The driving member 103 is controlled to drive the compression plate 102 to return, and the pressing structure 1 is taken out from the installation cavity 9, and the springs 5 ​​on other mold vehicles are continued to be pressed. By matching the pressing structure 1 with a narrow space, the spring 5 in the narrow space is automatically compressed, and there is no need to manually compress the spring 5, which can improve the installation efficiency and reduce the labor intensity of the installer.

[0045] It should be noted that the locking nut 8 is threadedly connected to the spring rod 6, the locking nut 8 and the spring rod 6 are both located in the avoidance space, and the spring 5 is a crank arm spring on the mold car.

[0046] In one embodiment, the compression plate 102 has a mating portion mating with the spring disk 7 on one side facing away from the mounting plate 101. After the press-fit structure 1 is placed in the mounting cavity 9, the spring disk 7 is mated with the compression plate 102, and the driving member 103 is started, and the compression plate 102 drives the spring disk 7 to move, and then the spring 5 is compressed by the spring disk 7, which is more convenient for compressing the spring.

The compression plate 102 is provided with a guide hole. One end of the guide column 105 is fixed on the mounting plate 101, and the other end of the guide column 105 passes through the guide hole and is fixedly connected to the guide plate 104.

[0056] Furthermore, the fixing plate 106 is fixed to the mounting plate 101 and the guide plate 104 by welding, and welding makes the connection between the fixing plate 106 and the mounting plate 101 and the guide plate 104 more firm and reliable, thereby enhancing the structural stability.

[0057] In one embodiment, two fixing plates 106 are provided and located on both sides of the avoidance space.

[0058] Furthermore, the bottom surfaces of the mounting plate 101 and the guide plate 104 are fixed on the top surface of the fixing plate 106, and the fixing plate 106 is arranged horizontally, and the press-fit structure 1 is placed in the mounting cavity 9. The fixing plate 106 is supported on the bottom wall of the mounting cavity 9, so that the press-fit structure 1 is more stable during press-fitting.

[0059] In another embodiment, the fixing plate 106 may also be arranged vertically, and the vertical edges of the mounting plate 101 and the guide plate 104 are fixed on the vertical surface of the fixing plate 106 .

[0061] In one embodiment, the driving member 103 is a hydraulic cylinder, and the spring pressing device further includes a hydraulic assembly 3 and an electrical control box, which are arranged on the mobile trolley 2, the hydraulic assembly 3 is connected to the hydraulic cylinder, and the electrical control box is electrically connected to the hydraulic assembly 3. The hydraulic assembly 3 provides a hydraulic source for the hydraulic cylinder, and the electrical control box controls the hydraulic pump, solenoid valve, etc. in the hydraulic assembly 3. During compression, the electrical control box controls the hydraulic assembly 3, and then controls the hydraulic cylinder to compress the spring 5. The hydraulic cylinder is small in size and can be arranged in a narrow space.

[0062] Furthermore, the hydraulic assembly 3 includes an oil tank, a hydraulic pump, a solenoid valve, etc. The hydraulic pump is connected to the oil tank, and the hydraulic pump is connected to the hydraulic cylinder through the solenoid valve. The hydraulic assembly can also be called a hydraulic station.

[0063] Furthermore, one end of the hydraulic cylinder is fixed to the mounting plate 101 by means of bolts, and the other end of the hydraulic cylinder is threadedly connected to the compression plate 102 by means of the thread of the piston rod.

[0065] In one embodiment, the number of the driving members 103 is at least two, and the at least two driving members 103 are disposed on both sides of the second avoidance opening 1021. The at least two driving members 103 compress the spring 5 at the same time, thereby increasing stability.

[0066] The working process of the spring pressing device is described below:

[0067] During operation, the press-fitting structure 1 is placed at the installation position of the crank arm spring of the mold vehicle so that the semicircular groove 1022 on the compression plate 102 overlaps with the spring disk 7; the hydraulic system formed by the hydraulic assembly 3 and the hydraulic cylinder is started, the hydraulic cylinder pushes the compression plate 102, and the thrust acting on the compression plate 102 pushes the spring disk 7, and the spring disk 7 plays the role of compressing the spring 5; when the spring 5 is compressed to the set position, the hydraulic cylinder stops automatically, and the hydraulic system maintains pressure; the circular locking nut 8 is screwed so that the locking nut 8 is in a fit with the spring disk 7; the hydraulic system releases pressure, and the hydraulic cylinder returns to its position, completing the press-fitting, and then the press-fitting structure 1 is taken out from the installation cavity 9, and the springs 5 ​​on other mold vehicles are continued to be press-fitted.

[0068] In the related art, spring pressing usually adopts mechanical thread compression and drive compression rod compression. When the drive compression rod is used for compression, the spring pressing device includes a frame, a drive module, a compression measurement module, etc. The drive module includes a compression rod and a drive mechanism for driving the compression rod. The device has the following problems:

[0069] 1. Only closed spring structures can be pressed, and open spring structures cannot be compressed;

[0070] 2. The fixed platform takes up a large space and has poor mobility, which cannot meet the needs of multi-station use;

[0071] 3. It can only press-fit spring structures without space restrictions, and cannot meet the needs of spring press-fitting in narrow spaces.

[0072] In order to solve the above problems, in the present embodiment, the spring structure pressed by the spring pressing device is open. According to the size of the space where the spring 5 is located, a special pressing structure 1 is designed to match the narrow space. The spring rod 6 is avoided by the avoidance space of the pressing structure 1. When pressing the spring 5, the pressing structure 1 is directly placed in the installation cavity 9 for installing the spring 5, so that the spring 5 can be automatically compressed in the narrow space; a semicircular groove 1022 is designed to limit the spring disk 7, the spring disk 7 cannot pass, and the circular locking nut 8 can pass. During the pressing process of the spring 5, the spring 5 to be compressed can be prevented from moving or detaching. At the same time, the spring disk 7 coincides with the semicircular groove 1022, so that the hydraulic cylinder compresses the spring 5 horizontally, thereby increasing the compression stability; dual cylinders are used for direct and simultaneous pressing to increase stability, and at the same time, the cylinders are small in size, which meets the requirements of narrow space layout; a movable trolley 2 is designed, and the device as a whole can be moved and used, and the platform design is removed, that is, the movable trolley 2 replaces the installation platform, which has good maneuverability.
