Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a fixing tool for cutting a wave spring. Background Art

[0002] Although the spring industry is a small industry in the entire manufacturing industry, its role should never be underestimated. Wave spring is one of the types of springs. In the production and processing of springs, steel wire is usually used to process the spring into a spiral coil. After the spring is formed, it needs to be cut and segmented into equidistant finished springs to meet customer needs.

[0003] However, during the existing spring cutting process, there is no corresponding clamping mold to limit and fix the spring, which makes the spring easily misplaced during cutting, resulting in cutting errors. Therefore, in order to strengthen the stability of the spring during cutting, some technologies have proposed related clamping structures to assist in the cutting of the spring. For example, there is a utility model patent with a publication number of CN219378817U, which proposes a fixing component for spring cutting processing, a clamping arm arranged on a slide seat, when the two clamping arms are close to each other, the spring to be processed can be clamped and fixed, and the slide seat can slide on the clamping seat and adjust the position, which can be suitable for fixing springs to be processed of different diameters, and can ensure accurate cutting. At the same time, the rotating handle provided can also rotate the screw rod. When the screw rod rotates, it can cooperate with the slider thread to push the slider to slide in the slide groove, thereby adjusting the position of the slide seat.

[0004] From the above disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is conducive to the fixation of the spring during cutting. However, according to the description in the above disclosed technical contents, the clamping arms for clamping the left and right ends of the spring are installed on the side panels, and the left and right side panels are fixedly installed on the workbench. At this time, the distance between the left and right side panels cannot be adjusted. When the spring length is too long, it is inconvenient to place the spring between the left and right side panels with a fixed distance. When the spring length is too short, it is inconvenient for the clamping arm to clamp the spring, which reduces the utilization rate of the fixing component for fixing the spring.

At the same time, when the lower ruler bar 603 moves, it drives the fixed rod 17 on the left side to move in the direction of the spring through the connection with the vertical rod 5, until the clamps 1 on the left and right sides are moved. The drive motor 15 is powered on and the rotating rod 14 is driven to rotate. The rotating rod 14 drives the ball screws 302 on the front and rear sides to rotate at the same time. Since the outer walls of the ball screws 302 on the front and rear sides are provided with threads in opposite directions, and the ball screws 302 and the ball nuts 301 are threadedly connected, the ball screws 302 on the front and rear sides rotate in a circular motion and drive the ball nuts 301 on the front and rear sides to move toward the direction of the spring at the same time, until the clamps 1 on the front and rear sides are in contact with the spring. Finally, the power of the electric push rod 2 is turned on, and the telescopic movement of the internal output shaft of the electric push rod 2 is utilized to enable the clamp 1 to clamp the outer wall of the electric push rod 2.
