[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 to Figure 7 As shown, this embodiment proposes a high-efficiency clamping device for gear processing, including a machine tool housing 1, a frame is arranged inside the machine tool housing 1, the frame includes a support plate 2, the support plate 2 is located inside the machine tool housing 1, a slide rail 3 is arranged on the top of the support plate 2, a fixed plate 25 is fixedly connected to the top of the slide rail 3, a mounting plate 4 is fixedly connected to one side of the support plate 2, a drive motor 5 is installed on the mounting plate 4, a rotating shaft 7 is rotatably installed inside the fixed plate 25, and a synchronous belt 6 is jointly sleeved on the outside of the output end of the rotating shaft 7 and the drive motor 5 through a synchronous wheel. Through the arrangement of structures such as a clamping plate 11 and a telescopic rod 16, when in use, the clamping plate 11 is driven by the bidirectional screw 9 to clamp the blank, and during the clamping process, a plurality of telescopic rods 16 that can be retracted individually are automatically adjusted to make it fit more closely with the surface of the blank, thereby achieving more stable clamping.

[0030] like Figure 1 to Figure 7 As shown, it also includes a fixing component 18, which includes a turntable 8, which is rotatably installed on one side of the fixing plate 25. A square groove is opened inside the turntable 8, and a bidirectional screw 9 is rotatably installed inside the square groove. One end of the bidirectional screw 9 extends out of the inside of the turntable 8.

[0031] like Figure 1 to Figure 7 As shown, a limit groove is provided on one side of the turntable 8, and two opposite threads are arranged on the outside of the bidirectional screw 9. The outsides of the two threads are assembled with transmission sleeves 10 through ball nuts, and one side of the two transmission sleeves 10 is fixedly connected with a clamping plate 11.

[0032] like Figure 1 to Figure 7 As shown, a plurality of circular holes are provided inside the clamping plate 11 , and interconnected oil filling holes 13 are provided between the plurality of circular holes. A pressurizer 12 is installed on one side of the clamping plate 11 , and the pressurizer 12 is connected to the oil filling hole 13 .

[0033] like Figure 1 to Figure 7 As shown, two symmetrically arranged fixing rings 14 are fixedly connected to the inside of the several circular holes, an elastic sleeve 15 is fixedly connected to one side of the two fixing rings 14, a telescopic rod 16 is slidably connected to the inside of the elastic sleeve 15, a telescopic spring 17 is welded to one end of the telescopic rod 16, and the other end of the telescopic spring 17 is welded to the inside of the circular hole.

[0034] In this embodiment, when in use, one end of the blank to be processed into a gear is placed between the two clamping plates 11. At this time, a wrench commonly used in a three-jaw chuck is inserted into the groove on the bidirectional screw 9, thereby driving the bidirectional screw 9 to rotate. When the bidirectional screw 9 rotates, the two transmission sleeves 10 can move toward each other along the direction of the thread, thereby driving the two clamping plates 11 to move. During the movement, the clamping plates 11 will continuously squeeze the blank to achieve fixation. During the fixing process, first, the telescopic rod 16 will contact the surface of the blank, thereby causing extrusion. During the extrusion, it is extended and retracted by the telescopic spring 17. Each telescopic rod 16 can be extended and retracted individually, so that a perfect fit with the blank can be achieved. On the surface, after each telescopic rod 16 is extended and retracted into place, the oil in the oil filling hole 13 arranged inside the splint 11 is pressurized by the pressurizer 12. It should be noted that the pressurizer 12 can be a common device on the market. As long as it can pressurize the oil, after pressurization, because the oil filling hole 13 is connected to the circular hole for installing the telescopic rod 16, the pressurized oil will exert pressure on the elastic sleeve 15. The elastic sleeve 15 is supported by elastic material. When the elastic sleeve 15 is under force, the telescopic rod 16 inside it will be fixed. At this time, the entire clamping process is completed. When it is necessary to start processing, start the drive motor 5, and drive the rotating shaft 7 through the synchronous belt 6, so as to realize the rotation of the entire turntable 8.

[0035] Example 2

[0036] like Figure 1 to Figure 7 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer sliding connection of the slide rail 3 is provided with a slider 19, the top of the slider 19 is fixedly connected with a mounting seat 23, and another fixed component 18 is rotatably provided on the mounting seat 23. Through the arrangement of structures such as the threaded rod 22 and the mounting seat 23, the threaded rod 22 is driven to rotate by the mobile motor 21. When the threaded rod 22 rotates, the mounting seat 23 can be moved. The entire stroke is increased by the influence of the threaded rod 22. At the same time, the stability is improved by the self-locking function of the threaded rod 22. After adjustment, the two ends of the blank can be fixed, thereby improving the overall flexibility of use.

[0037] like Figure 1 to Figure 7 As shown, one side of the support plate 2 is fixedly connected to a connecting plate 20, and a movable motor 21 is installed on one side of the connecting plate 20. The output end of the movable motor 21 is fixedly connected to a coaxially arranged threaded rod 22 through a coupling. The threaded rod 22 passes through the interior of the connecting plate 20, and one end of the threaded rod 22 is rotatably installed on the frame.

[0038] like Figure 1 to Figure 7 As shown, the outside of the threaded rod 22 is assembled with a moving plate 24 through a ball nut, and the top of the moving plate 24 is fixedly connected to the bottom of the mounting seat 23 .

[0039] In this embodiment, after one end of the blank has been fixed, the other end needs to be fixed depending on the length of the blank. If the blank is too long, it needs to be fixed. When it needs to be fixed, it is only necessary to start the moving motor 21 to drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, the moving plate 24 thereon will move along the direction of the thread, and at the same time, it will drive the entire mounting base 23 to move. A complete fixing component 18 is arranged above the mounting base 23, which is in a rotatable form, so as to fix the other end of the blank. After being fixed, it can rotate together with the rotation of the rotating shaft 7.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
