[0021] 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.

[0022] Please see Figure 1-4 The spring-pressing device in this embodiment includes a device body 1, a pressure-receiving platform 2 fixedly installed inside the device body 1, and a spring fixing mechanism 3 provided inside the pressure-receiving platform 2;

[0023] The spring fixing mechanism 3 includes a first bearing 301 and a second bearing 302. A set of first bearings 301 and a set of second bearings 302 are fixedly installed inside the pressure table 2. Each set of first bearings 301 and second bearings 302 consists of two bearings. A bidirectional threaded rod 303 extending to the front exterior of the pressure table 2 is fixedly connected to the inner wall of the first bearing 301. A handwheel 304 is provided at the extension point of the bidirectional threaded rod 303 to the front exterior of the pressure table 2. First, rotating the handwheel 304 allows it to drive the first bearing 301. The bidirectional threaded rod 303 on bearing 01 rotates stably. A set of bearings 302 has a bidirectional threaded rod 305 fixedly connected to its inner wall. The two threads on the bidirectional threaded rod 303 are symmetrical, and the two threads on the bidirectional threaded rod 305 are also symmetrical. A driving gear ring 306 is fixedly mounted on the bidirectional threaded rod 303, and a driven gear ring 307 connected to the driving gear ring 306 is fixedly mounted on the bidirectional threaded rod 305. The teeth on the driving gear ring 306 and the driven gear ring... The teeth on 307 are mutually adapted, and their connection is an meshing connection. By setting a driving gear ring 306 and a driven gear ring 307, the bidirectional threaded rod 303 rotates stably while the bidirectional threaded rod 305 rotates synchronously and stably. Threaded sleeves 308 are threadedly connected to the front and rear outer walls of the bidirectional threaded rod 303 and the left and right outer walls of the bidirectional threaded rod 305. A limiting rod 3 extending to the outside of the pressure table 2 is fixedly installed at the top of each threaded sleeve 308. 09, where the pressure table 2 has four limiting grooves in a cross shape, and the four limiting grooves are respectively adapted to the four limiting rods 309. The inner wall of the limiting groove is slidably connected to the outer wall of the limiting rod 309. Finally, by setting threaded sleeves 308 and limiting rods 309, when the two bidirectional threaded rods are rotating stably, the two threaded sleeves 308 and the two limiting rods 309 on each rod can move close to or far apart, thus better adapting to springs of different diameters. It has strong practicality and applicability.

[0024] In the implementation of the case, a hydraulic telescopic machine 4 is fixedly installed on the inner top wall of the main body of the equipment 1. A pressure plate 5 is fixedly connected to the telescopic end of the hydraulic telescopic machine 4. A positioning post 6 and a flexible pad 7 are provided at the bottom of the pressure plate 5. The positioning post 6 can be inserted into the inside of the spring 11 when the hydraulic telescopic machine 4 is running. This design can ensure that the spring will not deform when it is squeezed, while the flexible pad 7 can minimize the damage to the spring caused by the equipment during compression.

[0025] In the case implementation, guide rods 8 are fixedly installed inside the main body 1 and on both sides of the pressure table 2. The two guide rods 8 are slidably connected to the inner walls of the left and right sides of the pressure plate 5 respectively. This design can effectively ensure the verticality of the pressure plate 5 when it moves up and down, and avoid the plate shaking from affecting the processing quality.

[0026] In the implementation of the case, a pressure measuring device 9 is installed on the pressure table 2. This design can effectively record the pressure applied by the equipment so as to make timely adjustments. A controller 10 is installed on the front side of the main body 1. The controller 10 and the electronic components in this patent are electrically connected through wires, so as to facilitate the operation of the controller 10 to control the operation of the electronic components. The four limit rods 309 are externally clamped with springs 11. The springs 11 can be any model or specification.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, rotate the handwheel 304 so that the handwheel 304 can drive the bidirectional threaded rod 303 on the bearing 301 to rotate stably;

[0029] 2) Then, by setting the driving gear ring 306 and the driven gear ring 307, the bidirectional threaded rod 1 303 can rotate stably while the bidirectional threaded rod 2 305 can also rotate stably in sync.

[0030] 3) Finally, by setting threaded sleeves 308 and limiting rods 309, when both bidirectional threaded rods rotate stably, the two threaded sleeves 308 and the two limiting rods 309 on each rod can move close to or far apart, thus better adapting to springs of different diameters.

[0031] In summary, this spring-pressurizing device, by setting up a spring fixing mechanism 3, firstly rotates the handwheel 304, which drives the bidirectional threaded rod 303 on the bearing 301 to rotate stably. Then, by setting up a driving gear ring 306 and a driven gear ring 307, the bidirectional threaded rod 305 can also rotate stably at the same time as the bidirectional threaded rod 303. Finally, by setting up threaded sleeves 308 and limiting rods 309, when both bidirectional threaded rods are rotating stably, the two threaded sleeves 308 and the two limiting rods 309 on each rod can move close to or far apart, thus better adapting to springs of different diameters. It has strong practicality and applicability, solving the problem that the limit components of the device have too low adjustability, resulting in the inability to adapt to springs of different diameters.
