Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tool processing, more particularly, to a built-in motor driven gear hobbing machine tool holder. BACKGROUND

[0002] The gear hobbing machine is a machine tool specially used for processing gears, and is the most widely used in gear processing machine tools. The working principle of the gear hobbing machine is based on the relative movement between the hob and the workpiece. The gear hobbing machine accurately processes the tooth profile of the gear through the rolling cutting mode. The tooth profile of the hob is composed of a set of precise blades, which are matched with the tooth profile of the workpiece to be processed. When the hob rolls along the surface of the workpiece, the tooth profile of the workpiece can be machined. This processing mode not only has high efficiency, but also has high precision and good surface quality, and is the mainstream technology of modern gear processing.

[0003] The hob is usually installed on the tool holder, and the tool holder is adjusted to enable the hob to be flexibly adjusted in position and angle to adapt to different processing requirements. That is, the tool holder can be moved. Compared with the traditional design of completely fixing the tool holder, although the movable tool holder structure provides greater flexibility, it also brings some problems, that is, the tool holder may vibrate during processing. The vibration is caused by incomplete fastening of the tool holder fixing device, insufficient rigidity of the tool holder structure, or dynamic force generated during processing.

[0004] The vibration of the tool holder causes a slight change in the relative position between the hob and the workpiece, which affects the accuracy of the tooth profile. In the processing of precision gears, such a small error can be amplified, resulting in poor meshing of the gear, increased noise, and even affecting the operation performance of the entire mechanical system.

DETAILED DESCRIPTION

[0031] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments, and based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort shall fall within the protection scope of the present application.

[0032] Please refer to Figures 1 to 5 The application discloses a built-in motor-driven gear hobbing machine tool rest, which comprises a mounting seat 1, a rotating disc 2 arranged at the front end of the mounting seat 1, a hobbing cutter 3 arranged at the front end of the rotating disc 2, support plates 4 rotatably arranged at the upper ends of the hobbing cutter 3, the support plates 4 being fixedly connected with the rotating disc 2, a first driving motor 19 arranged on the rotating disc 2 and used for driving the hobbing cutter 3 to rotate, an infeed assembly arranged at the lower end of the mounting seat 1 and used for controlling the infeed force of the hobbing cutter 3, the infeed assembly comprising a lead screw 6, the lead screw 6 being arranged at the lower half of the mounting seat 1, the lead screw 6 extending to the outside through the mounting seat 1 at both ends, the lead screw 6 being in threaded transmission connection with the mounting seat 1, and one end of the lead screw 6 being provided with a second driving motor 5.

[0033] A rotating assembly is arranged at the back of the mounting seat 1 and used for driving the rotating disc 2 to rotate, the rotating assembly comprising a servo motor 9, the servo motor 9 being arranged at the back of the mounting seat 1, a gear 8 being arranged at the output end of the servo motor 9, a rotating shaft 7 being in meshing connection with the outer circle of the gear 8, and one end of the rotating shaft 7 being movably arranged through the mounting seat 1 and fixedly connected with the rotating disc 2.

[0034] A torque sensor 10 is arranged between the first driving motor 19 and the transmission component of the hobbing cutter 3, one group of the support plates 4 is composed of a force receiving plate 41 and a pressure plate 42, and a pressure sensor 12 is arranged between the force receiving plate 41 and the pressure plate 42.

[0035] The range of the infeed force of the hobbing cutter 3 and the torque range value of the first driving motor 19 for driving the hobbing cutter 3 to process a workpiece are set in advance, if the torque value detected by the torque sensor 10 is higher than the preset torque range value, the infeed assembly reduces the infeed force, and if the torque value detected by the torque sensor 10 is lower than the preset torque range value, the infeed assembly increases the infeed force.

[0036] First of all need to explain, the mounting seat 1 of the application is installed at the machining position of the gear hobbing machine, in work, through the second driving motor 5 control screw rod 6 positive and negative rotation, through the positive and negative rotation of the screw rod 6 can control the mounting seat 1 moves left and right, the mounting seat 1 when moving left and right will drive the hob 3 to move left and right, through the left and right movement of the hob 3, can realize the operation of the tooling. When the angle of the hob 3 needs to be adjusted, the gear 8 is controlled to rotate forward and backward by the servo motor 9, the gear 8 will drive the shaft 7 connected with it to rotate forward and backward when rotating forward and backward, the shaft 7 will drive the rotating disc 2 to rotate forward and backward in the process of rotating forward and backward, the rotating disc 2 will drive the hob 3 to rotate in the process of rotating forward and backward, so as to realize the angle adjustment of the hob 3, after adjustment, the servo motor 9 can be locked through program control, to avoid the rotation of the shaft 7 affecting the angle of the hob 3. The first driving motor 19 controls the hob 3 to rotate, and the hob 3 rotates to realize the cutting of the workpiece. When the tooling is carried out, the hob 3 will exert pressure on the workpiece, and through the transmission and interaction of force, the extrusion pressure will be transmitted to the pressure plate 42, and the pressure sensor 12 will detect the force exerted by the pressure plate 42, that is, the tooling force. When the first driving motor 19 drives the hob 3 to rotate, the torque sensor 10 will detect the torque force received by the first driving motor 19. Before work, the range of tooling force is set in advance, which can be obtained according to experiment, in addition, the torque range value of the first driving motor 19 driving the hob 3 to process the workpiece is set according to the output power of the first driving motor 19 when it works stably. When processing the workpiece, if the pressure sensor 12 detects that the tooling force is too large, the movement of the mounting seat 1 is controlled by controlling the positive and negative rotation of the screw rod 6, so as to control the tooling force within a suitable range; when processing the workpiece, if the value detected by the pressure sensor 12 is within the preset tooling force range, and the torque value detected by the torque sensor 10 is lower than the preset torque value, the tooling force can be automatically increased within the preset tooling force range at this time, so as to ensure that the highest processing efficiency can be automatically provided for the workpiece in the stable processing process.

[0037] Figures 1 to 5 If the tooling assembly is adjusted according to the preset tooling force range, and the torque value detected by the torque sensor 10 is not within the preset torque range value, it is determined that the first driving motor 19 and the hob 3 are damaged.

[0038] When the workpiece is processed, if the feed assembly is adjusted within the range of the feed force, if the torque value detected by the torque sensor 10 is not within the preset torque range value, or if the detected torque value range value fluctuates and is unstable, it can be determined that one of the first drive motor 19 and the hob 3 has a problem. For example, when the hob 3 is damaged, its ability to cut the workpiece is greatly reduced, causing the friction during cutting to increase, which can cause the torque sensor 10 to detect an increase in force during the processing of the workpiece, and finally not within the preset torque range value. For example, the first drive motor 19 is damaged, which can cause the torque sensor 10 to detect fluctuations in the value, or the output torque of the first drive motor 19 is too large or too small. Through the detection of the torque sensor 10, it can be determined that one of the first drive motor 19 and the hob 3 is damaged, or both are damaged at the same time, at which time an alarm can be triggered to remind the worker to stop and repair. The alarm can be a sound emitted by a buzzer, or a flashing light, etc., to remind the worker.

[0039] Figures 1 to 5 The front end face of the rotating disc 2 is provided with a vibration sensor 11 near the center position, and the front end face of the mounting seat 1 is also provided with a plurality of stable control assemblies. The stable control assemblies are used to adjust the extrusion force of the rotating disc 2, and the corresponding stable control assemblies are controlled to apply corresponding force to the rotating disc 2 through the detection data of the vibration sensor 11. The stable control assembly is four groups, and the four groups of stable control assemblies are evenly distributed in a ring shape on the outer circular surface of the rotating disc 2. The stable control assembly includes an extrusion plate 13, which is slidingly mounted on the mounting seat 1. The extrusion plate 13 is fixedly connected with an extension column 14 on one side. The extension column 14 is provided with a shell 18 at the end away from the extrusion plate 13. The outer wall of the shell 18 is fixedly connected with the rotating disc 2. The end of the extension column 14 away from the extrusion plate 13 is fixedly connected with a permanent magnet disc 16. The permanent magnet disc 16 is provided with an electromagnet 17 away from the extension column 14. The electromagnet 17 is fixedly connected with the inner wall of the shell 18. The extension column 14 is provided with a spring 15, and the spring 15 is arranged in the shell 18.

[0040] By adopting the above technical solution, after the hob 3 angle is adjusted, the electromagnet 17 can be energized. The electromagnet 17 generates magnetism and applies magnetic repulsion to the permanent magnet 16. The permanent magnet 16 moves away from the electromagnet 17 and compresses the spring 15. At the same time, the telescopic column 14 drives the pressing plate 13 to press the rotating disk 2, which can further lock the rotating disk 2 and reduce the vibration of the hob 3 during processing, thus ensuring the processing quality of the workpiece to a certain extent. It should be noted that after the hob 3 is adjusted, the electromagnet 17 is energized to make the pressing plate 13 apply force to the rotating disk 2. However, only a portion of the force that the electromagnet 17 can output is applied. For example, at maximum power, the electromagnet 17 can make the pressing plate 13 apply a force of 100N to the rotating disk 2. However, after the hob 3 angle is adjusted, the pressing plate 13 only applies a force of 50N to the rotating disk 2. That is to say, the electromagnet 17 only outputs a portion of its power.

[0041] Figures 1 to 5 The weight of the rotating disk 2 and the weight of the components mounted on the rotating disk 2 are determined in advance to obtain the total weight M. The acceleration data of the rotating disk 2 in the X and Y axes at each moment are obtained by the vibration sensor 11. According to Newton's second law... By combining the obtained acceleration data in the X and Y axes and the total weight M, the magnitude of the vibration force of the rotating disk 2 in the X and Y axes is calculated. The direction of the vibration force on the X and Y axes is used to determine the corresponding stabilization component. The purpose is to determine which stabilization component's electromagnet 17 needs to have its current increased.

[0042] The quantitative relationship between the current of the electromagnet 17 in the stabilization component and the compressive force applied by the telescopic column 14 to the outside was determined in advance through experiments. By applying different magnitudes of current to the electromagnet 17 and measuring the compressive force applied by the telescopic column 14 to the outside under the corresponding current, the relationship between the current of the electromagnet 17 and the compressive force applied by the telescopic column 14 to the outside was established. With extrusion pressure The mapping relationship.

[0043] Based on the calculated magnitudes of the vibration forces on the X and Y axes The direction and corresponding stabilization components determine the compressive force that the corresponding stabilization components need to apply to the rotating disk 2. That is to say, the magnitude of the vibration force on the X and Y axes is The corresponding stabilization components also need to apply a force of the same magnitude to the rotating disk 2, and the direction of the force is opposite to the direction of the vibration force. This is to achieve mutual cancellation of the forces, reduce the vibration of the rotating disk 2, thereby improving the stability of the hob 3 during processing and ensuring the processing accuracy of the workpiece.

[0044] After obtaining After the data is collected, it is subjected to extrusion pressure. and current With extrusion pressure The mapping relationship is used to obtain the required current magnitude for the electromagnet 17 within the stabilization component. For example, if the electromagnet 17 was previously energized, causing the pressing plate 13 to apply a force of 50N to the rotating disk 2, and then, due to the vibration of the rotating disk 2, it is calculated that the force applied by the rotating disk 2 on the X-axis is 30N and the force applied on the Y-axis is 20N, then the electromagnet 17 in the stabilization component needs to apply a force of 80N on the X-axis and 80N on the Y-axis of the rotating disk 2.

[0045] Figures 1 to 5 The system records the magnitude and direction of the vibration force along the X and Y axes on the rotating disk 2 at each moment, as well as the corresponding stabilization components. Based on the period of the vibration frequency of the rotating disk 2 and the recorded data, a current of a corresponding magnitude is passed into the corresponding electromagnet 17 before the rotating disk 2 vibrates at the next moment. Through advance prediction, the electromagnet 17 in the stabilization components can apply a suitable magnitude and direction of squeezing force before the rotating disk 2 vibrates at the next moment, accurately counteracting the vibration force that the rotating disk 2 will generate. This more effectively reduces the vibration amplitude of the rotating disk 2, achieves precise control of vibration, greatly shortens the system's response time to vibration, and allows the rotating disk 2 to recover to a stable state more quickly, reducing the adverse effects of vibration on the hob 3.

[0046] Based on the maximum allowable current passing through electromagnet 17 and the current in electromagnet 17 With extrusion pressure The mapping relationship is used to obtain the maximum compressive force exerted by the stabilization component on the outside. The magnitude of the vibration force on the X and Y axes is compared with the maximum compressive force exerted by the stabilization component on the outside. If the vibration force on the X and Y axes is greater than the maximum compressive force exerted by the stabilization component on the outside, it means that the rotating disk 2 vibrates violently during the processing of the hob 3, and the stabilization component can no longer stabilize the rotating disk 2. At this time, an alarm can be triggered to remind the staff to come to the side of the mechanical equipment and stop the machine for maintenance.

[0047] If the vibration force on the X and Y axes is less than the maximum compressive force exerted by the stabilization component on the outside, then a current of the corresponding magnitude is passed through the electromagnet 17, indicating that the device is operating normally at this time.

[0048] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
