Description

Technical Field

[0001] This application relates to the field of polishing equipment technology, and in particular to a polishing machine for improving polishing brightness. Background Technology

[0002] In modern industrial production, polishing machines are commonly used equipment for processing the surfaces of various workpieces. However, existing polishing machines generally have some obvious defects;

[0003] Firstly, the fixed angle of the polishing machine makes it difficult to achieve the ideal contact angle between the polishing tool and the workpiece surface when polishing some workpieces with complex shapes and irregular surfaces, resulting in uneven polishing and affecting polishing quality and efficiency.

[0004] Secondly, a large amount of dust is generated during the polishing process. This dust easily flies in the working environment. On the one hand, the dust pollutes the workplace and increases the cost of cleaning and maintenance. On the other hand, long-term exposure to this environment may cause damage to the respiratory system and other systems of operators, seriously threatening their health. Therefore, a polishing machine that improves polishing brightness is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a polishing machine that improves polishing brightness. By improving its structural design, it solves the problems of fixed angle and dust pollution in existing polishing machines, thereby improving polishing quality and the safety of the working environment.

[0006] The polishing machine for improving polishing brightness provided in this application adopts the following technical solution:

[0007] A polishing machine for improving polishing brightness includes a worktable, a gantry frame installed on the outer wall of the worktable, a movable seat installed on the outer wall of the gantry frame, and a hydraulic cylinder fixedly installed on the outer wall of the movable seat. The output end of the hydraulic cylinder is fixedly connected to a fixed plate. The bottom outer wall of the fixed plate is connected to a flange through an angle adjustment mechanism. A drive motor is fixedly installed on the bottom outer wall of the flange. A polishing wheel is fixedly connected to the end of the output shaft of the drive motor. A protective dust collection component is installed on the outside of the polishing wheel.

[0008] The angle adjustment mechanism includes a rotating disk rotatably connected to the bottom outer wall of a fixed disk via multiple connecting blocks. A worm gear is rotatably connected to the bottom outer wall of the rotating disk via two fixed blocks. A mounting frame is fixedly connected to the bottom end of the two fixed blocks.

Both ends of the rotating shaft pass through the mounting frame and are fixedly connected to rotating frames. A flange is fixedly connected to the bottom end of the two rotating frames.

[0009] Preferably, the angle adjustment mechanism further includes a second bevel gear fixedly connected to the outer wall of the top of the rotating disk, a first motor is fixedly installed on the outer wall of the fixed disk, and the output shaft of the first motor is fixedly connected to the first bevel gear, the first bevel gear meshing with the second bevel gear.

[0010] Preferably, a second motor is fixedly mounted on the outer wall of one of the fixing blocks, and the end of the output shaft of the second motor passes through the fixing block and is fixedly connected to one end of the worm gear.

[0011] Preferably, the protective dust collection assembly includes a mounting cover fixedly connected to the outer wall of the drive motor. A fixing ring is fixedly connected to the bottom outer wall of the mounting cover. A protective cover is adhered to the bottom outer wall of the fixing ring.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a polishing machine for improving polishing brightness. (Refer to...) Figure 1-4 A polishing machine for improving polishing brightness includes a worktable 1, which is made of high-strength steel and its surface is precision machined to ensure good flatness and stability and can withstand a large weight. Two parallel guide rails are set on the top of the worktable 1. The guide rails are high-precision linear guide rails with low friction, high rigidity and high positioning accuracy.

[0023] The gantry 2 is equipped with pulleys on both sides that match the guide rails. The pulleys are firmly connected to the gantry 2 by bolts. Through the cooperation of the pulleys and the guide rails, the gantry 2 can move back and forth on the worktable 1. In order to drive the gantry 2 to move, a drive component (not shown in the figure) can be installed on the gantry 2. Driving the pulleys to rotate will drive the gantry 2 to move. This is existing technology and will not be described in detail.

[0024] The movable seat 3 is installed on the outer wall of the gantry frame 2. The gantry frame 2 is provided with a vertical guide rail. The movable seat 3 is equipped with a pulley that cooperates with the guide rail, so that the movable seat 3 can move left and right on the gantry frame 2. The movement of the movable seat 3 can also be achieved by installing a drive component (not shown in the figure) to drive the pulley to rotate.

[0025] The hydraulic cylinder 4 is fixedly installed at the center of the outer wall of the movable seat 3. Its output end is fixedly connected to the fixed plate 6 through a high-strength connector. The hydraulic cylinder 4 is a high-precision, high-thrust model. In conjunction with the external hydraulic system (not shown in the figure), it can accurately control the vertical lifting and lowering of the fixed plate 6 to meet the polishing requirements of workpieces of different heights.

[0026] The fixed plate 6 is a circular metal plate with sufficient strength and rigidity to support the subsequent angle adjustment mechanism and other components. The components of the angle adjustment mechanism are installed as follows:

[0027] Multiple connecting blocks 7 are evenly distributed on the bottom outer wall of the fixed disk 6. The connecting blocks 7 are made of high-strength alloy material and are connected to the fixed disk 6 by bolts. The rotating disk 8 is rotatably connected to the fixed disk 6 through the connecting blocks 7. The rotating disk 8 can rotate 360 ​​degrees relative to the fixed disk 6 in the horizontal direction.

[0028] The bottom outer wall of the rotating disk 8 is rotatably connected to the worm 24 through two fixed blocks 9. The fixed blocks 9 are also made of high-strength alloy material, which has good rigidity and wear resistance. The two ends of the worm 24 are connected to the two fixed blocks 9 through high-precision bearings to ensure that the worm 24 can rotate flexibly.

[0029] The bottom ends of the two fixing blocks 9 are fixedly connected to the mounting frame 10 by welding or bolting. The mounting frame 10 is a frame structure used to support and fix the worm wheel 23. The outer wall of the middle section of the mounting frame 10 is rotatably connected to the worm wheel 23 through a high-precision rotating shaft. The two ends of the rotating shaft are fixed to the mounting frame 10 by bearings. The worm wheel 23 meshes with the worm 24. When the worm 24 rotates, it can drive the worm wheel 23 to rotate around the rotating shaft.

[0030] Both ends of the rotating shaft pass through the mounting bracket 10 and are fixedly connected to the rotating bracket 11 by key connection or other fixing methods. The bottom end of the rotating bracket 11 is fixedly connected to the flange 12, so that the flange 12 can change the tilt angle as the worm gear 23 rotates.

[0031] A second bevel gear 22 is fixedly connected to the top outer wall of the rotating disk 8. The second bevel gear 22 is made of high-quality steel and is heat-treated to improve its hardness and wear resistance. A first motor 20 is fixedly installed on the outer wall of the fixed disk 6. The first motor 20 is selected to have sufficient torque and speed. A first bevel gear 21 is fixedly connected to the end of the output shaft of the first motor 20. The first bevel gear 21 meshes with the second bevel gear 22. When the first motor 20 starts, it can drive the first bevel gear 21 to rotate, and then the rotating disk 8 is rotated in the horizontal direction through the second bevel gear 22.

[0032] A second motor 25 is fixedly installed on the outer wall of one of the fixed blocks 9. The second motor 25 is also selected with appropriate torque and speed. The end of the output shaft of the second motor 25 passes through the fixed block 9 and is fixedly connected to one end of the worm gear 24 through a coupling. When the second motor 25 starts, it can drive the worm gear 24 to rotate, thereby realizing the tilt angle adjustment of the worm wheel 23, the rotating frame 11, the flange 12 and subsequent components.

[0033] The drive motor 13 is fixedly installed on the bottom outer wall of the flange 12. The drive motor 13 is a high-speed, high-power model that can provide sufficient rotational power for the polishing wheel 14. The polishing wheel 14 is fixedly connected to the end of the output shaft of the drive motor 13 by key connection or other fixing methods. The material and type of the polishing wheel 14 can be selected according to different polishing needs, such as sandpaper wheel, wool wheel, etc.

[0034] Protective dust collection component: The mounting cover 15 is fixedly connected to the outer wall of the drive motor 13. The mounting cover 15 is a metal cover with certain strength and protective performance. A fixing ring 16 is fixedly connected to the bottom outer wall of the mounting cover 15. The fixing ring 16 is a circular metal ring used to fix the protective cover 17.

[0035] The protective cover 17 is made of a transparent or semi-transparent flexible wear-resistant material, such as polyurethane elastomer, and is fixed to the bottom outer wall of the fixing ring 16 by adhesive. A sealing ring 18 is bonded to the bottom end of the protective cover 17. The sealing ring 18 is made of rubber or other elastic material, which can enhance the sealing performance between the protective cover 17 and the workpiece surface and prevent dust leakage.

[0036] A spring 19 is installed between the sealing ring 18 and the fixing ring 16. The springs 19 are evenly distributed on the outer circumference of the protective cover 17. The elastic force of the springs 19 can make the protective cover 17 fit the workpiece surface better, and at the same time play a buffering role during the polishing process.

[0037] The industrial vacuum cleaner 5 is installed on the outer wall of the movable base 3. The industrial vacuum cleaner 5 is selected with sufficient suction power and capacity. The suction head 26 is set on the bottom inner wall of the mounting cover 15. The shape and position design of the suction head 26 can effectively collect the dust generated during the polishing process. The suction pipe 27 is made of flexible wear-resistant material. One end of it is connected to the suction end of the industrial vacuum cleaner 5, and the other end is connected to the suction head 26 to ensure smooth dust delivery during the vacuuming process.

[0038] The implementation principle of a polishing machine for improving polishing brightness according to an embodiment of this application is as follows: the workpiece to be polished is placed on the worktable 1, and the workpiece is fixed in a suitable position using a clamp or other positioning device (not shown in the figure) according to the shape and size of the workpiece to ensure that the workpiece does not move during the polishing process.

[0039] Start the drive unit on the gantry 2 to move the gantry 2 back and forth on the worktable 1 and adjust the gantry 2 to the appropriate position of the workpiece to be polished;

[0040] By moving the movable seat 3 on the gantry 2 and extending and retracting the hydraulic cylinder 4, the polishing wheel 14 is adjusted to a position close to the part of the workpiece to be polished.

[0041] According to the angle and direction of the workpiece surface to be polished, the first motor 20 is started. The first motor 20 drives the first bevel gear 21 to rotate, and through the second bevel gear 22, the rotating disk 8 is rotated in the horizontal direction to adjust the horizontal angle of the polishing wheel 14.

[0042] Start the second motor 25, which drives the worm gear 24 to rotate. The tilt angle of the polishing wheel 14 is adjusted by the worm wheel 23, the rotating frame 11 and the flange 12, so that the polishing wheel 14 can better fit the surface of the workpiece to be polished.

[0043] After the position and angle of the polishing wheel 14 are adjusted, the drive motor 13 is started. The drive motor 13 drives the polishing wheel 14 to rotate at high speed to polish the workpiece. At the same time, the industrial vacuum cleaner 5 is started. The industrial vacuum cleaner 5 sucks in the dust generated during the polishing process through the suction pipe 27 and the suction head 26. After being filtered and collected by the industrial vacuum cleaner 5, the dust is stored in the dust collection box of the industrial vacuum cleaner 5, thereby keeping the working environment clean.

[0044] During the polishing process, operators can observe the polishing effect of the workpiece and the operating status of the equipment, and adjust parameters such as the position of the gantry 2, the position, angle, and speed of the polishing wheel 14, as well as the suction power of the industrial vacuum cleaner 5 in real time to ensure the best polishing brightness and quality.

[0045] 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.
