[0022] Figure 1 This is a schematic structural diagram of a phosphor bronze ball grinding device according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, and reference Figures 2 to 3 The embodiment of the utility model provides a phosphor bronze ball grinding device, which includes a mounting frame 1, a discharging mechanism 2, a first grinding belt 6, a second grinding belt 5, a grinding plate 4, a baffle 10, a debris box 9, a discharge pipe 8 and a storage box 7.

[0023] The first and second grinding belts 6, 5, and 4 are mounted on a mounting frame 1, defining a grinding gap 12 for grinding the workpiece. A discharge mechanism 2 is fixedly mounted on the mounting frame 1, located diagonally above the grinding gap 12. A discharge chute 3 is located between the discharge mechanism 2 and the grinding plate 4. The chute 3 is semi-cylindrical and angled downward.

[0024] The mounting frame 1 is provided with a vertical through-hole 11, which is cylindrical and located below the grinding gap 12. One end of the discharge pipe 8 is connected to the bottom end of the through-hole 11, and the other end is connected to the storage box 7. The storage box 7 is provided with a water inlet 702 and a water outlet 701, and the storage box 7 is filled with cooling water. The baffle 10 is slidably mounted on the mounting frame 1 and is located in the middle of the grinding gap 12 and the through-hole 11. The debris box 9 is arranged directly below the discharge pipe 8. There are multiple small holes on the baffle 10 and the discharge pipe 8, and the size of the small holes is smaller than the size of the workpiece to be ground, so that the debris generated by grinding can fall into the debris box 9 through the small holes. This grinding device has the function of collecting debris and immediately cooling after grinding is completed. It is comprehensive in function and highly practical.

[0025] Specifically, the grinding plate 4 is an arc-shaped plate and has grinding lines on the side close to the grinding gap 12 .

[0026] Specifically, the discharge pipe 8 is "L"-shaped, and the horizontal section is inclined downward, so that the polished phosphor bronze balls can slide into the storage box 7 under the action of gravity.

[0027] Furthermore, a small hole on the discharge pipe 8 for allowing the debris generated by grinding to fall into the debris box 9 is provided at the turning point of the discharge pipe 8 and is located directly below the grinding gap 12 .

[0028] Specifically, the baffle 10 is used to prevent the workpiece to be polished from falling into the through opening 11 under the action of gravity.

[0029] In some embodiments of the present invention, Figure 2As shown, the discharging mechanism 2 includes a hopper 201, a servo motor 208, a plurality of blades 203, a hopper bottom plate 207, a connecting shaft 206 and a partition 204. The hopper 201 is fixedly mounted on the mounting frame 1, and the servo motor 208, the partition 204, the hopper bottom plate 207, the plurality of blades 203 and the connecting shaft 206 are all arranged in the hopper 201. The hopper bottom plate 207 is fixedly mounted on the bottom end of the hopper 201. The connecting shaft 206 is mounted on the central axis of the hopper bottom plate 207 and is arranged vertically. The plurality of blades 203 are evenly distributed along the circumference of the inner wall of the hopper 201. One end of the blade 203 is fixedly connected to the connecting shaft 206, the other end is in contact with the inner wall of the hopper 201, and the bottom end is in contact with the hopper bottom plate 207. The blade 203 is placed vertically and rotates horizontally with the connecting shaft 206 as the axis. The servo motor 208 is mounted on the connecting shaft 206 and is located below the hopper bottom plate 207, and is used to control the rotation of the connecting shaft 206. A discharge gap 202 is formed between every two blade plates 203, and a specified number of parts to be polished are contained in the discharge gap 202. The partition 204 is fixedly mounted on the inner wall of the hopper 201 so that when a discharge gap 202 rotates to the bottom of the partition 204, the partition 204 and the discharge gap 202 define a discharge cavity. A discharge port 205 is provided on the inner wall of the hopper 201 and is connected to the discharge cavity. The discharge port 205 is tilted downward to facilitate the outflow of the parts to be polished. The discharge mechanism 2 can realize timed and quantitative discharge, and has a high degree of automation.

[0030] Specifically, the hopper 201 is in a circular cylindrical shape.

[0031] Specifically, a discharge button is provided on the hopper 201 , and the discharge button can realize manual discharge by controlling the servo motor 208 .

[0032] Specifically, the designated number refers to the maximum number of workpieces that can be simultaneously ground by the grinding gap 12 at one time.

[0033] Furthermore, the blade plates 203 are detachable and installable, and the discharge gap 202 is increased or decreased by controlling the distance between the two blade plates 203 , thereby adjusting the number of parts to be polished in the discharge gap 202 .

[0034] In some embodiments of the present invention, Figure 2-3 As shown, the first grinding belt 6 includes two first rotating shafts 602, two first rollers 601, a first grinding belt 603, a driving motor 605, a first support plate 604, and a first bevel gear 606. The second grinding belt 5 includes two second rotating shafts 501, two second rollers 502, a second bevel gear 506, a second support plate 505, and a second grinding belt 503.

[0035] The two first rotating shafts 602 are vertically parallel to each other. The upper first rotating shaft 602 is fixedly mounted on the mounting frame 1, and the lower first rotating shaft 602 passes through the mounting frame 1 and is connected to the rear drive motor 605. The drive motor 605 is used to drive the lower first rotating shaft 602 to rotate. The lower first rotating shaft 602 is rotationally connected to the mounting frame 1. One first rotating shaft 602 is correspondingly mounted on the central axis of one first roller 601. The two first rollers 601 are connected by a first sanding belt 603. The two first rollers 601 are rotatably mounted at both ends of a first support plate 604. The first support plate 604 is used to support the first sanding belt 603 to sand the workpiece to be sanded. The rotation of the lower first roller 601 drives the upper first roller 601 to rotate, and at the same time drives the first sanding belt 603 to rotate.

[0036] The two second rotating shafts 501 are vertically parallel to each other. Each second rotating shaft 501 is mounted on the central axis of a corresponding second roller 502. The two second rollers 502 are rotatably mounted at both ends of a second support plate 505. The two second rollers 502 are connected by a second abrasive belt 503. The second support plate 505 is fixed to the mounting frame 1 via a fixing member 504.

[0037] The first bevel gear 606 is mounted on the lower first rotating shaft 602, and the second bevel gear 506 is mounted on the lower second rotating shaft 501. The first bevel gear 606 and the second bevel gear 506 mesh with each other, so that rotation of the lower first rotating shaft 602 drives rotation of the lower second rotating shaft 501. The first and second bevel gears 606 and 506 are linked to each other. Operation of the drive motor 605 allows the first and second grinding belts 6 and 5 to run simultaneously, allowing for simultaneous grinding operations. This method saves energy.

[0038] Specifically, the first grinding belt 603 and the second grinding belt 503 rotate in opposite directions.

[0039] Working Principle: When performing the phosphor bronze ball grinding operation, first press the discharge button (the servo motor 208 can also be used to set the timed discharge) to allow multiple phosphor bronze balls to flow out of the discharge port 205 through the discharge chute 3 and fall into the grinding gap 12. Then, turn on the drive motor 605 to perform the grinding operation. Furthermore, after the grinding operation is completed, the baffle 10 below the grinding gap 12 is pulled out, allowing the multiple polished phosphor bronze balls to fall into the storage box 7 through the through-port 11 and the discharge pipe 8. Finally, the polished phosphor bronze balls are cooled and stored in the storage box 7. The above workflow is the process for grinding a batch of phosphor bronze balls. Repeating this process can greatly improve the efficiency of phosphor bronze ball grinding.
