Description

Technical Field

[0001] This utility model relates to the field of automotive spring technology, specifically a limiting device for automotive spring processing. Background Technology

[0002] Automotive springs are key elastic components in automotive suspension systems, primarily functioning to absorb road impacts through deformation, transmit vertical loads, and maintain vehicle stability. Their structure and function vary depending on the type and application. During automotive spring manufacturing, to prevent positional shifts, a limiting device is needed to restrict the spring's position. Existing technology, patent publication number CN 220613680 U, proposes a limiting device for automotive spring manufacturing, comprising: a base plate, a connecting plate mounted on the upper part of the base plate, a top plate above the base plate, a motor mounted at the bottom of the top plate, and a threaded post connected to the motor's output shaft. The threaded post has two symmetrically arranged external threads with opposite directions. A first mounting plate is threaded onto one of the external threads of the threaded post. While this device can limit the movement of automotive springs, it requires pre-adjustment based on the spring's dimensions when limiting springs of different lengths or inner diameters, resulting in a longer time requirement.

[0014] 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.

[0015] Please see Figure 1-5 This embodiment provides a technical solution: a limiting device for processing automotive springs, including a housing 1, which provides space for setting automotive spring limiting components; Housing 1: Its front surface is provided with grooves 2. Each groove 2 is slidably connected to a limiting rod 3. By sliding the limiting rod 3 in the groove 2, the three limiting rods 3 open outwards simultaneously, limiting the left-right and up-down positions of the car spring. Each limiting rod 3 has a limiting plate 4 at its front end. The limiting rod 3 drives the limiting plate 4 to move backward, so that the limiting plate 4 cooperates with the front surface of housing 1 to limit the front-back position of the car spring. Each limiting rod 3 has a longitudinally slidably connected elastic limiting detection plate 5 at its rear end. By detecting the position of detection plate 5, it is determined whether the front-back limiting of the car spring is accurate. Each limiting rod 3 has an elastic limiting detection plate 6 on its outer arc surface. By detecting the position of detection plate 6, it is determined whether the limiting of the car spring is accurate. A microcontroller 10 is provided on the side of the housing 1. The input terminal of the microcontroller 10 is electrically connected to an external power supply to control the start and stop of the entire device. An adjusting shell 7 is longitudinally slidably connected inside the housing 1. An adjusting disc 8 is rotatably connected inside the adjusting shell 7. A connecting slider 9 is provided at the rear end of each limiting rod 3. The connecting slider 9 is slidably connected to the clearance groove on the front surface of the adjusting shell 7. The slider strip at the rear end of the connecting slider 9 is slidably connected to the plane spiral groove on the front surface of the adjusting disc 8. A motor 11 is provided on the rear side of the adjusting shell 7. The output shaft of the motor 11 is fixedly connected to the middle of the adjusting disc 8. The input end of the motor 11 is electrically connected to the output end of the microcontroller 10. When the motor 11 is started, the output shaft of the motor 11 drives the adjusting disc 8 to rotate. The slider strip of the connecting slider 9 slides in the plane spiral groove of the adjusting disc 8, which drives the connecting slider 9 to slide in the clearance groove on the front surface of the adjusting shell 7, so that the three limiting rods 3 open outward synchronously and with the same amplitude. Guide posts 12 are provided between the front and rear inner walls of the housing 1. The guide posts 12 are longitudinally slidably connected to the guide holes on the outer edge of the adjusting housing 7. Electric push rods 13 are provided at the rear end of the housing 1. The front end of the telescopic end of the electric push rod 13 is fixedly connected to the adjusting housing 7. The input end of the electric push rod 13 is electrically connected to the output end of the microcontroller 10. When the electric push rod 13 is started, the telescopic end of the electric push rod 13 drives the adjusting housing 7 to move backward. Through the connection of the slider 9 and the clearance groove on the front surface of the adjusting housing 7, the three limit rods 3 move backward synchronously. Under the guidance and support of the guide posts 12, the radial force on the telescopic end of the electric push rod 13 is avoided from being easily damaged. Sliding frames 14 are slidably connected inside the sliding groove 2. Limiting rods 3 are slidably connected longitudinally inside the sliding frames 14. Sliding columns 15 are slidably connected longitudinally in the sliding holes on the surface of the sliding frames 14. Detection plates 15 are respectively set between the front ends of the two sliding columns 15 of the same sliding frame 14. Contact sensors 17 are provided on the surface of the sliding frame 14 to cooperate with the detection plates 15. The output end of the contact sensor 17 is electrically connected to the input end of the microcontroller 10. Springs 16 are provided between the limiting plate at the rear end of the sliding column 15 and the sliding frame 14. The springs 16 are movably sleeved on the outer arc surface of the sliding column 15. The limiting plate 4 pushes the car spring to move backward until the car spring contacts the detection plate 15. As the car spring continues to move backward, the car spring deforms (when the friction between the car spring and the limiting rod 3 is large, the movement of the limiting rod 3 will drive the car spring to move together, and when the car spring contacts the detection plate 15...). After contact with spring 16, the detection plate 15 pushes the car spring and the limit rod 3 to move relative to each other until the car spring contacts the limit plate 4. The limit plate 4 then pushes the car spring to deform. Under the action of the car spring's elastic force, the elastic force of spring 16 is overcome, and the detection plate 15 is pushed to move backward until the detection plate 15 contacts the detection end of the contact sensor 17. The contact sensor 17 sends a signal to the microcontroller 10, and the microcontroller 10 controls the electric push rod 13 to stop. At this time, the detection plate 15 contacts the front surface of the sliding frame 14. Through the cooperation of the detection plate 15 and the limit plate 4, the front and rear positions of the car spring are restricted. The front end of the spring 16 is connected to the sliding frame 14 through connecting bolt 1, and the rear end of the spring 16 is connected to the sliding column 15 through connecting bolt 2. The connecting bolts are rotated periodically to disassemble the spring 16 for replacement or maintenance to ensure the normal operation of the spring 16. The cross-section of each limiting rod 3 is fan-shaped. Each limiting rod 3 has a contact sensor 2 19 installed in the groove of its outer arc surface. Detection plates 2 6 are respectively installed at the detection end of the contact sensor 2 19. Rubber pads 18 are installed between the outer side of the detection plate 2 6 and the inner wall of the groove of the limiting rod 3. The output end of the contact sensor 2 19 is electrically connected to the input end of the microcontroller 10. When the outer arc surface of the limiting rod 3 contacts the car spring, the car spring applies a reaction force to the detection end of the contact sensor 2 19 through the detection plate 2 6. The contact sensor 2 19 sends a signal to the microcontroller 10, and the microcontroller 10 controls the motor 11 to stop. At this time, all three limiting rods 3 are in contact with the car spring, restricting the left and right movement and the up and down movement of the car spring.

[0016] The working principle of the limiting device for automotive spring processing provided by this utility model is as follows: During the automotive spring processing, the automotive spring is directly sleeved on the outer side of the integral structure composed of three limiting rods 3. Then, the motor 11 is started by the microcontroller 10. The output shaft of the motor 11 drives the adjusting plate 8 to rotate. The slider of the connecting slider 9 slides in the planar spiral groove of the adjusting plate 8, driving the connecting slider 9 to slide in the clearance groove on the front surface of the adjusting shell 7. The three limiting rods 3 open outward synchronously and with the same amplitude. The sliding frame 14 slides in the groove 2. When the outer arc surface of the limiting rod 3 contacts the automotive spring, the automotive spring applies a reaction force to the detection end of the contact sensor 19 through the detection plate 2 6. The contact sensor 19 sends a signal to the microcontroller 10, and the microcontroller 10 controls the motor 11 to stop. At this time, all three limiting rods 3 are in contact with the automotive spring, restricting the left and right movement and the up and down movement of the automotive spring. Then, the motor 11 is started. The push rod 13, through its telescopic end, drives the adjusting shell 7 to move backward. It then slides vertically along the clearance groove on the front surface of the adjusting shell 7 via the connecting slider 9, causing the three limiting rods 3 to move backward synchronously. The limiting rods 3 slide relative to the sliding frame 14, using the limiting plate 4 to push the car spring backward until it contacts the detection plate 5. As the car spring continues to move backward, it deforms, overcoming the elasticity of the spring 16 under its own force, pushing the detection plate 5 backward until it contacts the detection end of the contact sensor 17. The contact sensor 17 sends a signal to the microcontroller 10, which then controls the electric push rod 13 to stop. At this point, the detection plate 5 contacts the front surface of the sliding frame 14. Through the cooperation of the detection plate 5 and the limiting plate 4, the front and rear positions of the car spring are restricted, quickly limiting car springs of different lengths and inner diameters.

[0017] It is worth noting that the microcontroller 10 disclosed in the above embodiments can be an STM32F107 microcontroller. The motor 11, electric actuator 13, contact sensor 17 and contact sensor 19 can be freely configured according to the actual application scenario. The motor 11 can be a 3M57-42A stepper motor, the electric actuator 13 can be a LAM1 electric actuator, and both contact sensor 17 and contact sensor 19 can be AG-410 contact pressure sensors. The microcontroller 10 controls the operation of the motor 11, electric actuator 13, contact sensor 17 and contact sensor 19 using methods commonly used in the prior art.
