Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a polishing device for parts processing. Background Technology

[0002] Belt sanders are common tools for polishing parts, but it's important to choose the right sanding belt and polishing belt. Belt sanders grind the surface of workpieces through friction between the sanding wheel and the workpiece. They are suitable for workpieces with complex shapes and irregular surfaces, and can achieve good polishing results.

[0003] However, most existing belt sanders use only one grinding belt, and very few use more than two. This limits the performance of belt sanders in polishing parts; they can only perform simple coarse grinding or polishing at one grit. For finer polishing, either the grinding belt or the polishing equipment must be replaced. Therefore, we propose a parts processing and polishing device. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 2 This utility model provides a technical solution: a parts processing and polishing device, including a strip-shaped base 1, with multiple strip-shaped support seats 14 at the bottom of the strip-shaped base 1. The strip-shaped base 1 is positioned in the middle of the strip-shaped support seats 14, with both ends of the strip-shaped support seats 14 located outside the strip-shaped base 1, thus making the strip-shaped base 1 more stable. A frame is provided on the top of the strip-shaped base 1, such as... Figure 1 and Figure 2 As shown, the frame includes a vertical frame 3 set on top of the strip base 1. The top of the vertical frame 3 is connected by a connecting beam 6, and the two ends of the connecting beam 6 are respectively connected to the strip base 1 through a support frame 16.

[0024] This application also includes multiple polishing mechanisms spaced apart on the sides of the frame, each corresponding to a vertical frame 3. Each polishing mechanism includes a support wheel 10 and a drive wheel 15, with the drive wheel 15 connected to the support wheel 10 via a polishing belt 19. Figure 1 and Figure 2 As shown, each polishing mechanism is equipped with a polishing belt 19, and multiple polishing belts 19 are arranged side by side. From one end to the other, the polishing mesh number of the polishing belt 19 gradually increases, so that different mesh numbers can be polished. In practical applications, the polishing belt 19 on one of the polishing mechanisms is set as an abrasive belt, so that the parts can be polished faster.

[0025] like Figure 1 As shown, one end of the support wheel 10 is rotatably mounted inside the second support 11. The second support 11 is mounted on the frame via an adjustment mechanism. Specifically, the second support 11 is mounted on the vertical frame 3. The adjustment mechanism is used to adjust the tension of the support wheel 10. Figure 1 and Figure 4 As shown, the specific structure of the adjustment mechanism includes a support guide rail 7, a slider 5 connected to the second support 11 is slidably mounted on the support guide rail 7, an adjustment seat 4 is provided on the side of the second support 11 away from the support wheel 10, an adjustment screw 9 parallel to the support guide rail 7 is installed on the internal thread of the adjustment seat 4, the two ends of the adjustment screw 9 are rotatably mounted in the first support 8, the first support 8 and the support guide rail 7 can be detachably mounted on the frame, the first support 8 and the support guide rail 7 are set on the side of the vertical frame 3, specifically, the first support 8 and the support guide rail 7 are respectively fastened to the vertical frame 3 by bolts, the second support 11 and the slider 5 are also fastened by bolts;

[0026] To facilitate the rotation of the adjusting screw 9, a hexagonal head 18 is provided at the top of the adjusting screw 9. The specific adjustment process is as follows: when the polishing belt 19 needs to be replaced, simply use a wrench to turn the hexagonal head 18 to rotate the adjusting screw 9, causing the adjusting screw 9 to lower the support wheel 10. At this point, the polishing belt 19 will lose its support and can be removed. Then, a new polishing belt 19 can be installed. Then, turning the hexagonal head 18 in the opposite direction will raise the support wheel 10 and tighten the polishing belt 19. The adjusting screw 9 is equipped with at least one nut to secure it (e.g., ...). Figure 2 (As indicated by the middle arrow A), once the support wheel 10 is in the correct position, the adjusting screw 9 can be fixed with the nut.

[0027] It should be noted that the adjusting screw 9 and the adjusting seat 4 can achieve self-locking, but in order to ensure that the adjusting screw 9 is stable enough, it is tightened again with a nut.

[0028] The specific mounting structure of drive wheel 15 will be described below, such as... Figure 2 and Figure 4 As shown, one end of the drive wheel 15 is rotatably connected to the housing 12, and its end extends into the housing 12. A second mounting shaft 26, perpendicular to the drive wheel 15, is provided inside the housing 12. The second mounting shaft 26 is rotatably connected to the housing 12, and its end extends outside the housing 12. Both the second mounting shaft 26 inside the housing 12 and the end of the drive wheel 15 are provided with meshing bevel gears 27. The housing 12 is mounted on the strip-shaped base 1. The housing 12 and the strip-shaped base 1 are detachable, such as... Figure 4 As shown, specifically, two L-shaped supports 20 are symmetrically provided at one end of the housing 12 near the strip-shaped base 1. The L-shaped supports 20 are detachably connected to the strip-shaped base 1, that is, the L-shaped supports 20 and the strip-shaped base 1 are fastened by bolts.

[0029] The end of the second mounting shaft 26 away from the housing 12 is respectively connected to the first mounting shaft 22 (e.g., Figure 3 (As shown) Coaxially connected, the first mounting shaft 22 is rotatably mounted inside the strip-shaped base 1, and the end of the first mounting shaft 22 away from the housing 12 is driven to rotate by the same driving device. In order to facilitate the disassembly of the housing 12, a spline sleeve 21 is provided at the end of the second mounting shaft 26 away from the housing 12, and a spline head 17 matching the spline sleeve 21 is provided at the end of the first mounting shaft 22. When the L-shaped support 20 is installed on the strip-shaped base 1, the spline head 17 is placed inside the spline sleeve 21. When the bolts on the L-shaped support 20 are removed, the housing 12 is separated from the strip-shaped base 1, and the spline head 17 is also pulled out from the spline sleeve 21. This not only facilitates the installation of the housing 12, but also facilitates the disassembly of the housing 12.

[0030] The specific structure of the aforementioned drive device is as follows: Figure 3 As shown, it includes pulleys 23 mounted on the end of the first mounting shaft 22. The pulleys 23 are connected by a belt. One end of the first mounting shaft 22 is connected to a drive motor 25. The drive motor 25 is fixed on the strip-shaped base 1 or mounted on the strip-shaped support base 14. When the drive motor 25 rotates, it can drive each of the first mounting shafts 22 to rotate. The first mounting shaft 22 can drive the drive wheel 15 to rotate through the cooperation of the spline head 17 and the spline sleeve 21, causing multiple polishing belts 19 to rotate simultaneously.

[0031] Furthermore, the side of the housing 12 away from the strip-shaped base 1 is an opening, and a sealing cover 13 is detachably installed on the edge of the opening. Lubricating oil is provided inside the housing 12, and an oil filling hole is provided on the housing 12. The oil filling hole is sealed with bolts, and the edge of the sealing cover 13 is fastened to the edge of the housing 12 with bolts. After opening the sealing cover, it is convenient to inspect the gear.

[0032] Furthermore, such as Figure 3 As shown, the end of the strip-shaped base 1 away from the housing 12 is provided with a mounting groove 24, and the pulley 23 is located in the mounting groove 24. In reality, the mounting groove 24 can be sealed by a sealing plate, which can reduce noise.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, an L-shaped bracket 2 is provided in the middle of the polishing belt 19. The other end of the L-shaped bracket 2 is detachably installed on the vertical frame 3, so that the polishing belt 19 is supported by the L-shaped bracket 2. The part of the polishing belt 19 that is supported is flat, and its contact with the part is point contact, so that the middle part of the polishing belt 19 can be used for point polishing of the part; while the two ends of the polishing belt 19 are relatively soft. When the part approaches the polishing belt 19 with a certain force, the polishing belt 19 will deform with the shape of the part, and surface polishing can be performed.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
