Description

Technical Field

[0001] This invention relates to the field of high-frequency brazing technology, and in particular to a multifunctional composite drill bit automatic welding equipment. Background Technology

[0002] In the production process of carbide drill bits, the welding quality between the carbide teeth and the drill bit body directly determines the service life and cutting performance of the drill bit. Currently, the industry generally adopts high-frequency welding technology to achieve a firm connection between the two, and the corresponding automatic welding equipment has become the core equipment for large-scale production. The core welding process of the existing multi-functional composite drill bit automatic welding equipment is as follows: the carbide teeth are grasped by a robotic arm and precisely pressed onto the corresponding tooth seat of the fixed drill bit body. Then, welding wire is placed in the gap between the carbide teeth and the drill bit body. Finally, the welding area is heated by a high-frequency heating device to melt the welding wire and fill the gap, thus completing the welding operation between the carbide teeth and the drill bit body.

[0003] However, existing equipment suffers from two major drawbacks in actual use, severely impacting equipment stability, welding quality, and environmental performance. Specifically: First, high-frequency welding generates a large amount of high-temperature fumes, which must be filtered by a purification device before being discharged to meet environmental requirements and workshop safety. However, most current automatic welding equipment only has simple gas collection hoods and conveying pipes, without any pre-treatment to cool the high-temperature fumes. Due to the high temperature of the welding fumes, they directly affect the filter media in the purification device, leading to problems such as high-temperature aging, burning, and deformation. This not only drastically reduces the filtration efficiency of the filter media, making it unable to effectively purify the fumes, but also significantly shortens the lifespan of the filter media and purification device, increasing equipment maintenance costs. Second, existing equipment does not preheat the welding wire before welding. During high-frequency welding, the high-frequency coil needs to output a large amount of heat to heat the room-temperature welding wire to its melting temperature before completing the welding operation. This not only prolongs the heating time for each welding operation, reducing production efficiency, but also increases the equipment's energy consumption. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above and / or existing multifunctional composite drill bit automatic welding equipment, the present invention is proposed.

This ensures that the flue gas in the coil can be continuously and effectively cooled, thereby preventing the filter media from aging, burning, or deforming due to high temperatures, thus improving the filtration efficiency of the filter media and ensuring that the flue gas can be effectively purified, meeting environmental protection requirements and workshop operation safety. This extends the service life of the filter media and purifier, reduces the frequency of filter media replacement and equipment maintenance costs, and solves the pain points of poor environmental performance and high maintenance costs of existing equipment; at the same time, through the heat-conducting pipe and the flue gas treatment system... The integrated design utilizes the residual heat of high-temperature flue gas to preheat the welding wire in the wire feeder. Combined with the connection design of the first and second flexible hoses, it ensures smooth flow of high-temperature flue gas through the heat-conducting pipe, fully utilizing the residual heat of the flue gas. This reduces the additional heat output of the high-frequency heating device, shortens the heating time for a single welding operation, and thus improves welding efficiency and reduces equipment energy consumption. Furthermore, the design of the collection component and guide sleeve filters moisture and impurities from the surface of the welding wire before preheating, preventing impurities from entering the welding area and affecting welding quality. The kinetic energy of the rotating drill bit generates a backflow airflow, achieving automatic backflow cleaning of the guide sleeve and collection shell, preventing impurities from accumulating and clogging the guide sleeve. This ensures smooth wire feeding, continuous impurity cleaning, and adapts to the needs of large-scale continuous processing, improving the stability of welding quality. Attached Figure Description

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, referring to Figures 1-8 This is the first embodiment of the present invention, which provides a multifunctional composite automatic drill bit welding device, including a welding machine 1, an operating table 12 fixedly connected to the bottom of the welding machine 1, a clamping member 13 disposed on the top of the operating table 12, an equipment cabinet 2 fixedly connected to one side of the welding machine 1, a purifier 21 fixedly connected to the bottom of the inner cavity of the equipment cabinet 2, a negative pressure interface 22 disposed on one side of the purifier 21, a coil 23 connected to one side of the negative pressure interface 22, a cold water pan 24 covering the surface of the coil 23, and a wind-driven component 25 disposed on one side of the cold water pan 24 for rapidly cooling the coolant in the cold water pan 24. A negative pressure hood 26 is provided on one side of the drive unit 25, and an adjustable lifting frame 27 is fixedly connected to its surface and fixedly connected to the top of the inner cavity of the equipment cabinet 2. The wire feeder 3 is provided on one side of the operating table 12, and a collection cabinet 31 is fixedly connected to its bottom. The heat conduction pipe 32 is fixedly connected to the inner cavity of the wire feeder 3 for preheating the welding wire in the wire feeder 3. A frame 33 is fixedly connected to one side of the wire feeder 3, and a welding wire spool 34 is rotatably connected to the inner cavity of the frame 33. A guide sleeve 35 is provided on one side of the welding wire spool 34, and one side of the guide sleeve 35 penetrates through the wire feeder 3 and extends into the wire feeder 3. A collection unit 36 ​​covers the surface of the guide sleeve 35.

[0032] Welding machine 1 is the core welding component of the equipment, providing the core heating power for high-frequency brazing of carbide teeth and drill bit base, ensuring the smooth progress of welding operations; operating table 12 provides a stable operating platform for welding operations, and at the same time provides an installation carrier for clamping component 13, ensuring that the drill bit is accurately positioned and firmly fixed during the welding process; clamping component 13 is used to fix the drill bit base, preventing the drill bit from shifting during the welding process, ensuring the accuracy of the welding position, and improving the welding quality.

[0033] Equipment cabinet 2 provides installation space for flue gas treatment components, enabling integrated layout of flue gas treatment modules and saving workshop space. Purifier 21 is the core component of flue gas purification, used to filter harmful fumes generated during welding, meeting environmental protection requirements and workshop safety. Negative pressure interface 22 provides negative pressure for flue gas collection, ensuring that high-temperature fumes can be smoothly drawn into the treatment system. Coil 23 is used to transport high-temperature fumes and, in conjunction with cooling water pan 24, achieves initial cooling of the fumes, preventing high-temperature fumes from directly entering purifier 21 and causing damage. The filter media; the coolant in the cold water pan 24 wraps around the coil 23, pre-treating the high-temperature flue gas in the coil 23 to cool it down and extend the service life of the filter media in the purifier 21; the wind-driven component 25 uses the kinetic energy of the flue gas flow to quickly cool the coolant in the cold water pan 24, realizing the adaptive circulation of the cooling system and ensuring the stability of the cooling effect; the negative pressure hood 26 is used to collect the high-temperature flue gas generated in the welding area, and the adjustable lifting frame 27 can adjust the height of the negative pressure hood 26 according to the drill bit size and welding position to improve the flue gas collection efficiency.

[0034] The wire feeder 3 is responsible for feeding welding wire to the welding area, providing consumable support for the welding operation. The drive source of the wire feeder 3 is located outside the machine, which avoids the impact of the high temperature of the flue gas preheating on the drive source. The collection cabinet 31 is used to collect impurities on the surface of the welding wire and waste generated during the cleaning process, keeping the equipment clean. The heat pipe 32 uses the residual heat of the high temperature flue gas to preheat the welding wire in the wire feeder 3, solving the problems of no welding wire preheating, low welding efficiency, and high energy consumption in existing equipment. The frame 33 provides installation support for the welding wire reel 34, ensuring the stability of the welding wire feeding process. The welding wire reel 34 is used to store the welding wire, realizing a continuous supply of welding wire. The guide sleeve 35 guides the welding wire, assists in the welding wire feeding, and filters impurities on the surface of the welding wire. The collection component 36 is covered on the surface of the guide sleeve 35 to collect the welding wire impurities filtered by the guide sleeve 35, preventing impurities from entering the welding area and affecting the welding quality, while preventing impurities from accumulating and clogging the guide sleeve 35, ensuring smooth welding wire feeding.

[0035] It should be noted that the working principles of welding machine 1, purifier 21, adjustable lifting frame 27 and wire feeder 3 are all existing technologies, which can be clearly understood by those skilled in the art, and will not be elaborated here.

[0036] Example 2, refer to Figures 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the wind-driven component 25 includes a first hose 251 connected to the bottom of the negative pressure hood 26. One side of the first hose 251 passes through the wire feeder 3 and is connected to the heat-conducting pipe 32. The side of the heat-conducting pipe 32 away from the first hose 251 is connected to a second hose 252. One side of the second hose 252 is connected to a housing 253. One side of the housing 253 passes through the cold water pan 24 and is connected to the coil 23.

[0038] The first flexible hose 251 serves as a flue gas transport channel, introducing the high-temperature flue gas collected by the negative pressure hood 26 into the heat-conducting pipe 32 inside the wire feeder 3, maximizing the utilization of the flue gas waste heat. The heat-conducting pipe 32 is connected to the first flexible hose 251 and the second flexible hose 252, forming a complete flue gas transport circuit, which not only achieves wire preheating but also ensures that the flue gas can smoothly enter the subsequent cooling and purification stage. The second flexible hose 252 transports the heat-exchanged flue gas from the heat-conducting pipe 32 to the housing 253, providing power for the rotation of the impeller 254. The housing 253 provides installation space for the impeller 254 and also serves as a transition structure for the flue gas to enter the coil 23, ensuring smooth flue gas transport. The housing 253 is connected to the cold water pan 24 and the coil 23, allowing the flue gas passing through the impeller 254 to smoothly enter the coil 23 for subsequent cooling and purification.

[0039] Specifically, an impeller 254 is rotatably connected to the inner cavity of the housing 253. A synchronous shaft 255 is fixedly connected to one side of the impeller 254. A drive blade 256 is fixedly connected to one side of the synchronous shaft 255. An airflow channel 257 is provided on the surface of the drive blade 256 and is fixedly connected to the cold water pan 24. An air inlet is provided on one side of the airflow channel 257 and the other side of the airflow channel 257 is open.

[0040] Impeller 254 is located inside housing 253. When flue gas passes through housing 253, it drives impeller 254 to rotate, converting the kinetic energy of flue gas into the mechanical kinetic energy of impeller 254. Synchronous shaft 255 connects impeller 254 and drive blade 256, transmitting the rotation of impeller 254 to drive blade 256, thus achieving synchronous power transmission. When drive blade 256 rotates, it generates airflow in airflow channel 257. As the airflow passes through airflow channel 257, it carries away the heat transferred by heat-conducting copper sheet 258, thereby cooling the coolant. Airflow channel 257 provides installation space for drive blade 256 and guides airflow to ensure that the airflow can act on heat-conducting copper sheet 258, improving heat dissipation efficiency. An air inlet on one side of airflow channel 257 is used to introduce outside cold air, and the other side is open to discharge the dissipated hot air, forming a complete heat dissipation airflow circuit.

[0041] Specifically, a heat-conducting copper sheet 258 is fixedly connected to the inner cavity of the cold water pan 24. One side of the heat-conducting copper sheet 258 penetrates the cold water pan 24 and extends into the airflow channel 257.

[0042] The heat-conducting copper sheet 258 is fixedly connected to the inner cavity of the cold water pan 24. Copper has excellent thermal conductivity and can quickly absorb the heat from the flue gas absorbed by the coolant. One side of the heat-conducting copper sheet 258 extends into the airflow channel 257, so that heat can be directly transferred to the airflow in the airflow channel 257, maximizing the heat dissipation efficiency and preventing heat from accumulating in the cold water pan 24, which would cause the coolant to heat up, thus achieving adaptive circulation cooling.

[0043] Specifically, the collection component 36 includes a collection shell 361 covering the surface of the guide sleeve 35. The bottom of the collection shell 361 penetrates the frame 33 and extends into the collection cabinet 31. A tapered groove 362 is provided on one side of the guide sleeve 35. An exhaust chamber 363 is provided in the inner cavity of the guide sleeve 35 and communicates with the tapered groove 362. A backflush pipe 364 is connected to one side of the exhaust chamber 363 and communicates with the airflow channel 257. A first one-way valve 365 is fixedly connected to the surface of the backflush pipe 364.

[0044] A collection shell 361 is fitted over the surface of the guide sleeve 35 to collect welding wire impurities filtered down by the guide sleeve 35 and guide the impurities into the collection cabinet 31 for centralized treatment. A conical groove 362 on one side of the guide sleeve 35 facilitates the sliding of impurities into the collection shell 361, preventing impurities from accumulating on the surface of the guide sleeve 35. An exhaust chamber 363 is connected to the conical groove 362, providing a channel for backflushing airflow. A backflushing pipe 364 connects the exhaust chamber 363 and the airflow channel 257, introducing the airflow in the airflow channel 257 into the exhaust chamber 363 to achieve backflushing cleaning of the guide sleeve 35 and the collection shell 361. A first one-way valve 365 is fixed to the surface of the backflushing pipe 364. When the airbag 3616 does not expand and block the airflow channel 257, it can prevent airflow from entering the backflushing pipe 364, thereby prioritizing heat dissipation for the heat-conducting copper sheet 258.

[0045] Specifically, the inner cavity of the operating table 12 is fixedly connected to a mounting base 366, the inner cavity of the mounting base 366 is rotatably connected to a reciprocating screw 367, the surface of the reciprocating screw 367 is provided with a moving block 368, the bottom of the moving block 368 is fixedly connected to a moving cylinder 369, both sides of the moving cylinder 369 are slidably connected to fixed cylinders 3610 and fixedly connected to the mounting base 366, the bottom of the fixed cylinder 3610 is connected to an exhaust pipe 3611, the surface of the exhaust pipe 3611 is fixedly connected to a second one-way valve 3612, the corresponding side of the fixed cylinder 3610 is connected to an air inlet pipe 3613, and the surface of the air inlet pipe 3613 is fixedly connected to a third one-way valve 3614.

[0046] Mounting base 366 provides a mounting carrier for components such as reciprocating screw 367, ensuring structural stability. When reciprocating screw 367 rotates, it drives moving block 368 to move back and forth, thereby driving moving cylinder 369 to slide within fixed cylinder 3610. Moving cylinder 369 and fixed cylinder 3610 cooperate to form a cylinder-like structure. When moving cylinder 369 slides, it changes the air pressure within fixed cylinder 3610, realizing the intake and exhaust of gas. Exhaust pipe 3611 is used to exhaust compressed gas within fixed cylinder 3610. Second one-way valve 3612 controls the gas flow direction of exhaust pipe 3611, ensuring that gas can only be exhausted. Intake pipe 3613 is used to draw in outside air to replenish the gas within fixed cylinder 3610. Third one-way valve 3614 controls the gas flow direction of intake pipe 3613, ensuring that gas can only be drawn in.

[0047] Specifically, a three-way valve 3615 is connected to one side of the exhaust pipe 3611, and one side of the three-way valve 3615 passes through the airflow channel 257 and is connected to the airbag 3616. A one-way pipe 3617 is fixedly connected to the top of the airbag 3616.

[0048] The three-way valve 3615 connects the exhaust pipe 3611 and the airbag 3616, and is used to control the flow direction of compressed gas, guiding the compressed gas discharged from the exhaust pipe 3611 into the airbag 3616. The airbag 3616 is used to store gas. When the airbag 3616 expands, it will block the airflow channel 257, causing the air pressure in the airflow channel 257 to rise, thereby pushing the airflow through the backflushing pipe 364 for backflushing and cleaning. The one-way pipe 3617 is fixed to the top of the airbag 3616 and is used to slowly release the gas in the airbag 3616, causing the airbag 3616 to gradually contract, restoring the unobstructed flow of the airflow channel 257, and ensuring that the coolant can continue to dissipate heat. Thus, the expansion and contraction of the airbag 3616 realizes the automatic switching between backflushing and heat dissipation.

[0049] Specifically, the surface of the airbag 3616 is fixedly connected to the bracket 3618, and is fixedly connected to the inner cavity of the airflow channel 257.

[0050] The bracket 3618 is fixedly connected to the inner cavity of the airflow channel 257 and also fixedly connected to the airbag 3616, providing stable support for the airbag 3616. This ensures that when the airbag 3616 inflates, it can block the airflow channel 257, allowing the airflow to smoothly enter the backflow tube 364. When it deflates and contracts, it can return to its initial position without affecting the airflow within the airflow channel 257.

[0051] Specifically, the clamping member 13 includes a motor 131 fixedly connected to the bottom of the inner cavity of the operating table 12. The output shaft of the motor 131 is fixedly connected to a rotating shaft 132. A pneumatic chuck 133 is fixedly connected to the top of the rotating shaft 132. The top of the pneumatic chuck 133 passes through the operating table 12 and is rotatably connected to the operating table 12.

[0052] The motor 131 provides power to the clamping component 13, driving the rotating shaft 132 to rotate. The rotating shaft 132 connects the motor 131 to the pneumatic chuck 133, transmitting the power of the motor 131 to the pneumatic chuck 133. The pneumatic chuck 133 is used to fix the drill bit base, and the drill bit is quickly clamped and released through pneumatic control, which is convenient to operate and firmly fixed. The pneumatic chuck 133 passes through the operating table 12 and is rotatably connected to it, ensuring that the pneumatic chuck 133 can rotate stably and drive the drill bit to switch welding positions.

[0053] Specifically, a sector gear set 134 is provided on one side of the rotating shaft 132, and a connecting shaft 135 is meshed with the surface of the rotating shaft 132 through the sector gear set 134. One side of the connecting shaft 135 passes through the mounting base 366 and is fixedly connected to the reciprocating lead screw 367.

[0054] The sector gear set 134 meshes with the surface of the rotating shaft 132 to change the direction of rotation and adapt to the installation direction of the reciprocating screw 367; the connecting shaft 135 connects the sector gear set 134 and the reciprocating screw 367, transmits the rotation of the rotating shaft 132 to the reciprocating screw 367, so that the reciprocating screw 367 rotates synchronously, thereby driving the moving block 368 to move back and forth, generating a backflow airflow.

[0055] Working principle: The operator first places the drill bit base on the top of the pneumatic chuck 133 of the clamping component 13, and uses pneumatic control to clamp the drill bit base, thus fixing the drill bit. Then, the welding machine 1, the purifier 21 and the wire feeder 3 are turned on to start the high-frequency brazing operation. The robotic arm grabs the carbide teeth and presses them precisely onto the corresponding tooth seats on the drill bit base. At the same time, the wire feeder 3 starts to feed the welding wire. After the welding wire is taken out from the welding wire spool 34, it is guided into the wire feeder 3 through the guide sleeve 35 on the frame 33. Finally, it is fed to the gap between the carbide teeth and the drill bit base in the welding area. The high-frequency heating device of the welding machine 1 heats the welding area, causing the welding wire to melt and fill the gap, thus completing the welding of a set of carbide teeth.

[0056] The high-temperature fumes generated during welding are subjected to negative pressure suction through the negative pressure interface 22 under the action of the purifier 21. The negative pressure hood 26 (adjusted to a suitable height by the adjustable lifting frame 27) collects the high-temperature fumes. The collected high-temperature fumes enter the heat-conducting pipe 32 in the wire feeder 3 through the first hose 251. The residual heat of the fumes is used to preheat the welding wire in the heat-conducting pipe 32, solving the problems of no preheating of welding wire, low welding efficiency and high energy consumption in the background technology.

[0057] The flue gas after preheating the welding wire enters the housing 253 through the second hose 252. After passing through the housing 253, the flue gas then enters the coil 23. Under the action of the coolant in the cold water pan 24, the flue gas is cooled down. The cooled flue gas enters the purifier 21 through the negative pressure interface 22. After being filtered and purified by the purifier 21, it is discharged, avoiding direct damage to the filter material by the high-temperature flue gas and solving the problems of easy aging of filter material and high maintenance cost in the background technology.

[0058] When the flue gas passes through the casing 253, it drives the impeller 254 to rotate. The impeller 254 drives the drive blades 256 to rotate through the synchronous shaft 255. The drive blades 256 generate airflow in the airflow channel 257. The airflow draws in outside cold air through the air inlet on one side of the airflow channel 257. At the same time, the heat-conducting copper fins 258 in the cooling water pan 24 conduct the heat absorbed by the flue gas by the coolant to the airflow channel 257, where it is carried away by the airflow generated by the drive blades 256, achieving rapid cooling of the coolant and ensuring stable cooling effect.

[0059] When the welding wire passes through the guide sleeve 35, the moisture and impurities adhering to its surface are filtered by the guide sleeve 35. The impurities slide down through the conical groove 362 on one side of the guide sleeve 35 to the collection shell 361, and then are guided into the collection cabinet 31 by the collection shell 361 to achieve centralized collection of impurities. After a set of carbide teeth is welded, the motor 131 starts and drives the rotating shaft 132 to rotate. The rotating shaft 132 drives the pneumatic chuck 133 and the drill bit body to rotate synchronously, so that the drill bit switches to the welding position of the next set of carbide teeth and waits for the next welding. At the same time, the rotating shaft 132 drives the connecting shaft 135 to rotate through the sector gear set 134. The connecting shaft 135 drives the reciprocating screw 367 to rotate. The reciprocating screw 367 drives the moving block 368 to move back and forth. The moving block 368 drives the moving cylinder 369 to slide alternately in the two sets of fixed cylinders 3610.

[0060] When the movable cylinder 369 slides into one of the fixed cylinders 3610, the air pressure inside that fixed cylinder 3610 increases, the second one-way valve 3612 opens, and compressed gas enters the airbag 3616 through the exhaust pipe 3611 and the three-way valve 3615, causing the airbag 3616 to inflate and block the airflow channel 257. At this time, the air pressure inside the other fixed cylinder 3610 decreases, the third one-way valve 3614 opens, and outside air is drawn in through the air inlet pipe 3613 to replenish the air pressure. After the airbag 3616 inflates, the air pressure inside the airflow channel 257 increases, and the airflow overcomes the resistance of the first one-way valve 365, allowing air to pass through... The gas enters the exhaust chamber 363 through the backflushing pipe 364, and then blows back towards the collection shell 361 through the conical groove 362, blowing the accumulated impurities into the collection cabinet 31 to prevent the collection shell 361 from becoming blocked. At the same time, the one-way pipe 3617 at the top of the airbag 3616 slowly releases the gas inside the airbag 3616, the airbag 3616 gradually contracts, the airflow channel 257 is restored to unobstructed, the first one-way valve 365 closes the backflushing pipe 364, and the airflow generated by the driving blade 256 continues to dissipate heat on the heat-conducting copper plate 258, realizing the continuous cooling of the coolant. Thus, the backflushing cleaning and coolant cooling are alternately carried out.

[0062] Specifically, the top and bottom of the cold water pan 24 are equipped with add pipes and drain pipes, respectively.

[0063] During use, the top of the cold water pan 24 is equipped with an add pipe for convenient replenishment of coolant, and the bottom is equipped with an drain pipe for periodically draining aging coolant and sediment impurities, facilitating equipment maintenance.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
