Embodiment Construction

[0026] figure 1 It is a front view of the supporting disk of the present invention, which mainly includes blind holes 5, 6 for inserting diodes 37 for positioning, through holes 7-35 distributed in a spiral shape at equal intervals, and two holes for vertically supporting the disk. The positioning planes are the lower positioning plane 1-2 and the upper positioning plane 3-4. figure 2 It is the bottom view of the supporting disk of the present invention. image 3 is the isometric drawing of the support disc assembly.

[0027] When this supporting disc is working, it is first placed on the horizontal truss for installation. The first step is to insert 29 vertical fixing components 38 into the through holes 7-35 of the supporting disc, the vertical fixing components 38 can be rotated in this through hole to adjust the angle of installation, and the part of the vertical fixing component 38 protruding out of the disc With threads, the nuts are tightened when the final position...

Abstract

Provided is a supporting disk for a soldering tool clamp of a micro-diameter thin-walled tube of a heat exchanger. As for the main structure, the supporting disk is in a spoke wheel disk shape. The supporting disk comprises round positioning holes distributed in a spiral mode, round diode mounting holes and two positioning planes. The supporting disk is formed by carrying out cutting and drilling on a panel part. Firstly, the boundary dimension of the disk is obtained through machining, specifically, an internal ring, an external ring and a spoke wheel in the middle are included, and the axis of the disk is determined as the origin of coordinates; then the twenty-nine through holes are evenly distributed along the spiral central axis of the micro-diameter thin-walled tube in the thickness direction of the disk; the two blind holes for mounting of diodes are obtained in the thickness direction of the disk through machining; and finally, the two positioning planes are formed on the upper portion and the lower portion of the disk through cutting. According to the supporting disk, the structure is simple, manufacturability is good, structure rigidity of the integral disk can be ensured, and the structure weight can be lowered.

Description

technical field [0001] The invention relates to a supporting disc used for brazing jigs of micro-diameter thin-walled tubes of heat exchangers, which is suitable for providing precise positioning when brazing spiral micro-diameter thin-walled tubes arranged in an array, and keeping the positions fixed role. It belongs to the field of aerospace science and technology. Background technique [0002] With the continuous improvement of aero-engine power, the aero-engine heat exchanger is an important equipment for cooling and heat transfer, and its cooling effect directly affects the heat dissipation effect of the engine and its power, economy and reliability. Therefore, more and more attention has been paid to the development of efficient aero-engine heat exchangers. The heat exchanger contains a large number of dense micro-diameter thin-walled tubes, and its precise positioning in the heat exchanger not only directly affects the heat exchange efficiency of the heat exchanger,...
