper motor to drive the rotating plate 410 to rotate, so that the rotating plate 410 drives the frame 310 and the workpiece to rotate synchronously through the connecting plate 431, thereby facilitating the user to adjust the position of the workpiece for manual sandblasting.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, the workpiece angle is controlled by providing a U-shaped bar 450 .

[0030] like Figure 3-4 As shown, in the present embodiment, two U-shaped plates 440 are fixedly connected to the bottom surface of the rotating plate 410, and a U-shaped bar 450 is slidably clamped between the two U-shaped plates 440, a box body 451 is arranged between the two arms of the U-shaped bar 450, and one end of the box body 451 on opposite sides is rotatably connected to one end of the two arms of the U-shaped bar 450 respectively, a slide plate 452 is slidably sleeved inside the box body 451, and one end of the slide plate 452 is fixedly connected to the other end of the frame body 310, a power box 460 is fixedly connected to the top surface of the rotating plate 410, and an electric hoist is arranged inside the power box 460, the electric hoist is equipped with a lifting rope 461, and one end of the lifting rope 461 passes through the bottom surface of the rotating plate 410 and is fixedly connected to a ring 462, and the ring 462 is fixedly sleeved on the top of the U-shaped bar 450.

[0031] During specific implementation, the electric hoist can release or reel in the lifting rope 461. When the workpiece is placed above the bottom plate 100, the user can start the electric hoist to release the lifting rope 461, so that the U-shaped bar 450 automatically moves downward due to its own weight, and the U-shaped bar 450 drives the other end of the frame 310 to move downward through the slide plate 452, so that the frame 310 is in an inclined state, and the frame 310 is sleeved on the workpiece on the bottom plate 100, and then the threaded support rod 320 is rotated to clamp and fix the workpiece, and then the user can start the electric hoist to reel in the lifting rope 461 to move the U-shaped bar 450 upward, so that the frame 310 is placed horizontally and the workpiece is separated from the bottom plate 100. It is convenient for users to sandblast the workpiece, and the position of the workpiece can be adjusted by starting the stepper motor to drive the rotating plate 410 to rotate. Then, the user can start the electric hoist to continue to reel in the lifting rope 461 to move the U-shaped bar 450 upward, so that the slide plate 452 pulls the other end of the frame 310 upward to tilt the frame 310, so that the bottom of the workpiece is exposed, so that the user can sandblast various parts of the workpiece, which is convenient for users to use. During the movement of the U-shaped bar 450, the slide plate 452 never leaves the inside of the box body 451, and as the position of the U-shaped bar 450 changes, the slide plate 452 adaptively slides inside the box body 451.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.

Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
