A flywheel gear ring press fitting device

Abstract

This utility model discloses a flywheel gear ring pressing device, relating to the field of flywheel processing technology. It includes a base, with a placement platform fixedly installed at the top center of the base for placing the flywheel. The design of this utility model utilizes a movable plate above the placement platform. A hydraulic cylinder drives the movable plate upward, causing the gear ring on the positioning ring to move to the inner side of the electromagnetic heating ring for heating. After the gear ring expands due to heating, the hydraulic cylinder drives the movable plate downward, while the mounting plates move closer together to position the gear ring, aligning its axis with the axis of the flywheel below. When the movable plate reaches the bottom of the support column, the gear ring is fitted onto the flywheel. After assembly, the mounting plates separate, allowing the positioning ring to move to both sides of the gear ring, facilitating the upward repositioning of the movable plate. Therefore, manual transfer of the gear ring is unnecessary, avoiding worker burns and improving processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of flywheel processing technology, and in particular to a flywheel gear ring press-fitting device. Background Technology

[0002] A flywheel ring gear is a structure fastened to the outer edge of a flywheel to mesh with the starter gear and drive the crankshaft to rotate. During production, the ring gear must first be heated to expand. After heating, workers transfer the ring gear to a pressing machine to mount it onto the outer edge of the flywheel. The excessively high temperature of the ring gear often results in burns to workers during the transfer, and the overall processing efficiency is low. Therefore, a flywheel ring gear pressing device is needed to solve these problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, this utility model provides a flywheel gear ring pressing device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a flywheel gear ring pressing device, including a base, a placement platform fixedly installed at the top center of the base for placing the flywheel, support columns fixedly installed near the four ends of the top of the base, a movable plate slidably installed on the support columns, two sets of mounting plates movably installed on the top of the movable plates, the two sets of mounting plates being symmetrically arranged, a positioning ring installed on the mounting plate for placing the gear ring, a top plate fixedly installed at the top of the support columns, an electromagnetic heating ring installed at the bottom center of the top plate, a hydraulic cylinder fixedly installed on the top of the top plate, and the power output shaft of the hydraulic cylinder fixedly connected to the movable plate.

[0005] Furthermore, guide seats are fixedly installed at both ends of each set of mounting plates, guide rods are slidably installed on the guide seats, support frames are fixedly installed at both ends of the guide rods, the support frames are fixedly installed on the movable plate, electric telescopic rods are fixedly installed at both ends of the movable plate, and connecting plates are fixedly installed at the power output ends of the electric telescopic rods. The connecting plates are fixedly installed on the side wall of the mounting plate away from the middle of the base.

[0006] Furthermore, an arc-shaped groove is provided on the adjacent sidewalls of the two sets of mounting plates, and the positioning ring is fixedly installed in the arc-shaped groove. A placement groove is provided on the inner sidewall of the positioning ring, and the diameter of the placement groove matches the size of the gear ring to be assembled. A limiting part is provided at the top of the placement groove.

[0007] Furthermore, a heater is fixedly installed on the top of the top plate, and the heater is electrically connected to the electromagnetic heating ring.

[0008] Furthermore, an air shaft is installed at the center of the placement platform, and a through groove is provided at the center of the moving plate.

[0009] The beneficial effects of this utility model are as follows: the design of this utility model features a movable plate above the placement platform. A hydraulic cylinder drives the movable plate upwards, causing the gear ring on the positioning ring to move to the inner side of the electromagnetic heating ring for heating. After the gear ring expands due to heating, the hydraulic cylinder drives the movable plate downwards. Simultaneously, the mounting plates move closer together to position the gear ring, aligning its axis with the axis of the flywheel below. When the movable plate descends to the bottom of the support column, the gear ring is fitted onto the flywheel. After assembly, the mounting plates separate, allowing the positioning ring to move to both sides of the gear ring, facilitating the upward movement and resetting of the movable plate. Therefore, manual transfer of the gear ring is unnecessary, preventing worker burns and improving processing efficiency. Attached Figure Description

[0018] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0019] according to Figure 1-6 As shown, a flywheel gear ring pressing device includes a base 1, a placement platform 2 fixedly installed at the top center of the base 1 for placing a flywheel 18, support columns 3 fixedly installed near the four ends of the top of the base 1, a movable plate 4 slidably installed on the support columns 3, two sets of mounting plates 5 movably installed on the top of the movable plate 4, the two sets of mounting plates 5 being symmetrically arranged, a positioning ring 6 installed on the mounting plate 5 for placing a gear ring 17, a top plate 7 fixedly installed at the top of the support columns 3, an electromagnetic heating ring 8 installed at the bottom center of the top plate 7, a hydraulic cylinder 9 fixedly installed on the top of the top plate 7, and the power output shaft of the hydraulic cylinder 9 being fixedly connected to the movable plate 4.

[0020] In this embodiment, guide seats 10 are fixedly installed at both ends of each set of mounting plates 5. Guide rods 11 are slidably installed on the guide seats 10. Support frames 12 are fixedly installed at both ends of the guide rods 11. The support frames 12 are fixedly installed on the movable plate 4. Electric telescopic rods 13 are fixedly installed at both ends of the movable plate 4 through brackets. Connecting plates 14 are fixedly installed at the power output end of the electric telescopic rods 13. The connecting plates 14 are fixedly installed on the side wall of the mounting plate 5 away from the middle of the base 1 by bolts. The mounting plate 5 is driven to move along the guide rods 11 by the electric telescopic rods 13. Under the drive of the electric telescopic rods 13, the two sets of mounting plates 5 move closer and further away from each other, so that the two sets of mounting plates 5 come together or separate.

[0021] In this embodiment, arc-shaped grooves 51 are provided on the adjacent sidewalls of the two sets of mounting plates 5. The positioning ring 6 is fixedly installed in the arc-shaped grooves 51. The inner sidewall of the positioning ring 6 is provided with a placement groove 61. The diameter of the placement groove 61 matches the size of the gear ring 17 to be assembled. The top of the placement groove 61 is provided with a limiting part 62. The gear ring 17 is supported by the placement groove 61. When the gear ring 17 is pressed onto the flywheel 18, when the two sets of mounting plates 5 come close to each other, the gear ring 17 is in close contact with the sidewall of the placement groove 61, thereby aligning the axis of the gear ring 17 with the center of the placement platform 2 below, and preventing the gear ring 17 from coming out of the placement groove 61 by the limiting part 62.

[0022] In this embodiment, a heater 15 is fixedly installed on the top of the top plate 7. The heater 15 is electrically connected to the electromagnetic heating ring 8 and supplies power to the electromagnetic heating ring 8 through the heater 15. The diameter of the electromagnetic heating ring 8 is larger than the diameter of the gear ring 17 to be assembled. When the gear ring 17 is heated, the electromagnetic heating ring 8 covers the outside of the gear ring 17. The principle of electromagnetic induction heating is existing technology and will not be described in detail here.

[0023] In this embodiment, an air shaft 16 is installed at the center of the placement platform 2, and a through groove 41 is opened at the center of the moving plate 4. When the flywheel 18 is placed on the placement platform 2, the center hole of the flywheel 18 is inserted into the air shaft 16, the flywheel 18 is fixed by the air shaft 16, and the placement platform 2 and the flywheel 18 are separated by the through groove 41.

[0024] In use, the flywheel 18 to be assembled is placed on the placement platform 2 and positioned by the air shaft 16. The gear ring 17 to be assembled is placed between two sets of positioning rings 6, with the two sets of positioning rings 6 slightly separated to leave placement space. Then, the hydraulic cylinder 9 drives the moving plate 4 to rise, causing the gear ring 17 to move to the inside of the electromagnetic heating ring 8 for heating. After the gear ring 17 heats and expands, the hydraulic cylinder 9 drives the moving plate 4 to descend. At the same time, the mounting plates 5, driven by the electric telescopic rod 13, move closer together to retract the gear ring 17. Positioning is performed so that the axis of the gear ring 17 is aligned with the axis of the flywheel 18 below. When the moving plate 4 descends to the bottom of the support column 3, the gear ring 17 is fitted onto the flywheel 18. After the gear ring 17 cools and shrinks, it is fixedly installed on the flywheel 18. After assembly, the electric telescopic rod 13 drives the mounting plate 5 to separate, so that the positioning ring 6 moves to both sides of the gear ring 17, so that the moving plate 4 can move upward and reset. Therefore, there is no need to manually transfer the gear ring 17, thereby avoiding the situation of workers being burned and improving processing efficiency.
