Description
Technical field
The utility model relates to a kind of gearshift of Digit Control Machine Tool gear type main shaft, belongs to machine tool chief axis transmission field.
Background technology
Lathe double speed gear is used for main shaft of numerical control machine tool transmission, requires two speed ratios and is applied to respectively at a high speed and low-speed running two kinds of occasions, moment of torsion when object is the constant power that expansion motor produces and increases low-speed running.Current machine tool gear mechanism hydraulic pressure realizes gearshift, and impact large during gearshift, and need configure Hydraulic Station, cost is high.
Utility model content
The purpose of this utility model is the gearshift providing a kind of Digit Control Machine Tool gear type main shaft, shift gears reliable and stable, effectively prevent from using the problem that air pressure gearshift is unstable, easily fall gear, there is impact little, cheap, be easy to the advantage ensureing to complete gear shifting action within the system requirements time.
For achieving the above object, the utility model is achieved through the following technical solutions:
The gearshift of the Digit Control Machine Tool gear type main shaft that the utility model provides, comprise air pressure gearshift cylinder, air pressure gearshift cylinder is fixed on gearshift jar support, gearshift jar support is fixed on the upper surface of gear type head, air pressure gearshift cylinder upper end is provided with Bracket for Inspection, the upper and lower of Bracket for Inspection is respectively equipped with proximity switch, the upper end of piston rod is provided with detection block, detect block between two proximity switches, the lower end of piston rod is provided with gearshift shifting block, and gearshift shifting block is fixedly connected by driving lever clamp nut and shift lever.The state of proximity switch moment detection piston rod, when can't detect, make-up gas immediately, effectively prevents the problem of gearshift instability, gear shift.
Piston rod top is provided with screw thread, and screw thread is provided with two clamp nuts, and clamp nut is located at respectively and detects above and below block.The position detecting block is regulated by the position adjusting clamp nut, convenient during debugging lathe.
Inlet end and the outlet side of air pressure gearshift cylinder are respectively equipped with throttle grverning valve.
Gearshift shifting block top is provided with groove, the bottom of groove seized piston bar, is provided with shifting block clamp nut below gearshift shifting block.
The utility model compared with prior art, has following beneficial effect:
Digit Control Machine Tool gear type main shaft gearshift of the present utility model, shifts gears reliable and stable, impacts little, cheap, is easy to the advantage ensureing to complete gear shifting action within the system requirements time.
