Embodiment Construction

[0016] Such as Figure 1 to Figure 3 The shown drilling bit includes a cutter body, a drill 2 and a stopper 3. The cutter body is a connection part 11, a mounting part 12 and a cutter bar part 13 from top to bottom, and the drill cutter 2 is connected to the cutter bar part 13. lower end;

[0017] The first chip removal flute 14 and the second chip removal flute 15 opposite and spirally arranged are provided on the cutter bar part 13, and the first chip removal flute 14 and the second chip removal flute 15 extend from the end surface of the cutter bar part 13 to the mounting part 12;

[0018] When the drill bit is drilling, chips can be discharged outwards along the first chip flute and the second chip flute, thereby avoiding the generation of clogging caused by chips and improving the working efficiency of the present invention.

[0019] The limit device 3 comprises a limit sleeve 31 and a set screw 32, the limit cover 31 can be screwed on the knife bar portion 13, the limi...

Abstract

The invention discloses a drilling machine drill bit which comprises a tool body, a drilling tool and a limiting device. The tool body comprises a connecting part, an installation part and a tool rodpart in sequence from top to bottom. The drilling tool is connected to the lower end of the tool rod part. A first chip discharging groove and a second chip discharging groove which are spirally arranged and are opposite are formed in the tool rod part, and the first chip discharging groove and the second chip discharging groove extend to the installation part from the end portion of the tool rodpart. The limiting device comprises a limiting sleeve and a fixing screw, the limiting sleeve is rotationally connected to the tool rod part, the limiting sleeve is provided with a threaded hole, andthe limiting sleeve is fixed to the tool rod through the fixing screw. During drilling, the position of the limiting sleeve is adjusted, when drilling is conducted to the position of the limiting sleeve, continuous drilling is stopped, and therefore the purpose of controlling the drilling depth is achieved, and the phenomenon that a hole site is not in place or a hole is through is avoided. The drilling machine drill bit is applied to drilling mechanical equipment.

Description

technical field [0001] The invention relates to a drilling machine mechanical equipment, in particular to a drilling bit. Background technique [0002] A drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills mainly include twist drills, flat drills, center drills, deep hole drills and casing drills. During the use of the drill bit, it is difficult to accurately judge the depth of the drilled hole, which may easily cause the hole to be out of place, or the phenomenon of through-hole. Contents of the invention [0003] The object of the present invention is to provide a drill bit for a drilling machine, which can accurately control the drilling depth of the drill bit, so as to solve the problem that the hole is not in place or the hole is through. [0004] The technical solution adopted in the present invention is: a drill bit for a drilling machine, including a cutter body, a drill and a limiting dev...
