Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dimension measuring device for measuring the dimension of a gap between panel surfaces in a direction orthogonal to the tip of a flange.

[Problems that conventional technology and ideas try to solve]

The gap between the open end of a car's side door, luggage door, etc. and the end of the flange of the body to which the weather strip is attached so that the open end is in contact with it has a large effect on the closing force of the door and water leakage. Control of its dimensions is important. Conventionally, there has been no dimension measuring device that can measure such dimensions from the outside with the door closed, making it difficult to improve measurement accuracy. Furthermore, when measuring at multiple locations along the flange with the conventional device, it was necessary to repeatedly open and close the door and set the measuring instrument, which caused problems in terms of work efficiency.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a dimension measuring device of the type mentioned at the beginning, which allows the gap dimension to be measured from the outside continuously or at multiple points without opening or closing the panel.

[Means for Solving the Problems] In order to achieve this object, the present invention provides a pair of running rollers 13 and 15 having rotating shafts parallel to each other so as to run while sandwiching the flange surface 6. and,
A motor 16 for rotationally driving one of these rollers 15, and a flange tip abutting roller 12 having a rotating shaft 12a perpendicular to the rotating shaft so as to rotate in contact with the flange tip 6a. The traveling base 10 has sliders 21, 21a, and 21b that are displaced in the direction of parallel rotational axes while being biased by a spring 23 so as to be able to return to the original position, and the sliders 21, 21a, and 21b are disposed on the panel surface 5a against the spring bias. Pressed slider 2
1, 21a, 21b is installed, and the traveling position of the traveling base 10 and this position are determined from the rotary encoder 30 attached to rotate in conjunction with the motor 16 and the detection signal of the displacement sensor 20. It is characterized in that it is provided with an attached circuit 2 that measures the gap dimension a with respect to the traveling position and controls the operation of the motor 16.

Note that the symbols in parentheses refer to those in the embodiment described later.

[Effect]

The traveling base 10 is set on the flange 6, and the sliders 21, 2 of the displacement sensor 20 are mounted on the panel surface 5a.
When 1a and 21b are pressed and displaced, the gap dimension a is measured by the attached circuit 2 in accordance with the detection signal of the amount of displacement. When the roller 15 is driven by the motor 16, the traveling rollers 13 and 15 sandwich the flange surface 6, and the roller 12 rotates while coming into contact with the flange tip 6a, so that the traveling base 10 is moved to the flange tip 6a. The attached circuit 2 is connected to the traveling base 1 along with the detection signal of the rotary encoder 30.
By also measuring the amount of movement from the zero reference position, the flange position and the gap size with respect to that position are measured.

It is as follows.

During measurement, the lug gauge door 5 is opened, and the traveling base 10 is placed at the reference position at the lateral end of the flange 6.
The rollers 13 and 15 sandwich the flange 6, and the rollers 12 and 14 sandwich the flange tip 6a and the back surface of the groove 6b. Such clamping is performed by the torsion springs 13c and 14.

When the motor 16 is rotated by operating the key switch, the roller 15 rotates while being pressed against the surface of the flange 6, so the traveling base 10 is moved along the flange tip 6a, and the slider of the displacement sensor 20 is rotated. The roller 21a is the flange tip 6
It is displaced in the vertical direction according to a change in the gap dimension a between panel 5a and panel 5a. The controller 2 processes the detection signals from both sensors 20 and 30, and causes the X-Y recorder 3 to continuously record the gap size a with respect to the position of the flange 6 in conjunction with the movement thereof. Also, during this time, the measurement results are displayed on the numerical displays 2a and 2b one after another instantaneously. If necessary, key switch 2
It is also possible to move the traveling base 10 at predetermined intervals by the operation c, and measure and display each time.
