Abstract
The utility model discloses a movable blocking device of a hydraulic driving mechanism. The hydraulic driving mechanism comprises an oil cylinder and a moving mechanism driven by the oil cylinder. The blocking device comprises an idler wheel and a blocking part which is fixed on one side face of a machine frame and used for limiting a moving terminal of the moving mechanism in the first dimensional direction. The idler wheel is arranged on one side face of the moving mechanism, and is opposite to the blocking part surface. Due to the fact that the blocking part perpendicular to the first dimensional moving direction is arranged on the machine frame and used for limiting the moving terminal of the moving mechanism in the first dimensional moving direction, the moving mechanism can be positioned in the first dimensional direction. The idler wheel is arranged on the moving mechanism, the idler wheel moves attaching the blocking part surface tightly, and therefore the second dimensional moving direction in which the moving mechanism moves is perpendicular to the first dimensional moving direction in which the moving mechanism moves.
Description
Technical field
The utility model relates to the dead blocking means of a kind of mechanized equipment, particularly needs to carry out the hydraulically powered movable dead blocking means that is subjected to of two dimensional motion.
Background technique
For making to be subjected to the accurate off-position of hydraulically powered winding machine, be generally to realize by the mode that dead gear is set.This mode is for one dimensional motion mechanism, and its off-position degree of accuracy and steady status, be enough to meet technological requirement.But, when two dimensional motion need be done by mechanism, for example, after mechanism moves along a straight line and puts in place, also need to do appropriate the moving up and down perpendicular to one dimensional motion, the damned gear utmost point is unfavorable for the two dimensional motion of mechanism.Usually, have to cancel dead gear and with oil cylinder, take blame for others to limit the terminal of one dimensional motion, the drawback of such caving-in bash is, 1, oil cylinder top structure rapid wear; 2, two dimensional motion is difficult to perpendicular to one dimensional motion.These 2 drawbacks shorten the working life of associated components, and make the track of two dimensional motion be difficult to strictly meet technological requirement.
As shown in Figure 1, be a kind of equipment special of high efficiency manufacture casting sand mould.The action of its main technique sequentially as after, that is:
1. the indexing mechanism transposition is 120 °, drive a sand frame standard be parked in Vertical Cylinders with template top;
2. cross cylinder moves back, and send the sand in sand hopper to leak into the sand frame along pushing away under sand hopper;
3. cross cylinder advances, and the lower limb that pushes away sand hopper is bulldozed the sand of accumulation, makes cloth sand even thickness on template, and after cross cylinder advanced and puts in place, the seaming chuck standard that it drives was parked in sand frame top;
4. the piston rod of Vertical Cylinders stretches out, and template and sand frame are headed on up, and when the sand frame upwards withstands the lower plane of seaming chuck and makes seaming chuck also up until withstand the frame strut rail together, Vertical Cylinders continues upwards to exert pressure, and the sand in the sand frame is compacted moulding;
5. Vertical Cylinders band moving pattern plate is descending, and it is motionless that sand frame and seaming chuck are still withstood on top by other ad hoc jacking mechanism, thereby make template with sand mold, separate (demoulding);
6., after the demoulding completes, roll back station after with the sand frame of sand mold, surpassing the action range of jacking mechanism with the descending displacement of Vertical Cylinders;
7. three position mechanism 1 transposition is 120 °, produces with the sand frame of sand mold, takes away for operator or mechanism hand, and meanwhile, existing empty sand frame standard is stopped at pressing position, for compacting is next time got ready.
In above-mentioned manufacturing process, seaming chuck level before this advances and arrives sand frame top, again under the power of the top of Vertical Cylinders, is headed on up until frame strut rail by the sand frame while suppressing subsequently, and seaming chuck need to be made two dimensional motion.For one dimensional motion mechanism, for making to be subjected to the accurate off-position of hydraulically powered winding machine, be generally to realize by the mode that dead gear is set.This mode its off-position degree of accuracy and steady status, be enough to meet technological requirement.But, when two dimensional motion need be done by mechanism, after mechanism moves along a straight line and puts in place, also need to do appropriate the moving up and down perpendicular to one dimensional motion, the damned gear utmost point is unfavorable for the two dimensional motion of mechanism.Usually, the location that have to cancel dead gear and take blame for others to realize one dimensional motion with oil cylinder, the drawback of doing like this is: one, because the stroke of oil cylinder is used up, oil cylinder top structure rapid wear, seaming chuck is up rear because without the fuel distance position, bouncing back, the i.e. track of two dimensional motion to be not orthogonal to the first maintenance and operation moving, the uniformity of this rear sand hardness that is unfavorable for guaranteeing being shaped; Two, during the demoulding, when template downwards first from moment of sand mold, the total weight of seaming chuck and sand frame (containing sand mold) is born by jacking mechanism, this is for jacking mechanism, load is laid particular stress on, in case the deficiency of jacking power this moment, it is moving that downward forward wink namely can occur for seaming chuck and sand frame, make sand mold and ring mould bump or wipe extension, sand mold must be impaired.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of movable dead blocking means of hydraulic drive mechanism, can overcome above-mentioned deficiency.
For achieving the above object, the utility model provides following technological scheme:
A kind of movable dead blocking means of hydraulic drive mechanism, described hydraulic drive mechanism comprises oil cylinder and by the motion of hydraulic oil cylinder driving, described dead blocking means comprises pulley and dead gear, described dead gear is fixed on a side of frame, for the exercise end of constrained motion mechanism in the first dimension direction, side of described motion is provided with roller, and roller is relative with dead block face.
Further, described motion is connected with the piston rod of cross cylinder by twisted axis mechanism.
Further, described cross cylinder is arranged on crossbeam by twisted axis mechanism.
The beneficial effects of the utility model are: by dead gear is set on frame, for constrained motion mechanism exercise end in the horizontal direction, realized the location of motion the first dimension direction, roller is set on motion, has realized that the motion two dimensional motion is vertical with the one dimensional motion direction.
