Description

TECHNICAL FIELD

[0001] The utility model relates to automatic processing equipment technical field, concretely relates to brake small assembly riveting and pressing frock. BACKGROUND

[0002] In the field of parking brake, brake small assembly plays a vital role. When the driver stops the vehicle, the brake is activated by hand brake, and the brake small assembly begins to play a role. It pushes the piston, and the brake pad is combined with the brake disc to ensure the vehicle to be parked stably. The core components of the brake small assembly include spring seat cover, spring, steel ball cover, steel ball cover screw, threaded guide rod, steel ball and gasket. The accurate cooperation between each component is the key to ensure the braking effect.

[0003] Chinese utility model patent publication number "CN205025976U" discloses a brake caliper assembly design, and the brake small assembly mentioned in the present application is part of the brake caliper assembly, which is responsible for installation on the parking caliper main body. One end is connected with the rotating support through the steel ball cover screw, and the other end is connected with the adjusting screw through the threaded guide rod. In the operation process, the movement of the rotating support will drive the steel ball cover screw, and after a series of precise transmission, the brake pad on the brake caliper is driven to realize the braking function. In the specification attached to the patent publication Figure 1 The specific structure of the brake small assembly and its installation position can be clearly seen.

[0005] However, in the production process of the brake small assembly, after each component is processed, it needs to go through the assembly process to form a complete assembly. When the threaded guide rod is pressed and assembled, due to the action of the spring, the threaded guide rod will have a tendency to move upward. At this time, simply relying on the above pressing device, there is no limiting part below to limit the threaded guide rod. After the cylinder is withdrawn, the threaded guide rod pops up. The existing brake small assembly is connected with the positioning seat cover and the spring seat cover to prevent the threaded guide rod from popping up upward. Therefore, after the threaded guide rod is pressed down during the assembly process, the spring seat cover needs to be riveted and fixedly connected with the positioning seat cover. The existing riveting and pressing frock pushes the spring seat cover to rivet the edge by cooperating the rivet block with the driving part. The rivet block and the driving part are axially arranged to push the axial direction, which occupies a large space, greatly increasing the production cost.
