Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Example 1
As shown in fig. 1 to 3, a circular blade mounting apparatus includes a tool bar 1, a pressing plate 2, a pressing plate screw 3, a circular blade 4, and a spacer 5.
The front end of cutter arbor 1 is provided with and is used for the installation blade mounting groove 6 of circular blade 4, gasket 5 set up in the bottom of blade mounting groove 6, the lower terminal surface of circular blade 4 is provided with positioning groove 7, be provided with the matching on the gasket 5 positioning groove 7's boss 8.
The pressing plate screw 3 is in threaded fit with the cutter bar 1, and the pressing plate 2 is pressed on the upper end face of the circular blade 4 downwards through the pressing plate screw 3.
The circular blade is a cylindrical circular blade, the gasket is a cylindrical gasket, the boss is a cylindrical boss, and the positioning groove is a cylindrical groove.
In other embodiments, the upper end surface of the circular blade is also provided with a positioning groove, so that the circular blade can be turned over for use, and the utilization efficiency is further improved.
