Description

Special-shaped part clamp

Technical Field

The utility model relates to the technical field of part production and processing, in particular to a special-shaped part clamp.

Background

At present, along with the rapid development of industry, more and more special-shaped parts are put into production practice, the structure is complex, the processing requirements relative to standard parts are greatly different, and when the special-shaped parts are processed, effective clamping of the special-shaped parts is difficult to realize if universal clamping parts are used, sliding is easy to occur or the clamping force is too high, so that the special-shaped parts are required to be clamped by using a special-shaped part clamp;

the publication No. CN209157751U discloses a special-shaped part clamp, which comprises a clamp workbench and a clamping part. The utility model provides a special-shaped part clamp, which aims at special-shaped parts, realizes positioning through the matching of a clamping column and a positioning column and prevents the parts from sliding in the processing process; the clamping of the part is realized by arranging the locking bolt and the positioning bolt, and meanwhile, the part is prevented from being excessively clamped to damage the structure, so that the clamping protection is realized;

if this kind of special-shaped part anchor clamps can have two problems when using in the comparison document, one is that it is spacing in advance through the stop bolt, but stop bolt is spacing the back, it just is difficult to reach necessary clamping force when shifting down to go up the grip block, lead to its clamping force bad control, and go up the fixed position of grip block in, the clamping position of part is in the side, this can lead to last grip block to the uneven dynamics of pushing down of part when the centre gripping, lead to the centre gripping not stable enough, even can appear the condition that the grip block inclines when the centre gripping appears, the centre gripping effect to special-shaped part has been reduced, and secondly it carries out spacingly to the part through the reference column, but the position of reference column is unadjustable, this just means that this anchor clamps only makes this kind of special-shaped part that is applicable to specific size, and then can make the application range of this anchor clamps less, the practicality is lower, therefore we propose a special-shaped part anchor clamps.
