Description

Technical Field

[0001] The utility model relates to the physical characteristics of a grinding body or a grinding plate, such as a grinding surface with special properties; the technical field of component characteristics of a grinding body or a grinding plate, and particularly to a quick-installation ultra-thin cutting disc. Background Art

[0002] Angle grinder, also known as grinding machine or disc grinder, is a kind of grinding tool used for cutting and grinding fiberglass. Angle grinder is a portable electric tool that uses fiberglass for cutting and grinding. It is mainly used for cutting, grinding and brushing metal and stone. Angle grinder is generally used together with its ultra-thin cutting disc.

[0003] Ultra-thin cutting blades belong to grinding wheels. They are made of abrasives and binder resins, etc. and are used to cut thin blades of ordinary steel, stainless steel, and non-metallic materials. They are divided into resin cutting blades and diamond cutting blades. Common ultra-thin cutting blades are installed on angle grinders using a larger cylinder with a threaded column. The cylinder limits the positional relationship between the ultra-thin cutting blade and the angle grinder, and the threaded column enables the cylinder and its output shaft to rotate synchronously. Each time an ultra-thin cutting blade is installed, the cylinder needs to be completely disassembled before the ultra-thin cutting blade can be installed. There is a possibility of loss after it is disassembled. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a quick-install ultra-thin cutting blade, which can solve the problem of possible loss of parts after the blade is disassembled.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-install ultra-thin cutting blade, comprising an angle grinder handle, the surface of which is fixedly mounted with an angle grinder body, the output end of which is fixedly sleeved with an output shaft, and the surface of the output shaft is provided with an installation limit device capable of quickly installing the ultra-thin cutting blade;

[0006] The installation limit device includes a limit shaft, the surface of the limit shaft is fixedly connected to the surface of the output shaft, the surface of the limit shaft is slidably connected to an annular body, and the surface of the annular body is fixedly connected to two stoppers;

[0007] Wherein, a bottom ring is fixedly sleeved on the surface of the output shaft.

[0008] Preferably, a threaded hole is provided on the surface of the limiting shaft, and a threaded column is connected to the inner thread of the threaded hole.

[0009] Preferably, the surface of the threaded column is fixedly connected to a limiting body, the surface of the limiting body is in contact with the surface of the annular body, and the interior of the limiting body is in contact with the surface of the limiting shaft;

[0010] A semicircular baffle is fixedly connected to the lower surface of the angle grinder body.

[0011] Preferably, a power transmission line is fixedly connected to the surface of the angle grinder handle, and a plug is fixedly connected to the other end of the power transmission line.

[0012] Preferably, an ultra-thin cutting blade is arranged on the outside of the angle grinder handle, and a mounting ring is fixedly connected to the inside of the ultra-thin cutting blade, and the surface of the mounting ring is in contact with the surface of the bottom ring.

[0013] Preferably, a mounting hole is provided on the surface of the mounting ring, the interior of the mounting hole contacts the surface of the output shaft, and the surfaces of the two stoppers contact the surface of the mounting ring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The quick-install ultra-thin cutting disc is installed by setting two blocks in the limit device. The limit body drives the annular body to move, thereby driving the two blocks to be in close contact with its mounting ring, so as to achieve the effect of installing the ultra-thin cutting disc. During the entire installation process, the ultra-thin cutting disc only needs to be directly installed on the surface of the output shaft, and there is no need to remove the limit body from the output shaft, thereby avoiding the possibility of losing the limit body.

[0016] 2. The general installation process of the quick-mounted ultra-thin cutting blade requires first disassembling the limiting device, then driving the ultra-thin cutting blade to install it in the hole, and then tightening it. However, by limiting the ultra-thin cutting blade with two blocks, the ultra-thin cutting blade can be directly installed, and then the two blocks are rotated to misalign with the installation hole, and then the limiting body is tightened. The disassembly process is replaced by rotating the two blocks to misalign them with the installation hole. In actual operation, the latter is simpler and more direct, and there is no need to worry about disassembling parts. Moreover, rotating the two blocks requires less effort than disassembling the limiting body, so this installation method is simpler.

[0017] 3. The quick-mounted ultra-thin cutting blade is likely to generate many sparks when cutting materials. In order to reduce the possibility of the sparks injuring the user, a semicircular baffle is provided to shield part of the ultra-thin cutting blade so that when the sparks generated by the ultra-thin cutting blade splash the operator, the semicircular baffle is used to shield and block them, thereby reducing the possibility of the sparks injuring the user.

[0029] See also Figure 1-5The utility model provides a technical solution: a quick-install ultra-thin cutting blade, comprising an angle grinder handle 3, an angle grinder body 4 is fixedly mounted on the surface of the angle grinder handle 3, an output shaft 7 is fixedly sleeved on the output end of the angle grinder body 4, and an installation limit device capable of quickly installing the ultra-thin cutting blade is provided on the surface of the output shaft 7;

[0030] The installation limit device includes a limit shaft 8, the surface of the limit shaft 8 is fixedly connected to the surface of the output shaft 7, the surface of the limit shaft 8 is slidably connected to an annular body 13, and the surface of the annular body 13 is fixedly connected to two stoppers 10;

[0031] The surface of the output shaft 7 is fixedly sleeved with a bottom ring 6 .

[0032] A threaded hole 16 is formed on the surface of the limiting shaft 8 , and a threaded column 12 is threadedly connected inside the threaded hole 16 .

[0033] The surface of the threaded column 12 is fixedly connected to the limiting body 11, the surface of the limiting body 11 contacts the surface of the annular body 13, and the interior of the limiting body 11 contacts the surface of the limiting shaft 8;

[0034] A semicircular baffle 5 is fixedly connected to the lower surface of the angle grinder body 4 .

[0035] A power transmission line 2 is fixedly connected to the surface of the angle grinder handle 3 , and a plug 1 is fixedly connected to the other end of the power transmission line 2 .

[0036] An ultra-thin cutting blade 14 is disposed outside the angle grinder handle 3 , and a mounting ring 15 is fixedly connected inside the ultra-thin cutting blade 14 , and the surface of the mounting ring 15 contacts the surface of the bottom ring 6 .

[0037] A mounting hole 9 is formed on the surface of the mounting ring 15 . The interior of the mounting hole 9 contacts the surface of the output shaft 7 . The surfaces of the two stoppers 10 contact the surface of the mounting ring 15 .

[0038] When the ultra-thin cutting blade 14 needs to be installed, the ultra-thin cutting blade 14 is driven to move by external force, and the movement of the ultra-thin cutting blade 14 drives the mounting ring 15 to move, and the movement of the mounting ring 15 drives the mounting hole 9 to move until it contacts the surface of the output shaft 7, and then the annular body 13 is rotated to drive the two blocks 10 so that both of them contact the surface of the mounting ring 15, and then the threaded column 12 is driven to move along the inside of the threaded hole 16 by rotating the limiting body 11, and finally the limiting body 11 squeezes the annular body 13 to drive the two blocks 10 to clamp the mounting ring 15 in cooperation with the bottom ring 6, thereby achieving the effect of clamping the ultra-thin cutting blade 14.

[0039] When the ultra-thin cutting blade 14 needs to be removed, it is only necessary to loosen the limiting body 11 so that the limiting body 11 is not in close contact with the annular body 13, and then rotate the ultra-thin cutting blade 14 by external force so that its mounting hole 9 and its two blocks 10 coincide with each other, and the ultra-thin cutting blade 14 can be removed.

[0040] By setting up two blocks 10 in the installation limit device, the annular body 13 is driven to move through its limit body 11, thereby driving the two blocks 10 to be in close contact with its mounting ring 15, so as to achieve the effect of installing the ultra-thin cutting blade 14. During the entire installation process, it is only necessary to directly install the ultra-thin cutting blade 14 to the surface of the output shaft 7, and there is no need to remove the limit body 11 from the output shaft 7, thereby avoiding the possibility of losing the limit body 11.

[0041] The general installation process requires first disassembling the limiting device, then driving the ultra-thin cutting blade to install it in the hole, and then tightening it. By limiting the ultra-thin cutting blade 14 with two blocks 10, the ultra-thin cutting blade 14 can be directly installed, and then the two blocks 10 are rotated to be misaligned with the mounting hole 9, and then the limiting body 11 is tightened. The disassembly process is replaced by rotating the two blocks 10 to make them misaligned with the mounting hole 9. The latter is simpler and more direct in actual operation, and there is no need to worry about disassembling parts. Moreover, rotating the two blocks 10 requires less effort than disassembling the limiting body 11, so this installation method is simpler.

[0042] When the ultra-thin cutting blade 14 is cutting materials, it is easy to generate many sparks. In order to reduce the possibility of the sparks injuring the user, a semicircular baffle 5 is provided to shield part of the ultra-thin cutting blade 14 so that when the sparks generated by the ultra-thin cutting blade 14 are splashed at the operator, the semicircular baffle 5 is used to shield and block them, thereby reducing the possibility of the sparks injuring the user.

[0043] Working principle: when the ultra-thin cutting blade 14 needs to be installed, the ultra-thin cutting blade 14 is driven to move by external force, the movement of the ultra-thin cutting blade 14 drives the mounting ring 15 to move, the movement of the mounting ring 15 drives the mounting hole 9 to move until it contacts the surface of the output shaft 7, and then the annular body 13 is rotated to drive the two blocks 10 so that both of their blocks 10 contact the surface of the mounting ring 15, and then the threaded column 12 is driven to move along the inside of the threaded hole 16 by rotating the limiting body 11, and finally the limiting body 11 squeezes the annular body 13 to drive the two blocks 10 to clamp the mounting ring 15 in cooperation with the bottom ring 6.

[0044] When the ultra-thin cutting blade 14 needs to be disassembled, it is only necessary to loosen the limiting body 11 so that the limiting body 11 is not in close contact with the annular body 13, and then rotate the ultra-thin cutting blade 14 by external force so that its mounting hole 9 and its two stoppers 10 overlap.
