Description
Technical field
It the utility model is related to a kind of tool rest tensioning mechanism, specifically a kind of tool rest tensioning mechanism for vertical lathe.
Background technology
In digital control vertical turning center, tool rest and ram to couple the tightening force of form and tool rest on ram big
It is small that conclusive effect is played to the rigid quality of tooling system technique.
The structure type of tool-broaching mechanism has two kinds in the market：
The first is to tense tool rest with standard blind rivet to realize by standard taper shank, for example, with standard BT50 taper shanks with mark
Quasi- P50T-2-MAS403 blind rivets tense tool rest to realize, its structural representation is as shown in figure 1, in Fig. 1, and 1 is 30 degree of blind rivets, and 2 are
BT50 taper shanks, 3 be positioning key（Each one of left and right）, 4 be lathe tool seat, and 5 be pull bar, and 6 be pulling claw, and 7 be ram.
Second is that big T-slot is processed on turning tool rod, the structure type tensed with big T-shaped blind rivet, transition disc
Bottom is fixed with two V-arrangement locating pieces, and the upper end of lathe tool seat offers two V-arrangement positioning spigots, and transition disc and lathe tool seat are V-arrangement
Face tap is touched, and its structural representation is as shown in Fig. 2 in Fig. 2, and 1 is pull bar, and 2 be T-shaped blind rivet, and 3 be V-arrangement positioning spigot, and 4 are
Lathe tool seat, 5 be turning tool rod, and 6 be transition disc, and 7 be ram.
The structure type of both the above tool-broaching mechanism, the tightening force of the first routinely blind rivet standard can only provide, and connect
Contacting surface only has BT50 taper shank part, and one side broach force is small, and another aspect contact surface is single, the cutting that can be born in processing
Power is not big enough, tends not to the processing request for meeting big cutting output.Second of blind rivet is a larger T-shaped blind rivet, contact
Face is double V-shaped groove structures, although larger broach force can be realized, the manufacture difficulty of cutter is larger, it is impossible to standardization is realized,
And during automatic tool changer turning tool rod flexible stroke it is big, tool change time length, and be not easy to repair, interchangeability is poor.
