Description

Technical Field

[0001] This utility model relates to the technical field of automotive suspension torsion bar correction equipment, specifically an automotive suspension torsion bar bending correction device. Background Technology

[0002] The torsion bar in an automotive suspension is a mechanism connecting the wheels to the vehicle body, providing support and damping. Its primary function is to transmit forces between the wheels and the chassis, and to cushion impacts from uneven road surfaces, thus attenuating vibrations and ensuring a smooth ride. However, errors may occur during the manufacturing process of automotive suspension torsion bars, causing them to bend. This can severely affect product quality and performance, and may even pose safety hazards during use. Therefore, the bend of automotive suspension torsion bars must be inspected and corrected before leaving the factory.

[0003] Chinese patent CN219442981U provides a device for correcting the curvature of an automotive torsion bar, including a processing table with placement racks on both sides. The placement racks contain the torsion bar body. However, the distance between the placement racks cannot be adjusted. If a torsion bar with an irregular size is encountered, a specific device is required for correction, which is not conducive to improving the practicality of the device. Furthermore, the above setup only uses a straightening wheel to fix the torsion bar. If a torsion bar with a large curvature is encountered, repeated correction is required, which takes a long time and is not conducive to improving the working efficiency of the device.

[0004] Therefore, this utility model provides a device for correcting the bending of a torsion bar in an automotive suspension to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automotive suspension torsion bar bending correction device. By driving a first electric motor to rotate, it moves one of the fixing mechanisms, facilitating the fixing of torsion bars of different lengths and diameters, thus improving the applicability of the device. By incorporating a movable intelligent heater to heat the torsion bar, the strength of the torsion bar is reduced, which helps to shorten the correction time and solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a torsion bar bending correction device for automobile suspension, comprising a worktable, two sets of fixing mechanisms arranged above the worktable, an L-shaped sliding plate slidably connected to one end of the worktable, a first reciprocating lead screw mounted on the worktable, a threaded block threadedly connected to the first reciprocating lead screw, the threaded block being slidably connected to the worktable, and one set of fixing mechanisms being fixedly connected to the threaded block.

Detailed Implementation

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0018] Please see Figure 1-4 A torsion bar bending correction device for automotive suspension includes a worktable 1. Two sets of fixing mechanisms 5 are arranged above the worktable 1. An L-shaped slide plate 6 is slidably connected to one end of the worktable 1. A first reciprocating screw 3 is installed on the worktable 1. A threaded block 4 is threadedly connected to the first reciprocating screw 3. The threaded block 4 is slidably connected to the worktable 1. One set of fixing mechanisms 5 is fixedly connected to the threaded block 4. By driving the first reciprocating screw 3 to rotate, the threaded block 4 is driven to reciprocate along the worktable 1, which in turn drives the fixing mechanism 5 to slide along the worktable 1. The distance between the two sets of fixing mechanisms 5 can be adjusted, so that the device can fix torsion bars of various lengths. The two sets of fixing mechanisms 5 include a fixing block 501, a rotating block 502 rotatably connected to the fixing block 501, an electric telescopic rod 503 fixedly connected to the rotating block 502, an arc-shaped clamping plate 504 fixedly connected to the bottom end of the electric telescopic rod 503, and a rubber pad fixedly connected to the bottom end of the arc-shaped clamping plate 504; the electric telescopic rod 503 is fixedly connected to an external power source, and the electric telescopic rod 503 can be controlled by a PLC. By driving the electric telescopic rod 503 to move the arc-shaped clamping plate 504 in the vertical direction, the torsion bar is fixed. A rubber pad is provided at the bottom of 504, and a rubber pad is fixedly connected to the inner wall of the rotating block 502. This facilitates the increase of friction between the torsion bar and the rotating block 502, prevents the position of the torsion bar from shifting, and helps prevent the arc-shaped clamp 504 from damaging the outer wall of the torsion bar. The rotating block 502 has a through hole, making this device suitable for torsion bars of various lengths. Several sets of evenly distributed pressure sensors are embedded in the arc-shaped clamp 504 to provide real-time feedback on the clamping status of the torsion bar to the PLC. The PLC automatically adjusts the force of the electric telescopic rod 503 to ensure that the position of the bent torsion bar does not shift when it rotates. Another set of fixing mechanisms 5 is fixedly connected to the workbench 1. A second electric motor 11 is fixedly connected to the fixing mechanism 5. A drive gear 12 is fixedly connected to the output end of the second electric motor 11. The drive gear 12 meshes with a driven gear 13. The driven gear 13 is fixedly connected to the rotating block 502. The second electric motor 11 is controlled by a PLC and is fixedly connected to an external power supply. By driving the second electric motor 11 to rotate, the drive gear 12 rotates. The drive gear 12 meshes with the driven gear 13 to rotate, which in turn drives the rotating block 502 to rotate, thereby driving the torsion bar to rotate, which facilitates the correction of the torsion bar. A first electric motor 2 is fixedly connected to the workbench 1. The output end of the first electric motor 2 is fixedly connected to the first reciprocating lead screw 3. The other end of the first reciprocating lead screw 3 is rotatably connected to the workbench 1. The first electric motor 2 is fixedly connected to an external power supply. The first electric motor 2 is controlled by a PLC. By driving the first electric motor 2 to rotate, the first reciprocating lead screw 3 is driven to rotate.

[0019] In this embodiment, the first electric motor 2 is driven to rotate, which in turn drives the first reciprocating lead screw 3 to rotate. The rotation of the first reciprocating lead screw 3 drives the fixing mechanism 5 to slide along the worktable 1, thereby adjusting the distance between the two sets of fixing mechanisms 5. This allows the device to fix torsion bars of various lengths. The electric telescopic rod 503 is driven to move the arc-shaped clamp 504 in the vertical direction to fix the torsion bar. During correction, the second electric motor 11 is driven to rotate, which drives the drive gear 12 to rotate. The drive gear 12 meshes with the driven gear 13 to rotate, which drives the rotating block 502 to rotate, thereby driving the torsion bar to rotate, which facilitates the correction of the torsion bar. Example 2:

[0020] Please see Figure 1-3 This embodiment provides a technical solution based on embodiment one: a third electric motor 16 is fixedly connected to the workbench 1, and a second reciprocating screw 17 is fixedly connected to the output end of the third electric motor 16. The other end of the second reciprocating screw 17 is rotatably connected to the workbench 1. The second reciprocating screw 17 is threadedly connected to the L-shaped slide plate 6. The third electric motor 16 is controlled by a PLC and is fixedly connected to an external power supply. By driving the third electric motor 16 to rotate, the second reciprocating screw 17 is driven to rotate, and the rotation of the second reciprocating screw 17 drives the L-shaped slide plate 6 to slide along the workbench 1. The bottom end of the L-shaped sliding plate 6 is fixedly connected to a first cylinder 7 and a second cylinder 9. The bottom end of the first cylinder 7 is fixedly connected to a mounting block 8, which has a mounting groove. Four sets of electric push rods 14 are fixedly connected to the mounting groove, and a straightening wheel 15 is fixedly connected to the output end of each set of electric push rods 14. The bottom end of the second cylinder 9 is fixedly connected to a smart heater 10. The first cylinder 7 and the second cylinder 9 are controlled by a PLC and are fixedly connected to an external power source. This allows the device to adjust the height of the mounting block 8 and the smart heater 10 according to the height of the torsion bar. The smart heater 10 is fixedly connected to an external power source and its temperature can be controlled by a PLC to heat the torsion bar, which helps improve the correction efficiency of the device. The four sets of electric push rods 14 are interconnected and controlled by a single PLC signal to ensure uniform distribution of the correction force. The electric push rod 14 is fixedly connected to an external power source. By setting four sets of electric push rods 14 on the mounting block 8, the distance between the straightening wheels 15 can be adjusted, making it easy to fit the outer wall of the torsion bar for correction. A mounting plate 18 is fixedly connected to the front center of the mounting block 8, and an infrared temperature sensor 19 is fixedly connected to the mounting plate 18. The infrared temperature sensor 19 is fixedly connected to an external power source. The infrared temperature sensor 19 feeds back the measured temperature to the PLC system, which adjusts the power of the intelligent heater 10 and the height of the second cylinder 9 in real time according to the correction requirements, so as to facilitate heating the outer wall of the torsion bar. The intelligent heater 10 can switch between heating and cooling modes. Heating softens the torsion bar before correction. After correction, the PLC switches to cooling mode according to the data from the infrared temperature sensor 19, so that the torsion bar can be quickly solidified, shortening the correction cycle.

[0021] In this embodiment, by setting an intelligent heater 10 at the front end of the mounting block 8, it is convenient to heat the torsion bar before correction. The correction effect is better after heating, which helps to reduce correction time and improve the correction efficiency of the equipment. By driving the electric push rod 14, the distance between the straightening wheels 15 can be adjusted, which makes it easy to fit the outer wall of the torsion bar for correction. By driving the third electric motor 16 to rotate, the second reciprocating lead screw 17 is rotated. The rotation of the second reciprocating lead screw 17 drives the L-shaped slide plate 6 to slide along the worktable 1, which facilitates the correction of the torsion bar.
