Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a grinding mechanism and grinding device for the bottom surface of a longitudinal beam. Background Technology

[0002] In existing automotive longitudinal beam grinding processes, the bottom surface of the longitudinal beam is mostly ground manually. This method is not only time-consuming and labor-intensive, but also inefficient.

[0003] To address the aforementioned issues, Chinese patent document "A Rear Longitudinal Beam Grinding Assembly" (patent application number: 202420199804.8) discloses a rear longitudinal beam grinding assembly, which achieves automatic grinding of longitudinal beam workpieces. However, this solution has the following drawbacks:

[0004] 1. In this solution, the longitudinal beams can only be ground one by one, which is not only inefficient, but also unsuitable for production lines.

[0005] 2. This solution requires manual operation and adjustment of the longitudinal beam and grinding components multiple times, and cannot achieve fully automated grinding. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a grinding mechanism and grinding device for the bottom surface of longitudinal beams, which realizes fully automatic grinding of the bottom surface of longitudinal beams and is suitable for production lines.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a grinding mechanism for the bottom surface of a longitudinal beam, including a transverse sliding plate, a transverse motor, a lifting plate, a rotating shaft, and a grinding motor; the transverse motor is used to drive the transverse sliding plate to move horizontally; a first lifting cylinder is provided on the transverse sliding plate, and the piston rod of the first lifting cylinder is connected to the lifting plate to drive the lifting plate to move up and down; the rotating shaft is mounted on the lifting plate through a support, and a driven wheel and at least one grinding wheel are provided on the rotating shaft, the grinding wheel being located below the corresponding longitudinal beam workpiece; the grinding motor is mounted on the lifting plate, and the drive shaft of the grinding motor is connected to a driving wheel, the driving wheel being connected to the driven wheel through a belt, thereby driving the grinding wheel to rotate.

[0008] A further improvement is that the drive shaft of the transverse motor is connected to a gear, and the bottom of the transverse slide plate is provided with a rack that meshes with the gear.

[0009] A further improvement is that the transverse sliding plate is equipped with a buffer adapted to the lifting plate.

[0010] A further improvement is that two grinding wheels are provided, located at both ends of the rotating shaft, which can grind the bottom surfaces of the two longitudinal beam workpieces simultaneously.

[0011] This utility model also provides a grinding device, including a frame on which at least one grinding mechanism for the bottom surface of the longitudinal beam as described above is provided.

[0012] A further improvement is that the transverse motor is mounted on the frame, and the frame is equipped with a linear guide rail adapted to the transverse slide.

[0013] Further improvements include a floating friction roller mechanism for pressing the longitudinal beam workpiece and driving it to translate.

[0014] A further improvement is that the floating friction roller mechanism includes a gantry frame spanning the machine frame. Several second lifting cylinders are provided on the crossbeam of the gantry frame. The piston rod of each second lifting cylinder is connected downward to a friction motor. The drive shaft of the friction motor is connected to a friction wheel. The friction wheel is used to press against the top surface of the corresponding longitudinal beam workpiece, thereby driving the longitudinal beam workpiece to move horizontally.

[0015] A further improvement is that four second lifting cylinders are provided, evenly distributed on the crossbeam of the gantry frame.

[0016] A further improvement is that adjustable feet are provided at the bottom of both the gantry frame and the machine frame.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, after the longitudinal beam workpiece enters, it is pressed by a floating friction pressure roller. The friction motor drives the friction roller to rotate, and the workpiece moves forward by friction. In conjunction with multiple longitudinal beam bottom surface grinding mechanisms, multiple longitudinal beam workpieces can be ground at the same time, which not only improves work efficiency, but is also suitable for production lines.

[0019] 2. In this utility model, the first lifting cylinder drives the grinding wheel to move up and down, which can perform floating grinding on the longitudinal beam workpiece.

[0020] 3. In this utility model, the transverse motor drives the gear rack to move the entire grinding component laterally, which can satisfy the requirement of covering and grinding the bottom surface of the longitudinal beam workpiece.

[0021] 4. In this utility model, the second lifting cylinder drives the friction motor to move up and down, and the position of the cylinder detection switch is adjusted so that the second lifting cylinder can reach different strokes to adapt to product workpieces of different thicknesses.
