Description

Technical Field

[0001] This utility model relates to the field of door hinge pilot hole processing technology, specifically a door hinge pilot hole processing positioning device. Background Technology

[0002] Door hinge pilot holes are guide holes pre-drilled on the door panel and side panels during the installation of door hinges. Their function is to provide precise positioning for the subsequent installation of hinge cups and hinge seats, ensuring that the hinges are installed securely and the door panel opens and closes smoothly. They are usually located near the edge of the door panel, with the specific distance depending on the type of hinge and the size of the door panel. They provide guidance and positioning for the installation of the hinge cups, ensuring that the hinge cups can be accurately embedded in the door panel.

[0003] A positioning device is needed during the machining of door hinge pilot holes to ensure the pilot holes are accurately positioned on the side of the door panel. Utility model patent CN216503563U discloses a positioning device for machining door hinge pilot holes, comprising a body and an end cap. The body has a profile hole, a positioning hole, and a guide hole. The cross-sectional shape of the profile hole matches the cross-sectional shape of the profile, allowing the profile to pass through it. The axes of the positioning hole and the guide hole are perpendicular to the extension direction of the profile hole. The cross-sectional shape and dimensions of the positioning hole match the door hinge hole on the profile, and the diameter of the guide hole is the same as the diameter of the pilot hole to be machined on the profile. The end cap can pass through the positioning hole and be inserted into the door hinge hole. When using this hinge-mounted hole machining and positioning device to machine the pilot hole of the profile, the profile is inserted into the profile hole, and the end cap is inserted into the hinge hole through the positioning hole. At this time, the axis of the guide hole is collinear with the axis of the pilot hole to be machined. A drilling tool is used to drill the pilot hole on the profile through the guide hole, thereby ensuring the drilling accuracy of the pilot hole to be machined and eliminating machining errors.

[0004] However, common machining positioning devices require moving the door panel below the drilling machine during machining. Since the door panel is heavy, moving and positioning it is difficult. Therefore, a door hinge pilot hole machining positioning device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a door hinge lead hole processing and positioning device, which has advantages such as facilitating the movement and positioning of door panels and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A door hinge pre-hole machining and positioning device includes a machining platform. Two mounting plates are fixedly installed on the top of the machining platform. A mounting top plate is fixedly installed on the top of the mounting plates. A mounting frame is fixedly installed on the top of the mounting top plate. A displacement slider is slidably installed on the inner side wall of the mounting frame. A machining cylinder is fixedly installed at the bottom of the displacement slider. A drilling machine is fixedly installed at the movable end of the machining cylinder. A quick positioning component is provided on the top of the machining platform.

[0008] The rapid positioning component includes a positioning baffle fixedly installed on the top of the processing platform. The top of the processing platform has an installation groove, and a rotating shaft is rotatably installed on the inner side wall of the installation groove. A support roller is fixedly installed on the surface of the rotating shaft.

[0009] Furthermore, a reinforcing rib is fixedly installed on one side of the positioning baffle, and the bottom of the reinforcing rib is fixedly installed on the top of the processing platform.

[0010] Furthermore, the top of the processing platform is slidably mounted on two mounting frames, which are symmetrical to each other.

[0011] Furthermore, a side shaft is rotatably mounted between the inner bottom wall and the inner top wall of the mounting frame, and a side roller is fixedly mounted on the surface of the side shaft.

[0012] Furthermore, side support cylinders are fixedly installed on the opposite sides of the two mounting plates, with the movable end of the side support cylinders fixedly connected to one side of the mounting frame.

[0013] Furthermore, two mounting guide rods are fixedly installed on the inner sidewall of the mounting frame, and a displacement slider is slidably installed on the surface of the mounting guide rods.

[0014] Furthermore, a movable screw is rotatably mounted on the inner wall of the mounting frame, and the movable screw is threadedly connected to the displacement slider. A servo motor is fixedly mounted on one side of the mounting frame, and the output shaft of the servo motor is fixedly connected to one end of the movable screw.

[0015] Furthermore, the top of the mounting plate is provided with a through hole adapted to the machining cylinder, and a controller is fixedly installed on one side of the mounting plate.

[0016] Compared with the prior art, the present invention provides a door hinge pilot hole machining and positioning device, which has the following beneficial effects:

[0017] 1. This door hinge hole machining and positioning device has an installation groove on the top of the machining platform, a rotating shaft on the inner wall of the installation groove, and a support roller on the surface of the rotating shaft. When the door panel is installed on the top of the machining platform, the door panel contacts the support roller, reducing the friction of the door panel movement and making the door panel movement and positioning easier. This solves the problem of common machining and positioning devices where the door panel needs to be moved under the drilling machine during machining, but the door panel is heavy and the movement and positioning are difficult.

[0018] 2. The door hinge guide hole processing and positioning device uses a side support cylinder on one side of the mounting plate. The side support cylinder drives the mounting frame to move, so that the side roller clamps the door panel inside and supports the door panel to prevent the door panel from shifting when processing the door hinge guide hole. At the same time, the side roller contacts the door panel to facilitate the movement of the door panel. Attached Figure Description

[0028] Specifically, the door panel is placed on top of the support roller 11, and the door panel is pushed to move so that one side of the door panel contacts the positioning baffle 8, thereby completing the positioning of one side of the door panel. The displacement slider 5 moves, causing the drilling machine 7 to move to the position where the hole needs to be opened. The processing cylinder 6 drives the drilling machine 7 to move, and a door hinge pilot hole is opened on the top of the door panel.

[0029] Please see Figure 2 and Figure 3 In this embodiment, the top of the door panel processing platform 1 is slidably mounted on two mounting brackets 13, and the two mounting brackets 13 are symmetrical to each other.
