3. Sandblasting is performed during the polishing process by pressing the contact point and cooperating with the sandblasting valve. The rust on the surface of the workpiece is removed by sandblasting, which reduces the difficulty of polishing and facilitates the subsequent welding of the workpiece. Controlling by pressing the contact point can reduce the waste of abrasive materials and save costs.

4. By setting the connecting flange and the sealing gasket, the sealing is increased when connecting the pipeline to prevent air leakage during use.

While returning to its position, the gas is pushed into the first cylinder 1 through the connecting pipe 3, so that the first piston rod 52 moves downward, driving the turning head 38 to descend and contact the workpiece, and the first rotating motor 37 is started to drive the turning head 38 to rotate and turn the workpiece. The pulley 54 is driven by the first driving motor 48 to drive the turning head 38 to move. When turning is completed, the first rotating motor 37 is driven to move to one side of the first slide rail 46 and contact the second contact 35. The connecting valve 4 is controlled to be closed by the second contact 35, and the exhaust valve 2 is controlled to open at the same time, so that the gas in the first cylinder 1 is discharged, so that the first piston rod 52 drives the turning head 38 to return to its position, and the surface treatment of the workpiece is completed;

In order to remove rust from the surface, as shown in FIG1 , a fixing bracket 44 is fixedly provided on the outer wall of one side of the second rotating motor 45 by bolts, a nozzle 43 is installed through the fixing bracket 44, a sandblasting tube 27 is connected to the top of the nozzle 43, four groups of supporting feet 10 are fixedly provided in parallel on the outer wall of the top of the protective plate 11 by bolts, a sand storage box 9 is fixed on the top of the supporting feet 10, a feeding port 8 is connected to the top of the sand storage box 9, the top of the sandblasting tube 27 passes through the protective plate 11 and is connected to the bottom of the sand storage box 9, the bottom end of the sandblasting tube 27 is made of an anti-expansion telescopic hose, a sandblasting valve 28 is connected to one end of the sandblasting tube 27, a pressurizing port 12 is connected to one side of the sandblasting tube 27, a pressing contact 40 is installed at one end of the second rotating motor 45, and the pressing contact 40 is adapted to the polishing head 39;

When in use, the pressing contact 40 is connected to the sandblasting valve 28, and the rotating shaft of the second rotating motor 45 has a certain degree of elasticity. When the second rotating motor 45 descends for polishing, it drives the nozzle to descend 43. When the polishing head 39 contacts the workpiece, it is subjected to pressure to cause the rotating shaft to shrink, so that the pressing contact 40 contacts the polishing head 39. After contact, the sandblasting valve 28 is controlled to open to transport the sand material. The booster pump is connected through the pressure port 12 to accelerate the sand material and then spray it out, and spray it on the surface of the workpiece to remove the rust. When the polishing is completed, the second rotating motor 45 rises and the pressure is released to return the rotating shaft. The pressing contact 40 is disconnected from the polishing head 39, and the sandblasting valve 28 is controlled to close to prevent waste of sand material. The retractable hose is convenient for following the movement of the second rotating motor 45 to prevent the pipeline from being broken due to insufficient length.

When adding the finished sand material into the sand storage box 9, agglomerates may occur. If the agglomerates are not broken up, the agglomerates may damage the surface of the workpiece during rust removal. The handle 7 is held and rotated to drive the stirring blade 51 to rotate in the sand storage box 9 to stir the sand material and break it up.

In order to prevent splashing when adding sand, as shown in FIG. 2 , the feeding port 8 is trapezoidal in shape, with one side extending obliquely upward so that the opening gradually expands upward;

When in use, the trapezoidal feeding port 8 is used to prevent the sand from splashing out when adding sand to the sand storage box 9, and the opening gradually expands upwards to prevent the sand from splashing out when falling, and the inclined design can prevent the sand from remaining in the feeding port 8;

In order to seal the connection, as shown in FIG1 , a connection flange is installed at the end of the air inlet 6, another set of connection flanges is installed at the end of the connector 21, and a sealing gasket is installed on one side of the connection flange;

When in use, the connection with the pipeline is completed through the connecting flange, and the gap at the connection is filled with a sealing gasket to avoid the generation of gaps, ensure the sealing of the connection, and facilitate the transportation of gas;

In order to limit the running track of the piston 56, as shown in FIG2, a limit frame 30 is fixedly provided on the outer wall at the end of the piston cylinder 16 by bolts, and an opening is provided at the central position of the limit frame 30, and the opening is adapted to the second connecting rod 15;

When in use, the opening at the central position of the limiting frame 30 limits the second connecting rod 15, fixes its running track, and avoids the movement track of the second connecting rod 15 being offset, causing the piston 56 to be offset during operation and unable to be used normally.

Example 2

In order to prevent the device from shaking greatly during operation, referring to FIGS. 2 and 6 , a surface treatment device for a structural part is provided. Compared with the first embodiment, the present embodiment makes the following improvements: a sleeve 25 is fixedly provided on the outer wall of the bottom of the workbench 26 by bolts, and four groups of sleeves 25 are provided in parallel. A connecting rod 24 is slidably installed at one end of the sleeve 25, and a second spring 57 is installed between the connecting rod 24 and the sleeve 25. A supporting leg 23 is fixedly provided at the bottom of the connecting rod 24 by bolts, and a rubber anti-skid pad is installed at the bottom of the supporting leg 23;

When in use, the anti-skid pad made of rubber material increases the friction between the device and the ground when it is placed, preventing the device from sliding and displacement. When the device generates impact force during operation, the impact force can be absorbed by the contraction of the second spring 57, avoiding the device from shaking due to the impact force. When the shaking amplitude is large, the connection between the components will be disconnected, affecting the normal use of the device.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
