Summary of the invention

Main purpose of the present utility model is that providing a kind of can adjust the central point of tapping cutter on the tooth attacking device axial line, the correctness when guaranteeing to operate.

For achieving the above object, this the utility model adopts following design: a kind of tooth attacking device with adjustment function, mainly comprise holding and establish a body and a tapping cutter, wherein this tapping cutter is arranged in and holds in the seat groove of establishing body one end, and the contact by locking screw, make its location, be primarily characterized in that:

This holds the seat groove periphery both sides of establishing body and is provided with the screw of establishing for locking screw lock, be provided with two otch in the periphery radial cut in addition, the both sides of this otch are provided with groove, laterally be equipped with open-work on it, wherein the open-work of a side is provided with the internal thread that wears the lock knot for an adjustment screw, has breach at the rear side with respect to otch, and it mainly is set as two parts by otch with this groove branch, cooperate the size that screws and loosen the adjustment otch of adjusting screw, and then reach the effect of adjustment.

Adopt above-mentioned design, the utility model is in holding the otch that the periphery of establishing body front end seat groove is provided with two or more, and the both sides of this otch then are penetrated with open-work, and can cooperate adjustment screw lock to establish it, by the adjustment of screw, to reach accurate effect.

Below in conjunction with drawings and Examples, structure of the present utility model and advantage are further described.

The specific embodiment

See also Fig. 3, the utility model tooth attacking device 2 mainly comprises holding establishes a body 21 and a tapping cutter 22, wherein:

One holds and establishes body 21, it is the cylinder of a hollow, its front end is provided with a groove 211, be provided with screw 212 in its periphery both sides, can establish for a locking screw 218 locks, be provided with two or more otch 213 in addition in the radial cut of periphery, the both sides of this otch 213 are provided with groove 214, also laterally be equipped with open-work 215 on it, the open-work 215 of a side and be provided with internal thread wherein, can for one adjust screw 217 wear the lock knot, have breach 216 at rear side with respect to otch 213, it mainly had been set as two parts in 211 minutes by otch 213 with this groove, made it have the effect of adjustment;

One tapping cutter 22, it is arranged in and holds in the seat groove 211 of establishing body 21, and its body is a threading tool seat 220, its external diameter is slightly less than the internal diameter of a groove 211, be embedded with outer threading tool 221 on this threading tool seat 220, be provided with shrinkage pool 222 in its outboard peripheries in addition, can be for the contact of locking screw 218.

Structure as above, can provide workpiece to attack the externally threaded function of system, after tapping cutter 22 is inserted a groove 211, be resisted against the shrinkage pool 222 of tapping cutter 22 by the tail end of locking screw 218, make it be positioned also can prevent its rotation in the groove 211, yet it is improper if lock is established, this moment, the central point of this tapping cutter 22 can produce the phenomenon (as shown in Figure 4) of skew with the central point of seat groove 211, this moment then can be by screwing or loosening this adjustment screw 217 to control the size of otch 213, and then the internal diameter size of change seat groove, and tapping cutter 22 is adjusted to the tram, the correctness (as shown in Figure 5) when making screw thread to guarantee to attack.
