Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for assembling a rod antenna used in televisions, etc.

[As a tsudono 7p, the upper end of the support assembly, such as the r end of a telescopic multi-stage ball assembly, is pivoted to enable tilting and holding of the ball assembly, which is generally used. has been done. In manufacturing such a rod antenna, after assembling the two-phase three-dimensional bodies separately, the support assembly and the ball assembly are pivotally connected by fitting the two-phase three-dimensional bodies into the phase 41G plate. ing. However, in the past, the four parts of the base metal fitting of the support assembly were fitted with the convex part of the base metal fitting of the ball part assembly, and a phosphor bronze washer of moderate thickness was interposed between them. Since both assemblies were assembled by inserting fixing screws into the protrusions and washers, the following problems occurred.

In other words, the gap between the concave part of the support assembly and the convex part of the ball part assembly is narrow, leaving only the thickness of the washer. The diameter is small, 5 to 6 ml, and the outer diameter of the washer is smaller than the contact surface of the concave and convex parts, so it will be buried in these gaps, and two washers must be inserted on both sides of the convex part. By this,
For example, it is extremely difficult to install a washer. Specifically, these assembly operations involve holding the washer with tweezers, etc., and manually inserting it into the gap between the concave and convex parts, but the two washers cannot be balanced and it is difficult to align the fixing screw holes. This process was troublesome, required a great deal of labor and a long time, and was the least workable in the rod antenna manufacturing process. Note that if the gap between the concave and convex mating parts of both assemblies is large, the concave part will deform inward when the fixing screw is tightened, causing uneven rotational friction during the tilting motion of the ball assembly, making it difficult to smoothly tilt the ball assembly. Since it is impossible to ensure operation and holding force, it is not possible to increase the gap between the concave and convex fitting portions to accommodate these thicknesses so that the washer contacts uniformly when tightening the fixing screw.

The present invention solves the above-mentioned problems and makes it possible to easily pivot by interposing a washer in the concave and convex fitting portions of the support assembly and the ball assembly, thereby improving mass productivity. The purpose of this invention is to provide a possible method for assembling a rod antenna.

In order to achieve this object, the rough angle method of the rod antenna according to the present invention includes a washer part and a connecting part intersecting 77 between the friction parts of the concave and convex parts of the support body of the rod antenna and the pole part assembly. Hold the two continuous bands punched out in a tensioned state, interpose these hollow parts, fit the concave and convex parts, and pivotally connect them. Both assemblies and the continuous band are integrally transported intermittently to press the connecting portions and separate and remove the connecting portions from a hook 1 previously formed at the boundary between these connecting portions and the washer portion. , transport stop ■ - is carried out sequentially during the transfer stop.

First, embodiments of the present invention will be explained with reference to the drawings.

In the figure, reference numeral 1 indicates a fixed base, and 1 of this fixed base 1
A plurality of support recesses ii4+a having an arc-shaped cross section are provided on the surface 1-
Guide grooves 1b, which are deeper than the support grooves 18 and are perpendicular to the support grooves 18, are formed at regular intervals along the support grooves 18. Also,? , No. 1 2 is a continuous band from phosphor bronze. , Continuous band 2
In this case, the solid part 2a and the connecting part 2b are formed by intersecting n, and the distance f of the solid part 2d is made to be the same as the interval of "-2 branches J, '+ concave vortex 1d," A notch portion 2C like a V-groove is formed at the boundary between the connecting portion 2b and the connecting portion 2b. C, the continuous band 2 extends from the coiled part a provided on one side of the fixed base 1 to correspond to the guide groove 1b.
The upper and lower two are let out in parallel, and the washer portions 2a are arranged at positions corresponding to the support grooves 1a, respectively. The support assembly 3 and the pole part assembly 4, which were assembled separately in the same manner as the regular 6, are placed in the support groove 18 of the fixed base 1, and then inserted into the recess 3b of the base metal fitting 3a of the support assembly 3. and the convex portion 41) of the base metal fitting 4a of the ball portion 11 solid 4 are supplied by appropriate means so that they face each other across the guide groove 1b. The continuous band 2
is maintained in a tensioned state, and the support body assembly 3 is advanced toward the guide vortex 1b side, and the recess 3b is fitted into the washer part 28 of the continuous band 2, so that these are supported on the inner surface of the recess 31). Next, advance the ball part assembly 4 to the guide groove 1b side, insert the convex part 4b into the concave part 3b via the washer part 2a, and insert the fixing screw 5 into the concave part 3b from above using an appropriate screw. /
'j hole, 1 hole in one of the strawberry parts 2a, and a hole in the convex part 41).

The support body assembly 3 and the ball part assembly 4 are pivoted by inserting it into the hole in the lower comb 1T part 2a and tightening it into the tapped hole in the lower part of the recess 3b. After that, the support groove 1a
Move the movable platform 6, which has a plurality of grooves 68 facing each other, onto the top. Then, the pole assembly 4 is fitted into the groove 68, the moving table 6 is moved laterally, the two-phase solid body 3.4 and the continuous band 2 are integrally transferred to the right side of the figure, and the moving table 6 is lowered. Then, it is supported in the next supporting groove 18, and only the moving table 6 is returned to the operating position. Then, the above-described operation is repeated using the supporting groove 18 which has become empty after both assemblies 3.4 have been transferred. By doing so, the rod antennas that have already been placed together maintain the correct spacing between the continuous bands 2, and the fitting between the concave portion 3b and the convex portion 4b, which will be assembled later, is performed smoothly and stably. As described above, the rod antenna connected by the continuous band 2 and having the two-phase solid body 3.4 pivotally attached thereto is sequentially moved into the support groove 18.
It is intermittently transferred to the one on the right side of the figure. The rod antenna supported by the rightmost support groove 18 is fixed by appropriate means, and the connecting portion 2b of the continuous band 2 is removed by the action of the pressing member 7, completing the assembly of the rod antenna. In other words, a guide bin 7b is attached to the tip of the pressing part 7a formed in a chevron shape, and the guide bin 1b is connected to the connecting part 2b by lowering it while the rod antenna is stopped.
Let's guide you! ') 'i) Press the connecting part 2b with the pressing part 7a. A tensile force is applied to the notch part 2C formed between the connecting part 2b and the washer part 2a. , the rod anchor 7) is separated from the knob 2G, and the connecting portion 2b is removed.

Therefore, by forming the groove J and the eel knob part 2C, the connecting part 2b can be removed even if the outer diameter of the 91911 part 2a is smaller than the fitting part between the fourth part 3b and the convex part 4b. becomes.

b. In the present invention, each of the above-mentioned operations can be performed automatically, b, manually, or fully automated (-), and the vertical position of the continuous band can be determined in advance by the four parts and the convex part. It is preferable to move the JS at a predetermined height corresponding to the fitting portion of the two, and to move it in a direction perpendicular to these axial directions together with both phases.

As explained above, 7. The method of rod unfreezing according to the present invention is the handling of the strip member and the notch between the strip member and the groove side (the richer portion and the connecting portion are provided at the boundary between them). Using two continuous bands connected through the part, and with the continuous body under tension, insert the washer V part between the concave and convex parts of the support assembly and the ball part assembly. These mating operations are easy because they are mated together.
Moreover, this fitting is done by first fitting and pivoting the fitting part, which tensions the continuous band and also positions the washer part to be fitted next, so the two continuous bands are parallel to each other. is maintained, the positions of the holes in each member are easy to match, and pivoting with fixing screws is easy.Since the notch part is provided in the roughly continuous band, even if the washer has a smaller outer diameter than the concave or convex part. The connecting portion can be easily removed to separate the rod antenna, and therefore the support assembly and pole assembly of the rod antenna can be assembled with good workability, resulting in improved mass productivity.
