Description

Technical Field

[0001] This utility model relates to the field of stabilizer bar testing technology, and in particular to a device for testing stabilizer bars after bending. Background Technology

[0002] In the manufacturing process of stabilizer bars, the bending process is one of the core processing steps. It is necessary to strictly control geometric parameters such as bending angle and bending distance, and at the same time ensure that there are no defects such as cracks, dents, and scratches on the multiple surfaces after bending in order to meet product quality standards.

[0003] Existing methods for inspecting balance bars after bending typically rely on manual measuring tools such as vernier calipers and angle gauges. Operators measure the bending angle and distance point by point and record the data. This method is inefficient, and when inspecting surface defects on the balance bar, it is necessary to manually flip the balance bar to complete the inspection of surface defects on multiple sides of the balance bar, which is cumbersome and inconvenient.

[0004] Therefore, it is necessary to design a post-bending inspection device for balance bars that can detect bending angles, bending distances, and multi-faceted surface defects, is easy to operate, and improves inspection efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing methods for inspecting balance bars after bending, which typically rely on manual measuring tools such as vernier calipers and angle gauges, requiring operators to measure and record bending angles and distances point by point, this method is inefficient. Furthermore, when inspecting surface defects on the balance bar, it is necessary to manually flip the balance bar to complete the inspection of surface defects on multiple sides, which is quite cumbersome. This invention provides a balance bar bending inspection device that can inspect the bending angle, bending distance, and surface defects on multiple sides of the balance bar, which is simple to operate and improves inspection efficiency.

[0006] The technical solution is as follows: A device for detecting the bending of a balance bar includes an inspection table, a movable frame, a fixed plate, a guide frame, a first spring, a cylinder, a connecting frame, visual inspection heads, and a pushing assembly. The movable frame is slidably connected to both the front and rear parts of the inspection table, and the balance bar is placed between the movable frames. A fixed plate is connected to the upper side of the middle part of the inspection table. Guide frames are slidably connected to the sides of the movable frames that are far apart from each other. A first spring is connected to the left and right parts of the guide frame and the adjacent movable frame. A cylinder is connected to the front part of the inspection table. The cylinder and the processor are electrically connected through a control module. A connecting frame is connected to the telescopic end of the cylinder. The connecting frame is slidably connected to the inspection table. Two visual inspection heads are connected to the upper inner side of the connecting frame. Each movable frame is equipped with a pushing assembly that can push the balance bar to rotate.

[0007] Furthermore, the inspection table is equipped with two anti-slip pads on the front and back sides.

[0008] Furthermore, it also includes a two-way lead screw and a knob. The two-way lead screw is rotatably connected to the upper left of the inspection table, and a knob is connected to the rear side of the two-way lead screw.

[0009] Furthermore, the knob has anti-slip texture.

[0010] Furthermore, a limit block is provided in the middle of the bidirectional lead screw.

[0011] Furthermore, the pushing component includes a guide block, a second spring, and a trigger frame. The guide blocks are slidably connected to the opposite sides of the right side of the moving frame. The guide blocks are connected to the adjacent moving frames by a second spring. The trigger frames are slidably connected to both the front and rear parts of the connecting frame. The trigger frames are in contact with the adjacent guide blocks and moving frames.

[0012] The beneficial effects of this utility model are as follows: This utility model determines the bending angle by checking whether the balance bar can be placed between the moving frames and whether the balance bar is parallel to the moving frames at the bend. It determines the bending distance by observing the distance between the balance bar and the guide frame. The balance bar is flipped by the pressure of the guide block. The visual inspection head detects surface defects of the balance bar. This achieves the effect of detecting the bending angle, bending distance and multi-faceted surface defects of the balance bar. The operation is simple and the detection efficiency is improved. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] A device for detecting the bending of a balance bar, such as Figures 1-4As shown, the system includes an inspection table 1, a movable frame 4, a fixed plate 5, a guide frame 6, a first spring 7, a cylinder 8, a connecting frame 9, a visual inspection head 10, and a pushing assembly. The inspection table 1 has two anti-slip pads on its lower side. The movable frame 4 is slidably connected to both the front and rear parts of the inspection table 1. A balance bar 0 is placed between the movable frames 4. The fixed plate 5 is connected to the upper middle part of the inspection table 1. The guide frame 6 is slidably connected to the opposite sides of the movable frames 4. The first spring 7 is connected to the left and right parts of the guide frame 6 and the adjacent movable frame 4. The cylinder 8 is connected to the front part of the inspection table 1. The cylinder 8 and the processor are electrically connected through a control module. The connecting frame 9 is connected to the telescopic end of the cylinder 8. The connecting frame 9 is slidably connected to the inspection table 1. The left and right visual inspection heads 10 are connected to the upper inner side of the connecting frame 9. The movable frame 4 is equipped with a pushing assembly.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the pushing assembly includes a guide block 11, a second spring 12, and a trigger frame 13. The guide blocks 11 are slidably connected to the opposite sides of the right side of the moving frame 4. The guide blocks 11 are connected to the adjacent moving frames 4 by the second spring 12. The trigger frames 13 are slidably connected to the front and rear parts of the connecting frame 9. The trigger frames 13 are in contact with the adjacent guide blocks 11 and the moving frame 4.

[0021] When using this device, first place the inspection table 1 in the inspection area after the balance bar 0 is bent, then place the balance bar 0 between the moving frames 4, so that the balance bar 0 contacts the fixed plate 5. When the bends at both ends of the balance bar 0 are less than 90 degrees, the balance bar 0 cannot be secured between the moving frames 4. When the balance bar 0 is placed between the moving frames 4, you can observe whether the two ends of the balance bar 0 are parallel to the moving frames 4 to determine whether the bends at both ends of the balance bar 0 are greater than 90 degrees. After the balance bar 0 is placed between the moving frames 4, the two ends of a qualified balance bar 0 will contact the guide frame 6. When the bend distances at both ends of the balance bar 0 are inconsistent, you can judge by observing the distance between the balance bar 0 and the guide frame 6. When it is necessary to inspect the surface defects of the balance bar 0... During inspection, cylinder 8 can be activated to move connecting frame 9 to the left. First, the surface of balance bar 0 is inspected through the left visual inspection head 10. When connecting frame 9 moves, it will drive trigger frame 13 to move. When connecting frame 9 moves a certain distance, trigger frame 13 will press guide block 11, causing guide block 11 to move to the left. Second spring 12 retracts, and through guide block 11, it pushes balance bar 0, causing balance bar 0 to flip. The surface of balance bar 0 is inspected again through right visual inspection head 10. When balance bar 0 flips, it will press guide frame 6 to move downward, and first spring 7 retracts. This allows for the inspection of balance bar 0's bending angle, bending distance, and multi-faceted surface defects. The operation is simple and improves inspection efficiency.

[0022] like Figure 1 and Figure 2 As shown, it also includes a bidirectional lead screw 2 and a knob 3. The bidirectional lead screw 2 is rotatably connected to the upper left of the inspection table 1. A limit block is provided in the middle of the bidirectional lead screw 2. A knob 3 is connected to the rear side of the bidirectional lead screw 2. The knob 3 is provided with anti-slip texture for easy gripping.

[0023] When it is necessary to test balance bars 0 of different lengths, the knob 3 can be turned to drive the bidirectional lead screw 2 to rotate, so that the moving frame 4 moves under the action of the screw, so that the moving frames 4 move away from each other to adjust the distance between them. At the same time, the moving frame 4 pushes the trigger frame 13 to slide, thereby adjusting the distance between the moving frames 4, which is convenient for testing balance bars 0 of different lengths.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
