Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal welding technology, and in particular to a multi-station metal welding anti-deviation fixture. Background Technology
[0002] Metal welding is a permanent joining technique that uses heat, pressure, or both to bond separated metals together atomically. It is widely used in manufacturing, construction, aerospace, and other fields. Its core principle is to melt or plastically deform materials through energy input (thermal energy / pressure energy), which then cools to form a strong joint. It is currently one of the most commonly used joining methods in the metal processing field. In the manufacturing of certain complex metal structures, it is necessary to weld multiple components onto the same workpiece to achieve specific functions or structural strength requirements.
[0003] However, in existing technologies, when welding multiple parts onto the same workpiece, welding operators typically need to frequently adjust the workpiece's position and repeatedly loosen and tighten the clamps to weld different parts sequentially. This repetitive operation not only consumes a significant amount of time and effort, but also easily leads to welding position deviations due to the difficulty in ensuring completely consistent clamping positions and forces each time, affecting welding quality and product consistency. Furthermore, frequent operations increase the operator's workload and reduce production efficiency.
[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-station metal welding anti-deviation fixture.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a multi-station metal welding anti-deviation fixture, including a support plate, and further comprising:
[0007] Multiple mounting plates are provided, and the support plate has a sliding groove for the mounting plate to slide. The support plate is also provided with a locking mechanism for locking the mounting plate in the sliding groove.
[0008] Multiple part clamping mechanisms, each of which is mounted on a mounting plate and includes a fixed left clamp and a movable right clamp;
[0009] The drive assembly includes a drive rod that is driven to multiple right clamps, and an electric push rod that is connected to the drive rod to drive its movement. When the electric push rod drives the drive rod to move, it can synchronously drive multiple right clamps to move relative to their corresponding left clamps.
[0010] More specifically, a T-shaped groove is provided on the top of the support plate;
[0011] The locking mechanism includes a hand-tightening sleeve rotatably connected to the mounting plate, a screw rod threaded through the mounting plate and connected to the inner wall of the hand-tightening sleeve, and a limiting block rotatably connected to the lower end of the screw rod and accommodated in a T-groove. The limiting block slides vertically against the inner wall of the T-groove.
[0012] Preferably, it also includes a workpiece clamping mechanism disposed on the support plate, the workpiece clamping mechanism including a lower clamp fixedly connected to the support plate, a movable upper clamp, and a threaded rod threadedly connected to the upper clamp.
[0013] Furthermore, one end of the threaded rod is provided with a round shell, and the round shell is provided with a pluggable lever.
[0014] More specifically, each part clamping mechanism also includes a limiting bolt fixedly connected to the side wall of the right clamp, and the limiting bolt has two nuts threadedly connected to it.
[0015] Preferably, the drive assembly also includes a switch electrically connected to the electric actuator.
[0016] More specifically, anti-slip textures are provided on the opposing surfaces of the left and right clamps.
[0017] Preferably, the drive rod is slidably mounted on the support plate.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] By setting up multiple adjustable mounting plates within the chute, and incorporating a part clamping mechanism on each plate, and then using a unified drive assembly (drive rod and electric push rod) to synchronously control all part clamping mechanisms, this solution solves the technical problem of cumbersome and inefficient operation in existing technologies that require repeated positioning and clamping of workpieces and parts. This solution can complete the positioning and clamping of multiple parts at once, significantly improving the efficiency of welding multiple parts onto a single workpiece.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0027] In the field of metal processing, welding is widely used as an important joining technology. Especially when manufacturing complex structures, it is often necessary to weld multiple components onto the same workpiece. However, existing welding fixtures have significant limitations in handling this situation. Operators typically need to repeatedly adjust the workpiece position and perform individual clamping and releasing operations for each component to be welded. This manual, sequential process is not only inefficient, but also prone to component misalignment relative to the workpiece due to the difficulty in maintaining consistent clamping precision and force each time, thus affecting the final weld quality and product accuracy. This cumbersome and error-prone operation method urgently requires a solution that can improve efficiency while ensuring accuracy.
[0028] like Figures 1 to 5 The multi-station metal welding anti-deviation fixture shown includes a support plate 1, and also includes:
[0029] Multiple mounting plates 8, the support plate 1 is provided with a sliding groove 7 for the mounting plate 8 to slide, and the support plate 1 is also provided with a locking mechanism for locking the mounting plate 8 in the sliding groove 7;
[0030] Multiple part clamping mechanisms, each of which is mounted on a mounting plate 8 and includes a fixed left clamp 19 and a movable right clamp 18.
[0031] The drive assembly includes a drive rod 15 that is pulsatorically connected to a plurality of right clamps 18, and an electric push rod 17 connected to the drive rod 15 to drive its movement. When the electric push rod 17 drives the drive rod 15 to move, it can synchronously drive the plurality of right clamps 18 to move relative to their corresponding left clamps 19.
[0032] In practice, compared with the existing technology that requires manual clamping and positioning of each component individually, the multi-station metal welding anti-deviation fixture of this utility model has significant advantages. In the existing technology, each time a component is welded, the steps of positioning, clamping, welding, releasing, repositioning, and clamping are repeated, making the operation process complex and time-consuming. However, this utility model, by setting multiple adjustable mounting plates 8 and part clamping mechanisms, allows the operator to pre-adjust all clamping mechanisms to the corresponding positions of the components to be welded and lock them. More importantly, the synchronous driving of all right clamps 18 is achieved through the drive components (drive rod 15 and electric push rod 17), which can complete the clamping or release of all components at once. This synchronous operation greatly simplifies the operation process, reduces repetitive labor, and significantly improves welding efficiency. In addition, since multiple components are clamped simultaneously, it can effectively reduce the slight displacement of the relative positions of the components that may be caused by sequential operation during the clamping process, thereby improving the positioning accuracy of welding, reducing the risk of welding defects, and ensuring product quality. The clamping force provided by the electric push rod 17 is stable and controllable, further improving the reliability and consistency of clamping.
[0033] The complete process of welding multiple parts using the multi-station metal welding anti-offset fixture of this utility model is as follows: First, the main workpiece to be welded is placed on the support plate 1 and fixed (if the fixture includes a workpiece clamping mechanism, this mechanism is used to fix the workpiece). Then, according to the position of the parts to be welded on the main workpiece, each mounting plate 8 is slid along the slide groove 7 on the support plate 1 to the corresponding position. After adjusting the position, the locking mechanism is operated to firmly lock each mounting plate 8 in the slide groove 7, ensuring that its position no longer moves. Next, the parts to be welded are placed in the part clamping mechanism on each mounting plate 8, located between the left clamp 19 and the right clamp 18. At this time, the right clamp 18 is in the released position. Then, the electric push rod 17 is activated (e.g., by pressing the switch 16), and the electric push rod 17 begins to extend or retract, driving the drive rod 15 connected to it to move along its direction of movement. Since the drive rod 15 is connected to multiple right clamps 18, the movement of the drive rod 15 will synchronously drive all right clamps 18 to move relative to their corresponding left clamps 19. When the right clamp 18 moves to the position where it clamps the component with the left clamp 19, the movement of the electric push rod 17 stops. At this point, all components to be welded are simultaneously and securely clamped in the preset positions. The operator can then perform welding operations on all clamped components. After welding is completed, the electric push rod 17 is restarted to move in the opposite direction, driving the drive rod 15 to move in the opposite direction, thereby synchronously moving all right clamps 18 away from the left clamp 19, releasing the clamps on the components. Finally, the welded workpiece and components are removed.
[0034] In this process, the support plate 1 provides a stable working platform; the mounting plate 8 and the slide 7 provide flexible station adjustment capabilities; the locking mechanism ensures the stability of the station; the left clamp 19 and the right clamp 18 directly clamp the parts; the drive rod 15 realizes the linkage of multiple right clamps 18; and the electric push rod 17 provides the power and control for synchronous clamping / releasing. The entire system works in concert to achieve efficient and precise multi-part welding clamping, effectively solving the technical problems of cumbersome operation, low efficiency, and easy deviation in the prior art.
[0035] As one embodiment of this utility model, a T-shaped groove 12 is provided on the top of the support plate 1;
[0036] The locking mechanism includes a hand-tightening sleeve 9 rotatably connected to the mounting plate 8, a screw 10 passing through the mounting plate 8 and threadedly connected to the inner wall of the hand-tightening sleeve 9, and a limiting block 11 rotatably connected to the lower end of the screw 10 and accommodated in the T-groove 12. The limiting block 11 slides vertically against the inner wall of the T-groove 12.
[0037] In implementation, the T-slot 12 is a common guiding and fixing structure, with a cross-sectional shape resembling the letter "T," providing good stability and load-bearing capacity. The hand-tightening sleeve 9 is typically made of metal or plastic, and its outer surface can be designed with textures or protrusions for easy gripping and rotation by the operator. The screw 10 is threadedly connected to the hand-tightening sleeve 9, allowing the screw 10 to move up and down by rotating the sleeve. The shape and size of the limiting block 11 match the internal space of the T-slot 12, converting the vertical movement of the screw 10 into a clamping force on the mounting plate 8.
[0038] As one embodiment of this utility model, it also includes a workpiece clamping mechanism disposed on the support plate 1. The workpiece clamping mechanism includes a lower clamp 6 fixedly connected to the support plate 1, a movable upper clamp 5, and a threaded rod 4 threadedly connected to the upper clamp 5.
[0039] In practice, this workpiece clamping mechanism is designed to fix the main workpiece during welding, ensuring its stable position and providing a reliable reference for the precise positioning and welding of subsequent components. The lower clamp 6 is directly fixed to the support plate 1, serving as the workpiece's support surface. The upper clamp 5 is connected to the lower clamp 6 via a threaded rod 4. By rotating the threaded rod 4, the position of the upper clamp 5 relative to the lower clamp 6 can be adjusted to clamp workpieces of different sizes.
[0040] As one embodiment of this utility model, one end of the threaded rod 4 is provided with a round shell 3, and the round shell 3 is provided with a pluggable lever 2.
[0041] In implementation, to facilitate the operator's rotation of the threaded rod 4, this invention includes a circular shell 3 at one end of the threaded rod 4. The circular shell 3 can be made of metal or plastic, and its outer surface can be designed with textures or protrusions for easy gripping. More ingeniously, a removable lever 2 is also provided on the circular shell 3. Therefore, the design of the lever 2 greatly facilitates the operation of the workpiece clamping mechanism. Compared with the existing method of directly rotating the threaded rod 4, this design can utilize the lever 2 to provide greater torque for effortless clamping, and can also quickly adjust when no large torque is needed, improving operational flexibility and efficiency. As a preferred embodiment, the lever 2 can be telescopic for easy storage and carrying. In summary, the design of the lever 2 provides a more convenient, efficient, and effortless workpiece clamping operation solution for multi-station metal welding anti-deviation fixtures.
[0042] As one embodiment of this utility model, each part clamping mechanism also includes a limiting bolt 14 fixedly connected to the side wall of the right clamp 18, and two nuts 13 are threadedly connected to the limiting bolt 14.
[0043] In practice, to achieve precise adjustment of the position of each right clamp 18, a limiting bolt 14 is fixedly connected to each right clamp 18. This limiting bolt 14 can be set perpendicular to the clamping surface of the right clamp 18 and passes through a hole in the right clamp 18. Two nuts 13 are threaded onto the limiting bolt 14. By adjusting the position of these two nuts 13 on the limiting bolt 14, the position of the right clamp 18 relative to the drive rod 15 can be precisely adjusted, thereby achieving fine-tuning of the clamping force of the clamping mechanism for each part.
[0044] As one embodiment of the present invention, the drive assembly also includes a switch 16 electrically connected to the electric push rod 17.
[0045] The switch 16 can take various forms, such as a push-button switch, a toggle switch, or a rotary switch. The switch 16 is typically mounted on the side or top of the support plate 1 for easy operator access. The switch 16 is connected to the electric actuator 17 via a wire, which can be concealed inside or outside the support plate 1. As a preferred embodiment, the switch 16 can employ a self-locking design, meaning that when the switch is pressed, the electric actuator 17 continues to move; when the switch is pressed again, the electric actuator 17 stops moving.
[0046] As one embodiment of this utility model, anti-slip textures are provided on the opposing surfaces of the left clamp 19 and the right clamp 18.
[0047] Anti-slip textures can take various forms, such as serrated, mesh, or granular textures. The material of the anti-slip texture can be the same as the clamping part, or it can be a material with a higher coefficient of friction, such as rubber or plastic. The anti-slip texture can be formed by methods such as machining, chemical etching, or laser etching. As a preferred embodiment, the anti-slip texture can be designed to be replaceable, allowing for easy replacement according to the shape and size of different parts.
[0048] Therefore, the anti-slip texture design provides a more stable part clamping solution for multi-station metal welding anti-deviation fixtures. Compared with the smooth clamping surface used in existing technologies, this design can effectively prevent parts from sliding or shifting during clamping and welding, thereby improving welding positioning accuracy and ensuring product quality. In conclusion, the anti-slip texture design provides a more reliable, accurate, and safe part clamping solution for multi-station metal welding anti-deviation fixtures.
[0049] In one embodiment of this utility model, the drive rod 15 is slidably mounted on the support plate 1.
[0050] The design of the drive rod 15 slidingly mounted on the support plate 1 provides a more stable and low-resistance power transmission solution for the multi-station metal welding anti-deviation fixture. Compared with the fixed or hinged connections used in the prior art, this design can effectively reduce the vibration and noise generated by the drive rod 15 during movement, thereby ensuring the smoothness and consistency of the synchronous movement of multiple right clamps 18. In summary, the design of the drive rod 15 slidingly mounted on the support plate 1 provides a more reliable, efficient, and quiet power transmission solution for the multi-station metal welding anti-deviation fixture.
[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
