Problems solved by technology

At present, the locking method of the screw rod and the connecting rod is mainly to lock or loosen the screw rod by adjusting the locking block arranged on one side of the screw hole of the connecting rod of the press, because the locking block is pressed from one side of the screw rod. Tighten the screw rod so that one side of the screw rod fits closely with the other side of the connecting rod for locking. Therefore, the contact area of ​​the internal and external threads along the circumference of the connecting rod and the screw rod is different, so when working, the side of the thread The load distribution on the shaft is not uniform, so that the threads of the screw rod and the connecting rod are easily damaged. At the same time, because the locking block and the connecting rod are paired first and then processed in pairs, the interchangeability is also poor.

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] The outer locking device (3) and the connecting rod (1) are fixed to one end of the connecting rod (1) through the internal and external threads, and the middle part of the inner locking device (4) and the outer locking device (3) is processed with the connecting rod (1) ) in the middle part of the internal thread of the same specification is composed of a fixing plate (2), an upper screw mandrel (5), a lower screw mandrel (7) and a pressing plate (6) and is fixed with screws, combined with a lower screw mandrel fixing plate (8) and The upper screw fixing plate (9) forms an integral locking body (10), and the inner thread of the locking device (4) can be screwed into the inner thread of the connecting rod (1), so that the inner lock can be loosened. The tightening device (4) can adjust the upper screw mandrel (5) and the lower screw mandrel (7), and tightening t...

Abstract

The invention discloses a novel press screw rod locking mechanism. An outer locking device and a connecting rod are fixed with one end of the connecting rod through internal and external threads; internal threads with the same specification as the middle part of the connecting rod are formed on the middle parts of an inner locking device and the outer locking device; a fixing plate, an upper screw rod, a lower screw rod and a pressing plate assembly are fixed by screws; an integral locking body is formed by combining a lower screw rod fixing plate and an upper screw rod fixing plate, so that the internal threads of the locking device can be screwed in, and the internal threads of the connecting rod can be screwed in. Therefore, the upper screw rod and the lower screw rod can be adjusted by unscrewing the inner locking device, and the aim of locking the screw rod by screwing the inner locking device is fulfilled.

Description

technical field [0001] The invention relates to a screw rod locking mechanism of a press, in particular to a novel screw rod locking mechanism of a press. The utility model belongs to the technical field of screw rod locking mechanisms of presses. Background technique [0002] At present, in the connecting rod mechanism of presses at home and abroad, the screw rod connecting the slider and the connecting rod plays the role of adjusting the sealing height of the press and transmitting pressure. Therefore, the locking degree of the screw rod and connecting rod and other technologies The requirements are higher. At present, the locking method of the screw rod and the connecting rod is mainly to lock or loosen the screw rod by adjusting the locking block arranged on one side of the screw hole of the connecting rod of the press, because the locking block is pressed from one side of the screw rod. Tighten the screw rod so that one side of the screw rod fits closely with the othe...
