Problems solved by technology

If a deflection yoke is used to change the direction of the electron beam movement to avoid the outer circle of the combined teeth and avoid interference, the electron beam deflection coil is required. Due to the current domestic manufacturing technology of the electron beam deflection coil, there is a slight deficiency, and the product is in use. The stability of medium deflection angle control is not good, the precision is not high, and the quality requirements of the product cannot be met

Embodiment Construction

[0025] Such as Figure 2 to Figure 4 Shown. In the picture, the worktable moves forward and backward, cylinder rod 1, operation table 2, electron gun 3, workpiece welding vacuum chamber 4, welding chamber vacuum system 5, tilt work table 6, parts small rotation motor 7, work table indexing motor 8, work table Ascending and descending cylinder 9, electric control cabinet 10, inclined worktable support plate 11, workpiece mandrel 12, gear 13, gland 14, part positioning plate 15. Each tilting table 6 is equipped with four fixture stations, and the table spindle rotation system and indexing system are installed below. Through the spindle transmission system, the spindle drives the four-station workpiece to rotate and weld. The spindle is driven by 86BYG stepping motor The outer shaft of the main shaft has a vortex and turbine pair, which drives the upper four-station fixture gearbox to rotate the welded parts to ensure that the parts are welded uniformly along the entire circumference....

Abstract

The invention relates to a workbench-inclined multi-station electron beam welding technique and a device thereof, pertaining to the technical field of vehicle transmission gears and friction disc welding. The invention mainly provides an electron beam welding technique for welding a gear and a friction disc and a device thereof. The technical process comprises the steps as follows: the gear and friction disc to be welded are placed in a fixture; the fixtures are loaded in fixture stations on two inclined workbenches one by one; one of the inclined workbenches is conveyed to a vacuum chamber and the vacuum chamber is vacuumized; the gears and the friction discs in the fixtures are welded one by one; the inclined workbench in the vacuum chamber is then taken out and the other inclined workbench is conveyed into the vacuum chamber; and the gears and friction discs are welded one by one. The welding device comprises that a supporting plate is provided with two inclined workbench systems which are completely the same and an inclination angle of 13.5-16.5 degrees is formed between the two inclined workbench systems; the device further comprises a fixture station arranged on the workbench, a principal shaft driving system, an indexing system and a mechanism for moving the supporting plate of the workbench. The welding technique and the device of the invention are mainly used for welding friction discs and gears of each stage of a BE transmission case.

Description

Technical field [0001] The invention belongs to the technical field of welding of automobile gearbox gears and friction discs. Specifically, it relates to a process and device for welding each gear of a BE gearbox with a friction disc. Background technique [0002] The welding process requirements of Shenlong BE gear parts are as follows figure 1 Shown. Welding depth: 4(+0.5, -0.3)mm; Welding width: 3±1mm; The gap between the friction plate 16 and the gear 13 joint surface is ≤0.03mm, the distance between the left and right positions of the weld on the cross section and the surface of the inner hole is: BE1 , 2 gears: 7.55mm (maxi), 8.05mm (mini), BE3, 4, 5 gears: 9.45mm (maxi), 9.95mm (mini). [0003] The French PSA Group uses two different types of welding processing methods, laser welding and electron beam welding, to weld gears and friction disks, and both can meet product quality requirements and production capacity requirements. However, the design capacity planning of She...
