If the workpiece is displaced during the welding process, the welding point may deviate from the designed position, resulting in uneven welds or insufficient strength of the welding joint, thus affecting the quality and reliability of the welding. Through the mutual cooperation among components such as the first pressing plate and the mounting plate above, it is difficult to fix the top of the workpiece on the rectangular plate with the pressing plate, and it is difficult to ensure that the workpiece maintains a stable position and orientation during the welding process, which needs to be improved. Summary of the Utility Model

[0005] The utility model provides a welding machine convenient for positioning, which solves the problems of a welding machine convenient for positioning in the related art.

[0006] The technical solution of the present utility model is as follows: A welding machine convenient for positioning, including a support rod fixedly connected to the top of a bottom plate. A welding auxiliary device is arranged on the top of the bottom plate. The welding auxiliary device includes a rectangular plate, the bottom of the rectangular plate is fixedly connected to the top of the support rod. A short plate is fixedly connected to the side of the bottom plate, a vertical plate is fixedly connected to the top of the short plate, a support plate is fixedly connected to the side of the vertical plate, an electric telescopic rod is fixedly connected to the bottom of the support plate, a cross bar is fixedly connected to the end of the electric telescopic rod away from the support plate. A rotating shaft is rotatably connected to the side of the support plate, a rotating rod is fixedly connected to the circumferential surface of the rotating shaft, the bottom of the cross bar is fixedly connected to the top of the rotating rod, a welding rod is fixedly connected to the bottom of the rotating rod. An L-shaped rod is fixedly connected to the side of the cross bar, an extrusion rod is fixedly connected to the bottom of the L-shaped rod. A notch is formed in the top of the rectangular plate, a connecting plate is fixedly connected to the inner wall of the notch, a thin rod penetrates through the side of the connecting plate, an inclined plate is fixedly connected to the circumferential surface of the thin rod, and a pressing plate is fixedly connected to the side of the inclined plate.

[0007] Further, there are two pressing plates, and they are symmetrically arranged along the vertical central axis of the inclined plate. There are two connecting plates, and they are symmetrically arranged along the vertical central axis of the inclined plate. Having two pressing plates is beneficial for more stable and certain extrusion of the workpiece, reducing the possibility of displacement of the workpiece.

[0008] Further, the bottom plate is located on the displacement track of the pressing plate, the inclined plate is located at the bottom of the extrusion rod, and the inclined plate is located on the displacement track of the extrusion rod. Since the inclined plate is located on the movement track of the extrusion rod, the inclined plate will be extruded.

[0009] Further, an inclined rod is fixedly connected to the inner wall of the notch, a first spring is fixedly connected to the side of the inclined rod, and the end of the first spring away from the inclined rod is fixedly connected to the side of the inclined plate.

One end of the spring telescopic rod away from the rectangular rod is fixedly connected with a pressing block. A baffle is fixedly connected to the top of the hydraulic cylinder. When the cross bar moves downward, it will drive the rectangular rod to move downward. When the rectangular rod moves downward, it will drive the spring telescopic rod to move downward. When the spring telescopic rod moves downward, it will drive the trigger rod to move downward. The trigger rod is relatively long. When the trigger rod moves downward, it will first contact the baffle. As the cross bar continues to move downward, the trigger rod will come into contact with the baffle. During the movement of the trigger rod, it will be blocked. The baffle will squeeze the trigger rod to move towards the side close to the cross bar, driving the spring telescopic rod to retract backward. In this way, when the spring telescopic rod moves downward, the pressing block will not squeeze the first push rod. When the spring telescopic rod moves upward, it will drive the pressing block to move upward. During the upward movement of the pressing block, it will squeeze the triangular block. By the inclined surfaces of the pressing block and the triangular block being in contact, the pressing block will squeeze the triangular block and the first push rod into the interior of the hydraulic cylinder. The first push rod pushes the piston inside the hydraulic cylinder to move, and the piston pushes the liquid inside to move. The liquid will push out the second push rod at the other end of the hydraulic cylinder.

[0011] Further, the baffle is located on the displacement track of the trigger rod. The pressing block is arranged in a triangular shape. The pushing plate is located on the side surface of the rectangular plate. When the spring telescopic rod moves downward, it will drive the trigger rod to move downward. The trigger rod is relatively long. When the trigger rod moves downward, it will first contact the baffle. As the cross bar continues to move downward, the trigger rod will come into contact with the baffle. During the movement of the trigger rod, it will be blocked. The baffle will squeeze the trigger rod to move towards the side close to the cross bar, driving the spring telescopic rod to retract backward. In this way, when the spring telescopic rod moves downward, the pressing block will not squeeze the first push rod.

[0012] Further, a second spring is fixedly sleeved on the circumferential surface of the second push rod. One end of the second spring away from the second push rod is fixedly connected to the side surface of the hydraulic cylinder. The design of the second spring is beneficial for the first push rod to automatically reset when it is not squeezed.

[0013] Furthermore, a collection box is fixedly connected to the side surface of the rectangular plate. A number of support rods are provided, grouped in pairs and symmetrically arranged along the vertical central axis of the bottom plate. After the welded workpiece is pushed away from the rectangular plate, the collection box is located opposite the pushing plate, and the workpiece will be pushed into the interior of the collection box for automatic collection.

The design of the universal wheels is beneficial to driving the movement of the entire device.

[0016] The working principle and beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, through the mutual cooperation among components such as the electric telescopic rod, connecting plate, pressing plate, and extrusion rod inside the welding auxiliary device, it is realized that the movement of the inclined plate will drive the movement of the pressing plate, and the pressing plate will press on the surface of the rectangular plate, so that the top of the workpiece placed on the rectangular plate can be pressed, and then welding can be carried out. The workpiece will not displace. By fixing the top of the workpiece on the rectangular plate through the pressing plate, it can ensure that the workpiece maintains a stable position and direction during the welding process.

[0018] 2. In the present utility model, through the mutual cooperation among components such as the hydraulic cylinder, push rod one, and spring telescopic rod inside the welding auxiliary device, it is realized that the welded workpiece is pushed away from the rectangular plate. The collection box is located opposite the pushing plate, and the workpiece will be pushed into the interior of the collection box for automatic collection. It means that when the welding rod moves downward for welding, the workpiece will not be automatically pushed away. When the welding rod finishes welding the workpiece, the pushing plate will push the workpiece away from the rectangular plate to achieve the effect of automatic collection. Through the design of the pushing plate and the collection box, the welded workpiece can be automatically pushed into the interior of the collection box. This automatic collection function eliminates the need for manual intervention, makes the welding process more continuous and efficient, and thus improves the overall efficiency of the production line.

[0029] There are two pressing plates 316, and they are symmetrically arranged along the vertical central axis of the inclined plate 315. There are two connecting plates 313, and they are symmetrically arranged along the vertical central axis of the inclined plate 315.

[0032] In this embodiment, the workpiece to be welded is placed on the top of the rectangular plate 31. The electric telescopic rod 35 is started. When the electric telescopic rod 35 extends downward, the downward extension of the electric telescopic rod 35 will drive the cross bar 36 to move downward.

[0033] Embodiment 2

[0034] As Figures 3 to 5As shown, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a rectangular rod 319 is fixedly connected to the side of the cross bar 36. A spring telescopic rod 320 is fixedly connected to the side of the rectangular rod 319. One end of the spring telescopic rod 320 away from the rectangular rod 319 is fixedly connected with a pressing block 322. A touch rod 321 is fixedly connected to the top of the spring telescopic rod 320. A cylinder 323 is fixedly connected to the top of the rectangular plate 31. One end of the cylinder 323 away from the rectangular plate 31 is fixedly connected with a hydraulic cylinder 324. A push rod 325 penetrates through one end of the hydraulic cylinder 324. A push rod 326 penetrates through the end of the hydraulic cylinder 324 away from the push rod 325. One end of the push rod 326 away from the hydraulic cylinder 324 is fixedly connected with a pushing plate 329. One end of the push rod 325 away from the hydraulic cylinder 324 is fixedly connected with a triangular block 327. One end of the spring telescopic rod 320 away from the rectangular rod 319 is fixedly connected with a pressing block 322. A baffle 330 is fixedly connected to the top of the hydraulic cylinder 324. When the cross bar 36 moves downward, it will drive the rectangular rod 319 to move downward. When the rectangular rod 319 moves downward, it will drive the spring telescopic rod 320 to move downward. When the spring telescopic rod 320 moves downward, it will drive the touch rod 321 to move downward. The length of the touch rod 321 is relatively long. When the touch rod 321 moves downward, it will first contact the baffle 330. As the cross bar 36 continues to move downward, the touch rod 321 will contact the baffle 330. During the movement of the touch rod 321, it will be blocked. The baffle 330 will squeeze the touch rod 321 to move toward the side close to the cross bar 36, driving the spring telescopic rod 320 to retract backward. In this way, when the spring telescopic rod 320 moves downward, the pressing block 322 will not squeeze the push rod 325. When the spring telescopic rod 320 moves upward, it will drive the pressing block 322 to move upward. During the upward movement of the pressing block 322, it will squeeze the triangular block 327. By the inclined surfaces of the pressing block 322 and the triangular block 327 being in contact, the pressing block 322 will squeeze the triangular block 327 and the push rod 325 into the interior of the hydraulic cylinder 324. The push rod 325 pushes the piston of the internal hydraulic cylinder 324 to move, and the piston pushes the internal liquid to move, and the liquid will push out the push rod 326 at the other end of the hydraulic cylinder 324.

[0035] The baffle 330 is located on the displacement trajectory of the trigger rod 321. The extrusion block 322 is set in a triangular shape. The push plate 329 is located on the side of the rectangular plate 31. When the spring telescopic rod 320 moves downward, it will drive the trigger rod 321 to move downward. The trigger rod 321 is relatively long. When the trigger rod 321 moves downward, it will first contact the baffle 330. As the cross bar 36 continues to move downward, the trigger rod 321 will come into contact with the baffle 330. During the movement of the trigger rod 321, it will be blocked. The baffle 330 will squeeze the trigger rod 321 to move towards the side close to the cross bar 36, driving the spring telescopic rod 320 to retract backward. In this way, when the spring telescopic rod 320 moves downward, the extrusion block 322 will not squeeze the first push rod 325.

[0036] A second spring 328 is fixedly sleeved on the circumferential surface of the second push rod 326. One end of the second spring 328 far from the second push rod 326 is fixedly connected to the side of the hydraulic cylinder 324. The design of the second spring 328 is beneficial for the first push rod 325 to automatically reset when the first push rod 325 is not squeezed.

[0037] A collection box 331 is fixedly connected to the side of the rectangular plate 31. There are several support rods 2, grouped in pairs and symmetrically arranged along the vertical central axis of the bottom plate 1. The welded workpiece is pushed away from the rectangular plate 31. The collection box 331 is located opposite the push plate 329, and the workpiece will be pushed into the interior of the collection box 331 for automatic collection.

[0038] The collection box 331 is located on the side of the push plate 329. The welding rod 39 is located on the top of the rectangular plate 31. The side of the support plate 34 is fixedly connected with a metal material. There are two L-shaped rods 310, which are symmetrically arranged along the vertical central axis of the cross bar 36. The metal support plate 34 is not easily damaged and can be used for a long time.

[0039] Universal wheels 4 are provided at the bottom of the bottom plate 1. A cushion plate is fixedly connected to the top of the rectangular plate 31. A protective pad is fixedly connected to the side of the pressing plate 316. The triangular block 327 is located on the displacement trajectory of the extrusion block 322. The design of the universal wheels 4 is beneficial for driving the entire device to move.

[0040] In this embodiment, when the cross bar 36 moves downward, it will drive the rectangular rod 319 to move downward. When the rectangular rod 319 moves downward, it will drive the spring telescopic rod 320 to move downward. When the spring telescopic rod 320 moves downward, it will drive the touch rod 321 to move downward. The touch rod 321 is relatively long. When the touch rod 321 moves downward, it will first contact the baffle 330. As the cross bar 36 continues to move downward, the touch rod 321 will come into contact with the baffle 330. During the movement of the touch rod 321, it will be blocked. The baffle 330 will squeeze the touch rod 321 to move toward the side close to the cross bar 36, driving the spring telescopic rod 320 to retract backward. Therefore, when the spring telescopic rod 320 moves downward, the extrusion block 322 will not squeeze the first push rod 325. When the spring telescopic rod 320 moves upward, it will drive the extrusion block 322 to move upward. During the upward movement of the extrusion block 322, it will squeeze the triangular block 327. By the fit between the inclined surface of the extrusion block 322 and the inclined surface of the triangular block 327, the extrusion block 322 will squeeze the triangular block 327 and the first push rod 325 into the interior of the hydraulic cylinder 324. The first push rod 325 pushes the piston of the internal hydraulic cylinder 324 to move, and the piston pushes the internal liquid to move. The liquid will push out the second push rod 326 at the other end of the hydraulic cylinder 324. At this time, the welding rod 39 has completed welding. As the cross bar 36 moves upward, the push plate 329 is located on the side of the rectangular plate 31, and it will push the welded workpiece away from the rectangular plate 31. The collection box 331 is located opposite the push plate 329, and it will push the workpiece into the interior of the collection box 331 for automatic collection. This means that when the welding rod 39 moves downward for welding, it will not automatically push the workpiece away. When the welding rod 39 finishes welding the workpiece, the push plate 329 will push the workpiece away from the rectangular plate 31, achieving the effect of automatic collection. Through the design of the push plate 329 and the collection box 331, the welded workpiece can be automatically pushed into the interior of the collection box 331. This automatic collection function eliminates the need for manual intervention, makes the welding process more continuous and efficient, and thus improves the overall efficiency of the production line.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
