Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, in particular to a grinding mechanism for a tubular workpiece. Background Art

[0002] Water storage tanks, pressure tanks, and other components typically utilize a tubular structure, with a hollow cylinder at the center. This cylindrical structure is typically formed by bending a flat sheet of metal into a tubular shape and then welding along the tube's axis to secure the shape. Side panels (also known as end caps) are welded to each end of the cylinder to seal the tank.

[0003] This structural design and processing method results in two types of welds on the outer surface of the workpiece: one is the axial weld located at the middle cylinder; the other is the annular weld at the connection between the side plate and the middle cylinder. In order to improve the surface quality of the workpiece, these welds need to be polished.

[0004] The outer surface of a workpiece with such a structure often has an axial weld at the central cylinder and a circular weld at the connection between the side plate and the central part. In order to improve the surface quality, the welds need to be polished.

[0005] However, due to the presence of two welds of different shapes (or directions), the workpiece must be reoriented or clamped again during the grinding process to accommodate the grinding requirements of the different welds, which undoubtedly reduces processing efficiency. Utility Model Content

[0006] The purpose of the present invention is to solve the above problems and provide a grinding mechanism for tubular workpieces, which can improve the processing efficiency.

[0007] To achieve the above objectives, the technical solution adopted by the utility model is a grinding mechanism for tubular workpieces, which includes a base mounting plate, a base is provided at the upper end of the base mounting plate, a motor mounting bracket is rotatably provided on the base, the angle of the motor mounting bracket is fixed by a locking device, a motor is provided on the motor mounting bracket, a grinding mounting plate is provided on the motor mounting bracket, and a grinding unit driven by a motor is provided on the grinding mounting plate.

[0008] Furthermore, in order to adapt to tanks of different diameters and the problem that the distance between the weld and the grinding unit is different due to the change in diameter of different areas of the tank, and the weld cannot be ground, a guide rail is provided on the base mounting plate, and the base slides on the guide rail under the drive of the transverse drive mechanism, so that the grinding unit can fit with the tank body, thereby ensuring the grinding quality.

[0009] Furthermore, the base is connected to the motor mounting bracket via a rotating shaft, an arc-shaped hole is provided on the motor mounting bracket, and the locking device is a locking bolt through which a screw passes through the arc-shaped hole and is threadedly connected to the base, so that the grinding unit can rotate around the rotating shaft so that the grinding unit can grind the axial weld and the annular weld on the tank body. When grinding the two types of welds, there is no need to clamp the workpiece for the second time, thereby improving the processing efficiency.

[0010] Furthermore, the grinding unit includes a driving wheel and a grinding wheel that are arranged at intervals. The driving wheel is connected to the motor, and the sanding belt is wound around the driving wheel and the grinding wheel. The sanding belt is a conventional grinding tool, which can facilitate the procurement of parts.

[0011] Furthermore, limit wheels are provided on both sides of the driving wheel to prevent the sanding belt from falling off the grinding wheel.

[0012] Furthermore, the outer side of the limiting wheel is covered with a buffer layer, which can provide buffering when the grinding unit moves toward the workpiece to protect the motor and the like.

[0013] Furthermore, a push frame is provided on the polishing mounting plate, and a gripping portion is provided on the push frame to facilitate manual debugging by staff.

[0014] Furthermore, a dust suction pipe is provided on the working side of the grinding unit, and the dust suction pipe is connected to a dust suction device to collect dust generated during the grinding process, thereby improving the working environment and protecting the health of workers.

[0015] The beneficial effects of the utility model are as follows: the motor mounting frame can swing, thereby adjusting the angle of the grinding unit according to the weld to be ground, so that the grinding unit can grind the axial weld and the annular weld on the tank body. During the grinding process, there is no need to clamp the workpiece for the second time, thereby improving the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The base 2 slides on the guide rail 6 under the drive of a horizontal drive mechanism 7. The horizontal drive mechanism 7 can be a cylinder, an electric push rod, etc. The upper end of the base mounting plate 1 is provided with a base 2, on which a motor mounting frame 3 is rotatably arranged.

The motor mounting frame 3 is provided with an arc hole 9. The center of the arc hole 9 is coincident with the center of the rotating shaft 8. The locking device is a locking bolt 10 that is a screw rod passing through the arc hole 9 and is threadedly connected to the base 2. When the locking bolt 10 is loosened, the motor mounting frame 3 can be rotated. After the rotation is completed, the locking bolt 10 is tightened.

[0025] The motor mounting frame 3 is provided with a motor 4, and a grinding mounting plate 5 is fixedly provided on the motor mounting frame 3. A grinding unit driven by the motor 4 is provided on the grinding mounting plate 5. The grinding unit can be a grinding wheel, etc. In this embodiment, the grinding unit includes a drive wheel 12 and a grinding wheel 13 arranged at intervals. The drive wheel 12 is in transmission connection with the motor 4. The sanding belt 11 is wound around the drive wheel 12 and the grinding wheel 13. To tension the sanding belt, a tensioning wheel is also provided on the sanding mounting plate 5. The tensioning wheel contacts the inner side of the sanding belt 11. The movement path of the sanding belt 11 is in the same direction as the axis of the rotating shaft 8 and the length direction of the guide rail 6. Limiting wheels 14 are provided on both sides of the drive wheel 12. The limiting wheels 14 are arranged in the same direction as the grinding wheel 13. The limiting wheels 14 are rotatably provided on the limiting frame, and the limiting frame is fixedly provided on the sanding mounting plate 5. The outer side of the limiting wheel 14 is covered with a buffer layer, which can be made of elastic materials such as rubber and silicone. The outer wall of the buffer layer is higher than the outer surface of the sanding belt 11.

[0026] A pushing frame 15 is provided on the grinding mounting plate 5, and the pushing frame 15 passes under the sanding belt 11.

[0027] Specific working process: The base mounting plate 1 can be as follows Figure 6 As shown, it is mounted on a lifting unit, which moves in a vertical direction driven by a motor, a screw, etc. After the workpiece is installed, the height of the base mounting plate 1 is adjusted so that the abrasive belt 11 on the grinding wheel 13 is at the same height as the weld. The transverse drive mechanism 7 then drives the base 2 toward the workpiece so that the abrasive belt 11 on the outside of the grinding wheel 13 contacts the weld. As the motor 4 operates, the abrasive belt 11 moves to grind the weld. When the axis of the grinding wheel 13 is parallel to the horizontal line, the circumferential weld can be ground as the workpiece rotates. When the axis of the grinding wheel 13 is in a vertical state, the axial weld can be ground as the workpiece moves or the base mounting plate 1 moves laterally.
