Abstract
Description
Technical Field
[0001] This application belongs to the field of grinding plate structures for grinding machines, and specifically relates to a grinding plate structure. Background Technology
[0002] Grinding discs typically have openings to draw in dust and air mixtures, preventing dust from accumulating between the grinding layer of the grinding disc and the workpiece during grinding, thus affecting the surface quality. Existing grinding discs have dust suction passages and air intake passages. Air is drawn in through the air intake passage and then transported through the air duct to the grinding surface between the grinding layer of the grinding disc and the workpiece. As the air passes over the grinding surface, it carries away the heat and dust.
[0003] However, current air intake passages are mainly located on the side of the flexible layer of the grinding disc, or between the flexible layer and the rigid connecting plate. This presents the following problems: During localized pressing grinding, the pressure between the grinding layer of the grinding disc and the workpiece increases, compressing the flexible layer of the grinding disc. This leads to insufficient or inadequate air intake. Furthermore, when applying force to the grinding disc, the grinding heat is more severe, and more grinding dust is produced, consequently affecting the surface quality of the workpiece. Additionally, the current grinding disc air intake diameter is relatively small, resulting in insufficient air intake. Summary of the Invention

Detailed Implementation
[0039] Example
[0040] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0041] The following is in conjunction with the appendix Figure 1-13 The present application provides a detailed description of a grinding plate structure through specific embodiments and application scenarios.
[0042] refer to Figure 1 and Figure 2 The grinding plate structure provided in this application embodiment may include: a receiving base 200, a first connecting plate 300, a second connecting plate 400, a support member 500, and a grinding disc body 600; the second connecting plate 400 is provided with a protrusion 403 that serves as a partition; the receiving base 200, the second connecting plate 400, the first connecting plate 300, the support member 500, and the grinding disc body 600 are arranged sequentially. The distance between the first connecting plate 300 and the second connecting plate 400 is the height of the protrusion 403, and the distance between the first connecting plate 300 and the second connecting plate 400 is preferably between 2mm and 5mm, preferably 3mm, which avoids the grinding disc from being too thick overall, while also meeting the air intake requirements.
[0043] Combination Figure 4 and 5 The first connecting plate 300 has a disc-shaped structure and is provided with an air intake passage 301, a first receiving passage 302, a second receiving passage 303, a positioning passage I 304, a middle passage I 305, an edge 310, a first plane 311, and a second plane 312. The air intake passage 301, the first receiving passage 302, the second receiving passage 303, and the positioning passage I 304 are all evenly distributed circumferentially along the edge 310. The second connecting plate 400 is provided with a protrusion 403, which is preferably an annular protrusion. The annular protrusion mainly serves to limit the distance between the first connecting plate 300 and the second connecting plate 400. The appropriate distance between the first connecting plate 300 and the second connecting plate 400 allows external air to pass through the air intake passage 301 between the first connecting plate 300 and the second connecting plate 400 and enter the slots on the grinding disc body 600. These slots refer to the first slot 611, the second slot 612, and the third slot 618.
[0044] like Figure 5 As shown, the first connecting plate 300 has an edge 310, which is a bevel, and the direction of the bevel is the direction formed by the circumference of the second plane 312 being greater than the circumference of the first plane 311. This facilitates the entry of gas into the intake passage 301.
[0045] Combination Figure 6-8Within the inner ring enclosed by the annular protrusion 403, there are a first connecting passage 402, a first connecting pipe 4021, a second connecting passage 404, a second connecting pipe 4041, a positioning passage II 405, a positioning pipe 4051, an intermediate passage II 406, and an intermediate pipe 4061. When the second connecting plate 400 contacts the first connecting plate 300, the annular protrusion 403 is located between the air intake passage 301 and the first receiving passage 302. The first connecting pipe 4021 cooperates with the first receiving passage 302. The second connecting pipe 4041 cooperates with the positioning passage I 304 to provide circumferential fixation. The positioning tube 4051 cooperates with the second receiving passage 303, and the intermediate tube 4061 cooperates with the intermediate passage I 305; the second connecting plate 400 and the first connecting plate 300 are located between the receiving seat 200 and the support member 500. The receiving seat 200 and the support member 500 are connected by the fixing member 100. The connecting body composed of the second connecting plate 400, the first connecting plate 300, the receiving seat 200 and the support member 500 is bonded to the grinding disc body 600.

The first air inlet 610, the second air inlet 613, and the sixth air inlet 617 are equidistant from the center of the intermediate passage III 620; the third air inlet 614, the fifth air inlet 616, and the seventh air inlet 619 are equidistant from the center of the intermediate passage III 620; the grinding disc body 600 has at least one of the first slot 611, the second slot 612, and the third slot 618; the first slot 611, the second slot 612, and the third slot 618 are arranged alternately for balanced heat dissipation. The first slot 611, the second slot 612, and the third slot 618 are evenly distributed on the grinding disc body 600. External air enters through intake passage 301 into the first slot 611, the second slot 612, and the third slot 618. It then enters the grinding surface between the grinding plate and the workpiece through the first intake port 610, the second intake port 613, the sixth intake port 617, the third intake port 614, the fifth intake port 616, and the seventh intake port 619, blowing away dust and heat from the grinding surface. The air then escapes through the exhaust port.

The first air outlet 650, the second air outlet 651, and the fifth air outlet 654 are connected. The first air outlet 650 and the fourth air outlet 653 are equidistant from the center of the intermediate passage III. The second air outlet 651 and the third air outlet 652 are equidistant from the center of the intermediate passage III. The first air outlet 650 and the fourth air outlet 653 are arranged circumferentially on the grinding disc body 600 at intervals. The first air outlet 650, the second air outlet 651, and the fifth air outlet 654 are connected, and the gas carrying dust and heat finally overflows through the first connecting passage 402 connected to the second air outlet 651. The third air outlet 652 and the fourth air outlet 653 are connected, and the gas carrying dust and heat overflows through the first connecting passage 402 connected to the third air outlet 652. The first connecting passage 402 is circumferentially distributed on the second connecting plate 400, and the number of the first connecting passages 402 is equal to the sum of the second air outlet 651 and the third air outlet 652. This facilitates the layout of the air outlets and better dissipates the heat between the grinding layer of the grinding plate in contact with the workpiece and the grinding surface between the workpiece being ground.
[0048] Combination Figure 9 The support member 500 is provided with edge holes 501, a central passage IV 502, and an undulating edge 503.
