Description

Technical Field

[0001] This utility model belongs to the field of automotive front shock absorber assembly, and in particular relates to an automotive front shock absorber positioning mechanism. Background Technology

[0002] Automotive shock absorbers are core components of the automotive suspension system, belonging to vibration damping devices. Their main function is to attenuate vibrations caused by road impacts, improving ride comfort and handling safety. They convert mechanical energy into heat energy through hydraulic or gas damping, reducing resistance during the suspension's compression stroke to buffer impacts and increasing resistance during the extension stroke to suppress rebound, ensuring wheel grip. Therefore, in the current automotive assembly field, the quick and precise assembly of automotive shock absorbers is a crucial step. Current technologies largely rely on manual assembly, which wastes manpower and can lead to inaccurate positioning of the front shock absorbers, resulting in assembly deviations, low yield rates, and low work efficiency.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-8As shown, the automotive front shock absorber positioning mechanism includes a frame 1, a lifting assembly 2, and a positioning assembly 3. The lower end of the frame 1 is mounted on the production line. The lifting assembly 2 is mounted on one side of the frame 1, and the positioning assembly 3 is mounted on the movable end of the lifting assembly 2. The lifting assembly 2 is used to adjust the vertical position of the positioning assembly 3, and the positioning assembly 3 is used to insert and position the automotive front shock absorber. The positioning assembly is mounted on the production line via the frame 1. The positioning assembly includes a servo motor 31, a rotary table 32, a connecting shaft 33, a spring 34, and a positioning plate 35. The servo motor 31 is mounted on the movable end of the lifting assembly 2. The output shaft of the servo motor 31 is fixedly connected to the rotary table 32. Two parallel connecting shafts 33 are slidably connected inside the rotary table 32. The lower end of each connecting shaft 33 is fixedly connected to the positioning plate 35. The spring 34 is set with... Connected to the periphery of the connecting shaft 33, one end of the spring 34 abuts against the lower end of the rotary table 32, and the other end of the spring 34 abuts against the upper end of the positioning plate 35. The positioning plate 35 is provided with multiple positioning holes 351, which are used to insert the front shock absorber of the car. The servo motor 31 is existing technology, and the model of the servo motor 31 is CDQ2F40-50M. After the front shock absorber of the car is inserted, the controller is turned on, and the servo motor 31 drives the rotary table 32 to rotate, and drives the rotary table 32 below to rotate, so that the front shock absorber of the car is rotated to a predetermined angle to achieve the purpose of positioning. By setting the positioning component 3, the positioning accuracy of the front shock absorber assembly will be improved, and it is also used to replace the manual assembly of the front shock absorber of the car, so as to solve the problem of inaccurate positioning accuracy of the manual assembly of the front shock absorber of the car.

[0033] like Figure 2 As shown, the lower end of the frame 1 is provided with multiple assembly holes, and a bolt 11 is threaded into each assembly hole. The bolt 11 is used to fix the position of the frame 1. During installation, the bolt 11 is screwed into the assembly hole, and its lower end contacts the production line surface and is gradually tightened to fix the frame 1 to the production line, thereby realizing the installation and positioning of the entire positioning mechanism and ensuring that the frame 1 maintains a stable support state during operation. The bolt-fixed frame 1 enhances the stability of the overall mechanism and the connection with the production line, effectively preventing the mechanism from shaking when the lifting component 2 is running or the positioning component 3 is working. In addition, the threaded bolt 11 is easy to install, disassemble and adjust the position, and can be assembled to different production lines.

[0034] like Figure 6As shown, the positioning component 3 also includes a zero-position detection unit 36. The zero-position detection unit 36 ​​includes a scale 361, a pointer 362, a metal plate 363, and a fourth sensor 364. The pointer 362 is installed at one end of the lifting frame 22, and the scale 361 is installed on the rotating table 32. The scale 361 does not contact the pointer 362. The fourth sensor 364 is installed on one side of the lifting frame 22. One side of the rotating table 32 is connected to one end of the metal plate 363. The other end of the metal plate 363 is used to sense the actuator of the fourth sensor 364. The fourth sensor 364 is existing technology, and its model is NR. In B4-12G40, when the rotary table 32 rotates under the drive of the servo motor 31, the metal plate 363 rotates synchronously with the rotary table 32. When the metal plate 363 rotates to be opposite to the execution end of the fourth sensor 364, the fourth sensor 364 will sense the metal plate 363, thereby determining the zero position of the positioning disk 35. The cooperation between the pointer 362 and the scale 361 can intuitively display the rotation position of the rotary table 32, assisting in verifying the accuracy of the zero position. A zero position detection unit 36 ​​is set up to assist the staff in quickly verifying the zero position, ensuring the consistency and reliability of the insertion and positioning of the automotive front shock absorber, and improving assembly efficiency.

[0035] like Figure 3 As shown, the lifting assembly 2 includes a bracket 21, a lifting frame 22, a slide rail 23, a cylinder 24, and a slider 25. The bracket 21 is installed on one side of the frame 1. Two parallel slide rails 23 are fixedly installed on the bracket 21. A slider 25 is slidably connected to the periphery of each slide rail 23. One end of the slider 25 is connected to the lifting frame 22. The lower end of the lifting frame 22 is connected to the movable end of the cylinder 24. The fixed end of the cylinder 24 is installed on the bracket 21. The cylinder 24 is existing technology, and the model of the cylinder 24 is CDQ2F40-50M. When the controller is turned on, the movable end of the cylinder 24 extends, driving the lifting frame 22 to descend and abutting the positioning plate 35 against the upper end of the front shock absorber, inserting the front shock absorber into the positioning hole 351.

[0036] like Figure 4As shown, a detection unit 26 is provided on one side of the lifting frame 22. The detection unit 26 includes a first sensor 261, a second sensor 262, and a positioning piece 263. The first sensor 261 and the second sensor 262 are arranged parallel to each other and are installed on one side of the bracket 21. One end of the positioning piece 263 is installed on one side of the lifting frame 22, and the other end of the positioning piece 263 is used to sense the actuator of the first sensor 261 or the second sensor 262. The first sensor 261 and the second sensor 262 are both existing technologies, and the model of the first sensor 261 and the second sensor 262 is NRB4-12G40. Through the sensing signals of the first sensor 261 and the second sensor 262, it is possible to detect in real time whether the lifting frame 22 has reached the preset upper or lower limit position, thereby realizing precise control of the vertical displacement of the lifting frame. The detection unit 26 can detect the position of the lifting frame 22 in real time, which can ensure that the positioning component 3 can accurately reach the preset vertical height, improve positioning accuracy and assembly efficiency.

[0037] like Figure 6 As shown, a third sensor 221 is also provided on one side of the lifting frame 22. The third sensor 221 is used to detect the front shock absorber of the car in the positioning hole 351. The third sensor 221 is existing technology. The model of the third sensor 221 is NRB4-12G40. The third sensor 221 is used to detect whether the front shock absorber has been inserted into the hole 351.

[0038] Working process of the car front shock absorber positioning mechanism:

[0039] The frame 1 is fixed to the production line by mounting holes at the lower end and bolts 11. The movable end of the cylinder 24 extends and retracts. The zero position of the positioning plate 35 is determined by the fourth sensor 364 and the scale 361. The controller is turned on, and the controller controls the movable end of the cylinder 24 to extend, so that the positioning plate 35 is abutted against the upper end of the front shock absorber. The front shock absorber is inserted into the positioning hole 351. After the insertion is completed, the servo motor 31 drives the rotary table 32 to rotate, which drives the connecting shaft 33 and the positioning plate 35 to rotate synchronously, rotating the front shock absorber to the required angle.

[0040] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
