Description

Technical Field

[0001] The invention relates to the technical field of mobile phone shell hole turning, in particular to a mobile phone shell hole turning device capable of reducing the scattering of waste materials. Background Art

[0002] In the process of producing mobile phone cases, in order to ensure the normal use of the original functions of the mobile phone such as shooting and charging, it is usually necessary to drill holes in some key parts.

[0003] When drilling a hole in a mobile phone case, part of the material of the mobile phone case is removed by the cutting action of the drill bit to form a drill hole. In this process, due to the chip force of the drill bit, part of the removed waste material will splash and pop out at a certain speed and direction, and then scatter on the surface of the operating table and the mobile phone case. The scattered smaller waste particles may enter the inside of the hole-turning device, causing the operation of the device to be obstructed, affecting production efficiency. At the same time, it is usually necessary to drill multiple holes on the surface of the mobile phone case. A large amount of waste material scattered on the surface of the mobile phone case will hinder the next drilling, reduce the drilling accuracy, and also damage the drill bit itself.

[0004] At the same time, different mobile phone cases have different hardnesses, and mobile phone cases of different materials have different requirements for drilling effects. Therefore, when drilling holes in mobile phone cases, different drill bits need to be selected according to the different materials of the mobile phone cases. In the prior art, the previously installed drill bit is usually removed before drilling holes, and then a suitable drill bit is installed, which makes the drill bit replacement process cumbersome and inconvenient to manage the drill bit, and increases the risk of losing the drill bit during the disassembly and assembly process.

[0005] In addition, during the operation of the drill bit, the drill tip of the drill bit will produce friction with the mobile phone case, which will cause wear of the drill bit. Therefore, the drill tip of the drill bit needs to be lubricated. At the same time, when the drill bit runs at high speed, the friction between the drill bit and the mobile phone case will increase, thereby causing the drill bit to wear more severely. At this time, the drill bit has a greater demand for lubricating oil. When running at a lower speed, the friction between the drill bit and the mobile phone case is smaller, and the drill bit has a relatively smaller demand for lubricating oil. If the drill bits at different speeds are lubricated equally, there will be a situation where the drill bit lubrication demand cannot be met or the lubricating oil is wasted.

[0006] Therefore, a mobile phone shell hole-turning device capable of reducing the scattering of waste is proposed. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By arranging a variety of drill bits inside the hole turning device and being able to replace the drill bits by turning a knob, the appropriate drill bit can be selected according to the material of the mobile phone case without disassembling and installing the drill bit, thereby facilitating the management of the drill bit and avoiding the loss of the drill bit during the replacement process. At the same time, when the drill bit is not working, the drill bit is stored inside the main box, thereby protecting the drill bit from the influence of the external environment and extending the service life of the drill bit. Compared with the existing drilling device that needs to remove the drill bit and store it properly when not working, the storage operation of the drill bit is more convenient and the safety of the storage operation is improved. In addition, the cleaning block can be driven to fit the surface of the drill bit to rotate and clean the drill bit as the drill bit extends and retracts and resets, thereby reducing the cleaning dead angle, thereby avoiding the impurities on the surface of the drill bit from affecting the hole turning accuracy of the drill bit. At the same time, the drill bit can be cleaned in time after the drill bit is used, thereby avoiding the difficulty of cleaning due to the long residence time of impurities.

[0018] 2. During the rotation of the drill bit, the suction port of the dust suction pipe reciprocates around the drill bit, thereby covering more areas around the drill bit, making the dust suction work more comprehensive and reducing the scattering of waste chips. At the same time, the fixed frame can intercept the waste generated by drilling holes, reducing the scattering area of ​​the waste, so that the dust suction pipe can collect the waste in a centralized manner. In addition, the unidirectional rotation of the baffle controlled by the suction force can prevent the waste inside the dust suction pipe from falling on the surface of the workbench again when the suction force is insufficient, thereby ensuring the dust suction effect;

[0019] 3. The centrifugal force generated when the drill bit rotates is used to separate the sealing blocks from each other, so that the lubricating oil in the oil storage tank can enter the lubrication tank to lubricate the drill tip of the drill bit in real time, thereby reducing the wear of the drill bit during hole turning. The outlet of the oil storage tank is set in a funnel shape, which can guide the flow of the lubricating oil and make it enter the lubrication tank more smoothly. At the same time, when the drill bit rotates at high speed, the distance between the two sealing blocks is larger, and more lubricating oil can enter the lubrication tank. When the drill bit rotates at a lower speed, the distance between the two sealing blocks is smaller, and less lubricating oil can enter the lubrication tank, thereby meeting the lubrication needs of the drill bit while avoiding the waste of lubricating oil.

[0048] Wherein: the dust suction pipe 89 is configured as a hose.

[0049] The above implementation works as follows:

[0050] The initialization steps are as follows:

[0051] The staff places the mobile phone case to be drilled on the mobile phone case placement rack on the top of the workbench 1. At this time, the drill bit 514 is located inside the rotating long tube 510, and the two blocking blocks 74 fit each other.

[0052] The working steps are as follows:

[0053] The following is an explanation of the process of replacing the drill bit 514 by replacing the components:

[0054] like Figures 1 to 7 As shown, when the staff needs to select different drill bits 514 according to the material of the mobile phone case, the knob 56 can be rotated. The rotation of the knob 56 drives the starting turntable 53 fixedly connected thereto to rotate, and the rotation of the starting turntable 53 drives the push plate 54 and the tooth groove 55 thereon to rotate synchronously. When the push plate 54 moves to conflict with the short column 59, the rotation of the push plate 54 will drive the linkage rotating plate 57 to rotate by pushing the short column 59. At this time, the tooth groove 55 and the tooth block 58 will mesh with each other, and the rotation of the starting turntable 53 will drive the linkage rotating plate 57 to continue to rotate through the tooth block 58. When the tooth groove 55 moves to no longer mesh with the tooth block 58, the linkage rotating plate 57 stops rotating. At this time, the linkage The rotating plate 57 rotates a quarter of a circle, and the rotating long tube 510 is located inside the linked rotating plate 57. The rotation of the linked rotating plate 57 drives the rotating long tube 510 to synchronously rotate a quarter of a circle around the center of the linked rotating plate 57. The next rotating long tube 510 and the drill bit 514 therein rotate to a position close to the slide plate 518. The staff can continuously rotate to select a suitable drill bit 514, and then replace the drill bit 514 by turning the knob 56. There is no need to disassemble and install the drill bit 514, and the suitable drill bit 514 can be selected according to the material of the mobile phone case, thereby facilitating the management of the drill bit 514 and avoiding the loss of the drill bit 514 during the replacement process.

[0055] After the drill bit 514 is selected, the staff presses the pressing plate 522 downward, and the downward movement of the pressing plate 522 drives the telescopic tube 516 to extend downward. Since the shape of the connecting portion between the rotating long tube 510 and the inside of the storage box 52 is set to be square, the shape of the connecting portion between the rotating long tube 510 and the inside of the storage box 52 is adapted to the shape of the bottom of the telescopic tube 516. At the same time, since the telescopic tube 516 is always located above a rotating long tube 510 close to the slide plate 518, when the telescopic tube 516 extends downward, the bottom of the telescopic tube 516 will enter the interior of a rotating long tube 510 close to the slide plate 518 and be clamped with the rotating long tube 510. The downward movement of the telescopic tube 516 in the rotating long tube 510 pushes the replacement push rod 512 to slide downward inside the linkage plate 511 The push rod 512 is replaced by the push rod 513, which slides downward and stretches the reset spring 515. The downward sliding of the connecting rod 513 drives the drill bit 514 to slide downward and extend out of the main body box 51. At the same time, the downward movement of the pressing plate 522 drives the slide plate 518 to slide downward inside the fixing frame 517 and compress the clamping spring 521. Due to the edge restriction of the lower groove a, the downward sliding of the slide plate 518 causes the rotating rod 520 to slide at one end inside the clamping groove 519 into the interior of the growing groove b, and enters the interior of the upper groove c along the growing groove b and clamps with the slide plate 518, thereby limiting the movement of the pressing plate 522, avoiding accidental movement of the pressing plate 522 during the operation of the hole turning device, and ensuring the smooth progress of the hole turning work.

[0056] After the drill bit 514 is fully extended, the staff starts the external power supply. At this time, the electric telescopic arm 4 drives the drill bit 514 to move to the position where the hole needs to be drilled. At the same time, the external motor of the telescopic tube 516 starts to drive the telescopic tube 516 to start rotating. Because the shape of the connecting part between the rotating long tube 510 and the inside of the storage box 52 is compatible with the shape of the bottom of the telescopic tube 516 and is set to a square, at this time, because the edges and corners of the square provide support, the rotation of the telescopic tube 516 drives the rotating long tube 510 to rotate inside the storage box 52, and the rotation of the rotating long tube 510 drives the linkage plate 511 to rotate synchronously. Because the inner wall shape of the linkage plate 511 is compatible with the outer wall shape of the replacement push rod 512 and is set to a square, the rotating long tube 510 drives the replacement push rod 512 to rotate synchronously through the linkage plate 511, and the rotation of the replacement push rod 512 drives the drill bit 514 to rotate synchronously through the connecting rod 513 to rotate the mobile phone case.

[0057] When the hole-turning device is used up, the electric telescopic arm 4 drives the main box 51 to return to its original position, and the external motor of the telescopic tube 516 is powered off. At this time, the staff presses the pressing plate 522 downward, and the downward movement of the pressing plate 522 drives the slide plate 518 to slide downward inside the fixed frame 517. Due to the limitation of the groove wall shape at the upper groove c, the downward sliding of the slide plate 518 will cause the rotating rod 520 to slide at one end inside the clamping groove 519 into the growing groove d, and enter the lower groove a along the growing groove d. At this time, under the elastic extension action of the clamping spring 521, the slide plate 518 slides upward inside the fixed frame 517, and the upward sliding of the slide plate 518 drives the pressing plate 522 to move upward. The upward movement of the pressing plate 522 drives the telescopic tube 516 to retract upward and leave the interior of the rotating long tube 510. At this time, under the elastic contraction action of the reset spring 515, the connecting rod 513 drives the drill bit 514 to move upward and enter the interior of the rotating long tube 510. Furthermore, when the drilling device is not in use, the drill bit 514 is located inside the main body box 51, thereby protecting the drill bit 514 from the influence of the external environment, extending the service life of the drill bit 514. Compared with the existing drilling device that needs to remove the drill bit 514 and properly store it when not working, the storage operation of the drill bit 514 is more convenient and the safety of the storage operation is improved.

[0058] The following is an explanation of the process of cleaning the surface of the drill bit 514 by the cleaning component:

[0059] like Figures 3 to 5 As shown, when the pressing plate 522 is pressed to drive the drill bit 514 to extend downward, the downward movement of the pressing plate 522 drives the cleaning push rod 66 fixedly connected thereto to slide downward inside the storage box 52. Since the top of the linkage rod 64 is located on the moving path of the cleaning push rod 66, the downward sliding of the cleaning push rod 66 will push the linkage rod 64 to slide downward inside the fixed plate 61 and compress the cleaning spring 65. The sliding of the linkage rod 64 causes the end of the linkage rod 64 located inside the arc groove 63 to have a tendency to move downward. The downward movement tendency of the linkage rod 64 will cause it to contact the groove wall of the arc groove 63, causing the cleaning block 62 to rotate. The rotation of the cleaning block 62 drives the soft brush inside it to rotate synchronously, and then, in the process of the drill bit 514 extending downward, the soft brush inside the cleaning block 62 can rotate and clean against the surface of the drill bit 514. Since the cleaning block 62 is detachably installed inside the fixed plate 61, the staff can replace the cleaning block 62, thereby ensuring the cleaning effect of the cleaning block 62 on the drill bit 514.

[0060] When the drill bit 514 moves upward and enters the rotating long tube 510, the upward movement of the pressing plate 522 drives the cleaning push rod 66 to move upward. The upward movement of the cleaning push rod 66 makes it no longer conflict with the linkage rod 64. At this time, under the elastic extension of the cleaning spring 65, the linkage rod 64 slides upward inside the fixed plate 61, and the upward sliding of the linkage rod 64 makes it reversely conflict with the groove wall of the arc groove 63, causing the cleaning block 62 to rotate in the opposite direction. Then, during the upward resetting of the drill bit 514, the soft brush inside the cleaning block 62 can rotate and clean the surface of the drill bit 514, and then, as the drill bit 514 extends and retracts and resets, the cleaning block 62 can be driven to rotate and clean the drill bit 514 in accordance with the surface of the drill bit 514, thereby reducing the cleaning dead angle and avoiding the impurities on the surface of the drill bit 514 affecting the drilling accuracy of the drill bit 514. At the same time, the drill bit 514 can be cleaned in time after use to avoid the difficulty of cleaning due to the impurities staying for too long.

[0061] The following is an explanation of the process of lubricating the drill tip with the lubrication assembly:

[0062] like Figures 8 to 10 As shown, when the drill bit 514 is fully extended, the oil filling hole on the connecting rod 513 is located outside the main box 51, and the staff can inject the lubricating oil into the oil storage tank 71 through the oil filling hole on the connecting rod 513. During the rotation of the drill bit 514, the rotation of the connecting rod 513 will apply centrifugal force to the blocking block 74 inside the long groove 72, so that the two blocking blocks 74 move away from each other and compress the lubricating spring 73. At this time, the oil storage tank 71 and the lubrication groove 75 are connected to each other, and the lubricating oil in the oil storage tank 71 enters the lubrication groove 75 to lubricate the drill tip of the drill bit 514 in real time, thereby reducing the wear of the drill bit 514 during the hole turning process. It is funnel-shaped, which can guide the flow of lubricating oil so that it can enter the interior of the lubrication groove 75 more smoothly. At the same time, when the drill bit 514 rotates at a high speed, the distance between the two blocking blocks 74 is larger, and more lubricating oil can enter the interior of the lubrication groove 75. When the drill bit 514 rotates at a lower speed, the distance between the two blocking blocks 74 is smaller, and less lubricating oil can enter the interior of the lubrication groove 75, thereby being able to meet the lubrication needs of the drill bit 514 while also avoiding the waste of lubricating oil. When the connecting rod 513 stops rotating, under the elastic extension action of the lubrication spring 73, the blocking block 74 slides and resets inside the long groove 72, and the two blocking blocks 74 fit each other again.

[0063] The following is a description of the process of reducing waste residue in the dust collection component:

[0064] like Figure 2As shown, the rotation of the telescopic tube 516 drives the starting rod 81 to rotate inside the main box 51 through the interlocking belt 82 connected to it, and the rotation of the starting rod 81 drives the interlocking push rod 83 to rotate synchronously. The rotation of the interlocking push rod 83 causes the end of the interlocking push rod 83 away from the starting rod 81 to slide back and forth inside the reciprocating groove 85 and push the tooth plate 84 to move back and forth inside the main box 51. The back and forth reciprocating movement of the tooth plate 84 will drive the gear plate 86 meshing with it to rotate back and forth, and the reciprocating rotation of the gear plate 86 drives the limiting plate 87 to rotate back and forth.

[0065] like Fig.11 and Fig.12 The reciprocating rotation of the limiting plate 87 shown will drive the suction port of the dust suction pipe 89 to reciprocate around the drill bit 514, thereby covering more areas around the drill bit 514, making the dust suction work more comprehensive and reducing the scattering of waste chips. At the same time, the fixed frame 517 is arranged to intercept the waste generated by the hole rotation, reducing the scattering area of ​​the waste, so that the dust suction pipe 89 can collect the waste in a centralized manner. At the same time, due to the outer wall restriction at the suction port of the dust suction pipe 89, the baffle 810 can only rotate toward the inside of the dust suction pipe 89. When the suction force generated by the vacuum cleaner 88 is large enough, the baffle 810 rotates open to suck the waste generated by the hole rotation into the vacuum cleaner 88 through the dust suction pipe 89. When the vacuum cleaner 88 is turned off or the suction force gradually decreases due to a malfunction, the baffle 810 rotates closed, and the waste that has not completely entered the vacuum cleaner 88 in the dust suction pipe 89 will not fall on the surface of the workbench 1 again, thereby ensuring the dust suction effect.
