Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to an adaptive welding displacement device. Background Technology

[0002] A positioner is a specialized welding auxiliary device suitable for repositioning workpieces in rotary welding operations to achieve the ideal processing position and increase welding speed. It can be used in conjunction with manipulators and welding machines to form an automatic welding center, or for workpiece repositioning during manual operations.

[0003] In the existing technology, the positioning equipment used for processing long workpieces is mainly a fixed mounting and clamping mechanism, which cannot flexibly adjust the mounting seat spacing. When dealing with workpieces of different lengths, special mounting fixtures need to be replaced, which leads to an extension of production preparation time. At the same time, if the workpiece is longer than the length of the support frame, the positioning equipment needs to be replaced, which reduces the utilization rate of the equipment. To address these issues, an adaptive welding positioning device is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adaptive welding positioning device, which aims to solve the problem in the prior art that "when facing workpieces of different lengths, special installation fixtures need to be replaced, which leads to a longer production preparation time. At the same time, if the workpiece exceeds the length of the support frame, the positioning equipment needs to be replaced, which reduces the utilization rate of the equipment".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive welding displacement device, comprising a sliding frame, wherein two sets of mounting seats are slidably connected to the upper surface of the sliding frame, and sliding rods are rotatably connected to the inner sidewalls of the two sets of mounting seats near the middle of the sliding frame. An adjustment mechanism is provided on the outer wall of the sliding rod, the adjustment mechanism comprising a support assembly, the support assembly comprising a support frame, the support frame being slidably connected to the inner wall of the sliding rod, a drive motor being mounted on the inner wall of the support frame, a rotating disk being fixedly connected to the output shaft of the drive motor, a sliding groove being formed on the upper surface of the support frame, a sliding block being slidably connected to the inner wall of the sliding groove, an extension plate being fixedly connected to the upper surface of the sliding block, and a connecting plate being fixedly connected to the lower surface of the extension plate.

[0006] As a further description of the above technical solution: The adjustment mechanism includes an extension assembly, which includes a second drive motor. The second drive motor is mounted on the right outer wall of the sliding frame. The output shaft of the second drive motor is fixedly connected to a bidirectional lead screw, and a connecting block is threaded onto the outer wall of the bidirectional lead screw.

[0007] As a further description of the above technical solution: The connecting plate is fixedly connected to the end of the sliding rod away from the mounting base.

[0008] As a further description of the above technical solution: The bidirectional lead screw is rotatably connected to the inner wall of the sliding frame, the connecting block is slidably connected to the upper surface of the sliding frame, and the connecting block is fixedly connected to the lower surface of the mounting base.

[0009] As a further description of the above technical solution: The lower surface of the sliding frame is equipped with casters.

[0010] As a further description of the above technical solution: A support plate is sleeved on the outer wall of the sliding rod, and the support plate is fixedly connected to the upper surface of the sliding frame.

[0011] As a further description of the above technical solution: The extension plate is provided in two sets, and the two sets of extension plates are symmetrically arranged with the center line of the rotating disk as the axis of symmetry.

[0012] As a further description of the above technical solution: The upper surface of the extension plate is provided with an arc-shaped protrusion that fits the edge of the rotating disk but does not contact the rotating disk, so that the upper surface of the extension plate is flush with the rotating disk.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting a support component, the installation and displacement method can be selected according to the size of the workpiece during use. When processing short workpieces, a rotating disk that can be rotated can be used directly to install the support. When processing longer workpieces, two sets of extension plates that extend the relative distance can be extended together with the extension component to install the support. Combined with the rotating disk, three-point positioning is achieved to ensure the installation stability of the workpiece and improve the practicality of the device.

[0014] 2. In this utility model, by setting an extension component, two sets of mounting seats are driven by a bidirectional screw to slide synchronously in opposite directions or in opposite directions, allowing the support component to have a longer installation space. At the same time, the support plate provides radial constraint force when the support component is extended, preventing the support frame from shifting and ensuring rigid support during the flipping process of long workpieces, thereby further improving the effectiveness of the device.

[0017] 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.

[0018] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an adaptive welding positioning device, comprising a sliding frame 1 that allows two sets of mounting seats 2 to adjust their distance. The upper surface of the sliding frame 1 is slidably connected to two sets of mounting seats 2 for rotating and supporting a sliding rod 3 and other components. The sliding rod 3 is rotatably connected to the inner wall of each set of mounting seats 2 near the middle of the sliding frame 1. A motor is installed inside each mounting seat 2 to drive the sliding rod 3 to rotate. The motor inside the mounting seat 2 is an existing structure, which can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. An adjustment mechanism is provided on the outer wall of the sliding rod 3, which can adjust the distance between the two sets of mounting seats 2, allowing the device to accommodate workpieces of different lengths. The adjustment mechanism includes a support assembly 4 for supporting the placement of the workpiece. The support assembly 4 includes a support frame 41 for mounting other components. The support frame 41 is slidably connected to the inner wall of the sliding rod 3. When the mounting seats 2 move, the sliding rod 3 slides along the inner wall of the support frame 41. The extension plate 46 is moved and pulled to allow the device to place longer workpieces for flipping and repositioning. A drive motor 42 is installed on the inner wall of the support frame 41. The drive motor 42 is used to drive the rotating disk 43 to rotate. The output shaft of the drive motor 42 is fixedly connected to the rotating disk 43. When in use, the rotating disk 43 can place smaller workpieces for repositioning and welding. The rotatable rotating disk 43 allows the workpiece to be repositioned at more angles. A sliding groove 44 is opened on the upper surface of the support frame 41 to guide the movement of the sliding block 45. The inner wall of the sliding groove 44 is slidably connected to the sliding block 45 for moving the extension plate 46. The upper surface of the sliding block 45 is fixedly connected to the extension plate 46. The extension plate 46 can serve as a support and fixation platform after the mounting base 2 moves away. A clamping device can also be installed on the upper surface to press and fix the workpiece. A connecting plate 47 is fixedly connected to the lower surface of the extension plate 46. The connecting plate 47 connects the extension plate 46 and the sliding rod 3, so that when the sliding rod 3 moves, it drives the extension plate 46 to move together.

[0019] Reference Figure 1 , Figure 2 and Figure 5 The adjustment mechanism includes an extension component 5, which is used to move the mounting base 2. The extension component 5 includes a second drive motor 51, which is used to drive the bidirectional lead screw 52 to rotate. The second drive motor 51 is installed on the right outer wall of the sliding frame 1 and is fixed by the sliding frame 1. The output shaft of the second drive motor 51 is fixedly connected to the bidirectional lead screw 52, ​​which is used to drive the two sets of mounting bases 2 to move synchronously. The outer wall of the bidirectional lead screw 52 is threaded with a connecting block 53 for driving the mounting base 2 to move. The bidirectional lead screw 52 is rotatably connected to the inner wall of the sliding frame 1 and is supported by the sliding frame 1. The connecting block 53 is slidably connected to the upper surface of the sliding frame 1 to keep the sliding block 45 moving horizontally. The connecting block 53 is fixedly connected to the lower surface of the mounting base 2. When the bidirectional lead screw 52 rotates, the sliding connecting block 53 drives the mounting base 2 to move.

[0020] Reference Figure 2 , Figure 3 and Figure 4 The connecting plate 47 is fixedly connected to the end of the sliding rod 3 away from the mounting base 2, allowing the sliding rod 3 to drive the extension plate 46 to move through the connecting plate 47. The lower surface of the sliding frame 1 is equipped with moving wheels 6 for facilitating the movement of the device. The outer wall of the sliding rod 3 is rotatably connected to the support plate 7. The support plate 7 is used to ensure the stability of the support frame 41 when the support assembly 4 extends. The support plate 7 is fixedly connected to the upper surface of the sliding frame 1. The support plate 7 is attached to both ends of the support frame 41, and can also play the role of centering and stabilizing the support frame 41. There are two sets of extension plates 46. The two sets of extension plates 46 are symmetrically arranged with the center line of the rotating disk 43 as the axis of symmetry. After the adjustment mechanism extends, the symmetrically arranged extension plates 46 can support and fix both ends of the long workpiece. The upper surface of the extension plate 46 is provided with an arc-shaped protrusion that fits the edge of the rotating disk 43 but does not contact the rotating disk 43, so that the upper surface of the extension plate 46 is flush with the rotating disk 43. When the extension plate 46 is not used, the workpiece can be placed on the rotating disk 43 for work.

[0021] Working principle: In use, the drive motor 51 of the extension assembly 5 is started, which drives the bidirectional lead screw 52 to rotate. Since the bidirectional lead screw 52 is threadedly engaged with the two sets of connecting blocks 53, and the connecting blocks 53 are fixed to the bottom of the mounting base 2 and constrained by the sliding frame 1 to move horizontally, the two sets of mounting bases 2 slide synchronously towards or away from each other along the upper surface of the sliding frame 1, realizing precise adjustment of the distance between the mounting bases 2. This process can adapt to the clamping requirements of workpieces of different lengths. When the mounting base 2 moves, it drives the sliding rod 3 on its inner side to move synchronously. The sliding rod 3 pulls the extension plate 46 through the connecting plate 47 fixed at the end, so that the sliding block 45 at the bottom of the extension plate 46 slides laterally along the sliding groove 44 of the support frame 41. The sliding connection structure between the support frame 41 and the sliding rod 3 ensures that the extension plate 46 automatically extends as the distance between the mounting bases 2 increases, forming a continuous support plane. When processing short workpieces, the workpiece is placed directly on the upper surface of the rotating disk 43 and fixed by the external clamp. The drive motor 42 drives the rotating disk 43 to rotate, realizing multi-angle displacement welding of the workpiece. When long workpieces need to be processed and the distance between the mounting bases 2 needs to be increased, the extension plate 46 extends to both sides of the rotating disk 43. The two ends of the workpiece are respectively placed on the symmetrically arranged extension plates 46 and fixed by the clamping parts on the upper surface of the extension plate 46. The arc-shaped protrusion structure of the extension plate 46 fits with the edge of the rotating disk 43 to form a continuous support surface, realizing three-point positioning and fixing. The rotatable sliding rod 3 drives the entire support assembly 4 and the workpiece to rotate synchronously, completing the long workpiece flip welding displacement. The support plate 7 on the outer wall of the sliding rod 3 always fits against both ends of the support frame 41, providing radial constraint force when the support assembly 4 is extended, preventing the support frame 41 from shifting, and ensuring rigid support during the flipping process of the long workpiece. The moving wheel 6 provides the flexibility of the overall displacement of the device. After the extension plate 46 is retracted and reset, its surface remains flush with the rotating disk 43 and does not contact it, avoiding interference with the independent operation of short workpieces.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
