Background

In the current machining system, the machining of single parts and small-batch parts still adopts manual compaction. The problems that the operation is complex, the technical requirement on workers is high, the time is wasted and the like exist in the use of a common manual pressing plate pressing mechanism.

SUMMERY OF THE UTILITY MODEL

The utility model mainly solves the defects in the prior art, and provides a manual rotating pressing mechanism which can rotate the top screw clockwise, the pressing plate can automatically rotate back to the right position and then press down, the top screw is screwed anticlockwise, the pressing plate can automatically lift and rotate for a certain angle, and parts can be conveniently mounted and taken.

The technical problem of the utility model is mainly solved by the following technical scheme:

the utility model provides a manual rotatory hold-down mechanism, includes the base, the base in be equipped with can spacing pivoted rotation axis and rotation axis in be equipped with elastic connection's compressing tightly the pole, the downward elastic displacement of rotation axis drive compress tightly the pole and carry out the downward displacement and be rotatory. The structure is small, and the operation in a narrow space is very convenient, and meanwhile, the stability is good. The rotation stroke of the rotating shaft was 7 mm.

Preferably, the outer wall of the rotating shaft is provided with a plurality of spiral grooves, the inner wall of the base is provided with a semi-embedded steel ball, the rotating shaft rotates and displaces downwards along the steel ball through the spiral grooves, and the lower end of the rotating shaft is sleeved with a spring. The inner wall of base is equipped with the nest hole that equals quantity with the helicla flute, and the steel ball is established in the nest hole, and the quantity in nest hole is 3, and 3 nest holes are evenly distributed. The diameter of the lower end of the rotating shaft is reduced, and the spring is sleeved in the lower end of the rotating shaft.

Preferably, the bottom of the base is provided with a cushion block, the bottom of the spring is elastically connected with the cushion block, and the pressing rod penetrates through the cushion block and extends downwards.

Preferably, the upper end of the pressing rod extends upwards to form a rotating shaft, a pressing plate is sleeved at the upper end of the pressing rod, a plane bearing is arranged between the pressing plate and the pressing rod, the pressing plate returns through the plane bearing, and the bottom of the pressing plate is arranged at the upper part of the rotating shaft.

Preferably, the rotating shaft and the base are sealed through a dustproof sealing ring, and the dustproof sealing ring is half embedded into the base.

Preferably, the bottom of the pressing rod is provided with a hexagon socket head cap screw.

The principle is as follows: three nest holes are processed on the wall of the inner hole of the base, three steel balls are arranged in the nest holes, the steel balls slide in a matched mode with the spiral groove in the rotating shaft, when the screw is screwed downwards, the rotating shaft moves along the angle and the direction of the spiral groove, when the screw is screwed upwards, the spring below the rotating shaft jacks the rotating shaft downwards, and the rotating shaft moves upwards along the spiral groove.

The utility model provides a manual rotating pressing mechanism which is high in structure compactness and convenient to operate.
