In addition, the lower end of the lead screw 33 is further provided with a lifting origin sensing block 50, and a lifting sensor bracket 51 is arranged at the lower part of the mounting beam 31, the upper and lower ends of the lifting sensor bracket 51 are respectively provided with a first proximity switch 52 and a second proximity switch 53, the first proximity switch 52 and the second proximity switch 53 cooperate with the lifting origin sensing block 50 to limit the lead screw 33 to lift within a certain range. The third servo motor 37 is the power source of the rotating movement, which drives the rotary support 39 to rotate through the speed reduction and torque increase of the third speed reducer 36.

[0061] Specifically, in use, first, the circular workpiece is loaded and transported by the carrier 17 to the jacking rotating assembly 3 in the sand blasting cabinet 1, more specifically, is placed on the support frame 311. Then, the lifting motor 32 is started, and the bearing plate 35 and the workpiece thereon are jacked to the required height through the transmission of the lead screw 33 and the connecting head 34. Next, the third servo motor 37 is started, and the third gear 38 is driven to rotate through the speed reduction and torque increase of the third speed reducer 36. The third gear 38 cooperates with the rack on the outer periphery of the slewing bearing 39 to make the slewing bearing 39 start to rotate. The rotation of the slewing bearing 39 is transmitted to the support frame 311 through the rotating column 310, and finally the stable rotation of the workpiece is realized. During the sand blasting process, the rotation speed and direction of the workpiece can be adjusted as needed to obtain the best sand blasting effect.

[0062] Further, the rotating column 310 is also provided with a dust cover 312 between the support frame 311 and the slewing bearing 39, which covers the main components to prevent the waste sand and dust generated during the sand blasting process from damaging the mechanical structure. In addition, for the same reason, the lead screw 33 is also provided with a dust sleeve 331.

[0063] Further, as a preferred embodiment of the present scheme but not limited, a first opening 174 matching the shape of the support frame 311 is formed on the carrying surface of the carrier 171, and the first opening 174 is communicated with a second opening 175 extending to the edge of the carrying surface of the carrier 171, and the second opening 175 is semi-closed so as to facilitate the lead screw 33 to pass through. When the carrier 171 loaded with the workpiece to be processed is moved to the vertical corresponding position of the first opening 174 and the support frame 311, the support frame 311 jacks the workpiece to be processed to separate from the carrier 171, and then moves the carrier 171 out of the sand blasting cabinet 1.

[0064] In the present embodiment, a first opening 174 matching the shape of the support frame 311 is specially formed on the carrying surface of the carrier 171. This first opening 174 not only matches the shape of the support frame 311, but also is communicated with the edge of the carrying surface of the carrier 171 through a second opening 175. Specifically, in the present embodiment, the support frame 311 is cross-shaped, and the first opening 175 is a corresponding cross-shaped with a slightly larger cross-sectional area than the support frame 311. It is foreseeable that in some other embodiments, the support frame 311 can also be H-shaped, circular, etc., and the present embodiment is only for illustration. The second opening 175 is designed as a semi-closed structure, which allows the lead screw 33 to pass through the edge of the vehicle body, so as to correspond the support frame 311 with the first opening 174.

[0065] Specifically, in use, first, the circular workpiece to be processed is placed on the carrying surface of the trolley 171, and it is ensured that the workpiece is located above the first opening 174. At this time, the trolley 171 is located outside or near the entrance of the sand blasting cabinet 1. The trolley 171 is moved into the sand blasting cabinet 1 together with the workpiece until the first opening 174 and the support frame 311 are in vertical correspondence. During this process, the accurate movement of the trolley 171 can be realized by the guide rails mentioned above or auxiliary equipment such as adding sensors. When the trolley 171 is positioned correctly, the lead screw 33 is started to drive, and the support frame 311 gradually rises through the first opening 174 and the second opening 175 until the top of the support frame 311 contacts the bottom of the workpiece and lifts it up. As the support frame 311 continues to rise, the workpiece is completely lifted off the carrying surface of the trolley 171, realizing the separation of the workpiece and the trolley 171. After the workpiece is stably supported, the trolley 171 can be separated from the lead screw 33 due to the arrangement of the second opening 175, and finally moved out of the sand blasting cabinet 1 to make room for subsequent sand blasting operations. At this time, the workpiece is completely supported by the support frame 311 and is ready to accept sand blasting treatment.

[0066] Further, the rotating support column 310 is also provided with a rotation origin stopper 312 rotating synchronously therewith, and the side end of the supporting plate 35 is provided with a third proximity switch 351 cooperating with the rotation origin stopper 312. When the rotation origin stopper 312 rotates to directly above the third proximity switch 351, it is the initial position of the support frame 311, and at this initial position, the support frame 311 is vertically corresponding to the first opening 174 and can pass through the first opening 174 to be lifted upward.

[0067] Further, the bottom of the sand blasting cabinet 1 is provided with a sand discharge valve 18 for collecting waste sand, the sand discharge valve 18 is connected with a corresponding sand storage tank through an external pipeline to realize the collection of waste sand, one side of the sand blasting cabinet 1 is connected with a dust extraction pipe 19, and a dust extraction cabinet 20 connected with the dust extraction pipe 19 through an external pipeline is arranged beside the sand blasting cabinet 1 for collecting waste dust generated inside the sand blasting cabinet 1 during operation.

[0068] In this embodiment, in order to effectively collect and process the waste sand generated during sand blasting, a sand discharge valve 18 is specially arranged at the bottom of the sand blasting cabinet 1. The sand discharge valve 18 guides the waste sand deposited at the bottom of the sand blasting cabinet into a special sand storage tank through an external pipeline, avoids the accumulation of waste sand in the sand blasting cabinet, reduces the frequency and difficulty of manual cleaning, and also realizes the centralized management and reuse of waste sand.

[0069] In order to solve the problem of waste dust generated in the sand blasting operation, the sand blasting cabinet 1 is provided with a dust extraction pipe 19 on one side. The dust extraction pipe 19 is connected with the dust collection cabinet 20 through an external pipeline to form a complete waste dust collection system. When the dust extraction pipe 19 sucks the waste dust, the waste dust will be directly sent into the dust collection cabinet 20. The inside of the dust collection cabinet is designed with efficient filtering and collecting devices to ensure that the waste dust is effectively captured and stored for subsequent centralized treatment and discharge.

[0071] The sand blasting device suitable for circular workpieces provided by the application comprises a sand blasting cabinet, and the sand blasting cabinet is used for accommodating the circular workpieces to be processed.

[0072] In the application, the sand blasting pipe movement assembly is composed of a mounting bracket, a lifting assembly, a horizontal movement assembly and a sand blasting pipe adjusting assembly. The lifting assembly drives the relative movement of the first gear and the first rack through the first servo motor to realize the accurate lifting of the sand blasting pipe in the vertical direction. The horizontal movement assembly realizes the movement of the sand blasting pipe in the horizontal direction through the relative movement of the second gear and the second rack driven by the second servo motor. The sand blasting pipe adjusting assembly is responsible for adjusting the spraying angle and distance of the sand blasting pipe relative to the workpiece to be processed to ensure the uniformity and effectiveness of the sand blasting treatment.

[0073] In the application, the jacking and rotating assembly is located below the sand blasting cabinet and realizes the jacking of the workpiece through the lead screw driven by the lifting motor. Meanwhile, the third servo motor drives the third gear to cooperate with the rack on the outer periphery of the slewing bearing through the third speed reducer to make the workpiece rotate in the horizontal plane. The combination of jacking and rotating enables the sand blasting pipe to comprehensively and uniformly treat the inner and outer surfaces of the workpiece.

[0074] In the application, the workpiece is loaded and transported into the sand blasting cabinet through the carrying device. The first opening on the carrying vehicle matches the shape of the support frame of the jacking and rotating assembly, so that the workpiece can be smoothly jacked up by the support frame and separated from the carrying vehicle. After the treatment is completed, the workpiece is unloaded in the same way.

[0075] In the application, the sand blasting cabinet is provided with a sand discharge valve at the bottom for collecting and treating waste sand. Meanwhile, the dust extraction pipe on one side of the sand blasting cabinet is connected with the dust collection cabinet to form a waste dust collection system to ensure the cleanliness of the sand blasting operation environment.

[0076] In summary, the sand blasting pipe movement assembly and the jacking and rotating assembly work together to realize comprehensive and uniform automatic sand blasting treatment of the inner and outer surfaces of the circular workpiece. At the same time, through the automatic design of the workpiece loading and unloading system and the effective treatment of waste sand and waste dust, the efficiency and environmental protection of the sand blasting operation are improved.
