Description
本發明係有關一種真空閥體之焊接結構及其焊接方法與焊接裝置,特別是指一種利用無焊料之內焊方式,以對待焊接物進行內部滿焊,藉以製作出真空閥體。The invention relates to a welded structure of a vacuum valve body, a welding method thereof and a welding device, in particular to a method of welding the object to be welded by using a solderless internal welding method, thereby fabricating a vacuum valve body.
按,現行之真空閥體大都呈中空長扁狀,而不易藉由人工實施內焊作業,因此,為了焊接方便僅能自外部焊接,較常見的作法是,透過人工於閥體外部利用滲透焊方式進行焊接,並於焊接過程中將焊料滲入縫隙內部,藉以全面完整地填滿縫隙而達到閥體之接合,進而實現內部之真空效果。According to the current vacuum valve body, the hollow valve body is mostly hollow and flat, and it is not easy to manually perform the internal welding operation. Therefore, it is only possible to weld from the outside for the convenience of welding. It is more common to use the penetration welding through the outside of the valve body. The welding method is carried out, and the solder is infiltrated into the gap during the welding process, so that the gap is completely and completely filled to achieve the joint of the valve body, thereby realizing the internal vacuum effect.
惟,外部焊接需考量到每一作業者的技術純熟度,且滲透焊係主要使兩接合之部分呈現溶融狀,並填入焊料,然此過程中,閥體接合處會微微變形,導致破壞了閥體本身,進而有產生微小細縫之可能,一旦有細縫產生時,真空閥將無法達到內部真空,影響產品之壽命。However, external welding needs to consider the technical purity of each operator, and the penetration welding system mainly causes the two joint parts to be melted and filled with solder. However, in the process, the valve body joint will be slightly deformed, resulting in damage. The valve body itself has the possibility of producing tiny slits. Once a slit is produced, the vacuum valve will not reach the internal vacuum and affect the life of the product.

Preferably, the connecting member 43 is connected to the positioning block 34 which is closer to one end of the welding torch 21, whereby when the motor 41 drives the guiding rod 42 to rotate, the connecting member 43 The movable seat 30 can be driven to reciprocate on the rail 13 and face the welding torch 21 or away from the welding torch 21 for welding work.
值得一提的是,本發明之活動座30移動速度相當緩慢,約為1分鐘15至22mm,因此,活動座30無特別之夾持結構設計,而僅以相符合尺寸之定位塊33、34與待焊接物200適配,故,針對不同尺寸之待焊接物200,兩定位塊33、34係採螺設方式結合於第一滑塊31與第二滑塊32,以便適時地更換定位塊33、34以供承接不同尺寸大小之待焊接物200。同理,第一滑塊31與第二滑塊32之間隔距離亦根據的待焊接物200之長度設定,如待焊接物200之長度較長時,則選取較長之橫板35,以將第一滑塊31與第二滑塊32之間距調長,以供待焊接物200穩定地放置於活動座30上。It is worth mentioning that the movable seat 30 of the present invention moves at a relatively slow speed, about 15 to 22 mm for 1 minute. Therefore, the movable seat 30 has no special clamping structure design, but only the positioning blocks 33 and 34 of the corresponding size. The two positioning blocks 33, 34 are screwed to the first slider 31 and the second slider 32 for different sizes of the workpieces to be welded 200, so as to replace the positioning blocks in time. 33, 34 for accepting workpieces 200 of different sizes. Similarly, the distance between the first slider 31 and the second slider 32 is also set according to the length of the object to be soldered 200. If the length of the object to be soldered 200 is long, the longer horizontal plate 35 is selected to The distance between the first slider 31 and the second slider 32 is adjusted to allow the workpiece to be welded 200 to be stably placed on the movable seat 30.
如圖6、圖7所示,係為本發明進行內焊作業之示意圖。首先,電焊槍21能預先調整適當之高度,以便活動座30帶動待焊接物200往電焊槍21方向移動,使電焊槍21伸入待焊接物200內部,並沿著待焊接物200之各接合處內緣進行自熔式內焊,較佳地,能使待焊接物200內部兩側各形成一內焊道204,以使待焊接物200焊固成一真空閥體300,如圖8。As shown in FIG. 6 and FIG. 7, it is a schematic diagram of the internal welding operation of the present invention. First, the welding torch 21 can be adjusted to an appropriate height so that the movable seat 30 can move the object to be welded 200 toward the welding torch 21, and the welding torch 21 can be inserted into the interior of the workpiece to be welded 200 and joined along the workpieces to be welded 200. The inner edge is subjected to self-fusing internal welding. Preferably, an inner bead 204 is formed on both sides of the inner portion of the object to be welded 200 to weld the object to be welded 200 into a vacuum valve body 300, as shown in FIG.
藉此,本發明係採用無焊料之內焊作業,如此能達到閥體內部之真空效果,且由於本發明為無焊料焊接,使得內焊道204深度小於待焊接物200之接合處的厚度,如此不易使閥體產生變形,而導致破壞其結構強度,同時,因內焊道204深度較小之故,而不易產生空隙,避免藏污納垢。Accordingly, the present invention employs a solderless internal welding operation such that the vacuum effect inside the valve body can be achieved, and since the present invention is solderless, the inner bead 204 has a depth less than the thickness of the joint of the object to be welded 200, Therefore, it is not easy to deform the valve body, which causes damage to the structural strength. At the same time, since the inner bead 204 has a small depth, it is not easy to generate voids and avoid dirt and dirt.
再者,如圖8所示,真空閥體300能於各接合處之外緣採間隔焊接,以形成複數條外焊道301,外焊道301之長度係小於內焊道204,藉以增加整體之結構強度,延長使用壽命。Furthermore, as shown in FIG. 8, the vacuum valve body 300 can be welded at the outer edge of each joint to form a plurality of outer weld beads 301. The length of the outer weld bead 301 is smaller than the inner weld bead 204, thereby increasing the overall The structural strength and longevity.
進一地說明的是,外焊道301採用間隔焊接,係在於真空閥體300利用氮氣偵測儀進行檢測時,若內焊道204有破損而產生空隙時,氮氣較輕易進入閥體內部,而易於檢測出漏氣之處,以便進行焊接填補;而若是外焊道301採用滿焊,則因接合處受到兩側焊道填充,即使有漏氣之情形發生,亦不易透過氮氣偵測儀進行檢測。Further, the outer bead 301 is welded at intervals. When the vacuum valve body 300 is detected by the nitrogen gas detector, if the inner bead 204 is damaged and a gap is generated, the nitrogen gas easily enters the inside of the valve body. It is easy to detect the leaking place for welding filling; and if the outer bead 301 is full-welded, the joint is filled by the bead on both sides, and even if there is a leak, it is not easy to pass through the nitrogen detector. Detection.
接著,說明本發明之真空閥體之焊接方法,其包括下列步驟:Next, a welding method of the vacuum valve body of the present invention will be described, which comprises the following steps:

將待焊接物200安置於焊台10之活動座30上;以及The object to be soldered 200 is placed on the movable seat 30 of the soldering station 10;
使活動座30朝向電焊槍21移動,俾使電焊槍21伸入待焊接物200內部,並沿著第一板片201與第二板片202之各接合處內緣進行焊接,以使待焊接物200內部兩側形成有內焊道204,進而將待焊接物200焊固成真空閥體300。The movable seat 30 is moved toward the welding torch 21, and the welding torch 21 is inserted into the interior of the workpiece to be welded 200, and is welded along the inner edges of the joints of the first plate 201 and the second plate 202 to be welded. An inner bead 204 is formed on both sides of the inside of the object 200, and the object to be welded 200 is welded to the vacuum valve body 300.
透過本焊接方法,可使真空閥體300之內部完全滿焊,並且避免破壞閥體結構,且為了增加整體之結構強度,延長使用壽命,能於內焊後,針對第一板片201與第二板片202之各接合處外緣係採間隔焊接,以形成複數條外焊道301。Through the welding method, the inside of the vacuum valve body 300 can be completely welded, and the structure of the valve body can be prevented from being damaged, and in order to increase the overall structural strength and prolong the service life, after the internal welding, for the first plate 201 and the first The outer edges of the joints of the two sheets 202 are spaced and welded to form a plurality of outer weld beads 301.
最後,說明本發明之真空閥體之焊接結構,其利用前述之裝置與方式來完成,包括了第一板片201與第二板片202,第二板片202與第一板片201對應接設,並透過內焊接固結,使第一板片201與第二板片202之各接合處內緣形成內焊道204;以及利用蓋板203焊接固結於第一板片201與第二板片202之一端。Finally, the welding structure of the vacuum valve body of the present invention is described, which is completed by the foregoing apparatus and method, and includes a first plate 201 and a second plate 202, and the second plate 202 is connected with the first plate 201. And forming, by internal welding, an inner bead 204 is formed at an inner edge of each joint of the first plate 201 and the second plate 202; and is fixed to the first plate 201 and the second by welding with the cover plate 203 One end of the plate 202.
更進一步地,係於第一板片201與第二板片202之各接合處外緣係採間隔焊接,以形成複數條外焊道301,藉以提昇真空閥體300之結構強度。Further, the outer edges of the joints of the first plate 201 and the second plate 202 are spaced and welded to form a plurality of outer bead 301, thereby improving the structural strength of the vacuum valve body 300.
藉此,本發明係採用電焊槍21固定不動,而待焊接物200朝電焊槍21位移之無焊料內焊作業方式,如此能對於狹窄且呈中空狀之閥體進行焊接,有效地使其達到內部之真空效果,且透過內焊,可避免使閥體產生變形,而導致破壞其結構強度。再者,真空閥體300外緣採間隔焊接,以增加整體之結構強度,延長使用壽命。Therefore, the present invention adopts the solderless internal welding operation mode in which the welding tool 21 is fixed and the workpiece 200 is displaced toward the welding torch 21, so that the narrow and hollow valve body can be welded and effectively achieved. The internal vacuum effect, and through the internal welding, can avoid deformation of the valve body, resulting in damage to its structural strength. Furthermore, the outer edge of the vacuum valve body 300 is welded at intervals to increase the overall structural strength and prolong the service life.
