Description

Technical Field

[0001] The invention relates to the technical field of parts riveting, in particular to a rivet nut riveting device for a support of a car water tank condenser. Background Art

[0002] In the automobile manufacturing process, the fixing and installation of the automobile radiator condenser is a crucial link. In order to ensure that the automobile radiator condenser maintains a stable position during the operation of the automobile and can withstand various forces, a reliable connection method is required to connect the automobile radiator condenser bracket to other structures. As a commonly used connection method, rivet nuts have the advantages of firm connection, high reliability, and easy installation. Therefore, they are widely used in the connection of automobile radiator condenser brackets.

[0003] Traditional riveting devices have certain limitations: Traditional riveting devices often use simple conveyor belts or rollers to transport automobile water tank condenser brackets, which can easily cause the brackets to deviate and shake, affecting the accuracy and quality of riveting. Moreover, during the riveting process, the brackets have no effective limiting measures and are prone to tilting, increasing the difficulty and risk of riveting.

[0004] Traditional riveting devices usually use manual or simple mechanical feeding methods when feeding rivet nuts. This feeding method is inefficient and difficult to meet the needs of large-scale production. In addition, the nut is prone to falling off and inaccurate positioning during the feeding process, which affects the quality and efficiency of riveting.

[0005] The traditional riveting device lacks effective synergy between the various components, and often requires manual coordination and operation, which increases the complexity and difficulty of the operation. Moreover, the asynchronous actions between different components can easily lead to problems in the riveting process, affecting production efficiency and quality.

[0006] In summary, with the development of the automobile manufacturing industry, the requirements for production efficiency are getting higher and higher. The traditional manual riveting method is not only inefficient, but also difficult to ensure quality. Therefore, a riveting device for automobile radiator condenser bracket rivet nuts is needed, which can realize efficient and accurate riveting operations, improve production efficiency and reduce production costs.

[0019] (1) The present invention has a stable conveying and clamping effect: the square steel bracket is placed in the conveying path and supported by the transmission roller, which ensures the stability of the conveying process; at the same time, the operation of the motor 1 causes the screw to rotate, driving the lifting plate to descend, thereby making all the L plates close to the upper surface of the square steel bracket, and the two cross plates are moved close to the front and rear sides of the square steel bracket through the gear cylinder transmission; the L plate contacts the top of the square steel bracket through the roller 1, the cross plate contacts the front and rear sides of the square steel bracket through the roller 2, and the transmission roller contacts and supports the bottom of the square steel bracket, so as to wrap and clamp the square steel bracket;

[0021] (2) The present invention has the functions of automatic feeding and intermittent operation: the feeding mechanism realizes the automatic feeding of the rivet nut through the cooperation of the turntable, the second motor, the rotating shaft and other components. When the front clamping mouth is fed by the external feeding equipment to squeeze the two clamping claw inclined surfaces located in the front, the clamping claw is squeezed open, driving the corresponding arc plate 1 to slide, and the corresponding arc plate 2 to slide under the transmission of the spur gear, so that the two clamping claws at the rear move open, and the rivet nut located above the mounting hole loses its clamping and falls into the mounting hole. The operation of motor 2 moves the turntable, and the front clamp holding a new rivet nut rotates half a circle to above the empty mounting hole, while the clamp and material mouth that have lost the rivet nut rotate half a circle to the front to wait for feeding, thereby realizing cyclic and intermittent continuous operation and improving processing efficiency. In addition, when used in conjunction with the intermittently moved and transported square steel bracket, the mounting hole can be intermittently moved to the bottom of the material mouth and the rivet nut for assembly, and the riveting gun can also rivet the mounting hole with the assembled rivet nut, providing a reliable connection foundation for the subsequent fixation and installation of the automobile radiator condenser in the entire automobile structure.
