Description

Technical Field

[0001] This application relates to the field of workpiece polishing technology, and in particular to a polishing mechanism for workpiece surfaces. Background Technology

[0002] Currently, a polishing machine is a device used to perform surface finishing on workpieces. It mainly removes surface defects such as burrs, scratches, and oxide layers through mechanical, chemical, or electrochemical methods to improve surface smoothness, gloss, or achieve specific gloss effects (such as mirror finish or matte finish).

[0003] There are various types of workpiece surface polishing machines available, which can be selected according to needs: rotary polishing machines, vibratory polishing machines, magnetic polishing machines, electrolytic polishing machines, sandblasting polishing machines, drum polishing machines, laser polishing machines, and CNC polishing machines. The selection should be based on a comprehensive consideration of the workpiece material, shape, precision requirements, and production volume.

[0004] A Chinese patent with publication number CN111482872B discloses a workpiece surface polishing device, including a working platform with multiple clamping mechanisms installed on it. A polishing assembly is mounted above the working platform, and a pressure roller is also mounted above it. The pressure roller is used to press down the polishing belt of the polishing assembly. Symmetrically distributed pressure roller support seats are fixedly installed at the upper end of the working platform, with the symmetrically distributed pressure roller support seats located at both ends of the pressure roller. A slidingly connected pressure roller drive mechanism is provided on the pressure roller support seats. A limit cylinder support plate is fixedly installed on the outer side of the upper end of the buffer sleeve, and a pressure roller limit cylinder is fixedly installed on the limit cylinder support plate. At the same time, a pressure roller limit plate is fixedly installed at the lower end of the pressure roller drive slider, and a limit slot is formed on the pressure roller limit plate. This invention uses the pressure roller to press down the polishing belt, and the polishing belt gradually polishes the workpiece in the X / Y directions until the workpiece surface is polished.

[0005] In related technologies, the workpiece is fixed on the work platform by a clamping mechanism, and then the polishing assembly polishes the workpiece. After one side of the workpiece is polished, the workpiece is removed from the clamping mechanism, and then the workpiece is adjusted and re-clamped, and the polishing assembly polishes the workpiece again.

[0006] Regarding the aforementioned technologies, the inventors believe that after polishing one side of the workpiece, it is necessary to re-clamp the workpiece, which reduces the polishing efficiency of the workpiece. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a polishing mechanism for the surface of a workpiece, which solves the technical problem that after one side of the workpiece is polished, the workpiece needs to be re-clamped, which reduces the polishing efficiency of the workpiece.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A polishing mechanism for a workpiece surface includes: a frame for supporting the polishing mechanism; a clamping assembly rotatably mounted on the frame for clamping the workpiece; a support assembly mounted on the frame for supporting the workpiece; and a polishing assembly mounted on the frame for polishing the workpiece.

[0009] Furthermore, the clamping assembly includes a gripper and a clamping cylinder, the clamping cylinder being mounted on the frame and the gripper being mounted on the clamping cylinder.

[0010] Furthermore, the support assembly includes a lifting cylinder and a support plate. The lifting cylinder is mounted on the frame, and the support plate is mounted on the lifting cylinder. The support plate supports the workpiece.

[0011] Furthermore, the polishing assembly includes a polishing wheel that is slidably mounted on the frame and is used to polish the workpiece.

[0012] Furthermore, a first rotary motor is provided on the frame, the first rotary motor is mounted on the frame, and the clamping cylinder is mounted on the output shaft of the first rotary motor.

[0013] Furthermore, a material collection box is provided on the frame, a material collection trough is formed inside the material collection box, and an air extraction hole is provided on the material collection box, which is connected to the material collection trough.

[0014] Furthermore, a second rotary motor is provided on the frame, and the polishing wheel is mounted on the output shaft of the second rotary motor.

[0015] In summary, this application includes at least one of the following beneficial technical effects of a polishing mechanism for workpiece surfaces: The workpiece is clamped by the clamping assembly, then the support assembly supports the workpiece, and then the polishing assembly polishes the workpiece. After one side of the workpiece is polished, the clamping assembly drives the workpiece to rotate. After the workpiece rotates, the polishing assembly polishes the workpiece, thus eliminating the need to re-clamp the workpiece and improving the polishing efficiency of the workpiece. The stability of workpiece polishing is improved by setting up grippers, clamping cylinders, lifting cylinders, and support plates. The first rotating motor drives the clamping cylinder to rotate, and the second rotating motor drives the polishing wheel to rotate, which improves the convenience of workpiece polishing.

Detailed Implementation

[0018] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a polishing mechanism for workpiece surfaces.

[0021] Reference Figure 1 A polishing mechanism for workpiece surfaces includes a frame 1, on which a clamping assembly 2 and a supporting assembly 3 are mounted. The clamping assembly 2 clamps the workpiece, and the supporting assembly 3 supports the workpiece on the clamping assembly 2. A polishing assembly 4 is mounted on the frame 1 to polish the workpiece.

[0022] Reference Figure 2 The clamping assembly 2 includes a clamping cylinder 21 and a gripper 22. The gripper 22 is mounted on the clamping cylinder 21. In use, the clamping cylinder 21 drives the gripper 22 to clamp the workpiece. A first rotary motor 23 is provided on the frame 1 and is mounted on the output shaft of the first rotary motor 23. In use, the clamping cylinder 21 drives the gripper 22 to clamp the workpiece. After one side of the workpiece is polished, the first rotary motor 23 drives the clamping cylinder 21 to rotate, thereby allowing the workpiece to adjust its polishing angle during the polishing process and improving the polishing efficiency.

[0023] Reference Figure 3The polishing assembly 4 includes a polishing wheel 41, which is slidably mounted on a frame 1. A sliding frame 42 is provided on the frame 1, and a second rotary motor 43 is mounted on the sliding frame 42. The polishing wheel 41 is mounted on the output shaft of the second rotary motor 43. In use, the second rotary motor 43 drives the polishing wheel 41 to rotate, and during the rotation of the polishing wheel 41, the polishing wheel 41 polishes the workpiece.

[0024] Furthermore, the frame 1 is provided with a first slide rail 44, which is horizontally positioned and perpendicular to the direction of the gripper 22. A second slide rail 45 is provided on the first slide rail 44, which is vertically positioned, with one end of the second slide rail 45 slidably mounted on the first slide rail 44. A sliding frame 42 is mounted on the second slide rail 45. In use, the second slide rail 45 slides along the first slide rail 44 toward the side closer to the gripper 22, and the sliding frame 42 slides along the vertical direction of the second slide rail 45 toward the side closer to or away from the gripper 22. When the polishing wheel 41 on the sliding frame 42 is pressed against the workpiece, the second rotary motor 43 drives the polishing wheel 41 to rotate.

[0025] During the polishing process of the polishing wheel 41, pressure is usually applied to the workpiece to ensure that the polishing wheel 41 can polish it effectively. After prolonged use, the gripper 22 is easily bent by the polishing wheel 41, which affects the rotation of the gripper 22. To reduce the pressure of the polishing wheel 41 on the gripper 22, the support assembly 3 includes a lifting cylinder 31. The lifting cylinder 31 is vertically arranged, and a support plate 32 is mounted on the lifting cylinder 31. The support plate 32 is horizontally arranged and mounted on the lifting cylinder 31. When the gripper 22 clamps the workpiece, the lifting cylinder 31 drives the support plate 32 to rise, supporting the workpiece. When the polishing wheel 41 polishes the workpiece, the pressure of the workpiece acts on the support plate 32, thereby reducing the pressure on the gripper 22 and the clamping cylinder 21 when the polishing wheel 41 polishes the workpiece, thus extending the service life of the gripper 22 and the clamping cylinder 21.

[0026] A material collection box 11 is installed on the frame 1, located below the gripper 22. The top of the material collection box 11 is open, and a material collection trough 12 is formed inside the box. During use, burrs polished from the workpiece fall into the material collection trough 12 of the material collection box 11. Furthermore, an air extraction hole 13 is provided on the material collection box 11, which communicates with the material collection trough 12. During use, an external air extraction pipe is connected to the air extraction hole 13 on the material collection box 11. During the polishing process of the polishing wheel 41, the air extraction device extracts air, causing burrs to fall into the material collection box 11. Due to the air extraction device, the number of burrs falling outside the material collection box 11 during the polishing process of the polishing wheel 41 is reduced.

[0027] 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.
