specific Embodiment approach 1

[0015] Specific implementation mode 1: In this implementation mode, the bonding type processing method of the diversion core and mandrel is carried out according to the following steps:

[0016] 1. Milling the mandrel of the diversion core into a cuboid;

[0017] 2. Milling the upper curved surface of the mandrel of the diversion core, and then milling the empty grooves on both sides, and processing a Φ6 positioning pin hole at both ends of the mandrel of the diversion core;

[0018] 3. Special fixture for processing: according to the size of the upper curved surface of the diversion core shaft, process the concave surface that is closely matched with it, and then mill the empty knife grooves on both sides of the fixture and the Φ6 positioning pin holes at both ends, and after milling in step 2 The mandrel of the diversion core matches;

[0019] 4. Position and assemble the mandrel of the diversion core and the fixture through two Ф6 cylindrical pins, and use glue to bond the...

specific Embodiment approach 2

[0023] Embodiment 2: This embodiment is different from Embodiment 1 in that: the glue described in Step 4 is G39 glue. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0024] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that: the bonding time in Step 5 is 1-1.5 hours. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a sticky processing method for a diversion core mandrel, and relates to a processing method for a diversion core mandrel, aiming at solving a problem of a current diversion core mandrel which, because of lack of a processing benchmark and a locating plane, fails to locate when processing a profile curve to result in failure in processing. The method comprises steps of I. milling the diversion core mandrel into a rectangle; II. milling a curve on the upper part of the diversion core mandrel, and milling clearance grooves on two sides; processing a phi6 locating pin hole at each of two ends of the diversion core mandrel respectively; III. processing a special clamp; IV. locating and assembling the diversion core mandrel and the clamp through two phi6 cylindrical pins; integrally sticking the diversion core mandrel and the clamp through glue water; V. after sticking, milling to obtain a prospective processed diversion core mandrel; and VI. separating the diversion core mandrel from the clamp through a heating way, thus finishing processing finally. The processing method disclosed by the invention is used for processing the diversion core mandrel.

Description

technical field [0001] The invention relates to a method for processing a mandrel shaft of a guide core. Background technique [0002] The mandrel of the guide core is a mold used to manufacture important parts of the gas compressor unit. Its shape is as follows: figure 1 shown. Since the mandrel of the diversion core is an overall variable cross-section profile, the width is 18mm, the maximum thickness is 6mm, the minimum thickness is only 3mm, and the length is 160mm, the workpiece is very thin and long, and it is an integral profile surface, which requires precision Within 0.02mm. Its special shape brings difficulty to processing. Since there is no processing datum and positioning plane, it cannot be positioned when processing the curved surface of the shape, even if a five-axis CNC machine tool is used, it cannot be processed. Contents of the invention [0003] The present invention aims to solve the problem that the mandrel shaft of the current guide core cannot be...
