Description

Technical Field

[0001] This application belongs to the technical field of condenser manufacturing, and particularly relates to an auxiliary device for installing condenser connecting pipes. Background Art

[0002] The manufacturing process of a condenser includes fin installation, tube threading, tube expanding, flaring, installation of U-shaped connecting pipes, welding of U-shaped connecting pipes, etc. Among them, the installation and welding of U-shaped connecting pipes is to connect the ports of multiple condenser tubes on the condenser main body through U-shaped connecting pipes, so as to penetrate all condenser tubes and improve the cooling effect. In the prior art, before each welding of the U-shaped connecting pipe, it is necessary to manually install the U-shaped connecting pipe onto the corresponding two condenser tube ports in sequence. For condensers with a slightly larger model, the number of condenser tube ports to be connected is very large, and manual installation in sequence is time-consuming and laborious, which is not conducive to improving production efficiency. Summary of the Utility Model

[0003] In order to solve the above deficiencies of the prior art, this application provides an auxiliary device for installing condenser connecting pipes, which can increase the installation speed of U-shaped connecting pipes and improve production efficiency.

[0004] To achieve the above object, the present utility model adopts the following technologies:

[0005] An auxiliary device for installing condenser connecting pipes, comprising:

[0006] A mounting plate, on the top of which several storage boxes are vertically arranged, and the bottom of the storage boxes penetrates through the mounting plate; a lifting mechanism is also arranged on the top of the mounting plate, and its movable end moves along the vertical direction and faces the inside of the storage box;

[0007] Movable rods, which are arranged in pairs at the bottom of the mounting plate. Each pair of movable rods is parallel to each other and arranged to move towards each other. The plane where each pair of movable rods is located is parallel to the mounting plate, and the positions of each pair of movable rods and the bottom of the storage box match each other.

[0008] Further, the movable rods are arranged in pairs between a pair of parallel connecting plates, and the connecting plates are arranged parallel to the movable rods; a guide shaft is vertically provided on one side of the movable rod, and the guide shaft passes through the corresponding connecting plate and is connected with a top plate; a first spring is sleeved on the guide shaft, and the first spring connects the top plate and the connecting plate. When the first spring is in the natural state, the two movable rods abut against each other; the other side of the movable rod is set as an inclined surface, and the inclined surface faces downward of the movable rod.

[0009] Furthermore, the lifting mechanism includes a lifting plate arranged toward the long side direction of the mounting plate, guide rods are vertically arranged on both sides of the top of the mounting plate, both ends of the lifting plate are passed through the corresponding guide rods, a round table is arranged at the far end of the guide rod, a second spring is sleeved on the guide rod, and the second spring connects the lifting plate and the round table; a long groove is opened in the vertical direction downward at the top of the storage box, and when the second spring is in a natural state, the lifting plate is located at the bottom of the long groove.

[0010] The beneficial effects of the utility model are:

[0011] 1. Use a storage box to store multiple U-shaped connecting pipes, and cooperate with the movable end of the lifting mechanism to press the U-shaped connecting pipes in the storage box tightly onto the movable rod. Under the relative movement of the movable rod and the downward pressure applied to the mounting plate, the movable end of the lifting mechanism presses the U-shaped connecting pipe at the bottom into the corresponding condenser pipe port, thereby increasing the speed of batch installation of U-shaped connecting pipes and improving production efficiency.

[0012] 2. Through the setting of the guide shaft, the first spring, and the top plate, and in conjunction with the inclined surface set on the other side of the movable rod, when downward pressure is applied to the mounting plate, the two movable rods are separated from each other due to the interaction between the inclined surface and the condenser tube port, thereby installing the U-shaped connecting tube at the lower end of the storage box on the condenser tube; when the mounting plate is separated from the condenser tube, the tip of the inclined surface abuts against the outer wall of the installed U-shaped connecting tube and moves upward. Since the movable rod and the outer wall of the installed U-shaped connecting tube are in point contact, the problem of the installed U-shaped connecting tube being brought out of the condenser tube port due to excessive friction is avoided. At the same time, after the movable rod is separated from the U-shaped connecting tube, the two movable rods automatically move closer and abut against each other under the action of the first spring, separating the installed U-shaped connecting tube from the previous U-shaped connecting tube, thereby improving the degree of automation of the U-shaped connecting tube installation process and further improving production efficiency.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] The embodiments of the present application provide an auxiliary device for installing a condenser connecting pipe, as Figures 1 to 4 shown, which includes a mounting plate 1. In this embodiment, five storage boxes 2 are vertically arranged on the top of the mounting plate 1. The storage boxes 2 are used to store multiple U-shaped connecting pipes with their ports facing downward vertically. The five storage boxes 2 are evenly arranged along the length direction of the mounting plate 1. The number of the storage boxes 2 can be set according to the actual number of the condenser pipe ports. The bottom of the storage box 2 penetrates through the mounting plate 1. A lifting mechanism 3 is further arranged on the top of the mounting plate 1. Its movable end moves vertically and faces the inside of the storage box 2, and is used to press the U-shaped connecting pipes stored in the storage box 2. Five pairs of movable rods 4 are arranged at the bottom of the mounting plate 1. Each pair of the movable rods 4 is parallel to each other and moves towards each other. The plane where each pair of the movable rods 4 is located is parallel to the mounting plate 1. Each pair of the movable rods 4 matches the position of the bottom of the corresponding storage box 2.

[0021] During application, first, multiple U-shaped connecting pipes are vertically placed into each storage box 2 with their ports facing downward. At this time, each pair of the movable rods 4 is in a state of abutting and is located directly below the bottom of the storage box 2. The movable end of the lifting mechanism 3 extends vertically downward into the storage box 2, and the U-shaped connecting pipes in the storage box 2 are sequentially pressed between the movable end of the lifting mechanism 3 and the top of the movable rod 4. The mounting plate 1 is placed above the condenser pipe, making the condenser pipe perpendicular to the mounting plate 1, and aligning the storage box 2 with the condenser pipe port where the U-shaped connecting pipe needs to be installed. The mounting plate 1 is vertically pressed downward. When the movable rod 4 abuts against two adjacent condenser pipe ports, the two movable rods 4 separate from each other in opposite directions. The two ports of the lowermost U-shaped connecting pipe in the storage box 2 are pressed by the movable end of the lifting mechanism 3 into two adjacent condenser pipe ports. Then, continue to apply a downward pressure to the mounting plate 1, so as to firmly install the U-shaped connecting pipe. When the mounting plate 1 is lifted and the movable rod 4 separates from the installed U-shaped connecting pipe, the two movable rods 4 approach each other and abut, separating the installed U-shaped connecting pipe from the upper U-shaped connecting pipe, thus completing the batch installation of the U-shaped connecting pipe. Only need to press the mounting plate 1 once before each welding, which solves the problem of time-consuming and laborious manual installation one by one, and effectively improves the production efficiency of the condenser.

[0022] Specifically, as Figures 1 to 5 shown, the movable rod 4 is arranged between a pair of parallel connecting plates 41. A guide shaft 42 is vertically provided on one side of the movable rod 4. The guide shaft 42 passes through the corresponding connecting plate 41 and is connected to the top plate 43. A first spring 44 is sleeved on the guide shaft 42 between the top plate 43 and the connecting plate 41. The other side of the movable rod 4 is set as an inclined surface; as Figure 5 shown, the movable end of the lifting mechanism 3 tightly presses the U-shaped connecting pipe against the tops of the two movable rods 4. When the position of the storage box 2 is aligned with the ports of two adjacent condensing pipes, the mounting plate 1 is pressed downwards, so that the inclined surfaces of the two movable rods 4 abut against both sides of the condensing pipe ports. Continuing to press down the mounting plate 1, due to the action of the inclined surface and the condensing pipe ports, the movable rod 4 will abut against the condensing pipe ports and move along the inclined surface, that is, the two movable rods 4 separate from each other; when the movable rods 4 completely move to both sides of the condensing pipe ports, the U-shaped connecting pipe is pressed into the corresponding ports by the movable end of the lifting mechanism 3. Continuously applying a downward pressure to the mounting plate 1, the U-shaped connecting pipe is firmly installed; since the movable rod 4 is in point contact with the outer wall of the installed U-shaped connecting pipe, the problem of pulling out the installed U-shaped connecting pipe from the condensing pipe port due to excessive friction is avoided. At the same time, after the movable rod 4 is separated from the U-shaped connecting pipe, the two movable rods 4 automatically approach and abut against each other under the action of the first spring 44, separating the installed U-shaped connecting pipe from the previous U-shaped connecting pipe, improving the automation degree of the U-shaped connecting pipe installation process and further improving the production efficiency.

[0023] Specifically, as Figure 1 and Figure 5 shown, the lifting mechanism 3 adopts a lifting plate 31 as its movable end and enters the storage box 2 through a long groove 21 opened on the storage box 2. During application, the lifting plate 31 is first pulled out of the storage box 2 to store the U-shaped connecting pipe. After storage is completed, the lifting plate 31 is lowered. The lifting plate 31 automatically presses the U-shaped connecting pipe in the storage box 2 under the elastic force of the second spring 34. And after the movable rod 4 is separated, the downward pressure of the mounting plate 1 can be increased to make the installation of the U-shaped connecting pipe more firm, ensuring the installation effect and eliminating the problem of poor welding caused by poor installation effect. At the same time, the overall structure of the device is optimized.

[0024] Preferably, as Figure 4 and Figure 5 shown, a limiting block 45 adapted to the outer wall of the connecting pipe is provided at the top of the movable rod 4. The limiting block 45 is an arc-shaped block, and its radian is consistent with the roundness of the U-shaped connecting pipe port; when the lifting plate 31 presses the U-shaped connecting pipe against the top of the movable rod 4, the limiting block 45 adheres to both sides of the two ends of the U-shaped connecting pipe, so that when installing the U-shaped connecting pipe, the axes of the two ends of the U-shaped connecting pipe are always aligned with the axes of the corresponding condensing pipe ports, further eliminating the problem of poor welding caused by poor installation effect and improving the installation quality of the U-shaped connecting pipe.

[0025] Preferably, as Figure 1 and Figure 2 shown, two positioning rods 11 are vertically provided at both ends of the bottom of the mounting plate 1, and three positioning rods 11 are vertically provided on both sides of the bottom of the mounting plate 1. During application, the positioning rods 11 are used to abut against the periphery of one end face of the condenser body, which is beneficial to the quick alignment between the storage box 2 and the condenser tube port.

[0026] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
