Technical Field

[0001] The utility model relates to the technical field of detection jigs, in particular to a gear assembly precision detection device. Background Art

[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Gears are key components of mechanical manufacturing or transmission. When used, gears need to be used in conjunction with gear assemblies, such as gear shafts and other types of gears that need to mesh. In order to ensure the matching requirements between gears, staff are required to perform precision inspections on gear assemblies.

[0003] During the inspection process, the gear assembly needs to be fixed so that the operator can inspect the gear assembly with the help of the inspection instrument. However, the existing inspection device cannot quickly fix and remove gear assemblies of various shapes and sizes, resulting in a lot of time wasted in the fixing work, which in turn affects the inspection efficiency of the accuracy of the gear assembly.

[0004] Therefore, we designed a gear assembly accuracy detection device. Utility Model Content

[0023] Reference Figure 1-Figure 4A gear assembly precision detection device includes a placement table 1, an electric hydraulic cylinder 2 is fixedly connected to the top plate of the placement table 1, a U-shaped plate 3 is fixedly connected to the output end of the electric hydraulic cylinder 2, a bearing 10 is fixedly connected to the bottom plate of the placement table 1, and the bearing 10 is arranged to facilitate the rotation of a cylinder 5 on the placement table 1, the bearing 10 and the U-shaped plate 3 are both connected to the cylinder 5, and a fixing mechanism for fixing the gear assembly is provided in the cylinder 5, and the fixing mechanism includes a plurality of L-shaped plates 6 for clamping the gear assembly.

[0024] Reference Figure 1 As shown, the cylinder 5 is rotatably connected to the U-shaped plate 3, the U-shaped plate 3 is fixedly connected with a motor 4, and the output end of the motor 4 is coaxially fixed with the cylinder 5. When in use, the gear assembly is first clamped and fixed by a fixing mechanism, and then the motor 4 is started to drive the cylinder 5 and the gear assembly fixed on the cylinder 5 to rotate, so that the operator can detect the gear assembly through the detection instrument.

[0025] Reference Figure 2 and Figure 3 As shown, the fixing mechanism also includes a round rod 9, which slides through the cylinder 5; the other end of the round rod 9 is fixedly connected to a fixing platform 8; the fixing mechanism also includes a plurality of pillow blocks 15, which are fixedly connected to the round rod 9, and the L-shaped plate 6 is rotatably connected to the pillow blocks 15 through a rotating shaft;

[0026] The fixing mechanism also includes a plurality of rubber balls 7, which are fixedly connected to the ends of the L-shaped plate 6. The gear assembly is clamped by the rubber balls 7 to prevent the ends of the L-shaped plate 6 from damaging the surface of the gear assembly and affecting the accuracy. The rubber balls 7 can also increase the friction between the L-shaped plate 6 and the gear assembly, making it easier to drive the gear assembly to rotate. A circular plate 11 is fixedly connected to one end of the round rod 9, and the circular plate 11 slides in the cylinder 5. A spring 12 is fixedly connected between the circular plate 11 and the cylinder 5.

[0027] When in use, the gear assembly is placed on the lower fixed platform 8, and the electric hydraulic cylinder 2 is started to drive the upper fixed platform 8 to press down, so that the gear assembly is fixed between the two fixed platforms 8; during the pressing process, the fixed platform 8 drives the round rod 9 to move into the cylinder 5, and the round rod 9 compresses the spring 12 through the round plate 11. At the same time, the round rod 9 drives the multiple L-shaped plates 6 to rotate in the direction of the fixed platform 8 through the pillow block 15, so that the multiple rubber balls 7 move toward the fixed platform 8, thereby clamping the gear assembly on the fixed platform 8, and the fixing method is simple and fast;

[0028] When removing the gear assembly fixed on the fixed platform 8, it is only necessary to drive the electric hydraulic cylinder 2 to drive the upper fixed platform 8 to move upward. At this time, the fixed platform 8 is no longer squeezed, and the compressed spring 12 is reset to push the circular plate 11 and the round rod 9 to move outside the cylinder 5. The round rod 9 drives the multiple L-shaped plates 6 to rotate away from the fixed platform 8 through the pillow block 15, so that the multiple rubber balls 7 are away from the fixed platform 8, thereby releasing the clamping of the gear assembly on the fixed platform 8. The operation is convenient and the time consumption of the fixing work is greatly reduced.

[0029] Reference Figure 3 and Figure 4 As shown, a plurality of L-shaped plates 6 are provided with slide grooves 13, a plurality of cylindrical blocks 14 are provided on the side wall of the cylinder 5, and the cylindrical blocks 14 are slidably connected to the slide grooves 13. When the L-shaped plates 6 rotate on the pillow blocks 15, the L-shaped plates 6 will slide on the cylindrical blocks 14 through the slide grooves 13.

[0030] The working principle of the utility model is as follows:

[0031] Place the gear assembly on the lower fixed platform 8, start the electric hydraulic cylinder 2 to drive the upper fixed platform 8 to press down, and fix the gear assembly between the two fixed platforms 8;

[0032] At the same time, during the pressing process, the fixed platform 8 drives the round rod 9 to shrink into the cylinder 5, and the round rod 9 compresses the spring 12 through the circular plate 11. At the same time, the shrinking round rod 9 drives the multiple L-shaped plates 6 to rotate toward the fixed platform 8 through the pillow block 15, so that the multiple rubber balls 7 move toward the fixed platform 8, thereby clamping the gear assembly on the fixed platform 8. The fixing method is simple and fast.

[0033] When removing the gear assembly fixed on the fixed platform 8, it is only necessary to drive the electric hydraulic cylinder 2 to drive the upper fixed platform 8 to move upward. At this time, the fixed platform 8 is no longer squeezed, and the compressed spring 12 is reset to push the circular plate 11 and the round rod 9 to move outside the cylinder 5. The round rod 9 drives the multiple L-shaped plates 6 to rotate away from the fixed platform 8 through the pillow block 15, so that the multiple rubber balls 7 are away from the fixed platform 8, thereby releasing the clamping of the gear assembly on the fixed platform 8. The operation is convenient and the time consumption of the fixing work is greatly reduced.
