Abstract
Description
Technical Field
[0001] This invention belongs to the field of angle grinder technology, specifically relating to a platform-based angle grinder fixing and grinding angle adjustment device. Background Technology
[0002] Traditional angle grinders are handheld, making it difficult to control the grinding angle and resulting in poor grinding stability. They also require the user to be close to the surface, limiting their use in poorly accessible locations. While angle grinders with extended handles are available, these still remain handheld, failing to address the issues of angle control and stability. Therefore, a platform-based angle grinder fixing and grinding angle adjustment device needs to be developed. Summary of the Invention
[0003] The purpose of this invention is to provide a platform-based angle grinder fixing and grinding angle adjustment device, which can expand the application scenarios of the angle grinder.
[0004] The technical solution of the present invention is as follows: A platform-based angle grinder fixing and grinding angle adjustment device, including a platform, an angle adjustment device, and a grinding head lifting device. The platform is provided with mounting threaded holes or through holes. When combined with machine tool tools, it is provided with mounting threaded holes for fixing the angle adjustment device and the grinding head lifting device by bolts.
[0005] The angle adjustment device includes a hinge device and a fixing device. The hinge device has a threaded hole and is fixed to the platform by bolts. The rotating part of the hinge is fastened to the fixing device by bolts. The fixing device is used to fix the position of the angle grinder handle. When the rotating part of the hinge rotates, it can drive the fixing device to rotate, thereby driving the angle grinder handle to rotate.
[0006] The grinding head lifting device has rectangular through holes on both wings, and long bolts passing through the through holes are tightened downwards into threaded holes on the platform.
[0007] Each of the two rectangular through holes on the wings is equipped with a movable nut at the top and bottom. The height of the grinding head lifting device can be adjusted by adjusting the position of the nut on the bolt.
[0008] The movable nut includes an upper adjusting nut and a lower adjusting nut. The upper adjusting nut and the lower adjusting nut can move up and down the adjusting bolt to adjust the height of the two wings of the lower support relative to the platform, thereby adjusting the height of the lower support relative to the platform and realizing the adjustment of the grinding angle of the angle grinder head.
[0009] The grinding head lifting device has two through holes, through which bolts are screwed into the handle holes on the grinding head of the angle grinder for fastening.
[0010] The beneficial effects of the present invention are as follows: the present invention can fix the grinder on the platform and adjust the grinding angle of the grinder. By combining the platform with other tools, the application scenarios of the grinder are expanded and the grinding quality of the grinder is improved. Attached Figure Description

Detailed Implementation
[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] The present invention provides a platform-based angle grinder fixing and grinding angle adjustment device, including a platform, an angle adjustment device, and a grinding head lifting device. The platform is provided with mounting threaded holes or through holes. When combined with machine tool tools, it is provided with mounting threaded holes for fixing the angle adjustment device and the grinding head lifting device by bolts.
[0016] The angle adjustment device includes a hinge device and a fixing device. The hinge device has a threaded hole and is fixed to the platform by bolts. The rotating part of the hinge is fastened to the fixing device by bolts. The fixing device is used to fix the position of the angle grinder handle. When the rotating part of the hinge rotates, it can drive the fixing device to rotate, thereby driving the angle grinder handle to rotate.
[0017] The grinding head lifting device has rectangular through holes on both wings, and long bolts passing through the through holes are tightened downwards into threaded holes on the platform.
[0018] Each of the two rectangular through holes on the wings is equipped with a movable nut at the top and bottom. The height of the grinding head lifting device can be adjusted by adjusting the position of the nut on the bolt.
[0019] Specifically, such as Figure 1 and 2As shown, a platform-based angle grinder fixing and grinding angle adjustment device includes a platform 1, a hinge fixing device 2, a lifting fixing device 3, an angle grinder 4, a hinge fixing part 21, a hinge rotating part 22, an angle grinder corner fixing part 23, a bolt connecting the angle grinder corner fixing part and the hinge 24, an upper bracket for the angle grinder 25, a fixing stainless steel strip 26, an upper fixing bolt for the angle grinder 27, an upper fastening nut for the angle grinder 28, a lower bracket 31, two wings of the lower bracket 32, an adjusting bolt 33, an upper adjusting nut 34, a lower adjusting nut 35, and an angle grinder fixing bolt 36.
[0020] Threaded holes are drilled at appropriate locations on platform 1 for installing the fastening bolts below 21 and the adjusting bolts 33. The hinge fixing part 21 and the adjusting bolts are fixed to the platform by bolts.
[0021] The hinge rotating part 22 is provided with a threaded hole, and the angle grinder corner fixing part 23 is provided with a through hole. It is fixed to the hinge connecting bolt 24 by the angle grinder corner fixing part and can rotate together with the hinge rotating part 22.
[0022] The upper fastening nut 28 of the angle grinder is fixed to the upper bracket 25 of the angle grinder by welding. The upper part of the angle grinder is fixed to the upper bracket 25 of the angle grinder by the upper fixing bolts 27 and the fixing stainless steel band 26. When the angle grinder's corner fixing part 23 rotates, the upper bracket 25 of the angle grinder rotates along with it, driving the entire angle grinder to rotate.
[0023] The lower support 31 of the angle grinder has a through hole, which can be fastened to the threaded hole of the angle grinder's handle using the angle grinder fixing bolt 36. The two wings 32 of the lower support have rectangular through holes, allowing the adjusting bolt 33 to move along the length of these through holes when the angle grinder rotates. The upper adjusting nut 34 and lower adjusting nut 35 can be moved up and down by the adjusting bolt 33 to adjust the height of the two wings 32 of the lower support relative to the platform 1, thereby adjusting the height of the lower support 31 relative to the platform 1 and achieving adjustment of the grinding angle of the angle grinder head.
[0024] In practice, the device is installed on the machine tool through the mounting holes on the platform. The angle between the grinding head and the grinding surface can be changed by adjusting the position of the upper adjusting nut 34 and the lower adjusting nut 35 on the adjusting bolt 33 according to the distance from the surface to be ground, so as to achieve stable grinding under the premise of controllable angle.
