Method and device for compressing numerical control machining built-in parts

Abstract

The invention discloses an embedded type part compressing method which can fasten a part below a part supporting plane and does not affect the normal cutting process at the same time and a compressing apparatus. The compressing apparatus includes a clamp platform for loading and clamping the part and a compressing liner bushing; the clamp platform is provided with a counter bore used for mounting the compressing liner bushing, the compressing liner bushing is a cup-shaped liner bushing with an outer edge, the height of the liner bushing is just suitable for the outer edge to compress a step in a step hole of the part in the counter bore of the clamp platform, and the bottom of the liner bushing is fixed in the counter bore of the clamp platform by a connecting piece. The invention has the advantage that a compressing clamp does not affect the continuity and safety of numerical control cutting.

Description

technical field [0001] The invention relates to a part clamping and fastening technology for mechanical numerical control machining, in particular to a method and device for pressing an embedded part. Background technique [0002] In the process of CNC machining, the clamping technology of parts is very critical, and the way of clamping and fastening parts directly affects the processing method, processing efficiency and quality. In the process of CNC machining, the commonly used clamping and fastening methods are: platen fastening method, screw direct compression method, vacuum adsorption fastening method, hydraulic clamping method, etc. Each fastening method has its own advantages and disadvantages. scope of application. [0003] For some parts with relatively large structural dimensions, it is often necessary to use some structural features of the part to increase the compression point in the middle of the part to ensure the reliability of the compression. The tradition...

Problems solved by technology

[0004] Set screws in the structural gaps of parts (such as holes, gaps, etc.) to directly compress the parts - the disadvantage is that when the tool is processed to these parts, the screws must be removed to reduce the processing efficiency, and at the same time, the existing compression in the process of high-speed automatic processing The tight method is easy to cause the collision between the tool and the screw and damage the tool

[0005] Adding an extra bench to hold down the part - the downside is increased stock size, increased cost, additional work to remove the bench, and surface steps

[0006] Use the pressure plate to directly compress the parts - it is necessary to switch the position of the pressure plate during the processing, which is easy to cause the risk of collision
