Stepless latching mechanism for press slider

Abstract

The invention discloses a stepless latching mechanism for a press slider and belongs to the field of press slider locking devices. The stepless latching mechanism can lock any portion of a latching rod to achieve stepless self-locking of the press slider. The stepless latching mechanism for the press slider comprises a shell, wherein the latching rod used for being connected with the press slider is arranged in the shell, at least two clamping blocks are arranged on the periphery of the latching rod at intervals, wedge blocks located on the outer sides of the at least two clamping blocks and extrusion pieces controlling the corresponding wedge blocks to move in an axial direction of the latching rod are arranged in the shell, and the wedge blocks control the at least two clamping blocks to clamp or loosen the latching rod when sliding in the axial direction of the latching rod. For the stepless latching mechanism, the wedge blocks are controlled to ascend and descend by controlling ascending and descending of the extrusion pieces, and stepless self-locking of the press slider is achieved.

Description

【Technical field】 [0001] The invention relates to the field of locking devices for press sliders, in particular to a stepless locking mechanism for press sliders. 【Background technique】 [0002] The slider on the hydraulic machine is generally locked by the upper limit lock, the side has a step lock, and the lower part of the slider is manually supported. The upper limit lock can only be locked when the slider is moved to the upper limit, leaving the upper limit. Unable to lock, step-by-step locking requires the locking position to be fixed, and requires a micro-return of the slider when unlocking, which makes the electrical control program more complicated, and it is easy to cause the danger of the slider going down and hitting the locking mechanism in the event of an electrical failure. It has a safety function at a specific position, which is inconvenient to operate and affects production efficiency. The manual support rod is the simplest and original safety device. Its s...

[0002] The slider on the hydraulic machine is generally locked by the upper limit lock, the side has a step lock, and the lower part of the slider is manually supported. The upper limit lock can only be locked when the slider is moved to the upper limit, leaving the upper limit. Unable to lock, step-by-step locking requires the locking position to be fixed, and requires a micro-return of the slider when unlocking, which makes the electrical control program more complicated, and it is easy to cause the danger of the slider going down and hitting the locking mechanism in the event of an electrical failure. It has a safety function at a specific position, which is inconvenient to operate and affects production efficiency. The manual support rod is the simplest and original safety device, and its swing or insertion into the lower part of the slider depends entirely on manual control, which is less safe.
