[0033] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0034] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the technical solution of this utility model is as follows: a grinding device for processing spline shafts, comprising: a groove 2 on the front side of the upper end face of a support platform 1, the groove facilitating the sliding of a bushing 501; an annular groove 3 on the upper end face of the support platform 1; a hole 4 on the rear end face of the support platform 1; a reciprocating moving component 6 connected to the hole 4; and a fixing component 5 connected to the annular groove 3. The fixing component 5 includes: a bushing 501, which is slidably connected to the annular groove 3; a through groove 502 on the upper end face of the bushing 501; a support plate 503 fixedly connected to the upper end face of the bushing 501, the support plate 503 being located behind the through groove 502; a bolt 504 threadedly connected to the upper end face of the support plate 503; a locking block 505 rotatably connected to the lower end of the bolt 504, the locking block 505 being embedded in the through groove 502; and a rear fixing plate 506 fixedly connected to the rear end face of the bushing 501. The bolt 504 rotates to drive the locking block 505 to press and fix the spline shaft 8.

[0036] like Figure 3 and Figure 5As shown, the reciprocating moving assembly 6 includes: a rear fixing plate 506 fixedly connected to the upper front end of the linkage column 601; a half-shaft rod 602 fixedly connected to the front side of the lower end face of the linkage column 601, with several teeth fixedly connected to the lower end face of the half-shaft rod 602; a limiting block 603 fixedly connected to the front two end faces of the half-shaft rod 602; a gear 604 connected to the lower end face of the half-shaft rod 602, with the gear 604 meshing with the half-shaft rod 602; a protective shell 605 fixedly connected to the rear end face of the support platform 1, with the gear 604 and the half-shaft rod 602 located in the protective shell 605; the rotation of the gear 604 drives the bushing 501 to move, and the limiting block 603 limits the movement of the bushing 501. A motor 606 is fixedly connected to one side of the protective shell 605, with the drive end of the motor 606 fixedly connected to the gear 604, providing power for the rotation of the gear 604.

[0037] like Figures 1 to 3 As shown, grooves 401 are opened on both sides of the hole 4, and the limiting block 603 is slidably connected in the groove 401. A grinding ring 7 is fixedly connected to the upper end face of the groove 2. A spline shaft 8 is connected in the bushing 501. The spline shaft 8 is slidably connected in the grinding ring 7. The grinding ring 7 grinds the burrs in the groove of the spline shaft 8.

[0038] In practical use, place the device in a suitable position, then insert the splined shaft 8 into the bushing 501. Then, rotate the bolt 504 to drive the locking block 505 to fix the splined shaft 8 in place. Then, start the motor 606 to drive the gear 604 to rotate. When the gear 604 rotates, it meshes with the half shaft 602 through the tooth block, causing the bushing 501 and the splined shaft 8 to move backward. When the splined shaft 8 moves backward, the grinding ring 7 rubs and grinds the groove in the splined shaft 8. When the limiting block 603 slides to the rear end of the slide groove 401, the motor 606 reverses and pushes the splined shaft 8 forward, so that it rubs and grinds against the grinding ring 7 repeatedly. After one end is ground, remove the splined shaft 8 and insert the ground end into the bushing 501. Repeat the above operation to grind in a cycle.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
