Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically to an electric grinding and polishing machine. Background Technology

[0002] In machining workshops, the surface treatment of precision workpieces (such as grinding and polishing) requires extremely high smoothness, directly affecting the assembly accuracy and performance of the workpieces. Traditional methods mainly rely on manual operation of handheld angle grinders or ordinary polishing equipment, which suffers from low efficiency, unstable processing quality, and high labor intensity for workers. In addition, due to the uncontrollability of manual operation, the workpiece surface is easily scratched or over-polished, affecting the yield. Therefore, there is an urgent need for a special grinding and polishing equipment that is easy to operate and highly adaptable to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. 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.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: an electric grinding and polishing machine, including a body 1, a support frame 2 mounted on the front side of the body 1, mounting grooves 3 on both the upper and lower sides of the support frame 2, and a support shaft 4 mounted in each of the two mounting grooves 3. The mounting grooves 3 are vertical strip grooves, and the support shafts 4 can be installed in different positions within the mounting grooves 3. If it is necessary to adjust the tension of the abrasive belt 8, the position of the support shaft 4 can be moved through the mounting grooves 3 after the machine is stopped. Support wheels 5 are mounted on both support shafts 4. A drive motor 6 is installed inside the body 1. The drive motor 6 has a power of 2.2KW and a speed of 1400r / min. The output of the drive motor 6 is located at the middle. A drive wheel 7 is installed, and the drive wheel 7 and the two support wheels 5 are arranged in a triangle. A sanding belt 8 is connected between the drive wheel 7 and the two support wheels 5. Limiting rings are provided on both sides of the drive wheel 7 and the two support wheels 5, and the sanding belt 8 is limited on both sides by the limiting rings. A grinding platform 9 is slidably installed on the front side of the machine body 1, and the grinding platform 9 is directly opposite the sanding belt 8. The front part of the sanding belt 8, which is connected between the drive wheel 7 and the two support wheels 5, is set vertically. The workpiece to be processed is placed stably on the grinding platform 9, ensuring that its surface is in complete contact with the front part of the vertically set sanding belt 8. A pressure adjustment handwheel is installed on the machine body 1. 11. A threaded rod 111 is connected to the pressure adjusting handwheel 11. The threaded rod 111 is installed inside the machine body 1 via a bearing. The threaded rod 111 is connected to a threaded groove at one end of the linkage plate 112. The linkage plate 112 has a slot at its head and slides on the slide plate 113. The slide plate 113 is installed inside the machine body 1. The other end of the linkage plate 112 is fixedly installed at the bottom of the grinding platform 9. By rotating the pressure adjusting handwheel 11, the threaded rod 11 is rotated. The threaded rod 11, through its connection with the threaded groove on the linkage plate 112, can drive the linkage plate 112 to slide on the slide plate 113, thereby moving the grinding platform 9. At the same time, the workpiece placed on the grinding platform 9 is relatively large. The platform itself is stable. When adjusting the position of the grinding platform 9, the contact pressure between the workpiece and the abrasive belt 8 can be finely adjusted. The grinding platform 9 is directly opposite the vertical section in front of the abrasive belt 8. The control panel 10 is installed on the front of the machine body 1 to control and indicate the power of the drive motor 6. When the power of the control panel 10 is turned on, the drive motor 6 is started. The abrasive belt 8 starts to run under the transmission of the drive wheel 7 and the support wheel 5. The workpiece moves at a uniform speed along the grinding platform 9 to maintain uniform force and avoid local over-polishing or under-polishing. After processing is completed, the drive motor 6 is turned off and the abrasive shavings on the grinding platform 9 and the abrasive belt 8 are cleaned.

[0021] The operational steps for this application are as follows:

[0022] Place the workpiece to be processed stably on the grinding platform 9, ensuring that its surface is in full contact with the front section of the vertically set abrasive cloth belt 8; finely adjust the contact pressure between the workpiece and the abrasive cloth belt 8 by adjusting the pressure adjustment handwheel 11.

[0023] Turn on the power of the control panel 10, start the drive motor 6, and the sanding cloth belt 8 will start to run under the transmission of the drive wheel 7 and the support wheel 5; move the workpiece at a uniform speed along the grinding platform 9 to maintain uniform force and avoid local over-polishing or under-polishing.

[0024] Observe the processing effect. If it is necessary to adjust the tension of the abrasive belt 8, the position of the support shaft 4 can be moved through the mounting groove 3 after the machine is stopped. After the processing is completed, turn off the drive motor 6 and clean the grinding platform 9 and the abrasive belt 8.
