Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that: when chamfering, the mandrel must not only rotate but also slide axially, and long-term use will lead to wear of the mandrel, and the matching gap between the mandrel and the bushing will become larger, resulting in During processing, the runout of the mandrel becomes larger, the pistol drill shakes, and the size of the chamfer is uneven

Embodiment Construction

[0038] The following is attached Figure 1-3 The application is described in further detail.

[0039] The embodiment of the present application discloses a countersunk rivet hole chamfering adjuster. refer to figure 1 and figure 2 , The countersunk rivet hole chamfering regulator includes a shaft box 1, a shaft sleeve 2 inserted into the shaft box 1 at one end, and a mandrel 3 coaxially arranged in the shaft sleeve 2 and rotatably matched with the shaft sleeve 2, and the shaft sleeve 2 Slidingly matched with the axle box 1 along the axial direction of the mandrel 3 , a stopper 4 is provided between the axle sleeve 2 and the axle box 1 for limiting the sliding distance of the axle sleeve 2 .

[0040] refer to figure 1 and figure 2 The shaft box 1 is hollow inside and has openings at both ends, and a ventilation hole 10 is opened on the outer wall of the shaft box 1 away from the shaft sleeve 2. The ventilation hole 10 is a waist-shaped hole and penetrates the opposite si...

Abstract

The invention relates to a countersunk head rivet hole chamfer adjuster. The countersunk head rivet hole chamfer adjuster comprises a shaft box, a shaft sleeve and a mandrel, one end of the shaft sleeve is inserted into the shaft box, the mandrel is coaxially arranged in the shaft sleeve and is in running fit with the shaft sleeve, the shaft sleeve and the shaft box are in sliding fit in the axis direction of the mandrel, and a limiting piece used for limiting the sliding distance of the shaft sleeve is arranged between the shaft sleeve and the shaft box. The countersunk head rivet hole chamfer adjuster has the advantages that abrasion of the mandrel is reduced, the fit clearance between the mandrel and the shaft sleeve is reduced, shaking of a pistol drill during chamfering is reduced, and the consistency of the chamfering size is guaranteed.

Description

technical field [0001] The present application relates to the field of mechanical processing equipment, in particular to a countersunk rivet hole chamfering adjuster. Background technique [0002] At present, most of the outer skins of aircraft wings and cabins are made of carbon fiber composite materials, and the parts are connected by rivets, and the opening of each rivet hole needs to be chamfered. When chamfering the rivet mouth, it is necessary to adjust the chamfering for different hole diameters, different angles, and different depths. [0003] In the related technology, a pistol drill is generally used to chamfer the rivet hole, and the chamfering knife is installed on the pistol drill, and the staff holds the pistol drill to perform chamfering. A countersink drill sleeve is installed between the drill and the chamfering tool. The countersink drill sleeve mainly includes a shaft sleeve and a mandrel arranged in the shaft sleeve. One end of the mandrel is connected ...
