TECHNICAL FIELD

[0001] The utility model relates to a rotary linkage riveting and pressing device for screw sleeve assembly assembling. BACKGROUND

[0002] In the parking brake, the brake small assembly is crucial. When the driver stops the vehicle and pulls up the hand brake, the brake small assembly plays a role, pushes the piston to make the brake pad closely contact with the brake disc, and guarantees the stable parking of the vehicle. The core components include spring seat cover, spring, steel ball cover, etc., and the accurate cooperation of each part is the key to ensure the braking effect.

[0003] The utility model discloses a structure of a brake caliper assembly, and the screw sleeve assembly mentioned in the application is part of the brake caliper assembly and is installed on the parking caliper main body. One end is connected with a rotating support through a steel ball cover screw, and the other end is connected with an adjusting sleeve through a threaded guide rod. When operating, the rotating support drives the steel ball cover screw, and the brake pad is driven to brake through precise transmission. From the attached drawing 1 of the patent specification, the structure and installation position of the brake small assembly can be clearly seen.

[0004] In the production process of the brake small assembly, after each component is completed, it needs to go through an assembly process to form a complete assembly. During assembly, the threaded guide rod is first pressed and assembled. Due to the upward movement trend of the spring, a riveting edge is arranged on the outer periphery of the positioning seat, and the riveting edge is pushed to limit the spring seat cover through riveting and pressing action.

[0005] Therefore, the riveting edge work needs to be performed by a riveting and pressing tool. Since the outer periphery of the positioning seat is usually provided with multiple groups of rivets, the riveting edge work usually needs multiple groups of rivets to simultaneously drive the spring seat cover through a driving member. However, it is difficult to achieve synchronous driving of multiple groups of rivets and the driving member. UTILITY MODEL CONTENTS

[0007] In order to achieve the above object, the utility model provides the following technical scheme: Screw rod screw assembly assembly is with rotary linkage riveting pressure device, including frame, the fixture for clamping product is distributed in the middle part of frame, its characterized in that: frame is installed rotatable rotating part, rotary drive mechanism of control rotating part rotation, third through -hole is penetrated in the middle part of rotating part, the fixture is distributed in the middle part of third through -hole, a plurality of groups of riveting blocks are arranged between rotating part and fixture, a plurality of groups of riveting blocks are sequentially spaced and arranged along the circumference of fixture, the end portion of riveting block away from the fixture is linked with guide column, the frame corresponds to each group of guide column and is equipped with a group of strip -shaped guide hole that is clearance fit with guide column, the guide column is arranged along the radial of rotating part, the rotating part corresponds to each group of guide column and is equipped with a group of inclined sliding slot.

[0008] Adopt the above technical scheme, when rotary drive mechanism drives rotating part rotation, inclined sliding slot rotates along with it. The inclined structure of inclined sliding slot converts the rotating movement of rotating part into the thrust of guide column, so that the guide column moves in the strip-shaped guide hole and approaches the fixture, so that the riveting block pushes the riveting edge, and the riveting edge work is completed. As can be known, the present scheme ensures that a plurality of groups of riveting blocks can be driven synchronously, solves the problem that a plurality of groups of riveting blocks and driving pieces are difficult to realize synchronous driving, and reduces the cost of riveting pressure device.

[0012] Using the above technical solution, when the piston rod of the third cylinder extends or retracts, the positioning block is connected to the screw holes on the rotating ring via screws, and the push rod drives the rotating ring to rotate through the positioning block. The rotating ring is fixedly connected to the ring plate, so the ring plate rotates together with the rotating ring. The ring plate is provided with an inclined sliding groove. When the ring plate rotates, the inclined structure of the inclined sliding groove pushes the guide post to move along the strip-shaped guide hole and move closer to the clamp, thereby pushing the riveting block to perform riveting work.

[0030] The rotary driving mechanism comprises a third cylinder a8, a pushing rod a9 hinged to the output end of the third cylinder a8, a hinge block a9 hinged to the body of the third cylinder a8, the hinge block a9 being fixed on a mounting seat a10, the mounting seat a10 being distributed on the side of the rotating ring a2 and fixed on the rack, and the positioning block a3 being linked with the pushing rod a9. The mounting seat a10 is fixed on the rack, so as to facilitate the installation of the third cylinder a8. The hinge block a9 is arranged, so that the third cylinder a8 as a whole can swing and adapt to the rotating movement of the rotating member when the output rod of the third cylinder a8 performs the telescopic movement, thereby avoiding interference.

[0031] The clamp a1 is distributed in the middle of the third through hole a5, and three groups of riveting blocks a11 are arranged between the rotating ring a2 and the clamp a1.

The inclined structure of the inclined sliding groove a4 converts the rotary motion of the rotating ring a2 into a pushing force on the guide column a12, so that the guide column a12 moves in the strip-shaped guide hole a18 and approaches the clamp a1, so that the riveting block a11 pushes the riveting edge, and the riveting edge work is completed.
