Abstract
The invention provides a novel device for connecting a press connecting rod and a ball screw rod. A positioning flange is fixedly arranged on the lower port of the connecting rod through a bolt and a fastening bolt; during installation, the axle center of an unthreaded hole of the positioning flange is concentric with the axle center of the connecting rod and fixed to a machine body; the ball joint screw rod is arranged in a connecting rod threaded hole from the middle hole of the positioning flange; during installation of the positioning flange, the axis of the unthreaded hole of the flange is concentric with the axis of a threaded hole on the connecting rod; the diameter of a central unthreaded hole in a guide flange is slightly greater than the large diameter of an internal screw thread on the connecting rod or the large diameter of an external screw thread on the ball joint screw rod; a part, which is close to a ball joint, of the ball joint screw rod is made into a section of ball joint cylinder; the free size of the outer diameter of the ball joint cylinder is the same as that of the central unthreaded hole of the positioning flange; and minor clearance fit is formed in the aspect of tolerance.
Description
Technical field
The present invention relates to the jockey of a kind of press connecting rod and spheroid screw mandrel, the jockey of particularly a kind of novel press machine connection rod and ball screw rod.Belong to the metal forming machinery technical field.
Background technology
Connecting rod and ball screw are the critical function parts of forcing press, and they transmit pressure by the cooperation of both internal and external threads, simultaneously by the adjusting that realizes by the controllability between both screw threads forcing press operating mechanism.At present, the screw thread that usually takes place in the use of reality between the two is difficult to regulate, even the phenomenon that thread damage takes place takes place, cause the main cause that this phenomenon takes place to be: connecting rod and the bindiny mechanism of ball screw directly are connected by both screw thread, this method of attachment is not too reasonable, because connecting rod and the ball screw transmission of pressure at work are not always to 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 press machine connection rod and ball screw rod 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 be not always to 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: at the lower end of connecting rod oral area, one location flange is set, the intermediate fabrication light hole of locating flange, the unthreaded hole axis that guarantees flange simultaneously when locating flange is installed is concentric with the silk axially bored line on the connecting rod, simultaneously in above-mentioned guide flange, the diameter of its center unthreaded hole is a bit larger tham the big footpath d2 of the internal thread on the connecting rod or the externally threaded big warp above the ball screw to d2, in the part of ball screw near bulb, make one section light cylinder, the external diameter free size of its light cylinder is identical with the free size of the center unthreaded hole of locating flange, and both form small matched in clearance on tolerance.
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 accident of device damage.
