Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic riveter driving tool positioning system which facilitates positioning of driving tools.
The concentricity and surface straightness of the manually driven driving tool are accurately obtained, and the workability is improved.

[0002]

2. Description of the Related Art Conventionally, when riveting rivets on a large panel, for example, on an outer panel of an aircraft, the number of rivets is enormous. Drilling, tacking and finishing are all performed automatically. However, relatively small panels or panels with special shapes that do not have the same shape require a considerable amount of time to be set up and set up by an automatic machine, and small parts must be large. It is inefficient because it is processed by a machine of a shape. In such a case, an electromagnetic riveter by hand is employed.

FIG. 4 is a diagram showing the configuration of a manually operated electromagnetic riveter, in which workers not shown on both sides of the panel 20 hold the electromagnetic riveter main bodies 21 and 22 by holding the handles 25 and 26, respectively, and align them with each other. , The gun switches 29 and 30 are pulled and driven. Reference numerals 23 and 24 denote wires for suspending and supporting the electromagnetic riveters 21 and 22, respectively, from a fixed side (not shown). Reference numerals 25 and 26 denote the above-mentioned handles, which are gripped and operated by workers, respectively, and reference numerals 27 and 28 denote hammers, which are generated when a current flows through the electromagnetic coils in the electromagnetic riveter bodies 21 and 22. It instantly projects forward due to the repulsive force of the magnetic force.

In the electromagnetic riveter having the above-described structure, a hole is formed in the panel 20 for inserting a rivet into a position where a rivet is to be driven in another process. When driving a rivet, first, a rivet is inserted into a hole to be driven. After that, the operators from both sides of the panel 20 respectively use the electromagnetic riveter body 2.
Holding the handles 25, 26 of the first and second 22 and moving the main bodies 21, 22 suspended from the ceiling up and down, right and left, and back and forth,
The ends of the hammers 27 and 28 are aligned with the positions of the rivets.
9 and 30, each is pulled to energize the electromagnetic coil, and the rivets are struck from both sides at the tips of the hammers 27 and 28, thereby driving the rivet. The electromagnetic coils are respectively connected to control units (not shown), and are energized by the operation of the gun switches 29 and 30.

FIGS. 5A and 5B are cross-sectional views showing a state of the rivet. FIG. 5A shows a state before the rivet and FIG. 5B shows a state after the rivet. 5A shows a state in which the hammers 27 and 28 are in a standby state before the rivet, and the rivet 31 is inserted into the panel 20 in advance by making a hole.
In (b), the hammers 27 and 28 protrude from each other, and the end 31b and the head 31a of the rivet 31 are hit with the hammers 27 and 28, respectively. The state is shown. In this way, two operators operate the electromagnetic riveter main bodies 21 and 22 from both sides of the panel 20, and the panel 20 is sequentially driven.

[0006]

As described above, a conventional driving tool for a panel of an aircraft or the like is mainly used for a large-sized panel or a panel for mass production, mainly by a pneumatic hand tool or a large-sized automatic machine. In addition, a small panel or a panel having a complicated shape is driven by a manual operation using an electromagnetic riveter as described with reference to FIG. 4. In particular, the operation of the electromagnetic riveter is performed by using two electromagnetic riveter main bodies. Are suspended in independent balancer systems, so it is difficult to adjust the ends of both hammers to the positions to be driven, and it takes a considerable amount of time. Further, unless the straightness of the hammer tip and the rivet end face is correctly adjusted, the performance such as the crimping force by the rivet after the driving is not satisfied with the required value. Moreover, the driving points are considerable in a single panel, and it takes a considerable time for each driving to adjust the alignment and to obtain the flatness of the panel. I was

Accordingly, the present invention operates an electromagnetic riveter,
In the case of manually driving the rivet, the positioning of the hammer of the two electromagnetic riveters and the flatness between the hammer and the driving rivet can be performed accurately in a short time, and the electromagnetic riveter can be manually operated. It is an object of the present invention to provide an electromagnetic riveter driving tool positioning system with significantly improved work efficiency.

The present invention provides the following means (1) to (3) to solve the above-mentioned problems.

(1) An electromagnetic riveter is hung on both sides of a panel to be riveted, and the electromagnetic riveters on both sides are gripped by an operator to adjust concentricity and surface straightness at a position to be riveted. After that, in the electromagnetic riveter system which drives the electromagnetic riveters on both sides to drive the electromagnetic riveters into the panel, the electromagnetic riveters can be moved back and forth to the left and right while maintaining the concentricity between the two electromagnetic riveters. A connecting frame to be connected,
Three sensors arranged to face the panel on the front surfaces of the electromagnetic riveters and measuring a distance between the panels, a display unit attached to the electromagnetic riveter, Signals from the three sensors of the electromagnetic riveter are input, and if all three detected values fall within a preset range, a signal indicating that the straightness has not been achieved is output. And a control device for sending to the display unit.

An electromagnetic riveter driving fastener positioning system, wherein when input, the two electromagnetic riveters are controlled to operate as set.

In (1) of the present invention, the concentricity of the electromagnetic riveters is determined by mutually interposing the panels on which the electromagnetic riveters are to be driven because the electromagnetic riveters are connected by a connecting frame and the concentricity is secured. You only need to move it forward. Regarding the surface straightness, three sensors are arranged on the same surface of the front surface of the electromagnetic riveter so as to face the panel surface to be riveted. These sensors emit, for example, ultrasonic waves and reflect light reflected from the panel surface. The waves are received and these signals are input to the controller. The control device checks whether the time obtained from the signals from these three sensors or the distance calculated from these times is within a preset range,
If the signals of all three sensors fall within the set range, the plane on which the three sensors are mounted is almost parallel to the panel surface, so it is determined that the plane straightness has been obtained. It is determined that it cannot be obtained, and the signal is sent to the display unit to be displayed.

Therefore, the operator moves and adjusts the position of the electromagnetic riveter by looking at the display on the front of the electromagnetic riveter.
Accurate flatness can be obtained simply by looking at the display that the flatness has been obtained on the display unit, and since the concentricity of both electromagnetic riveters is ensured by the connection frame, concentricity and straightness can be obtained. The degree can be obtained with high precision and easily, and a manual driving operation using an electromagnetic riveter can be performed with high efficiency.

In (2) of the present invention, the display section is provided with, for example, an indicator lamp which lights up in green when the straightness is obtained, and otherwise has a structure like an indicator lamp which lights up in red. In addition, the worker can easily look at this and adjust the position of the electromagnetic riveter, thereby improving work efficiency.

In (3) of the present invention, since the operation signals of the electromagnetic riveters on both sides do not operate independently of each other but operate only after both signals are input, the work safety and the driving performance are sufficiently secured. Things.
