[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-7 This utility model provides a technical solution: a gear end face grinding device, including a base 1; Grinding component 8 for grinding the end face of gears; And the gear fixing fixture 5 for fixing the gear; The gear fixing fixture 5 includes a connecting shaft 501. A tapered cylinder 502 is fixedly installed on one end of the connecting shaft 501 facing the grinding component 8. A threaded rod 503 is fixedly installed on the other end of the tapered cylinder 502 facing the grinding component 8. An adjustable spline 504 is provided on the tapered cylinder 502. A gear clamping assembly 505 is sleeved on the threaded rod 503. The tapered cylinder 502 is used to pass through the center of the gear. The adjustable spline 504 is used to engage with the keyway inside the gear. The gear clamping assembly 505 is used to clamp the gear onto the tapered cylinder 502. The tapered cylinder 502 with varying diameter is used as the central shaft to support the gear and can adapt to gears with different inner diameters. The adjustable spline 504 cooperates with the gear keyway so that the gear will not rotate relative to the tapered cylinder 502 during the grinding process. The gear clamping assembly 505 tightly clamps the gear to prevent axial displacement of the gear during the grinding process. The adjustable spline 504 includes a through groove 5041 and a fixing plate 5043. The through groove 5041 is formed on the outer wall of the tapered cylinder 502. The fixing plate 5043 is fixedly installed on the outer wall of the tapered cylinder 502. A spline plate 5042 is movably arranged in the through groove 5041. Two spline plates 5042 are provided. The inner wall of the fixing plate 5043 is rotatably connected to a double-acting screw 5044 through a bearing. The two spline plates 5042 are threaded onto the double-acting screw 5044 and are connected to different threads on the double-acting screw 5044. The two spline plates 5042 form a spline for engaging into a gear keyway. The rotation of the double-acting screw 5044 causes the two spline plates 5042 to move, changing the distance between the two spline plates 5042, thereby changing the size of the spline, and then matching it with different gear keyways. The gear clamping assembly 505 includes a tapered sleeve 5051 and a fixing nut 5052. The tapered sleeve 5051 is movably sleeved on the tapered cylinder 502 and the threaded rod 503, and the inner diameter of the tapered sleeve 5051 is larger than the outer diameter of the tapered cylinder 502. The fixing nut 5052 is threaded onto the threaded rod 503 and abuts against the tapered sleeve 5051. The tapered sleeve 5051 is used to abut against the gear to prevent the gear from shifting axially during the grinding process. The fixing nut 5052 abuts against the tapered sleeve 5051 to ensure that the tapered sleeve 5051 always abuts against the gear during the grinding process. A motor 2 is fixedly installed on the top of the base 1. A rotating shaft 3 is fixedly installed on the output end of the motor 2. The rotating shaft 3 is detached from the gear fixing fixture 5 through a flange connector 4. By using the flange connector 4 to connect the rotating shaft 3 and the gear fixing fixture 5, the gear fixing fixture 5 can be disassembled. The motor 2 drives the rotating shaft 3 to rotate, which in turn drives the gear fixing fixture 5 to rotate. The rotation of the gear fixing fixture 5 drives the gear to rotate, which is used to switch the end face that is being ground on the gear. The grinding component 8 includes an X-axis electric slide rail 801, which is fixedly mounted on the top of the base 1. A Y-axis electric slide rail 802 is fixedly connected to the movable end of the X-axis electric slide rail 801. A T-shaped mounting base 803 is fixedly mounted on the movable end of the Y-axis electric slide rail 802. A second motor 804 is fixedly mounted on the T-shaped mounting base 803. A second rotating shaft 805 is fixedly mounted on the output end of the second motor 804. A connecting seat 806 is fixedly mounted on the second rotating shaft 805, and the connecting seat 806 is installed and removed using screws. A grinding head 807 is provided, and a movable adjustment platform is formed by the Y-axis electric slide rail 802 and the X-axis electric slide rail 801. This platform is used to adjust the position of the T-type mounting base 803, and in turn, adjust the positions of the second motor 804, the second rotating shaft 805, the connecting seat 806, and the grinding head 807, so that the grinding head 807 can contact the end face of the gear. The second motor 804 drives the second rotating shaft 805 to rotate, which in turn drives the connecting seat 806 to rotate. The rotation of the connecting seat 806 drives the grinding head 807 to rotate and grind the end face of the gear. Both ends of the double-acting lead screw 5044 are fixedly installed with adjusting nuts 7. The end face of the adjusting nut 7 is provided with a hexagonal groove 701. The adjusting nut 7 and the hexagonal groove 701 are provided so that when rotating the double-acting lead screw 5044, a tool (wrench, Allen wrench, etc.) can be used to rotate the adjusting nut 7, and then drive the double-acting lead screw 5044 to rotate. Compared with directly rotating the double-acting lead screw 5044 by hand, this method is more labor-saving and easier to operate. A silicone pad 6 is fixedly provided on the side of the tapered sleeve 5051 that contacts the gear. When the sliding tapered sleeve 5051 abuts against the gear, the silicone pad 6 can act as a buffer to prevent the tapered sleeve 5051 from directly hitting the gear. Shock-absorbing seats 10 are fixedly installed at the four corners of the bottom of the base 1. The base 1 is covered by an equipment shell 9. A protective frame 11 is fixedly installed on the top of the base 1, and the protective frame 11 surrounds the grinding component 8.

[0017] Working principle: In use, pass the gear through the threaded rod 503, then pull the gear along the conical cylinder 502 until the gear is locked in place. At this time, hold the gear with one hand and use a tool to turn the adjusting nut 7 with the other hand, which in turn rotates the double-acting screw 5044, causing the two splined plates 5042 to move until the splined plates 5042 abut against the gear keyway. Then pull the conical sleeve 5051 to abut against the gear, and tighten the fixing nut 5052 to secure the conical sleeve 5051. The X-axis electric slide rail 801 is used for this operation. The movable adjustment platform, composed of the Y-axis electric slide rail 802, adjusts the position of the grinding head 807 so that the grinding head 807 can contact the end face of the gear. The second motor 804 is turned on to drive the second rotating shaft 805 to rotate, which in turn drives the connecting seat 806 to rotate. The rotation of the connecting seat 806 drives the grinding head 807 to rotate and grind the end face of the gear. After the end face of one tooth is ground, the first motor 2 is turned on to drive the first rotating shaft 3 to rotate, which in turn drives the gear fixing fixture 5 to rotate. The rotation of the gear fixing fixture 5 drives the gear to rotate, which is used to switch the end face of the gear being ground.
