Through can reduce the smear metal that the chamfer in-process produced to the wearing and tearing of elasticity post at elasticity post externally mounted protecting crust, dodge the setting in clearance moreover and can dodge elasticity post and cutter body swing, also can prevent simultaneously because of excessive swing, lead to the elasticity post to receive the damage, and then increase of service life.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is another schematic structural diagram of the present invention.
Detailed Description
The chamfering tool shown in fig. 1 and 2 comprises a connecting shaft 1, wherein the connecting shaft 1 is connected with an elastic column 2, the elastic column 2 is connected with a tool body 3 through a rotation stopping pin, the connecting shaft 1 is further connected with a cylindrical protective shell 4 with a cavity in the middle, a through hole 7 is formed in the bottom of the protective shell 4 and used for inserting the tool body 3, the protective shell 4 is positioned outside the elastic column 2, an avoiding gap 5 is reserved between the protective shell 4 and the elastic column 2, the avoiding gap 5 is reserved between the protective shell 4 and the tool body 3, the bottom of the protective shell 4 inclines downwards, a through hole 6 is formed in the shell of the protective shell 4, an inlet of the through hole 6 is positioned at the upper end of the protective shell 4, an outlet of the through hole 6 is positioned on the wall surface of the through; the bottom of the cutter body 3 can be detachably connected with a cutter head 8.
During installation, the elastic column 2 is fixed on the connecting shaft 1 firstly, the protective shell 4 is connected or the cutter body 3 is inserted again, the cutter head 8 is connected with the bottom of the cutter body 3 through threads, the elastic column 2 can be protected through the protective shell 4, meanwhile, the swinging of the elastic column 2 can be limited, the optimal maximum swinging angle is 5 degrees, the cutter head 8 can be replaced without detaching the cutter body 3 through the threads of the cutter body 3 and the cutter head 8, the trouble caused by repeated detachment of the protective shell 4 and the cutter body 3 is omitted, and the rotating direction when the cutter head 8 is screwed up is opposite to the rotating direction when the cutter head 8 works.
In addition, as shown in fig. 1, a threaded hole is formed in the top of the protective shell 4, and the protective shell 4 is in threaded connection with the connecting shaft 1 through the threaded hole; the inlet of the conducting hole 6 is positioned on the wall surface of the threaded hole, the middle of the connecting shaft 1 is provided with a conducting cavity 9, and when the protective shell 4 is connected with the connecting shaft 1, the conducting cavity 9 is communicated with the conducting hole 6; specifically, the top of the protective shell 4 is provided with a first positioning block 4-1, the side of the connecting shaft 1 is provided with a second positioning block 1-1, when the first positioning block 4-1 contacts with the second positioning block 1-1, the conduction cavity 9 is communicated with the conduction hole 6, namely when the protective shell 4 is installed on the connecting shaft 1 through threads, the first positioning block 4-1 gradually rises until the protective shell contacts with the second positioning block 1-1 to stop rotating the protective shell 4, and meanwhile, the conduction cavity 9 is communicated with the conduction hole 6.
