Description

Technical Field

[0001] The present invention relates to the technical field of tapping equipment, and specifically relates to a tapping equipment for processing a TV backplane. Background Art

[0002] With the popularization and development of LCD TVs, the structural processing requirements of TV backplanes are becoming increasingly precise. The processing process of TV backplanes mainly includes injection molding process and tapping process. Among them, the tapping process is to tap holes so that the TV backplane can be screwed with screws, which requires the use of tapping equipment.

[0003] Using a drilling and tapping machine or a bench tapping machine can improve the accuracy (error ±0.1 mm), but it takes a long time to change the model (the fixture adjustment takes more than 30 minutes), it cannot adapt to backplanes of multiple sizes (such as different hole layouts for 32-85 inch TVs), and it lacks an automatic chip removal function, and metal chips are likely to cause equipment jams. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A tapping equipment for processing a TV backplane, including a bottom plate support. The top of the bottom plate support is fixedly connected with a bottom plate. One side of the top of the bottom plate is fixedly connected with a support arm. The side of the support arm is fixedly connected with a tapping device. The top of the bottom plate is fixedly connected with a fixing device, and the fixing device is arranged below the tapping device;

[0005] The tapping device includes a tapping chassis. A straight chute is formed at the top of the tapping chassis. A tapping component is slidably connected to the inner side surface of the straight chute. A limiting component is slidably connected to the top of the tapping chassis. The movable end of a first telescopic rod is fixedly connected to the side of the tapping component. The fixed end of the first telescopic rod is fixedly connected to a fixed block. The bottom of the fixed block is fixedly connected to a cooling component. The movable end of a hydraulic telescopic rod is fixedly connected to the top of the tapping chassis. The limiting component is sleeved on the movable end of the hydraulic telescopic rod and is rotatably connected to the movable end of the hydraulic telescopic rod. The fixed end of the hydraulic telescopic rod is fixedly connected to the side of a support arm. The top of the fixed block is fixedly connected to the bottom of the tapping chassis. The movable end of the hydraulic telescopic rod drives the tapping chassis to move. The movement of the tapping chassis drives the first sliding bar to move. The movement of the first sliding bar drives the sliding block to move. The sliding block drives the lower limiting disc to move. The movement of the lower limiting disc drives the first motor to move. The downward movement of the first motor drives the tapered tapping tool to move downward. The drive shaft of the first motor drives the tapered tapping tool to rotate, thereby completing the tapping operation on the back panel. The tapered design of the tapered tapping tool is beneficial for compensation after multiple tapping wears. By adjusting the corresponding components of the limiting component, different descending amounts of the hydraulic telescopic rod are achieved, so that tapping is performed at different positions of the tapered tapping tool. Thus, even after the tapered tapping tool is worn, tapping can still be performed without replacing the drill bit, avoiding the tapping error problem caused by drill bit wear after continuous processing, reducing the processing error while reducing the number of drill bit replacements, and thereby improving the production efficiency.

[0006] Preferably, the tapping component includes a first motor. The drive shaft of the first motor is fixedly connected to a tapered tapping tool. A connecting block is fixedly connected to the side of the first motor. A lower limiting disc is fixedly connected to the top of the first motor. A sliding block is fixedly connected to the top of the lower limiting disc. A first sliding bar is fixedly connected to the side of the sliding block. An upper positioning disc is fixedly connected to the top of the sliding block. The side of the connecting block is fixedly connected to the movable end of the first telescopic rod. The first sliding bar is slidably connected to the inner wall of the straight chute. The bottom of the upper positioning disc contacts the top of the limiting component. The top of the lower limiting disc contacts the bottom of the tapping chassis.

[0007] Preferably, the limiting component includes a limiting disc. An arc chute is formed at the top of the limiting disc. A first fixed block is rotatably connected to the top of the limiting disc through a rotating shaft. The fixed end of an electric telescopic rod is fixedly connected to the side of the first fixed block. The movable end of the electric telescopic rod is fixedly connected to a second fixed block. A limiting rod is fixedly connected to the top of the limiting disc. A limiting nut is rotationally connected to the top of the limiting rod through a thread. A limiting ring is sleeved on and slidably connected to the side of the limiting rod.

[0008] Preferably, the second fixing block is rotatably connected to the top of the tapping chassis through a rotating shaft. The inner wall of the limiting ring is fixedly connected to the side surface of the hydraulic telescopic rod. The bottom of the upper positioning disk contacts the top of the limiting disk. The side surface of the upper positioning disk is slidably connected to the inner wall of the arc-shaped chute. When it is necessary to adjust the position between the tapping holes, the movable end of the electric telescopic rod reciprocates. The electric telescopic rod expands and contracts to change the distance between the first fixing block and the second fixing block. The distance between the first fixing block and the second fixing block changes. The second fixing block drives the limiting disk to rotate. The rotation of the limiting disk drives the upper positioning disk to move along the inner wall of the arc-shaped chute. The movement of the upper positioning disk drives the sliding block to move. The sliding block moves along the straight chute, so that the first motor approaches or moves away from the hydraulic telescopic rod, thereby changing the distance between multiple drill bits, so as to meet different processing requirements. After the tapping drill bits are worn out multiple times, rotate the limiting nut to change the position of the limiting nut on the limiting rod, thereby changing the height of the limiting nut from the limiting disk. When the hydraulic telescopic rod drives the limiting disk to descend, the limiting nut drives the limiting rod to stop moving. The limiting rod drives the limiting disk to stop moving. The limiting disk drives the upper positioning disk to stop moving, thereby limiting the depth of the tapered tapping tool, so as to prevent over-processing. At the same time, by simple adjustment, a high-precision transmission device is not required to control the tool compensation, thereby reducing the operation difficulty. The change of the tapping position is realized, and at the same time, the tapping depth is changed, so as to perform wear compensation and adjustment of the tapping position.

[0009] Preferably, the cooling assembly includes a wind box housing. The side surface of the inner wall of the wind box housing is fixedly connected with an electric fan. The side of the wind box housing is communicated with a duct. The fixed end of the second telescopic rod is fixedly connected to the top of the inner wall of the wind box housing. The movable end of the second telescopic rod is fixedly connected with a rubber pad. The top of the wind box housing is fixedly connected to the bottom of the fixing block. When performing tapping operations, the descent of the tapping chassis drives the fixing block to descend. The movement of the fixing block drives the second telescopic rod to descend. The second telescopic rod drives the rubber pad to press on the surface of the back plate, thereby fixing the back plate, so as to keep stable during tapping. Start the electric fan. The electric fan drives air to enter the interior of the wind box housing and is discharged through the duct. The duct is arranged near the tapered tapping tool, so as to clean the debris generated by tapping, blow the metal debris into the interior of the fixing device for collection. At the same time, the air performs air cooling on the tapered tapping tool, so as to cool the tapping part, so as to prevent the deformation of the tapping part caused by heat, so as to ensure the quality of tapping.

[0010] Preferably, the fixing device includes a fixing base plate. A first material leakage hole is formed in the top of the fixing base plate. A second material leakage hole is fixedly connected to the side surface of the fixing base plate. An arc-shaped wind baffle is fixedly connected to the top of the second material leakage hole. A fixing component is fixedly connected to the part of the fixing base plate on one side of the second material leakage hole. An inclined guide plate is fixedly connected to the inner side surface of the fixing base plate. A collecting component is fixedly connected to the side surface of the fixing base plate. The bottom of the fixing base plate is fixedly connected to the top of the base plate.

[0011] Preferably, the fixing component includes a fixing strip. A sliding hole is formed in the side surface of the fixing strip. A sliding shaft is slidably connected to the inner wall of the sliding hole. A rack is fixedly connected to the top of the fixing strip. A moving housing is fixedly connected to the side surface of the sliding shaft. An arc-shaped guide plate is fixedly connected to the side surface of the moving housing. A fixing frame is fixedly connected to the side surface of the arc-shaped guide plate. A limiting plate is fixedly connected to the side surface of the fixing frame. A spring piece is fixedly connected to the bottom of the limiting plate. The bottom of the spring piece contacts the top of the moving housing. The side of the fixing strip away from the fixing frame is fixedly connected to the side surface of the fixing base plate. Before the back plate is placed, manually rotate to drive the fixing frame to rotate. The rotation of the fixing frame drives the arc-shaped guide plate to rotate. The rotation of the arc-shaped guide plate drives the moving housing to rotate. The moving housing rotates along the axis of the sliding shaft, thereby lifting the moving housing, and dragging the moving housing to move according to the actual size. When the moving housing moves to a suitable position, put down the moving housing. A rack adapted to the rack is fixedly connected to the inner top wall of the moving housing, so that the moving housing is fixed when it moves to a suitable position. When the back plate is inserted between the spring piece and the moving housing, the back plate is fixed by the elastic force of the spring piece, so as to keep the back plate stable during tapping. The arc-shaped guide plate on the side of the arc-shaped guide plate guides the back plate during placement, so as to align the position more quickly for rapid clamping. It realizes the stable tapping of the back plate while realizing rapid loading and unloading. The area above the first material leakage hole is the tapping range. The metal chips generated during the tapping process fall under the action of gravity and move along the inclined guide plate, so as to enter the inside of the collecting component for collection. The arc-shaped wind baffle is used to guide the air flow to prevent the metal chips from flying randomly under the action of the air flow, realizing the collection of the metal chips.

[0012] Preferably, the collecting component includes a collecting housing. An arc-shaped guide housing is fixedly connected to the top of the collecting housing. A collecting box is slidably connected to the inner side surface of the collecting housing. A debris leakage net is fixedly connected to the bottom of the collecting box. A collecting box handle is fixedly connected to the side surface of the collecting box.

[0013] Preferably, the side surface of the arc-shaped guide shell is communicated with the side surface of the fixed bottom plate, and the top of the collection outer shell is fixedly connected to the bottom side surface of the inclined guide plate. Metal debris is filtered by the debris leakage net and remains inside the collection box, thereby collecting the metal debris. Air directly flows from the bottom of the debris leakage net, thereby guiding the airflow and completing the collection of the metal debris.

[0014] The present invention provides a tapping device for processing a TV backplane, which has the following beneficial effects:

[0015] 1. In the tapping device for processing the TV backplane, the movable end of the hydraulic telescopic rod drives the tapping chassis to move. The movement of the tapping chassis drives the first slide bar to move. The movement of the first slide bar drives the sliding block to move. The sliding block drives the lower limit disk to move. The movement of the lower limit disk drives the first motor to move. The downward movement of the first motor drives the conical tapping tool to move downward. The drive shaft of the first motor drives the conical tapping tool to rotate, thereby completing the tapping operation on the backplane. The conical design of the conical tapping tool is beneficial for compensation after multiple tapping wears. By adjusting the corresponding components of the limit assembly, the hydraulic telescopic rod has different descending amounts, so that the conical tapping tool taps at different positions. Therefore, after the conical tapping tool is worn, it is still possible to perform the tapping operation without replacing the drill bit, thereby avoiding the tapping error problem caused by the wear of the drill bit after continuous processing, reducing the processing error and reducing the number of times of replacing the drill bit, thereby improving the production efficiency.

[0016] 2. In the tapping device for processing the TV backplane, when it is necessary to adjust the position between the tapping holes, the movable end of the electric telescopic rod performs a reciprocating motion. The electric telescopic rod expands and contracts to change the distance between the first fixed block and the second fixed block. The change in the distance between the first fixed block and the second fixed block causes the second fixed block to drive the limit disk to rotate. The rotation of the limit disk drives the upper positioning disk to move along the inner wall of the arc-shaped chute. The movement of the upper positioning disk drives the sliding block to move. The sliding block moves along the straight chute, so that the first motor approaches or moves away from the hydraulic telescopic rod, thereby changing the distance between multiple drill bits to meet different processing requirements. After the drill bits are worn after multiple tappings, rotate the limit nut to change the position of the limit nut on the limit rod, thereby changing the height of the limit nut from the limit disk. When the hydraulic telescopic rod drives the limit disk to descend, the limit nut drives the limit rod to stop moving. The limit rod drives the limit disk to stop moving. The limit disk drives the upper positioning disk to stop moving, thereby limiting the depth of the conical tapping tool and preventing over-processing. At the same time, through simple adjustment, a high-precision transmission device is not required for control during tool compensation, thereby reducing the operation difficulty. The change of the tapping position is realized, and at the same time, the tapping depth is changed, so as to perform wear compensation and adjustment of the tapping position.

[0017] 3. The tapping device for processing the back panel of the TV set is configured such that during the tapping operation, the tapping chassis descends to drive the fixing block to descend. The movement of the fixing block drives the second telescopic rod to descend, and the second telescopic rod drives the rubber pad to press on the surface of the back panel, thereby fixing the back panel, so as to maintain stability during tapping. Start the electric fan, which drives air to enter the interior of the air box housing and be discharged through the air duct. The air duct is arranged near the conical tapping tool, thereby cleaning the debris generated during tapping, blowing the metal debris into the interior of the fixing device for collection. At the same time, the air performs air cooling on the conical tapping tool, thereby cooling the tapping part, so as to prevent deformation of the tapping part caused by heat, and thus ensure the quality of tapping.

[0018] 4. The tapping device for processing the back panel of the TV set is configured such that before the back panel is placed, manually rotate to drive the fixing frame to rotate. The rotation of the fixing frame drives the arc-shaped guide plate to rotate. The rotation of the arc-shaped guide plate drives the moving housing to rotate. The moving housing rotates along the axis of the sliding shaft, thereby lifting the moving housing, and dragging the moving housing to move according to the actual size. When the moving housing moves to the appropriate position, lower the moving housing. The top inner wall of the moving housing is fixedly connected with a rack adapted to the rack, so that the moving housing is fixed when it moves to the appropriate position. When the back panel is inserted between the spring piece and the moving housing, the back panel is fixed by the elastic force of the spring piece, so as to keep the back panel stable during tapping. The arc-shaped guide plate on the side of the arc-shaped guide plate guides the back panel during placement, so as to align the position more quickly for rapid clamping. It realizes the stable tapping of the back panel while achieving rapid loading and unloading. Above the first material leakage hole is the tapping range. The metal debris generated during the tapping process falls under the action of gravity and moves along the inclined guide plate, thereby entering the interior of the collection assembly for collection. The arc-shaped wind baffle is used to guide the airflow to prevent the metal debris from flying randomly under the action of the airflow, realizing the collection of the metal debris.

[0019] 5. The tapping device for processing the back panel of the TV set is configured such that the metal debris is left inside the collection box through the filtering action of the debris leakage net, thereby collecting the metal debris. The air directly flows from the bottom of the debris leakage net, thereby guiding the airflow and completing the collection of the metal debris. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer toFigures 1 - 3 , the present invention provides a technical solution: a tapping device for processing a TV backplane, including a bottom plate bracket 1. The top of the bottom plate bracket 1 is fixedly connected with a bottom plate 2. One side of the top of the bottom plate 2 is fixedly connected with a support arm 3. The side of the support arm 3 is fixedly connected with a tapping device 4. The top of the bottom plate 2 is fixedly connected with a fixing device 5. The fixing device 5 is arranged below the tapping device 4.

[0031] The fixing device 5 fixes the backplane and simultaneously collects metal waste chips. The tapping device 4 performs tapping operations on the bottom plate and can adjust the size. At the same time, it compensates for the wear of the tool bit after multiple processes, increasing the processing amount of a single drill bit, thereby reducing the number of drill bit replacements. At the same time, it collects and cleans the debris after tapping, and cools the tapping part, thereby ensuring the tapping quality and preventing heat generated during tapping from causing thermal deformation.

[0032] The tapping device 4 includes a tapping chassis 401. The top of the tapping chassis 401 is provided with a straight chute 402. The inner side surface of the straight chute 402 is slidably connected with a tapping assembly 403. The top of the tapping chassis 401 is slidably connected with a limiting assembly 404. The side of the tapping assembly 403 is fixedly connected with the movable end of a first telescopic rod 405. The fixed end of the first telescopic rod 405 is fixedly connected with a fixed block 406. The bottom of the fixed block 406 is fixedly connected with a cooling assembly 407. The top of the tapping chassis 401 is fixedly connected with the movable end of a hydraulic telescopic rod 408. The limiting assembly 404 is sleeved on the movable end of the hydraulic telescopic rod 408 and is rotatably connected with the movable end of the hydraulic telescopic rod 408. The fixed end of the hydraulic telescopic rod 408 is fixedly connected with the side of the support arm 3. The top of the fixed block 406 is fixedly connected with the bottom of the tapping chassis 401.

[0033] The tapping assembly 403 includes a first motor 4031. The drive shaft of the first motor 4031 is fixedly connected with a conical tapping tool 4032. The side of the first motor 4031 is fixedly connected with a connecting block 4033. The top of the first motor 4031 is fixedly connected with a lower limit disk 4034. The top of the lower limit disk 4034 is fixedly connected with a sliding block 4035. The side of the sliding block 4035 is fixedly connected with a first sliding strip 4036. The top of the sliding block 4035 is fixedly connected with an upper positioning disk 4037. The side of the connecting block 4033 is fixedly connected with the movable end of the first telescopic rod 405. The first sliding strip 4036 is slidably connected with the inner wall of the straight chute 402. The bottom of the upper positioning disk 4037 contacts the top of the limiting assembly 404. The top of the lower limit disk 4034 contacts the bottom of the tapping chassis 401.

[0034] After the backplane is fixed under the fixing action of the fixing device 5, the fixing device 5 fixes the backplane. The movable end of the hydraulic telescopic rod 408 drives the tapping chassis 401 to move. The movement of the tapping chassis 401 drives the movement of the first slide bar 4036. The movement of the first slide bar 4036 drives the movement of the sliding block 4035. The sliding block 4035 drives the lower limit disk 4034 to move. The movement of the lower limit disk 4034 drives the first motor 4031 to move. The downward movement of the first motor 4031 drives the tapered tapping tool 4032 to move downward. The drive shaft of the first motor 4031 drives the tapered tapping tool 4032 to rotate, thus completing the tapping operation on the backplane. The tapered design of the tapered tapping tool 4032 is beneficial for compensation after multiple tapping wear. By adjusting the components corresponding to the limit component 404, the hydraulic telescopic rod 408 performs different descending amounts, so that tapping is performed at different positions of the tapered tapping tool 4032. Thus, after the tapered tapping tool 4032 is worn, tapping can still be performed without replacing the drill bit, thereby avoiding the tapping error problem caused by drill bit wear after continuous processing, reducing the processing error and the number of times of replacing the drill bit, and thus improving the production efficiency.

[0035] Please refer to Figures 1 - 5 , the present invention provides a technical solution: The limit component 404 includes a limit disk 4041. An arc-shaped chute 4042 is opened at the top of the limit disk 4041. The top of the limit disk 4041 is rotatably connected to a first fixing block 4043 through a rotating shaft. The side of the first fixing block 4043 is fixedly connected to the fixed end of an electric telescopic rod 4044. The movable end of the electric telescopic rod 4044 is fixedly connected to a second fixing block 4045. The top of the limit disk 4041 is fixedly connected to a limit rod 4046. The top of the limit rod 4046 is rotationally connected with a limit nut 4047 through a thread. A limit ring 4048 is sleeved and slidably connected to the side of the limit rod 4046. The second fixing block 4045 is rotatably connected to the top of the tapping chassis 401 through a rotating shaft. The inner wall of the limit ring 4048 is fixedly connected to the side of the hydraulic telescopic rod 408. The bottom of the upper positioning disk 4037 contacts the top of the limit disk 4041. The side of the upper positioning disk 4037 is slidably connected to the inner wall of the arc-shaped chute 4042.

[0036] When adjusting the position between the tapping holes that need to be processed, the movable end of the electric telescopic rod 4044 moves reciprocally. The electric telescopic rod 4044 expands and contracts to change the distance between the first fixed block 4043 and the second fixed block 4045. When the distance between the first fixed block 4043 and the second fixed block 4045 changes, the second fixed block 4045 drives the limit disc 4041 to rotate. The rotation of the limit disc 4041 drives the upper positioning disc 4037 to move along the inner wall of the arc-shaped chute 4042. The movement of the upper positioning disc 4037 drives the sliding block 4035 to move. The sliding block 4035 moves along the straight chute 402, so that the first motor 4031 approaches or moves away from the hydraulic telescopic rod 408, thereby changing the distance between multiple drill bits, so as to meet different processing requirements. After the tapping drill bits are worn out after multiple operations, rotate the limit nut 4047 to change the position of the limit nut 4047 on the limit rod 4046, thereby changing the height of the limit nut 4047 from the limit disc 4041. When the hydraulic telescopic rod 408 drives the limit disc 4041 to descend, the limit nut 4047 drives the limit rod 4046 to stop moving. The limit rod 4046 drives the limit disc 4041 to stop moving. The limit disc 4041 drives the upper positioning disc 4037 to stop moving, so as to limit the depth of the tapered tapping tool 4032, thereby preventing over-processing. At the same time, through simple adjustment, there is no need for a high-precision transmission device to control during tool compensation, thereby reducing the operation difficulty. The change of the tapping position is realized, and at the same time, the tapping depth is changed, so as to perform wear compensation and adjustment of the tapping position.

[0037] The cooling assembly 407 includes a bellows housing 4071. A side wall of the inner wall of the bellows housing 4071 is fixedly connected with an electric fan 4072. A side of the bellows housing 4071 is communicated with an air duct 4073. A fixed end of a second telescopic rod 4074 is fixedly connected to the top of the inner wall of the bellows housing 4071. A movable end of the second telescopic rod 4074 is fixedly connected with a rubber pad 4075. The top of the bellows housing 4071 is fixedly connected to the bottom of the fixed block 406.

[0038] During the tapping operation, the tapping chassis 401 descends to drive the fixed block 406 to descend. The movement of the fixed block 406 drives the second telescopic rod 4074 to descend. The second telescopic rod 4074 drives the rubber pad 4075 to press on the surface of the back plate, thereby fixing the back plate, so as to maintain stability during tapping. The electric fan 4072 is started. The electric fan 4072 drives air to enter the inside of the air box housing 4071 and is discharged through the air duct 4073. The air duct 4073 is arranged near the conical tapping tool 4032, thereby cleaning the debris generated during tapping, blowing the metal debris into the inside of the fixing device 5 for collection. At the same time, the air performs an air-cooling operation on the conical tapping tool 4032, thereby cooling the tapping part, so as to prevent deformation of the tapping part caused by heat, and thus ensure the quality of tapping.

[0039] Please refer to Figures 1 - 7 , the present invention provides a technical solution: The fixing device 5 includes a fixing bottom plate 501. A first material leakage hole 502 is opened at the top of the fixing bottom plate 501. The side of the fixing bottom plate 501 is fixedly connected with a second material leakage hole 503. The top of the second material leakage hole 503 is fixedly connected with an arc-shaped wind baffle 504. The part of the fixing bottom plate 501 on one side of the second material leakage hole 503 is fixedly connected with a fixing component 505. The side wall of the inner part of the fixing bottom plate 501 is fixedly connected with an inclined guide plate 506. The side of the fixing bottom plate 501 is fixedly connected with a collection component 507. The bottom of the fixing bottom plate 501 is fixedly connected with the top of the bottom plate 2.

[0040] The fixing component 505 includes a fixing strip 5051. A sliding hole 5052 is opened on the side of the fixing strip 5051. A sliding shaft 5053 is slidably connected to the inner wall of the sliding hole 5052. The top of the fixing strip 5051 is fixedly connected with a rack 5054. The side of the sliding shaft 5053 is fixedly connected with a moving housing 5055. The side of the moving housing 5055 is fixedly connected with an arc-shaped guide plate 5056. The side of the arc-shaped guide plate 5056 is fixedly connected with a fixing frame 5057. The side of the fixing frame 5057 is fixedly connected with a limiting plate 5058. The bottom of the limiting plate 5058 is fixedly connected with a spring piece 5059. The bottom of the spring piece 5059 contacts the top of the moving housing 5055. The side of the fixing strip 5051 away from the fixing frame 5057 is fixedly connected with the side of the fixing bottom plate 501.

[0041] Before inserting the backplane, manually rotate to drive the fixing frame 5057 to rotate. The rotation of the fixing frame 5057 drives the arc-shaped guide plate 5056 to rotate. The rotation of the arc-shaped guide plate 5056 drives the moving housing 5055 to rotate. The moving housing 5055 rotates along the axis of the sliding shaft 5053, thereby lifting the moving housing 5055, and dragging the moving housing 5055 to move according to the actual size. When the moving housing 5055 moves to the appropriate position, lower the moving housing 5055. The top of the inner wall of the moving housing 5055 is fixedly connected with a rack adapted to the rack 5054, so that the moving housing 5055 is fixed when it moves to the appropriate position. When the backplane is inserted between the spring piece 5059 and the moving housing 5055, the backplane is fixed by the elastic force of the spring piece 5059, so as to keep the backplane stable during tapping. The arc-shaped guide plate on the side of the arc-shaped guide plate 5056 guides the backplane during placement, so as to align the position more quickly for rapid clamping. It realizes the rapid loading and unloading of the backplane while keeping it stable during tapping. Above the first material leakage hole 502 is the tapping range. The metal chips generated during the tapping process fall under the action of gravity and move along the inclined guide plate 506, and then enter the inside of the collection assembly 507 for collection. The arc-shaped wind shield 504 is used to guide the airflow to prevent the metal chips from flying randomly under the action of the airflow, realizing the collection of the metal chips.

[0042] Please refer to Figures 1 - 8 , the present invention provides a technical solution: the collection assembly 507 includes a collection outer shell 5071, the top of the collection outer shell 5071 is fixedly connected with an arc-shaped guide shell 5072, the side wall of the inner wall of the collection outer shell 5071 is slidably connected with a collection box 5073, the bottom of the collection box 5073 is fixedly connected with a debris leakage net 5074, the side of the collection box 5073 is fixedly connected with a collection box handle 5075, the side of the arc-shaped guide shell 5072 is communicated with the side of the fixed bottom plate 501, and the top of the collection outer shell 5071 is fixedly connected with the bottom side of the inclined guide plate 506.

[0043] The metal chips are left inside the collection box 5073 through the filtering action of the debris leakage net 5074, thereby collecting the metal chips. The air directly flows from the bottom of the debris leakage net 5074, thereby guiding the airflow and completing the collection of the metal chips.

[0044] Working principle: After the backplane is fixed under the fixing action of the fixing device 5, the fixing device 5 fixes the backplane. The movable end of the hydraulic telescopic rod 408 drives the tapping chassis 401 to move. The movement of the tapping chassis 401 drives the movement of the first slide bar 4036. The movement of the first slide bar 4036 drives the movement of the sliding block 4035. The sliding block 4035 drives the lower limit disk 4034 to move. The movement of the lower limit disk 4034 drives the movement of the first motor 4031. The downward movement of the first motor 4031 drives the downward movement of the conical tapping tool 4032. The drive shaft of the first motor 4031 drives the conical tapping tool 4032 to rotate, thus completing the tapping operation on the backplane. The conical design of the conical tapping tool 4032 is beneficial for compensation after multiple tapping wears. By adjusting the corresponding components of the limit assembly 404, the hydraulic telescopic rod 408 performs different amounts of descent, so that tapping is performed at different positions of the conical tapping tool 4032. When adjusting the position between the tapping holes, the movable end of the electric telescopic rod 4044 performs reciprocating motion. The telescopic movement of the electric telescopic rod 4044 changes the distance between the first fixing block 4043 and the second fixing block 4045. The change in the distance between the first fixing block 4043 and the second fixing block 4045 causes the second fixing block 4045 to drive the limit disk 4041 to rotate. The rotation of the limit disk 4041 drives the upper positioning disk 4037 to move along the inner wall of the arc-shaped chute 4042. The movement of the upper positioning disk 4037 drives the movement of the sliding block 4035. The sliding block 4035 moves along the straight chute 402, so that the first motor 4031 approaches or moves away from the hydraulic telescopic rod 408, thus changing the distance between multiple drill bits to meet different processing requirements. After the multiple tapping drill bits are worn, rotate the limit nut 4047 to change the position of the limit nut 4047 on the limit rod 4046, thus changing the height of the limit nut 4047 from the limit disk 4041. When the hydraulic telescopic rod 408 drives the limit disk 4041 to descend, the limit nut 4047 drives the limit rod 4046 to stop moving. The limit rod 4046 drives the limit disk 4041 to stop moving. The limit disk 4041 drives the upper positioning disk 4037 to stop moving, thus limiting the depth of the conical tapping tool 4032. When performing the tapping operation, the tapping chassis 401 descends to drive the fixing block 406 to descend. The movement of the fixing block 406 drives the second telescopic rod 4074 to descend. The second telescopic rod 4074 drives the rubber pad 4075 to press on the surface of the backplane, thus fixing the backplane and keeping it stable during tapping. Start the electric fan 4072. The electric fan 4072 drives air to enter the interior of the air box housing 4071 and be discharged through the air duct 4073. The air duct 4073 is arranged near the conical tapping tool 4032, thus cleaning the chips generated during tapping and blowing the metal chips into the interior of the fixing device 5 for collection. At the same time, the air performs air cooling on the conical tapping tool 4032. Before the backplane is placed,Manually rotate to drive the fixed frame 5057 to rotate. The rotation of the fixed frame 5057 drives the arc-shaped guide plate 5056 to rotate. The rotation of the arc-shaped guide plate 5056 drives the moving housing 5055 to rotate. The moving housing 5055 rotates along the axis of the sliding shaft 5053, thereby lifting the moving housing 5055 and dragging the moving housing 5055 to move according to the actual size. When the moving housing 5055 moves to a suitable position, lower the moving housing 5055. A rack adapted to the rack 5054 is fixedly connected to the top of the inner wall of the moving housing 5055, so that the moving housing 5055 is fixed when it moves to a suitable position. When the back plate is inserted between the spring piece 5059 and the moving housing 5055, the back plate is fixed by the elastic force of the spring piece 5059. Metal debris is left inside the collection box 5073 through the filtering action of the debris screen 5074, thereby collecting the metal debris. Air directly flows from the bottom of the debris screen 5074, thereby guiding the air flow and completing the collection of metal debris.
