Machining tool of part with multiple stepped holes and working method thereof

Abstract

The invention discloses a machining tool of a part with multiple stepped holes. The machining tool of the part with the multiple stepped holes is characterized in that the machining tool comprises a base support, side cushion blocks, middle cushion blocks, positioning blocks and clamping plates, the positioning blocks are fixed on the two perpendicular sides of the upper surface of the base support respectively, the side cushion blocks are fixed on the four sides of the upper surfaces of the base support respectively, the middle cushion bocks are fixed on the base support, the clamping plates are fixed with the base support through bolts, and screws are tightened or loosened to enable a workpiece to be clamped or released. The working method of the machining tool of the part with the multiple stepped holes comprises the steps that (1) the tool is connected and fixed with a gantry device; (2) the workpiece and the tool are clamped and pressed, and via holes corresponding to threaded holes in the cushion blocks and holes within the prebored hole range are drilled in the workpiece so that the bolts are prevented from intervening the workpiece; (3) the workpiece is connected with the middle cushion blocks with the screws, and other holes of the workpiece are machined by means of the gantry device. The machining tool of the part with the multiple stepped holes and the working method thereof have the advantages that due to the fact that the workpiece is connected with the cushion blocks through the screws, the middle of the workpiece can not protrude out during hole drilling, the flatness of the workpiece can be guaranteed, and accuracy requirements of the depths of the stepped holes are met.

Description

(1) Technical fields: [0001] The invention relates to a device for mechanical processing and its working method, a numerical control equipment processing tool and its working method, which are suitable for processing a kind of multi-step hole parts. (2) Background technology: [0002] The process before using the tooling for processing each hole of a multi-step hole workpiece is: 1) Fine milling thickness allowance. 2) Put the aluminum plate under the workpiece and press it on the workbench to drill the workpiece. 3) Install the card multiple times to grind the thickness to survive. Because the aluminum pads cannot be positioned accurately, the coordinates of the workpiece need to be calibrated before each machining. Simultaneously, the cushion block will be replaced with a new piece every time it is processed, and the waste is relatively large. Such workpieces have different external dimensions, so the original method cannot be applied to workpieces of different sizes, a...

Problems solved by technology

At the same time, the cushion block needs to be replaced with a new one every time it is processed, which is a big waste

The external dimensions of such workpieces are different, so the original method cannot be applied to workpieces of different sizes, and the versatility is poor

Therefore, there are many holes processed in this type of workpiece, and the workpiece will be deformed after processing, and the middle will bulge, which will affect the depth of the step hole, and it is difficult to ensure the flatness of the workpiece.
