Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment.

[0024] See Figure 1 to Figure 6 , the steps of a method for clamping porous parts using a general-purpose vacuum platform in the present invention are as follows:

[0025] Hole 2 is made on the positioning surface of part 1, that is, the vacuum adsorption surface is opened, and the depth of hole 2 is: web thickness + milling cutter bottom tooth R + 1mm;

[0026] Use plaster 3 to fill the opening of part 1;

[0027] After the gypsum 3 is solidified, scrape off the position above the positioning to ensure that it is flush with the positioning surface;

[0028] Use tape 4 to seal the hole, the diameter of the hole should be less than 50mm; the bonding width between tape 4 and the periphery of the hole is greater than 10mm, and the bonding length in the direction of the tape length is greater than 30mm;

[0029] Clamp the part 1 to the general vacuum platform 5 for vacuum adsorption ...

Abstract

The invention discloses a method for clamping porous parts by applying a general vacuum platform. Holes are milled when reference surfaces of parts are machined; the holes are filled by using gypsum,and are sealed by using special adhesive tapes; and then, the general vacuum platform is used for clamping. An avoidance part has no need to be considered on the general vacuum platform, so that the whole part absorbing area is increased, the vacuum absorbing strength is improved, and the manufacturability of the parts is improved; an avoidance area has no need to be arranged on the vacuum platform regardless of increase or decrease of the number of the holes in the parts, so that the production cost is reduced and the part transfer period is shortened; and the method is simple and easy to operate, improves the generality of the general vacuum platform, and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to the technology of using a vacuum platform to clamp parts. Background technique [0002] In the field of CNC machining, in order to improve the stability of parts processing, special vacuum milling clamps are usually used for vacuum adsorption clamping and positioning processing technology to improve the rigidity of parts processing. For porous parts, holes of various sizes are distributed in different positions. When using a general-purpose vacuum platform for processing, it is easy to leak air, resulting in unstable processing. Contents of the invention [0003] In view of the above disadvantages, the present invention provides a method with stable processing and a vacuum platform that is not easy to leak. [0004] Technical scheme of the present invention is: [0005] A method for clamping porous parts using a general vacuum platform, comprising: [0006] S1 ...
