Description

[0001] The invention belongs to the technical field of polishing devices, and in particular relates to a polishing device for a circular shell of an electronic product. Background Art

[0002] Electronic products are products that use electricity as the basis for their work. Watches, smart phones, televisions, etc. are all electronic products. In the production and processing of electronic products such as watches, their shells are often circular, and the existing grinding equipment has the following technical problems when grinding circular shells:

[0003] 1. When grinding, a flat grinding plate is usually used. When grinding a circular shell, it cannot fit the circular shell well, resulting in a low utilization rate of the grinding plate. Only the middle part that is in close contact with the circular shell can be used to grind the circular shell, which reduces the grinding efficiency and effect.

[0020] Compared with the existing technology, the advantages of this electronic product round shell grinding equipment are:

[0021] 1. The present invention provides a fitting mechanism. During grinding, the first motor drives the screw to rotate, further driving the two moving blocks to approach each other. Under the action of the connecting rod, the two telescopic plates are brought close to the circular shell, and the grinding sandpaper is abutted against the circular shell. Thereafter, the two moving blocks continue to approach the circular shell, and the telescopic plates shrink due to the abutment of the circular shell. The two abutting wheels on both sides of the telescopic plates continue to approach the circular shell, and the two swinging plates swing to ensure that the abutting wheels are in close contact with the circular shell, so that the grinding sandpaper can be bent into an arc that completely fits the circular shell, thereby preventing dead angles during grinding and improving the grinding efficiency and effect of the circular shell.

[0022] 2. The present invention sets a positioning mechanism. When the two moving blocks approach each other, the two racks are driven to approach each other through the extension rod, and the two rotating rods are driven to rotate, so that the two positioning plates are swung close to the circular shell and abut against the two sides of the circular shell. At the same time, under the action of the second hinge seat, the third hinge seat and the connecting rod, the control block is driven to move, and the C-shaped plate is driven to move through the U-shaped rod, so that the positioning roller in the C-shaped plate is able to cling to the side of the circular shell away from the two positioning plates, and the circular shell can be clamped and fixed in a triangular shape, thereby improving the fixing effect of the circular shell, preventing the circular shell from shaking during the grinding process, and further improving the grinding effect of the circular shell.

[0023] 3. The present invention sets a reciprocating mechanism. During grinding, the positioning roller is driven to rotate by the second motor and the second gear. Since the positioning roller is in close contact with the circular shell, the circular shell can be driven to rotate by the friction force, so as to facilitate comprehensive grinding of the circular shell. At the same time, the rotation of the positioning roller drives the rotating plate to rotate, and the reciprocating contact of the rotating plate pushes the two moving rods, driving the two guide wheels to reciprocate. The telescopic plate is pulled back and forth by the L-shaped rod to retract, so that the center position of the grinding sandpaper is intermittently in close contact with the circular shell. In this process, air reciprocates between the grinding sandpaper and the circular shell. The debris is cleaned in time by the flow of air between the grinding sandpaper and the circular shell, so as to prevent the debris from scratching the circular shell.

DETAILED DESCRIPTION

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] like Figure 1-Figure 7 As shown, a device for polishing a circular housing of an electronic product comprises:

[0034] A grinding platform 1, wherein two support blocks 11 are provided on the grinding platform 1, a screw rod 12 is provided between the two support blocks 11, and the spiral directions of the threads on both sides of the screw rod 12 are opposite, a first motor 13 is provided on the support block 11, and the output shaft of the first motor 13 is fixedly connected to the screw rod 12;

[0035] Two fitting mechanisms 2 are provided on the polishing platform 1, and the fitting mechanisms 2 are used to polish the circular shell more closely;

[0036] A positioning mechanism 3 is provided on the polishing platform 1, and the positioning mechanism 3 is used to more firmly position and fix the circular shell;

[0037] A reciprocating mechanism 4 is also provided on the grinding platform 1, and the reciprocating mechanism 4 is used to discharge the debris generated during grinding in time.

[0038] Each laminating mechanism 2 comprises a moving block 21, a connecting rod 22, a telescopic plate 23, a grinding sandpaper 24, two first articulated seats 25, two swinging plates 26, two first springs 27 and two abutting wheels 28. The moving block 21 is slidably mounted on the grinding platform 1. The moving block 21 is threadedly connected to a thread on one side of the screw rod 12. A telescopic plate 23 is mounted on the moving block 21 through the connecting rod 22. A grinding sandpaper 24 is provided at one end of the telescopic plate 23 away from the connecting rod 22. First articulated seats 25 are provided on both sides of the telescopic plate 23. A swinging plate 26 is hinged on each first articulated seat 25. Each swinging plate 26 is elastically connected to the side wall of the telescopic plate 23 through the first spring 27. An abutting wheel 28 is rotatably mounted on one end of each swinging plate 26 close to the grinding sandpaper 24.

[0039] In view of the problem that in the prior art, when grinding a circular shell, the flat grinding plate cannot fit the circular shell well, resulting in a low utilization rate of the grinding plate, and only the middle part that is in close contact with the circular shell can grind the circular shell, which reduces the grinding efficiency and grinding effect. The present invention provides a fitting mechanism 2. During grinding, the first motor 13 drives the screw rod 12 to rotate, further driving the two moving blocks 21 to approach each other, and under the action of the connecting rod 22, the two telescopic plates 23 are brought close to the circular shell, and the grinding sandpaper 24 is abutted against the circular shell. Thereafter, the two moving blocks 21 continue to approach the circular shell, and the telescopic plates 23 shrink due to the abutment of the circular shell. The two abutting wheels 28 on both sides of the telescopic plates 23 continue to approach the circular shell, and the two swinging plates 26 swing to ensure that the abutting wheels 28 are in close contact with the circular shell. The grinding sandpaper 24 can be bent into an arc that completely fits the circular shell through the abutting wheels 28, thereby preventing dead angles during grinding and improving the grinding efficiency and grinding effect of the circular shell.

[0040] The positioning mechanism 3 includes two rotating rods 31, two first gears 32, two positioning plates 33, two extension rods 34, two racks 35, two second hinge seats 36, a control block 37, two third hinge seats 38, two connecting rods 39, a C-shaped plate 310, a U-shaped rod 311 and a positioning roller 312. The two rotating rods 31 are rotatably mounted on the grinding platform 1, each rotating rod 31 is provided with a first gear 32, each rotating rod 31 is provided with a positioning plate 33, and the two moving blocks 21 are both provided with racks through the extension rods 34. 35, the two racks 35 are respectively meshed with the two first gears 32, and the two racks 35 are each provided with a second hinge seat 36. A control block 37 is slidably installed on the grinding platform 1, and a third hinge seat 38 is provided on the two side walls of the control block 37. Connecting rods 39 are hinged between the two second hinge seats 36 and the two third hinge seats 38. A C-shaped plate 310 is slidably installed on the grinding platform 1, and the C-shaped plate 310 is connected to the control block 37 through a U-shaped rod 311, and a positioning roller 312 is rotatably installed in the C-shaped plate 310.

[0041] Among them, a second motor 5 is provided above the C-shaped plate 310, and a second gear 6 is provided on the output shaft of the second motor 5 and the roller shaft of the positioning roller 312. The two second gears 6 are meshed with each other. When the circular outer shell is polished, the roller shaft of the positioning roller 312 can be driven to rotate by the second motor 5 and the two second gears 6, so that the circular outer shell is driven to rotate by the friction force between the positioning roller 312 and the circular outer shell, and the circular outer shell is comprehensively polished.

[0042] Among them, two slide grooves 7 are opened on the grinding platform 1, and the two ends of the U-shaped rod 311 are slidably installed on the inner walls of the two slide grooves 7, respectively, ensuring that the control block 37, the U-shaped rod 311 and the C-shaped plate 310 can be displaced synchronously.

[0043] The two racks 35 are staggered to avoid motion interference when the two racks 35 are close to each other.

[0044] In view of the problem that the fixing effect of the circular shell in the prior art is poor, which makes the circular shell easy to shake and further reduces the polishing effect of the circular shell, the present invention is provided with a positioning mechanism 3. When the two moving blocks 21 are close to each other, the two racks 35 are driven to approach each other through the extension rod 34. Further, under the action of the first gear 32, the two rotating rods 31 are driven to rotate, so that the two positioning plates 33 can swing close to the circular shell and abut against the two sides of the circular shell. At the same time, the two racks 35 are close to each other, which will be connected between the second hinge seat 36, the third hinge seat 38 and the connecting rod Under the action of 39, the control block 37 is displaced, and the C-shaped plate 310 is displaced through the U-shaped rod 311, so that the positioning roller 312 in the C-shaped plate 310 can be close to the side of the circular shell away from the two positioning plates 33, and can clamp and fix the circular shell in a triangular shape, thereby improving the fixing effect of the circular shell, preventing the circular shell from shaking during the polishing process, and further improving the polishing effect of the circular shell. The fixing work of the circular shell and the fitting work of the polishing sandpaper are carried out simultaneously, without the need to set up an additional driving source, thereby improving work efficiency and saving polishing costs.

[0045] The reciprocating mechanism 4 includes two guide rails 41, two guide blocks 42, two baffles 43, two second springs 44, two L-shaped rods 45, two guide wheels 46, a rotating plate 47 and two moving rods 48. The two guide rails 41 are arranged above the grinding platform 1. A guide block 42 is slidably installed on each guide rail 41. A baffle 43 is provided on each guide rail 41. Each guide block 42 is elastically installed on the baffle 43 through the second spring 44. A guide wheel 46 is rotatably installed on each telescopic plate 23 through the L-shaped rod 45. Each guide wheel 46 rolls in contact with the guide block 42 at the corresponding position. A rotating plate 47 is provided on the part of the positioning roller 312 that extends from the roller shaft above the C-shaped plate 310. A moving rod 48 is provided at one end of each guide block 42 close to the rotating plate 47. The rotating plate 47 intermittently contacts the two moving rods 48.

[0046] Among them, two fixed plates 8 are provided on the grinding platform 1, and each fixed plate 8 is elastically installed with a support plate 82 through a third spring 81. The two support plates 82 are respectively connected to the two guide rails 41 through two fixing rods 83. In actual use, the two support plates 82 will abut against the two sides of the circular shell. Therefore, the positions of the two support plates 82 can be adjusted according to the size of the circular shell, and the positions of the two guide rails 41 can be further adjusted by the fixing rod 83, so that when the telescopic plate 23 is used to fit the sandpaper 24 on circular shells of different sizes, the change in the position of the guide wheel 46 on the telescopic plate 23 is synchronized with the change in the position of the two guide rails 41, thereby ensuring the coordination between the guide block 42 and the guide wheel 46 on the guide rail 41.

[0047] In view of the problem that the debris generated by grinding in the prior art is easily sandwiched between the grinding sandpaper 24 and the shell, and scratches are generated on the circular shell during the subsequent grinding process, the present invention is provided with a reciprocating mechanism 4. During grinding, the positioning roller 312 is driven to rotate by the second motor 5 and the second gear 6. Since the positioning roller 312 is in close contact with the circular shell, the circular shell can be driven to rotate by the action of friction, so that the circular shell can be fully polished. At the same time, the rotation of the positioning roller 312 drives the rotating plate 47 to rotate, and the reciprocating contact of the rotating plate 47 pushes the two moving rods 48, so that the two guide blocks 42 can reciprocate on the guide rail 41. When the guide block 42 moves, the guide wheel 46 is pushed, so that the two guide wheels 46 are reciprocated (when the rotating plate 47 abuts and pushes the moving rod 48 When moving, the inclined surface of the guide block 42 will squeeze and push the guide wheel 46, so that the guide wheel 46 can be displaced. When the rotating plate 47 no longer abuts against the pushing moving rod 48, the guide block 42 returns to its original position under the elastic force of the second spring 44, and the guide wheel 46 can also return to its original position). The telescopic plate 23 is pulled back and forth by the L-shaped rod 45 to reciprocate, so that the center position of the grinding sandpaper 24 is intermittently close to the circular shell. During this process, air reciprocates between the grinding sandpaper 24 and the circular shell, and is reciprocatedly discharged from between the grinding sandpaper 24 and the circular shell. Through the flow of air between the grinding sandpaper 24 and the circular shell, debris can be intermittently discharged from between the grinding sandpaper 24 and the circular shell, and the debris is cleaned in time to prevent the debris from scratching the circular shell.

[0048] The present invention can be explained by the following operation mode:

[0049] During grinding, the circular shell is placed on the grinding platform 1, and then the first motor 13 is turned on to drive the screw 12 to rotate, driving the two moving blocks 21 to approach each other, so that the two telescopic plates 23 are close to the circular shell, and the grinding sandpaper 24 is abutted against the circular shell. Thereafter, the two moving blocks 21 continue to approach the circular shell, and the telescopic plates 23 shrink due to the abutment of the circular shell. The two abutting wheels 28 on both sides of the telescopic plates 23 continue to approach the circular shell, and the two swinging plates 26 swing to ensure that the abutting wheels 28 are in close contact with the circular shell. The grinding sandpaper 24 is bent by the abutting wheels 28 into an arc that completely fits the circular shell, thereby improving the grinding efficiency and grinding effect.

[0050] When the two moving blocks 21 approach each other, the two racks 35 are driven to approach each other through the extension rod 34. Under the action of the first gear 32, the two rotating rods 31 are driven to rotate, so that the two positioning plates 33 can swing close to the circular shell and abut against the two sides of the circular shell. At the same time, the two racks 35 approach each other, and under the action of the second hinge seat 36, the third hinge seat 38 and the connecting rod 39, the control block 37 is driven to move, and the C-shaped plate 310 is driven to move through the U-shaped rod 311, so that the positioning roller 312 in the C-shaped plate 310 can be close to the side of the circular shell away from the two positioning plates 33, and the circular shell can be clamped and fixed in a triangular shape to prevent the circular shell from shaking during the grinding process.

[0051] After the above preparations are completed, the second motor 5 is turned on to drive the positioning roller 312 to rotate through the two second gears 6. The circular shell is driven to rotate synchronously through the friction force, so as to facilitate the comprehensive polishing of the circular shell.

[0052] At the same time, the rotation of the positioning roller 312 drives the rotating plate 47 to rotate, and the reciprocating contact of the rotating plate 47 pushes the two moving rods 48, so that the two guide blocks 42 can be reciprocated on the guide rail 41. The guide block 42 pushes the guide wheel 46 when it is displaced, so that the two guide wheels 46 are reciprocated. The telescopic plate 23 is pulled back and forth by the L-shaped rod 45 to reciprocate, so that the center position of the grinding sandpaper 24 is intermittently close to the circular shell. In this process, air reciprocates and enters between the grinding sandpaper 24 and the circular shell, and is reciprocated and discharged from between the grinding sandpaper 24 and the circular shell, so that debris can be intermittently discharged from between the grinding sandpaper 24 and the circular shell, and the debris is cleaned in time.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
