Description

Technical Field

[0001] This utility model belongs to the field of welding positioning technology, and specifically relates to a welding positioning fixture. Background Technology

[0002] Welding positioning fixtures are process equipment used to accurately position and firmly clamp workpieces during welding. They constrain the spatial position of the workpiece through positioning elements and prevent displacement during welding with the help of clamping mechanisms, ensuring the relative position of the parts to be welded is accurate, guaranteeing the dimensional accuracy of the welded joint and the consistency of assembly, improving welding quality and production efficiency. They are widely used in welding scenarios such as machinery manufacturing and are an important tool for achieving standardized and automated welding.

[0003] However, while traditional welding positioning fixtures can constrain workpieces, they have significant shortcomings in the adjustment and positioning of interface welding. When precise alignment of the welding interface of two workpieces is required, their fixed structure is often difficult to quickly adapt to the adjustment requirements of different angles and spacings. They often rely on manual disassembly and assembly or the use of additional tools to assist in positioning. This not only makes the operation process cumbersome and time-consuming, but also easily leads to interface alignment deviations due to insufficient adjustment accuracy. In actual use, they have exposed problems such as lack of flexibility and low adaptation efficiency, making it difficult to meet the convenience requirements of efficient welding operations.

[0004] To address the aforementioned issues, this application proposes a welding positioning fixture. Utility Model Content

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

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a welding positioning fixture, comprising a base plate 1, two slotted frames 2 fixedly connected to the upper surface of the base plate 1, a sliding frame 10 slidably connected inside each slotted frame 2, a threaded rod 9 rotatably connected to the inner wall of each slotted frame 2, and the outer surface of each threaded rod 9 threadedly connected to the inner wall of the sliding frame 10. A controller 6 and two brake motors 7 are respectively arranged above the base plate 1. The output end of each brake motor 7 is fixedly connected to the left end of the threaded rod 9. Two sets of first electric push rods 13 are fixedly connected to the upper surface of each sliding frame 10. A support plate 12 is fixedly connected to the telescopic end of each set of first electric push rods 13. Two second electric push rods 17 are arranged above each support plate 12. A positioning ring 15 is fixedly connected to the telescopic end of each second electric push rod 17.

[0024] In this embodiment, the controller 6 is a programmable logic controller (PLC), which has high stability and flexible program setting functions. It can accurately control the equipment operating parameters and coordinate the operation of each component. At the same time, the brake motor 7 adopts an electromagnetic braking three-phase asynchronous motor. Its instant braking characteristic when power is cut off ensures accurate positioning and avoids displacement deviation caused by inertia. The first electric push rod 13 and the second electric push rod 17 are both servo electric push rods. Through the closed-loop control system, they can achieve millimeter-level precision extension and retraction adjustment and have load self-adaptation capability. They can stably drive the support plate 12 and the positioning ring 15 to complete the efficient positioning and clamping of workpieces of different weights.

[0025] Specifically, two sets of fixing pins 4 are provided on the top of the base plate 1. The bottom end of each fixing pin 4 passes through the base plate 1 and extends to the bottom of the base plate 1. In this embodiment, the base plate 1 is fastened to the workbench or ground by fixing pins 4 to prevent the tooling from shifting during welding operations and to ensure positioning stability.

[0026] Specifically, a connecting plate 5 is fixedly connected to the bottom surface of the controller 6. The bottom surface of the connecting plate 5 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the controller 6 and the base plate 1 are stably assembled through the connecting plate 5, which not only ensures that the controller 6 is installed firmly, but also facilitates disassembly and assembly operations during later inspection and maintenance.

[0027] Specifically, two protective shells 3 are fixedly connected to the upper surface of the base plate 1. Each protective shell 3 is fitted over the outside of the brake motor 7. In this embodiment, the protective shells 3 provide physical protection for the brake motor 7, preventing damage to the motor from welding spatter, dust and external impacts, and extending its service life.

[0028] Specifically, each brake motor 7 has a support base 8 fixedly connected to its bottom surface, and the bottom surface of each support base 8 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the support base 8 raises the installation height of the brake motor 7, reduces the interference of debris on the surface of the base plate 1 on the operation of the motor, and enhances the structural strength of the connection between the motor and the base plate 1.

[0029] Specifically, a reinforcing ring 11 is fixedly connected to the outer surface of each first electric push rod 13, and the bottom surface of each reinforcing ring 11 is fixedly connected to the upper surface of the sliding frame 10. In this embodiment, the reinforcing ring 11 further strengthens the connection rigidity between the first electric push rod 13 and the sliding frame 10, prevents the push rod from shaking due to force when it extends or retracts, and ensures the height adjustment accuracy.

[0030] Specifically, each second electric push rod 17 has a fixed frame 14 fixedly connected to its outer surface, and the bottom surface of each fixed frame 14 is fixedly connected to the upper surface of the support plate 12. In this embodiment, the fixed frame 14 provides stable support for the second electric push rod 17, improves its torque resistance when clamping the workpiece, and avoids affecting the alignment accuracy of the positioning ring 15 due to deformation under force.

[0031] Specifically, each set of positioning rings 15 has a protective ring 16 fixedly connected to one side of each other. Each protective ring 16 is made of rubber. In this embodiment, the rubber protective ring 16 directly contacts the workpiece surface, which can avoid scratches on the workpiece caused by hard contact, and can also use the elasticity of rubber to enhance the clamping friction and prevent the workpiece from loosening and shifting during the welding process.

[0032] The working principle and usage process of this utility model are as follows: First, the base plate 1 is fixed to the worktable using the fixing pin 4 to ensure the overall stability of the fixture. The workpiece to be welded is placed on the support plate 12. The controller 6 activates the second electric push rod 17, whose telescopic end drives the positioning ring 15 to move towards the workpiece. The elasticity of the rubber protective ring 16 clamps the workpiece, preventing surface scratches while providing stable friction. If the workpiece height needs to be adjusted, the controller 6 controls the extension and retraction of the first electric push rod 13, causing the support plate 12 to move vertically, adapting to the height requirements of different welding positions. When it is necessary to adjust the height of two workpieces... When the lateral spacing is adjusted, the brake motor 7 is started to rotate forward or in reverse. The output end of the motor drives the threaded rod 9 to rotate, and the sliding frame 10 slides smoothly in the slot frame 2 through the threaded transmission until the workpiece interface reaches the preset position. The electromagnetic braking function of the brake motor 7 can lock immediately after positioning to prevent displacement. During the welding process, the protective shell 3 can block the damage to the motor by the spatter. The reinforcing ring 11 and the fixed frame 14 respectively enhance the connection rigidity of the electric push rod to ensure adjustment accuracy. The entire tooling is controlled by the PLC controller 6 to realize the coordinated operation of each component, complete the automated positioning and clamping of the workpiece, and greatly improve the welding efficiency and positioning accuracy.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
