Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and more specifically, it relates to an easily detachable grinding disc. Background Technology

[0002] A grinding disc is a mounting base used to apply or embed abrasive grains, allowing the abrasive grains to perform cutting action, and also serves as a shaping tool for the grinding surface. Rotating discs, cylinders, cones, flat plates, whetstones, thin plates, tubes, rings, and specially designed shaped grinding discs can all be used as grinding tools. Grinding discs are commonly used tools in machining, metal surface treatment, and other fields. After prolonged use, a grinding disc will wear down and need to be replaced promptly. However, currently, grinding discs are usually fixed by removing them from the surface using tools, which allows debris to easily enter the gaps in the grinding disc surface and damage the disassembly structure.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an easily disassembled grinding disc, in order to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an easily detachable grinding disc, which solves the problem that the current method of fixing grinding discs usually involves disassembling them on the surface of the grinding disc with the help of tools, and waste chips can easily enter the gaps on the surface of the grinding disc and damage the disassembly structure.

[0005] The purpose and function of this utility model, which provides an easily detachable grinding disc, are achieved through the following specific technical means:

[0006] A detachable grinding disc includes a mounting base, a grinding disc plate, and locking components. Multiple locking components are provided between the mounting base and the grinding disc plate. Each locking component includes a locking member, a locking rod, and a push rod. A cavity is formed at the bottom of the grinding disc, and a guide groove communicating with the cavity is formed inside the grinding disc. An operating hole communicating with the guide groove is formed on the side of the grinding disc. The locking member is set on the mounting base and slides through the cavity. A locking hole is formed on the locking member. A locking rod is set on the guide groove and slides through the locking hole. A push rod is set on one side of the locking rod and is set in the operating hole. The cavity and the operating hole are connected through the guide groove.

[0007] Furthermore, a spring is provided between the tail end of the locking rod and the inner wall of the guide groove, and the spring abuts against the locking rod when the locking rod extends into the lock hole.

[0008] Furthermore, a limiting groove is formed on the grinding disc, which is connected to the operating hole. When the grinding disc is disassembled, the push rod drives the locking rod out of the locking hole, and the push rod is pushed into the limiting groove so that the push rod is stuck in the limiting groove.

[0009] Furthermore, the surface of the grinding disc is provided with fish-scale-like grinding texture.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The grinding disc can be replaced with simple loading and unloading. The disassembly and assembly mechanism is located on the side of the grinding disc, so the waste generated during the grinding process will not get stuck in the disassembly and assembly mechanism. When assembling and fixing, insert the clip into the cavity and push the push rod to insert the locking rod into the lock hole to lock it in place. When disassembling, simply remove the locking rod from the lock hole. It can be installed and disassembled without the aid of tools, which is convenient and quick. Attached Figure Description

[0020] Example:

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides an easily detachable grinding disc, including a mounting base 1, a grinding disc 2, and a locking component 3. The mounting base 1 is mounted on the operating table and is used to connect the grinding disc 2 to the drive mechanism. The drive mechanism drives the mounting base 1 and the grinding disc 2 to rotate together, typically at a speed of 2400 revolutions per minute. The surface of the grinding disc 2 is provided with fish-scale-like abrasive texture 6, which makes it sharper when grinding materials. The locking component 3 is located between the mounting base 1 and the grinding disc 2 and is used to connect the mounting base 1 and the grinding disc 2.

[0023] The locking component 3 includes a locking member 301, a locking rod 302, and a push rod 303. The locking member 301 is mounted on the mounting base 1. A cavity 201 is opened at the bottom of the grinding plate 2. The locking member 301 slides through the cavity 201. A guide groove 202 communicating with the cavity 201 is opened inside the grinding plate 2. The locking rod 302 is mounted on the guide groove 202. A locking hole 4 is opened on the locking member 301. The locking rod 302 slides through the locking hole 4. The locking rod 302 is used to fix the mounting base 1 and the grinding plate 2. A push rod 303 is mounted at one end of the locking rod 302. An operating hole 203 communicating with the guide groove 202 is opened on the side of the grinding plate 2. The push rod 303 is mounted in the operating hole 203. A finger passes through the operating hole 203 to control the push rod 303. The cavity 201 and the operating hole 203 are connected through the guide groove 202.

[0024] A spring 5 is provided between the tail end of the locking rod 302 and the inner wall of the guide groove 202. During assembly, the locking rod 302 extends into the locking hole 4, and the spring 5 is in an extended state. At this time, the spring 5 presses against the locking rod 302. During the high-speed rotation of the grinding disc for grinding, the spring 5 can generate stable pressure to ensure that the locking rod 302 is always firmly locked in the locking hole 4 and will not loosen due to the high-speed rotation of the grinding disc, thus making the entire grinding disc more stable and reliable during operation.

[0025] The grinding plate 2 has a limiting groove 204, which is connected to the operating hole 203. When the grinding plate 2 needs to be disassembled, the user pushes the locking rod 302 out of the lock hole 4 by pushing the rod 303. However, due to the pushing force of the spring 5, once the user releases his hand, the locking rod 302 will return to the lock hole 4 under the action of the spring 5. At this time, the user only needs to push the rod 303 into the limiting groove 204 to fix the rod 303 in the limiting groove 204, so that the locking rod 302 will not be pushed back into the lock hole 4 by the spring 5.

[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
