DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0030] The present application aims to provide a hand-held polishing appliance for a polishing machine, which can polish the surface of a sample uniformly and avoid polishing deviation.
[0031] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0032] Reference Figures 1-5 The present embodiment provides a hand-held polishing appliance 100 for a polishing machine, which comprises a disc body 1, a handle 2 and a level.
[0033] The lower surface of the disc body 1 is provided with a first groove, and a limiting member 14 is arranged in the first groove. The first groove is used for accommodating a workpiece to be polished, and the limiting member 14 is used for limiting the upper end of the workpiece. The handle 2 is connected to the disc body 1 and is held by a worker. The level is installed on the disc body 1 or the handle 2 and is used for displaying the level when the disc body 1 is horizontal.
[0034] The working principle of the hand-held polishing appliance 100 for a polishing machine in the present embodiment is as follows:
[0035] The worker holds the handle 2 and presses it down, so that the workpiece in the first groove is pressed towards the polishing member (polishing disc or polishing plate) of the polishing machine 200, and the lower surface of the workpiece is polished flat. During the polishing process, the worker adjusts the angle of the handle 2 according to the levelness displayed by the level, so that the disc body 1 remains horizontal, thereby the lower surface of the workpiece is polished uniformly and polishing deviation is avoided.
[0036] As a possible example, in the embodiment, the disc body 1 comprises a disc 11 and a reinforcing ring 12, the reinforcing ring 12 is sleeved on the outer side of the disc 11. The reinforcing ring 12 is used to strengthen the structural strength of the disc 11, so as to avoid the deformation of the disc 11 under the pressure. For example, the disc 11 is located at the central position of the reinforcing ring 12 in the up-down direction.
[0037] As a possible example, in the embodiment, the side wall of the first groove is the inner wall of a cylinder 15, the cylinder 15 is fixedly connected with the disc 11, and the lower end of the cylinder 15 is lower than the lower end of the reinforcing ring 12. By using the cylinder 15 to provide the first groove, the depth of the first groove can be increased, which is not limited by the thickness of the disc 11, so that the workpiece with greater height can be accommodated. By making the lower end of the cylinder 15 lower than the lower end of the reinforcing ring 12, the reinforcing ring 12 can be avoided to shield the line of sight as much as possible, so as to facilitate the observation of the grinding condition from the side.
[0038] As a possible example, in the embodiment, the handle 2 is vertically arranged, and the lower end of the handle 2 is connected with the disc 11. By vertically arranging the handle 2, it is more convenient for the worker to apply the downward pressure compared with the horizontal or inclined arrangement of the handle 2. In addition, the arm of the worker is located above the disc 1, which can avoid the arm from being injured by contacting the polishing part of the polishing machine 200.
[0039] As a possible example, in the embodiment, the upper end of the handle 2 is provided with a second groove 21, and the level meter is fixed in the second groove 21. The disc 1 will vibrate during the grinding process, and the handle 2 vibrates less than the disc 1 under the holding of the worker. By fixing the level meter at the top end of the handle 2, on the one hand, the height of the level meter is increased, which is convenient for observation, and on the other hand, the influence of vibration on the display state of the level meter is reduced, and the display accuracy of the level meter is improved.
[0040] As a possible example, in the embodiment, the disc 11 is fixed with a nut 13, the lower end of the handle 2 is threadedly connected with the nut 13, and the lower end of the handle 2 is provided with an external thread matched with the nut 13. By adopting the threaded connection, the handle 2 is convenient to disassemble, so as to occupy smaller space during storage.
[0041] As a possible example, in the embodiment, the nut 13 is fixed at the central hole of the disc 11. The number of the first grooves is multiple, and the multiple first grooves are distributed in the circumferential direction with the handle 2 as the center. The downward pressure acts on the center of the disc 11, and is applied to the polishing part of the polishing machine 200 through the workpieces distributed around, so that the workpieces around can share the downward pressure relatively uniformly. At the same time, by arranging multiple first grooves, multiple workpieces can be polished at the same time, and the polishing efficiency is improved.
[0042] As a possible example, in the embodiment, the plurality of first grooves are evenly distributed along the circumferential direction of the handle 2. For example, the number of the first grooves is four.
[0043] As a possible example, in the embodiment, the upper end of the nut 13 is higher than the upper end of the reinforcing ring 12, so that there is a larger space between the polishing member of the grinding and polishing machine 200 and the nut 13, thereby enabling the handle 2 to extend downwardly from the nut 13 by a certain distance.
[0044] As a possible example, in the embodiment, the first grooves are circular grooves, and the limiting members 14 are blocking rods arranged along the diameters of the first grooves. By using the blocking rods as the limiting members 14, a certain gap can be left to facilitate the real-time observation of the grinding condition of the workpiece in the first grooves by the workers. In each first groove, the number of the blocking rods can be one or more. However, the actual implementation is not limited thereto. For example, the limiting members 14 can also be horizontal plates.
[0045] The principle and implementation mode of the present application are described by using specific examples in the present application, and the above examples are only used to help understand the method and core idea of the present application. Meanwhile, for the general skilled in the art, the specific implementation mode and application range will be changed according to the idea of the present application. In conclusion, the content of the present application should not be understood as a limitation of the present application.
