[0002] Pliers are hand tools used for clamping and securing workpieces or twisting, bending, and cutting metal wires. Pliers are V-shaped and typically consist of three parts: a handle, jaws, and a mouth. The mouth is usually made of carbon structural steel. During machining, holes are drilled in the mouth to facilitate the attachment of the handle to the mouth, and then hollow rivets are used to connect the handle to the mouth. When drilling holes in the mouth, the mouth needs to be placed into the clamping cavity, with one end protruding and aligned with the drilling bit. Each time the mouth is clamped and secured, manual alignment is required, necessitating repeated adjustments to ensure the mouth is aligned with the drill bit, making the operation tedious. Furthermore, when the drill bit drills into the mouth, the resulting debris accumulates on the mouth surface, making it difficult to clean and affecting the drilling quality. Utility Model Content

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] This utility model provides a pliers hole-making device. This pliers hole-making device can quickly align the hole-making end of the pliers jaws with the hole-making drill bit through a positioning component, solving the problem of repeatedly adjusting the pliers jaws when manually comparing and clamping them. It can position the hole-making end of the pliers jaws, making the operation simple, time-saving and labor-saving. Furthermore, the cleaning component can quickly blow the generated airflow towards the hole-making drill bit, blowing away the debris generated during drilling around the drill bit, keeping the hole-making area of ​​the pliers jaws clean and avoiding affecting the drilling quality.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0025] like Figures 1-6 As shown, a pliers hole-making device includes a hole-making box 1, a workbench 101 installed inside the hole-making box 1, hole-making drill bits 102 disposed on both sides of the top of the workbench 101, a positioning component disposed on the top of the workbench 101, the positioning component including: a pad 3, a positioning block 303 and a scale layer 303, and a cleaning component disposed on the outside of the hole-making drill bits 102, the cleaning component including: an equipment box 7, an air pump 701, an air pipe 703 and an air nozzle 704.

[0026] The workbench 101 has clamping blocks 103 installed on both sides of the top. The clamping blocks 103 have clamping cavities 104 inside. Each clamping block 103 has a clamping cylinder 105 installed on the top. The bottom of the clamping cylinder 105 is connected to a telescopic rod 106. The clamping cavity 104 has a pressure block 107 inside. Each clamping block 103 has a through hole 108 on the top. The telescopic rod 106 passes through the through hole 108 and is connected to the clamping block 103.

[0027] When drilling holes in the jaws of the pliers, the jaws are placed inside the bottom of the clamping cavity 104, with the drilling end of the jaws protruding outside the clamping cavity 104. Then, the clamping cylinder 105 is activated to drive the telescopic rod 106 to move inside the through hole 108, causing the telescopic rod 106 to push the clamping block 103 downward to clamp and fix the jaws, ensuring that the jaws are stable and do not loosen when drilling holes. After drilling is completed, the clamping cylinder 105 is activated to drive the telescopic rod 106 to retract, causing the clamping block 103 to move upward and be removed from the jaws to release the fixation.

[0028] The workbench 101 has two pads 3 installed on its top. Each pad 3 has a positioning block 303 fixed on its top by bolts. Both sides of the top of the two pads 3 are provided with scale layers 303. A connecting plate 301 is installed between the two pads 3. The positioning block 303 is located between the two scale layers 303.

[0029] When the drilling end of the jaw protrudes outside the clamping cavity 104, its protruding end rests on the pad 3, and the pad 3 is equipped with a positioning block 303. The protruding end of the jaw can be directly pressed against the outer end of the positioning block 303 to align with the drilling drill bit 102. Then, the other end of the jaw is clamped and fixed inside the clamping cavity 104. This allows for quick alignment and placement of the drilling end of the jaw with the drilling drill bit 102, solving the problem of repeated adjustments to the jaw required for manual comparison and clamping. The drilling end of the jaw can be positioned and placed, making the operation simple, time-saving, and labor-saving. Since the positioning block 303 is located between two scale layers 303, the movement distance of the positioning block 303 can be known through the scale layers 303, thereby quickly adjusting the alignment position of the positioning block 303 and the drilling drill bit 102. Then, the positioning block 303 is installed and fixed on the pad 3 with bolts.

[0030] Servo motors 2 are installed on both sides of the top of the hole-making box 1. A drive gear 201 is connected to the top of the servo motor 2 via a motor shaft. A fixed rod cylinder 202 is installed on one side of the servo motor 2 and extends through the inside of the hole-making box 1. A rotating shaft 203 is rotatably connected inside the fixed rod cylinder 202 via a bearing. A transmission gear 204 that meshes with the drive gear 201 is installed on the top of the rotating shaft 203, and the bottom of the rotating shaft 203 is connected to the hole-making drill bit 102.

[0031] After aligning and fixing the hole-making end of the jaws with the hole-making drill bit 102, start the servo motor 2 to drive the motor shaft to rotate the drive gear 201. Since the drive gear 201 is meshed with the transmission gear 204, the drive gear 201 will drive the transmission gear 204 and the rotating shaft 203 to rotate. The bottom of the rotating shaft 203 is connected to the hole-making drill bit 102. That is, the rotating shaft 203 drives the hole-making drill bit 102 to rotate quickly on the jaws to make holes. During the rotation of the rotating shaft 203, since the rotating shaft 203 is rotatably connected to the inside of the fixed rod cylinder 202 through the bearing, it can ensure the normal operation of the rotating shaft 203 and also place the rotating shaft 203 stably for use.

[0032] The hole-making box 1 has positioning rods 4 installed on its four sides, and the worktable 101 has slide cylinders 401 installed on its four sides that are slidably connected to the positioning rods 4. The bottom of the hole-making box 1 has a stepper motor 5 installed inside, and the top of the stepper motor 5 is connected to a threaded screw 501. The top of the worktable 101 has a screw hole 6 that is threadedly connected to the threaded screw 501.

[0033] When drilling a hole at the end of the jaw, the stepper motor 5 is started to drive the threaded screw 501 to rotate. The worktable 101 rotates through the threaded hole 6, so that when the threaded screw 501 rotates, it can drive the worktable 101 to move up and down. When the worktable 101 moves upward, it can drive the jaw to move to the bottom end of the drilling bit 102 and contact it, ensuring that the drilling bit 102 can drill the jaw. After drilling, the threaded screw 501 drives the worktable 101 to move downward, so that the jaw is removed from the bottom end of the drilling bit 102, which is convenient for disassembling and replacing the jaw. During the up and down movement of the worktable 101, the worktable 101 is slidably connected to the positioning rod 4 through the slide cylinder 401, which can ensure the stable operation of the worktable 101.

[0034] The pad block 3 has multiple protective holes 304 on its top, and the workbench 101 has chip removal holes that are aligned with the multiple protective holes 304 on its top. When the drilling bit 102 drills through the pliers, the protective holes 304 are larger than the diameter of the drilling bit 102. The protective holes 304 can prevent the drilling bit 102 from hitting the pad block 3, thus preventing damage to the drilling bit 102. Furthermore, the debris that falls into the protective holes 304 can be discharged from the workbench 101 through the chip removal holes, making it easy to clean and preventing blockage of the protective holes 304.

[0035] Among them, equipment boxes 7 are installed on both sides of the outer end of the hole-making box 1. An air pump 701 is installed at the bottom of the equipment box 7. An air pipe 703 is connected to the exhaust port of the air pump 701. An air nozzle 704 is installed at one end of the air pipe 703. An air inlet pipe 702 is connected to the air inlet of the air pump 701. The air inlet pipe 702 passes through the bottom of the equipment box 7. The pipe body of the air pipe 703 passes through the inside of the hole-making box 1. The air nozzle 704 faces the hole-making drill bit 102.

[0036] When the drilling bit 102 drills holes in the jaws, a large amount of debris will accumulate around it. At this time, the air pump 701 is started. The air pump 701 draws air from the air inlet pipe 702 to the outside of the equipment box 7. The negative pressure generated inside the air pump 701 is blown out from the exhaust port and discharged into the air blowing pipe 703. The air is then transported to the air nozzle 704 through the air blowing pipe 703 to form an airflow that blows out quickly. Since the air nozzle 704 is set towards the drilling bit 102, it can blow away the debris generated around the drilling bit 102, keeping the jaw drilling area clean and avoiding affecting the drilling quality of the jaws.

[0037] The control panel is fixedly installed on one side of the outer end of the hole-making box 1. Multiple control buttons are installed on the outside of the control panel, and a power cord is installed on the back of the control panel. The clamping cylinder 105, servo motor 2, stepper motor 5, and air pump 701 are connected to the control panel via wires. The power cord is 3 meters long, and a plug is installed at the other end of the power cord. The plug can be inserted into an indoor socket to connect the power supply, so that the control panel, clamping cylinder 105, servo motor 2, stepper motor 5, and air pump 701 can be powered on and used normally. The control panel can control the clamping cylinder 105, servo motor 2, stepper motor 5, and air pump 701 to start and stop. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.
