Description
Technical field
The present invention relates to lathe preventer field, particularly relate to a kind of machine chuck power-off preventer.
Background technology
General horizontal lathe is a kind of widely used Metal Cutting Machine Tool in mechanical processing industry, and operator is at lathe
During processing workpiece, it is easiest to occur that the position of security incident is chuck.
If the adjustment of clutch friction plate gap is improper or the abrasion of clutch handle position portion causes location in main spindle box
Unreliable, even if clutch handle is placed in centre position, mair motor is in "on" position, although now main shaft stops operating,
Owing to the non-power-off of mair motor is still in rotation status, during chuck workpiece loading and unloading, chuck is possible to due to the driving by external force
Suddenly rotate.Even if each position of clutch is the most working properly, when chuck handle inserts chuck workpiece loading and unloading, if imprudence is touched
Clutch handle also can make chuck rotate suddenly.
Summary of the invention
For the problem of shortcomings and deficiencies in prior art, the present invention proposes a kind of machine chuck power-off preventer,
Touch travel switch by change rotation and cause power-off at once, it is ensured that clamping safety when changing workpiece in chucking work.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of machine chuck power-off preventer, including guard shield one, guard shield two, change, main shaft end cap, main spindle box, travel switch
Box, travel switch, cover plate and spacer pin, described guard shield one fixed by screw with guard shield two, and guard shield two is fixed by screws in
In change；Described main shaft end cap is fixed by screws on main spindle box, and spindle end lid is provided with spacer pin, sets outside described change
Having arcuate groove, change is by inner hole sleeve on spindle end lid, and spacer pin is stuck in arcuate groove；Described main spindle box is provided with cover plate,
Travel switch box is fixing on the cover board, and travel switch is arranged on travel switch box.
Further, described main shaft end cap cylindrical is provided with step.
Further, described change profile is for cutting circle, and its endoporus uses matched in clearance with main shaft end cap step cylindrical.
Further, described guard shield one is further fixed on handle.
There is advantages that and protective cover is set on chuck, play security protection in chuck rotary work
Effect；Change uses matched in clearance with main shaft end cap, it is ensured that change can rotate to it；When machine chuck works, pass through
Spacer pin in arcuate groove can rotate position-limiting action to change, it is ensured that guard shield covers chuck.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention；
Fig. 2 is the Section A-A figure of Fig. 1;
Fig. 3 is ring revolving structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, people in the art
The present invention can be made various changes or modifications by member, and these equivalent form of values fall within the application appended claims equally and limited
Scope.
As it can be seen, a kind of machine chuck power-off preventer, including guard shield 1, guard shield 22, change 3, main shaft end cap
4, main spindle box 5, travel switch box 6, travel switch 7, cover plate 8 and spacer pin 9, described guard shield 1 and guard shield 22 are solid by screw
Fixed, guard shield 22 is fixed by screws in change 3；Described main shaft end cap 4 is fixed by screws on main spindle box 5, main shaft end cap
4 are provided with spacer pin 9, are provided with arcuate groove 40 outside described change 3, change 3 by inner hole sleeve on main shaft end cap 4, spacer pin 9
It is stuck in arcuate groove 40；Described main spindle box 5 is provided with cover plate 8, and travel switch box 6 is fixed on cover plate 8, and travel switch 7 is installed
On stroke switch enclosure 6.
Further, described main shaft end cap 4 cylindrical is provided with step.
Further, described change 3 profile is for cutting circle, and its endoporus uses matched in clearance with main shaft end cap 4 step cylindrical.
Further, described guard shield 1 is further fixed on handle 20.
Concrete, because between change 3 and main shaft end cap 4 being matched in clearance, change 3 can turn downwards due to action of gravity
Dynamic, when turning to arcuate groove 40 and propping up spacer pin 9, spacer pin 9 just limits change 3 position, so that it is guaranteed that guard shield 1
Cover chuck 30.When after machine chuck 30 rotary work, when needing to change workpiece, by the handle 20 on guard shield 1 by change 3
It is rotated up, makes the other end of change 3 touch travel switch 7 and cause power-off at once, ensure that the operation of clamping workpiece
Safety.
