Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a jig for positioning a door glass with respect to a door of a satsileless type of an automobile.

(Prior Art) Conventionally, as such a door glass positioning jig, for example, as disclosed in Japanese Patent Laid-Open No. 59-220580, an automobile door is attached to a frame-shaped jig body fixed to the floor. and detect the raised end position, front/rear position, and fallen position of the door glass to be assembled to the door using a plurality of measuring tools attached to predetermined positions of the jig main body, and adjust those positions. Accordingly, it is known that the door glass is positioned relative to the door.

(Problem that the invention aims to solve) However, in the conventional door glass positioning jig mentioned above, the height from the floor to each measurement tool is set to be constant, so when the car model changes, the door glass positioning jig is fixed. Since the rising end position, etc. also changes, it is necessary to prepare a dedicated door glass positioning jig for each car model, in which each measuring tool is placed corresponding to the rising end position, etc. of the door glass of each car model. The problem was that it was difficult to get used to, and that it was uneconomical due to increased costs.

In addition, when doors of different vehicle models are brought into the door glass assembly line, the jig must be replaced each time, resulting in lost time and reduced work efficiency.

The present invention was developed in consideration of these points, and its purpose is to position the jig body on the door of each car of different types, measure the rising end position of the door glass, etc. By displaying the difference between the data and the regular door glass positioning data, even if the door glass of different car models is used, there is no need to replace the door glass positioning jig as in the conventional method described above, and only one door glass positioning jig can be used. To provide a highly versatile jig that is economical, has improved workability, and allows door glasses of many types of vehicles to be assembled in proper positions. Furthermore, it is an object of the present invention to further improve work efficiency by eliminating the need to measure regular door glass positioning data for each different vehicle model and store it in a storage device, or to selectively output it according to the vehicle model.

(Means for Solving the Problems) In order to achieve the above object, the solution of the present invention is to provide a jig main body that is positionably attached to a door of a suspensionless type of an automobile, and a predetermined position of the jig main body. It is equipped with a plurality of measuring instruments that are attached to the position of the door glass and detect the raised end position, front and rear positions, and tilted position of the door glass, and is provided with regular positioning data and measurements of the door glass of the standard vehicle model. a storage device that stores standard deviation values of regular positioning data of door glasses of different vehicle models with respect to regular positioning data of door glasses of the reference vehicle models; A calculation circuit that compares the deviation value between the stored regular positioning data of the reference vehicle model and the measurement data measured by each of the above-mentioned measuring tools and calculates the difference between the two, and displays the difference calculated by this calculation circuit. This configuration includes a display device.

(Function) With the above configuration, in the present invention, when positioning the door glass with respect to the door of a car, the jig main body is attached to the door so that it can be positioned. A plurality of measuring tools on the tool body are arranged to be able to measure the rising end position of the door glass, and each measuring tool detects the rising end position, front-rear position, and collapsed position of the door glass. The difference between the measurement data measured by each measuring tool and the regular door glass positioning data stored in advance in the storage device is calculated by the calculation circuit, and this difference is displayed on the display. Therefore, the operator only has to adjust the installation position of the door glass to the door so that the difference shown on the display is eliminated, and even if the car model is different, the door glass can be accurately attached to the door using one jig. This means that it can be assembled into

Further, a standard deviation value of the regular positioning data of the door glass between the standard vehicle model and the vehicle model to be measured is stored in the storage device, and the arithmetic circuit measures the standard deviation value as the regular positioning data of the standard vehicle model. Since the difference between the two is calculated by comparing the deviation value with the data obtained, and the difference is displayed on the display, there is no need to select data for each different vehicle model, further improving work efficiency.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIGS. 1 and 2 show a state in which a door glass C is positioned with respect to a door B of a sillless type of an automobile using a door glass positioning jig A according to an embodiment of the present invention. The door glass positioning jig A is equipped with a jig body 1 having a substantially gate-shaped frame shape that is attached to a door B. It is also suspended and supported by a hanging device 4 such as a coil spring.

In addition, both left and right vertical portions 1b, 1 of the jig main body 1
As shown in enlarged detail in FIG. 3, a reference pin 5 and a magnet 6 for positioning are provided at the lower end of b.
While fitting into the predetermined fitting holes 8, 8 of the inner panel _b1 of the door B which has been placed on the door glass assembly station of the transport line 2,
By attracting both magnets 6, 6 to the inner panel _b1 , the jig main body 1 is positioned and supported on the door B so as not to wobble.

Furthermore, a door glass C is attached to the upper horizontal portion 1a of the jig main body 1, and a door glass C is installed in the door B so as to be movable up and down by a window regulator (not shown).
(However, this door glass C is temporarily fixed to the door B via a wind regulator so that it can be assembled into a position.) A pair of measuring tools 9 and 10 are attached to the front and rear for detecting the rising end position of the door glass C. There is. Further, a hanging portion 1c is attached to the upper end horizontal portion 1a, and the hanging portion 1c hangs down from approximately the center thereof.

Further, measuring tools 12 and 13 for detecting the front and rear positions of the door glass C are attached to the upper parts of the vertical parts 1b and 1b of the jig main body 1, respectively.

Each of the measuring tools 9 to 13 described above has the same structure, and the following measuring tool 10 detects the rising end position of the door glass C.
To explain this, the measuring tool 10 is made of a magnescale having a pair of first and second contacts 14 and 15 protruding from its tip so as to be pushed upwardly by the door glass C. The first contactor 14 is for measuring actual measurement data Xi of the door glass C to be assembled to the door B at the door glass assembly station of the conveyance line 2,
The second contactor 15 is for measuring regular positioning data Y of the door glass C in a preset reference vehicle type among a plurality of vehicle types carried into the door glass assembly station. 2nd above
