Problems solved by technology

When using this device for spot spotting, a hand-held electric drill is still required, and the degree of automation is not high. Moreover, the ultrasonic vibration drilling device of this invention can only spot spot circular dimples, and cannot process elliptical dimples.
In addition, the countersinking tool of the invention device will generate a large cutting reaction force when countersinking the workpiece, resulting in machining errors

Embodiment Construction

[0030] see Figure 1~4 , a countersinking elliptical dimple device, including a numerically controlled turntable 2 and a rotating base 4, in order to enable the countersinking elliptical dimple device to accurately move to the workpiece, this countersinking elliptical dimple device can be installed on an industrial robot or a numerically controlled machine tool through a mounting flange 1 and other automated numerical control equipment (not shown in the figure).

[0031] The numerically controlled turntable 2 is linked with the rotating base 4 through the flange 3, the rotating base 4 rotates around the first axis A, and the numerically controlled turntable 2 can control the deflection angle of the rotating base 4.

[0032] The rotating base 4 is fixed with a linear guide rail 30 and a linear guide rail 35 parallel to each other, and the linear guide rail 30 and the linear guide rail 35 are parallel to the first axis A, and a feed ram 7 is slidably installed on the linear guid...

Abstract

The invention discloses an elliptical recess reaming device which comprises a numerical-control turntable, a rotary base, linear guide rails, a feeding ram, a swinging ram, arc guide rails, an electric spindle, a cutter and the like. The rotary base is mounted on the numerical-control turntable and can rotate around a first axis, the linear guide rails are arranged on the rotary base, the feeding ram is slidably mounted on the linear guide rails, the swinging ram is slidably mounted on the feeding ram, the arc guide rails are fixed onto the feeding ram and are used for guiding the swinging ram, the electric spindle is arranged on the swinging ram and is parallel to the first axis, and the cutter is mounted on the electric spindle. The elliptical recess reaming device has the advantages that the feeding ram, the swinging ram and the rotary base are matched with one another according to shape and dimension features of elliptical recesses, so that the cutter can be fed and can swing, angles of swinging planes of the cutter can be changed, and the elliptical recesses can be precisely machined.

Description

technical field [0001] The invention belongs to the field of aircraft digital assembly automatic hole making, and in particular relates to a countersinking elliptical dimple device. Background technique [0002] With the development of the modern aviation industry and the improvement of aircraft performance requirements, the upper and lower panels of the aircraft wing adopt an integral structure to increase the stealth performance of the aircraft and reduce the weight of the aircraft. After the wall board adopts the upper and lower integral structure, it puts forward extremely high requirements for the assembly of the wing. The assembly sequence of the wing is to install the wall plate first, and then install the wall plate. The wall plate and the internal frame are connected by bolts and nuts. After the lower wall plate is assembled and connected with the frame, the upper wall plate is covered on the frame, so the nuts cooperating with the bolts cannot be installed. In or...
