Abstract
The utility model discloses a swiveling tool rest mechanism of a double column vertical lathe, which comprises a tool rest sliding seat, a revolving sliding seat, a ram and a manual rotating mechanism, wherein the manual rotating mechanism comprises a bracket, a manual mechanism shaft arranged in the bracket and a hollow worm fixed on the manual mechanism shaft; the revolving sliding seat is provided with an arc guide slot and a tooth ring section meshed with the hollow worm of the manual mechanism shaft; and the tool rest sliding seat is provided with an extended connecting part which makes rotational motion of 70 to 92 degrees along the arc guide slot of the revolving sliding seat. By adopting the swiveling tool rest mechanism of the double column vertical lathe, taper range for processing workpieces is wider, therefore, all workpieces within the processing taper range of a machine tool can be processed, thus saving the time of clamping for a plurality of times, improving the production efficiency and being easy to guarantee the processing precision of the workpieces.
Description
Technical field
The utility model relates to vertical lathe, relates in particular to the swivelling tool-holder mechanism of double column vertical lathes.
Background technology
Double column vertical lathes can be at disk, cylinder class part in large-size machine, large-scale pump valve, communications and transportation, shipbuilding and the construction machinery industry, as big part such as motor casing, pump valve housing, wheel hub, carry out the processing that turning processing, upright knife rest degree of pulling such as plane, inside and outside circle cylinder, grooving carry out the turning of interior male cone (strobilus masculinus).Existing double column vertical lathes comprises portal frame, crossbeam, workbench and the upright knife rest that can move back and forth along the crossbeam level, have upper rail face and lower guideway face on the crossbeam, upright knife rest comprises tool-slide, ram and ram balancing cylinder, tool-slide has upper saddle arm and lower slider arm, the upper saddle arm of tool-slide contacts with crossbeam upper rail face, and the lower slider arm of tool-slide contacts with crossbeam lower guideway face.Such structure has increased the processing and loading clamp number of times, influences production efficiency, and the machining accuracy of workpiece also is difficult to guarantee.
The utility model content
Technical problem to be solved in the utility model is: the swivelling tool-holder mechanism that a kind of double column vertical lathes is provided, the swivelling tool-holder mechanism of this double column vertical lathes is installed on the double column vertical lathes and can reduces the processing and loading clamp number of times, enhance productivity, be easy to guarantee the machining accuracy of workpiece.
Solve this technical problem, the technical solution of the utility model is: a kind of swivelling tool-holder mechanism of double column vertical lathes, it comprises tool-slide, rotary slide base, ram and manual rotating mechanism, described manual rotating mechanism comprises the man-operated mechanism axle in the support, support and is fixed on hollow worm screw on the man-operated mechanism axle, described rotary slide base be provided with the circular arc gathering sill and with the gear ring section of the hollow worm engaging of manual rotating mechanism, described tool-slide have stretch out produce the connectors that rotatablely move of 70～92 degree along the circular arc gathering sill of rotary slide base.
The connector of described tool-slide is 82 degree along the anglec of rotation of the circular arc gathering sill of rotary slide base.
The hollow worm screw of described manual rotating mechanism is provided with the alignment pin that is connected with the man-operated mechanism axle.
Adopt the swivelling tool-holder mechanism of the such double column vertical lathes of the utility model, processing work has bigger range of taper, thus the workpiece in the machine tooling range of taper can process, saved the time of multiple clamping, enhance productivity, be easy to guarantee the machining accuracy of workpiece.
Description of drawings
Below in conjunction with accompanying drawing the big whirligig of knife rest of the utility model double column vertical lathes is done explanation in further detail:
Fig. 1 is the swivelling tool-holder mechanism installation site structural representation of the utility model double column vertical lathes;
Fig. 2 is that manual rotating mechanism shown in Figure 1 connects enlarged diagram;
In Fig. 1, Fig. 2,1, rotary slide base; 2, circular arc gathering sill; 3, manual rotating mechanism; 4, tool-slide; 5, ram; 6, hollow worm screw; 7, alignment pin; 8, support; 9, man-operated mechanism axle.
The specific embodiment
As Fig. 1, shown in Figure 2, a kind of swivelling tool-holder mechanism of double column vertical lathes, comprise tool-slide 4, rotary slide base 1, ram 5 and manual rotating mechanism 3, described manual rotating mechanism 3 comprises support 8, man-operated mechanism axle 9 in the support 8, the alignment pin that is fixed on the hollow worm screw 6 on the man-operated mechanism axle 9 and connects hollow worm screw 6 and man-operated mechanism axle 9, described rotary slide base 1 be provided with circular arc gathering sill 2 and with the gear ring section of hollow worm screw 6 engagement of manual rotating mechanism 3, described tool-slide 4 has the circular arc gathering sill 2 along rotary slide base 1 that stretches out and produces the connector that rotatablely moves.The anglec of rotation between tool-slide 4 and the rotary slide base 1 is 70～92 degree, and the anglec of rotation between tool-slide 4 and the rotary slide base 1 adopts 82 degree usually.
Turn the man-operated mechanism axle by spanner, driving hollow worm screw rotates, the final certain angle of rotary slide base left rotation and right rotation that drives, satisfy the requirement of processing work tapering, processing work has bigger range of taper like this, thus the workpiece in the machine tooling range of taper can process, saved the time of multiple clamping, improve production efficiency, be easy to guarantee the machining accuracy of workpiece.
