[0001] The utility model relates to the technical field of spring assembly, in particular to a spring quick assembly structure for a spring brake cylinder. Background Technique

[0002] In an automotive braking system, a spring brake cylinder is a common component, which functions to convert hydraulic pressure into mechanical force to drive a brake actuator. Springs are usually used to assist the movement of the brake cylinder. By providing a restoring force and an auxiliary thrust, the springs help ensure that the brakes can respond quickly when needed and provide stable force transmission during braking.

[0003] Currently, when assembling a spring, it is usually necessary to manually apply a certain force to compress the spring. This manual force application method not only increases the complexity and time consumption of the work, but also may increase the risk of errors by operators, reducing the assembly efficiency and work safety. For this reason, we provide a spring quick assembly structure for a spring brake cylinder. Content of the Utility Model

[0004] The utility model provides a spring quick assembly structure for a spring brake cylinder to solve the technical problem that currently when assembling a spring, it is usually necessary to manually apply a certain force to compress the spring. This manual force application method not only increases the complexity and time consumption of the work, but also may increase the risk of errors by operators, reducing the assembly efficiency and work safety as described in the above background technique.

[0005] The purpose and effect of a spring quick assembly structure for a spring brake cylinder of the utility model are achieved by the following specific technical means: A spring quick assembly structure for a spring brake cylinder includes a bottom plate. A spring seat is installed on the upper surface of the bottom plate. A moving assembly is installed above the bottom plate. The moving assembly includes two threaded cylinders rotatably connected to the upper surface of the bottom plate. A threaded rod is threadedly connected to the inner wall of each threaded cylinder.

Detailed implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As shown in the attached Figure 1 to the attached Figure 4 figures: A spring quick assembly structure for a spring brake cylinder, including a base plate 1, a spring seat 2 is installed on the upper surface of the base plate 1, and a hole diameter adapted to the size of the spring is opened on the upper surface of the spring seat 2, so that the spring can be stably placed.

[0022] A moving assembly 3 is installed above the base plate 1. The moving assembly 3 includes two threaded cylinders 301 rotatably connected to the upper surface of the base plate 1. The inner wall of each threaded cylinder 301 is threadedly connected with a threaded rod 302. The threading directions of the two threaded cylinders 301 and the two threaded rods 302 are opposite. The threaded rod 302 inside each threaded cylinder 301 is threadedly connected to the corresponding threaded cylinder 301. A driven gear 303 is fixedly connected to the outer surface of each threaded cylinder 301. The moving assembly 3 further includes a motor 304 installed on the bottom surface of the base plate 1. The output end of the motor 304 is fixedly connected with a driving gear 305. The driving gear 305 meshes with the two driven gears 303. When the driving gear 305 rotates, it will drive the two driven gears 303 to rotate in opposite directions, and at the same time, the threaded rods 302 will be lifted and lowered synchronously.

[0023] Further, in order to ensure the stable lifting and lowering of the threaded rod 302, as shown in Figure 1 and Figure 3 figures, a stabilizing plate 306 is fixedly connected to the top end of each threaded rod 302. A stabilizing hole 307 is opened on the upper surface of each stabilizing plate 306. A stabilizing rod 308 is slidably connected to the inner wall of each stabilizing hole 307. The bottom end of each stabilizing rod 308 is connected to the upper surface of the base plate 1. Through the connection between the stabilizing hole 307 and the stabilizing rod 308, the threaded rod 302 can be stabilized. When the threaded cylinder 301 rotates outside the threaded rod 302, the threaded rod 302 will be lifted and lowered stably inside the threaded cylinder 301.

[0024] Further, in order to prevent the separation between the threaded rod 302 and the threaded barrel 301, as Figure 1 and Figure 3 shown, a circular baffle 309 is fixedly connected to the bottom end of each threaded rod 302. The size of each circular baffle 309 is larger than that of the threaded barrel 301. The circular baffle 309 can be used to block the bottom end of the threaded rod 302, and it can prevent the bottom end of the threaded rod 302 from entering the inside of the threaded barrel 301.

[0025] Above the spring seat 2, a fixture assembly 4 is provided. The fixture assembly 4 includes two arc-shaped clamping plates 401. The top end of each arc-shaped clamping plate 401 is in a sealed state. The arc-shaped clamping plates 401 can be used to clamp the spring, and when the arc-shaped clamping plates 401 descend, they can also compress the spring, thus ensuring the convenience of the staff during operation.

[0026] Further, in order to improve the stability of clamping the spring, as Figure 1 and Figure 4 shown, the fixture assembly 4 further includes a U-shaped plate 402 fixedly connected to the upper surfaces of two stabilizing plates 306. A through groove 403 is formed in the upper surface of the U-shaped plate 402. Two electric push rods 404 are installed on the upper surface of the U-shaped plate 402. One ends of the two electric push rods 404 close to each other are fixedly connected to a moving plate 405. The bottom end of each moving plate 405 penetrates through the through groove 403 and is connected to the upper surface of the arc-shaped clamping plate 401. When the electric push rod 404 works, it can drive the moving plate 405. The two moving plates 405 will approach each other. At the same time, the arc-shaped clamping plates 401 will gradually surround the outside of the spring, and their top ends will form a resistance to the spring, so that the spring can be stably compressed and protected.

[0027] Working principle: When in use, first place the spring in the spring seat 2, then start the electric push rod 404 to work. The electric push rod 404 will push the arc-shaped clamping plate 401 until the arc-shaped clamping plate 401 is located directly above the spring. Then start the motor 304 to work. The motor 304 will drive the driving gear 305 to rotate. The driving gear 305 will drive the driven gear 303 to rotate. At the same time, the threaded barrel 301 will rotate outside the threaded rod 302, and the threaded rod 302 will synchronously descend and drive the arc-shaped clamping plate 401 to move downward. During the downward movement of the arc-shaped clamping plate 401, it will wrap around the outside of the spring to protect it. At the same time, the arc-shaped clamping plate 401 will compress the spring, reducing the complexity and time consumption of the work, and improving the assembly efficiency and safety.
