Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cutaway view (part) of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1.
A kind of plastic extruder machine barrel super large helical pitch inner vortex processing unit (plant); Be used for and the supporting use of data screw milling machine; It comprises base plate 7, supporting base 8 and power set 10, and supporting base 8 can be installed on the base plate 7 with power set 10, and power set 10 also can be installed in addition on lathe bed or other position of numerical-control screw rod milling machine and for miniature milling head power are provided; During practical implementation; Power set 10 can adopt by motor-driven mechanical stepless transmission, and this mechanical stepless transmission also is installed on the base plate 7, on its output shaft output pulley is installed.Base plate 7 can be fixed on the CNC milling machine through the clamping device of routine during use, finishes using and can from the data milling machine, base plate 7 be taken off, and CNC milling machine normally uses.In the described supporting base 8 support bar 6 is installed; But support bar 6 is hollow-core construction; Also can adopt utility structure, its adjustable positions on supporting base 8, as shown in Figure 1; Outside the equal Extension support seat 8 in its two ends; Belt wheel 11 (two troughs of belt of belt wheel 11 usefulness) is installed on one end of support bar 6, and belt wheel 11 links to each other with the output shaft of power set 10 through first driving-belt 12 (can adopt circular arc synchronous cog belt or common driving-belt) on the one hand, and another stretches into power wheels on the miniature milling head 4 (can directly purchase from market) on the end in the machine barrel 5 and links to each other and rotate so that drive miniature milling head 4 with being installed in support bar 6 through second driving-belt 9 (preferably adopting the stationarity of circular arc synchronous cog belt with the assurance transmission) on the other hand; Be symmetrily processed with skewed slot on the end in support bar 6 stretches into machine barrel 5; Bevel back-up block 3 is installed in the described skewed slot, and bevel back-up block 3 can adopt bakelite to make, and the big end of bevel back-up block 3 is used for offseting with machine barrel 5 inwalls and prevents that jitter phenomenon from appearring in processing so that work in-process plays support bar 6 supported; The small end of bevel back-up block 3 and adjustment screw 1 offset; Adjustment screw 1 is installed in regulates on the support 2, regulates support 2 and is installed on the end face that support bar 6 stretches into the end in the machine barrel 5, as shown in Figure 2.In addition, also can be on support bar 6 during practical implementation, the installed inside of described second driving-belt 9 has the regulating wheel that makes 9 tensionings of second driving-belt.
