Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing strip production, and more specifically, to a hole-opening device for a buckle machine of an automobile sealing strip. Background Art

[0002] During the production process of automobile sealing strips, a buckle machine is required to install buckles on the automobile sealing strips. The installation process of the buckle machine includes: using a drill bit to open a hole, and then using a buckle installation device to install a buckle at the hole-opening position.

[0003] Automobile sealing strips are mainly composed of rubber. When directly using a drill bit to open a hole in an automobile sealing strip, the drill bit will first press the upper surface of the automobile sealing strip. Since the stress point of the automobile sealing strip is relatively concentrated at this time, it will cause the automobile sealing strip to easily undergo unstable deformation, and then lead to uneven holes opened on the automobile sealing strip.

[0004] Therefore, those skilled in the art have proposed a hole-opening device for a buckle machine of an automobile sealing strip. Aiming at the problem that the automobile sealing strip is prone to unstable deformation during hole opening, resulting in poor hole-opening effect of the drill bit; a hole-opening device for a buckle machine of an automobile sealing strip is designed, which presses the automobile sealing strip tightly and then uses a drill bit to open a hole in the automobile sealing strip. Content of the Utility Model

[0005] When using a carrier to fix an automobile sealing strip for spraying operation in the prior art, the surface of the automobile sealing strip will be contaminated with organosilicon paint. If a large amount of this organosilicon paint accumulates and solidifies on the surface of the carrier, it will greatly affect the normal use of the carrier.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A hole-opening device for a buckle machine of an automobile sealing strip, which includes a workbench and a drill bit for opening a hole in the automobile sealing strip. An installation seat is arranged on the workbench, and a pressing plate for pressing the upper end surface of the automobile sealing strip is arranged on the installation seat. A hole for the drill bit to pass through is arranged on the pressing plate. By pressing the automobile sealing strip tightly with the pressing plate, its shape is kept stable, and then a drill bit is used to open a hole in the automobile sealing strip; the problem of hole-opening misalignment caused by deformation of the automobile sealing strip during hole opening is avoided. Among them, the drill bit punching position is set at the hole in the middle of the pressing plate, and the automobile sealing strips around the hole are all pressed tightly, and the deformable range of the automobile sealing strip at the hole is relatively small, which is beneficial for the drill bit to accurately drill a hole.

[0008] Preferably, baffles are further arranged on the workbench on both sides of the pressing plate, and the baffles are used for shaping the side surface of the automobile sealing strip. The baffles can shape the side surface of the automobile sealing strip and can cooperate with the pressing plate to better fix the shape of the automobile sealing strip.

[0009] Preferably, the mounting seat includes a mounting bracket fixed to the mounting frame. On the side of the mounting frame far from the ground, a horizontal plate extends towards the automotive sealing strip. A hydraulic rod connected to the pressing plate and used to drive the pressing plate to move up and down is provided on the horizontal plate. By driving the pressing plate to move up and down through the hydraulic rod, the shaping of the automotive sealing strip is realized.

[0010] Preferably, opening grooves are provided on both sides of the pressing plate far from the automotive sealing strip. The baffle is arranged in the opening grooves and can move up and down in the opening grooves. The baffle is also provided with a first limiting end above the opening grooves and a second limiting end below the opening grooves. Among them, setting the baffle in the opening grooves of the pressing plate realizes the synchronous movement of the baffle and the pressing plate, enabling them to simultaneously extrude and shape the automotive sealing strip at a specified position.

[0011] Preferably, a mounting groove is provided on the pressing plate between the two opening grooves. An adjusting plate is fixed in the mounting groove. The bottom surface of the adjusting plate is flush with the bottom surface of the pressing plate. The holes are provided on the adjusting plate. Adjusting plates with various different hole sizes can be set, and the size of the holes can be adjusted by replacing the adjusting plate, so that while meeting the drilling requirements, the holes are as close as possible to the size of the drill bit, reducing the deformation of the automotive sealing strip at the holes during drilling.

[0012] Preferably, one end of the adjusting plate far from the ground extends outwards to form an extension end, and the extension end is fixed to the pressing plate with a nut.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The automotive sealing strip is pressed tightly by the pressing plate to keep its shape stable, and then a drill bit is used to drill holes in the automotive sealing strip; this avoids the misalignment of the holes caused by the deformation of the automotive sealing strip during the hole drilling process. Among them, the drill bit drilling position is set at the hole in the middle of the pressing plate, and the automotive sealing strip around the hole is pressed tightly, and the deformable range of the automotive sealing strip at the hole is small, which is beneficial for the drill bit to accurately drill holes.

[0015] 2. In actual production, adjusting plates with different hole sizes can be selected according to actual needs, so that while meeting the drilling requirements, the holes are as close as possible to the size of the drill bit, reducing the deformation of the automotive sealing strip at the holes during drilling.
