Description
Technical field
the utility model relates to machine tools technical field, specifically relates to centrre rest.
Technical background
When to flat part or short part calibration, directly grab chuck with three on dividing head and clamp; When carrying out calibration to slender type part, a centrre rest must be had to support the slender axles other end.In prior art, head part is varied, but have there is complex structure, awkward shortcoming, the shortcoming with low precision also had, have impact on the result of use of top.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides the centrre rest that a kind of flexible operation, structure are simple, precision is high.
The technical solution of the utility model is achieved in that a kind of centrre rest, comprise base, below base, there is mounting structure, there is in the middle of base the hole of installing screw mandrel, and screw mandrel is installed, there is handwheel in the outside of screw mandrel, and screw mandrel also has silk braid to be arranged on screw mandrel in the inboard of base, and submounts is slide unit, on slide unit, slide block is installed, install top before slide block, install pulling part above silk braid, pulling part stretches out the upper surface of slide unit and connection sliding block.
Say further, described front of chassis is provided with locking stud, and described locking stud is through base side, and locking stud has the projection of involute pattern, rotational lock stud projection heads on head part.
Say further, described top and slide block activity is installed.
Say that described handwheel has index dial further.
The beneficial effects of the utility model are: such centrre rest has flexible operation, structure is simple, precision is high advantage;
Described front of chassis is provided with locking stud, and described locking stud is through base side, and locking stud has the projection of involute pattern, rotational lock stud projection heads on head part, has fixing more firmly advantage;
Described handwheel there is index dial, there is the more accurate advantage of use;
Described top and slide block activity is installed, and described toply have the centre head that can change above, has the advantage that can change.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional schematic.
Fig. 2 is A-A cross-sectional view of Fig. 1.
Wherein: 1, base 2, mounting structure 3, screw mandrel 4, handwheel 5, silk braid 6, slide block 7, top 8, pulling part 9, locking stud.
specific embodiments:
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of centrre rest, comprises base 1, there is below base mounting structure 2, have the hole of installing screw mandrel in the middle of base, and install screw mandrel 3, there is handwheel 4 in the outside of screw mandrel, screw mandrel also has silk braid 5 to be arranged on screw mandrel in the inboard of base, submounts is slide unit, is provided with slide block 6 on slide unit, installs top 7 before slide block, silk braid 5 above installs pulling part 8, and pulling part stretches out the upper surface of slide unit and connection sliding block.
When rotating handwheel 4, be with movable slider 6 to move left and right by screw mandrel 3 and silk braid 5, thus hold out against or loosen workpiece, whole parts are arranged on platen and locate.
As shown in Figure 2, say further, described front of chassis is provided with locking stud 9, and described locking stud is through base side, and locking stud has the projection of involute pattern, rotational lock stud projection heads on head part, and slide block 6 relies on locking stud 9 to lock
Say further, described top and slide block activity is installed.
Say that described handwheel has index dial further.
Above embodiment is only section Example of the present invention, but aim of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the change done or modification and further expansion are all encompassed in the scope of the claims of the present invention.
