不発明は、電子管のネック部を封止する封止機における
排気管クランプ機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an exhaust pipe clamping mechanism in a sealing machine for sealing the neck of an electron tube.

をクランプする必要がある。Sealing the neck of the electron tube (for example, heating the end of the neck tube and the stem of the electron gun with a burner to create a melt layer (for example, see Japanese Patent Application Laid-Open No. 62-69434). Step C is , an electron gun is inserted into the neck tube to heat the end of the neck tube and the stem, and while both are in a molten state, the stem side is lifted up by a few millimeters, the molten part is contact welded, and then pulled back to its original state for shaping. In order to hold the stem side so that it does not come off the mount pin when it is pulled down, it is necessary to clamp the 'a electron gun exhaust pipe.

ようになっている。The conventional exhaust pipe clamp mechanism was arranged by inserting the exhaust pipe into the exhaust pipe insertion hole of the mount pin that mounts the electron gun, placing the electron gun on the mount pin, and clamping both sides of the exhaust pipe. The structure is such that two rods are pressed against the exhaust pipe using springs and clamped. That is, the exhaust pipe is forcibly drawn to the center of the exhaust pipe insertion hole and held by two rods.

。10,000 years ago, when assembling the electron gun and stem part (well, the electron gun is assembled based on the stem, and the molten layer on the exhaust pipe is also based on the stem surface. However, the molten layer on the exhaust pipe is , there are variations in the precision range (inclination) in the direction ζ perpendicular to the stem surface.

。In the above conventional technology, since the exhaust pipe is drawn to the center of the exhaust pipe insertion hole, variations in the degree of melting between the exhaust pipe and the stem part result in tilting the child gun part, resulting in misalignment of the center between the electron gun and the neck pipe. arise. If the electron gun and the neck tube are misaligned in this manner, insertion errors are likely to occur when inserting the electron gun into the neck tube. In particular, in a cutless seal that does not have a flared portion at the end of the neck tube, the electron gun is likely to get caught in the neck tube when inserted, resulting in poor insertion.

At least three holding piece insertion holes are provided at right angles and approximately equally spaced, a mount shaft fixed to or integrally formed with the mount pin, and a holding piece slidably inserted into each of the holding piece insertion holes. This is achieved by a configuration including a spring member that independently biases these holding pieces toward the exhaust pipe insertion side, and a bow return means that pulls out the holding pieces to the outside.

In addition, by forming the tip of the holding piece with a straight line I on the surface perpendicular to the exhaust pipe insertion hole, even if the center of the exhaust pipe deviates from the center of the exhaust pipe insertion hole, it can be clamped with point contact.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

面が直線に形成されている。As shown in FIGS. 1 and 2, the electron gun 1 includes an m-element gun section 1a, a stem section 1b, and an exhaust pipe 1c, and the stem section 1b is placed on the mount pin 2 during sealing. The mount pin 2 is fixed to a mount shaft 3, and exhaust pipe insertion holes 2a and 3a are formed at the centers of the mount pin 2 and the mount shaft 3. The mount shaft 3 has three holding piece insertion holes 3b formed at equal intervals at right angles to the exhaust pipe insertion hole 32J. A holding piece 4 is slidably inserted into each of the three holding piece insertion holes 3b, and the front end of the holding piece 4 has an arcuate surface parallel to the exhaust pipe insertion hole 3a, and the front end of the holding piece 4 has an arcuate surface parallel to the exhaust pipe insertion hole 3a. A surface perpendicular to 3a is formed into a straight line.

ネック部を示す。In addition, a spring seat 4a is formed on the holding piece 4 at a portion located outside the mount shaft 3, and a return collar portion 4b is formed at the rear end. Between the spring seat 4a and the return collar portion 4b. The groove of the return lever 5 rotatably supported by the mount shaft 3 is inserted, and a compression spring 6 is disposed between the return lever 5 and the spring seat 4a. A spring holder 7 is fixed to the mount shaft 3, and a compression spring 8 is placed between the spring holder 7 and the return lever 5 to bias the return lever 5 toward the mount shaft 3. is adapted to be rotated by a pull-down lever 9 that is moved up and down by a vertical drive means (not shown).In the figure, 10f indicates the neck portion of the 1 electron tube.

上に載置される。Next, the effect will be explained. First, before the exhaust pipe IC is inserted into the exhaust pipe insertion hole 2a13a, the pull-down lever 9 is in a lower position than the state shown in FIG. That is, when the pull-down lever 9 is lowered, the return lever 5 pushes the return collar 4b one turn outward. As a result, the tips of the three holding pieces 4 are located outside the exhaust pipe insertion hole 3a. In this state, the exhaust pipe IC is inserted into the exhaust pipe insertion holes 2a and 3a, and the stem portion 1b is inserted into the mount pin 2.

hold. That is, the holding force of the exhaust pipe IC is due to the spring force of the compression spring 6 that urges the three holding pieces 4 independently. Therefore, each of the three retaining pieces 4 independently compresses the compression spring 6.
Since the spring knife presses the exhaust pipe IC with three directions of force and one point contact, there is no need to apply excessive force to the exhaust pipe IC.
即ち排気管ICを矯正することなく保持できる。That is, the exhaust pipe IC can be held without being straightened.
また第2図及び第3図に示すように、保持ピース4の先

ンプできる。Furthermore, as shown in FIGS. 2 and 3, the tip of the holding piece 4 is straight in the direction perpendicular to the axis of the exhaust pipe IC, so that the center of the exhaust pipe IC is closer to the center of the exhaust pipe insertion hole 3a. As shown by the two-dot chain line, even if there is misalignment, it can be clamped by point contact from three directions.

生じなく、容易に神大される。Next (the whole clamp mechanism is raised or the neck part 10 is lowered, and the electron gun part 1a is inserted into the neck part 10 as shown in FIG. 4. In this case, the exhaust pipe 1C is straightened as described above). Since the stem part tb and the electron gun part 1a are held perpendicular to the mount pin 2 with reference to the stem part, the electron gun part 1a is inserted into the neck part 10. In this case, there is no center shift between the two, and it is easily achieved.

るので、電子放射性能が向上する。Thereafter, the end of the neck portion 10 and the outer periphery of the stem portion 1b are heated and melted by the burner 11. The entire clamping mechanism, ie, the mount pin 2 and the mount shaft 3, is lifted up by this melting process, and the molten parts are brought into contact and welded. After welding, as shown in FIG. 5, the entire clamping mechanism, ie, the mount pin 2, is lowered by several positions to shape the weld swamp. After that, the pull lever 9 is lowered,
The holding piece 4 moves outward by 1% and the clamp on the exhaust pipe 1c is released. This completes the sealing of the electron gun. The electron gun thus obtained has a neck portion 10
Since the electron gun section 1a is inserted and sealed without tilting the electron gun section 1a, the electron emission performance is improved.
なお、上記実施例においては、保持ピース4が3個の場
合について説明したが、4個でもよい。In addition, in the said Example, the case where the number of holding pieces 4 was three was demonstrated, but it may be four.
fたマウントピン2とマウントシャフト3は別体で形成
した1つの部材でもよい。Alternatively, the mount pin 2 and the mount shaft 3 may be one member formed separately.

低減すると共に%電子管の性能が向上する。According to the present invention, since the at least three holding pieces individually press the exhaust pipe from at least three directions by point contact using the spring force of the compression spring, the exhaust pipe can be held without straightening. Further, since the tip of the holding piece is straight in the direction perpendicular to the axis of the exhaust pipe insertion hole, even if the center of the exhaust pipe is shifted from the center of the exhaust pipe insertion hole, it can be clamped with point contact. These results reduce the possibility of incorrect insertion of the child gun and improve the performance of the electron tube.
