[0002] As a key component of lamps, an LED lampshade is usually composed of two parts, i.e. a base cover for mounting and fixing LED lamp beads and a driving circuit, and a light-transmitting cover covering the base cover and used for transmitting light and protecting the lamp beads, the sidewall of the base cover is usually designed as a relatively thin wall structure to meet specific installation space or heat dissipation requirements.
[0003] The side thin wall position of the base cover needs to be processed to reserve mounting holes or wire holes, and the smoothness of the hole edges of these holes is crucial, if burrs or deformation exist on the hole edges after drilling, not only the insulation layer of the wire passing through will be scratched, causing the risk of short circuit, but also the installation effect of the subsequent waterproof sealing element will be affected, leading to the decline or even failure of the sealing performance of the lamp.

DETAILED DESCRIPTION
[0036] The embodiments of the present application are described in detail below. The embodiments described below are exemplary only, and are not intended to be limiting of the present application. Unless otherwise indicated, technical or scientific terms used in the embodiments have the same meaning as commonly understood by one of ordinary skill in the art to which the present application pertains.
[0037] Reference Figure 1 and Figure 8 , an automatic drilling structure for LED lampshade accessories, comprising a drill press 1, a U-shaped plate 2 is fixedly installed on the upper side of the tabletop of the drill press 1, the drilling structure further comprises a support unit 3 for clamping and limiting the thin-walled position of the lampshade, and a polishing unit 4 for removing burrs on the hole edge.
[0038] Referring to Figure 1 , Figure 2 and Figure 3 , the supporting unit 3 comprises two abutting cylinders 31 arranged one above the other, the abutting cylinders 31 are arranged coaxially with the drill bit of the drilling machine 1, the front and back sides of the abutting cylinders 31 are fixedly installed with support square rods 32, the two support square rods 32 at the lower part are fixedly connected with the U-shaped plate 2, and the two support square rods 32 at the upper part are slidably connected on the drilling machine 1 through a driving assembly 33.
[0039] Referring to Figure 6 , Figure 8 and Figure 9 , the polishing unit 4 comprises a moving plate 41 slidably arranged on the lower side of the horizontal section of the U-shaped plate 2, the right side of the moving plate 41 is provided with a rotating column 43 coaxially arranged with the drill bit of the drilling machine 1 through a connecting assembly 42, two symmetrical polishing pieces 44 are slidably arranged on the upper end of the rotating column 43 along the radial direction of the rotating column 43, and an executing motor 45 is fixedly installed on the moving plate 41.
[0040] When it is needed to drill the thin-walled position of the base cover, the operator first places the base cover between the two abutting cylinders 31, and makes the position to be drilled on the base cover correspond to the coaxial position of the abutting cylinders 31, and then drives the upper abutting cylinder 31 to move downward to abut on the base cover through the driving assembly 33, so that the base cover is pushed by the upper abutting cylinder 31 to abut on the lower abutting cylinder 31, thereby clamping and limiting the base cover through the two abutting cylinders 31.
[0041] Then, the drilling machine 1 moves the drill bit thereon to perform the drilling operation on the thin-walled position of the base cover, when the drill bit cuts into the thin-walled position of the base cover, the thin-walled position of the base cover is upwardly supported by the lower abutting cylinder 31 to prevent the thin-walled position of the base cover from being deformed when the drill bit cuts in, when the drilling is completed and the drill bit is withdrawn, the thin-walled position of the base cover is downwardly supported by the upper abutting cylinder 31 to prevent the hole rim from being deformed upwardly due to the frictional force between the hole rim and the drill bit when the drill bit moves upward, thereby effectively solving the problem of increased burrs due to deformation.
[0042] Then, the moving plate 41 is moved upward, the rotating column 43 is inserted into the drilled hole through the connecting assembly 42, then the polishing pieces 44 automatically extend outward along the radial direction of the rotating column 43 to abut on the hole rim, and then the rotating column 43 is rotated to drive the polishing pieces 44 to polish the hole rim, thereby further removing the burrs on the hole rim and ensuring the smoothness of the hole rim.
[0043] In order to enable the operator to more quickly and simply accurately correspond the position to be drilled on the base cover to the coaxial position of the abutting cylinder 31, the present application is designed as follows: referring to Figure 2 andFigure 3 The right side of the horizontal section of the U-shaped plate 2 is slidably provided with a limiting strip 21, a threaded adjusting screw 22 is rotatably arranged on the U-shaped plate 2 and is in threaded connection with the limiting strip 21, and a transversely arranged blocking screw 23 is in threaded connection with the right side of the horizontal section of the U-shaped plate 2.
[0044] When it is necessary to punch a thin-walled position of the base cover, an operator manually rotates the adjusting screw 22 and the blocking screw 23 in advance, so that the adjusting screw 22 drives the limiting strip 21 to move to a specified position, and at the same time, the right end surface of the blocking screw 23 is away from the horizontal section of the U-shaped plate 2 by a specified length.
[0045] When the operator places the thin-walled base cover between the two abutting cylinders 31, the thin-walled base cover is only needed to abut against the lower abutting cylinder 31, the rear inner wall of the base cover abuts against the limiting strip 21, and the bottom wall of the base cover (at this time, located on the right side) abuts against the right end surface of the blocking screw 23, so that the position to be drilled on the base cover corresponds to the coaxial position of the abutting cylinder 31, and the operator can conveniently manually feed the base cover.
[0046] Referring to Figure 2 The driving assembly 33 comprises a cantilever frame 331 fixedly installed on the drilling machine 1, a linkage plate 332 fixedly installed between the two upper support square rods 32, and a first hydraulic cylinder 333 fixedly installed on the cantilever frame 331 and fixedly connected with the linkage plate 332.
[0047] When the operator places the base cover at a specified position between the two abutting cylinders 31, the telescopic section of the first hydraulic cylinder 333 is extended, so that the first hydraulic cylinder 333 drives the linkage plate 332 to move downward, and the linkage plate 332 drives the upper abutting cylinder 31 to abut against the thin-walled base cover through the two support square rods 32 at the corresponding positions, so that the abutting cylinder 31 clamps and limits the thin-walled base cover.
[0048] In order to prevent the drill bit or the polishing piece 44 from scratching the hole rim and causing new burrs, it is necessary to clean the burrs and debris on the hole rim in time during drilling and polishing, and therefore, the present application is designed as follows: referring to Figure 2 、 Figure 3 and Figure 4 A pump air cylinder 24 is fixedly installed on the upper side of the horizontal section of the U-shaped plate 2, air guide channels 25 are formed in the interiors of the abutting cylinders 31 and the support square rods 32, the air guide channel 25 inlets on the support square rods 32 are in communication with the inner upper end region of the pump air cylinder 24 through a hose, the air guide channel 25 in the interior of the support square rod 32 is in a straight hole shape, and the air guide channel 25 in the interior of the abutting cylinder 31 is in a spiral groove shape.
[0049] When the drill bit or the polishing piece 44 drills the hole edge, the pump cylinder 24 pumps high-speed airflow into the air guide 25 inside the support square rod 32 through the hose, and the high-speed airflow flows along the air guide 25 inside the support square rod 32 to the air guide 25 inside the abutting cylinder 31, so that the high-speed airflow spirally moves along the air guide 25 inside the abutting cylinder 31, and then the high-speed airflow inside the two abutting cylinders 31 can blow the floating burrs or cuttings away from the hole edge, thereby preventing the burrs or cuttings from scratching the hole edge and causing new burrs to be generated, and the spiral groove-shaped air guide 25 in the upper abutting cylinder 31 can also cooperate with the spiral chip removal groove on the drill bit, thereby assisting the cuttings to be discharged along the spiral chip removal groove on the drill bit more quickly and completely.
[0050] In order to improve the blowing effect of the high-speed airflow on the floating burrs or cuttings, the present application introduces pulse airflow into the air guide 25 to periodically impact and disturb the floating burrs or cuttings on the hole edge, thereby improving the blowing effect on the floating burrs or cuttings, and the specific structure is as follows: refer to Figure 5 、 Figure 6 and Figure 7 , the reciprocating threaded cylinder 241 is rotationally arranged inside the pump cylinder 24 and is connected with the output shaft of the execution motor 45 in an up-down sliding manner, the partition plate 242 is fixedly installed on the inner side of the pump cylinder 24 and separates the inside of the pump cylinder 24 into two regions, the push plate 243 is arranged on the lower region of the pump cylinder 24 in an up-down sliding manner and is threadedly connected with the reciprocating threaded cylinder 241, the one-way valve 244 is connected with the push plate 243, and the opening and closing assembly 245 is arranged on the partition plate 242 and the push plate 243.
[0051] Continuing to refer to Figure 5 、 Figure 6 and Figure 7 , the opening and closing assembly 245 includes a plurality of rectangular slots penetrating the partition plate 242 in an up-down direction, the air blocking piece 246 is arranged on the lower side of the partition plate 242 in a radial sliding manner corresponding to the positions of the rectangular slots, the push spring is arranged between the air blocking piece 246 and the partition plate 242, the lower part of the air blocking piece 246 is in a wedge-shaped structure, the push frame 247 is fixedly installed on the upper side of the push plate 243 and corresponds to the air blocking piece 246 in a one-to-one manner, and the air inlet is arranged on the lower side of the pump cylinder 24 and communicates the inside and outside of the pump cylinder 24.
[0052] When the drill bit or the polishing piece 44 drills the hole edge, the execution motor 45 is started, so that the execution motor 45 drives the reciprocating threaded cylinder 241 to synchronously rotate, the reciprocating threaded cylinder 241 drives the push plate 243 to reciprocally move in the pump cylinder 24 in an up-down direction, when the push plate 243 moves upward, the push plate 243 compresses the air between the push plate 243 and the partition plate 242, and at this time, the one-way valve 244 is in a closed state.
[0053] Meanwhile, the pushing plate 243 drives the pushing frame 247 on it to move upward synchronously until the pushing frame 247 is in contact with the wedge surface of the wedge-shaped structure of the lower part of the air blocking member 246, so that the pushing frame 247 pushes the air blocking member 246 inward along the radial direction of the pumping cylinder 24 and compresses the pushing spring, so that the air blocking member 246 no longer blocks the rectangular groove, and then the high-pressure air between the pushing plate 243 and the partition plate 242 flows rapidly through the air guide 25 to the inside of the cylinder 31, thereby impacting and blowing the burrs and cuttings on the hole edge.
[0054] Then the reciprocating threaded cylinder 241 drives the pushing plate 243 to move downward, and the pushing spring pushes the air blocking member 246 to block the rectangular groove again through its elastic force. During the downward movement of the pushing plate 243, the air flow moves to the area between the pushing plate 243 and the partition plate 242 through the one-way valve 244, thereby preparing for the next compression pumping.
[0055] Referring to Figure 8 and Figure 9 , the connecting assembly 42 comprises a lower support 421 fixedly installed on the right side of the moving plate 41, and an upper support 422 vertically and slidably arranged on the upper side of the lower support 421, and the upper support 422 is rotationally connected with the rotating column 43.
[0056] Referring to Figure 8 , Figure 9 and Figure 10 , the side of the polishing member 44 away from the axis of the rotating column 43 is in V-shaped structure, so as to simultaneously polish the upper and lower edges of the hole, and the side of the polishing member 44 close to the axis of the rotating column 43 is in wedge-shaped structure, and the wedge-shaped structures of the two polishing members 44 are staggered in the front and rear directions, and a driving rod 431 is slidably arranged on the inner side of the rotating column 43 at the same axis position, and the upper end of the driving rod 431 is slidably connected with the wedge-shaped structures of the two polishing members 44 at the same time.
[0057] Referring to Figure 3 , Figure 8 and Figure 9 , the lower end of the driving rod 431 is rotationally connected with the lower support 421, and a spiral spring is arranged between the upper support 422 and the lower support 421, and the horizontal section of the U-shaped plate 2 is fixedly installed with a stop plate 423 for blocking the upper support 422 on the right side.
[0058] Referring to Figure 2 , Figure 6 and Figure 8 , a belt wheel 432 is fixedly installed on the outer side of the driving rod 431, a belt is commonly wound between the output shaft of the driving motor 45 and the belt wheel 432, and a No. 2 hydraulic cylinder 433 fixedly connected with the moving plate 41 is fixedly installed on the table of the drilling machine 1.
[0059] When the motor 45 starts to rotate, the motor 45 drives the driving rod 431 to rotate synchronously through the belt wheel 432, the driving rod 431 drives the rotating column 43 and the polishing piece 44 to rotate synchronously, when the drill bit is completed and the drill bit moves up, the telescopic section of the No. 2 hydraulic cylinder 433 is extended, so that the No. 2 hydraulic cylinder 433 drives the moving plate 41 to move up, the moving plate 41 drives the lower support 421 to move up synchronously, and the lower support 421 drives the upper support 422 to move up synchronously through the spiral spring.
[0060] Until the upper support 422 abuts against the lower side of the stop plate 423, at this time, the upper support 422 drives the polishing piece 44 to the position corresponding to the hole edge through the rotating column 43, then the lower support 421 is continuously moved up, so that the lower support 421 drives the driving rod 431 to move up relative to the rotating column 43, thereby the driving rod 431 simultaneously drives the two polishing pieces 44 to move outward along the radial direction, so that the V-shaped structure of the two polishing pieces 44 abuts against the two edges of the hole, and the polishing piece 44 grinds and removes the burrs on the hole edge.
[0061] It should be noted that the present application can protect the belt on the belt wheel 432 by installing a protective cover on the upper side of the moving plate 41, to prevent burrs or cuttings from being stuck on the belt wheel 432 and affecting the transmission, and the protective cover is a common technical means for those skilled in the art, which will not be described herein, and can be protected at a proper position according to actual conditions.
