DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0023] As shown in Figures 1-6 The present application provides an automatic polishing device for large metal barrels, which comprises a workbench 30, a barrel body 1, a barrel body fixing mechanism 2 and a barrel body rotating polishing mechanism 3 arranged on the workbench 30. The barrel body fixing mechanism 2 is used for positioning and clamping the barrel body and is composed of three groups of adaptive positioning claws 21 arranged at an angle of 120° on the circumference of the workbench. The barrel body rotating polishing mechanism 3 comprises a rotating wheel 31, a three-phase asynchronous motor 32, a bearing ring groove combination 33, a polishing linear module support 34, a polishing linear module 35, an arc-shaped polishing head 36, a telescopic cylinder 37 and a module sliding block 38. The bearing ring groove combination 33 is welded and fixed on the workbench 30. The polishing linear module 35 is connected to the polishing linear module support 34 by bolts. The polishing linear module support 35 is connected to the workbench 30 by bolts. The module sliding block 38 slides up and down under the driving of the polishing linear module 34. The telescopic cylinder 37 is connected to the module sliding block 38 by bolts. The arc-shaped polishing head 36 is fixed to the front end of the telescopic cylinder 37.

[0024] The barrel body fixing mechanism 2 positions and clamps the barrel body 1 through the three groups of adaptive positioning claws 21, ensuring that the barrel body is fixed firmly during polishing. The barrel body rotating polishing mechanism 3 rotates the barrel body 1 through the rotating wheel 31 and the three-phase asynchronous motor 32, so that the barrel body 1 can be uniformly stressed during polishing. The bearing ring groove combination 33 ensures the stability during rotation. The polishing linear module 35 and the polishing linear module support 34 are connected and fixed by bolts, realizing the up-and-down sliding of the polishing head. The cooperation of the telescopic cylinder 37 and the module sliding block 38 enables the polishing head to be adjusted flexibly. The arc-shaped polishing head 36 can effectively polish the weld inside the barrel body. Through the cooperation of these technical features, the automatic polishing of the weld inside the large metal barrel is realized, solving the problems of low efficiency and safety hazards in manual polishing.

[0025] Further, the application also proposes that the adaptive positioning clamp 21 is composed of a positioner 211, a positioner connecting piece 212, a structure support 213, a guide rail slider 214, a guide rail 215 and a linear module 216. The guide rail 215 is fixedly arranged on the upper surface of the workbench 30. The guide rail slider 214 is fixedly screwed on the guide rail 215. The linear module 216 is arranged in the middle of the two guide rails 215. The positioner connecting piece 212 is fixedly connected to the linear module 216. The positioner 211 is fixedly screwed on the positioner connecting piece 212. The structure support 213 is fixedly connected to the back of the positioner connecting piece 212. The structure support 213 is installed on the guide rail slider 214 through screws.

[0026] The adaptive positioning clamp 2 realizes adaptive positioning and clamping of the barrel body 1 through cooperation of the positioner 211, the positioner connecting piece 212, the structure support 213, the guide rail slider 214, the guide rail 215 and the linear module 216. The combination of the guide rail 215 and the guide rail slider 216 enables the positioner to move and adjust the position on the workbench. The linear module provides accurate positioning function. The positioner connecting piece 212 and the structure support 213 ensure the stability and reliability of the positioner. Through mutual cooperation of these technical features, adaptive positioning and clamping of the barrel body are realized, and the technical problem of how to realize adaptive positioning and clamping of the barrel body is solved.

[0027] The application provides a device capable of realizing adaptive positioning and clamping of a barrel body, and solves the problems of inaccurate positioning and unstable clamping in the prior art. Compared with the prior art, the device of the application has simple structure and is easy to implement. In addition, the positioning and clamping accuracy of the device can be improved without increasing excessive cost, and the device has high practical value.

[0028] Further, the application also proposes that the positioner 211 includes a positioner housing 2111, a positioner rear cover 2112, a spring 2113 and a positioning column 2114. The spring 2113 and the positioning column 2114 are installed inside the positioner housing 2111. The spring 2113 can enable the positioning column 2114 to autonomously adjust according to the external contour.

[0029] The spring 2113 provides elastic force, enabling the positioning column 2114 to flexibly adjust the position to adapt to different external contour shapes. This design enables the positioner to autonomously adjust according to the change of the external contour during use, improving the positioning accuracy and adaptability, and solving the problem that the positioner cannot autonomously adjust according to the external contour.

[0030] Further, the present application also proposes that the structural support 213 is in a triangular structure. The structural support 213 is in a triangular structure, which enhances the stability and support capacity of the structural support through the geometric stability of the triangle, effectively solving the problems of instability and insufficient support that may occur during polishing.

[0031] Further, the present application also proposes that the positioner connecting piece 212 is evenly distributed with 3 groups of screw-fixed positioners 211. The positioner connecting piece 212 can realize stable positioning of the barrel 1 by evenly distributing the positioners 211, ensuring the stability and precision of the polishing process. The uniform distribution of multiple positioners 211 can effectively disperse the force, avoiding the wear or failure of a single positioner due to excessive force, thereby improving the service life and safety of the device. Through this technical means, the technical problem of how to evenly distribute multiple positioners on the positioner connecting piece can be solved, ensuring stable positioning of the barrel during polishing and improving the efficiency and quality of polishing.

[0032] Further, the present application also proposes that the bearing ring groove combination 33 is composed of a ring groove 331, a cylindrical stick bearing connecting shaft 332 and a cylindrical stick bearing 333. The ring groove 331 is evenly distributed with 10 circular holes, 10 cylindrical stick bearing connecting shafts 332 are installed on the circular holes, and cylindrical stick bearings 333 are installed on the cylindrical stick bearing connecting shafts. Through this design, the bearing ring groove combination can provide stability and efficient operation during polishing. The ring groove provides a stable foundation, while the evenly distributed circular holes and bearing connecting shafts ensure uniform distribution of force during polishing, reducing eccentricity and vibration. The use of cylindrical stick bearings further improves the durability and operation efficiency of the device, ensuring smooth and efficient operation of large metal barrels during polishing.

[0033] Further, the present application also proposes that the polishing linear module 35 is provided with a camera 39. The feature of setting a camera on the polishing linear module can monitor the polishing process in real time through the camera, ensuring accurate polishing of the weld, improving the degree of automation and efficiency of polishing, reducing manual intervention, and reducing safety hazards. The real-time monitoring function of the camera cooperates with the polishing function of the linear module, which can effectively solve the problems of automation and efficiency of polishing the internal weld of large metal barrels.

[0034] Working principle: in the polishing process, the barrel fixed mechanism 2 is positioned and clamped by three groups of adaptive positioning clamps 21 to the barrel 1, ensuring that the barrel 1 is fixed firmly during polishing. The barrel rotating polishing mechanism 3 drives the barrel to rotate through the rotating wheel 31 and the three-phase asynchronous motor 32, so that the barrel 1 can be uniformly stressed during polishing. The bearing ring groove combination 33 ensures stability during rotation. The polishing linear module 35 and the polishing linear module support 34 are fixed by bolt connection, realizing the up and down sliding of the polishing head. The cooperation of the telescopic cylinder and the module slider makes the polishing head flexible, and the arc-shaped polishing head 36 can effectively polish the weld inside the barrel.
