Description

Technical Field

[0001] This utility model relates to the field of correction component technology, specifically a chassis longitudinal beam correction component. Background Technology

[0002] The chassis is a frame structure that spans the front and rear axles of a car, commonly known as the main beam. It is the base of the car and is generally composed of two longitudinal beams and several transverse beams. It is supported on the wheels via the suspension system, front axle, and rear axle. The chassis must have sufficient strength and rigidity to withstand the load of the car and the impact transmitted from the wheels. The function of the chassis is to support and connect the various assemblies of the car, keep the assemblies in a relatively correct position, and withstand various loads inside and outside the car.

[0003] The longitudinal beam of the vehicle frame is a bridging component between the front and rear suspensions. Both ends of the longitudinal beam need to be bent to match the front and rear suspensions. A patent search reveals a device, such as publication number "CN217289875U," entitled "A Vehicle Frame Longitudinal Beam Correction Device." However, this device cannot correct the angles at both ends of the longitudinal beam, thus reducing its correction effectiveness. Therefore, this invention designs a vehicle frame longitudinal beam correction assembly to solve the aforementioned problem. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A preferred embodiment of the chassis longitudinal beam straightening assembly provided by this utility model is, for example... Figures 1 to 4As shown: A frame longitudinal beam straightening assembly includes an operating platform 1, a limiting plate 2 fixedly mounted on the top rear end of the operating platform 1; a baffle 3 mounted on the top front end of the operating platform 1; a rotating rod 4 rotatably mounted on the left and right sides of the front end inside the operating platform 1, a gear 5 fixedly sleeved on the lower end of the rotating rod 4, a connecting plate 6 fixedly sleeved on the upper end of the rotating rod 4, and a top column 7 rotatably connected to the end of the connecting plate 6 away from the rotating rod 4; a drive assembly 8 assembled outside the operating platform 1, which can rotate in conjunction with the rotating rod 4, the drive assembly 8 including a first electric push rod 801 fixedly mounted on the rear end of the operating platform 1; a placement plate 802 fixedly mounted outside the first electric push rod 801, and racks 803 fixedly mounted on the left and right sides of the front end of the placement plate 802.

[0028] The rack 803 and the gear 5 are designed to correspond to each other one by one. The rack 803 and the gear 5 mesh with each other. The rack 803 and the placement plate 802 are slidably connected to the operating table 1. The output end of the first electric push rod 801 slides through the operating table 1 and is fixedly connected to the placement plate 802.

[0029] It should be noted that the existing frame longitudinal beam straightening components still have certain shortcomings in actual use. They cannot correct the angles at both ends of the longitudinal beam, thus reducing the straightening effect of the longitudinal beam.

[0030] In this embodiment, the operator first places the longitudinal beam between the limiting plate 2 and the baffle 3, thereby positioning the longitudinal beam by the limiting plate 2 and the baffle 3. At the same time, the left and right ends of the longitudinal beam are on the left and right sides outside the limiting plate 2 and the baffle 3. The operator then activates the first electric push rod 801. The first electric push rod 801 controls the placement plate 802 to drive the rack 803 to move forward along the direction of the operating table 1. At this time, the rack 803 controls the gear 5 to drive the rotating rod 4 together with the connecting plate 6 and the top column 7 to rotate along the direction of the longitudinal beam. The rotating top column 7 simultaneously exerts a thrust on the left and right ends of the longitudinal beam, thereby correcting the angle of the left and right ends of the longitudinal beam.

[0031] In a further preferred embodiment of this utility model, a guide hole 9 is integrally provided in the middle of the inside of the operating table 1. The guide hole 9 is a through hole design. A slider 10 is slidably connected inside the guide hole 9. The front cross-section of the slider 10 is the same as the front cross-section of the guide hole 9. The top of the slider 10 is fixedly connected to the bottom of the baffle 3. A displacement component is provided inside the guide hole 9. The displacement component can control the baffle 3 to move along the direction of the guide hole 9. The displacement component includes a second electric push rod 11 disposed inside the guide hole 9. The second electric push rod 11 is fixedly connected to the operating table 1. A top rod 12 is fixedly disposed at the rear end of the second electric push rod 11 and is fixedly connected to the slider 10. A controller 13 is fixedly disposed on the outer wall of the operating table 1. The controller 13 is connected to the first electric push rod 801 and the second electric push rod 11 through wires. A pressure sensor 14 is fixedly disposed at the rear end of the baffle 3. The pressure sensor 14 is a thin-film pressure sensor and is connected to the controller 13 through wires.

[0032] In this embodiment, after the longitudinal beam is placed between the limiting plate 2 and the baffle 3, the operator first activates the second electric push rod 11. The second electric push rod 11 controls the top rod 12 to drive the slider 10 and the baffle 3 to move along the direction of the guide hole 9, that is, the baffle 3 moves along the direction of the limiting plate 2, thereby causing the baffle 3 and the limiting plate 2 to clamp and fix the longitudinal beam. When the pressure of the baffle 3 on the longitudinal beam reaches the value set by the pressure sensor 14, the second electric push rod 11 stops running, and the operator can then perform subsequent angle correction on the left and right ends of the longitudinal beam.

[0033] Example 2

[0034] Based on Embodiment 1, a preferred embodiment of the frame longitudinal beam straightening assembly provided by this utility model is, for example... Figures 1 to 4 As shown: Angle rulers 15 are fixed on the top left and right sides of the operating table 1. Angle rulers 15 are designed with an arc shape. The center of the angle ruler 15 is concentric with the center of the rotating rod 4. A pointer 16 is fixed on the inner side of the outer wall of the connecting plate 6. The pointer 16 is located at the upper end of the angle ruler 15. The pointer 16 and the angle ruler 15 correspond to each other one by one.

[0035] In this embodiment, when the rotating top column 7 corrects the angle of the longitudinal beam, the connecting plate 6 rotates synchronously with the pointer 16 until the pointer 16 points to the value on the angle ruler 15 and meets the needs of the staff. Then the staff closes the first electric push rod 801. In this way, the angle correction status of the left and right ends of the longitudinal beam is precisely controlled within the range required by the staff.

[0036] In summary, this application, through its mechanical linkage design, can correct the angles at both ends of the longitudinal beam. The operation is convenient, time-saving, and labor-saving, not only improving worker efficiency but also ensuring the corrective effect of the longitudinal beam. The limit function design clamps and fixes the longitudinal beam placed between the limit plate and the baffle, preventing positional movement during correction and ensuring stability. The monitoring function design allows the angle correction status at both ends of the longitudinal beam to be controlled within the range required by the worker, further improving the correction effect.
