Description

Technical Field

[0001] The utility model relates to the technical field of automobile roof manufacturing, in particular to a roof plastic buckle pressing mechanism. Background Art

[0002] As an important part of the vehicle interior, the car ceiling plays an indispensable role in improving the competitiveness of the car. Its functions are also changing. It not only improves the decoration of the car interior, but also requires the ceiling to have good heat insulation and thermal insulation effects, as well as reduce the noise inside the car and improve the sound absorption effect. At present, after the car ceiling is processed, it is usually necessary to bond multiple plastic parts and metal parts on its back side, mainly to connect and fix the ceiling to the body structure.

[0003] In the plastic buckle pressing tooling structure of the prior art, a limit seat for positioning the automobile roof is usually provided at the lower end of the frame, and a pressing mechanism that can be vertically raised and lowered is provided on the top plate of the frame. Before the pressing action, the corresponding plastic parts or metal parts need to be pre-installed on the lower end surface of the pressing mechanism. Due to the limitations of space and pre-installation direction, the pre-installation efficiency of the plastic parts or metal parts is low, and since it is installed from bottom to top, the field of vision is limited, resulting in deviations in the pre-installation position.

[0004] On the other hand, the pressing tooling in the prior art can generally only correspond to one specification of ceiling pressing, that is, each specification of ceiling pressing requires a dedicated tooling, which not only increases the manufacturing cost, but also causes waste of resources due to too many tools. Utility Model Content

[0005] In order to overcome at least one defect in the above-mentioned prior art, the utility model provides a ceiling plastic buckle pressing mechanism with a simple structure. When used for pressing ceilings of different specifications, only the pressing mold needs to be replaced without remaking the frame, which saves manufacturing costs and is convenient for mold changing.

[0006] The utility model provides a ceiling plastic buckle pressing mechanism, comprising

[0007] A frame, wherein a mounting frame which can be lifted and lowered vertically is arranged on the top plate of the frame;

[0008] A turning frame, one end of which is rotatably connected to the lower end of the mounting frame, and the mounting frame is provided with a driving component for driving the turning frame to turn downward to a part replacement position or to be stored upward to a press-fitting position parallel to the mounting frame;

[0009] An upper mold frame is detachably connected to the lower end surface of the flip frame, and a plurality of clamping components for clamping plastic buckles are arranged on the upper mold frame;

[0010] The lower mold frame is detachably connected to the workbench of the frame, and the upper end of the lower mold frame is provided with a positioning seat for placing and positioning the ceiling, and a plurality of first clamping components arranged on the periphery of the positioning seat and used for flipping and clamping the ceiling.

[0011] Compared with the prior art, the ceiling plastic buckle pressing mechanism of the utility model has the following advantages:

[0012] 1. The press-fitting assembly is divided into a mounting frame and a flip bracket, and the flip bracket and the mounting frame can rotate, that is, in the initial position, the flip bracket is stored under the frame, and the flip bracket is parallel to the mounting frame. This position allows the manipulator to have more room for movement when applying glue at the position where the parts need to be press-fitted on the upper surface of the car roof; when the plastic or metal parts to be press-fitted need to be installed, the driving assembly drives the flip bracket to rotate in a direction away from the mounting frame until the flip bracket and the mounting frame are in a vertical state. This position is the loading position. This angle position can more clearly display the position of the positioning assembly, which is convenient for workers or manipulators to pre-install the plastic or metal parts to be press-fitted on the corresponding positioning assembly on the flip bracket, which can not only improve the pre-installation efficiency of the press-fitted parts, but also ensure the accuracy of the pre-installation position, ensure that the position on the car roof after the press-fitting is completed meets the design requirements, and improve the product qualification rate.

After such improvement, it is only necessary to design the corresponding press-fitting mold according to the ceiling specifications, and the frame part does not need to be repeatedly manufactured, saving manufacturing costs and storage space; and in the above structure, since the flip frame can rotate an angle, it is convenient to replace the upper mold frame.

[0014] As an improvement, the left and right ends of the upper mold frame are both provided with connecting plates, and each of the connecting plates is provided with a connecting hole; the left and right ends of the lower surface of the flip frame are respectively provided with first bolts that match the connecting holes, and each of the first bolts is also sleeved with a first pressing plate for pressing the lower end surface of the connecting plate. In the above improved structure, the bolt connection structure makes the disassembly and assembly of the upper mold frame and the flip frame more convenient, and the connection structure is stable; the additional screw connection structure is also more convenient and quick for the later replacement of upper mold frames of different specifications.

[0015] In a further improvement, two mounting bars extending along the length direction are arranged at both left and right ends of the lower surface of the flip frame, and the two mounting bars at each end are arranged in parallel and spaced apart along the front-rear direction of the flip frame; each mounting bar is provided with a plurality of threaded holes spaced apart along the length direction and used for engaging with the first bolts connecting the upper mold frame. In the above improved structure, the threaded holes at different positions on the mounting bars can be used for mounting and fixing upper mold frames of different specifications, and the structure has strong versatility.

[0016] As a further improvement, each of the installation bars is provided with at least one positioning pin, and the upper mold frame is provided with a plurality of positioning holes for respectively engaging with each of the positioning pins.

[0017] Further improvement, the upper end surface of the workbench is provided with a plurality of installation grooves extending along the front-to-back direction and arranged at intervals along the left-to-right direction, and the front and rear ends of at least two installation grooves symmetrically located on the left and right sides of the lower mold frame are respectively provided with second clamping assemblies, and each second clamping assembly can slide forward and backward in the installation groove; the front and rear ends on the left and right sides of the lower mold frame are both protrudingly provided with press-fitting skirts for pressing and positioning the corresponding second clamping assemblies.
