A banded thin pieces parts carrier fixture structure and how to use

Abstract

The invention discloses a turning clamp structure for sheet parts with turbulence, comprising a clamping rod, a support plate protruding horizontally at the lower end of one side of the clamping rod, and a positioning bushing is arranged inside the clamping rod along its length direction A fixing hole, a positioning bush is fixed in the fixing hole of the positioning bush, a positioning mandrel penetration hole is arranged inside the positioning bush, and a pressing block is placed on the other end of the support plate, and one end of the pressing block facing the positioning bush is provided with Positioning mandrel fixing hole, the tail of the positioning mandrel is fixed in the positioning mandrel fixing hole, after the shaft body penetrates several overlapping sheet parts in the same direction, the head end extends into the positioning mandrel penetration hole, where the positioning The end face of the bushing, the pressing block and the sheet part contacting is the same structure as the contact surface of the sheet part. The fixture structure solves the problems of difficult positioning, difficult orientation, difficult clamping, and difficult pressing when machining thin sheet parts with turbulence.

Description

technical field [0001] The invention relates to a lathe part turning fixture structure and a use method thereof, in particular to a sheet part lathe work fixture structure with disturbance and a use method thereof. Background technique [0002] Machine tool fixture design is an important part of process equipment design. In the entire machining process, in addition to clamping and fixing the machined parts, the fixtures are also required to ensure the shape and position tolerance accuracy of the machined parts and improve the machining productivity. [0003] In the field of mechanical production and processing, it is often necessary to process various flake parts, which are small in size, thin in thickness, and have poor rigidity. The processing quality, especially the sheet parts with turbulence, how to quickly and efficiently clamp them to various processing equipment to process qualified products is an urgent problem to be solved. In our company's products, there is a sp...

AI Technical Summary

Problems solved by technology

The reasons are: (1) The product is disturbed, the positioning surface is uneven, and positioning is difficult

(2) The product is a special-shaped piece, and it is difficult to orientate

(3) The thickness of the product is only 1.5mm and it is easy to deform, so it is difficult to clamp

[0006] processing Outer circle size to When it comes to dimensioning, the conventional method is: (1) Use the clamping method of three-jaw supporting the inner hole of the part to process the outer circle, but the existing situation is that the inner hole is too small, and there is no way to support the inner hole Dimensions to process the outer circle, can not be achieved

(2) A general three-jaw chuck is used to clamp the outer circle for processing, but the wall thickness of the part is too thin, its thickness is only 1.5mm and there is a disturbance, the part has no clamping part, and it is easy to deform during the turning process, which cannot be realized Processing of clamping outer circle
