Technical Field

[0001] This utility model relates to the field of welding technology, specifically a fixed platform for an automatic welding machine. Background Technology

[0002] The fixed platform of an automatic welding machine is a core component used to stably place workpieces and assist in welding operations. When using an automatic welding machine to weld workpieces, the workpieces to be welded need to be fixed using the fixed platform to complete the welding process.

[0003] The existing fixed platforms of automatic welding machines suffer from insufficient adaptability, mainly manifested in the following ways: their fixed mechanisms adopt a uniform clamping mode, making it difficult to stably clamp various types of workpieces. When processing workpieces with significant shape differences, such as planar rectangular steel plates and curved cylinders, traditional rigid clamps may only form line contact between the planar clamp and the curved workpiece, resulting in uneven clamping force distribution, reduced clamping stability, and impact on subsequent welding quality.

[0004] Therefore, a fixed platform for an automatic welding machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed platform for an automatic welding machine to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A fixed platform for an automatic welding machine includes an operating table. A rotating platform is rotatably mounted on the top of the operating table. A limiting groove is fixed on the top of the rotating platform. A double-threaded screw is mounted inside the limiting groove through a bearing. A threaded slider is respectively fitted on the outer sides of both ends of the double-threaded screw through threaded engagement. A fixing component is fixed on the top of each of the two threaded sliders. A handwheel is rotatably mounted on one side of the limiting groove. A rotating shaft is rotatably mounted inside the operating table. The top end of the rotating shaft is fixedly connected to the bottom of the rotating table. A worm gear is fixed at the bottom end of the rotating shaft. A mounting plate is welded to each side of the operating table. A worm is mounted between the two mounting plates through a bearing. The worm gear and the worm wheel are connected through tooth engagement. A first motor is fixed on one side of the mounting plate.

[0006] Preferably, the top of the operating table is provided with an annular groove, and two support sliders are slidably installed inside the annular groove, with the top ends of the two support sliders respectively welded to the bottom of the rotary table.

The output end of the handwheel passes through and extends into the limiting groove and is fixedly connected to one end of the double-threaded screw. The output end of the first motor passes through the mounting plate and is fixedly connected to one end of the worm gear.

[0008] Preferably, the fixing component includes a first fixing seat, and a support slide rod is welded to each of the two sides of the top of the first fixing seat, and a second fixing seat is welded to the top of the two support slide rods.

[0009] Preferably, the first fixing seat and the second fixing seat are respectively provided with an installation groove, and a sliding plate is slidably installed inside the installation groove. A first cylinder is fixed inside the installation groove, and the output end of the first cylinder is fixedly connected to one side of the sliding plate.

[0010] Preferably, a pressure plate is slidably sleeved on the outer side of the two supporting slide rods, and a second cylinder is fixed on each side inside the second fixed seat.

[0013] Compared with the prior art, this utility model provides a fixed platform for an automatic welding machine, which has the following advantages:

[0014] When fixing a planar rectangular steel plate workpiece, the steel plate is pressed between the pressure plate and the top of the first fixing seat, thus firmly fixing the steel plate workpiece. Then, by rotating the handwheel, the double-threaded screw is rotated to adjust the distance between the two fixing components, thereby allowing the two fixed steel plates to align for subsequent welding. When welding and fixing a curved cylindrical workpiece, the curved cylindrical workpiece is inserted between the first fixing seat and the second fixing seat. Then, by controlling the extension of the output end of the first cylinder, the sliding plate is moved towards the workpiece surface, thereby causing the rubber roller to contact and press against the curved cylindrical workpiece.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A rotating platform 3 is rotatably mounted on the top of the operating table 1. A limiting groove 9 is fixed on the top of the rotating platform 3. A double-threaded screw 10 is mounted inside the limiting groove 9 via bearings. A threaded slider 7 is fitted on the outer side of each end of the double-threaded screw 10 via threaded engagement. A fixing component 8 is fixed on the top of each of the two threaded sliders 7. A handwheel 6 is rotatably mounted on one side of the limiting groove 9. A rotating shaft 14 is rotatably mounted inside the operating table 1. The top end of the rotating shaft 14 is fixedly connected to the bottom of the rotating platform 3. A worm gear 13 is fixed at the bottom end of the rotating shaft 14. A mounting plate 4 is welded to each side of the operating table 1. A worm 12 is mounted between the two mounting plates 4 via bearings. The worm 12 and the worm gear 13 are connected via toothed engagement. A first motor 5 is fixed on one side of the mounting plate 4.

[0023] The fixing component 8 includes a first fixing seat 801, and a support slide rod 8011 is welded to each of the two sides of the top of the first fixing seat 801, and a second fixing seat 807 is welded to the top of the two support slide rods 8011.

[0024] The first fixed seat 801 and the second fixed seat 807 are respectively provided with an installation groove 806, and a slide plate 804 is slidably installed inside the installation groove 806. A first cylinder 805 is fixed inside the installation groove 806, and the output end of the first cylinder 805 is fixedly connected to one side of the slide plate 804.

[0025] A pressure plate 803 is slidably sleeved on the outer side of the two support slide rods 8011, and a second cylinder 8012 is fixed on each side inside the second fixed seat 807. The output ends of the two second cylinders 8012 slide through the interior of the second fixed seat 807 and are fixedly connected to the top of the pressure plate 803.

[0026] A rubber anti-slip plate 802 is installed on the top of the first fixing seat 801 and the bottom of the pressure plate 803, and the first fixing seat 801 and the second fixing seat 807 are installed symmetrically.

[0027] A fixing plate 8010 is welded to each side of the slide plate 804. Two rubber rollers 808 are rotatably mounted on one side of the fixing plate 8010. A second motor 809 is fixed to one side of the fixing plate 8010 by bolts, and the output end of the second motor 809 is fixedly connected to the shaft of one of the rubber rollers 808.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, when fixing a planar rectangular steel plate workpiece, the steel plate is placed on top of the first fixing seat 801. Then, by controlling the extension of the output end of the second cylinder 8012, the pressure plate 803 is moved downward, thereby pressing the steel plate between the pressure plate 803 and the top of the first fixing seat 801, thus firmly fixing the steel plate workpiece. Subsequently, by rotating the handwheel 6, the double-threaded screw 10 is rotated. The rotation of the double-threaded screw 10 can control the relative movement of the two fixing components 8, thereby adjusting the distance between the two fixing components 8, so that the two fixed steel plates can be joined together for subsequent welding. When welding and fixing a curved cylindrical workpiece, the output end of the second cylinder 8012 is retracted, causing the pressure plate 803 to move to the second fixing seat 801. At the bottom of 7, the curved cylindrical workpiece is then inserted between the first fixed seat 801 and the second fixed seat 807. Then, by controlling the extension of the output end of the first cylinder 805, the sliding plate 804 is moved towards the workpiece surface, so that the rubber roller 808 contacts and presses the curved cylindrical workpiece. Then, the two fixed components 8 are controlled to move relative to each other so that the two curved cylindrical workpieces are joined together. Then, during the welding process, the controller controls the output ends of multiple second motors 809 to rotate synchronously, driving the rubber roller 808 to rotate, thereby driving the curved cylindrical workpiece to rotate during the welding process, thus completing the curved surface welding operation. This device can improve the adaptability of the fixed platform, can stably clamp various types of workpieces, and improve the welding quality.

[0029] Example 2: The top of the operating table 1 is provided with an annular groove 11, and two support sliders 15 are slidably installed inside the annular groove 11. The top ends of the two support sliders 15 are respectively welded to the bottom of the rotary table 3. Four support legs 2 are welded to the bottom of the operating table 1, and the four support legs 2 are respectively located at the four corners of the bottom of the operating table 1. The output end of the handwheel 6 passes through and extends into the limiting groove 9 and is fixedly connected to one end of the double threaded screw 10. The output end of the first motor 5 passes through the mounting plate 4 and is fixedly connected to one end of the worm gear 12.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by controlling the rotation of the output end of the first motor 5, the worm gear 12 can be rotated. The rotation of the worm gear 12 can drive the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 can drive the rotating table 3 to rotate above the operating table 1. The rotation of the rotating table 3 can change the welding position of the workpiece and improve the flexibility of the device. When the rotating table 3 rotates, the two support sliders 15 welded to the bottom of the rotating table 3 will slide along the opening direction of the annular groove 11, providing stability to the rotating table 3 during the rotation process.

[0031] Working principle: When fixing a planar rectangular steel plate workpiece, the steel plate is placed on top of the first fixing seat 801. Then, by controlling the extension of the output end of the second cylinder 8012, the pressure plate 803 is moved downward, thereby pressing the steel plate between the pressure plate 803 and the top of the first fixing seat 801, thus firmly fixing the steel plate workpiece. Subsequently, by rotating the handwheel 6, the double-threaded screw 10 is rotated. The rotation of the double-threaded screw 10 controls the relative movement of the two fixing components 8, thereby adjusting the distance between the two fixing components 8, so that the two fixed steel plates can be joined together for subsequent welding. When welding and fixing a curved cylindrical workpiece, the output end of the second cylinder 8012 is retracted, causing the pressure plate 803 to move to the bottom of the second fixing seat 807. Then, the curved cylindrical workpiece is inserted into the first fixing seat 801 and the second fixing seat 807. Subsequently, by controlling the extension of the output end of the first cylinder 805, the sliding plate 804 is moved toward the surface of the workpiece, so that the rubber roller 808 contacts and presses against the curved cylindrical workpiece. Then, the two fixed components 8 are controlled to move relative to each other so that the two curved cylindrical workpieces are joined together. Then, during the welding process, the controller controls the output ends of multiple second motors 809 to rotate synchronously, driving the rubber roller 808 to rotate, thereby driving the curved cylindrical workpiece to rotate during the welding process, thus completing the curved surface welding operation. During the welding process, by controlling the rotation of the output end of the first motor 5, the worm gear 12 can be rotated. The rotation of the worm gear 12 can drive the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 can drive the rotating table 3 to rotate above the operating table 1. The rotation of the rotating table 3 can change the welding position of the workpiece, improving the flexibility of the device.
