Abstract
A novel connecting device for a connecting rod and a ball screw rod is fixedly arranged at the lower port part of the connecting rod by using bolts through a positioning flange; a ball head screw rod is arranged in a thread hole of the connecting rod through a middle hole of the positioning flange; a ball head polished cylinder is arranged at a part, which is close to a ball head, of the ball head screw rod; and the size of the ball head polished cylinder is identical with the free size of the center of the positioning flange. The positioning flange can mandatorily enable the axis of the ball head screw rod to be concentric with the axis of the positioning flange, so that the defect that parts among threads deform and are damaged due to the fact that local parts of the threads are excessively stressed because unbalanced loading exists in the stress between the connecting rod and the ball head screw rod and the defect that the threads between the connecting rod and the ball head screw rod are not easy to adjust or damage accidents of the equipment occur due to that the parts among threads deform and are damaged are avoided.
Description
Technical field
The present invention relates to the jockey of a kind of connecting rod and spheroid screw mandrel, the jockey of particularly a kind of novel link and spheroid screw mandrel belongs to the metal forming machinery technical field.
Background technology
Connecting rod and ball screw are the critical function parts of forcing press, and they lean on both internal and external threads to cooperate transmission pressure, simultaneously by leaning on the controllability between both screw threads to realize the adjusting to forcing press operating mechanism.At present; The screw thread that in the use of reality, usually takes place between the two is difficult to regulate; Even the phenomenon that thread damage takes place takes place, and causes the main cause that this phenomenon takes place to be: connecting rod and the bindiny mechanism of ball screw directly are connected through both screw thread, and this method of attachment is not too reasonable; Because connecting rod and the ball screw transmission of pressure at work always do not carry out along both axis; So cause the stressed generation unbalance loading between the screw thread, local pressure is excessive, thereby causes deforming between screw thread even damaging.
Summary of the invention
The objective of the invention is to: the jockey that a kind of novel link and spheroid screw mandrel are provided; Overcome existing press connecting rod and ball screw owing to adopting direct thread connecting mode to exist: since connecting rod and ball screw at work the transmission of pressure always do not carry out along both axis; Cause the stressed generation unbalance loading between the screw thread easily; Local pressure is excessive, causes the defective that deforms between screw thread even damage; And connecting rod that causes therefrom and the difficult adjusting of the screw thread between the ball screw, or the accident of device damage.
Solving the technical scheme that its technical problem adopts is: the jockey of a kind of novel link and spheroid screw mandrel; It is the lower end oral area that is fixed and is installed in connecting rod with bolt by locating flange, from the mider hole of locating flange, is installed to ball screw in the screwed hole of connecting rod; In the part of ball screw near bulb, be provided with a bulb light cylinder, the size of bulb light cylinder is identical with the free size at the center of locating flange.
Beneficial effect: because locating flange can guarantee forcibly that the axle center of ball screw is concentric with the axle center of himself; So avoided between connecting rod and the ball screw because the stressed screw thread local pressure that unbalance loading caused is excessive causes: the defective that deforms between screw thread even damage; And connecting rod that causes thus and the difficult adjusting of the screw thread between the ball screw, or the defective of device damage accident.
