Described reference axis external diameter and the internal diameter fit of described benchmark sleeve, the shaft shoulder of reference axis makes the first datum level having for coordinating, and the end face of benchmark sleeve is then provided with second datum level that coordinate corresponding to the first datum level.

Described locking piece includes the some cone tail screws being radially inserted into and be fixed between benchmark sleeve and reference axis by screw thread location structure；Described screw thread location structure is the screw radially running through benchmark sleeve and the taper hole being radially arranged on reference axis, and the axis of described taper hole is parallel to screw axis and keeps some spacing with screw axis.

Described some spacing are 0.3-2.0mm.

It is additionally provided with, between the end face of described benchmark sleeve and the shaft shoulder that coordinates with it, the positioning key structure including positioning key and positioning spline.

The beneficial effects of the utility model are:

One, efficiency is high: coordinated by two screws, easy to operate, and dismounting is quickly；

Two, low cost: overall tool rest can be arranged in pairs or groups from different cutters by fast changing-over, it is not necessary to organize tool rest more；

Three, variation: boring, tapping and face milling stroke, knife-seat can coordinate the cutter that conversion is different, effectively reduces the school cutter time, improves working (machining) efficiency and the automatization level of production line；

Detailed description of the invention

Further illustrate below in conjunction with embodiment shown in the drawings.

Shown in Fig. 5-7, conventional dynamic tool apron includes tool rest body 10, elastic collet chuck 11, lock nut 50 and cutter 13；Tool rest body 10 front end face is provided with a projecting ring section 21, and projecting ring section outside is provided with external screw thread 211；It is provided with the female thread 52 coordinated with external screw thread 211 in lock nut 50, in lock nut, is additionally provided with a taper face 51；Described taper face top press against elastic collet chuck 11, the female thread of lock nut is locked with the external screw thread of tool rest body when coordinating, taper face compresses elastic collet chuck makes it tighten toward center position, and cutter 13 is placed in the central hole location of elastic collet chuck, and resilient sleeve 11 is tightened toward center position and is able to fixed cutting tool.

This dynamic tool apron, dismantles time-consuming when changing cutter, the school cutter time is the longest, does not has modularity to design, relatively costly, the less sample of cutter, in-convenience in use.

The modularity quick-changing type dynamic tool apron that this utility model provides, in addition to for the elastic collet chuck of installing cutter and the locking nut (this part is similar with existing dynamic tool apron) being fixed on by elastic collet chuck on tool rest body, it is also provided with a hydraulic quick coupler 20 that elastic collet chuck and tool rest body quickly can be positioned；In described hydraulic quick coupler, benchmark sleeve 61 is arranged on tool rest body, and the abutting end coordinated with this benchmark sleeve corresponding is arranged in hydraulic quick coupler end, and locking piece is for locking the cooperation position of described benchmark sleeve and abutting end.

Wherein, reference axis 23 external diameter of hydraulic quick coupler abutting end and the internal diameter fit of described benchmark sleeve, arranging the first datum level 22 on the shaft shoulder of hydraulic quick coupler abutting end, tool rest body is provided with the second datum level 62, and the second datum level is positioned at the end face of benchmark sleeve and corresponding to the first datum level coordinates；Described locking piece includes the some cone tail screws 71 (visible in figure: two cone tail screws are arranged symmetrically with) being radially inserted into and be fixed between benchmark sleeve and reference axis by screw thread location structure；Described screw thread location structure is the screw 611 radially running through benchmark sleeve and the taper hole 231 (visible in figure: two screws, two taper holes are all arranged symmetrically with) being radially arranged on reference axis, and the axis of described taper hole is parallel to screw axis and keeps some spacing (preferred distance is 0.3-2.0mm) with screw axis；When two cone tail screw tightenings are in screw, conehead just holds out against in taper hole, produces axially and radially adhesive force and not only makes the second datum level of hydraulic quick coupler the first datum level and tool rest body fit tightly, and the tapering of taper hole also has automatic correction center effect；

Further, being provided with the positioning key 80 and positioning spline 81 that can mutually fasten between tool rest body and the end face of hydraulic quick coupler, this positioning key structure can improve quick location efficiency.

Additionally, described hydraulic quick coupler 20 is provided with projecting ring section 21, and it is provided with external screw thread 211 in projecting ring section 21 periphery；During use, hydraulic quick coupler 20 connects elastic collet chuck 11, the built-in cutter of elastic collet chuck 13, external lock nut 50, taper face 51 and female thread 52 is set in lock nut 50, taper face 51 is less than elastic collet chuck 30, and lock nut 50 female thread 52 then lock onto hydraulic quick coupler 20 projecting ring section 21 external screw thread 211 so that elastic collet chuck fixed cutting tool 40；

From Fig. 8, Fig. 9, Figure 10: after this modularity quick-changing type dynamic tool apron is applied to cutter tower, described cutter can be drilling tool, tapping cutter, end mill cutter or facing cut cutter；The most in hgher efficiency, cost is lower and cutter is diversified.
