Description

Technical Field

[0001] The utility model relates to the field of industrial manufacturing, and more specifically, to a clamping spring installation device. Background Art

[0002] In the automobile and machinery manufacturing industries, brake calipers are important components of the brake system, and the stability and reliability of their performance are directly related to the safety performance of the vehicle. During the assembly process of brake calipers, the installation of retaining springs is a key link. Retaining springs, as a fastener, are widely used in brake calipers, mainly to fix the piston to prevent axial displacement during operation, thereby ensuring the stability and durability of the brake system.

[0003] The traditional method of installing retaining springs often relies on manual operation, which has many disadvantages. First, manual installation of retaining springs is inefficient and difficult to meet the needs of large-scale production. Second, the manual installation process is prone to problems such as inaccurate installation position and uneven installation force, which leads to loose installation of retaining springs and affects the performance of the brake caliper. In addition, manual operation also has certain safety risks, such as retaining springs popping out and injuring people during installation.

[0004] In order to overcome the limitations of manual installation, a variety of retaining ring installation equipment has appeared on the market; however, when installing retaining rings, the existing equipment generally fixes the pliers body on the tooling first, and then uses a cylinder to directly push the retaining ring for assembly; although this method is simple and direct, if the position on the pliers body corresponding to the retaining ring installation is not fully supported and fixed, then under the strong force of the cylinder, the pliers body may move unnecessarily or even overturn; this situation will not only affect the installation accuracy and stability of the retaining ring and reduce product quality, but may also cause damage to the equipment itself and even threaten the safety of the operator.
