[0024] like Figures 1 to 3As shown, a circular arc grinding wheel grinding tool 10 of the present application includes: a circular arc grinding wheel 11 and a grinder 12, and the grinder 12 can grind the circular arc grinding wheel 11 in time. A flange 13 is installed in the center hole formed in the center of the circular arc grinding wheel 11, and the flange 13 is provided with a central axis hole 131. A tool handle 15 is installed in the central axis hole 131, and the circular arc grinding wheel 11 can be rotatably installed on the grinder 12 through the tool handle 15 for circumferential grinding. Such an installation structure can install and grind the circular arc grinding wheel 11 at any time, which is convenient to use and solves the problem that the circular arc grinding wheel 11 needs to be repaired after the arc is worn and delays production. Through the tool handle 15, not only can the circular arc grinding wheel 11 be installed on the grinder 12 for grinding, but also the circular arc grinding wheel 11 can be installed on the machine for processing curved surface products to grind the curved surface products. In this way, the switching structure of the working state and the maintenance state of the circular arc grinding wheel 11 is simpler and more efficient.
[0025] Specifically, the grinder 12 includes: a mounting seat 121, two mounting rods 122 and two grinding plates 123. During installation, the two mounting rods 122 are respectively mounted on the upper and lower ends of the side of the mounting seat 121. A driving motor 16 is installed in the mounting seat 121, and the handle 15 is rotatably mounted in the middle of the side of the mounting seat 121 and one end is connected to the motor shaft of the driving motor 16. The two grinding plates 123 are respectively slidably mounted on the two mounting rods 122, so that when the driving motor 16 is turned on, the handle 15 can be driven to rotate, thereby driving the circular arc grinding wheel 11 to rotate, and the circular arc grinding wheel 11 generates friction grinding with the grinding plates 123 arranged above and below when rotating. Adjusting cylinders 18 are respectively installed on the two mounting rods 122 for pushing the corresponding grinding plates 123 to adjust the grinding diameter between the two grinding plates 123. In this way, the grinding diameter between the two grinding plates 123 can be adjusted according to different types of arc grinding wheels 11, thereby enabling grinding of different types of arc grinding wheels 11 and improving the grinding versatility of the arc grinding wheel grinding tool 10.
[0026] A battery is also installed in the mounting base 121 to provide power to the driving motor 16 and the adjusting cylinder 18, making it more portable and able to be powered by the battery when there is no socket power supply.
[0027] The mounting base 121 can also be installed with a power cord for plugging into a power socket, and the power cord is electrically connected to the driving motor 16 and the adjusting cylinder 18 to provide electrical energy.
[0028] Therefore, the arc grinding wheel grinding tool 10 is easy to operate and carry, which improves production efficiency, reduces the inventory of arc grinding wheels 11, and reduces production costs. The arc grinding wheel grinding tool 10 can also grind arc grinding wheels 11 of different models, has high versatility, and has higher grinding accuracy.
[0029] As a specific implementation, a connecting block 124 is fixed to the rear side of the grinding sheet 123, and the connecting block 124 can be detachably mounted on the lever of the regulating cylinder 18, so that the grinding sheet 123 can be easily replaced and used. Specifically, a threaded hole is formed at the end of the lever, and the connecting block 124 is installed at the end of the lever by passing a bolt through the through hole formed by the connecting block 124 and screwing into the threaded hole. Such a threaded connection structure is simple and stable, and it is very convenient to disassemble and replace the grinding sheet 123. Although the through hole and the threaded hole are not clearly shown in the drawings, the staff in this field can clearly know the bolt-fixed connection method, and through the above structural description, the installation and use of the tooling of this solution can be realized.
[0030] The grinding sheet 123 is formed with a limiting portion 1231 for limiting the axial position of the arc grinding wheel 11. When the arc grinding wheel 11 is inserted into the mounting seat through the tool handle 15, the upper and lower grinding sheets 123 are driven by the adjusting cylinder 18 to press the arc grinding wheel 11. At this time, the limiting portion 1231 is stuck on both sides of the arc grinding wheel 11, thereby ensuring the grinding accuracy of the arc grinding wheel 11.
[0031] Furthermore, the mounting rod 122 is formed with a slide groove 1221, the connecting block 124 is slidably arranged in the slide groove 1221, and the grinding sheet 123 is fixed to the end of the connecting block 124 located outside the slide groove 1221. Such a sliding connection structure, through the constraint of the slide groove 1221, can effectively ensure the structural accuracy of the connection structure between the grinding sheet 123, the connecting block 124 and the adjusting cylinder 18 while realizing sliding adjustment.
[0032] As a specific implementation, a first control switch 20 and a second control switch 21 are provided on the other side of the mounting base 121 for controlling the drive motor 16 and the regulating cylinder 18, respectively. During installation, the first control switch 20 is electrically connected to the drive motor 16, and the second control switch 21 is electrically connected to the regulating cylinder 18. The electrical connection structure of the control switch here is an existing switch connection structure, and its internal connection circuit is an existing circuit. Although the circuit is not disclosed in this solution, the staff in this field can clearly know the working principle and operation mode of the control switch, and the purchased control switch can be connected to the drive motor 16 and the regulating cylinder 18 by lines.
[0033] As a specific implementation, a handle 22 is provided on the other side of the mounting seat 121 for the user to carry the mounting seat 121. The projection area of the mounting seat 121 is larger than the projection area of the arc grinding wheel 11, so that when the user carries the handle 22 to grind the arc grinding wheel 11, the mounting seat 121 itself can be used as a shield to block the debris generated during grinding, thereby protecting the user.
[0034] As a specific implementation, a gasket 14 is provided between the screw and the side wall of the mounting shaft hole on the other side of the flange 13 to strengthen the locking force. The flange 13 includes an upper flange 132 and a lower flange 133, which are respectively mounted on both sides of the arc grinding wheel 11 and fixed as a whole by locking screws to lock the arc grinding wheel 11. Such an installation structure is convenient for disassembly and installation of the arc grinding wheel 11 and convenient for replacement.
[0035] The battery placed there is installed in the mounting seat 121, which is not shown. However, the staff in this field can clearly know that the battery and the drive motor 16 and the regulating cylinder 18 can be powered by connecting the lines. A rotating mounting hole 1211 is formed on the side of the mounting seat 121, and a rotating bearing 23 is provided in the rotating mounting hole 1211. The inner wall of the rotating bearing 23 is fixed with a sleeve 24, and the sleeve 24 is fixedly connected to the motor shaft 161 of the drive motor 16. The handle 15 is inserted into the sleeve 24 during installation and connected with the inner wall of the sleeve 24 by spline 25, wherein the sleeve 24 and the motor shaft 161 of the drive motor 16 are also connected by spline 25. Such a transmission structure is simple and stable, and is a shaft transmission structure connected by spline 25 known to the staff in this field, which is convenient for the staff in this field to install and maintain.
[0036] The tool handle 15 in the above scheme is also threadedly installed with a connector 19, through which the arc grinding wheel 11 can be installed on the grinding machine to grind curved products. The structure is easy to install and the installation position of the arc grinding wheel 11 can be easily changed.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
