Description

Technical Field

[0001] This utility model relates to the field of machining and tapping machine technology, and in particular to a machining and tapping machine for ductile iron pipe fittings tees. Background Technology

[0002] Ductile iron pipe tees are widely used in various engineering fields due to their excellent strength, corrosion resistance, and sealing performance. Tapping, as a crucial step in pipe fitting processing, is essential to the connection quality and overall performance of the pipe fitting. Existing tapping machines often suffer from low efficiency, unstable pipe fixing, and easy damage to the pipe fittings when processing ductile iron pipe tees. To solve these problems, a new type of tapping machine for processing ductile iron pipe tees has been designed to meet the requirements of efficient, precise, and stable processing.

[0003] CN117884722A discloses a tapping machine for machining ductile iron pipe tees, comprising a tapping machine body and an adjusting and fixing device. The adjusting and fixing device is located at the upper end of the tapping machine body, and a tapping assembly is located on one side of the upper end of the tapping machine body. A cleaning assembly is located inside the adjusting and fixing device. A fixing adjustment component is located inside the middle of the tapping machine body, and a lower connecting plate is located at the upper end of the fixing adjustment component. A first clamping component is located at the upper end of the lower connecting plate. This invention reduces workload and improves efficiency, allowing for the simultaneous fixing of six ductile iron pipes. The fixing process is convenient, increasing the stability of the fixed ductile iron pipes and reducing deviation during tapping. It also provides a certain buffering effect on the ductile iron pipes, preventing wear from the semi-convex arc ring on the outer surface of the ductile iron pipes and reducing their corrosion resistance. However, it does not solve the problems of easily adapting to clamping tees of different sizes for drilling and tapping and improving the safety of the device during processing. Therefore, we propose a tapping machine for machining ductile iron pipe tees. Utility Model Content

[0004] The purpose of this utility model is to provide a tapping machine for machining ductile iron pipe fittings tees.

[0005] To achieve the objectives proposed in the aforementioned prohibited technology regarding facilitating the drilling and tapping of T-tubes of different sizes and improving the safety of the device during processing, this utility model provides the following preferred technical contents; A tapping machine for ductile iron pipe fittings includes a fixed base and a clamping assembly. The clamping assembly is fixedly connected to the top of the fixed base. The clamping assembly includes an installation plate, two electric guide rails, and two sets of electric sliding blocks slidably connected inside each of the two electric guide rails. A device mounting shell is fixedly connected to the top of each set of electric sliding blocks. A side-mounted servo motor is installed inside the device mounting shell. The output end of the side-mounted servo motor is rotatably connected to a rotating shaft via a coupling. A rotating mounting plate is fixedly connected at equal intervals to the outer ring surface of the rotating shaft on the side away from the coupling. The rotating mounting plate has three sliding grooves on its inner wall. Three sliders are fixedly connected inside each of the three sliding grooves. Three clamping bars are fixedly installed on the surface of each of the three sliders via a set of fixing bolts. Three vertically mounted electric push rods are fixedly connected to one side of each of the three sliders.

[0006] The fixed base located on both sides of the two electric guide rails is fixedly connected to a protective component. The protective component includes a protective cover, and a protective door is movably connected to the surface of the protective cover. The left and right sides of the protective cover have square holes.

[0007] Protective components, in the form of protective covers, are fixedly connected to the top of the fixed bases on both sides of the two electric guide rails to provide a protective barrier for the equipment's processing area. This prevents debris from flying during processing and ensures operator safety. A protective door is movably connected to the surface of the protective cover, allowing for flexible opening and closing and facilitating operator observation of the internal processing and material loading / unloading. Square openings on the left and right sides of the protective cover provide a channel for the horizontal movement and unloading of processed pipe fittings, facilitating their removal.

[0008] The protective cover has a vertically mounted hydraulic cylinder fixedly connected to the upper surface of its inner wall, and a machining and mounting shell is fixedly connected to the bottom of the vertically mounted hydraulic cylinder. A vertically mounted drive motor is fixedly installed inside the machining and mounting shell.

[0009] A vertically mounted hydraulic cylinder is fixedly connected to the upper surface of the inner wall of the protective cover to provide vertical driving force for the machining and mounting housing. This allows for precise control of the housing's lifting and lowering, ensuring it accurately reaches the machining position. The bottom of the vertically mounted hydraulic cylinder is fixedly connected to the machining and mounting housing, ensuring stable power transmission and precise lifting of the housing to guarantee the accuracy of the tapping position. A vertically mounted drive motor is fixedly installed inside the housing to provide power for the tapping operation, driving the tapping drill bit to rotate and complete the tapping of the tee pipe.

[0010] The vertical drive motor is rotatably connected to a support shaft via a coupling at its lower end. A tapping mounting plate is fixedly connected at equal intervals to the lower annular surface of the support shaft, and a tapping head is movably connected to the tapping mounting plate.

[0011] The lower end of the vertically mounted drive motor is rotatably connected to the support shaft via a coupling, efficiently transmitting the motor's rotational power to the support shaft and enabling it to rotate synchronously and stably with the motor. A tapping mounting plate is fixedly connected at equal intervals to the lower annular surface of the support shaft. The rotation of the support shaft drives the tapping mounting plate to rotate, providing rotational motion for the tapping head to tap the tee pipe. The tapping mounting plate and the tapping head are movably connected, allowing the tapping head to be flexibly adjusted or replaced on the tapping mounting plate according to processing requirements, thus adapting to the tapping requirements of different tee pipe specifications.

[0012] The fixed base has a feeding port on the top and an insertion port on one side, with a storage compartment slidably connected inside the insertion port. A controller is fixedly connected to the surface of the fixed base.

[0013] By opening a discharge port at the top of the fixed base, metal shavings generated during processing are collected, allowing them to fall downwards in a concentrated manner. An insertion port is provided on one side of the fixed base, allowing the storage bin to slide within the port, providing convenient installation and disassembly for easy collection and cleaning of processing shavings, facilitating centralized processing. A controller is fixedly connected to the surface of the fixed base, enabling centralized control of various equipment components, such as the electric guide rail, electric slider, side-mounted servo motor, vertically mounted hydraulic cylinder, and vertically mounted drive motor. This allows users to precisely adjust equipment operating parameters according to the processing requirements of different T-shaped pipes, improving the equipment's adaptability and ease of operation.

[0014] Compared with the prior art, this utility model provides a tapping machine for machining ductile iron pipe fittings tees, which has the following beneficial effects. This utility model discloses a tapping machine for ductile iron pipe fittings tees. An electric slider inside the electric guide rail can slide under the control of a controller. The movement of the electric slider within the electric guide rail adjusts the position of the mounting housing and connected components to accommodate different placement requirements. A side-mounted servo motor inside the mounting housing rotates, driving a rotating shaft via a coupling, which in turn rotates the rotating mounting plate. An electric slider within a groove on the inner wall of the rotating mounting plate, under the control of the controller, moves a clamping bar. This movement of the clamping bar clamps the horizontal and vertical connections of the tee pipes placed on one side of the rotating mounting plate, firmly securing tee pipes of different sizes for subsequent processing.

[0015] The protective cover of the protective assembly is fixed to the top of the fixed base on both sides of the two electric guide rails, providing protection for the equipment. A vertically mounted hydraulic cylinder fixed to the upper surface of the inner wall of the protective cover, through its telescopic movement, drives the machining and mounting housing connected to the bottom to rise and fall. Driven by the hydraulic cylinder, the height of the machining and mounting housing is precisely controlled, ensuring that the support shaft and tapping mounting plate connected to the lower end of the vertically mounted drive motor inside the housing accurately reach the position of the tee pipe to be processed. The vertically mounted drive motor rotates, driving the support shaft to rotate via a coupling, which in turn rotates the tapping mounting plate. The tapping head movably connected to the tapping mounting plate rotates accordingly, drilling and tapping the tee pipe. Through the coordinated operation of the drive motor and various connecting components, drilling and tapping operations are performed on the tee pipe openings at different positions, achieving the purpose of meeting the processing requirements of the tee pipe.

[0016] Square openings are provided on both sides of the protective cover. The user stands on one side of the cover and moves the mounting shell and the processed T-pipe into the square openings by controlling an electric slider. This design allows the user to easily transport the processed T-pipe from one side of the protective cover, avoiding the need for the user to directly reach inside and reducing safety risks.

[0017] In summary, as described above, the device's clamping components are designed to accommodate drilling and tapping of T-tubes of different sizes. Furthermore, the well-designed protective cover, including protective doors and square openings on both sides, enhances the device's safety during processing, enabling it to better meet actual production needs.

[0018] This utility model discloses a tapping machine for ductile iron pipe fittings tees. A discharge port on the top of the fixed base guides metal shavings and other waste materials generated during tee pipe processing downwards, achieving a concentrated collection of waste. An insertion port on one side of the fixed base houses a storage bin that slides within it. When waste falls through the discharge port, it enters the storage bin. This structural design facilitates the centralized collection of waste generated during processing, enabling convenient subsequent cleaning and disposal. The storage bin can be easily inserted or pulled out through the insertion port, allowing operators to conveniently remove it for waste disposal after processing, further demonstrating its convenience in waste collection.

[0019] The controller, fixedly connected to the surface of the base, serves as the core control unit of the entire equipment. It connects to various key components such as the electric guide rail, electric slider, side-mounted servo motor, vertically mounted hydraulic cylinder, and vertically mounted drive motor. Through the controller, operators can issue various commands to achieve precise control of these components. For example, the controller can control the movement of the electric slider within the electric guide rail, thereby adjusting the position of the clamping assembly to clamp T-shaped pipes of different sizes; it can also control the extension and retraction of the vertically mounted hydraulic cylinder, ensuring that the machining mounting shell and tapping components accurately reach the machining position. This comprehensive and precise control method meets different processing needs and allows for flexible adjustment of the equipment's operating status, making equipment operation more convenient and efficient.

[0020] In summary, the coordinated operation of the storage bin and the controller achieves the goals of convenient centralized waste collection and easy control. The storage bin provides a convenient method for waste collection, ensuring a clean processing environment; while the controller provides flexibility and precision in equipment operation, enabling the entire processing process to proceed smoothly according to actual needs. The two work together to improve the overall practicality and efficiency of the equipment.

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] refer to Figures 1 to 4 A tapping machine for ductile iron pipe fittings includes a fixed base 1 and a clamping assembly 2. The clamping assembly 2 is fixedly connected to the top of the fixed base 1. The clamping assembly 2 includes an opening of a mounting plate 201, two electric guide rails 202, and two sets of electric sliding blocks 203 slidably connected inside each of the two electric guide rails 202. A device mounting shell 204 is fixedly connected to the top of the two sets of electric sliding blocks 203. A side-mounted servo motor 205 is installed inside the device mounting shell 204. The output end of the side-mounted servo motor 205 is connected via... The coupling 206 is rotatably connected to the rotating shaft 207. The outer ring surface of the rotating shaft 207 away from the coupling 206 is fixedly connected to the rotating mounting plate 208 at equal intervals. The rotating mounting plate 208 has three sliding grooves 209 on its inner wall. Three sliders 211 are fixedly connected inside each of the three sliding grooves 209. Three clamping strips 212 are fixedly installed on the surface of each of the three sliders 211 by a group of fixing bolts 210. Three vertically mounted electric push rods 213 are fixedly connected to one side of each of the three sliders 211.

[0029] A protective component 3 is fixedly connected to the top of the fixed base 1 located on both sides of the two electric guide rails 202. The protective component 3 includes a protective cover 301, a protective door 302 is movably connected to the surface of the protective cover 301, and square holes 303 are located on both the left and right sides of the protective cover 301.

[0030] A vertically mounted hydraulic cylinder 304 is fixedly connected to the upper surface of the inner wall of the protective cover 301. A machining and mounting shell 305 is fixedly connected to the bottom of the vertically mounted hydraulic cylinder 304. A vertically mounted drive motor 306 is fixedly installed inside the machining and mounting shell 305.

[0031] The lower end of the vertically mounted drive motor 306 is rotatably connected to a support shaft 307 via a coupling 206. The lower ring surface of the support shaft 307 is fixedly connected to a tapping mounting plate 308 at equal intervals. The tapping mounting plate 308 is movably connected to a tapping head 309.

[0032] In this embodiment, the electric slider 211 inside the electric guide rail 202 can slide under the control of the controller 7. The movement of the electric slider 211 within the electric guide rail 202 adjusts the position of the device mounting housing 204 and its connected components, adapting to different placement requirements. The side-mounted servo motor 205 inside the device mounting housing 204 operates, driving the rotating shaft 207 to rotate via the coupling 206, thereby causing the rotating mounting plate 208 to rotate. The electric slider 211 within the groove 209 on the inner wall of the rotating mounting plate 208 moves the clamping bar under the control of the controller 7. The movement of the clamping bar clamps the horizontal and vertical connections of the tee pipes placed on one side of the rotating mounting plate 208, firmly securing tee pipes of different sizes for subsequent processing.

[0033] The protective cover 301 of the protective component 3 is fixed to the top of the fixed base 1 on both sides of the two electric guide rails 202, providing protection for the equipment. A vertically mounted hydraulic cylinder 304, fixed to the upper surface of the inner wall of the protective cover 301, drives the machining and mounting shell 305 connected to the bottom to rise and fall through its telescopic movement. Driven by the hydraulic cylinder, the height of the machining and mounting shell 305 is precisely controlled, ensuring that the support shaft 307 and tapping mounting plate 308 connected to the lower end of the vertically mounted drive motor 306 inside the machining and mounting shell 305 accurately reach the position to be processed on the tee pipe. When the vertically mounted drive motor 306 operates, it drives the support shaft 307 to rotate through the coupling 206, thereby causing the tapping mounting plate 308 to rotate. The tapping head 309 movably connected to the tapping mounting plate 308 rotates accordingly, drilling and tapping the tee pipe. Through the coordinated operation of the drive motor and various connecting components, drilling and tapping operations are performed on the tee pipe openings at different positions, achieving the purpose of meeting the processing requirements of the tee pipe.

[0034] Square holes 303 are provided on both sides of the protective cover 301. The user stands on one side of the protective cover 301 and moves the device mounting shell 204 and the processed T-pipe into the square holes 303 by controlling the electric slider 211. This design allows the user to conveniently transport the processed T-pipe from one side of the protective cover 301, thus avoiding the user directly reaching into the interior of the protective cover 301 and reducing safety risks.

[0035] refer to Figure 1 and Figure 2The fixed base 1 has a feeding port 4 on the top and an insertion port 5 on one side. A storage compartment 6 is slidably connected inside the insertion port 5. A controller 7 is fixedly connected to the surface of the fixed base 1.

[0036] In this embodiment, the discharge port 4 at the top of the fixed base 1 guides metal shavings and other waste materials generated during the processing of the T-shaped pipe downwards, achieving the purpose of collecting and concentrating the waste. An insertion port 5 is provided on one side of the fixed base 1, within which the storage bin 6 is slidably connected. When waste falls through the discharge port 4, it enters the storage bin 6. This structural design enables centralized collection of waste generated during processing, facilitating subsequent unified cleaning and disposal. The storage bin 6 can be easily inserted or pulled out through the insertion port 5, allowing operators to conveniently remove it for waste disposal after processing, further demonstrating its convenience in waste collection.

[0037] The controller 7, fixedly connected to the surface of the fixed base 1, serves as the control core of the entire equipment. It connects with various key components such as the electric guide rail 202, electric slider 211, side-mounted servo motor 205, vertically mounted hydraulic cylinder 304, and vertically mounted drive motor 306. Through the controller 7, operators can issue various commands to achieve precise control of these components. For example, the controller 7 can control the movement of the electric slider 211 within the electric guide rail 202, thereby adjusting the position of the clamping assembly 2 to clamp different sized tee pipes; it can also control the extension and retraction of the vertically mounted hydraulic cylinder 304, ensuring that the machining mounting shell 305 and tapping components accurately reach the machining position. This comprehensive and precise control method meets different processing needs and allows for flexible adjustment of the equipment's operating status, making equipment operation more convenient and efficient.

[0038] Working Principle: Before using this device, it must first be installed and debugged. The user needs to install the appropriate tapping drill bit at the bottom of the tapping mounting plate 308 to prepare for subsequent tapping work. By installing the drill bit in the designated position, the necessary processing tool is provided for the processing of tee pipes, enabling the tapping operation of the tee pipes. After completing the drill bit installation, the user turns on the control device through controller 7. Controller 7 enables centralized control of all components of the equipment, allowing the user to accurately operate the equipment according to processing requirements, thereby starting the equipment and putting it into a working state.

[0039] The user stands on one side of the protective cover 301 and controls the electric slider 211 to move within the slide groove 209 via the controller 7. The electric slider 211 is connected to the clamping bar; its movement within the slide groove 209 adjusts the position of the clamping bar, thus initially positioning the tee pipe on one side of the rotating mounting plate 208. Subsequently, the controller 7 again operates the electric slider 211, which drives the vertically mounted electric push rod 213, thereby moving the clamping bar to firmly clamp the horizontal and vertical connections of the tee pipe. This method ensures the stability of the tee pipe during processing, guaranteeing machining accuracy.

[0040] After clamping is completed, the electric slider 211 is controlled by the controller 7. The electric slider 211 drives the device mounting shell 204 to move on the electric guide rail 202, thereby moving the device mounting shell 204 and the clamped T-tube to a position perpendicular to the rotating mounting plate 208. By precisely adjusting the position, the T-tube is placed in a suitable machining position to facilitate subsequent tapping operations.

[0041] After the position is adjusted, the vertically mounted hydraulic cylinder 304, which is fixedly connected to the upper surface of the inner wall of the protective cover 301, is activated. The bottom of the vertically mounted hydraulic cylinder 304 is connected to the machining and mounting shell 305. Through the extension and retraction of the hydraulic cylinder, the machining and mounting shell 305 and the internal vertically mounted drive motor 306, support shaft 307, tapping mounting plate 308, and tapping drill bit are driven to descend, so that the tapping drill bit contacts the first opening of the tee pipe. The vertically mounted drive motor 306 drives the tapping drill bit to rotate, and the first opening of the tee pipe is tapped to achieve the purpose of machining threads on the tee pipe.

[0042] After tapping the first end of the pipe, the side-mounted servo motor 205 inside the mounting housing 204 of the start-up device is activated. The output end of the side-mounted servo motor 205 is connected to the rotating shaft 207 via a coupling 206. The operation of the servo motor drives the coupling 206 and the rotating shaft 207 to rotate 90 degrees, which in turn drives the rotating mounting plate 208 and the tee pipe it holds to rotate, thereby rotating the second end of the tee pipe on the left side to below the tapping drill bit, achieving the purpose of performing the same tapping operation on the second tee pipe end.

[0043] After the second pipe end is tapped, the side-mounted servo motor 205 drives the coupling 206, the rotating shaft 207, and the rotating mounting plate 208 to rotate 180 degrees counterclockwise, so as to rotate the third tee pipe end to the bottom of the tapping drill bit, and tap and drill the third tee pipe end to complete the tapping of the three pipe ends of the tee pipe.

[0044] During the tapping process of the T-joint pipe, metal shavings are generated. The top of the fixed base 1 has a discharge port 4, which collects and guides the metal shavings generated during processing downwards, allowing them to fall in a concentrated manner. One side of the fixed base 1 has an insertion port 5, inside which a storage chamber 6 is slidably connected. The falling shavings enter the storage chamber 6 through the discharge port 4, achieving centralized collection of metal shavings for convenient subsequent unified processing and maintaining a clean working environment.

[0045] After a T-shaped pipe is processed, the controller 7 controls the electric slider 211, which moves the device mounting shell 204 and the processed T-shaped pipe horizontally toward the square hole 303 on one side of the protective cover 301. This horizontal movement moves the processed T-shaped pipe to a position easy to remove, facilitating subsequent retrieval. Subsequently, the vertically mounted electric push rod 213 drives the slider 211 and the clamping strip to release the T-shaped pipe, thus releasing it. This prevents users from directly reaching their hands into the protective cover 301 to retrieve the pipe, preventing injury to workers due to misoperation.

[0046] After all the work is completed, the user pulls out the storage compartment 6 through the insertion port 5 on one side of the fixed base 1, and centrally processes the debris collected in the storage compartment 6 to complete the entire processing flow.

[0047] The above description is merely one or more preferred embodiments of the ductile iron pipe fitting tee tapping machine of this application, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the process of implementing the above embodiments and the equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
