Problems solved by technology
[0003] The purpose of the present invention is to provide a novel connection device for a press connecting rod and a ball screw, which overcomes the existing problem of the existing press connecting rod and ball screw due to the use of a direct threaded connection: the connecting rod and the ball screw The pressure transmission of the ball screw during work is not always carried out along the axes of the two, which may easily lead to unbalanced loading of the force between the threads, excessive local force, and deformation or even damage between the threads; and The thread between the connecting rod and the ball screw caused by this is not easy to adjust, or the accident of equipment damage

Embodiment Construction
[0008] Fix the positioning flange (3) to the lower port of the connecting rod (1) with bolts (4), and install the ball screw (2) to the connecting rod through the middle hole of the positioning flange (3) In the threaded hole of (1); in the part of the ball screw rod (2) close to the ball head a, a ball head light cylinder (5) is made, and the size d1 of the ball head light cylinder (5) is consistent with the positioning flange (3) The free dimensions of the center b of are the same.

The invention discloses a connecting device of a novel press connecting rod and a sphere lead screw. A locating flange is fixedly installed on the lower port part of the connecting rod by bolts; a ball lead screw is installed in the tapped hole of the connecting rod from the central hole of the locating flange; the ball lead screw is close to the part of the ball to form a ball light cylinder; and the size of the ball light cylinder is same with the free size of the center of the locating flange. Because the locating flange can forcefully ensure that the axle center of the ball lead screw is concentric with the axle center of the locating flange, the defect that screw thread deforms even damages because the local stress of the screw thread is overlarge due to stressed unbalance loading between the connecting rod and the ball lead screw can be avoided, and the defect that the lead screw between the connecting rod and the lead screw is not easy to regulate or equipment is damaged can be solved.
Description
technical field [0001] The invention relates to a connecting device for a press connecting rod and a ball screw, in particular to a novel connecting device for a press connecting rod and a ball screw, belonging to the technical field of forging machinery. Background technique [0002] The connecting rod and the ball screw are important functional parts of the press. They transmit pressure by the cooperation of the internal and external threads of the two, and at the same time, the adjustment of the working mechanism of the press is realized by the adjustability between the two threads. At present, in the actual use process, it often happens that the thread between the two is difficult to adjust, and even the thread is damaged. The main reason for this phenomenon is that the connection mechanism between the connecting rod and the ball screw is through two The thread of the other is directly connected, this connection method is not reasonable, because the pressure transmission...
