Description

Technical Field

[0001] This utility model belongs to the field of face gear processing technology, specifically relating to a horizontal CNC worm gear grinding machine for face gears. Background Technology

[0002] Face gears are a novel type of gear structure. When combined with spur gears, they form gear pairs used for power transmission between intersecting or staggered shafts. Their unique tooth surface shape gives them advantages such as a large transmission ratio, good interchangeability, and excellent torque distribution performance. This reduces the number of stages in traditional systems, significantly lowers the weight of the transmission system, and increases power density. Furthermore, face gear drives offer strong flexibility and adaptability, suitable for transmission applications with arbitrary axis angles. Face gear drives have wide applications in industries such as aerospace, weaponry, and automotive.

[0003] Currently, there are two main types of face gear finishing: disc wheel grinding and worm wheel grinding. These two grinding methods differ in their grinding principles, machine tool structures, and motion principles. When finishing face gears using cylindrical gear and worm wheel grinding, not only are the travels of each motion axis of the machine tool relatively large, but the overall machine tool size is also large, and the running time of each linear axis is long. Secondly, before grinding face gears, the grinding wheel needs to be dressed. Dressing requires the grinding wheel head to be oscillated as a whole, and only one oscillation angle can be used for dressing, followed by another oscillation and dressing, resulting in low dressing efficiency. Furthermore, before grinding face gears, tool setting is required, currently done manually. This tool setting accuracy is low, and in mass production, the consistency of tool setting for each workpiece is low, leading to problems in mass production. The consistency of part dimensions is difficult to guarantee; furthermore, after grinding face gears, tooth surface accuracy inspection is required. Cylindrical gear and worm gear grinding machines do not have on-machine inspection functions for face gear teeth, requiring the parts to be disassembled and measured offline, affecting processing efficiency; finally, after the face gear tooth surface measurement is completed, grinding wheel dressing parameters need to be calculated offline based on the measurement results to generate the latest grinding wheel dressing program, which is then input into the machine tool to dress the grinding wheel before grinding. In summary, the current face gear grinding equipment has a complex overall process, low efficiency, and cannot guarantee accuracy. Utility Model Content

By integrating the spindle unit, measuring device, tool setting device, and dressing device onto a single machine tool, and coordinating with a lifting assembly and a lateral movement device, this gear grinding machine enables continuous and efficient finishing of face gears, reducing the time spent transferring face gears between different machines and improving production efficiency. Simultaneously, the coordinated operation of the spindle unit, measuring device, and tool setting device ensures high precision during processing. In particular, the measuring device monitors processing accuracy in real time, while the tool setting device ensures precise alignment between the grinding wheel and the face gear, guaranteeing high precision and quality of the machined face gears. The lifting assembly and lateral movement device allow the gear grinding machine to adjust the positions of the workpiece and grinding wheel according to different processing requirements, increasing processing flexibility and adaptability.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0051] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0052] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0054] Currently, there are two main types of face gear finishing: disc wheel grinding and worm wheel grinding. These two grinding methods differ in their grinding principles, machine tool structures, and motion principles. When finishing face gears using cylindrical gear and worm wheel grinding, not only are the travels of each motion axis of the machine tool relatively large, but the overall machine tool size is also large, and the running time of each linear axis is long. Secondly, before grinding face gears, the grinding wheel needs to be dressed. Dressing requires the grinding wheel head to be oscillated as a whole, and only one oscillation angle can be used for dressing, followed by another oscillation and dressing, resulting in low dressing efficiency. Furthermore, before grinding face gears, tool setting is required, currently done manually. This tool setting accuracy is low, and in mass production, the consistency of tool setting for each workpiece is low, leading to problems in mass production. The consistency of part dimensions is difficult to guarantee; furthermore, after grinding face gears, tooth surface accuracy inspection is required. Cylindrical gear and worm gear grinding machines do not have on-machine inspection functions for face gear teeth, requiring the parts to be disassembled and measured offline, affecting processing efficiency; finally, after the face gear tooth surface measurement is completed, grinding wheel dressing parameters need to be calculated offline based on the measurement results to generate the latest grinding wheel dressing program, which is then input into the machine tool to dress the grinding wheel before grinding. In summary, the current face gear grinding equipment has a complex overall process, low efficiency, and cannot guarantee accuracy.

[0055] To address the aforementioned technical deficiencies, the inventors have provided a horizontal CNC worm gear grinding machine for face gears.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings: Figures 1-15 As shown, this utility model embodiment provides a horizontal CNC worm gear grinding machine for face gears, including a base 8, as shown in the figure. Figure 1 and Figure 2As shown, the base 8 includes a first base 806 and a second base, which are axially perpendicular to each other. The lateral movement device includes a first lateral movement component and a second lateral movement component. The first lateral movement component is located on the top of the first base 806 and is used to drive the spindle device 2, measuring device 3, and tool setting device 4 to move. The second lateral movement component is located on the second base, and the workpiece headstock 5 and dressing device 6 are mounted on the second lateral movement component. The second lateral movement component is used to drive the workpiece headstock 5 and tool setting device 4 to move on the second base. A lifting component 1 is installed on the top of the first lateral movement component. The spindle device 2, measuring device 3, and tool setting device 4 are connected to the lifting component 1, and the lifting component 1 is used to drive the spindle device 2, measuring device 3, and tool setting device 4 to move up and down. When machining the face gear 504, the workpiece headstock 5 is used to mount the face gear 504. Then, the spindle device 2, measuring device 3, tool setting device 4, and dressing device 6 sequentially machine the face gear 504 according to the preset operation sequence. During the machining process, by integrating the spindle device 2, measuring device 3, tool setting device 4, and dressing device 6 onto the same machine tool, and cooperating with the lifting assembly 1 and the transverse movement device, the horizontal CNC worm gear grinding machine can perform continuous and efficient finishing operations on the face gear 504. This reduces the time spent transferring the face gear 504 between different machines and improves production efficiency. Simultaneously, the cooperation between the spindle device 2, measuring device 3, and tool setting device 4 ensures high precision during machining. In particular, the measuring device 3 can monitor machining accuracy in real time, while the tool setting device 4 ensures precise alignment, thus guaranteeing that the machined face gear 504 has high precision and quality. Furthermore, the lifting assembly 1 and the transverse movement device allow the grinding machine to adjust the position of the workpiece and workpiece headstock 5 according to different machining requirements, increasing machining flexibility and adaptability. This enables the machine tool to process face gears 504 of different sizes and shapes, meeting diverse production needs. Finally, the measuring device 3 can measure the gear teeth after the face gear 504 has been ground without disassembling the workpiece. The machine tool automatically generates a dressing program based on the measurement results, performs dressing, and then performs gear grinding, improving processing efficiency, processing accuracy, and batch processing dimensional consistency. Figure 1 and Figure 2As shown, the measuring device 3 and the tool setting device 4 are positioned on top of the spindle assembly 2, with the measuring device 3 located above the tool setting device 4. This allows for rapid measurement of the face gear 504 before machining, followed immediately by tool setting, reducing the time spent transferring the workpiece between different devices and improving machining efficiency. The workpiece headstock 5 and the dresser device 6 are positioned at one end and the other end of the transverse traverse device, respectively, with the spindle assembly 2 and the workpiece headstock 5 and dresser device 6 being axially perpendicular. The tool setting device 4 follows closely behind the measuring device 3, ensuring that the measurement data is fully utilized during tool setting to achieve precise alignment of the face gear 504, ensuring machining accuracy and quality. Positioning the measuring device 3 and the tool setting device 4 on top of the spindle assembly 2, while the workpiece headstock 5 and the dresser device 6 are located at opposite ends of the transverse traverse device, optimizes the use of machine tool space.

[0057] like Figure 4 As shown, the spindle assembly 2 includes a spindle box 202 and a main motor 203. The spindle box 202 cooperates with the lifting assembly 1. A grinding wheel 201 is mounted on one end of the spindle box 202, and the other end is connected to the main motor 203. The drive end of the main motor 203 is fixedly connected to the grinding wheel 201. The fixed connection between the drive end of the main motor 203 and the grinding wheel 201 through the spindle box 202 ensures efficient power transmission. The power generated by the main motor 203 can be directly and stably transmitted to the grinding wheel 201, reducing energy loss and improving processing efficiency. Figure 5 As shown, the workpiece headstock 5 includes a headstock housing 501, which is vertically mounted on top of the second transverse moving assembly. A rotary table 502 is located on the side of the headstock housing 501 facing the dressing device 6. A fixture 503 is mounted on top of the rotary table 502, and a face gear 504 is mounted on the fixture 503. During this process, the vertical mounting of the headstock housing 501 on top of the second transverse moving assembly provides stable support for the machining of the face gear 504, ensuring the stability and reliability of the workpiece headstock 5 during machining, helping to reduce vibration and errors, and improve machining accuracy. The rotary table 502 allows the fixture 503 and the face gear 504 mounted on it to rotate within a certain range, adapting to machining requirements at different angles. Multiple angle machining can be achieved without changing the fixture or adjusting the machine tool, improving machining efficiency and flexibility.

[0058] like Figure 6As shown, the dresser device 6 includes a dresser housing 604, which is also vertically mounted on top of the second transverse moving assembly. A dresser rotary support 603 is mounted on the top of the dresser housing 604, and a dresser 602 is mounted on the top of the dresser rotary support 603. A diamond roller 601 is mounted at the end of the dresser 602. The arrangement of the dresser rotary support 603 allows the dresser 602 and the diamond roller 601 to rotate within a certain range. This flexibility allows the dresser to adapt to different angle dressing requirements, achieving dressing at multiple angles without changing tooling or adjusting the machine tool, thus improving dressing efficiency and flexibility. Figure 3 As shown, in this scheme, the lifting assembly 1 includes a column 102, which cooperates with the first transverse moving assembly. The column 102 is located on the top of one end of the first base 806. The column 102 has a movable compartment on one side where the spindle device 2 is located. A first motor 101 is installed on the top of the column 102. The drive end of the first motor 101 extends into the movable compartment and is connected to a first lead screw 104. The first lead screw 104 cooperates with the spindle device 2. Through the effective drive of the first motor 101, the first lead screw 104 can effectively drive the spindle box 202 to move up and down. At the same time, a first guide rail 103 and a second guide rail 105 are also provided on the side of the column 102 where the movable compartment is located. The first guide rail 103 and the second guide rail 105 also cooperate with the spindle box 202 to ensure the smooth sliding of the spindle box 202.

[0059] like Figure 7 As shown, the first lateral component includes a second motor 801, a third guide rail 804, and a fourth guide rail 805. The second motor 801 is mounted on a first motor base 802, which is disposed on a first base 806. A second lead screw 803 is provided at one end of the first motor base 802. The third guide rail 804 and the fourth guide rail 805 are disposed at one end and the other end of the first base 806, respectively. The second lateral movement component includes a third motor base 810, a fifth guide rail 807, and a sixth guide rail 808. The third motor base 810 is mounted on the top of the second base. A third motor 811 is connected to one end of the third motor base 810, and a third lead screw 809 is connected to the other end. The fifth guide rail 807 and the sixth guide rail 808 are disposed at one end and the other end of the top of the second base, respectively.

[0060] The movement principle of each motion axis: X-axis: the first motor 101 drives the first lead screw 104 to rotate, thereby dragging the main spindle device 2 to move up and down along the first guide rail 103 and the second guide rail 105; Y-axis: the second motor 801 provides power to drive the second lead screw 803 to rotate, thereby dragging the column 102 to move back and forth along the third guide rail 804 and the fourth guide rail 805; Z-axis: the third motor 811 provides power to drive the third lead screw 809 to rotate, thereby dragging the worktable 7 to move left and right along the fifth guide rail 807 and the sixth guide rail 808; A-axis: the rotary support 603 rotates along the X-axis under the drive of the built-in motor; B-axis: the grinding wheel 201 rotates along the Y-axis under the drive of the main motor 203; B1-axis: the diamond roller 601 rotates along the Y-axis under the drive of the built-in motor; C-axis: the face gear 504 rotates along the Z-axis under the drive of the built-in motor.

[0061] When the horizontal CNC worm gear grinding machine processes the face gear 504, the process begins with the installation of the face gear 504, followed by the dressing of the grinding wheel 201, automatic tool setting, gear grinding, online measurement, and further dressing and grinding of the grinding wheel 201. The face gear 504 is connected to the rotary table 502 via tooling 503. During the dressing of the grinding wheel 201, the X-axis moves to a position where the B-axis and B1-axis are at the same height and is fixed. The X-axis, B-axis, and B1-axis rotate at a set speed, while the Y-axis, Z-axis, and A-axis move in tandem. The Y-axis moves axially along the grinding wheel 201, the Z-axis moves radially along the grinding wheel 201, and the A-axis oscillates along the dressing contour. Figures 8-10As shown, the probe of the automatic tool setting device 4 extends along the Y-axis, moves the X-axis to a position where the axis of the automatic tool setting probe and the axis of the face gear 504 are aligned and then fixed, moves the Y-axis to a position where the automatic tool setting probe reaches the required position and then fixed, moves the Z-axis to a position where the automatic tool setting probe reaches the required position and then fixed, and then, through the rotational motion of the face gear 504, the probe of the automatic tool setting device 4 finds the starting position on the face gear 504 that needs to be machined. During gear grinding, the B and C axes rotate at a set speed. The face gear 504 moves along the Z-axis to reach the Z-axis machining start point. The grinding wheel 201 moves along the X-axis, machining from the outer diameter of the face gear 504 towards the inner diameter. During machining, the grinding wheel 201 moves along the Y-axis in a linked motion. When the grinding wheel 201 moves along the X-axis to within the inner diameter of the face gear 504, the face gear 504 moves along the Z-axis closer to the grinding wheel 201 by a set dimension. The grinding wheel 201 then machines from the inner diameter of the face gear 504 towards the outer diameter along the X-axis. After the grinding wheel 201 leaves the outer diameter of the face gear 504, the previous machining process is repeated until the face gear 504 reaches the final set position along the Z-axis, completing the grinding. During online measurement, the measuring head of the measuring device 3 extends along the Y-axis and measures the ground face gear tooth surface through the combined movement of the X, Y, and Z axes. Based on the measurement results, the grinding wheel dressing data is adjusted and fed back to the machine tool CNC system. When dressing a grinding wheel, such as Figures 11-15 As shown, the grinding wheel 201 is dressed again according to the latest dressing data of the measuring device 3. Finally, the above grinding process is repeated until the face gear 504 is ground to the finished size.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
