Description

[0002] ‌Machinery manufacturing refers to the process of using machines, tools and equipment to process raw materials and manufacture various mechanical products.‌ It covers multiple links from design, processing, assembly to commissioning. The machinery manufacturing industry widely involves the production of various mechanical equipment such as power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, and meters.

[0003] Automated welding equipment refers to mechanical equipment that can automatically complete the welding process. It uses the fusion method to realize the automation of the welding process through a computer control system and automatic welding device.

[0004] During the welding process, the workpiece needs to be clamped. When existing automated welding equipment clamps the workpiece, it often uses a clamping block with a fixed angle to rigidly clamp the workpiece. This means that the automated welding equipment can only be used for targets with harder materials during use. When facing targets with slightly softer or thinner materials, the target may be damaged due to clamping, which limits the scope of application of the automated welding equipment and causes a decrease in the welding quality of the target. In addition, when double-sided welding of the welding plate is required, the welding plate needs to be manually flipped to achieve double-sided welding processing, reducing the degree of automation of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0035] See also Figures 1 to 14 In an embodiment of the present invention, an automated welding device for mechanical manufacturing includes an operating table 1 and a frame 2 fixedly arranged on the operating table 1, a welding gun 3 is arranged on the frame 2 through a translation assembly, and the welding gun 3 can be horizontally moved under the action of the translation assembly; The operating table 1 is provided with an elastic clamping assembly, which includes two horizontally symmetrically arranged clamping jaws 4. When the elastic clamping assembly is in operation, the two clamping jaws 4 will approach each other to clamp and fix the workpiece to be welded. The operating table 1 is provided with a driving mechanism, which is connected to the elastic clamping assembly through a transmission structure. When the driving mechanism is running, the two clamping jaws 4 will perform adaptive actions under the interaction of the transmission structure and the elastic clamping assembly. The two clamping jaws 4 will first approach each other to clamp the workpiece, and then remain still waiting for the welding gun 3 to weld the top of the workpiece. Finally, the two clamping jaws 4 will flip over so that the bottom of the workpiece faces upward.

[0036] In this solution, the workpiece to be welded is placed between the two clamping jaws 4, and then the driving mechanism is started. When the driving mechanism is running, the transmission structure will cooperate with the elastic clamping assembly, so that the two clamping jaws 4 are close to each other to elastically clamp and fix the workpiece, and then remain still for a period of time. During this process, the translation assembly will drive the welding gun 3 to weld the top of the workpiece. After the welding is completed, the two clamping jaws 4 will be turned 180 degrees under the action of the transmission structure and the driving mechanism, so that the bottom of the workpiece is facing upward, so that the welding gun 3 can weld the bottom of the workpiece; In the present application, through the mechanical cooperation between the elastic clamping assembly, the driving mechanism, the transmission structure and the translation assembly, the workpiece can be automatically flipped, thereby realizing double-sided welding of the workpiece, and the two clamping jaws 4 will elastically clamp and fix the workpiece under the action of the elastic clamping assembly, ensuring the clamping stability while avoiding damage to the workpiece, thereby improving the scope of application.

[0037] See also Figure 3 , Figure 5 The elastic clamping assembly includes a bracket 5 fixedly arranged on the operating table 1 and a limit rod 6 horizontally fixedly arranged on the bracket 5, and two movable plates 7 are symmetrically slidably arranged on the limit rod 6; A bidirectional screw rod 8 is horizontally rotatably provided on the bracket 5 , and both of the two movable plates 7 are threadedly matched with the bidirectional screw rod 8 .

[0038] In this embodiment, since the two movable plates 7 are symmetrically slidably arranged on the limit rod 6 and the two movable plates 7 are threadedly matched with the bidirectional screw rod 8, when the bidirectional screw rod 8 rotates, the two movable plates 7 will approach each other.

[0039] See also Figure 3 The operating table 1 is fixedly provided with a support 9, the support 9 is rotatably provided with a collar 10, one end of the movable plate 7 is horizontally rotatably provided with a rotating rod 11, one end of the rotating rod 11 passes through the collar 10 and they are movably matched with each other; The inner wall of the collar 10 is provided with a limiting groove 1001 , and the outer wall of the rotating rod 11 is fixedly provided with a limiting protrusion 1101 along its length direction. The limiting protrusion 1101 is located in the limiting groove 1001 and slidably cooperates with each other.

[0040] In this embodiment, since a rotating rod 11 is provided at one end of the movable plate 7 for horizontal rotation, and one end of the rotating rod 11 passes through the collar 10 and movably cooperates with each other, the rotating rod 11 will slide in the collar 10 during the horizontal movement of the movable plate 7; Furthermore, because the limiting protrusions 1101 are located in the limiting grooves 1001 and are slidably matched with each other, when the collar 10 rotates, the rotating rod 11 will also rotate accordingly.

[0041] See also Figure 5 A sleeve 12 is fixedly provided at the other end of the rotating rod 11, and a sliding column 13 is horizontally fixedly provided on one side of the clamping jaw 4 close to the sleeve 12, and the sliding column 13 and the sleeve 12 are slidably matched with each other; A spring 14 is installed inside the sleeve 12 , and two ends of the spring 14 are respectively against the slide column 13 and the inner wall of the sleeve 12 , and the spring 14 is in a compressed state.

[0042] In this embodiment, due to the presence of the spring 14 and the fact that it is in a compressed state, when the two movable plates 7 approach each other, the two rotating rods 11 will drive the two clamping jaws 4 to approach each other through the sleeve 12 and the sliding column 13, thereby clamping and fixing the workpiece to be welded. The spring 14 will be further compressed during this process, and the spring 14 can also be adaptively adjusted according to the size of the workpiece; wherein the sleeve 12 and the sliding column 13 are both configured as square columns.

Both ends of the second spiral groove 1602 are connected to the second straight groove 1601 and the third straight groove 1603, respectively. The second spiral groove 1602 is set to be a half circle, and the second spiral groove 1602 corresponds to the position of the first straight groove 1502; A first ball 21 is rollingly embedded in the first ring seat 17, and the first ball 21 is also rollingly embedded in the first spiral groove 1501; A No. 2 ball 22 is rollingly engaged inside the second ring seat 18 , and the No. 2 ball 22 is also rollingly engaged in the No. 2 straight groove 1601 .

At the same time, the No. 2 ball 22 still slides in the No. 2 straight groove 1601. Therefore, the second ring seat 18 can only slide and cannot rotate. During this period, the welding gun 3 will weld the workpiece driven by the translation assembly; when the No. 2 ball 22 enters the No. 2 spiral groove 1602 from the No. 2 straight groove 1601 and then enters the No. 3 straight groove 1603, during this process, the second ring seat 18 will rotate 180 degrees and then continue to slide, while the first ring seat 17 can only slide and cannot rotate.
