Description

Two-sided grinding device simultaneously of sword tooth on saw bit

Technical Field

The utility model relates to a technical field that the both ends face of sword tooth was polished on the saw bit, especially a two-sided grinding device simultaneously of sword tooth on the saw bit.

Background

As shown in fig. 1-2, the saw blade comprises a saw blade base body (1) and teeth (2), a plurality of teeth (2) are arranged on the outer edge of the saw blade base body and along the circumferential direction of the saw blade base body, a central hole (3) is formed in the middle of the saw blade base body (1), cutter teeth (4) are welded on the end faces of the teeth (2), two end faces of the cutter teeth (4) are parallel to the end faces of the saw blade base body (1), and the cutter teeth (4) are used for cutting parts and wood. After the cutter teeth (4) are welded on the saw blade base body (1), two end faces of the cutter teeth (4) need to be ground by using a grinding wheel so as to remove oxide skin formed in the process of welding the cutter teeth. The existing mode of polishing the cutter teeth is that a central hole (3) of a saw blade is sleeved on a positioning column from top to bottom, the positioning column is vertically welded on the table surface of a machine table, a worker presses the top surface of the saw blade by using a pressing head after positioning, then the top surface of the cutter teeth is ground by using a grinder, and after each cutter tooth is ground, the cutter teeth rotate around the center of the positioning column for a certain angle so that the next cutter tooth is positioned in a polishing station, and the upper surfaces of all the cutter teeth can be polished by the circular operation; after polishing, workers turn over the saw blade, and the lower surfaces of all the cutter teeth can be polished by repeating the above operations. However, although this grinding method can grind the two end faces of the blade tooth of the saw blade, the following defects still exist: 1. after each end face of all the cutter teeth (4) is ground, the saw blade needs to be turned over again to grind the other end face of the cutter teeth (4), which undoubtedly increases grinding time and reduces grinding efficiency. 2. When the external diameter of saw bit diminishes, the pressure head downstream back can't press the terminal surface of saw bit on, and then leads to unable polishing to the saw bit. Therefore, a grinding device which can improve the grinding efficiency of the cutter teeth and is suitable for grinding saw blades with different diameters is needed.
