A kind of CNC milling machine, it is characterised in that: including a kind of CNC milling machine turnning and milling positioning device described in above-mentioned any one.
By the above-mentioned description of this invention it is found that compared with prior art, a kind of CNC milling machine turnning and milling provided by the invention
Positioning device and CNC milling machine, have turnning and milling double-purpose functional, and the locating piece conical surface and knife plate the taper hole cooperation of positioning pin can be achieved
It fits closely, locating piece and cone hole machine aperture error, the mounting height error of knife plate, accurate positioning, double positioning pins can be eliminated
Setting ensure that the intensity and accuracy of location structure, guarantee equipment processing quality.
Detailed description of the invention
Fig. 1 is a kind of CNC milling machine partial structural diagram of the present invention.
Fig. 2 is a kind of CNC milling machine partial profile structure of the present invention.
Fig. 3 is pin of the present invention and knife plate partial profile structure.
It is as follows that correspondence is identified in figure: lathe tool 1, positioning pin 3, abutment sleeve 31, perforation 311, spring 32, is determined main shaft end cap 2
Position block 33, the conical surface 331, positioning region 332, pin 34, knife plate 4, taper hole 41.
Specific embodiment
Below by way of specific embodiment, the invention will be further described.
Referring to figs. 1 to shown in Fig. 3, a kind of CNC milling machine has turnning and milling double-purpose functional, including CNC milling machine turnning and milling positioning dress
It sets, which is used to limit the rotation relative to main shaft end cap 2 of lathe tool 1, including positioning pin 3, knife
Plate 4, knife plate 4 are detachably arranged on lathe tool 1.
Positioning pin 3 includes abutment sleeve 31, spring 32, locating piece 33, and locating piece 33 is telescopic to be set to abutment sleeve 31
Interior, spring 32 is set in abutment sleeve 31, and spring 32 provides the elastic force that locating piece 33 stretches out abutment sleeve 31, and locating piece 33 stretches out
Portion is formed with the conical surface 331 reduced outward, and knife plate 4 is equipped with the taper hole 41 cooperated with 33 conical surface 331 of locating piece, positioning pin 3 one
End is connect with main shaft end cap 2, and the other end is cooperatively connected by locating piece 33 and knife plate 4, and then limits lathe tool 1 with respect to main shaft end cap
2 rotations, abutment sleeve 31 are equipped with perforation 311, and locating piece 33 is equipped with the positioning region 332 greater than 311 aperture of perforation, perforation
311 set there are two, symmetrically on the barrel of abutment sleeve 31, positioning region 332 is two cotter slots, two pins for two perforation 311
Nail slot is symmetrically arranged on locating piece 33, and pin 34 passes through perforation 311 and enters positioning region 332, makes locating piece 33 can be in abutment sleeve
