A type of gearbox flange processing mold Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a speed reducer flange processing mold. Background Technology

[0002] Flange processing molds, specialized tools for forming flange parts, are widely used in mechanical manufacturing and pipe connection fields. Their core functions include precise shaping, maintaining dimensional stability, improving processing efficiency, and ensuring consistency in mass production. Publication number CN212285936U discloses a flange processing mold, relating to the field of flange processing technology. It includes a base, the left end of which is connected to the bottom of a support plate. The top of the support plate is connected to the bottom left end of a top plate. A telescopic cylinder is mounted on the top plate, with a piston rod inside the cylinder located below the top plate. The piston rod is connected to a limiting component that restricts the workpiece position during processing. A rotating... The motor has its output end connected to a rotating rod, and the top of the rotating rod is connected to a gear assembly that enables the motor to drive multiple shafts to rotate simultaneously. The limiting assembly includes a limiting cylinder connected to the bottom of the piston rod. This invention can simultaneously drill multiple holes required on the flange edge, greatly improving work efficiency and saving the time of drilling holes for a single flange, making it more practical. This invention, by setting up a gear assembly and a piston assembly, can simultaneously drill multiple holes required on the flange edge. However, when dealing with flanges of different sizes, complex surfaces such as inclined surfaces and conical surfaces, and flange double-sided processing scenarios, it cannot rotate the flange processing surface, which requires improvement. Summary of the Invention

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a reducer flange processing mold, including a base, a hydraulic rod fixedly installed on the surface of the base, a cover plate fixedly installed on the output end of the hydraulic rod, a mold groove opened on the surface of the base, a clamping motor fixedly installed on the side of the base, a clamping threaded rod fixedly installed on the output end of the clamping motor, a clamping seat A and a clamping seat B threadedly connected to the surface of the clamping threaded rod, a corner motor fixedly installed on the surface of the clamping seat A, a clamping plate A fixedly installed on the output end of the corner motor, a clamping slide rod fixedly installed on the surface of the clamping plate A, a corner slide rod slidably connected inside the clamping seat B, a clamping plate B fixedly installed at the other end of the corner slide rod, a sliding groove opened on the surface of the clamping plate B, a lifting motor and a lifting slide rod fixedly installed on the bottom surface of the base, a lifting threaded rod fixedly installed on the output end of the lifting motor, and a mold base threadedly connected to the surface of the lifting threaded rod.

[0005] Preferably, both the clamping threaded rod and the lifting threaded rod are bidirectional threaded rods, and the clamping seats A and B are the same size and symmetrically distributed on both sides of the clamping threaded rod. Here, the bidirectional threaded rod can synchronously drive the clamping seats A and B to move towards or away from each other, simplifying the control logic and improving operating efficiency. The symmetrical distribution of clamping seats A and B ensures uniform clamping force applied to the flange, preventing the flange from shifting or deforming due to uneven force, ensuring machining accuracy, preventing dimensional errors caused by improper clamping, ensuring that the form and position tolerances of the reducer flange meet design requirements, and extending the service life of the mold.

[0006] Preferably, there are two clamping slide rods symmetrically distributed on both sides of the clamping plate A. The clamping plate A and clamping plate B are the same shape and size, and the surfaces of the clamping slide rods are slidably connected to the surfaces of the sliding grooves. Here, the clamping slide rods and the sliding grooves of the clamping plate B cooperate to form a stable transmission structure. When the angle motor drives the clamping plate A to rotate, the clamping slide rods accurately transmit the rotational power to the clamping plate B, ensuring that the two clamping plates rotate synchronously, thereby driving the flange to rotate around a fixed axis. By controlling the rotation angle of the angle motor, the flange can be quickly adjusted to the required processing angle without repeatedly disassembling and re-clamping the workpiece, significantly improving the efficiency of inclined surface processing.

[0007] Preferably, the lifting threaded rod and the lifting slide rod are of the same length, and the surface of the lifting slide rod is slidably connected to the interior of the mold base. Here, the lifting threaded rod can drive the mold base to move up and down on the lifting slide rod, which can accurately match flanges of different height specifications. The mold base can be raised to a suitable height by the lifting threaded rod to ensure effective cooperation between the flange and the various components of the mold. When the rotary motor drives the flange to rotate and process inclined surfaces or irregular structures, the mold base can finely adjust its height according to actual processing requirements through the bidirectional threaded rod to place the flange in the optimal processing position, preventing tool collisions or incomplete processing caused by height deviations. This allows the mold to flexibly handle diverse processing tasks, improving production efficiency and processing quality.

[0008] Preferably, a fixing block is fixedly installed on the bottom surface of the cover plate, and a machining head is fixedly installed on the surface of the fixing block via a fixing sleeve. A fixing groove is formed on the surface of the machining head, a fixing screw is threaded into the internal part of the fixing sleeve, and a fixing bolt is threaded into the surface of the fixing screw. This design allows for quick and stable installation of the machining head on the cover plate. When machining different surfaces or bevels of the flange, the original machining head can be easily disassembled simply by loosening the fixing screw and fixing bolt, and a suitable tool can be installed according to the new machining requirements. This avoids the drawbacks of requiring complete disassembly or complex adjustments to replace the tool, shortening tool change time and improving machining efficiency. The cooperative design of the fixing groove and fixing sleeve accurately positions the machining head, ensuring the positional accuracy of the tool after replacement. Combined with the tightening effect of the fixing screw and fixing bolt, it effectively prevents tool loosening during machining, ensuring the dimensional accuracy and surface quality of the flange machining.

[0009] Preferably, the fixed end of the fixing block and the fixed end of the fixing sleeve have the same shape, and the surface of the fixed end of the fixing block, the surface of the fixed end of the fixing sleeve, and the surface of the fixing groove are in close contact. Here, the fixing block, the fixing sleeve, and the fixing groove have the same shape and their surfaces are in close contact, which ensures accurate positioning of the machining head during installation, avoids tool shaking or offset caused by installation deviation, and ensures that the axis of the machining head and the flange to be processed maintain a precise relative position, thereby effectively improving machining accuracy. The close contact of the surfaces also enhances the rigidity of the fixing structure. During processing, the cutting force, vibration, and other external forces on the machining head can be evenly distributed to the cover plate through the contact surface, reducing the stress deformation of the machining head, reducing the machining error caused by vibration, and ensuring the smoothness and flatness of the flange machining surface.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a clamping threaded rod, a corner threaded rod, a lifting threaded rod, and a mold base, the synergistic effect of these structures allows the clamping threaded rod to synchronously drive the symmetrically distributed clamping seats A / B, achieving rapid centering and uniform clamping of the flange, avoiding deformation caused by uneven force. The corner motor precisely controls the synchronous rotation of the clamping plates A / B, allowing the flange to be flexibly adjusted according to a preset angle to meet the processing requirements of multiple angles such as inclined surfaces and bevels. The lifting threaded rod, in conjunction with the lifting slide rod, drives the mold base to rise and fall symmetrically, which can not only adapt to the clamping of flanges of different heights, but also dynamically adjust the processing height when the flange rotates, ensuring that the tool and the workpiece maintain the optimal cutting position. It is suitable for the production of multi-specification, high-precision reducer flanges, providing a solution for the efficient processing of complex workpieces.

[0012] 2. In this utility model, by setting a fixing block, a machining head, a fixing sleeve, and fixing screws, the synergistic effect of these structures allows the fixing block and fixing sleeve to fit tightly together through their matching fixed ends, providing a precise positioning reference for the machining head and ensuring no deviation in the axial position when changing different tools. The nested design of the fixing groove and the fixing sleeve, combined with the double fastening of the fixing screws and fixing bolts, stably locks the machining head to the bottom surface of the cover plate. This not only withstands the impact force during high-speed cutting but also allows for quick disassembly and assembly to switch machining functions. When different surfaces or bevels of the flange need to be machined, the machining head can be quickly changed by loosening the fixing screws without disassembling the overall mold, shortening the tool change time. This not only meets the precision requirements of multi-process machining but also improves the mold's adaptability to diverse machining needs, providing a reliable modular solution for the efficient and precise machining of reducer flanges.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please refer to Figures 1-4. This utility model provides a technical solution: a reducer flange processing mold, including a base 1, which serves as a basic support component for the mold, providing a stable mounting platform for components such as the hydraulic rod 2, mold groove 4, and clamping motor 5, ensuring the stability of the mold structure throughout the processing and preventing the flange processing accuracy from being affected by foundation shaking. The hydraulic rod 2 is fixedly installed on the surface of the base 1, and a cover plate 3 is fixedly installed on the output end of the hydraulic rod 2. A mold groove 4 is opened on the surface of the base 1, and a clamping motor 5 is fixedly installed on the side of the base 1. A clamping threaded rod 6 is fixedly installed on the output end of the clamping motor 5. A clamping seat A7 and a clamping seat B11 are threadedly connected to the surface of the clamping threaded rod 6. Both the clamping threaded rod 6 and the lifting threaded rod 16 are bidirectional threaded rods. The clamping seat A7 and the lifting threaded rod 16 are threaded together. Clamping seats B11 are of the same size and symmetrically distributed on both sides of the clamping threaded rod 6. Here, the bidirectional threaded rod can synchronously drive clamping seats A7 and B11 to move towards or away from each other, simplifying the control logic and improving operating efficiency. The symmetrical distribution of clamping seats A7 and B11 ensures uniform clamping force applied to the flange, preventing the flange from shifting or deforming due to uneven force, ensuring machining accuracy, preventing dimensional errors caused by improper clamping, ensuring that the form and position tolerances of the reducer flange meet design requirements, and extending the service life of the mold. A rotary motor 8 is fixedly installed on the surface of clamping seat A7, and a clamping plate A9 is fixedly installed on the output end of the rotary motor 8. A clamping slide rod 10 is fixedly installed on the surface of clamping plate A9, and a rotary slide rod is slidably connected inside clamping seat B11. 12. A clamping plate B13 is fixedly installed at the other end of the corner slide rod 12. The surface of the clamping plate B13 has a groove 14. There are two clamping slide rods 10 symmetrically distributed on both sides of the clamping plate A9. The clamping plate A9 and the clamping plate B13 are the same in shape and size. The surface of the clamping slide rod 10 is slidably connected to the surface of the groove 14. Here, the clamping slide rod 10 and the groove 14 of the clamping plate B13 cooperate to form a stable transmission structure. When the corner motor 8 drives the clamping plate A9 to rotate, the clamping slide rod 10 accurately transmits the rotational power to the clamping plate B13, ensuring that the two clamping plates rotate synchronously, thereby driving the flange to rotate around the fixed axis. By controlling the rotation angle of the corner motor 8, the flange can be quickly adjusted to the required processing angle without repeated disassembly and reassembly. The workpiece clamping significantly improves the efficiency of inclined surface machining. A lifting motor 15 and a lifting slide rod 18 are fixedly mounted on the bottom surface of the base 1. A lifting threaded rod 16 is fixedly mounted on the output end of the lifting motor 15. A mold base 17 is threadedly connected to the surface of the lifting threaded rod 16. The lifting threaded rod 16 and the lifting slide rod 18 have the same length. The surface of the lifting slide rod 18 is slidably connected to the interior of the mold base 17. Here, the lifting threaded rod can drive the mold base 17 to move up and down on the lifting slide rod 18, accurately matching flanges of different heights. The mold base 17 can be lifted to a suitable height via the lifting threaded rod 16, ensuring effective cooperation between the flange and all components of the mold. When the angle motor 8 drives the flange to rotate and machine inclined surfaces or irregular structures, the mold base 17 can be adjusted according to actual machining requirements.By finely adjusting the height using a two-way threaded rod, the flange is positioned for optimal machining, preventing tool collisions or incomplete machining caused by height deviations. This allows the mold to flexibly handle diverse machining tasks, improving production efficiency and machining quality.

[0024] Example 2

[0025] Please refer to Figure 5. A fixing block 19 is fixedly installed on the bottom surface of the cover plate 3, providing a mounting base for the processing head 20. Its fixing end fits the shape of the fixing sleeve 22 and the fixing groove 21, ensuring accurate positioning of the processing head 20 during installation and guaranteeing the precise position of the axis of the processing head 20 relative to the flange to be processed, thereby improving processing accuracy. The surface of the fixing block 19 is fixedly mounted with the processing head 20 through the fixing sleeve 22. The fixing sleeve 22, the fixing block 19, and the fixing groove 21 fit tightly together to position and fix the processing head 20. Its internal thread design is compatible with the fixing screw 23 and the fixing bolt 24. The machining head 20 can be securely installed to prevent it from loosening during cutting, ensuring machining accuracy and safety. A fixing groove 21 is provided on the surface of the machining head 20, and a fixing screw 23 is threaded inside the fixing sleeve 22. A fixing bolt 24 is threaded on the surface of the fixing screw 23. This allows for quick and secure installation of the machining head 20 onto the cover plate 3. When machining different faces or bevels of the flange, simply loosen the fixing screw 24 and the fixing bolt 23 to easily disassemble the original machining head 20 and replace it with a suitable tool according to the new machining requirements, avoiding the need for complete disassembly or complex adjustments. This design overcomes the drawbacks of tool replacement, shortens tool change time, and improves processing efficiency. The matching design of the fixing groove 21 and the fixing sleeve 22 can accurately position the machining head 20, ensuring the positional accuracy of the tool after replacement. Combined with the tightening effect of the fixing screw 23 and the fixing bolt 24, it can effectively prevent tool loosening during processing, ensuring the dimensional accuracy and surface quality of the flange machining. The fixing end of the fixing block 19 and the fixing end of the fixing sleeve 22 have the same shape, and the surfaces of the fixing ends of the fixing block 19 and the fixing sleeve 22 are in contact with the surfaces of the fixing groove 21. Here, the fixing block 19 and the fixing sleeve 22... The three parts, including the fixed groove 21, have the same shape and fit tightly together, which ensures that the machining head 20 is accurately positioned during installation, avoids tool shaking or displacement caused by installation deviation, and ensures that the axis of the machining head 20 and the flange to be processed maintain a precise relative position, thereby effectively improving the machining accuracy. The tightly fitted surface can also enhance the rigidity of the fixed structure. During the processing, the cutting force, vibration and other external forces on the machining head 20 can be evenly distributed to the cover plate 3 through the fitting surface, reducing the stress deformation of the machining head 20, reducing the machining error caused by vibration, and ensuring the smoothness and flatness of the flange processing surface.

[0026] Working principle: When dealing with flanges of different sizes, complex surfaces such as inclined surfaces and conical surfaces, and flange double-sided processing scenarios, when it is necessary to rotate the flange processing surface, the lifting motor 15 is started according to the flange size, and the lifting threaded rod 16 precisely adjusts the height of the mold base 17 to make the flange and mold components fit together. The clamping motor 5 controls the clamping threaded rod 6 to rotate, driving the clamping seats A7 and B11 to move towards each other, clamping and fixing the flange in the mold groove 4. The angle motor 8 is started to drive the clamping plate A9 to rotate, and the clamping slide rod 10 makes the clamping plate B13 rotate synchronously, thereby driving the flange to rotate around the fixed axis to the required processing angle. If it is necessary to replace the processing head 20, loosen the fixing screws 23 and fixing bolts 24, quickly disassemble the original processing head 20, replace it with a suitable tool, and then tighten it again. This allows the flange to be processed on different surfaces or with different inclinations, realizing the flange multi-scenario and high-precision processing needs.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
