Abstract
Description
Technical Field
[0001] This utility model belongs to the field of polishing machine technology, and in particular relates to a polishing machine angle adjustment mechanism. Background Technology
[0002] Polishing machines are commonly used for mechanical grinding, polishing, and waxing. The working principle of a polishing machine is as follows: an electric motor drives a sponge or wool polishing disc mounted on the polishing machine to rotate at high speed. Due to the combined action of the polishing disc and polishing agent and the friction with the surface to be polished, the purpose of removing paint contamination, oxidation layer, and shallow scratches can be achieved.
[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: the polishing mechanism (polishing motor and polishing disc) on the current polishing machine usually does not have a mechanism for adjusting its angle. The polishing mechanism can only polish in a specified position, resulting in a limited polishing range. Some polishing machines have an angle adjustment function, but their stability cannot be guaranteed when the polishing mechanism is not in use.
[0004] To address this issue, we propose a polishing machine angle adjustment mechanism. Summary of the Invention
[0005] The main purpose of this utility model is to provide a polishing machine angle adjustment mechanism. The angle adjustment motor can run and drive the polishing motor and polishing disc to rotate, so as to realize the free adjustment of the angle, thereby increasing the polishing range and making it suitable for more processing scenarios. When the polishing disc is not in use, it is positioned by two L-shaped positioning plates, and the structure remains stable and will not shake or fall. This can effectively solve the problems in the background technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A polishing machine angle adjustment mechanism includes a support plate and an angle adjustment module disposed on the support plate. The support plate is U-shaped, and a mounting plate is integrally welded to one side wall of the support plate. The angle adjustment module includes an angle adjustment motor horizontally mounted on the mounting plate, an inner support shaft coaxially connected to the output shaft of the angle adjustment motor, and an angle adjustment seat welded to the inner support shaft. A machine base is fixedly welded on the angle adjustment seat, and a polishing motor is mounted on the machine base. The output shaft of the polishing motor is coaxially connected to a polishing disc.
[0008] Bases are symmetrically welded on both sides of the bottom wall of the support plate. A cylinder is installed on the opposite side of the two bases. An inner contraction groove is formed on the opposite side of the two cylinders. A connecting rod is connected to each of the two bases. An inner piston block is welded on the opposite side of the two connecting rods. An outer extension plate is welded on the opposite side of the two inner piston blocks. An L-shaped positioning plate is welded on the opposite side of the two outer extension plates. The two positioning plates limit the two sides of the bottom wall of the angle adjustment seat, so that the angle adjustment seat and its structure remain stable.
[0009] As a preferred embodiment, protruding seats are welded on both sides of the inner side of the support plate, and the inner support shaft is horizontally set inside the support plate, with both ends of the inner support shaft rotatably connected to the two protruding seats respectively; so that the inner support shaft can operate stably under the drive of the angle adjustment motor.
[0010] In a preferred embodiment, the two connecting rods are respectively horizontally arranged in the two inner contraction grooves and connected to the inner wall of the inner contraction grooves, so that the connecting rods can extend and retract stably.
[0011] In a preferred embodiment, all four side walls of the inner piston block are in contact with the inner wall of the inner contraction groove, and the inner piston block is always located within the inner contraction groove; this allows the inner piston block to move only in one direction without falling.
[0012] As a preferred embodiment, one end of the extension plate is located inside the inner contraction groove, and the other end extends out of the inner contraction groove, with the top and bottom walls of the extension plate fitting against the inner wall of the inner contraction groove; thus ensuring the structural stability of the extension plate.
[0013] As a preferred embodiment, gaskets are fixedly bonded to the inner sides of both positioning plates, and the gaskets abut against the angle adjustment seat; the gaskets can be made of rubber to provide cushioning between the angle adjustment seat and the positioning plates.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] The polishing machine's angle adjustment mechanism, by driving two cylinders to retract two connecting rods, releases the angle adjustment seat from its fixation, allowing the angle adjustment motor to run and drive the polishing motor and polishing disc to rotate, thus achieving free angle adjustment. This increases the polishing range and makes it suitable for more processing scenarios. When the polishing disc is not in use, it is positioned by two L-shaped positioning plates, maintaining structural stability and preventing shaking or sagging. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-3 A polishing machine angle adjustment mechanism includes a support plate 1 and an angle adjustment module disposed on the support plate 1. The support plate 1 is U-shaped, and an mounting plate 2 is integrally welded to one side wall of the support plate 1. The angle adjustment module includes an angle adjustment motor 3 horizontally mounted on the mounting plate 2, an inner support shaft 5 coaxially connected to the output shaft of the angle adjustment motor 3, and an angle adjustment seat 6 welded to the inner support shaft 5. Protrusion seats 4 are welded to both sides of the inner side of the support plate 1. The inner support shaft 5 is horizontally disposed inside the support plate 1, and both ends of the inner support shaft 5 are rotatably connected to the two protrusion seats 4 respectively, so that the inner support shaft 5 can operate stably under the drive of the angle adjustment motor 3. A machine base 7 is fixedly welded on the angle adjustment seat 6, and a polishing motor 8 is mounted on the machine base 7. The output shaft of the polishing motor 8 is coaxially connected to a polishing disc 9.
[0023] Bases 10 are symmetrically welded on both sides of the bottom wall of the support plate 1. Cylinders 11 are installed on the opposite sides of the two bases 10. Inner contraction grooves 12 are formed on the opposite sides of the two cylinders 11. Connecting rods 13 are connected to the two bases 10 respectively. The two connecting rods 13 are horizontally set in the two inner contraction grooves 12 and connected to the inner wall of the inner contraction grooves 12, so that the connecting rods 13 can extend and retract stably. Inner piston blocks 14 are welded on the opposite sides of the two connecting rods 13. The four side walls of the inner piston blocks 14 are all in contact with the inner wall of the inner contraction grooves 12, and the inner piston blocks 14 are always located in the inner contraction grooves 12, so that the inner piston blocks 14 can only move in one direction and will not fall.
[0024] Furthermore, an extension plate 15 is welded to one side of each of the two inner piston blocks 14 facing each other. One end of the extension plate 15 is located inside the inner contraction groove 12, and the other end extends out of the inner contraction groove 12. The top and bottom walls of the extension plate 15 are in contact with the inner wall of the inner contraction groove 12, thereby ensuring the structural stability of the extension plate 15. An L-shaped positioning plate 16 is welded to one side of each of the two extension plates 15 facing each other. A gasket 17 is fixedly bonded to the inner side of each of the two positioning plates 16, and the gasket 17 abuts against the angle adjustment seat 6. The gasket 17 can be made of rubber and serves as a buffer between the angle adjustment seat 6 and the positioning plate 16. The two positioning plates 16 respectively limit the two sides of the bottom wall of the angle adjustment seat 6, so that the angle adjustment seat 6 and its structure remain stable.
[0025] The polishing machine's angle adjustment mechanism works as follows: During operation, the polishing motor 8 drives the polishing disc 9 to rotate at high speed, allowing for the polishing of the workpiece. If angle adjustment of the polishing motor 8 and polishing disc 9 is required, first, the two cylinders 11 operate, causing the two connecting rods 13 to retract. This retracts the inner piston block 14 and the outer extension plate 15 into the inner retraction groove 12, and disengages the two positioning plates 16 from the angle adjustment seat 6. At this point, the angle adjustment motor 3 is driven to rotate the inner support shaft 5 and the angle adjustment seat 6, along with the polishing motor 8 and polishing disc 9, to adjust their angles. Of course, the actual orientation of the polishing motor 8 and polishing disc 9 can be determined according to the attached... Figure 1 The position shown is rotated horizontally by 90°, allowing the polishing motor 8 and polishing disc 9 to achieve a different style of flipping during rotation to meet different needs.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
