Technical Field

[0001] The utility model relates to the technical field of brazed diamond grinding wheel production, in particular to a diamond abrasive grain orderly arrangement device for brazed diamond grinding discs. Background Art

[0002] Brazed diamond grinding wheel refers to a tool that fixes diamond particles on the surface of the grinding wheel through a brazing process and is used for grinding and processing various materials. Diamond grinding wheels are mostly processed by using adhesives to arrange diamond abrasive particles on the grinding wheel, and then brazing is performed.

[0003] The Chinese patent "A Diamond Abrasive Arrangement Structure" authorization announcement number "CN219725847U" uses an air pump, an arrangement plate and arrangement holes to arrange diamond abrasive grains on a cold-pressed thin blank workpiece, thereby improving the efficiency of arranging diamond abrasive grains on the workpiece.

[0004] Since the air pump is located in the middle of the two arrangement plates, the generated airflow may be unevenly distributed in the diamond barrel, which may easily cause the diamond abrasives to be unevenly adsorbed on the arrangement plates, thereby affecting the uniformity of the diamond abrasives arranged on the workpiece.

[0005] Therefore, a diamond abrasive grain orderly arrangement device for brazed diamond grinding disc is proposed to solve the above problems. Utility Model Content

[0023] 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.

[0024] When implementing: Figure 1-4As shown, a diamond abrasive grain orderly arrangement device for brazing diamond grinding discs comprises: a work frame 1, both sides of the inner wall of the work frame 1 are rotatably connected with pulleys 2, the surface of the pulley 2 is transmission-connected with a belt 3, the surface of the belt 3 is provided with electromagnets 4 distributed in equal rows, and the surface of the work frame 1 is provided with a driving mechanism 5; wherein the driving mechanism 5 comprises a material box 51 fixedly connected to the inner wall of the work frame 1, the inner wall of the material box 51 is provided with an auger conveying cylinder 52, the inner side of the work frame 1 is provided with an arrangement frame 53, and the arrangement frame 54 is arranged on the inner side of the work frame 1. A driven block 54 is hinged at the bottom of the cloth frame 53, and an active block 55 is hinged at the bottom of the driven block 54. A driving assembly 56 is arranged on the surface of the working frame 1, and the driving assembly 56 includes a first motor 561 fixedly connected to the surface of the working frame 1, and the output shaft of the first motor 561 is fixedly connected to the bottom of the active block 55. A scraper 562 is arranged on the top of the arrangement frame 53, and connecting frames 563 are fixedly connected to both sides of the top of the support plate 564, and the bottom of the connecting frame 563 is fixedly connected to the top of the scraper 562.

[0025] The auger conveying cylinder 52 includes an auger, a feed cylinder and a second motor. The feed cylinder is fixed to the inner wall of the material box 51, the auger is rotatably connected to the inner top wall of the feed cylinder, the surface of the second motor is fixedly connected to the surface of the feed cylinder, the output shaft of the second motor is fixedly connected to the top of the auger, and the discharge end of the feed cylinder is inclined downward.

[0026] When diamond abrasive grains need to be arranged on the surface of the grinding wheel, the auger conveying cylinder 52 is started. After the auger conveying cylinder 52 transports a certain amount of diamond abrasive grains in the material box 51 to the arrangement frame 53, the auger conveying cylinder 52 is closed, and the first motor 561 is started. The output shaft of the first motor 561 rotates to drive the active block 55 to rotate, and the active block 55 rotates to pull the driven block 54 to move back and forth. The reciprocating movement of the driven block 54 drives the arrangement frame 53 to move back and forth, so that the diamond abrasive grains shake back and forth in the arrangement frame 53, and the scraper 562 scrapes the diamond abrasive grains flat, the electromagnet 4 adsorbs the grinding wheel and applies pressure-sensitive adhesive to the grinding wheel, and the belt 3 drives the corresponding grinding wheel to move to the arrangement frame 53 for uniform and orderly arrangement. After arrangement, the grinding wheel is transported to the next link for brazing operation.

[0027] like Figure 2 As shown, a support plate 564 is fixedly connected to the inner side of the work frame 1, and discharge holes 566 distributed in equal rows are opened on the top of the support plate 564. A through hole 568 is opened on the top of the support plate 564. The surface of the arrangement frame 53 is slidably connected to the inner wall of the through hole 568. The shape of the discharge hole 566 is an isosceles trapezoid. A material guide frame 567 is fixedly connected to the bottom of the support plate 564, and the front end of the material guide frame 567 is connected to the inner wall of the material box 51.

[0028] The diamond abrasive grains fall out of the arrangement frame 53 during the reciprocating shaking, and fall into the material guide frame 567 through the discharge hole 566 and the through hole 568. Since the material guide frame 567 is inclined, the diamond abrasive grains in the material guide frame 567 roll into the material box 51.

[0029] like Figure 3 As shown, the bottom of the arrangement frame 53 is rotatably connected to a roller 569, and the surface of the roller 569 is rollingly connected to the top of the support plate 564. The reciprocating movement of the arrangement frame 53 drives the roller 569 to roll on the support plate 564, and the roller 569 ensures the smooth movement of the arrangement frame 53 on the support plate 564.

[0030] like Figure 3 As shown, the inner wall of the through hole 568 is fixedly connected to the limiting rod 565, and the inner wall of the arrangement frame 53 is slidably connected to the surface of the limiting rod 565. The limiting rod 565 is used to limit the moving arrangement frame 53.

[0031] When the utility model is in use, the auger conveying cylinder 52 is started, and after a certain amount of diamond abrasive grains in the material box 51 are conveyed to the arrangement frame 53, the auger conveying cylinder 52 is closed, and the first motor 561 is started. The output shaft of the first motor 561 rotates through the active block 55 and the driven block 54 to drive the arrangement frame 53 to move back and forth, so that the diamond abrasive grains reciprocate and shake in the arrangement frame 53, and the scraper 562 flattens the diamond abrasive grains, the electromagnet 4 absorbs the grinding wheel and applies pressure-sensitive adhesive to the grinding wheel, and the belt 3 drives the corresponding grinding wheel to move to the arrangement frame 53 for uniform and orderly arrangement. After arrangement, the grinding wheel is conveyed to the next link for brazing operation.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
