Abstract
The utility model relates to a locking device of a workbench. The machining principle of a gun-drill machine tool is relatively special. When an asymmetrical blade is cut, the reciprocating torque is very high and is periodic. If a servo motor is adopted to lock by self, a small hole can be machined, but the workbench is seriously vibrated when the hole with relatively large aperture is machined, and the phenomena of blade breaking, aperture inaccuracy, poor roughness of the hole and the like are probably caused. The locking device of the workbench comprises the workbench, a motor and a ball screw, wherein the left end of the ball screw is connected with the servo motor; the right end of the ball screw is connected with an electromagnetic clutch; and the electromagnetic clutch is connected with the workbench through a supporting base. The electromagnetic clutch is arranged in the device, so that after the workbench is moved to be in place, the electromagnetic clutch can be matched with the servo motor to lock the ball screw, so the workbench is locked, and is reliable and fixed, reliable machining on large aperture is satisfied, and the phenomena of blade breaking and poor roughness of the hole are prevented.
Description
Technical field
The utility model relates to the deep hole machining technical field, relates to a kind of locking device of workbench.
Background technology
In the deep hole machining, workbench needs laterally mobile in a lot of occasions, and this function realizes by servomotor usually, after movable workbench arrives accurate position, need workbench is locked, so that deep hole machining is reliable and stable, the locking of workbench usually, be to rely on that servomotor self is locked just can be realized, but because the process principle of drill gun lathe is more special, when carrying out asymmetric blade cutting, back and forth moment is very big, and be periodic, if adopt servomotor self locking, during the processing aperture can, if when the aperture is big slightly, workbench is just shaken very severe, might cause breaking, aperture size is inaccurate, phenomenons such as hole roughness difference.
Summary of the invention
The purpose of this utility model provides a kind of table latch device that prevents the workbench shake.
The technical scheme that the utility model adopts is, a kind of locking device of workbench, comprise workbench, motor and ball-screw, the left end of described ball-screw is connected with servomotor, it is characterized in that: the right-hand member of described ball-screw is connected with electromagnetic clutch, and described electromagnetic clutch is connected with workbench by bearing.
The inside of described electromagnetic clutch is provided with friction plate, and described friction plate is connected with the right-hand member of ball-screw.
Compared with prior art, the beneficial effects of the utility model are: be provided with electromagnetic clutch in this device, after movable workbench puts in place, electromagnetic clutch can cooperate servomotor locking ball-screw, like this will be with table latch, make the workbench secure fixation, satisfied wide-aperture reliable processing.Avoid causing phenomenons such as breaking, aperture size are inaccurate, hole roughness difference.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1. workbench, 2. servomotor, 3. ball-screw, 4. electromagnetic clutch.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, a kind of locking device of workbench, comprise workbench 1, servomotor 2 and ball-screw 3, the left end of described ball-screw 3 is connected with servomotor 2, it is characterized in that: the right-hand member of described ball-screw 3 is connected with electromagnetic clutch 4, described electromagnetic clutch 4 is connected with workbench 1 by bearing, and the inside of described electromagnetic clutch 4 is provided with friction plate, and described friction plate is connected with the right-hand member of ball-screw 3.
Operation principle of the present utility model is: after movable workbench puts in place, servomotor 2 locks self, the inner magnetic field absorption friction plate that produces in electromagnetic clutch 4 energising backs, friction plate is connected with the right-hand member of ball-screw 3, so just that leading screw is locked, thus reach the effect that locks workbench with servomotor 2.
In sum, the electromagnetic clutch of described device can cooperate servomotor locking ball-screw, table latch will be made the workbench secure fixation like this, has satisfied wide-aperture reliable processing.
