[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0030] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0031] See also Figure 1-Figure 3 This embodiment provides a machining protection device, which includes a chuck 100 and a protection component; the chuck 100 is used to clamp a workpiece, and the protection component is detachably connected to the chuck 100; the protection component includes a baffle 200, and the baffle 200 can shield the non-machined surface of the workpiece.

[0032] Before machining the workpiece, a suitable protective component can be selected according to the shape, size and other characteristics of the workpiece, the selected protective component can be installed on the chuck 100, and the chuck 100 can be used to clamp the workpiece. At this time, the baffle 200 in the protective component can cover the non-machined surface of the workpiece. In this way, when the workpiece is machined, the debris falling from the machined surface is thrown out and splashed toward the non-machined surface of the workpiece, which will be blocked by the baffle 200, thereby reducing the amount of debris splashing onto the non-machined surface of the workpiece. Therefore, there is no need to reduce the number of revolutions and feed rate of the lathe, and the problem of the non-machined surface of the workpiece being damaged by the falling debris can be alleviated, which is beneficial to improving the machining efficiency.

[0033] It should be noted that the machining protection device provided in this embodiment can realize the replacement of the type of protection components by connecting the protection components to the chuck 100 in a detachable manner, and thus can adapt to more types of workpieces and has strong versatility.

[0034] When the workpiece is a wheel hub, its non-machined surface is the surface in the hollow window, and the baffle 200 can extend into the hollow window and adapt to the non-machined surface in the hollow window.

[0035] When machining the wheel hub, the lathe speed can be increased from 900 to 1000 rpm to 1200 to 1400 rpm; the feed can be increased from 0.25 to 0.45.

[0036] The above-mentioned protective component may also include a mounting disk 300, and the baffle 200 is installed on the mounting disk 300, and the mounting disk 300 is installed on the chuck 100 in a detachable connection manner. In this way, the mounting disk 300 can be used to determine the relative position and installation angle of each baffle 200. During assembly, it is only necessary to fix the mounting disk 300 of the selected protective component to the chuck 100, and there is no need to install each baffle 200 separately, which is beneficial to improving assembly efficiency. In addition, each group of protective components can select mounting disks 300 of the same shape, and the mounting disks 300 in different protective components are connected to the chuck 100 using the same connection structure, which is beneficial to simplify the connection structure between the chuck 100 and the protective component.

[0037] Specifically, the mounting plate 300 and the chuck 100 can be connected via a threaded connector 400 , which can both meet the requirement of detachability and ensure the connection reliability between the mounting plate 300 and the chuck 100 .

[0038] Preferably, the threaded connectors 400 may be provided in multiple groups, and the multiple groups of threaded connectors 400 may be evenly arranged around the center of the mounting plate 300, so as to obtain a better fixing effect.

[0039] Specifically, a waist-shaped hole 310 can be opened on the mounting plate 300, and a threaded hole can be opened on the chuck 100. During assembly, the threaded connector 400 can be passed through the waist-shaped hole 310 on the mounting plate 300 and then screwed into the threaded hole on the chuck 100. In this way, the threaded connector 400 can achieve the relative positioning effect of the mounting plate 300 and the chuck 100.

[0042] Furthermore, the first limiting portion 121 can be matched with the first avoiding groove 320 so that the first limiting portion 121 and the first avoiding groove 320 can limit each other to form a locking effect; the second limiting portion 131 can be matched with the second avoiding groove 330 so that the second limiting portion 131 and the second avoiding groove 330 can limit each other to form a locking effect, thereby preventing the mounting disk 300 from rotating circumferentially relative to the chuck 100, which is beneficial to improving the connection reliability between the mounting disk 300 and the chuck 100, so that the chuck 100 can drive the mounting disk 300 to rotate synchronously.

[0043] The threaded connector 400 can be connected to a portion of the mounting plate 300 close to the first avoidance groove 320, or can be connected to a portion of the mounting plate 300 close to the second avoidance groove 330. Of course, the threaded connector 400 can also be installed at a portion of the mounting plate 300 close to the first avoidance groove 320 and a portion of the mounting plate 300 close to the second avoidance groove 330, which can reduce the difficulty of locking and disassembling the threaded connector 400.

[0044] A first fixing portion flush with the top surface of the main body 110 can be provided on the above-mentioned claw 120, and the mounting disk 300 and the first fixing portion of the claw 120 are connected through the above-mentioned threaded connector 400. In this way, the threaded connector 400 can realize a fixed connection between the mounting disk 300 and the chuck 100, and the locking and disassembly operations of the threaded connector 400 are facilitated.

[0045] A second fixing portion flush with the top surface of the main body 110 can be provided on the above-mentioned limit block 130, and the mounting plate 300 and the second fixing portion of the limit block 130 are connected via the above-mentioned threaded connector 400. In this way, the threaded connector 400 can realize a fixed connection between the mounting plate 300 and the chuck 100, and the locking and disassembly operations of the threaded connector 400 are facilitated.

[0046] Preferably, the baffle 200 and the mounting plate 300 may be fixed by welding or riveting, which may achieve a good fixing effect.

[0047] The shape of the mounting plate is preferably circular. Of course, the mounting plate can also be set to other shapes as needed.
