Implementation Method

[0033] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0034] Example 1: An automatic hole punching device for a sound box, such as Figure 1-Figure 5As shown, it includes a drilling table 1, a movable plate 101, a drilling machine 102, an electric push rod 103, a material ejecting rod 104, a lower arc block 105, a clamping table 106, a material clamping connecting plate 107, a connecting plate tension spring 108, a support plate 109, an upper arc block 110, a clamping bracket 111, a material pressing plate 112, a rubber head 113, a torsion spring 114, an eccentric plate 115, a top plate 116 and a material bearing mechanism. The drilling table 1 is symmetrically provided with two, and the movable plate 101 is slidably connected to the drilling table 1, and the movable plate 101 is fixed on the A drilling machine 102 is installed, and a drill bit for drilling is installed on the drilling machine 102. The drilling machine 102 is a prior art. An electric push rod 103 is fixedly installed on the lower side of the drilling table 1. The telescopic axis of the electric push rod 103 is fixedly connected to the lower side of the movable plate 101. Two top material connecting rods 104 are symmetrically fixed on the movable plate 101. A lower arc block 105 is fixedly connected to the end of the top material connecting rod 104 away from the movable plate 101. A clamping table 106 is fixedly provided in the middle of the two drilling tables 1. The sliding plates 106 are symmetrically symmetrical in the vertical direction. There are two clamping plates 107 that are dynamically connected. The clamping plates 107 are both covered with plate tension springs 108. The two ends of the plate tension springs 108 are respectively connected to the clamping plates 107 and the clamping platform 106. The side of the clamping plates 107 that are close to each other is fixed with a support plate 109. The two support plates 109 are symmetrically fixed with two upper arc blocks 110 on the side that are away from each other. The upper arc block 110 cooperates with the lower arc block 105. The top of the support plate 109 is symmetrically fixed with two clamping brackets 111. The clamping bracket 111 is rotatably connected. It is connected to a pressing plate 112, on which a rubber head 113 is fixed, two torsion springs 114 are symmetrically connected between the clamping bracket 111 and the pressing plate 112, an eccentric plate 115 is fixed to the pressing plate 112, and four top plates 116 are symmetrically fixed to the clamping table 106, the top plates 116 cooperate with the eccentric plates 115, and when the support plate 109 moves downward, the top plates 116 press the wooden board through the eccentric plates 115, and a material bearing mechanism for bearing the wooden board is connected to the support plate 109.

[0035] The wooden board to be drilled is placed on the material supporting mechanism, and then the electric push rod 103 is controlled to extend to drive the movable plate 101 to move in the direction of the clamping table 106, thereby driving the drilling machine 102 and the ejecting connecting rod 104 to move in the direction close to the wooden board. At the same time, the lower arc block 105 moves away from under the upper arc block 110, and the connecting plate tension spring 108 drives the clamping connecting plate 107 and the supporting plate 109 to reset downward, thereby driving the clamping bracket 111, the pressing plate 112 and the eccentric plate 115 to move downward. The eccentric plate 115 will be blocked by the top plate 116 during its downward movement, thereby driving the pressing plate 112 to rotate, and the torsion spring 114 will store force. The rotating pressing plate 112 will drive the rubber head 113 to press tightly on the wooden board. On, the drilling machine 102 starts to drill holes at both ends of the wooden board. After the drilling is completed, the electric push rod 103 is controlled to retract, and the movable plate 101 drives the drilling machine 102 and the lifting connecting rod 104 to reset. During the resetting process of the movable plate 101, the material-bearing mechanism is controlled to cancel the support of the wooden board, so that the wooden board can fall downward to realize automatic unloading. A collection box can be placed below so that the wooden board can fall downward into the collection box for collection. When the lower arc block 105 contacts the upper arc block 110 and continues to reset, the lower arc block 105 will be lifted upward by the upper arc block 110, thereby driving the clamping plate 107 and the support plate 109 to move upward, and the pressing plate 112 rotates and resets under the action of the torsion spring 114.

[0036] like Figure 4 and Figure 6 As shown, the material receiving mechanism includes a material receiving plate 2 and a material receiving spring 201 . Two material receiving plates 2 are symmetrically slidably connected to the support plate 109 , and the material receiving plates 2 are sleeved with a material receiving spring 201 .

[0037] Place the wooden board that needs to be drilled on the four receiving plates 2. When the drilling is completed and the movable plate 101 is reset, the front and rear receiving plates 2 are moved away from each other, and the receiving spring 201 is compressed, so that the four receiving plates 2 are moved away from under the wooden board, and the wooden board can fall down to unload the material, and then the receiving spring 201 pushes the front and rear receiving plates 2 to reset in the direction of approaching each other.

[0038] Example 2: Based on Example 1, Figure 2 、 Figure 6 ,and Figure 7As shown, it also includes a discharging mechanism for automatically unloading the processed wooden boards. The discharging mechanism is connected to the support plate 109. The discharging mechanism includes a discharging connecting rod 3, a discharging pressure block 301, a discharging spring 302 and a discharging top block 303. Two discharging connecting rods 3 are symmetrically fixed to the upper end of the movable plate 101. The end of the discharging connecting rod 3 away from the movable plate 101 is slidably connected to the discharging pressure block 301 in the vertical direction. The discharging pressure block 301 is sleeved with a discharging spring 302. When the discharging pressure block 301 moves upward, the discharging spring 302 will be compressed. A discharging top block 303 is fixed to the supporting plate 2. The discharging top block 303 cooperates with the discharging pressure block 301. When the discharging pressure block 301 moves in the direction away from the clamping platform 106, the supporting plate 2 will be pushed to both sides by the discharging top block 303.

[0039] When the movable plate 101 moves in the direction of the clamping platform 106, it will drive the discharging connecting rod 3 and the discharging pressing block 301 to move synchronously. When the discharging pressing block 301 moves in the direction of the clamping platform 106, it will contact the discharging top block 303. The discharging top block 303 squeezes the discharging pressing block 301 upward through the inclined surface. When the discharging top block 303 is out of contact with the discharging pressing block 301, the discharging spring 302 pushes the discharging pressing block 301 to reset downward. When the movable plate 101 moves in the direction away from the clamping platform 106, it will also drive the discharging connecting rod 3 and the discharging pressing block 301 to move synchronously. When the discharging pressing block 301 moves in the direction away from the clamping platform 106, After the cam 310 is in contact with the push rod 303, the upper and lower arc blocks 303 are in contact with each other, and the upper and lower arc blocks 305 are in contact with each other, so that the upper and lower arc blocks 303 can be lifted up and discharged.

[0040] like Figure 1 and Figure 8As shown, it also includes a feeding mechanism for automatically feeding wooden boards, the feeding mechanism is connected to the support plate 109, the feeding mechanism includes a loading box 4, an inner convex block 401, a convex block spring 402, a clamping plate 403, an outer convex rod 404, a convex rod tension spring 405, a material blocking plate 406 and a trigger assembly, a loading box 4 is fixed above the clamping table 106, the front and rear sides of the loading box 4 are symmetrically connected to the four inner convex blocks 401 by the guide rod, and the guide rod is provided with a convex block spring 402, and the two inner convex blocks 401 on the same side are fixedly connected with a clamping plate 403, the clamping plate 403 is located on the side of the inner convex block 401 close to the loading box 4, the clamping plate 403 can enter the loading box 4 to clamp the wooden board, and the left and right sides of the loading box 4 are symmetrically connected by the guide rod The sliding connection has two outer protruding rods 404, and the guide rods are both provided with protruding rod tension springs 405. The two ends of the protruding rod tension springs 405 are respectively fixed to the outer protruding rods 404 and the loading box 4. The outer protruding rods 404 are fixed with a blocking plate 406 for blocking the wooden board from falling downwards. The outer protruding rods 404 are U-shaped, and the outer protruding rods 404 are provided with inclined surfaces at both ends close to the inner protruding block 401. When the inner protruding block 401 moves in the direction close to the loading box 4, the two outer protruding rods 404 will be squeezed in the direction away from each other. A trigger assembly is connected to the clamping plate 403. When the clamping plate 107 moves upward, the trigger assembly is used to clamp the two clamping plates 403 to clamp the upper wooden board. At the same time, the blocking plate 406 no longer blocks the lower wooden board from falling downwards, thereby realizing automatic loading of the wooden board.

[0041] The wooden boards to be processed are stacked in the loading box 4 in advance. When the support plate 109 moves upward, the trigger assembly drives the two clamping plates 403 to move into the loading box 4. The clamping plates 403 clamp the wooden boards in the loading box 4, but the lowermost wooden board is not within the clamping range of the clamping plates 403. At the same time, the clamping plates 403 squeeze the outer protruding rods 404 on both sides in the direction away from each other through the inner protrusions 401, thereby driving the blocking plate 406 to move away from the bottom of the loading box 4. The lowest wooden board can fall down onto the material receiving plate 2. When the support plate 109 moves downward, the trigger assembly no longer applies force to the clamping plate 403. The clamping plate 403 and the inner protrusion 401 move out of the loading box 4 under the action of the protrusion spring 402, thereby no longer blocking the wooden board in the loading box 4 from falling downward. At the same time, the protrusion rod tension spring 405 will drive the outer protrusion 404 and the material blocking plate 406 to reset, and the material blocking plate 406 moves to the bottom of the loading box 4 to block the wooden board from falling downward.

[0042] like Figure 3 and Figure 8As shown, the trigger assembly includes a trigger block 5 and a trigger rod 501. The trigger block 5 is fixedly connected to the side of the two clamping plates 403 that are away from each other. Two trigger rods 501 are symmetrically fixed to the two clamping plates 107. The trigger rods 501 are located on both sides of the charging box 4. The top of the trigger rod 501 is provided with a protrusion that cooperates with the trigger block 5, and the protrusion is located on the side where the two trigger rods 501 are close to each other.

[0043] When the support plate 109 moves upward or downward, it will drive the trigger rod 501 to move synchronously. When the trigger rod 501 moves upward, it will squeeze the clamping plate 403 into the loading box 4 through the trigger block 5. When the trigger rod 501 moves downward, it will break away from the trigger block 5, thereby canceling the force on the clamping plate 403.

[0044] Example 3: Based on Example 2, Figure 9 and Figure 10 As shown, it also includes a guide mechanism for facilitating the collection of wood chips. The guide mechanism is installed on the drilling table 1. The guide mechanism includes a folding assembly, a leakage barrel 6, a movable barrel 601 and a middle spring 602. The drilling table 1 is connected with a folding assembly, the leakage barrel 6 is fixedly connected to the folding assembly, and the movable barrel 601 is slidably connected to the leakage barrel 6. A through hole is opened in the middle of the movable barrel 601 for facilitating the penetration of the drill bit on the drilling machine 102. Two middle springs 602 are symmetrically sleeved on the movable barrel 601. When the support plate 109 moves downward, the leakage barrel 6 is driven by the folding assembly to move to the end of the wooden board where a hole needs to be drilled.

[0045] When the support plate 109 moves downward, it will drive the leakage barrel 6 and the movable barrel 601 to move through the folding assembly, so that the leakage barrel 6 will be attached to the position on the wooden board where a hole needs to be drilled, and the drill bit of the drilling machine 102 passes through the movable barrel 601 and the leakage barrel 6 to drill a hole in the wooden board. Since there is an opening on the lower side of the leakage barrel 6, the wood chips generated by drilling will fall downward through the opening on the lower side of the leakage barrel 6. A collection box for collecting wood chips can be placed below to achieve unified collection and processing of wood chips. The leakage barrel 6 can prevent wood chips from splashing and affecting the normal operation of the device. The movable barrel 601 and the middle spring 602 can cooperate to play a buffering and protective role to prevent the drilling machine 102 from colliding with the leakage barrel 6 and the movable barrel 601.

[0046] like Figure 9As shown, the folding assembly includes a movable frame 7, a folding tension spring 701, a folding rod 702, a folding pressure plate 703 and a guide frame 704. The movable frame 7 is connected to the drilling table 1 in a horizontal sliding direction. Two folding tension springs 701 are symmetrically sleeved on the movable frame 7. The two ends of the folding tension spring 701 are respectively connected to the movable frame 7 and the drilling table 1. The movable frame 7 is symmetrically connected to the two folding rods 702 for rotation. Two guide frames 704 are symmetrically fixed to one end of the drilling table 1 close to the clamping table 106. The guide frame 704 is connected to the folding pressure plate 703 in a vertical sliding direction. The ends of the folding rods 702 away from the movable frame 7 are both rotatably connected to the folding pressure plate 703 on the same side.

[0047] When the support plate 109 moves downward, it will drive the folding pressure plate 703 to move downward. The folding pressure plate 703 will drive the movable frame 7 to move toward the pressing table through the folding rod 702, and stretch the folding tension spring 701, so that the movable frame 7 can drive the leakage barrel 6 to stick to the two ends of the wooden board. When the support plate 109 moves upward to reset, the folding tension spring 701 drives the movable frame 7 to move away from the clamping table 106 to reset, and drives the folding pressure plate 703 to reset upward through the folding rod 702.

[0048] like Figure 3 and Figure 8 As shown, the trigger block 5 and the trigger rod 501 are both provided with an arc surface on the side close to each other.

[0049] By providing arc surfaces on the trigger block 5 and the trigger rod 501 , it is ensured that the trigger rod 501 can move the clamping plate 403 into the charging box 4 through the trigger block 5 .

[0050] like Figure 2 As shown, the folding pressing plate 703 is located below the support plate 109.

[0051] The folding pressing plate 703 is set below the support plate 109 so that the support plate 109 moves downward to drive the folding pressing plate 703. In the process of pressing the wooden board, the leakage barrel 6 can be attached to both ends of the wooden board, thereby improving processing efficiency.
