DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides an embodiment:

[0025] A kind of positioning device for crack-free amorphous coating repair of roll surface, control panel 2, driving motor 9 and non-slip pad 18 used in the application are all products that can be directly purchased in market, its principle and connection mode are all prior art that is familiar to those skilled in the art, so here is not repeated, including operation table 1, control panel 2 is installed in the right side of operation table 1, sliding groove 3 is opened in the top surface of operation table 1, sliding positioning assembly is installed in the inside of sliding groove 3, supporting assembly is installed on the top surface of operation table 1;

[0026] The sliding positioning assembly includes a first sliding plate 4 and a second sliding plate 6, both of which are slidably mounted inside the slide groove 3. A first positioning roller 5 is mounted on the outer surface of the first sliding plate 4, and a second positioning roller 7 is mounted on the outer surface of the second sliding plate 6. A bidirectional lead screw body 8 is inserted and mounted inside both the first sliding plate 4 and the second sliding plate 6. A drive motor 9 is mounted on the back of the bidirectional lead screw body 8 and is mounted inside the operating table 1. A slider 10 is mounted on the right side of both the first sliding plate 4 and the second sliding plate 6, and the slider 10 is slidably mounted on the inner wall of the operating table 1. The distance between the first positioning roller 5 and the second positioning roller 7 is adjusted according to the size of the roll. At this time, the drive motor 9 is started, which drives the bidirectional lead screw body 8 to rotate. Then, the first sliding plate 4 and the second sliding plate 6 on the surface of the bidirectional lead screw body 8 will move closer or further away from each other. The first sliding plate 4 and the second sliding plate 6 are limited by the slider 10 when they move. After the first sliding plate 4 and the second sliding plate 6 are adjusted to the appropriate position, the first positioning roller 5 and the second positioning roller 7 support the roll. Thus, this setting can position different diameter sizes through the sliding positioning component, avoiding the previous method of directly aligning and positioning the two ends of the roll. This setting can quickly position and support the roll, and the operation is more convenient.

[0027] The support assembly includes a support cylinder 11, which is mounted on the upper surface of the operating table 1. A support frame 12, which has an inverted trapezoidal structure, is fixedly connected to the top surface of the support cylinder 11. The support cylinder 11 provides stable support for the support frame 12. Since the support frame 12 is installed below the first positioning roller 5 and the second sliding plate 6, it can play a safety role, preventing the rollers between the first positioning roller 5 and the second positioning roller 7 from falling directly. The overall installation is good, and because the support frame 12 is inverted trapezoidal, it can stably limit and support the rollers.

[0028] A sliding bracket 14 is slidably installed inside the adapter groove 13. A threaded post 15 is threaded inside the sliding bracket 14. A mounting bearing 16 is installed at the lower end of the threaded post 15. An abutment ring 17 is installed at the lower end of the mounting bearing 16. An anti-slip pad 18 is fixedly connected to the lower surface of the abutment ring 17. The lower surface of the anti-slip pad 18 is evenly provided with protrusions. During subsequent positioning, the sliding frame 14 is moved above the area of ​​the roll that does not need repair, and then the threaded column 15 is screwed inside the sliding frame 14. When the threaded column 15 rotates, it will drive the mounting bearing 16 and the abutment ring 17 downward. At this time, the threaded column 15 is installed inside the mounting bearing 16, so the rotation will not drive the abutment ring 17 to rotate. Thus, the anti-slip pad 18 at the lower end of the abutment ring 17 can abut against the upper surface of the roll, which can position the roll on the surface of the first positioning roll 5 and the second positioning roll 7. Therefore, this setting, through the setting of the support component, can protect the roll inside the first positioning roll 5 and the second positioning roll 7, and at the same time, it can position the upper surface of the roll inside the first positioning roll 5 and the second positioning roll 7.

[0029] Working principle: When using this device, the operator first connects it to an external power source to provide power. During use, the distance between the first positioning roller 5 and the second positioning roller 7 is adjusted according to the size of the roller. At this time, the drive motor 9 is started, which drives the bidirectional lead screw body 8 to rotate. Then, the first sliding plate 4 and the second sliding plate 6 on the surface of the bidirectional lead screw body 8 will move closer or further apart. The first sliding plate 4 and the second sliding plate 6 are limited by the slider 10 when moving. After the first sliding plate 4 and the second sliding plate 6 are adjusted to the appropriate position, the first positioning roller 5 and the second positioning roller 7 support the roller. Thus, this device can position different diameter sizes through the sliding positioning component.

[0030] The support cylinder 11 provides stable support for the bearing frame 12, which is installed below the first positioning roller 5 and the second sliding plate 6. Therefore, the bearing frame 12 can play a role in avoiding accidents and prevent the roller between the first positioning roller 5 and the second positioning roller 7 from falling directly. The overall installation is good. Then, during subsequent positioning, the sliding frame 14 is moved above the part of the roller that does not need repair. Then, the threaded column 15 is screwed inside the sliding frame 14. When the threaded column 15 rotates, it will drive the mounting bearing 16 and the abutment ring 17 downward. At this time, the threaded column 15 is installed inside the mounting bearing 16, so it will not drive the abutment ring 17 to rotate. Thus, the anti-slip pad 18 at the lower end of the abutment ring 17 can abut against the upper surface of the roller, which can position the roller on the surface of the first positioning roller 5 and the second positioning roller 7. The above is the working principle of this utility model.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
