Description

TECHNICAL FIELD

[0001] The utility model belongs to condenser frock technical field relates to a condenser welding frock. BACKGROUND

[0002] As the core component in refrigeration system, the precision and efficiency of welding process in the manufacturing process of condenser directly affect the performance and service life of the product. In the existing condenser production process, welding frock is widely used to fix the condenser body and its support, to ensure the position accuracy and firm connection of the welding part. The traditional condenser welding frock usually adopts manual operation mode, and its process flow is generally as follows: the operator first places the condenser product on the bottom plate of the frock, then places multiple supports on the corresponding support mounting seat, and then manually tightens the product positioning quick clamp and support positioning quick clamp one by one, and finally welds the connecting part of all supports and condenser. Although this method can complete the basic welding task, it exposes many problems in actual production, which limits the improvement of production efficiency and the stability of product quality.

[0003] Specifically, the traditional condenser welding frock has the following significant shortcomings: first, the positioning of each support needs to be manually pressed by the operator. This operation method not only takes a long time, but also requires high proficiency of the operator. In mass production, the low efficiency of manual operation becomes an important bottleneck restricting the production capacity. For example, a condenser may need to install multiple supports, and each support needs to be adjusted and pressed independently, which significantly prolongs the completion time of the whole process. Secondly, the quick clamp pressing mechanism usually adopts a screw rod structure. Due to long-term use or improper operation, the screw rod is prone to looseness, which causes the stroke of the quick clamp to change. This instability of stroke directly affects the positioning accuracy of the condenser and the support, and ultimately leads to poor consistency of the product after welding. For example, when some supports are not firmly fixed, the welding process may deviate or appear virtual welding phenomenon, thereby reducing the product qualification rate. In addition, manual operation also has certain safety hazards. During the repeated pressing of the quick clamp, the operator is prone to fatigue or mistakes, which affects the stability of the frock.

[0004] From the perspective of technical development, with the continuous improvement of industrial automation level, the traditional manual welding tooling has been difficult to meet the demand of modern manufacturing for high efficiency and high precision production. In the field of condenser manufacturing, market competition is becoming increasingly fierce, and enterprises need to shorten the production cycle as much as possible and reduce labor costs on the premise of ensuring product quality. Therefore, improving the design of condenser welding tooling and reducing the dependence on manual operation have become the technical problems to be solved at present. In recent years, although some automated welding equipment has been introduced into condenser production, these equipment often has high cost and limited scope of application, and it is difficult to completely replace the traditional tooling design. For example, although some automated welding robots can realize rapid welding, they have high requirements for tooling cooperation, and if the positioning efficiency of the tooling itself is low, the advantages of automated equipment cannot be fully utilized. In addition, in the existing tooling design, the application of pneumatic or electric positioning devices is not common, especially in small and medium-sized enterprises, manual tooling still occupies a dominant position. This further highlights the necessity of developing a condenser welding tooling with simple structure, convenient operation and controllable cost. Practical new type content

[0026] Please refer to Figs. 1-3 The embodiment provides a condenser welding tool for welding and positioning of the condenser 1 and the condenser support 2, which comprises a bottom plate 3, a support mounting seat 6, a condenser positioning cylinder 5, a support positioning cylinder 4, a first cylinder switch valve 7 and a second cylinder switch valve 8.

[0027] In actual implementation, first, the condenser 1 is placed on the bottom plate 3. The bottom plate 3 is provided with four condenser supports 10, which are respectively located at the four corners of the condenser 1. Each condenser support 10 is provided with a positioning groove, and the two side edges of the condenser 1 are embedded in the positioning groove to achieve preliminary positioning. The condenser positioning cylinder 5 is fixed to the end side of the positioning groove. In this embodiment, one condenser positioning cylinder 5 is arranged on each of the left and right sides of the condenser 1. Then, the condenser support 2 is placed on the support mounting seat 6, and the support mounting seat 6 is fixed to the two sides of the condenser 1. Each side is provided with a plurality of support mounting seats 6 to adapt to a plurality of condenser supports 2. Each condenser support 2 is provided with a support positioning cylinder 4 on one side. In this embodiment, each condenser support 2 is clamped by three support positioning cylinders 4 to enhance the positioning stability.

[0028] The operator manually opens the first cylinder switch valve 7, and the condenser positioning cylinder 5 receives the air pressure signal through the air pipe. The left and right condenser positioning cylinders 5 are simultaneously extended to push the condenser 1 to tightly fit the positioning groove, and the clamping positioning of the condenser 1 is completed. Then, the operator opens the second cylinder switch valve 8, and all the support positioning cylinders 4 simultaneously act, extend and tightly press the condenser support 2, so that it is firmly fixed on the support mounting seat 6. The first cylinder switch valve 7 and the second cylinder switch valve 8 are both manual valves, which are installed on the edge of the bottom plate 3 for easy operation. After clamping is completed, the welding equipment is used to weld the connection part of the condenser support 2 and the condenser 1. After welding is completed, the first cylinder switch valve 7 and the second cylinder switch valve 8 are closed, and the condenser positioning cylinder 5 and the support positioning cylinder 4 are reset to release the clamping state, and the welded condenser product is removed.

[0029] In order to improve the durability and aesthetics of the tool, in this embodiment, the bottom plate 3 is provided with an air pipe channel 9, and all air pipes connected to the condenser positioning cylinder 5 and the support positioning cylinder 4 are pre-buried in the air pipe channel 9, and a cover plate is covered above the channel to avoid the air pipes being exposed to the outside and being damaged by the outside. In addition, the middle of the bottom plate 3 is designed as a hollow structure, which not only reduces the overall weight of the tool, but also facilitates heat dissipation during welding.

[0030] In this embodiment, the cylinder positioning system replaces the traditional manual quick clamp, which significantly improves the clamping efficiency and positioning accuracy. For example, in actual testing, the traditional manual tool takes about 2 minutes to complete the support clamping of one condenser, while the tool only takes about 30 seconds to complete all clamping operations. At the same time, the synchronous action of multiple cylinders ensures the positional consistency of the condenser and the condenser support, and the welding qualification rate is improved. The tool has a simple structure and is easy to operate, and is particularly suitable for mass production of condensers, and has high practical value.

[0031] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
