Problems solved by technology

[0004] The invention aims at the deficiency that the parallelism of the upper and lower pressure heads of the diffusion welding machine in the prior art is difficult to adjust, and provides a parallelism self-adaptive pressure head of the diffusion welding machine, which can solve the problem that the parallelism of the upper and lower pressure heads of the diffusion welding machine is difficult to adjust The bottleneck of the welding process that causes a low welding pass rate can eliminate the influence of the non-parallelism of the upper and lower pressure heads of the diffusion welding machine on the uniformity of the welding pressure, and save the tedious operation process of frequently adjusting the parallelism

Embodiment 1

[0018] Embodiment 1: With reference to Fig. 1. The parallelism adaptive pressure head of the diffusion welding machine of the present invention includes a lower pressure rod 3, a lower pressure head 4, an upper pressure head 6 and an upper pressure rod 8, and also includes a base 1, steel balls 2 and ceramic balls 7. 1. The top of the cylinder has a hemispherical concave surface matching with the steel ball 2. The steel ball 2 is placed in the hemispherical concave surface on the top of the cylinder of the base 1. The lower end of the lower pressure rod 3 is ground and connected with the lower pressure head 4. The pressure rod hole below the furnace 9 is positioned and placed on the top of the steel ball 2; a boss is designed on the top of the upper pressure head 6, and a hemispherical concave surface matched with the ceramic ball 7 is arranged on the convex platform, and the ceramic ball 7 is placed in the hemispherical concave surface. The lower end of the upper pressing rod...

Embodiment 2

[0021] Embodiment 2: The parallelism self-adaptive pressure head structure of the diffusion welding machine is the same as the embodiment 1, the diameter of the base 1 cylinder is 120 mm, and the radius of the hemispherical concave surface at the top is 40 mm. The surface of the steel ball 2 is nitrided and hardened, and the surface of the steel ball 2 is in free contact with the lower end surface of the lower pressing rod 3; the radius of the steel ball 2 is 40mm. The radius of the hemispherical concave surface on the top boss of the upper pressing head 6 is 15mm, and the surface of the ceramic ball 7 is in free contact with the lower end of the upper pressing rod 8; the radius of the ceramic ball 7 is 15mm.

Embodiment 3

[0022] Embodiment 3: The adaptive adjustment method of the parallelism adaptive pressure head of the diffusion welding machine is the following steps:

[0023] (1) Embedding the steel ball 2 on the base 1, after fixing the lower pressure head 4 and the lower pressure rod 3, place the lower end plane of the lower pressure rod 3 on the top of the steel ball 2;

[0024] (2) Embedding a ceramic ball 7 on the upper end surface of the upper pressing head 6;

[0025] (3) When welding each time, the workpiece 5 is placed on the lower indenter 4, the upper indenter 6 is placed on the workpiece 5, and the position is adjusted;

[0026] (4) Move the upper pressing rod 8 to the top of the ceramic ball 7 on the upper end surface of the upper pressing head 6, apply welding pressure, make the upper and lower pressing heads fit the upper and lower surfaces of the workpiece, and complete the self-adaptive adjustment.

Abstract

A parallelism-adaptive press head of diffusion weld is composed of base, lower press rod with flat lower end, lower press head, upper press rod with flat lower end, upper press head, steel ball arranged between base and lower press rod, and ceramic ball arranged between upper press head and upper press rod. Its adaptive regulation method is also disclosed.

Description

technical field [0001] The invention relates to a parallelism adaptive pressure head of a diffusion welding machine, and also relates to an adaptive adjustment method of the pressure head of the diffusion welding machine. Background technique [0002] Diffusion welding is a method of closely bonding the surfaces of two metal or ceramic workpieces to be welded, and keeping them under a certain temperature and pressure for a period of time in a vacuum or protective atmosphere, so that the atoms between the contact surfaces diffuse each other to complete the connection. Welding method. [0003] In the design of the diffusion welding machine, the welding pressure is generally transmitted to the contact surface of the weldment through a pair of upper and lower pressure heads whose end faces are parallel. Therefore, the parallelism of the upper and lower pressure heads will affect the uniformity of pressure distribution on the contact surface and the deformation of the workpiece ...
