Description

Technical Field

[0001] The utility model relates to a turning and cutting fixture for stainless steel parts. Background Art

[0002] The bending of integral pipe parts is widely used in aerospace and civil fields. Straight pipes with different material thicknesses and inner diameters have certain specifications and can be bent through straight pipes. However, for some straight pipes with special material thicknesses and inner diameters, they need to be bent after cutting the thickness, resulting in high processing costs. Forming a half-tube from sheet metal and then welding the two parts can reduce processing costs. The processing efficiency of welding two parts requires ensuring the butt gap and groove size of the two parts, so the half-tube parts need to be evenly chamfered. In order to improve processing efficiency, a stainless steel part cutting fixture is needed to clamp the above-mentioned half-tube parts to facilitate the chamfering of the half-tube parts by the lathe. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a turning and cutting clamp for stainless steel parts.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a turning and cutting fixture for stainless steel parts, comprising:

[0005] Clamp concrete;

[0006] The invention is characterized in that: a clamping column is fixed in the middle hole on the left end face of the clamp body, an annular groove is provided on the right end face of the clamp body, a pressure block fixedly connected to the clamp body by a plurality of bolts is provided on the right side of the clamp body, and an annular protrusion matching the annular groove is provided on the left end face of the pressure block.

[0007] In the above structure, the clamping column and the clamping body are fixed by a plurality of first screws.

[0008] In the above structure, the bolts pass through the pressing block and the clamping body in sequence and are then fixed by nuts.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the stainless steel part turning fixture structure of the utility model is reasonably designed, can clamp two to four half-tube parts at one time, and can ensure the accuracy and consistency of the part turning dimensions, ensure the butt gap for subsequent welding of two parts, facilitate mechanical welding, reduce processing costs, and improve processing efficiency.
