Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC milling machines, specifically a high-precision CNC roll thread milling machine. Background Technology
[0002] A roll thread milling machine is a milling machine specifically designed to machine grooves on the surface of rolls. It performs operations such as grooving and cutting on the surface of rolls using a milling cutter. It can meet the high requirements for the complexity and precision of the grooves on the roll surface. Roll thread milling machines have higher machining accuracy and efficiency, resulting in consistent thread groove dimensions and high surface finish. They are widely used in industries such as steel, metallurgy, and machinery manufacturing.
[0003] The existing equipment has the following shortcomings when in use: high-precision CNC roll thread milling machines generate a lot of waste chips during processing. If these waste chips are not cleaned in time, they are easy to accumulate in the working area of the milling machine, which not only affects the processing accuracy and reduces the service life of the equipment, but also makes the cleaning work of the staff inconvenient and increases the workload. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision CNC roll thread milling machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision CNC roll thread milling machine, comprising a milling machine body, an X-axis moving structure, a Y-axis moving structure, and an adjusting moving structure. A rotating chuck and a fixed chuck are mounted on the milling machine body. The adjusting moving structure in the milling machine body is connected to the fixed chuck. An X-axis moving structure is provided on the milling machine body, and a transverse plate is connected to and mounted on the X-axis moving structure. A Y-axis moving structure is provided on the transverse plate, and a mounting base is mounted on the Y-axis moving structure. An angle plate is mounted on the top of the mounting base. The power shaft of an adjusting motor mounted in the mounting base is connected to the angle plate. An electric telescopic rod is mounted on the angle plate, and a first set of milling cutter structures is mounted on the top of the electric telescopic rod. A chip baffle is mounted on the mounting base, and a chip collection groove is formed on the table surface of the milling machine body.
[0006] Using the above technical solution, the roll to be processed is placed between a rotating chuck and a fixed chuck using hoisting equipment. The adjusting and moving structure is activated, causing the fixed chuck to move towards one end of the roll until both the fixed and rotating chucks clamp and fix the roll. After clamping and fixing the roll, a stepper motor is started to rotate the rotating chuck, allowing the roll to rotate smoothly during milling. The X-axis moving structure moves the milling cutter structure left and right to process the roll. The Y-axis moving structure moves the milling cutter structure back and forth, adjusting the distance between the milling cutter structure and the roll to accommodate the processing needs of rolls with different diameters. The adjusting motor drives the angle plate to rotate, thereby adjusting the processing angle of the milling cutter structure to accommodate the processing needs of rolls with different shapes. The telescopic movement of the electric telescopic rod is used to adjust the height of the milling cutter structure to ensure processing results. The CNC control panel precisely controls the coordinated movements of the X-axis and Y-axis moving structures, the adjusting motor, and the electric telescopic rod, enabling flexible adjustment of the milling path to ensure machining accuracy. When the Y-axis moving structure moves the milling cutter on the mounting base closer to the roll, the chip baffle mounted on the mounting base also moves forward to below the roll. Chips generated during machining are blocked by the chip baffle and guided by its sloping shape, falling into the chip collection trough. After machining is complete, the chips can be discharged through the discharge port. The chip baffle design prevents chips from accumulating in the milling machine's working area, maintaining a clean working environment and avoiding interference with machining accuracy. The chip collection trough facilitates the unified collection and processing of chips, making subsequent cleaning easier and providing convenience for workers.
[0007] Preferably, the X-axis moving structure, Y-axis moving structure, and adjusting moving structure include a drive motor, a lead screw, and a ball nut.
[0008] By adopting the above technical solution, the drive motor drives the lead screw to rotate in both directions, thereby causing the ball nut to move back and forth on the lead screw, realizing the movement of the X-axis movement structure, Y-axis movement structure and adjustment movement structure. This improves the stability and accuracy of the movement structure, and also ensures that the milling cutter structure can accurately reach the designated position during the processing, thus meeting the accuracy requirements for roll processing.
[0009] Preferably, the transverse plate is provided with a second set of milling cutter structures, the second set of milling cutter structures having the same moving structure as the first set of milling cutter structures but different milling cutter discs.
[0010] Using the above technical solution, the second set of milling cutter structures can also achieve flexible movement and positioning in different directions and angles through the coordinated control of the X-axis movement structure, Y-axis movement structure, adjustment motor and electric telescopic rod, so as to adapt to the processing requirements of different rolls. The milling cutter discs of the two sets of milling cutter structures are different, which can perform different forms of milling on the rolls, increasing the processing function and flexibility of the equipment. The alternating use of the first set of milling cutter structures and the second set of milling cutter structures can greatly improve processing efficiency, meet the needs of different processing tasks, and reduce the downtime during tool changing, further improving the overall processing efficiency.
[0011] Preferably, the milling machine body has a discharge port, which is connected to a waste chip collection trough.
[0012] The above technical solution allows the waste material to be discharged smoothly from the waste material collection tank, making it convenient for workers to carry out cleaning work.
[0013] Preferably, the rotating chuck is driven by a stepper motor.
[0014] Using the above technical solution, the stepper motor drives the rotating chuck to rotate, so that the roll can rotate smoothly during the milling process.
[0015] Preferably, a CNC operation panel is installed on the milling machine body, and the PLC controller in the CNC operation panel is connected to the electrical equipment of the milling machine.
[0016] Using the above technical solution, the operator inputs control commands to the PLC controller through the CNC operation panel. After receiving the commands, the PLC controller precisely controls the electrical equipment of the milling machine, realizing the automation and intelligent control of the milling process.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. When the Y-axis moving structure moves the milling cutter structure on the mounting base closer to the roll, the waste chip baffle installed on the mounting base also moves forward to below the roll. Waste chips generated during processing fall into the waste chip collection trough under the obstruction of the waste chip baffle and the guiding effect of the sloping shape of the waste chip baffle. After processing is completed, the waste chips can be discharged through the discharge port. The design of the waste chip baffle prevents the waste chips generated during processing from accumulating in the milling machine working area, keeping the working environment clean and avoiding the problem of waste chip accumulation interfering with the processing process and affecting the processing accuracy. The setting of the waste chip collection trough facilitates the unified collection and treatment of waste chips, making subsequent cleaning easier and providing convenience for the staff.
[0019] 2. By setting two sets of milling cutter discs with different milling cutter structures, different forms of milling processing can be performed on the rolls, increasing the processing function and flexibility of the equipment. The alternating use of the first set of milling cutter structures and the second set of milling cutter structures can greatly improve processing efficiency, meet the needs of different processing tasks, and at the same time reduce the downtime generated during tool changing, further improving the overall processing efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figure 1-4This utility model provides an embodiment of a high-precision CNC roll thread milling machine, comprising a milling machine body 1, an X-axis moving structure 4, a Y-axis moving structure 6, and an adjusting moving structure 14. A rotating chuck 2 and a fixed chuck 3 are mounted on the milling machine body 1. The adjusting moving structure 14 in the milling machine body 1 is connected to the fixed chuck 3.

An electric telescopic rod 10 is mounted on the angle plate 9, and a first set of milling cutter structures 11 is mounted on the top of the electric telescopic rod 10. A waste chip baffle 12 is mounted on the mounting base 7, and a waste chip collection groove 15 is formed on the table surface of the milling machine body 1. The roll to be processed is placed between the rotating chuck 2 and the fixed chuck 3 using hoisting equipment. The adjusting moving structure 14 is activated, causing the fixed chuck 3 to move towards one end of the roll until the fixed chuck 3 and the rotating chuck 2 clamp and fix the roll. After clamping and fixing the roll, the stepper motor is activated to rotate the rotating chuck 2, ensuring smooth rotation of the roll during milling. The X-axis moving structure 4 moves the milling cutter structure left and right to process the roll. The Y-axis moving structure 6 moves the milling cutter structure back and forth to adjust the distance between the milling cutter structure and the roll, adapting to the processing requirements of rolls with different diameters. The adjusting motor 8 drives the angle plate 9 to rotate, thereby adjusting the processing angle of the milling cutter structure to adapt to the processing requirements of rolls with different shapes. The telescopic movement of the electric telescopic rod 10 is used to adjust the height of the milling cutter structure to ensure processing effect. The CNC operation panel 17 is used for precision machining. The coordinated action of the X-axis moving structure 4, Y-axis moving structure 6, adjusting motor 8, and electric telescopic rod 10 is precisely controlled to achieve flexible adjustment of the milling path and ensure machining accuracy. When the Y-axis moving structure 6 drives the milling cutter structure on the mounting base 7 to approach the roll, the waste chip baffle 12 installed on the mounting base 7 also moves forward to below the roll. The waste chips generated during the machining process fall into the waste chip collection trough 15 under the obstruction of the waste chip baffle 12 and the guiding action of the inclined waste chip baffle 12. After the machining is completed, the waste chips can be discharged through the discharge port 16. The design of the waste chip baffle 12 prevents the waste chips generated during the machining process from accumulating in the milling machine working area, keeping the working environment clean and avoiding the problem of waste chip accumulation interfering with the machining process and affecting machining accuracy. The setting of the waste chip collection trough 15 facilitates the unified collection and treatment of waste chips, making subsequent cleaning easier and providing convenience for the staff.
[0027] The X-axis moving structure 4, Y-axis moving structure 6, and adjusting moving structure 14 include a drive motor, a lead screw, and a ball nut. The drive motor drives the lead screw to rotate in both directions, which in turn drives the ball nut to move back and forth on the lead screw, realizing the movement of the X-axis moving structure 4, Y-axis moving structure 6, and adjusting moving structure 14. This improves the stability and accuracy of the moving structure and ensures that the milling cutter structure can accurately reach the designated position during the machining process, thereby meeting the accuracy requirements for roll machining.
[0028] The transverse plate 5 is equipped with a second set of milling cutter structures 13. The second set of milling cutter structures 13 has the same moving structure as the first set of milling cutter structures 11, but with different milling cutter discs. The second set of milling cutter structures 13 can also achieve flexible movement and positioning in different directions and angles through the coordinated control of the X-axis moving structure 4, the Y-axis moving structure 6, the adjusting motor 8, and the electric telescopic rod 10, so as to adapt to the processing requirements of different rolls. The different milling cutter discs of the two sets of milling cutter structures can perform different forms of milling on the rolls, increasing the processing function and flexibility of the equipment. The alternating use of the first set of milling cutter structures 11 and the second set of milling cutter structures 13 can greatly improve processing efficiency, meet the needs of different processing tasks, and reduce downtime during tool changing, further improving the overall processing efficiency.
[0029] The milling machine body 1 is provided with a discharge port 16, which is connected to the waste chip collection tank 15. The design of the discharge port 16 allows waste chips to be discharged smoothly from the waste chip collection tank 15, facilitating cleaning work by the staff.
[0030] The rotating chuck 2 is driven by a stepper motor. The stepper motor drives the rotating chuck 2 to rotate, so that the roll can rotate smoothly during the milling process.
[0031] A CNC operation panel 17 is mounted on the milling machine body 1. The PLC controller installed on the CNC operation panel 17 is connected to the electrical equipment of the milling machine. The operator inputs control commands to the PLC controller through the CNC operation panel 17. After receiving the commands, the PLC controller precisely controls the electrical equipment of the milling machine, realizing the automation and intelligent control of the milling process.
[0032] The control module and electrical components used in the milling machine involved in this application are all existing mature technologies, with many products on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional use. The protection content of this application does not involve improvements to the control module and electrical components used in the milling machine. Therefore, the models of the electrical components used in the milling machine and the control flow of the control system will not be described in detail here. The motor equipment in this application is equipped with a circuit controller and a brake mechanism. The circuit controller allows the motor to flexibly adjust the rotation direction and rotation angle according to actual operation requirements, significantly improving the operational flexibility and safety performance of the equipment. The brake mechanism reliably locks the position when the motor stops, preventing accidental displacement caused by inertia and ensuring the stability and safety of the device in the stopped state.
[0033] Working Principle: The roll to be processed is placed between the rotating chuck 2 and the fixed chuck 3 using a hoisting device. The adjusting moving structure 14 is activated, causing the fixed chuck 3 to move towards one end of the roll until the fixed chuck 3 and the rotating chuck 2 together clamp and fix the roll. After clamping and fixing the roll, a stepper motor is started to drive the rotating chuck 2 to rotate, allowing the roll to rotate smoothly during milling. The X-axis moving structure 4 moves the milling cutter structure left and right to perform the milling operation on the roll. The Y-axis moving structure 6 moves the milling cutter structure back and forth to adjust the distance between the milling cutter structure and the roll to accommodate different milling operations. To meet the processing requirements of rolls with different diameters, the adjusting motor 8 drives the angle plate 9 to rotate, thereby adjusting the processing angle of the milling cutter structure to adapt to the processing needs of rolls with different shapes. The telescopic movement of the electric telescopic rod 10 is used to adjust the height of the milling cutter structure to ensure the processing effect. The coordinated action of the X-axis moving structure 4, Y-axis moving structure 6, adjusting motor 8, and electric telescopic rod 10 is precisely controlled by the CNC operation panel 17 to achieve flexible adjustment of the milling path and ensure processing accuracy. When the Y-axis moving structure 6 moves the milling cutter structure on the mounting base 7 closer to the roll, the chip baffle 12 installed on the mounting base 7 also moves forward. Below the rolls, the waste chips generated during processing fall into the waste chip collection trough 15 under the obstruction of the waste chip baffle 12 and the guiding effect of the sloping shape of the waste chip baffle 12. After processing is completed, the waste chips can be discharged through the discharge port 16. The design of the waste chip baffle 12 prevents the waste chips generated during processing from accumulating in the milling machine working area, maintaining a clean working environment and avoiding the problem of waste chip accumulation interfering with the processing process and affecting processing accuracy. The setting of the waste chip collection trough 15 facilitates the unified collection and treatment of waste chips, making subsequent cleaning easier and providing convenience for the staff. The second set of milling cutters Structure 13 can also achieve flexible movement and positioning in different directions and angles through the coordinated control of X-axis moving structure 4, Y-axis moving structure 6, adjusting motor 8, and electric telescopic rod 10, so as to adapt to the processing requirements of different rolls. The milling cutter discs of the two sets of milling cutter structures are different, which can perform different forms of milling on the rolls, increasing the processing function and flexibility of the equipment. The alternating use of the first set of milling cutter structures 11 and the second set of milling cutter structures 13 can greatly improve the processing efficiency, meet the needs of different processing tasks, and reduce the downtime during tool changing, further improving the overall processing efficiency.
