Description

Technical Field

[0001] This utility model relates to the field of automobile frame manufacturing technology, specifically an automobile frame straightening system. Background Technology

[0002] The chassis frame is the core load-bearing structure of a car, usually consisting of two longitudinal beams and several transverse beams. It is supported on the wheels by the suspension system. Its main function is to support the engine, transmission system, body and other components, bear the internal and external loads of the vehicle, and ensure driving stability and safety. It is commonly found in medium and large-sized cars.

[0003] During the production of automobile beams, due to their large size and heavy weight, movement relies entirely on hoisting. However, during hoisting, the contact area between the hoisting cable and the automobile beam is small, resulting in uneven stress on the surface of the beam. This leads to slight bending issues to some extent. Since the longitudinal beams are supported by transverse beams, the longitudinal beams usually do not deform along the direction of the transverse beams. Instead, they are more likely to bend vertically. The severity of bending is affected by factors such as the length, weight, and material hardness of the automobile beam. Therefore, in order to eliminate the bending problem caused by this process, we have designed and proposed an automobile beam straightening system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automobile beam straightening system to solve the problem of slight bending caused by hoisting during automobile beam production.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A vehicle frame straightening system includes a fixed frame. Conveying roller sets for conveying the vehicle frame body are installed near both ends inside the fixed frame. Several vibrating pressure rollers, positioning pressure rollers, vibrating idler rollers, and positioning idler rollers are respectively installed inside the middle of the fixed frame. The vibrating pressure rollers and positioning pressure rollers are in rolling connection with the upper surface of the vehicle frame body, and the vibrating idler rollers and positioning idler rollers are in rolling connection with the lower surface of the vehicle frame body. The vibrating pressure rollers and positioning pressure rollers, and the vibrating idler rollers and positioning idler rollers are spaced apart, and the vibrating pressure rollers and positioning idler rollers, and the positioning pressure rollers and vibrating idler rollers are arranged symmetrically vertically.

[0006] Preferably, the conveying roller assembly includes a conveying pressure roller that is rolledly connected to the upper surface of the main beam body and a conveying idler roller that is rolledly connected to the lower surface of the main beam body.

[0007] Preferably, there are no fewer than two sets of conveying rollers at each end of the fixed frame.

[0008] Preferably, there are at least two of each of the vibrating pressure roller, positioning pressure roller, vibrating idler roller, and positioning idler roller.

[0009] Preferably, the fixed frame is provided with a reinforced support frame at the position corresponding to the vibrating pressure roller and the vibrating idler roller, which is supported on the installation ground.

[0010] Preferably, both the vibrating pressure roller and the vibrating idler roller include a vibrating drum, end plates fixed at both ends inside the vibrating drum, and shafts and tubes fixed on the two end plates. The shafts and tubes are mounted on a fixed frame via vibrating bearings.

[0011] Preferably, a drive shaft is horizontally arranged inside the shaft tube and the vibrating drum, a drive motor connected to the drive shaft is installed on the fixed frame, a plurality of eccentric vibration blocks are fixed at equal intervals on the drive shaft, and vibration brackets supporting the inner wall of the vibrating drum are installed on the drive shaft located on both sides of the eccentric vibration blocks.

[0012] Preferably, the vibration support includes a vibration bearing seat mounted on the surface of the drive shaft, a support steel ring fixed to the inner wall of the vibration drum, and a support rib plate fixed between the vibration bearing seat and the support steel ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a set of conveyor rollers to horizontally transport the main beam body. Vibrating pressure rollers, positioning pressure rollers, vibrating idlers, and positioning idlers work together above and below the main beam body to straighten it. The positioning pressure rollers and positioning idlers vertically position the main beam body. The high-frequency vibration of the vibrating pressure rollers and vibrating idlers is equivalent to a hammer continuously striking the upper and lower surfaces of the main beam body, which not only eliminates internal stress but also corrects bending. This achieves the effect of straightening the main beam body and improving product quality, solving the problem of slight bending caused by hoisting during the production of automobile main beams.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-2 As shown, this utility model provides a technical solution: an automobile beam straightening system, including a fixed frame 1, with conveying roller groups 3 for conveying the beam body 2 installed inside the fixed frame 1 near both ends. There are no less than two conveying roller groups 3 at each end of the fixed frame 1. The conveying roller group 3 includes a conveying pressure roller that is rolledly connected to the upper surface of the beam body 2 and a conveying support roller that is rolledly connected to the lower surface of the beam body 2. Several vibrating pressure rollers 4, positioning pressure rollers 5, vibrating support rollers 6 and positioning support rollers 7 are respectively installed inside the middle position of the fixed frame 1. The vibrating pressure rollers 4 and positioning pressure rollers 5 are rolled to the upper surface of the main beam body 2, and the vibrating support rollers 6 and positioning support rollers 7 are rolled to the lower surface of the main beam body 2. There are no less than two of each of the following: vibrating pressure rollers 4, positioning pressure rollers 5, vibrating support rollers 6 and positioning support rollers 7. Vibrating roller 4 and positioning roller 5, and vibrating roller 6 and positioning roller 7 are spaced apart, and vibrating roller 4 and positioning roller 7, and positioning roller 5 and vibrating roller 6 are arranged symmetrically up and down. Reinforced support frame 8 is provided on the fixed frame 1 at the positions corresponding to vibrating roller 4 and vibrating roller 6, and is supported on the installation ground. Both the vibrating pressure roller 4 and the vibrating support roller 6 include a vibrating drum 9, end plates 10 fixed at both ends inside the vibrating drum 9, and shaft rods 11 and shaft tubes 12 fixed on the two end plates 10. The shaft rods 11 and shaft tubes 12 are mounted on the fixed frame 1 through vibrating bearings 13. A drive shaft 14 is horizontally arranged inside the shaft tube 12 and the vibrating drum 9. A drive motor 15 connected to the drive shaft 14 is installed on the fixed frame 1. Several eccentric vibration blocks 16 are fixed at equal intervals on the drive shaft 14. Vibration brackets 17 supporting the inner wall of the vibrating drum 9 are installed on the drive shaft 14 located on both sides of the eccentric vibration blocks 16.

[0018] Working principle: The transmission principle of the conveyor roller group 3 is the same as that of a regular roller conveyor. The vibrating pressure roller 4, positioning pressure roller 5, vibrating idler roller 6, and positioning idler roller 7 have no active rotation drive structure. They are driven to rotate freely by friction in contact with the main beam body 2. The conveyor roller group 3 conveys the main beam body 2 horizontally in the transverse direction. The vibrating pressure roller 4, positioning pressure roller 5, vibrating idler roller 6, and positioning idler roller 7 above and below the main beam body 2 cooperate to straighten the conveyed main beam body 2. The positioning pressure roller 5 and positioning idler roller 7 perform vertical positioning of the main beam body 2. The vibrating pressure roller 4 and vibrating idler roller 6 are driven by the drive motor 15 through the drive shaft 14 to drive the eccentric vibrating block 16 to rotate at high speed to generate eccentric vibration force, which is transmitted to the vibrating drum 9 through the vibrating bracket 17. The high-frequency vibration is transmitted to the main beam body 2 through the vibrating drum 9. The high-frequency vibration of the vibrating pressure roller 4 and vibrating idler roller 6 is equivalent to the hammer continuously hitting the upper and lower surfaces of the main beam body 2 to eliminate internal stress and correct bending.
