Description

Technical Field

[0001] The utility model relates to the technical field of rust removal equipment, in particular to a steel cylinder rust removal machine. Background Art

[0002] A steel cylinder is a steel cylinder for storing high-pressure oxygen, coal gas, liquefied petroleum gas, etc., and the steel cylinder is painted on the outside during production. As the cylinder is bumped during transportation, the paint on the outer surface of the cylinder will fall off and oxidize and rust. If not handled in time, the service life of the cylinder will be reduced. The patent number is CN218194422U, and the name is an automatic rust removal machine for steel cylinders. The cylinder is rotated by a roller and fixed by rotation. However, one end of the cylinder is conical, so that when the cylinder is fixed, the contact surface between the fixing device and the conical surface is relatively small, and the fixing force is insufficient, so that the cylinder is easily misaligned while rotating at high speed, affecting the coaxial fixation of the cylinder, which is prone to rust removal errors, and serious damage to the cylinder, causing the cylinder to be scrapped.

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Steel cylinder derusting machine, such as Figure 1 As shown, it comprises two side frames 1 placed vertically and symmetrically, and a steel cylinder grinding device 2 which can be horizontally moved on the rotating screw 4 and a steel cylinder placing table 3 fixed directly below the steel cylinder grinding device 2 are provided at the upper end of the side frame 1 through a horizontally placed rotating screw 4;

[0020] A steel cylinder fixing device 7 is provided between the steel cylinder placing table 3 and the steel cylinder polishing device 3;

[0021] like Figure 2 As shown, the upper end surface of the cylinder placement platform 3 is a concave arc surface, and a horizontally placed gear rod 5 is provided at the lowest point of the upper end surface of the cylinder placement platform 3, and the gear rod 5 is rotated by a rotating motor 6 fixed in the side frame 1;

[0022] like Figure 3 As shown, the cylinder fixing device 7 includes a rotating fixed plate 71 whose right end is slidably connected to the side frame 1 through a rotating ring 8, and a rotating movable ring 72 which is slidably connected to the connecting plate 10 through the rotating ring 8, so that the rotating fixed plate 71 and the rotating movable ring 72 can rotate relative to the side frame 1; at the same time, the connecting plate 10 is fixedly connected to the cylinder fixed in the side frame 1, so that the rotating movable ring 72 can move linearly;

[0023] like Figure 4 As shown, the cylinder grinding device 2 is threadedly connected to the rotating screw 4 through the connecting plate 11, and the chip guide device 9 is fixedly connected to the connecting plate 11, so that the chip guide device 9 moves with the movement of the cylinder grinding device 2, and the motor shaft of the grinding disc rotating motor 22 is fixedly connected to the grinding disc 21.

[0024] When in use, the steel cylinder is placed on the steel cylinder placement table 3 from the rear of the device. When placing the steel cylinder, the conical head of the steel cylinder is directed toward the rotating movable ring 72. Then, the cylinder in the side frame 1 is started to push the connecting plate 10, so that the rotating movable ring 72 is sleeved on the conical head of the steel cylinder until the other end of the steel cylinder abuts against the rotating fixed plate 71, and the rotating movable ring 72 can no longer move, thereby achieving the fixing of the steel cylinder.

[0025] Since the upper end surface of the gear rod 5 protrudes from the lowest point of the upper end surface of the steel cylinder placement table 3, the gear rod 5 abuts against the steel cylinder. At this time, the gear rod 5 will be driven to rotate by starting the rotating motor 6, and then the steel cylinder is rotated due to the friction between the gear rod 5 and the steel cylinder. Since the rotating movable ring 72 and the rotating fixed disk 71 at the position where the steel cylinder fixing device 7 is fixedly abutted against the steel cylinder can rotate relative to the side frame 1, that is, when the steel cylinder rotates, the rotating movable ring 72 and the rotating fixed disk 71 can be driven to rotate together, so that the steel cylinder rotates when it is fixed;

[0026] At this time, the rotating screw 4 is started to make the cylinder grinding device 2 move horizontally on the rotating screw 4. During the movement of the cylinder grinding device 2, the grinding disc rotating motor 22 is started to make the grinding disc 21 rotate. The grinding disc 21 rotates while abutting against the cylinder, so that the rust on the surface of the cylinder can be scraped off. Since the chip guide device 9 is fixedly connected to the connecting plate 11, and the cylinder grinding device 2 is also screwed to the rotating screw 4 through the connecting plate 11, the cylinder grinding device 2 is in the process of grinding the cylinder. The rust chips polished out directly fly into the chip guide device 9 and are exported to the outside of the cylinder placement table 3 to prevent the rust chips from falling onto the cylinder placement table 3, affecting the change of the cylinder placement concentric axis, and further affecting the rust removal accuracy.

[0027] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
