Abstract
A chuck body structure comprises a through hole formed in the axial direction of a chuck body and used for containing a broach and is characterized in that a pin hole extending in the radial direction of the chuck body is formed on the outer circumferential surface of the chuck body; a positioning pin is inserted into the pin hole; and the positioning pin penetrates through the whole through hole and the broach is arranged on the positioning pin. The chuck body structure has a simple structure and can fix the position of the broach and prevent the broach from sliding down; moreover, the iron scraps in the production process can be conveniently discharged, the production efficiency is improved, and the work of a broaching machine is more stable and smooth.
Description
Technical field
The utility model relates to a kind of collet body structure, particularly relates to a kind of collet body structure of broaching machine.
Background technology
Collet body is a vitals of broaching machine, has clamped broaching tool in the collet body.For fixing broaching tool position better, make broaching tool be difficult for gliding, as shown in Figure 1, can in the through hole 11 ' in collet body 1 ' step surface 2 ' be set usually, the end of broaching tool is positioned on the step surface 2 ', and broaching tool is positioned.This collet body structure that is provided with step surface, higher to the required precision of step surface, be difficult for processing; In use, iron filings are prone to amass in the step surface place, are unfavorable for chip removal; Influence the correct location of broaching tool in collet body, make broaching unstable smooth and easy, cause production efficiency to reduce.
Summary of the invention
The utility model technical problem to be solved provides a kind of collet body structure of locating the broaching tool position and being convenient to chip removal be convenient to.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of collet body structure; Comprise and be positioned at the axial through hole that is used for ccontaining broaching tool end of collet body; It is characterized in that: offer the pin-and-hole that radially extends along said collet body on the said collet body; Be inserted with alignment pin in the said pin-and-hole, the end of broaching tool promptly is shelved on the said alignment pin, and has the gap between the inwall of the both sides of alignment pin and said through hole.This alignment pin not only can be located broaching tool, and the discharge of the iron filings of being convenient to produce in the production process.
In order to be convenient to discharge iron filings more; Said through hole is divided into first less through hole of diameter and the second bigger through hole of diameter; The diameter of said first through hole and the end of broaching tool are complementary and are used for the end of ccontaining broaching tool, and said pin-and-hole and alignment pin are positioned at the junction of this first through hole and second through hole.
Compared with prior art, the advantage of the utility model is that this collet body architecture is simple, not only can locate the broaching tool position; Prevent the downward slippage of broaching tool; And can be convenient to discharge the iron filings that produce in the production process, improved production efficiency, make the more stable work of broaching machine smooth and easy.

Fig. 1 is a collet body structure of the prior art.
Fig. 2 is the phantom of the collet body structure of the utility model.
Fig. 3 is the cutaway view along A-A line among Fig. 2.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The collet body structure of the utility model; Shown in Fig. 2-3, collet body 1 is a middle structure with axially extending bore 11 among this figure, and the end of broaching tool is that inserting is in this through hole 11; Have the pin-and-hole 2 that radially extends on this collet body 1, be inserted with alignment pin 3 in the said pin-and-hole 2 along collet body 1.Alignment pin 3 radially passes whole through hole 11; The end of broaching tool 5 just is shelved on this alignment pin 3; And has gap 4 between the inwall of the both sides of alignment pin 3 and said through hole 11; Therefore alignment pin 3 not only can be fixed on certain position with broaching tool, prevent broaching tool 5 collet body 1 in to slippage down, and two side clearances 4 that the iron filings that in motion process, produce of broaching tool can be through alignment pin 3 are downwards and discharge from collet body 1.
And preferably; This through hole 11 is divided into the first less through hole 12 and the second bigger through hole 13 of diameter of diameter; The end of the diameter of this first through hole 12 and broaching tool 5 is complementary and ccontaining broaching tool end; This pin-and-hole 2 and alignment pin 3 are located in the junction of first through hole 12 and second through hole 13, can be convenient to more like this discharge to second through hole 13 slit of iron filings between broaching tool end and collet body 1.
This collet body structure not only can be located the broaching tool position and prevented that broaching tool from gliding, and the downslide of the iron filings of being convenient to produce in the broaching tool running is discharged.And this structure is processed and assembling is all very convenient, has improved production efficiency.
Except that the foregoing description, the utility model also includes other embodiments, and the technical scheme that all employing equivalents or equivalent substitute mode form all should fall within the protection domain of the utility model claim.
