Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
Referring to fig. 1-3, a drill bit for processing high-precision holes comprises a main body 1, wherein a fixing mechanism 3 is fixedly mounted at one end of the main body 1, the fixing mechanism comprises a front fixing block 6 and a rear fixing block 9, a clamping groove 7 is formed at one end of the front fixing block 6, a first clamping block 5 is fixedly mounted at the center of one end of the front fixing block 6, a plurality of threaded holes 8 are formed at the position, close to the edge, of one end of the front fixing block 6, a bolt 13 penetrates through a unthreaded hole 12 to be in threaded connection with the threaded holes 8, a second clamping block 10 is fixedly mounted at one end of the rear fixing block 9, a circular groove 11 is formed at the position, close to the edge, of one end of the;
further, the other end of the rear fixing block 9 is fixedly provided with a fixing tail 2;
further, a drill 4 is fixedly installed at one end of the main body 1.
The working principle is as follows: when the device is used, the front fixing block 6 and the rear fixing block 9 in the device are combined, and then the front fixing block and the rear fixing block are fixed through the bolts 13, so that the splicing of the device is realized;
this kind of setting differentiates whole integrative structure into two structures, promotes the variety of whole device, appears damaging in the middle part of whole device moreover, can change to front end portion in the device, and then rear end portion repeatedly usable has saved the cost.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
