Description

[0001]
BACKGROUND OF THE INVENTION
The present invention gives a vibration to the instrument panel of the automobile, to a vibrating unit for inspecting the status creaking by the instrument panel between the foreign matter exists and components inside the contact.
[0002]
[Prior art]
Conventionally, an instrument panel is assembled in an instrument assembly line as shown in, for example, Japanese Patent Laid-Open No. 5-69251, and the assembled instrument panel is further transported to a vehicle body assembly line to be subjected to a vehicle body body. Assembled to. Then, the assembled car body is shipped to the market after undergoing a finished vehicle inspection.
[0003]
[Problems to be solved by the invention]
However, in such an instrument panel assembly line or vehicle body assembly line, screwed screws or other foreign objects left behind in the instrument panel or mistakenly mixed, or between assembly parts of the instrument panel Since it is difficult to detect stagnation due to abnormal contact or the like, these abnormalities are sometimes found as user complaints after the finished vehicle is shipped to the market. That is, in the assembly line of instrument panels, many parts and fixtures are assembled or attached, and small screws and other foreign objects used in the assembly process are left behind inside the instrument panel. Or, it may happen that the assembly is completed without the operator's knowledge, and when the specifications are changed, the parts of the instrument panel may not be adjusted accurately and the parts may contact each other abnormally. Occasionally, the assembly may be completed in this state. When an instrument panel assembled in this way is assembled to a vehicle body and shipped, an abnormal noise such as a squeaking noise is generated when the user runs the completed vehicle, which may be subject to market complaints.
[0004]
Therefore, the present invention provides an inspection apparatus that can detect and deal with problems such as the occurrence of abnormal sounds such as stagnation noise by a relatively simple mechanism at the stage of assembling an instrument panel before shipment of such a complete vehicle. The purpose is to eliminate market claims.

DETAILED DESCRIPTION OF THE INVENTION
About Lee Nsu torr instrument panel pressurized Fuso location of the present invention, it will be described with reference to a plan view and a side view of FIG. 2 in FIG. 1. The instrument panel vibration device A is a device that supports and vibrates the instrument panel W, and supports columns 2 made of rubber elastic bodies at four corners of the base 1, and the upper ends of the columns 2. The four corners of the vibration frame 3 of a rectangular (planar mouth type) frame body are connected to each other.
[0007]
Further, at both ends of the lower surface of the long side portion 3a on one side (upper side in FIG. 1) of the vibration frame 3, support ends 4a and 4b projecting inward with a predetermined length for supporting the instrument panel W are provided. The supporting members 4A and 4B are disposed, and the support ends 4a and 4b are formed with receiving surfaces that follow the outer surface of the support portion of the instrument panel W at the tip portions. Further, support members 5A, 5B, 5C, 5D having support ends 5a, 5b, 5c, 5d projecting inward with a predetermined length capable of supporting the instrument panel W are provided on the upper surface of the other long side portion 3b. Are arranged at equal intervals. The support ends 5a, 5b, 5c, and 5d are formed with receiving surfaces that follow the outer surfaces of the support portions of the instrument panel W at the tip portions thereof. And the instrument panel W mounted by receiving the corresponding surface of the instrument panel W to be supported in the vibration frame 3 by the receiving surfaces of the support ends 4a, 4b and the support ends 5a, 5b, 5c, 5d. Can be supported in a positioning state.
[0008]
Further, brackets 6A, 6B, and 6C are erected on the upper surfaces of the long side portion 3a, the short side portion 3c, and the short side portion 3d of the vibration frame 3, and on the outer sides of these brackets 6A, 6B, and 6C. Air cylinders 7A, 7B, and 7C are attached, and the cylinder rods 7a, 7b, and 7c extend through the brackets 6A, 6B, and 6C toward the inside of the vibration frame 3, and the cylinder rods 7a, 7b , 7c are attached with pressing pads 8A, 8B, 8C made of an elastic material such as rubber, and are supported in the vibration frame 3 by the support materials 4A, 4B and the support materials 5A, 5B, 5C, 5D. The instrument panel W can be fixed by being pressed by the pressing pad 8A from one side in the front-rear direction and by the pressing pads 8B and 8C from both sides in the longitudinal direction. The air cylinders 7A, 7B, and 7C are arranged so that the pressing positions of the pressing pads 8A, 8B, and 8C coincide with the actual instrument panel support location in the actual vehicle.
[0009]
Further, the mounting plate 9 is passed between the lower surfaces of the central portion of the short side portion 3d facing the central portion of the short side portion 3c, and the lower surfaces of both end portions thereof are symmetrically interposed via brackets 10 (FIG. 2). The electric motors 11A and 11B are attached. Then, eccentric weights 13A and 13B are attached to the rotating shafts 12A and 12B of the electric motors 11A and 11B, respectively, so that the vibration mechanisms 14A and 14B are configured. That is, the eccentric weights 13A and 13B of the electric motors 11A and 11B are synchronously rotated to generate vibration due to the eccentric weight, and the vibration frame 3 connected to the support column 2 made of an elastic material via the bracket 10 is added. Can be shaken.
[0010]
Since the instrument panel vibration device A is configured as described above, the instrument panel W that has been assembled is placed on the support members 4A and 4B and the support members 5A, 5B, 5C, and 5D and positioned. The air cylinders 7A, 7B, and 7C are operated, and the support portions of the instrument panel W are pressed and fixed by the pressing pads 8A, 8B, and 8C. In this state, when the electric motors 11A and 11B of the excitation mechanisms 14A and 14B are driven, vibrations are generated by the eccentric weights 13A and 13B of the rotary shafts 12A and 12B, and the vibrations on the support column 2 via the bracket 10 are generated. The vibration frame 3 can be vibrated, and the instrument panel W supported and fixed to the vibration frame 3 can be vibrated.
[0011]
The vibration frame 3 is vibrated at a frequency of 200 Hz to 300 Hz, for example, by adjusting the rotation speed of the electric motors 11A and 11B and the weights of the eccentric weights 13A and 13B. The vibration state of the instrument panel W in substantially the same state as the traveling speed can be reproduced, and the vibration state during acceleration or deceleration can be reproduced as necessary. At this time, the instrument panel W If there is foreign matter inside or contact friction between each part of the instrument panel, abnormal noise is generated resonatingly, so that the operator can easily detect the malfunction of the instrument panel W.
[0012]
The instrument panel vibration device of the present invention should be installed anywhere after the instrument panel removal process in the instrument panel assembly line and before the instrument panel assembly process in the vehicle body assembly line. Can do. Further, although the eccentric weights 13A and 13B of the electric motors 11A and 11B are rotated synchronously, they may be asynchronously rotated.
In addition, although the case where the instrument panel is an object to be inspected has been described above, the vibration device of the present invention can also be suitably applied to an object to be inspected other than the instrument panel.
[0013]
【The invention's effect】
According to the present invention, mixed therein incorrectly bolts and nuts or other foreign matter in the assembly stage of the instrument panel, also when there is abnormal contact between the assembled components in the instrument panel, a relatively simple excitation Since it can be detected as an abnormal noise by the apparatus, it is possible to eliminate market complaints by a simple vibration inspection before completion of assembly or before market shipment. Furthermore, in the case of an instrument panel of an automobile, by adjusting the vibration mechanism to a vibration state of 200 to 300 Hz, it is possible to reproduce the vibration of the traveling state of the real vehicle at a constant land traveling speed of 60 km / hour, The vibration inspection can be performed by changing the frequency in accordance with the acceleration or deceleration of the running, and can better respond to the market complaint.
