[0003] However, in the prior art, the polishing disc of the existing polishing machine will be worn after long-term use. In order to ensure the polishing effect of the object in the future, the worn polishing disc is generally replaced, but the polishing disc is generally installed and fixed by bolts, which makes the disassembly and installation process more cumbersome and inconvenient for the staff to install and replace the polishing disc. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: the polishing disc is generally installed and fixed by bolts, which makes the disassembly and installation process more complicated and inconvenient for workers to install and replace the polishing disc.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mechanical processing polishing device, including a working frame, a motor is fixedly installed on the top of the working frame, and the output end of the motor is fixedly connected to a rotating shaft, a through groove is opened on the surface of the rotating shaft, one end of the rotating shaft is inserted and connected with a docking shaft, the docking shaft is rotatably connected with a rotating part near its one end, and a polishing disk is penetrated and connected on the surface of the docking shaft, the surfaces of the rotating shaft and the docking shaft are fixedly connected with clamping fixed disks, and a movable limiter is threadedly connected on the outer surface of the rotating shaft.

[0006] As a preferred embodiment, there are multiple rotating members on the docking shaft, and the number of the rotating members is consistent with the number of the through grooves.

[0007] As a preferred implementation manner, a through hole is formed on the surface of the rotating member close to one end thereof.

[0008] As a preferred implementation, a control handle is fixedly connected to the outer surface of the movable limiting member.

[0009] As a preferred embodiment, a storage box is fixedly connected to one side of the work frame.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] According to the utility model, when the polishing disc needs to be replaced, the movable limit part is rotated and moved backward to release the activity restriction of the rotating part, and the rotating part is rotated ninety degrees and retracted into the docking shaft, so that the docking shaft together with the polishing disc can be removed from the rotating shaft, and then the above steps can be reversed to complete the installation operation of the polishing disc. The utility model is simple and quick, and it is convenient for the staff to install and replace the polishing disc. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a mechanical processing and polishing device, including a workbench 1, a motor 2 is fixedly installed on the top of the workbench 1, and a rotating shaft 3 is fixedly connected to the output end of the motor 2. The motor 2 is used as a power source to conveniently control the rotating shaft 3 to rotate. A through groove is opened on the surface of the rotating shaft 3, and a docking shaft 4 is inserted and connected at one end of the rotating shaft 3. A rotating member 5 is rotatably connected near one end of the docking shaft 4. Through the setting of the through groove, the rotating member 5 on the docking shaft 4 in the rotating shaft 3 can be rotated and unfolded, so as to facilitate the rotating shaft 3 drives the docking shaft 4 to rotate, and a polishing disc 7 is connected through the surface of the docking shaft 4, and the rotating polishing disc 7 plays a role of polishing and grinding. The surfaces of the rotating shaft 3 and the docking shaft 4 are fixedly connected with clamping and fixing discs, and the polishing disc 7 is squeezed and fixed by the clamping and fixing disc, so that the polishing disc 7 is conveniently driven to rotate by the rotating shaft 3 and the docking shaft 4. A movable limiting member 8 is threadedly connected on the outer surface of the rotating shaft 3. By allowing the movable limiting member 8 to rotate and move on the rotating shaft 3, the vertical rotating member 5 is movably limited, thereby improving the stability of the docking shaft 4 installed on the rotating shaft 3.

[0020] Example 2

[0021] like Figure 1-3 As shown, there are multiple rotating parts 5 on the docking shaft 4, and the number of rotating parts 5 is consistent with the number of through grooves. By providing multiple rotating parts 5, the stability of the installation of the docking shaft 4 on the rotating shaft 3 can be effectively ensured. A through hole 6 is opened on the surface of the rotating part 5 close to one end thereof. Through the setting of the through hole 6, when the docking shaft 4 is installed into the rotating shaft 3, it is convenient to control the rotating part 5 to perform rotational movement. A control handle 9 is fixedly connected to the outer surface of the movable limit part 8. The setting of the control handle 9 provides convenience for manually controlling the rotation of the movable limit part 8. A storage box 10 is fixedly connected to one side of the workbench 1. The storage box 10 is used to store multiple polishing discs 7 for replacement, so as to facilitate the replacement operation at any time later.

[0022] Working principle:

[0023] like Figure 1-3 As shown, when the utility model is in use, the user first takes out a new polishing disc 7 from the storage box 10, then inserts the docking shaft 4 into the new polishing disc 7, and inserts one end of the docking shaft 4 into the interior of the rotating shaft 3, so that the clamping and fixing disc clamps and fixes the polishing disc 7, and then uses a finger to press the through hole 6 to make the rotating member 5 rotate, so that the rotating member 5 flips out of the through groove of the rotating shaft 3, and then holds the control handle 9 to control the rotation of the movable limit member 8, so that the movable limit member 8 rotates forward on the rotating shaft 3, and the rotating member 5 is movably limited, so that the replacement operation of the polishing disc 7 can be completed.
