[0002] During the welding process, the main function of the welding fixture is to position and fix the welding product to facilitate precise welding. For workpieces with complex shapes or those requiring specific welding angles, adjustable pressure automatic welding fixtures can ensure that the workpiece maintains the correct posture throughout the welding process, enabling the welding operation to be performed according to design requirements and further improving welding accuracy.

[0003] In welding production, the inability to adjust the pressure of the welding product can lead to uneven force applied to the workpiece during the welding process, thus affecting the quality. Appropriate pressure can ensure full contact between the solder and the substrate, promoting good metallurgical bonding. Therefore, an automatic welding fixture with adjustable pressure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic welding fixture with adjustable pressure, which aims to improve the problem that the pressure on the welded products cannot be adjusted in the prior art.

A T-slot 4 is formed on the top of the support block 3, providing a sliding trajectory for the pressure power source. A cylinder 5 is fixedly connected to the front end of the pressure block 2, serving as the driving source for the pressure application action. A slider 6 is fixedly connected to the drive end of cylinder 5. The slider 6 is designed to transmit the pressure. The outside of the slider 6 is slidably connected to the inside of the T-slot 4. The bottom of the slider 6 is slidably connected to the top of the support block 3. Rotary shafts 7 are rotatably connected to both sides of the slider 6. The rotary shafts 7 are designed to transmit power. A clamping shaft block 8 is rotatably connected inside the pressure block 2.

A clamping component is fixedly connected to the bottom of the worktable 1 for clamping and positioning to prevent the welded product from shifting during automatic welding. A pushing component is fixedly connected to the rear end of the worktable 1 for preventing accidental damage to the welded product by human placement.

[0033] Reference Figure 1 , Figure 3 The clamping assembly includes a motor 9, which serves as the power source for the clamping action. The top of the motor 9 is fixedly connected to the bottom of the worktable 1. A rotating arm 10 is fixedly connected to the drive end of the motor 9. The rotating arm 10 acts as a bridge, ensuring that the power can be effectively transmitted and converted into the required mechanical motion. The top of the rotating arm 10 is rotatably connected to the bottom of the worktable 1, and two rotating shafts 11 are rotatably connected to the bottom of the rotating arm 10. The rotating shafts 11 are designed to convert rotational motion into linear motion. A positioning block 12 is fixedly connected to the top of the worktable 1. The positioning block 12 is designed to perform clamping motion. Multiple sliding grooves 13 are provided inside the worktable 1. The sliding grooves 13 are designed to guide the sliding of the positioning block 12. The outside of the positioning block 12 is slidably connected to the inside of the worktable 1. The outside of the positioning block 12 is slidably connected to the inside of two sliding grooves 13. A clamping block 14 is fixedly connected to the top of the positioning block 12. The clamping block 14 is designed to directly clamp the welding product. The bottom of the clamping block 14 is slidably connected to the top of the worktable 1.

[0034] Reference Figure 1 , Figure 4The pushing component includes a second cylinder 15, which serves as the power source for pushing. The front end of the second cylinder 15 is fixedly connected to the rear end of the worktable 1. A concave block 16 is fixedly connected to the driving end of the second cylinder 15, serving as the connection for power transmission. A rotating block 17 is fixedly connected inside the concave block 16, which serves as the conversion of mechanical motion. A support arm 18 is rotatably connected to the outside of the rotating block 17, providing structural support. The front end of the support arm 18 is fixedly connected to the rear end of the worktable 1. A rocking shaft 19 is fixedly connected to the outside of the rotating block 17, serving as the power transmission shaft. A T-shaped arm 20 is rotatably connected inside the rocking shaft 19, pushing the welding product. Blocks 21 are slidably connected to both sides of the T-shaped arm 20 to prevent the welding product from deviating during pushing. The bottoms of the two blocks 21 are fixedly connected to the top of the worktable 1.

[0035] Working Principle: When the product to be welded needs to remain stable during the welding process, and the pressure on the product needs to be adjusted, the drive end of cylinder 5 drives the slider 6 to slide within the T-groove 4 on top of the support block 3. This causes the rotating shafts 7 on both sides of the slider 6 to rotate. The clamping block 8, connected to the two rotating shafts 7, receives power from the drive end and, in conjunction with the rotating connection of the pressure block 2, generates a lever effect, pressing the product to be welded on top of the worktable 1 from the bottom. This design ensures the stability and precision of the workpiece during welding, thereby improving welding quality and efficiency. By using an adjustable-pressure automatic welding fixture, the operator can adjust the pressure according to the size and shape of different products to adapt to different welding needs. This flexibility allows the equipment to handle various types of welding tasks, thus increasing its application range and practicality.

[0036] When it is necessary to clamp the welding product to prevent misalignment and subsequent welding errors, the motor 9 is started to drive the rotating arm 10 to rotate. The rotating arm 10 drives the rotating shafts 11 connected on both sides to rotate. As the rotating shafts 11 rotate, they drag the connected positioning blocks 12, causing the two positioning blocks 12 to slide relative to each other in the multiple sliding grooves 13 inside the worktable 1. The two clamping blocks 14 on the top of the two positioning blocks 12 slide relative to each other on the top of the worktable 1, clamping the welding product placed on the top of the worktable 1. This ensures that the welding product is centered and does not deviate at all. In this way, the welding accuracy will be greatly improved during the welding operation, ensuring that the quality of the welded product is more reliable and meets high production standards.

[0037] If the welding product is placed manually during the welding process, it is easy to be accidentally injured. When it is necessary to prevent accidental injury from the placement of the welding product, place the welding product on the top of the workbench 1, with the two blocking blocks 21 facing each other. At this time, start the cylinder 15, and the drive end pushes the concave block 16. The rotating block 17, supported by the support arm 18, receives the pushing force from the concave block 16 and begins to rotate towards the front end, driving the external rocking shaft 19 to rotate and apply a pushing force to the T-shaped arm 20. The T-shaped arm 20 pushes the welding product placed between the two blocking blocks 21 to contact the rear end of the pressure block 2. Through this series of actions, the welding product is safely placed in a suitable position, away from the dangerous area in the welding process. This process not only improves the safety of the operator, but also provides convenience for subsequent welding operations, ensuring that the welding work can be carried out efficiently and safely.

[0038] 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.
