Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a sand-repairing device with a wall-mounted grinding wheel bracket. Background Technology

[0002] In mold processing, parts such as mold bases and templates need to be drilled. During the processing, twist drills will wear out and need to be reground before they can be used again.

[0003] Currently, a large number of mold parts require drilling. During the machining process, drill bits wear down and need to be re-grinded before reuse. Grinding wheels, however, can experience unevenness and vibration during use. The existing process involves using commercially available handheld grinding wheel dressers to dress the grinding wheel. After dressing, the wheel is roughly flat but still has slight waviness, and it cannot dress the sides or ensure a 90° angle between the sides and the circumference. This results in suboptimal performance when dressing drill bits. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0010] A further feature of this invention is that the base includes a workbench, the grinding wheel is fixed above the workbench, and tripods fixed to the wall are provided on both sides below the workbench, with a reinforcing rod between the two tripods.

[0011] By adopting the above technical solution, the wall-mounted structure can be cleaned without any blind spots, making it easier to clean.

[0012] A further feature of this invention is that the trimming track has a wedge-shaped groove in the middle that cooperates with the moving block, and the moving block has a first locking rod for fixing the moving block. The first locking rod achieves a locking effect by penetrating the threaded hole of the moving block and contacting the trimming track.

[0013] A further feature of this invention is that a second locking rod is provided at the connection between the moving block and the connecting rod, and the second locking rod is used to adjust the fixing angle of the connecting rod.

[0016] By adopting the above technical solution, the trimming head can be adjusted, the trimming range and angle are wider, and it is easier to maintain and repair.

[0017] In summary, this utility model has the following beneficial effects: the wall-mounted bracket saves floor space, reduces the vibration of the grinding wheel, and reduces dead corners for cleaning the floor; compared with the traditional handheld grinding wheel dresser, this dressing device is safer and more reliable. Through dressing, it can improve the problem of grinding wheel imbalance and vibration. After dressing, the surface of the grinding wheel is flat and wave-free, and the side and circumference are at 90 degrees, so that the grinding wheel is kept in the best working condition.
