Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a guide mechanism for centerless grinders. Background Art

[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] First, when the workpiece is to be polished, the staff needs to hold the workpiece and push it between the grinding and guide wheels. However, during the pushing process, it is difficult to ensure the parallelism between the workpiece and the roller. If the tilt is too large, the end of the workpiece is easily damaged.

[0004] In addition, some workpieces are rough and uneven when in contact with the grinding wheel during the grinding process. Once the pressure is too great, they are easily bounced out of the machine, which not only easily damages the machine but also poses a certain risk. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a guide mechanism for a centerless grinder, which overcomes the deficiencies of the prior art and effectively solves the problems that the end of the workpiece is easily damaged during feeding and the workpiece is easily bounced out of the machine due to excessive pressure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A guide mechanism for a centerless grinder, comprising a grinder frame, a guide assembly is arranged on one side of the outer wall of the top of the grinder frame, and the guide assembly comprises a fixed frame welded to the outer wall of the top of the grinder frame, guide pulleys rotatably connected to the inner wall of the grinder frame and distributed at equal distances, guide plates rotatably connected to the inner wall of the fixed frame and distributed symmetrically, and a fastening knob screwed to the outer wall of one end of the fixed frame;

[0008] An anti-slip assembly is provided on the top of the grinding machine frame, and the anti-slip assembly includes a cylinder arranged on the top of the grinding machine frame, an anti-slip frame connected to the cylinder piston rod, symmetrically distributed clamping wheels rotatably connected to the outer walls at both ends of the anti-slip frame, and a torsion spring connected between the clamping wheel and the anti-slip frame.

[0009] Preferably, a grinding wheel is installed at one end of the inner wall at the bottom of the grinder frame, and a guide wheel is installed at the other end of the inner wall at the bottom of the grinder frame.

[0010] Preferably, a water funnel is provided between the grinding wheel and the guide wheel, and a cooling water pipe is connected to an outer wall on one side of the water funnel.

[0011] Preferably, a workpiece support plate is installed on the inner wall of the bottom of the grinding machine frame, and the workpiece support plate is arranged at the bottom between the grinding wheel and the guide wheel.

[0012] Preferably, a drainage groove is provided on the inner wall of the bottom of the grinder frame, and a water tank is installed on the outer wall of the bottom of the grinder frame.
