Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding fixture and production line. Background Technology

[0002] In the automotive manufacturing industry, the fuel filler cap is a key component of the fuel supply system, and its structural integrity and connection strength directly affect the vehicle's fuel safety and reliability. The fuel filler cap typically consists of a filler cap body and a spiral body; their effective connection is crucial for ensuring the component's functionality, and fusion welding is the primary technical means to achieve this connection.

[0003] Currently, the fusion welding process between the fuel filler nozzle body and the spiral body in the industry mainly relies on manual operation. Operators need to manually position and align the fuel filler nozzle body and the spiral body, and then use a handheld heating tool to locally heat the connection area of ​​the two workpieces. After the heated area reaches the preset fusion temperature, pressure is applied to force the molten parts of the two workpieces to bond together, thus completing the welding operation.

[0004] However, manual welding has many limitations in practical applications: First, heating accuracy is difficult to guarantee. When manually holding the heating tool, the heating position, temperature, and time all depend on the operator's experience and judgment, which is easily affected by the stability of human operation. This can lead to insufficient heating uniformity at the joint of the two workpieces, with some areas potentially suffering material degradation due to overheating or incomplete fusion due to underheating, directly affecting the welding quality. Second, production efficiency is low. The manual operation process is cumbersome, and each welding step is time-consuming, making it difficult to achieve continuous and batch production, which cannot meet the high-efficiency production needs of the modern automotive manufacturing industry. Third, quality stability is poor. Different operators have different skill levels and operating habits, and even the same operator's condition may fluctuate at different times, resulting in poor welding quality consistency for the same batch of products, increasing subsequent quality inspection costs and product defect rates. Fourth, the labor intensity is high and there are safety hazards. Operators are in a high-temperature working environment for a long time, performing repetitive operations while holding heating tools. This not only results in high labor intensity but also poses safety risks such as burns, which does not meet the requirements of modern manufacturing for a safe and humane working environment.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0020] Example 1, refer to Figures 1-6 As shown, a welding fixture of this utility model includes, The first fixing component 1 includes a first base plate 11, a first fixing seat 12, and a telescopic drive source 13. The first base plate 11 is horizontally arranged, and a plurality of first fixing seats 12 are provided at the bottom of the first base plate 11. Each first fixing seat 12 has a first receiving groove 121 at the bottom and a through hole 122 communicating with the first receiving groove 121 on the side. A plurality of telescopic drive sources 13 are provided. The plurality of telescopic drive sources 13 are all connected to the bottom of the first base plate 11 and are respectively located on one side of each first fixing seat 12. The output end of each telescopic drive source 13 faces the first fixing seat 12 it is close to and is equipped with a pressure block 131 corresponding to the position of the through hole 122 thereon. The second fixing component 2 includes a second base plate 21 and a second fixing seat 22. The second base plate 21 is horizontally disposed directly below the first base plate 11. The top of the second base plate 21 is provided with a plurality of second fixing seats 22 corresponding to the positions of each first fixing seat 12. Each second fixing seat 22 is provided with a second receiving groove 221. Heating assembly 3 includes a third substrate 31 and heating elements 32. The third substrate 31 is horizontally disposed between the first substrate 11 and the second substrate 21. The top and bottom of the third substrate 31 are provided with a plurality of heating elements 32 corresponding to the positions of the first fixing seat 12 and the second fixing seat 22, respectively.

[0021] Specifically, the first receiving groove 121 is used to place the spiral body. When the spiral body is placed in the first receiving groove 121, the telescopic end of the corresponding telescopic drive source 13 extends, and the drive pressure block 131 passes through the through hole 122 on the corresponding first fixing seat 12 and presses the spiral body to fix it. The second receiving groove 221 is used to place the oil filling port body. After the oil filling port body is placed in the second receiving groove 221, it is fixed by the vacuum suction cup 23. The multiple heating elements 32 provided on both sides of the third substrate 31 are used to heat the welding position of the corresponding spiral body and oil filling port body.

[0022] This utility model discloses a welding fixture that can automatically position and fix two workpieces to be welded, and can automatically heat melt and butt weld the workpieces. Compared with manual operation, it has higher positional accuracy and efficiency, which not only helps to improve the final quality of the product, but also reduces the production cost and reduces the possibility of safety accidents during the production process.

[0023] Reference Figure 4 and Figure 5 As shown, further, a plurality of mounting holes are provided on the top end face of the second fixing base 22, and a vacuum suction cup 23 is provided in each mounting hole. A plurality of air holes are provided on the side of the second fixing base 22, which are connected to each mounting hole. A connector 24 is provided on each air hole, and a vacuum generator is connected to the connector 24.

[0024] Reference Figure 6 As shown, the third substrate 31 is further provided with multiple mounting seats, and each heating element 32 is connected to each mounting seat by multiple support feet.

[0025] Furthermore, the heating element 32 is a heating plate. More preferably, the position to be heated on the spiral body is at its end face, so the heating element 32 corresponding to the first fixing seat 12 directly uses a heating plate, and the heating plate surface directly contacts the end face of the spiral body for heat melting; the heating position of the oil filler body is on a step surface in its inner hole, which cannot be directly heated by a heating plate, so the heating element 32 corresponding to the second fixing seat 22 adopts a composite structure of heating plate and cylindrical component, using the heating plate to heat the cylinder, and the cylinder to heat the heat melting position in the inner hole of the oil filler body.

[0026] Furthermore, the first substrate 11 and the second substrate 21 are connected to a first drive mechanism for driving them to move in the vertical direction.

[0027] Furthermore, the third substrate 31 is connected to a second drive mechanism for driving its movement in the horizontal direction.

[0028] Reference Figure 2 and Figure 3As shown, the first fixed seat 12 further includes a first positioning groove 123 communicating with the first receiving groove 121, and the second fixed seat 22 includes a second positioning groove 222 communicating with the second receiving groove 221. Specifically, a protrusion is provided on the side of the spiral body, and a protruding connecting component is provided on the side of the oil filler body. Therefore, in designing the first fixed seat 12 and the second fixed seat 22, the external features of the spiral body and the oil filler body are fully utilized, and positioning grooves (i.e., the first positioning groove 123 and the second positioning groove 222) are respectively provided on the first fixed seat 12 and the second fixed seat 22 to cooperate with the protrusion and the connecting component. This serves to prevent mistaken identity, facilitates operation by workers, and helps improve welding efficiency.

[0029] Furthermore, the free end of the pressure block 131 is provided with an arc surface. It can be imagined that since the spiral body is cylindrical in shape, providing an arc surface at the free end of the pressure block 131 can increase the contact area between the pressure block 131 and the spiral body, thereby ensuring that the spiral body is compressed.

[0030] Furthermore, the telescopic drive source 13 adopts a pneumatic cylinder or an electric cylinder.

[0031] Working process: First, a spiral body is placed into the first receiving groove 121 of each first fixed seat 12. Then, the output shaft of the telescopic drive source 13 is extended to press and fix the spiral body. At the same time, a filler body is placed into the second receiving groove 221 of each second fixed seat 22 and fixed by the vacuum suction cup 23. Then, the drive mechanism drives the first substrate 11 and the second substrate 21 to move towards each other until the heating elements 32 on both sides of the third substrate 31 contact the welding position of the corresponding spiral body or filler body. The heating elements 32 heat the welding position at a predetermined temperature. After heating to the predetermined temperature, the drive mechanism drives the first substrate 11 and the second substrate 21 to move a predetermined distance away from each other. Then, the drive mechanism drives the third substrate 31 to move laterally and move out from between the first substrate 11 and the second substrate 21. Then, the drive mechanism drives the first substrate 11 and the second substrate 21 to move towards each other so that the corresponding spiral body and filler body are joined together for fusion welding. After welding is completed, each telescopic drive source 13 is reset and releases the spiral body. At the same time, the drive mechanism drives the first substrate 11 and the second substrate 21 to reset.

[0032] Example 2: This utility model also discloses a production line, including the welding fixture as in Example 1.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
