TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible flywheels, in particular to an automatic assembly machine for flexible flywheels. BACKGROUND

[0002] A flexible flywheel is a mechanical device designed to absorb and store energy. Compared with traditional rigid flywheels, it has a special structural design that allows a certain degree of deformation or distortion during rotation, thereby better adapting to the dynamic changes of the power system.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0029] As shown in Figures 1 to 8 , an automatic assembly machine of a flexible flywheel comprises:

[0030] A moving mechanism 10, wherein the moving mechanism 10 comprises a workbench 101 and a rodless cylinder 102, the workbench 101 is divided into a taking and placing area and an assembly area, and the flexible flywheel 30 is transferred between the taking and placing area and the assembly area by the rodless cylinder 102;

[0031] The clamping mechanism 20 comprises inner supporting blocks 204, outer clamping blocks 205 and a hydraulic cylinder 215. The inner supporting blocks 204 are arranged in an inner ring, and the outer clamping blocks 205 are arranged in an outer ring. When the flexible flywheel 30 is clamped, the inner supporting blocks 204 of the inner ring are uniformly supported on the inner wall of the flexible flywheel 30 by the hydraulic cylinder 215, and the outer clamping blocks 205 of the outer ring are uniformly clamped on the outer wall of the flexible flywheel 30, so that the flexible flywheel 30 is uniformly stressed. When the flexible flywheel 30 is unloaded, the inner supporting blocks 204 of the inner ring are uniformly gathered on the inner side of the flexible flywheel 30 by the hydraulic cylinder 215, and the outer clamping blocks 205 of the outer ring are uniformly expanded on the periphery of the flexible flywheel 30, so as to expand the distance between the inner supporting blocks 204 of the inner ring and the outer clamping blocks 205 of the outer ring, thereby facilitating the loading and unloading of the flexible flywheel 30.

[0032] In the embodiment, the clamping mechanism 20 further comprises a mounting ring 201 and a mounting strip 214. The mounting ring 201 is provided with a plurality of mounting holes 201a arranged in a circle. Each mounting hole 201a is slidably connected with a mounting plate 202. The top end of the mounting plate 202 is symmetrically connected with a pair of guide strips 203 arranged in an "eight" shape.

The hydraulic cylinder 215 is vertically mounted at the center of the mounting strip 214, and the piston rod of the hydraulic cylinder 215 is connected with a lifting block 217. The lifting block 217 is uniformly connected with a plurality of lifting strips 218 around. The overhanging end of each lifting strip 218 is connected with the lower end of the corresponding mounting plate 202. The piston rod of the hydraulic cylinder 215 is extended to drive the lifting block 217 and all the lifting strips 218 to rise, thereby driving all the mounting plates 202 to synchronously rise. The inner supporting blocks 204 of the inner ring move radially inward, and the outer clamping blocks 205 of the outer ring move radially outward, so that the distance between the inner supporting blocks 204 and the outer clamping blocks 205 is expanded, thereby facilitating the loading and unloading of the flexible flywheel 30. The piston rod of the hydraulic cylinder 215 is retracted to drive the lifting block 217 and all the lifting strips 218 to descend, thereby driving all the mounting plates 202 to synchronously descend. The inner supporting blocks 204 of the inner ring move radially outward and are supported on the inner wall of the flywheel disc 301, and the outer clamping blocks 205 of the outer ring move radially outward and are clamped on the outer wall of the flywheel disc 301, so that the distance between the inner supporting blocks 204 and the outer clamping blocks 205 is expanded, thereby achieving uniform stress of the flywheel disc 301.

[0033] In the embodiment, the rodless cylinder 102 is arranged in a pair of parallel and horizontal distribution, the rodless cylinder 102 is horizontally installed on the workbench 101, and the moving plate 103 is connected on the pneumatic sliding of the rodless cylinder 102, and the mounting strip 214 is horizontally connected between the left and right two moving plates 103. The flexible flywheel 30 on the clamping mechanism 20 can be driven by the rodless cylinder 102 to transfer between the pickup area and the assembly area on the workbench 101.

[0034] In the embodiment, the inner side of the mounting ring 201 is coaxially connected with the circular pipe one 206, a plurality of guide rods one 207 are slidably connected on the circular pipe one 206, the outer end of each guide rod one 207 is connected to the corresponding inner support block 204, and the compression spring one 208 is sleeved on the guide rod one 207. The inner support block 204 can be assisted and guided by the guide rod one 207, and the inner support block 204 can be supported on the inner wall of the flexible flywheel 30 by the compression spring one 208.

[0035] In the embodiment, the outer side of the mounting ring 201 is coaxially connected with the circular pipe two 209, a plurality of guide rods two 210 are slidably connected on the circular pipe two 209, the inner end of each guide rod two 210 is connected to the corresponding outer clamping block 205, and the compression spring two 211 is sleeved on the guide rod two 210. The outer clamping block 205 can be assisted and guided by the guide rod two 210, and the outer clamping block 205 can be clamped on the outer wall of the flexible flywheel 30 by the compression spring two 211.

[0036] In the embodiment, the support strip 212 is connected between the adjacent two mounting plates 202, and the T-shaped support block 213 is connected at the center of the support strip 212. The edge of the flexible flywheel 30 can be supported by the support block 213, and the synchronous lifting of the flexible flywheel 30 and the mounting plate 202 can be ensured.

[0037] In the embodiment, a plurality of photoelectric sensors 219 are uniformly distributed on the periphery of the circular pipe two 209, and each photoelectric sensor 219 is connected to the outer wall of the circular pipe two 209 through the L-shaped sensor support 220. Whether there is a flexible disc 301 on the clamping mechanism 20 can be detected by the photoelectric sensor 219.

[0038] In the embodiment, the press-fitting mode of the ring gear 302 and the flywheel disc 301 can refer to the prior art CN118951673A.

[0039] The working principle of the automatic assembly machine for the flexible flywheel is as follows:

[0040] 1. The function of the moving mechanism 10 is realized:

[0041] The workbench 101 is provided with two functional areas of pickup area and assembly area.

[0042] The rodless cylinder 102 is horizontally installed on the workbench 101, and its slider drives the moving plate 103 to move linearly and reciprocally.

[0043] The mounting strip 214 is fixed between the left and right moving plates 103, thereby driving the entire clamping mechanism 20 to move smoothly between the pick-and-place area and the assembly area.

[0044] This structure realizes the automatic transfer of the flexible flywheel 30 between different stations, and improves the assembly continuity and efficiency.

[0045] 2. Action process of the clamping mechanism 20:

[0046] Clamping stage:

[0047] The hydraulic cylinder 215 is started to drive the lifting block 217 to move downward.

[0048] The lifting block 217 drives each mounting plate 202 to move downward synchronously through the multiple lifting strips 218.

[0049] The inner supporting block 204 expands outward under the action of the guide rod 207 and the compression spring 208, and adheres to the inner wall of the flexible flywheel 30.

[0050] At the same time, the outer clamping block 205 clamps the outer wall of the flexible flywheel 30 inward under the action of the guide rod 210 and the compression spring 211.

[0051] The inner supporting block 204 and the outer clamping block 205 cooperate to uniformly clamp the flexible flywheel 30, balance the stress, and avoid deformation.

[0052] Therefore, the above-mentioned disclosed embodiments are only examples in all aspects, and are not the only ones. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
