Detailed Implementation

[0013] 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.

[0014] Please see Figure 1-3 This utility model provides a technical solution: an ACME thread chip breaking machining device, including a machine tool body 1, which serves as the supporting structure for the entire device. A main control box 2 is located at one end of the machine tool body 1. The main control box 2 is responsible for controlling the operation of the entire machining device, including the clamping and rotation of the workpiece chuck 3, the movement of the tool assembly 5, and the activation of the water supply assembly 9. A rotatable workpiece chuck 3 is located at the output end of the main control box 2. The workpiece chuck is used to clamp and fix the pipe to be processed. It can rotate to ensure the stability of the pipe during processing, thereby ensuring the accuracy and quality of thread processing. A moving mechanism 4 is located at the other end of the machine tool body 1. The moving mechanism 4 is used to adjust the position of the tool assembly 5. A tool assembly 5 that can extend into the pipe is installed on the moving mechanism 4. The tool assembly 5 is used to process high-precision thread structures on the inner wall of the pipe. A connecting pipe 6 is also installed on the moving mechanism 4. A cavity 7 is located at the end of the connecting pipe 6 near the workpiece chuck 3, and several evenly distributed nozzles 8 are located at the end of the cavity 7 away from the workpiece chuck 3. Nozzle 8 is used to uniformly spray cooling water onto the processing area. The machine tool body 1 is equipped with a water supply component 9 connected to the other end of the connecting pipe 6. The water supply component 9 delivers cooling water to the connecting pipe 6, ensuring the stability and flexibility of the water supply. A collection component 10 is provided on the machine tool body 1, located below the workpiece chuck 3 and the moving mechanism 4, for cleaning and recycling debris. During processing, the moving mechanism 4 drives the tool assembly 5 and the connecting pipe 6 to extend into the pipe. The tool assembly 5 performs high-speed cutting on the inner wall of the pipe to produce a high-precision ACME thread structure. At the same time, the water supply component 9 delivers cooling water to the cavity 7 through the connecting pipe 6, and then uniformly sprays it onto the processing area through nozzle 8. The cooling water carries away the heat generated by the friction between the tool and the workpiece, preventing the tool from overheating, extending the tool life, and cleaning the debris generated during processing. The cooling water flushes from the inside of the pipe to the outside, effectively cleaning debris, avoiding interference with subsequent processing, and improving processing efficiency. The cooling water and debris flow into the collection component 10 for convenient subsequent processing and recycling.

[0015] Specifically, the moving mechanism 4 includes a lead screw module 41 mounted on the machine tool body 1. The lead screw module 41 is the core part of the moving mechanism. It consists of a lead screw and a nut, which can convert rotary motion into linear motion. The moving end of the lead screw module 41 is provided with a mounting platform 42, which is fixed to the moving end of the lead screw module 41. The mounting platform 42 has sufficient rigidity and stability to ensure that the components do not shake or shift during the movement. A connecting seat 43 is slidably mounted on the mounting platform 42. The connecting seat 43 is a fixed base for the tool assembly 5 and the connecting pipe 6. It secures the tool assembly 5 and the connecting pipe 6 to the moving mechanism 4 by bolt fixing. Both the tool assembly 5 and the connecting pipe 6 are fixedly mounted on the connecting seat 43. The mounting platform 42 is also provided with a hydraulic cylinder 44 for driving the moving of the connecting seat 43. The hydraulic cylinder 44 is an actuator that can provide linear motion. It pushes the piston rod by the pressure of hydraulic oil, thereby driving the connecting seat 43 to slide on the mounting platform 42. The hydraulic cylinder can be controlled via the main control box 2. The moving speed and position of the connecting seat can be adjusted according to the processing requirements to ensure the precise movement of the tool assembly and connecting pipe during the processing. At the start of processing, the moving mechanism 4 drives the mounting platform 42 to move via the lead screw module 41, so that the connecting seat 43, carrying the tool assembly 5 and connecting pipe 6, extends into the pipe. The hydraulic cylinder 44 adjusts the position of the connecting seat 43 according to the processing requirements to ensure that the tool assembly 5 and connecting pipe 6 are in the correct position and angle. During processing, the tool assembly 5 performs high-speed cutting on the inner wall of the pipe to produce a high-precision ACME thread structure. At the same time, the connecting pipe 6 sprays cooling water evenly onto the processing area through the nozzle 8 to remove heat and clean up debris. After processing is completed, the moving mechanism 4 drives the tool assembly and connecting pipe to exit the pipe, completing one processing cycle.

[0016] Specifically, the tool assembly 5 includes a tool holder 51 fixedly mounted on the moving mechanism 4, ensuring that the tool assembly can accurately enter the interior of the pipe as the moving mechanism moves. The tool holder is typically made of a high-rigidity, high-strength material to withstand various forces and vibrations generated during processing. Its design must possess sufficient stability and durability to prevent bending or deformation during high-speed cutting, thereby ensuring processing accuracy. The end of the tool holder 51 is equipped with a cutter head 52, which is an ACME thread cutter head. The cutter head 52 is a key part of the tool assembly and adopts an ACME thread cutter head design. ACME threads have a large thread helix angle, which allows the cutter head to remain stable during high-speed cutting, ensuring high precision and surface quality in thread processing. At the start of processing, the moving mechanism 4 drives the tool assembly 5 into the interior of the pipe, and the cutter head 52 contacts the inner wall of the pipe. The tool assembly performs a feed motion under the drive of the moving mechanism, and the cutter head 52 cuts the inner wall of the pipe to produce a high-precision ACME thread structure.

[0017] Specifically, the water supply assembly 9 includes a water tank 91 mounted on the machine tool body 1 for convenient storage and management of cooling water. The machine tool body 1 also has a water inlet pipe 92 extending into the water tank 91. The water inlet pipe 92 extends from the machine tool body 1 into the water tank 91, responsible for drawing cooling water from the water tank. A water pump 93 is mounted on the side wall of the water inlet pipe 92, responsible for pressurizing the cooling water in the water tank 91 and delivering it to subsequent systems through the water inlet pipe 92. Its working principle is based on the centrifugal force generated by the rotation of the impeller, which draws water from the water tank 91 and pressurizes it for delivery. The water inlet pipe 93 is usually controlled by the main control box 2 and can be adjusted according to... The water supply pressure and flow rate are adjusted according to processing requirements to ensure that the cooling water supply meets the processing requirements. A spiral hose 94 is provided between the end of the water supply pipe 92 and the connecting pipe 6. The spiral hose 94 has good flexibility and torsional resistance, which can adapt to the adjustment of the moving mechanism at different positions and angles, avoiding the restriction and damage caused by rigid pipe connection. At the start of processing, the water supply pump 93 starts, draws and pressurizes the cooling water in the water tank 91 through the water supply pipe 92, and then delivers it to the connecting pipe 6 through the spiral hose 94. The cooling water enters the cavity 7 through the connecting pipe 6, and is then sprayed onto the processing area by evenly distributed nozzles 8. The cooling water acts directly on the contact surface between the tool and the workpiece, carrying away the generated heat and preventing the tool from overheating. At the same time, it cleans up the debris generated during processing to avoid interference with subsequent processing. The sprayed cooling water and debris flow into the collection assembly 10.

[0018] Specifically, the collection component 10 includes a wastewater collection tank 101 disposed on the machine tool body 1 and located below the workpiece chuck 3 and the moving mechanism 4. A debris collection box 102 is provided on the machine tool body 1 and on one side of the wastewater collection tank 101. A U-shaped filter screen 103 is provided at the upper end of the wastewater collection tank 101. A drive motor 104 is provided on the side wall of the machine tool body 1. The drive end of the drive motor 104 is provided with a spiral conveying auger 105 adapted to the arc surface of the U-shaped filter screen 103. During the processing, cooling water is sprayed into the processing area through the nozzle 8 to remove heat and clean up debris. The wastewater and debris eventually flow into the wastewater collection tank 101; the U-shaped filter screen 103 on the wastewater collection tank 101 separates the debris from the wastewater, preventing the debris from entering the subsequent treatment system or being discharged from the machine tool; the drive motor 104 drives the screw conveyor 105 to move the filtered debris along the conveying channel to the debris collection box 102 for easy subsequent cleaning and treatment; the filtered wastewater remains in the wastewater collection tank 101 and can be recycled or further treated to reduce water waste and environmental pollution.

[0019] Working principle: When this utility model is in operation, the pipe to be processed is fixed on the output end of the main control box 2, i.e., the workpiece chuck 3. The workpiece chuck 3 can drive the pipe to rotate. The moving mechanism 4 drives the mounting platform 42 to move through the lead screw module 41, so that the connecting seat 43, carrying the tool assembly 5 and the connecting pipe 6, extends into the inside of the pipe. The hydraulic cylinder 44 adjusts the position of the connecting seat 43 according to the processing requirements to ensure that the tool assembly 5 and the connecting pipe 6 are in the correct position and angle. The tool assembly 5 performs high-speed cutting on the inner wall of the pipe to process a high-precision ACME thread structure. At the same time, the water supply assembly 9 draws and pressurizes the cooling water from the water tank 91 and delivers it to the connecting pipe 6 through the water supply pipe 92 and the spiral hose 94. After the cooling water enters the cavity 7, it is evenly sprayed onto the processing area through the evenly distributed nozzles 8. The cooling water washes from the inside of the pipe to the outside of the pipe. The cooling water and debris flow into the collection assembly 10 for processing and recycling.
