Description

Technical Field

[0001] The invention belongs to the technical field of metal tapping, and in particular relates to a tapping device for manufacturing mechanical metal parts. Background Art

[0002] A tapping device is a mechanical device used to process internal threads on materials such as metals and plastics. It cuts materials to form threads by rotating the tap. Tapping devices are widely used in the manufacturing industry. They can improve production efficiency, reduce labor costs, and ensure consistency in processing quality. The working principle of a common tapping device is to drive the spindle to rotate through an electric motor, and the tap on the spindle rotates accordingly. The workpiece is fixed on the workbench. By adjusting the position and angle of the tapping machine, the tap can accurately cut into the surface of the workpiece and cut along a predetermined trajectory. During the cutting process, cutting fluid needs to be continuously added to cool and lubricate the tap to prevent overheating and wear.

[0003] Although the existing tapping device has achieved good production and use effects, there are still some common problems when using it. Although it can realize the tapping of parts, the parts it taps are all plate-shaped or rod-shaped parts. Such parts are more convenient to fix, that is, the processing difficulty is relatively small. Therefore, the existing tapping device can effectively process such parts, but the types of parts are varied. When dealing with spherical parts, due to the unique outer surface of spherical parts, it is extremely difficult for the existing tapping device to fix them, and the fixing effect is poor, and the parts are very likely to slip. The fixing effect of the parts is a key factor that directly affects the tapping effect of the parts. If the effect is not ideal, it will not only cause the equipment to lose its processing ability and affect the processing effect of the equipment, but also affect the safety of the equipment. Therefore, a new tapping device for manufacturing mechanical metal parts that can tap spherical parts is needed to solve the problem that the existing tapping device cannot tap spherical parts.

[0009] As a preferred embodiment of the present invention, the air control component includes a mounting sleeve fixedly connected to the bottom of the mounting plate, a driving airbag is placed in the mounting sleeve, the driving airbag and the first air sleeve, as well as the driving airbag and the second air sleeve are connected via a hose, an air pump with an air intake port and an air exhaust port is fixedly connected below the mounting sleeve, the exhaust port of the air pump is connected to the driving airbag via a hose, and the air intake port of the air pump is also connected to the inside of the hollow column via a hose.

Subsequently, the tapping piece is precisely controlled by the sliding drive assembly to slowly lower the tap, and the position of the circular hole on the spherical part is adjusted to ensure alignment with the tap. After that, the tap is continued to be inserted until its tip is slightly embedded in the circular hole, so as to accurately set the tapping position and preliminarily stabilize the spherical part. Next, the air control assembly is started, which extracts the air in the hollow column and uses the negative pressure formed to simultaneously activate the clamping assembly and the pressing assembly. The clamping assembly acts on the spherical part from the side and the pressing assembly from the top to achieve a stable clamping. It is worth noting that the rubber pad equipped on the top of the hollow column forms a seal after the spherical part is placed. As the air is extracted, the adsorption force of the hollow column on the spherical part gradually increases, providing a preliminary fixation before the clamping and pressing actions to prevent the part from shifting or falling. When the air is extracted to a certain extent, the adsorption force of the hollow column reaches the maximum, and the clamping and pressing assemblies work together to achieve a comprehensive fixation of the spherical part. At this time, the pressing component not only applies pressure, but also increases the compression of the spherical part on the rubber pad, effectively preventing air leakage. After the fixation is completed, the tapping part drives the tap to rotate and descend to complete the tapping operation. After the operation is completed, the tap is reset, and the air control component operates in reverse to inject air into the hollow column to reset the clamping and pressing components and release the adsorption of the spherical part. The part can then be easily removed for the next operation. This setting cleverly utilizes the adsorption force of the hollow column, combined with the multi-directional clamping and pressing mechanism, to achieve rapid and effective fixation of the spherical part, ensuring the stability and efficiency of the tapping process.

DETAILED DESCRIPTION

[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0018] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0019] refer to Figures 1 to 13A tapping device for manufacturing mechanical metal parts provided by an embodiment of the present invention comprises a mounting plate 1, a support frame 2 is fixedly connected to the bottom of the mounting plate 1, a sliding sleeve 3 and a controller 4 are fixedly connected to the top of the mounting plate 1, and a tapping mechanism is also included, wherein the tapping mechanism comprises a tap 5 for tapping and a tapping member 6 for driving the tap 5 to rotate, one side of the tapping member 6 is slidably connected to the inside of the sliding sleeve 3, the tap 5 is rotatably connected to the bottom of the tapping member 6, a sliding drive component 7 for driving the tapping member 6 to slide up and down is arranged above the sliding sleeve 3, and the sliding drive component 7 and the tapping member are connected to each other. 6 transmission connection, clamping mechanism, the clamping mechanism includes a hollow column 8 arranged above the mounting plate 1, a rubber pad 9 is fixedly connected above the hollow column 8, a fixing plate 10 evenly distributed around the hollow column 8 is fixedly connected above the mounting plate 1, a clamping assembly for horizontally clamping the spherical part is arranged above the fixing plate 10, a pressing assembly for vertically pressing the spherical part is arranged above the clamping assembly, and an air control assembly is arranged below the mounting plate 1, the air control assembly can absorb air from the hollow column 8 and drive the clamping assembly and the pressing assembly to clamp the spherical part.

[0020] When in use, the spherical part is placed above the hollow column 8, and then the sliding drive assembly 7 (which drives the tapping part 6 to slide up and down through the motor and the screw, which is the same as the working principle of the prior art, and will not be described in detail here) controls the tapping part 6 (which drives the tap 5 to rotate through the motor for tapping, which is the same as the working principle of the prior art, and will not be described in detail here) to drive the tap 5 to move downward for a certain distance, and at the same time adjust the circular hole of the spherical part to be tapped to align it with the tap 5, and then continue to control the tap 5 to move downward until the end of the tap 5 is slightly inserted into the circular hole, thereby ensuring that the tapping position of the part is accurate and the initial tapping is completed. The position state of the spherical part is restricted in the first step, and then the air control component is started, which will absorb the air in the hollow column 8, and at the same time use the absorbed air to drive the clamping component and the pressing component to clamp and press the spherical part from the side and top respectively, so as to stably clamp the spherical part. In this process, because a rubber pad 9 is provided above the hollow column 8, after the spherical part is placed on the top of the hollow column 8, the hollow column 8 will enter a sealed state, and as the air control component absorbs the air inside the hollow column 8, the hollow column 8 will stably adsorb the spherical part on top of it, so that when the clamping component and the pressing component fail to effectively clamp the spherical part Before holding, the spherical part is initially fixed to prevent it from deflecting and falling. At the same time, as the air in the hollow column 8 gradually decreases, the suction force of the hollow column 8 on the spherical part will gradually increase. After the suction force reaches the peak, it will cooperate with the pressing component and the clamping component to completely fix the spherical part. When the pressing component presses the spherical part, it will increase the squeezing force of the spherical part on the rubber pad 9 below, thereby effectively preventing the hollow column 8 from leaking. After the spherical part is completely fixed, the tapping component 6 will drive the tap 5 to rotate, and the sliding drive component 7 will drive the tap 5 to move downward, thereby completing the tapping. After the tapping is completed, the tap 5 is reset to the top, and the air control component injects air into the hollow column 8 in the reverse direction to drive the clamping component and the pressing component to reset, and at the same time eliminate the suction of the hollow column 8 on the spherical part, and then the spherical part is removed for the next tapping. Through this setting, the hollow column 8 can be used to absorb the spherical part, so as to quickly and efficiently perform preliminary positioning of the spherical part. At the same time, combined with the clamping component and the pressing component, the spherical part can be fully fixed from multiple directions to prevent abnormal movement during tapping, thereby effectively improving the tapping and use effect of the equipment.

[0021] Furthermore, the clamping assembly includes a clamping drive unit fixedly connected to the top of the fixing plate 10, and the output end of the clamping drive unit is provided with a fitting unit capable of fitting to the outer surface of the spherical part. The clamping drive unit includes a first air sleeve 11 fixedly connected to the top of the fixing plate 10, and a first plug rod 12 is slidably inserted in the first air sleeve 11, and one end of the first plug rod 12 located in the first air sleeve 11 is fixedly connected to a first piston 13, and one end of the first plug rod 12 away from the first piston 13 is fixedly connected to a mounting rod 14, and the fitting unit includes a rubber sheet 15 for contacting the surface of the spherical part, and one side of the rubber sheet 15 is fixedly connected to a plurality of sliding blocks 16 A sliding groove is provided on the side of the mounting rod 14 away from the first air sleeve 11, and the sliding block 16 is slidably connected to the sliding groove. A first spring 17 is fixedly connected to the side of the sliding block 16 close to the first air sleeve 11, and one end of the first spring 17 away from the sliding block 16 is fixedly connected to the sliding groove. The pressing assembly includes a second air sleeve 18 fixedly connected to the top of the mounting rod 14, a second plug rod 19 is slidably inserted in the second air sleeve 18, and one end of the second plug rod 19 located in the second air sleeve 18 is fixedly connected to a second piston 20, and the end of the second plug rod 19 away from the second piston 20 is provided with a pressing piece for pressing a spherical part.

[0022] During use, the air sucked from the hollow column 8 by the air control component will be injected into the first air sleeve 11 from the rear of the first air sleeve 11, and the air injected into the first air sleeve 11 will push the first piston 13 to drive the first insertion rod 12 to extend out of the first air sleeve 11, thereby pushing the installation rod 14 to drive the rubber sheet 15 to approach the spherical part. After the rubber sheet 15 contacts the outer surface of the spherical part, due to the soft nature of the rubber sheet 15, the part of the rubber sheet 15 that first contacts the spherical part will first drive the sliding block 16 behind it to press the first spring 17, and the remaining sliding blocks 16 will press the first spring 17 fixedly connected thereto in turn as the first insertion rod 12 continues to advance, so that the rubber sheet 15 can adapt to spherical parts of different sizes and ensure that it is completely fitted with the surfaces of spherical parts of different sizes. After the sliding block 16 that first contacts the spherical part is pressed After being pressed to the limit, the first insertion rod 12 stops advancing. At this time, the sliding block 16 pressed to the limit will stably clamp the spherical part, and the remaining sliding blocks 16 will make the rubber sheet 15 fit stably with the surface of the spherical part, and at the same time play a certain clamping and limiting role. When the first air sleeve 11 is injected with air, the second air sleeve 18 will also be injected with air sucked from the hollow column 8. The air injected into the second air sleeve 18 will push the second piston 20 to drive the second insertion rod 19 to extend out of the second air sleeve 18, thereby pushing the pressing piece to press the spherical part. Through this setting, the spherical part can be clamped horizontally and vertically. At the same time, multiple independent sliding blocks 16 are used to make the rubber sheet 15 fit fully with the surface of the part when dealing with spherical parts of different sizes, thereby effectively improving the clamping effect of the equipment, and then improving the tapping effect of the equipment.

[0023] Furthermore, the air control component includes a mounting sleeve 21 fixedly connected to the bottom of the mounting plate 1, a driving airbag 22 is placed in the mounting sleeve 21, the driving airbag 22 and the first air sleeve 11, and the driving airbag 22 and the second air sleeve 18 are connected through a hose, an air pump 23 with an air intake port and an air exhaust port is fixedly connected below the mounting sleeve 21, the exhaust port of the air pump 23 is connected to the driving airbag 22 through a hose, and the air intake port of the air pump 23 is also connected to the inside of the hollow column 8 through a hose, the hollow column 8 is slidably connected above the mounting plate 1, a sliding plate 24 is fixedly connected below the hollow column 8, the sliding plate 24 is slidably connected in the mounting sleeve 21, and the sliding plate 24 is located above the driving airbag 22, a second spring 25 is fixedly connected above the sliding plate 24, and the end of the second spring 25 away from the sliding plate 24 is fixedly connected below the mounting plate 1.

[0024] When in use, in the initial state, the driving airbag 22 is vacuum. When clamping is required, the air pump 23 will suck air from the inside of the hollow column 8 through the suction port, and discharge the air into the driving airbag 22 from the exhaust port first. As the air enters, the driving airbag 22 will lift the upper sliding plate 24 and compress the second spring 25 upward. At the same time, the hollow column 8 above the sliding plate 24 will also be driven to rise. As the air in the driving airbag 22 continues to increase, the air will enter the first air sleeve 11 and the second air sleeve 18 through the hose to push the first insertion rod 12 and the second insertion rod 19 to extend, thereby achieving the clamping of the spherical part. When air can no longer be injected into the driving airbag 22, the spherical part is stably clamped, and the hollow column 8 rises to the limit position, and then the tap 5 is controlled to tap the spherical part. At this time, the tap 5 needs to be combined with the downward pushing force of the sliding drive assembly 7 to achieve tapping. When the tap 5 is pushed downward, it will drive the spherical part to drive the sliding plate 24 generates a downward squeezing tendency on the driving airbag 22, and at this time the air in the driving airbag 22 is at its peak value and it will not be squeezed down, but because it is connected to the first air sleeve 11 and the second air sleeve 18, the squeezing tendency of the sliding plate 24 on the driving airbag 22 will be converted into a further clamping tendency of the pressing piece and the sliding block 16 on the spherical part, so that the spherical part can be self-locked and clamped more stably. After the tapping is completed, the air pump 23 reversely sucks the air in the driving airbag 22, so that the air in the first air sleeve 11 and the second air sleeve 18 is discharged, and then the first plug rod 12 and the second plug rod 19 are reset, and the second spring 25 is used to push the sliding plate 24 to reset. Through this setting, the first plug rod 12 and the second plug rod 19 can be driven by sucking the air in the hollow column 8, and the pressing force of the tap 5 on the spherical part can be used to achieve the self-locking of the part, thereby further improving the clamping and fixing effect of the equipment and ensuring the efficient and stable operation of the equipment.

[0025] Furthermore, a plurality of air suction holes 26 are provided above the rubber sheet 15, and the air suction holes 26 are connected to the air suction port of the air pump 23 through a hose. A coolant nozzle 27 is fixedly connected below the tapping member 6, and the pressing member includes a threaded rod 28 slidably inserted into the end of the second plug rod 19 away from the second piston 20, and a pressing block 29 is fixedly connected to the end of the threaded rod 28 away from the mounting rod 14, and adjusting nuts 30 are threadedly connected to the threaded rod 28 on both sides of the second plug rod 19.

[0026] During use, while the air pump 23 draws air from the hollow column 8, it also draws air through the air intake hole 26. When the rubber sheet 15 is completely fitted with the surface of the spherical part, the air intake hole 26 is sealed. As the air pump 23 continues to inhale air, the air intake hole 26 will also have an adsorption effect on the spherical part similar to that of the hollow column 8, thereby further improving the clamping and fixing effect of the sliding block 16 on the spherical part. At the same time, before tapping the spherical part, a small amount of coolant can be sprayed onto the surface of the spherical part through the coolant nozzle 27, so that a small amount of coolant adheres to the surface of the spherical part. After the rubber sheet 15 is completely fitted with the surface of the spherical part, it can play a sealing role, thereby preventing air from entering the air intake hole 26 at this time, thereby ensuring the adsorption effect of the air intake hole 26 on the spherical part, and when tapping, the spherical part and the tap 5 are not The friction between the rubber sheet 15 and the spherical part will cause the temperature of the surface of the spherical part to rise. At this time, the coolant between the rubber sheet 15 and the spherical part can play a cooling role, thereby reducing the temperature impact of the surface of the spherical part on the rubber sheet 15. When dealing with spherical parts of different sizes, the extension length of the threaded rod 28 can be adjusted by rotating the adjusting nut 30, and then the position of the pressing block 29 can be adjusted, so that it can always be in the most ideal pressing position when dealing with spherical parts of different sizes, thereby ensuring the pressing and clamping effect of the spherical parts. Through this setting, the suction hole 26 can be used to further limit the clamping position of the spherical part to prevent it from being displaced during tapping and clamping. At the same time, by setting the adjusting nut 30, the applicability of the equipment can be effectively improved, making the equipment suitable for spherical parts of different sizes, thereby further improving the tapping and use effects of the equipment.

[0027] Working principle of the present invention: When in use, the spherical part must first be placed on the top of the hollow column 8. Then, the sliding drive assembly 7 is used to control the tapping part 6, and the tapping part 6 drives the tap 5 through the motor to perform rotary tapping. During the downward movement of the tap 5, the position of the circular hole on the spherical part needs to be adjusted so that it is accurately aligned with the tap 5. Then, the tap 5 is driven deeper into the circular hole until its tip is slightly embedded in the hole to ensure the accuracy of the tapping position and initially stabilize the spherical part. Next, the air control assembly is started, which will extract the air in the hollow column 8 and use this airflow to activate the clamping assembly and the pressing assembly to clamp and press the spherical part from the side and top respectively to achieve a stable clamping. It is worth noting that the rubber pad 9 equipped on the top of the hollow column 8 will form a sealed environment after the spherical part is placed. As the air control assembly is extracted, the hollow column 8 will use suction to initially fix the spherical part to prevent it from shifting or falling. As the air is continuously extracted, the suction force gradually increases until it reaches a peak value, at which point the clamping assembly and the pressing assembly will work together to achieve complete fixation of the spherical part. In the process of applying pressure to the pressing assembly, the squeezing of the spherical part on the rubber pad 9 will be enhanced, effectively preventing the hollow column 8 from leaking. After the spherical part is stabilized, the tapping member 6 will drive the tap 5 to rotate and move downward to complete the tapping operation. After the tapping is completed, the tap 5 automatically resets to the initial position, and at the same time the air control assembly operates in reverse to inject air into the hollow column 8, resetting the clamping assembly and the pressing assembly, and releasing the suction force on the spherical part. The spherical part can then be easily removed to prepare for the next tapping operation. This design cleverly uses the suction force of the hollow column 8 to initially limit the spherical part, and combines the multi-directional fixation of the clamping assembly and the pressing assembly to effectively prevent abnormal movement during the tapping process, significantly improving the tapping efficiency and stability of the equipment.
