Description

Technical Field

[0001] This invention belongs to the field of welding technology for filling pump components, specifically relating to a welding fixture for an adjustable-height and movable filling pump S-tube. Background Technology

[0002] The S-tube assembly in an S-valve filling pump plays a crucial role in reversing and material conveying. Particularly during reversing, it is essential to ensure a high degree of concentricity between the S-tube, the spectacle plate at the pump outlet, and the piston cylinder outlet. However, in actual welding, the complex structure and significant weight of the S-tube assembly make riveting difficult, easily leading to uncontrollable dimensional deviations. Simultaneously, thermal shrinkage and deformation during welding can cause overall structural deformation, affecting dimensional accuracy. These issues make it difficult to guarantee the coaxiality of the S-tube assembly during subsequent machining, ultimately resulting in defective products and severely impacting the pumping flow rate and performance of the filling pump.

[0003] Currently, welding operations mostly rely on traditional fixtures or simple tooling to position and fix the workpiece. However, traditional fixtures usually lack flexibility and cannot adapt to workpieces of different sizes or shapes. Furthermore, due to the effects of thermal deformation during welding, the workpiece is prone to displacement or deformation, further affecting the welding quality. In addition, manually adjusting the fixing device is not only time-consuming and labor-intensive, but also reduces production efficiency.

[0004] Existing welding fixtures are usually fixed to the workbench and cannot be moved. Especially in confined working environments (such as in high temperatures in summer), such fixed fixtures can easily cause safety hazards such as suffocation and heatstroke. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the prior art and provide a height-adjustable and movable welding fixture for the S-tube of a filling pump.

[0006] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0007] The adjustable height movable filling pump S-tube welding fixture includes a fixture base (6), the bottom of which is provided with wheels; one end of the fixture base (6) is provided with a lifting bracket (3) and the other end is provided with a wear-resistant sleeve fixing device (5); a V-shaped seat lifting bracket (4) is provided on the fixture base (6) near the lifting bracket (3); a three-jaw chuck base (2) is provided on the lifting bracket (3), and a three-jaw chuck (1) is provided on the three-jaw chuck base (2).

[0008] Preferably, the adjustable height movable filling pump S-tube welding fixture also includes servo motors connected to the lifting bracket (3) and the V-shaped seat lifting bracket (4), respectively.

[0009] Preferably, the adjustable height movable filling pump S-tube welding fixture also includes a servo motor connected to a three-jaw chuck (1).

[0010] Preferably, the three-jaw chuck (1) is a K11-630 three-jaw chuck.

[0011] The invention will be further explained below in conjunction with its usage:

[0012] The welding fixture for the filling pump S-tube of this invention consists of six main components. The filling pump S-tube comprises a ring sleeve, an S-tube, a wear-resistant sleeve, and a V-shaped seat. In use, firstly, the ring sleeve 7 is clamped using a three-jaw chuck 1. Depending on the model of the filling pump S-tube, the height of the lifting bracket 3 is adjusted to ensure the alignment accuracy of each component during welding. After adjusting the lifting bracket, the three-jaw chuck base 2 is connected and fixed to the fixture base 6 with high-strength bolts to ensure overall structural stability. As needed, the height of the V-shaped seat bracket 4 is adjusted, and the S-tube 8 is placed on it, with the V-shaped seat positioned on the V-shaped seat bracket 4. The position of the wear-resistant sleeve fixing device 5 is adjusted to ensure the stability of the wear-resistant sleeve 9, and then fixed with a fastening device. After completing the above preparations, welding operations can be performed. When the lifting bracket 3 and V-shaped seat bracket 4 are adjusted using a servo motor lead screw, the fixture can automatically adjust the height of the filling pump S-tube through the accompanying operating program. This design allows the fixture to adapt to different specifications and models of filling pump S-tubes and achieves a semi-automated welding process, improving production efficiency.

[0013] 1. Rapid positioning and clamping to ensure coaxiality control: It can achieve rapid workpiece positioning and clamping, effectively ensuring the coaxiality requirements of the filling pump S-tube and its components, avoiding dimensional errors caused by workpiece displacement or inaccurate positioning during welding, thereby improving welding quality.

[0014] 2. Preventing workpiece deformation and displacement: Through precise clamping and a stable fixing structure, this fixture can effectively prevent workpiece displacement or deformation caused by thermal deformation and welding stress during the welding process, ensuring the stability and consistency of geometric dimensions during the welding process.

[0015] 3. Adaptable to different specifications and models, reducing the number of tooling: This welding tooling is flexibly designed and can adapt to different specifications and models of filling pump S-tubes, reducing the dependence on multiple different tooling, saving production costs and improving the efficiency of tooling use.

[0016] 4. Movable design enhances production flexibility: The tooling is equipped with movable steel wheels at the bottom, which can easily move the entire tooling. Especially in narrow spaces or when frequent adjustments to the work position are required, it provides great flexibility and ease of operation, avoiding production problems caused by fixed workstation restrictions.

[0017] 5. Significantly reduces production time and costs: After testing and production use, it was found that using this tooling significantly shortens the riveting and welding positioning time, avoiding manual adjustment and multiple trial debugging. Welding efficiency is improved, and the production cycle is shortened.

[0018] 6. Significantly improved product qualification rate: Comparative analysis with products welded using the old tooling revealed that the product qualification rate significantly increased from 60% to 100% after adopting this welding tooling. This improvement significantly enhanced production efficiency and product quality while reducing rework rates.

[0019] In summary, by using this invention, manufacturers can significantly improve production efficiency and reduce production costs while ensuring welding accuracy. Compared with traditional welding fixtures, this fixture design is more adaptable and can meet the welding requirements of different S-tube models, reducing the number of fixtures and improving the flexibility of the production line. Ultimately, production quality is guaranteed, and the product qualification rate is increased to 100%. Attached Figure Description
