Description

Technical Field

[0001] The utility model relates to the technical field of tank body processing, in particular to a polishing device for a gas storage tank. Background Art

[0002] After the gas tank is welded and formed, some weld scars will appear, and the tank body is also a rough blank, so a polishing device is needed to grind and polish the tank body. For example, Chinese patent "CN220740669U" discloses "a tank body polishing device". This device rotates a bidirectional screw, so that the connecting block drives the support frame to move toward each other along the adjustment groove, so that the suction cup is adsorbed on the tank body to be polished. When the No. 1 motor is turned on, the rotating shaft drives the suction cup to rotate, and the tank body also rotates accordingly. When the telescopic cylinder is turned on, the driver drives the polishing wheel to move toward the tank body and contact the tank body, achieving a rapid fixation effect on tank bodies of different sizes. However, when the above device installs the tank body through the suction cup, it cannot ensure that the axis of the tank body is in line with the axis of the motor. As a result, when the motor drives the tank body to move, the tank body will swing at a certain angle, thereby reducing the quality of the tank body polishing. Utility Model Content

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 and Figure 2 As shown, the embodiment of the present utility model provides a gas tank polishing device for processing a tank body 1, comprising:

[0025] The base 2 is provided with a polishing machine 3 for sliding;

[0026] The column 8 is fixed to the base 2 and is rotatably provided with a bearing rod 5, and the tank body 1 is sleeved on the bearing rod 5;

[0027] The fixing unit includes several fixing plates 502 arranged along the circumference of the supporting rod 5, a slide 505 slidably provided on the supporting rod 5, and an adjusting member rotatably provided on the supporting rod 5. The fixing plate 502 is rotatably provided with two adjusting rods 501, and the two adjusting rods 501 are rotatably provided on the supporting rod 5 and the slide 505 respectively. The adjusting member is connected to the slide 505 and is used to make the slide 505 move on the supporting rod 5 so that each fixing plate 502 moves away from or approaches each other.

[0028] In the embodiment of the present invention, the polishing machine 3 is a traditional polishing and grinding robot arm, which can be controlled in multiple directions by an external controller. In the initial state, each fixed plate 502 is in a contracted state, that is, each fixed plate 502 is close to each other, so that the tank body 1 is conveniently placed on the support rod 5 through its mouth, and the tank body 1 is supported by the support rod 5. Under the influence of the gravity of the tank body 1, the inner wall of the tank body 1 first abuts against the fixed plate 502 located at the top of the support rod 5, and the remaining fixed plates 502 are all at a certain distance from the inner wall of the tank body 1. The position of the slide 505 is adjusted by the adjustment member, so that the slide 505 moves on the support rod 5. Under the movement of the slide 505, the ends of the two adjustment rods 501 are spaced apart. The distance between them is getting closer and closer, and the angle of the two adjusting rods 501 becomes smaller, so that the two adjusting rods 501 lift the fixed plates 502 connected to them. Since one of the adjusting rods 501 of each fixed plate 502 is on the slide 505, the movement of the slide 505 can drive each fixed plate 502 to move synchronously, so that when each fixed plate 502 is in contact with the inner wall of the tank body 1, the axis of the tank body 1 is made collinear with the axis of the supporting rod 5. When the supporting rod 5 rotates on the column 8, it drives the tank body 1 to rotate together, and always ensures that the axis of the tank body 1 is collinear with the axis of the supporting rod 5, effectively avoiding the shaking problem of the tank body 1 caused by poor centering, and improving the stability and quality of the polishing process.

[0029] Secondly, as the fixing plates 502 move away from or closer to each other, the size of the arcs formed by the fixing plates 502 also changes accordingly. Therefore, in the process of adjusting the fixing plates 502, the fixing plates 502 can be fitted to the inner side of the tank bodies 1 with different inner diameters, making it convenient to polish the tank bodies 1 with different inner diameters and improving applicability.

[0030] Based on the above scheme, if Figure 4 As shown, the adjusting member includes an adjusting screw 6 rotatably arranged on the supporting rod 5 and a driving block 504 slidably arranged on the supporting rod 5 . The driving block 504 is threadedly connected to the adjusting screw 6 and fixedly connected to the slide cylinder 505 .

[0031] Specifically, when the position of the slide 505 is adjusted and limited by the action of the adjusting member, the driving block 504 has an internal thread, and the driving block 504 is threadedly connected to the adjusting screw 6 through the internal thread. When the adjusting screw 6 is rotated forward and reversed, the adjusting screw 6 drives the driving block 504 to slide left and right in the supporting rod 5, so that the driving block 504 drives the slide 505 to move synchronously. After the adjustment is completed, the rotation of the adjusting screw 6 can be stopped directly, so that the driving block 504 can be self-locked under the action of the thread, thereby fixing the position of each fixed plate 502, and under the action of the thread, the distance between the fixed plates 502 can be finely adjusted, so as to better adapt to tanks 1 with different diameters.

[0032] Moreover, an adjustment block 601 is provided at one end of the supporting rod 5, and the end of the adjusting screw 6 is fixedly connected to the adjustment block 601; the adjustment block 601 can be a nut or other polygonal block structure, which is convenient for adjusting the adjusting screw 6 using tools such as wrenches, which is more labor-saving.

[0033] Based on the above scheme, if Figure 3 As shown, it also includes two pulleys 7 rotatably arranged on the column 8, the two pulleys 7 are connected by a belt 701, the column 8 is provided with a driver 702, the driver 702 is connected to one of the pulleys 7, and the other pulley 7 is fixedly connected to the supporting rod 5.

[0034] In order to further reduce the manpower input, the two pulleys 7 are connected by a belt 701, which can effectively transmit the power of the driver 702 to the supporting rod 5. The driver 702 adopts any one of an electric motor and a motor. When the tank body 1 is polished, by starting the driver 702, the output shaft of the driver 702 drives the connected pulley 7 to rotate, thereby driving the supporting rod 5 to rotate under the action of the belt 701 and the pulley 7, so that the supporting rod 5 drives the fixed and installed tank body 1 to rotate, thereby realizing a large range of polishing operations.

[0035] Specifically, such as Figure 4 As shown, the fixing plate 502 has an arc-shaped structure. This arc-shaped structure allows the fixing plate 502 to better conform to the outer surface of the can body 1, maximizing the contact area between the fixing plate 502 and the can body 1. This provides a more uniform clamping force, effectively reducing shaking and deviation of the can body during the polishing process, improving the stability of the polishing process, and ensuring the polishing quality. Furthermore, the arc-shaped surface of the fixing plate 502 is provided with an anti-slip layer 503. This anti-slip layer 503 significantly increases the friction between the fixing plate 502 and the surface of the can body 1, ensuring that the can body 1 does not slip or deflect during the polishing process.

[0036] Specifically, such as Figure 1 As shown, the column 8 is fixed with an extension tube 4, the inner side of the extension tube 4 is provided with a bearing, and the load-bearing rod 5 is connected to the inner circle of the bearing; the contact area between the column 8 and the load-bearing rod 5 is increased through the action of the extension tube 4, thereby ensuring the stability of the load-bearing rod 5 during use.

[0037] At the same time, a reinforcing plate 401 is provided at the bottom of the extension tube 4, and the reinforcing plate 401 is connected to the column 8; the reinforcing plate 401 can significantly improve the connection strength between the extension tube 4 and the column 8, increase the structural rigidity, and ensure the stability and reliability of the entire device.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
