Abstract
The utility model discloses a tapping chuck quick change positioning device, which is characterized in that: the positioning device includes a handle (1), the outer wall of the handle (1) is provided with two limit check rings (2), the outer wall of the handle (1) lower end is provided with a sliding sleeve (4), the sliding sleeve (4) is limited through the two limit check rings (2), the outer wall of the handle (1) is provided with two steel balls (3), the steel balls (3) are located inside the sliding sleeve (4), and a quick change chuck (5) is arranged inside the handle (1). The tapping chuck quick change positioning device is simple in structure and easy in use, can improve the thread processing efficiency, prevents screw tap broken caused by the situations of encounter of hard points or having a different center with the tapping hole in a processing course, and can guarantee an effective thread depth in the process of blind hole thread processing.
Description
Technical field
The utility model relates to the quick change positioner in the tapping process of part boring back, can be widely used in the processing of mechanical processing industry part, is particularly useful for the processing technique field that part is attacked blind hole or minor thread hole.
Background technology
At present the collet screw tap that is fixedly clamped is adopted in the processing of the screw thread after the boring (being commonly called as tapping) usually in the mechanical processing industry, and screw thread process plug tap prolongs axially-movable, and it does not radially have drift, belongs to rigidity and connects.Its shortcoming be in process, run into hard spot or with the tapping hole decentraction, will cause screw tap to fracture, in blind threaded process, can't guarantee the effective thread degree of depth.
Summary of the invention
The purpose of the utility model be exactly be directed against more than the deficiency of existing technology, propose a kind of simple and practical, the tap holder quick change positioner that screw tap can fracture during processing.
The technical scheme that the utility model adopts is following:
A kind of tap holder quick change positioner; It is characterized in that it comprises handle of a knife, the outer wall of handle of a knife is equipped with two spacing back-up rings, and the bottom outer wall of handle of a knife is equipped with sliding sleeve; Said sliding sleeve is spacing through two spacing back-up rings; Outer wall at handle of a knife is provided with two steel balls, and steel ball is positioned at the sliding sleeve inboard, and handle of a knife inside is equipped with quick chuck.
The lateral wall of said quick chuck is provided with the groove that matches with said steel ball.
The spacing hole of said steel ball is inner small and outside big bellmouth orifice.
The beneficial effect of the utility model is:
Simple in structure, easy to use, can improve the screw thread working (machining) efficiency, avoid occurring the situation that runs into hard spot in the process or cause screw tap to fracture, and can in blind threaded process, guarantee the effective thread degree of depth with the tapping hole decentraction.
Description of drawings
Fig. 1 is the structural representation of the utility model assembly.
Fig. 2 changes the screw tap structural representation for the utility model.
Fig. 3 changes the screw tap structural representation for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in Fig. 1-3, its composition of the utility model comprises: 1, handle of a knife, 2, spacing back-up ring (up and down each), 3, steel ball (each one of symmetric position), 4, sliding sleeve, 5, quick chuck, 6, the M6 screw tap.2 pairs of sliding sleeves of wherein spacing back-up ring are position-limiting action about in the of 4; Steel ball 3 embeds in the quick chuck stopper slot, 5 axially-movables of restriction quick chuck; Sliding sleeve aperture medial surface makes steel ball embed the quick chuck stopper slot.
The operation principle of the utility model is following: when part begins machining screw; Because there is the gap in steel ball 3 with quick chuck 5; Therefore M6 screw tap 6 can prolong the drift of bottom outlet direction when axially-movable, makes screw tap and bottom outlet concentric, and this quick chuck 5 flexibly connects with being connected to of handle of a knife 1.When needing to change screw tap; Shown in figure two: sliding sleeve moves in the direction of arrows, and steel ball 3 spacing holes are inner small and outside big bellmouth orifice, and steel ball 3 prolongs outside the inclined-plane and moves (can not drop by sliding sleeve 4 macropore inner wall limits); The quick chuck that loses restriction falls naturally, 1～2 second time; Then by shown in Figure 3: the quick chuck band screw tap with new, prolong on the direction of arrow and move, steel ball spacing hole on the quick chuck is higher than on the handle of a knife behind the aperture, put down sliding sleeve.Sliding sleeve aperture inwall promotes steel ball and embeds in the quick chuck stopper slot, and the restriction quick chuck drops, and 1～2 second time, a tool changing is accomplished.
Other undeclared part that the utility model relates to is identical with prior art.
