Problems solved by technology

However, when the screw nut transmission pair is working, the screw nut will move linearly along the axial direction of the screw screw. If the traditional fixed support mechanism is used to support the screw screw, it is bound to encounter the situation that the screw nut cannot move.
That is to say, the traditional fixed support mechanism cannot be applied to the support of longer lead screws

Abstract

The invention discloses a long-stroke lead screw movable auxiliary supporting mechanism. The mechanism comprises a sliding seat, a lead screw supporting sleeve is fixedly connected to the upper portion of the sliding seat, and meanwhile, the side face of the lead screw supporting sleeve is further provided with a connection unhooking mechanism. The sliding seat is slidably connected to a sliding rail, the connection unhooking mechanism is rotationally connected to the lead screw supporting sleeve through a rotating shaft, rollers are arranged at the bottom of the connection unhooking mechanism, a connecting hook is arranged at one end of the top of the connection unhooking mechanism, and the other end of the top of the connection unhooking mechanism is provided with a limiting part. A connecting hook inclined surface is arranged on one side of the connecting hook, the rotating shaft is located between the connecting hook and the limiting part, a limiting block matched with the limitingpart is arranged on the lead screw supporting sleeve, a torsion spring is further arranged on the rotating shaft, and a spring wire of the torsion spring is in contact with a protruding part arrangedon the connection unhooking mechanism. The supporting mechanism further comprises driving blocks, the driving blocks are arranged on the side face of the sliding rail and matched with the rollers, and driving inclined surfaces are arranged at the two ends of each driving block.

Description

technical field [0001] The invention relates to a support mechanism, in particular to a long-stroke lead screw movable auxiliary support mechanism. Background technique [0002] Screw and screw nut is a transmission mechanism that can convert torque into linear motion. This transmission pair has been widely used in many places in industrial production activities. For some relatively long screw, due to the rigidity of the material, it is inevitable to encounter the problem of deflection (that is, the part lacking support will appear to fall and deform), generally speaking, it needs to be far away from the support point. An auxiliary support mechanism is added at the position (that is, the suspended position) to prevent the occurrence of the above-mentioned problems. However, when the screw nut transmission pair is working, the screw nut will move linearly along the axial direction of the screw screw. If the traditional fixed support mechanism is used to support the screw scr...
