Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, and in particular to a fast automatic tapping machine. Background Technology

[0002] High-speed automatic tapping machines are automated devices for machining internal threads. Their working principle involves using mechanical or hydraulic transmission to convert the rotational motion of a motor into the rotation and feed motion of a tap. After the workpiece is fixed on the worktable, the tap operates under the drive of the motor. In mechanical manufacturing, they are used for thread machining of parts in engines, machine tools, and automobiles; in hardware processing, they can handle the internal threads of products such as doors, windows, and furniture; in electronic equipment manufacturing, they process the threads of small parts; and in the construction industry, they process the internal threads of steel structure connecting bolts. They offer high processing efficiency, high precision, simple operation, wide applicability, and a high degree of automation.

[0003] Existing high-speed automatic tapping machines typically consist of several key components working together. The core component is the spindle system, which includes a high-precision spindle and a connected tap chuck. Driven by a power source, the spindle rotates at high speed, driving the tap to perform the tapping operation. Some advanced tapping machines have spindle speed adjustment functions to adapt to the processing requirements of different materials and thread specifications. The feed system is also crucial, generally consisting of guide rails, sliders, lead screw and nut pairs, or other transmission components. It is responsible for precisely controlling the tap's feed depth and speed, ensuring the accuracy and quality of thread processing. Some also employ closed-loop control systems to monitor and adjust feed parameters in real time. In addition, there is a worktable and clamping device. The worktable is used to place and fix the workpiece to be processed, and the clamping device firmly holds the workpiece using mechanical, pneumatic, or hydraulic means to prevent displacement during the tapping process.

[0004] However, existing clamping devices are typically unable to adjust to the shape of the object, leading to numerous adverse effects. For irregularly shaped workpieces, the clamping device cannot adaptively fit, causing excessive localized stress during clamping, resulting in surface damage, affecting the workpiece's appearance quality and dimensional accuracy, and even leading to workpiece scrap and increased production costs. Simultaneously, the inability to clamp tightly and evenly results in workpiece displacement or wobbling during tapping, causing tapping position deviations and severely reducing thread accuracy, failing to meet high-precision production requirements and significantly lowering product yield. Furthermore, this mismatched clamping method reduces tapping efficiency, requiring frequent machine stops to readjust workpiece position or change clamping methods, greatly wasting time and labor costs, hindering large-scale, efficient production, and limiting the application of rapid automatic tapping machines in the processing of complex-shaped workpieces. Therefore, a rapid automatic tapping machine is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fast automatic tapping machine, which aims to improve the problem in the prior art that the inability to adaptively hold the tool leads to an increased probability of workpiece breakage during tapping, thereby reducing the stability of the workpiece during tapping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-speed automatic tapping machine includes a housing, a controller fixedly connected to the side wall of the housing, a base fixedly connected to the bottom of the controller, a hydraulic cylinder fixedly connected to the bottom of the housing, a connecting plate fixedly connected to the output end of the hydraulic cylinder, and a clamping assembly provided on the top of the connecting plate;

[0008] The clamping assembly includes a movable block, the bottom of which is fixedly connected to the top of the connecting plate, the bottom of which is slidably connected to the outer wall of the slide rail, a first rotating plate is rotatably connected inside the movable block, a second rotating plate is rotatably connected inside the first rotating plate, a third rotating plate is rotatably connected inside the second rotating plate, and a filter assembly is provided inside the outer shell.

[0015] As a further description of the above technical solution:

[0016] A water pump is fixedly connected inside the second material container, and a suction pipe is fixedly connected to the input end of the water pump;

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the moving block is driven to move by the output end of the hydraulic cylinder. The moving block drives the first rotating plate to come close to the surface of the workpiece. After the first rotating plate comes close, it drives the second rotating plate and the third rotating plate to rotate respectively, achieving the effect of adaptive clamping. This solves the problem that adaptive clamping of the workpiece cannot effectively fix the workpiece during tapping, which causes the workpiece to shake and increases the breakage rate. This improves the stability of the tapping machine.

[0023] 2. In this utility model, the coolant flows into the flow tube through the first filter plate and into the first material box. Then, suction is generated through the second connecting pipe, allowing the coolant to be filtered through the second filter plate. Finally, the coolant is discharged through the output end of the second connecting pipe, achieving the effect of efficient coolant filtration. This solves the problem of inefficient coolant filtration and increased coolant procurement, and improves the practicality of the tapping machine. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a rapid automatic tapping machine, including a housing 1. The housing 1 is preferably made of aluminum alloy. Aluminum alloy is lightweight, facilitating the handling and installation of the equipment. A controller 3 is fixedly connected to the side wall of the housing 1, and a base 4 is fixedly connected to the bottom of the controller 3. The base 4 is preferably made of cast iron. Cast iron has high density and mass, providing a stable and solid support foundation for the entire tapping machine. A hydraulic cylinder 7 is fixedly connected to the bottom of the housing 1, and a connecting plate 8 is fixedly connected to the output end of the hydraulic cylinder 7. A clamping assembly is provided on the top of the connecting plate 8.

[0032] The clamping assembly includes a movable block 5, the bottom of which is fixedly connected to the top of the connecting plate 8, and the bottom of which is slidably connected to the outer wall of the slide rail 6. The movable block 5 and the slide rail 6 can be made of high-quality carbon steel. The steel after quenching and tempering has good comprehensive mechanical properties and moderate hardness, which ensures the smoothness of the movable block 5 when sliding on the slide rail 6 and reduces frictional resistance. The movable block 5 is rotatably connected to a first rotating plate 18, the first rotating plate 18 is rotatably connected to a second rotating plate 19, and the second rotating plate 19 is rotatably connected to a third rotating plate 20. It is ideal to use stainless steel for the first rotating plate 18, the second rotating plate 19 and the third rotating plate 20. Stainless steel has excellent corrosion resistance and is not easy to rust in working environments where it comes into frequent contact with coolant, chips and other materials. It can maintain flexible rotation for a long time. A filter assembly is installed inside the outer shell 1.

[0033] Specifically, when using the tapping machine, the workpiece to be tapped is first carefully placed at a predetermined position on the top of the housing 1. Then, the hydraulic cylinder 7 is activated, its output end applying power and driving the connected plate 8 to move smoothly along a specific guide track. As the connected plate 8 moves, the moving block 5, which is fastened to it, also moves synchronously. During this process, due to the linkage between the structures, when the connected plate 8 drives the moving block 5, it cleverly triggers the internal first rotating plate 18, causing it to rotate around a specific axis. The rotation of the first rotating plate 18, through a carefully designed transmission mechanism, drives the second rotating plate 19, causing it to also enter a rotating state. Next, the rotation of the second rotating plate 19 further drives the internal third rotating plate 20 to rotate as well. As these rotating plates gradually conform to the surface of workpieces of various shapes, they can automatically adjust their clamping posture and force according to the contour shape of the workpiece, thus effectively achieving adaptive clamping and laying a solid foundation for subsequent precise and stable tapping operations.

[0034] Reference Figure 1 and Figure 3The filter assembly includes a fixing plate 21, which can be made of aluminum alloy. Aluminum alloy is lightweight and strong, making it easy to install and fix inside the housing 1, and can stably support the first filter plate 9 and other related components. The side wall of the fixing plate 21 is fixedly connected to the inside of the housing 1, and the first filter plate 9 is fixedly connected inside the fixing plate 21. The first filter plate 9 is preferably made of stainless steel wire mesh. Stainless steel wire mesh has high strength and corrosion resistance, and can effectively intercept larger particulate impurities in the coolant, such as metal shavings and clumps of chips. A flow pipe 10 is fixedly connected to the bottom of the first filter plate 9, and the flow pipe 10 can be made of engineering plastic, such as PVC pipe. PVC pipes possess excellent corrosion resistance, chemical stability, and a certain degree of flexibility, facilitating easy pipe laying and connection. This ensures that the coolant does not leak during the flow from the first filter plate 9 to the first loading tank 11. The first loading tank 11 is fixedly connected to the side wall of the flow pipe 10. A first connecting pipe 12 is fixedly connected to the side wall of the first loading tank 11. A second loading tank 17 is fixedly connected to the side wall of the first connecting pipe 12. Both the first loading tank 11 and the second loading tank 17 are suitable for use with polyethylene plastic. Polyethylene plastic has good corrosion resistance and sealing properties, enabling the safe storage of filtered and further processed coolant, preventing coolant leakage from damaging other components of the equipment. A second filter plate 16 is fixedly connected inside the second loading tank 17. The second filter plate 16 can be made of multi-layer composite filter paper. This material can filter the coolant more finely, removing tiny impurities that remain after passing through the first filter plate 9, such as metal particles and oil particles. A water pump 14 is fixedly connected inside the second loading box 17. A suction pipe 15 is fixedly connected to the input end of the water pump 14. One end of the suction pipe 15 is fixedly connected to the inside of the second loading box 17. A second connecting pipe 13 is fixedly connected to the output end of the water pump 14. The other end of the second connecting pipe 13 is set on the outer wall of the outer shell 1. The outer wall of the outer shell 1 is fixedly connected to the side wall of the chipper 2.

[0035] Specifically, when the chip cutter 2 starts working and generates coolant, the coolant flows into the internal space of the housing 1 under gravity. At this time, the first filter plate 9, located at a specific position inside the housing 1, first plays its role in initially filtering the coolant, intercepting larger particles of impurities such as metal shavings and oil clumps, ensuring that the coolant entering the subsequent pipes is relatively clean. The coolant that has undergone initial filtration then flows orderly through the first filter plate 9 into the connected flow pipe 10, and smoothly flows into the first loading tank 11 for temporary storage. Subsequently, the water pump 14 starts and generates strong suction, using the first connecting pipe 12 to draw the coolant from the first loading tank 11 into the second loading tank 17. After the coolant enters the second loading tank 17, the second filter plate 16 performs a second, more refined filtration, further removing fine impurity particles such as residual metal powder and tiny impurity particles, thereby improving the purity and quality of the coolant. Next, the suction pipe 15 draws the coolant into the water pump 14 under the suction force of the water pump 14. After being pressurized by the water pump 14, the coolant is precisely flowed back into the chip cutter 2 through the second connecting pipe 13. This achieves efficient filtration of the coolant and good results in the secondary use of the coolant. While ensuring the recycling of the coolant, it effectively improves the efficiency and quality of coolant use, reduces coolant waste and environmental pollution, and provides strong support and guarantee for the stable and efficient operation of the tapping machine.

[0036] Working Principle: When using the tapping machine, the workpiece is first placed on top of the outer casing 1. Then, the output end of the hydraulic cylinder 7 drives the connecting plate 8 to move. The movement of the connecting plate 8 drives the moving block 5 to move. When the connecting plate 8 drives the moving block 5, it causes the first rotating plate 18 inside to rotate. The rotation of the first rotating plate 18 also causes the second rotating plate 19 to rotate. The rotation of the second rotating plate 19 then causes the third rotating plate 20 inside to rotate as well. During this process, the plate 20 adheres to the workpiece, thus rotating and achieving an adaptive clamping effect. Subsequently, the chip cutter 2 generates coolant, which flows into the interior of the outer casing 1. The coolant is then initially filtered through the first filter plate 9, and then flows into the flow pipe 10 through the first filter plate 9. The coolant then flows into the first loading tank 11 through the flow pipe 10. The water pump 14 generates suction, and the coolant is then drawn into the second loading tank 17 through the first connecting pipe 12. Next, the coolant undergoes a second filtration through the second filter plate 16. Then, the second connecting pipe 13 draws the coolant into the water pump 14 through the suction pipe 15 through the input end. Finally, the coolant flows into the chip cutter 2 through the output end of the water pump 14 and the second connecting pipe 13, achieving the effect of efficient filtration and reuse of coolant.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
