Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a welding machine for manufacturing electric instruments and equipment. Background Art

[0002] A magnetostrictive level gauge is an electrically driven instrument. Its sensor stem is equipped with a float that moves up and down along the stem in response to changes in the liquid level. Magnetostrictive level gauges are used for industrial level measurement and control in various liquid tanks, including petroleum and chemical raw material storage, industrial processes, biochemicals, pharmaceuticals, food and beverages, tank farm management, underground storage at gas stations, and for monitoring dam and reservoir water levels and sewage treatment.

[0003] The existing spherical float is made by manually placing two hemispherical workpieces on a fixture for docking. The fixed hemispherical workpieces are then cleaned and welded together using a welding torch to form a spherical float. Finally, the welded float is manually removed. However, during welding, the hemispherical workpieces need to be manually loaded, which makes automated batch loading impossible, thus affecting the efficiency of the welding process. In addition, the outer surface of the hemispherical workpiece is an arc, which makes it impossible for existing welding equipment to fully clean the outer surface of the hemispherical workpiece, hindering subsequent welding processes. Moreover, the welding ends of the two hemispherical workpieces are relatively weak. If they are not effectively cooled during welding, they are prone to deformation, resulting in reduced welding quality. Finally, during the discharge process, the welding slag dropped during welding cannot be cleaned up together and must be cleaned manually, increasing the labor intensity of the workers.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The following electrical components are all electrically connected to the peripheral PLC controller.

[0033] Reference Figure 1 - Figure 10A welding machine for manufacturing electric instruments and equipment includes a material table 1, the top of the material table 1 is fixedly connected to a support frame 2, the inner side of the support frame 2 is fixedly connected to a first driving cylinder 3, the output end of the first driving cylinder 3 is fixedly connected to a first connecting plate 4, the first connecting plate 4 is fixedly mounted with a second driving cylinder 5, the output end of the second driving cylinder 5 is fixedly connected to a second connecting plate 6, the second connecting plate 6 is fixedly mounted with a first driving motor 7, the output end of the first driving motor 7 is fixedly connected to a third connecting plate 8, the third connecting plate 8 is fixedly mounted with a second driving motor 9, the output end of the second driving motor 9 is fixedly connected to a fixing fixture 11 through an air-electric slip ring 10, the bottom of the material table 1 is fixedly connected to a supporting leg 12, a loading mechanism 13 is provided on the top of the material table 1, a gas transmission mechanism 14 is provided on the fixing fixture 11, a welding mechanism 15 is provided on the support frame 2, and a blanking mechanism 16 is provided on the top of the material table 1.

[0034] In the embodiment, the loading mechanism 13 includes a fifth driving cylinder 1311 fixedly installed on the top of the material platform 1, the output end of the fifth driving cylinder 1311 is fixedly connected to the sliding plate 1301, the top of the sliding plate 1301 is fixedly connected to the barrel 1302, the bottom of the material platform 1 is fixedly installed with a third driving cylinder 1303, the output end of the third driving cylinder 1303 is fixedly connected to the push plate 1305, a connecting groove 1304 is provided on the inner side of the material platform 1 and the sliding plate 1301, the push plate 1305 is slidably connected to the connecting groove 1304, and a plurality of stacked hemispherical workpieces 1306 are provided on the inner side of the barrel 1302, and the plurality of stacked hemispherical workpieces 1306 are placed on the sliding plate 1301.

[0035] Specifically, during loading, the present invention first stacks the hemispherical workpieces 1306 to be welded together, then feeds the stacked hemispherical workpieces 1306 from the top of the barrel 1302 into the barrel 1302. After entering the barrel 1302, the stacked hemispherical workpieces 1306 are placed on the sliding plate 1301. The third driving cylinder 1303, fixedly mounted at the bottom of the material platform 1, is then activated, causing the output end of the third driving cylinder 1303 to drive the push plate 1305 upward. Because multiple stacked hemispherical workpieces 1306 are placed on the sliding plate 1301, the push plate 1305 can drive the hemispherical workpieces 1306 inside the barrel 1302 to be ejected from the barrel 1302. This method eliminates the need for manual loading of the hemispherical workpieces 1306, thus achieving an automatic feeding function for the hemispherical workpieces 1306.

[0036] Furthermore, in the present invention, when the hemispherical workpieces 1306 stacked inside the barrel 1302 are exhausted, the third drive cylinder 1303 drives the push plate 1305 to retract downward and return it to the inside of the material platform 1. The output end of the fifth drive cylinder 1311 on one side then drives the sliding plate 1301 to slide, allowing the sliding plate 1301 to drive the barrel 1302, which has been exhausted of the hemispherical workpieces 1306, to slide out from above the push plate 1305. Then, the output end of the fifth drive cylinder 1311 on the other side drives the barrel 1302, which still has the hemispherical workpieces 1306 stacked inside, to move to above the push plate 1305 via the sliding plate 1301. This alternating loading method facilitates the filling of the hemispherical workpieces 1306 by the staff.

[0037] In the embodiment, the loading mechanism 13 also includes a support plate 1307 fixedly connected to the outer wall of the barrel 1302, and a fourth driving cylinder 1308 is fixedly installed on the support plate 1307. The output end of the fourth driving cylinder 1308 is fixedly connected to a limiting plate 1309. A movable groove 1310 is opened on the inner side of the barrel 1302, and the limiting plate 1309 is slidably connected to the movable groove 1310.

[0038] Specifically, in the present invention, when a hemispherical workpiece 1306 is pushed out of the barrel 1302 by the push plate 1305 below, the fourth driving cylinder 1308 fixedly installed on the support plate 1307 is started, and the output end of the fourth driving cylinder 1308 drives the limit plate 1309 to slide in the movable groove 1310, so that the limit plate 1309 can clamp and fix the next hemispherical workpiece 1306 from both sides, making it convenient to separate and take out the stacked hemispherical workpieces 1306 one by one.

[0039] In the embodiment, the gas delivery mechanism 14 includes a spiral air tube 1401 arranged in the inner cavity of the fixing clamp 11, one end of the spiral air tube 1401 is connected to an annular air tube 1402, and the annular air tube 1402 is connected to multiple nozzles 1403, and the multiple nozzles 1403 are distributed in a ring shape. An air bag 1404 is fixedly arranged on the inner side of the fixing clamp 11.

[0040] Specifically, in the present invention, when one hemispherical workpiece 1306 is pushed out of the barrel 1302 by the push plate 1305 below and the next hemispherical workpiece 1306 is clamped and fixed from both sides by the limit plates 1309, the output shaft of the second driving cylinder 5 drives the components connected to the second connecting plate 6 to move downward, so that the fixing fixture 11 is located above the hemispherical workpiece 1306. Then, an external air pump supplies gas into the spiral air pipe 1401, so that the gas enters the annular air pipe 1402 through the spiral air pipe 1401 and is finally sprayed toward the hemispherical workpiece 1306 below through the multiple nozzles 1403. At the same time, the second driving motor 9 can drive the multiple nozzles 1403 on the fixing fixture 11 to rotate, and the first driving cylinder 3 can drive the multiple nozzles 1403 on the fixing fixture 11 to move, thereby completely cleaning the dust and impurities on the hemispherical workpiece 1306, and effectively cleaning the hemispherical workpiece 1306 before welding.

[0041] Furthermore, after the present invention thoroughly cleans the dust and impurities from the hemispherical workpiece 1306, the second drive cylinder 5 drives the fixing fixture 11 to continue moving downward and engage the hemispherical workpiece 1306. An external air pump then inflates the airbag 1404, which fills the gap between the hemispherical workpiece 1306 and the fixing fixture 11, securely securing the hemispherical workpiece 1306 within the fixing fixture 11. The second drive cylinder 5 then drives the hemispherical workpiece 1306 inside the fixing fixture 11 upward, separating it from the next hemispherical workpiece 1306 below. The first drive motor 7 then rotates the hemispherical workpiece 1306 to a horizontal position, and the first drive cylinder 3 enables the two hemispherical workpieces 1306 to be docked together.

[0042] In the embodiment, the feeding mechanism 13 further includes a first dust shield 1312 fixedly connected to the outer wall of the limiting plate 1309 , and a second dust shield 1313 fixedly connected to the outer wall of the sliding plate 1301 .

[0043] Specifically, when the present invention cleans the hemispherical workpiece 1306 through multiple nozzles 1403, because the first dust shield 1312 is fixedly connected to the limit plate 1309 and is located above the output shaft of the fourth driving cylinder 1308, and the second dust shield 1313 is fixedly connected to the sliding plate 1301 and is located above the output shaft of the fifth driving cylinder 1311, the first dust shield 1312 and the second dust shield 1313 have a dust-blocking protection effect on the output shafts of the fourth driving cylinder 1308 and the fifth driving cylinder 1311, thereby preventing dust from above from falling directly onto the cylinder output shaft and affecting the service life of the cylinder.

[0044] In the embodiment, the welding mechanism 15 includes a mounting frame 1501 fixedly connected to the support frame 2 , a sixth driving cylinder 1502 is fixedly mounted on the mounting frame 1501 , and a welding gun 1503 is fixedly connected to the output end of the sixth driving cylinder 1502 .

[0045] Specifically, in the present invention, after the two hemispherical workpieces 1306 are docked together, the sixth driving cylinder 1502 on the mounting frame 1501 is started, so that the output end of the sixth driving cylinder 1502 drives the welding gun 1503 close to the welding point of the two hemispherical workpieces 1306, and then the two second driving motors 9 rotate synchronously and drive the two hemispherical workpieces 1306 to rotate, so that the welding gun 1503 can weld the two hemispherical workpieces 1306 together and obtain a float, thereby realizing the welding processing function.

[0046] In the embodiment, the gas delivery mechanism 14 also includes a mounting plate 1405 fixedly connected to the fixing fixture 11, and a storage box 1406 is fixedly connected to the top of the mounting plate 1405. A liquid inlet pipe 1407 is provided on the top of the storage box 1406, and a control valve 1408 is provided on the liquid inlet pipe 1407. The storage box 1406 is connected to the inner cavity of the fixing fixture 11 through a first liquid infusion pipe 1409.

[0047] Specifically, when the present invention performs welding processing on the two hemispherical workpieces 1306, because the storage box 1406 stores coolant, the coolant in the storage box 1406 can be delivered to the inner cavity of the fixing fixture 11 through the first liquid delivery tube 1409. In addition, an external air pump delivers inert gas to the interior of the spiral air tube 1401. When the inert gas is delivered in the spiral air tube 1401, the coolant in the inner cavity of the fixing fixture 11 has a cooling effect on the inert gas. After the inert gas is cooled in the spiral air tube 1401, it is delivered to the annular air tube 1402 and finally sprayed to the welding point of the two hemispherical workpieces 1306 through the nozzle 1403. The cooled inert gas can prevent oxidation of the welding point while also having a cooling effect on the welding point, which can effectively improve the welding effect.

[0048] In the embodiment, the gas delivery mechanism 14 also includes a driving pump 1410 fixedly installed on the top of the storage box 1406, one end of the driving pump 1410 is connected to the inner cavity of the fixing clamp 11 through a second infusion tube 1411, and the other end of the driving pump 1410 is connected to the storage box 1406 through a third infusion tube 1412, and a cooling fan 1413 is fixedly installed on the top of the mounting plate 1405.

[0049] Specifically, when the present invention cools the inert gas in the spiral air tube 1401, the driving pump 1410 can transport the coolant in the inner cavity of the fixing clamp 11 to the storage box 1406 through the second infusion tube 1411 and the third infusion tube 1412. The cooling fan 1413 has a heat dissipation effect on the coolant in the storage box 1406, so that the coolant can circulate and cool down, thereby improving the cooling effect on the inert gas in the spiral air tube 1401.

[0050] In the embodiment, the blanking mechanism 16 includes a discharge channel 1601 fixedly connected to the material platform 1, the top of the discharge channel 1601 is fixedly connected to a discharge hopper 1602, the outer wall of the discharge channel 1601 is fixedly connected to a connecting frame 1603, a seventh driving cylinder 1604 is fixedly installed on the connecting frame 1603, the output end of the seventh driving cylinder 1604 is fixedly connected to a baffle plate 1605, a sliding groove 1606 is opened on the inner side of the discharge hopper 1602, and the baffle plate 1605 is slidably connected to the sliding groove 1606.

[0051] Specifically, when the present invention performs welding processing on two hemispherical workpieces 1306, the seventh driving cylinder 1604 will drive the baffle plate 1605 to slide in the sliding groove 1606 and insert into the drop hopper 1602, and the output end of the eighth driving cylinder 1607 will drive the wind hood 1608 to separate from the top of the drop hopper 1602, so that the welding slag generated during the welding process will fall onto the baffle plate 1605.

[0052] In the embodiment, the blanking mechanism 16 also includes an eighth driving cylinder 1607 fixedly connected to the connecting frame 1603, and the output end of the eighth driving cylinder 1607 is fixedly connected to the wind hood 1608, the wind hood 1608 is matched with the blanking hopper 1602, and an air supply channel 1609 is provided on the top of the wind hood 1608.

[0053] Specifically, in the present invention, after the two hemispherical workpieces 1306 are welded into a float, the eighth driving cylinder 1607 will drive the wind hood 1608 to cover the top of the drop hopper 1602. At this time, the external vacuum pump will extract the welding slag on the baffle plate 1605 through the wind hood 1608 and the air supply channel 1609, making it convenient to clean the welding slag generated during the welding process.

[0054] Furthermore, in the present invention, once the welding slag is cleaned, the output end of the eighth drive cylinder 1607 drives the air hood 1608 to separate from the top of the drop hopper 1602, and the output end of the seventh drive cylinder 1604 drives the baffle 1605 to move out of the interior of the drop hopper 1602. Subsequently, the first drive cylinder 3 drives the docked fixing fixture 11 to separate, and the gas within the airbag 1404 inside the fixing fixture 11 is discharged, causing the welded float to move out of the fixing fixture 11 and fall into the drop hopper 1602. Because the drop hopper 1602 is connected to the discharge channel 1601, the welded float can be discharged through the discharge channel 1601, facilitating the collection of the welded float.

[0055] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
