Description

Technical Field

[0001] The utility model relates to the technical field of vehicle production equipment, in particular to a vehicle door frame cutting device. Background Art

[0002] Vehicles are equipment used for handling and transportation. They can be used for moving large and heavy goods over long distances. They have a fast speed and a large load capacity. Common examples include cars, buses, trucks, etc. During the movement of the vehicle, due to the high speed, people or objects in the vehicle need to be protected. The doors need to be made of the same material as the vehicle to prevent goods or people from falling.

[0003] In order to maintain the appearance and aerodynamics of the vehicle, the door frame of the vehicle is of a special shape instead of being square. Therefore, higher precision is required in the production of the door. The offset during disassembly may easily lead to deviation, which may result in the need for further shaping of the door frame at a later stage, thereby increasing the production time of the door and reducing production efficiency. Therefore, a vehicle door frame cutting device is proposed to avoid the offset of the door during cutting. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-2 The utility model is a vehicle door frame cutting device, comprising a cutting base 1, a slide groove 2 is chiseled at one end of the top of the cutting base 1, two slide plates 3 are slidably arranged inside the slide groove 2, a plurality of limit rollers 4 are rotatably connected to the top of the slide plate 3 at equal intervals, a T-shaped support block 11 is movably connected to the end of the cutting base 1 away from the slide groove 2, and an L-shaped cutting block 8 that can move up and down is arranged above the T-shaped support block 11.

[0018] The inner rotation of the slide 2 is connected with a bidirectional screw rod 5, and the two ends of the bidirectional screw rod 5 are respectively threadedly connected with the two slide plates 3. According to the width of the door frame, the bidirectional screw rod 5 is rotated. As the bidirectional screw rod 5 rotates, the two slide plates 3 approach each other. The cutting base 1 is located above one end of the T-shaped support block 11 and is fixedly connected with a stand 6. The top of the stand 6 is fixedly connected with a hydraulic cylinder 7. The output end of the hydraulic cylinder 7 passes through the stand 6 and is fixedly connected to the L-shaped cutting block 8. The bottom of the L-shaped cutting block 8 is away from the end of the T-shaped support block 11. An extrusion plate 9 that can move up and down is provided. A No. 1 spring 10 is fixedly connected between the top of the extrusion plate 9 and the bottom of the L-shaped cutting block 8. The L-shaped cutting block 8 moves downward and is connected to the T After the T-shaped support block 11 contacts, the extrusion plate 9 contacts the cutting base 1, and the door frame is squeezed away from one end of the T-shaped support block 11 by the extrusion plate 9 to limit the door frame. The bottom of the cutting base 1 and the two sides of the T-shaped support block 11 are equidistantly fixedly connected with a plurality of T-shaped support columns 12, the T-shaped support block 11 is plugged into the T-shaped support column 12, and a No. 2 spring 13 is fixedly connected between the bottom of the T-shaped support block 11 and the T-shaped support column 12. The T-shaped support block 11 is pushed downward by the L-shaped cutting block 8 to leave the cutting base 1. When the L-shaped cutting block 8 is reset, the T-shaped support block 11 is reset under the push of the No. 2 spring 13 and returns to the end of the cutting base 1.

[0019] Specifically, when the utility model is used, the bidirectional screw rod 5 is rotated according to the width of the door frame. As the bidirectional screw rod 5 rotates, the two slides 3 approach each other, and the limiting rollers 4 on the top thereof limit the door frame to prevent the door frame from shifting sideways and affecting the cutting accuracy. When the door frame is pushed to the bottom of the L-shaped cutting block 8, the hydraulic cylinder 7 is turned on, and the L-shaped cutting block 8 is pushed downward by the output end of the hydraulic cylinder 7. The L-shaped cutting block 8 and the T-shaped supporting block 11 squeeze the end of the door frame that needs to be cut off, and cooperate with the extrusion plate 9 and the cutting base 1 so that the two ends that need to be cut off are restricted, so as to avoid the displacement of the door frame and affect the accuracy during cutting.
