[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This application enables rapid installation and removal of the scraper, significantly reducing the time required for scraper replacement while ensuring the positioning accuracy of the scraper. Specifically, the sliding adjustment block and the cooperation between the limiting block and the limiting groove ensure stable sliding and positioning of the adjusting seat on the tool holder, adapting to the clamping requirements of scrapers of different widths and achieving precise control of the scraper's installation position. The limiting structure securely fixes the adjusting seat to the tool holder, improving the reliability of the adjusting seat's fixation on the tool holder, while the combination of the clamping groove and the locking component effectively ensures the stability of the scraper during clamping, preventing loosening or displacement during processing, thereby improving the scraper's installation efficiency and positioning accuracy.

[0018] 2. This application effectively improves the stability of the adjusting seat during sliding by using the cooperation of the guide bar and guide groove, preventing the adjusting seat from shifting or jamming. Combined with the limiting structure, this design makes the position adjustment of the adjusting seat more precise.

[0019] 3. This application incorporates a slidable top block within the guide groove, driven by a first elastic element to slide towards the guide bar. When the limiting bolt is loosened, the first elastic element and the top block apply a certain elastic support force to the adjusting seat, increasing the structural stability of the adjusting seat on the blade holder and facilitating the installation and positioning of the blade. Furthermore, the rollers on the end face of the top block are rolled into the guide bar, significantly reducing the frictional resistance of the adjusting seat during sliding, resulting in smoother position adjustment and extending the service life of the guide bar and guide groove.

[0020] 4. This application utilizes an adjusting screw.

[0027] The following will be combined with the appendix Figure 1 - Appendix Figure 5 The technical solutions in the embodiments of the present invention are clearly and completely described herein. The described embodiments are only possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of the present invention without creative effort, and these embodiments are also within the protection scope of the present invention.

[0028] The inventors of this application discovered that during the process of scraping the teeth of heat sinks, different types of heat sinks have different sizes, requiring scrapers of different widths. However, due to the structural limitations of the scrapers, each scraper has a corresponding clamp to achieve precise positioning and fixation. Changing to scrapers of different widths requires frequent disassembly and reassembly of the clamps, which is cumbersome and time-consuming, severely impacting production efficiency. Therefore, this application discloses an adjustable single scraper clamping device, mainly employing the following solution: Example 1

[0029] Embodiment 1 of this application discloses an adjustable single-blade clamping device. (Refer to...) Figure 1 The system includes a tool holder 1 and an adjusting seat 2. The tool holder 1 is fixed to the machine tool with bolts. An adjusting groove 11 is provided on the tool holder 1 along its length. Two adjusting blocks 12 are slidably arranged in the adjusting groove 11 along the length of the adjusting seat 2. There are two adjusting seats 2, which correspond one-to-one with the adjusting blocks 12. The adjusting seats 2 are set on the corresponding adjusting blocks 12. A limit structure is provided on the adjusting seats 2 to fix the adjusting seats 2 on the tool holder 1. A clamping groove 21 for clamping the scraper is provided at the end of the two adjusting seats 2 that are close to each other. A locking component is provided on both adjusting seats 2 to fix the scraper in the clamping groove 21.

[0030] Reference Figure 1 A mounting bracket 3 is fixedly mounted on the tool holder 1. An adjusting screw 31 is threadedly connected to the mounting bracket 3. The mounting bracket 3 has multiple threaded holes 32 that are adapted to the adjusting screw 31, and the threaded holes 32 are evenly distributed along the sliding direction of the adjusting block 12. When the scraper is installed, the adjusting screw 31 is screwed into the corresponding threaded hole 32 on the mounting bracket 3, and the adjusting screw 31 is positioned between the two adjusting seats 2. Then, by rotating the adjusting screw 31, the adjusting screw 31 abuts against the tail end of the scraper, thereby achieving precise positioning of the scraper in the clamping groove and ensuring the structural stability of the scraper after clamping. In addition, rotating the adjusting screw 31 can also push the scraper to slide in the clamping groove, achieving precise adjustment of the scraper's front and rear positions, thereby adapting to scrapers of different lengths or processing requirements, improving the flexibility and applicability of the clamping device.

[0031] Reference Figure 1 and Figure 2 The tool holder 1 can be made of aluminum alloy or stainless steel, which has high strength and wear resistance. Limiting blocks 121 are fixedly provided on both sides of the adjusting block 12, and limiting grooves 111 for sliding of the limiting blocks 121 are opened on both sides of the adjusting groove 11. The limiting blocks 121 on both sides of the adjusting block 12 are integrally formed with the adjusting block 12, and the shape of the limiting grooves 111 is adapted to the limiting blocks 121 to ensure the stable sliding of the adjusting block 12 in the adjusting groove 11.

[0032] Reference Figure 1 and Figure 2 Specifically, the limiting structure includes multiple limiting bolts 22. The adjusting seat 2 has multiple through holes, and each limiting bolt 22 corresponds to one of these through holes, passing through the corresponding through hole. Each limiting bolt 22 is threaded into its corresponding adjusting block 12. By tightening the limiting bolts 22, the adjusting seat 2 is pressed against the end face of the tool holder 1, thus limiting the adjustment seat 2 and improving the reliability of fixing the adjusting seat 2 to the tool holder 1. The limiting bolts 22 can be made of high-strength alloy steel with a hardened surface to improve durability.

[0033] Reference Figure 1 and Figure 3 Furthermore, both the adjusting seat 2 and the tool holder 1 have anti-slip textures 4 on their adjacent end faces. The anti-slip textures 4 can be serrated or wavy to increase friction and prevent the adjusting seat 2 from becoming loose. In addition, the depth of the anti-slip textures 4 can be adjusted according to actual needs, for example, set between 0.5mm and 2mm, to achieve the best anti-slip effect.

[0034] Reference Figure 2 and Figure 3A guide bar 13 is provided on the end face of the tool holder 1 near the adjusting seat 2. Two guide bars 13 are provided, located on either side of the adjusting groove 11. The guide bars 13 are integrally formed with the tool holder 1. The length direction of the guide bars 13 is parallel to the sliding direction of the adjusting block 12. Two guide grooves 23 are provided on the end of the adjusting seat 2 near the tool holder 1. The guide grooves 23 correspond one-to-one with the guide bars 13 and are adapted to fit the guide bars 13. The guide bars 13 are positioned within the guide grooves 23. The surface of the guide bars 13 is polished to reduce frictional resistance. The cooperation between the guide bars 13 and the guide grooves 23 effectively improves the stability of the adjusting seat 2 during sliding, preventing the adjusting seat 2 from shifting or jamming. Combined with the limiting structure, this design makes the position adjustment of the adjusting seat 2 more precise.

[0035] Reference Figure 3 A receiving groove 24 is formed on the side wall of the guide groove 23 away from the blade holder 1. A top block 25 is slidably disposed in the receiving groove 24 along the direction close to or away from the guide bar 13. A first elastic element is provided in the receiving groove 24 to drive the top block 25 to slide towards the guide bar 13. Specifically, the first elastic element includes an elastic steel sheet 26, which is U-shaped and installed in the receiving groove 24. The elastic steel sheet 26 abuts against the top block 25 and the side wall of the receiving groove 24 away from the guide bar 13, so that the top block 25 always has a tendency to slide towards the guide bar 13, thereby applying a certain elastic support force to the adjusting seat 2, increasing the structural stability of the adjusting seat 2 on the blade holder 1, and facilitating the installation and positioning of the blade. In addition, the first elastic element can also be a spring or elastic rubber.

[0036] Reference Figure 3 Multiple rollers 251 are rotatably mounted on the end face of the top block 25 near the guide bar 13, and the rollers 251 are in rolling connection with the guide bar 13. The rollers 251 can be made of stainless steel or ceramic material, which has high hardness and wear resistance, and can significantly reduce the frictional resistance of the adjusting seat 2 during the sliding process, making the position adjustment of the adjusting seat 2 smoother, and at the same time extending the service life of the guide bar 13 and the guide groove 23.

[0037] Reference Figure 4Specifically, the locking assembly includes locking blocks 5 and locking components. Multiple locking blocks 5 are provided, and each locking block 5 can be made of high-strength alloy steel with a hardened surface treatment to improve durability. Each locking block 5 has a pressing part 51 for abutting against the shovel blade, and the pressing part 51 is integrally formed with the locking block 5. Multiple locking bolts 52 are provided, each corresponding to one of the locking blocks 5. Each locking block 5 has a mounting hole 53, and the locking bolt 52 passes through the corresponding mounting hole 53 of the locking block 5, and the locking bolt 52 is threadedly engaged with the corresponding adjusting seat 2. The locking bolts 52 can be made of high-strength alloy steel with a galvanized surface treatment to improve corrosion resistance. The locking bolt 52 fixes the corresponding locking block 5 on the adjusting seat 2. The pressing part 51 on the locking block 5 presses against the surface of the shovel, thereby firmly fixing the shovel in the clamping groove, effectively preventing the shovel from loosening or shifting during processing, and improving the reliability of shovel clamping.

[0038] Reference Figure 4 Each locking block 5 is equipped with a positioning sleeve 54. The positioning sleeve 54 is cylindrical and integrally formed with the locking block 5. The mounting hole 53 communicates with the positioning sleeve 54. The locking bolt 52 passes through the positioning sleeve 54 of the corresponding locking block 5, and the locking bolt 52 is adapted to the positioning sleeve 54. The adjusting seat 2 has multiple positioning grooves 27 adapted to the positioning sleeves 54. The positioning grooves 27 correspond one-to-one with the locking blocks 5, and the positioning sleeves 54 on each locking block 5 pass through the corresponding positioning grooves 27. The positioning sleeves 54 serve as guides for the movement of the locking blocks 5, allowing the locking blocks 5 to slide towards or away from the adjusting seat 2 while rotating around the positioning sleeves 54 as the rotation axis. At the same time, it ensures that the locking blocks 5 will not shift during the locking and fixing of the blade, thus improving the reliability of the locking assembly. In addition, the matching design of the positioning groove 27 and the positioning sleeve 54 simplifies the assembly process of the locking components and improves assembly efficiency.

[0039] Reference Figure 4 The positioning groove 27 is provided with a second elastic element for driving the positioning sleeve 54 to slide away from the positioning groove 27. The second elastic element is a compression spring 28, which is sleeved on the locking bolt 52. One end of the compression spring 28 abuts against the lower side wall of the positioning groove 27, and the other end abuts against the positioning sleeve 54. The second elastic element can provide a certain elastic support force for the positioning sleeve 54. When the locking bolt 52 is loosened, the positioning sleeve 54 can move away from the adjusting seat 2 under the elastic force of the second elastic element, providing sufficient space for the installation of the shovel and improving the convenience of shovel installation.

[0040] Reference Figure 4The adjusting seat 2 has multiple limiting slots 29, each corresponding to a positioning slot 27. The limiting slots 29 are also connected to the mounting slot 21 and the corresponding positioning slot 27. The limiting slots 29 are adapted to the locking block 5 and are used to engage the corresponding locking block 5. The limiting slots 29 ensure precise engagement of the locking block 5, effectively preventing it from shifting during the fixing process. This enhances the reliability of the locking assembly and prevents the locking block 5 from deflecting or loosening due to external forces, thus ensuring the stability of the scraper during processing. Furthermore, the connection between the limiting slots 29, positioning slots 27, and mounting slots 21 guides the installation of the locking block 5, simplifying the operation and improving assembly efficiency.

[0041] The implementation principle of the adjustable single shovel clamping device in Embodiment 1 of this application is as follows: the sliding adjustment block 12 and the cooperation between the limiting block 121 and the limiting groove 111 ensure the stable sliding and positioning of the adjusting seat 2 on the shovel holder 1, adapting to the clamping requirements of shovels of different widths, and realizing precise control of the shovel installation position. The setting of the limiting structure can firmly fix the adjusting seat 2 on the shovel holder 1, improving the reliability of fixing the adjusting seat 2 on the shovel holder 1, while the combination of the clamping groove 21 and the locking component effectively ensures the stability of the shovel during the clamping process, avoiding loosening or displacement during processing, thereby improving the installation efficiency and positioning accuracy of the shovel. Example 2

[0042] Reference Figure 5 The difference from Embodiment 1 is that: a groove 33 is provided on the mounting bracket 3 along the sliding direction of the adjusting block 12, and a slider 34 is slidably disposed in the groove 33. An adjusting screw 31 passes through the slider 34 and is threadedly engaged with the slider 34. A top rod 35 is rotatably sleeved on the adjusting screw 31. The top rod 35 is located between the two adjusting seats 2. When the adjusting seats 2 slide, the slider 34 slides together with the adjusting seats 2. When the scraper is installed, by rotating the adjusting screw 31, the top rod 35 abuts against the tail end of the scraper, thereby achieving precise positioning of the scraper in the clamping groove and improving the convenience of use.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
