Description

Technical Field

[0001] This utility model relates to a vehicle headlight pressing device, and in particular to an automatic positioning pressing device for automotive headlights. Background Technology

[0002] During the production process of automotive lights, the lamp housing and lamp cover need to be pressed together by a pressing device to form a complete lamp. With the development of technology, the pressing and installation of the lamp housing and lamp cover has now been basically mechanized. The upper mold base is raised and lowered by a lifting cylinder, and the lower mold base is fixed on the worktable. The upper mold base is pressed down by the lifting cylinder to press the lamp housing and lamp cover together.

[0003] This structure requires extremely high installation precision for the upper and lower mold bases. If it is necessary to press different sizes of car lights, a complex adjustment process is required when changing the mold, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic positioning and pressing device for automotive headlights that has low requirements for mold positioning accuracy and is easy to position.

[0005] The technical solution to achieve the purpose of this utility model is as follows:

[0006] An automatic positioning and pressing device for automotive headlights includes a worktable, a frame fixed on the worktable, a top plate fixed on the upper end of the frame, and a lifting cylinder fixed on the top plate. The lifting cylinder is equipped with a cylinder shaft that can move up and down. A lifting plate is fixed to the lower end of the cylinder shaft. The lifting plate is provided with a guide hole. A guide rod is provided on the lifting plate that passes through the guide hole and slides with the lifting plate. An upper mold base is provided below the lifting plate. The lower end of the guide rod passes through the guide hole and is fixedly connected to the upper mold base. A limit block is provided at the upper end of the guide rod. The lower surface of the limit block abuts against the upper surface of the lifting plate. The upper mold base is provided with an upper mold cavity. Multiple pressing columns are fixed on the lifting plate. The pressing columns extend into the upper mold cavity. An upper abutment slope is provided on the lower end face of the upper mold base.

[0007] The upper surface of the workbench is provided with a support plate, which has multiple ball grooves and mounting holes. Rollable balls are provided in the ball grooves. The support plate is provided with side limiting plates and inner limiting plates. Mounting bolts are provided in the mounting holes. The side limiting plates and inner limiting plates are fixedly connected to the support plate by the mounting bolts. The side limiting plates and inner limiting plates mark a limiting area with notches on the support plate. A lower mold base is provided in the limiting area. The balls support the lower mold base. The lower mold base has a lower mold cavity. A support column is provided in the lower mold cavity. The upper surface of the lower mold base is provided with a lower abutting inclined surface that mates with the upper abutting inclined surface.

[0008] With the above structure, when pressing different specifications of car lights is required, it is only necessary to first install the corresponding upper mold base, and then install the side limiting plate and inner limiting plate at the corresponding positions on the support plate to form a limiting area with a notch. The lower mold base is pushed into the limiting area from the notch, and coarse positioning is formed by the side limiting plate and the inner limiting plate. Then, the cylinder drives the lifting plate to descend, and the upper abutting inclined surface of the upper mold base contacts the lower abutting inclined surface of the lower mold base. The lower mold base moves under the force of the upper abutting inclined surface against the lower abutting inclined surface, and finally moves through the upper abutting inclined surface. The cooperation between the upper and lower abutment inclined surfaces achieves precise positioning of the upper and lower mold bases. Then, the lifting plate continues to descend under the drive of the lifting cylinder, while the upper and lower mold bases remain fixed. The pressing column continues to move downward, applying force to the lampshade and lamp housing to complete the pressing operation. Then, the lifting cylinder drives the lifting plate and the upper mold base to rise, and the operator removes the pressed lamp from the lower mold base. This utility model reduces the positioning requirements of the lower mold base on the support plate and improves the overall pressing efficiency of the lamp by using two positioning methods: coarse positioning and precise positioning.

[0009] Preferably, in order to facilitate the precise positioning of the upper and lower molds, a spring is fitted on the guide rod, with the upper end of the spring abutting against the lifting plate and the lower end abutting against the upper end surface of the upper mold base.

[0010] Preferably, in order to facilitate the installation of the lampshade in the upper mold base, the pressing column is provided with a negative pressure suction hole, and the negative pressure provided by the negative pressure suction hole will adsorb the lampshade onto the lower end face of the pressing column.
