[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-4 This utility model provides an embodiment of a worm gear machining integrated machine tool, including a machine base 1. Two symmetrically distributed primary bearing seats 2 are fixedly installed on both sides of the upper surface of the machine base 1. A lead screw 3 is rotatably connected between the two primary bearing seats 2. A transverse slide plate 5 is threadedly connected to the external of the lead screw 3. One end of the lead screw 3 is fixedly connected to the output shaft of a motor 4. Therefore, when the motor 4 is working, it can drive the lead screw 3 to rotate clockwise or counterclockwise through the output shaft. When the lead screw 3 rotates in both directions, the transverse slide plate 5 threadedly connected to it can move laterally left and right along the lead screw 3. This is the X-axis threaded transmission structure of the machine tool.

[0027] Furthermore, symmetrically distributed secondary bearing seats 6 are fixedly installed at both ends of the transverse slide plate 5. A second lead screw 7 is rotatably connected between the two secondary bearing seats 6. The second lead screw 7 is perpendicular to the first lead screw 3. The external thread of the second lead screw 7 is connected to the longitudinal slide plate 9. One end of the second lead screw 7 is fixedly connected to the output shaft of the second motor 8. This second thread transmission structure is the same as the first thread transmission structure mentioned above. That is, when the second motor 8 drives the second lead screw 7 to rotate clockwise or counterclockwise, the longitudinal slide plate 9 on it can move along the second lead screw 7, that is, the longitudinal slide plate 9 moves back and forth. This is the Y-axis thread transmission structure of the machine tool.

[0028] Since the moving direction and moving distance of the horizontal slide plate 5 and the vertical slide plate 9 are related to the rotation direction and number of rotations of the corresponding motors, in order to facilitate comprehensive servo control of the motors, motor 4 and motor 8 are servo motors. Thus, the moving direction and moving distance of the horizontal slide plate 5 and the vertical slide plate 9 can be effectively controlled through PLC servo control technology.

[0029] The servo control principle of the servo motor is a simple technical solution that is well-known and publicly disclosed by PLC technology professionals. This manual will not elaborate on its control principle in detail.

[0030] In this embodiment, in order to ensure the worm gear machining effect of the machine tool of this utility model, a machine base 10 is fixedly installed on the upper surface of the longitudinal slide plate 9, a spindle box 11 is fixedly installed on the machine base 10, and a drive motor 12 is fixedly installed on one side outer wall of the spindle box 11 by bolts. The output shaft of the drive motor 12 passes through the spindle box 11 and is fixedly connected to the cutter head 13. With this structural design, the drive motor 12 can drive the cutter head 13 to rotate rapidly, thereby providing the necessary conditions for the machining of the helical teeth of the worm gear through the rapid rotation of the cutter head 13.

[0031] Meanwhile, the machining position of the cutter head 13 can move left and right under the drive of the X-axis threaded transmission structure. In actual use, the X-axis threaded transmission structure can drive the cutter head 13 to move left and right, which can meet the left and right machining requirements of different worm lengths and improve the machining effect. The Y-axis threaded transmission structure can drive the cutter head 13 to move back and forth. In this way, the depth of cutter head 13 can be adjusted by moving the cutter head 13 back and forth, which has a certain dynamic adjustment effect of the depth of cut and can meet different worm machining requirements, thus having good structural practicality.

[0032] In this embodiment, in order to improve the movement guidance of the transverse slide 5 and the longitudinal slide 9 and to maintain the linearity and accuracy of the displacement, transverse guide rails 14 are fixedly installed on both sides of the first lead screw 3 and on the upper surface of the base 1, and longitudinal guide rails 15 are fixedly installed on both sides of the second lead screw 7 and on the upper surface of the transverse slide 5.

[0033] The transverse slide plate 5 is connected to the transverse guide rail 14 with a limiting sliding connection, and the longitudinal slide plate 9 is connected to the longitudinal guide rail 15 with a limiting sliding connection. Through the cooperation of the two sets of guide rails and the two sets of slide plates, the movement guidance of the transverse slide plate 5 and the longitudinal slide plate 9 can be effectively improved, so as to maintain the linearity and accuracy of the displacement.

[0034] In this embodiment, in order to fix and clamp the worm gear being processed, a fixing seat 16 is fixedly installed on both outer walls of the machine base 1 near the cutter head 13. A frame 17 is fixedly installed on both fixing seats 16. A threaded post 18 is internally threaded on the upper part of one frame 17, and a rotating shaft 20 is rotatably installed on the upper part of the other frame 17.

[0035] Furthermore, the threaded column 18 and the rotating shaft 20 are at the same horizontal height, and limit sleeves 22 are provided on the outer walls of the opposite side of the threaded column 18 and the rotating shaft 20.

[0036] The limiting sleeve 22 on the threaded column 18 is rotatably connected to the threaded column 18 via a bearing, and the limiting sleeve 22 on the rotating shaft 20 is fixedly connected to it; the two limiting sleeves 22 are coaxially arranged.

[0037] This structural design requires a worm gear that is machined to fit the dimensions of the limiting sleeve 22 of this utility model. Both ends of the worm gear can be tightly inserted into the limiting sleeves 22 on both sides. The limiting sleeves 22 at both ends can then clamp and hold the worm gear at its ends. For specific details, please refer to the appendix to the instruction manual. Figure 4 As shown.

[0038] In this embodiment, an adjusting turntable 19 is fixedly installed at the end of the threaded post 18 away from the limiting sleeve 22. With this structural design, the threaded post 18 can be manually driven to rotate by the adjusting turntable 19. When the threaded post 18 rotates, the limiting sleeve 22 at its top can move left and right. The distance between the two sleeves can be adjusted by the movement of a single limiting sleeve 22, which facilitates the precise insertion of the worm gear sleeve. It has a certain degree of adjustable distance and can be used for sleeve processing of worm gears of different lengths.

[0039] In this embodiment, in order to drive the worm to rotate, one end of the rotating shaft 20 is fixedly connected to the output shaft of the rotary motor 21. The rotary motor 21 is fixedly mounted on the frame 17. Thus, the rotary motor 21 can drive the worm to rotate through the rotating shaft 20, ensuring the machining effect of the helical teeth of the worm.

[0040] Working principle: When the worm gear processing machine tool of this utility model needs to process the worm gear, the worm gear that is adapted to the size of the limiting sleeve 22 of this utility model can be inserted between the two limiting sleeves 22. In this way, the two ends of the worm gear can be inserted and limited by the limiting sleeves 22 on both sides.

[0041] The present invention can drive the cutter head 13 to rotate rapidly by the drive motor 12, thereby providing the necessary rotation conditions for the machining of the helical teeth of the worm. At the same time, the rotary motor 21 can drive the worm to rotate through the rotating shaft 20 to ensure the machining effect of the helical teeth of the worm.

[0042] The rotating cutter head 13 can approach the worm under the drive of the Y-axis threaded transmission structure. When the rotating cutter head 13 contacts the rotating worm area, it can process and grind the helical teeth of the worm on the outer wall of the worm, thereby ensuring the normal processing and use of this utility model.

[0043] The cutting head 13 of this utility model can move left and right under the drive of the X-axis threaded transmission structure. In this way, the cutting head 13 can be driven to move left and right through the X-axis threaded transmission structure. In actual use, it can meet the left and right processing of different worm lengths and improve the processing effect. The cutting head 13 can be driven to move back and forth through the Y-axis threaded transmission structure. In this way, the depth of cut of the cutting head 13 can be adjusted by the back and forth movement of the cutting head 13. It has a certain dynamic adjustment effect of the depth of cut and can meet different worm processing requirements. It has good structural practicality.

[0044] Meanwhile, one of the limiting sleeves 22 of this utility model can move left and right under the rotation of the threaded column 18. Thus, the distance between the two sleeves can be changed by moving a single limiting sleeve 22. In actual use, it can meet the needs of worm gears of different lengths for sleeve processing, and has good structural applicability. At the same time, it is convenient for the rod to be inserted between the two limiting sleeves 22, which has a good adjustment effect and stronger adaptability. Moreover, the worm gear processing machine tool of this utility model has a simple overall structure, small footprint, and low manufacturing difficulty, which effectively reduces the initial purchase and subsequent use costs of enterprises, has good economic benefits, and is suitable for the development and use of small and micro manufacturing enterprises.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
