[0002] As a core component of mechanical transmission systems, gears achieve efficient transmission of power and motion through the meshing of teeth, and are widely used in automobiles, aerospace, robotics, smart homes, and other fields. Their manufacturing process encompasses multiple stages, including material selection, blank preparation, tooth profile machining, heat treatment, and precision machining. Gear grinding equipment is required when grinding the gear tooth grooves.
[0003] However, existing technologies have some problems: existing gear grinding devices usually grind the tooth grooves of the gear one by one with a grinding wheel. However, the tooth grooves of the gear are in multiple sets. Existing grinding devices have low grinding rates, which affects gear production efficiency. Therefore, we propose a gear grinding device.

[0022] 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.
[0023] like Figures 1 to 5 As shown in the figure, the gear grinding device provided in this embodiment of the utility model includes a base 1, which is rectangular and made of stainless steel. The main function of the base 1 is to support the entire device and ensure its normal operation.
[0024] Furthermore, a fixed seat 2 is rotatably connected to the base 1. A groove is provided inside the base 1, and the fixed seat 2 is rotatably connected inside the groove. A first motor 10 is fixedly connected inside the base 1, and the fixed seat 2 is fixedly connected to the output end of the first motor 10.
[0025] Specifically, by starting the first motor 10, the fixed seat 2 is driven to rotate in the rotating groove of the base 1, thereby causing the locking block 4 on the fixed seat 2 to rotate, which in turn causes the fixed gear on the locking block 4 to rotate, so that the grinding assembly 9 can mechanically grind the gear.
[0026] Furthermore, an adjusting block 3 is movably connected to the fixed base 2, a locking block 4 is fixedly connected to the adjusting block 3, and a driving component 5 is provided on the fixed base 2 to drive the adjusting block 3 to move.
[0027] Specifically, the drive assembly 5 includes a bevel gear disk 51, which is rotatably connected to the fixed base 2. A second motor 52 is fixedly connected to the fixed base 2, and a bevel gear 53 is fixedly connected to the output end of the second motor 52. The bevel gear 53 meshes with the bevel gear disk 51.
[0028] Furthermore, a sliding groove is provided on the fixed base 2, the adjusting block 3 is slidably connected in the sliding groove, a threaded block 54 is fixedly connected to the adjusting block 3, a threaded strip 55 is fixedly connected to the bevel gear disc 51, and the threaded strip 55 is threadedly connected to the threaded block 54.
[0029] Specifically, the second motor 52 starts and drives the bevel gear 53 to rotate. After the bevel gear 53 rotates, it drives the bevel gear disk 51 to rotate, which causes the threaded strip 55 on the bevel gear disk 51 to rotate, which in turn causes the threaded block 54 to move, thereby driving the adjusting block 3 and the locking block 4 to move, so that the device can fix gears of different specifications.
[0030] Furthermore, a support frame 6 is fixedly connected to the base 1, and a movable frame 7 is movably connected to the support frame 6. An adjustment groove is provided on the support frame 6, and the movable frame 7 is slidably connected in the adjustment groove. A hydraulic rod 11 is fixedly connected to the base 1, and the movable frame 7 is fixedly connected to the movable end of the hydraulic rod 11.
[0031] Specifically, the hydraulic rod 11 extends and retracts, causing the movable frame 7 to slide within the adjustment groove of the support frame 6, thereby adjusting the height of the movable frame 7 and thus changing the height of the grinding assembly 9, so that the height of the grinding assembly 9 is adapted to the height of the gear.
[0032] Furthermore, the movable frame 7 is provided with a slide rail, and a slider 8 is slidably connected in the slide rail. A bidirectional lead screw 12 is rotatably connected in the slide rail of the movable frame 7. The slider 8 is threadedly connected to the bidirectional lead screw 12. A third motor 13 is fixedly connected to the movable frame 7, and the bidirectional lead screw 12 is fixedly connected to the output end of the third motor 13.
[0033] Specifically, the third motor 13 starts and drives the bidirectional lead screw 12 to rotate. After the bidirectional lead screw 12 rotates, it drives the two sets of sliders 8 to slide in the slide rail of the moving frame 7, thereby changing the position of the sliders 8 and thus changing the position of the two sets of grinding components 9, so that the two sets of grinding components 9 can grind gears of different diameters.
[0034] Furthermore, a grinding assembly 9 is provided on the slider 8. The grinding assembly 9 includes a fourth motor 91, which is fixedly connected to the slider 8. A connector 92 is fixedly connected to the output end of the fourth motor 91, and a grinding wheel 93 is fixedly connected to the connector 92.
[0035] Specifically, the fourth motor 91 starts and drives the connector 92 to rotate. After the connector 92 rotates, it drives the grinding wheel 93 to rotate, so that the grinding wheel 93 grinds the surface of the gear.
[0036] The working process of this utility model is as follows: the gear is placed on the fixed seat 2, and then the second motor 52 is started to fix the gear in the center by the locking block 4. Then, the height of the moving frame 7 is adjusted by the hydraulic rod 11 so that the height of the grinding assembly 9 matches that of the gear. Then, the third motor 13 is started to adjust the grinding assembly 9 so that the grinding wheel 93 in the grinding assembly 9 contacts the gear. Then, the fourth motor 91 drives the grinding wheel 93 to rotate and grind the gear tooth groove. After the current tooth groove is ground, the first motor 10 is started to drive the fixed seat 2 to rotate so that the grinding wheel 93 grinds the next set of tooth grooves until all tooth grooves are ground.
[0037] The working principle of this utility model is as follows:
[0038] This utility model is equipped with two sets of grinding components 9, which can grind the tooth grooves on both sides of the gear at the same time, so that all the tooth grooves on the gear can be ground after the gear rotates half a turn, thereby speeding up the gear grinding rate.
[0039] This invention uses a hydraulic rod 11 to extend and retract, causing the movable frame 7 to slide within the adjustment groove of the support frame 6, thereby adjusting the height of the movable frame 7 and thus changing the height of the grinding assembly 9. This allows the grinding assembly 9 to grind gears of different thicknesses. Simultaneously, a third motor 13 can be started to drive the bidirectional lead screw 12 to rotate. After the bidirectional lead screw 12 rotates, it drives two sets of sliders 8 to slide within the slide rails of the movable frame 7, thereby changing the position of the sliders 8 and thus changing the position of the two sets of grinding assemblies 9. This allows the two sets of grinding assemblies 9 to grind gears of different diameters.
[0040] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
