Description

Technical Field

[0001] The utility model relates to the technical field of flow drill screw tightening devices, in particular to a flow drill screw tightening device. Background Art

[0002] Flow drill screws can complete the connection operation of dissimilar materials on a single side. After connecting multiple parts, the holes formed on site can maintain sealing. The hot melt self-tapping process eliminates the need to pre-drill holes, pre-set nuts or threads on the parts, simplifies the manufacturing process and reduces costs. Based on the above advantages, flow drill screws and hot melt self-tapping processes are widely used in products such as steel-aluminum hybrid bodies and battery pack trays.

[0003] Before tightening the flow drill screws, the existing flow drill screw tightening device needs to be equipped with a special feeding mechanism to transport the flow drill screws, but the feeding mechanism occupies a large space. In some smaller production environments, the installation of the feeding mechanism is rather cumbersome, which not only delays the production process but may also require manual loading, which increases the labor intensity of the staff. Therefore, we propose a flow drill screw tightening device. Utility Model Content

Before the existing flow drill screw tightening device is used to tighten the flow drill screw, it is necessary to be equipped with a special feeding mechanism to transport the flow drill screw. However, the feeding mechanism occupies a large space. In some smaller production environments, the installation of the feeding mechanism is rather cumbersome, which not only delays the production process but also may require manual loading, which increases the labor intensity of the staff.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flow drill screw tightening device comprises a mounting base plate, a placement box is installed at the top of the mounting base plate near the back side, an electric slide rail is symmetrically arranged at the bottom end of the mounting base plate, an electric slider is arranged inside the electric slide rail, a gantry is fixed to the top of the electric slider, a protective cover is fixed to the bottom of the gantry, a mounting groove is provided inside the protective cover, an electric cylinder is installed on the inner side wall of the mounting groove, a driving motor is fixed to the output end of the electric cylinder, a tightening seat is fixed to the output end of the driving motor, an electromagnet is sleeved on the outer side wall of the tightening seat, and a guide groove is provided on the inner side wall of the mounting groove corresponding to the electromagnet.

[0007] As a preferred solution of the utility model, the placement box is made of rubber material, and the protective cover is made of stainless steel material.

[0008] The technical effect of adopting the above further solution is: the placement box made of rubber material can place the flow drill screws and protect the flow drill screws, while the protective cover made of stainless steel material is not easily affected by external factors and has a long service life.

[0009] As a preferred solution of the utility model, the electric slider is slidably connected to the electric slide rail, so that the electric slider can drive the gantry to move while sliding inside the electric slide rail.

[0010] The technical effect of adopting the above further solution is: through the sliding connection between the electric slider and the electric slide rail, the protective cover can be moved more conveniently when it needs to be moved.

[0011] As a preferred solution of the utility model, the mounting groove is adapted to the electric cylinder, the mounting groove is adapted to the driving motor, and the mounting groove is adapted to the tightening seat.

[0012] The technical effect of adopting the above further solution is: by adapting the mounting groove to the electric cylinder, the mounting groove to the drive motor and the mounting groove to the tightening seat, it is more convenient to install the electric cylinder, the drive motor and the tightening seat.

[0013] As a preferred solution of the utility model, the guide groove is matched with the tightening seat, and a resin layer is bonded to the outer side wall of the guide groove.

[0014] The technical effect of adopting the above further solution is that the design of the resin layer makes it easier for the flow drill screw to pass through the guide groove.

[0015] As a preferred solution of the utility model, a tightening groove is provided at the bottom of the tightening seat, and the tightening groove is adapted to the external flow drill screw.

[0016] The technical effect of adopting the above further solution is that the flow drill screw can be better fixed by the tightening groove, so that the flow drill screw can be better tightened when the driving motor drives the tightening seat to rotate.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, through the design of the placement box, electric slide rail, guide groove and electromagnet, when the convection drill screws need to be loaded, the staff can turn on the electric slide rail, and the electric slider can drive the gantry to move toward the placement box. When the protective cover reaches the top of the placement box, the electric cylinder turns on, driving the tightening seat to descend, and the electromagnet turns on and adsorbs the convection drill screws through the tightening seat. The convection drill screws will be aligned and stuck in the tightening groove under the action of the guide groove, thereby completing the loading of the convection drill screws. It is more convenient, occupies less space, and can be put into the production process faster. BRIEF DESCRIPTION OF THE DRAWINGS
