Description

Technical Field

[0001] This invention relates to the field of antifreeze plug assembly technology, and more specifically to an assembly auxiliary device for the production of antifreeze plugs. Background Technology

[0002] When the temperature drops below 0°C, water transforms from a liquid into solid ice. Once water freezes, it not only ceases to flow but also, due to its increased volume, often damages pipes (including equipment). Valve Pipes and fittings may crack due to expansion (commonly known as frost cracking). In northern my country, where winters are quite cold, special attention must be paid to insulation and frost protection. Using antifreeze plugs is one solution. Antifreeze plugs ensure that there is no residual water in pipes exposed outdoors, thus preventing freezing.

[0003] The working principle of the antifreeze hydrant is as follows: When using the antifreeze hydrant in winter, open the valve connected to the water storage tank, and use the key with a handwheel to operate the valve in the well. After the valve is opened, water will appear in the water pipe on the ground; closing the valve will stop the water flow in the pipe; at this time, the remaining water in the pipe will automatically flow into the water storage tank. When the valve in the well is opened again, the water in the storage tank will be drawn into the water pipe by the nozzle and flow upward with the water flow; when the valve is closed again, the remaining water in the pipe will be stored in the water storage tank. Since there is no possibility of water accumulation in the pipe section exposed outside the well, the water pipe will not freeze.

[0004] The antifreeze plug consists of multiple components. During the manufacturing process of the antifreeze plug, each component is produced in batches in the workshop. These components typically include two half-cylinders, valve disc, valve plate, upper and lower mounting plates, rotating shaft, filter tank and direct current cylinder, etc. After these components are processed, they need to be assembled and fixed to obtain a complete antifreeze plug.

[0005] In existing manufacturing processes, the assembly of various components of the antifreeze plug is done manually by assembly workers. However, due to the relatively complex internal structure of the antifreeze plug, the following problems inevitably arise during the assembly process:

[0006] The first issue is the unreasonable assembly sequence. Specifically, during the assembly of the antifreeze plug, the connection relationships between the components are fixed. For example, the valve disc and valve plate are fixedly mounted on the rotating shaft and can rotate with it, while the upper and lower mounting plates are directly fixed to the inner circumferential wall of the antifreeze plug's outer cylinder. The filter tank and the direct current cylinder need to be clamped and fixed between the upper and lower mounting plates after their positions are determined. Therefore, in the overall assembly process, the assembly sequence of each component has a significant impact on assembly efficiency and accuracy. However, in manual assembly, no fixed assembly sequence is formed, the assembly process is chaotic, and components assembled sequentially can easily obstruct each other, leading to operational inconvenience.

[0007] Second, the parts are not convenient to fix during assembly and the assembly position is difficult to adjust. Specifically, for the parts that need to be fixed (mainly the valve disc, valve plate and upper and lower mounting plates), when they are fixed on the assembly carrier by welding or bonding, etc., they are lack of support, and most of the time the assembly workers need to hold the assembly parts while performing the fixing operation. The defect of this operation mode is that it cannot guarantee the accuracy of the assembly position of the parts during assembly, and it is very likely that the assembly deviation of the parts will occur due to the operation error of the workers. In addition, the assembly positions of the upper and lower mounting plates and the valve disc are different for different freeze plugs, and the manual assembly method is difficult to adjust the assembly position according to the actual assembly requirements.

[0008] In summary, the prior art has obvious inconvenience and defects in actual use, so it is necessary to improve. SUMMARY

[0009] In view of the defects in the prior art, the present application provides an assembly auxiliary device for freeze plug production to solve the problems of unreasonable assembly sequence, inconvenient fixing of assembly parts and poor assembly adjustment in the manual assembly method during the assembly process of the freeze plug in the traditional technology.

The output shafts of each rotating drive motor respectively pass through the assembly clamping box and are fixedly connected to the corresponding strip-shaped limiting plate.

[0015] As an optimization scheme, the circular arc clamping opening is fixed on the inner circumferential wall near the lower end of the circular arc clamping opening. A circular support bridge plate is arranged on the inner circumferential wall near the lower end of the circular arc clamping opening. A rotating clamping assembly is arranged on the circular support bridge plate. The rotating clamping assembly comprises a rotating drive motor fixed at the center of the lower surface of the circular support bridge plate. The output shaft of the rotating drive motor penetrates the circular support bridge plate and is fixed with a horizontal rotating seat. The rotating seat is arranged close to the upper surface of the circular support bridge plate. A plurality of center-symmetric limiting clamping jaws are fixed to the upper surface of the circular support bridge plate.

[0016] As an optimization scheme, a vertical lifting telescopic cylinder is fixed at the center of the upper surface of the rotating seat. The upper telescopic end of the lifting telescopic cylinder is fixed with a horizontal telescopic clamping seat.

[0017] As an optimization scheme, the telescopic clamping seat is a flat cylindrical seat. Four center-symmetric telescopic mounting openings are arranged on the circumferential wall of the telescopic clamping seat. A horizontal electric control telescopic rod is fixed to the inner surface of each telescopic mounting opening. An arc-shaped clamping plate is fixed to the telescopic end of each electric control telescopic rod.

[0018] As an optimization scheme, two vertical limiting communication openings are arranged on the outer side wall of the assembly positioning box. A U-shaped limiting frame is slidingly arranged in the two limiting communication openings. The ends of the U-shaped limiting frame penetrate the limiting communication openings and extend into the square mounting opening. Two symmetric fan-shaped supporting plates are fixed to the two ends of the U-shaped limiting frame.

[0019] As an optimization scheme, a vertical sliding limiting groove is arranged on the inner end surface of the square mounting opening. A sliding limiting plate is arranged in the sliding limiting groove. A horizontal intermediate supporting plate is fixed to the end of the sliding limiting plate.

[0020] As an optimization scheme, two symmetric fixed mounting seats are fixed to the opposite side walls near the lower end of the assembly clamping box. Two symmetric sliding mounting seats are fixed to the opposite side walls near the lower end of the assembly positioning box.

The telescopic clamping seat arranged at the lower part of the assembly clamping box can lift and clamp the half cylinder to adjust the position of the half cylinder in the assembly clamping box, and can also drive the half cylinder to rotate 180° after the assembly of the upper and lower mounting plates, valve disc, valve plate and other parts is completed, so that the opening side of the half cylinder faces the assembly avoiding opening arranged on the assembly clamping box, facilitating the installation of the straight-through cylinder and the filter tank. In addition, the assembly clamping box determines the assembly sequence, i.e., the parts are assembled from bottom to top, and the installation of the next part is performed after the complete installation of the previous part, so that the parts to be assembled do not interfere with each other, facilitating operation.

[0027] The assembly positioning box is arranged to adjust the assembly position of each part during assembly, and the adjustment is achieved by controlling the up and down movement of the fan-shaped supporting plate and the intermediate supporting plate.
