[0002] In various optical communication devices, many peripheral devices are usually connected to transmit related signal data. In order to ensure the reliability of signal data transmission, industrial sockets have higher requirements than civilian equipment. The shape of the socket must be coordinated with the peripheral devices, resulting in some sockets with strange shapes, and some square sockets with right angles are particularly difficult to process.

[0003] The existing technology uses CNC machining center tools for processing, and the right angles are processed to R1.0 (arc with a radius of 1mm), and then the corners are cleared by electric spark machining. The production efficiency is extremely low, and the product surface is rough and black and needs to be manually polished. In addition, each processing requires an additional copper male to be processed for electric sparks. Since it is necessary to perform electric discharge machining after machining to meet the corresponding requirements, and since electric discharge machining will burn the surface, some products with high appearance requirements require further manual polishing, that is, the surface of the product that is processed by electric discharge is polished with sandpaper. Since the edges of the inner casing are irregular and there are other raised parts inside, manual polishing can easily injure hands or damage the inner casing. The operation is time-consuming and labor-intensive, resulting in high costs for batch processing, inability to improve processing efficiency, and inability to control product quality.

[0026] The present invention provides a right-angle cleaning tool for a socket. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Therefore, based on the above, we have developed a device for cleaning right angles of sockets to solve the above problems.

[0027] Please also see Figure 1 , Figure 2 and Figure 3 A right-angle cleaning jig for a socket provided in an embodiment of the present invention is mainly suitable for right-angle cleaning on a socket 101 (especially a square slot socket, or an interface) of an inner housing 100 in an optical communication device. The right-angle cleaning jig for the socket comprises a base plate 1, on which a clamping assembly, a cleaning assembly and a driving assembly are arranged, and a pneumatic valve 2 is arranged on one side of the base plate 1, the pneumatic valve 2 is pneumatically connected to the driving assembly, and the cleaning assembly is connected to the driving assembly; the clamping assembly is used to position and clamp the inner housing 100 on the base plate 1, and when the pneumatic valve 2 is opened, the driving assembly is controlled to slide, and the driving assembly drives the cleaning assembly to synchronously slide into the socket of the inner housing 100 for right-angle cleaning; when the pneumatic valve 2 is ventilated, the driving assembly is controlled to return, and the driving assembly drives the cleaning assembly to synchronously slide in the opposite direction until the cleaning assembly exits the socket of the inner housing 100.

[0028] The cleaning component is indirectly driven by the pneumatic valve 2 to clean the right angle of the socket. The operation is very simple and the cleaning can be done quickly. It can meet the needs of batch processing and cleaning of the socket, and will not cause surface burns caused by electrical discharge machining. The right angle cleaning can be completed without manually grinding the burned surface, and it will not hurt people's hands or damage the inner casing. This solves the problem that the existing right angle of the socket needs to be manually ground and the burned surface (i.e., the processing surface) is processed by electrical discharge machining, which affects the processing efficiency.

[0029] In this embodiment, the clamping assembly includes: a quick clamp 3, a clamping pad 4 and a positioning plate 5; the positioning plate 5 is fixed (screwed) on one side of the bottom plate 1 (such as Figure 2 The clamping pad 4 is fixed (screwed) on one side of the positioning plate 5 (as shown in the left and lower area). Figure 2 On one side of the longer side of the positioning plate 5 shown in the figure), the base of the quick clamp 3 is fixed (screwed) on the clamping pad 4.

[0030] The clamping pad 4 is used to fix the quick clamp 3 on the bottom plate 1, and the positioning plate 5 is used to position and fix the inner housing 100. The outer contour of the positioning plate 5 matches the shell edge of the inner housing 100, and the positioning plate 5 is provided with a plurality of slots 6 that match the protrusions 102 in the inner cavity of the inner housing 100 (used to avoid the various protrusions in the inner cavity). In this way, when the inner cavity of the inner housing 100 covers the positioning plate 5 downward, the outer contour matches the shell edge, and the inner housing 100 can completely cover the positioning plate 5 and be stuck on the positioning plate 5 in combination with the slots 6. The inner housing 100 can be further positioned and fixed by the grooves and protrusions on the outer contour. After that, the handle 7 of the quick clamp 3 can be operated to make the pressing head 8 of the quick clamp 3 descend and press, so that the inner housing 100 is clamped between the pressing head 8 and the positioning plate 5, with fast speed and good clamping effect.

[0031] In this embodiment, the cleaning assembly includes a corner cleaning knife 9, a connecting rod 10, a connecting rod pin 11, two retaining springs 12, a slider 21, two fixed blocks 22 and a sliding limit block 23; the slider 21 is installed in the groove of the base plate through the two fixed blocks 22, the blade of the corner cleaning knife 9 is inserted into the guide groove on the upper part of the slider 21, the sliding limit block 23 passes through the middle part of the corner cleaning knife 9 and is inserted into the limiting through groove 26 on the top of the slider 21, the tail of the corner cleaning knife 9 is installed between the two clamping arms of the connecting rod 10 through the connecting rod pin 11, two retaining springs 12 are installed at both ends of the connecting rod pin 11 to fix the connecting rod pin on the connecting rod, and the rod head of the connecting rod 10 is inserted into the driving assembly.

[0032] Please also read Figure 4 The specific connection method of the corner cleaning knife 9, the connecting rod 10 and the connecting rod pin 11 is: a first opening 14 is provided on the tail of the corner cleaning knife 9, and a second opening 15 adapted to the first opening is respectively provided on the two clamping arms of the connecting rod 10. The tail of the corner cleaning knife 9 is placed between the two clamping arms and the first opening is aligned with the second opening. The connecting rod pin 11 passes through the first opening and the second opening and extends out from the two second openings. Two retaining rings 12 are clamped on the annular grooves 13 at both ends of the connecting rod pin, so that the connecting rod pin can be fixed on the connecting rod.

[0033] When the driving assembly drives the connecting rod 10 forward, it drives the corner cleaning knife 9 to move forward through the guide groove in the middle of the slider 21 and insert it into the right angle for cleaning; when the driving assembly drives the connecting rod 10 backward, it drives the corner cleaning knife 9 to move backward and reset, and exit from the guide groove.

[0034] The slider 21 is installed in the groove 24 (rectangle) of the bottom plate 1 through the fixing block 22, that is, the slider 21 is placed in the groove 24, and the two fixing blocks 22 are respectively inserted into the two through grooves 24 (located on the left and right sides of the top of the slider 21) of the slider 21 and fixed (screwed) at the bottom of the groove 24, and the slider 21 can slide in the groove 24. The slider 21 is used to control the telescopic position of the corner cleaning knife 9. The blade of the corner cleaning knife 9 passes through the guide groove on the upper part of the slider 21 and is inserted into the right angle for cleaning. The height and left-right distance of the guide groove are relative to the height and left-right distance of the right angle on the bottom plate 1, so as to ensure that the corner cleaning knife 9 can be fully inserted into the right angle, and improve the position accuracy between the corner cleaning knife 9 and the right angle.

[0035] The fixed block 22 is used to fix the sliding direction of the slider 21 and limit the slider from jumping up, that is, the length of the fixed block 22 (the fixed block 22 samples a T-shaped structure, mainly the length of the horizontal top here) is smaller than the length of the through slot 23 by a preset value, so that when the slider 21 slides back and forth, it is blocked by the two ends of the top of the fixed block 22 and cannot slide anymore, thereby achieving the limitation of the slider 21.

[0036] The sliding limit block 23 is installed on the corner cleaning knife 9, and the guide groove is connected to the limit slot 26. During installation, the corner cleaning knife 9 is inserted into the guide groove, the third opening 20 opened in the middle is aligned with the limit slot 26, the lower end of the cylindrical sliding limit block 23 passes through the limit slot 26 and is inserted into the third opening 20, and the upper end of the sliding limit block 23 is in the limit slot 26, so that the sliding limit block 23 can slide back and forth in the limit slot 26. Since the lower end of the sliding limit block 23 is inserted into the corner cleaning knife 9, when the upper end of the sliding limit block 23 is blocked by the two ends of the limit slot 26, the corner cleaning knife 9 can no longer extend forward or backward, thereby limiting the extension position of the corner cleaning knife 9 and preventing the corner cleaning knife 9 from extending too long and damaging other structures in the inner housing 100.

[0037] The corner cleaning knife 9 is used to clean the R corner (rounded corner), C foot (45 degree angle) or irregular steps left after the socket processing; the connecting rod 10 is used to fix the corner cleaning knife 9 and drive the corner cleaning knife 9 to slide according to the action of the driving component. Please refer to Figure 5 and Figure 6 , Figure 6 The three middle figures in the figure are, from top to bottom, a side view of the corner cleaning knife 9 (the blade 19 faces downward), a bottom view, and another side view (the blade 19 faces upward), the left side is a left view (a schematic cross-sectional view of the blade edge), and the right side is a right view (a schematic cross-sectional view of the blade tail).

[0038] The contour of the corner cleaning knife 9 is the same as that of the right angle, but the size is slightly smaller so that it can be inserted into the right angle along the inner wall of the right angle, that is, there is a clearance fit between the corner cleaning knife 9 and the right angle, and the clearance (single-side clearance) between the corner cleaning knife 9 and the right angle is between 0.02 and 0.05 mm. In this way, the corner cleaning knife can be inserted into the right angle for plunge milling to complete the cleaning of the right angle. Figure 1 Taking the socket 101 shown as an example, the corner cleaning knife 9 includes a knife body 16, an upper knife 17 and a lower knife 18; the arc-shaped protrusion on the lower side of the upper knife 17 is fixed in the arc-shaped groove on the upper side of the knife body 16, and the arc-shaped protrusion on the upper side of the lower knife 18 is fixed in the arc-shaped groove on the lower side of the knife body 16, and a long strip of protruding blade 19 is provided on the lower side of the lower knife 18; the width of the upper knife 17 and the lower knife 18 are both smaller than the width of the knife body 16 by a preset value W, so that a step surface is formed on the upper and lower sides of the knife body 16 respectively, the first opening 14 passes through the upper knife and the knife body, and the third opening 20 passes through the upper knife, the knife body, the lower knife and the blade. Figure 6 As shown, the blade body 16 and the blade 19 at the end of the blade are both recessed inwards, so that the sharp angle or arc formed is more convenient for cleaning; the end of the blade tail is a plane.

[0039] In order to prevent the slider 21 from continuing to extend forward when it extends to the sliding limit block 23, causing the slider 21 to loosen, the cleaning assembly also includes two springs 27 and a spring pressure plate 28. One ends of the two springs 27 are respectively inserted into the spring holes on the left and right sides of the lower part of the slider 21, and one side of the groove 24 is provided with a spring groove 31 which is narrower than the groove 24. The other ends of the two springs 27 extend from the slider 21 and are placed in the spring groove 31. The spring pressure plate 28 covers the spring and is fixed on the pressure plate groove 31 (that is, there are two screw holes in the pressure plate groove 31, and the spring pressure plate 28 is screwed and fixed to the pressure plate groove 31 and clamps the other end of the spring in the middle).

[0040] The elastic force of the spring 27 can hold the slider 21, so that the slider 21 can effectively contact the inner housing 110 and not loosen. The spring pressure plate 28 is used to cover the spring to prevent the spring from jumping out.

[0041] Please continue reading Figure 2 and Figure 3 The driving assembly includes a cylinder 29 and a support plate 30. The cylinder 29 is fixed (screwed) on the support plate 30. The support plate 30 is fixed (screwed) in the inclined groove 32 of the base plate and abuts against the corner column 25 on a corner of the base plate. The rod head of the connecting rod 10 is inserted into the mounting hole of the cylinder 29.

[0042] The pneumatic valve controls the cylinder to push or retract the connecting rod, and the connecting rod can drive the corner cleaning knife to extend and retract. The support plate 30 is used to fix the cylinder. The height of the inclined groove 32 is equal to or less than (a few millimeters less) the height from the bottom of the cylinder 29 to the bottom of the mounting hole, so that the cylinder can drive the connecting rod 10 to extend and retract on the bottom plate, and the groove wall of the inclined groove 32 can be used to support the cylinder to prevent the cylinder from shifting when working.

[0043] Please continue reading Figures 1 to 6 The processing principle of the socket right angle cleaning jig is as follows: first, the inner cavity of the inner housing 100 is downwardly covered with the positioning plate 5, and the handle 7 of the quick clamp 3 is operated to lower the pressing head 8, and the inner housing 100 is clamped between the pressing head 8 and the positioning plate 5. Then, the pneumatic valve is opened, and the cylinder 29 pushes the connecting rod to slide, driving the slider and the corner cleaning knife 9 to slide until the corner cleaning knife 9 is inserted into the right angle of the socket of the inner housing. When the corner cleaning knife is inserted, the R angle, C foot or irregular step can be cleaned.

[0044] When the pneumatic valve is ventilated, the cylinder retracts the connecting rod, driving the slider and the corner cleaning knife to retreat together, and the corner cleaning knife is removed from the socket. The operating handle 7 makes the pressing head 8 rise, and the inner housing can be taken out. If the cleaning effect is not good after checking, the inner housing can be put in again, and the pneumatic valve can be controlled multiple times to make the corner cleaning knife inserted and withdrawn multiple times for multiple cleaning.

[0045] In summary, the present invention provides a socket right-angle cleaning jig, which only requires placing the inner casing into the positioning block, fixing the inner casing with a quick clamp, and then opening the pneumatic valve. The cylinder drives the angle cleaning tool to extend into the right angle for milling to achieve the angle cleaning function. After closing the pneumatic valve, the cylinder is reset and the inner casing can be taken out. Compared with the existing angle cleaning method of electrical discharge machining, there is no need to process a copper rod separately or manually polish the machining surface. It is easy to operate and has a fast cleaning speed, which greatly improves work efficiency. The surface finish of the machining is better than that of electrical discharge machining. One angle cleaning tool can process tens of thousands of products, which is suitable for batch processing, thereby reducing processing costs.

[0046] The division of the above functional modules is only for illustration. In practical applications, the above functions can be assigned to different functional modules as needed, that is, divided into different functional modules to complete all or part of the functions described above.

[0047] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
