AI Technical Summary
The existing active gears are prone to fall off and fall during lifting, which poses safety hazards and is prone to collision with the machine tool fixture.
A spreader including a suspender, a support plate and a tension spring is designed. The support plate is hinged on the suspension rod, and the stabilization of the driving gear is achieved through the bayonet and the limiting rod. The tension spring is used to slow down the flip speed of the support plate, and the limit pin prevents the flip angle of the support plate from being too large.
Through this spreader, the driving gear can be safely flipped from a vertical posture to a horizontal posture, which facilitates loading and unloading, reduces labor intensity and safety hazards, and avoids gear drops and bumps with machine tool fixtures.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slings and relates to a sling used for slinging a driving gear. Background Art
[0002] During the gear processing, the pairing of large and small wheels is the last step of the processing. The pairing needs to be carried out on a special pairing machine. The structure and working principle of domestic pairing machines are basically the same. The existing pairing machine large wheel fixture uses a butterfly spring positioning plate to deform elastically under pressure and realize the gapless hole-shaft matching positioning with the large wheel through hole. The fixture flange surface is positioned with the back of the gear, and the large wheel is placed vertically with the tooth surface facing outward; the small wheel fixture uses an elastic thin-wall expansion sleeve to deform elastically under pressure and realize the gapless hole-shaft matching positioning with the small wheel journal. The fixture flange is positioned with the back of the small wheel crown, and the small wheel is placed horizontally. Before the fixture is clamped, the hole-shaft positioning clearance between the two sets of fixtures and the workpiece is only 0.1mm-0.2mm, and the pairing machine is manually operated to make the large and small wheel tooth surfaces mesh. During the loading and unloading of workpieces on the pairing machine, it is necessary to pay attention to the alignment of the gear and the fixture positioning element, and to avoid collision between the gear and the equipment and fixture. At present, a light lifting method with electromagnetic lifting equipment is often used to lift the driving gear. Since the gear part of the driving gear is a spiral bevel gear with an irregular surface, the electromagnetic lifting equipment is in point or line contact with the gear, which poses a great safety hazard. The driving gear is easy to fall off, and the gear is also prone to collision with the machine tool fixture. Utility Model Content
[0003] The problem solved by the utility model is to provide a driving gear hoisting device to solve the problem that the existing driving gear is easy to fall out of the hands during hoisting, which poses a potential safety hazard.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is: it includes a suspension rod, a support plate and a tension spring, the support plate is hinged at the middle and lower part of the suspension rod, a bayonet is opened at one end of the support plate, the input shaft of the driving gear passes through the bayonet, the gear part of the driving gear is supported by the support plate, and a limit rod is provided at the other end of the support plate, and the limit rod is used to limit the driving gear, one end of the tension spring is connected to the suspension rod, and the other end of the tension spring is connected to the limit rod, and a limit pin is provided at the lower part of the suspension rod, and the limit pin is used to limit the flipping angle of the support plate.
[0005] In the above technical solution, a more specific technical solution may also be: two tension springs are provided between the suspension rod and the limiting rod.
[0006] Furthermore: the suspension rod is provided with a bearing seat, the support plate is provided with a shaft rod, and the shaft rod is inserted into the bearing seat.
[0007] Further: a cylindrical bearing is provided between the shaft and the bearing seat.
[0008] Furthermore: a bayonet is provided at the end of the shaft rod, and the bayonet is used to prevent the cylindrical bearing from axial movement.
[0009] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the active gear can be flipped from a vertical posture to a horizontal posture through the suspension rod and the support plate, which is convenient for the active gear to be installed in the matching machine tool, reduces labor intensity, improves safety, can effectively prevent the active gear from falling, and can also reduce the collision between the active gear and the machine tool fixture.

[0017] The utility model is further described in detail below with reference to the accompanying drawings:
[0018] like Figures 1 to 6The active gear hanger shown includes a hanger rod 1, a support plate 2 and a tension spring 4. The support plate 2 is hinged at the middle and lower part of the hanger rod 1. A bayonet is provided at one end of the support plate 2. The input shaft of the active gear 6 passes through the bayonet. The gear part of the active gear 6 is supported by the support plate 2. A limit rod 3 is provided at the other end of the support plate 2. The limit rod 3 is used to limit the active gear 6. One end of the tension spring 4 is connected to the hanger rod 1. The other end of the tension spring 4 is connected to the limit rod 3. A limit pin 5 is provided at the lower part of the hanger rod 1. The limit pin 5 is used to limit the flip angle of the support plate 2 to ensure that the flip angle of the active gear 6 is 90°, so that the active gear 6 flips from a vertical posture to a horizontal posture. Two tension springs 4 are provided between the hanger rod 1 and the limit rod 3. When the active gear 6 flips with the support plate 2, the tension spring 4 slows down the flipping speed of the support plate 2. The limit rod 3 is used to limit the active gear 6 from coming out. When the active gear 6 is unloaded, the tension spring 4 pulls up the support plate 2 and rotates it back to its original position. The suspension rod 1 is provided with a bearing seat 11, and the support plate 2 is provided with a shaft rod 21, which is inserted into the bearing seat 11. A cylindrical bearing is provided between the shaft rod 21 and the bearing seat 11. A bayonet 22 is provided at the end of the shaft rod 21, and the bayonet 22 is used to prevent the cylindrical bearing from axial movement.
