Description

Technical Field

[0001] The utility model relates to the technical field of metal part surface processing, and particularly relates to a surface treatment and processing device for a mobile phone middle plate. Background Technique

[0002] Metal parts refer to the general name of various specifications and shapes of metal blocks, metal rods, metal pipes, etc. made of metal materials. Surface treatment of metal parts is an important link to improve the quality of parts. Its surface treatment process includes polishing, spraying, coating, etc. When dealing with the burrs generated on the surface of metal parts during the production process, it is necessary to polish the metal parts to reduce the surface roughness of the workpiece.

[0003] After retrieval, the Chinese patent "A surface processing, grinding and polishing mechanism for metal parts" with the authorization announcement number "CN219444755U" moves the position of the mobile nozzle through the set auxiliary component to align the nozzle with the grinding area. The water mist can prevent dust from flying during grinding, and at the same time prevent the metal from overheating due to friction. Most of the dust and water together fall into the interior of the dirt collection box through the metal mesh for collection, preventing dust from flying during grinding.

[0004] Although the above application can handle the dust generated during grinding, the metal dust and metal chips generated during the grinding of metal parts will fly in different directions. During the grinding process of the metal parts, the nozzle can only spray water in the same direction, resulting in poor protection effect.

[0005] Therefore, a surface treatment and processing device for a mobile phone middle plate is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a surface treatment and processing device for metal parts to solve the above problems, improving the problem that the metal dust and metal chips generated during the grinding of metal parts will fly in different directions, and during the grinding process of the metal parts, the nozzle can only spray water in the same direction, resulting in poor protection effect.

[0007] The utility model realizes the above purpose through the following technical solutions. A surface treatment and processing device for a mobile phone middle plate includes: an operating table, a filter plate is embedded in the inner wall of the operating table, a water tank is fixedly connected to the bottom end of the operating table, a motor is fixedly connected to the top end of the operating table, a grinding disc is fixedly connected to the output shaft of the motor, and a protection mechanism is arranged at the top end of the operating table; wherein, the protection mechanism includes a protection frame fixedly connected to the top end of the operating table, the grinding disc is arranged inside the protection frame, an annular pipe is rotatably connected to the inner wall of the protection frame, a plurality of nozzles are communicated with the surface of the annular pipe, a water pump is installed on one side of the water tank, a connecting pipe is communicated between the annular pipe and the water outlet of the water pump, and through holes are opened at the lower end of the surface of the protection frame.

[0008] Preferably, the protection mechanism further includes a sliding plate connected to one end of the protection frame. A rack is fixedly connected to one side of the sliding plate. A spring is fixedly connected between the surface of the sliding plate and the inner wall of the protection frame. A gear is rotatably connected to the surface of the motor output shaft. The gear is meshed with the rack. A trigger plate is fixedly connected to the other side of the rack. A cam is fixedly connected to the surface of the motor output shaft. The surface of the cam is in contact with one side of the trigger plate. One end of the gear is fixedly connected to a connecting rod. The other end of the connecting rod penetrates to the inside of the protection frame and is fixedly connected to the surface of the annular pipe. Driven by the cam and the spring, the rack reciprocates horizontally, which is beneficial to drive the annular pipe and multiple nozzles to rotate reciprocally to spray the aqueous solution to fuse with the dust and debris generated during grinding.

[0009] Preferably, a mounting rod is fixedly connected to the surface of the motor output shaft. The other end of the mounting rod is fixedly connected to a scraper. The surface of the scraper is in contact with the inner wall of the protection frame. This is beneficial to scrape the dust and debris adhering to the inner wall of the protection frame by the scraper, preventing the debris and dust from remaining in the protection frame and better collecting the dust and debris.

[0010] Preferably, the through hole is arranged above the filter plate. This is beneficial to make the debris generated during grinding and the dust mixed with the aqueous solution fully fall on the filter plate.

[0011] Preferably, the connecting pipe is a flexible pipe and is a plastic component. When the annular pipe rotates reciprocally, the stability of the connecting pipe in use is ensured.

[0012] Preferably, the multiple nozzles are annularly distributed and the nozzles are inclined. This is beneficial to spray the aqueous solution in a better grinding direction.

[0013] Preferably, the vertical section of the scraper is an isosceles triangle. This reduces the friction between the scraper and the inner wall of the protection frame during rotational cleaning, and at the same time, under the action of the inclined surface of the scraper, it is beneficial to make the scraper better scrape the dust and debris adhering to the inner wall of the protection frame.

[0014] The beneficial effects of the present utility model are:

[0015] 1.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-5 shown, a surface treatment and processing device for a mobile phone middle plate includes: an operation table 1, a filter plate 2 is embedded in the inner wall of the operation table 1, a water tank 3 is fixedly connected to the bottom end of the operation table 1, a motor 4 is fixedly connected to the top end of the operation table 1, a grinding disc 5 is fixedly connected to the output shaft of the motor 4, and a protection mechanism 6 is arranged at the top end of the operation table 1; among them, the protection mechanism 6 includes a protection frame 61 fixedly connected to the top end of the operation table 1, the grinding disc 5 is arranged inside the protection frame 61, an annular pipe 62 is rotatably connected to the inner wall of the protection frame 61, a plurality of spray heads 63 are communicated with the surface of the annular pipe 62, a water pump 64 is installed on one side of the water tank 3, a connecting pipe 65 is communicated between the annular pipe 62 and the water outlet of the water pump 64, and a through hole 66 is opened at the lower end of the surface of the protection frame 61.

[0025] The output shaft of the motor 4 is rotatably connected to the inner wall of the protection frame 61, the water tank 3 is filled with an aqueous solution. When grinding a metal part, the worker holds the metal part by hand and makes the metal part enter the protection frame 61 to contact the grinding disc 5. At this time, the worker simultaneously starts the motor 4 and the water pump 64 through the controller. When the motor 4 is started, the output shaft of the motor 4 drives the grinding disc 5 to rotate to grind the metal part. During grinding, the protection frame 61 blocks the generated debris, and the larger debris falls through the through hole 66 under the action of its own gravity. At the same time, when the water pump 64 is started, the aqueous solution in the water tank 3 is introduced into the connecting pipe 65, and after the aqueous solution enters the annular pipe 62, it is sprayed out from the plurality of spray heads 63 to contact the dust and debris generated during grinding.

[0026] As Figure 2 、 Figure 3 and Figure 4 shown, the protection mechanism 6 further includes a sliding plate 67 slidably connected to one end of the protection frame 61, a rack 69 is fixedly connected to one side of the sliding plate 67, a spring 68 is fixedly connected between the surface of the sliding plate 67 and the inner wall of the protection frame 61, a gear 610 is rotatably connected to the surface of the output shaft of the motor 4, the gear 610 is meshed with the rack 69, a trigger plate 611 is fixedly connected to the other side of the rack 69, a cam 612 is fixedly connected to the surface of the output shaft of the motor 4, the surface of the cam 612 is attached to one side of the trigger plate 611, and a connecting rod 613 is fixedly connected to one end of the gear 610, and the other end of the connecting rod 613 penetrates to the inside of the protection frame 61 and is fixedly connected to the surface of the annular pipe 62.

[0027] When the output shaft of the motor 4 rotates, it will drive the cam 612 to rotate synchronously. During the process of the cam 612 rotating from the lowest point to the highest point and contacting one side of the trigger plate 611, the cam 612 will push the trigger plate 611 to move, and drive the rack 69 and the slide plate 67 to move synchronously. The spring 68 is compressed, thereby driving the gear 610 to rotate clockwise. When the gear 610 rotates, under the action of the connecting rod 613, it will drive the annular pipe 62 and the nozzle 63 to rotate synchronously. During the process of the cam 612 rotating from the highest point to the lowest point and contacting one side of the trigger plate 611, the spring 68 loses extrusion and automatically resets. When resetting, it will drive the slide plate 67, the rack 69 and the trigger plate 611 to reset synchronously, thereby driving the gear 610, the annular pipe 62 and the nozzle 63 to rotate counterclockwise and reset. Therefore, during the process of the motor 4 running to drive the grinding disc 5 to grind the metal parts, the annular pipe 62 will drive the multiple nozzles 63 to rotate reciprocally and spray the aqueous solution.

[0028] As Figure 3 and Figure 5 shown, a mounting rod 614 is fixedly connected to the surface of the output shaft of the motor 4, and the other end of the mounting rod 614 is fixedly connected to a scraping plate 615. The surface of the scraping plate 615 is attached to the inner wall of the protective frame 61. The vertical cross-section of the scraping plate 615 is an isosceles triangle.

[0029] Some debris and dust will adhere to the inner wall of the protective frame 61 after being mixed with water. When the output shaft of the motor 4 drives the grinding disc 5 to rotate, it will drive the mounting rod 614 to rotate synchronously, thereby driving the scraping plate 615 to rotate synchronously along the inner wall of the protective frame 61, scraping the dust and debris adhering to the inner wall of the protective frame 61. When the scraping plate 615 rotates to the position of the through hole 66, the scraped dust and debris will automatically fall off.

[0030] As Figure 2 shown, the through hole 66 is arranged above the filter plate 2. The dust and smaller debris are mixed with the aqueous solution and fall onto the filter plate 2 through the through hole 66, and the filter plate 2 is used for filtration so that the aqueous solution flows into the water tank 3 for repeated use.

[0031] As Figure 2 and Figure 3 shown, the connecting pipe 65 is set as a flexible pipe, and the connecting pipe 65 is a plastic component. The connecting pipe 65 can be deformed.

[0032] As Figure 4 shown, the multiple nozzles 63 are annularly distributed, and the nozzles 63 are inclined. The inclination directions of the multiple nozzles 63 all face the grinding disc 5.

[0033] When the utility model is in use and grinding metal parts, the staff holds the metal parts by hand and makes the metal parts enter the protection frame 61 to contact with the grinding disc 5. At this time, the staff starts the motor 4 and the water pump 64 simultaneously through the controller. The output shaft of the motor 4 drives the grinding disc 5 to rotate to grind the metal parts. During grinding, the protection frame 61 blocks the generated debris. Larger debris falls through the through hole 66 under the action of its own gravity. At the same time, when the water pump 64 is started, the aqueous solution in the water tank 3 will be introduced into the connecting pipe 65. After the aqueous solution enters the annular pipe 62, it sprays out from multiple nozzles 63. At the same time, when the output shaft of the motor 4 rotates, it will drive the cam 612 to rotate synchronously. Under the interaction of the cam 612 and the spring 68, when the cam 612 rotates, it will drive the rack 69 to reciprocate horizontally and drive the gear 610 to rotate reciprocally, thereby driving the annular pipe 62 and multiple nozzles 63 to rotate reciprocally to spray the aqueous solution to contact the dust and debris generated during grinding. After the dust and smaller debris are fused with the aqueous solution, they will fall through the through hole 66 onto the filter plate 2. The filter plate 2 filters it. After filtration, the aqueous solution flows into the water tank 3 for repeated use. At the same time, under the action of the mounting rod 614, it will drive the scraper 615 to rotate synchronously with the inner wall of the protection frame 61 in contact with the grinding disc 5, and scrape off the dust and debris adhering to the inner wall of the protection frame 61. When the scraper 615 rotates to the position of the through hole 66, the scraped dust and debris will automatically fall onto the filter plate 2.

[0034] It should be noted that in the above description, the motor 4 and the water pump 64 are both devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the motor 4 and the water pump 64 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
