(3) summary of the invention
The purpose of this utility model is to provide a kind of machining problem that can solve the pipe joint groove that improves shape, guarantees pipe joint groove crudy, the shape of a saddle vehicle clamper of processing tube joint bevel on general horizontal lathe.
The purpose of this utility model is achieved in that it comprises the clamp body installing and support usefulness, side's cover, rotating shaft, the three jaw self-centering chucks that match with side's cover and the main shaft that three jaw self-centering chucks are installed, three jaw self-centering chucks are provided with transition disc, main shaft is arranged on the spindle drum, spindle drum is provided with bearing bracket stand, bearing bracket stand is provided with journal bearing, and journal bearing withstands on the shape of a saddle pattern by the compression spring.
The utility model also has some technical characterictics like this:
1, described rotating shaft is supported by bearing block assembly, and rotating shaft is provided with and transmits the feather key that moment of torsion is used;
2, described main shaft place is provided with the lining that location and abrasionproof are used;
3, described clamp body is fixed on the horizontal lathe by pressing plate;
4, described compression spring supports and regulates by the spring pull bar.
The utility model course of work is: shape of a saddle vehicle clamper is installed on the corresponding horizontal lathe earlier, it is coaxial with lathe to adjust the anchor clamps center, fixes.With the side's cover on the chuck clamping device on the lathe.Again the shape of a saddle pattern identical with pipe joint shape of a saddle S value is installed on the transition disc of main shaft chuck, fixes.Adjust the degree of tightness of bearing bracket stand, fix.Workpiece can be installed in that centering clamps on the three-jaw chuck of anchor clamps.(elasticity of levelling fine horse saddle type vehicle clamper spring before processing) knife rest on horizontal lathe is loaded onto corresponding lathe tool, does normal cutting and can process the shape of a saddle groove that meets drawing.
The utility model is the vehicle clamper (shape of a saddle vehicle clamper) that a cover particular design is installed on general horizontal lathe, and the realization pipe joint promptly rotates and does straight reciprocating motion clocklike.Lathe tool is only done normal advance and retreat cutter action.The groove that can process the band angle can process shape of a saddle straight section again.
The characteristics of the utility model shape of a saddle vehicle clamper: this shape of a saddle vehicle clamper can make the workpiece of turning attachment clamping promptly rotate and can do the horizontal movement of setting.Lathe tool on the lathe saddle when cutting blade be the shape of a saddle of setting with respect to the track of pipe joint section.Its advantage have following some:
1, solved the unmachinable difficult problem of saddle-shaped pipe joint bevel for welding.
2, improved the machined surface quality on saddle nozzle surface greatly.
3, saddle nozzle is polished to change by machining by the line gas cutting and is made production efficiency improve more than 10 times.
4, this saddle-shape vehicle clamper can be processed the pipe joint of the following different wall of φ 300mm.(satisfying the needs of all products of factory fully)
