Description
Technical Field
The utility model relates to a clamping mechanism, in particular to a pull-down type centering clamping mechanism.
Background
At present, most of the centering clamps in the market are of a translation type, can only play a centering role, and do not have downward grasping force. When the outer part of the blank part is irregular or rough, the force for clamping the workpiece can be greatly reduced, and an auxiliary pressing oil cylinder needs to be additionally arranged on the outer part, so that the cost is correspondingly increased.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the defects in the prior art, and provides the pull-down type centering and clamping mechanism which has the advantages that firstly, a slide block is changed into a guide column, the processing is more convenient, the downward tensioning force is provided for pulling down a clamping workpiece, the force for clamping the workpiece is correspondingly increased, and the centering effect and the clamping effect are achieved.
The technical problem of the utility model is mainly solved by the following technical scheme:
a pull-down centering and clamping mechanism comprises a base, wherein a pull disc capable of moving up and down is arranged in the bottom of the base and extends upwards into the base, guide columns capable of obliquely moving up and down are respectively arranged in the left end and the right end of the base, a clamping groove used for clamping a workpiece is formed in the upper portions of the guide columns, the pull disc pulls the guide columns to obliquely move and the guide columns move to clamp the workpiece, and the center position of the pull disc and the center position of the base are the same.
Carry out centering location through the drawing disk, drive the guide pillar through the displacement to the drawing disk and carry out the displacement, the guide pillar presss from both sides tightly gradually the work piece. The structure is simple and efficient, and the operation is flexible.
Preferably, the lower end of the guide post is fixed with the pull disc, the outer wall of the guide post is provided with a limiting groove, the side wall of the base is provided with a limiting screw for limiting the displacement of the guide post, the pull disc is pulled to displace through the linear oil cylinder, and the linear oil cylinder is positioned below the base.
The limiting screw can well limit the displacement distance of the guide post. The base is also provided with limiting screw positions at different positions to adapt to different requirements.
Preferably, the upper part of the base is provided with a centering through hole which is communicated with the pull disc, and a plug is arranged in the centering through hole.
Preferably, the side wall of the base is provided with an inner groove, and a baffle is arranged in the inner groove.
The principle is as follows: two small U-shaped grooves are formed in the guide column, two limiting screws are screwed through threaded holes in the side edge of the base and prop against the U-shaped holes in the guide column to achieve the determining effect of the angular direction, and then the lower oil cylinder can achieve the functions of downward pulling and upward lifting of the guide column through connection of the pull disc.
The utility model provides a pull-down type centering and clamping mechanism which is high in structure compactness, high in centering precision and excellent in clamping effect.
