Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, specifically an automated production line for forging LHR bearing rings. Background Technology

[0002] As a core component in the field of precision mechanical transmission, LHR bearing rings are made of high-carbon chromium bearing steel, carburized steel and other high-quality materials, and are manufactured through precision machining processes such as forging, turning, heat treatment and grinding. They have the characteristics of high hardness, high wear resistance and high dimensional stability, and are widely used in industrial fields such as automobiles, machine tools, wind power and rail transportation. The inner and outer ring raceways are ultra-precision machined to reduce the coefficient of friction, and together with the cage and rolling elements, they achieve smooth operation. Modern technology further improves fatigue life through surface strengthening, ion implantation and other processes, while computer simulation is used to optimize the stress distribution to meet the demanding working conditions such as high speed, heavy load and long life.

[0003] However, it still has some drawbacks. For example, the LHR bearing ring forging production line has problems such as low clamping efficiency and complicated operation. Traditional clamping devices require manual adjustment of positioning, which is time-consuming and labor-intensive, and the clamping stability is insufficient. During high-speed punching, the workpiece is prone to shift, affecting the processing accuracy. At the same time, the complicated fixing steps increase the labor intensity of operators and restrict the automation level and overall efficiency of the production line.

[0004] To address the aforementioned issues, this application proposes an automated production line for forging LHR bearing rings. Utility Model Content

[0005] The purpose of this invention is to provide an automated production line for forging LHR bearing rings, so as to solve the problems of low efficiency and poor stability of traditional clamping devices mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automated production line for forging LHR bearing rings, comprising a main body of the production line, a bearing ring quick clamping device fixedly connected above the main body of the production line, a conveyor belt device movable inside the main body of the production line, the conveyor belt device movable below the bearing ring quick clamping device, a tightening linkage device installed on one side of the bearing ring quick clamping device, and a linkage frame fixedly connected above the front of the bearing ring quick clamping device. This bearing ring quick clamping device facilitates simpler and faster fixing of bearing rings requiring punching, assists in punching processing, improves clamping stability during processing, and simplifies operation, avoiding complicated fixing operations, and has good application prospects.

[0007] Preferably, a rotation limiting frame is fixedly connected above the rear end of the bearing ring quick clamping device, and the rotation limiting frame has two sets that are mirror-corresponding to each other. The linkage frame and the rotation limiting frame form a groove for clamping the bearing ring above the bearing ring quick clamping device.

[0008] Preferably, a punching machine bracket is fixedly connected to the rear end of the main body of the production line, a movable rod is fixedly connected to one side of the punching machine bracket, the main body of the punching machine is movably mounted on the surface of the movable rod, and a punching machine drill bit is installed below the main body of the punching machine.

[0009] Preferably, a crank device is fixedly connected to one side of the tightening linkage device, and an active bidirectional threaded rod is fixedly connected to the other side of the tightening linkage device. A limit post is fixedly connected to the middle surface of the active bidirectional threaded rod, and threaded layers are provided on both ends of the active bidirectional threaded rod and are mirror-corresponding. One side of the active bidirectional threaded rod is movable inside the linkage frame, and the other side of the active bidirectional threaded rod is movable inside the rotation limit frame. A limit rotating disk is fixedly connected to the other side of the active bidirectional threaded rod.

[0010] Preferably, the limiting rotating disk is movable inside the rotation limiting frame, a linkage chain is movable on one side of the active bidirectional threaded rod, the other side of the linkage chain is movable on one side of the driven bidirectional threaded rod, a limiting post is fixedly connected to the middle surface of the driven bidirectional threaded rod, threaded layers are provided on both ends of the driven bidirectional threaded rod and are mirror-corresponding, one side of the driven bidirectional threaded rod is movable inside the linkage frame, and the other side of the driven bidirectional threaded rod is movable inside the rotation limiting frame.

[0011] Preferably, a limiting rotating disk is fixedly connected to one side of the driven bidirectional threaded rod, and a friction damping ring is fixedly connected to the front of the bearing ring quick clamping device. A tightening linkage device is movably connected to one side of the friction damping ring. The threaded layers on the surfaces of the driving and driven bidirectional threaded rods slide within the threaded grooves. The threaded grooves are formed on both sides of the clamping plate. The clamping plate has two sets of mirror-corresponding clamping plates. The clamping plate moves above the bearing ring quick clamping device. In use, the bearing ring quick clamping device forms a groove for clamping the workpiece through the linkage frame and the rotating limiting frame. When the bearing ring is conveyed... When the conveyor belt is transported to the processing position, the operating crank drives the active bidirectional threaded rod to rotate, which in turn drives the driven bidirectional threaded rod to rotate synchronously via a linkage chain. The mirrored thread layers of the active and driven bidirectional threaded rods push the clamping plates on both sides to move towards each other along the threaded grooves. Friction damping rings enhance the stability of rotation, ensuring that the two sets of clamping plates precisely clamp the bearing rings. Limiting posts and limiting rotating discs ensure stable operation of the threaded rods within the frame, preventing skewing or disengagement. This design achieves single-action bidirectional clamping through mechanical linkage, simplifying the operation process while ensuring the workpiece's resistance to displacement during punching.

The limiting post 54 is fixedly installed on the middle surface of the driven bidirectional threaded rod 53. Mirror-symmetrical threaded layers are machined on both ends of the driven bidirectional threaded rod 53. The linkage frame 41 accommodates the movement of one side of the driven bidirectional threaded rod 53, and the rotating limiting frame 42 accommodates the movement of the other side of the driven bidirectional threaded rod 53. The limiting rotating disk 55 is fixed to one side of the driven bidirectional threaded rod 53. The friction damping ring 7 is fixedly installed on the front of the bearing ring quick clamping device 4 and forms a movable contact with the tightening linkage device 5. The thread layers of the driving bidirectional threaded rod 52 and the driven bidirectional threaded rod 53 form a sliding fit with the threaded grooves 61 opened on both sides of the clamping plate 6. The two sets of mirror-symmetrical clamping plates 6 form a movable connection above the bearing ring quick clamping device 4. In use, the bearing ring quick clamping device 4 forms a groove for clamping the workpiece through the linkage frame 41 and the rotation limiting frame 42. When the bearing ring is transported to the processing position by the conveyor belt device 11, the crank device 51 is operated. The active bidirectional threaded rod 52 is driven to rotate, and the driven bidirectional threaded rod 53 is driven to rotate synchronously through the linkage chain 56. The mirror thread layers of the active bidirectional threaded rod 52 and the driven bidirectional threaded rod 53 push the clamping plates 6 on both sides to move towards each other along the thread groove 61. The friction damping ring 7 is used to enhance the stability of rotation, so that the two sets of clamping plates 6 can accurately clamp the bearing ring.

The bearing ring quick clamping device 4 facilitates simpler and faster fixing of bearing rings that need to be punched, assists in punching processing, improves clamping stability during processing, and simplifies operation, avoiding complicated fixing operations, and has good application prospects.

[0022] In this embodiment, as shown Figures 1-2 As shown, two sets of mirror-symmetrical rotation limiting frames 42 are fixedly connected above the rear end of the bearing ring quick clamping device 4.

It has promising application prospects. In use, the quick-clamping device 4 forms a clamping groove for the workpiece through a linkage frame 41 and a rotation limiting frame 42. When the bearing ring is conveyed to the processing position by the conveyor belt device 11, the operating crank device 51 drives the active bidirectional thread. The rotation of rod 52 synchronously drives the driven bidirectional threaded rod 53 to rotate via the linkage chain 56. The mirrored thread layers of the driving bidirectional threaded rod 52 and the driven bidirectional threaded rod 53 push the clamping plates 6 on both sides to move towards each other along the thread groove 61. The friction damping ring 7 enhances the stability of rotation, so that the two sets of clamping plates 6 can accurately clamp the bearing rings.
